Nonfermenting bacteria are ubiquitous environmental opportunists that cause infections in humans, especially compromised patients. Due to their limited biochemical reactivity and different morphotypes, misidentification by classical phenotypic means occurs frequently. Therefore, we evaluated the use of matrix-assisted laser desorption(More)
The authors present a rare case of lipoma of the sylvian fissure found in a 34-year-old man who presented with seizures. The patient underwent craniotomy and an attempted resection of the lesion, which was initially believed to be a dermoid tumor. The imaging characteristics of dermoids and lipomas are extremely similar. Given the difference in the natural(More)
This study was done to examine the criteria for determining the adequacy of preoperative total parenteral nutrition (TPN). We hypothesized that an important criterion for adequate preoperative nutrition should be a contraction of the expanded extracellular fluid compartment known to occur in malnourished patients undergoing surgical treatment. Clinical(More)
Malnutrition in surgical patients is associated with an increased incidence of postoperative mortality and morbidity. Preoperative nutritional support has been shown to be efficacious in reducing the incidence of these complications, although the postoperative complication rate in these patients continues to be greater than in their wellnourished(More)
This study is a retrospective review of the effect of nutritional support on duration of hospitalization in patients undergoing radical cystectomy. Thirty-five patients were randomly assigned to receive either 5% dextrose (D5W) solution plus electrolytes or total parenteral nutrition (TPN) following operation. The assigned nutritional regimen was continued(More)
Meningeal melanocytoma is a rare pigmented tumor originating from the melanocytes that generally occurs in the posterior fossa and the spinal cord. Although it is known as a relatively benign tumor, some recurrences have been reported. We report two cases of spinal meningeal melanocytoma with immunohistochemical and ultrastructural studies. In addition, we(More)
Patients with epilepsia partialis continua may develop progressive neurological deficits of unclear origin. It is possible that repetitive epileptic spikes induce plastic changes in the cortex analogous to the changes observed following direct microstimulation. A child is reported with focal cortical dysplasia, intractable focal seizures, worsening(More)
OBJECTIVE To describe the neuropathologic findings and clinical course of 2 patients who underwent temporal lobectomy for medically refractive epilepsy and were later found to have high anti-glutamic acid decarboxylase (GAD) concentrations. METHODS Small case series. RESULTS Neuropathologic examination of both patients revealed International League(More)
Changes in serum albumin levels and body weight are often used as indicators of the efficiency of a nutritional support regimen. Patients with moderate nutritional depletion demonstrate two distinct patterns of response during refeeding. The first is characterized by a decrease in the previously expanded extracellular fluid space with a rise in serum(More)
OBJECTIVE Dural metastases and meningiomas are extraaxial lesions that may be difficult to distinguish using conventional imaging methods. This distinction, however, is clinically important. Perfusion MRI may play a role in preoperative assessment. The aim of this study was to evaluate the utility of perfusion parameters in differentiating between these two(More)
