Neonatal pain, parenting stress and interaction, in relation to cognitive and motor development at 8 and 18 months in preterm infants.

Procedural pain in the neonatal intensive care unit triggers a cascade of physiological, behavioral and hormonal disruptions which may contribute to altered neurodevelopment in infants born very preterm, who undergo prolonged hospitalization at a time of physiological immaturity and rapid brain development. The aim of this study was to examine relationships between cumulative procedural pain (number of skin-breaking procedures from birth to term, adjusted for early illness severity and overall intravenous morphine exposure), and later cognitive, motor abilities and behavior in very preterm infants at 8 and 18 months corrected chronological age (CCA), and further, to evaluate the extent to which parenting factors modulate these relationships over time. Participants were N=211 infants (n=137 born preterm 32 weeks gestational age [GA] and n=74 full-term controls) followed prospectively since birth.

Acute transverse myelitis and acute disseminated encephalomyelitis in childhood: spectrum or separate entities?

The clinical and radiological features of childhood acute transverse myelitis are compared to those of acute disseminated encephalomyelitis with spinal cord involvement in 22 children with acute transverse myelitis and 12 children with acute disseminated encephalomyelitis with spinal cord involvement. Children with acute transverse myelitis were more likely to have a sensory level (55%) and areflexia. Sixty-eight percent of the children with acute transverse myelitis, and 92% of children with acute disseminated encephalomyelitis had longitudinally extensive transverse myelitis.

Prediction of type 2 diabetes using alternate anthropometric measures in a multi-ethnic cohort: the insulin resistance atherosclerosis study.

Objective: To compare different anthropometric measures in terms of their ability to predict type 2 diabetes and to determine whether predictive ability was modified by ethnicity.

Research Design And Methods: Anthropometry was measured at baseline for 1,073 non-Hispanic white (nHW), African American (AA), and Hispanic (HA) subjects, of whom 146 developed type 2 diabetes after 5.2 years.

School injury among Ottawa-area children: a population-based study.

Background: Injuries are the leading cause of death among Canadian children and are responsible for a substantial proportion of hospitalizations and emergency department visits. This investigation sought to identify the factors associated with the likelihood of sustaining an injury at school among Ottawa-area children.

Methods: Children presenting to Ottawa-area hospitals and urgent care clinics from January to December 2002 (n = 24,074) were included for analysis.

A survey of the 16 Canadian child and youth protection programs: A threadbare patchwork quilt.

Background: Child abuse and neglect (CAN) represents an international public health and societal problem, the extent and nature of which are inadequately understood. Child and youth protection programs (CYPPs), based in 16 Canadian paediatric academic health science centres, identify, manage, treat and prevent cases of CAN.

Objectives: To ascertain the structure, resources and functioning of Canadian CYPPs.

Does epilepsy occur more frequently in children with Type 1 diabetes?

Aim: Hypoglycaemic seizures are common in children with diabetes and electroencephalogram abnormalities are well recognised in this patient group. Elevated antibodies to glutamic acid decarboxylase, a major auto-antigen in Type 1 diabetes, are also implicated in a number of neurological disorders. Despite these associations, the question of whether children with diabetes are more prone to epilepsy, possibly as a result of lowered seizure threshold, has not been previously studied.

Life experience with death: relation to death attitudes and to the use of death-related memories.

The study examines the relation of death experience to death attitudes and to autobiographical memory use. Participants (N = 52) completed standard death attitude measures and wrote narratives about a death-related autobiographical memory and (for comparison) a memory of a low point. Self-ratings of the memory narratives were used to assess their functional use.

Development, impact, and measurement of enhanced physical diagnosis skills.

Evidence suggests that the quality and frequency of bedside clinical examination have declined. We undertook the study to (1) determine whether intensive instruction in physical examination enhances medical student skills and (2) develop a tool to evaluate those skills using a modified observed structured clinical examination (OSCE). This was a randomized, blinded, prospective, year-long study involving 3rd year students at the Albert Einstein College of Medicine.

Identification of DNA-reactive B cells in patients with systemic lupus erythematosus.

Autoreactive B cells play a central role in systemic lupus erythematosus (SLE). Characterization of DNA-reactive B cells in the blood of lupus patients has been limited by the low frequency of the population. Using a tetrameric configuration of a peptide mimetope of DNA, we identified peptide-reactive B cells in peripheral blood.

Examining the sensitivity of an injury surveillance program using population-based estimates.

