ABSTRACT
INTRODUCTION: Meningiomas located in the posterior fossa and involving the sinodural angle at the junction of the transverse and sigmoid sinuses are uncommon and present unique challenges due to their complex anatomical location. Despite their distinctive features, they are frequently categorized with tentorial meningiomas in the literature. MATERIALS AND METHODS: This retrospective study conducted at a tertiary care center involved 64 patients with sinodural meningiomas who underwent surgical treatment between 2010 and 2023. The analysis covered demographics, clinical presentation, radiological characteristics, surgical approaches, histopathological findings, and outcomes. RESULTS: The cohort predominantly comprised females (83 %) with a mean age of 47.64 years. Headache (92.2 %) and gait disturbances (62.5 %) were the most common presenting symptoms. Preoperative imaging showed sinus involvement in 57.8 % of cases, predominating Sindou's type 1 and type 6. Gross total resection (Simpson grades 1-2) was achieved in 40.6 % of cases. Postoperative complications included pseudomeningocele (9.4 %), especially in patients with hydrocephalus. CONCLUSION: Sinodural meningiomas represent a distinct subset of posterior fossa tumors, necessitating meticulous preoperative planning and intraoperative decision-making regarding sinus management. The study underscores the importance of individualized surgical strategies and highlights the role of radiosurgery in managing residual disease effectively.
ABSTRACT
Trigonal meningiomas are rare intraventricular tumours that present a surgical challenge. There is no consensus on the optimal surgical approach to these lesions, though the transtemporal and transparietal approaches are most frequently employed. We aimed to examine the approach-related morbidity and surgical nuances in treating trigonal meningiomas. This retrospective review assimilated data from 64 trigonal meningiomas operated over 15 years. Details of clinicoradiological presentation, surgical approach and intraoperative impression, pathology and incidence of various postoperative deficits were recorded. In our study, Trigonal meningiomas most frequently presented with headache and visual deterioration. The median volume of tumours was 63.6cc. Thirty-one meningiomas each (48.4%) were WHO Grade 1 and WHO Grade 2, while 2 were WHO Grade 3. The most frequent approach employed was transtemporal (38 patients, 59.4%), followed by transparietal (22 patients, 34.4%). After surgery features of raised ICP and altered mental status resolved in all patients, while contralateral limb weakness resolved in 80%, aphasia in 60%, seizures in 70%, and vision loss in 46.2%. Eighteen patients (28.13%) developed transient postoperative neurological deficits, with one patient (1.5%) developing permanent morbidity. Surgery for IVMs results in rapid improvement of neurological status, though visual outcomes are poorer in patients with low vision prior to surgery, longer duration of complaints and optic atrophy. The new postoperative deficits in some patients tend to improve on follow up. Transtemporal and transparietal approaches may be employed, based on multiple factors like tumour extension, loculation of temporal horn, size of lesion with no significant difference in their safety profile.

INTRODUCTION: The role of decompressive craniectomy (DC) is as a rescue therapy for the treatment of intracranial hypertension. The indications for the DC are variable. METHODS: The clinical details, imaging, operative findings and follow-up data of children less than or equal to 18 years of age were reviewed for more information on the children who underwent DC in the last 5 years. RESULTS: During the study period, a total of 128 children underwent DC. The trauma cases were 66, and the non-trauma cases were 62. The common indication for DC was pure acute subdural hematoma 33 (50%), followed by contusion 10 (15%) in the trauma group, and in non-trauma, arterial infarction in 20 (32%) and cerebral venous thrombosis in 17 (27%). Hemicraniectomy was done in 114 (89%), and bifrontal craniectomy was done in 7 (5.4%) cases. The median duration follow-up was 7 months in non-trauma and 6 months in trauma. GCS was less than 8, the motor score was less than 3, and pupillary asymmetry, hypotension and basal cistern effacement were factors related to an unfavourable outcome in the non-trauma group. In regression analysis, only a motor score of less than three was associated with the non-trauma group. Age less than 10 years, GCS less than 8, motor score less than three and preoperative infarction were the predictive factors in univariate analysis, and only GCS less than 8 was the predictive factor for unfavourable factors in regression analysis in the trauma group. CONCLUSION: The DC is performed as a lifesaving procedure. The unfavourable outcome is slightly higher in non-trauma cases compared to trauma cases. However, the mortality rate is high in trauma cases.
