BackgroundAcute poisoning is a common reason for emergency department visit and hospitalization worldwide with major morbidity and mortality. The burden of poisoning exposures in Africa is a significant public health concern, but only 10 of 58 countries have poisons information centers (PICs).ObjectiveThe primary intention of our current review is to explore and summarize the published evidence on the patterns and epidemiology of poisoning in Ethiopia.MethodPubMed and Scopus were searched for primary, case series and human studies for publications from inception to July 2017. A manual search for additional relevant studies using references from retrieved articles was also performed. Only studies that reported acute poisoning in both pediatric and adult patients were included. From the screened articles, data were extracted for baseline characteristics and relevant end points such as case fatality rate, time for health institution presentation and length of hospital stay.ResultInitial entry and search resulted in the retrieval of 332 articles. Finally, 9 studies comprised of 4763 participants were included in this current review. In 78% of the studies included in this review, acute poisoning is reported to be more prevalent in females. Acute poisoning was revealed to be prevalent in less than 30 years old. Organophosphates and household cleaning agents were the predominant agents of acute poisoning. Intentional poisoning was identified responsible for the majority of acute poisoning cases and factors such as psychiatric problems, and quarrel were identified as the underlying reasons for poisoning. Time of presentation to health institution after poisoning, length of hospital stay and case fatality rate were reported and lies in the ranges between 0.2 h–24 h, 0.5 days–17.7 days and 0–14.8%, respectively.ConclusionThe occurrence of acute poisoning was higher in females and common in less than 30 years of age, making this a real public health burden in Ethiopia. Psychiatric problems, quarrel and substance abuse were identified as the most common reasons for acute poisoning. Awareness creation how to handle chemicals and prescribed drugs and psychiatric consultations should be in place for the community.
Deep venous thrombosis (DVT) is a common clinical problem associated with substantial morbidity and mortality. Knowledge of the global burden of DVT recurrence is deficient in Africa, including Ethiopia. The objective of the study was to assess deep venous thrombosis recurrence and its predictors at selected tertiary hospitals in Ethiopia. Prospective cohort study was conducted among hospitalized DVT patients. Data were analyzed using SPSS version 21.0. To identify the independent predictors of DVT-recurrence, multiple stepwise-backward Cox-regression analysis was done. Statistical significance was considered at P value < .05. A total of 129 participants were included (65.1% females) with mean ± SD age of 38.63 ± 17.67 years. About 26.4% of patients developed recurrent venous thromboembolism. Pulmonary embolism accounted for 17.60% of recurrent event. The overall incidence density of DVT recurrence was 2.99 per 1000 person-days. The mean ± SD survival time to DVT recurrence was 42.03 ± 22.371 days. Age ≥ 50 years (adjusted hazard ratio [AHR]: 5.566; 95% CI: 1.587-19.518; P = .007), occasional alcohol consumption (AHR: 2.011; 95% CI: 1.307-6.314; P = .019), surgical history (AHR: 6.218; 95% CI: 1.540-25.104; P = .010), pregnancy (AHR: 2.0911; 95% CI: 1.046-4.179; P = .037), diabetes mellitus (AHR: 8.048; 95% CI: 2.494-25.966; P < .001), unmet activated partial thromboplastin time target after 24 hours of heparin (AHR: 1.129; 95% CI: 0.120-10.600; P = .011), proximal site involvement (AHR: 5.937; 95% CI: 1.300-27.110; P = .022), and previous history of DVT (AHR: 2.48; 95% CI: 1.085-11.20; P = .0002) were independent predictors of DVT recurrence. The DVT recurrence rate was high in the study area, which is even complicated with pulmonary embolism as well as death. Efforts are needed to prevent and reduce the development of DVT recurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
