Neurosurgery as a Top-Drawer Choice for Residency in India: Reality or Myth?

INTRODUCTION: This survey was conducted to explore the perceptions of undergraduate (UG) medical students regarding enrolling in a neurosurgical training program. The purpose was to understand' expectations, reasons, apprehensions, and variables influencing students' decisions to pursue a career in neurosurgery. The results shed light on students' perceptions and can help educational institutions and training programs draw in and encourage aspiring neurosurgeons. METHODS: A 35-point online questionnaire was created using Google Forms (Google LLC) after content and face validation and circulated using social media platforms among various public medical colleges across India. Responses were collected over a period of 3 months, from February 2023 to April 2023. A 5-point Likert scale was used to collect the responses wherever applicable. RESULTS: A total of 1042 respondents from 47 medical colleges completed the survey. The majority of the students were not exposed to neurosurgery during their UG program, but despite this, 60.1% (n = 627) were willing to consider it as their career option. Around 91.4% of the respondents perceived neurosurgery to be a challenging but prestigious specialty that has a long learning curve and the worst work-life balance when compared with other specialties. The majority of the respondents (strongly disagree = 24.3%, n = 253; disagree = 31.7%, n = 330) did not view neurosurgery as a male-dominated specialty. Most students preferred a 6-year training program over a 3-year program (P = 0.001) if their medical college had such a course. CONCLUSIONS: Our study reveals that although a majority of the UG students would like to join neurosurgery residency, there are significant barriers in the form of less exposure, negative perceptions, and apprehensions toward the branch. Enhancing medical students' awareness about neurosurgery necessitates the integration of hands-on workshops, simulation-based training, didactic lectures, and neurosurgery rotations into the UG curriculum.

Pediatric primary intracranial angiosarcoma with epithelioid differentiation: a surgeon's dilemma.

Angiosarcoma is a rare form of soft tissue sarcoma originating from endothelial tissue, accounting for < 1% of all sarcomas. Primary epithelioid angiosarcomas of the central nervous system (CNS) are even more elusive, with only four reports described in the literature. In this article, we describe the first case in pediatric population, with a brief literature review regarding this entity. A 13-year-old girl presented to emergency services with raised intracranial pressure. MRI demonstrated a heterogenous lesion in the temporal lobe. She underwent emergency craniotomy and subtotal excision of the tumor. Eventually the patient developed multiple infarcts and succumbed post operatively. Pre-operative diagnosis on radiology is difficult considering the rarity of this entity and heterogeneity in radiological appearance. One needs to have a high degree of suspicion to consider angiosarcoma as a radiological differential. Overall prognosis remains poor. Early adjuvant treatment may improve overall survival.

Role of Cavernous Sinus Extension and MRI T2 Hypointensity in the Extent of Resection following Trans-Sphenoidal Surgery for Giant Pituitary Adenomas.

Background: Giant pituitary adenomas (GPA) pose a significant neurosurgical challenge. In this study, we present an experience of 60 consecutive patients with GPA operated by trans-sphenoidal surgery (microscopic/endoscopic). Objective: The aim of this study was to elucidate preoperative factors predicting extent of resection (EOR) following transsphenoidal surgery for GPA. Materials and Methods: The study was a retrospective evaluation of 60 adult patients (>18 years) with GPA operated over a decade. The patients were analyzed for their clinical presentation, EOR, radiology, visual outcome, endocrinological outcome, and complications. Results: The mean age of the cohort was 41.5 ± 13.3 years, mean tumor volume was 38.2 ± 19.1 cm3, and mean follow-up was 30.6 ± 21.7 months. Improvement in vision was seen in forty patients (66.7%), while another 16 (26.7%) had stable vision as prior to surgery. Duration of visual symptoms was found to be statistically significantly associated with postoperative improvement of vision (P = 0.001). Twenty-four patients (40.0%) underwent subtotal resection (STR), while the remaining 36 patients (60.0%) underwent either gross total or near-total resection. Factors associated with STR were retrosellar (P = 0.04), subfrontal (P = 0.02), Knosp 3,4 cavernous sinus extension (P = 0.03), and MRI T2 hypointensity (P = 0.02). During follow-up, eight patients (13.3%) had radiological evidence of growth of residual tumor. Conclusions: Most cases of GPA can be adequately handled by trans-sphenoidal surgery. The presence of retrosellar, subfrontal, cavernous sinus extensions, and T2 hypointensity should alert the surgeon for likelihood of STR, postoperative residual tumor hemorrhage and need for second-stage endonasal or transcranial surgery. However, utilization of extended endoscopic route has allowed good debulking of tumors having subfrontal and parasellar extensions, which was not possible previously using traditional microscopic transsphenoidal surgery.

