Cervical Disc Arthroplasty -Efficacy and Indications. Single Center Long-Term Cohort Study Compared to Rcts’ Results
2019
Purpose: This study aims to compare CTDR and ACDF functional outcomes and to determine whether our criterion to exclude patient from the CTDR cohort positively affects the results. Methods: We have conducted a single-center, prospective, observational study of two cohorts: CTDR n=88, and ACDF n=90. The choice of the method for the particular patient was not fully random – it depended on the assumed disqualification criterion for CTDR the lack of intra-operatively determined mobility. Both cohorts were clinically followed over the long-term (average: 8 years). Our results were summarized with the results of large randomized studies subjected by our team to a meta-analysis reported in full in…
Tobacco use in lung cancer (LC) patients (p) in Spain
2019
Abstract Background Tobacco use, mainly as cigarette smoking, is the leading cause of lung cancer. Eighty-five percent of LC occur in smokers. Understanding the Spanish smoking habits allows the government to design health care policies against this consumption. To do so, the Grupo Espanol de Cancer de Pulmon (Spanish Lung Cancer Group) made this analysis within the context of the Thoracic Tumor Registry (TTR). Methods The TTR is an observational cohort multicenter study in Spain. The study is conducted according to the Declaration of Helsinki and approved by the institutional review board of each participating site. The registry was approved by the Spanish Drug Agency, as a non-post-author…
Efficacy of subcutaneous and sublingual immunotherapy with grass allergens for seasonal allergic rhinitis: a meta-analysis–based comparison
2012
Background: Subcutaneous (SCIT) and sublingual (SLIT) immunotherapy are the 2 most prescribed routes for administering allergen-specific immunotherapy. They were shown to be effective in control of symptoms and in reducing rescue medication use in patients with allergic diseases, but their effectiveness has to be balanced against side effects. In recent years, SLIT has been increasingly prescribed, instead of SCIT, because of improved safety and easy administration. Objective: We assessed which route is the most effective in the treatment of patients with seasonal allergic rhinitis to grass pollen. Methods: An indirect meta-analysis–based comparison between SCIT and SLIT was performed. Trea…
Endoscopic Sinus Surgery Associated with Rhinoseptoplasty: A Case-control Study
2018
Objective: To examine the difference between outcomes in the administration of concurrent endoscopic sinus surgery (ESS), septoplasty (SP), and rhinoplasty (RP) and concurrent ESS and SP in 1 single surgical session. Methods: Patients who underwent concurrent ESS and SP from September 2004 to July 2015 were identified. Furthermore, patients among them who underwent functional primary RP were selected. Subjects who had been administered concurrent ESS, SP, and RP (primary RP) were matched for sex, age, sinonasal surgical procedures for treatment of chronic rhinosinusitis with patients underwent concurrent ESS and SP, used as control subjects. A literature review was performed to find previou…
1043 Evaluation of Pediatric Testes After Surgery by Laser Doppler and White Light Spectroscopy
2012
Aim To evaluate testes after unilateral orchiopexy Laser Doppler and white light spectroscopy and compare microcirculation with contralaterat testis and healthy controls. Methods A combination of the laser Doppler (determination of blood flow) and white light spectroscopy (determination of oxygen saturation and hemoglobin amount) is used to determine microcirculation at two different depth levels non-invasively. Patients were recruited after unilateral orchiopexy. Controls were age-matched boys without relevant disease. Ethical approval was obtained. Results 99 patients were included after unilateral orchiopexy at the age of 3.5 years (+-2.9 years). 65% underwent surgery after their second …
Our Assessment Using Palate Postoperative Problems Score (PPOPS): Tool for the Evaluation of Results in Palatal Surgery Techniques
2018
Obstructive sleep apnoea syndrome is a chronic condition characterized by frequent episodes of collapse of upper airways during sleep. Prevalence of the disease is settled at about 3–7%. Today, palatal surgery is a reference point in OSAHS treatment and there are many different surgical techniques. The purpose of our work is to compare post-operative results of palate surgery techniques used in our practice in OSAHS patients, studying the degree of patients’ satisfaction with a recent score recommended by Rashwan et al. called PPOPS (Palate Post-Operative Problems Score). A retrospective study was performed on a sample of 40 patients subject to different palate surgery techniques for OSAS. …
A clinical study of the effect of calcium sodium phosphosilicate on dentin hypersensitivity
2012
Objective: Dentinal hypersensitivity is a commonly encountered problem with varied treatment options for its management. A large number of home use products have been tested and used for the management of dentinal hypersensitivity. This 8 week clinical trial investigates the temporal efficacy of commercially available calcium sodium phosphosilicate containing toothpaste in comparison to a potassium nitrate containing toothpaste. Methods: A total 20 subjects between the ages of 18 to 65 years were screened for a visual analogue score (VAS) for sensitivity of 5 or more by testing with a cold stimulus and randomly divided into test and positive control groups. Baseline sensitivity VAS scores t…
Ramadan Observance during Pregnancy in Germany: a Challenge for Prenatal Care.
2018
Abstract Introduction Fasting during Ramadan while pregnant has been shown to have long-term negative effects on the offspringʼs physical and cognitive health. Even though most Muslims do not believe pregnant women are obligated to fast during Ramadan, fasting rates of up to 87% have been reported for pregnant women. No data exists to date about Ramadan adherence and behavior in Germany. Methods The Mainz Study of Ramadan and Pregnancy surveyed pregnant Muslims and new Muslim mothers in Mainz between October 2016 and January 2017 and collected information on Ramadan adherence and behavior. We also collected data on personal characteristics and opinions, to identify determinants of fasting u…
Validity of automated refraction after segmented refractive multifocal intraocular lens implantation
2017
Aim To evaluate the clinical utility of automated refraction (AR) and keratometry (KR) compared with subjective or manifest refraction (MR) after cataract or refractive lens exchange surgery with implantation of Lentis Mplus X (Oculentis GmbH) refractive multifocal intraocular lens (IOL). Methods Eighty-six eyes implanted with the Lentis Mplus X multifocal IOL were included. MR was performed in all patients followed by three consecutive AR measurements using the Topcon KR-8000 autorefractor. Assessment of repeatability of consecutive AR before and after dilation with phenylephrine 10%, and comparison of the AR and KR with MR using vector analysis were performed at 3mo follow-up. Results Ana…
Intradiverticular Ampulla of Vater: Personal Experience at ERCP
2013
Introduction. Conflicting results have been reported about the true impact of intradiverticula ampulla (IA) on the technical success and complication rate of endoscopic retrograde cholangiopancreatography (ERCP). Patients. A total of 500 patients who underwent ERCP were divided into two groups according to the presence (group A, 81 patients) or absence (group B, 419 patients) of IA. Success rate, difficulty at cannulation, findings at ERCP, and procedure-related complications were retrospectively reviewed. Results. Successful cannulation was achieved in 100% of group A patients compared to 98% of group B patients (P = ns). There was a significant difference in the type of cannulation that w…
