Primary Endometriosis of Umbilical Scar: Case Report and Review of Literature

We report a case of umbilical endometriosis and review the literature about the finding. The patient was a 39-year-old woman who presented with 6 months of umbilical bleeding and pain during the first day of her period. A soft tissue ultrasound scan showed 2 superficial solid masses within the periumbilical subcutaneous adipose tissue, suggestive for ectopic endometriosis localization. We decided to remove the umbilical nodules, excising 1 cm of the surrounding tissue. Reports in the literature indicate cases of umbilical endometriosis in about 0.5%-1% of women with endometriosis.

An enriched multimedia eBook application to facilitate learning of anatomy

This pilot study compared the use of an enriched multimedia eBook with traditional methods for teaching the gross anatomy of the heart and great vessels. Seventy-one first-year students from an Australian medical school participated in the study. Students' abilities were examined by pretest, intervention, and post-test measurements. Perceptions and attitudes toward eBook technology were examined by survey questions. Results indicated a strongly positive user experience coupled with increased marks; however, there were no statistically significant results for the eBook method of delivery alone outperforming the traditional anatomy practical session. Results did show a statistically significant difference in the final marks achieved based on the sequencing of the learning modalities. With initial interaction with the multimedia content followed by active experimentation in the anatomy lab, students' performance was improved in the final test. Obtained data support the role of eBook technology in modern anatomy curriculum being a useful adjunct to traditional methods. Further study is needed to investigate the importance of sequencing of teaching interventions.

The Effect of Individual Reminiscence Therapy on Self-Esteem and Depression Among Institutionalized Elderly in India

Nurses often elicit patients’ stories as a means to an end—for example, getting to know patients better and providing better care or treatments. However, the act of listening in itself can be therapeutic. Through the use of reminiscence therapy (RT), eliciting stories from elderly residents of a nursing home in India improved their sense of well-being. This article describes a study of the use of RT and presents one resident’s story.

JERM model of care: an in-principle model for dental health policy

Oral diseases are the most prevalent conditions in the community. Their economic burden is high and their impact on quality of life is profound. There is an increasing body of evidence indicating that oral diseases have wider implications beyond the confines of the mouth. The importance of oral health has not been unnoticed by the government. The Commonwealth (Federal) government under the Howard-led Coalition in 2004 had broken tradition by placing dentistry in its universal health insurance scheme, Medicare. Known as the Chronic Disease Dental Scheme (CDDS), the program aimed to manage patients with chronic conditions as part of the Enhanced Primary Care initiative. This scheme was a landmark policy for several reasons. Besides being the first major dental policy under Medicare, the program proved to be the most expensive and controversial. Unfortunately, cost containment and problems with service provision led to its cessation in 2012 by the Gillard Labor Government. Despite being seen as a failure, the CDDS provided a unique opportunity to assess national policy in practice. By analysing the policy-relevant effects of the CDDS, important lessons can be learnt for policy development. This paper discusses these lessons and has formulated a set of principles recommended for effective oral health policy. The JERM model represents the principles of a justified, economical and research-based model of care.

Comparing performance of Tabriz obstetrics and gynaecology hospitals managed as autonomous and budgetary units using Pabon Lasso method

BACKGROUND

Considering governmental scrutiny and financial constraints in medicine, the need for improved performance, which can provide acceptable care for medical consumers, leads to the conduct of new managerial methods to improve effectiveness.

AIMS

This study aimed to compare performance indicators of obstetrics and gynaecology teaching hospitals in Tabriz.

METHOD

A longitudinal, retrospective study was conducted to compare performance indexes of Tabriz obstetrics and gynaecology teaching hospitals during 2010-2012. Al-Zahra is Tabriz's central teaching hospital in obstetrics and gynaecology that is authorised under a board of trustees as an autonomous hospital and Taleghani hospital is managed under centralised administration. Study variables included: Average Length of Stay (ALOS), Bed Occupancy Rate (BOR), and Bed Turnover Ratio (BTR). The data was extracted via the Hospital Information Systems (HIS) within the hospitals' admission and discharge units. Pabon Lasso model was used to assess hospital performance. Data was analysed and graphs were plotted using the SPSS-17 software package.

RESULTS

According to study findings, overall ALOS in Al-Zahra hospital is 3.15 (2.15) days (1.88 (0.97) days for prenatal wards and 6.13 (0.97) days for neonatal wards) and ALOS in Taleghani Hospital is 3.37 (3.09) days (1.74 (0.14) days for perinatal wards and 5.96 (3.55) days for neonatal wards). In this regard, Al-Zahra hospital holds the maximum BOR with 86.92 per cent and the minimum BOR was attributed to Taleghani hospital at 68.44 per cent (P<0.001). Study findings indicate that BOR in neonatal wards is greater than prenatal wards. On the other hand, BOR in Al-Zahra is greater than Taleghani (P<0.001), whereas BOR trend shows an increasing pattern in both hospitals.

CONCLUSION

Results of this study showed that the performance of Al- Zahra Hospital is better than Taleghani Hospital. These two hospitals are similar in different aspects except Al-Zahra is under a board of trustees and Taleghani is not. We should also consider that Al-Zahra Hospital has more facilities than Taleghani.

Same admissions tools, different outcomes: a critical perspective on predictive validity in three undergraduate medical schools

BACKGROUND

Admission to medical school is one of the most highly competitive entry points in higher education. Considerable investment is made by universities to develop selection processes that aim to identify the most appropriate candidates for their medical programs. This paper explores data from three undergraduate medical schools to offer a critical perspective of predictive validity in medical admissions.

METHODS

This study examined 650 undergraduate medical students from three Australian universities as they progressed through the initial years of medical school (accounting for approximately 25 per cent of all commencing undergraduate medical students in Australia in 2006 and 2007). Admissions criteria (aptitude test score based on UMAT, school result and interview score) were correlated with GPA over four years of study. Standard regression of each of the three admissions variables on GPA, for each institution at each year level was also conducted.

RESULTS

Overall, the data found positive correlations between performance in medical school, school achievement and UMAT, but not interview. However, there were substantial differences between schools, across year levels, and within sections of UMAT exposed. Despite this, each admission variable was shown to add towards explaining course performance, net of other variables.

