Publication Demography and Outcome of Pediatric Traumatic Brain Injury; Experience from a University Teaching Hospital in Nepal(Institute of Medicine, 2022) Dahal, Sandesh; Shrestha, Dipendra K; Pradhanang, Amit B; Sedain, Gopal; Shilpakar, Sushil K; Sharma, Mohan RABSTRACT Introduction: Traumatic brain injury (TBI) is one of the significant causes of disability and death. It is a common cause of emergency neurosurgical consultation. Due to differences in physiology and management strategy, outcomes of pediatric TBI are different. This study purposes to describe the demography, clinical-radiological characteristics, and outcome of patients with pediatric TBI. Methods: A retrospective study of 112 children of age up to 18 years admitted to the Neurosurgical Department in Tribhuvan University Teaching Hospital following TBI from August 2021 to July 2022 was conducted. Variables analyzed were the demographics, clinical characteristics, imaging findings, management strategies, and outcome. Results: Median age was 5.5 years. The male-to-female ratio was 2.3:1. Falls followed by road accidents (RTA) were the most common mode of injury. A significant number of patients (62, 55.3%) presented after 24 hours of injury. Vomiting (67, 59.8%) was the commonest symptom followed by loss of consciousness (60, 53.6%). Post-traumatic seizure was observed in 13 (11.6%) of the children; however, had no association with the outcome. Mild, moderate, and severe TBI were seen in 80.3%, 17.8%, and 1.7% respectively. Extra-axial hematomas (40%) were the most common findings followed by skull fractures (33.9%). Intensive care was required in 13 (11.6%) and 34 (30%) required surgery. Craniotomy (30.3%) was the most common procedure. Good outcome at discharge was seen in 107 (95.5%) of patients. Conclusion: Falls and RTAs were the commonest causes of pediatric TBI. In our study, a significant number of the patients presented after 24 hours of injury. Craniotomy was the most common managment and most of the children had good outcomes at discharge.

There is still uncertainty regarding the usefulness of intraoperative neuromonitoring (IONM) during spinal surgery. The purpose of this study is to determine the effectiveness of IONM in patients undergoing intramedullary spinal surgery. Methods: Twenty-three patients who underwent surgery at the Department of Neurosurgery, Tribhuvan University Teaching Hospital from January 2017 to December 2020 were included. Somatosensory evoked potential, transcranial motor evoked potentials and electromyography were recorded. Patients were divided into three groups based on IONM parameters: 1. one with no drop 2. one with a decrease and a recovery during surgery, and 3. one with a decrease but no recovery. The duration of follow-up was six months. Results: Neurological improvement was noted in 14 patients, stable in 4, and worse in 5. Out of 14 patients with clinical improvement, 9 had no decrease in IONM, while 5 had a temporary decrease. Among 4 patients whose postoperative status remained unchanged, 2 had no decrease in IONM, while one had a temporary decrease and one has a sustained decrease. Among 5 patients who deteriorated postoperatively, 1 had no decrease in IONM, and 4 had a decrease without recovery. During surgery, patients who demonstrated monitoring alterations but reverted to baseline had better neurological outcomes than those who did not (p=0.045). Conclusion: Our findings support that IONM is an effective tool for the safe resection of IMSCL. Further multi-centric larger studies are recommended to gain more insight into IONM.

