Tetanus: an analysis of the prognosticating factors of cases seen in a tertiary hospital in a developing African country between 1990 and 2000

This is an analysis of the effects of prognosticating factors on the outcome of a case series of 66 patients with tetanus, presenting between 1990 and 2000. The mortality rate was 26.2% with a fatality rate of 16.2% for those under 40 years of age. This increased to 75% for those patients above 70 years of age. The socio-economic status, immunization status, the incubation period, and age of the patient together with the severity of the spasms, duration of hospital stay, type of treatment received and time of onset were found to affect the outcome of the patients.

Effects of highly active antiretroviral therapy on cognitive functions in severely immune-compromised HIV-seropositive patients

OBJECTIVE This study assessed the effects of highly active antiretroviral therapy on the cognitive performances of HIV seropositive patients with severe immune depression. METHODS It is a prospective longitudinal interventional study of 69 anti-retroviral naïve HIV-seropositive adult patients with CD4 levels ≤ 350/μl. The cognitive assessment was done at initiation and 12 months after anti-retroviral treatment using the Community Screening Instrument for Dementia (CSID) and the computer-assisted Iron Psychology (FePsy). The impact of therapy on CD4 levels and cognitive scores of the patients before and after therapy were compared and tested for statistical significance using Student t test and one-way ANOVA. RESULTS The mean age of the patients was 36.6 ± 8.8 years. There was a significant increase in CD4 levels of the patients from 144.75 ± 88.92 at baseline to 295.91 ± 148.79 after 12 months of HAART (p<0.0001). There were significant improvements in their cognitive scores (p<0.05) in all cognitive domains tested but the finger tapping task (motor speed) did not show any improvement (p>0.05). Combination ARV drugs with efavirenz did not significantly improve attention and choice reaction time. CONCLUSION Highly active antiretroviral therapy significantly improved the CD4 levels and cognitive performances of treated HIV positive patients in all tested domains with the exception of motor speed.

Motivating Nigerian doctors for improved health care delivery

Purpose – The purpose of this paper is to examine perceptions of need dissatisfaction and need importance in the two groups of orthodox medical doctors in Nigeria, relating these motivational variables to quality in‐patient care.Design/methodology/approach – The paper draws on Maslows theory, and the question format in Heller and Porters study; 33 government‐employed doctors, and 29 private practitioners were surveyed. The “t‐test” and Mann‐Whitney test were employed in statistical analysis.Findings – The paper finds that the two groups differed significantly in perceptions of need dissatisfaction with respect to 13 of 26 need items; and in the importance attached to “opportunity to belong to social groups” and pay. When absolute values are considered, the overall picture suggests that the two groups are most dissatisfied with pay, physiological, security, self‐actualization, and transcendence needs.Practical implications – If doctors as a microcosm of Nigerian workers are to replace poor work habits wi...

Depressive symptoms in patients with epilepsy: Analysis of self-rating and physician's assessment

BACKGROUND Depression has significant negative impact on the quality of life in patients with epilepsy (PWE). AIM This study assessed the prevalence of depression in PWE and the impact of seizure variables on the depression scores. SETTINGS AND DESIGN A case-control study of randomly selected PWE attending a tertiary hospital in a metropolitan, Nigeria. MATERIALS AND METHODS A total of 152 randomly selected subjects the Beck Depression Inventory (BDI) for quantitative assessment of depression, while the Hamilton Rating Scale for Depression (HRSD) was used by the investigators. STATISTICAL ANALYSIS The Student t test assessed statistical significance of differences in the BDI and HRSD scores, whereas the scores were correlated with Pearsons correlation coefficient. Logistic regression analysis and Chi-square test for trend assessed the impact of seizure variables on the scores. The level of significance was taken as P < 0.05. RESULTS The prevalence of depressive symptoms was 42% and 45% using the HRSD and BDI, respectively, with significant differences in the scores of the patients and controls on the both scales (P < 0.001). The PWE scores on both scales yielded a correlation coefficient of 0.8 indicating their utility in detecting depressive symptoms. Seizure control was the most potent predictor of depression (HRSD: P = 0.004; BDI: P = 0.001). CONCLUSIONS Depressive symptoms are common in epilepsy. Early detection and prompt management are recommended. Good seizure control with an appropriate antiepileptic drug, among other interventional measures, may contribute to the prevention of depression in epilepsy.

