Omalizumab rapidly improves angioedema-related quality of life in adult patients with chronic spontaneous urticaria: X-ACT study data

2018

Background The X-ACT study aims to examine the effect of omalizumab treatment on quality of life (QoL) in chronic spontaneous urticaria (CSU) patients with angioedema refractory to high doses of H1-antihistamines. Methods In X-ACT, a phase III, double-blind, placebo-controlled study, CSU patients (18–75 years) with ≥4 angioedema episodes during the 6 months before inclusion were randomized (1:1) to receive omalizumab 300 mg or placebo every 4 weeks for 28 weeks. Angioedema-related QoL, skin-related QoL impairment, and psychological well-being were assessed. Results Ninety-one patients were randomized and 68 (omalizumab, n=35; placebo, n=33) completed the 28-week treatment period. At baselin…

Suprachoroidal Bleeding After XEN Gel Implantation

2017

Purpose To report for the first time a clinical case of suprachoroidal bleeding after XEN45 gel implantation. Observations A 84-year old female patient with pseudoexfoliation glaucoma with intraocular pressure (IOP) (20 mm Hg) above target despite maximal IOP-lowering therapy was scheduled for XEN45 gel implantation. The XEN45 gel implantation went without complications and was properly placed in the anterior chamber and beneath the conjunctiva. On the first postoperative day, the patient presented with an IOP of 4 mm Hg, a functioning bleb and a deep anterior chamber. On the second day she developed suprachoroidal bleeding. A wait and see strategy was followed and the patient monitored ste…

Cigarette smoking affects uterine receptiveness

2006

Background Cigarette smoking has long been known to have an effect on female fertility. The existence of an ovarian factor is clear when one considers that the mean age of the menopause is lower and IVF cycle outcome is worse in heavy smokers. The hypothesis of a concomitant uterine effect is raised by indirect evidence from in vitro and in vivo studies, but as yet, no direct evidence has been gained to confirm its existence. In this work, we analyse the association between smoking habit in oocyte recipients and cycle outcome. Methods We have retrospectively analysed the outcome of all oocyte donation cycles performed in our clinic from January 2002 to June 2005 from which there was availab…

Modulational instability in fiber systems with periodic loss compensation and dispersion management

2003

In this paper we study modulational instability in a Kerr fiber taking into account the combined effects of periodic power variations and dispersion management. It is shown that periodic dispersion management and periodic amplification produce nonconventional MI sidebands which are essentially independent of each other. In addition, we show that the amplifier spontaneous emission noise tends to inhibit the growth of sidebands, for a sufficiently long propagation distance.

Experimental demonstration of 160-GHz densely dispersion-managed soliton transmission in a single channel over 896 km of commercial fibers

2003

International audience; We experimentally demonstrate the first 160-GHz densely dispersion-managed soliton transmission in a single channel at 1550 nm over nearly 900 km using commercially available non-zero dispersion-shifted fibers. This performance has been achieved by using a 16 km-long recirculating loop configuration and an appropriate design of the dispersion map.

Distribution of osteonectin mRNA and protein during human embryonic and fetal development.

1992

We investigated the temporal and spatial distribution of osteonectin during human embryonic and fetal development, using in situ hybridization and immunohistochemistry. Osteonectin gene expression was generally found in cells exhibiting high rates of matrix production/proliferation. In mineralized tissue, a strong signal was obtained in osteoblasts, odontoblasts, and chondrocytes of the upper hypertrophic and proliferative zones. Chondrocytes of the mineralized zone showed no expression throughout the different stages of development. Strong osteonectin expression was found in odontoblasts of developing teeth. In addition, osteonectin mRNA and protein were detected in several non-mineralize…

Optimal Response to Cardiac Arrest study: Defibrillation waveform effects

2001

Abstract Introduction: Advances in early defibrillation access, key to the “Chain of Survival”, will depend on innovations in defibrillation waveforms, because of their impact on device size and weight. This study compared standard monophasic waveform automatic external defibrillators (AEDs) to an innovative biphasic waveform AED. Material and methods: Impedance-compensated biphasic truncated exponential (ICBTE) and either monophasic truncated exponential (MTE) or monophasic damped sine (MDS) AEDs were prospectively, randomly assigned by date in four emergency medical services. The study design compared ICBTE with MTE and MDS combined. This subset analysis distinguishes between the two clas…

Parvovirus B19-Associated Microvesicular Eruption

2015

We report on a 3-year-old girl with a microvesicular generalized rash in whom primary infection by parvovirus B19 was demonstrated by seroconversion. To our knowledge, this is the first instance of an eruption arising from parvovirus B19 with this peculiar clinical pattern.
