RESUMO

Magnesium depletion has a negative impact on glucose homeostasis and insulin sensitivity in diabetic patients. Low plasma magnesium concentration is a highly specific indicator of poor magnesium status. This case control study was conducted in Mymensingh Medical College Hospital, Bangladesh, from May 2011 to April 2012. This study was done to assess the serum magnesium level in diabetic and non-diabetic patients and to find out the association between serum magnesium, blood glucose and duration of diabetes mellitus. Serum magnesium concentrations were determined in 50 diabetics and 50 age and sex matched non-diabetic patients or attendants for controls. Among the case and control group 32 were male and 18 were female. Mean age of control group was 54.42±2.33 and study group was 55.78±2.43 years. Duration of diabetes of case group in which 50% of patients have diabetes for up to 4 years, 18% of patients have diabetes for 5-9 years, 5% of patients have for 10-14 years and 2% of patients have diabetes for 15 years and above. Serum magnesium concentrations below the normal reference range for study group was 44% and control group was 6%. The mean serum magnesium level of study group was 0.70±0.01mmol/L and that of control group was 0.83±0.02mmol/L. So, the difference in serum magnesium level between two groups were statistically highly significant (p = 0.001). Correlation between FBS and SML of study group, which is negative (r = - 0.182). There is opposite relation among the characteristics as r is negative. And also correlation between 2HAFB and SML of study group, which is negative (r = - 0.06). There is opposite relation among the characteristics as r is negative.

RESUMO

SARS COV 2 raised immense agony to everyone. As health care workers remains direct contact with patients, they are vulnerable to mental health disorder. The study was done to identify mental health status of health care providers of Bangladesh. It was a cross sectional web based survey among health care providers of bangladesh. A structured web based questionnaire was prepared both in Bangla and English version for better understanding. Total 2594 health care workers responded to online survey. Male were 1303(50.2%) and female were 1291(49.8%). Occupational demography shows 98.5% were physicians. Mean value of patient health questionnaire 9 (PHQ9) and generalized anxiety disorder (GAD) were 8.43±6.082 and 8.27±5.234 respectively among healthcare providers. To overcome anxiety and depression, 93.4% of HCW didn't receive any psychological material and 85.6% HCW didn't find physiological resources even through media. Despite many lacking, healthcare workers were resilient in our study.

RESUMO

Cataracts have been infrequently reported in Fibrocalculous pancreatic diabetes (FCPD) which is a form of diabetes secondary to chronic, non-alcoholic pancreatitis in tropical countries. A retrospective study was carried out to find out frequency of cataracts in children and adolescents with FCPD admitted in the Paediatric Unit at Bangladesh Institute of Research and Rehabilitation on Diabetes, Endocrine and Metabolic disorders (BIRDEM). A total of 83 patients with FCPD were admitted during the study period of 2000 to 2007. Among them twenty patients (24%) had bilateral cataracts who were enrolled in the study. Mean age at the onset of diabetes was 13.9±1.7 years. There was female preponderance. Ninety percent patients were girls. There was longer duration of symptoms in all patients. Mean duration of symptoms before diagnosis was 15.0±10.2 months. All patients had hyperglycaemia, mean HbA1c value was 18.4±5.1. Most of the patients had snowflake type cortical deposits and posterior subcapsular cataract.

RESUMO

Severe hypertriglyceridemia can cause the deposit of lipids in the dermis (eruptive xanthomas) and in the retina (lipemia retinalis). Lipemia retinalis and eruptive xanthoma are occasionally seen in patients with diabetes mellitus and are thought to be due to abnormalities in the serum lipid fractions. Here a 15 year's old girl presented with typical symptoms of diabetes with skin lesions over hands and feet. On examination skin lesions were non-tender yellow papules with creamy-colored centers on extensor surfaces of the arms, hands and feet. Ophthalmoscopic examination showed creamy white retinal vessels with a faded pinkish white retinal back ground both in the periphery and posterior pole of the retina. Laboratory findings showed a grossly lipemic serum with markedly elevated serum levels of triglycerides 8869mg/dl cholesterol 498mg/dl. Her fasting blood glucose was 20.8mmol/l, 2 hours after breakfast was 50.5mmol/l and HbA1c was 14.6%. Eruptive xanthomas and lipaemia retinalis can occur in primary and secondary hyperlipoproteinemias, therefore a careful personal and family history as well as laboratory investigations is recommended in order to detect an underlying cause.