Serum Lipids in Patients with Stroke—A Cross-Sectional Case-Control Study

BACKGROUND Vascular disease remains the prime contributor to the pathogenesis of stroke, but dyslipidemia has not been clearly established as a risk factor for stroke the same way it has been for coronary artery disease. There is no case-controlled study on the contribution of serum lipids to stroke in Nigerians. This study aimed at assessing the possibility of serum lipids as risk factor for stroke in Nigerian patients. METHOD The demography, blood pressure, fasting plasma glucose and fasting serum lipids of 87 consecutive patients with first-ever stroke managed at the University of Benin teaching hospital between January and December 2005 were analyzed and compared with those of age- and sex-matched controls. RESULTS Eighty-seven stroke patients (55 males and 32 females; mean age 61.25 +/- 14.77 years) were compared with age- and sex-matched controls. Ischemic stroke constituted 64.37%, while the rest had hemorrhagic stroke. There were no significant differences in the serum cholesterol, HDL-C and LDL-C levels of stroke patients and controls (p > 0.05), but the serum triglyceride level was higher among the stroke patients (p < 0.001) with a significant relative risk (RR = 1.77; p < 0.01). CONCLUSION In this cross-sectional case-control study, there is no significant difference in the serum lipids of Nigerian patients with stroke with the exception of serum triglyceride, which seems to confer significant stroke risk.

A Prototype Worldwide Survey of Diagnostic and Treatment Modalities for Stroke

Stroke is a global health problem. However, very little is known about stroke care in low- to middle-income countries. Obtaining country-specific information could enable us to develop targeted programs to improve stroke care. We surveyed neurologists from 12 countries (Chile, Georgia, Nigeria, Qatar, India, Lithuania, Kazakhstan, Indonesia, Denmark, Brazil, Belgium, and Bangladesh) using a web-based survey tool. Data were analyzed both for individual countries and by income classification (low income, lower middle income, upper middle income, and high income). Six percent (n = 200) of 3123 targeted physicians completed the survey. There was a significant correlation between income classification and access and affordability of head computed tomography scan (ρ = .215, P = .002), transthoracic echocardiogram (ρ = .181, P = .012), extracranial carotid Doppler ultrasound (ρ = .312, P ≤ .000), cardiac telemetry (ρ = .353, P ≤ .000), and stroke treatments such as intravenous thrombolysis (ρ = .276, P ≤ .001), and carotid endarterectomy (ρ = .214, P ≤ .004); stroke quality measures such as venous thromboembolism prophylaxis during hospital stay (ρ = .163, P ≤ .022), discharge from hospital on antithrombotic therapy (ρ = .266, P ≤ .000), consideration for acute thrombolytic therapy (ρ = .358, P ≤ .000), and antithrombotic therapy prescribed by end of hospital day 2 (ρ = .334, P ≤ .000). However, there was no significant correlation between income classification and the access and affordability of antiplatelet agents, vitamin K antagonists and statins, anticoagulation for atrial fibrillation/flutter, statin medication, stroke education, and assessment for rehabilitation. Our study shows that it is possible to get an overview of stroke treatment measures in different countries by conducting an internet-based survey. The generalizability of the findings may be limited by the low survey response rate.

Knowledge of the Nigerian Code of Health Research Ethics Among Biomedical Researchers in Southern Nigeria.

Responsibility for protection of research participants from harm and exploitation rests on Research Ethics Committees and principal investigators. The Nigerian National Code of Health Research Ethics defines responsibilities of stakeholders in research so its knowledge among researchers will likely aid ethical conduct of research. The levels of awareness and knowledge of the Code among biomedical researchers in southern Nigerian research institutions was assessed. Four institutions were selected using a stratified random sampling technique. Research participants were selected by purposive sampling and completed a pre-tested structured questionnaire. A total of 102 biomedical researchers completed the questionnaires. Thirty percent of the participants were aware of the National Code though 64% had attended at least one training seminar in research ethics. Twenty-five percent had a fairly acceptable knowledge (scores 50%-74%) and 10% had excellent knowledge of the code (score ≥75%). Ninety-five percent expressed intentions to learn more about the National Code and agreed that it is highly relevant to the ethical conduct of research. Awareness and knowledge of the Code were found to be very limited among biomedical researchers in southern Nigeria. There is need to improve awareness and knowledge through ethics seminars and training. Use of existing Nigeria-specific online training resources is also encouraged.

