Clinical use of mood stabilizers beyond treatment for bipolar disorder: The REAP-MS study

OBJECTIVE

Mood stabilizers are psychotropic drugs mainly used to treat bipolar disorder in the acute phase or for maintenance therapy to prevent relapse. In clinical practice, mood stabilizers are commonly prescribed for conditions other than bipolar disorder. This study investigated the distribution of mood stabilizer prescriptions for different psychiatric diagnoses and studied differences in the drugs, dosage, and plasma concentration in 10 Asian countries including Taiwan, South Korea, Malaysia, China, Thailand, India, Pakistan, Singapore, Indonesia, and Myanmar.

METHODS

Patients prescribed mood stabilizers (lithium, carbamazepine, valproic acid, or lamotrigine) for a psychiatric condition other than bipolar disorder (codes F31.0-F31.9 in the International Classification of Diseases, 10th Edition, Clinical Modification) were recruited through convenience sampling. A website-based data entry system was used for data collection.

RESULTS

In total, 1557 psychiatric patients were enrolled. Schizophrenia, schizotypal, delusional, and other non-mood psychotic disorders (F20-F29, 55.8 %) was the most common diagnosis, followed by non-bipolar mood disorders (F30, F31- F39, 25.3 %), organic mental disorder (F00-F09, 8.8 %), mental retardation (F70-F79, 5.8 %) and anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders (F40-F48, 4.4 %). The most frequently targeted symptoms (>20 %) were irritability (48 %), impulsivity (32.4 %), aggression (29.2 %), anger (20.8 %), and psychosis (24.1 %). Valproic acid was the most frequently used medication.

CONCLUSIONS

Clinicians typically prescribe mood stabilizers as empirically supported treatment to manage mood symptoms in patients with diagnoses other than bipolar disorders, though there is on official indication for these disorders. The costs and benefits of this add-on symptomatic treatment warrant further investigation.

957 THE USE OF IPADS AS PART OF PERSON CENTERED CARE IN A TEACHING HOSPITAL IN SINGAPORE

The elderly patients are currently the main occupants of acute hospital beds and this trend will likely increase as the world ages. The elderly patients with cognitive issues frequently have behavioural symptoms which may be challenging for the care staff to manage, especially the staff who have not been formally trained in Gerontology. The use of restraints for this group of vulnerable patients should be discouraged as restraints can cause harmful effects.

The use of iPads as a non pharmacological strategy for managing the behavioural symptoms among the elderly in-patients with cognitive issues was effective in reducing agitation, with an improvement in mood and sundown symptoms. The patients were actively and meaningfully engaged with their iPads during therapy.

The nursing staff too, benefited from iPads as a novel therapy for their elderly in-patients with cognitive issues in providing cognitive and social stimulations, which they had no time to provide for. While the patients showed improvement in their behavioural symptoms, the nurses’ stress levels reduced with improved self-reported job satisfaction.

Prescription Patterns for Bipolar Disorder in Asian Countries: Findings from Research on Asian Prescription Pattern-Bipolar Disorder

Objective

Pharmacotherapy including mood stabilizers and antipsychotics are frequently used in bipolar disorder (BD); however, the lack of consensus regarding the definition of polypharmacy hinders conducting comparative studies across different settings and countries. Research on Asian Prescription Pattern (REAP) is the largest and the longest lasting international collaborative research in psychiatry in Asia. The objective of REAP BD was to investigate the prescription patterns of psychotropic medications across Asian countries. The rates of polypharmacy and psychotropic drug load were also analyzed.

Methods

The data collection was web-based. Prescription patterns were categorized as (1) mood stabilizer monotherapy: one mood stabilizer; (2) antipsychotic monotherapy: one antipsychotic; (3) simple polypharmacy: one mood stabilizer and one antipsychotic; and (4) complex polypharmacy: ≥ 2 mood stabilizers or/and antipsychotics. The psychotropic drug load in each patient was calculated using the defined daily dose method.

Results

Among 2003 patients with BD (52.1% female, 42.4 years) from 12 countries, 1,619 (80.8%) patients received mood stabilizers, 1,644 (82.14%) received antipsychotics, and 424 (21.2%) received antidepressants, with 14.7% mood stabilizer monotherapy, 13.4% antipsychotic monotherapy, 48.9% simple polypharmacy, 20.3% complex polypharmacy, and 2.6% other therapy. The average psychotropic drug load was 2.05 ± 1.40. Results varied widely between countries.

Conclusion

Over 70% of psychotropic regimens involved polypharmacy, which accords with the high prevalence of polypharmacy in BD under a permissive criterion (2 or more core psychotropic drugs) worldwide. Notably, ≥ 80% of our sample received antipsychotics, which may indicate an increasing trend in antipsychotic use for BD treatment.

Mental health of adolescents in Myanmar: A systematic review of prevalence, determinants and interventions

Adolescence is a developmental phase where mental disorders typically manifest and where platforms for response (including schools and health services) change rapidly. However, data to inform public mental health responses are limited, including in countries like Myanmar which has a large adolescent population and where mental health has been identified as a priority of policy. In this paper we sought to systematically review the peer-reviewed and grey literature to determine (i) the prevalence of mental disorder among adolescents in Myanmar, (ii) determinants of mental disorder and (iii) interventions that have been implemented and evaluated. Nine publications met inclusion criteria (7 peer-reviewed and 2 grey literature) that included 7 publications reporting prevalence, 6 reporting correlates and one an intervention. The available data from the 2016 Global School-based Health Survey highlight that depression (27.2%) and suicidal ideation (9.4%) are prevalent in Myanmar, and these rates are substantially higher than regional averages. The limited available data on correlates identified violence and bullying, alcohol and substance use, and home, family and community security and cohesion as being closely related to mental health for adolescents. Only one study focussed on interventions and this found mindfulness meditation training to be an effective approach for young people whose parents were affected by HIV. These findings underscore the need to address adolescent mental health in Myanmar, but also to invest in better data collection efforts.

The burden of Japanese encephalitis, the catch-up vaccination campaign, and health service providers' perceptions in Myanmar: 2012-2017

Background

Myanmar is endemic for Japanese encephalitis (JE) and has experienced several outbreaks in recent years. The vector-borne disease control (VBDC) program has collected hospital-based surveillance data since 1974. There is an urgent need to collate, analyze, and interpret the most recent information. The study aimed to describe (i) hospital-based JE cases and deaths between 2012 and 2017, (ii) a catch-up vaccination campaign in children in 2017, and (iii) health service provider perceptions about JE in one township in 2018.

Methods

This was a cross-sectional study of cases, deaths, and catch-up childhood vaccinations using secondary data from program records and a survey database of health service provider perceptions.

Results

Between 2012 and 2017, there were 872 JE cases and 79 deaths with a case fatality rate of 91 per 1000; 2016 was the year with most cases and deaths. Most cases (n = 324) and deaths (n = 37) occurred in children aged 5–9 years. Large case numbers were reported in delta and lowland regions (n = 550) and during the wet season (n = 580). The highest case fatality rates were observed in the hills and coastal regions (120 and 112 per 1000, respectively). Nationwide coverage of the catch-up JE vaccination campaign among 13.7 million eligible children was 92%, with coverage lower in the hills and coastal regions (84%) compared with delta and lowland regions and plains (94%). More vaccinations (65%) occurred through school-based campaigns with the remainder (35%) vaccinated through community-based campaigns. Structured interviews in one township showed that service providers (n = 47) had good perceptions about various aspects of JE, although perceived benefits of specific vector control measures were poor: spraying/fumigation (38%), garbage removal (36%), larvicide use (36%), and drainage of standing/stagnant water (32%).

Conclusion

The catch-up vaccination campaign was a successful response to high JE case numbers and deaths in children. However, ongoing surveillance for JE needs to continue and be strengthened to ensure comprehensive reporting of all cases, more knowledge is needed on disability in JE survivors, and all attempts must be made to ensure high percentage coverage of vaccination through routine and catch-up campaigns.

Do we need to go further to train healthcare providers in the targeted regions for malaria elimination in Myanmar? A mixed-methods study

Background

The National Malaria Control Programme (NMCP) in Myanmar trained health staff at the township level starting in mid-2016 in order to achieve the Plasmodium falciparum malaria elimination target by 2020. This study aimed to evaluate the knowledge and perception of Basic Health Staff (BHS) and Vector-borne Diseases Control (VBDC) teams exposed to a short training course on malaria elimination in six targeted townships which included two conflict-affected townships between 2016 and 2017.

Methods

This was a cross-sectional mixed-methods study using quantitative and qualitative data extracted from one survey database conducted between October 2018 and March 2019. Modified Poisson regression analysis was performed to ascertain the determinants of low knowledge scores after the training programme.

