Abstract
Kala-azar is one of the major public health problem in Bangladesh. But the diagnosis of the problem often is difficult, unusual and time consuming, a simple, noninvasive, easy to perform, reliable and rapid diagnostic test has been a long-felt need of the clinicians. Therefore, the present study was conducted to see the sensitivity and specificity of Latex Agglutination test (KAtex) to detect leishmanial antigen from urine of kala-azar cases. The study was carried out in the department of Paediatrics, Mymensingh Medical College and Hospital, Bangladesh during July to December, 2008. A total of 100 urine samples were collected of which 50 were confirmed kala-azar cases and 50 were age and sex matched controls. Out of 50 kala-azar cases 47 showed positive result of KAtex. The test was also positive in 01 out of 30 healthy controls. None of the febrile controls was positive by KAtex. The sensitivity, specificity, positive predictive value and negative predictive value of the test using presence of LD bodies in splenic and/or bone marrow aspirate as gold standard were 94%, 98%, 97.91% and 94.23% respectively. KAtex is simple, noninvasive, easy to perform, rapid and reliable test for diagnosing kala-azar in endemic area and useful for small, less equipped laboratories as well as for the laboratories with better facilities.

Abstract
This case control study was done to study the seropositivity of helicobacter pylori among the fish handlers and to find out rapid urease test (RUT) & haematoxillin and eosin staining report correlation of seropositive cases. It was performed among fish handlers in the period of July 2005 to June 2006. Blood samples were collected from fish handlers (Group I) and some non-fish handler control subjects (Group II) to perform Anti-H. Pylori IgG test by ELISA method. Samples were collected from both the sea water area (Paikgacha, Khulna) and fresh water area (Derai, Sunamgonj and Dhaka). Seropositive cases having complaints and treatment history of peptic ulcer diseases were motivated for endoscopic examination to collect biopsy from upper GIT and rapid urease test (RUT) hematoxillin & eosin (H & E) staining were performed. A total of 235 respondents were included in this study, among them 163 were fish handlers (80 sea water and 83 fresh water) and 72 were non fish handler control (25 sea water, 22 fresh water from Sunamgonj, 25 fresh water from Dhaka city). Serum anti- H. pylori test was positive in 126(77.30%) cases in fish handler group (a) and 27(37.5%) cases in the control group (b). Seropositive cases were observed more among the higher age group (>40 years) than in lower age group (<40 years) which was 86% and 67% respectively. Endoscopic examination was done among the seropositive cases having positive PUD features. Total seropositive cases were 153 and among them 81 have positive PUD features, among them 48 cases were selected for endoscopic examination. Among the fish handlers out of 34 cases, 31(91.17%) were RUT positive and out of 14 non-fish handlers 6(42.85%) were RUT positive. Among the fish handlers, 28(82.35%) of the 34-biopsy specimens were H & E positive and among the non-fish handlers, out of 14 samples, 5(35.71%) were H & E positive. Fish handlers have more association of H. Pylori infection than non fish handlers and higher age group persons are more prone to H. Pylori infection. A significant number of seropositive persons have association with positive RUT and H & E staining report.

Abstract
This retrospective study was conducted to determine the morbidity and mortality pattern of neonates admitted in to Mymensingh Medical College Hospital (MMCH). A total of 4826 neonates were admitted and reviewed during the period January 2003 to December 2003 in MMCH. Neonatal admission comprises 31.6% of total paediatric admission. Majority of the patients were 1 to 3 days of age and male. The top five causes for neonatal admission in MMCH were perinatal asphyxia (38.7%), low birth weight (25.7%), septicemia (19.2%), neonatal jaundice (5.9%), meconium aspiration syndrome (2.9%). The death rate of neonatal admission was 20.6%. The mortality was found among the neonates admitted with low birth weight (28.1%), perinatal asphyxia (22.8%), septicemia (18.9%). The average duration of hospital stay was higher among the septicemia patients than neonates suffering from other diseases. The finding of this study could be used by professionals, managers and policy makers to design neonatal health programmes to achieve millennium development goal (MDG) by the year 2015.

