Abstract
INTRODUCTION Snakebite envenomation poses a significant health risk, particularly in low-resource settings where access to proper treatment is limited. CASE PRESENTATION This study reports two cases of Russell's viper bites in rural Bangladesh, involving 48 and 35-year-old Bangladesh males, respectively, and highlights the difficulties in providing adequate medical care and in treating any complications that may arise. Both cases involved delayed access to healthcare, initial visit to traditional healers, and the development of severe complications such as coagulopathy, renal failure. After the intervention both cases survived which is scarce in low resource settings. CONCLUSION The cases underscore the importance of early recognition, appropriate management, and improved healthcare infrastructure to optimize survival outcomes in snakebite cases in resource-limited settings. These cases will contribute valuable insights to the field of snakebite management and provide guidance for improving survival rates and outcomes among snakebite victims in Bangladesh.

Abstract
Around two million people are engaged in marine fishing in the Bay of Bengal. Bites by sea snakes were common hazards feared by millions fishing at sea in earlier days. Current morbidity and mortality are also not known. This study was conducted to document and describe sea snake bites among selected communities of sea-going fishermen in Bangladesh. A questionnaire-based cross-sectional survey was conducted from May to October 2019 among three communities of sea-going fishermen living along the coast of the Bay of Bengal in Cox's Bazar district. Fishermen were first asked by trained interviewers to recall any sea snakebites to themselves and among their fellows on board within the last year, then within the last 5 years and at any time before that. For any bite, related information including outcome was noted. Overall, 25.4% of respondents (62 out of 244) had been bitten by sea-snakes. Mean age was 37.6(±14) years; all males. 51.6% received some sort of treatment locally; 71% hot compress and 48% tourniquets. In 80.6% the affected limb was not immobilized. The bitten site was incised in 29%. 22.6% received treatment from traditional healers, 48.4% from local hospitals, 29% from district hospital. Six victims (9.7%) suffered from severe life-threatening consequences of the sea snakebite but none died. 32% of the fishermen had seen the offending snake. Sea snakebites are potentially dangerous; therefore, educating fishermen to avoid contact with sea snakes would dramatically reduce the incidence of sea snakebites. Most bites are treated initially by local measures which are often not scientific. Provision of proper first aid and treatment might reduce mortality and morbidity. A larger survey on sea snake bites among the fishermen in all coastal areas of Bangladesh is needed to determine the nationwide burden of morbidity and mortality related to sea snakebite.

Abstract
Severe developmental disability in children affects the life of the child and entire household. We conducted a qualitative study to understand how caregivers manage severe developmental disabilities in children in rural Africa. Families and six children (out of 15 children) who had serious permanent sequelae from a cerebral infection in Handeni, Tanzania, were contacted and invited to a workshop to recount their experience living with severe developmental disabilities. After consent, individual interviews were conducted first through recording of individual digital stories and then through individual semi-structured interviews. Pre-determined key categories were used to analyse the data. Our results showed that developmental disabilities required constant care and reduced the autonomy of the children. Schooling had not been attempted or was halted because of learning problems or inability to meet specialized school costs. Parents were under constant physical, emotional and financial stress. Their occupational earnings decreased. Some families sold their assets to survive. Others began to rely on relatives. Understanding the consequences of developmental disability helps to identify where social support should be focused and improved.

Abstract
Access to safe, effective, quality-assured antivenom products that are tailored to endemic venomous snake species is a crucial component of recent coordinated efforts to reduce the global burden of snakebite envenoming. Multiple access barriers may affect the journey of antivenoms from manufacturers to the bedsides of patients. Our review describes the antivenom ecosystem at different levels and identifies solutions to overcome these challenges. At the global level, there is insufficient manufacturing output to meet clinical needs, notably for antivenoms intended for use in regions with a scarcity of producers. At national level, variable funding and deficient regulation of certain antivenom markets can lead to the procurement of substandard antivenom. This is particularly true when producers fail to seek registration of their products in the countries where they should be used, or where weak assessment frameworks allow registration without local clinical evaluation. Out-of-pocket expenses by snakebite victims are often the main source of financing antivenoms, which results in the underuse or under-dosing of antivenoms, and a preference for low-cost products regardless of efficacy. In resource-constrained rural areas, where the majority of victims are bitten, supply of antivenom in peripheral health facilities is often unreliable. Misconceptions about treatment of snakebite envenoming are common, further reducing demand for antivenom and exacerbating delays in reaching facilities equipped for antivenom use. Multifaceted interventions are needed to improve antivenom access in resource-limited settings. Particular attention should be paid to the comprehensive list of actions proposed within the WHO Strategy for Prevention and Control of Snakebite Envenoming.

Abstract
Bangladesh is one of the top-ten most heavily burdened countries for viral hepatitis, with hepatitis B (HBV) infections responsible for the majority of cases. Recombinant and occult HBV infections (OBI) have been reported previously in the region. We investigated an adult fever cohort (n=201) recruited in Dhaka, to determine the prevalence of HBV and OBI. A target-enrichment deep sequencing pipeline was applied to samples with HBV DNA >3.0 log10 IU ml−1. HBV infection was present in 16/201 (8 %), among whom 3/16 (19 %) were defined as OBI (HBsAg-negative but detectable HBV DNA). Whole genome deep sequences (WGS) were obtained for four cases, identifying genotypes A, C and D. One OBI case had sufficient DNA for sequencing, revealing multiple polymorphisms in the surface gene that may contribute to the occult phenotype. We identified mutations associated with nucleos(t)ide analogue resistance in 3/4 samples sequenced, although the clinical significance in this cohort is unknown. The high prevalence of HBV in this setting illustrates the importance of opportunistic clinical screening and DNA testing of transfusion products to minimise OBI transmission. WGS can inform understanding of diverse disease phenotypes, supporting progress towards international targets for HBV elimination.

