An Unusual Presentation of Cryoglobulinemia in a Patient With Undiagnosed Sjögren's Syndrome and Treated Marginal Zone Lymphoma.

Our case details a 47-year-old female who presented to our cancer hospital with a petechial rash of the lower extremities as well as a headache and blurred vision for the prior two days. She was found to have systolic pressures in the 200s in the emergency department and was admitted for a hypertensive emergency. Notable medical history includes marginal zone lymphoma (MZL) status post-submandibular resection at an outside institution in 11/2017 (thought to be in remission).

Decreased incidence of venous thromboembolism after spine surgery with early multimodal prophylaxis: Clinical article.

Object: Venous thromboembolism (VTE) represents a significant complication after spine surgery, with reported rates as high as 2%-4%. Published institutional practices for VTE prophylaxis are highly variable. In 2008, the authors implemented a departmental protocol for early VTE prophylaxis consisting of combined compressive devices and subcutaneous heparin initiated either preoperatively or on the same day of surgery.

Mixed-reality simulation for neurosurgical procedures.

Background: Surgical education is moving rapidly to the use of simulation for technical training of residents and maintenance or upgrading of surgical skills in clinical practice. To optimize the learning exercise, it is essential that both visual and haptic cues are presented to best present a real-world experience. Many systems attempt to achieve this goal through a total virtual interface.

Temporary percutaneous pedicle screw fixation for treatment of thoracolumbar injuries in young adults.

Objective: Bone-only injuries of the spine, including Chance fractures, are commonly managed nonoperatively. However, selected patients may benefit from surgical stabilization. In this report, the authors describe a method of temporary internal fixation with percutaneous pedicle screws for patients with intractable pain and thoracolumbar fractures.

Use of CT-based intraoperative spinal navigation: management of radiation exposure to operator, staff, and patients.

Objective: Radiation exposure represents significant risk to both operating room health care workers and their patients. The commonplace surgical implantation of spinal instrumentation often relies on fluoroscopy for guidance and verification. Advances in computerized tomography (CT)-based intraoperative navigation have improved accuracy of screw placement.

Vertebral brown tumors causing neurologic compromise.

Objective: Brown tumors are nonneoplastic lesions that occur only in the setting of hyperparathyroidism. Although vertebral brown tumors are relatively rare pathologic entities, their incidence seems to be on the rise, as evidenced by multiple case reports published during the past four decades. An extensive review of these lesions is lacking in the literature.

The central nervous system solitary fibrous tumor: a review of clinical, imaging and pathologic findings among all reported cases from 1996 to 2010.

Objective: Central nervous system (CNS) solitary fibrous tumor (SFT) is a rare lesion first identified as a unique entity in 1996. We describe two cases treated at the University of Florida followed by a review of all reported cases of CNS SFT between 1996 and 2010.

Methods: A review of the literature was performed to identify all reported cases of CNS SFT.