ABSTRACT
OBJECTIVE: Rosai-Dorfman disease (RDD) is a rare benign proliferative disorder of histiocytes. The study discusses the intracranial RDD approach, its management, and its outcome. METHODS: It is a retrospective study performed in a tertiary center, the National Institute of Mental Health and Neuroscience, Bangalore, from January 2010 to December 2022. The biopsy-proven patients of RDD were recruited in the present cohort. Demographic and surgical details were collected from the record section, and radiology was collected from the internal storage system. Follow-up assessments were done clinically and telephonically. RESULTS: A total of 25 patients matched the criteria. The mean age was 32 ± 13.4 years, with male predominance. We have included only cranial cases (N=25). Among the intracranial lesions, 5/25 (20 %) patients had multicentric lesions. All the lesions were avidly enhancing on contrast, and 16 (64 %) lesions were hypointense on T2. Perilesional edema (T2/Flair hyperintensities in the surrounding white matter) was seen in 12 (48 %) patients. Gross total resection (GTR) was carried out in six (24 %) cases. Sub-total resection was in 14 (56 %), and biopsy was in five cases (20 %). Nineteen patients received adjuvant therapy, either only steroid (40 %), only low-dose radiotherapy (16 %), only Chemotherapy (4 %), or a combination of both. At follow-up,44 % of patients had stable disease,28 % had primary disease or recurrence growth, and regression in 12 % of cases. CONCLUSION: We demonstrate that surgical resection is an effective therapy for treating isolated intracranial RDD. Adjuvant therapy is an add-on treatment for skull base locations in multicentric locations or surgically inaccessible locations.

INTRODUCTION: Diffuse midline glioma (DMG) is a relatively new entity which was introduced in the fourth edition of the WHO classification of CNS tumours in 2016 and later underwent revision in 2021. It is an infiltrative glioma arising from midline structures, viz., thalamus, spine, and brainstem. Current literature on DMG is based majorly on brainstem lesions, and DMGs arising elsewhere remain unexplored. In our study, we have discussed our experience with thalamic DMGs. METHODOLOGY: This is a retrospective observational study of all patients with histopathologically proven DMG H3K27M altered, arising in the thalamus from 2018 to 2022. Clinical, neuroimaging, and pathology were re-reviewed, and prognostic factors for 3 months, 6 months, and overall survival (OS) were analyzed for all patients. RESULTS: There were 89 patients- 64 adults and 25 pediatric patients with thalamic DMG. The median age at presentation was 24 years. Raised ICP followed by limb weakness were the most common presenting complaints. Stereotactic biopsy was performed in 64 (71.9â¯%) patients and surgical decompression in 25 (28.1â¯%) patients. CSF diversion was required in 53 (59.6â¯%) patients. Median survival was 8 months in adults and 7 months in pediatric (p-value: 0.51). Raised ICP and TP53 mutation were prognostic factors in pediatric population. Radiotherapy with or without chemotherapy improved survival (p-value- <0.01). CONCLUSION: Thalamic DMGs have a poor prognosis which is comparable to brainstem DMGs. Radiotherapy improves survival in these patients. However, the disease remains an enigma and further work delving into its molecular characterization should be encouraged.