Results

Altogether, 544 trained frontline health workers involved in malaria elimination at the time of the survey were recruited and 56% (302/544) were stationed at sub-Rural Health Centers. More than half of the respondents had correct knowledge of malaria case categories although relapse and recrudescent cases (39% and 37% respectively) were less well known. Over two-thirds of respondents could mention those eligible for malaria testing. Less than 30% knew the foci classification. The overall knowledge scores ranged from 10 to 31. The significant predictors of low level of knowledge [the cut-off point was set at the median value of 21 (IQR 12-30)] in multivariate analysis were the younger age group (18-29 years) and health staff who had attended malaria elimination training in 2017, [(APR = 1.6, 95% CI 1.2-2.2)]; and (APR = 1.5, 95%CI 1.2-1.8)]. Qualitative data from 10 key informants identified perceived challenges in conflict-affected areas as well as in areas of high population mobility with further implications for case surveillance. In addition, the low level of education of community members was noted as one of the barriers that hampered public readiness in the elimination scenario.

Conclusion

A significant impact on knowledge improvement after the training programme was not visible especially for correct notification of malaria cases and treatment according to National Malaria Elimination Guidelines. Regular monitoring and continuing guidance by the higher level management is critical to support the field staff.

The prevalence of mental distress and the association with education: a cross-sectional study of 18-49-year-old citizens of Yangon Region, Myanmar

Background

Poor mental health is an important contributor to the global burden of disease. Mental health problems are often neglected in communities, and are scarcely studied in developing countries, including Myanmar. This study estimates the prevalence of mental distress by socio-demographic and health related factors, and the association between education and mental distress. As far as the authors are aware, this is the first population-based study in Myanmar estimating the prevalence of mental distress.

Methods

Between October and November 2016, a cross sectional study was conducted using a multi-stage sampling design with face-to-face interviews using the Hopkins Symptom Checklist (HSCL-10) for mental distress (symptoms of depression and anxiety). The multivariable analysis strategy was based on Directed Acyclic Graphs (DAGs), to identify confounders, mediators and colliders. Pearson’s chi-square was used for testing differences between proportions and multiple linear regression analysis was applied to explore the association between education (years at school) and mental distress (HSCL score).

Results

A random sample of 2391 (99.6% response) men and women aged 18–49 years participated in the study. The prevalence of mental distress was 18.0% (95% confidence interval (CI): 14.7–21.9), being higher among women (21.2%; 95% (CI): 16.6–26.6) than men (14.9%; 95% (CI): 11.4–19.2). Older-age, being separated or divorced and having a higher number of children were associated with increased mental distress. In linear regression analyses, adjusted for confounders (age, marital status and income), there was a significant negative association between years at school and mental distress among women and older men (> 30 years), but not among the youngest men.

Conclusions

The prevalence of mental distress is high, and there is an association between HSCL-10 score and education. Due to the scarcity of mental health services in Myanmar, the findings indicate a need for a mental health policy to handle the burden of mental health problems in Yangon, a burden which is probably high within the country.

Utilization of insecticide-treated bed nets and care-seeking for fever and its associated socio-demographic and geographical factors among under-five children in different regions: evidence from the Myanmar Demographic and Health Survey, 2015-2016

Background

Malaria is one of the top-five contributors to under-5 deaths in Myanmar. Use of insecticide-treated nets (ITN) and receiving early appropriate care in case of fever are the core interventions to prevent malaria and its complications and thereby deaths. This study aimed to assess among the under-five children, (a) utilization of ITNs and its associated factors, (b) care-seeking behaviour among their caregivers and its associated factors and uptake of malaria testing among those with fever in the last 2 weeks.

Methods

This was a cross sectional study using secondary analysis of Myanmar Demographic and Health Survey (MDHS) conducted in 2015–2016. Multivariable logistic regression was used to explore the factors associated with non-utilization of ITNs and not seeking care for fever. Effect sizes have been presented using odds ratios with 95% confidence intervals. Data analysis was done using svyset command in STATA to account for the multi-stage sampling design of the survey.

Results

Of 4597 alive under-five children, 80.5% did not sleep under an ITN last night. The factors significantly associated with non-utilization of ITNs were residing in malaria elimination regions (aOR = 2.0, 1.3–3.2), urban residence (aOR = 1.8, 1.2–2.9), staying in delta region (aOR = 8.7, 4.7–12.2), hilly region (aOR = 3.0, 2.0–4.6, and having highest wealth quintile (aOR = 1.8, 1.1–3.0). Around 16% had fever in the last 2 weeks, of whom 66.7% sought care for fever and 3% got tested for malaria. Nearly half (50.9%) of the caregivers sought care from a government health facility, followed by private hospital/doctor (27.8%), shop (8.0%), village health worker (4.4%) and pharmacy (3.1%). The factors associated with not seeking care for fever were residing in specific geographical locations (hilly, delta and central plains compared to coastal region) and having lowest wealth quintile (aOR = 2.3, 1.1–5.7).

Conclusions

This study highlighted that ownership and utilization of ITNs was very poor among under-5children. Care-seeking behaviour of the caregivers of under-5 children in case of fever was dismal with two-thirds not seeking care. The programme should seriously consider addressing these barriers if Myanmar is to achieve zero malaria deaths by 2030.

Child and adolescent psychiatry in the Far East: A 5-year follow up on the Consortium on Academic Child and Adolescent Psychiatry in the Far East (CACAP-FE) study

AIM

Data pertaining to child and adolescent psychiatry (CAP) training systems are limited as extant research has mostly been derived from one-time data collection. This 5-year follow-up survey collects updated information on CAP training systems in the Far East, allowing for the tracking of system changes over the past 5 years.

METHODS

Data were obtained from 18 countries, or functionally self-governing areas, in the Far East, 17 of which were also included in the original study. An online questionnaire was completed by leading CAP professionals in each country. Questions were expanded in the present study to capture the contents of CAP training.

RESULTS

When compared to data from the original study, there has been progress in CAP training systems in the last 5 years. Specifically, there has been an increase in the number of countries with CAP training programs and national guidelines for the training. In addition, the number of CAP departments/divisions affiliated with academic institutions/universities has increased. Findings from 12 of 18 countries in the present study provide data on clinical contents. All informants of the present study reported the need for more child and adolescent psychiatrists and allied professionals.

CONCLUSION

Despite progress in CAP training systems over the last 5 years, the need for more professionals in child and adolescent mental health care in all the relevant areas in this region have yet to be adequately addressed. Continued national efforts and international collaborations are imperative to developing and sustaining new CAP training systems while facilitating improvements in existing programs.

Emerging neglected helminthiasis and determinants of multiple helminth infections in flood-prone township in Myanmar

Background

Myanmar has similar agro-based ecology and environmental risks as others in the Greater Mekong sub-region leading to the broad array of helminthic infections. Basic health staff (BHS) from the public sector forms a key stakeholder group in deworming interventions. The study aimed to ascertain the prevalence and determinants of multiple species helminth infections to promote township-level integrated interventions.

Methods

A cross-sectional implementation research study in 2017 covered randomly selected 240 households in four villages of Shwegyin Township. Trained interviewers administered the pre-tested structured questionnaire to either the household head or the assigned person concerning their knowledge, perceptions, practices, food habits, and deworming experience. Concomitantly, the research team collected a single stool sample from each of 698 participants (age range of 8 months to 87 years) from 93% (224/240) of eligible households and examined by Kato-Katz smear microscopy. Eventually, 16 BHS joined the interactive dialogue session based on research evidence and knowledge translated for further validation.

Results

The estimated prevalence of at least one helminth infection was 24% [168/698; 95% CI 21.0–27.0]. Apart from the soil-transmitted helminths (14%), zoonotic helminths especially Taenia spp. (0.7%) and Schistosoma spp. (3%) were detected. Almost half of the seasonally mobile gold panning workers (12/25; 48%) and 46% of pre-school-age children had helminth infections. Community risk groups at riverside villages had significantly higher multiple species helminth infection than those from inland villages (AOR = 10.9; 95% CI 4.9–24.2). Gold panning workers had higher infection rates than other categories (AOR = 2.5; 95% CI 0.6–9.5) but not significant. In flood-prone areas, householders failed to follow the guidelines to construct/re-construct specific type of sanitary latrines and challenges remained in disseminating health messages for community engagement. The innovative ideas recapitulated by BHS included the integration of health talks during the sessions for small agricultural loans and to harness advocacy with water, sanitation, and hygiene interventions.

