Abstract
Antimicrobial peptides represent an important component of the innate immune defenses of living organisms, including humans. They are broad-spectrum surface-acting agents secreted by the epithelial cells of the body in response to infection. Recently, L-isoleucine and its analogues have been found to induce antimicrobial peptides. The objectives of the study were to examine if addition of L-isoleucine to oral rehydration salts (ORS) solution would reduce stool output and/or duration of acute diarrhoea in children and induce antimicrobial peptides in intestine. This double-blind randomized controlled trial was conducted at the Dhaka Hospital of ICDDR,B. Fifty male children, aged 6-36 months, with acute diarrhoea and some dehydration, attending the hospital, were included in the study. Twenty-five children received L-isoleucine (2 g/L)-added ORS (study), and 25 received ORS without L-isoleucine (control). Stool weight, ORS intake, and duration of diarrhoea were the primary outcomes. There was a trend in reduction in mean +/- standard deviation (SD) daily stool output (g) of children in the L-isoleucine group from day 2 but it was significant on day 3 (388 +/- 261 vs. 653 +/- 446; the difference between mean [95% confidence interval (CI) (-)265 (-509, -20); p = 0.035]. Although the cumulative stool output from day 1 to day 3 reduced by 26% in the isoleucine group, it was not significant. Also, there was a trend in reduction in the mean +/- SD intake of ORS solution (mL) in the L-isoleucine group but it was significant only on day 1 (410 +/- 169 vs. 564 +/- 301), the difference between mean (95% CI) (-)154 (-288, -18); p = 0.04. The duration (hours) of diarrhoea was similar in both the groups. A gradual increase in stool concentrations of beta-defensin 2 and 3 was noted but they were not significantly different between the groups. L-isoleucine-supplemented ORS might be beneficial in reducing stool output and ORS intake in children with acute watery diarrhoea. A further study is warranted to substantiate the therapeutic effect of L-isoleucine.

Abstract
BACKGROUND As the signs of dehydration often overlap with those of pneumonia, it may be difficult for health workers in resource-poor settings to make a clinical diagnosis of pneumonia in children with dehydration. This issue has received very little attention. AIM To compare the clinical features of pneumonia in children with and without dehydration caused by diarrhoea. METHODS All children aged 2-59 months with diarrhoea and radiologically confirmed pneumonia admitted to the Special Care Ward (SCW) of Dhaka Hospital, ICDDR,B between September and December 2007 were enrolled for the study. Children with dehydration (67 cases) and those without (101 controls) were compared. RESULTS Cases presented less frequently with fast breathing (60% vs 88%, p<0.001) and lower chest-wall indrawing (67% vs 82%, p=0.035) than did controls. In logistic regression analysis, cases more often had severe malnutrition (OR 2.31, CI 1.06-5.02, p=0.035) and cyanosis (OR 19.05, CI 1.94-186.68, p=0.011) and were abnormally sleepy (OR 372, CI 1.71-8.08, p=0.001). CONCLUSIONS Fast breathing and lower chest-wall indrawing may be less reliable for the diagnosis of pneumonia in children with dehydration, especially when there is severe malnutrition.

Abstract
This prospective study evaluated the usefulness of the kala-azar latex agglutination test (KAtex) for the diagnosis and laboratory assessment of initial cure of visceral leishmaniasis (VL) (or kala-azar) patients following 30 days of sodium antimony gluconate treatment at Rajshahi Medical College Hospital (Bangladesh). KAtex detects a low molecular weight, heat-stable, carbohydrate antigen in the urine of VL patients. KAtex was performed using freshly voided urine samples obtained from 36 parasitologically confirmed cases of VL before and after treatment as well as from 40 healthy controls (20 each from kala-azar-endemic and non-endemic zones). KAtex was found to be positive in 27 (75%) of the 36 patients at diagnosis and was negative in all the controls. The diagnostic sensitivity and specificity of KAtex were 75% (95% CI 57-87%) and 100% (95% CI 89-100%), respectively. Following treatment, all 36 VL cases were negative for Leishman-Donovan bodies by splenic smear microscopy and 34 (94.4%) were negative by KAtex. This limited study suggests that KAtex is a satisfactorily sensitive, highly specific, rapid and completely non-invasive urine-based antigen detection test for the diagnosis of VL. Currently, this is the only non-invasive laboratory tool useful for the assessment of initial cure in VL patients.

