Abstract
Ramadan fasting is one of the five pillars of Islam and is obligatory for all healthy adult and adolescent Muslims. A significant number of patients with diabetes observe fasting during Ramadan. The objectives of this Ramadan Perspective Epidemiology and Education in Diabetes (RAPEED) study were to find out the current knowledge, attitude, and practices about Ramadan fasting among people with diabetes in Bangladesh. This retrospective cross-sectional study recruited 648 subjects with diabetes mellitus attending the Endocrinology outpatient department of a tertiary level hospital of Bangladesh within two months of the end of Ramadan in 2016. Socio-demographic data, data related to diabetes treatment, complications and co-morbidities; changes in lifestyle and diabetes treatment during Ramadan and frequency of hypoglycemia were collected from all. The mean age of the study population was 50.32±12.1 years and the majority (98.6%) had type 2 diabetes and 63.9% were overweight or obese. The majority (89.35%) of the patients fasted in Ramadan and among them, more than half of the fasters received physicians' advice for Ramadan fasting (60.6%) and changed diabetes medication (69.90%) during Ramadan. Although the amount of total food consumption was unchanged in more than one half (60.6%) of the fasters, majority of them reduced sugar-sweet intake (75.5%), increased fluid drinking (75.8%) and decreased physical activity (75.8%) during the month. A large portion (37.48%) of them did not check blood glucose and more than half (54.06%) of fasters failed to visit their physicians during Ramadan. Among them 14.85% experienced mild to moderate episodes of hypoglycemia and none had severe hypoglycemia and the most (61.6%) episodes of hypoglycemia occurred in the late evening. Hypoglycemic episodes were more frequent among insulin users, patients who had received fasting advice from physicians and in those who had adjusted diabetes drugs before Ramadan fasting. Safe Ramadan fasting is a great challenge not only for the patients but also the consulting physicians. Current study reflects the necessity of both physicians' expertise and patients' awareness for safe fasting.

Abstract
The poultry industry has emerged as one of the largest and fastest growing public sectors in the developed and developing countries. Unfortunately, this industry is under a major threat from diseases that are viral (Newcastle disease, infectious bursal disease, influenza, hydropericardium syndrome), bacterial (colibacillosis, pasteurellosis, salmonellosis, mycoplasmosis), parasitic (coccidiosis, histoplasmosis) or nutritional (dyschondroplasia, osteoporosis). Among these diseases, hydropericardium syndrome (HPS) is one of the important emerging diseases occurring in the specific areas of the world where broilers (chickens) are reared under intensive conditions. HPS was first observed in 1987 at Angara Goth, an area near Karachi, Pakistan, where broilers are raised. Since then, HPS has been reported in many countries of the world. From these reported cases, an adenovirus that was either isolated from or visualized electron microscopically in the liver of affected broilers has been implicated in the syndrome. The syndrome has been reproduced by inoculation of isolated fowl adenovirus (FAdV) strains, and hence, the syndrome is also called infectious hydropericardium syndrome. To our knowledge, HPS has not been observed in humans, so it is not considered a zoonotic disease, but it is of economic importance and causes huge losses to the poultry industry. Efforts have been made to develop conventional vaccines against this disease, which were formulated from infected liver homogenate. Formalin-inactivated liver organ vaccines have failed to protect the poultry industry. Hence, there is a dire need to develop a suitable vaccine to combat this disease. Currently, recombinant vaccine candidates are being developed by using molecular biology and biotechnological approaches for the prevention and control of infectious diseases, including HPS. Therefore, it is suggested that the immunogenicity of these recombinant proteins should be evaluated for their use as subunit vaccines.