Abstract
BACKGROUND In 2017 hundreds of thousands of 'Rohingya' fled to camps for Forcefully Displaced Myanmar Nationals (FDMN) in Cox's Bazar, Bangladesh. OBJECTIVE To describe the FDMNs presenting for care at public health facilities in Bangladesh so as to understand the health problems faced by the FDMNs and the burden on these public health facilities. METHODS This study combined a retrospective review of existing hospital and clinic data with prospective surveillance in government health care centres. FINDINGS The retrospective data showed a 26% increase in the number of consultations at the Kutupalong community clinic, the primary health facility closest to the camps, from 19,567 in 2015 to 26,309 in 2019. There was a corresponding 11% increase in admissions to health facilities in the area, from 80,991 in 2017 to 91,424 in 2019. Prospective surveillance of 9,421 FDMNs seeking health care from July 2018 to December 2019 showed that 29% had an infectious disease, 20% nutritional problems, 12% pregnancy-related conditions and 7% trauma or injury. CONCLUSIONS Great uncertainty remains regarding the return of FDMN to their home country of Myanmar. The current on-going protests following the military coup adds further insecurity to the status of the Rohingya. The presence of a large migrant population relative to a smaller host community burdens the limited facilities and resources of the public health sector. Continued support by the international public health community and civil society organizations is needed.

Abstract
Trichosporon asahii is a yeast-like fungus that is emerging as an important cause of invasive infections in tertiary medical centres. A 58-year-old Chinese man with no known medical illnesses presented with liver lacerations and multiple fractures following an alleged 12-foot fall at a construction site. The gravity of his injuries and poor haemodynamic status necessitated an intensive care unit (ICU) admission, during which several febrile episodes were detected and multiple antibiotics were administered. After being in the ICU for at least two weeks, a urease-positive yeast was isolated from the patient's blood. The yeast formed dry, fuzzy and wrinkled white colonies on Sabouraud dextrose agar following prolonged incubation, and produced blastoconidia, true hyphae, pseudohyphae and arthroconidia on slide culture. It was identified biochemically by the ID 32 C kit as T. asahii. The yeast had elevated minimal inhibitory concentration (MIC) values to fluconazole, amphotericin B, flucytosine and all echinocandins tested. In view of this, the patient was treated with voriconazole and was successfully transferred to the general medical ward.

Abstract
Post Kala-azar Dermal Leishmaniasis (PKDL) is the sequel of visceral leishmaniasis in Indian subcontinent and may appear among patients with or without previous history of visceral leishmaniasis (VL). The aim of the study is to understand the male reproductive safety profile of miltefosine used for the treatment of Post Kala-azar Dermal Leishmaniasis (PKDL) in Bangladesh. From January 2017 to March 2017, an exploratory study was carried out on male fertility capacity in Bangladesh among male patients above 14 years old with PKDL treated with miltefosine. Twenty nine male patients were included to observe the effect of miltefosine on reproductive health. All PKDL patients had history of visceral leishmaniasis (VL) in different time periods. Among them three (10.3%) patients were unable to ejaculate semen. In semen analysis, 3 patients (10.3%) were found azoospermia (sperm count & motility- 0, viscosity- good, pH- 7 to 8), microscopically there was presence of RBC (5-15/HPF), WBC (8-15/HPF). Another 3 patients (10.3%) were found oligospermia (sperm count- 4.2 to 15.3 million/ml, motility- 20 to 50%, viscosity- good, pH- 6 to 9, RBC- 4 to 15/HPF, WBC- 4 to 15/HPF). The study documented some important findings in evaluating male infertility and selection of drug regimens in treating PKDL patients with miltefosine for 12 weeks.

Abstract
Background: Chronic Obstructive Pulmonary Disease (COPD) is of public health importance. Indoor biomass (wood, cowdung etc) smoke exposure from cooking is associated with respiratory conditions and may predispose to COPD. The objective of this study was to evaluate the risk of biomass smoke exposure and COPD.Methods: A cross sectional study was conducted at a rural setting of Bangladesh. Rural women over 40 years and exposed to biomass fuel, liquid petroleum gas or natural gas smoke were evaluated using a questionnaire and their lung function was assessed using a portable spirometry.Results: The overall prevalence of COPD in the rural women was 20.4%. It was significantly higher in women using biomass fuel for cooking than in those using natural gas/LPG (p<0.001). Biomass smoke exposure was found significantly associated with COPD (OR= 3.385, CI=1.60-7.13, p<0.05). Lung function was significantly reduced (p<0.05) among women who were using biomass than those using natural gas/LPG.Conclusion: Biomass fuel smoke exposure is a risk factor for development of COPD.Chatt Shi Hosp Med Coll J; Vol.15 (1); Jan 2016; Page 8-11

Abstract
Injuries are a focus of public health practice because they pose a serious health threat, occur frequently and are preventable. The evidence regarding injury, its contributing factor and its consequence in rural population of Bangladesh is scarce. Present study aimed to assess the epidemiology of injury in a rural area. The study was conducted in the 'Bairag' Union of Anwara upazilla in Chittagong district of Bangladesh. Data of 6256 individuals were collected from 1016 households. Three structured and standardized questionnaires were used for data collection. The questionnaires were pretested and validated prior to final survey. Severity of injury was assessed based on the number of days with restricted activity and consequences of injury were considered as a measure of severity of injury. A total of six people died due to injury in last one year in the survey, the death tolls to 0.096% (95% CI 0.037%-0.199%). A total of 392 experienced an injury that at least hampered one day's routine activity. Crude prevalence of injury over last one year is calculated to be 6.27% (95% CI 5.69%-6.89%). Of injured subject's majority (77.2%) were aged between 10 to 59 years, 73% were male, 55.6% were of lower class and among them 7.9 % suffered multiple injuries. More than 80% of the incident leading to injury happened during the day, (8 am to 6 pm). Daytime injury mostly occurs in afternoon. The mechanism of injury of 30% subjects were road accident, of 29.5% subjects was slip, trip or fall. In 17.9% victims' mechanism of injury was collision with a person or object. Around 10% had deep cut, 1.4% had superficial cut, and 3.3% patient had burn through contact with heat. Among the injured only 19.2% escaped any physical consequence, 27.2% suffered from decrease in work capacity, 48.1% developed temporary disability, 3.8% developed permanent disability, and 1.2% suffered disfiguration.