CONCLUSION

The findings suggest the strength of multiple admissions tools in predicting outcomes of medical students. However, they also highlight the large differences in outcomes achieved by different schools, thus emphasising the pitfalls of generalising results from predictive validity studies without recognising the diverse ways in which they are designed and the variation in the institutional contexts in which they are administered. The assumption that high-positive correlations are desirable (or even expected) in these studies is also problematised.

Over-the-counter medication patterns in households in Sharjah, United Arab Emirates

Background

Self-medication and acquisition of over-the-counter (OTC) medications are emerging community health issues. Besides being a cheap alternative for treating common illnesses, the behavior entails serious ramifications, such as medication wastage, increasing pathogen resistance, and adverse drug reactions. The present study was conducted to explore the extent of OTC medications in households in Sharjah, United Arab Emirates (UAE), including native UAE and expatriate families.

Methods

The study employed a population-based, cross-sectional, analytical study design. The study population included native and expatriate households residing in the Emirate of Sharjah, UAE. The snowball sampling technique was used, and the sample included a total of 335 households.

Results

Expatriate households acquired more OTC medications than did native households (adjusted odds ratio [aOR]=1.7). The demographic determinants for expatriate households were number of family members (aOR=1.6), age of children in the family (aOR=1.8), and annual income (aOR=0.5). Expatriate households purchased more OTC medication practices than did native households (aOR=2.2). In the statistical sense, expatriate household practices were buying medication upon relatives’ advice (aOR=0.3), storage condition of medication (aOR=2.4), and disposal of expired medication (aOR=0.6). The highest percentages of OTC medications in native and expatriate households were those related to gastric and ear, nose, and throat illnesses.

Conclusion

The presence of OTC medications in expatriate households was two-fold more common than in native households in Sharjah, UAE. There were significant associations for behaviors related to the reasons why OTC medications were purchased and stored within the household for both native and expatriate families.

The association between stressful life events and depressive symptoms among Cypriot university students: a cross-sectional descriptive correlational study

Background

Previous findings suggest that stressful life events have a causal relationship with depressive symptoms. However, to date little is known concerning the contribution of the number and severity of recent stressful life events on the prevalence of depressive symptoms among university students. The aim of this study was to investigate the prevalence of depressive symptoms and its association with the number and the severity of self-reported stressful life events among university students in Cyprus.

Methods

A descriptive correlational design with cross sectional comparison was used. The CES-D scale was applied for the assessment of depressive symptoms and the LESS instrument for stressful life events. Both scales were completed anonymously and voluntarily by 1.500 students (response rate 85%).

Results

The prevalence of mild to moderate depressive symptoms [CES-D score between 16 and 21] and of clinically significant depressive symptoms [CES-D score ≥ 22] were 18.8% and 25.3% respectively. There were statistically significant differences in clinically significant depressive symptoms by gender, with higher rates among women (x² = 8.53, df = 1, p = 0.003). Higher scores on the LESS scale were associated with more frequent reports of clinical depressive symptoms (x² = 70.63, df = 4, p < 0.001). Similarly, an association was found between the number of life events and clinical depressive symptoms (x² = 40.06, df = 4, p < 0.001). Logistic regression analysis after adjusting for socio-demographic characteristics confirmed that the responders who reported a high number (n = 12–21) of stressful life events during the previous year (OR = 2.64 95% CI: 1.02, 6.83) and a severe degree of stress due to these events (total LESS score > 351, OR = 3.03 95% CI: 1.66, 5.39) were more likely to manifest clinical depressive symptoms.

Conclusions

The high frequency of occurrence of depressive symptoms among Cypriot university students, as well as the strong association with stressful life events, highlights the need for psychological empowerment strategies towards students by institutional counseling services.

Diagnostic value of whole-body diffusion-weighted magnetic resonance imaging for detection of primary and metastatic malignancies: a meta-analysis

PURPOSE

To perform a meta-analysis to evaluate the diagnostic performance of whole-body diffusion-weighted magnetic resonance imaging (WB-DWI) technique in detection of primary and metastatic malignancies compared with that of whole-body positron emission tomography/computed tomography (WB-PET/CT).

MATERIALS AND METHODS

Search Pubmed, MEDLINE, EMBASE and Cochrane Library database from January 1984 to July 2013 for studies comparing WB-DWI with WB-PET/CT for detection of primary and metastatic malignancies. Methodological quality was assessed by the quality assessment of diagnostic studies (QUADAS) instrument. Sensitivities, specificities, predictive values, diagnostic odds ratio (DOR) and areas under the summary receiver operator characteristic curve (AUC) were calculated. Potential threshold effect, heterogeneity and publication bias were investigated.

RESULT

Thirteen eligible studies were included, with a total of 1067 patients. There was no significant threshold effect. WB-DWI had a similar AUC (0.966 (95% CI, 0.940-0.992) versus 0.984 (95% CI, 0.965-0.999)) with WB-PET/CT. No significant difference was detected between AUC of WB-DWI and WB-PET/CT. WB-DWI had a pooled sensitivity of 0.897 (95% CI, 0.876-0.916) and a pooled specificity of 0.954 (95% CI, 0.944-0.962). WB-PET/CT had a pooled sensitivity of 0.895 (95% CI, 0.865-0.920) and a pooled specificity of 0.975 (95% CI, 0.966-0.981). Heterogeneity was found to stem primarily from data type (per lesion versus per patient), MR sequence (DWIBS only and DWIBS with other sequence), and primary lesion type (single type and multiple type). The Deeks's funnel plots suggested the absence of publication bias.

CONCLUSION

WB-DWI has similar, good diagnostic performance for the detection of primary and metastatic malignancies compared with WB-PET/CT. DWIBS with other MR sequences could further improve the diagnostic performance. More high-quality studies regarding comparison of WB-DWI and WB-PET/CT and combination of them in detecting malignancies are still needed to be conducted.

Incidence of Chronic Laryngitis

Objectives:

We describe the incidence of chronic laryngitis (CL) and identify the most common presenting symptoms and initial treatments used.

