Abstract
The COVID-19 pandemic has had a significant impact on how field-based research is being conducted globally. Given the challenges of undertaking fieldwork during epidemics and the need for mixed methods research to address the social, political, and economic issues related to epidemics, there is a small but growing body of evidence in this area. To contribute to the logistical and ethical considerations for conducting research during a pandemic, we draw on the challenges and lessons learnt from adapting methods for two research studies conducted in 2021 during the COVID-19 pandemic in low- and middle-income country (LMIC) settings: (1) in-person research in Uganda and (2) combined remote and in-person research in South and Southeast Asia. Our case studies focus on data collection and demonstrate the feasibility of conducting mixed methods research, even with many logistical and operational constraints. Social science research is often used to identify the context of specific issues, to provide a needs assessment, or inform longer-term planning; however, these case studies have shown the need to integrate social science research from the start of a health emergency and in a systematic way. Social science research during future health emergencies can also inform public health responses during the emergency. It is also crucial to collect social science data after health emergencies to inform future pandemic preparedness. Finally, researchers need to continue research on other public health issues that are ongoing even during a public health emergency.

Abstract
Patients with suspected enteric (typhoid and paratyphoid) fever are predominantly managed as outpatients in endemic regions. Nonspecific clinical presentation, lack of accurate diagnostic tools, and widespread antimicrobial resistance makes management challenging. Resistance has been described for all antimicrobials including chloramphenicol, amoxycillin, trimethoprim-sulfamethoxazole, ciprofloxacin, ceftriaxone, and azithromycin. No significant differences have been demonstrated between these antimicrobials in their ability to treat enteric fever in systematic reviews of randomized controlled trials (RCTs). Antimicrobial choice should be guided by local resistance patterns and national guidance. Extensively drug-resistant typhoid isolates require treatment with azithromycin and/or meropenem. Combining antimicrobials that target intracellular and extracellular typhoid bacteria is a strategy being explored in the Azithromycin and Cefixime in Typhoid Fever (ACT-SA) RCT, in progress in South Asia. Alternative antimicrobials, such as the oral carbapenem, tebipenem, need clinical evaluation. There is a paucity of evidence to guide the antimicrobial management of chronic fecal carriers.

Abstract
Dextrocardia is an unusual inherent positioning of the heart: during fetal life, the heart is flipped to the right side rather than the usual left side. Situs inversus is a rare congenital ailment in which the main internal organs are rearranged or reflected from their natural positions, and when both conditions are present, it is called situs inversus totalis. The majority of the people with situs inversus totalis are unaware of the situation they have because most of them are asymptomatic. It is usually discovered incidentally when they consult the doctor for an unrelated condition. We are reporting a case of a 55-year-old woman who was found to have a situs inversus totalis with an absent left kidney.

Abstract
Background: When the novel coronavirus – SARS-CoV-2 – started to spread globally, there was a call for social and behavioral scientists to conduct research to explore the wider socio-cultural contexts of coronavirus disease 2019 (COVID-19), to understand vulnerabilities, as well as to increase engagement within communities to facilitate adoption of public health measures. In this manuscript, we describe the protocol for a study conducted in Indonesia, Nepal, and Vietnam. In the study, we explore how the COVID-19 pandemic is affecting individuals and their communities. We focus on the wider health and economic impacts of COVID-19, in particular emerging and increased burden on mental health, as well as new or deepened vulnerabilities in the communities. The introduction of vaccines has added another layer of complexity and highlights differences in acceptance and inequalities around access. Methods: We use mixed methods, combining survey methods and social media surveillance to gain a picture of the general situation within each country, with in-depth qualitative methods to gain a deeper understanding of issues, coupled with a synergistic engagement component. We also include an exploration of the role of social media in revealing or driving perceptions of the pandemic more broadly. Participants include health workers and members of communities from 13 sites across the three countries. Data collection is spread across two phases. Phase 1 is concerned with exploring lived experiences, impacts on working lives and livelihoods, mental health and coping strategies. Phase 2 is concerned with acceptance of COVID-19 vaccines, factors that increase and reduce acceptance, and factors that influence access. Conclusions: We will disseminate findings in multiple ways including short reports and policy briefs, articles in peer-reviewed journals, and digital diaries will be edited into short films and uploaded onto social media sites.