RESUMO

The study was undertaken to see the prevalence of impaired glucose tolerance among children and adolescents with obesity, attending the Paediatric Endocrine OPD, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic disorders (BIRDEM), Dhaka, Bangladesh. A cross sectional study from January 2006 to December 2008 was conducted among obese children and adolescents (6-18 years). Children with any other endocrine disorder, dysmorphism/syndrome were excluded. Obesity was defined as BMI ≥ 95th percentile for age and sex using CDC growth chart. Children underwent two hours oral glucose tolerance test with 1.75 gm/kg or 75 gm of glucose, anthropometric and blood pressure measurement. Fasting serum insulin and lipid profile were measured. Impaired glucose tolerance (IGT) was defined as fasting plasma glucose (FPG) <7 mmol/L and 2 hours post glucose load ≥ 7.8 mmol/L to <11.1 mmol/L. Diabetes mellitus (DM) was defined as FPG ≥ 7 mmol/L or 2 hours post glucose load ≥ 11.1 mmol/L. Homeostasis model assessment was used to estimate insulin resistance. A total of 161 children presented with obesity. Male to female ratio was 1.3:1. Mean age was 10.3 ± 2 .5 years. Mean BMI was 27.86 ± 4.1 kg/m². IGT was found in 16.9% of children and adolescents. In children aged 6-10 years IGT was detected in 16.1% and in adolescents aged 11-18 years IGT was detected in 20%. Diabetes mellitus was detected in 2.1% of subjects, all were adolescents. Serum fasting insulin and hip circumference were significantly higher among children and adolescents with IGT compared to that of normal glucose tolerance. The high rate of IGT among obese children and adolescents is of concern. Factors contributing towards obesity needs to be identified and strategies should be planned for prevention and management of this health problem.

RESUMO

This cross sectional descriptive type of observational study was designed to see the prevalence of NAFLD among school children of Sylhet, Bangladesh from December 2019 to January 2020. School children of three private schools of Sylhet City were randomly selected. Socio-demographic data and anthropometric measurement of them were recorded. Then they underwent screening sonologically for NAFLD. Data analysis was done using SPSS version 20.0. P value <0.05 was taken as significant. Total 174 students, boys 99(56.9%) and girls 75(43.1%) were included. Age of them varied from nine years to 17 years (mean 13.408). In this series 82(47.1%), 52(29.9%) and 40(23.0%) were of normal weight, overweight and obese children respectively. In this study 29(16.7%) children had NAFLD and seven (4.0%) had biliary sludge in gall bladder. NAFLD was significantly higher among children with higher BMI (p=0.00). Female sex, children consuming fast food and playing video games were about two times more prone to develop NAFLD. Biliary sludge was found significantly higher among children consuming fast food (p=0.02). NAFLD among school going children is not uncommon. Higher BMI is a significant risk factor of developing NAFLD. Girls and children consuming fast food and playing video games also are more prone to develop NAFLD. Prevalence of sludge in gall bladder is low among school children.

RESUMO

This cross sectional study was conducted in Paediatric Endocrine Outpatient Department of BIRDEM General Hospital, a tertiary care centre in Dhaka, Bangladesh among patients diagnosed with congenital adrenal hyperplasia (CAH) from January 2005 to December 2018. The study was aimed to find out the clinical and laboratory profile of all patients at presentation diagnosed with CAH during the study period. Data were obtained by reviewing the medical records of the patients. Total 102 children with CAH were diagnosed during the study period. Among them 68 were female and 34 were male (female to male ratio of 2:1). Median age was 3.5 month (range 0.2-158 month) and 5.5 month (range 1-108 month) in female and male respectively (p=0.42). Family history was available in 93 patients. Consanguinity was present in 16(17.2%), history of sib death in 12(12.9%), other family members were affected in 8(8.6%). Sixty patient (58.8%) had salt-wasting (SW), 39(38.2%) had simple virilizing (SV) and 3(2.9%) had non- classic form of CAH. Median age of presentation was 2 month (range 0.2-70 month) and 42 month (range 0.8-158 month) in SW and SV group respectively (p=0.001) and 119 month (range 108-152 month) in non- classic group. Common presentations were: genital ambiguity (64.7%), vomiting (46.5%), failure to thrive (41.6%), features of early puberty (precocious pseudopuberty) (24.5%), diarrhea (12.0%). Hyperpigmentation was noted in 49.0% of patients. Among the salt-wasting type in male failure to thrive (FTT) was the most common presentation (83.3%), followed by vomiting (75.0%). In female genital ambiguity was the commonest presentation (97.2%), followed by vomiting (77.1%). Among the simple virilizing type in male early puberty was the commonest presentation (100%) and genital ambiguity was the presenting feature in all the female (100.0%).

