Ten-year mortality review in a pioneer psychiatric hospital in West Africa

Objective: To determine the mortality among admitted patients in the study centre, a pioneer psychiatric facility in the West African sub-region. Design: A detailed retrospective study of the records of all deaths among the inpatients during the ten-year period of January, 1991 to December, 2000. Setting: Psychiatric Hospital Yaba, Lagos, Nigeria; established in 1907 with present bed status of 535 and patronage from Lagos and it's environ, including the neighbouring Benin Republic. Subjects: Ninety six patients that died while on admission in the centre during the study period. Results: A total of 96 patients died over the ten-year period, giving an annual rate of 9.6. The age range was 14-87 years, and mean of 44.4 (SD ±16.8) years. The male: female ratio was 1:1.6. Schizophrenia (26%) and major depression (25%) constituted the main psychiatric diagnoses at the time of admission among the cohort. The commonest cause of death included infections/infestations, most especially malaria and septicaemia (44% of the cohort). Conclusion: It is concluded that the major psychotic disorders, schizophrenia and depression continue to constitute the highest psychopathologies diagnosed psychiatric mortality study. Finally, infections/infestations still continue to play leading role as major causes of death in the West African sub-region. East African Medical Journal Vol.80(7) 2003: 379-38

Kola nut from Cola nitida vent. Schott administered to pregnant rats induces histological alterations in pups’ cerebellum

Kola nut (from Cola nitida) is popular in Nigeria and West Africa and is commonly consumed by pregnant women during the first trimester to alleviate morning sickness and dizziness. There is, however, a dearth of information on its effects on the developing brain. This study, therefore, investigated the potential effects of kola nut on the structure of the developing neonatal and juvenile cerebellum in the rat. Pregnant Wistar rats were administered water (as control) or crude (aqueous) kola nut extract at 400, 600, and 800 mg/kg body weight orally, from pregnancy to day 21 after birth. On postnatal days 1, 7, 14, 21 and 28, the pups were weighed, anaesthetised, sacrificed and perfused with neutral buffered formalin. Their brains were dissected out, weighed and the cerebellum preserved in 10% buffered formalin. Paraffin sections of the cerebellum were stained with haematoxylin and eosin for cerebellar cytoarchitecture, cresyl violet stain for Purkinje cell count, Glial Fibrillary Acidic Protein (GFAP) immunohistochemistry (IHC) for estimation of gliosis, and B-cell lymphoma 2 (Bcl-2) IHC for apoptosis induction. The kola nut-treated rats exhibited initial reduction in body and brain weights, persistent external granular layer, increased molecular layer thickness, and loss of Bergmann glia. Their Purkinje cells showed reduction in density, loss of dendrites and multiple layering, and their white matter showed neurodegeneration (spongiosis) and GFAP and Bcl-2 over-expression, with evidence of reactive astrogliosis. This study, therefore, demonstrates that kola nut, administered repeatedly at certain doses to pregnant dams, could disrupt normal postnatal cerebellar development in their pups. The findings suggest potential deleterious effects of excessive kola nut consumption on human brain and thus warrant further studies to understand the wider implications for human brain development

Five-year mortality in a cohort of people with schizophrenia in Ethiopia

<p>Abstract</p> <p>Background</p> <p>Schizophrenia is associated with a two to three fold excess mortality. Both natural and unnatural causes were reported. However, there is dearth of evidence from low and middle income (LAMIC) countries, particularly in Africa. To our knowledge this is the first community based report from Africa.</p> <p>Methods</p> <p>We followed a cohort of 307 (82.1% males) patients with schizophrenia for five years in Butajira, rural Ethiopia. Mortality was recorded using broad rating schedule as well as verbal autopsy. Standardized Mortality Ratio (SMR) was calculated using the mortality in the demographic and surveillance site as a reference.</p> <p>Result</p> <p>Thirty eight (12.4%) patients, 34 men (11.1%) and 4 women (1.3%), died during the five-year follow up period. The mean age (SD) of the deceased for both sexes was 35 (7.35). The difference was not statistically significant (p = 0.69). It was 35.3 (7.4) for men and 32.3 (6.8) for women. The most common cause of death was infection, 18/38 (47.4%) followed by severe malnutrition, 5/38 (13.2%) and suicide 4/38 (10.5%). The overall SMR was 5.98 (95% CI = 4.09 to7.87). Rural residents had lower mortality with adjusted hazard ratio (HR) of 0.30 (95% CI = 0.12-0.69) but insidious onset and antipsychotic treatment for less than 50% of the follow up period were associated with higher mortality, adjusted HR 2.37 (95% CI = 1.04-5. 41) and 2.66(1.054-6.72) respectively.</p> <p>Conclusion</p> <p>The alarmingly high mortality observed in this patient population is of major concern. Most patients died from potentially treatable conditions. Improving medical and psychiatric care as well as provision of basic needs is recommended.</p