PURPOSE: This study aims to discuss the management challenges of huge hydrocephalus (HH), a severe subset of hydrocephalus, presenting predominantly in underprivileged backgrounds. Insights into the condition's characteristics, factors affecting outcomes, and associated morbidity are discussed. METHODS: A retrospective review of all operated cases of hydrocephalus with head circumference greater than body length (HC>L) was conducted (January 2019-January 2023). Data on epidemiological parameters, associated cranial abnormalities, cortical mantle thickness, peri-conceptional folic acid intake, surgical interventions, age-appropriate milestones, and complications were collected. Follow-up was conducted for at least 12 months or until expiration. RESULTS: The cohort consisted of 7 males and 5 females with age ranging from 3 to 48 months. 33% of them had associated neurological abnormalities, and 18 surgical interventions were needed for these 12 cases, including ventriculoperitoneal shunt or endoscopic diversion. A 17% wound breakdown rate requiring re-suturing was present, and 33% of cases had postoperative CSF infection, with 33% mortality, with only one case having age-appropriate development seen. The average hospital stay was 11.9 days, six times our center's average. All cases with an Evans index with an average of 0.7 expired within 12 months. None of the 12 mothers took peri-conceptional folic acid, and no case agreed to reduction cranioplasty. CONCLUSION: Huge hydrocephalus is a rare cohort with significant management challenges and poor prognosis even after treatment. Factors such as delayed intervention and low socioeconomic status contribute to adverse outcomes. Prevention through peri-conceptual folic acid intake and addressing socioeconomic disparities is crucial in reducing disease burden and improving prognosis.

BACKGROUND: Diffuse intrinsic pontine gliomas are aggressive tumors that carry a poor prognosis with a 2-year survival rate of <10%. The imaging appearance is often pathognomonic, and surgical biopsy is not mandatory to initiate treatment in children. Studies of biopsy samples provide insight into the disease's molecular pathobiology and open prospects for targeted therapy. This study was conducted to determine the diagnostic yield and safety of stereotactic biopsies. METHODS: This is a prospective observational study from a single tertiary health care center. All patients with clinical and radiological features diagnostic of diffuse intrinsic pontine gliomas (DIPGs) who underwent biopsy from July 2018 to June 2023 were included. Biopsies were performed using either stereotactic frame-based, frameless, or endoscopic techniques. RESULTS: A total of 165 patients with DIPGs were evaluated in the study period. The option of biopsy with its associated risks and benefits was offered to all patients. A total of 76 biopsies were performed in 74 patients (40 children and 34 adults, including 2 repeat biopsies). The median age was 15 years. Diffuse midline gliomas, H3K27M altered, was the most common histopathological diagnosis (85% pediatric and 55.9% adults). The diagnostic efficacy of the procedure was 94.7%. The complication rate was 10.8%, with no permanent neurological deficits due to surgery. There was no procedure-related mortality. CONCLUSIONS: Establishing the safety of the procedure could be an important step toward popularizing the concept, which might offer a better understanding of the disease. Brainstem eloquence and a lack of direct benefit to patients are the primary obstacles to brainstem biopsy.

Background and Objective Surgery is the treatment of choice for growth hormone (GH)-secreting pituitary adenoma. The remission of random GH depends on various factors. We aimed to evaluate the predictors related to remission of random GH following surgical treatment. Methods We collected the data retrospectively from the chart review from a single unit of neurosurgery. The diagnostic criteria for remission were a random GH < 1 ng/mL or nadir GH < 0.4 ng/mL after an oral glucose tolerance test. Results Data from a total of 110 (females 62 [56.4%]) patients were available for follow-up and were analyzed. The mean age was 36.5 years (14-69 years). Vision impairments were seen in 39 (35.5%) patients. The mean duration of symptoms before surgery was 34 months. The mean volume of the tumor was 7.2 mL (0.44-109.8 mL). Knosp grade 3 and 4 tumors were seen in 41.5% of cases. The mean preoperative random GH level was 68.9 ng/mL. Transsphenoidal surgery was done in 107 (97.3%) cases. The gross total resection could be done in 36 (32.7%) cases. At 3 months, 25 (26%) patients had a biochemical remission. In univariable analysis, lower Knosp grade, preoperative GH level < 40 ng/mL, gross total resection, and male gender were associated with remission at 3 months. In regression analysis, preoperative GH and male gender were related to remission at 3 months. Conclusion The preoperative GH level < 40 ng/mL is associated with higher chances of remission after surgery for GH-secreting pituitary adenoma.
