“…Congenital varicella syndrome is characterized by a number of clinical manifestations: premature labor and small for gestational age; cutaneous lesions (e.g., scars in a dermatomal distribution and aplasia cutis congenita); CNS and peripheral nervous system abnormalities (e.g., microcephaly, hydrocephalus, cortical/cerebellar atrophy, mental retardation, facial nerve palsy, phrenic nerve palsy, recurrent laryngeal nerve palsy, bulbar palsy, brachial plexus palsy, and intracranial calcifications); ocular abnormalities (e.g., cataracts, nystagmus, microphthalmia, chorioretinitis, and optic atrophy); autonomic nervous system dysfunction (e.g., Horner syndrome, neurogenic bladder, dysphagia, and anal sphincter dysfunction); neuromuscular/orthopedic abnormalities (e.g., talipes equinovarus or calcaneovalgus deformity, hypoplasia/atrophy of the limb, rudimentary digit, hypoplasia of ribs, and scoliosis); gastrointestinal anomalies (e.g., duodenal stenosis, jejunoileal atresia, Meckel diverticulum, colonic atresia, colonic stricture, small left colon syndrome, and sigmoid atresia); and genitourinary anomalies (e.g., hydronephrosis, hydroureter, renal dysplasia, renal agenesis, and undescended testes) [6][7][8][9][10][11][12][13][14][15][16][17][18].…”
