Patch test for the detection of contact allergens.

Patch Test was done in 340 suspected allergic contact dermatitis patients having different ages of both sexes during the period of January 2000 to December 2003 in the department of Dermatology and Venerology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka. Of these 340 cases 145 (42.65%) were male and 195 (57.35%) were female. Among these 340 cases, 250 (73.53%) cases were tested with international standard series allergen (ISS) and 90 (26.47%) cases with cosmetic series allergen (CSS), of which patch test was positive in 125 (50%) cases and 65 (72.22%) cases respectively. The 125 positive cases with ISS consisted of 56% male and 44% female. In 65 CSS positive cases 90.77% were female and 9.23% were male. Highest incidence of positive patch test was found in 61.54% cases in the age group of 30-39 years in ISS and 71.43% cases in the age group of 20-29 yrs in CSS. In ISS--Potassium Dichromate (19.2%), Fragrance mix (17.6%), Nickel Sulphate (15.2%) and PPD (11.2%) were found to be the common allergen and in CSS--Octyl Gallate (27.69%), Getrimide (18.92%), Balsum of Peru (15.38%), Thiomersal (12.31%) were found to be the common allergens.

Rapid assessment of the prevalence of lower limb clinical rickets in Bangladesh.

This study attempted to measure the prevalence of lower limb clinical rickets using a rapid assessment methodology in Cox's Bazaar, a coastal district of Bangladesh. The study populations were drawn from 28 random villages representing all seven 'thanas' (subdistricts) of the district. Data were collected on 25,891 children and young people aged 1-20 years in two phases. In the first phase, 30 trained, local, non-medical people listed 490 children suffering from visible signs of any physical disability. To achieve this, they demonstrated a multicolored poster showing the features of lower limb clinical rickets to key informants in the villages. In the second phase, two teams of medically trained people (physicians), each with one male and one female, validated the above cases for rickets. They verified and validated 278 cases in five thanas. Due to inclement weather and floods, they could not visit the other two thanas. Based on these data, the adjusted prevalence rates for lower limb clinical rickets were calculated to be 931 per 100,000 population (95% confidence intervals 795-1067). The prevalence was highest (1215) in children aged 1-4 years and lowest (498) amongst 17-20 year olds. Females had lower prevalence than males. Based on the study experience, a quick investigation using a similar methodology was performed in five other districts (Sunamganj, Noakhali, Bhola, Jessore and Gaibandha), and clinical signs of lower limb rickets were found in Sunamganj and Jessore. It thus indicates that rickets may be endemic, not only in Cox's Bazaar but also in some other parts of Bangladesh. The methodology used for this study was found to be rapid, simple, replicable and inexpensive.

Updating of hereditary haemoglobin disorders.

Hereditary haemoglobin disorders (E-beta Thalassaemia & Thalassaemia) are inherited as recessive disorders so that the heterozygote subjects are generally healthy. They commonly present with progressive pallor, thalassaemic facies, splenohepatomegaly & growth retardation. Diagnosis of carriers & patients are usually confirmed by haemoglobin electrophoresis. Transfusion-chelation therapy is usually employed for their treatment. Allogenic bone marrow transplantation is the only definite cure. Gene therapy remains to be the major challenging goal of future curative therapy. During the last 10 years wit medical advances, the number of pregnancies in thalassaemia is increasing. Normal pregnancy can be maintained with regular packed blood cells transfusion given carefully. In Bangladesh, HHD can be prevented by I. carrier identification and marriage counseling, II. passing and enforcing laws against marriage between two carriers, III. introducing thalassaemia in school curriculum and IV. creating public awareness.

Change in health knowledge of Bangladeshi children: five years experience.

This article explores the improvement in the level of health knowledge of Bangladeshi children over a five year period 1993-1998. Data were generated from two nationally representative sample surveys covering respectively 2520 and 3360 children aged 11-12 y. Six health knowledge items, relevant to life in Bangladesh, were considered. Analyses revealed a significant improvement in the knowledge over the period. However, significant socio-economic variations also persisted in the performance. Rural children improved much faster compared to their urban counterparts. In both the surveys, children's performance varied significantly by items. To equip children with necessary health knowledge this study suggested strengthening health education at primary level in Bangladesh.

Human rights and religious backlash: the experience of a Bangladeshi NGO.

As part of a human rights education campaign, the Bangladesh Rural Advancement Committee fixed 700,000 posters throughout Bangladesh. This met with opposition from the religious organizations. This paper investigates the nature and cause of the backlash and sets out strategies for how development organizations can achieve their objectives in the face of opposition. The opposition was found to be in response to interpretations of the posters based on the Holy Koran and Islamic practices, and a perceived intrusion into the professional territory of religious organizations, which affected the socioeconomic interests of these organizations' representatives. It was therefore concluded that development organizations should pre-empt such opposition by spelling out their objectives to potential critics, and formulating programs that do not provide scope for opponents to undermine their development activities.

