About 35% of the cases are caused by a single aldosterone-secreting adenoma, a condition known as Conn's syndrome. [ 7 ] [ 8 ] Many patients experience fatigue, potassium deficiency and high blood pressure which may cause poor vision, confusion or headaches .
Multiple endocrine neoplasia type 2 (also known as "Pheochromocytoma (codons 630 and 634) and amyloid producing medullary thyroid carcinoma", [1] "PTC syndrome," [1] and "Sipple syndrome" [1]) is a group of medical disorders associated with tumors of the endocrine system. The tumors may be benign or malignant .
Pheochromocytoma is a neoplasm composed of cells similar to the chromaffin cells of the mature adrenal medulla. Pheochromocytomas occur in patients of all ages, and may be sporadic, or associated with a hereditary cancer syndrome, such as multiple endocrine neoplasia (MEN) types IIA and IIB, neurofibromatosis type I, or von Hippel–Lindau ...
Functional adrenocortical adenomas demonstrate symptoms consistent with mixed endocrine syndromes. In most reported cases of adrenocortical adenoma, patients have presented with one or multiple endocrine syndromes such as hyperaldosteronism / Conn's Syndrome , [ 3 ] hypercortisolism / Cushing's syndrome , [ 4 ] hyperandrogenism / feminization ...
If a patient has the characteristic signs and symptoms of a pheochromocytoma and the decision is made to pursue additional biochemical (blood work) evaluation, the differential diagnosis is important as it is more likely to be something other than a pheochromocytoma given the relative frequency of 0.8 per 100,000 person-years.

In 1954 Wermer noted that this syndrome was transmitted as a dominant trait. [citation needed] In 1959 Hazard et al. described medullary (solid) thyroid carcinoma. [citation needed] In 1961 Sipple described a combination of a pheochromocytoma, medullary thyroid carcinoma and parathyroid adenoma. [citation needed]
After extensive research he had found a condition he called primary hyperaldosteronism, later called Conn syndrome. There were elevated levels of aldosterone in her circulation, coming from a hormone producing adrenal adenoma. Conn wrote a total of 284 articles and book chapters and was recognized as a tutor stimulating others in research.
Over time, affected children experience mental impairment, worsening seizures and progressive loss of sight, speech and motor skills. Batten disease is a terminal disease; life expectancy varies depending on the type or variation. [7] [8] Females with juvenile Batten disease show first symptoms a year later than males, but on average die a year ...
