Risk factors for gastroenteritis associated with canal swimming in two cities in the Netherlands during the summer of 2015: A prospective study

2017

Urban canal swimming events are popular in the Netherlands. In 2015, two city canal swimming events took place, in Utrecht (Utrecht Singel Swim, USS) and in Amsterdam (Amsterdam City Swim, ACS). This prospective study characterizes the health risks associated with swimming in urban waters. Online questionnaires were sent to 160 (USS) and 2,692 (ACS) participants, with relatives of participants who did not swim completing the questionnaire as a control. Swimming water specimens and stool specimens of diarrheic participants in the ACS group were analysed. A total of 49% of USS and 51% of ACS swimmers returned their questionnaires. Nine percent of USS swimmers and 4% of non-swimmers reported g…

Comparison of dental treatment performed under general anesthesia between healthy children and children with special health care needs in a hospital …

2018

Background The aim of this retrospective study was to assess and compare the dental treatments performed under general anesthesia (GA) between healthy children and children with special health care needs (SHCN) according to age group and gender at king Fahd hospital, Dhahran, Saudi Arabia. Material and Methods Data was retrieved from the records of 304 healthy and SHCN children 1 18 years of age who received dental rehabilitation under GA in the period 2015-2018. The dental treatment modalities were compared in the two groups and differences according to age group and gender were reported. Results Compared to healthy children, children with SHCN received significantly less pulp therapy trea…

One-year implant survival following lateral window sinus augmentation using plasma rich in growth factors (PRGF) : a retrospective study

2019

Background The aim of this study was to assess one-year implant survival after lateral window sinus augmentation using PRGF combined with various bone grafting materials. Material and Methods This was a retrospective chart review and radiographic analysis of patients that had undergone lateral window sinus augmentation with PRGF and had dental implants placed at least 6 months post augmentation. All implants included were followed up for at least one year after placement. Demographic, sinus and implant related characteristics (residual ridge height, sinus membrane perforation, type of graft material, implant length and width and ISQ at placement) were analyzed. Results A total of 31 patient…

Paget's disease of scrotum and penis case report of a re-irradiation and review of the literature.

2020

Extramammary Paget's disease (EMPD) is a rare cutaneous adenocarcinoma generally arising in the anogenital region. Surgery is still considered the treatment of choice for patients with EMPD, while Radiotherapy is a common alternative for inoperable cases and it's necessary in case of lack of surgical radicality. In this article, we described our experience and a review of the literature, with a particular focus on radiation-induced toxicity and on the feasibility of re-irradiation. A 70-year-old patient with EPMD underwent adjuvant radiotherapy in 2015. After 28 months for recurrence another radiant treatment was performed. No G3 (CTCAE v4) toxicity were recorded. In the last follow-up visi…

Refraktiver Nutzen und inkrementelle Kosten der LASIK: Ergebnisse einer Kosten-Nutzen-Studie an zwei universitären LASIK-Zentren

2003

BACKGROUND No data is available to date on the cost effectiveness of laser in situ keratomileusis (LASIK) with regard to the German-speaking health care system. Hence we compared the clinical outcome and cost data of two German LASIK centres in respect of procedure cost effectiveness from the patient perspective. MATERIAL AND METHODS A retrospective cohort study was implemented at the University Hospitals of Mainz and Mannheim. Data on refractive outcome were obtained from the LASIK centres' patient documentation, cost data on the surgery as well as on eyeglasses etc. before and after the surgery were obtained from patient interviews. The primary endpoint of this investigation was the indiv…

Portal Vein Thrombosis Relevance on Liver Cirrhosis: Italian Venous Thrombotic Events Registry

2016

Portal vein thrombosis may occur in cirrhosis; nevertheless, its prevalence, and predictors are still elusive. To investigate this issue, the Italian Society of Internal Medicine undertook the “Portal vein thrombosis Relevance On Liver cirrhosis: Italian Venous thrombotic Events Registry” (PRO-LIVER). This prospective multicenter study includes consecutive cirrhotic patients undergoing Doppler ultrasound examination of the portal area to evaluate the prevalence and incidence of portal vein thrombosis over a 2-year scheduled follow-up. Seven hundred and fifty-three (68 % men; 64 ± 12 years) patients were included in the present analysis. Fifty percent of the cases were cirrhotic outpatients.…

Pegylated interferon α plus ribavirin for the treatment of chronic hepatitis C: A multicentre independent study supported by the Italian Drug Agency

2014

a b s t r a c t Background: Data on the efficacy of Peg-interferon/ribavirin therapy for chronic hepatitis C are mostly derived from treatment of selected patients enrolled in clinical trials. This study aimed to assess the effectiveness of Peg-interferon/ribavirin therapy in “real world” chronic hepatitis C patients in Italy. Methods: Independent observational multicentre study including consecutive patients receiving Peginterferon/ribavirin in the 18 months before (retrospective phase) and after (prospective phase) the start of the study. Results: 4176 patients were eligible. The final study population consisted of 2051 patients in the retrospective and 2073 in the prospective phase. Sust…

Frequency of Left Ventricular Hypertrophy in Non-Valvular Atrial Fibrillation

2015

Left ventricular hypertrophy (LVH) is significantly related to adverse clinical outcomes in patients at high risk of cardiovascular events. In patients with atrial fibrillation (AF), data on LVH, that is, prevalence and determinants, are inconsistent mainly because of different definitions and heterogeneity of study populations. We determined echocardiographic-based LVH prevalence and clinical factors independently associated with its development in a prospective cohort of patients with non-valvular (NV) AF. From the "Atrial Fibrillation Registry for Ankle-brachial Index Prevalence Assessment: Collaborative Italian Study" (ARAPACIS) population, 1,184 patients with NVAF (mean age 72 ± 11 yea…

Joint use of cardio-embolic and bleeding risk scores in elderly patients with atrial fibrillation

2013

Background Scores for cardio-embolic and bleeding risk in patients with atrial fibrillation are described in the literature. However, it is not clear how they co-classify elderly patients with multimorbidity, nor whether and how they affect the physician's decision on thromboprophylaxis. Methods Four scores for cardio-embolic and bleeding risks were retrospectively calculated for ≥ 65 year old patients with atrial fibrillation enrolled in the REPOSI registry. The co-classification of patients according to risk categories based on different score combinations was described and the relationship between risk categories tested. The association between the antithrombotic therapy received and t…
