ABSTRACT
Effect of Bis-2ethylhexyl phthalate (DEHP) on commercially important tropical fish pearl spot has not been demonstrated at environmental concentrations along with depuration. The species is estuarine, juvenile and difficult to maintain but widely consumed and well distributed in tropical estuaries. Antioxidant activity of SOD, CAT and GPx was enhanced on all exposure days for gill and muscle suggesting high oxidative stress, except on day 5. Detoxifying enzyme-GST behaved differentially in gill and muscle tissue after depuration, depicting inhibited activity of GST in gill leading to lipid peroxidation. However, the muscle tissue was able to recover from stress after 7 days of depuration with the help of detoxifying enzymes. Overcompensation of antioxidant activity was observed over disruption of homeostasis defining hormesis effect. Integrated biomarker (IBR) index depicted high toxicity during entire exposure time, but after depuration, gill could not mediate LPO at lowest concentration (10 µg/l) while muscle tissue recovered, suggesting persistence of stress in gill.

Plasma processing appears to be the mainstay of food preservation in the present day due to its effectiveness in controlling microorganisms at low temperatures. Legumes are usually soaked before cooking. Six chickpea varieties (Kripa, Virat, Vishal, Vijay, Digvijay, and Rajas) were soaked in distilled water at room temperature, and Peleg model was fitted after plasma treatment. Cold plasma treatment was used at 40, 50 and 60 Watt with exposure times of 10, 15 and 20 min. K1 (Peleg rate constant) consistently decreased from 32.3 to 4.3 × 10-3 (h % - 1) for all six chickpea cultivars, indicating an increased water absorption rate with increasing plasma power and treatment time. It was lowest in 60 W 20 min plasma treatment in Virat cultivar. K2 (Peleg capacity constant) ranged from 9.4 to 12 × 10-3 (h % - 1) for all six chickpea cultivars. Thus, plasma treatment showed no effect on water uptake capacity (K2), as it did not increase or decrease consistently with increasing plasma power and treatment time. Fitting the Peleg model successfully revealed the correlation between the water absorption of chickpea cultivars. The model fit ranged from R2 ≥ 0.9873 to 0.9981 for all six chickpea cultivars.

Cold plasma has proven itself as a promising method of food preservation by controlling food spoilage bacteria at very low temperatures. It is showing potential for insect control. Synthetic pesticides are mostly used to control Callosobruchus chinensis L. (Chrysomelidae: Coleoptera) to which it has developed resistance. The prospective potential of cold plasma treatment to control pulse beetle infestation of chickpea in the storage for about four years of plasma treatment was studied. The four chickpea cultivars were treated with cold plasma at different power 40, 50, and 60 W each for 10, 15, 20 min. Plasma treated and untreated chickpeas were stored in an airtight ziplock pouch. At regular intervals, the grains were observed for infestation. It was found most effective in controlling the pulse beetle infestation of treated chickpea samples. While plasma untreated chickpeas were attacked and damaged mostly by pulse beetle within the first quarter of the storage study. To avoid the problems created by the use of pesticides cold plasma treatment is found to be the best alternative in the protection of chickpea invasion by pulse beetle during a longer storage period. The findings in the present research may be used for the preparation of legumes which may also soak and cook faster like quick-cooking legumes and preserved for years without invasion of pulse beetle.
ABSTRACT
Guillain-Barre syndrome (GBS) is related with significant morbidity and also mortality. Little is known about the long term outcome of GBS patients who survived. The objective of this study is to determine the lasting outcome and consequences of GBS patients. This is a cross-sectional study of patients who diagnosed GBS and managed at the Intensive Care Unit of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2004 to December 2017. All survived patients were invited for a structured interview, questionnaires, and full neurologic exam to record their current clinical condition focused on complaints and symptoms, neurological deficits, disabilities, behaviour, and quality of life. Thirty-eight patients participated, with a median age of 20 years (range 4-39 years) and a median interviewed time of 7 years (range 1-13 years). Residual complaints were reported by 24(63%) patients, including paresthesias (10.5%), unsteadiness of gait (37%), painful hands or feet (29%), and severe fatigue (13%). Questionnaires identified a wide range of behavioural problems. Most Patients showed good recovery of neurological deficits after GBS, but many have persisting long-term residual complaints and symptoms that may lead to psychosocial problems interfering with participation in daily life.