Abstract
The study evaluated the usefulness of Leishmania-nested polymerase chain reaction (Ln-PCR) for diagnosis of kala-azar and assessed its role as a test of cure among kala-azar patients in Bangladesh. Peripheral blood buffy coat Ln-PCR was done in ninety-seven (97) clinically suspected patients of kala-azar, in forty (40) healthy controls from both endemic and non-endemic areas, and in forty-six (46) patients after completion of treatment with sodium stibogluconate (SSG). The Ln-PCR results were compared with Leishmania donovani parasite load graded by 1+ to 6+ in all smear-positive L. donovani cases. Out of 97 clinically suspected kala-azar patients, 94 were parasitologically confirmed. Ln-PCR was found positive in 91 of 94 parasitologically positive patients of kala-azar at diagnosis, indicating its diagnostic sensitivity as 97%. None of the controls was found positive for Ln-PCR, indicating its diagnostic specificity to be 100%. About 9% of kala-azar patients having been graded 1+ parasitic load had negative Ln-PCR results. After completion of treatment, Ln-PCR was positive in 4 patients (8.4%) out of 46 cases, indicating its role in demonstrating the absence of parasites 30 days after completion of treatment in 91.6% of the treated patients. This limited study suggests that Ln-PCR is a highly sensitive and specific test for the diagnosis of visceral leishmaniasis and can be used as a test of cure. Thus, efforts should be made to establish this useful method at least in the tertiary care hospitals and, if possible, at the district-level hospitals, especially in the endemic areas of Bangladesh.

Abstract
Dissociative (conversion) disorders are common among the patients attending in and out patients of Psychiatry Department of tertiary hospitals in Bangladesh. This study was done to see the subtypes of dissociative (conversion) disorder according to International Classification of Diseases, Tenth Revision (ICD-10). This is a descriptive, cross sectional study done on 100 consecutive patients from the Departments of Psychiatry, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka and Dhaka Medical College Hospital (DMCH). Study period was July 2005 to June 2006. Among the patients of dissociative (conversion) disorder, mixed dissociative (conversion) disorder was found highest 34%, followed by dissociative convulsion 33%, dissociative motor disorders 19%, dissociative anaesthesia and sensory loss 5%, dissociative amnesia 4%, dissociative fugue 3%. However, the researcher did not find any multiple personality disorder which is relatively common in North America. This finding reflected that there are differences in prevalence of sub types of dissociative disorders in Bangladesh and Western countries.

Abstract
BACKGROUND Diarrheal illnesses remain a leading cause of morbidity and mortality globally, with increasing recognition of long-term sequelae, including postinfectious irritable bowel syndrome and growth faltering, as well as cognitive deficits in children. Identification of specific etiologic agents is often lacking. In vitro and in vivo data suggest that enterotoxigenic Bacteroides fragilis (ETBF) may contribute to the burden of colonic inflammatory diarrheal disease. The study goal was to investigate the pathogenesis of ETBF diarrheal illnesses. METHODS We performed an observational study of children and adults with acute diarrheal illnesses in Dhaka, Bangladesh, from January 2004 through November 2005, to define the clinical presentation, intestinal inflammatory responses, and systemic and intestinal antibody responses to ETBF. Other enteric pathogens were also evaluated. RESULTS ETBF was identified to cause a clinical syndrome with marked abdominal pain and nonfebrile inflammatory diarrhea in both children (age, >1 year) and adults. Fecal leukocytes, lactoferrin, and proinflammatory cytokines (interleukin 8, tumor necrosis factor-alpha)-as well as B. fragilis toxin systemic antitoxin responses-increased rapidly in ETBF-infected patients. Evidence of intestinal inflammation often persisted for at least 3 weeks, despite antibiotic therapy. CONCLUSIONS ETBF infection is a newly recognized cause of inflammatory diarrhea in children and adults. Future studies are needed to evaluate the role of ETBF in persistent colonic inflammation and other morbid sequelae of acute diarrheal disease.