Patterns of vaccination acceptance.

Immunization is one of the major public health interventions to prevent childhood morbidity and death. The Expanded Programme on Immunization has gathered momentum worldwide since 1974. The range of vaccines in the programme is being expanded in the years to come. All across the globe, a high level of vaccination coverage has been reached and now needs to be sustained. In part, the coverage has been made possible by the broad acceptance of vaccinations, although there are variations resulting in different configurations of fully, partially and non-immunized children. Using the results of studies carried out by the Social Science and Immunization Project in Bangladesh, Ethiopia, India, Malawi, the Netherlands and the Philippines, this article describes and discusses patterns of vaccination acceptance and non-acceptance. It shows how context affects acceptance of vaccinations, and analyses the underlying reasons behind refusal and resistance. The article also develops conceptual tools for the analysis of acceptance and non-acceptance and discusses explanatory theoretical perspectives.

Quality of vaccination services and social demand for vaccinations in Africa and Asia.

For immunization to be effective in the long run as a major global disease control intervention it is important to provide good quality vaccination services. Studies carried out in three countries in Asia (Bangladesh, India, and the Philippines) and two countries in Africa (Ethiopia and Malawi), and reported on in this article, document the fact that parents are willing to invest considerable effort in having their children vaccinated; however, there are a number of serious shortcomings in the quality of the routine vaccination services and strains are apparent at the interface between the vaccination providers and the users. These shortcomings are detracting from the sustainability of routine vaccination programmes and are promoting the growth of pools of nonimmunized and partially immunized children. To safeguard the continued operation and to enhance the coverage of routine vaccination programmes it is crucial that these difficulties be addressed.

Health beliefs and folk models of diabetes in British Bangladeshis: a qualitative study.

OBJECTIVE: To explore the experience of diabetes in British Bangladeshis, since successful management of diabetes requires attention not just to observable behaviour but to the underlying attitudes and belief systems which drive that behaviour. DESIGN: Qualitative study of subjects' experience of diabetes using narratives, semi-structured interviews, focus groups, and pile sorting exercises. A new qualitative method, the structured vignette, was developed for validating researchers' understanding of primary level culture. SUBJECTS: 40 British Bangladeshi patients with diabetes, and 10 non-Bangladeshi controls, recruited from primary care. RESULT: Several constructs were detected in relation to body image, cause and nature of diabetes, food classification, and knowledge of complications. In some areas, the similarities between Bangladeshi and non-Bangladeshi subjects were as striking as their differences. There was little evidence of a fatalistic or deterministic attitude to prognosis, and most informants seemed highly motivated to alter their diet and comply with treatment. Structural and material barriers to behaviour change were at least as important as "cultural" ones. CONCLUSION: Bangladeshi culture is neither seamless nor static, but some widely held beliefs and behaviours have been identified. Some of these have a potentially beneficial effect on health and should be used as the starting point for culturally sensitive diabetes education.

Chronic energy deficiency in women from rural Bangladesh: some socioeconomic determinants.

This paper explores a number of socioeconomic factors thought to explain the wide prevalence of undernutrition among rural Bangladeshi women. The 1992 baseline survey data of the BRAC-ICDDR,B Joint Research Project at Matlab were used. Anthropometry was performed on a random sub-sample of 1462 currently married, non-pregnant women between 15 and 49 years of age. Women's nutritional status was defined in terms of Body Mass Index (BMI = wt in kg/ht in m2). Compared with women from better-off households, the mean weight (41.2 vs 43.0 kg; p < 0.0001), mid-upper arm circumference (MUAC) (22.1 vs 22.7; p < 0.0001), and BMI (18.5 vs 19.1; p < 0.0001) of poor women were consistently lower. However, no significant difference in mean height was found between the two groups. The results showed that women aged more than 35 years are twice as likely to have a BMI < 18.5 compared with younger women. Both years of schooling received and socioeconomic status are found to be important predictors of women's BMI. Women who have received one or more years of formal education are nearly half as likely to suffer chronic energy deficiency (BMI < 18.5) than women with no schooling. Again, better-off women are found to be 0.77 times less likely to have chronic energy deficiency than women from poor households. The implications of these findings in improving the nutritional status of rural Bangladeshi women are discussed.

Training and retaining Shasthyo Shebika: reasons for turnover of community health workers in Bangladesh.

Shasthyo Shebikas (SS) are community health workers forming the core of BRAC's Essential Health Care (EHC) programme. The SS dropout was 44 percent for study area and 32 percent for EHC programme. The SS discontinued their work due to lack of time, lack of "profit", and family's disapproval. The effects of the dropouts were decreased achievement of targets, and a loss of money in the amount of $24 (U.S.) per dropout SS for their training and supervision. The SS retention may increase if EHC strictly adheres to its existing guidelines when selecting trainees, and if it highlights during SS training that SS; s first and foremost role will be as that of a volunteer and then of a salesperson.