Abstract
Background In visceral leishmaniasis (VL), retinal changes have previously been noted but not described in detail and their clinical and pathological significance are unknown. A prospective observational study was undertaken in Mymensingh, Bangladesh aiming to describe in detail visible changes in the retina in unselected patients with VL. Methods Patients underwent assessment of visual function, indirect and direct ophthalmoscopy and portable retinal photography. The photographs were assessed by masked observers including assessment for vessel tortuosity using a semi-automated system. Results 30 patients with VL were enrolled, of whom 6 (20%) had abnormalities. These included 5 with focal retinal whitening, 2 with cotton wool spots, 2 with haemorrhages, as well as increased vessel tortuosity. Visual function was preserved. Conclusions These changes suggest a previously unrecognized retinal vasculopathy. An inflammatory aetiology is plausible such as a subclinical retinal vasculitis, possibly with altered local microvascular autoregulation, and warrants further investigation.

Abstract
National Malaria Control Program (NMCP) of Bangladesh has introduced Artemisinin Based Combination (ACT), Coartem(R) (Artemether-Lumefantrine (AL), fixed dose combination, in the confirmed cases of uncomplicated P. falciparum malaria since 2004. Despite the reduction of mortality due to malaria, the development and spread of anti-malarial drug resistance wordwide posing a threat to the health services and will make it difficult to control malaria in Bangladesh in future. We need to have an alternative to Coartem which could be Artesunate-amodiaquine (AA) in a fixed dose combination (FDC), a cheaper altenative not yet evidenced to be effective and safe to our population. In this study we compared the efficacy and safety of Artemether + Lumefantrene (FDC, Coartem®) with Artesunate +Amodiaquine tablets (100/270 mg FDC) for the treatment of uncomplicated P. falciparum malaria in three high risk multi-drug resistant malaria prevalent areas of Bangladesh. It was an open label randomized controlled trial conducted between December 2008 and November 2009 in 4 upazillas in patients over the age 12 to 60 years diagnosed as a case of uncomplicated P.falciparum malaria. The outcome of the cases were measured as clinical response, parasitological response, defervescence time and parasite clearance time. Drug safety was assessed by comparing the adverse events. A total of 252 cases were randomized to receive Artesunate + Amodiaquine (AA group, 147 cases) and Artemether + Lumefantrene (AL group, 106 cases), one lost to follow up at day 28 in AA group. The distribution of the cases was comparable by age, sex and study sites. Treatment success response was observed 100% in the AL group and AA group had 99%, two failures with AA were late treatment failures and the difference was not statistically significant (p>.1). The parasitological sensitive (S) response was observed in 97% of cases in AL group and 95% in the AA group, and was not a statistically significant difference. There was no significant difference in deffervescence time and parasite clearance time between two groups of cases. No serious adverse events were observed. The frequencies of minor adverse events were insignificantly different between the two treatment groups. The two ACT regimen, AA and AL had no significant difference in efficacy and safety for treatment of Uncomplicated Malaria in Bangladesh. However, there were few more failures with AA regimen compared to AL regimen, which was not statistically significant. Both these regimens can be used alternatively by the NMCP of Bangladesh as first-line treatment option.

Abstract
A cross sectional analysis of chest radiograph was performed in 100 patients with tuberculosis to observe the recent trends of radiographic presentation. The study was done from April to December, 2009, in Sir Salimullah Medical College and Mitford Hospital, Dhaka, Bangladesh. The chest x-ray findings were analyzed and zonal involvement and pattern of opacities were categorized and compared. Majority of patients (45%) showed involvement of the upper zone. Dominating lesion was consolidation (25%). Most of the patients were between 15-40 years. Forty-four percent patients were sputum positive for Acid Fast Bacilli and cavitation was the dominant lesion among them. Chest x-ray of patients with post primary tuberculosis shows involvement predominantly in the upper zone of lung. The most common opacity was consolidation. This correlates with different studies done over different population.

Abstract
Adenosine De Aminase (ADA) is increased in tuberculous ascitic fluid due to the stimulation of T-cells by mycobacterial antigens. The treatment for abdominal tuberculosis including ascites as a presentation is a matter of controversy around the world. The study is aim at to see the outcome of antitubercular chemotherapy in selected tubercular ascites patients. This hospital based prospective study was done in 24 cases of adult (>13 years) tubercular ascites admitted in a tertiary hospital Dhaka, over one year. Increased ADA level (>37iu/L) in ascitic fluid evaluated after the colorimetric method of Galanti and Giusti and other supportive investigations were done for diagnosing tuberculosis. Patients were under treatment of ATT cat-1 for six months as per national guide line. Outcome was seen as predefined criteria as treatment completed, cured, improved and not improved. Total number of patient is 24. Of which range of age is 13-70 years and mean±SD (33.2±14.77) with male female ratio is 0.85:1. Ninety six percent patients presented with abdominal pain, 23(96%) with fever, 22 (91%) with anorexia. Abdominal tenderness in 22(91%), ascites on 24(100%), hepatomegaly on 2(8%). Hundred percent patients were evaluated after completion of treatment. Twenty three (96%) patients improved and 1(4%) not improved. There is effectiveness of standard chemotherapy suggested by national guideline. Outcome of the patients were highly satisfactory with short regimen of antitubercular chemotherapy.

Abstract
Infection with Burkholderia pseudomallei has been described, albeit rarely, patients in Bangladesh. Infection usually follows percutaneous inoculation or inhalation of the causative bacterium, which is present in soil and surface water in the endemic region. A 35-year-young male farmer presented with prolonged fever and significant weight loss. Patient gradually deteriorated despite getting different antibiotics including intravenous ceftriaxone and metronidazole. Panels of investigations were done which revealed no diagnostic confirmation except uncontrolled diabetes and multiple abscesses in different organs. Melioidosis was suspected and serum samples were positive for Burkholderia pseudomallei antibody. The case illustrates the importance of non-specific nature of the clinical presentation and high index of suspicion of uncommon diseases like melioidosis where the disease has not been considered as an endemic.

