The aim of this review is to determine the relationship between gestational age (GA) and prevalence, type, distribution, and severity of cerebral palsy (CP). Epidemiological studies with cohorts expressed by GA were assessed. A comprehensive meta-analysis and metaregression was performed on four fetal age categories. Studies of children with CP as a target population were added. Twenty-six articles met the inclusion criteria. The prevalence of CP decreases significantly with increasing GA category: 14.6% at 22 to 27 weeks' gestation, 6.2% at 28 to 31 weeks, 0.7% at 32 to 36 weeks, and 0.1% in term infants. Interestingly, a significant decrease in prevalence of CP starts only from a GA of 27 weeks onwards. In preterm infants, spastic CP is predominant. In term infants, the non-spastic form of CP is more prevalent than in preterm infants. Bilateral spastic CP is most prevalent in both preterm and term infants. However, the proportion of unilateral spastic CP in term infants is substantial. No relationship could be detected between severity of CP and GA. There is a strong need for an international, well-described, and generally accepted classification system for subtypes and severity of CP.Cerebral palsy (CP) is one of the most common and well-recognized neurodevelopmental conditions, beginning in early childhood and persisting through the lifespan. 1 It is generally accepted that the risk of CP decreases with increasing gestational age (GA) of live-born infants. 2 Registers of childhood impairments and large population-based studies in Europe, [3][4][5][6][7][8] Japan, 9 and North America 10 monitored trends in rates of CP according to GA but focused mainly on the diagnosis of CP as a parameter reflecting the quality of perinatal care. Other studies were very fractionized and focused mostly on extremely and very preterm infants 11-22 but failed to present an overview of all age categories. In contrast, in these latter studies regarding extremely preterm infants, the presented prevalence rates of CP for each week of gestation are rather inconsistent and do not subscribe to the assumption that increasing GA results in decreasing rates of CP.In this meta-analysis we reveal the characteristics of the association between GA and CP. While exploring prevalence rates of CP in relation to GA, we found in several articles a link between GA and type and distribution of CP. Therefore, we looked for a relationship between GA and the characteristics of CP; specifically the type, distribution, and severity of CP.

ABSTRACT. Objective. To determine mortality and morbidity at discharge from the hospital of a large population-based cohort of infants who were born at <26 weeks' gestation.Methods. Perinatal data were collected on extremely preterm infants who were alive at the onset of labor and born between January 1, 1999, and December 31, 2000, in all 19 Belgian perinatal centers.Results. A total of 525 infants were recorded. Lifesupporting care was provided to 322 liveborn infants, 303 of whom were admitted for intensive care. The overall survival rate of liveborn infants was 54%. Of the infants who were alive at the age of 7 days, 82% survived to discharge. Vaginal delivery, shorter gestation, air leak, longer ventilator dependence, and higher initial oxygen need all were independently associated with death; gender, plurality, and surfactant therapy were not. Among the 175 survivors, 63% had 1 or more of the 3 major adverse outcome variables at the time of discharge (serious neuromorbidity, chronic lung disease at 36 weeks' postmenstrual age, or treated retinopathy of prematurity). The chance of survival free from serious neonatal morbidity at the time of hospital discharge was <15% (21 of 158) for the admitted infants with a gestation <26 weeks.Conclusions. If for the time being prolongation of pregnancy is unsuccessful, then outcome perspectives should be discussed and treatment options including nonintervention explicitly be made available to parents of infants of <26 weeks' gestation within the limits of medical feasibility and appropriateness.

The average developmental outcome is poor in children born as extremely preterm infants. Finding early predictors of adverse outcome is a major challenge.