Abstract
This prospective study was undertaken in Dhaka Shishu Hospital from 15th March 2005 to 15th October 2006 to evaluate the role of simple hematological test for early diagnosis of neonatal sepsis. Eighty suspected cases of septicaemia admitted in neonatal ward of Dhaka Shishu Hospital were included in this study. Patients those who had history of perinatal asphyxia, infant of diabetic mother, congenital cyanotic heart disease etc. were excluded from the study. Thirty neonates without sign symptoms of septicaemia admitted for other causes like jaundice, feeding problems etc. were taken as a control group. After taking informed consent data were collected in structured questionnaire. Following laboratory investigations like total WBC count, differential count, absolute neutrophil count, band cell count, platelet count, CRP, blood culture were done. Micro-ESR was done as bed side test. Immature and total neutrophil ratio (I/T ratio) detected from total neutrophil and band form count. Patients with positive blood culture were categorized as definite sepsis. Patients with negative blood culture but abnormal hematological report suggestive of sepsis were categorized as probable sepsis. Those who had no signs of sepsis were categorized as control group. Absolute neutrophil count (ANC) had low sensitivity (13%) but Micro-ESR, CRP, I/T ratio, platelet count had moderately high sensitivity and specificity. These simple hematological screen are useful marker for early diagnosis of neonatal sepsis.

Abstract
The objective of this cross sectional prospective study was to determine rotavirus etiology and prevalence of the different rotavirus genotypes causing acute gastroenteritis in infants and children (</=5years) in Mymensingh Medical College Hospital, Bangladesh. The study was conducted during the period from January 2005 to June 2006. A total of 962 stool specimens from diarrheic children were analyzed by Polyacrylamide Gel Electrophoresis (PAGE). Rotavirus detection rate was 31.3% (301/962). Among the 71 representative rotavirus specimens examined genetically by RT-PCR, the most frequent G genotypes were G2 (57.7%), followed by G1 (21.1%), and G9 (15.5%). The G12 was detected from two specimens (2.8%) and was the first report in the study area. The predominant P genotypes were P[4] (54.9%), followed by P[6] (19.7%), and P[8] (15.5%). Among the single infection, the predominant G/P combinations were G2P[4] (52.1%), followed by G1P[8] (10%), and G1P[6] (8.5%). Nucleotide Sequence identity of VP7 gene of G2 rotaviruses were higher than 99.0% with each other and these G2 viruses showed genetically lower identity to G2 rotaviruses reported elsewhere in the world, except for some strains reported in African countries. All the G2 strains sequenced in this study were grouped into single cluster in phylogenetic tree for G2 strains. As rotavirus vaccine is implemented in immunization program worldwide, the hospital based surveillance study will provide valuable information to assess the future impact of vaccination.

Abstract
Serum samples from 465 subjects aged between 1 and 25 years were tested for antibody against hepatitis A virus (HAV) [anti-HAV IgG and IgM] to determine the seroprevalence of HAV antibody and do a cost-benefit analysis for decision making about vaccination against HAV among the general population of Bangladesh. A high prevalence of anti-HAV (74.8%) was observed in the study population; the whole study population was found positive for anti-HAV by the age of 25 years. On performing the cost-benefit analysis, it was found that the cost for vaccination with screening for anti-HAV was almost three times cheaper than vaccination without screening. Thus, in the present socioeconomic condition of Bangladesh, a policy based on screening for HAV antibody before vaccination is recommended.

