ABSTRACT
X-linked adrenoleukodystrophy (X-ALD) is a genetic disease with a variety of phenotypic expression. This is the first case report of X-AMN/ALD in two brothers in Bangladesh confirmed by raised VLCFA. Our index patient of 19 years presented on 2014 with adrenal insufficiency, after one year developed progressive spastic paraparesis along with cognitive declination and behavioral abnormality. His only brother was clinically asymptomatic at presentation with Addison’s disease and extensor planter reflexes. After three years of follow up, index patient became bed bound with slurred speech, urinary urge incontinence and his brother developed spastic paraparesis with cognitive impairment. None had gonadal impairment. Follow up MRI after three years revealed lesion in brainstem in both along with atrophy of thoracic segment of spinal cord in index patient and cerebellum, internal capsule involvement in his brother. Both were of pure AMN variety but due to presence of cognitive impairment and behavioral abnormality they can be categorized as cerebral variety of AMN. On 2023, our index patient is still surviving with major functional disability and his brother died on 2019, 5 years of initial diagnosis.
ABSTRACT
Abstract Tuberculosis is a communicable disease with high morbidity and mortality rates in developing countries. The study's primary objective is to compare conventional methods such as acid-fast bacillus (AFB) culture and microscopy with rapid diagnostic methods. The secondary objective is to compare histopathological and microbiological findings in suspected patients with tubercular lymphadenitis. A total of 111 samples (August 2018 to September 2019) of lymph nodes were processed for AFB microscopy, AFB cultures, drug-susceptibility testing (DST), histopathology, and Xpert Mycobacterium Tuberculosis (MTB)/resistance to Rifampin (RIF) assays. Out of 111 lymph node samples, 6 (5.4%) were positive for AFB smear microscopy, 84 (75.6%) were positive for AFB culture, 80 (70.7%) were positive on Gene Xpert, and 102 (91.8%) were indicative of tuberculosis for histopathology studies. Mycobacteria growth indicator tube (MGIT) culture positivity was 84 (75.6%) higher than solid Lowenstein-Jensen (LJ) culture 74 (66.6%). Positive cultures underwent phenotypic DST. Two cases were Multidrug-resistant (MDR) on DST, while three cases were Rifampicin resistant on Gene Xpert. The sensitivity of Genexpert was (62%) against the conventional AFB culture method. The poor performance of conventional lymphadenitis diagnostic methods requires early and accurate diagnostic methodology. Xpert MTB/RIF test can help in the treatment of multidrug-resistant TB cases. Nonetheless, rapid and conventional methods should be used for complete isolation of Mycobacterium tuberculosis.
Resumo A tuberculose é uma doença transmissível com altas taxas de morbimortalidade nos países em desenvolvimento. O objetivo principal do estudo é comparar métodos convencionais, como cultura de bacilo álcool-ácido resistente (BAAR) e microscopia, com métodos de diagnóstico rápido. O objetivo secundário é comparar os achados histopatológicos e microbiológicos em pacientes com suspeita de linfadenite tubercular. Um total de 111 amostras (agosto de 2018 a setembro de 2019) de gânglios linfáticos foi processado para microscopia de AFB, culturas de AFB, teste de susceptibilidade a drogas (DST), histopatologia e Xpert Mycobacterium tuberculosis (MTB)/ensaios de resistência à rifampicina (RIF). Das 111 amostras de linfonodos, 6 (5,4%) foram positivas para baciloscopia de AFB, 84 (75,6%) foram positivas para cultura de AFB, 80 (70,7%) foram positivas para o GeneXpert e 102 (91,8%) foram indicativas de tuberculose para estudos histopatológicos. A positividade da cultura do tubo indicador de crescimento de micobactérias (MGIT) foi 84 (75,6%), maior que a cultura sólida de Lowenstein-Jensen (LJ), 74 (66,6%). As culturas positivas foram submetidas a DST fenotípico. Dois casos eram multirresistentes (MDR) ao DST, enquanto três casos eram resistentes à rifampicina no GeneXpert. A sensibilidade do GeneXpert foi 62% contra o método convencional de cultura AFB. O fraco desempenho dos métodos convencionais de diagnóstico de linfadenite requer metodologia de diagnóstico precoce e precisa. O teste Xpert MTB/RIF pode ajudar no tratamento de casos de tuberculose multirresistente. No entanto, métodos rápidos e convencionais devem ser usados para o isolamento completo do Mycobacterium tuberculosis.