Prevalence and determinants of cognitive impairment in patients with chronic kidney disease: a cross-sectional study in Benin City, Nigeria.

BACKGROUND Chronic kidney disease (CKD) has become a public health concern and may be complicated by cognitive impairment (CI) contributing significantly to morbidity and poor prognosis. This hospital-based study aimed at determining the prevalence and the determinants of CI among CKD patients in Nigeria. MATERIALS AND METHODS A total of 190 CKD patients and a 100 healthy control subjects completed this cross-sectional study. Sociodemographic data and history of common clinical features of CKD were obtained with the use of interviewer administered semi-structured questionnaires. The six-item cognitive impairment test was used for assessment of cognitive function of patients and controls. RESULTS The prevalence of CI in Stages 3, 4, and 5 CKD patients were 24.0%, 41.6%, and 46.2%, respectively with overall prevalence of 35.3% while only 6.0% of controls had CI (P = 0.03). The most potent determinants of CI were low hematocrit (odds ratio [OR] =3.50), low serum bicarbonate levels (OR = 2.20), and high serum urea (OR = 2.11). CONCLUSION CKD is associated with significant CI in Nigerian patients especially with progressive deterioration in renal function. There is a need for regular evaluation of CKD patients for cognitive deficits.

Cognitive function in patients with newly diagnosed HIV infection in a tertiary health facility in south – west Nigeria: Assessment using computer-assisted neuropsychological test battery

Introduction Cognitive dysfunction is common among patients with human immunodeficiency virus (HIV) infection however there are few reports from sub-Saharan Africa. Methods We studied fifty seropositive patients with human immunodeficiency virus (HIV) infection along with fifty matched seronegative control. Medical history taking and general physical and neurological examinations were done for all study participants. Laboratory evaluations and chest X-ray were done for all the patients. The cognitive function was done with the aid of ‘Fepsy’ automated test battery for all the study participants. The data was analyzed with statistical package for social sciences software version 21.0 (SPSS Chicago IL). Result About 70% of the HIV patients were in advanced disease stage. The auditory and visual reaction times, binary choice reaction times, and computerized visual scanning task time were more prolonged in the HIV group (p < 0.05). There were also increased memory accuracy and binary choice task accuracy in the HIV group (p < 0.05). However the vigilance task performance was similar between the two groups (p > 0.05). Among the patients with HIV infection, the presence of anemia and central nervous system toxoplasmosis infection was associated with prolonged auditory and visual reaction times. Conclusion There was a high rate of cognitive dysfunction in patients with HIV infection in this study.

Intellectual Impairment in Patients with Newly Diagnosed HIV Infection in Southwestern Nigeria

Neurocognitive impairment is a detrimental complication of HIV infection. Here, we characterized the intellectual performance of patients with newly diagnosed HIV infection in southwestern Nigeria. We conducted a prospective study at Owo Federal Medical Center by using the adapted Wechsler Adult Intelligence Scale (WAIS). The raw scores were converted to standardized scores (z-scores) and correlated with clinical and laboratory findings. Fifty-eight HIV positive patients were recruited; 72% were in WHO stages 3 and 4. We detected a high rate of intellectual impairment in HIV positive patients and controls (63.8% and 10%, resp.; P < 0.001). HIV positive patients performed worse throughout the subtests of both verbal and performance intelligence quotients. Presence of opportunistic infections was associated with worse performance in the similarities and digit symbol tests and performance and full scale scores. Lower body weight correlated with poor performance in different WAIS subtests. The high rate of advanced disease stage warrants measures aimed at earlier diagnosis and treatment. Assessment of neurocognitive performance at diagnosis may offer the opportunity to improve functioning in daily life and counteract disease progression.