Abstract
Zinc is being recognized increasingly as an important element in human growth, development and immunological function. It is probably the most intensely studied microelement in newborn nutrition. Zinc deficiency is common in young infants in the developing world and is associated with reduced immunocompetence and increased rates of serious disease. Preterm neonates are especially vulnerable because of preterm delivery and low birth weight. The preterm baby has very limited stored energy and needs an adequate supply of nutrient. Preterm infant have high zinc dietary requirements as 60% fetal zinc is acquired during third trimester of pregnancy. Low concentration of zinc was found in pre-term low birth weight babies in different studies. Studies showed that before supplementation serum zinc level in preterm low birth weight babies were 62+/-12.4 microgm/dl, 65 microgm/dl, 54+/-14.4 microgm/dl and after supplementation serum zinc level were 105.8+/-16.6 microgm/dl, 86.4+/-24.7 microgm/dl respectively. At the same time mean weight & length of supplementation and without supplementation group were 6084 gm vs. 5280 gm, 2779+/-638.7 gm vs. 2474.6+/-441.8 gm and length 23.7 cm vs. 21.4 cm, 46.49+/-2.6 cm vs. 44.1+/-2.8 cm respectively. So supplementation of zinc in preterm babies causes improved growth and development. Various reports showed beneficial effect of long supplement in early growth of pre-term babies. However long term follow up studies are needed to evaluate the beneficial effect of zinc supplementation on growth of preterm babies.

Abstract
In Bangladesh, the total population at risk for kala-azar exceeds 20 million (18%) living in 88 Thana (19%) of 27 districts (42%). A confirmatory diagnosis of visceral leishmaniasis (kala-azar) is done by demonstration of the parasite (LD body) in organ aspirates or tissue biopsy sample, an invasive procedure with relatively low sensitivity. To assess the diagnostic usefulness of ICT for antibody against the leishmanial antigen rK39 & its feasibility for use under field conditions (rural areas). An experimental study conducted during January, 2003 to July, 2003 in pediatrics department of MMCH including 60 confirmedly diagnosed KA cases & 60 controls having diseases other than KA. One drop of peripheral blood is applied to the nitrocellulose strip & 3 drops of test buffer is added to the dried blood. Observing 2 visible bands indicates presence of IgG anti-K39. The rK39 strip test was positive in 57 out of 60 confirmed KA case diagnosed by LD body demonstration in splenic or bone marrow aspirate. The estimated sensitivity was 95%. One control diagnosed as other than KA had positive strip test but negative aspirate smear. The estimated specificity of the strip test was 98.3%. The predictive value of a positive result is 98.3% & that of a negative result is 93.5%. rK39 strip test is highly sensitive & specific in our situation & it can be used as a simple & the best method for diagnosis of KA in rural areas.

Abstract
A female 38 years old, housewife, presented to the Department of Dermatology and Venereology, Mymensingh Medical College Hospital (MMCH) on 08.04.07 with the complaints of i) pain and reduced movement of hand, knee, shoulder and neck joints for 1 year and 9 months ii) tightness of skin over face, neck, limbs and trunk for 1 year and 6 months iii) patchy depigmentation over same areas for 1 year and 3 months iv) deformity of hands with flexion contractures for 6 months and v) dysphagia to solid food for 3 months. She had no complaints of Raynaud's phenomenon. On general examination, she was ill looking, anemic and nutritionally poor. Examination of integumentary system showed smooth, shiny, thick, hard and hidebound skin with pigmentary alteration of 'salt and pepper' appearance over fingers, hands, limbs, face, neck and trunk. Hands appear claw like but more on the right side than the left and there were no other obvious changes suggestive of digital ischaemia (atrophy, ulceration, scarring, gangrene etc). Face has got suggestive features of scleroderma. Examination of the respiratory system showed restriction of chest movement and reduced expansibility of chest wall. No other abnormality was found on examination of other systems. Laboratory investigations showed histopathology typical of scleroderma. X-ray of hands and feet showed suggestive changes, lung function test-showed restrictive lung disease. Barium swallow x-ray of esophagus in supine position showed mild dilation of lower oesophagus. But serology was non-reactive (negative ANA, Negative RA test, Negative VDRL). So, she was diagnosed as a case of progressive systemic sclerosis (PSS) with some atypicality.

