Effects of in-play cooling during simulated tennis match play in the heat on performance, physiological and perceptual measures
2021
BACKGROUND: The aim of this crossover study was to investigate whether a cooling intervention during simulated tennis match play in the heat could affect players' performance, physiology, perception of effort, and well-being. METHODS: Eight competitive male tennis players performed two testing sessions of 45-minute simulated tennis match play on a hard court at 31.8±2.1°Cand 48.5±9.6% relative humidity. During change-of-end breaks, the cooling interventions (COL) consisted of cold-water ingestion (ad libitum) and an electric fan facing the players at a distance of 1 m combined with an ice-filled damp towel around the neck and on the thighs or no cooling (CON) were applied. Measures of perfo…
Ankle muscle strength influence on muscle activation during dynamic and static ankle training modalities.
2015
Muscle weakness is considered a risk factor for ankle injury. Balance training and barefoot running have been used in an attempt to strengthen the muscles crossing the ankle. It is expected that training tasks that successfully strengthen the ankle would elicit increased muscular activity. However, it is unknown how an individual's ankle strength will influence the muscle activity used during a given task. Twenty-six participants performed dynamic (shod, barefoot running) and static tasks (squat on ground, squat on ®Bosu Ball) believed to strengthen the muscles surrounding the ankle. Electromyographic signals of the tibialis anterior, peroneus longus, gastrocnemius lateralis (GL) and gastro…
Significance of lipopigments with fingerprint profiles in eccrine sweat gland epithelial cells.
1995
Lipopigments with fingerprint profiles in eccrine sweat gland epithelial cells are regular findings in childhood NCL. They have also been described in adult NCL (ANCL) a few times, but not consistently. However, they have been considered nonspecific when not matched by similar abnormal profiles in noneccrine sweat gland epithelial cells. These conflicting reports may pose a diagnostic dilemma as outlined in the following 2 examples. Patient 1 is a 20-year-old man who developed severe tetraparesis and dementia over 2 years. Electroencephalogram was abnormal with epileptiform discharges. The patient died at age 21 years without autopsy ; no other relatives are known to have a similar disease.…
Tuberculosis of the temporomandibular joint.
2013
Summary Introduction Extrapulmonary and extra-spinal tuberculosis (TB) is rare, even in countries where the disease is endemic. Ten percent of these localizations are cervico-facial. Involvement of the temporomandibular joint (TMJ) is very unusual. We present the features of such a case. Review We looked for patients managed for TMJ TB in 2 Maxillofacial Surgery departments and in 1 Pneumology & Phthisiology Department since 1992. The second part of the study was a literature review. One case was found in our departments and 15 other cases were found in published data. Most patients were women with mean age of 39.9 years (5 to 68). Pre-auricular swelling was the predominant functional sign,…
Selective T3–T4 sympathicotomy versus gray ramicotomy on outcome and quality of life in hyperhidrosis patients: a randomized clinical trial
2021
Abstract Background: compensatory hyperhidrosis is the leading cause of patients' dissatisfaction after thoracic sympathicotomy.Objective: to reduce compensatory hyperhidrosis to increase patients' satisfaction. Patients and methods: a prospective randomized study on palmar hyperhidrosis, May 2016-September, 2019. Twenty-one patients T3-T4 sympathicotomy and 21 T3-T4 gray ramicotomy. Data prospectively collected. Analysis at study's end. Focus on the sweating, temperature, quality of life baseline and postoperatively, compensatory hyperhidrosis, hand dryness, patients' satisfaction, and if they would undergo the procedure again and would recommend it.Results: No baseline differences between…
Ki-67 immunoexpression and radiological assessment of necrosis improves accuracy of conventional and modified core biopsy systems in predicting the f…
2021
Based on the French Federation Nationale des Centers de Lutte Contre le Cancer (FNCLCC) grading system, this study assesses the accuracy of conventional and modified core biopsy (CB) systems in predicting the final grade (low vs high) assigned to the resected specimen. Substituting Ki-67 immunoexpression for mitotic count, and radiological for histological assessment of necrosis, we used two modified FNCLCC CB grading systems: (1) Ki-67 immunoexpression alone, and (2) Ki-67 plus radiological assessment of necrosis. We graded 199 soft tissue sarcomas (STS) from nine centers, and compared the results for the conventional (obtained from local histopathology reports) and modified CB systems wit…
Sudomotor testing predicts the presence of neutralizing botulinum A toxin antibodies.
2002
The increasing number of patients being treated with botulinum toxin A complex (BoNT/A) has led to a higher incidence of neutralizing anti-BoNT/A antibodies (ABAs). Because BoNT/A is known to inhibit sweating, here we report sudometry as a possibility for predicting the presence of ABA. Sixteen patients suffering from spasmodic torticollis were selected: in 2 patients, BoNT/A treatment continued to be effective, in 9 patients, the treatment effect was impaired, and in 5 patients, secondary treatment failure developed. BoNT/A (100 mouse units, Dysport; Ipsen Pharma, Berkshire, United Kingdom) was injected subcutaneously into the lateral calves. Sweating was visualized with iodine starch stai…
Cingulo-Insular Structural Alterations Associated with Psychogenic Symptoms, Childhood Abuse and PTSD in Functional Neurological Disorders
2017
Objective Adverse early-life events are predisposing factors for functional neurological disorder (FND) and post-traumatic stress disorder (PTSD). Cingulo-insular regions are implicated in the biology of both conditions and are sites of stress-mediated neuroplasticity. We hypothesised that functional neurological symptoms and the magnitude of childhood abuse would be associated with overlapping anterior cingulate cortex (ACC) and insular volumetric reductions, and that FND and PTSD symptoms would map onto distinct cingulo-insular areas. Methods This within-group voxel-based morphometry study probes volumetric associations with self-report measures of functional neurological symptoms, advers…
Stress and thermoregulation: different sympathetic responses and different effects on experimental pain.
2009
Stress and thermoregulation both activate the sympathetic nervous system (SNS) but might differently affect pain. Studies investigating possible interactions in patients are problematic because of the high prevalence of SNS disturbances in patients. We therefore analyzed the influence of these different sympathetic challenges on experimentally-induced pain in healthy subjects. SNS was activated in two different ways: by mental stress (Stroop task, mental arithmetic task), and by thermoregulatory stimulation using a water-perfused thermal suit (7 degrees C, 32 degrees C, or 50 degrees C). Attentional effects of the mental stress tasks were controlled by using easy control tasks. Both, stress…
Portable PSG for sleep stage monitoring in sports: Assessment of SOMNOwatch plus EEG.
2019
Current sport-scientific studies mostly neglect the assessment of sleep architecture, although the distribution of different sleep stages is considered an essential component influencing an athlete's recovery and performance capabilities. A mobile, self-applied tool like the SOMNOwatch plus EEG might serve as an economical and time-friendly alternative to activity-based devices. However, self-application of SOMNOwatch plus EEG has not been validated against conventional polysomnography (PSG) yet. For evaluation purposes, 25 participants (15 female, 10 male;
