Endometriosis is a condition that is characterized by the presence of endometrial tissue implants that are outside the uterine lining. It is presented in 10–15% of women in the reproductive age group, 2–5% of postmenopausal women, 25–30% of infertile women and 40–70% of women with chronic pelvic pain. The natural course of endometriosis starts with ectopic tissue implantation and bleeding occur...

We introduce a cross eigenvalue condition matrix for measuring the sensitivity of eigenvalue computations. A fundamental difference between this new object and traditional eigenvalue condition numbers is that cross interactions between eigenvectors that are not associated with the same eigenvalue are taken into account. We develop an abstract formulation that makes it possible to define continu...

The aim of this paper is to propose an adequate condition-based maintenance policy to a gradually deteriorating system using on-line detection algorithms. The originality of this work is due to the fact that the parameters defining the deterioration mode can be unknown. The main purpose is to estimate these unknown parameters in order to propose an adoptive condition based maintenance policy an...

Novelty Detection is an approach to classification that offers advantages over conventional techniques for monitoring high-integrity systems and manufacturing processes: it is not necessary to provide fault data to the system during development. Instead, providing a sufficiently comprehensive model of the system‟s normal behaviour has been formed, deviations from normal working conditions can b...

NEW DRUGS Victoza Is a New Contender In the Diabetes Arena A drug that helps the pancreas make more insulin has been approved. Lira glutide (Victoza, Novo Nordisk), an incretin mimetic, imitates naturally occurring hormones that encourage insulin production after meals. In comparative trials with exenatide (Byetta, Amylin/ Lilly), a twice-daily incretin mimetic already prescribed for initial or...

The aim of this paper is to address the dilemmas of the paediatric surgeon when facing an isolated, unilateral, congenital hydronephrosis and discuss the strategic options for the management of this condition. Congenital hydronephrosis, the most commonly diagnosed uropathy in children, is usually a benign and self-resolving condition. Nonobstructive hydronephrosis does not require operative tre...

Gelastic syncope or laughter-induced syncope is a rare disease often misdiagnosed as narcolepsy or cataplexy. We report a 54-year-old man with syncopal episodes. Each episode started after laughter, leading to light-headedness with blurring of vision and loss of consciousness for a few seconds. The episodes resolved spontaneously. The treatment of gelastic syncope is the same as that for neural...
