Endosonographic features that are thought to characterize lymph node metastasis were evaluated in 100 patients with esophageal carcinoma. Subjects underwent preoperative endoscopic ultrasonography to assess depth of tumor invasion (T stage) and lymph node metastasis (N stage). Endosonographically imaged lymph nodes were evaluated according to the following(More)
Primary angiitis of the central nervous system has until recently been considered rare, usually progressive, and untreatable. In 1987, preliminary diagnostic criteria for the disorder were proposed in the hope of gaining a more accurate description of the disease. We used these criteria in reviewing all cases reported in the English language (99 cases) and(More)
We evaluated the accuracy and interobserver variability of selected ictal and postictal behavioral changes. Three observers, blinded to clinical history, EEG, and side of surgical resection, analyzed videotapes of 166 seizures in 38 patients, looking for lateralizing signs. Twenty-seven patients with temporal lobe resections were seizure-free for > or = 1(More)
Multiple sclerosis (MS) and other chronic illnesses can drastically decrease quality of life (QOL), but there has been little systematic study of QOL in patients with chronic medical diseases. We analyzed QOL in 68 patients with MS, 164 patients with inflammatory bowel disease, and 75 patients with rheumatoid arthritis. The previously validated test(More)
STUDY OBJECTIVE To demonstrate the utility of a new blood-conserving arterial line system in reducing blood loss associated with blood drawing in the critical care setting. DESIGN Prospective, randomized, crossover comparison between two arterial line systems. SETTING Medical intensive care unit (ICU); tertiary care teaching institution. PATIENTS(More)
OBJECTIVE Primary angiitis of the central nervous system (PACNS) has been considered a rare and highly fatal disorder when untreated. In recent years the disease has been increasingly diagnosed by cerebral angiography, often without histologic confirmation. We have questioned whether cases of PACNS diagnosed on the basis of angiography alone are equivalent(More)
Four hundred fifteen finger joints from 30 patients were evaluated for the presence of joint-space erosion, narrowing, and degenerative spurring on plain films, low-resolution digitized images (1024 x 840 bytes x 12 bit matrix), and high-resolution digitized images (2048 x 1680 bytes x 12 bit matrix). Three hundred four joints were abnormal. Low- and(More)
The purpose of this study was to examine the predictability of intrapair percentage differences of ultrasonic fetal biometric parameters in detecting twin discordancy. Fetal biometric parameters obtained in 90 twin gestations within 7 days of delivery were analyzed. Intrapair differences of 5% and 10% were used for biparietal diameter (BPD), head(More)
OBJECTIVE To assess the reliability and validity of the Medical Outcomes Study (MOS) Short Form Health Survey as an indicator for quality of life in patients with chronic headaches. DESIGN Patient interview survey. SETTING A headache clinic within a multi-specialty group practice. PATIENTS 208 consecutive patients seeking evaluation of headache at the(More)
BACKGROUND To analyze the differences in quality of life associated with headache diagnoses using the Medical Outcomes Study Short Form Health Survey (SF-20). METHODS A patient interview survey using the SF-20 Short Form Health Survey was conducted in a headache clinic within a multi-specialty group practice. All six health components of the SF-20 were(More)
