We hypothesised that the promotion of blister packs of zinc may be carried out by health personnel in health care facilities to the mothers of children suffering from diarrhea. We predicted that good acceptability and good compliance to zinc treatment in rural Bangladesh would be over 75% and at least 60%, respectively. Between January and December 2011, six hundred and thirty five children aged 6 - 59 months who presented with acute diarrhea received a 10-day zinc regimen. Determination of acceptability and compliance of a dispersible zinc tablet in children 6 - 59 months old was main point of the study. In-home follow-ups started within 2 - 3 weeks after the regimen began. Seventy seven percent of the mothers/caretakers perceived that the taste of the zinc tablets was the same or better than that of other medicines given to their children and expressed willingness to use zinc in the future (good acceptability). Sixty-two percent of the children completed full 10-day course of zinc treatment by taking one tablet a day that had been completely dissolved in a small amount of water (good compliance). There was 63% excess risk for poor compliance to zinc if father stays at home with the family [OR = 1.63 (95%CI;1.09, 2.46) p = 0.019]. Despite vomiting, 33% children continued to receive zinc tablet [OR = 0.67 (95%CI;(0.47, 0.97, 0.032)] after adjusting for co-variates. Both acceptability and compliance to dispersible zinc tablets in childhood diarrheal illnesses are still not at the expected level in rural Bangladesh.

The study aimed to determine the epidemiological, clinical characteristics, and etiology of adults aged ≥20 years presented with prolonged acute diarrhea (≥7 days). A total of 18,210 adults aged ≥20 years were enrolled in the Diarrheal Disease Surveillance System of icddr,b between 1993-2012 and included into the analysis. Of these, 17,631 (97%) had duration of diarrhea ≤6 days, 418 (2%) diarrhea presented with a duration of 7 - 13 days and rest 161 (1%) had history of diarrhea ≥14 days. A higher proportion of adult individuals who had duration of diarrhea ≥14 days (70% vs. 56%;p male. At least 73% of all patients used oral rehydration solution;but proportion was lower among prolonged acute diarrhea groups. Use of antimicrobials was higher among those with duration 7 - 13 days (81%) and ≥14 days (81%). Diarrhea lasting ≥14 days, 47% were suffering from chronic energy deficiency and 30% had history of smoking. Individuals with diarrhea ≥7 days less frequently presented with vomiting, watery stool, frequency of stool >10 times/24 hours, drowsy or lethargy, fast breathing, some or severe dehydration, received intravenous saline for initial corrections of dehydration and stayed for longer duration in hospital (≥24 hours) but more often presented with abdominal pain. Stool microscopic examination showed less frequent presence of red blood cells (36% vs. 44%;p = 0.043) and fecal leucocytes (50% vs. 59%;p = 0.029) among individuals with diarrhea ≥14 days compared to those with ≤6 days. None was infected with Vibrio cholerae (≥14 days) (3% for 7 - 13 days);however, isolation rate of Aeromonas was higher among adults with duration for ≥14 days (11%). Only 15% with ≥14 days were positive for Shigella contrary to 19% (7 - 13 days) and 56% (≤6 days). Differences in sociodemographic, clinical presentation and etiology varied with duration of diarrhea among adults.

As per strict criteria of das Gupta et al, primary splenic lymphoma is very rare. Herein, we are reporting an unusual case of primary large cell splenic lymphoma of B lineage in a middle aged female presenting with massive splenomegaly(3.8 kg) and hypersplenism. After performing therapeutic splenectomy for hypersplenism, a precise diagnosis of diffuse large B cell lymphoma was made on histopathology and confirmed by immunohistochemistry. The patient responded well to standard(Cyclophosphamide, Hydroxydaunorubicin, Oncovin(vincristine), Prednisone or prednisolone) regimen last year and is now in full remission. The splenectomy thereby has prevented the potential grave complications related to hypersplenism and splenic rupture. Our aim behind highlighting the topic is to specify that emergency splenectomy followed by anticoagulation therapy is an effective plan of management to prevent untoward complications related to disease and treatment.

