Different cutaneous and mucous membrane manifestations of chronic arsenicosis, a study of Chittagong, Bangladesh

Background: Chronic arsenicosis is a serious health problem in Bangladesh now due to the intake of arsenic-contaminated groundwater above the safe level of 0.05 mg/L by shallow tube well, throughout the country. About 25 million people in Bangladesh are at risk of chronic arsenic toxicity. Arsenic toxicity is also an alarming situation in many countries of the world. Hence, the study on the health hazard of arsenic contamination, its prevalence, presentation, complication, and management is an important one. Aim: The purpose of this study is to evaluate different cutaneous and mucous membrane manifestations of chronic arsenicosis. Method: The study descriptive was conducted in the Department of Dermatology and Venereology in Chittagong Medical College Hospital. A total of 105 patients of clinically diagnosed chronic arsenicosis were selected for the study. Clinical manifestations of chronic arsenicosis patients were analyzed for different mucocutaneous findings. Result: Evaluation and analysis of findings showed chronic arsenicosis patients had characteristic features of melanosis or leukomelanosis (raindrop pigmentation) in 100% of patients. Another characteristic finding of palmoplantar punctate hyperkeratosis was found in 69.5% of patients of chronic arsenicosis. Other mucocutaneous findings of chronic arsenicosis were cutaneous malignancy such as basal cell carcinoma, squamous cell carcinoma, and Bowen’s disease. Other cutaneous and systemic diseases were also observed in patients of chronic arsenicosis. Conclusion: Characteristic mucocutaneous findings of chronic arsenicosis were melanosis, leukomelanosis (raindrop pigmentation), palmoplantar punctate hyperkeratosis, and cutaneous malignancy. As chronic arsenicosis is a serious health problem in our country, it demands more research on chronic arsenicosis. Further reading click here

Serum Erythropoietin Level in Chronic Kidney Disease Patients with Anemia: A Baseline Study at Chittagong Medical College, Chittagong, Bangladesh

Image
Abstract: Chronic kidney disease (CKD) is a serious condition associated with premature mortality, decreased quality of life, and increased health-care expenditures. A failure to produce sufficient Erythropoietin (EPO) accounts for the moderate to severe anemia observed in chronic kidney disease. Decreased EPO production is attributed to the destruction of renal production sites. A cross-sectional descriptive study was designed for the determination of erythropoietin levels in chronic kidney disease patients with anemia. At the same time measurement of serum iron and serum ferritin to establish anemia. The serum concentration of erythropoietin was the parameter taken to evaluate the kidney status. This study was carried out in the Nephrology ward, Chittagong Medical College Hospital (CMCH), Chittagong, Bangladesh during the period of January 2012 to December 2012. Total Sixty Patients having hemoglobin level < 11 gm/dl and serum creatinine > 3 mg/dl taken as a case of chronic ki

Outcome of Surgical Management in Compound Depressed Skull Fractures With Primary Bone Fragment Replacement

Image
Abstract: Head injury is one of the most common causes of death worldwide & compound depressed skull fracture is an important cause of mortality & morbidity in this regard. Gradual urbanization and industrialization along with poor traffic control, use of over dated malfunctioning vehicles, poor and unplanned road traffic systems and overall lack of awareness of the people regarding traffic systems increase RTA (Road Traffic Accident) along with head injury. Besides this, assaults fall from height, sports injuries, birth trauma, etc are also important causes of head injury in our country. Health professionals are always facing these patients with a head injury in their everyday practice. Modern imaging facilities support early treatment and lead the outcome of compound depressed fractures of the skull towards zero mortality. But in developing countries like us due to lack of good health infrastructure & neurosurgical service along with the scarcity of neurosurgeons, commun
