The National Wilms' Tumor Study, initiated in 1969, tested competing treatment strategems for patients with tumors ranging from Group (Gp) I (tumors confined to the kidney and totally removed) to Gp IV (remote metastases present at diagnosis). Three hundred and fifty-nine of 606 registered patients were randomized in the trial. Gp I patients under 2 years(More)
One-hundred-eighty-eight children up to 16 years of age were randomized in the second National Wilms' Tumor Study (NWTS) with tumors that were confined to the kidney and that had been totally excised (Group I). Most fared well whether treated for six or for 15 months with both actinomycin D (AMD) and vincristine (VCR). No postoperative radiation therapy(More)
The present study examined the effects of smoking on memory for prose passages. Habitual male smokers were matched on verbal ability, impulsivity level, and habitual smoking level and were instructed to smoke either a 0.1 mg (control), a 0.7 mg, or a 1.5 mg nicotine cigarette in a controlled fashion. Immediate recall after reading expository passages was(More)
Eighty male undergraduates were administered either glucose or 5, 10, 20, or 40 mg of hydrocortisone in a double-blind procedure. After 60 min they were asked to listen to eight 12 word lists and then asked to recall the words. In addition to the expected effects of rate of presentation, serial position, and practice there was a significant interaction(More)
The present study examined the effects of caffeine on memory for supraspan word lists. Twelve groups of male and female college students classified as high or low impulsive received either 0, 2, or 4 mg/kg of caffeine. Female subjects were tested only during the menstrual phase of their cycle and were not taking oral contraceptives. Subjects listened to 12(More)
The present study investigated the effects of ethanol on retrieval from long-term memory by using a set of cognitive decision tasks. Male and female subjects were administered either 0.0 or 1.0 milliliter of ethanol per kilogram of body weight, and then asked to make physical, lexical, and semantic decisions about pairs of words. In general, intoxicated(More)
DDAVP has been shown to facilitate memory, especially retrieval, in humans. Healthy young male adult subjects received DDAVP (60 micrograms) in a cross-over design with a one-week interval between sessions. Results indicated that DDAVP improved immediate memory during the first but not the second testing session, particularly for low-verbal subjects.(More)
Alpers disease consists of diffuse cerebral degeneration manifested as developmental delay, seizures, vomiting, and progressive neuromuscular deterioration, with liver disease and death. We report the clinical course of the liver disease, histologic progression of the hepatic lesions, and etiologic investigations in five patients (four girls, three(More)
PURPOSE To describe the clinical outcomes in adults with favorable histologic type (FH) Wilms tumor (WT) registered in the National Wilms Tumor Studies (NWTS) 4-5. We also describe the results of patients treated in the "modern era" (1979-2001) with surgical staging, central pathology review and stage-appropriate multimodality treatment. METHODS AND(More)
