Morel-Lavallée lesion of the lumbosacral region: A rare case report and comprehensive review of the literature.

The presentation of a Morel-Lavallée lesion in the lumbosacral region following a road traffic accident is an uncommon clinical entity. Knowledge of this rare site of occurrence can help in early diagnosis and proper management.

Aneurysmal Bone Cysts of Spine: An Enigmatic Entity.

AIMS: The study was done to review the literature about the intriguing aspects of the aneurysmal bone cyst and to describe our experience with these cases. DESIGN: Retrospective. MATERIAL AND METHOD: We reviewed the records of all patients with primary spinal tumours whom we managed over last 8 years. We selected the patients with biopsy proven aneurysmal bone cyst (ABC) for our study. RESULTS: Four patients (two males and two females) were included. The age ranged from 15-18 years. Three of them had neurological deficits and one had only pain. All of them were operated and three required instrumentation for stabilization. Neurological deficits improved in all the cases. However we had to re- operate one of the cases for recurrence and that patient was administered adjuvant radiotherapy. CONCLUSIONS: ABC is not a tumour in real sense but due to destructive nature that are classified as tumours. The patients have an excellent outcome as the disease is benign and has very low recurrence rates if surgical excision is complete. Best treatment modality is complete excision. Aneurysmal bone cyst is one of the uncommon tumors of the spine, and many of its features continue to be unclear even today. There is ambiguity about the definition, etiopathogenesis, radiological characteristics, histopathology and treatment modalities. They are common in young age and etiology is not clear. The presentation is varied with pain being the common symptom and neurological deficit depends on extent of cord involvement. The best treatment is controversial although surgery is believed to be curative in the majority of cases. We here describe our experience with four such cases who had varied clinical presentation and outcome.

Endoscopic Third Ventriculostomy in Noncommunicating Hydrocephalus: Report on a Short Series of 53 Children.

INTRODUCTION: Endoscopoic third ventriculostomy (ETV) is currently considered the best alternative to cerebrospinal fluid (CSF) shunt systems in the treatment of obstructive hydrocephalus. The aim of ETV is to communicate the third ventricle with the interpendicular cistern and create CSF flow which bypasses an obstruction to the circulation of the CSF. AIMS AND OBJECTIVES: The purpose of this study was to elucidate the indications, efficacy, safety and outcome Of ETV pediatric patients of noncommunicating hydrocephalus. MATERIAL AND METHODS: This study is a 3 year prospective study from June 2012 to May 2015. Records were kept for age, gender, etilogical factors, symptoms, signs, previous use of shunt or external ventricular device, imaging findings, and surgical complications (intraoperative and postoperative). Only those patients with age between 6months and 18 years with symptoms of intracranial hypertension and radiographic evidence of noncommunicating hydrocephalus were included in the study. RESULTS: A total of 53 patients were studied, out of these 29 were boys and 24 were girls. The mean age of the patients was 6.6 years. Overall a total of 50 successful ETVs were done in 53 patients. The success rate is estimated to be 94%. There was no mortality. The average postoperative hospital stay was 4 days. The followup ranged from 6 to 16 months (mean, 12 months). CONCLUSION: ETV in children is a safe, simple and effective treatment and a logical alternative to shunting procedure for patients of noncommunicating hydrocephalus.

Our Experience with Management and Outcome of Isolated Traumatic Brain Injury Patients Admitted in Intensive Care Unit.

INTRODUCTION: Traumatic brain injury (TBI) is a major cause of death and disability throughout the world. Commonly used predictors of outcome both individually or in combination include age, Glasgow Coma Scale score, pupillary reactivity, early hypoxia, and hypotension. Most of the studies previously done to examine risk factors for mortality in severe TBI were done in the setting of polytrauma. AIMS AND OBJECTIVES: The aim and objective of this study was to do an in-depth analysis of various factors associated with the management and outcome of patients with isolated TBI admitted in an Intensive Care Unit (ICU). MATERIALS AND METHODS: A total of seventy adult patients who were admitted to Intensive Critical Care Unit (ICU) with isolated TBI were selected during a 12-month period from January 2016 to December 2016. This is a prospective analytical study and parameters studied included age, sex, cause of admission classified by type of trauma, premorbid functional status, acute and chronic comorbidities, brain noncontrast computed tomography scan data, Glasgow Coma Scale (GCS), hemodynamic status, respiratory status, and mechanical ventilation, blood gases, serum electrolytes, serum glucose, hemoglobin, leukocyte and platelet counts, renal function, and urinary output. RESULTS: The study population consisted of 46 (65.7%) males and 24 (34.2%) females. The mean age was 35.5 years (range, 18-65 years). The most common mode of trauma was road traffic accident (43.6%) followed by fall from height (35.7%). Statistically insignificant relationship (P < 0.05) was seen with sex and mode of injury among survivors and nonsurvivors; however, 61.9% of patients with age ≥40 years died (P < 0.005). Among clinical parameters at admission to ICU, low GCS, hypotension (mean arterial pressure ≤80 mmHg), hypoxia (pO2 ≤60 mmHg, spO2 ≤90 mmHg), and nonreacting pupils were significantly associated with increased mortality (P < 0.05). CONCLUSION: Isolated TBI still continues to have a good amount of morbidity and mortality which perhaps can be reduced by strict adherence to guidelines of management.