Root deformation (RD) caused by errors in the pricking out process are irreversible and very difficult to detect in container-grown seedlings at the time of planting in the field. The objective of this study was to evaluate the effects of RD on leaf gas exchange, growth, biomass allocation and mineral nutrition of G. americana seedlings during the recovery phase after soil flooding. Four-months-old seedlings, with and without RD, were flooded for 42 days and their recovery was evaluated 28 days after soil drainage. There were no significant interactions between RD and soil flooding for all leaf gas exchange, growth and mineral nutrition after soil drainage, with the exception of leaf P concentrations. In plants with no RD, the P concentration in leaves of non-flooded plants was significantly higher than that of plants with RD. Soil flooding and RD did not influence leaf or root N concentrations or whole-plant N content. RD increased the K concentration in the roots, but not in the leaves. Changes in the nutrient concentrations in leaves and roots indicate that RD may affect physiological performance of seedlings after planting in the field.
A deformação da raiz (RD) causada por erros no processo de repicagem é irreversível e difícil de detectar em mudas produzidas em embalagens no momento do plantio no campo. O objetivo deste estudo foi avaliar os efeitos do RD nas trocas gasosas foliares, crescimento, alocação de biomassa e nutrição mineral de mudas de G. americana na fase de recuperação após o alagamento do solo. Mudas com quatro meses de idade, com e sem RD, foram alagadas por 42 dias e a sua recuperação foi avaliada 28 dias após a drenagem do solo. Não houve interação significativa entre RD e alagamento do solo nas trocas gasosas foliares, crescimento e nutrição mineral após a drenagem, com exceção das concentrações de P foliar. Em plantas sem RD, a concentração de P nas folhas de plantas não alagadas foi significativamente maior que a das plantas com RD. O alagamento do solo e a RD não influenciaram as concentrações de N nas folhas e raízes, e no conteúdo de N na planta inteira. A RD aumentou a concentração de K nas raízes, mas não nas folhas. Alterações nas concentrações de nutrientes nas folhas e raízes indicam que a RD pode afetar o desempenho fisiológico das mudas após o plantio no campo.

For the proper growth of fish, it is necessary to feed the fish with a proper and balanced diet. A study was conducted to find out the effect of different protein-based diets on fingerlings of Tor putitora (mahseer). A feed with dietary protein levels of 35%, 40%, 45%, and 50% were prepared. The effect of different protein-based feed on weight gain, standard growth rate (SGR), food conversion ratio (FCR), percent weight gain, food conversion efficiency (FCE), and protein efficiency ratio (PER) was studied. An increase was observed in the growth rate with an increase in protein concentration up to 45%. The fingerlings fed a 45% protein diet shown the highest growth, followed by 50%, 40%, and 35%. The SGR value was greatest for 45% protein diet (8.56) followed by 50% and 40%, while the least values were observed for 35% protein feed (1.57). The same trend was observed for FCE. The highest PER values was observed in fishes fed 45% protein-based feed (0.65) followed by 50% (0.56), 40% (0.38) and35% (0.17). The food conversion ratio was lowest for 45% protein diet (3.41), while the greatest for 35% protein feed (16.85). It was concluded that a 45% protein-based diet was the best feed formulation for higher production of Tor putitora. However, research on the same percentage of protein diet is recommended for yearlings.
Para o bom crescimento dos peixes, é necessário alimentá-los com uma alimentação adequada e balanceada. Um estudo foi realizado para descobrir o efeito de diferentes dietas à base de proteínas em alevinos de Tor putitora (mahseer). Foi preparado um alimento com níveis de proteína dietética de 35%, 40%, 45% e 50%. O efeito de diferentes alimentos à base de proteína no ganho de peso, taxa de crescimento padrão (SGR), taxa de conversão alimentar (FCR), ganho de peso percentual, eficiência de conversão alimentar (FCE) e taxa de eficiência proteica (PER) foi estudado. Foi observado um aumento na taxa de crescimento com um aumento na concentração de proteína de até 45%. Os alevinos alimentados com dieta de 45% de proteína apresentaram o maior crescimento, seguidos de 50%, 40% e 35%. O valor de SGR foi maior para dieta com 45% de proteína (8,56), seguido de 50% e 40%, enquanto os menores valores foram observados para ração com 35% de proteína (1,57). A mesma tendência foi observada para FCE. Os maiores valores de PER foram observados em peixes alimentados com 45% de ração à base de proteína (0,65), seguido por 50% (0,56), 40% (0,38) e 35% (0,17). A taxa de conversão alimentar foi menor para a dieta com 45% de proteína (3,41), enquanto a maior para a dieta com 35% de proteína (16,85). Concluiu-se que a dieta à base de proteína de 45% foi a melhor formulação alimentar para maior produção de Tor putitora. No entanto, a pesquisa sobre a mesma porcentagem de dieta proteica é recomendada para animais de um ano.