Methods:

We retrospectively identified patients with a diagnosis of CL who were seen among a primary care cohort at an urban academic medical center from 2009 to 2010. The incidence of CL was calculated. Symptoms, first-visit treatment, smoking, and demographics were recorded.

Results:

Of a population of 40,317 people, 280 received a new diagnosis of CL over a 2-year period, representing a yearly incidence of 3.47 cases per 1,000 people. The subjects consisted of 160 women and 120 men. Race was recorded as black (126), Hispanic (47), white (68), or other (39). The mean age was 52.9 years (range, 20 to 90 years). The initial therapies included proton pump inhibitors (79%), voice therapy (17%), nasal steroid (13%), antihistamine (4%), amitriptyline (4%), other (17%), and none (11%). The most common symptoms were dysphonia (53%), pain/soreness (45%), globus sensation (40%), cough (33%), excessive throat clearing (28%), and dysphagia (32%). An otolaryngologist saw 93% of the cases.

Conclusions:

The yearly CL incidence was 3.47 per 1,000 people. Up to 21% of the population may develop CL in their lifetime. Most of the patients in this cohort were referred to otolaryngologists, and the majority were treated with proton pump inhibitors. Dysphonia, globus sensation, and pain were the most common symptoms. Population surveys could be used to define undiagnosed disease and the overall prevalence of CL.

Acute adverse events from over-the-counter Chinese herbal medicines: a population-based survey of Hong Kong Chinese

Background

Although over-the-counter traditional Chinese herbal medicine (COTC) is commonly used to treat everyday illness in many parts of the world, no population-based study has been done to examine the prevalence and factors associated with COTC-related adverse events.

Methods

A cross-sectional telephone survey was conducted among Hong Kong Chinese adults in 2011 (n = 1100) with informed verbal consent. Stepwise logistic regression of demographic, attitudinal and behavioral variables was used to determine factors associated with past-year adverse events.

Results

Of study respondents, 71.7% (789/1100) reported past-year COTC use and 2.3% (25/1100) reported at least one COTC-related adverse event in the past year. Of the 27 adverse events cases reported among COTC users, the most common were allergic reactions (n = 11) dizziness (n = 5), and gastro-intestinal problems (n = 4). Pills/capsules were the dosage form that caused the highest proportion of adverse events (n = 10), followed by plasters (n = 7), creams/ointments (n = 5), and ingestible powders (n = 2).

Although COTC users reporting adverse events were more likely to report greater practices to avoid adverse events (OR = 6.47; 95% CI: 1.38-30.3); they were also more likely to possess lower education levels (OR = 9.64, 95% CI: 2.20-42.3) and to have received COTC information from non-reliable, mass-media information sources such as magazines (OR = 3.32; 95% CI: 1.01-8.50) or television (OR = 2.93; 95% CI: 1.03-10.7). Package labels were also felt to be unclear by 42.9% of COTC users. A large proportion of COTC users demonstrated low levels of COTC-related knowledge, while the main impediment to greater information-seeking was the belief that reliable COTC information is not obtainable from Western health professionals.

Conclusions

Despite global movements toward more stringent complementary medicine regulation, the limited accessibility of reliable information and widespread misperceptions among consumers present major challenges for the safe use of complementary medicine.

A review of factors that influence individual compliance with mass drug administration for elimination of lymphatic filariasis

Background

The success of programs to eliminate lymphatic filariasis (LF) depends in large part on their ability to achieve and sustain high levels of compliance with mass drug administration (MDA). This paper reports results from a comprehensive review of factors that affect compliance with MDA.

Methodology/Principal Findings

Papers published between 2000 and 2012 were considered, and 79 publications were included in the final dataset for analysis after two rounds of selection. While results varied in different settings, some common features were associated with successful programs and with compliance by individuals. Training and motivation of drug distributors is critically important, because these people directly interact with target populations, and their actions can affect MDA compliance decisions by families and individuals. Other important programmatic issues include thorough preparation of personnel, supplies, and logistics for implementation and preparation of the population for MDA. Demographic factors (age, sex, income level, and area of residence) are often associated with compliance by individuals, but compliance decisions are also affected by perceptions of the potential benefits of participation versus the risk of adverse events. Trust and information can sometimes offset fear of the unknown. While no single formula can ensure success MDA in all settings, five key ingredients were identified: engender trust, tailor programs to local conditions, take actions to minimize the impact of adverse events, promote the broader benefits of the MDA program, and directly address the issue of systematic non-compliance, which harms communities by prolonging their exposure to LF.

Conclusions/Significance

This review has identified factors that promote coverage and compliance with MDA for LF elimination across countries. This information may be helpful for explaining results that do not meet expectations and for developing remedies for ailing MDA programs. Our review has also identified gaps in understanding and suggested priority areas for further research.

Lymphatic filariasis (LF, also known as “elephantiasis”) is a deforming and disabling disease that is caused by roundworm parasites that are transmitted by mosquitoes. The Global Programme to Eliminate Lymphatic Filariasis is the largest public health intervention program attempted to date based on mass drug administration (MDA). MDA does not cure filarial infections, but it can reduce or interrupt transmission of new infections by clearing larval parasites from human blood so that they are not available for mosquitoes. High levels of participation are required for this strategy to work; guidelines from the World Health Organization call for at least 65% of the eligible population to take the medications annually for four to six years. MDA presents logistical challenges that require cooperation between donors, health ministries, and communities. The success of MDA depends on coverage (drug delivery) and compliance (people ingesting antifilarial drugs), which depends on individual interactions between drug distributors and the people who live in LF-endemic areas. This paper focuses on this last step of implementation with a comprehensive review of published and unpublished information on factors that affect compliance with MDA at the level of the individual. We have also provided an outline of current gaps in understanding and recommendations for further research.

Role of exercise in the management of diabetes mellitus: the global scenario

Background

Exercise training programs have emerged as a useful therapeutic regimen for the management of type 2 diabetes mellitus (T2DM). Majority of the Western studies highlighted the effective role of exercise in T2DM. Therefore, the main aim was to focus on the extent, type of exercise and its clinical significance in T2DM in order to educate the clinicians from developing countries, especially in Asians.

