Characteristics and Outcome of Paediatric Traumatic Brain Injuries: An Analysis of 163 Patients in Enugu

Background: As with most ailments common to adult and paediatric age groups, studies that describe and characterize paediatric traumatic brain injuries (TBIs) lag those of their adult counterparts. This is more so in the developing countries where national data are not well developed. The development of local clinical  guidelines has been shown to positively impact outcomes of paediatric TBI. Data on the characteristics and outcomes of TBI among paediatric age groups will provide a framework for the development of an  all‑encompassing management guideline. Methods: In this study, a retrospective review of demography, mechanism of injury, pattern of presentation, nature of treatment, duration of hospital admission, and outcome of children aged 0–17 years managed for traumatic TBI at the University of Nigeria Teaching Hospital, Enugu‑Nigeria was performed. Data were analyzed using SPSS version 21. Relevant test statistics were used to test for associations. AP = 0.05 was considered  statistically significant. Results: Atotal of 163 patients’ medical records were retrieved and analyzed. Of these, 117 (71.8%) were males and 46 (28.2%) were females. Their ages ranged from 6 weeks to 17 years with a mean age of 7.66 ± 5.1 years and peaked at 3–5 years. No difference in mean age between gender (P = 0.427). Pedestrian motor vehicular accident was the most common cause of injury. Fall from fruit trees and assault were peculiar to children from suburban/rural areas. TBI severity on admission was mild (44.2%), moderate (38.7%), and severe (17.2%). Other systemic injuries were present in 33.7%, of which long bone fractures were the most common (23/55). Abnormal brain computed tomography findings were seen in 83.2% with skull fracture being the most common finding. Operative procedures were carried out on 19.6% of patients. Conservative measures were the mainstay of management. The mean  duration of hospital admission was 14.01 ± 11.8 days was significantly associated with admission Glasgow Coma Scale (GCS) Score (P < 0.0001) and Glasgow Outcome Score (GOS) at discharge (P = 0.03). The overall outcome was good (GOS 4 and 5) in 92.0% and has a significant association with GCS on admission (P < 0.0001). Long‑term (Extended GOS) was 8 in 98.2% of those followed up. Conclusion: Paediatric TBI is mainly mild to moderate in severity with a male predilection. The main cause is road traffic accidents with most victims being pedestrians. Management is mainly non-operative and the outcome at discharge is good even in a middle‑income country and significantly determined by GCS on admission

Preliminary Findings on Metastatic Brain Tumors in Enugu, Southeast Nigeria

Background: Metastatic brain tumors (MBTs) are the most common brain neoplasms seen clinically and are often associated with poor outcomes. This study highlights the demographic, clinical, and radiological profiles as well as outcomes of MBTs managed in a tertiary hospital in Southeast Nigeria. Methods: This was a 1-year prospective observational study of patients with MBT who presented to the neurosurgery unit of the University of Nigeria Teaching Hospital, Enugu, from December 2018 to November 2019. Data on the demography, clinical and radiological features, treatment, and outcomes were collected and analyzed. Results: Of the 31 patients with MBTs, 58.1% were female and 41.9% male. The mean age was 51.0 ± 15.2 years. The most common presenting features were limb weakness (77.4%), headache (58.1%), and personality changes (54.8%). About a quarter (26.7%) were fully conscious at  presentation. Only 45.2% knew that they had a systemic malignancy (SM) before presentation. The breast (29.0%), lungs (22.6%), and skin (19.3%) were the common sources of metastases. The lesions were solitary in 25.8% and multiple in 74.2%. They were predominantly frontal (80.6%), with bilateral distribution in 64.5% of patients. Radiotherapy was done in 58.1% and surgery in 6.5% of patients. Prior knowledge of the existence of a SM (P = 0.045) and unilateral brain involvement (P = 0.013) were associated with better 30-day survival. Conclusion: The breast is the most common source of brain metastasis. Prior knowledge of the existence of a SM and unilateral brain involvement is associated with better short-term survival.