RESUMO

Objectives: To assess the protective effect of L-carnitine in reducing cisplatin toxicity via estimating biochemical tests, histomorphometric, and immunohistochemistry (IHC) of ß-catenin and cyclin D. Materials and Methods: Fifteen adult male rabbits were used in this study and allocated into 3 groups; Group 1 (Control negative), rabbits of this group were not given any treatment. In group 2, the animals were injected with cisplatin single-dose/per week. Group 3 rabbits were treated with Cisplatin+L-carnitine orally by gavage tube for 29 days. At the end of the experiments, blood samples from all rabbits were taken from the earlobe, and then the biochemical test was done, the kidney and tissue sections were prepared for both H& E and IHC for both ß-catenin and cyclin D genes. Results: Treatment with L-carnitine reduced the injury effect of cisplatin via a decline in serum creatinine, urea, bilirubin, GPT, GOP, and ALP significantly (P<0.05). Also, administration of LC attenuates the histopathologic abnormality in the kidney (15.71% vs 85.18%) and liver (score 3 vs 15 ) induced by cisplatin. L-carnitine elevates the expression of ß-catenin and cyclin D in renal and hepatic parenchyma by diffuse, moderate-strong positivity vs cisplatin that showed local-weak staining. Conclusion: These findings imply that L-carnitine, by its pleiotropic actions in activating Wnt signaling, alleviates cisplatin-induced renal and hepatic destruction. It might be a method of preventing cisplatin-related nephrotoxicity and hepatotoxicity.

RESUMO

There are different types of gallbladder polyps having variable morphology and nature. Symptoms are vague and mostly diagnosed incidentally on abdominal ultrasound. Risk factors are many. Indications of surgery are not clearly understood due to lack of clinical evidence. This study was carried out to analyze the management of gallbladder polyp in our settings and review of available evidence. Patients who underwent clip less mini laparoscopic cholecystectomy for gallbladder polyp were included. Clinical data including short history, age, gender, parity, lab tests, ultrasound report and macroscopy were recorded during surgery. Histopathology reports collected later. Total of 112 patients with mean age 42.6 years (range 22-82), 74 of whom were female. Most of them (46.42%) were asymptomatic. Single polyp was in 69, multiple in 32 and polyp with stone in 8 patients. Sessile polyp was 74.10%. Average polyp size was 7.6mm. Cholesterol polyp was in 82 patients. Four out of 5 malignant polyps were single and sessile. Abdominal ultrasound is the mainstay of diagnosis of gallbladder polyp but size, location, morphology, number and presence of associated gallstone has to be mentioned. Symptomatic gallbladder polyp benefited from surgery. Polyps more than 6mm, single and sessile morphology above the age 50 should undergo cholecystectomy.