Abstract
A case of typhus fever is presented. On admission, the clinical diagnosis was typhoid fever. Forty-eight hours after admission, the presence of subconjunctival haemorrhage, malena, and jaundice raised the possibility of a different aetiology, the two most likely differentials being dengue and typhus. Finally, a co-infection of typhoid and typhus was discovered. This uncommon clinical scenario should be taken into account in the management of patients with high fever on admission being treated as a case of typhoid fever.

Abstract
Data on the aetiology of diarrhoea in neonates are scarce, especially from developing countries including Bangladesh. A retrospective review of the electronic database of the Microbiology Laboratory of the International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B), was carried out to examine enteropathogens associated with diarrhoea in neonates. Stool specimens of the neonates on admission to the Dhaka Hospital of ICDDR,B were collected and sent to the laboratory for direct plating onto taurocholate tellurite gelatin agar, Salmonella-Shigella agar and MacConkey's agar. Stool specimens of 2511 neonates of either sex were examined. Bacterial pathogens were recovered from the stools of 699 (27.8%) of these neonates--a single bacterial pathogen from 670 neonates and more than one pathogen from 29 neonates. Vibrio cholerae, Shigella, Salmonella, Aeromonas spp. and Plesiomonas shigelloides were isolated from 294, 108, 52, 222 and 19, respectively, of the neonates. The year-wise isolation of these pathogens varied between 4.9-23.4%, 2.7-5.4%, 0-4.7%, 0-19.4% and 0-1.6%, respectively, of the neonates. The results of the study indicate that infection by V. cholerae, Shigella spp., Salmonella spp., Aeromonas and P. shigelloides is common in neonatal diarrhoea in Bangladesh.

Abstract
BACKGROUND Partially hydrolyzed guar gum (PHGG) is a water-soluble fiber if added to oral rehydration solution (ORS) and undergoes fermentation in the colon liberating short chain fatty acids (SCFAs). SCFAs potentiate the effect of ORS, reducing the severity of diarrhea. AIM To examine the effect of PHGG-added ORS in reducing the stool output and duration of diarrhea in adult cholera. METHODS 195 male patients were studied in a randomized controlled trial: (a) 65 received ORS + 25 g PHGG; (b) 65 received ORS + 50 g PHGG, and (c) 65 received ORS alone (control). Major outcomes were stool weight and duration of diarrhea. RESULTS No significant differences were found in mean +/- SD stool weight (g/kg b.w.) during the first and second 24 h. In the subgroup analysis (excluding very high purging patients, stool weight in the first 24 h was >10 kg), the stool weight (g/kg b.w.) was significantly reduced in the first 24 h in both groups receiving PHGG (PHGG 25 g, 136 +/- 68 vs. PHGG 50 g, 144 +/- 49 vs. control, 176 +/- 43, p = 0.01). CONCLUSION PHGG-added ORS might have a beneficial effect in moderately purging adult cholera. However, further studies are warranted to confirm the preliminary findings.

Abstract
A 12-year-old boy was admitted in paediatric nephrology unit of Bangabandhu Sheikh Mujib Medical University (BSMMU) with massive proteinuria, hypertension, respiratory distress and anaemia and diagnosed as nephrotic syndrome. Percutaneous needle biopsy was consistent with diffuse endocapillary proliferative glomerulonephritis and initially managed conservatively with injection methyl prednisolone, cyclophosphamide, lisinopril etc. without any improvement. Living-related renal transplantation was done successfully from paternal uncle. Two episodes of acute rejection occurred, one immediately after transplantation and another after one month. These were managed with IV methyl prednisolone for 3 days. At present, he is on oral prednisolone, cyclosporine, azathioprine and antihypertensives with normal haemoglobin and stable serum creatinine level (pre-transplant level 12.5mg/dl to post-transplant level 1.5mg/dl). He has been maintaining his normal life including schooling for last few months. It is concluded that a patient with uncommon presentation of nephrotic syndrome should be confirmed by renal biopsy and renal transplantation may be considered if conservative measures fail.

