Introduction. Use of lead acid battery (LAB) in Bangladesh has risen with sharp rise of motor vehicles. As result, manufacture of LAB is increasing. Most of the lead used by these industries comes from recycling of LAB. Workers in LAB industry are at risk of exposure lead and thus development of lead toxicity. Objective. The objective of this study was to measure the blood lead concentration and to assess the magnitude of health problems attributable to lead toxicity among the LAB manufacturing workers. Methods. A cross-sectional study was conducted among the workers of LAB manufacturing industries located in Dhaka city. Result. Mean blood lead level (BLL) among the workers was found to be high. They were found to be suffering from a number of illnesses attributable to lead toxicity. The common illnesses were frequent headache, numbness of the limbs, colic pain, nausea, tremor, and lead line on the gum. High BLL was also found to be related to hypertension and anemia of the workers. Conclusion. High BLL and illnesses attributable to lead toxicity were prevalent amongst workers of the LAB manufacturing industries, and this requires attention especially in terms of occupational hygiene and safety.

Abstract:Objectives: To determine the oral hygiene practices, periodontal status and bad mouth breath (BMB) among the children age between 5 to 15 years. Study participants and methods: This was a cross sectional descriptive study conducted at at four-selected primary school at Fultola and Juri Upazilla of Moulovi Bazar District. Total 250 children aged 5-15 years, were interviewed on oral hygiene practices and BMB using structured questionnaire and a checklist. Oral hygiene and periodontal status were assessed by using disposable dental explorer and a dental mirror. Results: Oral hygiene practice were ; where (66.8%) non tooth brush and tooth brush users were (33.2%). The prevalence of dental caries plaque, gingival bleeding and BMB on probing was (69.6%), (91.6%), (66.8 %) and (64%) respectively. Conclusion: Bad mouth breath is a cause of concern among children associated significant factors were gum bleeding. Research involving clinical diagnosis of bad mouth breath and intervention through oral health promotion and periodontal therapy are recommended. Clinical relevance: This study provides baseline information on oral health status and bad mouth breath which necessitates in the future need for objective assessment, diagnosis and management of bad mouth breath for enhanced social and professional interaction without embarrassments.

This cross-sectional study was carried out to assess and compare Ankle Brachial Systolic Pressure Index (ABSPI) amongst 120 arsenic exposed and 120 non-exposed populations of Samta village in Bangladesh. Abnormal ABSPI was more prevalent in arsenic exposed (13.3%) than in non-exposed (2.5%) group. The prevalence of abnormal ABSPI for respondents when adjusted for age, sex, BMI, blood pressure status and diabetic status, the prevalence remain significantly different. The findings suggest that those exposed to arsenic have increased chance of having abnormal ABSP and hence increased chance of peripheral arterial disease in Bangladesh.

Halitosis is known as bad breath that emanates from the oral cavity either intra-oral and/or extra-oral origins with different nomenclature such as oral malodor, foetor ex ore, bad breath, foul smell or in Bengali durgondha. Fifty percent of people worldwide view themselves as having halitosis, with (85.0-90.0%) of the etiology being intra-oral. Oral causes include basically tongue coating and other various causes like tooth decay, periodontitis, chronic gingivitis, oral infections, pericoronitis, calculus deposition, oral mucosal ulceration (bacterial and/or fungal), impacted food particles, orthodontic problems and poor oral hygiene practice. These sorts of foul smell of the oral cavity most often results from the bacterial degradation of oral organic substrates as volatile sulfur compounds (VSC). The source of halitosis may be related both to oral and systemic condition, but majority of cases are commonly related to oral factors. So far knowledge goes there have been a few studies evaluating the prevalence of bad mouth breath (BMB) in general population. The aim of this reviews are the classification of halitosis, assessment, diagnosis, intra-oral and systemic contributing factors, treatment, management and clinical application.
