Cough Coryza Conjunctivitis Concurrent fever and rash Coplik (koplik spot Cephalocaudal spreading rash Cervical lymphadenopathy Measles • Measles is caused by the paramyxovirus, and is highly contagious. • The incubation period is on average 10 days (7-18 days), and patients are usually considered infectious for several days before and after the onset of the rash when the viral load is highest. • • • • • There is a prodromal illness which consists of the 3 C's (cough, coryza and conjunctivitis). Koplik spots (seen in the buccal mucosa) are pathognomonic for measles and are usually seen several days after onset of the ilness. Described as being like "grains of sand" • • • Rash starts 3-4 days after onset of symptoms. Starts behind the ears and forehead, spreading over the whole body from head to foot. The rash is dark red macules and papules which become confluent and blotchy. Rash usually lasts for 5-10 days and classically desquamates as it resolves. Patients should be isolated for at least 5 days after appearance of rash. Any contacts if not immune should be vaccinated within 72 hours. Anti-measles IgM is generally detectable 3 days after onset of rash. Anti-measles IgG has a delayed onset before becoming positive - usually peaks at 14 days after onset of rash. Other diagnostic tests include NPA for measles IF and first pass urine for measles PCR.

Prune Belly Syndrome: -AKA Eagle-Barrett Syndrome -Three main problems: Poor development of the abdominal muscles,(cryptorchidism) and urinary tract problems -The causes of prune belly syndrome are unknown -The condition affects mostly boys (95%). -The amniotic fluid volume may be normal or decreased in neonates with prune belly syndrome. -The presence of oligohydramnios may account for some of the accompanying findings of the extremities -Poor abdominal wall muscles : poor coughing and constipation -Mortality rate 20% -Patients with prune belly syndrome also have an increased incidence of TOF and ventriculoseptal defects. Congenital Cataracts: -Definition: Opacification of the lens. Congenital cataracts usually are diagnosed at birth. -Patients require a full metabolic, infectious, systemic, and genetic workup. -Common causes are hypoglycemia, trisomy (eg, Down, Edward, and Patau syndromes), myotonic dystrophy, TORCH, and prematurity. -Workup: For unilateral cataracts: TORCH titers and Venereal Disease Research Laboratory (VDRL) test. -For bilateral cataracts: CBC, BUN, TORCH titers, VDRL, urine for reducing substances, red cell galactokinase, urine for amino acids, calcium, and phosphorus. -Additional Tests: CT scan of brain.
