ABSTRACT
Backgrounds: About 120 million people around the world are overexposed to lead which is neurotoxic and 99 percent of the most severely affected children are in the developing world including Bangladesh. Methods and Materials: The present cross-sectional ecological study was carried out to explore the impact of lead poisoning on the intelligence level among 84 primary school children of a school of Bangladesh, aged between 8 and 14 years from September 2010 through January 2011. The research instrument was an interviewer questionnaire, questionnaire for IQ test and assessment of blood lead level (inductively-coupled plasma mass spectrometry with collision/reaction cells) of the study subjects after obtaining permission from their parents and the school authority. Results: Data were cross-checked and frequency distribution and association using chi-square test was accomplished. Background information depicted majority (69.1%) of the children aged10-11 years (mean = 10.25 ±1.177 yrs), female (51.2%), parents having primary level of education or below (73.8% in case of father and 77.4% in mother) and from lower socioeconomics (78.6% earned BDT 10,000 or below per month). Among all, majority (56%) were found to be moron, 27.4% in borderline, while 8.3% were imbecile with the same proportion with normal level. By their blood lead level. Majority (70.2%) had blood lead level up to 10 microgram/dl and the rest (29.8%) had more than 10 microgram/ dl. Though no statistically significant association was found between IQ level of the children and their blood lead level (p>0.05), the health problems found among the respondents as abdominal pain (53.57%), impatience (14.29%), nausea (10.71%) and all other problems (loss of concentration to study, ear problem, anorexia and loss of weight) amounting for 21.43% are suggestive of chronic lead poisoning. Conclusion: Further studies in large scale with larger samples including comparative studies of inter-industrial areas have been strongly recommended.
ABSTRACT
A 14 year-old Bangladeshi girl presented with high fever, painful swellings in the neck, anorexia, weight loss and night sweating. On examination she had multiple enlarged and tender cervical lymph nodes. Other systems were normal. Laboratory investigations for sepsis and autoimmune diseases were negative. Initial fine needle aspiration and cytology of affected lymph node was suggestive of tubercular lymphdenitis. But she did not respond to anti-tubercular treatment. Kikuchi-Fujimoto disease was diagnosed from the histopathological appearance of excised lymph node. She completely recovered with symptomatic treatment. Kikuchi-Fujimoto disease, also called Kikuchi's disease or histiocytic necrotizing lymphadenitis is a rare, benign but enigmatic disease of unknown aetiology. The disease is self-limited and has an excellent prognosis. Its recognition is crucial because it can be mistaken for systemic lupus erythematosus, malignant lymphoma, tubercular lymphadenitis or even, for metastatic adenocarcinoma. Clinicians' and pathologists' awareness of this disease may help prevent misdiagnosis and inappropriate treatment.
ABSTRACT
A total of 479 children aged 6-60 months (male/female, 240/239) were studies during 1991 to 1992. Weight for age, height for age (mean +/- SD) were 72 +/- 11%, 90 +/- 7 and 87 +/- 10% of NCHS median respectively. According to Gomez classification, 96% of children had varying degrees of protein energy malnutrition (PEM) (28.4% mild, 58.2% moderate and 9.2% severe). According to Waterlow classification 84% were stunted(36% mild, 33% moderate and 15% severe) and 67% were wasted (47% mild, 18% moderate and 2% severe). Of all children 368 (77%) received BCG and 439 (82%) received partial or full dose of DPT and Polio vaccines. Among children aged 13-60 months 75% received Measles vaccine. Weaning food was started at (mean +/- SD) 8 +/- 4 months. Low household income, parental illiteracy, small family size (< or = 6), early or late weaning and absence of BCG vaccination were significantly associated with severe PEM. Timely weaning, education and promotion of essential vaccination may reduce childhood malnutrition especially severe PEM.
