Socio-demographic factors affecting knowledge level of Tuberculosis patients in Rajshahi City, Bangladesh.

Background: The Tuberculosis (TB) control program in Bangladesh is still unsatisfactory due to insufficient knowledge and stigma about TB. Patients with low knowledge may be at higher risk of experiencing delays in diagnosis and appropriate treatment.

Objectives: The aims of this study were to identify the knowledge levels of TB and investigate the factors associated with knowledge level among the TB patients in Bangladesh.

Impact monitoring of the national scale up of zinc treatment for childhood diarrhea in Bangladesh: repeat ecologic surveys.

Background: Zinc treatment of childhood diarrhea has the potential to save 400,000 under-five lives per year in lesser developed countries. In 2004 the World Health Organization (WHO)/UNICEF revised their clinical management of childhood diarrhea guidelines to include zinc. The aim of this study was to monitor the impact of the first national campaign to scale up zinc treatment of childhood diarrhea in Bangladesh.

The prevalence of Entamoeba histolytica in lactating women and in their infants in Bangladesh.

Entamoeba histolytica was studied in 33 lactating women and their infants in a periurban village in Bangladesh. Infant-mother pairs were followed for a period of 10-15 months: 67% of mothers excreted E. histolytica during the observation period, the majority for 3 months or more.

Scabies in urban Bangladesh.

As a part of a larger project on hygiene education and diarrhoeal diseases we followed 766 children less than 6 years of age from October 1984 to September 1985 in Dhaka, Bangladesh. The aims were to estimate the annual risk of infestation with scabies in children, to describe its involvement of other family members, and to determine some of the familial and individual risk factors for apparent infestation by scabies. During this period 589 (77%) children appeared to have been infected with scabies, and 125 (16%) children were infested for more than 6 months.

Giardia lamblia infections in a cohort of Bangladeshi mothers and infants followed for one year.

Giardia lamblia infection in an endemic area was investigated by following a cohort of 33 lactating mothers and their infants in a semiurban community of Bangladesh for one year. Eighty-two percent of mothers and 42% of infants excreted Giardia at least once during the study period. Infants became infected as early as 3 months of age, and 86% of the infected infants had diarrhea, suggesting that the first exposure to the parasite results in disease.