Methods

Pubmed, Science Direct, Scopus, ISI Web of Knowledge and Google scholar were searched using the terms “type 2 diabetes mellitus,” “type 2 DM,” “exercise,” and/or “physical activity,” and “type 2 diabetes mellitus with exercise.” Only clinical or human studies published in English language between 2000 and 2012 were included. Certain criteria were assigned to achieve appropriate results.

Results

Twenty five studies met the selected criteria. The majority of the studies were randomized controlled trial study design (65%). Most of the aerobic exercise based studies showed a beneficial effect in T2DM. Resistance exercise also proved to have positive effect on T2DM patients. Minimal studies related to other types of exercises such as yoga classes, joba riding and endurance-type exercise were found. On the other hand, United States of America (USA) showed strong interest of exercise management towards T2DM.

Conclusion

Aerobic exercise is more common in clinical practice compared to resistance exercise in managing T2DM. Treatment of T2DM with exercise training showed promising role in USA. A large number of researches are mandatory in the developing countries for incorporating exercise in the effective management of T2DM.

Accuracy of internet images of glenoid labral injuries

INTRODUCTION

The internet is a convenient source of health information used widely by patients and doctors. Previous studies have found that the written information provided was often inaccurate. There is no literature regarding the accuracy of medical images on the internet. The aim of this study was to assess the accuracy of internet images of injuries to the glenoid labrum following shoulder dislocation.

METHODS

The Google and Bing search engines were used to find images of Bankart, Perthes and anterior labroligamentous periosteal sleeve avulsion (ALPSA) lesions. Three independent reviewers assessed the accuracy of image labelling.

RESULTS

Of images labelled 'Bankart lesion', 30% (9/30) were incorrect while 'Perthes lesion' images were incorrect in 15% of cases (9/60) and 4% of 'ALPSA lesion' images were incorrect (2/46). There was good interobserver reliability (kappa = 0.81). Labelling accuracy was better on educational sites than on commercial sites (6% vs 25% inaccurate, p=0.0013).

CONCLUSIONS

Caution is recommended when interpreting non-peer reviewed images on the internet.

Assessment and revision of clinical pharmacy practice internet web sites

BACKGROUND

Health care professionals, trainees, and patients use the Internet extensively. Editable Web sites may contain inaccurate, incomplete, and/or outdated information that may mislead the public's perception of the topic.

OBJECTIVE

To evaluate the editable, online descriptions of clinical pharmacy and pharmacist and attempt to improve their accuracy.

METHODS

The authors identified key areas within clinical pharmacy to evaluate for accuracy and appropriateness on the Internet. Current descriptions that were reviewed on public domain Web sites included: (1) clinical pharmacy and the clinical pharmacist, (2) pharmacy education, (3) clinical pharmacy and development and provision for reimbursement, (4) clinical pharmacists and advanced specialty certifications/training opportunities, (5) pharmacists and advocacy, and (6) clinical pharmacists and interdisciplinary/interprofessional content. The authors assessed each content area to determine accuracy and prioritized the need for updating, when applicable, to achieve consistency in descriptions and relevancy. The authors found that Wikipedia, a public domain that allows users to update, was consistently the most common Web site produced in search results.

RESULTS

The authors' evaluation resulted in the creation or revision of 14 Wikipedia Web pages. However, rejection of 3 proposed newly created Web pages affected the authors' ability to address identified content areas with deficiencies and/or inaccuracies.

CONCLUSIONS

Through assessing and updating editable Web sites, the authors strengthened the online representation of clinical pharmacy in a clear, cohesive, and accurate manner. However, ongoing assessments of the Internet are continually needed to ensure accuracy and appropriateness.

What prescribing means to pharmacists: a qualitative exploration of practising pharmacists in Alberta

Objective

In 2007 Alberta, Canada, became the first North American jurisdiction to adopt prescribing legislation for pharmacists. In light of these legislative changes and expanded scope of pharmacy practice, we evaluated what ‘prescribing’ means to pharmacists in Alberta and the application of prescribing in pharmacy practice.

Methods

We invited pharmacists to participate in semi-structured telephone interviews using closed and open-ended questions. Pharmacists working in community, hospital or other settings were selected using a mix of random and purposive sampling. Interviews were audiorecorded and transcribed, and data were entered into nVIVO 9 software. Transcriptions were analysed by two investigators using an interpretive description approach to identify themes.

Key findings

Thirty-eight pharmacists were interviewed, of whom 13 had additional (independent) prescribing authorization. Prescribing had a wide breadth of meaning to the pharmacists in our study, which included writing a new prescription and extending an existing prescription, as well as advising on non-prescription medications. Pharmacists described prescribing in terms of the physical act of writing the prescription and as part of the patient care process as well as the legislated definition of pharmacist prescribing. The sense of increased responsibility associated with prescribing was noted by many pharmacists.

Conclusion

Prescribing had diverse meanings to pharmacists in our study, and appeared to be context-specific. Understanding the meaning prescribing holds for individual pharmacists is important to explore whether pharmacist’s definition of this expanded scope has shaped pharmacists’ enactment of prescribing practice.

Hypertension and prehypertension among adolescents in secondary schools in Enugu, South East Nigeria

BACKGROUND

Hypertension is a prevalent cardiovascular disease risk factor among blacks and adolescent hypertension can progress into adulthood.

OBJECTIVE

To determine the prevalence of hypertension and prehypertension among secondary school adolescents in Enugu South East Nigeria.

METHODOLOGY

A study of 2694 adolescents aged 10-18 years in Enugu metropolis was carried out. Socio-demographic profile anthropometric and blood pressure readings were obtained. Derived measurements such as Prehypertension, hypertension and BMI were obtained.

RESULTS

The results showed that the mean systolic blood pressure and diastolic blood pressure for males were 106.66+ 11.80 mmHg and 70.25 + 7.34 mmHg respectively. The mean SBP and DBP for females were 109.83+ 11.66 mmHg and 72.23 + 8.26 mmHg respectively (p < 0.01). Blood pressure was found to increase with age. Prevalence of hypertension and prehypertension was 5.4% and 17.3% respectively with a higher rate in females (6.9%) than males (3.8%). Prevalence of prehypertension among males and females were 14.3% and 20.1% respectively. The prevalence of obesity was 1.9%.

