PURPOSE: The purpose of this study is to surveil the injuries in wrestling according to the different age categories and wrestling styles throughout the competition season. METHODS: The study was designed as a descriptive study. The study was conducted during the wrestling competition season in 2023 (from January 2023 to July 2023), which includes 5 different age categories: U-15, U-17, U-20, U-23, and seniors, along with the Turkey National Wrestling Championships. The data of injuries was recorded immediately after the acute injury was treated by the medical expert during the competitions and evaluated according to the parameters that were obtained. In the statistical analysis, the frequency and percentage values were presented as descriptive statistics and the Chi-square test was used. RESULTS: The study incorporated a total of 6214 wrestlers and a total of 7151 wrestling bouts were performed during these competitions. The analyses indicated that the rate of injury incidence was 42.65‰ in all wrestling styles. When taking account of the injured body parts in all wrestlers' exposures, the occurrence of injuries to the head-face, neck, trunk, upper extremity, and lower extremity, rates of 17.6‰, 1.3‰, 3.6‰, 13.5‰, and 6.6‰, respectively, were observed. According to the pre-diagnosis based on freestyle, Greco-Roman, and female wrestling styles, injuries with bleeding (39.6%, 46.3%, and 14.6%, respectively) and muscle strain (37.9%, 28.7 %, and 52.6%, respectively) most often occurred. CONCLUSION The study findings indicate that most cases of injury appeared to occur in bleeding and muscle strain in all wrestling styles. We suggest that medical experts should set up their health equipment with consideration to the injuries that occur most frequently.

We tried a series of morphological and molecular approaches to identify a new species of Stellantchasmus (Digenea: Heterophyidae) originating from the wrestling half-beaked fish, Dermogenys pusillus of Thailand. Adult worm samples of the new species were recovered from hamsters experimentally infected with the metacercariae from D. pusillus in Thailand. Two isolates (Thai and Korean) of Stellantchasmus falcatus were used as comparative control groups. Worm samples of 3 Stellantchasmus groups were morphologically observed and molecularly analyzed with the mitochondrial cytochrome c oxidase 1 gene. The morphological characteristics of S. dermogenysi n. sp. are similar to S. falcatus originating from brackish water fish, but minor difference was noted including the absence of the prepharynx, position of the ovary near the ceca end, smaller body size, and shorter esophageal length. A phylogenetic tree derived from neighbor-joining and maximum-likelihood methods suggests that S. dermogenysi n. sp. is separated from S. falcatus supported by high bootstrap values. The relative divergences persist between these host-specific trematodes, which we suggest should be recognized as 2 distinct species. Comparisons of S. dermogenysi n. sp. with S. falcatus isolated from mullets in Thailand and Korea indicate a genetic divergence of mitochondrial DNA of 19.4% and 21.7%, respectively. By the present study, a new species, Stellantchasmus dermogenysi n. sp. (Digenea: Heterophyidae), is proposed in Thailand based on molecular evidences, in addition to minor morphological differences between S. falcatus and the new species.

Humerus shaft fracture is a frequent injury in orthopedic practice and generally occurs through direct or indirect trauma. Indirect trauma mechanisms of humerus shaft fractures are mostly related with arm wrestling or throwing activities. Recently, the population enjoying wakeboard are increasing, and the humeral shaft fracture can occur during wakeboarding. We report a case of humerus shaft fracture occurring during wakeboarding trick, which was treated successfully using plate osteosynthesis.

Humeral shaft fracture sustaining arm wrestling is rare, but occurs intermittently. We treated 15 cases of humeral shaft spiral fractures occurred during arm wrestling for fun since 2007. Average age was 22.47±2.69 years, average body mass index was 22.67±2.06 kg/m2. There was no prominent tendency for the fractures to occur at a certain phase of the match. Fractured level and length of each case were measured in the plain radiographs and compared with those of previous reports. Eight cases (53.3%) had an associating medial butterfly fragment, and the time taken until the fracture occurred was longer than that of simple spiral fracture (15.62±9.03 seconds vs. 7.85±2.67 seconds, p=0.048). Fractures were distributed mid to distal one third of humerus, the length of fracture was 7.93±2.69 cm and involved 25.43%±8.24% of humeral length. All cases except one treated surgically using plate and screws and returned their full activities within postoperative 3 months. Although arm wrestling is a simple and joyful sport, participants should be aware of the risks of injury during arm wrestling, especially for the amateur players.

BACKGROUND: Soil is one of the major habitats of fungi. Keratinophilic fungi are an important group of fungi that live in soil, some of which are potential pathogens for humans and animals. OBJECTIVE: The aim of this study was to isolate and identify keratinophilic fungi near Korean wrestling fields, playgrounds, and beauty salons. METHODS: We visited 5 Korean wrestling fields, 15 playgrounds, and 10 beauty salons in Daegu, Korea, from July to August 2015. Soil samples were divided into 3 groups according to the distance from Korean wrestling fields, playgrounds, and beauty salons: near, 10 m, and 100 m. RESULTS: Of 185 soil samples examined, 60 (32.4%) yielded keratinophilic fungi. Specifically, of the 125 samples around Korean wrestling fields and playgrounds, isolation rates were 37.7% (17/45) at the near distance, 27.5% (11/40) at 10 m, and 0% at 100 m. Of the 60 samples around beauty salons, isolation rates were 85% (17/20) at the near distance, 75% (15/20) at 10 m, and 0% at 100 m. Near Korean wrestling fields, playgrounds, and beauty salons, Penicillium spp. were the predominant species (16.9%, 11/65), followed by Fusarium spp. (13.8%, 9/65), Purpureocillium spp. (12.3%, 8/65), Microsporum spp. (6.1%, 4/65), Chrysosporium spp. (3.1%, 2/65), and other species. CONCLUSION: In this study, isolation rates of keratinophilic fungi were higher in the soil closer to the Korean wrestling fields, playgrounds, and beauty salons. Especially near beauty salons, we found keratinophilic fungi in most soil samples. We should be aware of these results and pay attention to eliminate hair or keratins in soils.