Abstract
Background: Typhoid and paratyphoid fever (enteric fever) is a common cause of non-specific febrile infection in adults and children presenting to health care facilities in low resource settings such as the South Asia. A 7-day course of a single oral antimicrobial such as ciprofloxacin, cefixime, or azithromycin is commonly used for its treatment. Increasing antimicrobial resistance threatens the effectiveness of these treatment choices. We hypothesize that combined treatment with azithromycin (active mainly intracellularly) and cefixime (active mainly extracellularly) will be a better option for the treatment of clinically suspected and culture-confirmed typhoid fever in South Asia. Methods: This is a phase IV, international multi-center, multi-country, comparative participant-and observer-blind, 1:1 randomised clinical trial. Patients with suspected uncomplicated typhoid fever will be randomized to one of the two interventions: Arm A: azithromycin 20mg/kg/day oral dose once daily (maximum 1gm/day) and cefixime 20mg/kg/day oral dose in two divided doses (maximum 400mg bd) for 7 days, Arm B: azithromycin 20mg/kg/day oral dose once daily (max 1gm/day) for 7 days AND cefixime-matched placebo for 7 days. We will recruit 1500 patients across sites in Bangladesh, India, Nepal, and Pakistan. We will assess whether treatment outcomes are better with the combination after one week of treatment and at one- and three-months follow-up. Discussion: Combined treatment may limit the emergence of resistance if one of the components is active against resistant sub-populations not covered by the other antimicrobial activity. If the combined treatment is better than the single antimicrobial treatment, this will be an important result for patients across South Asia and other typhoid endemic areas.

Abstract
Background Azithromycin and trimethoprim-sulfamethoxazole (SXT) are widely used to treat undifferentiated febrile illness (UFI). We hypothesized that azithromycin is superior to SXT for UFI treatment, but the drugs are noninferior to each other for culture-confirmed enteric fever treatment. Methods We conducted a double-blind, randomized, placebo-controlled trial of azithromycin (20 mg/kg/day) or SXT (trimethoprim 10 mg/kg/day plus sulfamethoxazole 50 mg/kg/day) orally for 7 days for UFI treatment in Nepal. We enrolled patients >2 years and <65 years of age presenting to 2 Kathmandu hospitals with temperature ≥38.0°C for ≥4 days without localizing signs. The primary endpoint was fever clearance time (FCT); secondary endpoints were treatment failure and adverse events. Results From June 2016 to May 2019, we randomized 326 participants (163 in each arm); 87 (26.7%) had blood culture–confirmed enteric fever. In all participants, the median FCT was 2.7 days (95% confidence interval [CI], 2.6–3.3 days) in the SXT arm and 2.1 days (95% CI, 1.6–3.2 days) in the azithromycin arm (hazard ratio [HR], 1.25 [95% CI, .99–1.58]; P = .059). The HR of treatment failures by 28 days between azithromycin and SXT was 0.62 (95% CI, .37–1.05; P = .073). Planned subgroup analysis showed that azithromycin resulted in faster FCT in those with sterile blood cultures and fewer relapses in culture-confirmed enteric fever. Nausea, vomiting, constipation, and headache were more common in the SXT arm. Conclusions Despite similar FCT and treatment failure in the 2 arms, significantly fewer complications and relapses make azithromycin a better choice for empirical treatment of UFI in Nepal. Clinical Trials Registration NCT02773407.

Abstract
Para-methoxycinnamic acid (PMCA) and Ethyl-p-methoxycinnamate (EPMC) are reported to possess neuroprotective effect in reversing an acute memory deficit. However, there is a dearth of evidence for their therapeutic effect in chronic memory deficit. Thus, there is a scope to study these derivatives against the chronic model of cognitive dysfunction. The present study was aimed to determine the cognitive enhancing activity of PMCA and EPMC in aluminum-induced chronic dementia. Cognitive enhancing property of PMCA and EPMC was assessed using Morris water maze by analyzing spatial memory parameters such as escape latency, D-quadrant latency, and island entries. To find a possible mechanism, the effect of test compounds on altered acetylcholinesterase (AChE) activity and oxidative stress was determined in the hippocampus and frontal cortex of rats. Docking interaction of these derivatives with acetylcholinesterase enzyme and glutamate receptors was also studied. Treatment with PMCA and EPMC showed a significant improvement in spatial memory markers and altered hippocampal AChE activity in rats with cognitive dysfunction. The implication of hippocampal and cortical oxidative stress in memory impairment was confirmed with decreased catalase/increased thiobarbituric acid reactive substances (TBARS) in rats. PMCA and EPMC reversed the oxidative stress in the brain by negatively affecting TBARS levels. Against depleted catalase levels, PMCA was more effective than EPMC in raising the depleted catalase levels. In silico analysis revealed poor affinity of EPMC and PMCA with AChE enzyme and glutamate receptor. To conclude, PMCA and EPMC exerted cognitive enhancing property independent of direct AChE and glutamate receptor inhibition.

