Patients with craniopharyngioma (CP) are more often operated by transcranial route than patients with nonfunctioning pituitary adenoma (NFPA), have higher prevalence of pituitary deficiencies, are more obese and dyslipidemic and have a higher mortality rate. A previous study in a large group of GHD subjects, showed that the effects of 2-year rhGH replacement are similar in patients operated for CP and in patients operated for NFPA, except for less reduction in fat mass in CP p...

A highly polymorphic microsatellite in the IGF1 gene promoter, composed of variable cytosine-adenine (CA) repeats (n=10–24) has been linked to IGF1 serum concentrations in normal, acromegalic and GHD subjects with conflicting results. Aim of this study was to investigate whether this polymorphism may influence the clinical and biochemical characteristics of adult patients with GHD (n=97). Moreover, the response to 12-month rhGH replacement in terms of IGF1 l...

Background: GH deficiency (GHD) may occur in about 60% of acromegalics treated and cured by surgery or radiotherapy. Effects of GH replacement have not yet been extensively studied in such a patients.Aim: To investigate whether rhGH replacement improve metabolic parameters in acromegalic patients who become GHD.Patients and methods: Forty GHD patients (mean age (S.D.): 48±10, BMI 27±3 kg/m2) were...

Introduction: Double aneuploidy involving both sex and autosomal chromosomes (chr) is very rare, Down–Turner syndrome being the most frequent. Fourty-seven cases of Down–Turner mosaicism have been reported, only nine with a karyotype containing Y chr (phenotype: seven male, two ambiguous genitals).Case report: We describe a girl affected with Down-Turner syndrome. The cytogenetic analysis on peripheral lymphocytes, performed 2 months after birt...

Thyrotropin-secreting pituitary adenomas (TSH-omas) account for less than 1% of all pituitary adenomas. Here we report retrospective data of 17 patients (seven M and 10 F) with TSH-oma followed at our centre from 1990 to present. Median follow-up time was 9.7 years. The mean age at diagnosis was 43±12 years. Radiological evaluation revealed macroadenomas in 11 of 17 patients (71.6%). Macroadenomas were extrasellar in 58.4% of cases, while only one microadenoma had extrase...
