Abstract: The therapeutic value of ketoconazole for long term treatment of patients with Cushing's syndrome was studied. Seven patients with Cushing's disease and one with an adrenal adenoma received 600-800 mg/day ketoconazole for 3-13 months. Plasma ACTH, cortisol, and dehydroepiandrosterone sulfate levels and urinary cortisol, 17-ketosteroid, and tetrahydro-11-deoxycortisol excretion were determined periodically during the treatment period. Plasma ACTH and cortisol responses to CRH stimulation were determined before and during treatment. Rapid and subsequently persistent clinical improvement occurred in each patient; plasma dehydroepiandrosterone sulfate and urinary 17-ketosteroid and cortisol excretion decreased soon after the initiation of treatment, subsequently remaining normal or nearly so throughout the treatment period. Urinary tetrahydro-11-deoxycortisol excretion increased significantly. Plasma cortisol levels decreased. Plasma ACTH levels did not change, and individual plasma ACTH and cortisol increments in response to CRH were comparable before and during treatment. The cortisol response to insulin-induced hypoglycemia improved in one patient and was restored to normal in another. The seven patients tested recovered normal adrenal suppressibility in response to a low dose of dexamethasone during ketoconazole treatment. Ketoconazole is effective for long term control of hypercortisolism of either pituitary or adrenal origin. Its effect appears to be mediated by inhibition of adrenal 11 beta-hydroxylase and 17,20-lyase, and it, in some unknown way, prevents the expected rise in ACTH secretion in patients with Cushing's disease.

Abstract: We have characterized binding and several actions of the somatomedins [insulin-like growth factors I and II (IGF-I and IGF-II)] on L6 myoblasts. Both IGF-I and IGF-II are potent stimulators of amino acid uptake, cell proliferation, and differentiation; they also suppress protein degradation in these cells. In all measurements, the relative potencies are IGF-I greater than IGF-II greater than insulin. Two recombinant DNA-produced analogs of IGF-I, (Thr59)IGF-I and (N-Met)IGF-I, were as active as native IGF-I in all four assays. However, when 125I-labeled hormones were used for studies of binding to IGF receptors, there was a striking difference between the native and recombinant IGF-I molecules. Both were bound significantly by the type I receptor (a 350K molecule that is dissociated upon sulfhydryl reduction), but the recombinant analogs exhibited little cross-reactivity with the type II receptor (a 220K molecule that is not dissociated by reduction). Thus, the equal activity of native IGF-I and its recombinant DNA-produced analogs coupled with the higher potency of IGF-I (compared to IGF-II) suggest that the type II receptor plays little or no role in the four actions of the somatomedins studied in L6 myoblasts.
Which is the apt title for the abstract? option1: The type II insulin-like growth factor (IGF) receptor has low affinity for IGF-I analogs: pleiotypic actions of IGFs on myoblasts are apparently mediated by the type I receptor. option2: Craniotomy flap osteomyelitis: a diagnostic approach.

Ex Output:
The type II insulin-like growth factor (IGF) receptor has low affinity for IGF-I analogs: pleiotypic actions of IGFs on myoblasts are apparently mediated by the type I receptor.

Abstract: This study describes a cohort of foreign medical school graduates (FMGs) who first sat for the American Board of Internal Medicine's (ABIM) 1982 certifying examination, compares their performance with that of US medical school graduates, describes differences between US citizen FMGs and alien FMGs, and examines which background factors predict success on the ABIM examination. Data for this study were derived by combining information retained by the Educational Commission for Foreign Medical Graduates with ABIM data. Most FMGs who took the 1982 ABIM certifying examination for the first time were educated in and citizens of Asia, but a sizable minority were US citizens educated in Europe. Scores and program directors' ratings were lower for FMGs than US medical school graduates, and they attended different types of training programs. United States citizen FMGs were very similar to alien FMGs. Foreign medical school graduates who did well on the ABIM examination had done well on the Educational Commission for Foreign Medical Graduates examination and were rated highly by their residency program director.