Evaluation of Role of Electrophysiological Studies in Patients with Lumbar Disc Disease.

BACKGROUND: The role of the electrophysiologic studies in peripheral nerves and muscles of lower limbs (including paraspinal muscles) in prolapsed lumbar intervertebral discs has been studied with equivocal results. Pre- and post-operative electrodiagnostic studies have not been compared much. AIMS AND OBJECTIVES: To study the role of the electrophysiologic studies in prolapsed lumbar/lumbosacral intervertebral discs for finding the association between clinical findings and electrophysiological changes and to compare the electrophysiologic studies pre- and post-operatively. MATERIALS AND METHODS: The study was conducted from July 2014 to June 2016 on fifty patients who were admitted in the department of neurological surgery with lumbar disc prolapse and all these patients were subjected to surgery. Both pre- and post-operative (from 1 to 6 months after surgery) electrophysiological studies were conducted and compared. RESULTS: As per the electromyographic (EMG) abnormalities, the most common levels of intervertebral disc prolapse were L4-L5 and L5-S1 accounting for 32% of cases each followed by L5-S1 level which was seen in 28% of patients with L2-L3, L3-L4, and L4-L5 prolapsed intervertebral disc (PIVD) and L3-L4 and L4-L5 PIVD were seen in 4% of cases each. Of the 50 patients, EMG findings correlated with operative findings in 37 (74%) patients, however operative findings did not correlate with EMG findings in 13 (26%) patients. CONCLUSION: In compressive lesions of nerve roots (due to disc prolapsed), the EMG method has a high degree of accuracy in determining not only the presence of such lesions but also their exact location. EMG is accurate when correlated with the operative findings.

Osteoporosis Presenting as Low Backache: An Entity not Uncommon to be Missed.

INTRODUCTION: Low backache (LBA) is highly prevalent in osteoporotic patients and affects their quality of life. Overall, osteoporosis incidence is greater in females than in males, and osteoporotic fractures typically occur with only modest or moderate trauma. AIMS AND OBJECTIVES: To evaluate osteoporosis as a cause of LBA in patients attending a neurosurgical outpatient department and to study various risk factors associated with it. MATERIALS AND METHODS: The study entitled "Osteoporosis presenting as LBA: An entity not uncommon to be missed" was a 2-year hospital-based study conducted from August 2014 to July 2016 in a prospective manner and included 100 patients of osteoporosis with LBA. Analysis of records included their chief complaints, signs and symptoms, diagnostic investigations performed, treatment modalities they underwent, and further recommended management carried on them. RESULTS: Out of total 100 patients evaluated, 33 (33%) were male and 67 (67%) were female; the age of patients was in the range of 35-70 years (mean 56.54 ± 91). The number of patients with a significant medical or surgical history was 31 (31%). The history of drug intake such as thyroxine, steroids, and antiepileptics was present in a total of 11 patients out of which 10 were female and one was male. Regarding lifestyle characteristics of studied patients, a total number of 72 (72%) were having sedentary habits with 15 (45.5%) males and 57 (85.1) females, the total number of moderate workers was 19 (27.3) males and 10 (14.9%) females, and heavy workers were 9 (9%) with 9 (27.3) males and 0 (0%) female. CONCLUSION: LBA is highly prevalent in osteoporotic patients especially in women. The incidence of osteoporosis and LBA increased with low body mass index, increasing age, and duration of menopause. The various risk factors for osteoporosis include smoking, history of medical diseases such as diabetes mellitus, history of hysterectomy, and history of antiepileptic, thyroxine, and steroid intake.

Spinal angiolipoma mimicking a schwannoma: A case report.