ABSTRACT
Suprasellar cysticercosis is a rare entity. Only a few cases are reported in the literature.1 Clinically, present with visual loss and endocrinopathy and radiologically mimic craniopharyngioma, cystic pituitary adenoma, and Rathke cleft cyst.2 We present the case of a 34-year-old woman with a history of diminution of vision for 2 months. On examination, her visual acuity was 6/9 bilaterally, per the Snellen chart. The visual field showed incomplete temporal hemianopia in the right eye and a severely depressed field in the left eye. She was evaluated with magnetic resonance imaging (MRI) of the brain, which showed multiple well-defined enhancing cystic lesions in the suprasellar cistern splaying the optic chiasm. Enzyme-linked immunoelectrotransfer blot testing was not done due to the lack of availability at our center. She underwent left pterional craniotomy and excision of the cysts. Multiple cysts were noted during surgery, and all were dissected from the surrounding structures. However, there was a spillage of cystic contents during excision, and they are not associated with any adverse reactions, unlike hydatid cysts.3 She recovered well. Histopathology suggestive of cysticercal cyst, no scolexes. As per Infectious Diseases Society of America, non-operated subarachnoid neurocysticercosis requires prolonged antiparasitic agents along with steroids.4 She received 6 weeks of albendazole 15 mg/kg/day and steroids tapered over 3 weeks. At 2 years of follow-up, her visual acuity improved to 6/6 with a normal visual field. Follow-up MRI showed complete removal of all cysts with no relapse. Early surgery is safe and effective. Visual outcome depends on the timing of the diagnosis and prompt intervention.

Mirror movements, characterized by involuntary symmetrical movements in contralateral body parts during intentional movements, have been associated with various neurological conditions. Limited dorsal myeloschisis (LDM), a rare form of spinal dysraphism, is defined by a focal closed midline defect and a fibro-neural stalk connecting the skin lesion to the underlying cord. We present a unique case of a 4-year-old girl with cervical LDM exhibiting mirror movements. The patient underwent surgical exploration, skin tag excision, fibrous tract removal, and cervical spinal cord detethering. Post-operatively, there was a partial improvement in mirror movements and a complete resolution of hand grip weakness.

Purpose: The study aims to evaluate the role of substance P in cerebral edema and outcomes associated with acute TBI. Method: Patients with acute TBI who presented within 6 h and a CT scan showed predominantly cerebral edema were included in the study. Substance P level was assessed from a serum sample collected within 6 h of trauma. We also evaluated the brain-specific gravity using the Brain View software. Result: A total of 160 (128 male) patients were recruited. The median serum substance P concentration was 167.89 (IQR: 101.09-238.2). Substance P concentration was high in the early hours after trauma (p = 0.001). The median specific gravity of the entire brain was 1.04. Patients with a low Glasgow coma scale (GCS) at admission had a high concentration of the substance P. In the univariate analysis, low GCS, elevated serum concentrations of substance P level, high Rotterdam grade, high cerebral edema grade, a high international normalized ratio value, and high blood sugar levels were associated with poor outcomes at six months. In logistic regression analysis, low GCS at admission, high cerebral edema grade, and elevated blood sugar level were strongly associated with poor outcomes at six months. The area under the receiver operating characteristic curve was 0.884 (0.826-0.941). Conclusion: Serum substance P is strongly associated with the severity of cerebral edema after TBI. However, brain-specific gravity does not directly correlate with posttraumatic cerebral edema severity. Serum substance P does not influence the clinical outcome of traumatic brain injury.