Abstract
BACKGROUND Management of severe and very severe pneumonia in children relies on hospital-based treatment, but practical barriers often prevent children in areas with the highest rates from receiving hospital care. OBJECTIVE To develop and prospectively evaluate a day-care clinic approach, which provided antibiotics, feeding and supportive care during the day with continued care provided by parents at home, as an effective alternative to hospitalisation. METHODS Children aged 2-59 months with severe or very severe pneumonia without associated co-morbidities, denied admission to hospital because of lack of beds, were enrolled at Radda Clinic, Dhaka and received antibiotics, feeding and supportive care from 08:00 to 17:00 every day, while mothers were educated on continuation of care at home during the night. RESULTS From June 2003 to May 2005, 251 children were enrolled. Severe and very severe pneumonia was present in 189 (75%) and 62 (25%) children, respectively, and 143 (57%) were hypoxaemic with a mean (SD) oxygen saturation of 93 (4)%, which increased to 98 (3)% on oxygen therapy. The mean (SD) day-care period was 7 (2) days. Successful management was possible in 234 children (93% (95% CI 89% to 96%)), but 11 (4.4% (95% CI 2.5% to 7.7%)) had to be referred to hospital, and six (2.4% (95% CI 1.1% to 5.1%)) discontinued treatment. There were no deaths during the day-care study period; however, four children (1.6% (95% CI 0.6% to 4.0%)) died during the 3-month follow-up period, and 11 (4.4% (95% CI 2.5% to 7.7%)) required hospital admission. CONCLUSION Severe and very severe pneumonia in children without associated co-morbidities such as severe malnutrition can be successfully managed at day-care clinics.

Abstract
INTRODUCTION It is very important that patients are given sufficient time to consider the implications of surgical treatment. PATIENTS AND METHODS The authors audited the consenting practices for patients undergoing surgery in a busy ENT unit. RESULTS The first cycle demonstrated that 15% of patients were providing written consent for surgery on the same day as their operation. Subsequent to a simple change in departmental policy, this was reduced to 2%. The medicolegal implications of this audit are discussed with reference to current recommendations. CONCLUSIONS This simple policy change not only protects the hospital trust from potential litigation but also provides a smooth journey for the patients from diagnosis to making the decision to operate and finally to undergoing surgery.

Abstract
The present study aimed to observe the clinical features of hypoglycaemia, and identify predictors of hypoglycaemia in under-five diarrhoeal children requiring hospitalization for close observation and support. Such information could be useful to the clinicians and policy makers in developing appropriate management protocols both for identification of such children and optimizing their management. We performed a prospective study in 782 under-five children who presented with diarrhoeal illnesses. Blood glucose was determined when hypoglycaemia was suspected in 598 (62%), and 65 (11%) of them were hypoglycaemic (study group). From the other 533 non-hypoglycaemic children, 195 were randomly selected as comparison group. Bacteraemia was significantly (P = 0.026) often detected in 17 out of 260 (7%) children as opposed to 3 out of 184 (2%) children who did not have a rapid glucose test performed. Among hypoglycaemic children, 7 (11%) were bacteraemic and among non-hypoglycaemic children 10 (5%) had bacteraemia. In univariate analysis, history of shorter (<72 h) pre-admission duration of diarrhoea (75 vs. 58%, P = 0.01), documented convulsion (28 vs. 11%, P < 0.001), shorter (<72 h) hospitalization (52 vs. 33%, P = 0.01), higher case fatality rate (28 vs. 14%, P = 0.02) were associated with hypoglycaemia. In logistic regression, bacteraemic children (with clinical sepsis) were 4 times more likely to develop hypoglycaemia (OR = 4.2, 95% CI = 1.4-12.9, P = 0.012). Therefore, in a diarrhoeal disease health care service with limited resources, a rapid bedside glucose test may be considered as an inexpensive alternative in the management decisions of diagnosing bacteraemia and initiating empiric antibiotic treatment.

