 [kah-kek´se-ah]
a profound and marked state of constitutional disorder; general ill health and malnutrition. adj. adj cachec´tic.
cachexia hypophysiopri´va symptoms resulting from total loss of pituitary function, including loss of sexual function, bradycardia, hypothermia, apathy, and coma.
malarial cachexia the physical signs resulting from antecedent attacks of severe malaria, including anemia, sallow skin, yellow sclera, splenomegaly, hepatomegaly, and, in children, retardation of growth and puberty.

(shē'an),
hypopituitarism developing postpartum as a result of pituitary necrosis; caused by ischemia due to a hypotensive episode during delivery.

pituitary cachexia

Sheehan syndrome

A condition that follows postpartum uterine haemorrhage severe enough to cause circulatory collapse, resulting in pituitary necrosis and hypopituitarism, especially if disseminated intravascular coagulation (DIC) was also present.

Clinical findings
Galactorrhoea, amenorrhoea or oligomenorrhoea, secondary hypothyroidism, cold intolerance, hypotension, bradycardia, weight gain, hair loss, adrenal insufficiency, fatigue, loss of libido, hypoglycaemia, hyponatraemia.

Sim·monds dis·ease

(sim'ŏndz di-zēz')
Anterior pituitary insufficiency due to trauma, vascular lesions, or tumors; usually developing postpartum as a result of pituitary necrosis caused by ischemia during a hypotensive episode during delivery; characterized clinically by asthenia, loss of weight and body hair, arterial hypotension, and manifestations of thyroid, adrenal, and gonadal hypofunction.
Synonym(s): hypophysial cachexia, pituitary cachexia.

Simmonds,

Morris, German physician, 1855-1925.
Simmonds disease - anterior pituitary insufficiency due to trauma, vascular lesions, or tumors. Synonym(s): hypophysial cachexia; pituitary cachexia; Simmonds syndrome
Simmonds syndrome - Synonym(s): Simmonds disease

Sim·monds dis·ease

(sim'ŏndz di-zēz')
Anterior pituitary insufficiency due to trauma, vascular lesions, or tumors.
Synonym(s): hypophysial cachexia, pituitary cachexia.

cachexia

a profound and marked state of constitutional disorder; general ill health and malnutrition. See also emaciation.

cardiac cachexia
severe wasting that occurs in association with chronic cardiac insufficiency. The result of anorexia, malabsorption and poor tissue perfusion with cellular anoxia.
pituitary cachexia
that due to diminution or absence of pituitary function. Manifested by progressive loss of body weight associated with muscle atrophy due to lack of protein anabolism in the absence of growth hormone.

pituitary

1. a neuroepithelial endocrine gland of dual origin at the base of the brain in the sella turcica, attached by a stalk to the hypothalamus; called also hypophysis. It is composed of two main lobes, the anterior lobe (anterior pituitary, adenohypophysis), secreting several important hormones that regulate the proper functioning of the thyroids, gonads, adrenal cortex, and other endocrine glands, and the posterior lobe (posterior pituitary, neurohypophysis) whose cells serve as a reservoir for hormones having antidiuretic and oxytocic action, releasing them as needed, and in response to signals from the hypothalamus, itself responding to incoming signals from the nervous system received by the thalamus. Called also hypophysis. See also pituitrin, vasopressin, oxytocin, antidiuretic hormone, thyrotropin releasing hormone, adrenocorticotropic hormone, follicle-stimulating hormone, luteinizing hormone, melanocyte-stimulating hormone, prolactin and growth hormone.
2. pertaining to the pituitary gland.
3. a preparation of the pituitary glands of animals, used therapeutically.

pituitary abscess
abscess in the rete mirabile of the pituitary is recognizable clinically in cattle. The syndrome begins with a characteristic inability to close the mouth. Saliva drools, the tongue is prolapsed slightly, and there may be blindness, opisthotonos, loss of balance and recumbency.
pituitary-adrenal axis
the interactions between hypothalamus, pituitary and adrenal cortex, involving releasing factors, tropic hormones and negative feedback mechanisms.
pituitary alopecia
see growth hormone-responsive dermatosis.
pituitary cachexia
see pituitary cachexia.
pituitary dwarfism
congenital dwarfism with all parts properly proportioned. Affected animals are miniatures of normals. There is delayed bone development and epiphyseal fusion is retarded. It is inherited in cattle and German shepherd dogs. See also German shepherd dog dwarfism.
pituitary giantism
acromegaly.
fetal pituitary hormones
in sheep, cows and goats fetal pituitary ACTH stimulates fetal adrenal cortisol production inducing in turn placental estrogen secretion. Hence fetal placental hormone is important in the induction of parturition.
pituitary hypoplasia
congenital absence (aplasia) or incomplete growth (hypoplasia) of gland. Occurs in one form of inherited prolonged gestation in cattle and in poisoning by the weed Salsola tuberculata var. tomentosa. It is an inherited trait in German shepherd dogs.
posterior pituitary
1. the posterior lobe of the pituitary gland; the neurohypophysis.
2. a preparation of animal posterior pituitary having the pharmacological actions of its hormones, oxytocin and vasopressin; used mainly as an antidiuretic in the treatment of diabetes insipidus and as a vasoconstrictor.
pituitary rete mirabile abscess
see pituitary abscess.
pituitary tumor
includes adenoma, carcinoma and craniopharyngioma. All cause pressure on surrounding tissue and some cause endocrinological disturbances.