Acute renal failure due to tubulo-interstitial nephritis developed in a 15-year-old girl. The disease was accompanied by uveitis and an inflammatory syndrome, consisting of a markedly increased erythrocyte sedimentation rate and high serum gamma globulin levels. The nephropathy as well as the inflammatory syndrome subsided spontaneously. A topical antiphlogistic treatment healed the ocular disease, which has not relapsed so far. The association of acute tubulo-interstitial nephritis and acute uveitis observed in several patients has led to the identification of a specific syndrome with a very particular symptomatology and course, the so-called TINU syndrome, the interest of which resides in the predictability of the complete reversibility of the nephropathy either spontaneously or after steroid treatment, contrasting with the marked tendency towards relapse of the uveitis. The demonstration of circulating immune complexes in the serum during the acute phase of the illness, as in our patient, further points to the involvement of immune processes in the syndrome, but the origin and pathogenesis remain as yet unknown.

Objective.To analyze trends in the incidence and pathogen distribution of healthcare-associated bloodstream infections (HABSIs) over a 20-year period (1992–2011).Design.Historical cohort study.Setting.Thirty-two-bed neonatal intensive care unit (NICU) in a tertiary referral hospital.Patients.Neonates with HABSIs defined according to the criteria of the National Institute of Child Health and Development (NICHD).Methods.A hospital-based ongoing surveillance program was used to identify HABSI cases in neonates. A distinction between definite or possible HABSI was made according to the NICHD criteria. Incidence, incidence densities (HABSIs per 1,000 hospital-days and HABSIs per 1,000 total parenteral nutrition–days), and case fatality rate were calculated. Logistic regression analysis was used to find time trends. Four periods of 5 years were considered when executing variance analysis.Results.In total, 682 episodes of HABSIs occurred on 9,934 admissions (6.9%). The median total incidence density rate was 3.1 (interquartile range, 2.2–3.9). A significant increasing time trend in incidence density was observed for the period 1995–2011 (P < .003). A significant decrease in the case fatality rate was found in the last 5-year period (P < .001). No neonate died following possible HABSIs, whereas the case fatality rate among neonates with definite HABSIs was 9.7%. Most HABSIs were caused by coagulase-negative staphylococci (n = 414 [60.7%]). A significant increase in Staphylococcus aureus HABSI was observed in the last 10-year period (P < .001).Conclusions.An increase in incidence density rate occurred, while the case fatality rate dropped. Better perinatal care could be responsible for the latter. A decrease in days before infection and a high incidence of coagulase-negative Staphylococcus HABSIs indicate the need for vigorous application of evidence-based prevention initiatives, in particular for catheter care.

In a population of 27 flemish newborns with subgaleal bleeding encountered within a period of 6 years, we studied the obstetrical, clinical and radiological data. In contrast with controversial findings from the available literature, there is little doubt that difficult, often elective vacuum extraction is the main cause of this neonatal emergency. Disturbances in haemostasis, when documented, were attributed to focal intrahaematoma consumption, except for one boy who presented with haemophilia and neonatal subgaleal bleeding. Conventional X-ray examination continues to be of importance for the documentation of suture diastasis, fissures and fractures. CT scan reveals both the amount of extra-osseous bleeding, the degree of bone displacement and injury as well as the type and extent of associated intracranial damage. Subgaleal haemorrhage rarely hides a growing synchrondrosal rupture.

In approximately 20% of individuals with Kagami-Ogata syndrome (KOS14, MIM 608149), characterized by a bell-shaped thorax with coat-hanger configuration of the ribs, joint contractures, abdominal wall defects and polyhydramnios during the pregnancy, the syndrome is caused by a maternal deletion of the imprinted gene cluster in chromosome 14q32.2. Most deletions reported so far included one or both of the differentially methylated regions (DMRs) - DLK1/MEG3 IG-DMR and MEG3-DMR. We present two unrelated families with two affected siblings each, presenting with classical KOS14 due to maternally inherited microdeletions. Interestingly, all four patients have lived through to adulthood, even though mortality rates for patients with KOS14 due to a microdeletion are relatively high. In the first family, none of the DMRs is included in the deletion and the methylation status is identical to that of controls. Deletions that do not encompass the DMRs in this region are thus sufficient to elicit the full KOS14 phenotype. In the second family, a partially overlapping deletion including both DMRs and MEG3 was detected. In summary, we show that patients with KOS14 can live into adulthood, that causal deletions do not have to include the DMRs and that consequently a normal methylation pattern does not exclude KOS14.