Abstract
On 8 May 2004, the World Health Organization (WHO) and the United Nations Children's Fund (UNICEF) recommended routine administration of zinc in the management of children, aged less than five years, with acute diarrhoea. In making the recommendation, WHO and UNICEF also suggested careful monitoring for adverse events associated with routine administration of zinc, particularly unusual or excess vomiting. The study assessed, in a phase IV trial, i.e. post-marketing surveillance of zinc, the occurrence of adverse events during the first hour after the administration of the first dose of zinc in children with acute or persistent diarrhoea. The study was conducted at the Dhaka Hospital of ICDDR,B and at an outpatient clinic operated by a local health NGO-Progoti Samaj Kallyan Protisthan (PSKP), Dhaka, Bangladesh. Eligible children, aged 3-59 months, were treated with 20 mg of zinc sulphate provided in a dispersible tablet formulation. The children were observed for 60 minutes following the initial treatment with zinc for adverse events, with particular attention given to vomiting or regurgitation. During the one-year observation period, 42,440 children (male 57% and female 43%) received zinc, and 20,246 (47.8%) of them were observed. Regurgitation and/or vomiting occurred in 4,392 (21.8%) of the children; 90.8% of these children had vomiting only once, 8.7% twice, and 0.5% more than twice. No children revisited the hospital for recurrent vomiting following their discharge. A significant proportion of infants and children may experience vomiting or regurgitation, usually once, following the administration of the first dose of zinc. This is a transient phenomenon that did not impact on continuation of treatment with zinc.

Abstract
Management of severely malnourished children with associated complications relies on hospital-based treatment. Implementation of a standardized protocol at the Dhaka Hospital, ICDDR,B reduced case fatality approximately 50%. We developed and prospectively evaluated a day-care clinic approach that provided antibiotics, micronutrients and feeding during the day with continued care by parents at home at night as an alternative to hospitalization. Severely malnourished children aged 6-23 months denied admission to hospital were enrolled at Radda Clinic, Dhaka and received protocolized management with antibiotics, micronutrients and milk-based diet from 8:00 am to 5:00 pm each day, while mothers were educated on continuation of care at home. They were transitioned to the day-care nutrition rehabilitation (NR) unit of Radda Clinic following resolution of acute illness, received NR diet (Khichuri, halwa and milk-based) daily until children attained 80% weight-for-length. From February 2001 to November 2003, 264 children were enrolled; 52% were boys and 78%, 21% and 1% had marasmus, marasmus-kwashiorkor and kwashiorkor, respectively. Only 13% had severe malnutrition alone while 35% had pneumonia, 35% had diarrhea and 17% had both pneumonia and diarrhea. The mean (SD) duration of acute and NR phases were 8 (4) and 14 (13) days, respectively. Children gained weight [mean (SD) g/kg day] more rapidly during acute 10 (7) than NR phase 6 (5). Successful management was possible in 82% (95% CI 77-86%) children, 12% discontinued treatment and 6% referred to hospitals. Only one child died during NR phase. Severely malnourished children can be successfully managed at existing day-care clinics using a protocolized approach.

Abstract
This prospective study was made to asses the results of total hip replacement done primarily at Dhaka Medical College Hospital by the surgical team from its orthopaedic department. Eight patients were selected randomly from April/2005 to December/2005. Six patients were male and two females. Age of the patients was ranging from 22 to 67 years with average of 37.4+/-5.12 (mean+/-SE) years. Majority of the patients (75%) were diagnosed as Aseptic necrosis of femoral head with secondary osteoarthritis. The femoral head was replaced by metallic component with C-stem and the acetabular cup made up of Ultra-High density Polyethylene. Both the components were cemented (methylmethacrylate) by hand-packing. The patients were followed-up for 7.75+/-6.1 months (mean+/-SE) ranging from 4 months to 1 year. The results were evaluated on the basis of Harris Hip Score(2). 75 % had good to excellent and 12.5% had fair results. One patient complicated with dislocation and ultimately had poor result. The quality of life in seven patients (87.5%) improved much for which they were grateful.

Abstract
The relationship between sinus disease and headache is complicated. We undertook a prospective study to examine the success of endoscopic sinus surgery for the alleviation of headache in a defined group of individuals. In particular we wished to discover whether the presence of asthma, nasal polyposis and purulent rhinosinusitis indicated that surgical intervention achieved any greater relief of symptoms compared to those without these conditions. Overall we found a significant improvement in headache symptoms after endoscopic sinus surgery, but subgroup analysis of patients with or without asthma, nasal polyposis and purulent rhinosinusitis showed no differences between the groups.