BACKGROUND: Angiolipomas rarely involve the spinal canal/foramina, and may prove difficult to differentiate from schwannomas. CASE DESCRIPTION: Here we report a patient who presented with a spinal angiolipoma contributing to spinal cord and neural foraminal compression that was difficult to differentiate from a schwannoma. CONCLUSION: Spinal angiolipomas rarely involve the spinal canal/foramina. Utilizing neurodiagnostic studies with pathological confirmation, these lesions may be differentiated from schwannomas.

Coccygectomy for Coccygodynia: A Single Center Experience Over 5 Years.

INTRODUCTION: Coccygodynia refers to a pathological condition in which pain occurs in the coccyx or its immediate vicinity. The pain is usually provoked by sitting or rising from sitting. Several studies have reported good or excellent results after coccygectomy especially in patients who are refractory to conservative treatment. AIMS AND OBJECTIVES: This study aims to evaluate the role and effectiveness of coccygectomy in chronic refractory coccygodynia. MATERIALS AND METHODS: Between January 2011 and January 2015, 16 consecutive patients (4 males and 12 females) who underwent surgical coccygectomy were enrolled prospectively in the study. All patients suffered from treatment-resistant coccygodynia and had exhausted conservative therapeutic options for at least 6 months before undergoing surgery. The same surgeon performed a complete coccygectomy on all patients. Postoperative outcomes included measurements of pain relief and degree of patient satisfaction with the procedure's results. RESULTS: The average age of patient was 37.93 years (range: 25-53 years), and the male to female ratio was 1:3. The median duration of patient-reported symptoms prior to surgery was 24 months. The most common cause of coccygodynia was direct or indirect trauma, recorded in 11 patients (68.75%). Idiopathic coccygodynia was five cases (31.25%). The number of patients with outcomes rated as "excellent," "good," "fair," and "poor" were 12, 2, 1, and 1, respectively. The favorable result (excellent or good) was 87.5%. The self-reported visual analog scale (VAS) was significantly improved by surgery. The mean VAS preoperatively was 9.62, and postoperatively it was 2.25 (P < 0.001). There were two infections (12.5%) among the 16 patients which were managed conservatively. CONCLUSIONS: Coccygectomy for chronic intractable coccygodynia is simple and effective, with a low complication rate.

Profile of High Grade Gliomas - A Single Center Experience.

INTRODUCTION: The term high grade glioma (HGG), is usually used to describe WHO grade III and IV tumours. There has been a recent increase in incidence of HGGs in the Western world, particularly in the elderly population. This probably reflects the easy availability of vastly improved diagnostic imaging. A five year retroprospective study was planned to study demography, clinical presentation, imaging, surgical intervention, histopathological examination of specimens and postoperative outcome of patients of high grade gliomas. OBJECTIVES: To determine the demographic, clinical, histopathogical and radiological profile of patients of High Grade Gliomas (HGG) and to ascertain post-operative mortality at 24 hours and 7 days Material and Methods: The present study of 226 cases from our institute for the last 5 years (retrospective 3 years and prospective 2 years) extending from August 2010 to July 2015 is based on study about demography, clinical presentation, imaging, surgical intervention, histopathological examination of specimens and postoperative outcome. The clinic-pathological vis-a-vis imaging was also studied. The analyzed data from the results and observations of this study were compared with the previous studies. RESULTS: The study was retrospective as well as prospective. Total of 226 patients were registered. Out of these, 225 patients were operated (except one patient). The provisional diagnosis was based on the radio-imaging basis and the final diagnosis confirmed by histopathological examination. Majority of patients operated for HGG, irrespective of the procedure or extent of resection had good surgical outcome after the procedure. CONCLUSION: The overall survival is multifactorial in HGGs. The surgical intervention particularly in patients with features of raised ICP due to mass lesion provides symptomatic relief and improves quality of life in majority of patients and are discharged reasonably in better state of health.

A Unique Case of Primary Intracranial Melanoma.

Primary intracranial melanoma is an uncommon entity and only case reports have been published in the literature. We report a case of an elderly male who was operated with a preliminary diagnosis of meningioma, but it proved to be a histological surprise as it came out to be melanoma with no primary anywhere in the body.

Cranioplasty: Indications, procedures, and outcome - An institutional experience.

