Five cases of a new disease presented with muscular weakness or cramping after exercise; three of the cases also had an elevated serum creatine phosphokinase. Muscle biopsies were histologically normal but lacked adenylate deaminase by stain and solution assay, while the erythrocyte isozyme was normal. A clinical diagnostic test has been developed, and the(More)
All patients with oligodendrogliomas (554) from the repository of the Armed Forces Institute of Pathology were retrospectively analyzed. The pathological diagnosis was confirmed in 323 patients and each case was graded according to a previously established grading system. The clinical features of these 323 verified cases of oligodendroglioma are presented,(More)
A prospective controlled clinical-neurophysiological-pathological study of 71 patients with oat cell carcinoma of the lung revealed no increased incidence of peripheral neuropathy at the initial stages of illness. All patients developed neuropathy by the time they had lost 15% of their body weight, but the neuropathy was less severe than in 20 age-matched(More)
63 patients with alcoholic-nutritional peripheral neuropathy were given neurologic, electrophysiologic and nutritional examinations. 24 of these patients were reexamined later in the course of their disease, after from 2 to 72 months (mean 33). Alcoholic-nutritional neuropathy appeared and worsened after bouts of heavy alcohol intake and malnutrition.(More)
Myoadenylate deaminase deficiency is believed to reflect a genetic deficiency of skeletal muscle, but its pattern of inheritance has not been established. We examined, histochemically and by quantitative biochemical assay, muscle biopsy specimens from 3 putative carriers of this disorder. Adenylate kinase and creatine kinase were assayed in parallel with(More)
We conducted a population-based case-control study with 338 patients, less than 15 years of age, diagnosed with a primary tumor of the central nervous system from January 1968 through December 1977 in 53 New York State counties. The study also included 676 controls selected from the birth certificate files of the New York State Department of Health. We(More)
Hartnup disease is a rare genetic disorder of amino acid transport associated with variable and intermittent clinical abnormalities. A family is described in which three siblings had an intermittently progressive neurological disease and two of the affected siblings had the Hartnup-pattern aminoaciduria. Neuropathological examination of one case showed(More)