Control of tuberculosis by community health workers in Bangladesh.

BACKGROUND: Tuberculosis remains a major public-health problem in Bangladesh, despite national efforts to improve case identification and treatment compliance. In 1984, BRAC (formerly the Bangladesh Rural Advancement Committee), a national, non-governmental organisation, began an experimental tuberculosis-control programme in one thana (subdistrict). Community health workers screened villagers for chronic cough and collected sputum samples for acid-fast bacillus (AFB) microscopy (phase one). Positive patients received 12 months of directly observed therapy. Phase two (1992-94) included another nine thanas and, in phase three (1995), eight more thanas were included. From 1995, the treatment was an 8-month oral regimen. METHODS: In 1995-96, we analysed all programme data from 1992 to 1995. First we analysed phases two (12-month therapy) and three (8-month therapy) separately for proportion cured, died, treatment, failed, defaulted, migrated, and referred. Second, we did a cross-sectional survey of tuberculosis cases in more than 9000 randomly selected households in two phase-two thanas and one non-programme thana, and analysed the follow-up of all patients treated in the programme thanas. FINDINGS: In the phase-two analysis, 3497 (90%) of 3886 cases identified had accepted 12-month treatment. In phase three, all of 1741 identified cases accepted the 8-month regimen. 2833 (81.0%) and 1496 (85.9%) in phases two and three, respectively, were cured; 336 (9.6%) and 133 (7.6%) died. The relapse rate 2 or more years after treatment was discontinued was higher than the early relapse rate. The drop-out rate was 3.1%. In the cross-sectional survey, the prevalence of tuberculosis in the two programme thanas was half of that in the comparison thana, where only government services were available (0.07 vs 0.15 per 100 [corrected]). INTERPRETATION: The BRAC tuberculosis-control programme has successfully achieved high rates of case detection and treatment compliance, with a cure rate of at least 85% and a drop-out rate of 3.1%. The prevalence survey suggested that at least half of all existing cases had been detected by the programme.

The status of ORT (oral rehydration therapy) in Bangladesh: how widely is it used?

During 1980-1990 BRAC, a Bangladeshi non-governmental organization, taught over 12 million mothers how to prepare oral rehydration therapy (ORT) at home with lobon (common salt) and gur (unrefined brown sugar). This was followed by a strong promotion and distribution of prepackaged ORS by various agencies including the government. In 1993 we assessed knowledge of ORT preparation, its local availability and its use for the management of diarrhoea. Over 9000 households in 90 villages were revisited; 306 government outreach health workers, 296 drug sellers, and 237 village doctors were interviewed; 152 government facilities and 495 pharmacies/shops were visited. ORT prepared by mothers in a sub-sample of the households was analyzed for chloride content and interviewers collected information on use of ORT for diarrhoeal episodes occurring in the preceding two weeks. The data quality was assessed through a resurvey of sample respondents within two weeks of the first interview. Over 70% of the mothers could prepare a chemically 'safe and effective' ORS. A significant proportion of these mothers were very young at the time of the mass campaigns using house to house teaching, implying an intergenerational transfer of the knowledge on ORT. ORT was found to be used in 60% of all diarrhoeal episodes, but the rate varied with the type of diarrhoea, being highest for daeria (severe watery diarrhoea) and lowest for amasha (dysentery). Drug sellers and village doctors now recommend ORT much more frequently than before. Members of the medical profession (qualified and unqualified) still lag behind in prescribing the use of ORT. The availability of pre-packaged ORS in rural pharmacies has improved enormously. There is convincing evidence that the widescale promotion in the past of ORS for dehydration in diarrhoea has led to this marked improvement today. Nevertheless the use of rice-based ORS, culturally appropriate messages and the promotion of ORS with food offer opportunities to further improve the utilization of ORT.

Health knowledge of children in Bangladesh: an exploratory study.

This article explores the relationship between selected socio-economic factors and health knowledge of children in Bangladesh. Data was generated from a representative sample survey of 2520 children aged 11-12 y and resident throughout the country. A total of six health knowledge items, all of which are very relevant to Bangladesh, were assessed in this study. Both bivariate and multivariate analysis were used for this purpose. Analysis revealed that the urban/rural residence of the child, the length of the child's schooling in years, the parental level of education and the economic status of the household was associated with the level of health knowledge of the children. To achieve the required improvement in health knowledge of Bangladeshi children this study concluded that adequate schooling of all children must be ensured by removing social barriers to this. Greater educational investment as well as quality education related to everyday life should be provided in rural areas.