Conclusions

The emerging evidence of neglected zoonotic helminths required attention to introduce the periodic mopping-up and the “selective deworming plan” for vulnerable groups to cover the missed targets. Further multidisciplinary research to confirm the intermediate hosts and vectors of zoonotic helminths in the environment is essential for surveillance and response.

Access to primaquine in the last mile: challenges at the service delivery points in pre-elimination era, Myanmar

BACKGROUND

Alongside monitoring of the disease burden, the successful move towards malaria elimination relies on the readiness of the health care delivery system. However, there is a lack of evidence in the gap of existing National Guidelines and access to low dose primaquine in real practice under varying degrees of antimalarial resistance in the pre-elimination phase in Myanmar. Therefore, this study addressed the essential information from the service delivery points (SDPs) of public and private sectors on the availability and the use of primaquine in both supply and demand side. Concomitantly, the study aimed to underscore challenges in health system infrastructure to promote the sustained flow in rolling out primaquine in line with National Guidelines for malaria elimination.

METHODS

A cross-sectional study conducted from September 2017 to February 2018 included six townships of three states/regions. The team used an observation checklist for documenting primaquine supplies at SDPs. Semi-structured interviews, key informant, and in-depth interviews focused both public and private sectors including staff from the Vector-Borne Diseases Control (VBDC) teams in each state/region and rural health centers (n = 25), those from the non-governmental organizations (NGOs), general practitioners and drug sellers (n = 11), and recently infected malaria patients (n = 11). Triangulation of quantitative and qualitative data provided meaningful interpretations.

RESULTS

Public sector staff reported an adequate stock of primaquine, but it was unavailable at the general practitioners' clinics without any connection to NGOs and also at the unlicensed drug shops. Health care providers of the public sector experienced challenges in poor compliance of malaria patients to primaquine treatment in conjunction with an artemisinin-based combination therapy, loss-to-follow-ups especially in conflict areas, and delays in timely substitution of new batches of primaquine. Respondents from the private sector demanded for the refresher training course on updated antimalarial treatment guidelines.

CONCLUSION

Monitoring compliance and safety of primaquine treatment was found as a barrier especially among mobile migrant workers and those who were in conflict areas. An alternative strategy by the NMCP could enable to prevent the underutilization of primaquine in vivax malaria to reach the malaria elimination targets.

Household ownership and utilization of insecticide-treated nets under the Regional Artemisinin Resistance Initiative in Myanmar

Background

Malaria is a major public health problem in Myanmar with reported artemisinin resistance. Myanmar promotes the use of insecticide-treated nets (ITNs) through the free delivery of long-lasting insecticide nets (LLINs) with target coverage of at least 80% in moderate and high-risk areas by 2014. Migrant people are at greater risk of malaria. They have significant barriers to health care services for febrile illness and malaria. Thus, a community-based survey was conducted among the migrant population to assess the ownership and utilization of bed nets (ITN/LLINs) for malaria.

Methods

The study analyzed secondary data from a community-based malaria survey conducted in 2014 among migrant population in 30 randomly selected townships out of 52 Regional Artemisinin Resistance Initiative (RAI) townships. In each township, five migrant sites were randomly selected (total of 150 migrant sites). A total of 3933 households (approximately 125 households from each township) were selected.

Results

Of 3923 households assessed, 97% had access to at least one bed net (any type), but only half had access to ITN/LLINs. Only 24% of households had adequate ITN/LLIN access (at least one ITN/LLIN per two persons). In terms of household utilization, 94.3% slept under a bed net (any type) the previous night. Only 43.4% slept under an ITN/LLIN. ITN/LLIN utilization in children under 5 years and pregnant women (high-malaria risk groups) was 45.3 and 46.6%, respectively. Of all nets, 31.3% had holes or had already undergone repairs. In terms of insecticide treatment status, 52.9% of bed nets were untreated and 35.9% of ITNs had not been treated with insecticide for more than a year.

Conclusion

This study highlights poor access and high utilization of ITN/LLINs among migrant population, particularly among children and pregnant women. It highlights the need for improving bed net coverage and access to ITN/LLINs through bed net distributions and/or social marketing with the focus on migrant population and targeting of households with children and pregnant women.

Rapid progress towards elimination of lymphatic filariasis in endemic regions of Myanmar as a result of 16 years of anti-filarial activities (2001-2016)

Background

As Myanmar progresses towards lymphatic filariasis (LF) elimination, it is important to know how well the anti-filarial activities have performed. The present study was conducted to study the implementation of the key anti-filarial activities and their impact on key indicators of LF transmission.

Methods

A secondary analysis of aggregate program data on the anti-filarial activities was conducted in four endemic state/regions of Myanmar receiving at least six mass drug administration (MDA) rounds during 2001-2016.

Results

MDA coverage has been expanded to cover all the endemic implementation units (IUs), i.e., 45 by 2015 and 6 IUs out of them have already stopped MDA. The reported coverage of MDA ranges from 87 to 100% whereas surveyed coverage ranges from 78 to 100% among the eligible population. The prevalence of microfilaria has significantly declined especially in Magway from 4.7 to 0.2% and Sagaing region from 7.9 to 1.3% during 2001-2016. Around 2.5% of estimated cases of hydrocele were reported to the program during 2009-2014.

Conclusion

Myanmar has achieved significant success in interrupting LF transmission through several MDA rounds with high coverage. However, morbidity reporting and management, being in its initial phase requires an active surveillance system for identifying and managing people with LF-associated morbidities under the program.

Assessment of household ownership of bed nets in areas with and without artemisinin resistance containment measures in Myanmar

BACKGROUND

Myanmar lies in the Greater Mekong Subregion where there is artemisinin-resistant Plasmodium falciparum malaria. As the artemisinin compound is the pillar of effective antimalarial therapies, containing the spread of artemisinin resistance is a national and global priority. The use of insecticide-treated bed nets/long-lasting insecticidal nets (ITNs/LLINs) is the key intervention for ensuring the reduction of malaria transmission and the spread of resistant strains, and for eventually eliminating malaria. This study aimed at assessing household ownership of, access to, and utilization of bed nets in areas of Myanmar with and without artemisinin resistance containment measures.

METHODS

Secondary data from a nationwide community-based malaria survey conducted by the National Malaria Control Program in 2014 were analyzed. Based on evidence of artemisinin resistance, Myanmar was divided into tiers 1, 2, and 3: townships in tiers 1 and 2 were aggregated as the Myanmar Artemisinin Resistance Containment (MARC) areas and were compared with tier 3 townships, which were defined as non-MARC areas. The chi-square test was used to compare groups, and the level of significance was set at P ≤ 0.05.

RESULTS

Of the 6328 households assessed, 97.2% in both MARC and non-MARC areas had at least one bed net (any type), but only 63% of households had ITNs/LLINs. Only 44% of households in MARC areas and 24% in non-MARC areas had adequate numbers of ITNs/LLINs (one ITN/LLIN per two persons, P <  0.001). Nearly 44% of household members had access to ITNs/LLINs. Regarding the utilization of ITNs/LLINs, 45% of household members used them in MARC areas and 36% used them in non-MARC areas (P <  0.001, desired target = 100%). Utilization of ITNs/LLINs among children aged below five years and pregnant women (high malaria risk groups) was low, at 44% and 42%, respectively.

CONCLUSIONS

This study highlights the nationwide shortfalls in the ownership of, access to, and utilization of ITNs/LLINs in Myanmar, which is of particular concern in terms of containing the spread of artemisinin resistance. It highlights the need for priority attention to be paid and mobilization of resources in order to improve bed net coverage and utilization through bed net distribution and/or social marketing, information dissemination, and awareness-raising.

Awareness of malaria and treatment-seeking behaviour among persons with acute undifferentiated fever in the endemic regions of Myanmar

Background

Myanmar has a high burden of malaria with two-third of the population at risk of malaria. One of the basic elements of the Roll Back Malaria Initiative to fight against malaria is early diagnosis and treatment within 24 h of fever. Public awareness about malaria is a key factor in malaria prevention and control and in improving treatment-seeking behaviour.

Methods

A large community-based survey was carried out in 27 townships of malaria endemic regions in Myanmar in 2015 which reported on the knowledge, behaviour and practices around malaria in the general population. We used the data already collected in this survey to assess (i) general public awareness of malaria and (ii) treatment-seeking behaviour and associated factors among persons with acute undifferentiated fever.