Abstract
Ophthalmologists are still facing difficulties in managing bacterial eye infections. The study was designed for the isolation and identification of bacteria from infected eyes and observation of the sensitivity and resistant pattern. This cross sectional study was performed among 160 patients of suspected bacterial eye infection at Dr. K. Zaman BNSB Eye Hospital, Mymensingh and Department of Microbiology and Hygiene, Bangladesh Agricultural University, Mymensingh from March, 2010 to June, 2014. After collection of the samples from suspected infected eyes, it was nourished into nutrient broth in shaking incubator for three hours and then cultured into nutrient agar media followed by Mannitol salt agar, MacConkey's agar and blood agar. Bacteria were categorized by colony characteristics and Gram staining. Antibiogram was performed by disc diffusion method on Mueller Hinton agar media. McFarland Equivalence Turbidity Standard was maintained. The efficacy of the drug was evaluated by measuring the diameter of the zone of inhibition surrounding the disc. Ten percent Staphylococcus species isolates was resistant to Gatifloxacin, Gentamicin, Tobramycin and Cloxacillin, 26.0% to Ciprofloxacin, 40.0% to Azythromycin and Moxifloxacin, 58.0% to Cefixime and 64.0% to Cephalexin. Methicillin resistant Staphylococcus aureus was 62.8%. About 24.0% Streptococcus species isolates was resistant to Gatifloxacin, 33.3% to Azythromycin, Ciprofloxacin, Gentamycin, Moxifloxacin and Tobramycin, 52.4% to Cefixime and 71.4% to Cephalexin. About 9.0% of Pseudomonas species was resistant to Gatifloxacin and Tobramycin, 14.7% to Ciprofloxacin, 26.5% to Cefixime, 29.4% to Gentamicin and Moxifloxacin, 44.1% to Azythromycin and 82.3% to Cephalexin and Cloxacillin. Rational use of antibiotics and proper attentions of concerned authorities are necessary to overcome the emergent ocular situation leaded by antibiotic resistant.

Abstract
BACKGROUND AND PURPOSE Although it is a potentially powerful presurgical tool, fMRI can be fraught with artifacts, leading to interpretive errors, many of which are not fully accounted for in routinely applied correction methods. The purpose of this investigation was to evaluate the effects of data denoising by independent component analysis in patients undergoing preoperative evaluation for glioma resection compared with more routinely applied correction methods such as realignment or motion scrubbing. MATERIALS AND METHODS Thirty-five functional runs (both motor and language) in 12 consecutive patients with glioma were analyzed retrospectively by double-blind review. Data were processed and compared with the following: 1) realignment alone, 2) motion scrubbing, 3) independent component analysis denoising, and 4) both independent component analysis denoising and motion scrubbing. Primary outcome measures included a change in false-positives, false-negatives, z score, and diagnostic rating. RESULTS Independent component analysis denoising reduced false-positives in 63% of studies versus realignment alone. There was also an increase in the z score in areas of true activation in 71.4% of studies. Areas of new expected activation (previous false-negatives) were revealed in 34.4% of cases with independent component analysis denoising versus motion scrubbing or realignment alone. Of studies deemed nondiagnostic with realignment or motion scrubbing alone, 65% were considered diagnostic after independent component analysis denoising. CONCLUSIONS The addition of independent component analysis denoising of fMRI data in preoperative patients with glioma has a significant impact on data quality, resulting in reduced false-positives and an increase in true-positives compared with more commonly applied motion scrubbing or simple realignment methods.

Abstract
Outcome of children with nephrotic syndrome has continued to improve over time. However minimal data exist to describe health-related quality of life in children with nephrotic syndrome. This cross sectional study was conducted over a period of six months to assess the health related quality of life in children with nephrotic syndrome in the Department of Pediatric Nephrology, Dhaka Medical College Hospital, Bangladesh. Fifty children (age ranged 2-12 years) with nephrotic syndrome who had three or more relapses diagnosed at least one year back receiving treatment and on follow up were included in this study. Quality of Life scores were collected using Bengali translated instruments- the Pediatric Quality of Life Inventory™ (PedsQL™) version 4.0 Generic Scale and the Pediatric Quality of Life Questionnaire for Nephrotic Syndrome proxy-report from parents. Medical data and Demographic data were collected from medical records, and from parents in outpatient department or hospital ward. Interviews of eligible guardians were performed individually to collect quality of life (QoL) scores. Among 50 children, mean±SD age of the children was 7±2.92 years. Most children were male (58%). Female parents respondent during interview were 62%, most parents (48%) were very poor in socioeconomic condition. Most children had frequent relapses (60%). Median time since diagnosis was 2 years. Regarding PedsQL scores, child age with physical summary score (p value <0.001), child age with social summary score (p value 0.003), frequent relapse with kidney disease summary score (p value 0.04) and time since diagnosis (p value <0.001) were statistically significant. In conclusion physical and social summary score were worst. Frequent relapse found to be an important factor in impaired QoL. Prolonged duration of the disease activity was associated with significant impairment of QoL.