Chest Injuries Associated with Head Injury

Background: Although there have been significant advances in the management of traumatic brain injury (TBI), associated severe injuries, in particular chest injuries, remain a major challenge. This paper analyses the contribution of chest injuries to the outcome of head injuries in the University of Nigeria Teaching Hospital (UNTH) and the Memfys Hospital for Neurosurgery (MHN) in Enugu, Nigeria. Materials and Methods: This is a retrospective review of the medical records, operative notes, and radiological findings of all patients admitted for head injury who had associated significant chest injuries in the MHN from 2002 to 2009 and the UNTH between 2007 and 2010. Patients with only head injury and other extracranial injury not affecting the chest were excluded. Patients who were inadequately investigated were also excluded. Results: Nineteen patients from the MHN and 11 patients from the UNTH were analyzed. Ages ranged from 9 to 65 years and the male:female ratio was 3:1. Injuries were most common between 30 and 50 years and road traffic accident accounted for 60%. Barotrauma from ventilation was documented in 2 patients. The commonest types of intrathoracic injuries are pneumothorax and hemothorax. Chest wall injuries are more common but carry less morbidity and mortality. Only 20% of patients presented within 48 hours of injury. Management of the associated chest trauma commenced in the referring hospitals only in 26.4% of the patients. All patients with hemopneumothorax had tube thoracostomy as did 96% of patients with pneumothorax. 10% of patients with haemothorax needed thoracotomy. Mortality is 43%, which is higher than for patients with only TBI with comparable Glasgow coma scale. Outcome is influenced by the time to admission and the GCS on admission. Conclusion: Associated chest injuries result in higher mortality from head injuries. This association is more likely in the young and more productive. All patients presenting with head and spinal cord injury should be specifically and carefully evaluated for associated chest injuries. Computerized tomographic has not replaced the need for good quality chest radiograph in the emergency management of Head Injury associated chest trauma.Keywords: Chest injuries, head injuries, outcomeNigerian Journal of Surgery, Jan-Jun 2012 | Volume 18 | Issue

Intracranial meningiomas managed at Memfys hospital for neurosurgery in Enugu, Nigeria

Introduction: The epidemiology and pathology of meningioma in Nigeria are still evolving and little has been published about this tumor in Nigeria, especially in the southeast region. The aim of this paper is to compare the characteristics of intracranial meningioma managed in our center with the pattern reported in the literature worldwide. Materials and Methods: Retrospective analysis of prospectively recorded data of patients managed for intracranial meningioma between January 2002 and December 2010 at a Private neurosurgery Hospital in Enugu, Nigeria. We excluded patients whose histology results were inconclusive. Results: Meningiomas constituted 23.8% of all intracranial tumors seen in the period. The male to female ratio was 1:1.1. The peak age range for males and females were in the fifth and sixth decades, respectively. The most common location is the Olfactory groove in 26.5% of patients followed by convexity in 23.5%. Presentation varied with anatomical location of tumor. Patients with olfactory groove meningioma (OGM) mostly presented late with personality changes and evidence of raised ICP. Tuberculum sellar and sphenoid region tumors presented earlier with visual impairment with or without hormonal abnormalities. Seizures occurred in 30.9% of all patients and in 45% of those with convexity meningiomas. Only 57.4% of the patients were managed surgically and there was no gender difference in this group. WHO grade1 tumors were the most common histological types occurring in 84.6%. One patient had atypical meningioma and two had anaplastic tumors. Conclusion: The pattern of meningioma in our area may have geographical differences in location and histology. Childhood meningioma was rare

The Challenges of Management of High-grade Gliomas in Nigeria

Background: High-grade gliomas (HGG) are among the most challenging brain tumors despite many research efforts worldwide. Aim: The aim of this study was to evaluate the local challenges that may influence outcome of HGG managed in a neurosurgical center in Nigeria. Methodology: Retrospective analysis of prospectively recorded data of patients managed for intracranial HGG at Memfys Hospital for Neurosurgery, Enugu, Nigeria, between the year 2006 and 2015. Only cases with conclusive histology following surgery were analyzed. Results: Glioma was 60 (23.8%) of 252 histology confirmed brain tumors. HGG represented 53.8% of gliomas with male:female ratio of 2.2:1.0 and peaked from fifth decade of life. Glioblastoma multiforme accounted for 69% of HGG. At 1-year postsurgery, 53% of HGGs were dead and 88% of these deaths were in the World Health Organization Grade IV group. Only 40% of cases could receive adjuvant treatment with only 15% mortality at 1 year in this subgroup that received adjuvant therapy. In addition, 19% of cases had surgery at Karnofsky score (Ks) of ≤70%. However, 94% of mortality at 1 year was related to surgery at Ks of ≤60%. Only four patients had a tumor volume of ≤50 cm3, and among these cases, three patients were independent at 1 year. Patients with tumor volume above 50 cm3 accounted for 94% of mortality. Conclusion: The peak age incidence for HGG seems to be lower than in Caucasians. Most cases present late with poor Ks and big tumor volume. The proportion with access to adjuvant treatment is still poor. Preoperative Karnofsky, extent of resection, duration of hospital, and Intensive Care Unit stay have impact on outcome

