Pituitary apoplexy after thyrotropin-releasing hormone stimulation test in a patient with pituitary macroadenoma.
Pituitary apoplexy is a rare complication of pituitary tumors. We report a case of a 41-year-old female with acromegaly due to a pituitary macroadenoma, who developed pituitary apoplexy after a thyrotropin-releasing hormone (TRH) 200 microgram intravenous injection stimulation test. Neither emergency computed tomography (CT) scans nor magnetic resonance imaging (MRI), performed 6 hours and 12 h...
متن کاملDominant role of thyrotropin-releasing hormone in the hypothalamic-pituitary-thyroid axis.
Hypothalamic thyrotropin-releasing hormone (TRH) stimulates thyroid-stimulating hormone (TSH) secretion from the anterior pituitary. TSH then initiates thyroid hormone (TH) synthesis and release from the thyroid gland. Although opposing TRH and TH inputs regulate the hypothalamic-pituitary-thyroid axis, TH negative feedback is thought to be the primary regulator. This hypothesis, however, has y...
متن کاملUsefulness of the thyrotropin-releasing hormone test in pre-clinical acromegaly.
Acromegaly is caused primarily by pituitary growth hormone (GH)-secreting tumors. It is usually recognized because of characteristic manifestations, and diagnosed clinically. However, there exists a mild stage of acromegaly, which poses a diagnostic problem due to the absence of typical clinical manifestations. Here we present four patients with pre-clinical acromegaly, who showed minimal acrom...
متن کاملThe Therapeutic Effect of Thyrotropin Releasing Hormone in Amyotrophic Sclerosis
Although the issue has not yet been fully resolved, there is reason to believe that TRI-I may have a trophic effect on the normal motoneuron and may transien tly improve the neurologic deficit in ALS. Since ALS is not a simple TRI-I deficiency disease, this improvement probably occurs via a secondary mecha -nism-possibly another neurotransmitter. It is uncertain at this time whether this effec...
متن کاملStimulation of the hypothalamic-pituitary-adrenal axis with corticotropin releasing hormone in patients with psoriasis.
OBJECTIVE Psychocutaneous diseases constitute a large proportion of psychosomatic disorders, with psoriasis being one of the most typical cases. Though alteration of Hypothalamic-Pituitary-Adrenal (HPA) axis function has been suggested as underlying several psychiatric disorders and psychosomatic diseases, there is little evidence of reduced response of the HPA axis in psoriasis after psychosoc...