ABSTRACT
INTRODUCTION: Meningiomas are the most common primary intracranial tumour. Gamma knife radiosurgery (GKRS) is a frequently employed non-invasive method of treatment, with good remission rates and low morbidity in literature. However, the role of GKRS in the management of "large" meningiomas is unclear, with reported outcomes that vary by centre. We aimed to assess the factors that influence long-term outcomes following GKRS in meningiomas >10 cc in volume. METHODS: A retrospectively analysed all patients with meningiomas exceeding 10 cc in volume who underwent GKRS between January 2006 and December 2021 at the National Institute of Mental Health and Neurosciences (NIMHANS), Bengaluru. Demographic, clinical, radiological, and follow-up data were acquired, and factors associated with progression following GKRS were assessed. RESULTS: The cohort comprised 76 patients 29 males (38.2%) and 47 females (61.8%) with a mean age of 46.3 ± 11.02 years. Thirty-nine patients had been previously operated (51.3%). Meningiomas were most frequently located in the parasagittal region (26 tumours, 34.2%) and sphenopetroclival region (23 tumours, 30.3%), with mean lesion volume of 12.55 ± 5.22 cc, ranging 10.3 cc-25 cc. The mean dose administered to the tumour margin was 12.5 Gy ± 1.2 Gy (range 6-15 Gy). The median duration of clinical follow-up was 48 months, over which period radiological progression occurred in 14 cases (20%), with unchanged tumour volume in 20 cases (28.6%) and reduction in size of the tumour in 36 cases (51.4%). Progression-free survival after GKRS was 72% at 5 years, was significantly poorer among meningiomas with tumour volume >14 cc (log-rank test p = 0.045), tumours presenting with limb motor deficits (log-rank test p = 0.012), and tumours that underwent prior Simpson grade 3 or 4 excision (log-rank test p = 0.032). CONCLUSIONS: Meningiomas >10 cc in volume appear to display a high rate of progression and subsequent need for surgery following GKRS. Primary surgical resection, when not contraindicated, may be considered with GKRS serving an adjuvant role, especially in tumours exceeding 14 cc in volume, and presenting with limb motor deficits. Long-term clinical and radiological follow-up is essential following GKRS as the response of large meningiomas may be unpredictable.

INTRODUCTION: Resection of meningiomas (THMs) at the torcular Herophili poses challenges to surgeons due to complex regional anatomy. The current study aims to evaluate factors affecting the extent of resections, progression-free survival, and the role of radiation. METHODS: We did a retrospective study of all the THM patients treated at our institute between May 1987 and June 2022. The demographic data, signs and symptoms, surgical notes, postoperative details, and radiotherapy were gathered retrospectively. Survival analysis was done with Kaplan-Meier tests along with predictors of the extent of resection as well as recurrence. RESULTS: A total of 39 patients qualified to be included in the study, with 10 male patients (male:female 1:2.9) and an average age of 50.8 years. The average follow-up duration was 75.9 months. Simpson's grade 2 excision was achieved in 19 (48.7%) patients, followed by Simpson's grade 3 excision in 17 patients (43.6%). Progression-free survival in subtotal resection was 60 months, and 100 months in gross total resection. Statistically, the extent of the resection was determined by the involvement of sinuses/torcula and the number of quadrants involved around torcula. A total of 16 patients received radiosurgery for the residual or small reccurrence of the lesion. Follow-up revealed reccurrence in 5 cases. CONCLUSIONS: Torcular meningiomas are relatively uncommon, described in few reports, and represent a therapeutic dilemma. Though some experts recommend complete removal of tumor and reconstruction of the sinus, others suggest maximum safe resection, followed by radiosurgery. The present study reflects reasonable control of the residual lesion with radiosurgery after maximum safe resection.

PURPOSE: The purpose of this study was to compare outcomes of endoscopic third ventriculostomy (ETV) and ventriculoperitoneal shunt (VPS) in children with symptomatic triventricular hydrocephalus due to primary aqueductal stenosis. METHOD: This is a retrospective analytical study. Patients who underwent either ETV or VPS as the first procedure for hydrocephalus due to primary aqueductal stenosis were included in the study. RESULT: A total of 89 children were included in the study for analysis. The mean age was 8.4 years. Forty-four (49.4%) had their first surgery as ETV and 45 (50.6%) had their first surgery as VPS. Overall, 34 (38.2%) patients required a second surgery (either ETV or VPS) for persistent or recurrent hydrocephalus. The mean follow-up duration was 832.9 days. The overall complication rate was 13.5%. The mean timing of the second surgery after index surgery was 601.35 days. Factors associated with a second surgery were the presence of complications, high protein in cerebrospinal fluid, the relative change of frontal-occipital horn ratio (FOHR) and Evans' index. The survival of the first surgery was superior in ETV (751.55 days) compared to VPS (454.49 days), p = 0.013. The relative change of fronto-occipital horn index ratio (FOIR) was high in the VPS (mean 7.28%) group compared to the ETV (mean 4.40%), p = 0.001 group. CONCLUSION: Overall procedural survival was better after ETV than VPS for hydrocephalus due to aqueductal stenosis. VPS causes more reduction in linear indices of ventricles as compared to ETV, however, is not associated with the success or complication of the procedure.

