Abstract
Renal dysfunction is a well-known complication following heart transplantation. We examined an early decline in kidney function as a predictor of progression to end-stage renal disease and mortality in heart transplant recipients. We performed a retrospective cohort study of 233 patients who received a heart transplant between July 1985 and July 2004, and who survived >1 month. The decline in estimated creatinine clearance (CrCl) was used to predict the outcomes of need for chronic dialysis or mortality >1-year posttransplant. The earliest time to chronic dialysis was 484 days. A 30% decline in CrCl between 1 month and 12 months predicted the need for chronic dialysis (p = 0.01), all-cause mortality (p < 0.0001) and time to first CrCl </=30 mL/min at >1-year posttransplant (p = 0.02). A 30% decline in CrCl between 1 month and 3 months also independently predicted the need for chronic dialysis (p = 0.04) and time to first CrCl </= 30 mL/min at >1-year posttransplant (p = 0.01). In conclusion, an early drop in CrCl within the first year is a strong predictor of chronic dialysis and death >1-year postheart transplantation. Future studies should focus on kidney function preservation in those identified at high risk for progression to end-stage kidney disease and mortality.

Abstract
The aim of the present study was to formulate and evaluate pharmaceutically equivalent injectable aqueous suspension for parenteral depot of methyl prednisolone acetate. Various aqueous suspensions were prepared by rapid stirring and colloid milling method. The prepared aqueous suspensions were subjected to particle size determination, sedimentation study, in vitro release studies (pH dependent dissolution study), and stability studies. The optimized formulation consisted of 4% w/w of methyl prednisolone acetate, 2.91% w/w of PEG-3350, 0.19% w/v of injection grade Tween-80, 0.68% w/w of monobasic sodium phosphate, 0.15% w/w of di-basic sodium phosphate, 0.91% w/v of benzyl alcohol, 0.32% w/w sodium meta bisulphate. The f(2) value was calculated for innovator (DepoMedrol( ((R)) ), Batch No. MPH-0254) and optimized formulation at pH 6.8 and pH 7.4 phosphate buffers. The f(2) values of 62.94 and 54.37 were obtained at pH 6.8 and pH 7.4 phosphate buffers respectively. The particle size ranged 23-27 mum at D value of 0.9 for both test and innovator product.

Abstract
Organochlorine pesticides (OCPs) are an important potential component of chemical pollutants used extensively for agriculture and sanitation purposes in India as these are comparatively cheap and effective. These persistent organic compounds such as HCH isomers, DDT and its metabolites are the predominant chemical contaminants found along the Indian coast and thus constitute both alluring and grave areas of scientific research. Our objective in the paper is to provide a comprehensive account of the distribution of organochlorine pesticides in biotic and abiotic compartments of the Indian coastal environment, make some comments on their environmental sources, their movement through the food chain and possible ecotoxicological risk of health in biota including humans. The prevalent HCH, DDT and HCB concentrations differ markedly in eastern and western coast of India reflecting differing agricultural and other usage and their ultimate input into the coastal environment by several rivers and the bioturbation activities of macrozoobenthos (bivalve mollusks, polychaetous annelids, etc.). In several cases, the DDT levels exceeded the effects range-low (ER-L) and could thus cause acute biological impairments, in comparison with the sediment quality guidelines. Contributions of DDT metabolites (DDT, DDD and DDE residues) vary in different Indian coastal regions predominated by pp'-DDT and pp'-DDD. Measured concentrations of HCHs were lower than DDTs that might be due to higher water solubility, vapor pressure and biodegradability of the latter. HCH and DDT residues in fish in India were lower than those in the temperate countries indicating a lower accumulation in tropical fish, which might be related to rapid volatilization of this insecticide in the tropical environment. The concentrations of other chlorinated pesticides (aldrin, dieldrin, eldrin, methoxychlor, endosulfan sulphate) were lower and not generally of great concern.

