Camel herd health and productivity in Eastern Ethiopia selected semi-nomadic households

Cette étude a été réalisée sur des dromadaires élevés en conditions pastorales d'octobre 1997 à septembre 1998. La trypanosomose a été une des maladies les plus importantes identifiée avec une prévalence maximale de 20,6 p. 100 et minimale de 5,4 p. 100 sur la période d'échantillonnage. Le taux de prévalence de la gale sarcoptique a varié de 21,7 p. 100 pendant la saison pluvieuse à 4,7 p. 100 pendant la saison sèche. Le taux de prévalence d'oeufs de strongles le plus élevé a été de 85,7 p. 100 pendant la saison pluvieuse et le plus faible de 61,5 p. 100 en saison sèche. Le plus grand nombre d'oeufs par gramme enregistré a été 1 036,1 ± 0,6 et le plus faible 358,8 ± 0,6. La production de lait a été significativement (p < 0,01) plus élevée pendant la saison des pluies (3,1 1) que pendant la saison sèche (1,5 1). La production de lait a également été significativement (p < 0,01) plus élevée chez les chamelles ayant mis bas 1-4 fois (3 1) que chez les femelles ayant mis bas 5 fois ou plus (1,6 1). Les femelles immatures (1 -4 ans) ont eu un gain de poids quotidien significativement (p < 0,01) plus élevé (59,4 g) que les mâles au même âge (33,2 g). Par ailleurs, le gain de poids quotidien des dromadaires de 1-2 ans (63,1 g) a été significativement (p < 0,01) plus élevé que celui des 3-4 ans (29,5 g). De même le gain de poids quotidien a été significativement (p < 0,05) plus élevé pendant la saison des pluies (50,7 g) que pendant la saison sèche (41,9 g). La plupart des montes et des mises bas ont eu lieu pendant la saison des pluies. Le taux annuel de mises bas du troupeau a été de 42,7 p. 100. Les taux de commercialisation annuels et de croissance ont été respectivement de 4,74 et 8,9 p. 100. Le taux de mortalité des chamelons de moins d'un an a été plus élevé que celui des animaux immatures et adultes. (Résumé d'auteur

Incidence and Predictors of Tuberculosis Among Adult PLWHA at Public Health Facilities of Hawassa City

Tuberculosis (TB) is the most frequently diagnosed opportunistic infection (OI) and disease in people living with HIV/AIDS (PLWHA), world-wide. This study aimed at determining the incidence and predictors of tuberculosis among people living with HIV.A Six year retrospective follow up study was conducted among adult PLHIV. The Cox proportional hazards model was used to identify predictors.A total of 554 patients were followed and produced 1830.3 person year of observation. One hundred sixty one new TB cases occurred during the follow up period. The overall incidence density of TB was 8.79 per 100 person-year (PY). It was high (148.71/100 PY) in the first year of enrolment. The cumulative proportion of TB free survival was 79% and 67% at the end of first and sixth years, respectively. Not having formal education(AHR=2.68, 95%CI: 1.41, 5.11 ), base line WHO clinical stage IV (AHR = 3.22, 95% CI=1.91-5.41), CD4 count <50 cell/ul (AHR=2.41, 95%CI=1.31, 4.42), Being bed redden (AHR= 2.89, 95%CI=1.72, 3.78), past TB history (AHR=1.65, 95% CI = 1.06,2.39), substance use (AHR=1.46, 95% CI=1.03,2.06) and being on pre ART (AHR=1.62, 95%CI:1.03-2.54 ) were independently predicted tuberculosis occurrence. Advanced WHO clinical stage, limited functional status, past TB history, addiction and low CD4 (<50cell/ul) count at enrollment were found to be the independent predictor of tuberculosis occurrence. Therefore early initiation of treatment and intensive follow up is important

The prevalence and pattern of HPV-16 immunostaining in uterine cervical carcinomas in Ethiopian women: a pilot study

INTRODUCTION: Cancer of the cervix uteri is the second most common cancer among women worldwide. The association of human papillomavirus (HPV) infection with cervical carcinogenesis is well documented. This is a pilot study aiming to studying the prevalence and the pattern of Human Papilloma Virus Type 16 (HPV16) by immunostaining in the tissues of cervical carcinomas of Ethiopian women. METHODS: 20 specimens of uterine cervical carcinomas were studied histopathologically and immunohistochemically for HPV16. RESULTS: Histologically the specimens were classified as: Ten cases were Non Keratinized Squamous cell carcinoma (NKSCC), six cases were Keratinized Squamous Cell Carcinoma (KSCC) and four cases were Adenocarcinoma (ADC). Immunohistochemistry study showed positivity in eleven cases (55%); seven cases (35%) were non-keratinized squamous cell carcinoma; three cases (15%) were keratinized squamous cell carcinoma and one case (5%) belonged to the adenocarcinomas. CONCLUSION: This study reveals a significant detection of HPV in Ethiopian women by the use of advanced techniques such as Immunohistochemistry (IHC). The data of this study suggested that the marked expression of the HPV 16 was in the less differentiated uterine cervix carcinoma

Why do women not use skilled birth attendance service? An explorative qualitative study in north West Ethiopia

