Superselective methohexital challenge prior to intracranial endovascular embolization.

Pharmacologic provocative testing (PT) and intraoperative neurophysiologic monitoring (IONM) both mitigate and predict risks associated with endovascular embolization procedures. We present a series of patients undergoing endovascular intracranial embolization predominantly for AVMs both under general anesthesia and awake with the use of IONM. We reviewed our database to identify all patients undergoing endovascular procedures between January 1, 2014 and January 1, 2016.

Positive pharmacologic provocative testing with methohexital during cerebral arteriovenous malformation embolization.

A middle-aged patient underwent staged endovascular embolization of a Spetzler-Martin grade V right parietal arteriovenous malformation(AVM).In the fifth endovascular embolization, after methohexital 10 mg injection into a right posterior choroidal artery feeding the AVM nidus, there was an immediate change in the electroencephalogram (EEG) with simultaneous loss of motor evoked potentials (MEPs) in the bilateral upper and lower extremities and a delayed change in somatosensory evoked potential responses (SSEPs). No embolization was made and procedure was terminated.

HIV, rods, and the muscles--a discussion about HIV-associated nemaline rod myopathy.

This case reports a 21-year-old, homosexual African-American male who presented to our facility with a two-week history of progressive proximal muscle weakness. Quadriceps muscle biopsy showed a diagnosis of Nemaline Rod Myopathy, the presenting disease of his HIV infection. A review of the literature shows 13 prior case reports of similar disease process, often as the presenting symptom of the HIV disease.

The spinal cord: a review of functional neuroanatomy.

The spinal cord controls the voluntary muscles of the trunk and limbs and receives sensory input from these areas. It extends from the medulla oblongata to the lower border of the first lumbar vertebra. A basic knowledge of spinal cord anatomy is essential for interpretation of clinical signs and symptoms and for understanding of pathologic processes involving the spinal cord.

Total Joint Arthroplasty in Patients with Obstructive Sleep Apnea: Strategies for Reduction of Perioperative Complications.

Obstructive sleep apnea (OSA) has been associated with increased risk for medical complications following total joint arthroplasty. Our institution employs postoperative precautions for OSA patients in an effort to minimize the impact of postoperative complications in this group. We performed this study to assess the effect of careful monitoring on postoperative complication rates in OSA patients.

Total knee arthroplasty in patients with fibromyalgia.

Fibromyalgia has recently emerged as a diagnosis of exclusion for patients with chronic, widespread pain. We investigated the influence of this comorbidity on outcomes of total knee arthroplasty (TKA). We matched 59 patients (90 knees) who underwent primary TKA with a diagnosis of fibromyalgia to control patients who underwent the same surgery.

Total hip arthroplasty after prior surgical treatment of hip fracture is it always challenging?

Salvage total hip arthroplasty (THA) presents a viable solution for failed open reduction internal fixation. This study compares salvage THA in patients with prior femoral neck fractures vs patients with prior intertrochanteric fractures. One hundred fifty-four hips in 152 patients underwent conversion from open reduction internal fixation to THA.

Perioperative stroke after total joint arthroplasty: prevalence, predictors, and outcome.

Background: The risk of perioperative stroke following cardiac and carotid artery surgery is well documented. There is an apparent lack of recognition and appreciation of this complication after total joint arthroplasty. The present study was designed to determine the prevalence of, and outcome after, perioperative stroke following total joint arthroplasty.

Is deep vein thrombosis a good proxy for pulmonary embolus?

It is assumed that prevention of deep venous thrombosis (DVT) is likely to lead to a reduction in the incidence of pulmonary embolus (PE). This study examines the association between symptomatic DVT and PE in patients undergoing orthopedic procedures. We reviewed medical records of 1495 patients who underwent evaluation for DVT or PE within 90 days of an index orthopedic procedure at our institution between 2004 and 2008.

Arthroscopy for labral tears in patients with developmental dysplasia of the hip: a cautionary note.

Patients with developmental dysplasia of the hip may present with acetabular rim overloading, labral hypertrophy, and tear. Our hypothesis was that isolated arthroscopic treatment of labral tear is likely to fail in most patients. We investigated 34 patients who underwent at least one arthroscopy of the hip for labral tear.

Benign splenic epithelial cyst accompanied by elevated Ca 19-9 level: a case report.

We report the case of a 30-year-old woman with a benign epidermoid splenic cyst and a high CA 19-9 serum level (268 U/mL). The patient underwent resection of the cyst and splenectomy. After removal of the cyst, the serum CA 19-9 level decreased to a normal level within 6 weeks.
