Extra-intracranial blood shunt mimicking aneurysm rupture: intracranial-pressure-controlled rabbit subarachnoid hemorrhage model

The achieved degree of delayed cerebral vasospasm (DCVS) in the rabbits most frequently applied cistern magna blood injection model is often mild. The aim of this study was to characterize and evaluate the feasibility of an experimental SAH technique that mimics pathophysiological mechanisms and triggers higher degrees of DCVS.

The association between extra-curricular sport participation and social anxiety symptoms in children

Social anxiety is a common psychological complaint that can have a significant and long-term negative impact on a child’s social and cognitive development. In the current study, the relationship between sport participation and social anxiety symptoms was investigated. Swiss primary school children (N = 201), parents, and teachers provided information about the children’s social anxiety symptoms, classroom behavior, and sport involvement. Gender differences were observed on social anxiety scores, where girls tended to report higher social anxiety symptoms, as well as on sport activity, where boys engaged in more sport involvement. MANCOVAs with gender as covariant showed no differences in social anxiety symptoms between children involved in an extracurricular sport and those not engaged in sport participation. Nevertheless, children engaged in team sports displayed fewer physical social anxiety symptoms than children involved in individual sports.

Extra-articular fractures of the proximal phalanges of the fingers: a comparison of 2 methods of functional, conservative treatment

For nonsurgical treatment of fractures of the proximal phalanges of the triphalangeal fingers, different dynamic casts have been described. The main principle behind these casts is advancement and tightening of the extensor hood, caused by a combination of blocking the metacarpophalangeal joints in flexion and actively flexing the proximal interphalangeal joints. In contrast to established treatment protocols using functional forearm casts, the Lucerne cast allows for free mobilization of the wrist joint. The purpose of the current multicenter study was to compare the results of conservative, functional treatment using 2 different methods, either a forearm cast or a Lucerne cast.
