Purpose:
This study aimed to provide the descriptive statistics regarding the injury epidemiology of Korean professional basketball players.
Methods:
In this study, athlete exposures (AEs) and time exposures (TEs) were collected from the 38 basketball players (17 women) who participated in the 2019–2020 regular season. Injury rate (IR) and 95% confidence interval (CI) were calculated.
Results:
A total of 35 injuries were reported. The overall rate of injury was 5.65 per 1,000 AEs and 0.06 per 1,000 TEs. Approximately 65.7% of all the injuries occurred during the official games, with lower limb injuries accounting for about 57.1% of all the injuries. Ankle was the most frequently injured body area (25.7%) with a IR of 1.45 per 1,000 AEs. Sprain accounted for the largest portion with 54.3% overall, followed by strain, contusion and cartilage damage. The most common cause of injuries was contact with another athletes (37.2%), and the recurrence of past injuries (20.0%) also accounted for a high proportion.
Conclusion
Korean professional basketball players experience a high rate of injuries occurring during official games.Ankle sprains were the most common ones. Contact-caused injuries accounted for the highest portion.

A 3-month-old female Maltese puppy was hospitalized with persistent diarrhea in a local veterinary clinic. Blood chemistry and hematology profile were analyzed and fecal smear was examined. Diarrheal stools were examined in a diagnostic laboratory, using multiplex real-time polymerase chain reaction (PCR) against 23 diarrheal pathogens. Sequence analysis was performed using nested PCR amplicon of 18S ribosomal RNA. Coccidian oocysts were identified in the fecal smear. Although multiplex real-time PCR was positive for Cyclospora cayetanensis, the final diagnosis was Cystoisospora ohioensis infection, confirmed by phylogenetic analysis of 18S rRNA. To our knowledge, this the first case report of C. ohioensis in Korea, using microscopic examination and phylogenetic analysis.

Oxidative stress in skin cells can induce the formation of reactive oxygen species (ROS), which are critical for pathogenic processes such as immunosuppression, inflammation, and skin aging. In this study, we confirmed improvements from gamma-irradiated silk sericin (I-sericin) and gamma-irradiated silk fibroin (I-fibroin) to skin cells damaged by oxidative stress. We found that I-sericin and I-fibroin effectively attenuated oxidative stress-induced ROS generation and decreased oxidative stress-induced inflammatory factors COX-2, iNOS, tumor necrosis factor-α, and interleukin-1β compared to the use of non-irradiated sericin or fibroin. I-sericin and Ifibroin effects were balanced by competition with skin regenerative protein factors reacting to oxidative stress. Taken together, our results indicated that, compared to non-irradiated sericin or fibroin, I-sericin, and I-fibroin had anti-oxidation and antiinflammation activity and protective effects against skin cell damage from oxidative stress. Therefore, gamma-irradiation may be useful in the development of cosmetics to maintain skin health.

PURPOSE: Susceptibility vessel sign (SVS) on gradient echo image, which is caused by MR signal loss due to arterial thrombosis, has been reported in acute middle cerebral artery (MCA) infarction. However, the reported sensitivity and diagnostic accuracy of SVS have been variable. Susceptibility-weighted imaging (SWI) is a newly developed MR sequence. Recent studies have found that SWI may be useful in the field of cerebrovascular diseases, especially for detecting the presence of prominent veins, microbleeds and the SVS. The purpose of this study was to evaluate the diagnostic values of SWI for the detection of hyperacute MCA occlusion. MATERIALS AND METHODS: Sixty-nine patients (37 males, 32 females; 46-89 years old [mean, 69.1]) with acute stroke involving the MCA territory underwent MR imaging within 6 hours after the symptom onset. MR examination included T2, FLAIR (fluid-attenuated inversion recovery), DWI, SWI, PWI (perfusion-weighted imaging), contrast-enhanced MR angiography (MRA) and contrast-enhanced T1. Of these patients, 28 patients also underwent digital subtraction angiography (DSA) within 2 hours after MR examination. Presence or absence of SVS on SWI was assessed without knowledge of clinical, DSA and other MR imaging findings. RESULTS: On MRA or DSA, 34 patients (49.3%) showed MCA occlusion. Of these patients, SVS was detected in 30 (88.2%) on SWI. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of SWI were 88.2%, 97.1%, 96.8%, 89.5% and 92.8%, respectively. CONCLUSION: SWI was sensitive, specific and accurate for the detection of hyperacute MCA occlusion.

