The authors studied retrospectively a series of 18 pediatric patients with APC. Signs and symptoms of shunt dysfunction were observed in 15 (83.3%), abdominal complaints in 10 (55.5%) and fever in 6 (33.3%). Prior to the diagnosis of APC, 2 patients suffered exploratory laparotomies due to important abdominal signs and symptoms. Ultrasonography was diagnostic in all cases and proved to be the method of choice in the evaluation of APC. Our series suggest that APC are strongly related to hardware infection and in some cases can result from a previous shunt infection not completely cured. The bacteriological examination of the tip of the peritoneal catheter was a reliable indicator of infection. According to our data, the best treatment seems to be the removal of the shunt system and the insertion of an external ventricular drainage. In our experience, almost half of the patients had ...

Estes métodos diagnósticos permitiram a identificação de diferentes subgrupos de tumores da região, alguns dos quais passíveis de extirpação cirúrgica, com sobrevida prolongada e eventual cura. Os autores apresentam dois casos de um peculiar grupo de rumores do tectum do mesencéfalo, cujos aspectos tomográficos e manifestações clínicas sugeriam estenose do aqueduto de Sylvius de início tardio. O diagnóstico definitivo foi estabelecido por RNM. Em ambos, os sintomas desapareceram após instalação de derivação ventricular. As características clínico-patológicas e as alternativas terapêuticas deste subgrupo particular de tumores do tronco encefálico são discutidas.

Infecções de derivações ventriculares foram três vezes mais freqüentes em portadores de spina bifida cística que no restante da população de hidrocéfalos tratados na instituição. Houve grande incidência de complicações pós-operatórias relacionadas a infecções e necrose de ferida cirúrgica. Onze pacientes (15,3%) desenvolveram sinais e sintomas relacionados à malformação de Chiari do Tipo II. A mortalidade foi 8,3% e, na maioria absoluta dos casos, associada à malformação de Chiari.

The congenital clubfoot has been found the most common orthopaedic anomaly in patients with MMC. The ankle-foot orthosis (AFO) is an orthopaedic device commonly used by these children to minimize the sequelae caused by this anomaly. Objective: Identify the functional benefits brought about by the use of the AFO to children with MMC, as reported by their guardians. Method: Descriptive, transversal study. Convenience sample consisting of 25 guardians of children with MMC who were using/had used an AFO. Results: Eighty percent of the guardians have reported at least one benefit brought about by the use of the AF...

Os autores apresentam mais um caso, mostrando as dificuldades diagnosticas principalmente quando nao ha aparente porta de entrada. Enfatizam, nestas circunstâncias, a importância de certos sinais clinicos, o valor da puncao lombar e da imagem por ressonância nuclear magnetica na elucidacao diagnostica. Este ultimo exame nao foi mencionado anteriormente na literatura consultada sobre o assunto. O tratamento cirurgico, associado a antibioticoterapia, mostrou-se bastante eficaz, principalmente se realizado precocemente (AU)

The authors stress that the so-called open dysraphism have the worst prognosis and that prophylaxis with folic acid can reduce its incidence.significantly. They also show that the closed or occult spinal dysraphisms have a better prognosis and that prophylactic surgery can prevent progression to irreversible neurological damage.

The current Brazilian outbreak brought up an unexpected increase in the number of microcephaly cases as this strain is essentially neurotropic and associated with devastating effects on the developing central nervous system.ObjectThis focus session aims to discuss the several issues related to the epidemiology, diagnosis, clinical features, and treatment of the congenital Zika virus infection.

Data were collected from medical records of children who underwent the primary repair of MMC at the Fernandes Figueira Institute–Oswaldo Cruz Foundation (IFF-Fiocruz) between January 1995 and January 2015, with a minimum follow-up of 1 year. The following variables were analyzed: demographic characteristics (gestational age, sex, and birth weight); clinical features (head circumference at birth, anatomical and functional levels of MMC, hydrocephalus, symptomatic Chiari malformation type II, neurogenic bladder, and urinary tract infection [UTI]); and surgical details such as timing of repair of MMC, age at first shunt placement, shunt surgery modality (elective or emergency), concurrent surgery ...

NCC is an important acquired cause of epilepsy and other neurological manifestations especially in endemic areas. NCC in children has pleomorphic manifestations depending on the location, number, viability of the cysts, and host response. Even with advancing knowledge of the disease manifestations, many aspects related to diagnosis and treatment, particularly in children, still remain controversial and pose challenges to clinical practice. There is no gold standard test to diagnose NCC and the management recommendations are still emerging. This review provides an overview of diagnosis of NCC in children and its management with special focus on current challenges and future prospects. In developing countries, NCC is important not only because of its frequency but also because of high morbidity and mortality rates associated, especially in cases in which it progresses to increa...

Methods: A retrospective study of 383 children born with myelomeningocele from January 1990 to December 2013 in a high-fetal-risk reference hospital. Results: A total of 39 patients died (10.1%),of which 23 (6%) died after discharge. Most children who died were younger than 12 months of age. The most frequent cause of death was infection of the central nervous system, followed by urinary tract sepsis and infections of the respiratory system. Symptomatic Chiari II malformation was the most frequent comorbidity factor. Conclusion: Although there was no significant difference in infant mortality before and after folic acid fortification, there was a significant reduction in deaths after hospital discharge in babies born after implementation of mandatory folic acid ...

In 1994, Kaufman et al. 16 associated the inadequate follow-up of these patients with high morbidity. In 2003, Oakeshott and Hunt reported the association of childhood neurological deficits with the ABBREVIATIONS CM-II = Chiari malformation type II; ETV = endoscopic third ventriculostomy; IFF-Fiocruz = Fernandes Figueira Institute-Oswaldo Cruz Foundation; MMC = myelomeningocele; NTD = neural tube defect; PFD = posterior fossa decompression; UTI = urinary tract infection.

To demonstrate that laparoscopic procedures for distal ventriculoperitoneal shunt failure may be an effective option for patients who underwent multiple revisions due to repetitive manipulation of the peritoneal cavity, abdominal pseudocyst, peritonitis or other situations leading to a "non reliable" peritoneum. From March 2012 to February 2013, the authors reviewed retrospectively the charts of six patients born and followed up at our institution, which presented with previous intra-peritoneal complications and underwent ventriculoperitoneal shunt revision assisted by video laparoscopy. After a mean follow-up period of nine months, all patients are well and no further shunt failure was identified so far. Laparoscopy assisted shunt revision in children may be, in selected cases, an effective option for patients with multiple peritoneal complic...
