RESUMO

We report the case of an infant born with congenital Zika syndrome (CZS). During the largest Zika virus (ZIKV) outbreak in Peru, the mother presented with fever and rash that were confirmed to be due to ZIKV by real-time PCR. The infant was born with severe microcephaly. Imaging revealed corpus callosum dysgenesis, lissencephaly, ventriculomegaly, and calcifications. Mild hypertrophic cardiomyopathy with diastolic dysfunction was reported in the echocardiogram. Valgus deviation of the lower extremities and a left clubfoot were diagnosed at birth. The hip ultrasound showed incipient signs of Graf type II dysplasia. The findings confirm that CZS is a multiorgan phenotype in which microcephaly is merely the tip of the iceberg. A multidisciplinary approach is needed for the evaluation of these children.

RESUMO

RESUMEN La hidrocefalia congénita constituye un síndrome polimórfico, que reúne afecciones diversas que conllevan a la discapacidad mental y a la muerte, puede aparecer como una malformación aislada o asociarse a otras, relacionada con un gran número de defunciones. La mayoría de los casos diagnosticados prenatalmente no llegan al nacimiento, lo cual significa que es necesario la prevención preconcepcional de los factores de riesgo asociados, los cuales son disímiles y en su mayoría prevenibles. Se revisó la bibliografía actualizada en las bases de datos bibliográficas Scielo y ClinicalKey, además de tesis de terminación de las especialidades Embriología Médica, Ginecobstetricia, Pediatría y Medicina Interna. Entre los factores de riesgo asociados se destacan el déficit de ácido fólico, las infecciones maternas, así como agentes físicos y químicos. El objetivo fue exponer los referentes teóricos relacionados con la hidrocefalia congénita y sus factores asociados, basándose en los fundamentos teóricos más actualizados (AU).

SUMMARY Congenital hydrocephaly is a polymorphic syndrome comprising diverse diseases that lead to mental disability and death. It could appear like an isolated malformation or associated to other malformations and is related to a great number of deceases. Most of the cases diagnosed prenatally are not borne, meaning not only that incidence is slow, but also that a great work is needed in the pre-conceptive prevention of the associated risk factors that are different and mostly preventable and modifiable. That is why it is an important multifactorial health problem. Among the associated risk factors the most important are folic acid deficit, maternal infections, and also physical and chemical agents. The theoretical referents related to congenital hydrocephaly and its associated factors are declared the aim of this research on the basis of the most updated theoretical principles (AU).

RESUMO

INTRODUCTION: Hydrocephalus is defined as complex conditions influenced by genetic and environmental factors. Excluding hydrocephalus acquired from infection or brain tumors, congenital hydrocephalus with a genetic cause may occur isolated (hydrocephalus isolated, pure or non-syndromatic) or as a component of a genetic syndrome (syndromic hydrocephalus). OBJECTIVE: To present a syndromic congenital hydrocephalus with a known diagnosis, in order to be considered in the study of this pathology and to perform a review of hydrocephaly with a genetic cause. CLINICAL CASE: Preschool with a prenatal diagnosis of hydrocephalus and rhombencephalosynapsis, karyotype and study of TORCH was normal. At the moment of birth, the prenatal diagnoses were confirmed and a malformation of cerebral cortical development was excluded. During the first week of life, perito neal ventricle shunt was performed. A reevaluation at age 4, the absence of corneal reflexes bilate ral parietal and congenital focal alopecia associated with rhombencephalosynapsis, meet definitive criteria for cerebello-trigeminal-dermal displasia or Gómez-López-Hernández syndrome (GLHS). CONCLUSIONS: GLHS is an uncommon neurocutaneous syndrome, possibly a sporadic condition that is underdiagnosed. Due to the new imaging and genetic technologies pre and post-natal, today it is possible to achieve a better and more accurate diagnosis of hydrocephalus with a genetic origin, in which the high suspicion of teams of clinical specialists is essential. Without accurate diagnosis, we can not access to a long-term prognosis, prevention of aggregate morbidity or an adequate genetic counseling, which are required in today's pediatrics.