Abstract
We investigated cellular and humoral immune responses to oral biofilm bacteria, including Streptococcus mutans, Streptococcus anginosus, Streptococcus sobrinus, and Streptococcus sanguinis, in NOD/SCID mice immunized with human peripheral blood mononuclear cells (hu-PBMC-NOD/SCID mice) to explore the pathogenicity of each of those organisms in dental and oral inflammatory diseases. hu-PBMC-NOD/SCID mice were immunized by intraperitoneal injections with the whole cells of the streptococci once a week for 3 weeks. FACS analyses were used to determine the percentages of various hu-T cell types, as well as intracellular cytokine production of interleukin-4 and interferon-gamma. Serum IgG and IgM antibody levels in response to the streptococci were also determined by enzyme-linked immunosorbent assay. S. anginosus induced a significant amount of the proinflammatory cytokine interferon-gamma in CD4(+) and CD8(+) T cells in comparison with the other streptococci. However, there was no significant differences between the streptococci in interleukin-4 production by CD4(+) and CD8(+) T cells after inoculation. Further, S. mutans significantly induced human anti-S. mutans IgG, IgG(1), IgG(2), and IgM antibodies in comparison with the other organisms. In conclusion, S. anginosus up-regulated Th1 and Tc1 cells, and S. mutans led to increasing levels of their antibodies, which was associated with the induction of Th2 cells. These results may contribute to a better understanding of human lymphocyte interactions to biofilm bacteria, along with their impact on dental and mucosal inflammatory diseases, as well as endocarditis.

Abstract
During 1989-2002, we studied the antimicrobial resistance of 3928 blood culture isolates of Salmonella enterica serotype Typhi (S. Typhi) in Dhaka, Bangladesh. Overall 32% (1270) of the strains were multidrug-resistant (MDR, resistant to chloramphenicol, ampicillin and trimethoprim-sulphamethoxazole); first detected in 1990 (rate of 8%), increased in 1994 (44%), declined in 1996 (22%, P<0.01 compared to 1994) and re-emerged in 2001 (36%) and 2002 (42%, P<0.01 compared to 1996). An increased MIC of ciprofloxacin (0.25 microg/ml) indicating decreased susceptibility to ciprofloxacin was detected in 24 (18.2%) out of 132 randomly selected strains during 1990-2002; more frequently in MDR than susceptible strains (46.3% vs. 5.5%, P<0.001), and the proportion of them rose to 47% in 2002 from 8% in 2000 (P<0.01). Ciprofloxacin (5 microg) disk diffusion zone diameters of < or =24 mm as break-point had 98% sensitivity and 100% specificity when compared with a ciprofloxacin MIC of 0.25 microg/ml as break-point for decreased susceptibility; being a useful and easy screen test. All strains were susceptible to ceftriaxone. The emergence of MDR S. Typhi with decreased ciprofloxacin susceptibility will further complicate the therapy of typhoid fever because of the lack of optimum treatment guidelines.

Abstract
Crohn’s disease is a chronic idiopathic inflammatory disease of the bowel, and in most cases it involves the small bowel and colon. Extraintestinal manifestations occur frequently and multiple organ systems may be affected. In contrast, nasal manifestations are extremely rare and only a few cases have been reported to date. Saddle nose deformity in a patient with Crohn’s disease has not been reported in the English literature. We report a case of such a deformity and the current literature on nasal manifestations in Crohn’s is reviewed. The normal diagnostic and therapeutic features are also discussed.

