Simulations show a direct correlation between the void nucleation stress and the ability of a grain boundary to plastically deform by emitting dislocations, during shock compression. Plastic response of a GB, affects the development

of stress concentrations believed to be responsible for void nucleation by acting as a dissipation mechanism for the applied stress.”
“In this article, the anatomical and morphological features of the acetabulum in infancy and childhood are presented. The pathology and treatment of older children and adolescents is deliberately not covered, because the fracture morphology and treatment see more of patients aged 13 to 15 years is based on the criteria of adult medicine. Especially in the younger child, the anatomical differences are of particular importance. The younger the child is, the more

difficult the diagnosis. Therefore today, MRI examinations should be generous used, even if anesthesia is necessary. If the injured child is hemodynamic stable, anesthesia can be electively used for a more complex diagnosis. Acetabular fractures are particularly problematic in infancy because even with optimal treatment and perfect reduction growth disturbances can occur. These manifest as so-called secondary dysplasia. During treatment, care should be taken to click here ensure that a surgical team having experience with the infant and juvenile skeleton is available and that appropriate implants are available.”
“Aims: Studies in adults have identified evidence of

inherited cardiovascular diseases in up to 53% of families, but data on the prevalence of familial disease in children are scarce. The aim of this study was to evaluate the yield of clinical screening in pediatric first-degree relatives of victims of SADS using a systematic and comprehensive protocol. Methods: Patients referred for family screening after sudden cardiac death (SCD) of a family member were, retrospectively, enrolled into the study. Systematic evaluation of the children included SBC-115076 molecular weight clinical examination, family history, electrocardiogram (ECG), echocardiogram, 24-hour tape, and signal-averaged ECG. Older patients also underwent exercise testing, cardiac magnetic resonance imaging, and ajmaline provocation testing. Results: A total of 90 children from 52 consecutive families were included in the study. An inherited cardiac disease was identified in seven first-degree children from seven (13.5%) families (five children were diagnosed with Brugada syndrome, one with long QT syndrome, and one with catecholaminergic polymorphic ventricular tachycardia). Two further children had late potentials on signal-averaged ECGs with no other abnormalities. Conclusions: These data show a high prevalence of inherited heart disease in pediatric first-degree relatives of SADS victims.