OBJECTIVE: The aim of this study was to evaluate the level of knowledge about gestational diabetes mellitus (GDM) in Bangladeshi people. STUDY DESIGN: Cross-sectional study. METHODS: This study involving 1374 participants was conducted in 15 outpatient clinics of Diabetic Association of Bangladesh and its affiliated associations, Bangabandhu Sheikh Mujib Medical University and four medical college hospitals in Bangladesh from August 2015 to December 2015. A pretested interviewer-administered questionnaire was used to obtain information related to sociodemographic status, level of education, types of profession, and medical history. The questionnaire included eight questions on GDM. Level of knowledge (mean ± 1 standard deviation [SD]) was categorized as poor, average, and good. Descriptive, Chi-squared, and regression analysis were performed to express the results. RESULTS: Of total knowledge score of 8, participants' mean knowledge score (±SD) was 2.7 ± 1.5. The levels of good, average, and poor knowledge were 26.3%, 63.1%, and 10.6%, respectively. In multivariate analysis, participants aged below 30 years (P < 0.001), male gender (P < 0.001), high-income group (P < 0.001), having university education (P < 0.001), health professionals (P < 0.001), capital Dhaka city residents (P < 0.001), those with family history of diabetes (P = 0.007), and participants with diabetes (P = 0.007) were found to be significantly associated with the good knowledge score. CONCLUSIONS: Participants in this study had average knowledge about GDM. New innovative strategies should be developed to improve the knowledge of GDM among health professionals and general population.

Ureteral stent placement is a common procedure in urologic practice. Forgotten, encrusted D/J stents represent a difficult problem for urologists. The major complications are infection, impaired renal function, migration, encrustation, stone formation and multiple fragmentation of stent. A consensus on the best therapeutic approach is still lacking. Here we present our experience with endoscopic management of this challenging problem and discuss the multimodal endourologic approaches for treating forgotten, encrusted ureteral stents. In this prospective observational study 29 patients (17 males and 12 females), age ranges from 19 to 57 years with 35 (23 unilateral and 6 bilateral) encrusted ureteral stents, indwelling for 5 to 78 months were treated in the Department of Urology, Dhaka Medical College Hospital (DMCH), Dhaka, Bangladesh from January 2011 to December 2015. All patients were evaluated by urine culture and sensitivity, renal function. Stent encrustation and the associated stone burden were estimated by plain radiograph. Treatment decisions were made based on the clinical presentation, degree of encrustation, stone burden and image findings. Patients were followed up to 06 months. The main indications for stenting were pyelolithotomy, ureterolithotomy, ureteroneocystostomy, URS and pyeloplasty. In kidney, mild encrustation was common (48.3%) moderate encrustation (27.6%) was less common; where as in ureter and urinary bladder, moderate encrustation was common (72.4% and 44.8%). Over three-quarters 22(75.9%) of the patients underwent extracorporeal shockwave lithotripsy (ESWL) and 10(34.5%) percuteneousnephrostomy preoperatively. Retrograde ureteroscopy with intracorporeal lithotripsy (URS & ICPL) was done in 29 cases and cystolitholapaxy (CLL) in 16(55%) cases. Cystolithotomy & PCNL was rarely done. The mean number of procedures was 2.8 (range: 1-7). Using these multimodal approaches, all stents and associated stones were eventually removed with minor complications. Nine patients developed haematuria, 5 urosepsis and 4 both haematuria & urosepsis. Multimodal endourologic approaches can safely remove forgotten, encrusted D/J stents, if treatment is tailored to the volume of encrustation and associated stone. Imaging evaluation and documentation of negative urine culture are imperative prior to any attempt to remove the stent.

Medical education in Bangladesh is poorly assessed and there is a general lack of documented knowledge about the challenges facing this field and the needs for its development. It was Cross-sectional descriptive type of study carried out among the teachers of two public (Sir Salimullah Medical College, Dhaka and Sher-E-Bangla Medical College, Barisal) and two non-government Medical Colleges (Northern Medical College, Dhaka and IBN Sina Medical College, Dhaka) during the period of July 1, 2011 to June 30, 2012 to explore their views regarding the training or course in medical education. The sample size was 204 who were selected purposively. The data were collected by a semi-structured and self-administered questionnaire. From the study it was revealed that majority 201(98.5%) of respondents showed their interest for training or course on medical education. Among them 123(61.2%) preferred a regular course, 58(28.8%) desired for training program and 20(9.9%) for refresher training on medical education. Most 83(67.4%) of the respondents agreed that there are barriers to participate in a training or course on medical education. Thirty four (43.6%) expressed their opinion that the duration of the training should be at least three months.