RESUMO

Resumen: Introducción: Las hidrocefalias son condiciones complejas influenciadas por factores genéticos y ambientales. Excluyendo las hidrocefalias adquiridas por infección o tumores encefálicos, las hidrocefalias congénitas de causa genética pueden ocurrir de forma aislada (hidrocefalia aislada, pura o no sindromática) o como componente de un síndrome genético definido (hidrocefalia sindromática). Objetivo: Presentar una hidrocefalia congénita sindromática con un diagnóstico co nocido, y realizar una revisión de la literatura. Caso clínico: Preescolar con diagnóstico prenatal de hidrocefalia y romboencefalosinapsis, cariotipo y estudio de TORCH normales. Al nacer se confirmaron los diagnósticos prenatales y se excluyó malformación del desarrollo cortical cerebral. En la primera semana de vida se realizó derivación ventrículo peritoneal. En una reevaluación a la edad de 4 años, la ausencia de reflejos corneales y alopecia parietal bilateral asociado a romboencefalosinapsis reunieron los criterios diagnósticos definitivos de una displasia cerebelo-trigémino dermal (Síndrome de Gómez, López-Hernández (SGLH)). Conclusiones: El SGLH es un síndro me neurocutáneo infrecuente, posiblemente una condición esporádica que está subdiagnostica da. Con las nuevas tecnologías imageneológicas y genéticas pre y post natales podemos acceder a un diagnóstico de precisión de las hidrocefalias de origen genético, en el cual la alta sospecha de equipos de especialistas clínicos es esencial. Sin el diagnóstico preciso no podemos acceder a un pronóstico a largo plazo, prevención de morbilidad agregada y un consejo genético adecuado, que son requeridos en la pediatría actual.

RESUMO

BACKGROUND: In the management of hydrocephalus, the ventriculo-gallbladder shunt is justified in situations where the ventriculo-peritoneal shunt is not useful due to peritoneal involvement and/or when the ventriculo-auricular and ventriculo-pleural shunts are contraindicated. CLINICAL CASE: A 27 year-old female with hydrocephalus at birth, managed with ventricle-peritoneal shunt, modified 3 times throughout her life due to repeated infections and other different reasons. She was admitted due to colitis caused by Clostridium difficile, presenting concomitant signs of intracranial hypertension and neurological impairment. This led to a review and change of the ventriculo-peritoneal shunt system, with distal dysfunction due to peritoneal thickening. Atrial and pleural shunts were not indicated because the risk of infection. As an alternative, it was decided to place the distal end of the catheter in the gallbladder. The patient recovered her neurological functions after the surgery. CONCLUSIONS: Drainage alternatives may be needed in 5% of patients with valvular shunt dysfunction. The ventriculo-gallbladder is a good and viable option because it has an absorptive capacity of 1500cc liquid daily, besides being an excellent drainage through the bile duct. The abdominal surgery is easy to perform, and it is an alternative option in the failure of the ventriculo-peritoneal shunt.

RESUMO

Background: Hydrocephalus is a condition characterized by increased cerebrospinal fluid volume, with progressive dilatation of the ventricular system, with subsequent destruction and atrophy of the brain parenchyma. The congenital form is the most observed in the first months of life and occurs more frequently in small breed dogs. Because of the importance of this disease in the differential diagnosis in young dogs with signs cortical thalamus and the lack of national literature on the subject, the objective of this report was to present ten cases of congenital hydrocephalus in dogs and information about the race, sex, age, neurological signs, the findings of complementary tests and response to therapy. Cases: Ten dogs were referred to the Veterinary Medical Teaching Hospital of the UFSM, being three mixed breed dogs, two Lhasa apso, two Dachshunds, one Poodle, one English Bulldog and one Yorkshire terrier, aged between one month and one year and six months, seven females and three males. In all cases, the owners reported during anamnesis, altered level of consciousness (drowsiness or hallucination) and behavior and learning difficulties. For anatomical location of the lesion was performed complete neurological examination. As complementary tests were requested hemogram and serum biochemistry. In some individuals was performed analysis of cerebrospinal fluid by puncturing the...