BACKGROUND: Cranioplasty, the repair of a skull vault defect by insertion of an object (bone or nonbiological materials such as metal or plastic plates), is a well-known procedure in modern neurosurgery. Brain protection and cosmetic aspects are the major indications of cranioplasty. A retroprospective study was conducted for evaluating the indications, materials used, complications, and outcome of cranioplasty. METHODS: This study was prospective from August 2013 to September 2015 and retrospective from August 2010 to July 2013. In the retrospective study, patients files were retrieved from the mentioned date (August 2010 to July 2013) from the medical records and the findings were recorded. Abstracted data included age at the time of cranioplasty (years), sex (male or female), medical comorbidities (hypertension, diabetes), indications for craniectomy [Road traffic accident (RTA), fall from height (FFH), hit by stone or cricket ball, physical assault, stroke, infection, shell injury, bullet injury, and intraoperative swelling], laterality of cranioplasty (bilateral, unilateral, or bifrontal), time between craniectomy and cranioplasty (weeks), type of graft (autologous or artificial), type of prosthesis if used (methylmethacrylate, titanium), storage of bone flap if used (subcutaneous or deep freezer), operative time (minutes), and complications fallowing cranioplasty. RESULTS: Of the 236 patients included in the study, maximum were in the age group of 21-30 years i.e., 30.93% (n = 73). Mean age of the patients was 33.44 years. A total of 196 (83.05%) were autologous and 40 (16.95%) were artificial. Out of the 40 patients who underwent artificial cranioplasty, 36 (15.25%) had methylmethacrylate graft and 4 (1.7%) had titanium mesh implant. Bone was not preserved in 16.95% (n = 40), preserved in subcutaneous tissue in abdominal wall in 2.54% (n = 6), and preserved in deep freezer in 80.51% (n = 190) of the patients. CONCLUSION: Cranioplasty as a procedure is not without complications; however, if performed properly and at proper time with an aseptic technique, good results are achieved.

Pediatric Head Injury: A Study of 403 Cases in a Tertiary Care Hospital in a Developing Country.

INTRODUCTION: Traumatic brain injury (TBI) in children is a significant cause of morbidity and mortality worldwide. Falls are the most common type of injury, followed by motor vehicle-related accidents and child abuse. AIMS AND OBJECTIVES: The aim and objective of this study was to elucidate the various modes of injury, prognostic factors, complications, incidence of various modes of injury, and outcome in TBI in pediatric population. MATERIALS AND METHODS: Patients with TBI, 18 years or less in age, managed in our Department of Neurosurgery, over a period of 2 years, were studied prospectively. Detailed history, general physical examination, systemic examination, and central nervous system examination including assessment of Glasgow Coma Scale score (GCS) and pupillary size and reaction were noted in every patient. Based on GCS, patients were divided into mild head injury (GCS 13-15), moderate head injury (GCS 9-12), and severe head injury (GCS ≤8) categories. All the patients were subjected to plain computed tomography (CT) scan head, and CT findings were noted. Patients were managed conservatively or surgically as per the standard indications. The outcome of all these patients was assessed by Glasgow outcome scale and divided into good (normal, moderate disability) and poor (severe, vegetative, dead) outcome. Outcome was assessed in relation to age, sex, GCS, pupil size and reaction, CT scan features, intervention, and associated injuries. RESULTS: A total of 403 patients aged between 1 day and 18 years were included in the study comprising 252 males (63%) and 151 females (37.75%). The common modes of injury were fall 228 (56.6%) followed by road traffic accidents 138 (34.2%), assault 10 (2.5%), and others 27 (6.7%) which include sports injury, hit by some object on head, and firearm injury. Majority of our patients had a GCS of 13-15 (mild head injury), 229 (57.3%), followed by 9-12 (moderate head injury) 119 (29.8%), followed by 8 or less (severe head injury) 52 (13%). In group of patients in the category of GCS ≤ 8, poor outcome was seen in 65.3%, followed by patients in group GCS 9-12 at 2.45% succeeded by group of patients with GCS 13-15 at 2.6%, which was statistically significant (P < 0.0001). A total of 354 (87.8%) patients had normal pupils, 37 (9.2%) had anisocoria, and 12 (3%) patients had fixed dilated pupils. Fixed dilated pupil had poor outcome (100%) followed by anisocoria (40.5%) and normal pupils (16%), which was statistically significant (P < 0.0001). CONCLUSION: Majority of children who suffer from TBI do well although it still continues to be a significant cause of morbidity and mortality in them. The outcome is directly related to the neurological status in which they present to the hospital.

Epidemiology of the neural tube defects in Kashmir Valley.

