    ABSTRACT: The interventional type of study to assess the efficacy of Pimecrolimus cream in the treatment of patient of localized discoid lupus erythematosus (DLE) was carried out for a period of July 2008 to June 2009. It was observed that before treatment, erythema was severe in 43.2% cases, moderate in 51.4% cases and mild type erythema was present in 5.4% cases. The post- treatment revealed, 29.7% severe type erythema, none evidenced moderate type erythema, only 43.2% had mild type and 27% cases no erythema at all. Before treatment, infiltration was severe in 27% cases, moderate in 54.1% cases and only 18.9% had mild type infiltration. But after treatment, 10.8% had severe type infiltration, 18.9% had moderate, 51.4% had mild and 18.9% had no infiltration at all. Similar response to treatment was noticed with squamation which exhibited a drop from 37.8% to 18.9% in severe cases and from 62.2% to 10.8% in moderate cases. There was a 45.9% mild case and 24.3% had no squamation. The scoring result of photosensitivity, itching, disfigurement evidenced analogously score reduction of 2.0, 3.05 and 3.12 respectively. In conclusion, it was interpreted that score of patients of DLE, before treatment was 6.83 ± 1.30 and after treatment was 3.83 ± 1.18. Unpaired 't' test was found statistically significant (p<0.05) between before and after treatment by drug. Improvement was shown in 26(70.27%) cases and 11(29.73%) cases shown no improvement at all. Marked improvement observed on the 2nd follow up visit at the end of 12 weeks. Response was good in 23(88.46%) cases, fair 2(7.69%) and poor 1(3.85%) cases. The study suggests that pimecrolimus 1% cream has significant efficacy profile for treatment option of cutaneous lupus erythematosus.

    ABSTRACT: A sustainable semi-intensive pond aquaculture technology including major carp species as ‘cash-crop’ and small indigenous fish species (SIS) as food for the farmers' families is being optimized in Bangladesh. This is done through manipulations of the fish species combinations stocked, considering the ecological effects produced by bottom feeders on the pond bottom and filter feeders in the water column. The present paper presents results of experiments performed simultaneously in 64 farmers' fish ponds, located in 4 distant agro-ecological regions of Bangladesh. In each region each experiment involved 4 treatments, 4 replicates per treatment. The control polyculture was the traditional stocking of 33 rohu (Labeo rohita), 33 catla (Catla catla), and 34 common carp (Cyprinus carpio) per 100m2, with the addition of 250 SIS and 3 silver carp (Hypophthalmichthys molitrix) per 100m2. In previous experiments this silver carp addition was found to have no effects on the other fish and on the environment, compared to the traditional stocking without silver carp. Interferences on the water column (Water treatment) were achieved changing the density of the herbivorous fish (reducing catla density to 24/100m2 and increasing silver carp to 12/100m2), and on the bottom (Bottom treatment) doing so on the benthophagous fish (replacing 10/100m2 common carp by mrigal). Both interferences were simultaneously carried out in the Water and Bottom treatment. Harvesting weight and biomass, growth rate, survival and yield of each species and total yield, food conversion ratio and income obtained in the different treatments and regions are presented and their interactions through the food web are discussed. Performing the same experiment in four distant regions of the country allowed observing if the effects of the Water column and/or Bottom interventions differ among regions, and accelerating the dissemination of the “cash-SIS” technology throughout the country. The manipulations performed did not affect the small fish mola, which reproduced and yielded equally well in all the polycultures. This allowed a continuous mola supply for consumption by the farmers' families throughout the culture season, and opened the option to consume or sell the larger amounts of mola gathered at final harvest. Manipulation of species composition proved to be a useful tool to affect the pond ecosystem towards improving fish yield and corresponding income. Just by substituting almost a third of the catla by silver carp increased total yield by 16%. When also almost a third of the common carp was substituted by mrigal, total yield increased a further 3%. In both cases selling the whole production increased income by 27%, which gives the farmer the option to keep part of the fish for family consumption.