Results

A total of 6597 respondents from 6625 households were interviewed (response rate of 99.5%). About 85% of the respondents were aware that mosquito bite was the mode of transmission of malaria and 90% mentioned that malaria was preventable. However, only 16% of the respondents knew about anti-malaria drug resistance. There were certain misconceptions about the transmission of malaria such as dirty water, same blood group, sharing shelter, sleeping/eating together and poor hygiene. Health facility staff were the most common source of information about malaria (80%). Nearly one-fourth (23%) of the respondents with fever resorted to self-medication. Around 28% of the respondents with fever underwent blood testing, less than half of whom (44%) were tested within 24 h. Elderly age group, females, those with poor knowledge about malaria and those residing in non-Regional Artemisinin Resistance Initiative townships were associated with poor treatment-seeking behaviour in case of fever.

Conclusion

Although there is fair knowledge on mosquito bite as a mode of transmission and prevention of malaria, there are some misconceptions about transmission of malaria. Those having poor knowledge about malaria have poor treatment-seeking behaviour. A considerable number of respondents seek care from informal care providers and seek care late. Thus, there is a need to promote awareness about the role of early diagnosis and appropriate treatment and address misconceptions about transmission of malaria.

Understanding malaria treatment-seeking preferences within the public sector amongst mobile/migrant workers in a malaria elimination scenario: a mixed-methods study

Background

Migration flows and the emerging resistance to artemisinin-based combination therapy in the Greater Mekong Sub-region (GMS) create programmatic challenges to meeting the AD 2030 malaria elimination target in Myanmar. The National Malaria Control Programme (NMCP) targeted migrant workers based mainly on the stability of their worksites (categories 1: permanent work-setting; categories 2 and 3: less stable work-settings). This study aims to assess the migration patterns, malaria treatment-seeking preferences, and challenges encountered by mobile/migrant workers at remote sites in a malaria-elimination setting.

Methods

A mixed-methods explanatory sequential study retrospectively analysed the secondary data acquired through migrant mapping surveys (2013–2015) in six endemic regions (n = 9603). A multivariate logistic regression model was used to ascertain the contributing factors. A qualitative strand (2016–2017) was added by conducting five focus-group discussions (n = 50) and five in-depth interviews with migrant workers from less stable worksites in Shwegyin Township, Bago Region. The contiguous approach was used to integrate quantitative and qualitative findings.

Results

Among others, migrant workers from Bago Region were significantly more likely to report the duration of stay ≥ 12 months (63% vs. 49%) and high seasonal mobility (40% vs. 35%). Particularly in less stable settings, a very low proportion of migrant workers (17%) preferred to seek malaria treatment from the public sector and was significantly influenced by the worksite stability (adjusted OR = 1.4 and 2.3, respectively for categories 2 and 1); longer duration of stay (adjusted OR = 3.5); and adjusted OR < 2 for received malaria messages, knowledge of malaria symptoms and awareness of means of malaria diagnosis. Qualitative data further elucidated their preference for the informal healthcare sector, due to convenience, trust and good relations, and put migrant workers at risk of substandard care. Moreover, the availability of cheap anti-malarial in unregistered small groceries encouraged self-medication. Infrequent or no contact with rural health centres and voluntary health workers worsened the situation.

Conclusions

Mitigating key drivers that favour poor utilization of public-sector services among highly mobile migrant workers in less stable work-settings should be given priority in a malaria-elimination setting. These issues are challenging for the NMCP in Myanmar and might be generalized to other countries in the GMS to achieve malaria-elimination goals. Further innovative out-reach programmes designed and implemented specific to the nature of mobile/migrant workers is crucial.

The burden of dengue, source reduction measures, and serotype patterns in Myanmar, 2011 to 2015-R2

Background

Myanmar is currently classified as a high burden dengue country in the Asian Pacific region. The Myanmar vector-borne diseases control (VBDC) program has collected data on dengue and source reduction measures since 1970, and there is a pressing need to collate, analyze, and interpret this information. The aim of this study was to describe the burden of hospital-based dengue disease, dengue control measures, and serotype patterns in Myanmar between 2011 and 2015.

Methods

This was a cross-sectional study using annual records from the Dengue Fever/Dengue Hemorrhagic Fever Prevention and Control Project in Myanmar.

Results

Between 2011 and 2015, there were a total of 89,832 cases and 393 deaths in hospitals, with 97% of cases being in children. In 2013 and 2015, there was an increased number of cases, respectively at 21,942 and 42,913, while during the other 3 years, numbers ranged from 4738 to 13,806. The distribution of dengue deaths each year mirrored the distribution of cases. Most cases (84%) occurred in the wet season and 54% occurred in the delta/lowlands. Case fatality rate (CFR) was highest in 2014 at 7 per 1000 dengue cases, while in the other years, it ranged from 3 to 5 per 1000 cases. High CFR per 1000 were also observed in infants < 1 year (CFR = 8), adults ≥ 15 years (CFR = 7), those with disease severity grade IV (CFR = 17), and those residing in hilly regions (CFR = 9). Implementation and coverage of dengue source reduction measures, including larval control, space spraying, and health education, all increased between 2012 and 2015, although there was low coverage of these interventions in households and schools and for water containers. In the 2013 outbreak, dengue virus serotype 1 predominated, while in the 2015 outbreak, serotypes 1, 2, and 4 were those mainly in circulation.

Conclusion

Dengue is a serious public health disease burden in Myanmar. More attention is needed to improve monitoring, recording, and reporting of cases, deaths, and vector control activities, and more investment is needed for programmatic research.

Knowledge, access and utilization of bed-nets among stable and seasonal migrants in an artemisinin resistance containment area of Myanmar

Background

Myanmar lies in the Greater Mekong sub-region of South-East Asia faced with the challenge of emerging resistance to artemisinin combination therapies (ACT). Migrant populations are more likely than others to spread ACT resistance. A vital intervention to reduce malaria transmission, resistance spread and eliminate malaria is the use of bed nets. Among seasonal and stable migrants in an artemisinin resistance containment region of Myanmar, we compared a) their household characteristics, b) contact with health workers and information material, and c) household knowledge, access and utilization of bed nets.

Methods

Secondary data from community-based surveys on 2484 migrant workers (2013 and 2014, Bago Region) were analyzed of which 37% were seasonal migrants. Bed net access and utilization were assessed using a) availability of at least one bed net per household, and b) one bed net per two persons, and c) proportion of household members who slept under abed net during the previous night (Indicator targets = 100%).

Results

Over 70% of all migrants were from unstable work settings with short transitory stays. Average household size was five (range 1–25) and almost half of all households had children under-five years. Roughly 10 % of migrants were night-time workers.

Less than 40% of households had contact with health workers and less than 30% had exposure to information education and communication (IEC) materials, the latter being significantly lower among seasonal migrants. About 70% of households were aware of the importance of insecticide-treated bed-nets/long-lasting insecticidal nets (ITNs/LLINs), but knowledge on insecticide impregnation and retreatment of ITNs was poor (< 10%).

Although over 95% of households had access to at least one bed net, the number with one bed net per two persons was grossly inadequate (13% for stable migrants and 9% for seasonal migrants, P = 0.001). About half of all household members slept under a bed net during the previous night.

Conclusions

This study reveals important short-falls in knowledge, access and utilization of bed nets among migrants in Myanmar. Possible ways forward include frequent distribution campaigns to compensate for short transitory stays, matching household distributions to household size, enhanced information campaigns and introducing legislation to make mosquito repellents available for night-time workers at plantations and farms. Better understanding through qualitative research is also merited.

Malaria profiles and challenges in artemisinin resistance containment in Myanmar

Background

This study examined evolving malaria profiles from January, 2010 to December, 2014 to evaluate achievements and challenges of implementing measures to prevent and control spread of artemisinin resistance in Myanmar.

Methods

Using National Malaria Control Programme (NMCP) data, a cross-sectional descriptive study of 52 townships in artemisinin-resistant containment areas in Myanmar was conducted. Annual program data were analysed, and trends over time are graphically presented.

Results

In the 52 study townships populated by 8.7 million inhabitants, malaria incidence showed a decreasing trend from 10.54 per 1 000 population in 2010 to 2.53 in 2014, and malaria mortalities also decreased from 1.83 per 100 000 population in 2010 to 0.17 in 2014. The proportion of confirmed to total tested malaria cases also decreased from 6 to 1%, while identification of cases improved. All cases from all parasites species, including Plasmodium falciparum, decreased. Coverage of LLIN (long-lasting insecticidal net)/ITN (insecticide-treated mosquito nets) and indoor residual spraying (IRS) was high in targeted areas with at-risk persons, even though the total population was not covered. In addition to passive case detection (PCD), active case detection (ACD) was conducted in hard-to-reach areas and worksites where mobile migrant populations were present. ACD improved in most areas from 2012 to 2014, but continues to need to be strengthened.

