Endoscopic Endonasal Transsphenoidal Surgery for Patients with Prolactinomas: Indications and Outcomes.

Objective: Clinical paradigms and consensus recommend dopamine agonists (DAs) as the primary treatment for prolactinomas. However, medically treated patients also encounter challenges such as DA resistance, intolerable side effects, and recurrence of hyperprolactinemia after DA withdrawal. Technical advances in transsphenoidal resection, with an endoscopic endonasal approach, have led to improved visualization of tumor, decreased postoperative morbidity, and shortened length of stay.

A Remarkable Response of Granulomatous Hypophysitis to Infliximab in a Patient With a Background of Crohn's Disease-A Case Report.

Hypophysitis is primary or idiopathic or secondary to another disease process. The histologic subtypes of hypophysitis are lymphocytic, granulomatous, xanthomatous, xanthogranulomatous, or IgG4-related. Granulomatous hypophysitis is the second most common form and is characterized by multinucleated giant cells with granulomas and histiocytes.

An Effective and Practical Fluid Restriction Protocol to Decrease the Risk of Hyponatremia and Readmissions After Transsphenoidal Surgery.

Background: Delayed hyponatremia is a common complication following transsphenoidal surgery (TSS) of pituitary lesions, which leads to significant patient morbidity, as well as increased hospital costs associated with readmission.

Objective: To report the effects of fluid restriction, during a postoperative period of 4 d, to decrease rates and readmissions for hyponatremia in a cohort of patients undergoing TSS.

Methods: Because of our observed postoperative rates of hyponatremia, we implemented 1000-mL fluid restriction limited to postoperative days (POD) 4 to 8 in consecutive patients undergoing surgery at our center between March 2018 and January 2019.

Molecular profiling predicts meningioma recurrence and reveals loss of DREAM complex repression in aggressive tumors.

Meningiomas account for one-third of all primary brain tumors. Although typically benign, about 20% of meningiomas are aggressive, and despite the rigor of the current histopathological classification system there remains considerable uncertainty in predicting tumor behavior. Here, we analyzed 160 tumors from all 3 World Health Organization (WHO) grades (I through III) using clinical, gene expression, and sequencing data.

Intraoperative Computed Tomography Angiography: A Novel Completion Imaging Modality for Carotid Endarterectomy.

Background: Intraoperative computed tomography angiography (ICTA) is a novel completion imaging modality for carotid endarterectomy (CEA). No studies exist in the literature describing ICTA use in CEA.

Objective: To evaluate the feasibility and efficacy of ICTA as a method of immediately evaluating the technical results of CEA.

Does preoperative scalp shaving result in fewer postoperative wound infections when compared with no scalp shaving? A systematic review.

Preoperative scalp shaving has been a well-established practice among neurosurgeons based on the belief that hair removal prevents postoperative infections. Apart from aiding in improved visualization of the incision line, ease of closure, and dressing application, there are concerns that the presence of hair at the surgical site may interfere with the surgical procedure. Preoperative scalp shaving is a controversial practice, and many neurosurgeons are moving toward not removing any hair or clipping minimal hair along the incision line rather than shaving the scalp.

Nurses' perceptions of open visiting hours in neuroscience intensive care unit.

A quality improvement project was undertaken by Neuro-ICU nurses to determine possible effects from open visitation. From a quality improvement perspective, nurses' concerns were investigated along with their perceptions about open visitation to determine a need for visitation policy revision. Vast variability in nurses' interpretation and implementation of individualized open visitation policy suggested a need for the following: staff education about the policy and its implementation, a review of the literature to determine the validity of concerns about deleterious physiologic effects on neuroscience patients from visitation, and improved communication among nurses about visitation.

Pentobarbital sodium coma for refractory intracranial hypertension.

Refractory intracranial hypertension (RICH) is defined as intracranial pressures that exceed 25 mm Hg for 30 minutes, 30 mm Hg for 15 minutes, or 40 mm Hg for 1 minute. RICH occurs in approximately 15% of patients with traumatic brain injury. If it is not aggressively treated, RICH can result in cerebral herniation and death.
