Acute Management of Auricular Hematoma: A Novel Approach and Retrospective Review.


Department of Emergency Medicine, University of Toledo College of Medicine, Toledo, Ohio.


ABSTRACT:: This retrospective case series is used to describe a refined technique for the aspiration and drainage of auricular hematoma that is simple, cost-effective, and allows for rapid recovery. Patients, all high school males participating in competitive wrestling, were enrolled voluntarily after risks and benefits were discussed, and consent was obtained. Criteria for enrollment included acute auricular hematoma of at least 2 cm in size with occurrence no greater than 3 weeks before presentation, and no overt signs of infection. Patients underwent alcohol cleansing followed by injection of 1% lidocaine, and hematoma aspiration with an 18-gauge catheter. The cannula was left within the hematoma cavity, and a compression dressing was applied. This method is an acceptable alternative to current methods of managing auricular hematoma. It is simple, cost-effective, and provides rapid recover with a comparable complication rate than other procedures described.

Effectiveness of Body Wipes as an Adjunct to Reducing Skin Infections in High School Wrestlers.


Primary Care Department, Boynton Health Services, University of Minnesota, Minneapolis, Minnesota.



To compare soap-and-water body wipes and 70% isopropyl alcohol (IPA) body wipes to a CONTROL (no treatment) in reducing skin infections in high school wrestlers competing in weekend tournaments.


Repeated measures study evaluating a soap-and-water body wipe, a 70% IPA body wipe, and no-treatment CONTROL during 2 weekend tournaments.


High school wrestling tournaments in Minneapolis-St Paul and surrounding communities of Minnesota.


Each team was randomly assigned to use either wipe or serve as CONTROL during each tournament.


Presence of skin infections that developed the following week after a weekend tournament.


A total of 151 athletes competed in a total of 474 individual matches. Thirteen athletes tested positive afterward for skin infections. The odds of infection for the tested group compared with the CONTROL group were 0.089 [95% confidence interval (CI), 0.01-0.75; P = 0.026] for the soap-and-water group and 0.44 (95% CI, 0.11-1.69; P = 0.23) for 70% IPA group.


Soap-and-water wipes seem to be more effective in reducing skin infections compared with the no-treatment group.

Is bioelectrical impedance spectroscopy accurate in estimating changes in fat-free mass in judoathletes?


a Exercise and Health Laboratory, Faculty of Human Kinetics, Technical University of Lisbon , Cruz-Quebrada , Portugal.


Abstract Bioelectrical impedance spectroscopy (BIS) provides an affordable and practical assessment of fat-free mass (FFM). However, little information is available on the assessment of changes in fat-free mass in top-level athletes using BIS. The aim of this study was to examine the accuracy of BIS in tracking changes in fat-free mass of elite male judo athletes from a period of weight stability to just before competition, using the four-compartment model (4C model) as reference method. In total, 27 elite male judo athletes (age 22.2 ± 2.8 years) were evaluated. Measures of body volume assessed by air displacement plethysmography, bone mineral content by dual-energy X-ray absorptiometry, and total-body water assessed with deuterium dilution were used in a 4C model. Fat-free mass was also assessed by BIS (FFM(BIS)). Changes in FFM(BIS) were not significantly different from measured by the reference method (P = 0.000). Furthermore, the r (2) was 0.62 and the standard error of the estimate was 1.03 kg. The limits of agreement ranged from -3.36 to 2.59 kg with no bias observed. These findings demonstrate the viability of BIS as a valid tool for tracking fat-free mass in elite male judo athletes. However, based on the wide limits of agreement observed, BIS is less valid at an individual level for tracking fat-free mass in these athletes.

Physiological vs Psychological Evaluation in Taekwondo Elite Athletes.


Department of Human Movement and Sport Sciences, University of Rome "Foro Italico", Rome, Italy.



To anticipate outstanding athletic outcomes the selection process of elite athletes simultaneously considers psycho-physiological and technical parameters. This study aimed to investigate whether Selected and Not Selected athletes for the Italian National taekwondo team could be discriminated by means of sport-specific performances, and psycho-physiological responses to training.


Five established Italian National athletes and 20 elite Italian taekwondo black belt athletes (9 females, 16 males; age: 23.0±3.1yrs; body mass: 67.0±12.1kg) participated in this study. To update the Italian National team roster, the 20 elite athletes participated in a 1-week selection camp (7 training sessions). Selected athletes (n=10) joined Established National athletes during the following 3-week National training period (7 training sessions.week-1). During the 1-week selection camp, differences (p<0.05) between Selected and Not Selected athletes in performances, heart rate responses, blood lactate accumulation [La], subjective ratings of perceived exertion (session-RPE), and mood were examined. During the 3-week national training period, differences (p<0.05) in mood between Selected and Established National athletes were investigated.


With respect to Not Selected athletes, Selected athletes responded better to training in terms of session-RPE (p=0.047), and [La] (p = 0.046). No difference in performance and mood between subgroups emerged. After the 3-week National training period, differences (p=0.035) emerged for confusion, with decreases in the Established National athletes and increases for recently Selected athletes.


Session-RPE and [La] seem to be more effective in discriminating between elite taekwondo athletes than psychological measures. Evaluation of mood could be effective in monitoring the athlete's response to National training.