Abstract
This prospective study was conducted to compare the outcome of endoscopic sinus surgery (ESS) using SNOT-20 score chart (subjective) and Lund & Kennedy scoring chart (objective) and carried out in the Department of Otolaryngology & Head-Neck Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Dhaka Medical College Hospital (DMCH) & Shaheed Suhrawardy Medical College Hospital (ShSMCH) from July 2010 to March 2012. Total 73 admitted cases were selected purposively for ESS, male 53(72.60%) and female 20(27.40%). Among the study participants 10(13.7%) had chronic rhinosinusitis with bilateral polyposis and 26(35.62%) had chronic rhinosinusitis with unilateral polyposis and 12(16.44%) had bilateral chronic rhinosinusitis without polyposis and 25(34.25%) had unilateral chronic rhinosinusitis without polyposis. Surgical procedures done among the patients were Uncinectomy (infundibulectomy), Middle Meatal Antrostomy; Anterior Ethmoidectomy; Sphenoidotomy, Associated septoplasty and no significant per or post operative complications were noted. In Chronic rhinosinusitis (CRS) with polyposis pre operative SNOT-20 mean and SD 1.322±0.341 and post ESS snot-20 mean and SD 0.3472±0.0755, CRS without polyposis pre operative SNOT-20 mean and SD 0.9297±0.86 and post ESS SNOT-20 mean and SD 1986±0.0558. In CRS with polyposis pre operative Lund & Kennedy score of endoscopic assessment, mean and SD 5.333±2.255 and post ESS mean and SD 1.31±1.009. In CRS without polyposis pre op Lund & Kennedy score mean and SD 3.108±1.074 and post ESS mean and SD 0.76±0.641.Post ESS SNOT-20 in CRS with Polyposis, 't' test result was 27.58 which was significant (p<0.001) and in CRS without Polyposis was 21.622 which was significant (p<0.001); Lund & Kennedy Score of post ESS in CRS with Polyposis 't' test result was 7.763 which was significant (p<0.001), CRS without Polyposis was 7.177 which was significant (p<0.001).This implies that outcome of ESS in treatment of CRS with or without polyposis had statistically significant role. Symptomatic relief and quality of life improvement after ESS was compared by improvement in post operative scores of SNOT-20 & Lund-Kennedy score of endoscopic assessment. Post operative lower values were considered to be better improvement status. The results of the study suggests that ESS performed in Chronic Rhinosinusitis without Polyposis cases, relief of symptoms and quality of life improved was better than Chronic Rhinosinusitis with Polyposis cases postoperatively as compared by SNOT-20 and Lund & Kennedy score of endoscopic assessment.

Abstract
Immune reactivity between Mycobacteria and human antigens can play an important role in the pathogenesis of autoimmune disease. We report a case of Graves's disease and tuberculous lymphadenitis to explain the mechanism of correlation between immune-mediated diseases and tuberculosis and to raise awareness of the importance of screening for TB in this context, especially in endemic country. Screening for latent TB at immune mediated disease diagnosis and regular timely screening thereafter may be beneficial.

Abstract
INTRODUCTION Malignant lymphoma of the female genital tract is quite rare and its presentation may resemble that of other, more common tumors, causing confusion for clinicians. CASE HISTORY The authors report three patients with a non-Hodgkin lymphoma (NHL) involving the female genital tract: two cases involved the ovary and one involved the uterus. In all patients, the genital tract was the initial site of clinical presentation of a B cell lymphoma. One patient was diagnosed postoperatively and subsequently received chemotherapy; the other two patients were diagnosed by imaging-guided biopsy and were successfully managed by chemotherapy without resection surgery. Two patients were alive, without evidence of disease, and one patient was alive with disease at their most recent follow-up visit. CONCLUSION The authors' experience emphasizes that lymphoma should be in the differential diagnosis of pelvic gynecological malignancies, and its clinical, biological, and radiological signs must be actively sought. Imaging-guided biopsy should be performed to avoid unnecessary surgery.

This cross sectional study was carried out in the department of gastroenterology, BIRDEM, Dhaka from January 2010 to May 2011 to determine the role of ascitic fluid ADA and serum CA-125 in the diagnosis of clinically suspected tubercular peritonitis. Total 30 patients (age 39.69 ± 21.26, 18M/12F) with clinical suspicion of tuberculosis peritonitis were included in this study after analyzing selection criteria. Laparoscopic peritoneal biopsy with 'histopathological diagnosis' was considered gold standard against which accuracics of two biomarkers (ADA & CA-125) were compared. Cut off value of ADA and CA-125 are 24 u/l, 35 U/ml respectively. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ADA as a diagnostic modality in tuberculos peritonitis were 87.5%, 83.33%, 95.45%, 62.5% and 86.67% respectively where as CA-125 was found to have 83.33% sensitivity, 50% specificity, 86.9% positive predictive value, 42.85% negative predictive value and 76.6% accuracy. Both biomarkers are simple, non-invasive, rapid and relatively cheap diagnostic test where as laparoscopy is an invasive procedure, costly & requires trained staff and not without risk and also not feasible in all the centre in our country. So ascitic fluid ADA and serum CA-125 are important diagnostic test for peritoneal tuberculosis.

