Solitary Skull Langerhans Cell Histiocytosis Presenting With a Pus Draining Fistula: An Unusual Presentation and Review of Literature.

Langerhans cell histiocytosis (LCH) is a rare condition in adults, especially when it is limited to a single area of the skull, known as solitary calvarial involvement. In this case report, we present a unique instance of LCH affecting the parietal bone with a pus-draining fistula. This is a rare and unusual presentation at this location, which has been scarcely reported in medical literature. A 30-year-old woman with no prior comorbidity presented with complaints of headache that persisted for a year. She also had swelling on her scalp and a yellowish discharge for 3 weeks, but no neurological problems were observed. Radiology revealed thinning of the calvaria, with ragged margins along the inner table, multiple focal erosions, and involvement of overlying soft tissue and bony sequestrum. The patient underwent biparietal craniotomy and excision of the lesion. The histopathology report showed LCH. After 8 months of follow-up, there was no recurrence. The management of solitary calvarial involvement by LCH with masquerading presentation as a scalp infection can be achieved through complete excision of the lesions, resulting in a favorable outcome.

Comparing redo surgery and stereotactic radiosurgery for recurrent, residual, and/or tumors showing progression in nonfunctioning pituitary adenomas: A systematic review and meta-analysis.

Background: Non-functioning pituitary adenomas (NFPAs) are well-differentiated benign tumors originating from the adenohypophyseal cells of the pituitary gland. They present with headaches, visual disorders, or cranial nerve deficits. NFPAs can recur, progress, or present as residual tumors. We, therefore, conducted this review to compare the effects of both revision surgery and stereotactic surgery on tumor size, visual status, endocrine status, and complications. Methods: A systematic review of published literature on recurrent, residual, or progressing NFPAs that underwent redo surgery or stereotactic radiosurgery from the inception till June 2020 was conducted as per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Thirteen records (1209 patients) were included, and risk ratio (RR) and 95% confidence intervals (CIs) estimated from each study were pooled using a random-effects meta-analysis model. Results: Redo surgery was the preferred intervention in patients presenting with larger tumor sizes and was more effective in reducing the tumor size as compared to stereotactic radiosurgery (SRS) (risk ratio [RR] 56.14; 95% CI, 16.45-191.58). There was more visual loss with revision surgery as compared to SRS (risk ratio [RR] 0.08; 95% CI, 0.03-0.20). However, SRS was associated with fewer complications, such as new diabetes insipidus, as compared to the redo surgery (risk ratio [RR] 0.01; 95% CI 0.01-0.03). Conclusion: Redo surgery is the superior choice in the treatment of recurrent/residual or progressing NFPAs if the tumor size is large and an immediate reduction in tumor burden through debulking is warranted. However, redo surgery is associated with a higher risk of visual loss, new endocrinopathies, and other complications, in contrast to SRS.

Endocrine Abnormalities in Children With Traumatic Brain Injury at a Tertiary Care Center.

Objective Accidental traumatic brain injury (TBI) can lead to severe complications such as endocrine abnormalities and long-term morbidities and can negatively impact patient lives. These conditions are also associated with a high cost of treatment over a lifetime, a significant concern in low-to-middle-income countries (LMICs). In Pakistan, the prevalence of children with endocrine abnormalities secondary to TBI remains largely unexplored. We conducted a retrospective cross-sectional study to estimate the burden of endocrine abnormalities due to TBI among children in our population. Methods Twenty patients previously admitted with head injury between September and October 2019 were retrospectively reviewed with tests for baseline serum sodium, plasma osmolality, cortisol, adrenocorticotropin (ACTH), free thyroxine (fT4), growth hormone (GH), insulin growth factor-1 (IGF-1), follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid-stimulating hormone (TSH), prolactin, estradiol, and testosterone. Data were collated from the electronic Health and Information Management System (HIMS) and analyzed using SPSS v25. Chi-square and t-tests were used to identify associations between variable groups. Outcomes of interest included correlations between hormonal levels and demographic factors, interventions and hormonal levels, and complication rates and hormonal levels. Results Our study reports three (15% of the total cohort) patients with pituitary hormone deficits (two with low IGF-1 and one with low TSH). High serum IGF-1 and ACTH levels were also observed in three (15%) children. High IGF-1 was associated with female gender (p=0.007), mechanical ventilation (p=0.038), and falls (p=0.028). IGF-1 (p=0.035) and GH (p=0.049) levels were associated with improvement in Extended Glasgow Outcome Scale (GOS-E) score. Testosterone was positively correlated with a high percentile for height (p=0.005) and GOS-E scores on follow-up (p=0.030). High testosterone levels (592.12 ± 102.28 ng/dl) were associated with good functional outcomes in post-pubescent patients (p<0.05). Serum fT4 was linked with a high GOS-E score at discharge in prepubescent patients (p=0.034). Neurosurgical decompression was the only risk factor for hormone deficiency, comprising 67% of the group with hormone deficiencies (p=0.028). The learning difficulties were observed exclusively in children with hormonal deficiencies (7 patients, p=0.000).  Conclusion Hormonal dysfunction due to TBI in children can lead to poor outcomes. High serum IGF-1, testosterone, and free T4 levels were associated with improved functional outcomes in children with TBI. Limited follow-up and resources in LMICs are significant barriers to addressing the morbidity associated with these conditions and need to be addressed at a health policy level.