Abstract
BACKGROUND Acute organophosphorus (OP) poisoning is relatively common and a major cause of death from poisoning in developing countries. Magnesium has been shown to be of benefit in animal models. METHODS We conducted a phase II study of bolus doses of (MgSO4) in 50 patients with acute organophosphate poisoning. Patients eligible for inclusion had ingested OP and had cholinergic symptoms consistent with moderate or severe poisoning. All patients received standard care of atropinization titrated to control muscarinic symptoms and pralidoxime. The trial was run in 4 sequential groups of patients. Participants in each group received a different total dose of MgSO4 (20%) administered as intermittent bolus doses infused over 10-15 min or placebo. There was one control patient for every 4 patients who received MgSO4. Group A (16 patients) received a total of 4 gm MgSO4 as a single bolus, group B (8 patients) received 8 gm (in two 4 gm doses q4H), group C (8 patients) received 12 gm (in three 4 gm doses q4H) group D (8 patients) received 16 gm (in four 4 gm doses q4H) and control (10 patients) received placebo). Patients were closely monitored for any adverse reaction like significant clinical neuromuscular disturbance and respiratory depression. RESULTS No adverse reactions to magnesium were observed. The 24 hour urinary magnesium concentration were statistically different between 16 gm (234.74 ± 74.18 mg/dl) and control (118.06 ± 30.76 mg/dl) (p = 0.019), while it was much lower than the 80% of the intravenous magnesium load. Six patients died in control group compared to 3 in 4 gm, 2 in 8 gm and 1 in 12 gm group. There was no mortality in 16 gm group. CONCLUSION Magnesium was well tolerated in this study. Larger studies are required to examine for efficacy.

Abstract
We conducted a study of the knowledge, attitudes and practices regarding dog bites among residents of a rural community in Bangladesh from September 2006 to February 2007 using face to face interviews with 1,973 adults from five villages. The mean age of the respondents was 34+/-16 years. Sixty-eight percent of subjects were female, 7.3% of respondents reported a history of dog bite in a family member; 10% had been bitten twice. Sixty-five percent of subjects were aware of rabies and 99.1% knew a dog bite was the cause of rabies. Seventy-one percent of subjects were aware of a rabies vaccine, 77.5% of respondents stated rabies can cause death. Ninty percent of dog bite victims received treatment by traditional healers, 25% were treated with a rabies vaccine and 2.1% of victims died. Greater awareness is needed in rural Bangladesh regarding prevention of rabies.

Abstract
Severe organophosphate compound (OPC) poisoning is an important clinical problem in many countries of the world. Unfortunately, little clinical research has been performed and little evidence exists with which to determine the best therapy. A study was therefore undertaken to determine the optimal dosing regimen for atropine in the treatment of OPC poisoning. An open-label randomized clinical trial was conducted in Chittagong Medical College Hospital, Chittagong, Bangladesh, on 156 hospitalized individuals with OPC poisoning from June to September 2006. The aim was to compare the efficacy and safety of conventional bolus doses with individualized incremental doses of atropine for atropinization followed by continuous atropine infusion for management of OPC poisoning. Inclusion criteria were patients with a clear history of OPC poisoning with clear clinical signs of toxicity, i.e. features of cholinergic crisis. The patients were observed for at least 96 h. Immediate outcome and complications were recorded. Out of 156 patients, 81 patients received conventional bolus dose atropine (group A) and 75 patients received rapidly incremental doses of atropine followed by infusion (group B). The mortality in group 'A' was 22.5% (18/80) and in group 'B' 8% (6/75) (p < 0.05). The mean duration of atropinization in group 'A' was 151.74 min compared to 23.90 min for group 'B' (p < 0.001). More patients in group A experienced atropine toxicity than in group 'B' (28.4% versus 12.0%, p < 0.05); intermediate syndrome was more common in group 'A' than in group 'B' (13.6% versus 4%, p < 0.05), and respiratory support was required more often for patients in group 'A' than in group 'B' (24.7% versus 8%, p < 0.05). Rapid incremental dose atropinization followed by atropine infusion reduces mortality and morbidity from OPC poisoning and shortens the length of hospital stay and recovery. Incremental atropine and infusion should become the treatment of choice for OPC poisoning. Given the paucity of existing evidence, further clinical studies should be performed to determine the optimal dosing regimen of atropine that most rapidly and safely achieves atropinization in these patients.

Abstract
There was an outbreak of new emergence viral encephalitis caused by Nipah virus among humans in some areas of Bangladesh during 2001 - till to date. The disease affected mainly the young, had increased suspicion to spread from bat to man through eating of the same fruits. The risk of human-to-human transmission is thought to be low though many of the affected individuals belonged to the same family. The disease presented mainly as acute encephalitis with usually a short incubation period of less than two weeks, with the main symptoms of fever, headache, and giddiness followed by coma. Distinctive clinical signs include areflexia, hypotonia, hypertension, tachycardia and segmental myoclonus. Serology was helpful in confirming the diagnosis. Magnetic resonance imaging (MRI) showed distinctive changes of multiple, discrete or confluent small high signal lesions, best seen with fluid-attenuated inversion recovery (FLAIR) sequences. Mortality was as high as 32-92% and death was probably due to severe brainstem involvement. Relapse encephalitis was seen in those who recovered from acute encephalitis, and late-onset encephalitis was seen in those with initial non-encephalitic or asymptomatic diseases. Both these manifested as focal encephalitis arising from recurrent infection.

Abstract
The present study aims to assess the different types of costs for treatment of snake bite patients, to quantify household economic impact and to understand the coping mechanisms required to cover the costs for snake bite patients in Bangladesh. The patients admitted to four tertiary level hospitals in Bangladesh were interviewed using structured questionnaires including health-care-related expenditures and the way in which the expenditures were covered. Of the snakes which bit the patients, 54.2% were non-venomous, 45.8% were venomous and 42.2% of the patients were given polyvalent antivenom. The total expenditure related to snake bite varies from US$4 (US$1 = Taka 72) to US$2294 with a mean of US$124 and the mean income loss was US$93. Expenditure for venomous snake bite was US$231, which is about seven times higher than non-venomous snake bite (US$34). The treatment imposes a major economic burden on affected families, especially in venomous snake bite cases.

Abstract
The present study describes the ethnobotanical, phytochemical, and toxicological evaluations of Xanthium strumarium L. growing in Bangladesh. In toxicity evaluation on rats, the methanol extract of seedlings showed mortality, while both seedling and mature plant extracts raised the serum alanine transaminase and aspartate transaminase values and produced significant abnormalities in the histopathology of liver and kidney of rats. On the other hand, the aqueous soluble fraction of methanol extract of mature plant (LC50 = 0.352 microg/mL) and methanol crude extract of seedlings (LC50 = 0.656 microg/mL) demonstrated significant toxicity in the brine shrimp lethality bioassay. A total of four compounds were purified and characterized as stigmasterol (1), 11-hydroxy-11-carboxy-4-oxo-1(5),2(Z)-xanthadien-12,8-olide (2), daucosterol (3) and lasidiol-10-anisate (4). The present study suggests that X. strumarium is toxic to animal.

