The importance of social networks in neurosurgery training in low/middle income countries.

Introduction: Neurosurgery is evolving with new techniques and technologies, relies heavily on high-quality education and training. Social networks like Twitter, Facebook, Instagram and LinkedIn have become integral to this training. These platforms enable sharing of surgical experiences, fostering global knowledge-sharing and collaboration among neurosurgeons. Virtual conferences and courses are accessible, enhancing learning regardless of location. While these networks offer real-time communication and collaborative opportunities, they also pose challenges like the spread of misinformation and potential distractions. According to the PICO format, the target population (P) for the purpose of this paper are medical students, neurosurgical residents and consultants on the role of social media (I) in neurosurgery among Low-Middle income countries (C) with the main outcome to understand the collaborative domain of learning. Material and method: This cross-sectional survey, conducted in June-July 2023, involved 210 medical students, neurosurgery residents, fellows, and practicing neurosurgeons from low and middle-income countries. A structured questionnaire assessed social network usage for neurosurgery training, covering demographic details, usage frequency, and purposes like education, collaboration, and communication. Participants rated these platforms' effectiveness in training on a 1-5 scale. Data collection employed emails, social media groups, and direct messaging, assuring respondent anonymity. The survey aimed to understand and improve social networks' use in neurosurgery, focusing on professional development, challenges, and future potential in training. Results: In a survey of 210 participants from low and middle-income countries, 85.5% were male, 14.5% female, with diverse roles: 42.9% neurosurgery residents, 40% practicing neurosurgeons, 14.6% medical students, and 2.4% other healthcare professionals. Experience ranged from 0 to 35 years, with Mexico, Nigeria, and Kenya being the top participating countries. Most respondents rated neurosurgery training resources in their countries as poor or very poor. 88.7% used social media professionally, predominantly WhatsApp and YouTube. Content focused on surgical videos, research papers, and webinars. Concerns included information quality and data privacy. Interactive case discussions, webinars, and lectures were preferred resources, and most see a future role for social media in neurosurgery training. Conclusions: Our study underscores the crucial role of social media in neurosurgery training and practice in low and middle-income countries (LMICs). Key resources include surgical videos, research papers, and webinars. While social media offers a cost-effective, global knowledge-sharing platform, challenges like limited internet access, digital literacy, and misinformation risks remain significant in these regions.

Cervical Spinal Cord Herniation After Laminectomy.

Following a recent cervical laminectomy, a 67-year-old female patient developed neck pain and torticollis after a coughing episode. On physical examination, manifestations of neck pain, stiffness, and 4/5 quadriparesis were noted. Magnetic resonance imaging findings indicated the presence of herniation of the cervical medulla, accompanied by cerebrospinal fluid leakage. Consequently, surgical intervention was performed to reposition the herniated cord within its original subarachnoid space, thereby averting potential recurrence. The patient experienced complete resolution of symptoms within a few days postoperatively. It is important to recognize that postoperative cervical spinal cord herniation following laminectomy is an infrequent complication that manifests with a delayed onset. Surgical repair serves as the main therapeutic modality.

Early Experience of Endoscopic Endonasal Transphenoidal Surgery for Pituitary Adenoma: Preliminary Report of 56 Cases Operated in a West African Institution.

