BACKGROUND CONTEXT Somatosensory evoked potential (SSEP) is used to monitor integrity of the brain, spinal cord, and nerve roots during spinal surgery. It records the electrical potentials from the scalp after electrical stimulation of the peripheral nerves of the upper or lower limbs. The standard monitoring modality in lumbosacral spine surgery includes… (More)
Outpatient spine surgery is becoming popular because of its substantial economic advantages. We retrospectively studied 97 spine surgery outpatients and 578 inpatients who had proceeded through a common process of surgical venue selection. No differences (p > 0.05) were found in gender, race, obesity rate (46.9% versus [vs.] 42.9%), hypertension (9.7% vs.… (More)
BACKGROUND After an aneurysmal subarachnoid hemorrhage, cerebral microcirculatory changes occur as a result cerebral vasospasm. The objective of this study is to investigate, with a computational model, how various degrees of vasospasm are influenced by increasing the mean blood pressure and decreasing the blood viscosity. METHODS Using ANSYS CFX… (More)
Renal cell carcinoma is an uncommon type of cancer that rarely metastasizes to the brain. The prognosis after discovering brain metastasis has traditionally been dismal. We are presenting a case of renal cell carcinoma with multiple brain metastases that was successfully treated with multimodal therapy including a new type of medication.
Endometriosis may in severe cases lead to obliteration of the anterior and/or posterior cul-de-sacs in the female pelvis. The anterior cul-de-sac is generally less commonly affected. This type of cases usually presents a challenge for the operating surgeon, whether via open route or through laparoscopy. In this paper, we present an illustrative case and… (More)
Cornual (interstitial) ectopic pregnancy is an uncommon variant of ectopic pregnancy which often poses a diagnostic and therapeutic challenge with a significant risk of rupturing and bleeding. We present a ruptured right cornual pregnancy and explain how to deal with such a case laparoscopically.
OBJECT Comorbidities in patients undergoing spine surgery may reasonably be factors that increase health care costs. To verify this hypothesis, the authors conducted the following study. METHODS Major comorbidities and age-adjusted Charlson Comorbidity Index scores were retrospectively analyzed for 816 patients who underwent spine surgery at the authors'… (More)
GOAL To study the interaction of obesity and age in patients with multiple spine surgeries. METHODS Data on the body mass index (BMI) of 956 patients were collected and classified into four groups: non-obese (BMI <30 kg/m(2)), obese-class I (BMI ≥30 kg/m(2)), obese-class II (BMI ≥35 kg/m(2)) and obese-class III (BMI ≥40 kg/m(2)). Patients' age was… (More)
INTRODUCTION Degenerative spine disorders are steadily increasing parallel to the aging of the population with considerable impact on cost and productivity. In this paper we study the prevalence and risk factors for multiple spine surgery and its impact on cost. METHODS Data on 1,153 spine surgery inpatients operated between October 2005 and September… (More)
Uterine lipoleiomyomas are rare benign tumors that mostly affect the uterine corpus. We are reporting the imaging and operative procedure of a very rare case of a large lipoleiomyoma of the uterine cervix combined with an occult adult ovarian granulosa cell tumor. The patient was treated with minimal invasive surgery.