Abstract
14139 Background: Carcinoma breast is the second most common malignancy in Bangladeshi women. Though HER-2 over expression has profound effect on prognosis of breast cancer, no published data is available about this among Bangladeshi patients. Our aim in this study was to see HER-2 status in Bangladeshi patients, and their relation with other prognostic parameters. Implication of this molecular marker in management of breast cancer in poor country like ours remains controversial, keeping in mind the exorbitantly high cost of Trastuzumab. Methods: This prospective study was conducted in the department of Oncology at Bangladesh Medical College Hospital, National Institute of Cancer Research and Hospital and Ahsania Mission Cancer Hospital Bangladesh, from January 2003 to December 2006. Total 250 women with breast carcinoma were enrolled; biopsy specimens were tested by immunohistochemistry to detect HER-2 status. For recommending treatment with Trastuzumab, patients with 3+ immunohistochemistry results were considered HER-2 positive. Fluorescent In Situ Hybridization (FISH) testing facility was not available. These findings were correlated with age, ER/PR and nodal status. The practical application of marker in terms of use of Trastuzumab was analyzed. Results: Age of patients ranged from 19.75 years to 72 years, mean age was 49.75 years. HER-2 was over expressed in 38.4 % (96) cases and their mean age was 42.92 years compared to 47.61 years in HER-2 negative cases. HER-2 positive cases tended to have higher rates of lymph node metastases (44 out of 96) compared to HER-2 negative (46 out of 154) cases (45.8 % vs 29.87 %). ER/PR was positive in 64 % cases. HER-2 over expression was inversely related to ER / PR expression. Of the HER-2 positive cases, 11.45 % (11 out of 96) afforded treatment with Trastuzumab. Conclusions: HER-2 is over expressed in almost 38 % of breast carcinoma patients in Bangladesh. This expression is associated with relatively young age, lymph node metastasis and lack of ER / PR expression. Only 11.45 % of patients with HER-2 over expression afforded Trastuzumab though 38 % of cases over expressed HER-2. No significant financial relationships to disclose.

Abstract
End-stage renal disease is a significant complication of heart transplantation (HTx), but our understanding of dialysis outcomes in HTx recipients remains limited. We performed a retrospective analysis looking at dialysis mortality in HTx recipients as compared to a matched dialysis cohort. We also examined outcomes with respect to kidney transplantation (KTx) in these cohorts. 2709 incident HTx recipients were captured from the Canadian Organ Replacement Register between 1981 and 2002. The incidence of dialysis after HTx was 3.9% (n = 105) and carried a greater crude mortality compared to HTx recipients not requiring dialysis (56.2% vs. 35.9%, p < 0.001). Compared to the matched dialysis cohort, survival of HTx patients on dialysis was also significantly worse (19% vs. 40%, p = 0.003). In those receiving a KTx, survival did not differ between the two cohorts; however, in those that did not receive a KTx the survival was significantly lower in the dialysis post-HTx group compared to the matched dialysis cohort (15.7% vs. 35.2%, p < 0.025). Our analysis suggests mortality on dialysis following HTx is greater than would be expected from a similar dialysis population, and KTx may abrogate some of this increased risk. Attention should be placed on preventing chronic kidney disease progression following HTx.

Abstract
The course of pregnancy and its outcome was studied in renal allograft recipients. Between November 1985 and November 2005, a total of 1481 renal transplants were carried out at the Sindh Institute of Urology and Transplantation (SIUT); among them were 348 females, with 73 potential females for pregnancy. All patients received cyclosporine and prednisolone, with 82% also receiving azathioprine and 4 patients mycophenolate mofetil as a third immunosuppressant drug. We evaluated incidence of hypertension, diabetes, pre-eclampsia, urinary tract infection (UTI), rejection during pregnancy and during 3 months' postdelivery as well as outcomes of pregnancy. Among 73 potential candidates, 31 had 47 pregnancies, after an average of 31 months (8-86 months). Of 31 subjects, 21 subjects were hypertensive on one or two drugs prior to conception. A rise in blood pressure during pregnancy was noticed in 7 patients. Albuminuria from trace to 3+ appeared in 13 patients and glycosuria in one other. Blood sugar levels remained within normal range in all subjects. UTIs occurred during pregnancy in 7 patients. Among 47 pregnancies, 9 had abortions (7 spontaneous, 2 therapeutic) and 6 had preterm deliveries. The others were full-term deliveries: 12 via a lower segment caesarean section and 20 were normal vaginal deliveries. Average birth weight was 4.8 lbs. At an average follow-up of 38 months the serum creatinine values ranged from 0.94 to 2.3 mg %. One patient developed acute irreversible graft dysfunction soon after delivery. Our study demonstrated that pregnancy did not reduce renal graft survival, but newborns are at greater risk of premature birth and low birth weight.

