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]
The signs and symptoms of hypopituitarism vary, depending on which hormones are undersecreted and on the underlying cause of the abnormality. The diagnosis of hypopituitarism is made by blood tests, but often specific scans and other investigations are needed to find the underlying cause, such as tumors of the pituitary, and the ideal treatment ...
Affected individuals may present with hypoglycaemia during the neonatal period, or with growth retardation during childhood (those diagnosed in the neonatal period appear to be affected by a particularly severe form of the disorder). PSIS is a common cause of congenital hypopituitarism, and causes a permanent growth hormone deficit.
CHH can be diagnosed in the male neonate with cryptorchidism (maldescended testes) and a micropenis as signs of GnRH deficiency. [4] There are no clear signs of CHH in female neonates. [ 4 ] Another clinical sign of CHH, more specifically Kallmann syndrome, is a lack of a sense of smell due to the altered migration of GnRH neurons on the ...
However, clinical, laboratory data, and imaging can all help with the diagnosis.[8] First and foremost, patients present with symptoms of hypopituitarism and must undergo pituitary hormone function evaluation. [1] Biopsy is the only means of accurate diagnosis as no autoantigen has been discovered.
Congenital iodine deficiency syndrome (CIDS), also called cretinism, [2] is a medical condition present at birth marked by impaired physical and mental development, due to insufficient thyroid hormone production (hypothyroidism) often caused by insufficient dietary iodine during pregnancy.
Circumstances should provide clues fairly quickly for the new diseases causing severe hypoglycemia. All of the congenital metabolic defects, congenital forms of hyperinsulinism, and congenital hypopituitarism are likely to have already been diagnosed or are unlikely to start causing new hypoglycemia at this age.
The diagnosis is achieved with magnetic resonance imaging and blood tests. 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 ...