Abstract
The neurological findings of 100 patients of adult cerebral malaria were studied. The commonest neurological feature was symmetrical upper motor neuron lesion as evidenced by exaggerated tendon reflexes and bilateral planter extensor (61%). Twenty two percent had features of meningeal irritation and/or meningism. Abnormal posturing occurred decerebrate rigidity (6%) and decorticate rigidity (4%) with or without opisthotonus, focal neurological deficit was noted in 5% cases. Pupillary size and reaction were normal in 86%, poor in 14%. Corneal reflexes were absent in 4% cases. Fundoscopy showed retinal hemorrhage in 16%, papilloedema is 3% and exudates in 1%. Majority of the patients recovered (80%) without any persistent neurological sequelae at the time of discharge from hospital and death rate was 20%. Patients having focal neurological deficit, disconjugate gaze, poor pupillary reaction, absent corneal reflex and papilloedema were more susceptible to death. Delay in hospitalization and deep coma were also associated with increased mortality, whereas early hospitalization and proper nursing care could reduce mortality.

Abstract
Malaria in Asia is thought to be grossly under-reported and this is evident from previously published statistics from Bangladesh. Malaria screening data from four Upazillas was analysed alongside census data to assess the trends in malaria incidence over time and distribution of malaria by age and gender. Malaria incidence in this area has decreased by around two thirds since 2003, although control measures were not significantly increased until 2005. Malaria occurred in people of all ages with the highest incidence being in young adults. This is consistent with higher occupational exposure in this group. The probability of being screened for malaria decreased with age suggesting significant numbers of adults with malaria may be being missed.

Abstract
BACKGROUND World Health Organization treatment guidelines recommend that adults with severe malaria be admitted to an intensive care unit (ICU). However, ICU facilities are limited in the resource-poor settings where most malaria occurs. Identification of patients at greater risk of complications may facilitate their triage and resource allocation. METHODS With use of data from a trial conducted in Southeast Asia (n=868), a logistic regression model was built to identify independent predictors of mortality among adults with severe malaria. A scoring system based on this model was tested in the original dataset and then validated in 2 series from Bangladesh (n=188) and Vietnam (n=292). RESULTS Acidosis (base deficit) and cerebral malaria (measured as Glasgow Coma Score) were the main independent predictors of outcome. The 5-point Coma Acidosis Malaria (CAM) score was simply derived from these 2 variables. Mortality increased steadily with increasing score. A CAM score <2 predicted survival with a positive predictive value (PPV) of 95.8% (95% confidence interval [CI], 93%- 97.7%). Of the 14 of 331 patients who died with a CAM score <2, 11 (79%) had renal failure and death occurred late after hospital admission (median, 108 h; range, 40-360 h). Substitution of plasma bicarbonate as the measure of acidosis only slightly reduced the prognostic value of the model. Use of respiratory rate was inferior, but a score <2 still predicted survival with a PPV of 92.2% (95% CI, 89.1%-94.7%). CONCLUSIONS Patients with a CAM score <2 at hospital admission may be safely treated in a general ward, provided that renal function can be monitored.

Abstract
A 35-year-old so called snake-expert from Thakurgaon district was admitted in Medicine department of Rangpur Medical College Hospital (RpMCH), Rangpur, Bangladesh on 2nd November 2007 with history of bites by a cobra snake. He was famous for his outstanding works to establish a snake farm first ever in Bangladesh. He had a collection of more than one hundred snakes of different species. He used to hatch eggs of the snakes, feed the young-snakes, collect venoms and sell those. Everyday many visitors used to visit his farm to watch exciting games with poisonous snakes. Several satellite television (TV) channels and some daily newspapers had covered him on different occasions. He was accidentally bitten by a newly caught hungry cobra snake while recording for a satellite TV channel. Following bites he was brought to the hospital three and a half hours later. By that time, neurotoxicity developed. Repeated doses of Anti Snake Venom (ASV) along with respiratory support and other supportive cares were provided. Despite utmost care feasible at RpMCH, patient expired around 49 hours later.

Abstract
This prospective observational clinical study was done to find out the clinical and laboratory parameters of pleural tuberculosis patients, to find out a sensitive and specific tool for diagnosis and to see the effectively of a standard anti-TB regime Isoniazide, Rifampicine, Pyrazinamide, Ethambutol, (2HRZE/4HR) for treatment of pleural tuberculosis in an adult medicine unit, department of Medicine, Chittagong Medical College Hospital, Chittagong, Bangladesh. A series of total thirty-three consecutive pleural tuberculosis patients admitted in that unit over a period of 6 months were enrolled. All thirty-three pleural tuberculosis patients were observed for their demographic and clinical parameters and undergone some relevant investigations like complete blood count, Mantoux test, pleural fluid study and pleural histopathological study. Later on, they were put on anti-tuberculosis therapy without steroid and followed their response after one month. All patients of pleural tuberculosis presented in this medicine unit had fever and cough associated with chest pain (87.9%), dysnoea (42.4%), haemoptysis (9.1%), weight loss (84.4%), anorexia (90.9%). Age of presentation was 34.1+/-16.2 years and of them, 60.7% patients were below 30. Mean Erythrocyte Sedimentation Rate (ESR) was 97.04 mm in 1st hour and 57.6% cases had ESR more than 100. 63.6% had Mantoux Test (MT) positive (>10 mm). Only 6.1% had hemorrhagic effusion and others had straw colored fluid. Mean pleural fluid protein is 5.9 gram/L and sugar 65.7 mg/dl. No Acid Fast Bacilli (AFB) was seen on microscopy in pleural fluid. Pleural biopsy revealed 54.5% granulomatous lesion with or without caseation and another 24.2% shows chronic inflammation. Seventy seven percentage (77%) patients were attended follow-up clinic after 1 month and all patients (100%) were improved with this anti-TB therapy. Of the total patient treated with anti TB drug, 53.5% had no pleural effusion, other had minimum effusion. Only 6.06% require subsequent steroid addition and other measures. Pleural biopsy is the investigations of choice for pleural tuberculosis especially in resource poor countries. Pleural tuberculosis can be treated with a standard anti-TB regime successfully without steroid.

