<b><i>Background:</i></b> Deep brain stimulation (DBS) for Parkinson's disease (PD) has traditionally been performed in awake patients. Some patients are unable to tolerate surgery or extensive time off their medication allow neurophysiological testing during traditional DBS implantation, which previously limited surgical options these Recently, asleep image-guided lead placement using intraoperative MRI CT verification proposed as an alternative unwilling undergo...
Background Barriers to childhood immunization in Lebanon are multifaceted. While has historically maintained high coverage, recent socio-economic challenges and recurrent political crisis have strained the healthcare system, leading decreased vaccination rates. The knowledge, attitudes, practices (KAP) of mothers play a key role determining whether their children receive recommended immunizations. aim this study was assess KAP Lebanese regarding identify potential barriers children. Methods...
The aim of this study was to examine the role intraoperative neuromonitoring (IONM) during resection benign peripheral nerve sheath tumors in achieving gross-total (GTR) and reducing postoperative neurological complications.
OBJECTIVEVentricular shunts have an unacceptably high failure rate, which approaches 50% of patients at 2 years. Most shunt failures are related to ventricular catheter obstruction. The literature suggests that obstructions caused by in-growth choroid plexus and/or reactive cellular aggregation. authors report endoscopic evidence overdrainage-related tissue protrusions ("ependymal bands") cause partial or complete obstruction the catheter.METHODSA retrospective review was completed on...
Benign expansion of the subarachnoid spaces (BESS) is a condition seen in macrocephalic infants. BESS associated with mild developmental delays which tend to resolve within few years. It accepted that patients are at increased risk spontaneous subdural hematomas (SDHs), although exact pathophysiology not well understood. The prevalence SDH poorly defined, only large single-center series published. In this study authors aimed better define and outcomes through longitudinal review cohort...
Abstract The model of thermosolutal convection in a fluid‐saturated bidisperse porous medium Darcy type is studied this paper. permeability allowed to be horizontally isotropic for both the macro‐ and microphases. linear instability nonlinear stability are analyzed by taking Soret effect into account. Furthermore, anisotropy parameter, coefficient, other physical parameters on system investigated. It shown that boundaries energy do not coincide when layer heated salted from below, where...
Cervical spine injuries are the most common in pediatric population. The authors present youngest known patient who underwent cervical fusion to repair birth trauma–induced fracture dislocation, resulting spondyloptosis and spinal cord injury. A 2-week-old boy was found have injury after concerns arose from reduced movement of extremities. patient’s complicated by undiagnosed abdominal dystocia, which led distraction At 15 days age, successful C-5 corpectomy, with anterior C4–6 posterior...
Background: The rarity of skull base pathologies necessitates multicenter data to study them effectively. One method achieve this is the use de-identified nationwide insurance databases. A major strength such databases large number otherwise rare cases that can be identified using diagnosis or procedure codes, which may increase relevance findings and aid in statistical analysis.
Abstract INTRODUCTION Stereotactic brain biopsies (SBB) are critical for diagnosing neoplastic central nervous system pathologies including gliomas, metastatic carcinomas (cA), and lymphomas. While SBB-related complications have been cited in the literature, we sought to characterize perioperative risk factors/outcomes. METHODS We conducted a retrospective review of 615 patients who underwent SBB at same tertiary academic hospital between 2000-2020. Logistic regression was across all...
Elizabeth Crosby (1888-1983) is a beloved and well-respected titan of neuroanatomy. Her contributions to our understanding neuroanatomy are rooted in her seminal text, The Comparative Anatomy the Nervous System Vertebrates, Including Man, published 1936, which masterful comprehensive account comparative later texts, Correlative Neurosurgery System, standard reference texts this day. mentorship graduate students, close work with University Michigan neurosurgery department, quality research...
Objective: The transsphenoidal approach is the most commonly used method for pituitary adenoma resection. We aim to use a nationwide private insurance database evaluate practices across country, specifically temporal trends, antibiotic use, and postoperative infectious outcomes.
Basilar artery occlusion (BAO) is a rare cause of stroke associated with significant morbidity and mortality. It most frequently thromboembolic in nature, but may be caused by vertebral dissection. We present case BAO 36-year-old woman Alport syndrome. She was treated emergent thrombectomy via the right return to baseline neurological status. Her clinical status deteriorated later same day she found have re-occlusion. Repeat complicated persistent re-occlusion requiring 7 passes achieve...
Optimization of deep brain stimulation (DBS) parameters is a weeks to months-long process for many patients, due in part the inflammatory response caused by electrode implantation. To investigate effect inflammation on current delivery. transgenic mice, expressing Thy1-GCaMP6f (a genetically-encoded calcium sensor), were implanted with DBS subthalamic nucleus (STN). Immediately following insertion, high frequency electrical STN was performed and we imaged changes fluorescence elicited...
Transnasal access to the anterior skull base provides a minimally invasive approach for sellar and parasellar masses compared its open counterparts. The unique microbiome of sinonasal mucosa distinct challenges not encountered with other cranial approaches. use antibiotics in these cases has been standardized, data remain scarce regarding infectious outcomes. We conducted multicenter retrospective analysis endoscopic endonasal approaches (hereafter EEA) patient characteristics outcomes,...
We recently conducted a multicenter retrospective review of patients undergoing endoscopic endonasal approach for parasellar tumors to evaluate the impact perioperative and postoperative antibiotics on infectious outcomes. As part value-based health care initiative by North American Skull Base Society (NASBS), it provided first skull base study evaluating this topic, with over 600 patients. obstacles encountered during design, setup, execution present improvements similar studies in future....
Gelatin sponges, such as Gelfoam, are used hemostatic agents during surgery and generally absorbed over the course of 4-6 weeks in most body cavities. The time dissolution Gelfoam sponges within cerebral ventricles has not been described.The authors present a case intraventricular migration after ventriculoperitoneal shunt placement 6-week-old infant. infant was imaged regularly placement, sponge persisted on all images until 11 months surgery. At no follow-up did patient have any symptoms...