Primary Dural Acute Lymphoblastic Leukaemia/Lymphoma Masquerading Meningioma: Report of a Case and Review of Literature.

Acute lymphoblastic leukaemia/lymphoma (ALL) is a systemic disease which primarily involves bone marrow or lymphoid organs. Extranodal presentation of ALL is uncommon, and ALL presenting as a dural mass is exceedingly rare. Here we present a case of primary dural B-cell ALL which was preoperatively diagnosed as meningioma on clinico-radiological grounds. A 27-year-old female patient presented with left hemicranial headache for one month's duration along with progressive vision loss of in both eye and altered behaviour. Contrast enhanced magnetic resonance imaging (CE-MRI) suggest dural based mass with dural tail sign. Histopathological examination of the resected specimen revealed B-cell ALL. Further systemic investigations didn't suggest any peripheral blood, bone marrow or lymph node involvement. To the best of our knowledge, only two cases of primary dural ALL have been reported in the literature so far. This report highlights the diagnostic difficulty in extramedullary precursor lymphoid neoplasm.

Factors determining the requirement of surgical intervention and prognosis in cases of traumatic bifrontal contusions: A prospective observational study.

Background: Traumatic brain injury, being a notorious cause of mortality and morbidity across the globe, presents with a variety of lesions. One of the distinct patterns of injury is characterized by contusions of both frontal lobes, labeled "traumatic bifrontal contusions" (TBCs). TBC is often associated with the presence of significant edema and mass effect leading to rapid clinical deterioration after a usually benign presentation at the time of first evaluation. Formulating a management plan in a patient with TBC is often more difficult than in a patient with a major intracranial hematoma. Methods: A prospective observational study with aims and objectives to identify predictors of an unfavorable outcome, analysis of the evolution of TBC, evaluation of the specific indications for surgery, and determination of the prognosis. All head trauma patients harboring bifrontal contusions were included in the study. Patients with other associated operable injuries involving blunt trauma abdomen and orthopedic injuries, counter-coupe injuries, and obvious open fractures noted over calvaria were excluded from the study. Glasgow coma scale (GCS) was recorded during the first assessment, followed by non-contrast computerized tomography (NCCT) Head. Results: A total of 53 patients satisfying inclusion and exclusion criteria were included in the study. The average GCS score recorded before surgical intervention was 9. The mean and median best motor response noted was M5. The interval from the time of injury to the first NCCT of the brain at the study hospital ranged from 3 h to 163 h, averaging 17.66 h. The median category w.r.t Marshall's CT classification observed was "Diffuse Injury IV." The volume of the contusions in each scan was estimated, and the average anterior cranial fossa volume observed was 125 mL. "Upfront surgery" ("Bifrontal decompressive craniectomy" or "unilateral Fronto-Temporo-Parietal [FTP] decompressive hemicraniectomy") was carried out on the day of admission based on the findings on the first NCCT brain. About 49% of patients at presentation needed surgical intervention as per existing protocols. The duration of observation for patients who were initially observed but eventually had to undergo surgery ranged from 1 to 5 days, with an average observation period of 2 days. The duration of observation in those who did not subsequently need surgery ranged from 7 to 10 days, with an average duration of 9 days. Conclusion: What leads to the poorly predictable, delayed, and rapid deterioration that sets TBCs apart from other traumatic brain injuries is still unclear. Our study finds that having a low threshold for repeat CT imaging of the patient led to earlier identification of progression, and a low threshold for surgical intervention led to favorable outcomes.

