Neuroborreliosis with intracranial hypertension and visual loss in a pediatric patient: illustrative case.

Background: Approximately 15% of Lyme disease cases involve the nervous system and are termed "neuroborreliosis." A rare complication of neuroborreliosis is idiopathic intracranial hypertension with resulting neurological deterioration. There are very few reports of this in the literature, most of which consist of case reports and small case series.

The impact of impaired insulin regulation on severity of SARS-CoV-2 infection: a 2-year retrospective single-center analysis.

Background: The COVID-19 pandemic has caused an international healthcare crisis and produced a large healthcare burden. Diabetes mellitus (DM) is a common disease that can be controlled via pharmacologic agents; however, many patients have poor glycemic control, leading to disease-related complications. DM has been reported in the literature to be associated with increasing morbidity and mortality in COVID-19 patients.

ABO blood group and rhesus factor association with inpatient COVID-19 mortality and severity: a two-year retrospective review.

Background: Early reports have indicated a relationship between ABO and rhesus blood group types and infection with SARS-CoV-2. We aim to examine blood group type associations with COVID-19 mortality and disease severity.

Methods: This is a retrospective chart review of patients ages 18 years or older admitted to the hospital with COVID-19 between January 2020 and December 2021.

Utilization of Portable Brain Magnetic Resonance Imaging in an Acute Care Setting.

Background Magnetic resonance imaging (MRI) is an important noninvasive diagnostic tool used in multiple facets of medicine, especially in the assessment of the neurological system with increasing usage over the past decades. Advancement in technology has led to the creation of portable MRI (pMRI) that was cleared for use recently. Methodology A prospectively collected retrospective study was conducted at a single institution to include patients aged >18 years, admitted to the hospital, and requiring MRI for any brain pathology.

The Evaluation of Skin Turgor in Relation to Changes in Intracranial Pressure in Patients After Decompressive Hemicraniectomy.

Introduction Decompressive hemicraniectomies have been the mainstay of treating medically refractory elevated intracranial pressures (ICPs). Afterward, ICP continues to be monitored. However, the reliability of monitoring the ICP in a patient after craniectomy has been shown to be variable, at best.

Thoracic Pedicle Screw Placement Utilizing Hands-On Training Session on Three-Dimensional Models.

The utilization of three-dimensional (3D) models has been an important element of medical education. We demonstrate a three-dimensionally-printed (3DP) thoracic spine model for use in the teaching of freehand pedicle screw placement. Neurosurgical residents with varying years of experience practiced screw placement on these models.

Changing Frequency of the Use of Intraoperative Equipment Among Neurosurgeons, Neurosurgery Residency Faculty, and Neurosurgery Residents.

Neurosurgical procedures have relied on the use of various intraoperative equipment since its advent. These include an operative microscope, ultrasound, and loupes with a headlight. The necessity of these pieces of equipment makes them vital in the training of residents as well.

Novel Bedside Utilization of Foley Catheter in the Emergent Removal of Colorectal Foreign Body: A Case Report and Literature Review.

Rectal foreign bodies (RFBs) present unique challenges to the emergency physician. Failure to emergently remove the RFB may lead to additional intraoperative procedures with increased likelihood of complications. We present a case of retained RFB in the emergency department, in which the usual standard approaches to transanal removal had failed.

A Reassessment of Weaning Parameters in Patients With Spontaneous Intracerebral Hemorrhage.

Background and purpose Patients with spontaneous intracerebral haemorrhage have significant morbidity and mortality. One aspect of their care is the need for mechanical ventilation. Extubating a patient safely and efficiently is important in advancing their care; however, traditional extubation criteria using the rapid shallow breathing index and negative inspiratory force do not predict success in these patients as well as they do in other intubated patients.

The Penn Classification Predicts Hospital Mortality in Acute Stanford Type A and Type B Aortic Dissections.

Objectives: Mortality in acute aortic dissection varies depending on anatomic location, extent, and associated complications. The Stanford classification guides surgical versus medical management. The Penn classification stratifies mortality risk in patients with Stanford type A aortic dissections undergoing surgery.

Speeding the Detection of Vessel Cannulation: An In-Vitro Stimulation Study.

Background: Some practitioners "prime" small IV angiocatheter needles with 0.9% sodium chloride-claiming this modification speeds visual detection of blood in the angiocatheter flash chamber on vessel cannulation.

Methods: We compared the time required for human blood to travel the length of saline-primed and saline-unprimed 24- and 22-gauge angiocatheter needles (Introcan Safety IV Catheter; B.

Role of calcification in the outcomes of treated, unruptured, intracerebral aneurysms.

Purpose: This study examined clinical and aneurysm characteristics in patients with unruptured aneurysms, treated with either coiling or clipping at a single institution, with the primary outcome-Glasgow Outcome Score (GOS)-measured at 6 months after treatment.

Methods: Data was obtained by a retrospective review of a prospective registry of consecutive cases of unruptured intracranial aneurysms treated at a single institution from 2002 to mid 2007. Demographic data, number, location, and size of aneurysms, calcification, mode of treatment, ASA score, presence of a stroke on post-op imaging, and GOS were recorded.

Endovascular mechanical retrieval of a terminal internal carotid artery breast tumor embolus.

The authors report the case of an acute left middle cerebral artery distribution stroke caused by a terminal internal carotid artery occlusion in a patient who underwent endovascular mechanical embolectomy. Histopathological analysis of embolic material obtained from the mechanical retriever device was diagnostic of a high-grade phyllodes breast tumor. This case represents the first instance, to our knowledge, of tumor embolus extraction via mechanical retrieval during acute ischemic stroke intervention.

Hydrogel coil-related delayed hydrocephalus in patients with unruptured aneurysms.

Object: Because of high recanalization rates associated with wide-necked intracranial aneurysms treated with bare platinum coils, hydrogel coils (HydroCoil, MicroVention, Inc.) have been developed. Hydrogel coils undergo progressive expansion once exposed to the physiological environment of blood and increase overall aneurysm filling.
