1/38. Congenital varicella syndrome in the absence of cutaneous lesions.A case of congenital varicella syndrome characterized by intrauterine growth retardation, ocular and neurologic abnormalities, but no cutaneous lesions is reported. This case highlights the risk of embryopathy from varicella infection during pregnancy in non-immune women.- - - - - - - - - - ranking = 1keywords = neurologic (Clic here for more details about this article) |
2/38. poland-Moebius syndrome: a case report.BACKGROUND: The primary site of pathology in Moebius syndrome is still unknown, although several studies have variably localized the lesion in the extraocular muscles, cranial nerves, or central nervous system. CASE: A 24-year-old man with poland-Moebius syndrome and acquired progressive bilateral paralytic lower eyelid ectropion is described. OBSERVATIONS: In this patient, magnetic resonance imaging studies revealed a barely detectable pontine hypoplasia and normal recti muscles. Nerve conduction studies of the facial nerves showed a severe demyelinating or dysmyelinating type of neuropathy. Bilateral lower eyelid ectropium of the patient was successfully corrected by canthal tightening procedures. CONCLUSION: Contrary to many reported cases, this patient serves as a rare example of a progressive type of poland-Moebius syndrome presumably resulting from a combination of a brainstem abnormality and a peripheral neural degenerative process.- - - - - - - - - - ranking = 18.678280833034keywords = nervous system (Clic here for more details about this article) |
3/38. Ophthalmic manifestations of neonatal onset multisystem inflammatory disease.PURPOSE: To report the ophthalmic manifestations of neonatal onset multisystem inflammatory disease, a recently recognized, rare systemic disorder characterized by the triad of arthropathy, rash, and abnormal central nervous system development. METHOD: Case report. RESULTS: A 2-year-old female with neonatal onset multisystem inflammatory disease presented with visual acuity of fix and follow with each eye, bilateral optic nerve head pallor and gliosis, as well as marked sheathing of the peripapillary vessels. No vitreous inflammation or macular edema was found. visual acuity was stable from the neonatal period through the 3 months of follow-up after the changes involving the optic nerve heads and peripapillary vessels were observed (a total of 33 months). CONCLUSIONS: This report provides a description of the ocular manifestations of neonatal onset multisystem inflammatory disease and supports earlier suggestions that swelling of the optic nerve heads can occur. In this case, optic nerve head pallor may have been a sequela of such swelling. The pathogenesis of neonatal onset multisystem inflammatory disease is unknown.- - - - - - - - - - ranking = 18.678280833034keywords = nervous system (Clic here for more details about this article) |
4/38. Neuropsychological profile of a 9-year-old child with subcortical band heterotopia or 'double cortex'.Subcortical band heterotopia (SBH) or 'double cortex', is a congenital brain abnormality that results from aberrant migration of neurons during development of the cortex. MRI shows a continuous band of heterotopic grey matter located between the cortex and ventricular walls, separated from them by a thin layer of white matter. The condition is quite rare, found predominantly in females, and is occasionally familial with an X-linked dominant inheritance. Current research has focused on genetic and neurological correlates, with cognitive assessment restricted to a global measure of general intellectual functioning. This paper describes in detail the results of a neuropsychological assessment of a 9-year-old female recently diagnosed with SBH. Predominant features were a significantly reduced speed of processing for visuomotor and oral output and reduced immediate registration of information. This difficulty has functional implications affecting skill acquisition, learning in the classroom, and social interaction.- - - - - - - - - - ranking = 1keywords = neurologic (Clic here for more details about this article) |
5/38. Neurological presentation of three patients with 22q11 deletion (CATCH 22 syndrome).Chromosome 22q11 deletion (CATCH 22 syndrome or velocardiofacial syndrome) is one of the most frequent chromosomal syndromes. Neurological features other than cognitive disorders are probably the least-described part of the expanding phenotype of the 22q11 deletion. We report the neurological features of three unrelated children with a de novo deletion: one patient with an autistic disorder, a second patient with hypocalcaemic neonatal seizures and unusual persistent epileptic focus at electroencephalographic follow-up, and a third patient with atypical absence epilepsy. These observations enlarge the clinical and neurological spectrum of the 22q11 deletion. awareness of such cases is necessary, and a diagnosis of the 22q11 deletion should be suspected in children with common neurological features associated with severe or mild dysmorphism. diagnosis of the 22q11 deletion should be confirmed by fluorescence in situ hybridization analysis associated with standard chromosomal analysis.- - - - - - - - - - ranking = 3keywords = neurologic (Clic here for more details about this article) |
6/38. septo-optic dysplasia with olfactory tract and bulb hypoplasia.optic nerve hypoplasia can be associated with other central nervous system malformations. When associated with absence of the septum pellucidum or thinning of the corpus callosum, it is termed septo-optic dysplasia. Considered to be a first trimester event, the embryologic timing and etiology of this syndrome still is not clearly defined. This report represents the first documented case of septo-optic dysplasia with associated hypoplasia of the olfactory tract. optic nerve hypoplasia is attributed to an abnormal developmental process during gestation. Generally accepted to be due to a first trimester insult, the timing of this abnormality has been debated given its association with other central nervous system abnormalities. These central nervous system abnormalities often include cerebral hemispheric and hypothalmic-pituitary axis abnormalities. Specifically, the presence of optic nerve hypoplasia with absence of the septum pellucidum and thinning of the corpus callosum has been termed septo-optic dysplasia or de Morsier's syndrome. septo-optic dysplasia in association with olfactory tract and bulb hypoplasia has not been reported previously.- - - - - - - - - - ranking = 56.034842499102keywords = nervous system (Clic here for more details about this article) |