Mature teratoma of the cisterna magna in an adult patient.

Background: Teratomas are a rare subgroup of CNS germ cell tumors and are histologically classified into mature teratomas, immature teratomas, and teratomas with malignant transformation. CNS teratomas are infrequently found in the posterior fossa and pure mature teratomas of posterior fossa are rare especially in adults. We present a case of a young adult female with a mature teratoma in the cisterna magna. Case Description: A 26-year-old female presented to the neurosurgery clinic with headache, nausea and vomiting for the past 1 year. She was found to have dysdiadochokinesia on neurological examination. Brain magnetic resonance imaging scan showed a-well defined lesion, hyperintense on T1 and hypointense on T2-weighted sequences located within the cisterna magna. She underwent a suboccipital craniotomy with resection of lesion. Histopathology confirmed the diagnosis of mature cystic teratoma. Conclusion: Mature teratomas located in the posterior fossa among adults are rare in the literature. We report the second case of mature teratoma in the cisterna magna of an adult patient.

Prepontine intracerebral cyst with spontaneous resolution.

BACKGROUND: Intracranial cysts in the prepontine region are rare and can lead to various complications if not managed appropriately. Symptomatic prepontine cysts may require surgical intervention. However, spontaneous resolution of such cysts is rarely reported in literature. CASE DESCRIPTION: We describe the case of a middle-aged lady who presented with headaches and imbalance, with no focal neurological deficits on examination. Magnetic resonance imaging (MRI) of the brain showed a prepontine cyst compressing the brainstem with craniocaudal extension through the foramen magnum. The patient was given symptomatic treatment and followed closely with repeat MRI scans. These scans showed regression and eventual disappearance of the lesion, with complete resolution of symptoms. CONCLUSION: In light of the few reported cases of spontaneous resolution of prepontine cysts, we highlight the possibility of these lesions to self-resolve.

Endovascular Management of Type III Perimedullary Spinal Arteriovenous Malformations in Pediatric Population.

BACKGROUND: Spinal arteriovenous malformations (AVMs) are a cause of 20-30 of all spinal vascular malformation. The treatment option for the AVM depends upon the type of AVM. Here, we present a case series to discuss the type, management, and post-operative conclusion of the spinal AVMs. METHOD: Four patients with spinal AVMs were retrospectively reviewed. All 4 patients were with a nidus-type AVM. Treatment for all patients required embolization. Clinical features, imaging, treatment, and clinical results were observed. All 4 patient's clinical outcome was assessed using the Modified Ranked Scale. RESULT: The follow-up after management showed that all four-patient recovered without any residual deficit. All four-patient scored zero (0) on the Modified Ranked Scale. CONCLUSION: Pediatric spinal AVMs are rare and require complex multimodal approach to achieve favorable outcomes.

Spinal cord hemangioblastomas with a focus on clinical presentation, diagnosis, and treatment at a tertiary care hospital of Karachi, Pakistan: A retrospective chart review.