Abstract
OBJECTIVES To assess the prevalence of human immunodeficiency virus (HIV), hepatitis C virus (HCV), and hepatitis B virus (HBV) co-infections among people living with HIV (PLHIV) in Nepal. METHODS A sample of 677 PLHIV representing key affected populations (KAP) in Nepal, who were undergoing antiretroviral (ART) therapy in ART clinics around the country, were voluntarily enrolled in the study. Rapid kit-based testing followed by ELISA for validation was performed, focusing on HBV surface antigen (HBsAg) and antibodies against HCV (anti-HCV). A multivariate logistic regression model was used to identify factors associated with HBV and HCV co-infection. RESULTS HCV and HBV co-infection among the 677 PLHIV was found to be 19% (95% confidence interval (CI) 16.6-22.7%) and 4.4% (95% CI 3.1-6.6%), respectively. The Eastern Region had the highest percentage of HCV infection (48%). The age group with the highest rates of co-infection was 30-39 years (58% and 70%, respectively, for HCV and HBV co-infection). After adjusting for confounding, males were more likely to have HBV co-infection than females (adjusted odds ratio (AOR) 4.61, 95% CI 1.42-14.98). Similarly, PLHIV who were male (AOR 5.7, 95% CI 2.06-15.98), had a secondary level of education (AOR 3.04, 95% CI 1.06-8.70), or who were drug users (AOR 28.7, 95% CI 14.9-55.22) were significantly more likely to have HCV co-infection. CONCLUSION This first ever national assessment of HIV, HBV, and HCV co-infection performed among PLHIV in Nepal demonstrates that HCV and HBV infections are a health threat to this population and that interventions are required to mitigate the effects of co-infection and to prevent further morbidity and mortality.

Abstract
This longitudinal study was conducted in BP Koirala Institute of Health Sciences (BPKIHS), a Medical University situated in eastern Nepal, between May 2001 and December 2001. The main objective of the study was to identify the role of adenosine deaminase (ADA) activity in patients with visceral leishmaniasis (VL) for management. There was a significant increase in mean ADA activity in sera of 49 patients with VL (323.71±184.51 IU/L) compared with 50 samples of control groups (47.11±24.94 IU/L) from the same endemic area ( P<0.001). ADA activities were found to be significantly decreased (50.35±41.35 IU/L) in follow-up cases ( n = 19) after 30 days with sodium stibogluconate treatment at a dose of 20 mg/kg/day intramuscularly. The fall in the level of ADA (after treatment) in follow-up cases correlated with the cure of disease, as evident from improvement of vital signs and symptoms and the absence of Leishmania donavani bodies in the sera. The study therefore suggests the possibility of using human serum ADA as a convenient marker to evaluate the diagnosis of VL to support the clinical findings, especially in those settings where there is a lack of highly qualified personnel and diagnostic facilities.

Abstract
In this study, we followed the genomic, lipidomic and metabolomic changes associated with the selection of miltefosine (MIL) resistance in two clinically derived Leishmania donovani strains with different inherent resistance to antimonial drugs (antimony sensitive strain Sb‐S; and antimony resistant Sb‐R). MIL‐R was easily induced in both strains using the promastigote‐stage, but a significant increase in MIL‐R in the intracellular amastigote compared to the corresponding wild‐type did not occur until promastigotes had adapted to 12.2 μM MIL. A variety of common and strain‐specific genetic changes were discovered in MIL‐adapted parasites, including deletions at the LdMT transporter gene, single‐base mutations and changes in somy. The most obvious lipid changes in MIL‐R promastigotes occurred to phosphatidylcholines and lysophosphatidylcholines and results indicate that the Kennedy pathway is involved in MIL resistance. The inherent Sb resistance of the parasite had an impact on the changes that occurred in MIL‐R parasites, with more genetic changes occurring in Sb‐R compared with Sb‐S parasites. Initial interpretation of the changes identified in this study does not support synergies with Sb‐R in the mechanisms of MIL resistance, though this requires an enhanced understanding of the parasite's biochemical pathways and how they are genetically regulated to be verified fully.

Abstract
BACKGROUND The anecdotal burden of morbidity secondary to motorbike accidents is thought to enormous by personnel involved in trauma care. The objective of the present study is to ascertain patterns and association of injuries and causes of mortality in a cohort of motorbike accident victims. METHODS A retrospective chart review of 1337 motorbike accident admissions B and B Hospital in Kathmandu between January 2009 and December 2010 was undertaken. RESULTS Majority of victims were between 20 to 50 years [1230 (92%) males]. Lower extremity injuries comprised on 816 (61% of total admissions). Tibia fractures were the most common injury in isolation, multiple injury, as well as polytrauma, and a vast majority of these were open fractures. Multiple injuries were seen in 82 (6.1%) patients and 33 (2.5% of Total) patients were polytraumatized. An amputation was necessary in 16 (1.2%) patients and emergent fasciotomy for compartment syndrome was necessary in 23 (1.7%) cases of tibia fractures and 39 (2.2%) of foot and ankle injuries. A floating joint injury was present in 24 (1.8%) patients.. A fat embolism syndrome (FES) was diagnosed in 8 (0.6%) patients. The overall mortality was 0.45% (6 patients). CONCLUSIONS Motorbike accident is an important cause of morbidity and mortality in Kathmandu, and often involves a very productive age group. There is an imminent need to address this public health problem.