Setting up a Neurosurgical Skills Laboratory and Designing Simulation Courses to Augment Resident Training Program.

Background: The surgical skill practice in neurosurgery is being compromised in the recent past owing to the duty time constraint, patient safety concerns, and medico-legal issues. Surgical practice outside the operating room is essential to enhance a resident's operative skills and to gain confidence. Objective: To discuss the experience of establishing an 'in-house neurosurgery skills laboratory' and various training sessions conducted with cadaveric and non-cadaveric simulation modules. Methods: A skills laboratory was set up in the existing resident teaching hall with nine workstations. Each station has been equipped with an operating table, surgeon's chair, basic microscope, endoscope, high-speed drill system, and a suction machine. Vascular anastomosis, high-speed drilling, and basic neuroendoscopy were planned on low-cost non-cadaveric modules. Craniotomy and various surgical approaches were designed on cadaveric modules obtained from the anatomy department. Result: A total of 18 residents in divided groups during their initial three semesters had participated in the non-cadaveric simulation courses. Twenty-six residents had participated and 12 sessions were conducted on the cadaveric modules. Three workshops were conducted and 20 residents and faculty members from five other institutions had participated in the cadaveric hands-on training session. Conclusion: A well-equipped skills laboratory provides an opportunity for the residents to acquire operative expertise in a similar atmosphere to that of the operating theater. A structured program comprising various operative practice sessions should be incorporated into the resident training program.

Primary Hypofractionated Gamma Knife Radiosurgery for Giant Cavernous Sinus Hemangiomas.

Cavernous sinus hemangioma (CSH) are notoriously difficult to excise because of their location, propensity for profuse bleeding during surgery, and relationship to complex neurovascular structures. Radiosurgery offers an alternative treatment modality in cases of small and medium-sized CSH. However, no reports are available in the world literature detailing gamma knife radiosurgery (GKRS) in large (3-4 cm) and giant (>4 cm) CSH. Two patients with giant CSH (Tumor volume was 72.2 and 99.8 cm3, respectively) were treated with frame-based fractionated GKRS (5 Gy × 5 #). The treatment was done with Leksell Perfexion with frame in situ and interfraction interval of 24 h. The tumor was engulfing the optic apparatus, and chiasma could not be separated delineated. The patients were followed at 3 months interval with clinic-radiologic evaluation. Following GKRS, both patients showed remarkable clinical improvement in presenting complaints of headache and visual deterioration. Sixth nerve paresis recovered completely in case no. 1. Significant reduction in tumor volumes (85.1 and 75.6% respectively) was noticed in both the patients at 6 months follow-up radiology. Transient alopecia was noted in case 1 at 3 months follow-up that completely resolved by the 6 months. There was no complication till the last follow-up of 9 months. We report the first account of five fraction frame-based hypo fractionated GKRS for giant CSH. At an interval as short as 3 months, giant CSH shows remarkable clinical improvement. Primary hypofractionated GKRS may be considered an alternative effective modality in these difficult lesions with a favorable safety profile.

Head injury care in a low- and middle-income country tertiary trauma center: epidemiology, systemic lacunae, and possible leads.