Abstract
Fowl adenovirus-4 is an infectious agent causing Hydropericardium syndrome in chickens. Adenovirus are non-enveloped virions having linear, double stranded DNA. Viral genome codes for few structural and non structural proteins. 100K is an important non-structural viral protein. Open reading frame for coding sequence of 100K protein was cloned with oligo histidine tag and expressed in Escherichia coli as a fusion protein. Nucleotide sequence of the gene revealed that 100K gene of FAdV-4 has high homology (98%) with the respective gene of FAdV-10. Recombinant 100K protein was expressed in E. coli and purified by nickel affinity chromatography. Immunization of chickens with recombinant 100K protein elicited significant serum antibody titers. However challenge protection test revealed that 100K protein conferred little protection (40%) to the immunized chicken against pathogenic viral challenge. So it was concluded that 100K gene has 2397 bp length and recombinant 100K protein has molecular weight of 95 kDa. It was also found that the recombinant protein has little capacity to affect the immune response because in-spite of having an important role in intracellular transport & folding of viral capsid proteins during viral replication, it is not exposed on the surface of the virus at any stage.

Abstract
We investigated an outbreak of jaundice in urban Bangladesh in 2010 to examine the cause and risk factors and assess the diagnostic utility of commercial assays. We classified municipal residents reporting jaundice during the preceding 4 weeks as probable hepatitis E cases and their neighbours without jaundice in the previous 6 months as probable controls. We tested the sera collected from probable cases and probable controls for IgM anti-hepatitis E virus (HEV), and the IgM-negative sera for IgG anti-HEV using a commercial assay locally. We retested the IgM-positive sera for both IgM and IgG anti-HEV using another assay at the Centre for Disease Control and Prevention (CDC), USA. Probable cases positive for IgM anti-HEV were confirmed cases; probable controls negative for both IgM and IgG anti-HEV were confirmed controls. We explored the local water supply and sanitation infrastructure and tested for bacterial concentration of water samples. Probable cases were more likely than probable controls to drink tap water (adjusted odds ratio: 3.4; 95% CI: 1.2-9.2). Fifty-eight percentage (36/62) of the case sera were IgM anti-HEV positive; and 75% of the IgM-positive samples were confirmed positive on retesting with another assay at CDC. Compared to confirmed controls, cases confirmed using either or both assays also identified drinking tap water as the risk factor. Two tap water samples had detectable thermotolerant coliforms. Research exploring decentralized water treatment technologies for sustainable safe water might prevent HEV transmission in resource-poor cities. Detection of serological markers in a majority of probable cases implied that available diagnostic assays could adequately identify HEV infection during outbreaks.

Abstract
Currently licensed typhoid vaccines are based on Vi capsular polysaccharides. Recent molecular reports from typhoid endemic countries state that Salmonella enterica serovar Typhi (S. Typhi) Vi negative strains occur naturally and cause typhoid fever which is indistinguishable from disease caused by Vi positive strains. Vaccine based on Vi polysaccharide may not protect patients if the invading S. Typhi are negative for Vi. The lipopolysaccharide (LPS) is an essential component of S. Typhi outer membrane in which O-specific polysaccharide (OSP) is a protective antigen and universal candidate for vaccine development. In this study, S. Typhi Vi negative isolates were discriminated from Vi positive isolates through a duplex PCR using primers of fliC-d (599bp) and tviA (495bp) genes. The LPS of S. Typhi Vi negative isolates was extracted by hot phenol method and OSP was purified by core hydrolysis. The yield of extracted LPS was 91 mg/L and that of purified OSP was 49.14 mg/L of culture broth. LPS showed ladder like appearance by zinc imidazole staining following SDS-PAGE. Whole cell challenged mice sera were used for in vitro antigenicity evaluation of the purified LPS and OSP. The antigenicity was found adequate by immunodiffusion assay. To our knowledge, this is the first report of purification and antigenic evaluation of LPS of a Vi negative S. Typhi isolate. The purified OSP from S. Typhi Vi negative isolate may be coupled with a carrier protein to produce universal low cost conjugate vaccine candidates for use in typhoid endemic regions.