Abstract
This study was carried-out to evaluate the diagnostic accuracy of fine needle aspiration cytology (FNAC) and the role of FNAC in the diagnosis of prostatic lesions. FNAC was performed on 64 patients presented with enlarged prostate. Cytological diagnosis by fine needle aspiration (FNA) of the prostate was compared with histological diagnosis in 60 patients. Of these, 42 cases were cytologically diagnosed as benign lesions, 18 cases as malignant. In remaining 4 cases, materials were inadequate for diagnosis in one case and biopsy materials were not available in 3 cases. On histological examination, 42 cases which were cytologically diagnosed as benign, 40 cases were found to be benign and 2 cases were malignant histologically leading to 2 false negative diagnoses. Of the 18 cases diagnosed cytologically as malignant (considering atypical hyperplasia and carcinoma as malignant), 15 cases were proved to be so by histological examination. So there were false positive diagnoses in 3 cases. No patient suffered from any complication following the aspiration biopsy. The sensitivity of this study for detection of prostatic carcinoma was 88 percent; specificity was 93 percent and diagnostic accuracy 91.7 percent. In this prospective study, FNAC of prostate was found to be associated with high diagnostic yields. These data support the value of transrectal FNAC as sensitive, easy to perform method for sampling of an enlarged prostate. The procedure may be used as an efficient primary screening tool in the diagnosis of prostatic lesions. Frequent use of this technique in our country should be encouraged.

Abstract
Neurotensin (NT) is a tridecapeptide that functions as a neurotransmitter and neuromodulator in the nervous system. To date, three different types of NT receptor (NTR), NTR1, NTR2 and NTR3, have been identified only in mammalian species. In the present study we isolated the cDNAs for an NTR1 and a novel NTR in the bullfrog brain, designated bfNTR1 and bfNTR4 respectively. bfNTR1 and bfNTR4 encode 422- and 399-amino acid residue proteins respectively. bfNTR1 has a 64% amino acid identity with mammalian NTR1, and 34-37% identity with mammalian NTR2. bfNTR4 exhibits 43% and 45-47% identity with mammalian NTR1 and NTR2 respectively. Both receptors are mainly expressed in the brain and pituitary. bfNTR1 triggers both CRE-luc, a protein kinase A (PKA)-specific reporter, and c-fos-luc, a PKC-specific reporter, activities, indicating that bfNTR1 can activate PKA- and PKC-linked signaling pathways. However, bfNTR4 appears to be preferentially coupled to the PKA-linked pathway as it induces a higher CRE-luc activity than c-fos-luc activity. bfNTRs exhibit different pharmacological properties as compared with mammalian NTRs. Mammalian NTR1 but not NTR2 responds to NT, whereas both bfNTR1 and bfNTR4 show a high sensitivity to NT. SR 48692 and SR 142948A, antagonists for mammalian NTR1 but agonists for mammalian NTR2, function as antagonists for both bfNTR1 and bfNTR4. In conclusion, this report provides the first molecular, pharmacological and functional characterization of two NTRs in a non-mammalian vertebrate. These data should help to elucidate the phylogenetic history of the G protein-coupled NTRs in the vertebrate lineage as well as the structural features that determine their pharmacological properties.

Abstract
OBJECTIVE To assess reproducibility and validity of resting metabolic rate (RMR) of Bangladeshi women as measured with the MedGem device and using the Deltatrac metabolic monitor as a reference; and (2) to evaluate the FAO/WHO/UNU basal metabolic rate (BMR)-prediction equations. DESIGN In each of two sessions, resting oxygen consumption was measured in triplicate by MedGem and in triplicate by Deltatrac device. SETTING Matlab area, the rural field research area of the Centre for Health and Population Research, Bangladesh (ICDDR,B). SUBJECTS A total of 37 nonpregnant, nonlactating women, aged 27.6 +/- 4.5 y, BMI 20.8 +/- 3.1 kg/m(2) participated. RESULTS The difference in oxygen consumption by MedGem and Deltatrac device was significantly level dependent. Within-subject within-session variations (expressed as CV) were 9.0 and 3.0% (P < 0.01) and within-subject between-session variations were 8.2 and 4.5% (P < 0.01) for MedGem and Deltatrac, respectively. Mean RMR measured by Deltatrac (5.17 +/- 0.51 MJ/day) was not significantly different from the BMR predicted by the FAO/WHO/UNU equations (5.16 +/- 0.42 MJ/day) in the second session and only 0.19 MJ/day higher than predicted in the first session (P < 0.05). CONCLUSION Reproducibility and validity of the MedGem device was poor compared to the Deltatrac reference method. The FAO/WHO/UNU BMR-prediction equations give a good estimation of the BMR of rural, nonpregnant, nonlactating Bangladeshi women of 18-35 y.