Abstract
Synovial chondromatosis is not so rare intra-articular condition secondary to synovial metaplasia, that affects the knee joint. Extra-articular synovial chondromatosis however is an extremely rare condition that usually involves the synovial sheath or bursa of the foot or hand. We present two cases of synovial chondromatosis, one intra and one extra-articular. The first case was a 25 year old lady who presented with pain, swelling and restricted range of motion of left knee and was found to have an intra-articular synovial chondromatosis which was treated successfully by joint debridement. The second case was that of a 22 year old man who presented with right knee pain and was diagnosed to have an extra-articular synovial chondromatosis of his right medial hamstring tendon sheath, excision of which resulted in complete relief of symptoms.

Abstract
Although widespread resistance of Leishmania donovani and L. infantum against miltefosine (MIL) and paromomycin (PMM) has not yet been demonstrated, both run the risk of resistance selection. Unraveling the dynamics and mechanisms of resistance development is key to preserve drug efficacy in the field. In this study, resistance against PMM and MIL was experimentally selected in vitro in intracellular amastigotes of several strains of both species with different antimony susceptibility background. To monitor amastigote susceptibility, microscopic determination of IC50-values and promastigote back-transformation assays were performed. Both techniques were also used to evaluate the susceptibility of field isolates from MIL-relapse patients. PMM-resistance could readily be selected in all species/strains, although promastigotes remained fully PMM-susceptible. Successful MIL-resistance selection was demonstrated only by promastigote back-transformation at increasing MIL-concentrations upon successive selection cycles. Important to note is that amastigotes with the MIL-resistant phenotype could not be visualized after Giemsa staining; hence, MIL-IC50-values showed no shift. The same phenomenon was observed in a set of recent clinical isolates from MIL-relapse patients. This study clearly endorses the need to use intracellular amastigotes for PMM- and MIL-susceptibility testing. When monitoring MIL-resistance, promastigote back-transformation should be used instead of the standard Giemsa staining. In-depth exploration of the mechanistic background of this finding is warranted.

Abstract
BACKGROUND The traumatic or degenerative internal derangement of the knee requires certain investigations for the establishment of diagnosis, in addition to clinical history and a thorough physical examination. The use of arthrography and arthroscopy improves the accuracy of the diagnosis. MRI scanning of the knee joint has often been regarded as the noninvasive alternative to diagnostic arthroscopy. OBJECTIVE The purpose of the study was to correlate clinical and low field MRI findings with arthroscopy in internal derangement of the knee. METHODS Forty one patients with suspected internal derangement of the knee were subjected to MR examination followed by arthroscopy. Clinical criteria used were history, mode of injury, Mc Murray, Apley grinding, Thessaly test for meniscal injury. Drawer test was considered to be essential for clinical diagnosis of cruciate ligament injury. MRI of the knee was performed in low field open magnet (0.35T, Magnetom C, Seimens). Arthroscopy was done within two months of MR examination and was considered gold standard for the internal derangement of the knee. RESULTS The sensitivity, specificity, diagnostic accuracy of clinical examination were 96.1%, 33.3% and 73.1% respectively for medial meniscal tear; 38.4%, 96.4% and 78.1% respectively for lateral meniscal tear. The sensitivity, specificity, diagnostic accuracy of MRI were 92.3%,100% and 95.1% for medial meniscal tear; 84.6%96.4% and 92.6% respectively for lateral meniscal tear. CONCLUSION Clinical examination showed higher sensitivity for medial meniscal tear compared to MRI, however with low specificity and diagnostic accuracy. Low field MRI showed high sensitivity, specificity, diagnostic accuracy for meniscal and cruciate ligament injury, in addition to associated derangement like articular cartilage damage, synovial thickening.

Abstract
The Visceral Leishmaniasis (VL) control program in Nepal launched in 1993 includes provision of free diagnostic test, treatment along with vector control by indoor residual spraying. However, even after 14 years the disease is far from being controlled. Elimination of VL by 2015 has recently been identified as a regional priority with high level of political commitment. We analyzed the VL control effort in Nepal over the period 1994-2006 and tried to formulate recommendations for the VL elimination initiative. To document performance of the VL control program in Nepal we used literature review and a case study. First, we reviewed articles on VL in Nepal published in medical journals through Pubmed, ISI Web of Science, Google scholar and by hand searching. Secondly, the grey literature, mainly the reports on VL drafted by the Ministry of Health was reviewed for the period 1994-2006. Thirdly, a case study is presented to analyze the performance of the VL elimination program in a "pilot district", where the program was launched in 2006. There are only few studies available on VL in Nepal discussing the epidemiology, diagnosis, treatment, vector bionomics, human behavior and prevention. The review of the grey literature from 1994-2006 revealed that the VL incidence rate remained almost constant since 1993 despite the control efforts. The case study showed that there is a lack of trained human resources, laboratory facilities and treatment guidelines which is hindering the decentralization of the VL elimination program.

