Plasma level distribution, effect and toxicity of antiepileptic drugs among Ethiopian epileptics

Plasma phenytoin and phenobarbitone levels were estimated in 123 adult Ethiopian epileptics by gas-liquid chromatography. Thirty four (38.2%) of the patients on phenytoin, and 52 (52%) of those on phenobarbitone, had plasma levels in the conventional therapeutic ranges of 10-20 micrograms/ml and 10-30 micrograms/ml respectively. Of the 89 patients who were taking phenytoin either singly or combined with phenobarbitone, motor disturbances (ataxia and nystagmus) were seen in 31 (34.8%) and dysmorphic and idiosyncratic side effects including gum hypertrophy, hirsutism, acne and skin rash in 37 (41.6%). Subnormal serum calcium levels were noted in 15 (30.6%) and high alkaline phosphatase was found in 13 (26.5%). Phenobarbitone was found to be an effective anticonvulsant (78.1% seizure control rate), with adverse effects of sedation and intellectual depression. Seizure control was achieved in 77.1% of patients on a single drug as opposed to 55.6% on combination of phenytoin and phenobarbitone (p less than 0.05). The overall seizure control rate was 66%.     

Modeling Time to Cure of Deep Vein Thrombosis Using Cox Proportional Model in Southwest of Ethiopia

BackgroundGlobally, there are about 10 million cases of deep vein thrombosis every year, and it is the third leading cardiovascular disease after myocardial infarction and stroke. The objective of the study is to assess risk factors of time to cure patients of deep vein thrombosis in southwest Ethiopia.MethodsA retrospective cohort study design was used. The study population was deep vein thrombosis patients at purposively selected hospitals in Southwest Ethiopia from January 2017 to December 2020. Cox proportional hazard model was used to identify risk factors associated with deep vein thrombosis.ResultsOut of the total 1068 registered as deep vein thrombosis patients, 263(24.6%) were cured during the study period, and 805(75.4%) were censored. Results of the Cox proportional hazard model show that; age, gender, family history of deep vein thrombosis, smoking status, immobilize and alcohol consumption were factors associated with deep vein thrombosis (p-value<0.05).ConclusionThe patients with a family history of deep vein thrombosis, prolonged immobilization, greater the 50 years, smoking cigarettes, female (non-pregnant) and alcohol users had a longer curing time of deep vein thrombosis compared to others.     

Pleural effusion and pneumothorax in hospitalized patients with HIV infection: the Pulmonary Complications, ICU support, and Prognostic Factors of Hospitalized Patients with HIV (PIP) Study

OBJECTIVES: To describe the incidence, causes, and impact of pleural effusion and pneumothorax in hospitalized patients with HIV infection. DESIGN: Prospective, observational. SETTING: A university-affiliated medical center. METHODS: During a 3-year period, 599 HIV-infected patients with a total of 1,225 consecutive hospital admissions were followed. A total of 1,097 hospital admissions were included. Patients' medical records, chest radiographs, and computerized laboratory values were reviewed. RESULTS: Pleural effusions developed in 160 hospital admissions (14. 6%). The effusions were right sided (56%), left sided (29%), and bilateral (15%). Their sizes were small (65%), moderate (23%), large (9%), and massive (4%). The associated conditions were infectious: bacterial pneumonia (n = 50), pulmonary tuberculosis (n = 10), Pneumocystis carinii pneumonia (PCP; n = 5), and empyema (n = 2); and noninfectious: renal failure (n = 15), hypoalbuminemia (n = 12), malignancy (n = 9), pancreatitis (n = 7), hepatic cirrhosis (n = 5), congestive heart failure (n = 4), atelectasis (n = 3), pulmonary embolism (n = 3), trauma (n = 1), and surgery (n = 1). Pneumothorax developed in 13 hospital admissions (1.2%). The conditions associated with pneumothorax were iatrogenic (n = 4), bacterial pneumonia (n = 3), PCP (n = 2), positive pressure ventilation for PCP (n = 2), pulmonary Mycobacterium avium complex (n = 1), and trauma (n = 1). The in-hospital mortality of hospital admissions with pleural effusion was 10.0% compared to 5.4% of those without pleural effusion (p = 0.0407). The in-hospital mortality of hospital admissions with pneumothorax was 30.8% compared to 5.8% of those without pneumothorax (p = 0.0060). CONCLUSIONS: Pleural effusions occur in 14.6% of hospital admissions in our patient population with HIV infection. Bacterial pneumonia is the condition most commonly associated with pleural effusion. Pneumothorax, seen in 1.2% of hospital admissions with HIV infection, is associated with poor outcome.     

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.     

Pneumocystis carinii pneumonia complicated by lymphadenopathy and pneumothorax

A case of generalized Pneumocystis carinii infection presented as hilar and mediastinal lymphadenopathy and was complicated by spontaneous pneumothorax. Extrapulmonary P carinii infection in patients with acquired immunodeficiency syndrome is rare, and pneumothorax is even rarer. The purpose of this report is to call attention to these atypical features of P carinii infection in patients with the acquired immunodeficiency syndrome.