OBJECTIVE: Shunt malfunction is a complication that can have devastating implications. In this study, the authors aimed to evaluate the rate of shunt revision in a single institution over 5 years and to determine the factors associated with shunt revision in the pediatric population. METHODS: This retrospective report assimilated data from all patients ≤ 18 years old who underwent shunt surgery between January 2015 and April 2021 at the authors' institute with a minimum of 3 months of follow-up. Patient data regarding demographic characteristics, indications, clinical status, point of entry, operative and CSF findings, revision interval, and cause of failure were collected. RESULTS: Between January 2015 and April 2021, 1112 pediatric patients underwent initial shunt surgery at the authors' institute, among whom 934 patients met the inclusion criteria. Ninety-five patients underwent revision (shunt revision rate 10.2%). The cohort comprised 562 male and 368 female patients (no sex was recorded in 4 cases), with infratentorial tumors (37.8%) being the most common indication for the shunt. Multivariate analyses revealed that younger patient age, right-sided shunt, single surgeon, and shunt placement done in the evening and night were significantly associated with shunt failure. Among all the factors analyzed, female sex had the greatest risk of early shunt failure (OR 2.90 [95% CI 1.09-8.16], p = 0.037). The presence of prior external ventricular drainage was associated with an increased risk of multiple revisions (OR 6.67 [95% CI 1.60-32.52], p = 0.012). The most common cause of failure was obstruction, usually at the cranial end. The most common cause of distal failure was malposition of the abdominal end. CONCLUSIONS: This study identifies various factors associated with shunt failure. Various goal-directed strategies toward modifiable risk factors can significantly improve shunt survival.

Objectives: Pain is common after craniotomy. Its incidence and predictors in developing nations are not adequately studied. We aimed to assess the incidence, predictors, and impact of acute post-operative pain after intracranial neurosurgeries. Materials and Methods: This prospective observational study was conducted in adult patients undergoing intracranial neurosurgeries. After patient consent, ethics committee approval, and study registration, we assessed the incidence of post-operative pain using numerical rating scale (NRS) score. Predictors and impact of pain on patient outcomes were also evaluated. Results: A total of 497 patients were recruited during 10-month study period. Significant (4-10 NRS score) post-operative pain at any time-point during the first 3 days after intracranial neurosurgery was reported by 65.5% (307/469) of patients. Incidence of significant pain during the 1st post-operative h, on the 1st, 2nd, and 3rd post-operative days was 20% (78/391), 50% (209/418), 38% (152/401), and 24% (86/360), respectively. Higher pre-operative NRS score and pain during the 1st h post-operatively, predicted the occurrence of pain during the first 3 days after surgery, P = 0.003 and P < 0.001, respectively. Pain was significantly associated with poor sleep quality on the first 2 post-operative nights (P < 0.001). Patient satisfaction score was higher in patients with post-operative pain, P = 0.002. Conclusion: Every two in three patients undergoing elective intracranial neurosurgery report significant pain at some point during the first 3 postoperative days. Pre-operative pain and pain during 1st post-operative h predict the occurrence of significant post-operative pain.
ABSTRACT
Background and Study Aims The treatment of craniopharyngioma is varied. The treatment ranges from radical excision to direct radiotherapy. As the morbidity of excision is high, more conservative approaches are used. Transventricular endoscopy is a minimally invasive treatment for cystic craniopharyngiomas. The objective of this study is to describe a personal experience with this method of treatment. Material and Methods This is a retrospective review of a series of patients managed with endoscopic catheter and reservoir placement for cystic craniopharyngiomas. Results Twenty-nine patients presented with clinical features of raised intracranial features. Imaging showed a predominantly cystic craniopharyngioma extending into the third ventricle with hydrocephalus. All patients underwent transcortical transventricular endoscopic biopsy, and catheter placement connected to a reservoir. There was no morbidity ascribed to the endoscopic procedure when fenestration and aspiration or fenestration and reservoir were placed. Twelve patients underwent radiotherapy. The median duration of follow-up was 18 months (3-72 months). Eight (27.5%) cases had recurrences. Five (17.2%) could be managed with only reaspiration, two (6.8%) required craniotomy and resection, and one (3.4%) could be managed only with ventriculoperitoneal shunt. Conclusion The neuroendoscopic fenestration, aspiration of cyst, and placement of catheter reservoir followed by radiation is an optional treatment for predominantly cystic craniopharyngiomas arising within or extending into the third ventricle causing hydrocephalus.