ABSTRACT
Abstract Snow trout (Schizothorax plagiostomus) is an economically important freshwater fish, mostly found in northern areas of water reservoirs of Pakistan. The current study was conducted in River Swat to analyze the bioaccumulation of heavy metals (Pb, Cr, Ni, and Zn) in tissues of Schizothorax plagiostomus. Tissues were extracted and dissolved in perchloric acid (HClO4) and nitric acid (HNO3) along with hotplate. The heavy metals, zinc (Zn), lead (Pb), chromium (Cr), and Nickel (Ni) were determined using Perkin Elmer 2380 atomic absorption spectrophotometer. Results shows great variation in the content of the metal related to tissue type and sampling sites. A high concentration of bioaccumulation was reported at Charbagh, whereas lowest at Odigram: Charbagh>Landakai>Odigram. In the same way, Cr was the most accumulated heavy metal followed by lead, nickel, and Zinc:
Resumo A truta das neves (Schizothorax plagiostomus) é um peixe de água doce economicamente importante, encontrado principalmente nas áreas ao norte de reservatórios de água do Paquistão. O presente estudo foi realizado em River Swat para analisar a bioacumulação de metais pesados (Pb, Cr, Ni e Zn) em tecidos de Schizothorax plagiostomus. Os tecidos foram extraídos e dissolvidos em ácido perclórico (HClO4) e ácido nítrico (HNO3) com placa de aquecimento.

ABSTRACT
Abstract For the proper growth of fish, it is necessary to feed the fish with a proper and balanced diet. A study was conducted to find out the effect of different protein-based diets on fingerlings of Tor putitora (mahseer). A feed with dietary protein levels of 35%, 40%, 45%, and 50% were prepared. The effect of different protein-based feed on weight gain, standard growth rate (SGR), food conversion ratio (FCR), percent weight gain, food conversion efficiency (FCE), and protein efficiency ratio (PER) was studied. An increase was observed in the growth rate with an increase in protein concentration up to 45%. The fingerlings fed a 45% protein diet shown the highest growth, followed by 50%, 40%, and 35%. The SGR value was greatest for 45% protein diet (8.56) followed by 50% and 40%, while the least values were observed for 35% protein feed (1.57). The same trend was observed for FCE. The highest PER values was observed in fishes fed 45% protein-based feed (0.65) followed by 50% (0.56), 40% (0.38) and35% (0.17). The food conversion ratio was lowest for 45% protein diet (3.41), while the greatest for 35% protein feed (16.85). It was concluded that a 45% protein-based diet was the best feed formulation for higher production of Tor putitora. However, research on the same percentage of protein diet is recommended for yearlings.
Resumo Para o bom crescimento dos peixes, é necessário alimentá-los com uma alimentação adequada e balanceada. Um estudo foi realizado para descobrir o efeito de diferentes dietas à base de proteínas em alevinos de Tor putitora (mahseer). Foi preparado um alimento com níveis de proteína dietética de 35%, 40%, 45% e 50%. O efeito de diferentes alimentos à base de proteína no ganho de peso, taxa de crescimento padrão (SGR), taxa de conversão alimentar (FCR), ganho de peso percentual, eficiência de conversão alimentar (FCE) e taxa de eficiência proteica (PER) foi estudado. Foi observado um aumento na taxa de crescimento com um aumento na concentração de proteína de até 45%. Os alevinos alimentados com dieta de 45% de proteína apresentaram o maior crescimento, seguidos de 50%, 40% e 35%. O valor de SGR foi maior para dieta com 45% de proteína (8,56), seguido de 50% e 40%, enquanto os menores valores foram observados para ração com 35% de proteína (1,57). A mesma tendência foi observada para FCE. Os maiores valores de PER foram observados em peixes alimentados com 45% de ração à base de proteína (0,65), seguido por 50% (0,56), 40% (0,38) e 35% (0,17). A taxa de conversão alimentar foi menor para a dieta com 45% de proteína (3,41), enquanto a maior para a dieta com 35% de proteína (16,85). Concluiu-se que a dieta à base de proteína de 45% foi a melhor formulação alimentar para maior produção de Tor putitora. No entanto, a pesquisa sobre a mesma porcentagem de dieta proteica é recomendada para animais de um ano.