Abstract
Cough is one of the most common symptom for which patients seek medical attention from primary care physicians and pulmonologists. Although tuberculosis and other lung infections are common throughout the developing world, they are not among the most common causes of chronic cough. We report a case of a 23 years old male who presenting to the outpatient clinic with chronic cough not responding to regular and symptomatic treatment that was diagnosed to have thymoma. After all the common causes for chronic cough have been ruled out, unusual causes should also be considered in the differential diagnosis.

Abstract
This study was conducted to explore the most effective vector control tool among indoor residual spraying (IRS), long lasting insecticidal nets (LLINs) and ecological vector management (EVM) as a part of the regional visceral leishmaniasis elimination initiative. Alpha-cypermethrin as IRS, PermaNet as LLINs and plastering the inner walls of houses with lime as EVM were the interventions. One baseline and three follow-up entomological surveys were carried out in all arms using CDC miniature light traps (LT) and mouth aspirators. Comparisons were made between intervention arms and control arms with pre-intervention and post-intervention vector densities. Light traps were found more efficient in the collection of Phlebotomus argentipes in comparison with aspiration. Vector densities were significantly low in both IRS arm (p=0.009 in LT and p<0.001 in aspirator collections) and LLIN arm (p=0.019 in LT and p=0.023 in aspirator collections) in comparison with control arm. However, in EVM arm, there was no significant difference in P. argentipes sand fly density in comparison with control arm (p=0.785) in LT collections in follow-up surveys. Hence, IRS was found most effective control measure to decrease vector density. LLINs were also found effective and can be considered as a promising alternative vector control tool in VL elimination initiative.

Abstract
OBJECTIVE To document ownership and use of bednets with its determinants in the visceral leishmaniasis (VL)-endemic region where mainly non-insecticide impregnated nets are available through commercial channels, and bednets are being considered as a leishmaniasis vector control measure. METHODS In August-September 2006, semi-structured household (HH) questionnaires and observation guides were used in a random sample of 1330 HHs in VL-endemic districts of India and Nepal to collect data on VL knowledge, HH socio-economic status, bednet ownership and use patterns. An asset index was constructed to allow wealth ranking of the HH. A binary logistic response General Estimating Equations model was fitted to evaluate the determinants of bednet ownership and use. RESULTS The proportion of HHs with at least one bednet purchased on the commercial market was 81.5% in India and 70.2% in Nepal. The bednets were used in all seasons by 50.6% and 54.1% of the Indian and Nepalese HH owning a bed net. There was striking inequity in bednet ownership: only 38.3% of the poorest quintile in Nepal owned at least one net, compared to 89.7% of the wealthiest quintile. In India, the same trend was observed though somewhat less pronounced (73.6%vs. 93.7%). Multivariate analysis showed that poverty was an important independent predictor for not having a bednet in the HH [OR 5.39 (2.90-10.03)]. CONCLUSION Given the inequity in commercial bednet ownership, free distribution of insecticide-treated bednets to the general population seems imperative to achieve a mass effect on vector density.

Abstract
The sandflies that transmit the parasites causing human visceral leishmaniasis (VL) can be controlled by several methods, including indoor residual spraying (IRS), the use of long-lasting insecticidal nets (LLIN) and ecological vector management (EVM). The financial costs of each of these three methods of sandfly control have recently been assessed and compared, in a multi-centre study based on the Indian sub-continent. In each of the four study sites (two in Nepal and one each in India and Bangladesh), 24 neighbourhoods were randomly selected in districts with high incidences of VL. The costs of the three interventions were then prospectively assessed in each study neighbourhood, in the local currency, and then converted to U.S. dollars at the prevailing exchange rate in the country concerned. The costs of IRS, which ranged from U.S.$2.4-11.7 (mean = U.S.$5.9) per household-year, were greater than those of LLIN (U.S.$3.5-5.1/household-year, with a mean of U. S.$4.5) but less than those of EVM (U. S.$5.0- 14.0/household-year, with a mean of U.S.$8.7). These results indicate that LLIN and IRS may be the cheaper options for the control of sandflies on the Indian sub-continent, and that EVM should perhaps only be taken up as a complimentary and voluntary method. Various combinations of these interventions (based on country-specific social and economic factors) may, however, be the best and most cost-effective choice.