BACKGROUND: Hemangioblastomas are benign neoplasms that consist of stromal cells and small blood vessels. They are highly vascular tumors and can arise throughout the central nervous system. This study aims to provide an overview of our experience with this rare tumor's presentation, radiology, histopathology, and outcomes as literature regarding this pathology is sparse from our country. METHODS: The study is a retrospective review of cases that were histopathology proven cases of spinal cord hemangioblastomas. The clinical characteristics of these patients were examined, and their presentation was recorded. The radiology was also reviewed to describe classic appearance on magnetic resonance imaging. A detailed review of immunohistochemistry was also performed and outcome was described. RESULTS: A total of 25 cases of spinal hemangioblastomas were found in our records in the period of 2001-2019. There were 20 males (80%) and only 5 female patients (20%). Gross tumor fragments ranged in size from 0.24 cm2 to 10.5 cm2 (mean 3.28 ± 2.65). Histologically, tumor was composed of nests of large stromal cells with clear to vacuolated cytoplasm separated by thin-walled capillaries. Focal intratumoral hemorrhage was noted. No significant cytological atypia or mitotic figures were noted. Immunohistochemical stains were performed to confirm the diagnosis and exclude other tumors. Inhibin was tested in 20 cases and it was positive in 16 cases (80%). Neuron-specific enolase was positive in 6/8 cases. Cluster of differentiation (CD) CD68 was positive in 6/6 cases and vimentin in 4/4 cases. Glial fibrillary acidic protein (GFAP) and epithelial membrane antigen were performed in 14 and 8 cases, respectively, and all were negative. Cytokeratin AE1/AE3 was negative in 13/13 cases. CD34 highlighted vasculature in the 8 cases in which it was performed and was negative in tumor cells. Follow-up was available in 17 out of 25 cases and ranged from 12 months to 216 months (mean 61.8 ± 60.6 months). Recurrence occurred in 2 out of 17 (11.7%) patients for whom follow-up information was available. CONCLUSION: Our experience shows that spinal cord hemangioblastomas can be surgically removed in most cases with a low risk of recurrence. Most patients in our study were male and unlike other studies, none of our cases showed GFAP positivity.

Arteriovenous malformation with associated multiple flow-related distal anterior cerebral artery aneurysms: A case report with poor outcomes.

BACKGROUND: Low-grade arteriovenous malformations (AVMs) associated with multiple flow-related distal anterior cerebral artery (DACA) aneurysms are rare occurrences. Here, we present a case of a frontal AVM with three associated DACA aneurysms arising from a single feeder. CASE DESCRIPTION: A 36-year-old male presented to us in the ER with acute-onset dysphasia and altered mental status. Head computed tomography and angiogram showed a spontaneous intracerebral hemorrhage with intraventricular extension and revealed a Spetzler Martin Grade II AVM, being fed by two feeders, with the major feeder from the DACA bearing three flow-related aneurysms. As the patient awaited digital subtraction angiography, his Glasgow Coma Scale dropped and he underwent emergency embolization with Onyx. This was followed by external ventricular drainage. The patient's neurological status did not improve, and he died following a complicated clinical course. CONCLUSION: Multiple DACA aneurysms are a case of both clinical and anatomical rarity and to avoid complications in the clinical course, one must be judicious about the time spent between symptom onset and embolization.

Work-life balance amongst residents in surgical and non-surgical specialties in a tertiary care hospital in Karachi.

OBJECTIVE: To assess work-life balance among medical residents at a tertiary hospital. METHODS: The cross-sectional study was conducted from September to December 2016 at a private-sector tertiary care hospital in Karachi, and comprised medical residents working at the facility. A standardised, self-administered questionnaire was developed on the basis of Canadian Mental Health quiz and a study in literature. The questions aimed at assessing satisfaction with work as well as emotional and personal life of residents in various medical and surgical specialties. SPSS 20 was used for data analysis. RESULTS: Of the 275 residents, 129(46.9%) were males and 146(53.1%) were females. The overall mean age was 28.19±2.194 years. Of the total, 13(4.7%) participants thought they had work-life balance; 165(60%) felt their job had negatively affected their private lives; 118(42.9%) felt worn out; 109(39.6%) expressed moderate dissatisfaction with work-related factors; 119(43.3%) were dissatisfied with life outside work; and 93(33.8%) were dissatisfied their health. CONCLUSIONS: There was minimal work-life balance among the residents.

Treatment options for paediatric brainstem gliomas.

Paediatric brainstem gliomas (BSGs) can be classified broadly into two distinct categories: focal brainstem gliomas (FBSGs) and diffuse intrinsic pontine gliomas (DIPG). The former account for 20% of paediatric BSGs and are mostly indolent lesions with good prognosis. DIPGs constitute the remaining 80%, and are highly aggressive, malignant tumours having a dismal prognosis; being the foremost cause of death in children with brain tumours. Their poor response to treatment regimens is further complicated by their localization in eloquent brainstem areas, thereby making it difficult to establish a standardized framework of therapeutic intervention. In this review, the authors catalogue and appraise current treatment modalities utilized in the management of paediatric BSGs including steroid use, chemotherapy, radiotherapy, and surgery.