Abstract
This study was done to find the commonest variety of sinonasal malignancy and its association with sex.This cross-sectional study was conducted in the Department of Otolaryngology - Head & Neck Surgery Department, Dhaka Medical College & Hospital and in the Department of Otolaryngology - Head & Neck Surgery Department, Bangabandhu Sheikh Mujib Medical University between January 2009 and December 2009. A total of 146 cases of sinonasal malignancy were consecutively included in the study. The diagnosis was confirmed by histopathology. The mean age was 47.8 years (range: 22-75 years). Over three-quarters (77%) of the patients were male with male to female ratio being 3:1. Nearly one-third (30.8%) of the patients was farmer and over one-third (36.3%) was illiterate. The right sinonasal region was involved in 48.6% cases, left sinonasal region in 39% and both sinonasal region in 12.4% cases. Histopathological diagnosis of sinonasal malignancy revealed that squamous cell carcinoma accounted for 82.9% of sinonasal malignancies, 9.6% adenocarcinoma and the rest were olfactory neuroblastoma, adenoid cystic carcinoma and mucoepidermoid carcinoma. About 96.6% of the tumours involved nasal cavity, 97.9% maxillary sinuses, 17.8% frontal sinuses, 48.6% ethmoidal sinuses and 13% sphenoid sinuses. Over 80% of patients were smoker. Exposure to wood dust was found in 26% of cases. Lather tanning in 4.8% of cases and welding in 4.1% of cases. T staging shows that nearly half (48.6%) of the patients lesion was T2, 29.5% T3, 19.9% T4 and 2.1% T1. None of the patients exhibited lymph node involvement or distant metastasis. Males tend to develop squamous cell carcinoma significantly more than the females with risk of acquiring squamous cell carcinoma being nearly 3(1.1-7.1) times higher in male than that in female (p=0.022). The study concludes that the most common histopathological variety of sinonasal malignancy is squamous cell carcinoma and males are prone to develop this malignancy more frequently than the females.

Abstract
OBJECTIVES To assess the association between parental education and under-five mortality, using the Integrated Management of Childhood Illness (IMCI) data from rural Bangladesh. It also investigated whether the association of parental education with under-five mortality had changed over time. STUDY DESIGN This study was nested in the IMCI cluster randomized controlled trial. METHODS Participants considered for the analysis were all children aged under five years from the baseline (1995-2000) and the final (2002-2007) IMCI household survey. The analysis sample included 39,875 and 38,544 live births from the baseline and the final survey respectively. The outcome variable was under-five mortality and the exposure variables were mother's and father's education. Data were analysed with logistic regression. RESULTS In 2002-2007, the odds of the under-five mortality were 38% lower for the children with mother having secondary education, compared to the children with uneducated mother. For similar educational differences for fathers, at the same time period, the odds of the under-five mortality were 16% lower. The association of mother's education with under-five mortality was significantly stronger in 2002-2007 compared to 1995-2000. CONCLUSIONS Mother's education appears to have a strong and significant association with under-five mortality, compared to father's education. The association of mother's education with under-five mortality appears to have increased over time. Our findings indicate that investing on girls' education is a good strategy to combat infant mortality in developing countries.

Abstract
OBJECTIVE To determine the prevalence of tuberculosis (TB) drug resistance in Bangladesh. DESIGN Weighted cluster sampling among smear-positive cases, and standard culture and drug susceptibility testing on solid medium were used. RESULTS Of 1480 patients enrolled during 2011, 12 falsified multidrug-resistant TB (MDR-TB) patients were excluded. Analysis included 1340 cases (90.5% of those enrolled) with valid results and known treatment antecedents. Of 1049 new cases, 12.3% (95%CI 9.3-16.1) had strains resistant to any of the first-line drugs tested, and 1.4% (95%CI 0.7-2.5) were MDR-TB. Among the 291 previously treated cases, this was respectively 43.2% (95%CI 37.1-49.5) and 28.5% (95%CI 23.5-34.1). History of previous anti-tuberculosis treatment was the only predictive factor for first-line drug resistance (OR 34.9). Among the MDR-TB patients, 19.2% (95%CI 11.3-30.5; exclusively previously treated) also showed resistance to ofloxacin. Resistance to kanamycin was not detected. CONCLUSION Although MDR-TB prevalence was relatively low, transmission of MDR-TB may be increasing in Bangladesh. MDR-TB with fluoroquinolone resistance is rapidly rising. Integrating the private sector should be made high priority given the excessive proportion of MDR-TB retreatment cases in large cities. TB control programmes and donors should avoid applying undue pressure towards meeting global targets, which can lead to corruption of data even in national surveys.