This study uses population-based estimates to assess the sensitivity and representativeness of an injury surveillance system using a 1-year population-based approach. Data from the Ottawa Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP) site (Children's Hospital of Eastern Ontario) were compared with those from six expansion sites. The overall sensitivity of CHIRPP was 43% of all treated injuries and 57% of injuries treated at emergency departments.

Accuracy of bedside electroencephalographic monitoring in comparison with simultaneous continuous conventional electroencephalography for seizure detection in term infants.

Objective: Our goals were to compare (1) single-channel amplitude-integrated electroencephalography alone, (2) 2-channel amplitude-integrated electroencephalography alone, and (3) amplitude-integrated electroencephalography plus 2-channel electroencephalography with simultaneous continuous conventional electroencephalography for seizure detection in term infants to check the accuracy of limited channels and compare the different modalities of bedside electroencephalography monitoring.

Methods: Infants referred to a tertiary center with clinical seizures underwent simultaneous continuous conventional electroencephalography and 2-channel (C3-P3 and C4-P4) bedside monitoring. Off-line analysis of the continuous conventional electroencephalographic results was performed independently by 2 neurologists.

Activated memory B cell subsets correlate with disease activity in systemic lupus erythematosus: delineation by expression of CD27, IgD, and CD95.

Objective: Analysis of peripheral B cell subsets in patients with systemic lupus erythematosus (SLE) has provided evidence of specific alterations, such as an expansion of CD27++ plasma cells/blasts and transitional B cells. However, memory B cells in lupus have not been thoroughly investigated, and only recently a CD27- memory B cell subset was identified in the peripheral blood of lupus patients. Focusing on CD27- B cells, this study aimed to identify abnormalities in peripheral B cell subsets in patients with SLE.

Phase behavior of polymer/nanoparticle blends near a substrate.

We use the recent fluids density functional theory of Tripathi and Chapman [Phys. Rev. Lett.

Correlation of cholestasis with serum copper and whole-blood manganese levels in pediatric patients.

Many institutions reduce or eliminate copper (Cu) and manganese (Mn) in parenteral nutrition (PN) solutions when cholestasis develops. Little data exist to support this practice. Fifty-four subjects with known serum Cu, whole-blood Mn, and serum-conjugated bilirubin levels were evaluated in this prospective, observational study.

Polymer chain swelling induced by dispersed nanoparticles.

The dimensions of individual deuterated polystyrene (d-PS) chains in a well-dispersed mixture of protonated polystyrene and chemically identical nanoparticles was determined by neutron scattering. A 10%-20% increase in the radius of gyration of d-PS was found when the nanoparticles are homogeneously dispersed in the polymer, an effect that occurs only when the radius of gyration of the polymer is larger than the nanoparticle radius. These results are reconciled with the existing literature.

Surface-induced first-order transition in athermal polymer-nanoparticle blends.

We investigate the phase behavior of athermal polymer-nanoparticle blends near a substrate. We apply a recent fluids density functional theory of Tripathi and Chapman to a simple model of the blend as a mixture of hard spheres and freely jointed hard chains, near a hard wall. We find that there is a first-order phase transition in which the nanoparticles expel the polymer from the surface to form a monolayer.

Perinatal and early childhood stroke and thrombophilia.

Perinatal and early childhood stroke are relatively frequent occurrences in Western populations compared with a number of more well publicised diseases of childhood. They have devastating consequences for the child and their family. Despite this, little remains known about the aetiology, pathophysiology and outcome of perinatal and childhood stroke.

[Pulmonary leptospirosis].

In this article, the authors discuss briefly the leptospirosis, emphasizing mainly the pulmonary form of disease. The authors review pathology, clinical findings, imaging and broncoscopy diagnosis, treatment of pulmonary leptospirosis. It is also remembered about early clinics and radiology diagnosis to start therapeutics.

Analysis of TaALMT1 traces the transmission of aluminum resistance in cultivated common wheat (Triticum aestivum L.).

Allele diversities of four markers specific to intron three, exon four and promoter regions of the aluminum (Al) resistance gene of wheat (Triticum aestivum L.) TaALMT1 were compared in 179 common wheat cultivars used in international wheat breeding programs. In wheat cultivars released during the last 93 years, six different promoter types were identified on the basis of allele size.

Stroke in children.

Background: Stroke is a major cause of disability and death in children. It can have devastating consequences for families and enormous costs to society. Although considered rare, stroke is more common in children than brain tumours.
