Intradural "limited drill" technique of anterior clinoidectomy and optic canal unroofing for microneurosurgical management of ophthalmic segment and PCOM aneurysms-review of surgical results.

To evaluate the safety and efficacy of intradural "limited drill" technique (ILDT) of anterior clinoidectomy (AC) and optic canal unroofing (OCU) for microneurosurgical management of ophthalmic segment and posterior communicating artery (PCOM) aneurysms. All the patients with ophthalmic segment and PCOM aneurysms who underwent AC and OCU by ILDT for microneurosurgical management of ophthalmic segment and PCOM aneurysms during 4-year period (2013-2016) at our Institute were included in this study. In ILDT of AC and OCU, the use of power drill is restricted to AC only and OCU is done exclusively with 1-mm Kerrison punch.

Safety and Accuracy of Anatomic and Lateral Fluoroscopic-Guided Placement of C2 Pars/Pedicle Screws and C1 Lateral Mass Screws, and Freehand Placement of C2 Laminar Screws.

Objective: To evaluate the safety and accuracy of anatomic- and lateral fluoroscopic-guided placement of C2 pars/pedicle, C1 lateral mass screws, and freehand placement of C2 laminar screws.

Methods: All the patients who underwent posterior cervical/occipitocervical fixation that involved the placement of C1/C2 screws during a 5-year period (2011-2015) at our institute were included in this study.

Results: C1/C2 screws were placed in a total of 94 patients during this period.

Comparison of telemedicine with in-person care for follow-up after elective neurosurgery: results of a cost-effectiveness analysis of 1200 patients using patient-perceived utility scores.

OBJECTIVE The utility of telemedicine (TM) in neurosurgery is underexplored, with most of the studies relating to teletrauma or telestroke programs. In this study, the authors evaluate the cost-effectiveness of TM consultations for follow-up care of a large population of patients who underwent neurosurgical procedures. METHODS A decision-analytical model was used to assess the cost-effectiveness of TM for elective post-neurosurgical care patients from a predominantly nonurban cohort in West Bengal, India.

Analogous Three-Dimensional Constructive Interference in Steady State Sequences Enhance the Utility of Three-Dimensional Time of Flight Magnetic Resonance Angiography in Delineating Lenticulostriate Arteries in Insular Gliomas: Evidence from a Prospective Clinicoradiologic Analysis of 48 Patients.

Background: Three-dimensional (3D) time of flight (TOF) imaging is the current gold standard for noninvasive, preoperative localization of lenticulostriate arteries (LSAs) in insular gliomas; however, the utility of this modality depends on tumor intensity.

Methods: Over a 3-year period, 48 consecutive patients with insular gliomas were prospectively evaluated. Location of LSAs and their relationship with the tumor were determined using a combination of contrast-enhanced coronal 3D TOF magnetic resonance angiography and coronal 3D constructive interference in steady state (CISS) sequences.

Pneumosinus dilatans of the spheno-ethmoidal complex associated with hypovitaminosis D causing bilateral optic canal stenosis.

Introduction: Pneumosinus dilatans (PSD) is a rare disorder of undetermined etiology characterized by expansion of the paranasal sinuses without bony erosion. Of the few cases of PSD described in indexed pediatric literature, there has been no reported case of this disorder presenting with optic canal stenosis in the setting of a vitamin deficiency.

Case Material: A 12-year-old girl presented with a 3-month history of progressive, painless, and asymmetric visual deterioration in her eyes.

Giant multi-compartmental suprasellar Rathke's cleft cyst with restriction on diffusion weighted images.

Rathke's cleft cysts are congenital lesions seen in sellar-suprasellar regions. We report a case of giant Rathke cyst in a 43-year-old patient with multi-compartmental involvement who presented with seizures with almost normal visual acuity. We discuss radiological and pathological features of various differential diagnoses for the giant suprasellar Rathke's cyst.

Paraspinal muscle morphometry in cervical spondylotic myelopathy and its implications in clinicoradiological outcomes following central corpectomy: clinical article.

Object: The objective of this study was to assess the cross-sectional areas (CSAs) of the superficial, deep flexor (DF), and deep extensor (DE) paraspinal muscles in patients with cervical spondylotic myelopathy (CSM), and to evaluate their correlations with functional status and sagittal spinal alignment changes following central corpectomy with fusion and plating.

Methods: In this retrospective study of 67 patients who underwent central corpectomy with fusion and plating for CSM, the CSAs of the paraspinal muscles were calculated on the preoperative T2-weighted axial MR images and computed as ratios with respect to the corresponding vertebral body areas (VBAs) and as flexor/extensor CSA ratios. These ratios were then compared with those in the normative population and analyzed with respect to various clinicoradiological factors, including pain status, Nurick grade, and segmental angle change at follow-up (SACF).

Subgaleo-peritoneal shunt: An effective and safer alternative to lumboperitoneal shunt in the management of persistent or recurrent iatrogenic cranial pseudomeningoceles.

Subgaleo-peritoneal (SP) shunting for pseudomeningoceles (PMCs) is an effective and safer alternative as compared to the lumboperitoneal (LP) shunt. SP shunting was done in six patients (14-60 years) with persistent or recurrent PMCs using the cranial (ventricular part) and the distal parts of a Chhabra shunt connected by a rigid connector without any intervening chamber or valve. Two patients had undergone a prior LP shunt that had failed.

Solitary thoracic vertebral body cysticercosis presenting with progressive compressive myelopathy.

Common bony spinal pathologies that could present with progressive spasticity include vertebral body tumors or chronic infections of the spine. Cysticercosis of the spine commonly has an intramedullary occurrence. The authors discuss the presentation and management of a rare case of solitary vertebral cysticercosis that presented with lower-limb spasticity and sphincter involvement.

Elderly Indo-Caribbean Hindus and end-of-life care: a community-based exploratory study.

America's increasingly diverse older population needs clinicians to be familiar with ethnic and cultural issues pertaining to end-of-life care (EOLC). Although there has been some work addressing these issues among African-American, Hispanic-American, and some Asian-American populations, data on the Asian-Indian and Hindu populations remain sparse. This community-based exploratory study surveyed older Indo-Caribbean Hindu people (a subset of the Hindu population living in America) attending a senior center in Queens, New York.

Attitudes of Asian-Indian Hindus toward end-of-life care.

The population of older adults in the United States is increasing in cultural diversity. Thus, an appreciation of cultural perspectives regarding end-of-life care may benefit practicing physicians. This article addresses end-of-life care issues from the perspective of Hinduism--a faith embraced by a growing demographic of the U.
