The application of medical ethics in the developing countries - A neurosurgical perspective.

Introduction: Neurosurgery is one of the rapidly evolving specialities of medical science, where the neurosurgeons have to provide evidence-based interventions in life threatening conditions maintaining the ethical standards.

Research Question: This narrative review sheds light on the current hindrances of the ethical aspects of neurosurgical practice in low and middle-income countries (LMICs) and provide some feasible solutions for future.

Material And Methods: A literature search was conducted using PubMed, Scopus and ISI web of knowledge focused on articles in English with the words "medical ethics" together with the words "neurosurgery", "ethical practice", "low and middle-income countries", "surgical innovation", "randomized clinical trials" and "outcome" alone or in combination.

Evaluation of computed tomography artefacts of carbon-fiber and titanium implants in patients with spinal oligometastatic disease undergoing stereotactic ablative radiotherapy.

This study evaluated artefacts on computed tomography (CT) images using Hounsfield units (HU) in patients with spinal oligometastatic disease who received carbon-fiber (CF; n = 11) or titanium (n = 11) spine implants and underwent stereotactic ablative radiotherapy (SABR). Pre- and postoperative HU were measured at the vertebral body, pedicle, and spinal cord at three different levels: the lower instrumented vertebra, the level of metastatic spinal cord compression, and an uninvolved level. Areas measured at each level were delicately matched pre- and postoperatively.

The current review aimed to summarize the global clinical characteristics of the COVID-19 patients systematically and identify their diagnostic challenges to help the medical practitioners properly diagnose and for better management of COVID-19 patients. We conducted a systematic search in PubMed, Web of Science, Scopus, Science Direct, and Google Scholar databases for original articles containing clinical information of COVID-19 published up to 7th May 2020.

Novel Surgical Treatment of Recurrent CSF Leak by Temporoparietal Temporalis Myofascial Flap: A Series of 6 Cases.

Background: With the advent of modern endoscopes and a better anatomic understanding of the skull base, the indications of endonasal approaches are increasing. These procedures may be complicated by high rates of postoperative cerebrospinal fluid (CSF) leak, and reconstruction of the defect remains challenging. In the anterior skull base, vascularized grafts have been reported as superior in preventing CSF leakage and infection.

Diabetes insipidus-an extremely rare complication from replacement of an external ventricular drain.

Insertion of an external ventricular drain (EVD) is one of the most common and most important lifesaving procedures encountered in the neurologic intensive care unit, but often done by the junior members of the team. A good number of complications may follow the insertion of EVD. In the available literature, only one case was reported with the placement of EVD in suprasellar cistern.

Use of Pulsed Radiofrequency Energy Device (PEAK Plasmablade) in Neuromodulation Implant Revisions.

Background: Battery replacement or revision surgery for neuromodulation implants is conventionally performed using sharp dissection. Meticulous dissection within thick scar tissue is vital to avoid damage to surrounding lead(s), which could result in more extensive revision surgery. Traditional electrosurgery devices are contraindicated as the emitted energy can be transferred to the hardware, resulting in implant or tissue damage with severe consequent complications.

Abdominal schwannoma in a case of neurofibromatosis type 2: A report of a rare combination.

Neurofibromatosis-2 (NF2) is an autosomal-dominant disease, which is characterized by vestibular schwannomas (VSs) (acoustic neurinoma) as well as tumours of the peripheral and central nervous system, demonstrating a variety of expression. A 12-year-old girl presented to us with headache and ataxia for four months. We examined and found a lump in the right side of her abdomen.

Avoidance and management of perioperative complications of endoscopic third ventriculostomy: the Dhaka experience.

Object: Although endoscopic third ventriculostomy (ETV) is a minimally invasive procedure, serious perioperative complications may occur due to the unique surgical maneuvers involved. In this paper the authors report the complications of elective and emergency ETV and their surgical management in 412 patients from July 2006 to October 2012 at Dhaka Medical College Hospital (a government hospital) and other private hospitals in Dhaka, Bangladesh. The authors attempted some previously undescribed simple maneuvers that may help to overcome the difficulties of managing complications.