ABSTRACT

ABSTRACT
The aim was to measure the prevalence of smoking and identify its potential predictors among military personnel in Kingdom of Saudi Arabia [KSA]. This cross-sectional study was carried out among military personnel in the five military regions of KSA between January 2009 and January 2011. The sample of 10,500 military personnel in the Saudi Armed Forces was equally divided among the five regions with a ratio 3:7 for officers and soldiers. A multistage stratified random sampling was used to recruit participants in the four services of the armed forces in the five regions. Information on sociodemographic characteristics with a detailed history of smoking was collected by means of a self-administered questionnaire. Bivariate analysis was used to identify the factors associated with smoking, and multiple logistic regression analysis to discover its potential predictors. About 35% of the sample was current smokers, with higher rates among soldiers. The eastern region had the highest rate [43.0%], and the southern region the lowest [27.5%]. Navy personnel had a higher risk of being current smokers [40.6%], and the air defense the lowest risk [31.0%]. Multivariate analysis identified working in the navy, and low income as positive predictors of current smoking, while residing in the southern region, older age, years of education, being married, and having an officer rank were negative [protective] factors. Smoking is prevalent among military personnel in KSA, with higher rates in the Navy and Air Force, among privates, younger age group, lower education and income, and divorced/widowed status. Measures should be taken to initiate programs on smoking cessation that involve changes in the environment that is likely to promote this habit

Anorectal malignancies that require abdominoperineal resection (APR) is very common. Laparoscopic APR can be a better option. Laparoscopic APR has been seldom studied. This study aims to evaluate perioperative and early postoperative outcomes of laparoscopic APRs performed for the treatment of ano-rectal carcinomas. Patients operated for ano-rectal carcinoma between June 2011 to June 2013 in Bangabandhu Sheikh Mujib Medical University (BSMMU) were observed. Demographics, tumor and procedure-related parameters, perioperative results, early postoperative outcomes and survival were observed. Total 22 patients were under went laparoscopic APR. Male: Female ratio was 15:7 (68.18%: 31.82%). Age range was from 30-65 years with a mean age of 36.55 years. Mean operation time was 165 minutes and mean post-operative hospital stay was 6.8 days. Overall complication rate was 45.45%. Laparoscopic APR is a safe, effective and technically feasible procedure. It can be a better operative procedure than open APR.
ABSTRACT
This cross sectional study was carried out at Bangabandhu Sheikh Mujib Medical University (BSMMU) and International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) from July 2008 to September 2009. Aim of the study was to find out the antimicrobial susceptibility profile of Helicobacter pylori isolates from dyspeptic patients. Total 224 dyspeptic patients from Out Patient Department (OPD) of BSMMU were initially enrolled after informed written consent. After upper GI endoscopy 157 patients were finally included who had erosions, ulcers or atrophic changes in the stomach or duodenum. Two biopsy samples were taken from each of them. Samples were incubated at 370C in a double gas incubator with 5%O2, 10%CO2 and 85%N2. Total 82 (52.23%) samples were found positive for H. pylori. Isolated organisms were then tested for sensitivity to Amoxicillin, Clarithromycin, Tetracycline, Levofloxacin and Metronidazole by Agar dilution method. Among 82 patients 51(62.2%) were male and 31(37.8) were female with a male:female ratio 1.6:1. Patients were categorized into two groups one having gastric or duodenal ulcer (30.5%) and other having no ulcer (69.5%). Among these isolates 92.7% were sensitive to Amoxicillin, 89% to Clarithromycin, 81.7% to Tetracycline, 80.5% to Levofloxacin and only 26.8% to Metronidazole. Beside these, 81.7% isolates were sensitive to both Amoxicillin and Clarithromycin, 74.4% to Amoxicillin and Tetracycline, 73.2% to Amoxicillin and Levofloxacin, 72% to Clarithromycin and Tetracycline, 59% to Clarithromycin and Levofloxacin and 51% to Tetracycline and Levofloxacin.