Conclusions

The findings provide useful data on the malaria situation in artemisinin-resistant initiative areas, which may be useful for the NMCP to meet its elimination goal. These profiles could contribute to better planning, implementation, and evaluation of intervention activities.

Evaluation of the behaviour change communication and community mobilization activities in Myanmar artemisinin resistance containment zones

Background

Behaviour change communication (BCC) can improve malaria prevention and treatment behaviour. As a one of the activities under Myanmar Artemisinin Resistance Containment (MARC) programme, BCC have been conducting. This study aimed to evaluate the effectiveness of the behaviour change communication and community mobilization activities in MARC zones in Myanmar.

Methods

A cross sectional descriptive survey was conducted in randomly selected 16 townships in Tier I and II areas of MARC zones by quantitative and qualitative approaches.

Results

In 832 households resided by 4664 people, there were 3797 bed nets. Around 54 % were untreated while 45.6 % were insecticide-treated nets (ITN) and 36.2 % were long-lasting insecticide-treated nets (LLINs). Proportion of households with at least one ITN was 625 (75.12 %), proportion of households with at least one ITN for every two peoples was 487 (58.53 %), and proportion of existing ITNs used in previous night was 1225 (70.65 %) respectively. Nearly 23 % of households had old nets while 52 % had new and unused extra bed nets reflecting the adequacy. Interestingly, 38 % could not mention the benefit of the use of ITN/LLINs. Although 88.2 % knew the disease “malaria”, 11.9 % could not be able to mention the symptoms. More than 80 % provided correct responses that mosquito bite can cause malaria while only 36.9 % could mention the blood test for malaria diagnosis. Only 36.6 % received malaria information within previous year but nearly 15 % could not recognize it. Mostly, 80 % of fever episodes were treated at rural health centers (38.24 %) followed by drug shops (17.65 %) and private clinics (16.18 %) respectively.

Conclusions

Efforts should focus on correcting misconceptions about malaria transmission, prevention and universal use of ITN/LLINs. Although BCC activities have been documented, it is still necessary to intensify community mobilization through all accessible multiple channels in MARC areas.

Mobility dynamics of migrant workers and their socio-behavioral parameters related to malaria in Tier II, Artemisinin Resistance Containment Zone, Myanmar

Background

Areas with dynamic population movements are likely to be associated with higher levels of drug-resistant malaria. Myanmar Artemisinin Resistance Containment (MARC) Project has been launching since 2012. One of its components includes enhancing strategic approaches for mobile/migrant populations. We aimed to ascertain the estimated population of mobile migrant workers and their families in terms of stability in work setting in townships classified as tier II (areas with significant inflows of people from areas with credible evidence of artemisinin resistance) for Artemisinin resistance; to identify knowledge, attitudes and practices related to prevention and control of malaria and to recommend cost-effective strategies in planning for prevention and control of malaria.

Methods

A prospective cross-sectional study conducted between June to December 2013 that covered 1,899 migrant groups from 16 tier II townships of Bago Region, and Kayin and Kayah States. Trained data collectors used a pre-tested and subsequently modified questionnaire and interviewed 2,381 respondents. Data of migrant groups were analyzed and compared by category depending upon the stability of their work setting.

Results

The estimated population of the 1,899 migrant groups categorized into three on the nature of their work setting was 56,030. Bago region was the commonest reported source of origin of migrant groups as well as their transit. Malaria volunteers were mostly within the reach of category 1 migrant groups (43/66, 65.2 %). Less stable migrant groups in category 3 had limited access to malaria information (14.7 %) and malaria care providers (22.1 %), low level of awareness and use of long-lasting insecticide-treated nets (46.6 and 38.8 %). Also, they had poor knowledge on malaria prevention on confirming suspected malaria and on using artemisinin combined therapy (ACT). Within two weeks prior to the survey, only 16.5 % of respondents in all categories combined reported acute undifferentiated fever.

Discussion and Conclusions

Mobility dynamics of migrant groups was complex and increased their vulnerability to malaria. This phenomenon was accentuated in less stable areas. Even though migrant workers were familiar with rapid diagnostic tests for malaria, ACT still needed wide recognition to improve practices supportive of MARC including the use of appropriate personal protection. High mobility calls for re-designation of tier II townships to optimize ACT resistance containment.

Spatial distribution, work patterns, and perception towards malaria interventions among temporary mobile/migrant workers in artemisinin resistance containment zone

BACKGROUND

Mobile populations are at a high risk of malaria infection and suspected to carry and spread resistant parasites. The Myanmar National Malaria Control Programme focuses on preventive interventions and vector control measures for the temporary mobile/migrant workers in Myanmar Artemisinin Resistance Containment Zones.

METHODS

A prospective cross-sectional study was conducted in 2012 in Kawthaung and Bokepyin townships of Tanintharyi Region, Myanmar, covering 192 mobile/migrant aggregates. The objectives were to identify the spatial distribution of the mobile/migrant populations, and to assess knowledge, attitudes, perceptions, and practices concerning malaria prevention and control, and their preferred methods of interventions. The structure of the 192 migrant aggregates was investigated using a migrant mapping tool. Individual and household information was collected by structured interviews of 408 respondents from 39 aggregates, supplemented by 12 in-depth interviews of health care providers, authorities, volunteers, and employers. Data were analyzed by triangulating quantitative and qualitative data.

RESULTS

The primary reasons for the limitation in access to formal health services for suspected malaria within 24 hours were identified to be scattered distribution of migrant aggregates, variable working hours and the lack of transportation. Only 19.6% of respondents reported working at night from dusk to dawn. Among study populations, 73% reported a perceived risk of contracting malaria and 60% reported to know how to confirm a suspected case of malaria. Moreover, only 15% was able to cite correct antimalarial drugs, and less than 10% believed that non-compliance with antimalarial treatment may be related to the risk of drug resistance. About 50% of study population reported to seeking health care from the public sector, and to sleep under ITNs/LLINs the night before the survey. There was a gap in willingness to buy ITNs/LLINs and affordability (88.5% vs. 60.2%) which may affect their sustained and consistent use. Only 32.4% across all aggregates realized the importance of community participation in effective malaria prevention and control.

CONCLUSIONS

Community-based innovative approaches through strong collaboration and coordination of multi-stakeholders are desirable for relaying information on ITNs/LLINs, rapid diagnostic test, and artemisinin combination therapy and drug resistance successfully across the social and economic diversity of mobile/migrant aggregates in Myanmar.

Community-centred eco-bio-social approach to control dengue vectors: an intervention study from Myanmar

Objectives

To build up and analyse the feasibility, process, and effectiveness of a partnership-driven ecosystem management intervention in reducing dengue vector breeding and constructing sustainable partnerships among multiple stakeholders.

Methods

A community-based intervention study was conducted from May 2009 to January 2010 in Yangon city. Six high-risk and six low-risk clusters were randomized and allocated as intervention and routine service areas, respectively. For each cluster, 100 households were covered. Bi-monthly entomological evaluations (i.e. larval and pupal surveys) and household acceptability surveys at the end of 6-month intervention period were conducted, supplemented by qualitative evaluations.

Intervention description

The strategies included eco-friendly multi-stakeholder partner groups (Thingaha) and ward-based volunteers, informed decision-making of householders, followed by integrated vector management approach.

Findings

Pupae per person index (PPI) decreased at the last evaluation by 5.7% (0.35–0.33) in high-risk clusters. But in low-risk clusters, PPI remarkably decreased by 63.6% (0.33–0.12). In routine service area, PPI also decreased due to availability of Temephos after Cyclone Nargis. As for total number of pupae in all containers, when compared to evaluation 1, there was a reduction of 18.6% in evaluation 2 and 44.1% in evaluation 3 in intervention area. However, in routine service area, more reduction was observed. All intervention tools were found as acceptable, being feasible to implement by multi-stakeholder partner groups.

Conclusions

The efficacy of community-controlled partnership-driven interventions was found to be superior to the vertical approach in terms of sustainability and community empowerment.

Location of urethral arteries by colour Doppler ultrasound

STUDY DESIGN

A case report.

SETTING

Regional Spinal Injuries Centre, Southport, UK.

CASE REPORT

A 56-year-old male with complete paraplegia at T-4 underwent visual internal urethrotomy of bulbous urethral stricture with a cold knife at 12 o'clock position. There was brisk arterial bleeding. Despite receiving antibiotics, this patient developed hypotension, tachycardia and tachypnoea. He was resuscitated and mechanical ventilation was instituted. After he recovered from this life-threatening episode of urinary tract-related sepsis, colour Doppler ultrasound imaging of bulbous urethra was performed to locate urethral arteries. In the bulbous urethra, single urethral artery was seen at 12 o'clock position.

