Spontaneous fractures of the mandible concept & treatment strategy
2015
Background Spontaneous fractures of the mandible dispose a surgical challenge in comparisons to fractures caused by trauma due to several complicating factors. Additionally: controversies exist concerning the terminology of the field. Material and Methods We conducted a retrospective study of all patients with mandibular fractures, with exclusion of fractures of the coronoid process and the alveolar process, treated at the Department of Oral and Maxillofacial Surgery, Aalborg University Hospital, Denmark between February 2003 and February 2013. Data collected from the medical records included sex, age, cause of fracture, site of fracture, and treatment. Results We identified 517 patients wi…
Prevalence and distribution of odontogenic and nonodontogenic cysts in a Turkish Population
2011
Objective: To determine the relative frequency and distribution of odontogenic and nonodontogenic cysts in a large Turkish population. Study Design A retrospective survey of jaw cysts was undertaken at the Oral Diagnosis and Radiology and Oral and Maxillofacial Surgery Department, Ondokuz Mayıs University Dental School, Samsun, Turkey. Data were retrieved from clinical files, imaging, and histopathology reports from 2000 to 2008; a total of 12,350 patients were included. In each case, we analyzed age, gender, type and number of cysts, and cyst location. Imaging patterns and pathologies associated with cystic lesions were also determined. Results: The prevalence of odontogenic and nonodontog…
Relationship between Patient Discomfort, Appliance Acceptance and Compliance in Orthodontic Therapy
2000
Orthodontic treatment is occasionally a discomfort to patients, due to pain or functional restrictions. In this context, several retrospectively planned studies were performed in the 1980s, but correlations between different aspects of patient discomfort were not investigated. The present study aimed at examining and structuring the psychogenic dimensions of patient discomfort. Furthermore, the impact of the patient's attitude on the intensity of discomfort was to be evaluated in addition to the influences of appliance therapy. The study was performed with 67 patients aged from 9 to 32 years. Prior to insertion of a new appliance, psychogenic scales reflecting their attitude towards orthodo…
The effect of training on aerobic power characteristics of young cross-country skiers.
1987
The influences of growth, training and various training methods were investigated by analysing long-term training effects in young cross-country and biathlon skiers (n = 129). Some athletes (n = 49) were studied six times in three years and some at least once a year during a four year period (n = 48). During three summer training periods skiers emphasized either intensive training or distance training or continued to train normally. The results indicated that maximal oxygen uptake (VO2 max) and heart volume increased between 15 and 20 years of age and the most significant changes in heart volume were observed between 16 and 18 years of age. International level skiers were able to increase t…
Acute hormonal responses to submaximal and maximal heavy resistance and explosive exercises in men and women.
2005
The purpose of this study was to examine acute hormonal and neuromuscular responses in men and women to 3 heavy resistance but clearly different exercise protocols: (a) submaximal heavy resistance exercise (SME), (b) maximal heavy resistance exercise (HRE), and (c) maximal explosive resistance exercise (EE). HRE included 5 sets of 10 repetition maximum (10RM) situps, bench press, and bilateral leg extensions (David 210 machine) with a 2-minute recovery between the sets. In SME, the load was 70%, and in EE, the load was 40% from that used in HRE. A significant increase (p , 0.05) in serum growth hormone (GH) was observed after HRE both in men and women, but the increase was greater (p < 0.05…
Explosive-strength training improves 5-km running time by improving running economy and muscle power
1999
To investigate the effects of simultaneous explosive-strength and endurance training on physical performance characteristics, 10 experimental (E) and 8 control (C) endurance athletes trained for 9 wk. The total training volume was kept the same in both groups, but 32% of training in E and 3% in C was replaced by explosive-type strength training. A 5-km time trial (5K), running economy (RE), maximal 20-m speed ( V 20 m), and 5-jump (5J) tests were measured on a track. Maximal anaerobic (MART) and aerobic treadmill running tests were used to determine maximal velocity in the MART ( V MART) and maximal oxygen uptake (V˙o 2 max). The 5K time, RE, and V MART improved ( P < 0.05) in E, but no…
Neuromuscular characteristics and fatigue in endurance and sprint athletes during a new anaerobic power test
1994
The purpose of this study was to investigate neuromuscular and energy performance characteristics of anaerobic power and capacity and the development of fatigue. Ten endurance and ten sprint athletes performed a new maximal anaerobic running power test (MARP), which consisted ofn x 20-s runs on a treadmill with 100-s recovery between the runs. Blood lactate concentration [la−]b was measured after each run to determine submaximal and maximal indices of anaerobic power (P 3mmol·1 −1,P5mmol·1 −1,P10mmol·1 −1andP max) which was expressed as the oxygen demand of the runs according to the American College of Sports Medicine equation: the oxygen uptake (ml·kg−1·min−1)=0.2·velocity (m·min−1) +0.9·s…
Effects of endurance exercise on serum concentration of calcitonin gene-related peptide (CGRP): A potential link between exercise intensity and heada…
2020
Abstract Background Calcitonin gene-related peptide (CGRP) is a powerful neuropeptide that is strongly involved in headache pain pathogenesis by triggering vasodilation, mast cell degranulation and neurogenic inflammation. This evidence has prompted us to investigate the acute influence of endurance exercise on CGRP concentration in blood. Methods The study population consisted of 48 male amateur runners, who ran a half-marathon distance at 75%–85% of maximal oxygen uptake. Blood was drawn before the run (pre-run) and immediately after each runner ended his trial (post-run). The serum concentration of CGRP was measured with a commercial enzyme-linked immunosorbent assay (ELISA) technique. R…
Estimation of energy consumed by middle-aged recreational marathoners during a marathon using accelerometry-based devices
2020
AbstractAs long-distance races have substantially increased in popularity over the last few years, the improvement of training programs has become a matter of concern to runners, coaches and health professionals. Triaxial accelerometers have been proposed as a one of the most accurate tools to evaluate physical activity during free-living conditions. In this study, eighty-eight recreational marathon runners, aged 30–45 years, completed a marathon wearing a GENEActiv accelerometer on their non-dominant wrist. Energy consumed by each runner during the marathon was estimated based on both running speed and accelerometer output data, by applying the previously established GENEActiv cut-points f…
Skeletal muscle fibre types, enzyme activities and physical performance in young males and females
1978
Differences in skeletal muscle characteristics, metabolic profiles and functional performance between males and females were investigated using young (15--24 yrs) male and female twins as subjects. The comparison included such variables as anthropometry, muscle strength, mechanical power, maximum oxygen uptake, electrical activation of muscle, muscle fibre composition (m. vastus lateralis), and activities of several skeletal muscle enzymes. The results disclosed the following primary differences between males and females: In the various functional tests the performance of females was from 61.1 to 84.6% of that in males; distribution of slow twitch fibres in m. vastus lateralis of the female…