Abstract
An attempt is made to understand uranium series disequilibrium in unconformity proximal related uranium mineralisation in Chenchu colony area, Guntur district, Andhra Pradesh, India. The uranium mineralization in Chenchu colony is the western continuity of the Koppunuru uranium deposit and predominantly hosted by gritty quartzite/conglomerate, which occasionally transgresses to underlying basement granite/basic rock. Disequilibrium studies are based on borehole core samples (35 boreholes, No. of samples=634) broadly divided in two groups of cover rocks of Banganapalle formation (above unconformity) and basement granites (below unconformity). Linear regression coefficient between uranium and radium is 0.95, which reflects excellent correlation and significant enrichment of parent uranium. Disequilibrium studies have indicated predominant disequilibrium in favour of parent uranium (35%), which is probably due to the weathering process causing migration of some of the radionuclides while dissolution of minerals due to groundwater action might have also played a significant role. Further, escape of radon might have accentuated the disequilibrium factor resulting in an increase in the grade of the mineralization. This is well corroborated by the presence of fractures and faults in the study area providing channels for radon migration/escape.

Abstract
AIM The objective of the study was to evaluate the effect of deep litter housing and fermented feed on carcass characteristics and meat quality of crossbred Hampshire pigs. MATERIALS AND METHODS Forty-eight weaned crossbred Hampshire piglets of 2 months age (24 males and 24 females) were selected for the experiment. The piglets were randomly assigned into 4 homogenous experimental groups with 6 males and 6 females each: E1; reared on a conventional housing and fed with a fermented diet, E2; reared on a deep litter housing system and fed with a fermented diet, E3; reared on a deep litter housing system and fed with a conventional diet and C; reared on a conventional housing system and fed with a conventional diet. The study was continued up to 32 weeks of age and at the end of this period, 6 animals (3 males and 3 females) from each experimental group were slaughtered to evaluate carcass traits and meat quality characteristics. RESULTS Pre-slaughter weight, hot carcass weight, and dressing percentage were significantly (p<0.01) affected by feeding fermented diet and deep litter housing while carcass traits, i.e., carcass length, backfat thickness, and loin eye area were not affected. The edible offal; liver and heart weight (p<0.05) differed significantly while kidney weight showed no difference. The inedible offal; head weight (p<0.01) and lung weight revealed a significant difference (p<0.05) while spleen and stomach weight showed no difference among the experimental groups. The wholesale cuts and meat: bone ratio of pigs also differed significantly among the groups. Morphometry of small and large intestine also showed a significant difference. Chemical composition of pork viz., moisture and total ash content was influenced by the treatment, while crude protein and ether extract content were not affected. Mineral composition of pork also showed no significant difference. Color characteristics of Longissimus dorsi muscle showed a significant difference in L* and a* value while parameter b* was not affected. The tenderness of meat showed significant difference among the groups (p<0.01). CONCLUSION Crossbred Hampshire pigs being reared on fermented feed and deep litter housing could produce highlygraded carcass and improvement in meat quality.

Abstract
Breast tuberculosis is a rare form of tuberculosis. Moreover the disease is often overlooked and misdiagnosed as carcinoma or pyogenic abscess. Reports on breast tuberculosis have been few; reported incidence of breast tuberculosis amongst the total number of mammary conditions varies between 0.1 and 4 percent. Bilateral involvement is still more uncommon (3%). Here we report 3 cases of adult female ranging from 27 to 35 years who presented with 1 to 4 months history of firm lumps in both breasts and no axillary lymphadenopathy. Fine needle aspiration cytology (FNAC) of breast lump in all 3 cases were done but in 1 case showed evidence of tubercular mastitis and other 2 cases findings were inconclusive. Subsequent Excisional Biopsy of those 2 cases showed features of tuberculosis. All 3 were prescribed with four drug anti-tubercular treatments continued for 12 months in 2 cases and 9 months in other case depending upon their response. The lumps disappeared and ulcer healed after anti-tubercular treatment.

