Introduction: Thyrotropin-producing adenomas (TSH-omas) constitute about 1% of pituitary adenomas. TSH-omas are a rare cause of hyperthyroidism. In conjunction with biochemical parameters and dynamic endocrine testing, image evaluation of the pituitary gland and sella turcica is mandatory for establishing a correct diagnosis. TSH-omas are usually large tumors and tend to be invasive. Greater amounts of invasion correlate with incomplete surgical removal of the tumor and, thus,...

Morbid obesity (MO) is often complicated by obstructive sleep apnoea (OSA), which in some cases is evaluated by pulsioximetry. This cross-sectional study was designed to investigate the prevalence of discordance between desaturation index (DI) and apnoea–hypopnoea index (AHI) and its effects on insulin resistance and secretion in MO patients candidate to bariatric surgery (n=496) in whom a full polysomnographic study was carried out. We identified 163 (33%) out o...