    ABSTRACT: Atopic dermatitis (AD) is a common pruritic, eczematous skin disorder that runs a chronic and relapsing course. Major and minor criteria exist as guideline for arriving at a diagnosis of AD. Minor features vary with ethnicity and genetic background and can be used to aid diagnosis. A descriptive study was conducted including 210 patients of 1-12 years age who had concurrent or past history of AD according to criteria of Hanifin and Rajka. This study was conducted in the department of Dermatology of three different Hospitals of Bangladesh. Out of 33 sub-criteria of Hanifin and Rajka, 20 of which were examined encompassed tendency towards cutaneous infection, environmental factor, high IgE level, intolerance of wool, xerosis, infra-orbital fold, ichthyosis, early age of onset, itch on sweating, palmer hyperlinearity, food hypersensitivity, keratosis pilaris, pityriasis alba, facial erythema, cheilitis, hand eczema, foot eczema, intolerance of lipid solvent, scalp scaling and infra-auricular fissure. Out of 20 examined minor criteria, most common was cutaneous infection in 168(80.0%) patients followed by coursed influenced by environmental factor in 140(66.7%), high IgE level in 126(60.0%), intolerance of wool in 105(50.0%), xerosis in 92(43.8%), infra-orbital fold in 83(39.5%), ichthyosis in 72(34.3%), early age of onset in 65(31.0%), itch on sweating in 56(26.7%), palmary hyperlinearity in 52(24.8%), food hypersensitivity in 40(19.0%), keratosis pilaris in 31(14.8%), pityriasis alba in 30(14.3%), facial erythema in 25(1.9%), cheilitis in 22(10.5%), hand eczema in 19(9.0%), foot eczema in 16(7.6%), intolerance of lipid solvent in 14(6.7% ), scalp scaling in 11(5.2%) and infra-auricular fissure in 10(4.8%). These features were present singly or in combination. The result evidenced that minor criteria are many a times important for the diagnosis where major criteria are uncertain.

    ABSTRACT: An on-station trial was conducted to investigate the effects of three C/N ratios (10/1, 15/1 and 20/1) along with substrate presence or absence on natural food communities in freshwater prawn culture ponds. An experiment was carried out in 40 m2 ponds stocked with a stocking density of 2 prawn juveniles (5.023 ± 0.02 g) m―2. A locally formulated and prepared feed containing 30% crude protein with C/N ratio 10 was applied to all ponds. In order to raise the C/N ratio of the feed input to 15 and 20, tapioca starch was applied separately as a source of carbohydrate in addition to the artificial feed. Under substrate treatments, bamboo side shoots were posted vertically in pond bottoms resulting in 100% additional surface area as periphyton substrates. The treatments with different C/N ratios are referred to as "CN10", "CN15" and "CN20". Increasing the C/N ratio from 10 to 20 significantly increased the biovolume of phytoplankton, crustaceans and rotifers in the water column by 15%, 6% and 11%, respectively. The biovolume of periphyton was 50% higher in treatment CN20 compared to treatment CN10. Increasing the C/N ratio from 10 to 20 raised the biovolume of total heterotrophic bacteria (THB) in the water column (70%), sediment (36%) and periphyton (40%). The chironomids biovolume was also significantly higher (28%) in treatment CN20 compared to treatment CN10. The addition of substrates decreased the biovolume of water column plankton by 14% but the combined biovolume (plankton+ periphyton) was almost double in substrate-added ponds. The biovolume of plankton, periphyton and THB increased significantly with culture time duration whereas the biovolume of benthic macroinvertebrates decreased significantly with culture time indicating that freshwater prawn grazed on them. A significant interaction between C/N ratios and substrate presence or absence was only observed for plankton biovolume in the water column. This study demonstrated that plankton, periphyton and microbial biofloc communities were under-utilized by the freshwater prawn in treatment CN20. This leaves room for increasing the stocking density of prawn and/or inclusion of periphyton grazing fish species to improve nutrient utilization efficiency and overall sustainability.