Abstract Background Having a birth attendant with midwifery skills during childbirth is an effective intervention to reduce maternal and early neonatal morbidity and mortality. Nevertheless, many women in Ethiopia still deliver a baby at home. The current study aimed at exploring and describing reasons why women do not use skilled delivery care in North West Ethiopia. Methods This descriptive explorative qualitative research was done in two districts of West Gojjam Zone in North West Ethiopia. Fourteen focus group discussions (FGDs) were conducted with pregnant women and mothers who delivered within one year. An inductive thematic analysis approach was employed to analyse the qualitative data. The data analysis adhered to reading, coding, displaying, reducing, and interpreting data analysis steps. Results Two major themes client-related factors and health system-related factors emerged. Factors that emerged within the major theme of client-related were socio-cultural factors, fear of health facility childbirth, the nature of labour, lack of antenatal care (ANC) during pregnancy, lack of health facility childbirth experience, low knowledge and poor early care-seeking behaviour. Under the major theme of health system-related factors, the sub-themes that emerged were low quality of service, lack of respectful care, and inaccessibility of health facility. Conclusions This study identified a myriad of supply-side and client-related factors as reasons given by pregnant women, for not giving birth in health institution. These factors should be redressed by considering the specific supply-side and community perspectives. The results of this study provide evidence that could help policymakers to develop strategies to address barriers identified, and improve utilisation of skilled delivery service

Surgically treated acute abdomen at Gondar University Hospital, Ethiopia.

Background: Acute abdomen is an acute onset of abdominal disease entities that require immediate surgical intervention in most of the cases. The numbers of researches done on acute abdomen in general are Very few in Ethiopia. The main objective of this study was to document the burden of acute abdomen in general and the outcome of emergency laparotomyMethods: This was a retrospective study on surgically treated acute abdomen performed at Gondar University Hospital (GUH) from September 1998 to August 2002Results: More than 1 in 10 operations done in GUH were for acute abdomen. Nearly a quarter of the operations performed in the study period were laparotomies, 43.3% of which were on emergency bases. Majority of surgically treated acute abdomen patients were from rural areas (58.2%). The sex composition was significantly different by place of residence (X2= 12.74, p=0.0017). Abdominal pain (100%), Vomiting (90.3%), abdominal distension (58.3%) and constipation (55.3%) were the commonest symptoms in patients with acute abdomen.Conclusion: This study has shown what the commonest symptoms of acute abdomen are and that the outcome of emergency laparotomy may be affected by different factors. Some of these factors were duration of illness, age, presence of peritonitis, Haematocrit level and complication detection time. Since the management is almost the same for almost all causes of surgical acute abdomens, the abovementioned factors should be given due attention in handling such patients. The reasons for low appearance of rural female dwellers to better health care centres need to be investigated

An ecological study on rodents of natural vegetation and farm lands in Siltie, Central Ethiopia

An ecological study on species composition, distribution, relative abundance and habitat association of rodents was conducted in Siltie natural vegetation and nearby farmlands during July 2008 - March 2009. Five habitat types, three from natural and two from agricultural fields were randomly selected based on representation of the main vegetation zones. In each habitat type, one representative grid was selected for live trapping. In addition, rodents were also snap-trapped from these habitats. A total of 562 captures was made in 2940 live-trap nights and 87 in 1200 snap-trap nights. Species of small mammals trapped were Mastomys natalensis (33.3%), Arvicanthis dembeensis (23.0%), Mastomys erythroleucus (12.1%), Stenocephalemys albipes (8.4%), Desmomys harringtoni (6.0%), Mus mahomet (5.9%), Tatera robusta (5.1%), Lophuromys flavopunctatus (2.8%), Rattus rattus (2.5%) and Arvicanthis niloticus (0.9%). The trap success varied significantly from habitat to habitat. Population density of rodents was high in the bush land and forest habitats. Plant matters were the most common food items revealed from the stomach contents of snap-trapped individuals. A. dembeensis, M. Mahomet, D. harringtoni and M. natalensis were recorded as major pests in the study area. Breeding was seasonal for most of the species trapped. The number of embryos varied both within and among species.An ecological study on species composition, distribution, relative abundance and habitat association of rodents was conducted in Siltie natural vegetation and nearby farmlands during July 2008 - March 2009.

Prevalence of Disability and Associated Factors among Registered Leprosy Patients in All Africa Tb and Leprosy Rehabilitation and Training Centre (ALERT), Addis Ababa, Ethiopia

BACKGROUND: Delay in leprosy diagnosis and treatment causes disabilities due to nerve damage, immunological reactions and bacillary infiltration. Leprosy disability leads not only to physical dysfunction and activity limitation but also disrupts social interaction of affected individuals by creating stigma and discrimination. This study was aimed at assessing leprosy disability status in patients registered at All African TB and Leprosy Rehabilitation and Training Centre.METHODS: Medical records of leprosy patients registered from September 11, 2010 to September 10, 2013 G.C were reviewed. Prevalence of disability calculated, bivariate and multiple logistic regressions were used to determine crude and adjusted odds ratios with 95% confidence interval.RESULTS: The overall prevalence of disability was found to be 65.9% from all categories of patients (40.2% Grade I and 25.7% Grade II). The Prevalence among the new category was 62.8% (39.1% Grade 1 and 23.7% Grade 2). Those ageed above 30 years, with duration of symptoms 6-12 months and above 24 months, with sensory loss, nerve damage and reversal reaction were more likely to develop disability.CONCLUSION: In this study the prevalence of disability, both Grade I and II, is very high. Disability was associated with age, duration of symptom, sensory loss, signs of nerve damage and reversal reaction. These risk factors indicate the existence of delay in diagnosis and treatment of leprosy cases. Therefore, the national leprosy control program should investigate leprosy case detection and diagnosis system in the country and work on improving early case detection and prevention of disability.KEYWORDS: Leprosy, leprosy disability, Ethiopi