Spinal cord herniation as a complication of en bloc, multilevel, anterior thoracic vertebrectomy for a giant cell tumor: success of posterior cord reduction and dural repair.

Iatrogenic spinal cord herniation is a rare complication following spinal stabilization surgery. The authors present a case of circumferential thoracic tumor decompression and fixation by anterior instrumentation complicated by delayed anterior spinal cord herniation. This complication resulted in progressive paraparesis 5 years after the original procedure.

Intracranial nonvestibular neurinomas: Young neurosurgeons' experience.

Background And Objectives: Neurinoma arising from other than nonvestibular cranial nerves is less prevalent. Here we present our experiences regarding the clinical profile, investigations, microneurosurgical management, and the outcome of nonvestibular cranial nerve neurinomas.

Materials And Methods: From January 2005 to December 2011, the recorded documents of operated nonvestibular intracranial neurinomas were retrospectively studied for clinical profile, investigations, microneurosurgical management, complications, follow-up, and outcomes.

Removal of cervical spinal tumor with large inferio-lateral extension through anterolateral (interscalene and transforaminal) approach.

Cervical spinal tumor with large lateral extension is usually removed through posterolateral approach and rarely through anterolateral approach. A young man presented with neck pain and brachialgia. Cervical spinal MRI showed a intraspinal tumor with huge extraforaminal paraspinal extension.

Surgical management of scalp arterio-venous malformation and scalp venous malformation: An experience of eleven cases.

Aims: Scalp arterio-venous malformation (AVM) and scalp venous malformation (SVM) are rare conditions that usually need surgical treatment. Here, we have reported our experience of the surgical management of such lesions with a short review of the literature.

Materials And Methods: In this prospective study, 11 patients with scalp AVM and SVM, who underwent surgical excision of lesion in our hospital from 2006 to 2012, were included.

Transcranial microsurgical and endoscopic endonasal cavernous sinus (CS) anatomy: a cadaveric study.

Aims And Objectives: Even in the era of tremendous microneurosurgical and endoscopic development, the cavernous sinus (CS) is a challenging anatomical site for a neurosurgeon. Many transcranial and a few endoscopic cadaveric studies have been done to study the CS; probably none were undertaken to study its microsurgical and endoscopic anatomy side by side. In this cadaveric study we perform a side-by-side comparison of the microsurgical and endoscopic anatomy of the CS that can help neurosurgeons deal with CS lesions more efficiently.

Endoscopic endonasal extended transsphenoidal removal of tuberculum sellae meningioma (TSM): an experience of six cases.

Aims: Tuberculum sellae meningiomas (TSMs) are usually removed through a transcranial approach. Recently, the sublabial transsphenoidal microscopic approach has been used to remove such tumours. More recently, endonasal extended transsphenoidal approach is getting popular for removal of tuberculum sellae meningioma.

Endoscopic endonasal transsphenoidal exposure of circle of Willis (CW); can it be applied in vascular neurosurgery in the near future? A cadaveric study of 26 cases.

Aim: Endonasal transsphenoidal approaches are getting rapidly popular in removing many midline skullbase lesions from crista galli to foramen magnum. For safe removal of these lesions, familiarity with endoscopic endonasal anatomy of circle of Willis is very important. Furthermore, for safe development of this approach in vascular neurosurgery in the near future, endoscopic endonasal exposure of circle of Willis is a fundamental step.

Bony reconstruction by reposition of bony chips in suboccipital craniectomy.

In suboccipital craniectomy where the bone is not repositioned, there may be a significant cosmetic defect due to lack of skull bone in the suboccipital region. It may accompanied by sensory symptoms, including pain. To prevent any cosmetic defect and sensory symptoms we repositioned the bone chips at the craniectomy site in 42 suboccipital craniectomies before the closure of the scalp.