RESUMO

Introducción: la agenesia sacra es una malformación congénita rara que forma parte del síndrome de regresión caudal. Se caracteriza por un grupo de anomalías en las cuales la columna caudal está ausente. Esta enfermedad es la malformación más frecuente en los hijos de madres diabéticas, además se ha relacionado con otros factores predisponentes, como deficiencias de ácido fólico, de vitaminas, uso de insulina en el embarazo, e incluso, la hipoxia. Entre un 30-40 por ciento de pacientes con agenesia sacra completa, pueden tener asociado un mielomeningocele, y el desplazamiento de las raíces nerviosas empeora los trastornos neurológicos. En estos casos, la hidrocefalia, muchas veces también asociada a malformación Chiari tipo II, está ya presente al nacer. Caso clínico: se presenta el caso de un neonato con agenesia sacra asociada a disrrafismo espinal e hidrocefalia. La intervención quirúrgica fue precoz, se le colocó derivación ventrículo peritoneal y se realizó la reparación del defecto del tubo neural. La evolución posoperatoria fue favorable, aunque persistieron los déficits neurológicos preoperatorios. Conclusiones: no se hallaron factores predisponentes en este paciente y el análisis del cariotipo fue normal. Las anomalías óseas de miembros inferiores fueron las más llamativas, así como la presencia de hidrocefalia asociada a malformación Chiari tipo II y mielomeningocele. El tratamiento a estos casos requiere de un enfoque multidisciplinar, y la reparación quirúrgica del mielomeningocele debe ser precoz para conseguir una evolución favorable. Las formas graves pueden ocasionar una muerte temprana neonatal, en cambio, los niños que sobreviven, generalmente presentan inteligencia normal

Introduction: sacra agenesia is a rare congenital malformation as part of the caudal regression syndrome. It is characterized by a group of anomalies in which the caudal cord is absent. This disease is the most common malformation found in children from diabetic mothers but it has also been related to other predisposing factors such as folic acid deficiencies, vitamin deficiencies, use of insulin at pregnancy and even hypoxia. Thirty to forty percent of patients with complete sacra agenesia can also have myelomeningocele, and the displacement of nerve roots worsens the neurological disorders. In these cases, hydrocephaly, many times associated to Chiari malformation type II, is also present at birth. Clinical case: a neonate with sacra agenesia associated to spinal dysraphism and hydrocephaly. Surgical intervention was performed early, a peritoneal ventricular derivation was placed and the neural tube defect was repaired. The post-surgery evolution was favorable, but the preoperative neurological deficits persisted. Conclusions: there were no predisposing factors in this patient and the analysis of the cariotype was normal. The bone anomalies of the lower members were the most remarkable aspects as well as the hydrocephaly associated to Chiari malformation type II and myelomeningocele. The treatment of these cases requires multidisciplinary approach and surgical repair of the myelomeningocele at early phase to achieve favorable evolution. The most severe forms can cause early neonatal death; however, those surviving children generally present normal intelligence coefficient

RESUMO

PURPOSE: Congenital hydrocephalus (CH) has higher proportions in developing countries such as Brazil, reaching rates of 3.16:1,000 newborns. Early diagnosis is essential and can be done during the second trimester of pregnancy, highlighting the importance of regular prenatal care. Our objective is to describe the epidemiological profile of children with CH in the state of Bahia. METHODS: Consecutive medical records of patients with CH, aged less than 2 years and operated at a pediatric reference hospital between September 2009 and September 2012, were reviewed. RESULTS: One hundred twenty-one children underwent ventricular peritoneal shunt (VP shunt) due to CH. As for prenatal care, 38% of pregnant women did it regularly. Males predominated with 56% of cases with a median age of 3 months, and 68% were from the countryside area. The most frequent clinical manifestations were bulging fontanelle (37%) and increased head circumference (30%). There were 13 (11%) reports of complications associated with VP shunts. There were nine deaths (7%), and respiratory complications were the main cause. CONCLUSIONS: Public health measures are the key to increase mothers' knowledge about the importance of regular prenatal monitoring. There was a predominance of male children, with a median age of 3 months, with the majority coming from the countryside.

RESUMO

The meningocele is the least common form of spina bifida cystica and represents less than 10% of cases of this disorder. A case of a female patient aged 26 with a history of two pregnancies and two previous cesarean sections, present pregnancy unplanned, uncontrolled during the first trimester prenatal and without supplementation with folic acid. Family history of consanguinity with her husband (second cousins) and psychomotor reassessed in four maternal cousins. The first follow-up visit the patient was at 34 weeks of pregnancy. The ultrasonographic findings were: cervical meningocele posterior filiform connection between the first and second cervical vertebrae, lateral ventriculomegaly and third and fourth ventricles and hydrocephalus secondary. Cesarean section was performed at 37 weeks gestation and was a newborn male 3.000 g, 52 cm, head circumference of 36 cm, Apgar 8/9, Capurro 37 weeks of gestation. In the posterior cervical region tumor was located a soft 5 x 5 cm with intact skin, adhered to deep planes. Movement of all four extremities without neurological involvement. He referred to the department of neurosurgery for shunt placement and subsequently performed surgical excision of the meningocele.
