Female monozygotic twins with sacral myelomeningocele.

Background: Concurrent myelomeningocele in twins is a rare clinical presentation, only reported twice in Nigeria. Case Description: We present a set of identical female twins from Nigeria. Both twins were females that presented at 3 years with low back swelling since birth, associated with bisphincteric dysfunction but normal motor and sensory functions in the lower extremities. They had repair of myelomeningocele 2 months after presentation and there was no new deficit postoperatively.There was no family history of neural tube defects and it would have been good to do genetic studies in this case but we do not have facilities for such. Conclusion: This is the first reported case of identical twins with concurrent myelomeningocele and preserved motor functions in the lower limbs in Nigeria and West Africa.

Chronic Subdural Hematoma: Predicting Postoperative Recurrence Using a Correlation of Computerized Tomographic Volume with Intraoperative Volume.

Background: Chronic subdural hematoma (CSDH) recurrence is the most common complication following surgery. Objective: To predict postoperative recurrence of CSDH using a correlation of the calculated preoperative brain computerized tomographic (CT) volume with the intraoperative volume. Materials and Methods: A prospective study was conducted over 14 months in a tertiary hospital in southwestern Nigeria. History with focused examination findings and patient grading using Markwalder classification were documented preoperatively. Preoperative CSDH CT volume was documented and compared with the intraoperative volume. Patients were followed up clinically for features of recurrence at 1, 3, and 6 months postoperatively, and repeat brain CT was done when recurrence was suspected clinically. Results: Forty-seven out of 51 patients recruited completed the study, and four were lost to follow-up. Thirty-three (70.2%) were males, and the average age was 51.4 years. Most of the patients were in the 5th and 7th decades of life. Three patients had recurrence (6.5%), and one patient died (2.1%). Trauma was the most common cause of CSDH (35 out of 47 [74.5%]), spontaneous in 11 (23.4%), and anticoagulant related in 1 (2.1%) patient. Most patients (37/47; 78.7%) presented with headache. The mean brain CT volume and intraoperative volume of CSDH were 102.58 ± 54.13 and 87.74 ± 46.6 mL, respectively, with no significant difference between them (P = 0.104). The receiver operating characteristics curve of intraoperative volume predicted the recurrence of CSDH at a volume >130 mL, with a sensitivity of 66.7%. Conclusion: The calculated preoperative CT volume had a positive linear correlation with intraoperative volume. Intraoperative CSDH volume >130 mL was associated with an increased risk of recurrence.

Contemporary Management of Intracranial Subdural Empyema: An Institutional Experience.

Background: Intracranial subdural empyema (SDE) is a seemingly uncommon life-threatening ailment with varying presentations and outcomes. A variety of risk factors have been associated with predisposition to intracranial SDEs; however, they may be cryptogenic. There is an increased predilection for intracranial SDE in children and teenagers with paranasal sinusitis or middle ear infections. The clinical presentation is non-specific and thus a high index of suspicion is required. Neuroimaging is an invaluable diagnostic tool for early diagnosis and surgical intervention. There have been multiple proponents for either burr hole or craniotomy to treat intracranial SDEs; however, despite surgical intervention, adverse neurologic sequelae and even mortality still occur. Extended antibiotic therapy is mandatory and impacts significantly on patients' outcomes. Objectives: This study describes the demographics, clinical presentation, and surgical outcomes in patients with intracranial SDEs over the study period. Design: This is a retrospective single-centre case series. Setting: This study takes place in a tertiary referral centre, university hospital. Materials and Methods: This was a retrospective review of patients presenting with intracranial SDEs over a 10-year period in a tertiary neurosurgical unit serving south-western Nigeria. Demographic, clinical, and radiologic data were retrieved from patient records. Results: Forty-nine patients presented with intracranial SDEs during the review period. These patients aged between 16 months and 75 years, most of whom were 20 years of age and below. The mean age was 21.37 ± 19.29 years with a median age of 15 years. There were 35 males and 14 females giving a male-to-female ratio of 2.5:1. The most common presentations were headache (73.5%), altered sensorium (55.1%), and seizures (38.8%). Forty patients (81.6%) had evacuation of SDE by burr hole and subdural washout. There was a significant post-op residual SDE in six patients. There were eight (16.3%) mortalities in this series. Forty-seven (95.9%) patients had sterile cultures of the subdural pus collection. Conclusion: Intracranial SDE affects mostly children and teenagers. Early diagnosis, emergent surgery, extended antibiotic therapy, and concurrent source control employing a multidisciplinary approach are essential in managing this condition. Burr hole and subdural washout help control the disease process, reduce operation time, and may yield outcomes similar to craniotomies, which are more invasive.