Abstract
Low birth weight (LBW) is a major child health problem in Bangladesh and continuing to great threat to child health and child survival in Bangladesh. LBW is a silent emergency but crisis is real and its persistence has profound and frightening impact on neonatal mortality. This observational study was conducted in Dhaka Shishu Hospital, Dhaka, Bangladesh during July 2004 to June 2005. Serum zinc levels were estimated between two groups: group-I preterm AGA (n=50), group II preterm SGA (n=50) babies. Blood samples were collected from the study population in neonatal unit and serum zinc levels were measured by flame atomic absorption spectrophotometry in Atomic Energy Center, Dhaka, Bangladesh. Observed data were made comparison among groups by Students 't' test. It was observed serum zinc level (60.2+/-15.2) in group I and (62.1+/-12.4) in group II. Serum zinc level was in lower limit of normal range in both groups with more lower level in preterm AGA babies but their difference was not statistically significant (p>0.05). So zinc supplementation may enhance the growth of preterm LBW babies in their early months of lives.

Abstract
The present research has been designed to understand the effect of selenium and vitamin E on the lymphocyte and changes in the frequency of Ig-containing plasma cells in the lymphatic organ and ileum (representative organ for mucosa-associated lymphatic tissues) of different postnatal stages of Kasilla broiler chickens. A routine haematoxylin and eosin (H and E) stain were used to study the histology of the lymphocytic changes, and indirect immunoperoxidase staining method was performed for the study of the distributional and dynamical changes of the Ig-containing plasma cells within the lymphatic tissues and in the ileum of control broilers and in the broilers supplemented with different concentration of selenium and vitamin E in the diet. Histologically, the population of lymphocytes decreased in the lobules of the thymus, medulla of bursal follicles, splenic masses, lymphatic nodules of the cecal tonsil, and villi of the ilium in 0.1 mg and 0.5 mg selenium supplemented broilers in comparison with the control. The population of these cells was found to increase in 150 mg and 300 mg vitamin E supplemented chickens in the present study. In the spleen IgG- and the IgM-containing plasma cells were more than IgA-containing plasma cells. In contrast, in the cecal tonsil and ileum IgA-containing plasma cells were more than IgG- and IgM-containing plasma cells. The frequency of these immunopositive cells were decreased in 0.1 mg and 0.5 mg selenium supplementated chickens, and increased their frequency in the chickens supplemented with 150 mg and 300 mg vitamin E. In the spleen the frequency of IgM-containing plasma cells and both in the cecal tonsil and ileum, the IgG-containing plasma cells were more decreased by selenium supplementation which restored in their population by vitamin E supplementation.

Abstract
Chronic ulcerative stomatitis (CUS) is a recently described mucocutaneous disease characterized by involvement of mucosal surfaces and skin. The disease usually presents in the form of painful oral ulcers and has been seen predominantly among older women. Clinically, CUS patients may exhibit erosive or ulcerative lesions of oral mucosa resembling erosive lichen planus and/or other vesiculobullous lesions. Routine histology may exhibit features of lichenoid mucositis and is often nondiagnostic. Direct immunofluorescence studies of mucosal or skin biopsies usually reveal a unique pattern of IgG bound to nuclei of keratinocytes of the basal and parabasal cell layers. Chronic ulcerative stomatitis exhibits a unique resistance to standard treatments available, including topical and systemic corticosteroids and immunomodulatory medications. However, long-lasting favorable clinical responses may be achieved with hydroxychloroquine pharmacotherapy. We present the clinicoimmunopathologic findings of four cases of CUS and discuss the varied clinical, microscopic spectrum, and treatment for this chronic, debilitating, and often recalcitrant condition. A systematic review of the literature, including 35 previously reported cases, is presented.