Abstract
Molecular technique was used to investigate the prevalence of virulent diarrheic genes in pathogenic Escherichia coli and their antibiotic sensitivity patterns. A hundred samples from 100 different diarrheic calves from mid-north-western part of Bangladesh were screened for the presence of virulence factors associated with diarrhea. Following isolation and identification on the basis of cultural, morphological and biochemical properties, the presence of the virulence genes such as eaeA, bfpA, elt, est, stx1 and stx2 were examined using PCR. Antimicrobial susceptibility of 57 E. coli was determined by agar disk diffusion method for 8 antimicrobial agents. Out of 100 samples 57 (57%) were found to be positive for E. coli and their distribution rates according to their age, breed and sex were 66.7% ( 6 days old ), 85.7% (Sahiwal breed) and in 64.2 % (female calves) respectively. Among 57 E. coli isolates, only 16 isolates were analyzed for the detection of the said genes. Among them, only eaeA gene was detected in 2 E. coli isolates (12.5 %). Antibiotic resistance patterns revealed that Oxacillin, Rifampicin and Penicillin were 100% resistant followed by Erythromycin which was more than 80% resistant. In case of Amoxicillin and Tetracycline, about 59.65% and 61.40% were found to be resistant respectively whereas all 57 E. coli isolates showed moderately susceptible (30%) to Cefuroxime, a second generation Cephalosporin. Therefore, none of the eight antimicrobials studied can not be recommended as single best therapeutic agent for the treatment of neonatal calf diarrhea. In addition, this study indicated that diarrhea in calves in these locations can be ascribed to mainly Enteropathogenic E. coli (EPEC) which was atypical (only contained the eaeA genes but not bfpA). However, further studies are necessary to characterize the isolated eaeA gene positive E. coli by serotyping, tissue culture assay and other molecular techniques to find out the potentiality of those virulent genes contributing pathogenicity of E. coli causing diarrhea in calves.DOI: http://dx.doi.org/10.3329/bjvm.v13i1.23716Bangl.

Abstract
A study was conducted in the Laboratory of Animal Husbandry and Veterinary Science, University of Rajshahi, Rajshahi, Bangladesh, during March, 2011 to February, 2012. The aim of this study was to determine the effects of temperature, humidity and rainfall in different months on the prevalence of haemonchosis of goats in Rajshahi, Bangladesh. A total of 720 samples were examined, of these (416) 57.8% goats were found positive for Haemonchus spp. infection. The highest prevalence was observed in the month of July (82.1 %) followed by August (79.7 %) and lowest in the January (28.3 %) followed by February (38.7 %). It was also observed that temperature (29.8°?), relative humidity (86%) and rainfall (146.0 mm) in the month of July was favourable for the egg laying, hatching and survival of infective larvae on the pasture. On the other hand, all the factors like temperature, humidity and rainfall was recorded lowest as 17.5°?, 79%, 5.5 mm respectively which was unfavourable for the reproduction and survival of infective larvae in the month of the January. The current study revealed that haemonchosis is an important and common parasitic disease and requires special attention for its control. The prevalence among different months when compared statistically (Chi-square test and DMRT) revealed significant (P=0.001) differences. So, it is concluded that, month of the year, temperature, humidity and rainfall has significance effect on the prevalence of haemonchosis in goats. Considering those factors control should be carried out in and around Bangladesh to improve our goat production.DOI: http://dx.doi.org/10.3329/bjvm.v13i1.23713Bangl. J. Vet. Med.

Abstract
Repeated forced swim (FS) conditioning enhances nociceptive responses to temporomandibular joint (TMJ) stimulation in female rats. The basis for FS-induced TMJ hyperalgesia remains unclear. To test the hypothesis that serotonin 3 receptor (5HT3R) mechanisms contribute to enhanced TMJ nociception after FS, ovariectomized female rats were treated with estradiol and subjected to FS for three days. On day 4, rats were anesthetized with isoflurane and TMJ-responsive neurons were recorded from superficial and deep laminae at the trigeminal subnucleus caudalis/upper cervical (Vc/C1-2) region and electromyographic (EMG) activity was recorded from the masseter muscle. Only Vc/C1-2 neurons activated by intra-TMJ injections of ATP were included for further analysis. Although neurons in both superficial and deep laminae were activated by ATP, only neurons in deep laminae displayed enhanced responses after FS. Local application of the 5HT3R antagonist, ondansetron (OND), at the Vc/C1-2 region reduced the ATP-evoked responses of neurons in superficial and deep laminae and reduced the EMG response in both sham and FS rats. OND also decreased the spontaneous firing rate of neurons in deep laminae and reduced the high-threshold convergent cutaneous receptive field area of neurons in superficial and deep laminae in both sham and FS rats. These results revealed that central application of a 5HT3R antagonist, had widespread effects on the properties of TMJ-responsive neurons at the Vc/C1-2 region and on jaw muscle reflexes under sham and FS conditions. It is concluded that 5HT3R does not play a unique role in mediating stress-induced hyperalgesia related to TMJ nociception.

Unusually High Mortality in Waterfowl Caused by Highly Pathogenic Avian Influenza A(H5N1) in Bangladesh. Transbound Emerg Dis 2015; 64:144-156.

