Papillon Lefevre syndrome: bridge between Dermatologist and Dentist

2010

Papillon-Lefevre syndrome is a rare autosomal recessively inherited condition which shows features common to both dentistry and dermatology. This disease is characterized by palmoplantar hyperkeratosis and severe periodon- titis. Therefore both the dentist and the dermatologist should be aware of the same because an early diagnosis of the syndrome can help to preserve the teeth by early institution of treatment, using a multidisciplinary approach. Here we present a case report of Papillon-Lefevre syndrome, along with a comprehensive review of the etiology, pathology, clinical features, differential diagnosis and management of the condition.

Predictors of individual adaptation to high-volume or high-intensity endurance training in recreational endurance runners

2015

The aim of this study was to investigate factors that can predict individual adaptation to high-volume or high-intensity endurance training. After the first 8-week preparation period, 37 recreational endurance runners were matched into the high-volume training group (HVT) and high-intensity training group (HIT). During the next 8-week training period, HVT increased their running training volume and HIT increased training intensity. Endurance performance characteristics, heart rate variability (HRV), and serum hormone concentrations were measured before and after the training periods. While HIT improved peak treadmill running speed (RSpeak ) 3.1 ± 2.8% (P < 0.001), no significant changes occ…

Effect of Streptomycin on Stretch-Induced Change in Myocardial Activation During Ventricular Fibrillation

2008

The aim of this study was to determine whether the changes in myocardial activation pattern resulting from acute stretching during ventricular fibrillation can be counteracted by administering a compound that blocks receptors sensitive to stretch. The study involved 16 isolated rabbit hearts, in which refractoriness and activation frequency during ventricular fibrillation were measured before, during and after localized acute stretching of the left ventricular free wall, either without (series A, n=8) or with (series B, n=8) the presence of streptomycin, 200 micromol. At baseline and during and after stretching, ventricular fibrillation was slower with streptomycin perfusion in series B tha…

Altered atrial restitution dynamics and refractoriness in metabolic syndrome due to up-regulation of potassium repolarizing currents increases suscep…

2021

Abstract Background Metabolic alterations, such as Metabolic Syndrome (MS), describe an association of factors including diabetes, hypertension, obesity and dyslipidemia, linked to higher risk and prevalence of overall cardiovascular disease, arrhythmogenesis and sudden cardiac death. Obese and diabetic patients have shown an increased risk for developing atrial fibrillation (AF). However, underlying mechanisms are not understood. Purpose To study the effects of MS and obesity remodeling in atrial restitution dynamics, frequency-dependent adaptation, refractoriness and its potential susceptibility to AF. Methods Electrophysiological experimental data from High-fat (HF-O, standard rabbit cho…

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…

The history of meniscal-surgery

2000

In comparison with other operative procedures, the history of meniscal-surgery offers some particular differences. Over a long period of time injuries of the semilunar-cartilages of the knee-joint were not generally recognised. In the 18th century only was the clinical picture roughly outlined. There is evidence, that parts of the meniscus were removed much earlier than we have historic proof of. These meniscal fragments were generally mistaken for "loose bodies" in the joints, not knowing the exact etiology. Operative interference with joints was afflicted with a very high incidence of infections and thus complications. Due to this reliable standards of sterility were imperative to obtain …
