Active acromegaly is associated with significant comorbidity and reduced quality of life. Cross-sectional studies have shown that quality of life did not significantly change in long-term cured acromegalic patients. However, the effect of medical treatment on the quality of life in the short term is unknown.We evaluated the quality of life by a disease-specific questionnaire in a longitudinal study before and after a 6-month course with somatostatin anal...

Hypogonadism is still a poorly-defined clinical entity. Recently approved and published guidelines to diagnosis and treatment of hypogonadism claim the necessity of accompanying biochemical thresholds with clinical symptoms and monitoring under treatment a specific aspect of the ‘wide spectrum’ hypogonadism (libido, erection, bone mass, muscle strength and so on). This is due both to different levels of thresholds for different tissues and to individual variability.<...

Exon 1 of the androgen receptor (AR) gene contains a variable number of CAG triplets, (CAGr)n which encode a polyglutamine stretch of variable length in the N-terminal domain of the receptor. Experimental evidence has accumulated in demonstrating that the length of this stretch influences the transcriptional activity induced by the AR and therefore modulates target organs responsiveness to androgens.The (CAGr)n is inversely associated with the transcript...

Thyroid hormone resistance (THR) and pituitary TSH-secreting adenomas (TSHoma) are both characterised by increased serum free thyroid hormone levels and normal TSH concentrations. Differentiation of the two syndromes is a clinical challenge, and relies on the suppression (TRH) or lack of suppression (TSHoma) of TSH-dependent parameters and on the presence of germinal mutations in the thyroid hormone receptor beta 1 gene in patients with THR. Thyroid blood flow, evaluated using...
