First-line cisplatin with docetaxel or vinorelbine in patients with advanced non-small-cell lung cancer: A quality of life directed phase II randomiz…
2009
Abstract Background Quality of life (QoL) has gained greater importance in the management of metastatic non-small-cell lung cancer due to the palliative nature of treatment. Docetaxel (DCT) and cisplatin (CDDP) doublet has been reported to be associated to a better QoL than the weekly vinorelbine (VNR) and CDDP regimen. Recently a newer more tolerated schedule of the VNR/CDDP regimen has been published and is widely employed in medical practice. The impact of these regimens on patients' QoL as well as symptoms control and type and grading chemo-related side-effects has been compared prospectically. Methods Patients received CDDP 75mg/m 2 plus DCT 75mg/m 2 on day 1 every weeks (arm A) or CDD…
Effect of Salmeterol on Seasonal Changes in Airway Responsiveness and Exhaled Nitric Oxide in Pollen-Sensitive Asthmatic Subjects
2002
Objective Using a model of natural allergen exposure, we examined the effect of regular treatment with salmeterol on allergen-induced changes in airway responsiveness and exhaled nitric oxide (ENO). Design Double-blind, randomized, parallel-group study. Setting Specialist allergy unit in a university hospital. Patients Asthmatic patients sensitized to pollen allergens were randomly allocated to monotherapy with salmeterol (n = 14) or placebo (n = 13). Interventions Salmeterol, 25 μg, and placebo inhalers, two puffs bid, for 6 weeks. Measurements Spirometry, the level of a provocative concentration of a substance (methacholine) causing a 20% fall in FEV 1 (PC 20 ), the PC 20 level for adenos…
Is it possible to predict which patients with mild pneumonias will develop hypoxemia?
2009
SummaryUsually, mortality due to mild community-acquired pneumonias (CAP) (Pneumonia severity index (PSI) classes I–III) is low (<3%), but the appearance of hypoxemia significantly increases mortality. Our aim was to determine the clinical parameters associated with risk factors of developing hypoxemia in subjects with mild CAP (PSI I–III) and the clinical outcomes of the hypoxemic group.We analyzed clinical characteristics and the outcomes of patients with mild CAP and hypoxemia (PaO2/FiO2<300), in a prospective, multicenter cohort study of 1195 patients.Mild pneumonias (PSI I–III) were found in 645 cases (53.9%), of which 217 (33.6%) presented hypoxemia according to a PaO2/FiO2<300. Patie…
Disturbed motor control of rhythmic movement at 2 h and delayed after maximal eccentric actions.
2008
The aim of this study was to examine the influence of exercise-induced muscle damage on elbow rhythmic movement (RM) performance and neural activity pattern and to investigate whether this influence is joint angle specific. Ten males performed an exercise of 50 maximal eccentric elbow flexions in isokinetic machine with duty cycle of 1:15. Maximal dynamic and isometric force tests (90 degrees , 110 degrees and 130 degrees elbow angle) and both active and passive stretch reflex tests of elbow flexors were applied to the elbow joint. The intentional RM was performed in the horizontal plane at elbow angles; 60-120 degrees (SA-RM), 80-140 degrees (MA-RM) and 100-160 degrees (LA-RM). All measure…
The Penile Plication Procedure: An Alternative Method for Straightening Penile Deviation
1991
AbstractThe number of reported cases of congenital and acquired penile deviation is evidently increasing. We describe our experience with the penile plication procedure, which we used to treat 40 patients with penile deviation. Postoperatively, all patients regained the ability for sexual intercourse, with potency remaining unimpaired. Of the patients 96% were completely satisfied with the result of the operation. Sustained complications have not been observed. To avoid major trauma the surgical intervention should not include removal of ellipsoids from the penile tunica albuginea as proposed by Nesbit. Since the penile plication method produces equally good results in terms of performance …
Complex radial head and neck fractures treated with modern locking plate fixation
2019
Background Internal fixation of complex radial head and neck (CRHN) fractures is difficult, and postoperative complications are common. This study evaluated elbow function and patient clinical status after internal fixation of CRHN fractures with modern locking plates. Methods We included 40 patients with 41 fractures (1 bilateral lesion). In 25 patients (61%), a concomitant injury was found. Patients were an average age of 46 years (range, 22-70 years). The mean follow-up time was 36 months (range, 2-70 months). Postoperative assessments included evaluation of range of motion, functional scores, and radiologic findings. We assessed fracture healing, surgical complications, revision surgery…
Flicker Defined Form Perimetry in Glaucoma Suspects with Normal Achromatic Visual Fields
2014
To evaluate if repeated flicker-defined form (FDF) perimetry can detect visual field (VF) defects in glaucoma suspects with normal findings in achromatic standard automated perimetry (SAP).Patients with optic nerve heads (ONHs) or retinal nerve fiber layer (RNFL) findings clinically suspicious for glaucoma and normal SAP were enrolled. Patients underwent VF testing with FDF perimetry (Heidelberg Edge Perimetry, HEP) at two consecutive visits (HEP I and HEP II) and confocal scanning laser ophthalmoscopy with the Heidelberg Retina Tomograph (HRT). Abnormal HEP was defined by cluster-point analysis (CPA) and by the HEP specific glaucoma hemi-field test (GHT). Results were compared with an age-…
Plasma homocysteine levels are associated with ulceration of the foot in patients with type 2 diabetes mellitus.
2010
Background To examine the association of biochemical markers of risk (plasma Hcy, microalbuminuria, lipoprotein (a)(Lp(a)) and diabetic dyslipidaemia) with the prevalence of diabetic foot ulceration in type 2 diabetic patients. Methods Case/control study conducted in 198 type 2 diabetic patients. 89 patients have foot ulcers and 109 have no foot ulcers (control group), in order to establish ORs for diabetic foot ulceration. In all subjects plasma Hcy, Lp(a), total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, apolipoprotein B, HbA1c and microalbuminuria were measured using standard procedures. Results Plasma Hcy, microalbuminuria, HbA…
Blockade of interleukin 6 trans signaling suppresses T-cell resistance against apoptosis in chronic intestinal inflammation: Evidence in Crohn diseas…
2000
The pro-inflammatory cytokine interleukin (IL)-6 (refs. 1-5) can bind to cells lacking the IL-6 receptor (IL-6R) when it forms a complex with the soluble IL-6R (sIL-6R) (trans signaling). Here, we have assessed the contribution of this system to the increased resistance of mucosal T cells against apoptosis in Crohn disease (CD), a chronic inflammatory disease of the gastrointestinal tract. A neutralizing antibody against IL-6R suppressed established experimental colitis in various animal models of CD mediated by type 1 T-helper cells, by inducing apoptosis of lamina propria T cells. Similarly, specific neutralization of sIL-6R in vivo by a newly designed gp130-Fc fusion protein caused suppr…
Synovial fluid-derivedYersinia-reactive T cells responding to human 65-kDa heat-shock protein and heat-stressed antigen-presenting cells
1991
Humoral and cellular immune reactions to heat-shock proteins have been implicated in the pathogenesis of arthritis. Heat-shock proteins occur in bacteria as well as all eukaryotes and have been highly conserved during evolution. Cross-reactivity between bacterial and human heat-shock proteins induced at the site of inflammation may underlie the pathogenesis of some forms of arthritis. In order to test this hypothesis, we raised and cloned a Yersinia-specific T cell line from the synovial fluid lymphocytes of a patient with Yersinia-induced reactive arthritis. From this line we obtained a CD4+ T cell clone that proliferated in response to Yersinia antigens and both to the mycobacterial and t…