Pre-operative Voriconazole in patients undergoing surgery for Central Nervous System fungal infections: Special Report.

Fungal infections of the central nervous system (CNS) are uncommon. Despite several advancements in diagnosis and treatment of these infections, the mortality rates remain high. The current retrospective study was planned to define the demographic and clinical features of patients with CNS fungal infections. Conducted at Aga Khan University Hospital, Karachi, and comprising CNS fungal infections operated between January 2000 and December 2015. The study analysed whether a short course of pre-operative anti-fungal therapy may improve outcomes in these patients. There were 47 cases confirmed on histopathology and/or microbiology. Outcome measures used were Glasgow coma score (GCS), Glasgow outcome score (GOS) and Karnofsky performance score (KPS). The overall 30-day mortality was 20(42.5%). Fungal infections of the CNS can occur in both immune-compromised and immune-competent patients. Early diagnosis, radical surgery, pre-operative anti-fungal therapy for at least 2 weeks, pre- and postoperative Voriconazole therapy results in more favourable outcomes.

Primary intracranial extraosseous Ewing's sarcoma.

INTRODUCTION: Common sites of occurrence of extraosseous Ewing's sarcoma include the soft tissues and bones of the lower extremity, 12 paravertebral, and retroperitoneal regions. Primary intracranial Ewing's sarcoma/pPNET is usually intraparenchymal located 13 when supratentorially, and an extraaxial epidural tumor radiographically mimicking a meningioma is extremely rare. CASE PRESENTATION: A 20-year14 old male presented to the emergency department with a 1-day history of drowsiness, headache, and fever. Neurological exam15 ination revealed decreased muscle strength (4/5) in the left lower limb. Head computed tomography scan showed an epidural 16 space-occupying lesion in the right temporoparietal region, which was assumed to be a meningioma by radiographic criteria. However, the surgical specimen was diagnosed as Ewing's sarcoma. CONCLUSION: Primary intracranial extraosseous Ewing's sarcoma is a rare condition that may mimic a meningioma on imaging. Physicians must be cognizant of this possibility, particularly in any young individual with a solitary contrast-enhancing dural-based lesion.

Outcome of Decompressive Craniectomy in Traumatic Closed Head Injury.

OBJECTIVE: The aim of the current study was to observe functional outcomes of patients undergoing decompressive craniectomy (DC) for raised intracranial pressure (ICP) after blunt head injury and to assess possible predictive factors. METHODOLOGY: This study was a prospective cohort study which was conducted at Aga Khan University Hospital, Karachi over a period of 2 years (January 2015-December 2016). Adult patients, aged between 15 and 65 years of both genders undergoing DC during the study period were selected. Outcomes of DC were assessed at an interval of 3 months following injury using the Glasgow outcome score. The data were analyzed on IBM statistics SPSS version 21. RESULTS: Seventy-two patients underwent DC for raised and refractory ICP. Glasgow Outcome Scale (GOS) at discharge, 1-month and 3-month follow-up were reported. GOS at 3-month follow-up showed 21 patients (29.2%) patients had a good recovery, moderate disability was reported in 16 patients (22.2%), and severe disability in 12 patients (16.7%), persistent vegetative state was seen in five patients (6.9%). Eighteen patients had in hospital mortality (25.0%). Tracheostomy and sphenoid fractures were found to be negative predictors of good functional outcome. CONCLUSIONS: DC is associated with an in hospital mortality of 25.0%. Favorable outcomes were seen in 51.4% patients. Tracheostomy and sphenoid fractures were negative predictors of good functional outcome. The results are comparable to international literature.

Factors Affecting Functional Outcome after Decompressive Craniectomy Performed for Traumatic Brain Injury: A Retrospective, Cross-sectional Study.