ABSTRACT
Objectives: Patient satisfaction is an indicator of the quality of healthcare. It can improve treatment adherence and health outcomes. This study aimed to determine the incidence, predictive factors, and impact of post-operative patient dissatisfaction with perioperative care after cranial neurosurgery. Materials and Methods: This was a prospective observational study conducted in a tertiary care academic university hospital. Adult patients undergoing cranial neurosurgery were assessed for satisfaction 24 h after surgery using a five-point scale. The data regarding patient characteristics that may predict dissatisfaction after surgery were collected along with ambulation time and hospital stay. Shapiro-Wilk test was used to assess normality of data. Univariate analysis was performed using Mann-Whitney U-test and significant factors were entered into binary logistic regression model for identifying predictors. The level of significance was set at P < 0.05. Results: Four hundred and ninety-six adult patients undergoing cranial neurosurgery were recruited into the study from September 2021 to June 2022. Data of 390 were analyzed. The incidence of patient dissatisfaction was 20.5%. On univariate analysis, literacy, economic status, pre-operative pain, and anxiety were associated with post-operative patient dissatisfaction. On logistic regression analysis, illiteracy, higher economic status, and no pre-operative anxiety were predictors of dissatisfaction. The patient dissatisfaction did not impact ambulation time or duration of hospital stay after the surgery. Conclusion: One in five patients reported dissatisfaction after cranial neurosurgery. Illiteracy, higher economic status, and no pre-operative anxiety were predictors of patient dissatisfaction. Dissatisfaction was not associated with delayed ambulation or hospital discharge.
ABSTRACT
Spinal ependymoma with MYCN amplification is a newly recognized type of spinal ependymoma that is known to be associated with poor prognosis. Available studies on this relatively rare tumor type have observed that these tumors tend to disseminate along the spinal cord and behave aggressively with worse overall and progression-free survival compared to the other types of ependymoma. In this study, we describe the clinical and histopathological features of spinal ependymomas in a single institution cohort with emphasis on those with MYCN amplification.

INTRODUCTION: Post-operative delirium (POD) is a major complication after anesthesia and surgery with an incidence varying from 5 to 50%. The incidence of POD after intracranial surgery is likely to be higher due to the pre-existing brain pathology and direct handling of the brain during neurosurgery. The primary objective of this study was to assess the incidence of POD after intracranial neurosurgery and our secondary objective was to identify the potential risk factors for its occurrence. MATERIALS AND METHODS: This prospective observational study was conducted after the institutional ethics committee approval between october 2020 and march 2021. We included patients of either gender aged ≥ 18 years and undergoing elective intracranial neurosurgery. Exclusion criteria included patients aged below 18 years, undergoing emergency neurosurgery, patients with impaired consciousness and patients with psychiatric comorbidities or those taking psychotropic medications. We planned to exclude patients from analysis who were transferred to intensive care unit (ICU) or if they were not extubated after surgery. Our study outcome was development of POD as assessed by confusion assessment method (CAM). RESULTS: The overall incidence of POD during the three postoperative days was 19.2% (n=60/313). The incidence of POD on days 1, 2, and 3 were 19.2% (n=60/313), 17.2% (n=50/291), and 16.3% (n=39/239). Preoperative delirium and hyperactive Emergence Delirium were found to be the significant predictors of POD. CONCLUSION: Every one in five patients undergoing intracranial neurosurgery is vulnerable for the development of POD within first three days after surgery. The incidence of occurrence of POD is time-sensitive and is decremental.
