RESUMEN

INTRODUCCIÓN: El Síndrome Cornelia de Lange (SCdL), es un trastorno congénito del desarrollo, se presenta en descendencia de padres consanguíneos. Prevalencia de 0,2 a 1 por 10.000 nacidos vivos. Existe evidencia de cromosomopatías 3q25-29 y 5p13-14. Presenta un fenotipo facial característico con microcefalia, sinofridia, pestañas largas, labios en V-invertida, además de hipertricosis, oligodactilia, retraso del desarrollo psicomotor, y cardiopatías. El objetivo es establecer los antecedentes médicos relevantes para diagnosticar de forma precoz la enfermedad. CASO CLÍNICO: Niña de 16 meses de edad, padres consanguíneos, nacida prematura de 36 semanas, se le diagnostica un SCdL grave, además tiene cardiopatía congénita, riñones poliquísticos, hipoacusia severa, reflujo gastroesofágico complicándose con neumonía por aspiración. DISCUSIÓN: El diagnóstico se realiza con examen físico y cariograma. Considerar el Síndrome Alcohólico Fetal como diagnóstico diferencial. Para el tratamiento, es fundamental seguir las pautas del 2007 para el manejo de individuos con SCdL, así prevenir complicaciones respiratorias.

INTRODUCTION: Cornelia de Lange Syndrome (CdLS), is a congenital developmental disorder, occurs in offspring of consanguineous parents. The prevalence is 0.2 to 1 per 10,000 live births. There are evidence of chromosomopathies 3q25-29 and5p13-14. The affected have a characteristic facial phenotype with microcephaly, synophrys, long eyelashes, V-shaped invertedlips, hypertrichosis, oligodactyly, psychomotor retardation, and heart disease. The aim is to establish the relevant medical background for early diagnosis of the disease. CASE REPORT: Girl, 16 months old, consanguineous parents, born 36 weeks premature, diagnosed with a severe CdLS, congenital heart disease, polycystic kidneys, severe bilateral hearing loss, gastroesophageal reflux complicated by aspiration pneumonia. DISCUSSION: The diagnosis of CdLS is made by physical exam and karyotype. Fetal Alcohol Syndrome is the differential diagnosis. For treatment, it is essential to follow the 2007's guidelines for the management of individuals with CdLS and prevent respiratory complications.

RESUMEN

Dysphagia is common in children with severe developmental disabilities. The nature of these difficulties can predispose them to foreign body ingestion. This article presents a case that highlights the need for vigilance in diagnosing dysphagia in children with multiple and complex developmental disabilities where severe cognitive impairment and an inability to communicate may mask the presence of underlying problems.

RESUMEN

The Brachmann de Lange syndrome (BDLS), first described in its full clinical presentation by Brachmann (1916) and Cornelia de Lange (1933) is a multi-system syndrome involving congenital malformations, growth retardation and neurodevelopmental delay. We describe here twelve Egyptian cases with this syndrome with emphasis on the orodental, ear and eye abnormalities and their relation to the severity of expreseion of the disorder. The crodental anomalies were high arched palate, Iong philtrum, micrognathia, macrostomia hypoplasia of upper anterior teceth, fissured tongue macroglossia. Ear malformations were low-set large ears. Otoscopy revealed normal drum appearance. Audiogram revealed conductive, sensorineural or mixed hearing loss. Ocular manifestations were nystagmus, convergentt squint, enophthalmos, myopia 8 blue scleca. The study emphasizes certain eye, ear and crodental anomalies as diagnostic features of the BDLS which correlate with the severity of expression of the syndrome. None of the cases had chromosomal aberrations and the parental consanguinity rate was not increased thus supporting dominant mutations or minor chromosomal etiology.

RESUMEN

Seven patients, including two sibs, with the Brachmann-de Lange syndrome (BDLS) are presented as representative of the different types of BDLS in a proposed classification system. Type I ("classic") patients have the characteristic facial and skeletal changes of BDLS using the criteria in the diagnostic index of Preus and Rex. Type I is distinguished from the other subtypes by prenatal growth deficiency (< 2.5 S.D. below mean for gestation) becoming more severe postnatally (< 3.5 S.D. below the mean), moderate to profound psychomotor retardation, and major malformations which result in severe disability or death. Type II ("mild") BDLS patients have similar facial and minor skeletal abnormalities to those seen in type I; however, these changes may develop with time or may be partially expressed. Patients with type II BDLS are distinguished from those with other types by mild to borderline psychomotor retardation, less severe pre- and postnatal growth deficiency, and the absence of (or loss severe) major malformations. Behavioral problems can be a significant clinical problem in type II BDLS. Type III ("phenocopies") BDLS includes patients who have phenotypic manifestations of BDLS which are causally related to chromosomal aneuploidies or teratogenic exposures.

RESUMEN

Brachmann-de Lange syndrome (BDLS) is a relatively common multiple congenital anomaly/mental retardation syndrome, whose cause is unknown. The clinical variability of this condition is well-known. Recently some reports suggested the possible existence of a mild BDLS phenotype. We report on 30 patients in whom a diagnosis of BDLS was made or strongly suspected in 12 different Italian hospitals. Based on clinical evaluation we divided them into two groups, classical and mild BDLS cases. We compare the clinical data of these patients and we discuss the problems which arise in trying to define clear criteria of distinction between these two groups.

RESUMEN

A mother of normal intelligence and her moderately mentally retarded son, both with the typical facial features of the Brachmann-de Lange syndrome, are reported. We discuss the variable expression of the Brachmann-de Lange syndrome by comparing the autosomal dominant cases with the sporadic or presumed autosomal recessive cases. The autosomal dominant cases show milder symptoms in general. In our opinion, a de novo autosomal dominant mutation causes the severe form of the syndrome, recurrence within sibships being explained by germline mosaicism. In all convincingly autosomal dominant cases we found that the mother is the transmitting parent, suggesting genomic imprinting.

RESUMEN

We have classified patients referred for suspicion of the Brachmann-De Lange syndrome (BDLS) into two groups using techniques of numerical taxonomy. Patients with the syndrome share an array of abnormal characteristics, and those without it have different abnormal characteristics. A group of 30 characters that best distinguish the two groups of patients was used to construct a diagnostic index. The index score is expected to divide 99% of patients into those with and without the syndrome, leaving 1% in a "zone of doubt." All 46 patients used to construct the index and 16 new patients had scores in either the BDLS or non-BDLS range and none were in the zone of doubt. A previously published index using metacarpal-phalangeal measurements, although less discriminatory, confirmed our findings in 84% of 25 patients tested, the remainder having scores in the zone of doubt for that index.

RESUMEN

The concentration of human platelet lactogen (hPL), pregnancy specific beta-1 glycoprotein (SP-1) and pregnancy-associated plasma protein A (PAPP-A) were analysed in consecutive serum samples from a patient who gave birth to a child with Cornelia de Lange syndrome. HPL and SP-1 were present in normal concentrations from week 20 to week 35 of gestation whereas PAPP-A could not be detected in any of the samples examined. Immunohistochemical examination of two placentae from Cornelia de Lange syndrome revealed normal localization of hPL and SP-1 but the absence of PAPP-A from the syncytiotrophoblast. The significance of association between Cornelia de Lange syndrome and compromised synthesis of PAPP-A is discussed.