Abstract
Incomplete intertrochanteric fractures do not extend across to the medial femoral cortex and are stable, without rotational deformity or shortening of the lower limb. The aim of our study was to establish whether they can be successfully managed conservatively. A total of 68 patients over a five-year period presented with a suspected fracture of the femoral neck and underwent an MRI scan for further assessment. From these, we retrospectively reviewed eight patients with normal plain radiographs but with an incomplete, intertrochanteric fracture on MRI scan. Five were managed conservatively and three operatively. The mean length of hospital stay was 16 days for the conservatively-treated group and 15 days for those who underwent surgery; this was not statistically significant (p > 0.5) and all patients were mobilised on discharge. Although five patients were readmitted at a mean of 3.2 years after discharge, none had progressed to a complete fracture. We believe that patients with incomplete intertrochanteric fractures should be considered for conservative treatment.

Abstract
There are several prognostic models for Hodgkin's disease (HD) patients, but none evaluating patient characteristics at time of blood and marrow transplantation (BMT). We developed a prognostic model for event-free survival (EFS) post-BMT based on HD patient characteristics measured at the time of autologous (auto) or allogeneic (allo) BMT. Between 1/1991 and 12/2001, 64 relapsed or refractory HD patients received an auto (n=46) or allo (n=18) BMT. A multivariate prognostic model was developed measuring time to relapse, progression or death. Median follow-up was 51.7 months; median EFS for auto and allo BMT was 36 and 3 months, respectively (P=0.001). Significant multivariate predictors of shorter EFS were chemotherapy-resistant disease, KPS <90 and > or =3 chemotherapy regimens pre-BMT. Patients with two to three adverse factors had significantly shorter EFS at 2 years (58 vs 11% in auto; 38 vs 0% in allo BMT patients). Despite a selection bias favoring auto BMT, the model was valid in both auto and allo BMT groups. We were able to differentiate patients at high vs low risk for adverse outcomes post-BMT. This prognostic model may prove useful in predicting patient outcomes and identifying high-risk patients for novel treatment strategies. Validation of this model in a larger cohort of patients is warranted.

Abstract
Pneumatic balloon dilatation is the treatment of choice for esophageal achalasia. Rigiflex (Microvasive, Watertown, MA) polyethylene balloon dilators have been used with varying success and complications. The aim of this study was to evaluate the efficacy of graded balloon dilatation, to achieve symptomatic improvement in patients with achalasia. From January 1987 until the end of December 2003, 300 patients were evaluated and treated for achalasia, with 30 mm balloons. Patients who did not achieve satisfactory symptomatic responses during follow up underwent repeat dilatation with 35-mm balloons. They were studied at the onset then at 1 and 6 month intervals and then yearly for postdilatation symptom evaluation for dysphagia, regurgitation, night cough and heartburn. Baseline and 5-min postdilatation barium swallow studies were obtained to compare barium height and width for efficacy of dilatation and to evaluate for complications. No patients developed cancer of the esophagus in 16 years follow up. Barium height, width, composite symptom score and weight improved significantly during follow up. Two patients, who needed repeat dilatation with 35-mm balloons, developed esophageal perforation; one was successfully managed with intensive medical care management, whereas the other patient died despite surgical intervention. The authors conclude that pneumatic balloon (Rigiflex) dilatation for achalasia of the esophagus is a successful first option, when applied in an incremental balloon size to achieve desired results in symptomatic relief.