RESUMO

With an objective to understand acquisition of innate immunity in bovine neonates, we analyzed perinatal expression of cytokine, adhesion molecule and complement component genes involved in innate and adaptive immune functions. Statistically robust transcriptomic analysis of 27 cytokines showed low IL1B, IL2 and IL7 but high IL23, TGFB1 and TGFB2 expression in bovine neonates post-birth. Unlike mice and humans, no TH2 polarizing cytokine expression occurs in bovine neonates. Further, TH17 and Treg differentiation in bovine neonates may differ from other species like mice and humans. Decreased IL7, IL23R, CXCR3 and increased TGFB1 and TGFB2 expression provides an immunosuppressive environment in the bovine neonate at birth. Transcriptomic analysis of 31 adhesion molecules showed rapid increase in ITGAL expression within a week post-birth in bovine neonates that permits acquisition of innate cytotoxic functions by granulocytes (antibody-mediated), cytotoxic T and NK cells. However, innate immune functions involving phagocytosis and platelet aggregation are deficient in bovine neonates at birth. Of twenty-seven, 18 complement component genes show no significant differential gene expression in neonates post-birth. But low expression of C1QA, C1QB, CQC, C1R and C2 compromises classical and lectin complement pathways mediated lytic function in bovine neonates. The complement-mediated cytotoxic functions, however, normalize between days 7 and 28 post-birth. To conclude, bovine neonate is immunosuppressed and deficient in innate immune competence at birth. Such differences with regard to global innate immune deficiency and lack of TH2 polarization in bovine neonates have profound implications for designing vaccines to prevent neonatal infections. To conclude, species-specific unique characteristics of developing innate and adaptive immune system need to be taken into consideration while designing new immunization strategies to prevent neonatal mortality from infections.

RESUMO

A cross sectional study was conducted in September 2006 in one of the private schools in Dhaka, Bangladesh to see the prevalence of obesity among affluent school children and adolescents. Informed consent was taken from school authority to take anthropometric measurement of all school children. Standing height was measured with a stadiometer and weight with a bathroom scale. Waist and hip circumference were measured with a measuring tape. The body mass index (BMI) was calculated using weight in kilogram/(height in meter)2 formula. Obesity was defined as BMI≥95th percentile for age and sex, over weight as BMI≥85th percentile for age and sex, normal weight as BMI between 5th and 84th percentile and underweight as BMI <5th percentile. Official centers for disease control (CDC) growth chart for boys and girls age 2-20 years was used. Children and adolescents were divided into group 1(3-5 years), Group 2(6-9years), group 3(10-13 years) and group 4(14-18 years). There were a total of 468 children and adolescents (male 266, female 202). In group 1 there were 110 children, in group 2 there were177 children, in group 3 and 4 there were 149 and 32 adolescents respectively. The prevalence of obesity was 17.9%, higher among males (19.9%), compared to females (15.3%). Obesity was highest (27.7%) in group 2, 14.5% in group 1, 10.7% in group 3 and 9.4% in group 4.

RESUMO

Antibody diversification in IgM and IgG antibodies was analyzed in an 18-month old bovine (Bos taurus) suffering from naturally occurring chronic and recurrent infections due to bovine leukocyte adhesion deficiency (BLAD). The BLAD, involving impaired leukocyte beta2 integrin expression on leukocytes, develops due to a single point mutation in conserved region of the CD18 gene resulting in substitution of aspartic acid128 with glycine (D128G). Twenty four VDJCmu and 25 VDJCgamma recombinations from randomly constructed cDNA libraries, originating from peripheral blood lymphocytes, were examined for the variable-region structural characteristics in IgM and IgG antibody isotypes. These analyses led to conclude that: (a) expression of exceptionally long CDR3H is isotype restricted to cattle IgM antibody; (b) VDJ recombinations encoding IgM with exceptionally long CDR3H undergo clonal selection and affinity maturation via somatic mutations similar to conventional antibodies; (c) somatic mutations contribute significantly to both IgM and IgG antibody diversification but significant differences exist in the patterns of 'hot spot' in the FR1, FR3 and CDR1H and, also, position-dependant amino acid diversity; and (d) transition nucleotide substitutions predominate over transversions in both VDJCmu and VDJCgamma recombinations consistent with the evolutionary conservation of somatic mutation machinery. Overall, these studies suggest that both somatic mutations and exceptional CDR3H size generation contribute to IgM and IgG antibody diversification in cattle during the development of immune response to naturally occurring chronic and multiple microbial infections.