CONCLUSION

Since the sites of urethral arteries vary among patients, it is advisable to assess individually the location of urethral arteries preoperatively and plan the site of incision accordingly. Persons with injury to cervical or upper dorsal spinal cord have decreased cardiac and respiratory reserve as well as alteration in immune function. Therefore, all possible measures should be taken to prevent acute blood loss and bacteraemia in this group of patients.

Do spinal cord injury patients always get the best treatment for neuropathic bladder after discharge from regional spinal injuries centre?

OBJECTIVE

To draw attention to inadequate care received by some spinal cord injury patients after discharge from the regional spinal injury center.

SETTING

Regional Spinal Injuries Centre, Southport, UK.

METHODS

Presence of the urethral stricture was not recognised in a 69-year-old male with T-3 paraplegia, who attended a health-care facility with a urinary infection. A Foley catheter was inserted into the urethra only half-way and the catheter balloon was then inflated in the urethra distal to the stricture. In a 68-year-old male with T-8 paraplegia, a long-term indwelling catheter was eroding the urethra and he developed a severe degree of hypospadias while being managed in the community. A 49-year-old male with C-4 tetraplegia developed recurrent urine infections. He received several courses of antibiotics, which were prescribed by community health professionals. But he continued to be unwell. Subsequently, the patient was admitted to a district general hospital, where he was diagnosed to have mild chest infection and was about to be sent home. However, his wife was not happy, and then ultrasound of abdomen was taken, which revealed pyonephrosis. He was then transferred to a spinal unit.

RESULTS

: These patients were not seen promptly in a regional spinal injury centre when they developed medical problems. The complications, which ensued, might have been prevented if expert medical treatment had been provided without delay.

CONCLUSION

In order to meet the needs of a growing population of persons living in the community with spinal cord injury, more beds are required in spinal units. Provision of day surgery wards within spinal units, out-reach clinics and home visits by spinal cord clinicians may reduce the demand for admission in a spinal unit. Education of community health professionals on delayed complications of spinal cord injury, and good communication between spinal cord clinicians, patients, carers, and community health professionals by telephone, e-mail or conventional postal system are likely to improve the care of spinal cord injury patients after discharge from spinal injury centres. Spinal cord clinicians should adopt a patient-centred care instead of the traditional, paternalistic, doctor-centred care.

Delayed complications of discontinuation of intrathecal baclofen therapy: resurgence of dyssynergic voiding, which triggered off autonomic dysreflexia and hydronephrosis

STUDY DESIGN

Case report.

OBJECTIVES

To report insidious development of autonomic dysreflexia and hydronephrosis due to dyssynergic voiding following discontinuation of intrathecal baclofen therapy.

SETTING

Regional Spinal Injuries Centre, Southport, UK.

METHODS

A male patient with paraplegia at T-5 (ASIA-A) had implantation of Medtronic Synchromed 8615 s programmable pump to control intractable spasms. After 4 years, the baclofen pump needed replacement because of battery exhaustion. At this time, he was taking oxybutynin 2.5 mg twice a day. He wore a penile sheath and performed intermittent catheterisation three times a day. Intravenous urography showed no dilatation of pelvicalyceal systems or ureters. During the course of the next 4 months, the dose of baclofen had to be increased gradually to 820 microg/day in order to control the spasms. Investigations revealed disconnection of the tube from the pump. The patient decided to undergo explantation of the pump and discontinue intrathecal baclofen therapy altogether. Following removal of the pump, he was prescribed baclofen 20 mg four times a day and diazepam 5 mg twice a day. He continued penile sheath drainage with oxybutynin 2.5 mg twice a day. Although spasms were controlled with oral baclofen and diazepam, he started getting transient, mild headache during reflex voiding. After nearly 2 years, he developed unbearable and pounding headache while passing urine.

RESULTS

The dose of oxybutynin was increased to modified release formulation, 20 mg, once daily. He was prescribed modified release alfuzosin 10 mg once a day. Indwelling urethral catheter drainage was instituted. Intravenous urography showed dilation of left renal pelvis and calyces, and left ureter. After a fortnight, the dose of modified release oxybutynin was increased further to 25 mg once a day. After a month, he started performing self-catheterisation every 3 h and symptoms of autonomic dysreflexia subsided completely. A follow-up intravenous urography performed 6 months later, showed normal appearances of the left kidney.

CONCLUSION

Spinal cord injury patients, in whom intrathecal baclofen therapy is terminated, need close monitoring of their urological status. Medications, which are prescribed for neuropathic bladder, and the method of bladder drainage, may need suitable changes, as discontinuation of intrathecal baclofen therapy can result in reappearance of detrusor-sphincter dyssynergia in previously susceptible patients.

Pseudo-tumours of the urinary tract in patients with spinal cord injury/spina bifida

OBJECTIVE

To raise awareness of pseudo-tumours of urinary tract, as pseudo-tumours represent benign mass lesions simulating malignant neoplasms. Accurate diagnosis helps to avoid unnecessary surgery in spinal cord injury patients.

SETTING

Regional Spinal Injuries Centre, Southport, UK CASE REPORTS: Pseudo-tumour of kidney: A 58-year-old man with tetraplegia developed a right perirenal haematoma while taking warfarin; ultrasound and CT scanning showed no evidence of tumour in the right kidney. The haematoma was drained percutaneously. After 8 months, during investigation of a urine infection, ultrasound and CT scan revealed a space-occupying lesion in the mid-pole of the right kidney. CT-guided biopsy showed features suggestive of an organising haematoma; the lesion decreased in size over the next 13 months, thus supporting the diagnosis. Pseudo-tumour of urinary bladder: A frail, 34-year-old woman, who had spina bifida, marked spinal curvature and pelvic tilt, had been managing her neuropathic bladder with pads. She had recurrent vesical calculi and renal calculi. CT scan was performed, as CT would be the better means of evaluating the urinary tract in this patient with severe spinal deformity. CT scan showed a filling defect in the base of the bladder, and ultrasound revealed a sessile space-occupying lesion arising from the left bladder wall posteriorly. Flexible and, later, rigid cystoscopy and biopsy demonstrated necrotic slough and debris but no tumour. Ultrasound scan after 2 weeks showed a similar lesion, but ultrasound-guided biopsy was normal with nothing to explain the ultrasound appearances. A follow-up ultrasound scan about 7 weeks later again showed an echogenic mass, but the echogenic mass was seen to move from the left to the right side of the bladder on turning the patient, always maintaining a dependent position. The echogenic bladder mass thus represented a collection of debris, which had accumulated as a result of chronic retention of urine and physical immobility.

CONCLUSION

Recognising the true, non-neoplastic nature of these lesions enabled us to avoid unnecessary surgical procedures in these patients, who were at high risk of surgical complications because of severely compromised cardiac and respiratory function.

Flawed trial of micturition in cervical spinal cord injury patients: guidelines for trial of voiding in men with tetraplegia

STUDY DESIGN

A retrospective study.

OBJECTIVES

(1) To raise awareness of flawed trial of micturition (TOM) in male spinal cord injury (SCI) patients; and (2) to present guidelines for trial of voiding in male SCI patients.

SETTING

Regional Spinal Injuries Centre, Southport, UK.

METHODS

Trial of micturition in male SCI patients refers to discarding indwelling catheters and establishing them on balanced voiding with penile sheath drainage. We describe seven SCI patients, whose trial of micturition was flawed.

RESULTS

Two patients (C-6 and C-4 tetraplegia respectively) developed severe autonomic dysreflexia (headache, sweating, and increase in blood pressure) 2-3 h after removal of urethral catheter. A C-4 tetraplegic developed severe urinary infection after TOM. Four patients with tetraplegia started retaining increasing amounts of urine and developed urinary infections/autonomic dysreflexia/hydronephrosis 1-21 months after they were established on sheath drainage after TOM.

CONCLUSION

During TOM, patients with cervical SCI could develop autonomic dysreflexia, urinary infection, or hold progressively increasing volumes of residual urine. TOM should be guided by videourodynamics. SCI patients need alpha-blockers, and anticholinergics if voiding pressures are >40-50 cm H(2)O. If high urethral resistances are found, sphincterotomy and/or bladder neck incision will help the patients to void by triggering. SCI patients, who had undergone successful TOM, require meticulous follow-up including urodynamics. Intermittent catheterisation without adequate medications based on cystometrogram may be hazardous, and may result in upper tract damage. Facilities for supplementary catheterisation (three to four times a day) should be available in the community if a patient is unable to maintain complete, low-pressure, emptying of bladder.

Treatment of spasticity in a spinal cord-injured patient with intrathecal morphine due to intrathecal baclofen tolerance--a case report and review of literature

STUDY DESIGN

Case report.

