Abstract

Background

In Gondar University Teaching Hospital standardized tuberculosis prevention and control programme, incorporating Directly Observed Treatment, Short Course (DOTS) started in 2000. According to the proposal of World Health Organization (WHO), treatment outcome is an important indicator of tuberculosis control programs. This study investigated the outcome of tuberculosis treatment at Gondar University Teaching Hospital in Northwest Ethiopia.

Methods

We analyzed the records of 4000 tuberculosis patients registered at Gondar University Teaching Hospital from September 2003 to May 2008. Treatment outcome and tuberculosis type were categorized according to the national tuberculosis control program guideline. Multivariate analysis using logistic regression model was used to analyse the association between treatment outcome and potential predictor variables.

Results

From the total of 4000 patients, tuberculosis type was categorized as extrapulmonary in 1133 (28.3%), smear negative pulmonary tuberculosis in 2196 (54.9%) and smear positive pulmonary tuberculosis in 671 (16.8%) cases. Of all patients, treatment outcome was classified as successfully treated in 1181(29.5%), defaulted in 730 (18.3%), died in 403 (10.1%), treatment failed in six (0.2%) and transferred out in 1680 (42.0%) patients. Males had the trend to be more likely to experience death or default than females, and the elderly were more likely to die than younger. The proportion of default rate was increased across the years from 97(9.2%) to 228(42.9%). Being female, age group 15-24 years, smear positive pulmonary tuberculosis and being urban resident were associated with higher treatment success rate.

Conclusion

The treatment success rate of tuberculosis patients was unsatisfactorily low (29.5%). A high proportion of patients died (10.1%) or defaulted (18.3%), which is a serious public health concern that needs to be addressed urgently.

BackgroundAs is common in developing countries, in Ethiopia young people with disabilities (YPWD) are more likely than the general population to be illiterate, unemployed and impoverished. They often lack equal access to information and education for reasons ranging from barriers regarding physical access to services to varied special learning needs. Very little is known about knowledge, attitude and practice (KAP) of YPWD regarding sexual and reproductive health (SRH) related issues. We, therefore, aimed to assess the KAP of 426 YPWD in Addis Ababa, Ethiopia.MethodsA cross-sectional survey was conducted in 2012. Data were collected by trained interviewers using a structured questionnaire covering socio-demographic information, as well as information on KAP regarding SRH.ResultsOnly 64.6 % of YPWD were aware of SRH services. Radio and TV were mentioned as the main sources of information by 62.2 % of the participants. 77.9 % had never had a discussion about SRH topics with their parents. Even though 96.7 % of the respondents had heard about HIV, 88 % had poor knowledge about ways of preventing HIV. Perception of the risk of getting infected with HIV was found to be generally low in YPWD; only 21.6 % believed that they were at risk of acquiring HIV.ConclusionsOur study, in general, demonstrated that there is a lack of comprehensive knowledge, appropriate practice and favorable attitude of YPWD regarding different SRH-related issues. Our findings thus clearly indicate the need for strategies and programs to raise SRH-related awareness and to help YPWD to develop the appropriate skills and attitudes needed for a healthy reproductive life.

BackgroundDiarrheal diseases are the major causes of morbidity and mortality in developing world. Understanding the etiologic agents of diarrheal diseases and their association with socio-demographic characteristics of patients would help to design better preventive measures. Thus, this study was aimed to determine the prevalence of intestinal parasites and enteropathogenic bacteria in diarrheic patients.MethodsA cross-sectional study involving 384 consecutive diarrheal patients who visited Gondar teaching hospital, Gondar, Ethiopia from October 2006 to March 2007 was conducted. Stool specimens were collected and examined for intestinal parasites and enteropathogenic bacteria following standard parasitological and microbiological procedures.ResultsIntestinal parasites were diagnosed in 36.5% of the patients. The most frequently encountered protozoan parasite was Entamoeba histolytica/dispar (7.3%) followed by Giardia lamblia (5.0%), Cryptosporidium parvum (1.8%) and Isospora belli (1.3%). The dominant helminthic parasite identified was Ascaris lumbricoides (5.5%) followed by Strongyloides stercoralis and Schistosoma mansoni (3.1% each), hookworm infection (1.8%), and Hymenolepis species (1.3%). Multiple infections of intestinal parasites were also observed in 6.3% of the patients. Among the enteropathogenic bacteria Shigella and Salmonella species were isolated from 15.6% and 1.6%, respectively, of the patients. Escherichia coli O57:H7 was not found in any of the stool samples tested. Eighty eight percent and 83.3% of the Shigella and Salmonella isolates were resistant to one or more commonly used antibiotics, respectively.Intestinal parasitosis was higher in patients who live in rural area, in patients who were washing their hands after visiting toilet either irregularly with soap and without soap or not at all, in patients who used well and spring water for household consumption, and in patients who had nausea (P < 0.05). Statistically significant associations were also observed between Shigella infections and patients who were using well and spring water for household consumption, and patients who had dysentery and mucoid stool (P < 0.05).ConclusionsThe high prevalence of intestinal parasites and Shigella species in diarrheic patients calls for institution of appropriate public health intervention measures to reduce morbidity and mortality associated with these diseases. The rational use of antibiotics should also be practiced.

BackgroundVitamin A deficiency (VAD) is known to be a major public health problem among women of reproductive age in South East Asia and Africa. In Ethiopia, there are no studies conducted on serum vitamin A status of HIV-infected pregnant women. Therefore, the present study was aimed at determining the level of serum vitamin A and VAD among pregnant women with and without HIV infection in tropical settings of Northwest Ethiopia.MethodsIn this cross-sectional study, blood samples were collected from 423 pregnant women and from 55 healthy volunteers who visited the University of Gondar Hospital. Serum concentration of vitamin A was measured by high performance liquid chromatography.ResultsAfter controlling for total serum protein, albumin and demographic variables, the mean ± SD serum vitamin A in HIV seropositive pregnant women (0.96 ± 0.42 μmol/L) was significantly lower than that in pregnant women without HIV infection (1.10 ± 0.45 μmol/L, P < 0.05). Likewise, the level of serum vitamin A in HIV seropositive non-pregnant women (0.74 ± 0.39) was significantly lower than that in HIV negative non-pregnant women (1.18 ± 0.59 μmol/L, P < 0.004). VAD (serum retinol < 0.7 μmol/L) was observed in 18.4% and 17.7% of HIV infected and uninfected pregnant women, respectively. Forty six percent of non-pregnant women with HIV infection had VAD while only 28% controls were deficient for vitamin A (P = 0.002).ConclusionThe present study shows that VAD is a major public health problem among pregnant women in the tropical settings of Northwest Ethiopia. Considering the possible implications of VAD during pregnancy, we recommend multivitamin (which has a lower level of vitamin A) supplementation in the care and management of pregnant women with or without HIV infection.
