INTRODUCTION Computer vision syndrome (CVS) is a condition in which a person experiences one or more of eye symptoms as a result of prolonged working on a computer. OBJECTIVES To determine the prevalence of CVS symptoms, knowledge and practices of computer use in students studying in different universities in Malaysia, and to evaluate the association of various factors in computer use with th...

PURPOSE Amniocentesis (AC) and chorionic villus sampling (CVS) play an important role in the diagnosis of genetic anomalies. The aim of this study was to evaluate presentable numbers of procedure-related complications of genetic interventions in a tertiary referral hospital. MATERIALS AND METHODS The pregnancy outcome of women who underwent genetic AC or CVS during 2003-2010 at the Department...

In the past few years considerable attention has been given to a relatively new method of prenatal diagnosis known as chorionic villus sampling (CVS). Because CVS can be performed in the first trimester it is hailed by many as a significant advance over amniocentesis. What has not been as publicized, however, are the disadvantages of CVS and earlier prenatal diagnosis. The emotional costs of CV...

We show that minimum connected (s, t)-vertex separator ((s, t)-CVS) is Ω(log2− n)-hard for any > 0 unless NP has quasi-polynomial Las-Vegas algorithms. i.e., for any > 0 and for some δ > 0, (s, t)-CVS is unlikely to have δ.log2− n-approximation algorithm. We show that (s, t)-CVS is NPcomplete on graphs with chordality at least 5 and present a polynomial-time algorithm for (s, t)-CVS on bipartit...

The hypothalamic-pituitary-adrenal (HPA) axis is the primary endocrine system to respond to stress. The HPA axis may be affected by increased level of corticotrophin-releasing factors under chronic stress and by chronic administration of monosodium glutamate (MSG). The purpose of this study was to investigate whether chronic MSG administration aggravates chronic variable stress (CVS)-induced be...

BACKGROUND This study was designed to evaluate emergency physician success and satisfaction using a video-assisted semi-rigid fiberoptic stylet, the Clarus Video System (CVS), during a simulated difficult airway scenario. FINDINGS Emergency physicians (EPs) of all levels were first shown a brief slide show and three example videos, and then given 20 min to practice intubating a mannequin usin...

Cataclysmic variables (CVs) are tracers of dynamical evolution in globular clusters. A significant sample has been found by the relatively shallow Hα surveys conducted with HST thus far in just three globulars: NGC 6397 (3), NGC 6752 (2), and ω-Cen (2). These are identified with the low luminosity x-ray sources discovered in these globulars with similarly moderate-depth ROSAT surveys. Follow-up...

The cannabinoid hyperemesis syndrome (CHS) and the cyclic vomiting syndrome in adults (CVS) are both characterized by recurrent episodes of heavy nausea, vomiting and frequently abdominal pain. Both syndromes are barely known among physicians. Literature is inconsistent concerning clinical features which enable differentiation between CVS and CHS. We performed a literature review using the LIVI...