Worldwide a large number of patients have been suffering from breast lump and this trend is gradually increasing. It is difficult to determine whether a lump is benign or malignant from clinical assessment. Thus the need for microscopic tissue analysis arises. This study was designed to determine the value of fine needle aspiration cytology in the diagnosis of breast lumps and to compare the result of FNAC with histopathological diagnosis to assess its accuracy. A prospective study in the period of January 2009 to December 2010 was done. One hundred and ten (110) patients who came to the Department of Surgery in Mymensingh Medical College Hospital, Bangladesh in two years for their palpable breast masses were chosen for the study. There were 70(63.63%) benign, 33(30.00%) malignant and 07(6.36%) suspicious smears in FNAC. Inadequate samples were repeated. The number of repeats increased the diagnostic accuracy of aspirates which is statistically significant when compared with histopathology. In histopathology Invasive ductal carcinoma was the most commonly reported lesion with maximum incidence in the 4th, 5th, and 6th decades followed by invasive lobular carcinoma and other malignant lesions. FNAC serves as a rapid, economical and reliable tool for the diagnosis of palpable breast lesions and its reliability is influenced by the skillness of the aspirator. So physician should use this tool with clinical experience.

Neonatal Priapism is a rare condition and its causes differ from that in childhood and adult. Management also is challenging as the ultimate goal is the preservation of normal erectile function. Most of the cases are idiopathic. A spontaneous detumescence occurs in majority of cases, so initially conservative non-surgical treatment is advocated. Here we report a case of a newborn presenting with priapism on the 1st day of life. Detumescence was achieved on the 8th day of life with conservative treatment.

Clinical and Biochemical characteristics age, central obesity, Glucose intolerance, lipid abnormality, thyroid function, prolactin level, clinical signs & symptoms and ultrasonographic ovarian feature of 70 women were studied and prevalence of hyper-prolactinemia, hypothyroidism and Metabolic syndrome were calculated in the Endocrine OPD of BIRDEM during November 2010 to May 2011.Age of the PCOS population was 23.02±7.04 year, central obesity in 81.4%, abnormal glucose tolerance in 47.1%, dyslipidemia in 45.7%, hypertension in 24.3%, hirsutism in 88.6%, acanthosis nigricans in 50%, polycystic ovaries by ultrasound (87%) cases. One third of the PCOS cases i.e.; 33% were without hyperprolactinemia or hypothyroidism or Metabolic Syndrome. And the rest 47 cases had one, two or all the 3 with them. The distribution was PCOS with hyperprolactinemia 18.6%, PCOS with hypothyroidism 11.4%, PCOS with Metabolic Syndrome 15.3%, PCOS with hyperprolactinemia with MS 8.6%, PCOS with hypothyrodism with MS 5.6%, PCOS with hypothyrodism with hyperprolactinemia 4.3% and rest 4.3% had all the 4 in combination. Blood glucose levels during OGTT and TSH levels of the group without Hypothyrid, hyperprolactinoma or Metabolic Syndrome were significantly lower (p≤0.008). Significant proportion of Bangladeshi women with PCOS has hypothyroidsm with or without high prolactin and also have higher incidence of metabolic syndrome. So, all PCOS patients should also be screened for hypothyroidsm and hyperprolactinemia.

In this study we evaluated the analgesic efficacy of bilateral superficial cervical plexus block after thyroid surgery. Sixty patients were assigned to two groups. General anesthesia was induced with 2mg/kg propofol, 0.1mg/kg vecuronium and 1.5µg fentanyl IV for both group. After endotracheal intubation, bilateral superficial cervical plexus block with 0.25% bupivacaine 15ml in each side was performed in Group I. In Group II (control) no regional block was administered. Intravenous on demand analgesic was used to evaluate postoperative analgesic requirement. Neither visual analog scale scores nor intravenous analgesics doses were different between the groups. The first analgesic requirement time in Group I was significantly longer than for the control group. The incidence of nausea and vomiting was significantly lower in Group I than Group II. We concluded that bilateral superficial cervical plexus block with 0.25% bupivacaine did not decrease analgesic requirement after thyroid surgery.

Donation after cardiac death (DCD) has proven effective at increasing the availability of organs for transplantation.We performed a retrospective examination of Massachusetts General Hospital (MGH) records of all 201 donors from 1/1/98 to the 11/2008, including 54 DCD, 115 DBD and 32 DCD candidates that did not progress to donation (DCD-dnp). Comparing three time periods, era 1 (01/98-12/02), era 2 (01/03-12/05) and era 3 (01/06-11/08), DCD's comprised 14.8,48.4% and 60% of donors, respectively (p = 0.002). A significant increase in the incidence of cardiovascular/cerebrovascular as cause of death was evident in era 3 versus eras 1 and 2; 74% versus 57.1% (p<0.001),as was a corresponding decrease in the incidence of traumatic death. Interestingly, we noted an increase in utilization of aggressive neurological management over time, especially in the DCD group.We detected significant changes in the make-up of the donor pool over the past decade. That the changes in diagnosis over time did not differ between DCD and DBD groups suggests this difference is not responsible for the increase in DCD rates. Instead, we suggest that changes in clinical practice, especially in management of patients with severe brain injury may account for the increased proportion of DCD.