CONCLUSION

Modifiable risk factors exist among adolescents. Early lifestyle modification and a strengthened school health are recommended.

Pharmacokinetic behavior presents drug therapy challenges

There are conditions that cause a substantial change in drug clearance to such a degree that how a specific drug is managed to optimize drug response and minimize drug toxicity presents a challenge. This review will focus on recent literature (within the past 5 years) that evaluates pathophysiologic and genetic conditions and drug interactions which can change drug clearance to the magnitude that response is affected. Situations discussed that cause an increase in drug clearance will include: augmented renal clearance in critically ill patients; ultrafast drug metabolism caused by gene duplication; and enzyme induction interactions caused by rifampin. Situations discussed that result in a reduction in clearance will include: multiple organ failure in critically ill, patients with non-functioning CYP2D6 and CYP2C8/9 alleles, and CYP3A4 drug interactions with erythromycin and clarithromycin. In each case evaluated clearance is changed to the magnitude such that managing drug therapy can be difficult.

Adjuvant system AS02V enhances humoral and cellular immune responses to pneumococcal protein PhtD vaccine in healthy young and older adults: randomised, controlled trials

BACKGROUND

The protection elicited by polysaccharide pneumococcal vaccines against community-acquired pneumonia in older adults remains debatable. Alternative vaccine targets include well-conserved pneumococcal protein antigens, such as pneumococcal histidine triad protein D (PhtD).

OBJECTIVE

To evaluate humoral and cellular immune responses and safety/reactogenicity following immunisation with PhtD vaccine with or without adjuvant (alum or AS02V) in older (≥65 years) and young (18-45 years) healthy adults.

METHODS

Two phase I/II, single-blind, parallel-group studies were conducted in 150 older and 147 young adults. Participants were randomised to receive 2 doses (months 0 and 2) of PhtD 30 μg, PhtD 10 μg plus alum, PhtD 30 μg plus alum, PhtD 10 μg plus AS02V or PhtD 30 μg plus AS02V, or the 23-valent polysaccharide pneumococcal vaccine (23PPV) at month 0 with placebo (saline solution) at month 2. Safety/reactogenicity was assessed. PhtD-specific antibody, T cell and memory B cell responses were evaluated.

RESULTS

Solicited adverse events were more common in young participants and with adjuvanted vaccines. No vaccine-related serious adverse events were reported. Although anti-PhtD geometric mean antibody concentrations (GMCs) were consistently lower in the older adult cohort than in young adults, GMCs in the older cohort following PhtD 30 μg plus AS02V were comparable to those induced by plain PhtD or PhtD 30 μg plus alum in the young cohort. Compared with alum adjuvant, AS02V adjuvant system was associated with an increased frequency of PhtD-specific CD4 cells in both cohorts and a significantly higher specific memory B cell response in the older cohort, similar to responses obtained in the young cohort.

CONCLUSION

The improved immune response to PhtD vaccine containing the AS02V adjuvant system in comparison to alum suggests that the reduced immune response to vaccines in older adults can be partially restored to the response level observed in young adults. ClinicalTrials.gov identifiers: NCT00307528/NCT01767402.

Three-dimensional reconstruction of human vocal folds and standard laryngeal cartilages using computed tomography scan data

Three-dimensional (3D) computer models of the human larynx are useful tools for research and for eventual clinical applications. Recently, computed tomography (CT) scanning and magnetic resonance imaging (MRI) have been used to recreate realistic models of human larynx. In the present study, CT images were used to create computer models of vocal folds, vocal tract, and laryngeal cartilages, and the procedure to create solid models are explained in details. Vocal fold and vocal tract 3D models of healthy and postsurgery larynges during phonation and respiration were created and morphometric parameters were quantified. The laryngeal framework of eight patients was also reconstructed from CT scan images. For each cartilage, morphometric landmarks were measured on the basis of their importance for biomechanical modeling. A quantitative comparison was made between measured values from the reconstructions and those from human excised larynges in literature. The good agreement between these measurements supports the accuracy of CT scan-based 3D models. Generic standard models of the laryngeal framework were created using known features in modeling softwares. They were created based on the morphometric landmark dimensions previously defined, preserving all biomechanically important dimensions. These models are accessible, subject independent, easy to use for computational simulations, and make the comparisons between different studies possible.

Generic medicines: an evaluation of the accuracy and accessibility of information available on the Internet

Background

Internationally, generic medicines are increasingly seen as a key strategy to reduce healthcare expenditure, therefore awareness and knowledge transfer regarding generic medicines are valid areas of research. Although the Internet is a frequently used source of medical information, the accuracy of material found online is variable. The aim of this study was to evaluate information provided on the Internet regarding generic medicines in terms of quality of information and readability.

Methods

Internet searches for information regarding generic medicine were completed, with a pre-defined search term, using the Google search engine, in five English-speaking geographical regions (US, UK, Ireland, Canada and Australia). Search results likely to be looked at by a searcher were collated and assessed for the quality of generic medicine-related information in the websites, using a novel customised Website Quality Assessment (WQA) tool; and for readability, using existing methods. The reproducibility of the tools between two independent reviewers was evaluated and correlations between WQA score, readability statistics and Google search engine results page ranking were assessed.

Results

Wikipedia was the highest-ranking search result in 100% of searches performed. Considerable variability of search results returned between different geographical regions was observed, including that websites identified in the Australian search generated the highest number of country specific websites; searches performed using computers with Irish, British, American and Canadian IP addresses appear to be more similar to each other than the google.com search performed in Australia; and the Canadian google.ca results show a notable difference from any of the other searches. Of the 24 websites assessed, none scored a perfect WQA score. Notably, strong correlation was seen between WQA and readability scores and ranking on google.com search results.

Conclusions

This novel evaluation of websites providing information on generic medicines showed that, of the websites likely to be seen by a searcher, none demonstrated a combination of scoring highly on quality of information (as evinced by WQA score) and readability. Therefore, there is a gap in online knowledge provision on this topic which, if filled by a website designed using the WQA tool developed in this study, has an improved likelihood of ranking highly in google.com search results.