OBJECTIVE

To report treatment of spasticity in a spinal cord-injured person with intrathecal morphine after the person developed tolerance to intrathecal baclofen.

METHOD

Spasticity in a 36-year-old man with T6 complete paraplegia was treated with increasing doses of intrathecal baclofen. When he developed tolerance to intrathecal baclofen, he was given continuous infusion of morphine intrathecally.

SETTING

Regional Spinal Injuries Centre, UK.

RESULTS

Spasticity was adequately controlled by intrathecal morphine.

CONCLUSION

In spinal cord-injured patients with severe spasticity, who become tolerant to intrathecal baclofen, treatment with intrathecal morphine may be useful.

Occlusion of left common iliac vein by a distended urinary bladder in a male with paraplegia due to spinal cord injury

STUDY DESIGN

A report of a male subject who sustained paraplegia at T-5 level due to spinal cord injury (SCI) 18 years ago, and in whom, occlusion of the left common iliac vein by a distended bladder was detected during a routine follow-up.

OBJECTIVES

To illustrate a rare complication of chronic distension of the urinary bladder viz occlusion of the left common iliac vein, which persisted even after providing adequate bladder drainage by intermittent catheterisation.

SETTING

Regional Spinal Injuries Centre, Southport, UK.

METHODS

As part of a routine follow-up, we performed intravenous urography by injecting 50 ml of Ultravist 300 in a vein over the dorsum of the left foot. Opacification of collateral veins in the pelvis was seen in the 5- and 10-min films, which suggested iliac venous occlusion. In order to confirm the diagnosis, contrast was injected intravenously in the left foot and venography was performed.

RESULTS

Venography revealed a distended left common iliac vein with contrast flowing into the right internal iliac vein through collateral veins in the pelvis; the right common iliac vein and inferior vena cava were patent. Duplex Doppler sonography showed compression of left common iliac vein by the posterior wall of a distended bladder with absence of blood flow through the compressed segment. Computerised tomography (CT) confirmed the diagnosis of extrinsic compression of the left common iliac vein against the promontory of sacrum by a distended bladder. CT excluded other causes for iliac vein occlusion.

CONCLUSION

In a male subject with SCI, chronic bladder distension produced occlusion of the left common iliac vein. Health professionals caring for individuals with SCI should be aware that long-standing bladder distension could cause pressure effects upon adjacent structures in the pelvis.

Bilateral extracorporeal shock wave lithotripsy in a spinal cord injury patient with a cardiac pacemaker

OBJECTIVES

To review the precautions to be observed before and during extracorporeal shock wave lithotripsy (ESWL) in spinal cord injury (SCI) patients with a cardiac pacemaker and the safety of bilateral ESWL performed on the same day.

DESIGN

A case report of bilateral ESWL in a SCI patient with a permanent cardiac pacemaker.

SETTING

The Regional Spinal Injuries Centre, Southport, the Lithotripsy Unit, the Royal Liverpool University Hospitals NHS Trust, Liverpool, and the Department of Cardiology, Manchester Royal Infirmary, Manchester, UK.

SUBJECT

A 43-year-old male sustained a T-4 fracture and developed paraplegia with a sensory level at T-2. During the post-injury period, he developed episodes of asystole requiring implantation of a dual chamber (DDD) permanent pacemaker. Twenty-one months later, he developed a right ureteric calculus with hydronephrosis. A radio-opaque shadow was seen in the left kidney with no hydronephrosis. During right ureteric stenting, the ureteric stone was pushed into the renal pelvis. 1,500 shock waves were delivered to this stone on the right side, followed by ESWL to the left intra-renal stone with 1250 shock waves.

RESULTS

The patient tolerated ESWL to both kidneys. The pacemaker was reprogrammed to a single chamber ventricular pacing mode at 30 beats per minute with a reduced sensitivity during lithotripsy. There were no untoward cardiac events during or after lithotripsy. The serum creatinine was 45 micromol/l before lithotripsy and 44 micromol/l two weeks after ESWL.

CONCLUSION

SCI patients with a cardiac pacemaker may be able to undergo extracorporeal shock wave lithotripsy following temporary reprogramming of the pacemaker. Bilateral, simultaneous ESWL is safe in the vast majority of patients provided that there is no risk of simultaneous ureteric obstruction by stone fragments. However, it should be remembered that a decrease in renal function could occur following bilateral ESWL of renal calculi.

Xanthogranulomatous funiculitis and epididymo-orchitis in a tetraplegic patient

STUDY DESIGN

A case report of xanthogranulomatous funiculitis and epididymo-orchitis. Xanthogranulomatous inflammation is an uncommon, non-neoplastic process characterised by destruction of tissue, which is replaced by a striking cellular infiltrate of lipid-laden macrophages.

CASE REPORT

A 21-year male sustained complete tetraplegia at C-6 level, after a fall in 1998. The neuropathic bladder was managed with an indwelling urethral catheter. He had many unsuccessful trials of micturition. Sixteen months after the cervical injury, he noticed swelling of the left side of the scrotum following removal of a blocked catheter. He was prescribed antibacterial therapy. Four weeks later, physical examination revealed a hard and irregular swelling encompassing the testis, epididymis and spermatic cord. The clinical diagnosis was epididymo-orchitis progressing to pyocele. Through a scrotal incision, the swollen testis, epididymis and diseased segment of the spermatic cord were removed en masse. Histopathology showed extensive areas of necrosis, with xanthogranulomatous inflammation in the spermatic cord and to a lesser extent in the testis/epididymis.

CONCLUSION

Repeated episodes of high-pressure urinary reflux along the vas deferens during dyssynergic voiding, and subsequent interstitial extravasation of urine together with chronic, low-grade, suppurative infection possibly led to development of xanthogranulomatous inflammation in the testis and the epididymis. Since tissue destruction is a feature of xanthogranulomatous inflammation, the definite and curative treatment is either complete (or, where applicable, partial) excision of the affected organ in most of the cases.

Field trial of efficacy of local compression immobilization first-aid technique in Russell's viper (Daboia russelii siamensis) bite patients

A field trial of efficacy of local compression immobilization first-aid technique in 42 Russell's viper bite cases was studied and only 19 were envenomed. Proper immobilization was carried out in 3/13 immobilized cases. The average time of application of the pad was 1.12 hours (range 5 minutes to 7 hours) and the total duration of the pad application was 3 hours 40 minutes (range 30 minutes to 9 hours). Venom levels measured at the hospital before and at 15 and 30 minutes after release of the pad (n=10) showed a rise of 5 to 30 ng/ml of venom following release. Movement of venom antigen was found to be retarded in all cases (n=9) whose venom levels were measured at 15 and 30 minutes with the pad in place. Sixteen out of 19 cases had systemic envenoming, indicating that pad or immobilization alone is not effective in delaying spread of venom. The incidence of local necrosis 3/42 (8%) following use of the pad was comparable to that of the systemic cases without the pad. No ill effects were observed following its application for as long as 9 hours. Local blackening seen in 4/36 (10%) cases was likely to be result of a local venom effect.

Delayed diaphragm recovery in 12 patients after high cervical spinal cord injury. A retrospective review of the diaphragm status of 107 patients ventilated after acute spinal cord injury

STUDY DESIGN

The functional outcome of the diaphragm after acute spinal cord injury was reviewed over a 16 year period for 107 patients who had required assisted ventilation in the acute phase.

OBJECTIVES

To quantify the incidence of recovery of diaphragm function which occurred beyond the period of acute oedema; to produce a time-related profile of this as a guide to clinicians considering phrenic nerve pacing; and to assess the value of phrenic nerve testing in predicting recovery.

SETTING

The Southport Regional Spinal Injuries Centre, Southport, England.

METHODS

Bilateral phrenic nerve and diaphragm integrity was assessed clinically, by spirometry, and by fluoroscopy without and with phrenic nerve stimulation.

RESULTS

Thirty-one per cent of all the ventilated patients (33 cases), with a level of injury between C1 and C4 (Scale A in ASIA Impairment Scale), had diaphragmatic paralysis at the time of respiratory failure. The subsequent diaphragm recovery which appeared in seven of these patients, between 40 and 393 days (mean 143), permitted weaning from ventilatory support at 93 to 430 days (mean 246) after the acute injury, with a vital capacity of over 15 ml kg(-1) at that stage. The diaphragm recovery in a further five patients, whose vital capacity remained below 10 ml kg(-1) and who could not be fully weaned, occurred significantly later, between 84 and 569 days (mean 290), P=0.053. Negative phrenic nerve tests were followed by weaning at a later interval in several cases. By contrast, one patient with an early positive phrenic stimulation test and subsequent diaphragm activity could not be weaned from the ventilator.