Early Outcome of Endoscopic Third Ventriculostomy With Choroid Plexus Cauterization Versus Ventriculoperitoneal Shunt as Primary Treatment of Hydrocephalus in Children With Myelomeningocele: A Prospective Cohort Study.

BACKGROUND: Myelomeningocele is associated with hydrocephalus in 35% to 90% of cases. Hydrocephalus is usually treated with insertion of ventriculoperitoneal shunt; however, there is growing evidence that endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) is an alternative. OBJECTIVE: To compare the success rate and morbidity of ETV with CPC and ventriculoperitoneal shunt (VPS) as the primary treatment of hydrocephalus in patients with myelomeningocele. METHODS: A prospective study from January 2016 to February 2019, involving 46 patients with myelomeningocele who developed hydrocephalus after repair in a tertiary hospital in southwestern Nigeria. Biodata and preoperative features of hydrocephalus were documented. ETV + CPC or VPS was done using standard operative techniques. Patients were followed up monthly for 6 mo. RESULTS: There were 23 patients in the ETV + CPC arm and 22 patients in the VPS arm. Morbidities were cerebrospinal fluid leak, 8.3% in the ETV + CPC arm and 4.5% in the VPS arm, wound dehiscence, 13.6% in the VPS arm, none in the ETV + CPC arm. At 6-mo follow-up, success rate for ETV + CPC was 60.9% and 59.1% for VPS, P = .9. CONCLUSION: ETV + CPC had similar success rate with VPS at 6 mo with lower morbidity. ETV + CPC should be considered a viable alternative when treating patients with myelomeningocele and hydrocephalus.

Knowledge, attitudes and screening practices regarding prostatic diseases among men older than 40 years: a population-based study in Southwest Nigeria.

INTRODUCTION: Despite the global increase in awareness of prostatic diseases resulting from widespread availability of screening tools, there is no evidence that the knowledge, attitudes and screening practices of Nigerian men have improved regarding prostatic diseases. METHODS: A descriptive cross-sectional study amongst 305 community-dwelling men. Respondents were selected using multi-staged sampling techniques. Knowledge, attitudes and screening practices were determined based on responses to a semi-structured KAP questionnaire. Data were analyzed using SPSS version 18. Pearson's chi-square and Fisher's exact test (two-tail) with level of significance set at 0.05 were used to determine the level of statistical significance. Pearson's correlation coefficient was used to establish correlation between variables. RESULTS: Mean age of respondents was 63.4±11.8 years. Slightly less than half, 145(47.5%) were aware of prostate cancer (PCa) while only 99(32.5%) and 91(29.8%) were aware of BPH and prostatitis respectively. About a quarter (25.1%) had heard of PSA. The main sources of information were radio and television. Overall, 143(46.9%) respondents had good knowledge while 162(53.1%) had poor knowledge. Sexually transmitted disease was the commonest misconception as the cause of prostatic diseases. Overall, 44.3% had good attitudes. Only 31(10.2%) respondents had ever carried out screening for PCa. Only educational and occupational status had significant associations with level of knowledge and attitudes of participants. The only factor that influenced screening practices was educational status. CONCLUSION: There is a poor level of knowledge, attitudes and screening practices regarding prostatic diseases in Nigeria. We recommend a widespread public health education to improve knowledge, attitudes and screening practices for prostatic diseases.
