Under general anaesthesia between 105 and 110 days of gestation (days; term ~145 days), one twin fetus was thyroidectomised (TX), while the other was sha...

Development of the fetal hypothalamic-pituitary-adrenal (HPA) axis is important for normal maturation of the fetus and the timing of parturition. In hypothyroid fetuses, gestational length may be prolonged and maturational processes delayed, although the role of the HPA axis is unknown. This study investigated the effects of hypothyroidism before birth on the structure and function of the anterior pituitary and adrenal glands in fetal sheep near term.All...

The most common cause of hyperprolactinemia is a prolactinoma in women after pregnancy is excluded. A 34-year-old female presented to our clinic with a 1.5 year history of secondary amenorrhea, galactorrhea and malaise. Prolactin (PRL) level was found to be 151.89 ng/ml. Pituitary imaging was reported to be normal. An examination of the patient revealed that PRL level was still high so the dose of cabergoline was further increased and subsequently, bromocriptine was added to t...