Abstract
A glutathione redox cycle is a major antioxidant defense system for the detoxification of reactive oxygen species within erythrocytes. Reactive oxygen species such as superoxide anions, hydrogen peroxide and hydroxyl radicals are generated as a host defense mechanism for killing of engulfed Leishmania donovani, a causative agent of visceral leishmaniasis, are capable of damaging lipids and other biomolecules when produced in excess. Erythrocytes are most vulnerable to Reactive oxygen species. In present study we aimed to evaluate erythrocyte reduced glutathione (GSH) levels as an antioxidant and erythrocyte malondialdehyde (MDA) as a marker of lipid peroxidation. The study included twenty-five Visceral leishmaniasis patients and they were followed up after their complete chemotherapy with antileishmanial drugs (sodium stibogluconate) for 30 days. Forty six age and sex matched healthy individuals were taken as controls. GSH levels in erythrocytes of visceral leishmaniasis patients were increased in spite of significant increased erythrocyte MDA as compared to controls. Whereas erythrocyte GSH and MDA levels of follow up patients were decreased as compared to patients before treatment groups. We concluded that visceral leishmaniasis patients are in oxidative stress which most likely induces the endogenous antioxidant such as GSH or its poor utilization by cells.

Abstract
Three diagnostic tests for visceral leishmaniasis (VL), the freeze-dried direct agglutination test (FD-DAT), the rK39 dipstick and a urine latex antigen test (KAtex), were evaluated for use in primary care in East Africa and the Indian subcontinent. Clinical suspects were prospectively recruited and tissue, blood and urine samples were taken. Direct microscopic examination of tissue smear, and FD-DAT, rK39 and KAtex were performed. Sensitivity and specificity with 95% credible intervals were estimated using Bayesian latent class analysis. On the Indian subcontinent both the FD-DAT and the rK39 strip test exceeded the 95% sensitivity and 90% specificity target, but not so in East Africa. Sensitivity of the FD-DAT was high in Ethiopia and Kenya but lower in Sudan, while its specificity was below 90% in Kenya. Sensitivity of the rK39 was below 80% in the three countries, and its specificity was only 70% in Ethiopia. KAtex showed moderate to very low sensitivity in all countries. FD-DAT and rK39 can be recommended for clinical practice on the Indian subcontinent. In East Africa, their clinical use should be carefully monitored. More work is needed to improve existing formats, and to develop better VL diagnostics.

Abstract
Visceral leishmaniasis (VL) affects persons from the lowest socioeconomic strata of the community, but its economic impact is not precisely known. An exploratory survey to document the economic costs of VL to households was conducted in an endemic focus in eastern Nepal. Data were collected from the 20 households in this cluster. Cases of VL over the last 3 years were elicited and information on direct and indirect costs incurred due to the disease as well as income of the households over the last year was estimated. It was reported that 15.0% (16/107) of the residents had suffered from VL and that almost all of the patients had preferred, in the first instance, to visit the private services or local faith healers instead of visiting the local public health facility. Average total costs incurred per episode of VL were above the median annual per capita income, and six of the seven affected households either had to sell part of their livestock or to take a loan to cover the costs. Direct costs consisted of 53% of the total cost, with 75% of this cost incurred before the patients actually received any treatment for VL. This study demonstrates how VL can lead to catastrophic expenditure for affected households.

Abstract
The protozoan parasite Leishmania belongs to the most ancient eukaryotic lineages and this is reflected in several distinctive biological features, such as eukaryotic polycistronic transcription and RNA trans-splicing. The disclosure of this organism's unusual characteristics leads to a better understanding of the origin and nature of fundamental biological processes in eukaryotes. Here we report another unusual phenomenon as we demonstrate that precursor ribosomal RNA can be extensively polyadenylated during post-transcriptional processingt. Furthermore, we demonstrate that the degree of precursor rRNA polyadenylation is variable in different strains and in the different life-stages of a strain.

Abstract
Spinal tuberculosis is usually secondary to lung or abdominal involvement and may also be the first manifestation of tuberculosis. Spinal tuberculosis (often called Pott's disease) is by definition, an advanced disease, requiring meticulous assessment and aggressive systemic therapy. Physicians should keep the diagnosis in mind, especially in a patient from a group with a high rate of tuberculosis infection. This review aims on updating the knowledge on spinal tuberculosis and its management. Skeletal involvement has been reported to occur in approximately 10% of all patents with extrapulmonary tuberculosis, and half of these patients develop infection within the spinal column. Symptoms of spinal tuberculosis are back pain, weakness, weight loss, fever, fatigue, and malaise. It is much more prone to develop neurological manifestation, paraplegia of varying degree. The palpation of spinous process in routine clinical examination is the most rewarding clinical method and is an invaluable measure for early recognition. Diagnosis of spinal tuberculosis is made on the basis of typical clinical presentation along with systemic constitutional manifestation and the evidence of past exposure to tuberculosis or concomitant visceral tuberculosis. Magnetic resonance imaging can define the extent of abscess formation and spinal cord compression. The diagnosis is confirmed through percutaneous or open biopsy of the spinal lesion. Surgery is necessary as an adjunct to antibiotic therapy if the vertebral infection produces an abscess, vertebral collapse, or neurologic compression. Some patents need aggressive supportive care owing to tuberculous meningitis or encephalopathy. Moreover, the importance of immediate commencement of appropriate treatment and its continuation for adequate duration along with the proper counseling of the patient and family members should not be underestimated for successful and desired outcome.

