The prevalence of orthostatic hypotension in type 2 diabetes mellitus patients in a diabetic clinic in Enugu South-East Nigeria.

BACKGROUND: Orthostatic Hypotension is a serious and common complication of diabetes mellitus. AIMS: To determine the prevalence and risk factors of Orthostatic Hypotension in type 2 diabetic patients in a diabetes mellitus clinic in Enugu South-East Nigeria. METHOD AND MATERIALS: A structured questionnaire was administered to the eligible and consenting seventy type 2 diabetes mellitus patients. The supine and erect blood pressures of each patient were recorded. The patients with Orthostatic Hypotension were compared with those without Orthostatic Hypotension for different clinical and biochemical parameters. STATISTICAL ANALYSIS USED: The data was analyzed using Statistical Package for Social Sciences (SPSS) version 19 software. Odds ratio was calculated for the presence of Orthostatic Hypotension amongst the variables and p-value < 0.05 was considered statistically significant. RESULTS: The prevalence of Orthostatic Hypotension in type 2 diabetic patients was 23.3%. Orthostatic Hypotension had statistically significant association with the presence of peripheral neuropathy, retinopathy and proteinuria. CONCLUSIONS: Orthostatic Hypotension is a common complication in type 2 diabetes mellitus patients seen at Enugu. It is recommended that measurement of erect and supine blood pressures should be part of the standard care of type 2 diabetic patients.

Successful treatment of scabies with oral ivermectin in Nigeria.

Currently, several topical scabicides are available but there is yet no oral or parenteral drug which has been established for the treatment of scabies in Nigeria. Ivermectin which is a modified avermectin, known to be an ectoparasiticidal agent in animals, has been used in adults for systemic parasitosis. In Nigeria, 25% benzyl benzoate is being extensively used for the treatment of scabies in adults. It is effective and readily available. The present study was carried out to evaluate the efficacy and safety of ivermectin in the treatment of patients with scabies at the skin clinic of the University of Nigeria Teaching Hospital, Enugu. Fifty-eight patients with scabies were recruited for the study; 13 (22.4%) were children aged between 5-14 years. Oral ivermectin was given in a single dose of 200 [microg/kg body weight to 29 patients. The remaining 29 patients had to apply 25% benzyl benzoate emulsion. All patients received a full physical and dermatological examination prior to onset of treatment and weekly for 4 weeks. Skin scrapings were taken to confirm the diagnosis of scabies. There was a 93% resolution of pruritus with ivermectin and 48% with benzyl benzoate. No side effects were observed with ivermectin. Our results show that oral ivermectin is a promising, effective and safe alternative in both children and adults of Nigeria when compared to 25% benzyl benzoate topical application.
