Central laboratory and point-of-care cardiac marker testing capacity of tertiary hospitals in Nigeria - a multicenter study.

Background: Cardiovascular diseases are major contributors to morbidity and mortality. It is generally recognized that cardiac markers are of particular benefit in the evaluation of patients with suspected Acute Coronary Syndrome (ACS). Tertiary hospitals, mainly teaching hospitals, are expected to be optimally equipped to offer these services. The study therefore aimed at determining the central laboratory and point-of-care cardiac marker testing capacity of tertiary hospitals in Nigeria. Method: A cross-sectional survey was carried out in government-owned tertiary hospitals in Nigeria. Data were collected using semi-structured self-administered questionnaires, and analyzed using Stata version 13 (Stata Corp., USA). Results: A total of 34 hospitals participated in the study. The mean (SD) age of respondents was 43.68 (5.2) years. A total of 19 (55.88%) hospitals were found to have a functional cardiac marker testing facility, either in the form of point-of-care, central laboratory testing or both. Of those without a facility, lack of funds to procure equipment was the major reason given. In hospitals with a testing facility, most testing devices were located in the Central laboratory. Conclusion: Cardiac marker testing capacity of tertiary hospitals in Nigeria, both in the form of point-of-care and central laboratory testing, was found to be barely adequate. Improvement is needed in this area for better diagnosis and evaluation of patients who need the tests.

Perception of problem based learning versus conventional teaching methods by clinical medical students in Nigeria.

INTRODUCTION: Problem-based learning (PBL) method which was introduced about 50 years ago in Canada is beginning to gain acceptance over conventional teaching method (CTM) worldwide in medical education but still remains unpopular in Nigeria. This study aims to determine the perception of clinical medical students to the use of both learning methods in pathology courses. METHODS: A cross-sectional quantitative survey was conducted in four Nigerian universities drawn from four regions of the country. Data were collected using pretested semi-structured self-administered questionnaires. RESULTS: The study included 310 respondents, 182(58.7%) males and 128(41.3%) females. Of all the participants, 257(82.9%) had heard of PBL prior to the study and 260(83.9%) thought it suitable for teaching and learning Pathology. Majority of participants, 221(71.3%) preferred a combination of both PBL and CTM while 238(76.8%) thought PBL suitable for all medical students. Some identified factors capable of enhancing adaptation of PBL into medical curriculum include conducive quiet spaces for learning and availability of computers with internet facilities for students' use. CONCLUSION: Participants demonstrated high level of awareness of PBL and thought it suitable for all medical students. Availability of computers and up-to-date libraries with internet and audio-visual facilities could enhance adaptation of PBL into medical curriculum in Nigeria.

Persistent microalbuminuria in human immunodeficiency virus infected children in kano, Nigeria.

Microalbuminuria has been reported to be a precursor of HIV related renal disease, which if detected early and coupled with appropriate intervention may slow or retard the progress of the disease. One hundred and seventy-eight HIV infected children aged 15 years and below were recruited from the Paediatric Infectious Disease Clinic of Aminu Kano Teaching Hospital (AKTH), Kano, to determine the prevalence of persistent microalbuminuria using the albumin creatinine ratio (ACR). Early morning urine samples and spot urine samples were analyzed using a dipstick specific for microalbumin. Those who tested positive had their samples reanalyzed in the laboratory using immunometric assay and Jaffe reaction method for albumin and creatinine, respectively. Patients that had ACR of 30-300 mg/g were said to have microalbuminuria and had their urine samples retested after 6 to 8 weeks. Twelve children (6.7%) had persistent microalbuminuria and had a mean age of 7.5 ± 3.3 years, with a male to female ratio of 1 : 1. There was no significant relationship between the finding of microalbuminuria and age, sex, duration of infection, and the use of highly active antiretroviral therapy. Periodic screening for microalbuminuria using albumin specific dipstick should be considered for children with HIV infection.
