Adenomas exceeding 10 mm (0.39 in) in size are defined as macroadenomas, while those smaller than 10 mm (0.39 in) are referred to as microadenomas. Most pituitary adenomas are microadenomas and have an estimated prevalence of 16.7% (14.4% in autopsy studies and 22.5% in radiologic studies).
Since pharmacological therapy has had little effect on these tumors, a trans-sphenoidal surgery to remove part of the pituitary gland is the first treatment option. [5] TSH-secreting: Another rare condition only resulting in 1% of pituitary surgeries is a result of the increase in the secretion of the thyroid-stimulating hormone.
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.
Medical therapy is the preferred treatment in prolactinomas. [3] In most cases, medications that are dopamine agonists, such as cabergoline, [52] quinagolide and bromocriptine (often preferred when pregnancy is possible), are the treatment of choice used to decrease prolactin levels and tumor size upon the presence of microadenomas or ...
The authors felt neither pituitary nor adrenal insufficiency was involved, but that direct neural control of renal proximal tubular reabsorption of sodium was disrupted. [25] In 1953, Leaf et al, demonstrated that exogenous administration of the antidiuretic hormone vasopressin resulted in hyponatremia and a natriuresis dependent on water ...
Cancer pain treatment aims to relieve pain with minimal adverse treatment effects, allowing the person a good quality of life and level of function and a relatively painless death. [27] Though 80–90 percent of cancer pain can be eliminated or well controlled, nearly half of all people with cancer pain in the developed world and more than 80 ...
Interventional pain management or interventional pain medicine is a medical subspecialty defined by the National Uniforms Claims Committee (NUCC) as, " invasive interventions such as the discipline of medicine devoted to the diagnosis and treatment of pain related disorders principally with the application of interventional techniques in managing sub acute, chronic, persistent, and intractable ...
The pituitary gland or hypophysis is an endocrine gland in vertebrates. In humans, the pituitary gland is located at the base of the brain, protruding off the bottom of the hypothalamus. The human pituitary gland is oval shaped, about 1 cm in diameter, 0.5–1 gram (0.018–0.035 oz) in weight on average, and about the size of a kidney bean. [2 ...