Abstract
Eukaryotic initiation factor 6 (eIF6), an essential protein important in ribosome biosynthesis and assembly, was identified as an interacting partner of the beta-catenin C terminus in the yeast two-hybrid assay. Independent studies identified Drosophila eIF6 (DeIF6) in a genetic screen designed to detect new genes involved in the regulation of the Wnt/Wg (wingless) pathway. Ectopic expression of DeIF6 in wing discs results in a Wg phenotype. Expression of eIF6 in adenomatous polyposis coli (APC)-mutant colon cancer cells, which express high levels of active beta-catenin, showed that eIF6 selectively inhibits the Wnt pathway at the level of beta-catenin protein independently of proteasomal degradation. Incorporation of radiolabeled amino acids into beta-catenin was selectively decreased in cells that overexpressed eIF6. A similar inverse relationship of the two proteins was observed in the APC(min/+) mouse intestine, in which beta-catenin levels are very high. Taken together these data reveal a link between eIF6 and Wnt signaling, perhaps at the level of ribosome recycling on beta-catenin mRNA.

Abstract
This case control study was carried out in the Paediatric wards of Mymensingh Medical College Hospital for a period of one year from April 2002 to March 2003 to determine the sensitivity, specificity and predictive values of Aldehyde test in the diagnosis of Kala-azar. A total of seventy five febrile cases of Kala-azar from Paediatric wards were enrolled in the study and Seventy five controls having splenomegaly with or without fever were also included from the same source. Aldehyde test was done in both cases and controls. Diagnosis of Kala-azar was confirmed by demonstration of Leish-man-Don-o-van body (LD) in bone marrow or splenic aspirates. Out of 75 parasitologically proven cases of Kala-azar, AT was positive in 56 cases. The sensitivity irrespective of duration of illness was 74.6%. We found sensitivity of AT increases with the duration of illness where AT was sensitive in 34.7% cases having fever for less than 3 months, 90.90% with fever for 3 months to less than 6 months and 100% with fever for 6 months or more in duration. Specificity of AT was calculated as 96% with positive and negative predictive values of 94.9% and 79.1% respectively. So AT is a very sensitive and specific test with high positive and negative predictive values. Considering the cost, availability, simplicity, sensitivity, and specificity we would recommend the Aldehyde test as an important diagnostic tool for field diagnosis of Kala-azar especially after three months of febrile illness.

Abstract
An intervention study was carried out in Paediatric wards for a period of one year from January 2003 to December 2003 to determine the efficacy and safety of azithromycin in the treatment of uncomplicated childhood typhoid fever. A total of 50 cases were enrolled in the study. The inclusion criteria of the cases were: documented fever for more than 7 days plus two or more of the following clinical features: toxic appearance, abdominal tenderness, hepatomegaly, splenomegaly, diarrhoea, constipation and coated tongue plus positive Widal test and/or blood culture positivity. Patients who had complication like gastrointestinal tract (GIT) haemorrhage; intestinal perforation and/or shock were excluded from the study. Data were collected in a structured questionnaire. Azithromycin was given at a dose of 10mg/kg /day for a period of 07 days. The time to defervescence was 3.82+/-1.49 days. The minimum defervescence time was 02 days and maximum was 07 days. Clinical cure rate was 94%. No serious adverse effect was noted related to azithromycin therapy except nausea, vomiting, and jaundice. Prior treatment with antibiotics did not affect defervescence time (P>0.05). Pre-treatment febrile period has got positive and linear correlation with clinical response (r = +0.593). It was found that once daily administration of oral azithromycin for seven days in the treatment of uncomplicated typhoid fever was effective and reasonably safe.