RESUMO

Cleidocranial dysplasia (CCD) is a disorder that affects mostly those bones which derived from endochrondal and intramembranous ossification, such as the cranium and the clavicles. CCD is present at a frequency of one in one million individuals. Over 500 cases have been reported. A 13 years old boy reported in the Paediatric Endocrinology outpatient department, Bangladesh Institute of Research and Rehabilitation on Diabetes, Endocrine and Metabolic Disorders (BIRDEM) on 6th April 2006 with complaints of not growing according to his age, a wide gap over the head since birth and delayed shedding of primary teeth and also eruption of secondary teeth. The boy had elongated facies with midfacial hypoplasia, depressed nasal bridge with hypertelorism. His anterior fontanelle was open about 3/1.5 cm. He had short clavicle and his shoulders could be easily apposed. Radiological findings showed anterior fontanellle and sutures were open and widened, all decidual teeth were intact and all secondary teeth were impacted beneath the primary teeth and hypoplastic clavicle. He was diagnosed as a case of Cleidocranial Dysplasia on the basis of history, clinical examination and investigation.

RESUMO

A seven year and ten months old girl presented with cyclic vaginal bleeding and a huge abdominopelvic mass. She had clinical features of hypothyroidism. The investigation results were consistent with the diagnosis of primary hypothyroidism with precocious puberty. She also had bilaterally enlarged cystic ovaries on CT scan of abdomen and CT scan of brain showed pituitary macroadenoma. After starting treatment with thyroxine, patient became euthyroid and her general condition improved. Treatment with thyroxine alone halted the cyclic vaginal bleeding, led to rapid resolution of the ovarian cysts and regression of the pituitary mass.

RESUMO

Congestive heart failure is the one of the major cardiovascular disorder that is increasing in incidence and cause of death globally. Mortality rate has increased 40%-50% in advanced cardiac failure and 15%-25% in mild to moderate cardiac failure within one year of diagnosis. There is no established biochemical marker for the diagnosis, prognosis and staging of heart failure. Cardiac Troponin I may be a novel useful tool in identifying patients with Heart failure who are at increased risk for progressive ventricular dysfunction and death. Thirty six congestive heart failure cases and thirty six healthy controls were included in this study and serum cardiac troponin I and Ejection fraction were measured. All the study subjects were grouped according to the NYHA class they belong. Cardiac troponin I was significantly higher in CHF cases than the controls. Troponin I also significantly differed among groups. EF of cases was significantly lower than the controls and also differed among groups. A significant negative correlation between cardiac troponin I and progressive decline of ejection fraction was evident in this study. Cardiac troponin I increased progressively with progression of heart failure. Thus, Cardiac troponin I could be used to stratify patients undergoing heart failure in to high and low risk groups for future cardiac events. Cardiac troponin I could also be used as a very important marker for the prognosis of the patients with congestive heart failure.

RESUMO

With an objective to understand natural development of bovine neonatal immunity, we analyzed 18 RNA-seq libraries from peripheral blood lymphocytes of three neonatal calves pre- (day 0) and post-colostrum (7, 14 and 28) uptake as compared to their dams. A significant global shift in neonatal transcriptome occurs within first week post-birth, in contrast to dams, with an upregulation of 717 genes. Global pathway analysis of the transcriptome revealed 110 differentially expressed immune-related genes, such as, complement, MHCII, chemokine receptors, defensins and cytokines, at birth. The signaling molecules (LAX1, BLK) and transcription factors (GATA3, FOXP3) are expressed at high levels. High expression of GATA3 transcription factor at birth seems to skew the neonatal immune response towards TH2 type. The high levels of T-cell signaling molecules, CD3G and CD3D, at birth are important in neonatal T cell development. Unlike adults, IGKC expression is high in the neonates where IGKV12 is preferentially expressed at birth. But IGLC is predominant in both neonates and adult where IGLV3.4 is preferentially expressed in B cells at birth. Both IGHM and IGHD are expressed at birth and IGHM achieves adult levels by day 7. This is followed by IGHA and IGHG expression 14-28 days post-birth. Importantly, preferential expression of IGHV1S1(BF4E9) and longest IGHD2(DH2) genes that encode immunoglobulin with exceptionally long CDR3H at birth indicates their critical role, as B cell antigen receptor, in the B cell development via idiotype-anti-idiotype interactions. The transcriptome signatures described here permit assessment bovine neonatal immunocompetence. Bovine neonates acquire innate and IgM-mediated humoral immunocompetence within first week post-birth.