BACKGROUND: Although head injury (HI) from low- and middle-income countries (LMIC) heavily contributes to the global disease burden, studies are disproportionately less from this part of the world. Knowing the different epidemiological characteristics from high-income nations can target appropriate prevention strategies. This study aims to provide a comprehensive overview of the clinico-epidemiological data of HI patients, focusing on the existing challenges with possible solutions from a developing nation's perspective. METHODS: This is a prospective, registry-based, observational study of HI in an Indian tertiary trauma-care center over 4 years. Various clinico-epidemiological parameters, risk factors, and imaging spectrum were analyzed in a multivariate model to identify the challenges faced by LMIC and discuss pragmatic solutions. RESULTS: The study included a large-volume cohort of 14,888 patients. Notably, half of these patients belonged to mild HI, despite most were referred (90.3%) cases. Only one-third (30.8%) had severe HI. Less than a third reached us within 6 h of injury. Road traffic accidents (RTA) accounted for most injuries (61.1%), especially in the young (70.9%). Higher age, males, RTA, helmet non-usage, drunken driving, systemic injuries, and specific imaging features had an independent association with injury severity. CONCLUSIONS: The study represents the much-needed, large-volume, epidemiological profile of HI from an LMIC, highlighting the suboptimal utilization of peripheral healthcare systems. Strengthening and integrating these facilities with the tertiary centers in a hub and enhanced spoke model, task sharing design, and efficient back-referrals promise effective neurotrauma care while avoiding overburden in the tertiary centers. Better implementation of road safety laws also has the potential to reduce the burden of HI.

Vim stereotactic radiosurgical thalamotomy for drug-resistant idiopathic Holmes tremor: a case report.

We share our experience with stereotactic gamma knife thalamotomy (GKT) for medically refractory Holmes tremor (HT). A 22-year-old patient underwent gamma knife thalamotomy at ventrointermediate nucleus for disabling HT of the right upper limb. A single 4-mm isocenter was used to target the ventral intermediate nucleus with 130 Gy radiation. At 4 months follow up, we observed 84% improvement in his Fahn-Tolosa-Marin (FTM) rating scale with significant improvement in the right upper limb dystonic tremor. There was only subtle improvement in the ataxic component of the right lower limb. At 1 year after stereotactic GKT, there was sustained neurological improvement with no side effect, We present the stereotactic GKT as a treatment modality for drug-resistant HT. Moreover, it may be considered an alternate treatment modality especially in patients reluctant or contraindicated for any invasive surgical technique. CLINICAL TRIAL REGISTRATION NUMBER: Not required.

Neurosurgery training in India during the COVID-19 pandemic: straight from the horse's mouth.

OBJECTIVE: The COVID-19 pandemic has forced medical professionals throughout the world to adapt to the changing medical scenario. The objective of this survey was to assess the change in neurosurgical training in India following the COVID-19 pandemic. METHODS: Between May 7, 2020, and May 16, 2020, a validated questionnaire was circulated among neurosurgical residents across India by social media, regarding changes in the department's functioning, patient interaction, surgical exposure, changes in academics, and fears and apprehensions associated with the pandemic. The responses were kept anonymous and were analyzed for changes during the COVID-19 pandemic compared to before the pandemic. RESULTS: A total of 118 residents from 29 neurosurgical training programs across 17 states/union territories of the country gave their responses to the survey questionnaire. The survey revealed that the surgical exposure of neurosurgical residents has drastically reduced since the onset of the COVID-19 pandemic, from an average of 39.86 surgeries performed/assisted per month (median 30) to 12.31 per month (median 10), representing a decrease of 67.50%. The number of academic sessions has fallen from a median of 5 per week to 2 per week. The survey uncovered the lack of universal guidelines and homogeneity regarding preoperative COVID-19 testing. The survey also reveals reluctance toward detailed patient examinations since the COVID-19 outbreak. The majority of respondents felt that the COVID-19 pandemic will hamper their operative and clinical skills. Fear of rescheduling or deferring of licensing examinations was significantly higher among those closest to the examination (p = 0.002). CONCLUSIONS: The adverse impact of the pandemic on neurosurgical training needs to be addressed. While ensuring the safety of the residents, institutes and neurosurgical societies/bodies must take it upon themselves to ensure that their residents continue to learn and develop neurosurgical skills during these difficult times.
