Rare. Transient neonatal myasthenia gravis, i.e., TNMG (also termed neonatal myasthenia gravis [1] ), and its more severe form, fetal acetylcholine receptor inactivation syndrome (i.e., FARIS), is one of the various types of myasthenia gravis (i.e., MG). [2] MG is an autoimmune disease in which individuals form antibodies that circulate in ...
It most commonly affects women under 40 and people from 50 to 70 years old of either sex, but it has been known to occur at any age. Younger people rarely have thymoma. Prevalence in the United States is estimated at between 0.5 and 20.4 cases per 100,000, with an estimated 60,000 Americans affected.
Esotropia is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [ 1] It is the opposite of exotropia and usually involves more severe axis deviation than esophoria. Esotropia is sometimes erroneously called ...
Neonatal conjunctivitis is a form of conjunctivitis (inflammation of the outer eye) which affects newborn babies following birth. It is typically due to neonatal bacterial infection, although it can also be non-infectious (e.g. chemical exposure). [ 1] Infectious neonatal conjunctivitis is typically contracted during vaginal delivery from ...
Some degree of weight gain is expected during pregnancy. The enlarging uterus, growing fetus, placenta, amniotic fluid, normal increase in body fat, and increase in water retention all contribute weight gain during pregnancy. The amount of weight gain can vary from 5 pounds (2.3 kg) to over 100 pounds (45 kg).
Pediatrics. Transient tachypnea of the newborn is a respiratory problem that can be seen in the newborn shortly after delivery. It is caused by retained fetal lung fluid due to impaired clearance mechanisms. [ 1] It is the most common cause of respiratory distress in term neonates. [ 2][ 3] It consists of a period of tachypnea (rapid breathing ...
Brown syndrome is a rare form of strabismus characterized by limited elevation of the affected eye. The disorder may be congenital (existing at or before birth), or acquired. Brown syndrome is caused by a malfunction of the superior oblique muscle, causing the eye to have difficulty moving up, particularly during adduction (when eye turns ...
Unlike hemolytic disease of the fetus and newborn, NAIT occurs during the first pregnancy in up to 50% of cases, [1] and the affected fetuses may develop severe thrombocytopenia (<50,000 μL −1) very early during pregnancy (as early as 20 weeks gestation, consistent with the development of platelet antigens, [1] and the majority of the time ...