Abstract
We describe a 32-year-old Bangladeshi male presenting with severe malaria caused by a mono-infection with Plasmodium malariae. Rosetting of infected and uninfected erythrocytes, a putative virulence factor in falciparum malaria, was observed in the blood slide. Severe disease caused by P. malariae is extremely rare. The patient made a rapid recovery with intravenous quinine treatment.

Abstract
BACKGROUND Most malaria deaths occur in rural areas. Rapid progression from illness to death can be interrupted by prompt, effective medication. Antimalarial treatment cannot rescue terminally ill patients but could be effective if given earlier. If patients who cannot be treated orally are several hours from facilities for injections, rectal artesunate can be given before referral and acts rapidly on parasites. We investigated whether this intervention reduced mortality and permanent disability. METHODS In Bangladesh, Ghana, and Tanzania, patients with suspected severe malaria who could not be treated orally were allocated randomly to a single artesunate (n=8954) or placebo (n=8872) suppository by taking the next numbered box, then referred to clinics at which injections could be given. Those with antimalarial injections or negative blood smears before randomisation were excluded, leaving 12 068 patients (6072 artesunate, 5996 placebo) for analysis. Primary endpoints were mortality, assessed 7-30 days later, and permanent disability, reassessed periodically. All investigators were masked to group assignment. Analysis was by intention to treat. This study is registered in all three countries, numbers ISRCTN83979018, 46343627, and 76987662. RESULTS Mortality was 154 of 6072 artesunate versus 177 of 5996 placebo (2.5%vs 3.0%, p=0.1). Two versus 13 (0.03%vs 0.22%, p=0.0020) were permanently disabled; total dead or disabled: 156 versus 190 (2.6%vs 3.2%, p=0.0484). There was no reduction in early mortality (56 vs 51 deaths within 6 h; median 2 h). In patients reaching clinic within 6 h (median 3 h), pre-referral artesunate had no significant effect on death after 6 h or permanent disability (71/4450 [1.6%] vs 82/4426 [1.9%], risk ratio 0.86 [95% CI 0.63-1.18], p=0.35). In patients still not in clinic after more than 6 h, however, half were still not there after more than 15 h, and pre-referral rectal artesunate significantly reduced death or permanent disability (29/1566 [1.9%] vs 57/1519 [3.8%], risk ratio 0.49 [95% CI 0.32-0.77], p=0.0013). INTERPRETATION If patients with severe malaria cannot be treated orally and access to injections will take several hours, a single inexpensive artesunate suppository at the time of referral substantially reduces the risk of death or permanent disability.

Abstract
Tuberculous involvement of central nervous system is one of the important health issues causing high mortality and morbidity. Uncertainty and doubt dominate all aspects of CNS tuberculosis. Diagnosis is mainly based on clinical features, cerebrospinal fluid changes, and imaging characteristics. Few studies have shown that corticosteroids improve the clinical outcome, although the precise mechanism of action remains tentative. All the cases were selected on strong clinical suspicion of CNS tuberculosis. They were graded according to tuberculous meningitis (TM) severity grades. In this connection, we studied 13 patients in one medicine unit over 12 month's period to see the effect of corticosteroid as part of the outcome. Nine patients (69.23%) were in grade II, three (23.08%) patients were in grade III, and one (7.69%) was in grade I. Seven patients (53.85%) had tuberculous meningitis and six (46.15%) had tuberculoma (CT or MRI). Out of 13 cases 3 patients (23%) died in the hospital and 10 patients (77%) improved, of whom 2 patients (20%) recovered completely and 8 patients (80%) had residual neurological deficit. Our study suggests that the early detection of CNS tuberculosis is the most important prognostic factor. Timely started anti-Koch's treatment with adjuvant corticosteroid therapy has a direct bearing on patient outcome.

Abstract
As artemether/lumefantrine is now deployed as the first-line treatment for uncomplicated falciparum malaria in Bangladesh, information on its efficacy and adherence to its use is important. A randomised controlled non-inferiority trial comparing directly observed treatment (DOT) and non-directly observed treatment (NDOT) was conducted in 320 patients with uncomplicated falciparum malaria in Bandarban Hill Tract District, Bangladesh. Both regimens showed similar high levels of PCR-corrected 42-day parasitological and clinical cure rates (99.3% in the NDOT group and 100% in the DOT group; P=0.49). Survival analysis for the time to recurrence of infection showed no difference between treatment groups (log rank, P=0.98). Adherence, as assessed by counting remaining tablets and oral interviews, was 93% in the NDOT group and was confirmed by Day 7 lumefantrine concentrations. Adherence was independent of educational level. Patients with plasma lumefantrine concentrations < 280 ng/ml at Day 7 were at greater risk for re-infection (relative risk 5.62; P=0.027). The efficacy of artemether/lumefantrine for the treatment of uncomplicated falciparum malaria in Bangladesh is high and is similar for DOT and NDOT. Adherence to therapy is high.

Abstract
Five alternative techniques for diagnosis of malaria were evaluated in 124 clinically diagnosed cerebral malaria cases admitted in a tertiary hospital in Bangladesh. Clinical diagnosis of cerebral malaria was done by WHO criteria. The tests were conventional routine malaria microscopy; prolonged microscopy; dipstick antigen capture assay (Para Sight TM-F test); pigments in peripheral leucocytes and routine microscopy repeated at 12 hours interval. First four tests were done at 0 hours of hospital admission and repeat routine microscopy was added at 12 hours interval. Diagnostic capability of the test was 64%, 65%, 69%, 27% and 63% respectively. None of the tests except pigments in peripheral leucocytes was superior at initial evaluation. Only the dipstick test added 5% more diagnostic possibility compared with routine microscopy as standard. Stratification of diagnostic capability in different ways improved diagnosis 15% and 11% in smear negative cases by dipstick and prolonged microscopy respectively. It was increased by 50% (5/10 patients) with dipstick test in the smear negative patients with history of anti-malarials prior to hospital admission.