[PMID: 17445851 DOI: 10.1016/j.tice.2007.02.005] [Citation(s) in RCA: 16] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2006] [Revised: 01/24/2007] [Accepted: 02/12/2007] [Indexed: 11/28/2022]
Abstract
The distribution and frequency of immunoglobulin (Ig)-containing plasma cells, their variations due to sex, and the mode of secretion of Ig cells into the duct system of the Harderian gland was investigated in broiler and native chickens of both sexes in Bangladesh. The Harderian gland is covered by a capsule, and the connective tissue septa divide the gland into numerous unequal-sized numerous lobes and lobules. The Ig-containing plasma cells were located in the interstitial space, interacinar space, apical part of the lobule, and lumina of the lobules of the Harderian gland in both broiler and native chickens. The population of these Ig-containing plasma cells varied in between broiler and native chickens, and also between male and female broiler and native chickens. In the broiler, the number of IgM-containing plasma cells was higher; in contrast, in the native chickens, the population of IgA-containing plasma cells was larger. In the broiler, there were more IgA- and IgG-containing plasma cells in the male; in contrast, there were more IgM-containing plasma cells in female. In native chickens the frequency of IgA-containing plasma cells was greater in the female than male. When the data for broiler and native birds were compared, it was found that there were significantly more IgA- and IgG-containing plasma cells in the native male and female chickens than in the broiler males and females. The secretory Igs were located in the lumina of acini and the duct system of the Harderian gland. In the present study Ig-containing plasma cells were observed to be released in the lumina of the lobules of Harderian gland by the breakdown of acinar tissues in broilers, and by holocrine mode of secretion in the native chicken. These results suggested that the Harderian gland, even though it is not a lymphoid organ as a whole, but acts as an immunopotent organ in chickens, and that the gland in native chicken contains more Ig-containing plasma cells due to their scavenging.

Abstract
Intrauterine growth and birth weight are probably the most important factors that affect in survival and future quality of life. Intrauterine growth retardation causes program changes in body systems specially lipid metabolism that creates various problems of which coronary heart disease is important. Higher serum triglyceride (TG) level in IUGR babies relates to increase incidence of coronary heart disease. This cross sectional study was conducted in Bhangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh during July 2004 to June 2005. Serum TG levels were estimated among three groups: IUGR (n=30), preterm appropriate for gestational age (AGA) (n=30) and term normal (n=30) new born babies. Blood samples were collected from the study population in the neonatal unit and serum TG level were measured with all accuracy in a computerized automated biochemical analyzer in Biochemistry department of BSMMU. Statistical analysis were done by using student's 't' test. It was observed that serum TG level (54.4 +/- 11.2 mg/dl) in IUGR babies were significantly higher than that of term normal babies (38.7 +/- 5.8 mg/dl), p value < 0.05. This implicate future coronary heart disease in these babies as shown by others in long term prospective studies.

Abstract
A total of 345 stool specimens of hospitalized children below 5 years of age with acute gastroenteritis were tested for the presence of rotavirus by Polyacrylamide gel electrophoresis (PAGE), a monoclonal antibody based enzyme immunoassay (EIA) and a latex agglutination test (LAT). Detection rate for PAGE and EIA were 24.9% (345/86) and 20.9% (345/70) respectively. Using PAGE as the standard, the sensitivity and specificity of EIA were 75.6% and 98.1% respectively. The sensitivity of LAT was 70.9% with 100% specificity (LAT was done in only PAGE positive specimens). LAT appeared as the simplest and economic for both bed side and field use.

Abstract
The morphometry of the intercommissural distances and their relation with other structures of the aortic valve of bovine heart was carried out. A total of 32 apparently healthy bovine hearts of indigenous cattle of both sexes (50% male and 50% female), 2-4 years of age, weighing 500 to 800 gms were used in this study. The external intercommissural distances were higher in all cusps of the valve compared to the internal intercommissural distances. The internal intercommissural distance was larger in the RC sinus in case of male animals followed by that of the LC and NC sinus. The mean external intercommissural distances were 34.67+/-3.40, 34.40+/-3.64 and 34.97+/-4.37 mm and the internal intercommissural distances were 21.60+/-4.21, 21.20+/-4.70 and 20.67+/-4.06 mm for LC, RC and NC respectively. Analyzing the internal intercommissural distance, value in the LC sinus was higher followed by the RC and the NC but this variation was non-significant. In regard to the position of the coronary ostia, there were two coronary ostia, the right coronary ostium present in the RC sinus and the left coronary ostium in the LC sinus respectively and the right coronary ostium was supracommissural in position in bovine heart. Data about the morphometrical analysis of intercommissural distances and the position of the coronary ostia of the aortic valve facilitate the knowledge of manufacturing bovine tissue valve as well as those might be involved in valve replacement in human.