The Australian experience without formal guidelines: the projected cost impact of hospitalisations for surgical removal of impacted teeth through to 2020

In Britain there was a reduction in hospitalisations for removal of impacted teeth (in particular third molars) following the introduction of evidence-based guidelines. However, the guideline approach has not been as successful in other countries, even those with a significant historical connection. In Australia, hospitalisation (ie to undergo treatment under general anaesthesia) for the removal of impacted teeth constitutes about two thirds of all oral health-related conditions requiring treatment under general anaesthesia.

Aetiological agents of ventilator-associated pneumonia and its resistance pattern - a threat for treatment

BACKGROUND

Ventilator-associated pneumonia (VAP) is a common type of nosocomial pneumonia encountered in intensive care units. There are several aetiological agents which make treatment challenging. Improper antibiotic treatment of ventilated patients may lead to the emergence of multidrug resistant (MDR) pathogens.

METHOD

A prospective study was performed over a period of 20 months. Our study had two arms: the first, 'Incidence and risk factors of VAP in a tertiary care hospital' was the subject of an earlier publication; we therefore present the second investigative arm in this work. The aetiological agents of patients on mechanical ventilation (MV) were identified by standard bacteriological method. The susceptibility pattern was evaluated by Kirby-Bauer disc diffusion method. Extended spectrum beta lactamase (ESBL) testing was performed by combination disc method, and metallo-beta lactamase (MBL) testing was performed by EDTA disk synergy test (EDS).

RESULTS

Late-onset VAP was associated with Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli, while early-onset VAP was commonly caused by members of Enterobacteriaceae, Candida albicans and Staphylococcus aureus. 72.2 per cent of VAP patients had monomicrobial and 27.8 per cent had polymicrobial infection. Out of the 24 isolates obtained from patients with VAP, seven (29.2 per cent) were MDR pathogens. ESBL and MBL production was detected in 40 per cent and 20 per cent of Klebsiella pneumoniae isolated in our study. Around 50 per cent of isolates associated with late-onset VAP were MDR, while 22.2 per cent isolates obtained from patients with earlyonset VAP were MDR.

CONCLUSION

VAP is a nosocomial pneumonia that is common among ventilated patients. The aetiological agents vary from common organisms to MDR pathogens that are difficult to treat. A proper knowledge of MDR pathogens and early isolation followed by prevention of prolonged antibiotic therapy can reduce the mortality of late onset VAP.

Diagnosis, prevention, and management of statin adverse effects and intolerance: Canadian Working Group Consensus update

The Proceedings of a Canadian Working Group Consensus Conference, first published in 2011, provided a summary of statin-associated adverse effects and intolerance and management suggestions. In this update, new clinical studies identified since then that provide further insight into effects on muscle, cognition, cataracts, diabetes, kidney disease, and cancer are discussed. Of these, the arenas of greatest controversy pertain to purported effects on cognition and the emergence of diabetes during long-term therapy. Regarding cognition, the available evidence is not strongly supportive of a major adverse effect of statins. In contrast, the linkage between statin therapy and incident diabetes is more firm. However, this risk is more strongly associated with traditional risk factors for new-onset diabetes than with statin itself and any possible negative effect of new-onset diabetes during statin treatment is far outweighed by the cardiovascular risk reduction benefits. Additional studies are also discussed, which support the principle that systematic statin rechallenge, and lower or intermittent statin dosing strategies are the main methods for dealing with suspected statin intolerance at this time.

Colonic tumour precipitating caecal volvulus within a diaphragmatic hernia

An 85-year-old woman presented with sudden onset of generalised abdominal pain and absolute constipation for 4 d. On examination she had a distended abdomen. Plain abdominal radiograph revealed a gas filled viscous within the left upper quadrant. Subsequent computed tomography suggested caecal volvulus herniated through a left diaphragmatic hernia. The patient underwent reduction of the internal hernia, right hemicolectomy and mesh repair of the diaphragmatic hernia. Postoperative recovery was uneventful. Histology revealed a Dukes’ A colonic cancer within the caecum. Herniation of caecal volvulus through a diaphragmatic hernia is a very rare condition and may have been precipitated by the colonic tumour.

Utilisation of skilled birth attendance in Northern Nigeria: a cross-sectional survey

OBJECTIVE

to determine the level and determinants for utilisation of Skilled Birth Attendance (SBA).

METHODS

a population-based survey using a structured questionnaire was conducted in Goya and Tundunya political wards of Katsina state from May to June 2012. Four hundred women aged 15-49 years who had delivered a baby within two years prior to the study were asked about birth attendance during antenatal care (ANC), childbirth and postnatal period of their most recent birth. Logistic regression analysis was performed to obtain independent predictors of skilled birth attendance (SBA).

FINDINGS

of the 400 women recruited for the study, 145 (36.3%) received antenatal care, 52 (13%) had their births assisted by skilled personnel and 88 (22%) received postnatal care from skilled birth attendants. Of the 52 women who had their births attended by skilled birth attendants only 29 (56%) had their births in a health facility. Maternal education, husband's occupation, presence of complication and previous place of childbirth were found to be statistically significant predictors for SBA utilisation. Barriers to SBA utilisation identified included lack of health care provider, lack of equipment and supplies and poverty. Enablers mentioned included availability of staff, husband's approval and affordable service.

CONCLUSION

women are more likely to utilise SBA with the availability of skilled personnel, strengthening of the health system and intervention to remove user fees for maternal health services. Joint effort should be made by government and community leaders to promote girl's education and to encourage men's involvement in maternal health services.

Australian community pharmacists' awareness and practice in supporting secondary prevention of cardiovascular disease

BACKGROUND

Pharmacists are well placed to identify, prevent and resolve medicine related problems as well as monitor the effectiveness of treatments in cardiovascular disease (CVD). Pharmacists' interventions in CVD secondary prevention have been shown to improve outcomes for clients with established CVD.

OBJECTIVE

To explore the scope of pharmacists' activities in supporting CVD secondary prevention.

SETTING

Community pharmacies in New South Wales, Australia.