Abstract
Sodium stibogluconate (SSG) is the first-line therapy for visceral leishmaniasis (VL) in south-eastern Nepal. Recent studies from the neighbouring state of Bihar, India, have shown a dramatic fall in cure rates with treatment failure occurring in up to 65% of VL patients treated with SSG. A prospective study was conducted at a tertiary-level hospital located in south-eastern Nepal from July 1999 to January 2001. Parasitologically proven kala-azar patients with no previous history of treatment for VL were treated with SSG 20 mg/kg/d for 30 d which was extended to 40 d in those with persistent positive parasitology. Of the 110 patients who completed SSG therapy and were assessed at 1 and 6 months, definite cure was achieved in 99 patients (90%) and SSG failure occurred in 11 patients (10%). Except for the presence of hepatomegaly and a lower platelet count there was no clinical or laboratory baseline characteristic associated with treatment failure. A significantly lower cure rate (76%, P = 0.03) was observed in patients from the district of Saptari, which borders the antimony-resistant VL areas of Bihar. The efficacy of SSG as a first-line treatment for VL in south-eastern Nepal was still satisfactory, except for the patients living closer to the antimony-resistant VL areas of India. These findings indicate that the spread of resistance to antimonials is already taking place in Nepal and that a policy to control further spread should be urgently implemented.

Abstract
BACKGROUND We evaluated the diagnostic accuracy as well as the reproducibility of the urine latex agglutination test 'KAtex' in the diagnosis of kala-azar in patients recruited at a tertiary care centre in Dharan, Nepal, between November 2000 and January 2002. METHODS All patients presenting with fever of 2 weeks or more and splenomegaly were consecutively enrolled. Bone marrow and--if negative--spleen aspirates were examined for Leishmania donovani. Serum and urine samples were taken in duplicate for the Direct Agglutination Test (DAT) and KAtex. The reference laboratory determined sensitivity and specificity of KAtex. Reproducibility between both laboratories was assessed. RESULTS KAtex was performed on urine from 155 parasitologically confirmed kala-azar and 77 non-kala-azar cases (parasitology and DAT-negative). KAtex showed a sensitivity of 47.7% (74/155, 95% CI: 39.7-55.9) and a specificity of 98.7% (76/77, 95% CI: 93.0-100.0). Reproducibility of KAtex showed a kappa of 0.684 (P < 0.001, n = 232). CONCLUSION KAtex evaluation showed high specificity, low sensitivity and moderate reproducibility. A urine test for kala-azar could become a real breakthrough in kala-azar management if its reproducibility and sensitivity could be further improved.

Abstract
Tuberculosis is a common disease and its incidence is in rising tendency in developed world because of AIDSand transglobal migration. Abdominal tuberculosis is more common in immunocompromised populationand manifests as infection of peritoneum, hollow or solid abdominal organs and abdominal lymphatics withmycobacterium tuberculosis organism. The peritoneum and ileo-cecal region are the most likely sites ofinfection and are involved in the majority of cases by hematogenous spread or through swallowing of infectedsputum from primary pulmonary tuberculosis. Pulmonary tuberculosis is evident in less than half of patientseither in active or latent form. Abdominal tuberculosis has a protean manifestation although the mostcommon clinical feature is the triad of abdominal pain, fever and weight loss. The diagnosis is often delayedbecause of non-specific presentation and is usually made through a combination of radiologic, microbiologic,histopathologic, endoscopic and molecular techniques. None of them provide a gold standard by themselves.However, an algorithm of these diagnostic methods leads to considerably higher precision in the diagnosisof abdominal tuberculosis which primarily necessitates a clinical awareness of this serious health problem.Abdominal tuberculosis is a serious condition and if untreated outcome is fatal. Early diagnosis and immediateinitiation of treatment along with dietary support is crucial for better outcome. Antimicrobial treatment isthe same as for pulmonary tuberculosis and management often requires combination of antituberculardrugs and surgery – for diagnosis as well as therapy.Key Words: Tuberculosis; Abdominal Tuberculosis; Extrapulmonary Tuberculosis.