    ABSTRACT: This descriptive type of study was carried out to determine the various factors of attempted suicide in a selected area at Patnitala and Dhamuirhat upazilla health complex of Naogaon district. All reported alive cases of attempted suicide (self poisoning, hanging, self burning or immolation, drowning etc) during the period from March to June 2003 were interviewed purposely. Data were collected by face to face interview and also from hospital records. Of the interviewed cases, the mean age was 21.4 years. Household workers, day labours, students and agricultural workers (42.6%, 23.9%, 15.5% and 11.3% respectively) were the major victims and nearly 60% had nuclear family. The highest number (77.5%) used organophosphorus compound. Highest number (25.4%) mentioned that husband mainly provoked for suicidal attempt, followed by mother and father. It was evident that 71.8% of suicidal attempt was due to their emotional stress, followed by family violence, disturbed family, social deprivation, stressful events and health problems (50.7%, 49.3%, 36.6%, 25.4%, and 8.5% respectively). It was evident that attempted suicide is proportionately higher among adolescents of unmarried, with early age at marriage, with higher income and with nuclear family compared with adult. Emotional stress, disturbed family, social deprivation, health related problems are appeared to be important reasons for attempted suicide among adolescents whereas family violence in adults.

    ABSTRACT: Lichen planus is one of the common inflammatory disorders of skin, mucous membrane, nail and hair characterized by violaceous, polish, pruritic, polygonal, flat-topped papules usually distributed bilaterally symmetrically over the extremities. Our objectives in this study were to explore the prevalence of lichen planus in large area of Dhaka in Bangladesh and to establish the clinical characteristics of lichen planus. This descriptive type of cross sectional study was carried out from September 2006 to August 2008 in the Department of Dermatology and Venereology of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka Medical College Hospital (DMCH) and Combined Military Hospital (CMH) in Dhaka. Patients suffering from lichen planus were selected as study population. By face to face interview and clinical observations, data were collected from sample. A total 120 patients of lichen planus were selected, on the basis of age, 30(25%) were 10-30 years of age, 75(62.56%) were 30-50 years and 16(13.33%) were over 50 years of age. The mean age of the patient was 40+/-4 years. Out of 120 patients, 80(66.66%) were male and 60(33.33%) were female and eight patients (6.67%) had positive family history among highest age group (30 to 50 years). In case of duration of disease, highest percentage (68%) of cases was 15 days to 6 months and considering clinical sign, koebnerization was present 45(37.5%) cases and Wickhams striae 22(18.33%) cases. Regarding site of onset of lesion, lesions were highest 100(83.33%) in upper limbs, next lower limbs, trunk, oral mucosa etc. The distribution of clinical pattern of lichen planus showing classic pattern (68.33%) was the most common type, followed by hypertrophic, actinic, ashy dermatoses, lichen plano-pilaris, erosive or ulcerative etc. This clinico-epidemiological study of lichen planus attending in the different hospital in Dhaka, Bangladesh has shown that lichen planus is usually associated with 30 to 50 years of age group, with higher male prevalence than female, 15 days to 6 months are mainly duration of disease, koebnerization and Wickhams striae are common clinical signs, upper limbs is mainly the site of onset of lesion, and classic pattern is the most common clinical type in lichen planus.

    ABSTRACT: The present research investigated the effect of carbohydrate (CH) source for maintaining a high C:N ratio, and tilapia driven bioturbation on pond ecology, production and economical performances in C/N controlled periphyton-based (C/N-CP) freshwater prawn ponds. Two carbohydrate sources (high-cost tapioca starch and low-cost maize flour) were compared in 40 m2 ponds stocked with 80 freshwater prawn (Macrobrachium rosenbergii) juveniles (individual weight 0.81 ± 0.03 g) and 20 finfish fingerlings (Nile tilapia, Oreochromis niloticus and Indian major carp rohu, Labeo rohita) in three different combinations: 100% tilapia, 50% tilapia + 50% rohu, and 100% rohu (individual weight 27.7 ± 0.6 g). The CH sources for increasing C:N ratio from 10 (as in feed) to 20 had no significant effect (P > 0.05) on water quality parameters, abundance of natural food (plankton, periphyton and benthos) and production of prawn and finfish. However, different fish combination had significant effects on pond ecology. The highest PO4–P (P < 0.001) and the lowest chlo-a (P < 0.01) concentrations in water were observed in ponds with 100% tilapia as compared to ponds stocked with 100% rohu. The abundance of phytoplankton, periphyton biomass (dry matter, ash, ash free dry matter and chlo-a) and benthos was significantly higher (P < 0.05) in 100% rohu ponds than in 100% tilapia ponds indicating the more efficient utilization of natural food items by tilapia than by rohu. The freshwater prawn production was not affected (P > 0.05) by the different stocking combinations of finfish. The net yield and survival of finfish were significantly higher in 100% tilapia ponds and lower in 100% rohu ponds resulting in 58% higher combined net yield (both prawn and finfish) in the former treatment during a 120-d culture period. This treatment gave the best economic return in terms of benefit–cost ratio while maize flour was used as CH source. In conclusion, maize flour can be used as an alternative cheap on-farm CH source for maintaining a high C:N ratio and tilapia driven re-suspension in C/N-CP system improves culture environment, natural food utilization, production and economic return, further enhancing economic sustainability of C/N-CP freshwater prawn farming system.