METHODS

Twenty-one in-depth, semi-structured interviews with a range of community pharmacists were conducted. All interviews were audio-recorded and transcribed ad verbatim. Data were analyzed using a 'grounded-theory' approach by applying methods of constant comparison.

MAIN OUTCOME MEASURE

Community pharmacists' awareness and current practice in supporting secondary prevention of CVD.

RESULTS

Four key themes identified included 'awareness', 'patient counselling', 'patient monitoring', and 'perceptions of the role of pharmacists in CVD secondary prevention'. The pharmacists demonstrated a moderate understanding of CVD secondary prevention. There was considerable variability in the scope of practice among the participants, ranging from counselling only about medicines to providing continuity of care. A minority of pharmacists who had negative beliefs about their roles in CVD secondary prevention offered limited support to their clients. The majority of pharmacists, however, believed that they have an important role to play in supporting clients with established CVD.

CONCLUSION

Community pharmacists in Australia make a contribution to the care of clients with established CVD despite the gap in their knowledge and understanding of CVD secondary prevention. The scope of practice in CVD secondary prevention ranged from only counselling about medicines to offering continuity of care. The extent of pharmacists' involvement in offering disease management appears to be influenced by their beliefs regarding what is required within their scope of practice.

Prevalence of anemia among adults with newly diagnosed HIV/AIDS in China

BACKGROUND

The prevalence of anemia among antiretroviral-naïve HIV-infected patients in China has not been well characterized. We conducted a cross-sectional study to estimate the prevalence of anemia among Chinese adults with newly diagnosed HIV/AIDS.

METHODS

One thousand nine hundred and forty-eight newly diagnosed HIV-infected patients in China were selected during 2009 and 2010. Serum samples obtained from each individual were collected to measure hemoglobin levels. Demographics and medical histories were recorded. Factors associated with the presence of anemia were analysed by logistic regression.

RESULTS

Among the 1948 patients, 75.8% were male. Median age was 40 years (range: 18-80 years). The overall prevalence of anemia among HIV-infected patients was 51.9% (51.5% among men, 53.2% among women). The prevalences of mild anemia, of moderate anemia, of severe anemia were 32.4%, 17.0%, and 2.5%, respectively. The prevalence of anemia was higher among ethnic minority patients than among the Han patients (70.9% versus 45.9%). The prevalence of anemia increased with increasing age (49.6%, 53.5% and 60.1% among patients who were 18-39, 40-59, and ≥ 60 years of age respectively) and with decreasing CD4 count (14.0%, 22.4%, 50.7%, and 74.6% among patients with CD4 count of ≥ 350, 200-349, 50-199, and <50 cells/mm(3) respectively). The logistic regression analysis showed that older age, lower CD4 count and minority ethnicity were significantly associated with an increased risk of anemia.

CONCLUSIONS

Anemia is highly prevalent among Chinese adults with newly diagnosed HIV/AIDS, but severe anemia is less prevalent in this population. Older age, lower CD4 count and minority ethnicity are associated with an increased risk of anemia.

Office-based physical activity and nutrition intervention: barriers, enablers, and preferred strategies for workplace obesity prevention, Perth, Western Australia, 2012

INTRODUCTION

Workplace health promotion programs to prevent overweight and obesity in office-based employees should be evidence-based and comprehensive and should consider behavioral, social, organizational, and environmental factors. The objective of this study was to identify barriers to and enablers of physical activity and nutrition as well as intervention strategies for health promotion in office-based workplaces in the Perth, Western Australia, metropolitan area in 2012.

METHODS

We conducted an online survey of 111 employees from 55 organizations. The online survey investigated demographics, individual and workplace characteristics, barriers and enablers, intervention-strategy preferences, and physical activity and nutrition behaviors. We used χ(2) and Mann-Whitney U statistics to test for differences between age and sex groups for barriers and enablers, intervention-strategy preferences, and physical activity and nutrition behaviors. Stepwise multiple regression analysis determined factors that affect physical activity and nutrition behaviors.

RESULTS

We identified several factors that affected physical activity and nutrition behaviors, including the most common barriers ("too tired" and "access to unhealthy food") and enablers ("enjoy physical activity" and "nutrition knowledge"). Intervention-strategy preferences demonstrated employee support for health promotion in the workplace.

CONCLUSION

The findings provide useful insights into employees' preferences for interventions; they can be used to develop comprehensive programs for evidence-based workplace health promotion that consider environmental and policy influences as well as the individual.

Consistent condom use with regular, paying, and casual male partners and associated factors among men who have sex with men in Tamil Nadu, India: findings from an assessment of a large-scale HIV prevention program

BACKGROUND

Men who have sex with men (MSM) are a marginalized population at high risk for HIV infection. Promoting consistent condom use (CCU) during anal sex is a key risk reduction strategy for HIV prevention among MSM. To inform effective HIV prevention interventions, we examined the factors associated with CCU among MSM with their regular, paying, and casual partners, as well as with all three types of partners combined.

METHODS

Data for this analysis were from a large-scale bio-behavioural survey conducted during 2009-2010 in Tamil Nadu, India. MSM aged 18 years or older were recruited for the survey using time-location cluster sampling at cruising sites in four districts of Tamil Nadu. Binary logistic regression analyses were conducted to assess the association of CCU with selected socio-demographic characteristics and other contextual factors.

RESULTS

Among 1618 MSM interviewed, CCU during anal sex with regular, paying, and a casual male partner was 45.3%, 50.8% and 57.9%, respectively. CCU with all three types of partners combined was 52.6%. Characteristics associated with increased odds for CCU with MSM having all three types of partners combined were frequent receptive anal sex acts with regular partners (adjusted odds ratio [AOR] 2.17, 95% confidence interval [CI] 1.01-4.65), fewer number of casual partners (AOR 3.41, 95% CI 1.50-7.73) and membership in a community-based organization (CBO) for MSM (AOR 3.54, 95% CI 1.62-7.74). CCU with regular partners was associated with membership in a CBO (AOR 1.96, 95% CI 1.23-3.11), whereas CCU with paying, and casual male partners was associated with perceived higher risk of acquiring HIV (AOR 1.92, 95% CI 1.22-3.01) and exposure to any HIV prevention intervention (AOR 3.62, 95% CI 1.31-10.0), respectively. Being aged 26 years or older, being in debt, and alcohol use were factors associated with inconsistent condom use across partner types.

