Risk factors for cystic fibrosis arthropathy: Data from the German cystic fibrosis registry
2021
Epidemiology and potential risk factors for cystic fibrosis arthropathy (CFA) were studied in a relevant cystic fibrosis (CF) patient cohort.Cohort study of patients included in the German CF registry in 2016-2017. Descriptive analysis, exploratory tests and multivariable logistic regression were used to assess prevalence of CFA and associated potential risk factors for adult patients with/without chronic Pseudomonas aeruginosa infection.6069 CF patients aged from 0 to 78 years were analysed. CFA was observed in 4.9% of the patients. Prevalence was significantly higher in adult patients (8.4%) compared to patients18 years (0.7%; p0.0001). Logistic regression analyses in adult patients (n=33…
Lack of association of Aspergillus colonization with the development of bronchiolitis obliterans syndrome in lung transplant recipients: An internati…
2019
BACKGROUND: Bronchiolitis obliterans syndrome (BOS) is a major limitation in the long-term survival of lung transplant recipients (LTRs). However, the risk factors in the development of BOS remain undetermined. We conducted an international cohort study of LTRs to assess whether Aspergillus colonization with large or small conidia is a risk factor for the development of BOS.METHODS: Consecutive LTRs from January 2005 to December 2008 were evaluated. Rates of BOS and associated risk factors were recorded at 4 years. International Society of Heart and Lung Transplantation criteria were used to define fungal and other infections. A Cox proportional-hazards-model was constructed to assess the a…
Rapid left ventricular filling in untreated hypertensive subjects with or without left ventricular hypertrophy
1992
In this study, independent contribution of age, HR, BMI, casual and ambulatory blood pressure, LVM and LVEF in evaluating diastolic filling have been investigated in 34 never-treated hypertensive patients and in 15 healthy normotensive subjects. All the subjects were free from coronary artery disease, valvular disease, heart failure, renal disease and psychiatric problems. All the hypertensive subjects (never treated) were subgrouped according to presence or absence of LVH. The PFR decreased significantly and tPFR increased significantly in hypertensive patients in comparison with normotensive subjects and they did not change in the presence vs absence of LVH. The PFR was inversely correlat…
Incidence of venous thromboembolism in patients undergoing thoracotomy for lung cancer
2008
Limited information exists on the incidence of symptomatic venous thromboembolism (vTE) in patients undergoing chest surgery for lung cancer. Several factors increase the thromboembolic risk in patients undergoing surgery for lung cancer: the intrinsic procoagulant effect of cancer,extensive surgical intervention, dependent limb position in the operating room, and vessel injury consequent to the operation. Furthermore,these patients might be especially vulnerable to pulmonary embolism (PE) because of the loss of lung tissue and the presence of chronic obstructive pulmonary disease and cardiovascular diseases caused by smoking.t Older studies found a very high incidence of thromboembolic eve…
Analysis of risk factors for neurological dysfunction in patients with acute aortic dissection type A: data from the German Registry for Acute Aortic…
2012
OBJECTIVES: Acute aortic dissection type A (AADA) is associated with major adverse events, such as transient or persistent neurological dysfunction (ND), which may be patient-, disease- or surgery-related. There is a lack of consensus regarding risk factors for ND in AADA patients. The aim of this study was to analyse and identify risk factors for new postoperative ND after aortic repair for AADA. METHODS: Between July 2006 and June 2010, 2137 AADA patients were enrolled in the multi-centre, prospective German Registry of AADA (GERAADA). Perioperative data were prospectively gathered from 50 institutes in Austria, Switzerland and Germany, and multivariate logistic regression analysis was pe…
Hand-assisted laparoscopic living-donor nephrectomy versus open surgery: evaluation of surgical trauma and late graft function in 82 patients
2009
Abstract Objective We evaluated and quantified surgical trauma and late graft function in cases of hand-assisted laparoscopic living-donor nephrectomy (HALLDN) versus open living-donor nephrectom (OLDN). Methods This study is a retrospective nonrandomized single-center analysis. Between 1995 and January 2008, 82 patients with end-stage renal disease received kidney transplantations from living donors. Open living-donor nephrectomy was performed in 37 donors, and 45 underwent laparoscopic hand-assisted nephrectomy. Demographic data and perioperative and postoperative data, such as markers of acute phase (C-reactive protein; serum amyloid A) and biochemical markers of glomerular filtration (s…
Reproducibility of digital image analysis for measuring corneal haze after myopic photorefractive keratectomy.
1997
Purpose To evaluate the usefulness of digital image analysis for quantifying corneal haze by determining the reproducibility of its measurements at the corneal plane. Methods In a prospective study, 20 randomly selected eyes that had undergone myopic photorefractive keratectomy were photographed focusing the slit beam on their anterior corneal surface. Each photograph was examined using computer image analysis techniques that detect the edge of the reticular pattern of the image. Quantification of the difference between two areas, treated and adjacent untreated cornea, each containing 3,750 pixels with a resolution of 256 gray levels, was performed. Intra-analyzer variation was determined b…
Phakic intraocular lenses to correct high myopia
2003
Abstract Purpose: To evaluate the feasibility and safety of using phakic intraocular lenses (IOLs) to correct high myopia by comparing 3 IOL models: Adatomed, Staar, and Artisan. Setting: La Fe University Hospital, Department of Ophthalmology, and the Fundacion Oftalmologica del Mediterraneo, Valencia, Spain. Methods: In this prospective comparative study, a phakic IOL was implanted in 217 highly myopic eyes (118 patients). Fifty-nine eyes received an Adatomed IOL, 21 eyes a Staar IOL, and 137 eyes an Artisan IOL. The mean preoperative spherical equivalent was −15.39 diopters (D) ± 2.83 (SD), −16.00 ± 5.05 D, and −16.17 ± 2.75 D in the Adatomed, Staar, and Artisan groups, respectively. The …
Iris Claw Phakic Intraocular Lens for High Myopia
1997
ABSTRACT BACKGROUND: The implantation of a WorstFechner iris claw intraocular lens (IOL) is one of the surgical procedures used for the correction of high myopia. This technique reduces myopia with stähle refractive results; however, its potential long-term risks have not been evaluated. We report results in 94 eyes with a minimum follow -up of 3 years. METHODS: We studied 94 eyes of 62 patients with myopia 5= -7.00 diopters (D) who underwent Worst-Fechner IOL implantation. Lens decentration, permeability of the blood-aqueous barrier by iris angiography, and changes in corneal endothelial density were analyzed. RESULTS: Mean follow-up time was 48.9 months (range 36 to 72 mo). Three years af…
Long-term results of surgical treatment of high myopia with Worst-Fechner intraocular lenses
1995
Abstract This retrospective study evaluated the results in 90 eyes that had a minus-power anterior chamber intraocular lens implanted to correct high myopia. Preoperative myopia ranged from −7.00 to −24.00 D. Postoperative spherical equivalent was −0.50 D; 80.5% of eyes were within 1.00 D of emmetropia. Two years postoperatively, no cataract formation, retinal detachment, glaucoma, or significant endothelial damage had occurred. We conclude that minus-power lenses can rapidly, safely, and predictably correct high myopia in phakic patients.