Abstract
Purpose To evaluate the safety and efficacy of fludarabine plus rituximab in treatment-naïve or relapsed patients with low-grade and/or follicular non-Hodgkin's lymphoma. Patients and Methods This was an open-label, single-arm, single-center phase II study enrolling 40 patients. During the first week of the study, patients received two infusions of rituximab 375 mg/m2 administered 4 days apart. Seventy-two hours after the second infusion of rituximab, patients received the first of six cycles of fludarabine chemotherapy (25 mg/m2/d for 5 days on a 28-day cycle). Single infusions of rituximab were administered 72 hours before the second, fourth, and sixth cycles of fludarabine, and two infusions of rituximab were given 4 weeks after the last cycle of fludarabine. Treatment duration was 26 weeks. Results An overall response rate of 90% (80% complete response rate) was achieved in the intent-to-treat population. Similar response rates were seen in treatment-naïve and previously treated patients. The median duration of response has not been reached at 40+ months. The median follow-up time in this study is 44 months (range, 15 to 66 months). In patients positive for the 14;18 translocation in blood and/or marrow at enrollment, molecular remission was achieved in 88% of cases, with patients remaining negative for up to 4 years to date. Hematologic toxicity was manageable, and except for a 15% incidence of herpes simplex/zoster infections, infectious complications were rare. Nonhematologic toxicities were minimal. Conclusion Rituximab plus fludarabine was well tolerated and associated with an excellent complete response rate, including molecular remissions, in patients with low-grade or follicular lymphoma.

Abstract
The present paper assesses the chemopreventive potential of retinoic acid on benzoyl peroxide (BPO)-induced cutaneous tumor promotion response and oxidative stress in murine skin. In this study, we have shown the activities of cutaneous antioxidant enzymes and phase II metabolizing enzymes and the glutathione content were decreased while epidermal ornithine decarboxylase (ODC) activity and DNA synthesis were induced in benzoyl peroxide treated animals. Topical application of retinoic acid resulted in significant inhibition of benzoyl peroxide-induced epidermal ornithine decarboxylase activity and DNA synthesis. Application of retinoic acid at three different doses prior to the application of benzoyl peroxide recovered the depleted level of glutathione, inhibited activities of antioxidant and phase II metabolizing enzymes, thus resulting in significant inhibition of oxidative stress in dose dependent manner. Enhanced susceptibility of cutaneous microsomal lipid peroxidation and xanthine oxidase activity were significantly reduced (P > 0.05). The antimutagenic effect of retinoic acid was tested against benzoyl peroxide mediated mutagenicity in Salmonella typhimurium strain TA-98 and TA-100 using 3-methyl cholanthrene-induced murine skin (S9 fraction) as the metabolic activation system. Indeed, with the addition of various concentrations of retinoic acid there was significant reduction in the number of revertants per plate in concentration dependent manner. In summary, our data indicates that retinoic acid may exhibit cancer chemopreventive activity in skin tumorigenesis model.

Abstract
A total of 1432 hilsa shad, Tenualosa ilisha (=Hilsa ilisha) from 11 fresh water, brackish water and marine localities in Bangladesh yielded 13 adult Goezia bangladeshi n. sp., all specimens being found in the intestine of a single fish host caught in the lower Ganges. A total of 2372 Goezia juveniles were recovered from 490 infected fish (prevalence 34.2%). This is the first Goezia species recorded from Bangladesh, and it differs from other valid species by the number of caudal papillae (pre 7-9, para 3, post 6); encircled by tiny spines, the position of double papillae, the arrangement of body spines, and the length ratio of the intestinal caecum and the ventricular appendix (1: 3.33-4.72). Juveniles were free in the gut, embedded in the gut wall and encapsulated in mesenteries. Tenualosa ilisha serves as the definitive host, but the predominance of juveniles may indicate that piscivorous hosts may also serve as such. A list of the nominal Goezia species with important characters is provided.
