CONTEXT Outcomes of congenital adrenal hyperplasia due to classic 21-hydroxylase deficiency (21OHD) have been widely studied in children and women, but less so in men. OBJECTIVE The objective was to analyze data from a network of metropolitan French teaching hospitals on the clinical outcome of classic 21OHD in a large sample of congenital adrenal(More)
This study was conducted to identify the most rate-limiting amino acids for whole-body protein synthesis in acquired immunodeficiency syndrome (AIDS) patients. We postulated that an essential amino acid that would be rate limiting in AIDS should have a low basal plasma concentration and should remain at a low level during amino acid infusion. Seven male(More)
Free radicals are likely involved in the aging process and there is a growing body of evidence that free radical damage to cellular function is associated with a number of age-related diseases such as atherosclerosis, cancer, and neurologic disorders. The present study was designed to evaluate in a healthy population the evolution with age of 8-epiPGF2alpha(More)
We have examined insulin action on glucose metabolism in six hypothyroid patients before and after regular thyroid hormone treatment, and in six healthy volunteers before and after transient induction of moderate hyperthyroidism. Insulin was infused under euglycaemic and eukalaemic clamps. An appropriate amino acid infusion was used to blunt insulin-induced(More)
CONTEXT ACTH-independent macronodular adrenal hyperplasia (AIMAH) is a rare and heterogeneous condition characterized by abnormal steroid production. Cortisol secretion can be regulated by aberrant hormone receptors. OBJECTIVE A large series of patients with AIMAH were evaluated to provide information on the prevalence and profile of aberrant regulations,(More)
The experiment was carried out to clarify the roles of insulin and amino acids on protein synthesis in fed lactating goats (30 days postpartum). Protein synthesis in the liver and various skeletal muscles was assessed after an intravenous injection of a large dose of unlabeled valine containing a tracer dose of L-[2,3,4-3H]valine. The animals were divided(More)
49,XXXXY pentasomy or Fraccaro's syndrome is the most severe variant of Klinefelter's syndrome (KS) affecting about 1/85000 male births. The classical presentation is the triad: mental retardation, hypergonadotropic hypogonadism and radio ulnar synostosis. Indeed, the reproductive function of Fraccaro's syndrome is distinguished from KS. Besides, Leydig(More)
Staphylococcus aureus is the main cause of diabetic foot osteomyelitis (DFO) and can be treated medically or by surgery. We investigated the outcome of consecutive patients with a diagnosis of S aureus DFO retrospectively in 4 hospitals according to the type of management, medical (including debridement at bedside) or surgical. The outcome was classified as(More)
Temozolomide (TMZ) has been proposed as a therapeutic option in aggressive pituitary tumors. Among the published cases, GH expressing tumors were rare. We describe a patient with initially benign silent GH adenoma that transformed into an aggressive GH secreting tumor resistant to usual therapy. MGMT expression was high and the MGMT promoter was(More)