    ABSTRACT: Tinea (pityriasis) versicolor is a superficial fungal infection and one of the most commonly found pigmentary disorders of skin caused by the yeast Malassezia. Multiple topical as well as systemic therapies are available for treatment. Systemic therapies are used for extensive disease, frequent relapse or where topical agents have failed. The aim that translates the rationale of the study was to compare the efficacy, safety, tolerability and cost effectiveness of single dose 400mg versus 7 day 200 mg daily dose of itraconazole in the treatment of tinea versicolor. A clinical study was done to compare the efficacy of single dose (400 mg) of itraconazole and 7 day 200 mg daily dose of itraconazole in the treatment of extensive tinea versicolor. Total 60 patients (aged 18-50 years) were selected for the study during the period of June 2007 to May 2008 in the department of Dermatology of three different hospitals in Bangladesh. Cases having with extensive involvement, diagnosed clinically and confirmed by wood's lamp and KOH microscopy were taken. Patients were randomly allocated into equal groups. Group A was given single dose 400 mg itraconazole and Group B was given 7 day 200 mg daily itraconazole. Fifty three (88%) male and 7(12%) female were included in the study. The mean age of group A was 32.37+/-9 years and in group B 33.23+/-8 years. The mean duration of the disease in group A was 2.63+/-2 months and 2.76+/-2 months in group B. In group A clinical responders was found cure 22(73.33%) and improvement 5(16.33%) and in group B it was found cure 24(79.99%) and improvement 4(13.33%). The measure at the End point (EP1) equals to 90% response and in-group B it was found cure 24 (79.99%) and improvement 4(13.33%). (Here the End point EP2) equals to 93.33%. The EP clinical analysis however shows 91.66% response. Both single dose and 7 day daily dose of itraconazole can be effective in the treatment of tinea versicolor with extensive involvement but single dose appears to be better for improving compliance and decreasing the cost of treatment.

    ABSTRACT: This study investigated the effects of substrates and supplemental feeding on growth and production of tilapia (Oreochromis niloticus) and freshwater prawn (Macrobrachium rosenbergii) in a polyculture system. On actual farms, four treatments were evaluated in triplicate: substrate plus feed (herein called treatment SF), no substrate plus feed (S0F), substrate plus no feed (SF0) and no feed and substrate (control). All ponds were stocked with tilapia and freshwater prawn juveniles at a stocking density of 30,000 ha−1 with the ratio of 75% tilapia and 25% freshwater prawn. In the substrate-based system bamboo poles provided 60% additional surface area (compared to pond surface area) for periphyton growth. A commercial 25% protein diet fed at 2–3% tilapia body weight per day was applied. The feed conversion ratio (FCR) of tilapia was significantly higher in the treatment with substrate and feeding (SF) than in the treatment with only feeding (S0F). The combined net yields varied significantly (P<0.05) among four treatments and productions were 59, 48 and 47% higher in ponds with substrate and feed (SF), feed alone (S0F) and substrate alone (SF0), respectively, compared to the control. The combined net yields of tilapia and prawn in the treatments S0F and SF0 were similar (P>0.05). 29 genera of algae and 9 genera of zooplankton were identified from pond water and it showed significant (P<0.05) differences for Chlorophyceae, Bacillariophyceae and Cyanophyceae in the treatment SF compared to the control. There were no significant (P>0.05) differences for periphyton biomass in terms of ash free dry matter (AFDM), chlorophyll a and phaeophytin a in substrate based systems. The net profit margin was highest in treatment SF0 (57%) followed by SF (51%), S0F (50%) and the control (24%).

