Hyperpituitarism is a condition due to the primary hypersecretion of pituitary hormones; [3] [medical citation needed] it typically results from a pituitary adenoma.In children with hyperpituitarism, disruption of growth regulation is rare, either because of hormone hypersecretion or because of manifestations caused by local compression of the adenoma.
However, more rapid development of the disorder is the rule when it occurs during, or shortly after, pregnancy (even after miscarriage or abortion). Indeed, autoimmune hypophysitis occurs more commonly during and shortly after pregnancy than at any other time. [6]
Treatment is by the timely correction of hormone deficiencies. In many cases, surgical decompression is required. Many people who have had a pituitary apoplexy develop pituitary hormone deficiencies and require long-term hormone supplementation. The first case of the disease was recorded in 1898. [1]
Hormone secreting pituitary adenomas cause one of several forms of hyperpituitarism.The specifics depend on the type of hormone. Some tumors secrete more than one hormone, the most common combination [8] being GH and prolactin, which present as Gigantism or Acromegaly and unexpected lactation (in both men and women).
Sheehan's syndrome, also known as postpartum pituitary gland necrosis, occurs when the pituitary gland is damaged due to significant blood loss and hypovolemic shock (ischemic necrosis) or stroke, originally described during or after childbirth leading to decreased functioning of the pituitary gland (hypopituitarism). [1]
Treatment involves drinking sufficient fluids to prevent dehydration. [1] Other treatments depend on the type. [1] In central and gestational DI, treatment is with desmopressin. [1] Nephrogenic DI may be treated by addressing the underlying cause or by the use of a thiazide, aspirin or ibuprofen. [1]
Post-maturity is more likely to happen when a mother has had a post-term pregnancy before. After one post-term pregnancy, the risk of a second post-term birth increases by 2 to 3 times. [8] Other, minor risk factors include an older or obese mother, a white mother, male baby, or a family history of post-maturity. [9]
There are many causes of AHH, mostly due to structural lesions or functional abnormalities involving the HPG axis such as sarcoidosis, lymphocytic hypophysitis, pituitary adenomas, craniopharyngiomas and other CNS tumours. Most of these patients have multiple pituitary hormone deficiencies. [12] Hyperprolactinaemia is the
