广州市2010年登革4型病毒的分离及其E基因进化分析

登革病毒(DEN)E蛋白在病毒与宿主细胞融合和诱导机体产生抗体等过程中发挥重要作用[1].本研究通过对分离株E基因全序列测定,从分子水平确定其型别,并与广州市历年同型DEN流行株及相关国际流行株进行同源性比较,构建系统进化树,追踪其可能输入来源.     

End-stage periventricular leukomalacia: MR evaluation

A prospective study was performed to assess the capabilities of magnetic resonance (MR) imaging in evaluation of end-stage periventricular leukomalacia (PVL) in six children, aged 31-54 months, in whom PVL had been documented by neurologic ultrasonography during the neonatal period. Eight children of similar age (four premature infants and four full-term infants) with normal neurologic development served as controls. A characteristic triad of PVL abnormalities was seen on MR images: (a) abnormally increased periventricular white-matter signal intensity on the first and second echo images of a T2-weighted sequence (repetition time = 2,000-2,400 msec, echo times = 20 or 30 and 80 msec), most commonly observed in the trigone regions of the lateral ventricles bilaterally; (b) marked loss of periventricular white matter in these regions of abnormal signal intensity, predominantly in the periatrial regions; and (c) compensatory focal ventricular enlargement adjacent to regions of abnormal signal intensity. In patients with the classic periatrial distribution of PVL lesions, general correlation between the degree of neurologic impairment and the severity of MR abnormalities was demonstrated. MR imaging was useful in detecting subtle forms of PVL in cases in which neurologic damage was subclinical.     

Infektionsschutzrecht

Background

Legal regulations concerning infection protection have been repeatedly revised in the last few years. At the national level the regulations for notifable diseases were recently broadened to include the suspicion of disease, the disease and death due to mumps, pertussis, rubella including congenital rubella and varicella (chickenpox). In addition notification deadlines were shortened in the new regulations and the information to be reported was expanded. At the “Bundesländer” level, there are also new regulations which expand notification concerning diseases and are extended to other contagious diseases. In addition, infection protection also includes measures to prevent and combat contagious diseases.

Objective

This article describes the current legal situation.