INTRODUCTION/BACKGROUND: Neural tube defects (NTD) are the most common congenital malformations affecting the brain and spinal cord and have a multifactorial etiology. Genetic and environmental factors have been found to cause these defects, both individually and in combination. AIMS AND OBJECTIVES: The aim of this study was to determine the incidence, types, demographics, risk factors, and other associated anomalies relevant to NTDs in Kashmir Valley. MATERIALS AND METHODS: A 2-year hospital-based prospective study was carried out from November 2013 to October 2015. A detailed history of the mother was taken along with detailed clinical examination of neonate including measurement of head circumference and checking the status of fontanella, whether - lax/full/bulging/or tense, type of NTD. Investigations that were done included were X-ray skull: Anteroposterior (AP) and lateral, X-ray spine: AP and lateral, ultrasonography abdomen, magnetic resonance imaging: Spine and brain. RESULTS: The total number of babies with NTD's was 125 with an overall incidence of 0.503. District Kupwara was having the highest incidence (1.047) and district Srinagar the lowest incidence of NTD's (0.197). The majority of NTD's (116 cases, 92.8%) were found in the rural areas. Among the different types of NTD's, spina bifida had an incidence of 0.342 (85 cases, 68%), and anencephaly had an incidence of 0.113 (28 cases, 22.4%). There was a slight preponderance of females over males with NTD's. There were70 females (56%) and 55 males (44%) respectively with a male:female ratio of 0.8:1. CONCLUSIONS: The incidence rates of NTDs are very high for Kashmir Valley. Geographical distribution of NTDs at this place confirms a relationship between the socioeconomic status, educational status, maternal age and environmental factors for the development of an NTD. The results of this study point to the importance establishing a health policy to prevent NTDs in Kashmir Valley.

A unique case of calvarial hemangioma.

BACKGROUND: Calvarial hemangiomas are one of the rarest neoplasms affecting the skull, predominantly occurring in parietal and frontal bones. CASE DESCRIPTION: We report a parietal hemangioma in a middle-aged female which presented as a painless swelling that was progressively increasing in size and was treated surgically. CONCLUSION: Although rare, calvarial hemangioma should be a part of the differential diagnosis of calvarial swellings.

CONCLUSIONS: The incidence rates of NTDs is very high for Kashmir Valley. Geographical distribution of NTDs at this place confirms a relationship between the socioeconomic status, educational status, maternal too young or advanced age, and environmental factors for the development of a NTD. The results of this study point to the importance establishing a health policy to prevent NTD in Kashmir Valley.

Metastatic Ameloblastoma to Brain: A Rare Entity.

Ameloblastoma is a rare odontogenic tumor of the jaw. It is a benign neoplasm but local recurrence is common. Metastasis from this tumor is all the more rare. The commonest site for metastasis is lung. Brain is a very uncommon site of involvement. Overall prognosis is good. We hereby discuss ameloblastoma of lower jaw in a young adult which had metastasized to brain. Patient was operated for the metastatic lesion of brain and is doing well on follow-up.

Role of external ventricular drainage in the management of intraventricular hemorrhage; its complications and management.

BACKGROUND: External ventricular drainage (EVD) is the procedure of choice for the treatment of acute hydrocephalus and increased intracranial pressure in patients of subarachnoid hemorrhage (SAH) and intracerebral hemorrhage with hydrocephalus and its sequelae. We evaluated the use of EVD in patients of SAHs (spontaneous/posttraumatic with/without hydrocephalus), hypertensive intracerebral bleeds with interventricular extensions, along with evaluation of the frequency of occurrence of complications of the procedure, infectious and noninfectious, and their management. METHODS: During the period of 2½ years, between September 2012 and February 2015, 130 patients were subjected to external drainage procedure and were prospectively enrolled in this study. Information was collected on each patient regarding age, sex, diagnosis, underlying illness, secondary complications, other coexisting infections, use of systemic steroids, antibiotic treatment (systemic and intraventricular), and whether any other neurosurgical procedures were performed within 2 weeks of EVD insertion or any time the duration of ventriculostomy. RESULTS: The study population of 130 patients underwent a total of 193 ventriculostomies. Thirty-six patients had ventriculostomy infection (27.6%). Evaluation of the use of EVD was done by comparing preoperative and postoperative grading scores. Forty-nine patients survived and improved their score from Grade 3-5 to Grade 2-4. Twenty-nine patients were moderately disable, 16 were severely disable, and 5 were left in the vegetative state. Evaluation of outcome of patients revealed that there was an overall mortality of 61 (46.9%) patients both in the acute phase and later. 33 of the 39 patients having Glasgow Coma Score (GCS) 3-5 at the time of EVD insertion expired, as against 20 of the 51 patients in GCS 6-8. Patients in GCS 9-12 had an even better outcome, with 8 of the 35 patients in this group expiring. CONCLUSIONS: The use of EVD should be undertaken only in situation where it is absolutely necessary and ventriculostomy should be kept only for the duration required, and this should be monitored on a daily basis, given the exponential increase in infection after 5 days.
