Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta- human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG. [ 1][ 2] On ultrasound and MRI, theca lutein ...
Perinatal stroke. Perinatal stroke is a disease where an infant has a stroke between the 140th day of the gestation period and the 28th postpartum day, [ 1] affecting up to 1 in 2300 live births. [ 2] This disease is further divided into three subgroups, namely neonatal arterial ischemic stroke, neonatal cerebral sinovenous ischemic stroke, and ...
Spinal cord stroke. Spinal cord stroke is a rare type of stroke with compromised blood flow to any region of spinal cord owing to occlusion or bleeding, leading to irreversible neuronal death. [ 1] It can be classified into two types, ischaemia and haemorrhage, in which the former accounts for 86% of all cases, a pattern similar to cerebral ...
Subclinical hyperthyroidism in pregnancy is associated with an increased risk of pre-eclampsia, low birth weight, miscarriage and preterm birth. [50] Propylthiouracil is the preferred treatment of hyperthyroidism (both overt and subclinical) in the first trimester of pregnancy as it is associated with less birth defects than methimazole. [50]
Euthyroid sick syndrome ( ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [ 1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional. This condition may result from allostatic responses of hypothalamus-pituitary-thyroid feedback control, dyshomeostatic disorders ...
Congenital iodine deficiency syndrome ( CIDS) is a medical condition present at birth marked by impaired physical and mental development, due to insufficient thyroid hormone ( hypothyroidism) often caused by insufficient dietary iodine during pregnancy. It is one cause of underactive thyroid function at birth, called congenital hypothyroidism ...
Treatment is determined based on the primary cause of anterior spinal cord syndrome. When the diagnosis of anterior spinal cord syndrome is determined, the prognosis is unfortunate. The mortality rate is approximately 20%, with 50% of individuals living with anterior spinal cord syndrome having very little or no changes in symptoms. [1]
The thyroid system of the thyroid hormones T 3 and T 4 [1] Thyroid hormones are any hormones produced and released by the thyroid gland, namely triiodothyronine (T 3) and thyroxine (T 4). They are tyrosine-based hormones that are primarily responsible for regulation of metabolism. T 3 and T 4 are partially composed of iodine, derived from food. [2]
