Incidence of perinatal arterial stroke (ischemic stroke, intracerebral hemorrhage and subarachnoid hemorrhage) occurring between 20 weeks of gestation and postnatal day 28 ranges between 20 and 65 cases per 100,000 living births. In children aged 29 days to 18 years old, the total incidence is 1.3 to 4.3 for 100,000 per year. In France, almost 450 children are hospitalized for a stroke each year, among them approximately half have an intracerebral hemorrhage.

BACKGROUND: Cerebral palsy is the most common cause of motor disability in children with a prevalence of 2-10/1,000 live births in the developing areas. AIM: The epidemiology, clinical picture, and associated comorbidities in CP have been extensively studied in high-resource countries, but in low-resource areas, including Africa, those studies are still lacking. METHODS: Cerebral palsy cases were prospectively recruited from every physiotherapy centre in Bani-Mazar city, Egypt, in a cross-sectional study from May 2015 to November 2015...

Polychlorinated biphenyls (PCBs) are ubiquitous environmental toxicants known to adversely impact human health. Ortho-substituted PCBs affect the nervous system, including the brain dopaminergic system. The reinforcing effects of psychostimulants are typically modulated via the dopaminergic system, so this study used a preclinical (i.e., rodent) model to evaluate whether developmental contaminant exposure altered intravenous self-administration (IV SA) for the psychostimulant cocaine. Long-Evans rats were perinatally exposed to 6 or 3 mg/kg/day of PCBs throughout gestation and lactation and compared with nonexposed controls...

Few high-income countries have an active national programme of stillbirth audit. From the three national programmes identified (UK, New Zealand, and the Netherlands) steady declines in annual stillbirth rates have been observed over the audit period between 1993 and 2014. Unexplained stillbirth remains the largest group in the classification of stillbirths, with a decline in intrapartum-related stillbirths, which could represent improvements in intrapartum care. All three national audits of stillbirths suggest that up to half of all reviewed stillbirths have elements of care that failed to follow standards and guidance...

The Affordable Care Act mandates that public health data be made available for community agency use. Having access to such data allows community agencies to tailor interventions, evaluations, and funding requests more effectively. This study, jointly undertaken by Syracuse University faculty and students with the New York State Perinatal Association, sought to understand community agencies' access to requests for governmental data, as well as to identify areas for improving data access. Results from this survey of administrators from 43 agencies in New York State found that only one-half of their requests for data were successful...

Bisphenol A (BPA) is an endocrine-disrupting chemical (EDC) prevalent in many household items. Rodent models and human epidemiological studies have linked this chemical to neurobehavior impairments. In California mice, developmental exposure to BPA results in sociosexual disorders at adulthood, including communication and biparental care deficits, behaviors that are primarily regulated by the hypothalamus. Thus, we sought to examine the transcriptomic profile in this brain region of juvenile male and female California mice offspring exposed from periconception through lactation to BPA or ethinyl estradiol (EE, estrogen present in birth control pills and considered a positive estrogen control for BPA studies)...

BACKGROUND: We aimed to determine whether maternal antenatal or perinatal infections (and thereby use of antibiotics) increase the risk of developing inflammatory bowel disease (IBD) in their offspring. METHODS: The University of Manitoba IBD Epidemiology Database contains records of all Manitobans diagnosed with IBD from 1984 to 2010. Each individual with IBD is matched to 10 controls. Subjects' medical system contacts are identified using a unique deidentified personal health identification number...

REVIEW
O D Howes, R McCutcheon
An interaction between external stressors and intrinsic vulnerability is one of the longest standing pathoaetiological explanations for schizophrenia. However, novel lines of evidence from genetics, preclinical studies, epidemiology and imaging have shed new light on the mechanisms that may underlie this, implicating microglia as a key potential mediator. Microglia are the primary immune cells of the central nervous system. They have a central role in the inflammatory response, and are also involved in synaptic pruning and neuronal remodeling...

Chikungunya is a mosquito-borne infectious disease that has emerged as a global pathogen. The virus can pass vertically from mother to child especially during the perinatal period, with an intrapartum vertical transmission rate of 50%. Approximately half of the neonates infected with chikungunya present with severe symptoms and infrequently death. This report summarizes two severe cases of vertically transmitted neonatal chikungunya infection. One case was confirmed by real-time reverse transcription polymerase chain reaction and the other fulfilled clinical and epidemiological criteria...

The ultrasonographic measurement of cervical length with a cutoff of 15mm is currently the best method to identify a group of asymptomatic women in the general population at risk of spontaneous preterm birth, especially among asymptomatic patients with a singleton pregnancy with no history of preterm birth. Cerclage and 17 alpha-hydroxyprogesterone caproate (17OHP-C) are ineffective to reduce the risk of preterm birth among asymptomatic patients with a short cervix in midtrimester. However, vaginal progesterone (200-mg capsules of micronized progesterone or gel containing 90mg progesterone) has been demonstrated effective in 2 large randomized trials to reduce the risk of preterm birth and possibly the composite morbidity and perinatal mortality associated among asymptomatic women with a short cervix in the general population screened by ultrasound of the cervix in midtrimester...

BACKGROUND: An inverse association between maternal smoking and preeclampsia has been frequently observed in epidemiologic studies for several decades. In the May 2015 issue of this journal, Lisonkova and Joseph described a simulation study suggesting that bias from left truncation might explain the inverse association. The simulations were based on strong assumptions regarding the underlying mechanisms through which bias might occur. METHODS: To examine the sensitivity of the previous authors' conclusions to these assumptions, we constructed a new Monte Carlo simulation using published estimates to frame our data generating parameters...

BACKGROUND: Three-quarters of the burden of mental health problems occurs in low-and-middle-income countries, but few epidemiological studies of these problems in preschool children from sub-Saharan Africa have been published. Behavioural and emotional problems often start in early childhood, and this might be particularly important in Africa, where the incidence of perinatal and early risk factors is high. We therefore aimed to estimate the prevalence and risk factors of behavioural and emotional problems in young children in a rural area on the Kenyan coast...