CONCLUSION

Twenty-one per cent of the patients with initial diaphragm paralysis were ultimately able to breathe independently after 4 and 14 months, whilst a further 15% had some diaphragm recovery. Phrenic nerve testing should be repeated at 3 monthly intervals for the first year after high tetraplegia.

A review of the readmissions of patients with tetraplegia to the Regional Spinal Injuries Centre, Southport, United Kingdom, between January 1994 and December 1995

Patients with chronic tetraplegia are prone to develop unique clinical problems which require readmission to specialised centres where the health professionals are trained specifically to diagnose, and treat the diseases afflicting this group of patients. An appraisal of the readmission pattern of tetraplegic patients will provide the necessary data for planning allocation of beds for treatment of chronic tetraplegic patients. Hospital records of patients with tetraplegia readmitted to the Regional Spinal Injuries Centre, Southport, UK between 1 January 1994 and 31 December 1995 were analyzed to find out the number of tetraplegic patients who required readmission, reasons for readmission, duration of hospital stay, and mortality among patients readmitted. During the 2-year period, 155 tetraplegic patients were readmitted and 44 of them (28.4%) required more than one readmission (total readmission episodes: 221); these patients occupied 4.5 beds which is equivalent to 11.5% of the total bed capacity of the spinal unit. Among the reasons for the readmissions, evaluation and care of urinary tract disorders topped the list with 96 readmission episodes (43.43%) involving 70 patients; the median hospital stay was 3 days, and 18 patients (26%) required more than one readmission during this period. One hospital bed was occupied by the tetraplegic patients requiring treatment/evaluation of urinary tract disorders. Assessment and treatment of cardio-respiratory diseases was the second most common reason for readmission with 51 readmission episodes pertaining to 27 patients having a median hospital stay of 6 days; 13 patients (48%) were readmitted more than once within this 2-year period. Treatment of cardio-respiratory diseases in chronic tetraplegic patients required 1.2 hospital beds yearly. Only five tetraplegic patients were readmitted for treatment of pressure sore(s); however they had a prolonged hospital stay (median duration: 101 days). Social reasons accounted for 13 readmission episodes concerning nine patients who stayed in the hospital for varying periods (median: 6.5 days; mean: 35 days). Four tetraplegic patients readmitted with acute chest infection expired. An 81 year-old tetraplegic died of myocardial infarction. Urinary sepsis, renal insufficiency, respiratory failure and intra-cerebral haemorrhage accounted for the demise of a 41 year-old tetraplegic patient following surgical removal of a large, impacted stone at the pelviureteric junction. A tetraplegic patient who was admitted with haematuria subsequently underwent cystectomy for squamous cell carcinoma of the urinary bladder; he developed secondaries and expired 5 months later. As more patients with high cervical spinal cord injury survive the initial period of trauma, and as the life expectancy of tetraplegic patients increases, it is likely that greater numbers of tetraplegic patients will be requiring readmission to spinal injuries centre. Although it may be possible to prevent some of the complications of spinal cord injury and hence the need for a readmission, progress in medicine and rehabilitation technology will create additional demands for readmissions of chronic tetraplegic patients in order to implement the newer therapeutic strategies. Thus a change in the pattern of readmission of chronic tetraplegic patients is likely to be the future trend and this should be taken into account while making plans for providing the optimum care to chronic tetraplegic patients.

Pathophysiology of autonomic dysreflexia: long-term treatment with terazosin in adult and paediatric spinal cord injury patients manifesting recurrent dysreflexic episodes

INTRODUCTION

Spinal cord injury (SCI) results in disruption of synaptic influences on the sympathetic preganglionic neurones. Remodelling of spinal cord circuits takes place in spinal neurones caudal to cord injury. There is an increased vascular alpha-adrenoceptor responsiveness, and peripheral afferent (bladder) stimulation in SCI subjects induces a marked noradrenaline spillover below the level of spinal lesion. These neurophysiological changes possibly contribute to the development of autonomic dysreflexia, a condition of sympathetic hyper-excitability that develops after cervical, or upper dorsal cord injury with resultant paroxysmal rise in arterial pressure, and provide the scientific basis for the use of terazosin, a once-a-day, selective alpha-one adrenergic blocking drug.

OBJECTIVES

The use of terazosin, a long-acting, alpha 1-selective blocking agent was investigated in SCI patients who developed recurrent symptoms of autonomic dysreflexia, eg headache, sweating flushing of the face together with an increase in the arterial pressure.

DESIGN

An open, prospective study of the efficacy of terazosin in controlling recurrent autonomic dysreflexia in traumatic tetraplegic/paraplegic patients manifesting clinical features of dysreflexia in the absence of an acute precipitating cause such as a blocked catheter.

SETTING

The initial assessment and treatment were carried out in the Spinal Injuries Centre. Subsequently, the patients were followed-up in the community. They were monitored by telephonic interviews, follow-up visits by the patients to the hospital, and home-visits by the staff of the spinal unit.

SUBJECTS

Eighteen adults with tetraplegia (female: 1; male: 17), three children with ventilator-dependent tetraplegia and three adult male patients with paraplegia who exhibited recurrent features of autonomic dysreflexia in the absence of an acute predisposing factor for dysreflexia eg performance of an invasive procedure such as cystoscopy, digital evacuation of bowels, or acute urinary retention, were enrolled in this study.

INTERVENTION

After discussion with the patients and their carers, terazosin was prescribed with a starting dose of 1 mg in an adult and 0.5 mg in a child administered nocte. The patients were observed for (1) drug-induced hypotension; (2) clinical symptoms due to side effects of terazosin; and (3) continued occurrence of dysreflexic symptoms. Step-wise increments of the dose of terazosin (1 mg in case of adults, and 0.5 mg in a child) was carried out at intervals of 3-4 days, if a patient continued to develop dysreflexia but did not manifest any serious side effect.

OUTCOME MEASURES

Complete subsidence of dysreflexic symptoms, or development of an adverse event necessitating termination of the terazosin therapy was the clinical end point.

RESULTS

The dysreflexic symptoms subsided completely with the terazosin therapy in all the patients. The twenty-one adult patients required a dose varying from 1-10 mg, whereas the paediatric patients required only 1-2 mg of terazosin. The side effects of postural hypotension and drowsiness were transient, and mild. One tetraplegic patient developed persistent dizziness and therefore, the drug therapy was discontinued.

CONCLUSION

In 21 adult and three paediatric spinal cord injury patients manifesting recurrent episodes of autonomic dysreflexia in the absence of an acute predisposing cause, the use of terazosin, a once-a-day, specific alpha-one blocker resulted in complete subsidence of the dysreflexic symptoms. However, one tetraplegic patient required termination of terazosin therapy because of persistent dizziness.

The use of personal protective measures in control of malaria in a defined community

Malaria is one of the main health problems in the non-immune immigrant workers and army personnel of the malaria endemic areas in Myanmar. Due to changes in the vector bionomics and multiresistant strains of P. falciparum, chemoprophylaxis alone is not an effective means of control of malaria in them. So it is envisaged that the combined used of personal protective measures (deltamethrin impregnated bed-nets, scalves and hand-bands) and the chemoprophylaxis will be an effective means of control of malaria in the define group of people. The study also intended to find out the side effects of the deltamethrin and feasibility and acceptability of methods by the users. The study was conducted in Theini Township, Northern Shan State, from March to November 1993. The study population consisted of all ages of both sexes 554 and 440 persons in the test and control groups respectively. At the initial phase of the study, malaria infected persons from both the groups were treated. The experimental group received personal protective measures with impregnation of bed-nets using 25 mg ai/m2 of deltamethrin at 4 monthly intervals and the scarves and hand-bands at twice the concentration of the insecticides at monthly intervals. Chemoprophylaxis was given to both the groups at weekly intervals using age adjusted dosage of Pyrixine tablet (sulfadoxine-pyrimethamine). The parasitological, entomological, and epidemiological indices were collected at two month intervals in both the groups. The study clearly showed the impact of personal protective measures and chemoprophylaxis on malaria infection in the studied subjects. During the study period, the out patient malaria cases of the test group was 6% to 11.2% and that of the control group was 12% to 21.6% in Theini Hospital. The reinfection rate of the test group (0.9 to 4.7%) was also significantly lower than the control group (6.1 to 14.3%) from July to November. Acceptance of the treated bed-nets, scarves and hand-bands was high and good compliance was found in the follow up. The results of the study clearly showed that malaria can be controlled effectively in the defined group of persons for a malaria transmission season by using chemoprophylaxis and personal protective measures.