Abstract
The clinical presentations of severe and complicated malaria vary. The prognosis is poor when associatedwith cerebral malaria and acute renal failure. Clinical profile, biochemical parameters and outcome werestudied in 46 adult patients of malaria admitted in a tertiary care hospital between April 2002 to April2003. The age of the patients ranged from 15 to 60 years. Majority (n=30) of the patients were in age groupof 15 to 34 years. 67% of the patients were from terai belt. Mean duration of febrile illness was 10 days atthe time of presentation. 39% (n=18) patients had hepatic dysfunction and 22% (n=10) had acute renalfailure (ARF) according to WHO criteria. All patients with ARF were oligo-anuric and required dialysissupport. Four patients died of which three were patients with ARF and hepatic dysfunction. Althoughmalaria still remains a major health problem, malarial renal disease has not been formally reported previouslyfrom Nepal. Early initiation of antimalarial therapy, close observation for organ failure and early initiationof dialysis in ARF is instrumental in the recovery of the patient.Key Words: Malaria, Organ Failure.

Abstract
Between April 9 and May 5 2000, an outbreak of fatal cardiotoxicity occurred in Nepal amongst visceral leishmaniasis patients treated with a recently introduced batch of generic sodium stibogluconate (SSG) from GL Pharmaceuticals, Calcutta, India. Eight (36%) of 23 patients treated with this batch died, and in 5 (23%) death was attributed to the cardiotoxicity of the drug. This contrasts with the low total death rate (3.2%) and death rate due to cardiotoxicity (0.8%) observed among 252 patients treated between August 1999 and December 2001 with generic SSG from Albert David Ltd, Calcutta, India. These data show that every batch of generic SSG should be subject to rigorous quality control prior to use.

Abstract
Currently there are no effective orally administered drugs or visceral leishmaniasis or kala-azar, a parasitic disease affecting about 0.5 million people a year, majority of whom are in India and adjacent areas of Nepal. Symptoms of affected patients are fever, cachexia, hepatosplenomegaly and pancytopenia. The disease is usually fatal, if left untreated. Traditionally kala-azar is treated with four weeks of injections of sodium stibogluconate, a pentavalent antimonial. However, this treatment has not only shown resistance in 37-64% patients of the current Indian epidemic in Bihar (the epicentrre) but also life-threatening cardiotoxicity in 7-10% and treatment-related deaths in 5-10% cases, besides being unsuccessful at times. Parenteral amphotericin B is used as a secondary agent that shows 95% effectiveness but its toxicity and high cost of even the well tolerated liposomal complex precludes its wide use in the developing countries, where the disease is present in epidemic proportions. Recently, miltefosine (hexadecylphosphocholine), a compound originally developed as an antitumour agent has been shown to be an orally effective drugs against kala-azar. All clinical trials with this drug are conducted in India in patients of visceral leishmaniasis. A regimen of 100 mg per day or 50 mg twice daily for 3-4 weeks was observed to produce a cure rate of 100%. Gastrointestinal side effects were frequent (62%) but no patient discontinued the therapy. A phase III trial involving 300 HIV-negative adults and adolescents is underway in India and the drug is hoped to be licensed in the next 2-3 years. Few studies of phase II clinical trials mainly conducted in Kenya with another drug, sitamaquine or kalazaquine (WR 6026), an 8-aminoquinoline has also shown promise as an orally effective agent (in a dose of 1 mg/kg/day for two weeks) for visceral leishmaniasis. These Studies with two orally effective compounds, it appears, will open new vistas for orally effective, affordable and acceptable drugs in the armamentarium for the treatment of kala-azar. It is expected that in future we would have effective ways to prevent and treat all forms of leishmaniasis without discomforting the patient.

Abstract
The diagnosis of visceral leishmaniasis (kala-azar) remains difficult in rural endemic areas and practical and reliable tests are badly needed. Two serological tests, the Direct Agglutination Test (DAT) and an rK39-antigen-based dipstick test, were compared to parasitological diagnosis in a group of 184 patients presenting at a tertiary care centre in south-eastern Nepal with a history of fever > or = 14 days and splenomegaly; 139 patients had a parasitologically proven kala-azar and 45 patients had a negative parasitological work-up. The rK39 dipstick showed a sensitivity of 97% and a specificity of 71%. The DAT was up to 99% sensitive with a low cut-off titre (1:400) but its specificity did not exceed 82% even with a high cut-off titre (1:51 200). Both tests could be used for screening suspect patients in endemic areas. However, their use as confirmatory tests should be restricted to situations where the proportion of kala-azar among clinical suspect patients is high. The rK39 dipstick is cheaper and easier to use than the DAT and could be used widely provided that both its performance and production remain stable.