BACKGROUND: Factors affecting functional outcome after decompressive craniectomy (DC) performed for traumatic brain injury (TBI) remain poorly understood. METHODS: We conducted a retrospective study of all patients who underwent primary DC for TBI at our hospital between 2010 and 2014. Multivariate regression analyses were used to determine the predictors of functional outcome and overall survival. RESULTS: A total of 98 patients with severe (n = 81, 82.6%) or moderate (n = 17, 17.4%) TBI underwent primary DC and were included in this study. The 30-day and overall mortality rates were 15.3% and 25.5%, respectively. At a median follow-up of 90 (interquartile range (IQR): 38-180) days, median Karnofsky Performance Status (KPS) and Glasgow outcome scale-extended (GOSE) scores were 50 (IQR: 20-70) and 5 (IQR: 3-7), respectively. Young age and severe TBI were predictors of mortality. Glasgow coma scale (GCS) score on discharge was a strong predictor of KPS and GOSE scores. CONCLUSION: Primary DC afforded an acceptable functional outcome (GOSE score ≥5) in 45.9% of patients. Young age and lower GCS at presentation were associated with worse survival. GCS score on discharge was a strong predictor of functional outcome.

Biological characteristics and outcomes of Gliosarcoma.

Gliosarcoma is a highly aggressive primary brain tumour. It is a relatively rare tumour and comprises of two histological components, glial and sarcomatous. Gliosarcomas carry a poorer prognosis than that of Glioblastoma Multiforme (GBM). The current review highlights important histological and radiological features of gliosarcoma in the light of recent literature, and also touches upon the treatment options and outcomes of various types of gliosarcoma.

Prognostic Implications of Histological Clear Cells in High-Grade Intracranial Ependymal Tumors: A Retrospective Analysis from a Tertiary Care Hospital in Pakistan.

BACKGROUND: Clear cell variant in ependymal tumors is rare. We aimed to compare the features and outcome of the World Health Organization (WHO) Grade 3 ependymal tumors with clear cells to the WHO Grade 3 classic anaplastic ependymoma (AE). MATERIALS AND METHODS: A retrospective cohort study conducted at the Department of Neurosurgery, Aga Khan University, Pakistan, from 2003 to 2013. The medical records and radiology of patients with proven histopathology were reviewed. The analysis was done on SPSS 20. RESULTS: Nine cases of clear cell variant and 23 cases of classic AE were found, both of which combined equated to 4% of the total tumor burden in 11 years. The median age of clear cell ependymoma (CCE) and AE were 49 and 37 years, respectively. Presenting symptoms included headache in 66% of CCE and 63% in AE, raised intracranial pressure accounting for 33% of CCE and 54% of AE, dizziness in 22% CCE and 39% AE, while seizures presented equally in both. Supratentorial location was observed in 77% CCE and 48% AE. Both showed hypointense signals on T1-weighted images of magnetic resonance imaging (MRI) while T2-weighted images showed hyperintensity in all cases of CCE but only 80% of AE. MRI characteristics such as the presence of cystic component were found in 89% of CCE and 68% of AE, necrosis in 33% CCE, and 22% AE, hemorrhagic in 22% CCE and 9% AE, and equivalent contrast enhancement. Gross total resection was achieved in 5 (55%) patients of CCE, compared to 6 (26%) patients in AE. Subtotal resection was done in 4 (44%) patients of CCE and 15 (65%) patients of AE. Radiotherapy was given to 5 (55%) patients of CCE and 12 (52%) patients of AE. Recurrence was observed in 77% cases of CCE and 70% of AE, with metastasis in 29% of AE and in only one patient of CCE. Repeat surgery was done in 3 (33%) cases of CCE and 8 (35%) cases of AE. Median progression-free survival and overall survival were 9 and 13 months, respectively, in CCE while 14 and 18 months, respectively, for AE. CONCLUSION: Clear cells in the WHO Grade 3 ependymal tumors are found mainly in a comparatively older adult population with a predilection for supratentorial location and are more aggressive in behavior with poorer outcome than AE.

Preservation of Hearing and Facial Nerve Function with the Microsurgical Excision of Large Vestibular Schwannomas: Experience with the Retrosigmoid Approach.