There is scarcity of evidence-based information about socio-demographic as well as ailment factors associated with foster children in Bangladesh. Thus the aim of the present study was to determine the socio-economic, health and nutritional status of young foster children in urban Dhaka. A total of 208 (1%;n = 208/28,948) under-5 foster children were enrolled in the Diarrheal Disease Surveillance System of icddr,b between 1993-2012. Randomly selected under-5 children (n = 624) with a ratio of 1:3 were extracted and constituted as comparison group. Forty-three percent (n = 90) foster children were male. Lack of formal schooling of mother was higher among foster children compared to non-foster children (52% vs. 35%;p < 0.001). Higher proportion of foster children suffered from some or severe dehy-dration (60% vs. 47%;p = 0.001) and often received intravenous saline (12% vs. 5%;p = 0.002) in comparison to non-foster children. Significantly lower proportion of foster children had rotavirus diarrhea (26% vs. 43%;p < 0.001). In multivariate analysis, foster children were 2 times (95% CI: 1.31-4.32) more likely to be stunted and 194 times (95% CI: 82.25-457.76) more likely to be non-breastfed. Infants aged 6-11 months were 8 times (95% CI: 3.70-15.50) more likely to be foster compared to older children and probability of fostering was 7 times (95% CI: 3.96-13.33) higher among mothers with a median age of 25 years. The findings of our study clearly demonstrate the existing health and nutritional problems of foster children. Therefore, appropriate health and nutrition interventions are critical for foster children in Bangladesh.

Background: Vitamin D is not only important for bone health but can also affect the development of several non-bone diseases. These findings have increased the need for determining vitamin D status in a convenient and cost-effective way. In order to determine the better method for detecting vitamin D status, we have estimated blood vitamin D in three methods such as high-pressure liquid chromatography, chemiluminescent immunoassays and enzyme immunoassays. Method: Two hundred and sixteen subjects irrespective of age and sex were studied for blood vitamin D in all the three methods over a period of 2 years. Result: The statistical analysis showed that values of vitamin D obtained by chemiluminescent immunoassays (r = 0.978,

Agricultural Sciences 2012年第2期3卷 208-213页

Genetic improvement of crop plants is brought about by manipulating the genetic makeup through systematic breeding techniques or by employing modern biotechnological tools. Application of systematic breeding technique to a large extent is decided by the knowledge on the genetic control of the traits. Keeping this in view, nine mulberry genotypes were evaluated for different growth and yield attributing traits viz., number of tillers (NT), plant height (PH), total shoot length (TSL), nodal distance (ND), leaf fall % (LF), number of leaves/plant (NLP), weight of 100 fresh leaves (WFL), weight of 100 dry leaves (WDL), single leaf area (LA), leaf area index (LAI), aboveground biomass (AGB), leaf harvest index (LHI) and leaf yield (LY) and estimated the magnitude of genotypic and phenotypic variation, heritability, genetic advance and correlation coefficients. The broad sense heritability for these traits ranged from 63.942 (WFL) to 13.261 (PH). High heritability coupled with high genetic advance was recorded for the characters WFL, LF, LA, WDL and LY suggesting the higher genetic control over these traits. Leaf yield showed significantly positive phenotypic and genotypic correlations with all other growth traits except PH and LF. Leaf fall had significant negative correlations with all the highly heritable yield attributes viz., ND (-0.379), WDL (-0.225), LA (-0.346), LAI (-0.233) at 1% level and AGB (-0.148), LHI (-0.122) and LY (-0.146) at 5% level. Likewise, it showed positive correlations with TSL (0.558), NLP (0.264) and PH (0.221). Since mulberry is mainly cultivated for leaf yield, genotypes having higher WFL, LA, WDL and LY and less LF must be given importance during parent selection to evolve high yielding varieties with less leaf fall across different seasons in mulberry.