Most mediastinal abscesses result from infections after thoracotomy, esophageal perforation or pene- trating chest trauma. This disease is rarely caused by closed blunt chest trauma. All previously reported such cases after closed blunt chest trauma presented with hematoma and sternal osteomyelitis resulting from sternal fracture. Here we report a 15-year-old sumo wrestler who presented with an anterior mediastinal abscess without any mediastinal fracture. The mediastinal abscess resulted from the hematogenous spread of Staphylococcus aureus to a hematoma that might have been caused by a closed blunt chest trauma incurred during sumo wrestling exercises.

The fracture of the humerus during arm wrestling are uncommon, but may occur in the shaft or medial condyle. In the shaft of humerus, the fractures are usually spiral and between the middle and distal third, with or without neurological involvement. A case of a comminuted spiral fracture with butterfly fragment of the distal third of the humerus is reported which had occurred during arm wrestling and was treated by open reduction and internal fixation. The possible mechanism of injury and the question of treatment are discussed.

BACKGROUNDIt is well known that dehydration can impair bodily functions. To evaluate the impact of hydration status under ambient environmental temperature on the immune system, 25 male collegiate wrestlers were recruited to undergo an experimental dehydration program.

METHODSThirteen subjects had controlled diets with individual energy requirements to prevent body mass loss and restricted water intake to cause 4.52% dehydration; they formed the dehydrated group (DE). These subjects developed a urine specific gravity of about 1.030 in 84 hours. Twelve other subjects had no water restriction and maintained their total body weight comprised the euhydrated group (EU). Peripheral blood monocytes (PBMNC) were isolated after dehydration to perform immune response testing by being incubated with a polysaccharide fraction from fu-ling, Poria cocos (polysaccharide fraction from Poria cocos, PCPS, 1 - 30 £g/L), to prepare a conditioned medium termed conditioned medium of PBMNC stimulated by PCPS (PCPS-MNC-CM). More PCPS (25 µg/L) was needed in the DE group to prepare the PCPS-MNC-CM, which was assayed with a growth inhibitory curve for treated U973 cells.

RESULTSThe treated U937 cells, incubated together with PCPS-MNC-CM from the DE group, exhibited a much lower nitroblue tetrazolium (NBT) positive value of (63.7 ± 4.7)%. The concentration of interferon-gamma (IFN-γ), interleukin (IL)-1β and tumor necrosis factor (TNF)-α in PCPS-MNC-CM from subjects after dehydration was much lower than in the CM from the EU group.

CONCLUSIONThe immune response to PCPS in the DE group was lower than in normally hydrated subjects.

The purpose of this study was to do the surveillance study of sports injuries which were suffered to National players of South Korea Team during the summer Asian Games 2010 in Guangzhou. All medical staffs of Korea Delegation were asked to report all sports injuries newly incurred during the Games on injury report form, and the physicians made clinical diagnoses of the injuries. Total 725 injuries (430 athletes) were reported, and 288 injuries (209 athletes) were newly incurred: 68 injuries (58 athletes) were recurrent with previous history, resulting in total incidence rate: 45.5 injuries/1000 athlete exposures (AE) (95% confidence interval [CI]: 40.1-50.6 injuries/1000 AE) and incidence proportion: 26% (95% CI: 23-29). The new injury was highest in athletics (n=37, 12.8%), hockey (n=26, 9.0%), and basketball (n=23, 8.0%). While 162 injuries (56.2%) were incurred during practice, 126 injuries (43.8%) were incurred in competition. The most frequent diagnoses were lateral ankle ligament sprain (n=28, 9.7%, 95% CI: 6.3-13.1), calf muscle cramp (n=23, 95% CI: 4.9-11.1), and hamstring strain (n=22, 95% CI: 4.6-10.7). The relapsed injury was highest in athletics (n=16, 23.5%), basketball (n=6, 8.8%), and wrestling (n=5, 7.4%). While 50 injuries (73.5%) were recurred during practice, 18 injuries (26.5%) were recurred in competition. The most frequent diagnoses of relapsed injury were calf muscle cramp (n=11, 16.2%, 95% CI: 7.4-25.0), low back strain (n=6, 8.8%, 95% CI: 2.1-15.6), and hamstring strain (n=6, 8.8%, 95% CI: 2.1-15.6). Our data indicated incidence rates, incidence proportions, characteristics and frequent diagnoses of acute and recurrent sports injuries during the games, therefore these results could provide relevant information for the sports injury prevention at elite level.