    ABSTRACT: The present research investigated the effect of addition of tilapia and substrates for periphyton development on pond ecology, production and economic performances in C/N controlled freshwater prawn farming system. The absence and presence (0 and 0.5 individual m− 2) of tilapia were investigated in 40 m2 ponds stocked with 3 prawn juveniles (individual weight 5 g) m− 2 with or without added substrates for periphyton development. A locally formulated and prepared feed containing 30% crude protein (C/N ratio10) was applied daily, initially at 10% of the prawn stocked biomass and was gradually reduced to 3% of prawn biomass. Tapioca starch was used as carbohydrate source for increasing the C/N ratio from 10 (as in feed) to 20 and was applied to the water column separately from the feed. Addition of periphyton substrates significantly reduced the inorganic N-species (NH3–N, NO2–N and NO3–N) in the water column. It decreased the abundance of plankton in the overlying water and increased the abundance of benthic macroinvertebrates. The abundance of periphytic algae and periphyton biomass (dry matter, ash free dry matter and chlorophyll a) were significantly higher in tilapia free ponds compared to tilapia added ponds. Both substrates and tilapia had significant effects on feed conversion ratio (FCR) of freshwater prawn: substrates decreased FCR by 14% while tilapia addition increased it by 16%. The addition of substrates did not influence prawn and tilapia size at harvest but improved the survival of prawn from 54 to 77%. Substrates contributed 44% and 19% higher net yield of prawn and tilapia, respectively whereas tilapia addition decreased the net yield of prawn by 14%. The economic analysis showed that addition of tilapia and periphyton substrates jointly improved the benefit–cost ratio. Addition of tilapia and periphyton substrates in C/N controlled system benefited the freshwater prawn culture practices through (1) reducing toxic inorganic nitrogenous compounds in water (2) enhancing the utilization of natural foods (3) improving survival, production and economic benefit.

    ABSTRACT: An on-farm trial was carried out in 12 earthen ponds at the Montala Village, Muktagacha, Mymensingh for a period of 4 months (July-October 2003) to assess the potential of increasing pond fish production by growing dhaincha (Sesbania rostrata) in the pond bottom. The experiment consisted of four treatments each with three replications with an object of replacement for the use of fertilizers in fish production. In treatment-I (T1) dhaincha without fertilizer, in treatment-II (T2) dhaincha with 25% fertilizer, in treatment-III dhaincha with 50% fertilizer and in treatment-IV (T4) dhaincha with 100% fertilizer were used. Dhaincha seed was sown at 100 gx40m-2 from bottom to dike. After 50 days of sowing dhaincha on the moist pond bottom, lime and fertilizer were used and fish fry were released after watering the ponds. The stocking density of rohu (Labeo rohita), catla (Catla catla), mrigal (Cirrhinus cirrhihosus), silver carp (Hypophthalmichthys molitrix) and Thai sarputi (Puntius gonionotus) was 12,350 fishxha-1 in all treatments. Fertilization was done at 100 g urea + 100 g TSPx40 m-2, 50 g urea + 50 g TSPx40 m-2, 25 g urea + 25 g TSPx40 m-2 in treatments T4, T3 and T2, respectively and no fertilization in T1. Some of the water quality parameters showed significant difference among different treatments, but most parameters were found within the suitable ranges for pond fish culture. Recorded periphyton groups were composed of Bacillariophyceae (9), Chlorophyceae (10), Euglenophyceae (2), Cyanophyceae (6), Crustacea (2) and Rotifera (3). Among these groups Cyanophyceae was the most abundant in number of which Microcystis was most abundant. The mean abundance of Cyanophyceae in treatments T1, T2, T3 and T4 were 62,099±7,159 cellsxcm-2, 59,259±7,941 cellsxcm-2, 53,827±12,983 cellsxcm-2 and 56,419±13,015 cellsxcm-2, respectively. The mean survival rate in treatments T1, T2, T3 and T4 were 82.14, 84.53, 82.83 and 83.23%, respectively. The highest growth rate of fish observed after one month of stocking and then growth rate was decreased gradually. Highest total net fish yield was recorded in T2 (1,619 kgxha-1), where 25% fertilizer was used along with Dhaincha followed by T1 (1,249 kgxha-1), T3 (1,421 kgxha-1) and T4 (1,268 kgxha-1). It can be concluded that use of dhaincha along with 25% fertilizer would be a better environment friendly management system for pond aquaculture than the only fertilizer dependent culture practice.