BACKGROUND: Although endoscopic endonasal approach (EEA) has been popularized worldwide for pituitary adenoma surgery, in sub-Saharan Africa, neurosurgeons are still only starting their experience with it. This study was designed to assess the early results of EEA for pituitary adenoma from an under-equipped environment, namely, the Department of Neurosurgery of the Teaching Hospital of Yopougon Abidjan and Bouaké in Ivory Coast. METHODS: The data of 56 cases of EEA for pituitary adenoma surgery performed between 2016 and March 2019 at the Teaching Hospital of Yopougon-Abidjan and Bouaké were retrospectively assessed. Pre- and postoperative neuro-ophthalmologic and hormonal status were analyzed. Moreover, the quality of tumor removal, and pre- and postoperative complications were also evaluated. RESULTS: In this study, there were nonfunctional adenomas (20), prolactinoma (18), Cushing disease (9), and acromegaly (3). A reduced visual acuity and/or visual field defect was observed in 49 cases. The mean operation time was 225 ± 94.7 minutes. The tumor removals were complete in 57.14%, subtotal in 35.71%, and partial in 7.14%. These led to a visual improvement in 69.64%. Postoperative complications were cerebrospinal fluid leaks (19.64%), diabetes insipidus (12.50%), visual worsening (7.14%), meningitis (3.57%), and carotid injury (3.57%) that led to death. CONCLUSIONS: This study represents the early surgical experience using EEA for treating pituitary adenoma in an under-equipped environment. Although the postoperative complication rate was relatively high, refinements of local surgeons' technique would lead to a better patient outcome.

Microsurgical Anatomy of the Labyrinthine Artery and Clinical Relevance.

AIM: To describe the origin, the course, and relationships of the labyrinthine artery (LA). MATERIAL AND METHODS: Thanks to a colored silicone mix preparation, ten cranial bases were examined using x3 to x40 magnification under surgical microscope. RESULTS: The LA often arose from the meatal loop of the anterior inferior cerebellar artery (AICA) (90%), or basilar artery (10%). The loop was extra-meatal of the internal auditory meatus (IAM) in 30%, at the opening of the internal auditory meatus in 20%, or intra-meatal in 35%. The AICA coursed in closed relationship to the VII and VIII cranial nerves. It coursed between VII and VIII cranial nerve roots in 85%, or passed over the ventral side of both VII and VIII cranial nerve. The average diameter of the LA was 0.2 +/- 0.05 mm. LA was single trunk in 60%, and bi-arterial in 40%. CONCLUSION: The implication of these anatomic findings for cerebello-pontine angle tumors surgery and neurovascular pathology such as infarction, aneurysm of the LA or the AICA are reviewed and discussed.

A rare third ventricle solitary tuberculoma.

The localization of the tuberculoma at the third ventricle is rare. The authors report a case of third ventricle solitary Tuberculoma which has occurred in a 10 year old patient and revealed by a syndrome of intracranial hypertension without tuberculosis stigma. This lesion appears clinically and radiologically as a primary brain tumor. A total removal using a subchoroidal approach to the third ventricle has been performed. Histological examination showed a tuberculous like granuloma. An adjuvant antituberculous chemotherapy practiced for 6 months brought the complete cure. The authors insist on the diagnostic and therapeutic difficulties in front of a third ventricle solitary tuberculoma.

Microsurgical anatomy of distal medial striate artery (recurrent artery of Heubner).

INTRODUCTION: In literature, many controversies exist about courses and terminology of the distal medial striate artery (DMSA) or recurrent artery first described by Heubner near 1872. The purpose of this study was to define the accurate anatomy of this artery, to help the practitioners during surgery of the anterior cerebral-anterior communicating arteries (ACA-ACoA) complex. MATERIALS AND METHODS: 20 cranial bases were examined using magnification of the surgical microscope. One half for which the internal carotid arteries and internal jugular veins were dissected, cannulated and perfused with colored silicon on fresh cadavers; the other half only with arterial injection of formalin-fixed normal adult human brains. RESULTS: The artery arose principally from A2 segment (58%), always less than 5 mm up to downstream from ACA to ACoA junction. In 59.5% it had a recurrent course anterior to A1 segment. It terminated in one to three stems which entered the medial part of the anterior perforated substance. The DMSA was present as a single vessel in 95% of cases. Its main outer diameter was 0.7 mm and the length had an average of 24 mm. CONCLUSION: Iatrogenic damage or occlusion leads to a mediobasal striatum infarction with important neurological deficits such as brachiofacial hemiparesis and aphasia. This artery should be routinely identified during clipping of ACoA aneurysm. Special attention in this study was given to atypical posterior course or anatomic variations such as double DMSA on a same side.
