Severe Chronic Allergic (and Related) Diseases: A Uniform Approach – A MeDALL – GA<sup>2</sup>LEN – ARIA Position Paper

2012

Concepts of disease severity, activity, control and responsiveness to treatment are linked but different. Severity refers to the loss of function of the organs induced by the disease process or to the occurrence of severe acute exacerbations. Severity may vary over time and needs regular follow-up. Control is the degree to which therapy goals are currently met. These concepts have evolved over time for asthma in guidelines, task forces or consensus meetings. The aim of this paper is to generalize the approach of the uniform definition of severe asthma presented to WHO for chronic allergic and associated diseases (rhinitis, chronic rhinosinusitis, chronic urticaria and atopic dermatitis) in …

Abstract Purpose Insufficient and poor sleep patterns are common among adolescents worldwide. Up to now, the evidence on adolescent sleep has been mostly informed by country-specific studies that used different measures and age groups, making direct comparisons difficult. Cross-national data on adolescent sleep that could inform nations and international discussions are lacking. We examined the sleep patterns of adolescents across 24 countries and by gender, age, and affluence groups. Methods We obtained sleep data on 165,793 adolescents (mean age 13.5 years; 50.5% girls) in 24 European and North American countries from the recent cross-sectional Health Behaviour in School-aged Children sur…

Gesundheitsökonomische Bewertung einer antibiotischen Prophylaxe gegenüber postoperativen Endophthalmitiden

2002

BACKGROUND: Two independent epidemiological studies recently suggested the prophylactic relevance of an intraocular antibiosis against endophthalmitis after cataract surgery. The resulting intervention programme, however, has not only ethical drawbacks, but also has a health economical dimension, which will be focussed in this paper. MATERIAL AND METHODS: A cost analysis is performed to compare the direct costs saved by prevention of endophthalmitis cases and the costs generated by the prophylaxis itself. Furthermore, the clinics' indirect costs due to treatment of unprevented endophthalmitis cases are estimated. RESULTS: The overall gain in direct costs turns out to be about 368 000 Euro p…

Gingival recession: prevalence and risk indicators among young greek adults

2014

Objectives: The aim of the current research was to assess the prevalence of gingival recession and to investigate possible associations among this condition, periodontal and epidemiological variables in a sample of young Greek adults in a general dental practice. Material and Methods: A total of 1,430 young adults was examined clinically and interviewed regarding several periodontal and epidemiological variables. Collected data included demographic variables, oral hygiene habits and smoking status. Clinical examination included the recording of dental plaque, supragingival calculus presence, gingival status and buccal gingival recession. Multivariate logistic regression analysis model was p…

Comparison of postoperative pain after root canal treatment using reciprocating instruments based on operator’s experience: A prospective clinical st…

2017

BACKGROUND The aim of the present study was to compare clinically the incidence of postoperative pain after endodontic treatment using the Reciproc System, taking into account the operator's experience. MATERIAL AND METHODS One hundred patients scheduled for routine endodontic treatment were enrolled in this study. Endodontic treatment was carried out in a single visit by undergraduate and postgraduate students. The chemomechanical preparation of root canals was performed with Reciproc instruments. Pretreatment and postoperative pain was recorded using a visual analogue scale (VAS). Postoperative pain and the need for analgesic consumption were assessed at 4, 8, 16, 24, 48 and 72 hours post…

Aktuelle Komplikationsrate der perkutanen transluminalen Koronarangioplastie bei stabiler und unstabiler Angina

2008

During a four-year period (1983-1986) percutaneous transluminal coronary angioplasty (PTCA) was performed on 930 patients with stable or unstable angina with a mortality rate of 0.4%. A transmural myocardial infarct developed in 1.1% and 1.0% of patients required an urgent aorto-coronary bypass. Thus the total rate of severe cardiac complications was 2.5%. Compared with the years 1983-1985, there was in 1986 a significant fall in the number of deaths and of myocardial infarcts from 2.2% to 0.5% (P less than 0.05), while there was a nonsignificant increase in emergency coronary bypass surgery from 0.7 to 1.3%. Patients with unstable angina compared with those with stable angina had a signifi…

Advances in cholesterol-lowering interventions Abstract Numerous epidemiological and prospective studies have shown a direct relationship between total cholesterol and low-density lipoprotein cholesterol (LDL-C) and cardio- vascular disease (cardiovascular morbidity and mortality). In many intervention studies with more than 100,000 subjects, statins have shown a powerful and significant reduction of cardiovascular events and a decrease in cardiovascular and overall mortality, far superior to those produced by any other lipid-lowering group.

Menopause: The Concepts and the Biological Background

2017

The exhaustion of the follicular endowment in the ovary defines the biological basis of menopause. The clinical implications are the loss of menses and fertility. Menopause is preceded by a series of clinical phases, reflected in the Staging of Reproductive Aging Workshop (STRAW). STRAW includes the different reproductive stages, with the clinically impacting menopausal transition and the end of the reproductive life, represented by the late post-menopausal period. Epidemiological studies show that the age at menopause, globally considered at around 50 years, undergoes significant differences across the world regions. High socio-economic conditions may prolong the age at menopause, but othe…
