OBJECTIVE A consensus exists that severe growth hormone deficiency (GHD) in adults is defined by a peak GH response to insulin-induced hypoglycemia (insulin tolerance test, ITT) of less than 3 microg/l based on a cohort of subjects with a mean age of 45 years. DESIGN AND METHODS By considering one of the following two criteria for the diagnosis of(More)
OBJECTIVES Hepcidin, a peptide hormone released by hepatocytes into circulation is the main regulator of dietary iron absorption and cellular iron release. Although commercial tests are available, assay harmonization for hepcidin has not been yet reached, making reference intervals and consequent clinical decisions still elusive for each assay and specific(More)
OBJECTIVE To define the appropriate diagnostic cut-off limits for the GH response to GHRH+arginine (ARG) test and IGF-I levels, using receiver operating characteristics (ROC) curve analysis, in late adolescents and young adults. DESIGN AND METHODS We studied 152 patients with childhood-onset organic hypothalamic-pituitary disease (85 males, age(More)
CONTEXT The 2007 Consensus Statement suggested a peak GH cutoff to insulin tolerance test (ITT) of less than 6 microg/liter in the diagnosis of permanent GH deficiency (GHD) in young adults with childhood-onset GHD (COGHD), although further validation was recommended. OBJECTIVE The aim of the study was to evaluate the accuracy of ITT, mean 12-h(More)
BACKGROUND The optimal therapeutic approach for patients with Hodgkin's disease (HD) and human immunodeficiency virus (HIV) infection is unknown. In an attempt to improve the results obtained with standard chemotherapy and to decrease the occurrence of opportunistic infections (OI) during chemotherapy and follow-up observed in a previous experience, the(More)
Fusarium is an ubiquitous fungus commonly found in soil and on plants. Human infection usually occurs as a result of inoculation of the organism through the body surface, thus causing skin infection, onychomycosis, keratitis, endophthalmitis and arthritis. Dissemination may occur in subjects with underlying immunodeficiency. Among immunocompromised hosts,(More)
Chromosome banding pattern of bone marrow cells, cell morphology according to the FAB classification, and clinical finding were compared in two groups of adult patients with acute nonlymphocytic leukemia (ANLL): 52 patients occupationally exposed to chemical solvents, insecticides, or petrol products, and 110 patients with no history of occupational(More)
Clinical or biochemical findings were reevaluated in 34 pediatric patients with primary renal tubular hypokalemic metabolic alkalosis. The patients were subdivided into two groups. Bartter syndrome (primary renal tubular hypokalemic metabolic alkalosis with normocalciuria or hypercalciuria) was diagnosed in 18 patients with molar urinary calcium/creatinine(More)