7/38. Neurological manifestations of the oculodentodigital dysplasia syndrome.Oculodentodigital dysplasia (ODDD) (MIM 164200) is a rare autosomal dominant inherited disorder affecting the development of the face, eyes, limbs and dentition. Neurological complications are thought to be occasional manifestations of the disorder. This report illustrates the neurological manifestations by a pedigree of two ODDD patients with spastic paraparesis, cerebral white matter hyperintensity and basal ganglia hypointensity. A systematic review of the English, French, German and Italian literature on ODDD is also provided to summarize the neurological manifestations of the disorder. 243 previously described ODDD cases presented a spectrum of neurological manifestation including spasticity (25), subcortical white matter lesions (9) and basal ganglia changes (6) on MRI. Additional findings consisted of gaze palsy and squinting (28), bladder and bowel disturbances (21), visual loss (20) and blindness (4), hearing loss (15), ataxia (11), nystagmus (9), muscle weakness (5) and paresthesias (3). Neurological manifestations, including spasticity associated with MRI changes, are an underrecognized feature in the ODDD phenotype. A clinical guide to the neurological manifestations of ODDD may assist in the assessment of patients with this condition.- - - - - - - - - - ranking = 4keywords = neurologic (Clic here for more details about this article) |
8/38. Relationship of neurologic degeneration to genotype in three xeroderma pigmentosum group G patients.We studied three newly diagnosed xeroderma pigmentosum complementation group G patients with markedly different clinical features. An Israeli-Palestinian girl (XP96TA) had severe abnormalities suggestive of the xeroderma pigmentosum/cockayne syndrome complex including sun sensitivity, neurologic and developmental impairment, and death by age 6 y. A Caucasian girl (XP82DC) also had severe sun sensitivity with neurologic and developmental impairment and died at 5.8 y. In contrast, a mildly affected 14-y-old Caucasian female (XP65BE) had sun sensitivity but no neurologic abnormalities. XP96TA, XP82DC, and XP65BE fibroblasts showed marked reductions in post-ultraviolet cell survival and dna repair but these were higher in XP65BE than in XP82DC. XP96TA fibroblasts had very low XPG mRNA expression levels whereas XP65BE fibroblasts had nearly normal levels. Host cell reactivation of an ultraviolet-treated reporter assigned all three fibroblast strains to the rare xeroderma pigmentosum complementation group G (only 10 other patients previously reported). XP96TA and XP82DC cells had mutations in both XPG alleles that are predicted to result in severely truncated proteins including stop codons and two base frameshifts. The mild XP65BE patient had an early stop codon mutation in the paternal allele. The XP65BE maternal allele had a single base missense mutation (G2817A, Ala874Thr) that showed residual ability to complement xeroderma pigmentosum complementation group G cells. These observations agree with earlier studies demonstrating that XPG mutations, which are predicted to lead to severely truncated proteins in both alleles, were associated with severe xeroderma pigmentosum/cockayne syndrome neurologic symptoms. Retaining residual functional activity in one allele was associated with mild clinical features without neurologic abnormalities.- - - - - - - - - - ranking = 9keywords = neurologic (Clic here for more details about this article) |
9/38. Femoral-facial syndrome with malformations in the central nervous system.The femoral hypoplasia-unusual facies syndrome (FFS) is a very rare association of femoral and facial abnormalities. Maternal diabetes mellitus has been mainly involved as the causal agent. We report the second case of FFS with anomalies in the central nervous system (CNS) including corticosubcortical atrophy, colpocephaly, partial agenesis of corpus callosum, hypoplasia of the falx cerebri and absent septum pellucidum. The psychomotor development has been normal. We propose that the CNS defects observed in these patients are part of the spectrum of abnormalities in the FFS.- - - - - - - - - - ranking = 93.39140416517keywords = nervous system (Clic here for more details about this article) |
10/38. Second trimester diagnosis of Neu Laxova syndrome.This is the first report of a prenatally diagnosed case of Neu Laxova syndrome (NLS) from india. This also includes a case of NLS in monochorionic diamniotic twins and two more cases in which we were able to detect most of the features of NLS as early as 19 to 20 weeks by routine antenatal ultrasonography. Severe intrauterine growth retardation (IUGR), microcephaly, central nervous system (CNS) abnormality, joint contractures, and abnormal facies are the major diagnostic features observed in prenatal ultrasonography. risk factors such as consanguinity and history of intrauterine death or stillbirth in siblings have been noted in all the cases, but none of the three families that were reported had previously had an affected fetus. The spectrum of skin manifestations and frequency of occurrence of major clinical features of the syndrome have been discussed. review of the literature on NLS and possibility of detecting the syndrome in the second trimester is discussed.- - - - - - - - - - ranking = 18.678280833034keywords = nervous system (Clic here for more details about this article) |