Abstract
BACKGROUND In Bangladesh, 4 outbreaks of Nipah virus infection were identified during the period 2001-2004. METHODS We characterized the clinical features of Nipah virus-infected individuals affected by these outbreaks. We classified patients as having confirmed cases of Nipah virus infection if they had antibodies reactive with Nipah virus antigen. Patients were considered to have probable cases of Nipah virus infection if they had symptoms consistent with Nipah virus infection during the same time and in the same community as patients with confirmed cases. RESULTS We identified 92 patients with Nipah virus infection, 67 (73%) of whom died. Although all age groups were affected, 2 outbreaks principally affected young persons (median age, 12 years); 62% of the affected persons were male. Fever, altered mental status, headache, cough, respiratory difficulty, vomiting, and convulsions were the most common signs and symptoms; clinical and radiographic features of acute respiratory distress syndrome of Nipah illness were identified during the fourth outbreak. Among those who died, death occurred a median of 6 days (range, 2-36 days) after the onset of illness. Patients who died were more likely than survivors to have a temperature >37.8 degrees C, altered mental status, difficulty breathing, and abnormal plantar reflexes. Among patients with Nipah virus infection who had well-defined exposure to another patient infected with Nipah virus, the median incubation period was 9 days (range, 6-11 days). CONCLUSIONS Nipah virus infection produced rapidly progressive severe illness affecting the central nervous and respiratory systems. Clinical characteristics of Nipah virus infection in Bangladesh, including a severe respiratory component, appear distinct from clinical characteristics reported during earlier outbreaks in other countries.

Abstract
BACKGROUND This study sought to describe and quantify microcirculatory changes in the mucosal surfaces of patients with severe malaria, by direct in vivo observation using orthogonal polarization spectral (OPS) imaging. METHODS The microcirculation in the rectal mucosa of adult patients with severe malaria was assessed by use of OPS imaging, at admission and then daily. Comparison groups comprised patients with uncomplicated falciparum malaria, patients with bacterial sepsis, and healthy individuals. RESULTS Erythrocyte velocities were measured directly in 43 adult patients with severe falciparum malaria, of whom 20 died. Microcirculatory blood flow was markedly disturbed, with heterogeneous obstruction that was proportional to severity of disease. Blocked capillaries were found in 29 patients (67%) and were associated with concurrent hyperdynamic blood flow (erythrocyte velocity, >750 mm/s) in adjacent vessels in 27 patients (93%). The proportion of blocked capillaries correlated with the base deficit in plasma and with the concentration of lactate. Abnormalities disappeared when the patients recovered. In healthy individuals and in patients with uncomplicated malaria or sepsis, no stagnant erythrocytes were detected, and, in patients with sepsis, hyperdynamic blood flow was prominent. CONCLUSION Patients with severe falciparum malaria show extensive microvascular obstruction that is proportional to the severity of the disease. This finding underscores the prominent role that microvascular obstruction plays in the pathophysiology of severe malaria and illustrates the fundamental difference between the microvascular pathophysiology of malaria and that of bacterial sepsis.

Abstract
Forty-four Plasmodium falciparum isolates from Bangladesh and 22 from western Thailand were successfully tested for their drug susceptibility. High degrees of resistance were observed against chloroquine with geometric mean IC50s of 114.25 and 120.5 nM, respectively, for Bangladesh and western Thailand. Most isolates from both sites were sensitive to quinine, and all were sensitive to artesunate. Many isolates were considered in vitro resistant to mefloquine, but the geometric mean IC50 for the Thai isolates (98.79 nM) was 1.6 times (P = 0.002) higher than that of isolates from Bangladesh (60.3 nM). The high prevalence of in vitro mefloquine resistance in Bangladesh suggests that close surveillance is necessary to delay widespread multidrug resistant problems in the area.

Abstract
During the mid 1990s, national guidelines were established in accordance with World Health Organization recommendations for the diagnosis of uncomplicated malaria in Bangladesh. Based on simple clinical and epidemiologic criteria these guidelines were designed to be applied outside of tertiary care centers where microscopy was not feasible. We evaluated the positive predictive value (PPV) of these criteria using microscopic slide examinations as the gold standard in 684 subjects diagnosed and treated for malaria, sampling from eight subdistrict centers. The PPV for malaria was 32% with 19% for falciparum and 14% for Plasmodium vivax. Medical officers assigned to the study also gave their own clinical impression of whether cases could have been malaria. With the additional criteria of a medical officers' diagnosis, the PPV increased negligibly to 37% with 23% and 14% for falciparum and vivax, respectively. Since the PPV of diagnosis is low and cannot be improved on clinical grounds alone, we recommend the incorporation of laboratory diagnosis. This is especially important as we detect resistance to the first-line therapy chloroquine and require more expensive, potentially more toxic, regimens.

Abstract
We performed an open, randomized chemotherapy trial comparing the recommended first-, second- and third-line drug regimens, as well as mefloquine, for uncomplicated falciparum malaria in Bangladesh in 1996-97. The regimens were chloroquine for 3 days (CQ, Group I), quinine sulphate for 3 days followed by single-dose sulfadoxine-pyrimethamine (Q3 + SP, Group II), quinine for 7 days (Q7, Group III), and mefloquine 20 mg/kg single dose (MEF, Group IV). Subjects were symptomatic patients, aged > or = 12 years, with parasite density 500-250,000/mm3 and no history of taking antimalarials during the previous week. Drug administration was supervised and subjects were followed clinically and with blood slides in the hospital for 8 days, then as outpatients on days 14, 21 and 28. A total of 413 subjects (149, 145, 49 and 70 in Groups I-IV, respectively) completed the study. Early treatment failures (persistent or worsening clinical manifestations by day 3 confirmed with parasitological examinations) occurred only in the chloroquine group. RII and RIII parasitological failures occurred in 56%, 12%, 8% and 14% in Group I-IV, respectively. There were significantly more clinical and parasitological failures with chloroquine than with Q3 + SP, which we now recommend as a better (but far from ideal) choice for first-line therapy. The alternative compounds show parasitogical evidence of Plasmodium falciparum resistance. Further studies are needed to determine the optimum treatment for malaria in Bangladesh.