RESUMO

The use of touch by health workers to detect hypothermia was examined in 250 newborns in Nepal. Palpation of the feet shows fair interobserver agreement (kappa = 0.4-0.7) and high sensitivity (>80%) but low specificity (36%-74%) compared with axillary thermometry.

RESUMO

The aim of this study was to examine the prevalence of maternal and newborn-care practices among women reporting a birth in the previous year in three districts in different divisions of Bangladesh. In 2003, 6,785 women, who had delivered a newborn infant in the previous year, across three districts in Bangladesh, were interviewed. Overall, less than half of the women received any antenatal care, and 11% received a minimum of four check-ups. Only 18% took iron tablets for at least four months during pregnancy. Over 90% of the 6,785 deliveries took place at home, and only 11% were attended either by a doctor or by a nurse. The mothers reported three key hygienic practices in 54% of deliveries: attendants washing their hands with soap and boiling cord-tie and blade for cutting the cord. Forty-four percent of the 6,785 infants were bathed immediately after delivery, and 42% were given colostrum as their first food. The results suggest that maternal and newborn-care remains a cause of concern in rural Bangladesh. Short-term policies to promote healthy behaviour in the home are needed, in addition to the long-term goal of skilled birth attendance.

RESUMO

To evaluate immunocompetence in commercially raised chickens, we immunophenotyped Dekalb Delta and H&N White Leghorn (WLH) hybrids, 20 chickens in each of 3 age groups (9 wk [juvenile], 25 wk [young adult], and 79 or 80 wk [adult]), for circulating CD3+, CD4+, CD8+, TCR1+, TCR2+, and TCR3+ lymphocytes. The proportion of CD3+ T cells, including CD4+ and CD8+ subsets, was increased in the hybrids as compared with published values for laboratory-raised outbred WLH chickens. The proportion of the TCR2+ (Vbeta1) T cell subpopulation was also increased. An age-related decrease in the proportion of TCR1+ (gammasigma) T cells was noted in both hybrids. Further, a remarkably low CD4:CD8 ratio was evident in all age groups of both hybrids, indicating decreased immunocompetence. Overall, these experiments provide age-related proportions of various peripheral-blood T lymphocyte subpopulations in commercially raised Dekalb Delta and H&N chickens that diverge from the proportions in laboratory-raised outbred WLH chickens and suggest reduced immunocompetence. Such a decline in immunocompetence, including humoral immune capacity, could be attributed to genetic selection for production traits, environmental factors associated with commercial operations, and intense immunization.

RESUMO

Proteinuria helps to establish the diagnosis of most renal diseases and also to predict the outcome of such diseases. Proteinuria is biochemically represented by measuring the protein concentration in timed collection of 24 hour urine. But, 24-hour timed urine collection is time consuming, cumbersome and often unreliable due to collection errors and also results in undue delay on diagnostic process. An alternate approach avoiding arduous and inaccurate timed urine collection can be the measurement of protein creatinine ratio in spot morning urine. This study was aimed to evaluate whether the spot morning urine protein creatinine ratio can be a reliable alternative to 24-hour urinary total protein (UTP) estimation. The study was carried out in the department of Biochemistry, Bangabandhu Sheikh Mujib Medical University, Dhaka on 50 (fifty) non-diabetic Chronic Renal Disease (CRD) patients with an age ranging from 18 -70 years. The study subjects were grouped into mild, moderate and severe CRD on the basis of GFR. Urinary protein and creatinine concentrations were measured in spot morning urine samples and their ratios were calculated. Urinary protein measured in 24-hour timed collected urine samples gave the 24-hour UTP excretion rate. In our study, spot morning urine protein creatinine ratio significantly correlated with 24-hour UTP excretion rate in all CRD patients. Severe CRD patients gave significant positive correlation (p<0.05), whereas mild and moderate CRD patients gave very highly significant positive correlation (p<0.001). Therefore, it may be suggested that protein creatinine ratio in spot morning urine can be accepted as a reliable and alternative to 24-hour UTP excretion rate in non-diabetic chronic renal disease patients. This simple and inexpensive procedure will thus simplify the way of establishing the severity of renal disease along with its prognosis.