Introduction Vestibular schwannomas (VS) are the most common benign neoplasms of a cerebellopontine angle (CPA), which arise from the Schwann cells of the vestibulocochlear nerve. Eighty percent of CPA tumors are VS followed by meningioma as the second common mass lesion in this critical potential space. Treatment options range from watchful waiting with serial imaging studies to radiosurgery or a microsurgical excision or a combination of surgery and radiation therapy. The primary objective of the study was to assess hearing and facial nerve status before and after the surgery via the retrosigmoid approach. Methods The database of Aga Khan University Hospital was searched for diagnoses of vestibular schwannomas between 2000 and 2007. A total of 35 patients were identified; among them, 27 were selected for the study who met the inclusion criteria. The variables of the study were age, gender, presenting symptoms, size of the tumor, surgical approach, hearing levels, and facial nerve function. Hearing loss was categorized according to the Gardener-Robertson hearing classification and the House-Brackmann Scale was used for facial nerve assessment. Results Out of the 27 patients, 18 were male and nine were female. The mean age was 43 years. The most common presenting complaint was hearing loss and tinnitus, seen in 21 patients. Headache was present in six patients, ataxia in five, and vertigo in three. Facial nerve weakness was noticed in six patients. Two patients had Grade-III paralysis, three had Grade-IV paralysis, and one had Grade-V paralysis. The audiogram confirmed the presence of sensorineural hearing loss (SNHL) in all patients. Twelve patients out of 27 had Class II hearing with the threshold between 31 and 50 decibels and a Speech Discrimination Score (SDS) of 50% to 69%. Ten patients had non-serviceable hearing and the remaining five had poor hearing. The audiogram was repeated after surgery for those 12 patients who had Class II hearing and showed that seven out of 12 patients maintained a hearing threshold within the range of Class II at the one-year follow-up (hearing preservation 58%). The facial nerve preservation rate was 56% considering House-Brackmann Grade III or less as acceptable facial nerve function. Conclusion The optimal treatment for small vestibular schwannomas is a matter of controversy; however, the choice of treatment for large vestibular schwannomas in patients without significant comorbidity is generally microsurgical excision. The surgical excision of a large VS with the retrosigmoid approach is found to be safe consistently. The hearing and facial nerve preservation in our study were found comparable with the literature.

Congenital and infantile malignant melanoma of the scalp: A systematic review.

Congenital and infantile malignant melanomas are rare and typically carry poor prognosis. The purpose of this article was to review the data on congenital and infantile malignant melanomas of the scalp in order to understand its presentation, diagnosis, management, and outcomes of congenital melanoma of scalp. We searched PubMed, CINAHL and Cochrane databases. Ten cases of congenital and 3 cases of infantile malignant melanoma of scalp were identified. The diagnosis was confirmed by biopsy and histological analysis for confirmation. The prognosis depends on the origin of disease (congenital melanocytic nevus, transplacental metastasis, or de-novo), tumor thickness, the presence of ulceration and/or necrosis, and anatomic site (scalp lesions having poor prognosis). The most commonly used treatment of the reported cases of congenital and infantile melanoma was surgical excision of the primary lesion. Further modes of treatment may be extrapolated from the treatment of childhood and adult melanomas.

Quality of Life in Individuals Surgically Treated for Congenital Hydrocephalus During Infancy: A Single-Institution Experience.

BACKGROUND: Congenital hydrocephalus (CH) is a frequently encountered birth anomaly that can hinder long-term neurologic maturity and social well-being of affected children. This study was undertaken to assess quality of life (QOL) 10-15 years after surgical treatment for primary CH during infancy at a tertiary care hospital in a developing country. METHODS: This retrospective cohort study included individuals who presented to Aga Khan University Hospital, Karachi, Pakistan, between 1995 and 2005 at <1 year old and underwent surgery for primary CH. The Hydrocephalus Outcome Questionnaire was used to assess outcomes with respect to QOL. RESULTS: Of 118 patients, 90 patients participated in the study. Mean age at first admission was 6.2 months. Mean length of follow-up was 5.4 years. Of these, 28 patients had died after surgery. Shunt infection (P = 0.012) and delayed milestones (P = 0.003) were found to be statistically significant factors affecting mortality in the patients who died. The mean overall health score was 0.67 ± 0.30. Age <6 months at the time of first surgery was a poor predictor of overall health on the Hydrocephalus Outcome Questionnaire (P = 0.039). CONCLUSIONS: In our analysis, we assessed the QOL associated with CH. We hope that these results will provide insight for future prospective work with the ultimate goal of improving long-term QOL in children with CH.

Cranioplasty after Craniectomy in a Pediatric Population: Single-Center Experience from a Developing Country.

Cranioplasty is a frequently performed procedure in neurosurgery. The pediatric population for this procedure is distinct from the adult one because of the growing skulls and thinner bones of the calvarium. A paucity of data on the outcomes of this procedure in the pediatric population has been identified repeatedly. We conducted a retrospective cohort study to investigate the outcomes in a pediatric population that underwent cranioplasty after craniectomy at our institute in a developing-world country. Our cohort showed no association of complication rate or cosmetic outcomes with the timing of cranioplasty, area of skull defect, type of implant used, or method of storage.
