Comparative cardiac effects of antimalarial drug halofantrine with or without concomitant administration of kolanut or fluconazole in healthy volunteers.

Background: There is rekindled interest in the cardiotoxicity of antimalarial medicines. Halofantrine is associated with QT interval prolongation. Fluconazole and kolanut alter the pharmacokinetics of halofantrine.

Cohort study on adverse drug reactions in adults admitted to the medical wards of a tertiary hospital in Nigeria: Prevalence, incidence, risk factors and fatality.

Aims: Intensive monitoring of medical patients for adverse drug reactions (ADRs) to assess prevalence, incidence, risk factors and fatality of ADRs leading to hospital admission or occurring in the hospital.

Methods: Prospective cohort study on 1280 adult patients admitted to the medical wards of a tertiary institution over 12 months. Patients were assessed for ADRs during and throughout admission; causality and preventability of ADRs were assessed.

Assessment of iron deficiency anaemia and its risk factors among adults with chronic kidney disease in a tertiary hospital in Nigeria.

Introduction: A substantial proportion of patients with chronic kidney disease (CKD) develop iron deficiency anaemia (IDA). Despite the association of IDA with adverse cardiovascular outcomes, it remains underdiagnosed and poorly managed. Up to 70% of patients with CKD are anaemic at the time of initiating dialysis, while the predictors of IDA in these patients in our setting are unknown.

Outcome of Radioiodine Therapy in a West African Population.

Hyperthyroidism continues to be a pressing public health concern in West Africa. Its prevalence in Africa has been quoted as 1.2%-9.

Radiation Levels from Toilets Used By Patients Injected with 99mTc-based Radiopharmaceuticals in Ibadan.

Objective: The use of radionuclides in patients undergoing nuclear medicine procedures presents a special concern on the safety of not only the patients but also of those who come in contact with such patients either at the nuclear medicine centre or at home after discharge from the facility. This has heightened the public concern about nuclear medicine especially in Nigeria where the practice is new. When patients are injected with radioactivity for nuclear medicine procedures they excrete most of the radioactivity via urine even before leaving the nuclear medicine facility.

Avoidable challenges of a nuclear medicine facility in a developing nation.

The role of nuclear medicine in disease management in a developing nation is as impactful as it is in other regions of the world. However, in the developing world, the practice of nuclear medicine is faced with a myriad of challenges, which can be easily avoided. In this review, we examine the many avoidable challenges to the practice of nuclear medicine in a developing nation.

Significant bacteriuria among asymptomatic antenatal clinic attendees in ibadan, Nigeria.

Untreated asymptomatic bacteriuria can lead to urinary tract infection (UTI) in pregnancy with devastating maternal and neonatal effects such as prematurity and low birth weight, higher fetal mortality rates and significant maternal morbidity. We carried out a two year (April 2007 to March 2009) cross-sectional epidemiological study to determine the prevalence of significant bacteriuria among asymptomatic antenatal clinic attendees at two antenatal clinics (ANCs) in University College Hospital and Adeoyo Maternity Hospital, both in Ibadan, Nigeria.All consenting ANC attendees without UTI were enrolled in the study.

Gamma camera intrinsic uniformity in an unstable power supply environment.

The main objective of this work was to show that a gamma camera in a developing country could perform efficiently despite electricity outages using intrinsic flood uniformity tests as an index of performance. A total of 143 intrinsic uniformity test results for a new gamma camera in use in an environment with unstable power supply are presented. The integral uniformity for the central field of view (CFOV) was found to be between 3.

Data on repeated (131)I-WB scans and the incidence of positive Tg and negative (131)I-WBS in DTC patients from a 24 months study.

We present data on repeated iodine-131 whole body scans ((131)I-WBS) in differentiated thyroid cancer patients (DTC) after surgery and (131)I remnant ablation and on increased thyroglobulin (Tg) with negative (131)I-WBS, in a retrospective study at our hospital. A total of 106 patients (91 female and 15 male) treated with (131)I for DTC met the inclusion criteria. The mean age of the patients was 45 years, age range 16-81 years.

Prevalence of hepatitis B and C seropositivity in a Nigerian cohort of HIV-infected patients.

Introduction: The clinical and public health implications of the convergence of the human immunodeficiency virus (HIV) epidemic and chronic viral hepatitis in sub-Saharan Africa are poorly understood. This study was designed to determine the seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV), and the impact of co-infection on baseline serum alanine transaminase (ALT), CD4+ T lymphocyte (CD4) count, and plasma HIV-RNA (viral load) in a cohort of HIV-infected Nigerians.

Methods: A retrospective study was conducted, on eligible treatment-naive patients who presented between August 2004 and February 2007 to the University College Hospital (UCH), Ibadan, Nigeria.

Microalbuminuria in pregnancy as a predictor of preeclampsia and eclampsia.

Introduction: Hypertensive disorders of pregnancy are common major complications of pregnancy and are responsible for significant morbidity and mortality in the fetus, the newborn infant and the mother.

Objectives: To access if a single estimation of urinary microalbumin at booking would be of value in the prediction of subsequent development of preeclampsia or eclampsia

Methods: We studied at booking urinary microalbumin excretion in one hundred healthy normotensive Nigerian pregnant women attending the antenatal clinic and followed them till delivery. The women were grouped into 3 i.