Abstract
In vitro drug susceptibility profiles were assessed in 75 Plasmodium falciparum isolates from 4 sites in Myanmar. Except at Mawlamyine, the site closest to the Thai border, prevalence and degree of resistance to mefloquine were lower among the Myanmar isolates as compared with those from Thailand. Geometric mean concentration that inhibits 50% (IC50) and 90% (IC90) of Mawlamyine isolates were 51 nM (95% confidence interval [CI], 40-65) and 124 nM (95% CI, 104-149), respectively. At the nearest Thai site, Maesod, known for high-level multidrug resistance, the corresponding values for mefloquine IC50 and IC90 were 92 nM (95% CI, 71-121) and 172 nM (95% CI, 140-211). Mefloquine susceptibility of P. falciparum in Myanmar, except for Mawlamyine, was consistent with clinical-parasitological efficacy in semi-immune people. High sensitivity to artemisinin compounds was observed in this geographical region. The data suggest that highly mefloquine-resistant P. falciparum is concentrated in a part of the Thai-Myanmar border region.

Abstract
A randomized controlled trial on 51 patients receiving artemether and 54 patients receiving quinine was undertaken to compare the effectiveness of intramuscular artemether and parenteral quinine in the treatment of cerebral malaria in adults in Bangladesh. Case fatality, fever and parasite clearance times were not significantly different in the two treatment groups. Coma resolution time was significantly delayed in artemether recipients. Results of the study suggest that treatment with artemether is as effective as parenteral quinine in the treatment of cerebral malaria in adults.

Abstract
The study was done in a new settler's camp "Barachara" under Sadar thana of Cox's Bazar district. It has a total population of 784 of all age groups, registered in the middle of the study period. A prospective evaluation of all cases of fever were done over 12 months, to see the pattern of febrile illness among the population and to compare the therapeutic efficacy of two alternative drug regimens for uncomplicated falciparum malaria (UM). Blood for malarial parasite (MP) was done in all cases of fever and was treated in line with the new clinical case definitions and treatment guidelines for malaria in Bangladesh. Slide positive UM cases were subjected to a "14-day in-vivo test" for therapeutic efficacy testing of antimalarial agents. The two drug regimens were randomised by lottery--a) 3 days oral chloroquine plus single dose sulphadoxin/pyrimethamine (CQ + SP) and, b) 3 days oral quinine plus single dose sulphadoxin/pyrimethamine (Q3 + SP). Drug administration was supervised by the field assistant and was followed up on days 3, 7 and 14 for blood slide examinations and clinical assessment. Sensitive response was observed in 79% of the cases in the CQ + SP group and 84% in the Q3 + SP group. Early treatment failure (persistently febrile and parasitaemic on days 3 or 7) was observed in 16% in the CQ + SP group and 9% in the Q3 + SP group. Both the evaluated drug regimens had less than 20% failures and can be used as alternative first line agents and Q3 + SP regimens can also be used as the second line agents for treatment failure (to chloroquine and/or SP) UM cases in the study area.

Abstract
One hundred and four adult cases of cerebral malaria (73 male, 31 female) were studied between July 1995 to June 1996 in Chittagong Medical College Hospital. Diagnosis of cerebral malaria was based on unrousable coma or any neurological manifestation in a febrile patient with asexual Plasmodium falciparum in blood film. Intermittent fever (83%), vomiting (80%), headache (75%), convulsion (60%) and history of travel or residence in malaria endemic area were important features noted in patients with cerebral malaria. Most of the patients (69%) were admitted within 25 to 48 hours following unconsciousness. The factors are more common in cases with high mortality with diastolic blood pressure (DBP) below 60 mm of Hg, anaemia, persistence of Glasgow Coma Score below 5 on day 2, high parasite count at presentation, proteinuria and high level of serum urea. Out of 104 cases of cerebral malaria 66 patients (63.5%) recovered without sequelae, 34 patients (32.7%) died and 4 patients (3.8%) recovered with some residual sequelae. Establishment of intensive care unit in tertiary level hospitals is necessary to take appropriate measure for severe cerebral malaria cases for reduction of mortality.

Abstract
We identified the presence of a range of proteolytic enzyme types, normally associated with the process of general intracellular protein catabolism in mammalian tissues, in venom samples from several species of snake and from three subspecies of Russell's viper. Although levels of protease activity in venoms were in general substantially lower than corresponding levels in mammalian tissues, activity levels were comparable with several other classes of enzyme normally considered as significant venom components. Based on the protease types and relative levels of activity present in venom samples, we suggest that a possible function of these enzymes (in addition to their generally held function to increase target tissue permeability to other venom components) may be to interfere with the process of neurotransmission in target tissues, via degradation of neurotransmitter/neuromodulatory oligopeptides; this may be particularly the case for proteases such as leucyl aminopeptidase, the activity of which is greater in some venom types than in mammalian tissues. For the purposes of inter- and intra-species taxonomic classification of snakes, we would suggest that determination of a comprehensive venom protease profile may be of considerable value (particularly for subspecies differentiation) either in conjunction with or in place of more conventionally applied techniques such as analytical electrophoresis.

Abstract
The study was carried out in Medicine and Pediatrics Department of Rajshahi Medical College Hospital, and Natore Sadar Hospital, both are located in the northern territory of Bangladesh. Period of study ranged from admission of patients till discharge. On 8th June 2008, 83 patients of Singra Upazilla Natore were admitted in Rajshahi Medical College Hospital and Natore Sadar Hospital with the history of consumption of Puffer fish. A presumptive diagnosis of Puffer fish poisoning was made on the basis of classical clinical presentations followed by Puffer fish ingestion. Blood and urine samples from 38 patients were sent to Frankfurt, Germany for toxicological analysis. The cases were clinically reviewed periodically and routine investigations were done. Report of the toxicological study confirmed the diagnosis of tetrodotoxin poisoning. Important neurological symptoms observed were peri-oral paresthesia (71), tingling over entire body (50), dizziness (35), headache (20). Muscular paralysis of the limbs was noted in 13 patients, of which 7 patients developed respiratory involvement. All the patients who developed respiratory involvement died. Early diagnosis and supportive management could ensure a safe and favorable outcome. Management of respiratory failure by ventilator support can be life saving. doi: 10.3329/taj.v21i2.3790 TAJ 2008; 21(2): 121-125