Abstract
Mortality in ducks and geese caused by highly pathogenic avian influenza A(H5N1) infection had not been previously identified in Bangladesh. In June-July 2011, we investigated mortality in ducks, geese and chickens with suspected H5N1 infection in a north-eastern district of the country to identify the aetiologic agent and extent of the outbreak and identify possible associated human infections. We surveyed households and farms with affected poultry flocks in six villages in Netrokona district and collected cloacal and oropharyngeal swabs from sick birds and tissue samples from dead poultry. We conducted a survey in three of these villages to identify suspected human influenza-like illness cases and collected nasopharyngeal and throat swabs. We tested all swabs by real-time RT-PCR, sequenced cultured viruses, and examined tissue samples by histopathology and immunohistochemistry to detect and characterize influenza virus infection. In the six villages, among the 240 surveyed households and 11 small-scale farms, 61% (1789/2930) of chickens, 47% (4816/10 184) of ducks and 73% (358/493) of geese died within 14 days preceding the investigation. Of 70 sick poultry swabbed, 80% (56/70) had detectable RNA for influenza A/H5, including 89% (49/55) of ducks, 40% (2/5) of geese and 50% (5/10) of chickens. We isolated virus from six of 25 samples; sequence analysis of the hemagglutinin and neuraminidase gene of these six isolates indicated clade 2.3.2.1a of H5N1 virus. Histopathological changes and immunohistochemistry staining of avian influenza viral antigens were recognized in the brain, pancreas and intestines of ducks and chickens. We identified ten human cases showing signs compatible with influenza-like illness; four were positive for influenza A/H3; however, none were positive for influenza A/H5. The recently introduced H5N1 clade 2.3.2.1a virus caused unusually high mortality in ducks and geese. Heightened surveillance in poultry is warranted to guide appropriate diagnostic testing and detect novel influenza strains.

Abstract
OBJECTIVE To estimate the costs incurred by patients during the intensive and continuation phases of the current 6-month tuberculosis (TB) regimen in Bangladesh and Tanzania, and thus identify potential benefits to patients of a shorter, 4-month treatment regimen. DESIGN The validated Stop TB patient cost questionnaire was adapted and used in interviews with 190 patients in the continuation phase of treatment with current regimens. RESULTS In both countries, overall patient costs were lower during 2 months of the continuation phase (US$74 in Tanzania and US$56 in Bangladesh) than during the 2 months of the intensive phase of treatment (US$150 and US$111, respectively). However, continuation phase patient costs still represented 89% and 77% of the 2-month average national income in the respective countries. Direct travel costs in some settings were kept low by local delivery system features such as community treatment observation. Lost productivity and costs for supplementary foods remained significant. CONCLUSIONS Although it is not a straightforward exercise to determine the exact magnitude of likely savings, a shorter regimen would reduce out-of-pocket expenses incurred by patients in the most recent 2 months of the continuation phase and allow an earlier return to productive activities.

[PMID: 25444051 PMCID: PMC4282947 DOI: 10.1016/j.jpag.2014.01.109] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2013] [Revised: 01/28/2014] [Accepted: 01/31/2014] [Indexed: 11/26/2022]
Abstract
STUDY OBJECTIVE To assess the level of HPV knowledge among low income, minority mothers with a child between the ages of 9-17 y. DESIGN Women who sought care at a university-based clinic and had at least 1 child aged 9 to 17 years were approached. A total of 638 mothers were recruited. Only those who had heard of HPV were included in the correlation analyses (n = 468). MAIN OUTCOME MEASURES HPV knowledge was assessed utilizing a self-administered questionnaire consisting of 20 questions. RESULTS There were differences between those who had heard of HPV and those who had not. More of those who had not heard of HPV were Hispanic (63%), low-income (89%), and did not graduate high school (59%). Of those who had heard of HPV, the majority did not answer 50% of questions correctly. Few knew the vaccine could prevent genital warts (19.7%). Factors independently associated with HPV knowledge included age, personal history of HPV, cervical dysplasia or cervical cancer, acquiring knowledge from ≥ 2 sources, having known someone with HPV or cervical cancer, having seen a brochure on the vaccine, and having seen an advertisement for the vaccine. CONCLUSIONS Knowledge regarding HPV is low among low-income women with children in the target age range for HPV vaccination. Increased awareness should focus on genital warts and other cancers, since this population has virtually no knowledge of other health outcomes related to HPV infection. Educational programs tailored to this population need to be developed to increase vaccination.