PURPOSE: Internal mammary lymph node (IMLN) metastasis is an important prognostic indicator in breast cancer. However, the necessity of internal mammary sentinel lymph node biopsy for accurate staging, for choosing adjuvant treatment, and as a prognostic indicator, has remained controversial. METHODS: From January 2001 to December 2006, 525 female breast cancer patients underwent radical surgery after preoperative lymphatic scintigraphy. We retrospectively analyzed the follow-up results, recurrences, and deaths of all patients. RESULTS: There was no significant difference in the clinicopathological characteristics between the axilla and the IMLN groups. The median follow-up period was 118.8 months (range, 7-122 months) in the axilla group and 107.7 months (range, 14-108 months) in the IMLN group. During the median follow-up period, the breast cancer-related death rate in the axilla group was 3.6%, which was not significantly different from that of the IMLN group (1.3%) (p=0.484). The five-year survival rates did not differ between the two groups (p=0.306). The overall recurrence rate and the locoregional recurrence rate also did not differ between the two groups (p=0.835 and p=0.582, respectively). The recurrence rate of IMLN (both ipsilateral and contralateral) metastasis was very low, accounting for 0.5% in the axilla group and 1.3% in the IMLN group (p=0.416). CONCLUSION: The long-term follow-up results showed that there was no significant difference in both overall outcome and regional recurrence between the two groups. Therefore, the requirement for identification of nodal basins outside the axilla or IMLN sentinel biopsy should be reconsidered.

Aortic dissection during pregnancy is a devastating event for both the pregnant woman and the baby. We report a case of acute aortic dissection (Stanford type A) in a pregnant woman with Marfan syndrome at the 29th week of gestation. She underwent a cesarean section followed by an ascending aorta and total arch replacement with cardiopulmonary bypass, without a prior sternotomy. The hemodynamic parameters were kept stable during the cesarean section by using inotropes and vasopressors under transesophageal echocardiography monitoring. The newborn survived after endotracheal intubation and management in a neonatal intensive care unit.

Anesthesia for a patient with a large mediastinal mass is a challenge for anesthesiologists, given the risk of airway collapse and hemodynamic compromise. Moreover, there are very few reports on the anesthetic management of non-intubated video-assisted thoracoscopic surgery (VATS). Thus, in the following case report, we provide an account of the successful anesthetic management and excisional biopsy of a large anterior mediastinal mass (measuring 13 × 10 cm) utilizing non-intubated VATS. The patient was kept awake, maintaining consciousness and spontaneous respiration throughout the procedure, in order to prevent devastating airway collapse and pain control and cough prevention were achieved by thoracic epidural analgesia and lidocaine nebulization.

Occult breast cancer is a type of breast cancer without any symptoms on the breasts or any abnormalities upon radiologic examination such as mammography. In males, there are few cases of breast cancer, the rate of diagnosis of occult breast cancer is very low, and little is known about this disease. We experienced two cases of occult breast cancers manifesting as axillary lymph node metastasis in men. They had a palpable lesion on axillary area several years ago and had not seen a doctor about it. As such there was no abnormality on evaluations for cancer except for axillary lymph node showing signs of carcinoma (primary or metastatic) on biopsy and estrogen receptor-positive and progesterone receptor-positive on immunohistochemistry. The patients were diagnosed with occult breast cancer, and treatments were performed. Herein, we report the rare cases of occult breast cancers in men.