Surgically Treated Primary Spinal Cord Neoplasms in Southeastern Nigeria

Background: Primary spinal cord tumors are not as frequently encountered as their cranial counterparts. They could present in such an indolent manner that requires a reasonable index of suspicion for their diagnosis to be considered. Objective: The objective of this study is to analyze the incidence and pattern of primary spinal cord and appendage neoplasms in patients surgically treated in our institution over a decade of practice. Materials and Methods: A retrospective review of clinical, radiological, and histopathology profiles of patients surgically treated for primary spinal cord tumor from 2006 to 2016 was carried out. Retrieved data were analyzed using SPSS version 21. Results: Out of 472 spine procedures were performed within the study period 17 (3.6%) cases of histologically proven primary spinal cord tumors were identified. The age of patients ranged between 17 and 77 years with a mean age was 45 years. The male: female ratio was 1:1.1. Motor deficit and pain were the most common presenting symptoms seen in 35.3% and 29.4% of patients, respectively. Meningiomas are the most common histological diagnosis (70.6%), distantly followed by Schwannoma (17.6%). The most common location of the tumors was intradural extramedullary (70.6%). All patients had gross total resection of tumor with no perioperative mortality. Conclusion: Meningioma is the most common surgically treated primary spinal cord tumor in our setting. Surgery is associated with good outcome

Management of brain abscess: Changing trend and experience in Enugu, Nigeria

Background: Intracranial abscess remains a significant health-care problem. Its causes, diagnosis, treatment, and outcome are changing. Aim: This paper reviewed the demography, examined new trends, and compared outcomes with different treatment options. Methodology: Retrospective analysis of intracranial abscesses managed at Memfys Hospital, Enugu (2004–2014) and University of Nigeria Teaching Hospital (2009–2014). Patients were followed up for at least 6 months. All patients had neuroimaging before intervention. Microscopy and culture were performed for the specimens. Intravenous antibiotics were given for 2 weeks before conversion to oral. Results: Seventy-nine parenchymal abscesses (eight cases per year) were managed. Peak age was the second decade of life. Previous head injury (21.5%) and meningitis (16.5%) were the most common predisposing factors. The frontal lobe was most common anatomical location (32%). Only 24% had positive culture result. Three cases were fungal infections. Seventy percent of patients managed with burr hole drainage and 37.5% of craniotomy made complete recovery. Overall, 58% of patients made complete recovery, whereas 19.0% died. Nine percent of cases died before definitive intervention. Among the 24% of patients that presented in coma, 47% died within 6 months. Most important factor influencing mortality was admission level of consciousness. Abscess recurred in 6% of cases. Conclusion: Intraparenchymal abscesses in Enugu were mostly solitary lesions resulting from poorly managed head injury and meningitis. Predisposition from otitis media and systemic diseases has reduced. The proportion of fungal organisms is increasing. A significant proportion of the patients present in coma. Burr hole and aspiration of abscess is less invasive and has very good outcome

Modified Laminoplasty for Degenerative Cervical Spondylosis: The Technique of Floating Laminoplasty

Background: Laminoplasty is an established alternative to laminectomy for posterior cervical decompression in spondylotic myelopathy. However, standard laminoplasty requires internal fixation, which is often not obtainable in developing countries. We present our experience with a technique of noninstrumented (floating) laminoplasty developed to avoid the need to anchor the laminoplasty to the anterior elements. Methods: We have used floating laminoplasty (FL) for posterior cervical decompression in patients with cervical spondylosis since 2004 and report the technique and our experience with it between 2009 and 2014 when C-arm and magnetic resonance imaging became available in our unit. Patients who had classical laminectomy and hemilaminectomies were excluded. The operation involved bilateral approach to the laminae through a midline incision with generous sparing of the supraspinous, interspinal and interlaminar ligaments. During closure the laminoplasty was hitched to the ligamentum nuchae. Nurick grading was used for clinical evaluation. Patients were followed for at least 1 year. Results: There were 36 patients with age range between 32 and 72 years (mean: 56.5 years). Male to female ratio was 3:1. Most patients presented with advanced disease, with 25%, 36%, and 30% at Nurick Grade 3, 4, and 5, respectively. Postoperatively, all (100%) patients with Nurick Grade 2 and 3 improved to Grade 1 or 0, while 9 (69%) of the 13 at Grade 4 improved to Grade 2 or better. Only 1 (9.1%) of 11 operated at Grade 5 did not improve while 3 (27%) improved to Grade 2 or better. No postoperative instability was identified on follow-up. Conclusion: FL is a safe and simple procedure that preserves spine stability and minimizes postoperative spinal deformity
