Chronic subdural haematoma:Clinical presentation, surgical treatment and outcome at the Lagos University Teaching Hospital

Background Chronic subdural haematoma (CSDH) is a relatively common problem in neurosurgical practice worldwide with favourable prognosis when treated adequately. The incidence is about five per 100,000 per year in general population. Incidence is higher in the elderly, about 58 per  100,000 per year. Diagnosis of CSDH is still frequently missed or delayed in our environment with many patients often admitted and managed for various medical conditions before finally being referred for brain computerized tomographic scan.Objective To determine the surgical outcome of patients treated for chronic subdural Haematoma in our environment.Methods A surgical audit of 73 patients consecutively treated for CSDH at our institution between May 2005 and September 2010 to determine their demographic characteristics, clinical presentations and management outcome.Results Majority of the patients were between 61 - 70 years. Sixty four percent of the patients had history of trauma; Only 2 patients were on anticoagulant therapy prior to presentation. The diagnosis was delayed or initially missed in 50% of the patients. Burrhole evacuation under general anaesthesia was the commonest operative procedure (96%). Five patients developed post operative complications; outcome was favourable in the majority (91.3%) of patients with a recurrence rate of 12.5% and mortality rate of 6.3%. Conclusion Despite frequent delay in diagnosis and  institution of treatment, surgical outcome is favourable in the majority of patients with CSDH many of whom are elderly

Spinal Neural Tube Defects in Lagos University Teaching Hospital, Nigeria

Background: The incidence of neural tube defects is known to vary among regions. Very little has been reported about the incidence in Sub-Saharan Africa except for the general impression that the prevalent rates are low.Objective: To determine the profile of patients presenting with neural tube defects in Lagos , NigeriaMethods: We studied all patients with congenital midline back swellings presenting to one of two neurosurgical services in the state over a 5-year period to establish the incidence of spina bifida and develop demographic data. Data collected included the age at presentation, maternal age, education and parity, presence of co-existing anomalies and the social status of the parents.Results: One hundred and eight patients with congenital midline swellings of the back were studied. Meningomyelocele accounted for 96% of the cases seen. Half the patients presented within the first two weeks of life and although fifty percent of mothers had ultrasound scans done during pregnancy none of the patients were diagnosed prenatally. Seventy-three percent of mothers of affected children were from a low socio-economic class. The commonest co-existing congenital anomaly was lower limb deformity (Talipes equino-varus).Conclusion: Spina bifida is the commonest indication for neurosurgical clinic referral with the exception of trauma in our environment. The prevalence is higher among women in the lower socio-economic groups. Improved perinatal care is required to ensure that children with such birth defects get prompt medical attention and thereby preventworsening of an already complex problem.Keywords: Neural tube defects, Spina Bifida, Myelomeningocele