When they get appropriate care, long term result is generally good provided the patient receives good neurosurgical, paediatric and rehabilitation care. Surgery is the mainstay of treatment. Our aim was to analyze immediate and long-term results of lipomeningomyelocele repair in symptomatic patients presenting to TU Teaching Hospital, Kathmandu, Nepal. Methods Thirteen patients admitted to Department of Neurosurgery from January 2017 to December 2018 were evaluated. All patients underwent MRI of whole spine before surgery. Surgical procedures involved total excision of lipoma and repair in 10 patients and subtotal excision and repair in 3 patients. Division of filum terminale could be done in 8 patients. Follow up varied from 6 months to 2 years. Results This study included 8(61.5 %) patients of lumbosacral LMM, 3(23%) patients of sacral LMM and 2( 15.38%) patients of thoracolumbar LMM . About 2 (15.38%) were operated before 3 months of age, 2 (15.38%) were operated between 3-6 months of age, 5 (38.46%) were operated between 6-12 months of age and 4 (30.7%) were operated after 1 year. All children except one presented with lump on back since birth and four presented with urinary incontinence, one presented with bilateral club foot. Four (30.7%) patients had weakness of one or both lower limbs. Two (15.38%) patients had improvement in urinary incontinence, two unchanged and one had developed urinary incontinence postoperatively. Four children with had weakness of lower limbs; one patient improved whereas three patients did not improve postoperatively. There was no development of postoperative hydrocephalus after LMM repair. Three (23%) patients developed wound infection who responded well with regular dressings and antibiotics. Conclusion Lipomeningomyelocele repair can be done with satisfactory outcome with total excision of lipoma and division of filum terminale. Patients with residual lipoma and undivided filum terminale should be observed closely for the development of progressive neurological deterioration.

It results in a dramatic improvement in patient survival and neurological function but is associated with several complications requiring multiple shunt revisions throughout a patient’s lifetime. The main aim of the study was to evaluate the outcome especially complications of shunt surgery at our center. Methods: A single-institutional, retrospective observational study was conducted in 60 operated cases of congenital hydrocephalus with a minimum follow-up for up to 6 months. Parameters for analysis included demographic data, etiology of hydrocephalus, surgery time, and type of complications. Results: Out of 86 patients, 60 patients who fulfilled the inclusion criteria were enrolled in the study. The mean age of the patients at the time of VP shunt placement was 3 months, range from 8 days to 15 years with male preponderance. The majority of the patients belonged to the 0-1-year age group (76.8%). The commonest etiology of hydrocephalus was congenital aqueduct stenosis. Fifteen patients (25%) developed complications within six months follow-up period. Eight patients (13.3%) developed clinical shunt infection with four cases having culture positive. Four (6.67%) had mechanical complications in the form of shunt obstruction. Three patients had ascites, subdural collection, and shunt extrusion from the anus. The shunt related mortality was 1.67%. Conclusion: The shunt infection and obstruction still remain the most important complications. Despite inherent problems, shunt surgery is the procedure of choice until a safer effective alternative is available.

It increases the burden to the family and society. This study describes diseases related to spine and spinal cord from a neurosurgical department of a tertiary hospital in Nepal. Methods: This is a retrospective study of all spinal cases admitted between April 2019 to February 2019, in the Department of Neurosurgery, Tribhuvan University Teaching Hospital, Kathmandu, Nepal. All adult patients of ≥16 years, diagnosed with various spinal diseases were included. Based on the spectrum of causative pathologies, the study population was broadly categorized into trauma, degenerative, tumor, vascular and infection. Demographics, other variables, and outcome at 1 month were assessed. Results: A total of 71 patients were included in this study. Male preponderance was observed in all categories. Twenty three patients (32.4%) had traumatic spine injury and fall from height was the most common mode of injury, accounting for two-third of the total spinal trauma patients. Cervical segment was involved in two-third patients. More than one-third of the spinal patients (36.6%) had a degenerative disorder involving lumbar (57.7%) and cervical regions (42.3%). Spinal infection was diagnosed in 11.2% of the patients with 62.5% diagnosed as Pott’s spine. Overall complications were seen in 20%. Pain improved in all patients while overall good outcome was noted in 63.2% of the patients. Conclusion: Our study demonstrated a large patient burden and a clinical profile dominated by preventable causes such as RTA and fall injury. With early treatment and rehabilitation, significant improvement can be achieved. Further large scale multicenter studies are required to generalize the findings of this study to the whole population of Nepal. Keywords: Burden, Nepal, spine trauma, spine pathology
