This report describes gelastic seizures in patients with optic nerve hypoplasia and hypothalamic dysfunction without hypothalamic hamartoma. All participants (n = 4) from the optic nerve hypoplasia registry study at Children's Hospital Los Angeles presenting with gelastic seizures were included. The
A newborn male with mitochondrial complex I deficiency suffered from neonatal epileptic seizures, which later developed into infantile spasms. The infant was blind due to aplasia of the retinal vessels and hypoplasia of the optic nerve. There was congenital lactic acidosis, which persisted in later
Five children had bilateral optic nerve hypoplasia, absent septum pellucidum, and hypopituitarism. Absence of the septum pellucidum was shown by computed axial tomography. All of the children were first-born. One of the children was definitely not mentally retarded and one at age 7 months was
OBJECTIVE
It is essential to identify hypopituitarism in children with optic nerve hypoplasia (ONH) because they are at risk for developmental delay, seizures, or death. The purpose of this study is to determine the reliability of neurohypophyseal abnormalities on magnetic resonance imaging (MRI)
OBJECTIVE
Optic nerve hypoplasia (ONH) is a heterogeneous disease with variable findings of pituitary insufficiency, CNS and neurodevelopmental abnormalities. We characterized the spectrum of endocrinopathy in a cohort of children with ONH and attempted to correlate the presence of different midline
BACKGROUND
A porencephalic cyst is a cavity within the cerebral hemisphere, filled with cerebrospinal fluid, that communicates directly with the ventricular system. It is a rare condition probably caused by vascular occlusion resulting from an insult during fetal development or an injury occurring
Arachnoid cysts are congenital benign intracranial collections of cerebrospinal fluid. Most arachnoid cysts are small and asymptomatic. They are usually located in the temporal fossa. Classically described complications result from compression of adjacent structures and include neurologic
Congenital clubfoot is a heterogeneous disorder that can result in functional disability, deformity, and pain if left untreated. Although the etiology is considered multifactorial in the majority of cases, a 17q23.1–q23.2 duplication has been reported in families with congenital clubfoot
BACKGROUND
Unbalanced chromosomal translocations may present with a variety of clinical and laboratory findings and provide insight into the functions of genes on the involved chromosomal segments.
METHODS
A 9 year-old boy presented to our clinic with Factor VII deficiency, microcephaly, a seizure
OBJECTIVE
To report the occurrence of nystagmus in children exposed to opiates and/or benzodiazepines during pregnancy, and to describe the associated ocular and systemic findings.
METHODS
Clinical examination and casenote review of 14 children with nystagmus whose mothers had misused opiates and/or
A wide cavum septum pellucidum defined as a separation of greater than 1 cm of the leaves occurs uncommonly. Nine children with wide cavum septum pellucidum were studied; 8 were abnormal. Observed abnormalities included cognitive impairment (8), seizures (4), hypoplasia of the corpus callosum (4),
Mutations in the BRCA1-associated protein required for the ataxia telangiectasia mutated (ATM) activation-1 (BRAT1) gene cause lethal neonatal rigidity and multifocal seizure syndrome characterized by rigidity and intractable seizures and a milder phenotype with intellectual disability, seizures,
Bosch-Boonstra-Schaaf Optic Atrophy Syndrome (BBSOAS) is an autosomal dominant neurodevelopmental disorder caused by loss-of-function variants in NR2F1 and characterized by visual impairment, developmental delay, and intellectual disability. Here we report 18 new cases, provide additional clinical
Squalene synthase deficiency (SQSD) is a rare inborn error of cholesterol biosynthesis with multisystem clinical manifestations similar to Smith-Lemli-Optiz syndrome. Key clinical features include facial dysmorphism, a generalized seizure disorder presenting in the neonatal period, Septo-optic dysplasia (SOD)/de Morsier's syndrome is characterized by optic nerve hypoplasia, pituitary endocrine dysfunction, and midline brain abnormalities. Hypopituitarism, hypothyroidism, hypogonadism, and adrenal insufficiency can lead to severe hypoglycemia, adrenal crisis, seizures, and