CONCLUSION

HIV interventions among MSM need to promote CCU with all types (regular, paying, and causal) of male partners, and need to reach MSM across all age groups. In addition to enhancing interventions that focus on individual level risk reduction, it is important to undertake structural interventions that promote social acceptance of same-sex sexuality and address contextual barriers to condom use such as alcohol use.

Impact of weight change during the course of concurrent chemoradiation therapy on outcomes in stage IIIB non-small cell lung cancer patients: retrospective analysis of 425 patients

PURPOSE

We retrospectively investigated the impact of weight change (WC) during concurrent chemoradiation therapy (C-CRT) on clinical outcomes of stage 3B non-small cell lung cancer (NSCLC) patients.

METHODS AND MATERIALS

A total of 425 patients treated with C-CRT were included. All patients received 60 to 66 Gy of thoracic radiation therapy concurrently with 1 to 3 cycles of platinum-based chemotherapy. Pre- and posttreatment weight measurements on first and last days of C-CRT were used for WC. Patients were divided into 2 groups: group 1=weight loss (WL); group 2=weight preservation/gain (WP) for comparative analyses.

RESULTS

Following C-CRT, 252 patients (59.3%) experienced WL, while 89 patients (20.9%) and 84 patients (19.8%) showed WP or WG. At median 24.2 months of follow-up, 142 patients (33.4%) were alive (84 WP [48.6%] and 58 WL [23.0%]), and 58 (13.6%) of them were free of disease progression (41 [23.7%] for WP and 17 [6.7%] for WL). Median overall survival (OS), locoregional progression-free survival (LRPFS), progression-free survival (PFS), and distant metastases-free survival (DMFS) for the entire population were 22.8, 14.4, 10.6, and 11.7 months, respectively. Intergroup comparisons between WP and WL cohorts revealed significantly superior OS, LRPFS, PFS, and DMFS in WP patients (P<.05 for each). On multivariate analyses, only WL and advanced T stage were associated with poor prognosis (P<.05).

CONCLUSIONS

Present results in 425 stage 3B NSCLC patients demonstrated that WL during C-CRT is strongly associated with inferior survival outcomes compared to WP. This emerging finding might be useful by forming an encouraging basis for future investigations in facilitating a way to improve the outcomes of these patients experiencing WL during C-CRT.

Menstrual Pattern among Unmarried Women from Northern India

BACKGROUND

Menstruation disorders are also responsible for emotional, physical, behavioural and dietary practice changes. These changes affect their normal functioning and social life. The present study was carried out to find the prevalence of menstrual problems among unmarried girls of Chandigarh, India and to compare their knowledge and beliefs regarding menstruation in different sub-groups.

METHODOLOGY

A community based cross-sectional study was conducted among 744 unmarried females in Rural, Urban and Slum strata of UT Chandigarh, India. Data were collected using a self-administered structured questionnaire on menstruation. Chi-square value was used for testing statistical significance.

RESULTS

The mean age of the respondents was 16.84±3.05 years. Maximum respondents (40.9%) were educated up to 10th standard/High school. 448 (60.2%) were aware of menstruation before starting of menarche. Awareness was found to be significantly associated (p=0.02) with age. Socio-economic status and prior knowledge of respondents was also found to be significantly associated (p< 0.001). 61% (454) of the respondents had a regular flow during menses. Normal flow was reported by 70.2 %(522) of the respondents. Dysmenorrhea was found to be the most common problem suffered by 429 (57.7%) respondents.

CONCLUSION

Menstrual hygiene is an issue that needs to be addressed at all levels. A variety of factors are known to affect menstrual behaviors, the most influential ones being economic status. It is essential to design a mechanism to address and for the access of healthy menstrual practices.

A model for provision of ENT health care service at primary and secondary hospital level in a developing country

ENT problems are the most common reason for a visit to a doctor in both rural and urban communities. In many developing countries, there is a lack of ENT specialists and overburdened hospital facilities. To date, there is no comprehensive study that has evaluated the spectrum of ENT disorders in a rural community.

METHODS

A prospective study was done for a period of three years to profile the cases presenting to the outpatient clinic in a secondary care hospital and in the camps conducted in tribal areas in Vellore District of Tamil Nadu, India. Trained community volunteers were used to identify ENT conditions and refer patients.

RESULTS

A total of 2600 patients were evaluated and treated. Otological symptoms were the most commonly reported with allergic rhinitis being the second most commonly reported. Presbycusis was the most common disability reported in the rural community. The other symptoms presented are largely related to hygiene and nutrition.

CONCLUSION

Using trained community workers to spread the message of safe ENT practices, rehabilitation of hearing loss through provision of hearing aids, and the evaluation and surgical management by ENT specialist helped the rural community to access the service.

Long-term follow-up of paediatric anorectal anomalies and the role and efficacy of parent support groups for such conditions

BACKGROUND/PURPOSE

There are a multitude of parent support groups for most life situations and medical conditions. The aim of this study was to discover defining characteristics and to evaluate the structure and effectiveness of parent support groups in paediatric anorectal anomalies.

METHODS

Over 200 non-profit organisations and parent support groups were sent questionnaires to determine their effectiveness. Many of these were excluded as they were deemed not relevant to the final study. A final 20 groups were included for review, questions were based around origins, activities, education and evaluation, organisational structure and their affiliations with the health care team.

RESULTS

Most groups had similar origins, usually an educated parent who had a child born with the condition and a zest for further knowledge and understanding and a desire to share this with others in a similar situation. Only 20% received government funding; few had paid staff and half had good relations with the local medical and paramedical fraternity. The majority had a team of long-term enthusiastic volunteers who remained with the group to support others long after their own child was no longer a concern.

CONCLUSIONS

Some support groups offer a valuable service to families alongside the medical and paramedical fraternity. These groups provide families with the day-to-day lived experiences through social media, networking and meetings. Some provide more formal educational conferences designed to bring families, the medical and paramedical fraternity together to learn valuable lessons from each other.