ABSTRACT
Helicobacter pylori is a Gram negative bacteria which causes chronic gastritis, peptic ulcer disease, primary B-cell gastric lymphoma, and adenocarcinoma of the stomach. There are a set of laboratory tests to diagnose H. pylori infection with a variable accuracy, they are divided into non-invasive tests and invasive tests. Non-invasive tests include serology, urea breath test (UBT) and stool antigen test (SAT). Invasive tests include rapid urease test (RUT), histology and culture. This cross sectional study was carried out in the Department of Gastroenterology, Bangabandhu Sheikh Mujib Medical University (BSMMU) and H. pylori laboratory of International Centre for Diarrhoeal Disease Research, Bangladesh (ICDDR,B) from July 2008 to September 2009 to evaluate the efficacy of RUT, SAT and Culture as a diagnostic tool for H. pylori. Dyspeptic patients were collected from outpatient department of BSMMU. Out of 224 dyspeptic patients 149 patients had ulcers or erosions in the stomach or duodenum. Stool sample could be collected from 139 patients. RUT has sensitivity of 100%, specificity 80.28%, positive predictive value 85% and negative predictive value 100%. Regarding culture, sensitivity is 100%, specificity 94.37%, positive predictive value 95% and negative predictive value 100%. Stool antigen test has sensitivity 95.94%, specificity 92.31%,positive predictive value 93% and negative predictive value 95%.
ABSTRACT
Strongyloides stercoralis is a common intestinal parasite in tropics and subtropics. In Bangladesh, prevalence is likely to be high due to poor sanitation. Clinical presentations are frequently nonspecific. However, in immunosuppressed individuals, infection becomes overwhelming and may disseminate and results in high rates of mortality. Unless a high index of suspicion, this readily treatable disease may be missed. Here we report a case of hyperinfection with Strongyloides stercoralis in a patient who was on corticosteroid treatment. A 45 years old male was admitted in Gastroenterology department of Bangabandhu Sheikh Mujib Medical University (BSMMU) with the complaints of abdominal pain, vomiting and diarrhea for 2 weeks. He was on prednisolone 60 mg with omeprazole 40 mg daily for 4 weeks for his eyelid drooping prior to the development of abdominal symptoms. Physical examination revealed a severely malnourished, moderately anemic patient with muscle wasting, angular stomatitis, desquamated skins of feet and hands. Abdominal examination revealed generalized tenderness with moderate ascites. Investigations revealed Hb-7.4 gm/dl with normal WBC count (eosinophil-11% before steroid therapy), S.albumin-19gm/l with prolonged prothrombin time and hypokalemia. USG of abdomen revealed moderate ascites. Endoscopy of upper GIT showed congestion and multiple erosions in the stomach and also in the duodenum. Biopsy from the duodenum revealed adult Strongyloides stercoralis on the surface, larva and ova in the duodenal crypts. The patient was treated with 10 days of oral ivermectin along with blood transfusion, correction of nutritional status and electrolyte imbalance. Patient was discharged home after a total of 20 days of hospitalization.
ABSTRACT
Chronic Kidney Disease (CKD) presents with an array of cutaneous manifestations. Newer changes are being described since the advent of haemodialysis, which prolongs the life expectancy, giving time for these changes to manifest. This cross sectional study was performed in 100 cases of CKD admitted in nephrology department of Dhaka Medical College Hospital (DMCH) and Bangabandhu Sheikh Mujib Medical University (BSMMU) from April 2008 to August 2008 to evaluate the prevalence of dermatologic problems. Among them most belong to 2nd to 5th decade, 68 are male and rests are female. Glomerulonephritis (44%), Diabetes mellitus (22%), Obstructive uropathy (13%) and Hypertensive nephropathy (12%) are found common causes of CKD. Among these patients 38% patients were treated with conservative treatment, 31% with intermittent peritoneal dialysis (IPD), 19% with haemodialysis and 12% with some form of immunosuppressive therapy. Total 88% of study population had some form of skin disorder; pallor was the most common (82%), while xerosis (61%), pruritus (53%), pigmentation (37%) and bacterial infection (37%) were other common problems. Purpura and fungal infection was 29% and 27% respectively. Viral infection (9%), dermatitis (4%), gynaecomastia (1%), kyrle's disease (3%) are relatively less common findings. Lindsay's nail was seen in 23% of patients and was more prevalent in glomerulonephritis and diabetic patients with prevalence of 13% and 9% respectively. Other nail changes included koilonychia (4%), subungual hyperkeratosis (1%), splinter hemorrhages (3%) onychomycosis (8%) and Beau's lines (1%). So, CKD is associated with a complex array of cutaneous manifestations caused either by the disease or by treatment.
