Tolerability and surrogate efficacy parameters of a polymerized depot mixture pollen extracts without dilutional effect.

Aim: To evaluate tolerability of subcutaneous immunotherapy, in a polymerized mixture (Olea europaea/Phleum pratense) depot presentation. Patients & methods: A total of 47 poly-allergic patients received: an abbreviated schedule with three injections at weekly intervals or a cluster schedule with two administrations in 1 day. Both treatments continued with 3 monthly maintenance administrations. Results: Two systemic reactions, (4.3%). One grade 0 and one grade I. No local reactions. Immunoglobulin levels, increased significantly at final visit versus baseline in sIgG and sIgG4; in both schedules and allergens, no significant changes in specific immunoglobulin E levels were detected. Cutaneous reactivity at final visit decreased significantly. Conclusion: Both administration schedules with polymerized mixture of O. europaea/P. pratense, presented an excellent tolerability profile and induced preliminary efficacy changes.

Personal Audiovisual Aptitude Influences the Interaction Between Landscape and Soundscape Appraisal.

It has been established that there is an interaction between audition and vision in the appraisal of our living environment, and that this appraisal is influenced by personal factors. Here, we test the hypothesis that audiovisual aptitude influences appraisal of our sonic and visual environment. To measure audiovisual aptitude, an auditory deviant detection experiment was conducted in an ecologically valid and complex context. This experiment allows us to distinguish between accurate and less accurate listeners. Additionally, it allows to distinguish between participants that are easily visually distracted and those who are not. To do so, two previously conducted laboratory experiments were re-analyzed. The first experiment focuses on self-reported noise annoyance in a living room context, whereas the second experiment focuses on the perceived pleasantness of using outdoor public spaces. In the first experiment, the influence of visibility of vegetation on self-reported noise annoyance was modified by audiovisual aptitude. In the second one, it was found that the overall appraisal of walking across a bridge is influenced by audiovisual aptitude, in particular when a visually intrusive noise barrier is used to reduce highway traffic noise levels. We conclude that audiovisual aptitude may affect the appraisal of the living environment.

Neointimal hyperplasia associated with the use of u-clip.

The U-Clip (Coalescent Surgical, Sunnydale, CA USA) allows the surgeon to create an interrupted anastomosis in the same amount of time that is required for a continuous anastomosis with the elimination of knotting. Its use is indicated especially in minimally invasive surgery. We describe a case of a patient in which the proximal anastomosis was performed by interrupted suture with Coalescent U-Clip anastomotic device. Six months later, he presented with stenosis of the anastomosis, and intravascular ultrasound showed anastomotic neointimal hyperplasia.

A controlled trial of the effects of leg training on breathing pattern and dynamic hyperinflation in severe COPD.

The effects of training on dynamic hyperinflation in stable chronic obstructive pulmonary disease (COPD) were investigated by using a controlled study of 28 subjects with FEV(1) = 42.5 (8.3 SD)%pred and 20 matched controls [FEV(1) = 44.9 (10.4)%pred]. Training consisted of spending 45 min/day, 4 days/week on a cycle-ergometer for six weeks. Maximal inspiratory and expiratory pressures (MIP and MEP), lung volumes, and two constant-work-rate (CWR) exercise tests (low- and high-intensity) were performed. Significant (p < 0.0l) improvements in the training group were observed in MIP [+8 (12) cmH(2)O], MEP [+18 (20) cmH(2)O], and endurance to high-intensity CWR [+7(5) min], and there were significant decreases in respiratory rate and end-expiratory lung volume (EELV) during both exercise tests. At 5 min, EELV decreased 0.1(0.08) L and 0.31(0.13) L and at end of exercise, EELV decreased by 0.09(0.07) L and 0.15(0.11) L respectively, for the moderate- and high-intensity tests. Dyspnea also decreased significantly at both exercise intensities. No changes were observed in the control group. Increased endurance showed independent significant (p < 0.05) correlation with changes in EELV, leg fatigue, and MEP. EELV changes showed a significant negative correlation with resting inspiratory capacity. We conclude that exercise training has beneficial effects on respiratory pattern and dynamic hyperinflation that may partially explain the reduction in dyspnea and the improvement in exercise tolerance.

An unusual travel of an endocardial pacing lead to the left ventricle.

A 80-year-old lady was admitted because of dyspnea, complete AV block and ventricular rate of 15 bpm. A DDDR pacemaker was successfully implanted. Postoperative EKG showed right bundle branch block and X-ray the ventricular lead in the left ventricle. It traveled all the way through a foramen ovale being later relocated in the right apex.
