OBJECTIVE: Korea (ranked 16th) and Japan (ranked 13th) show similar rankings, skills, and performance in basketball. However, the countries differ in size and the number of players in the national women's basketball system. The current study aimed to compare the psychological factors (anxiety, and temperament and character) and the national teams' players' characteristics between 80 Korean (WKBL players) and 76 Japanese (WJBL players) female basketball players in six professional teams each. METHODS: All players were asked to complete demographic characteristics including age, career years, position, number of past and presents positions, and clinical scales, including sports anxiety, state anxiety, trait anxiety, and the Temperament and Character Inventory (TCI). Hierarchical logistic regression analyses among individual factors, physical factors, basketball status, anxiety factors, and temperamental conditions were conducted. RESULTS: In all basketball players, all five models were significantly associated with national team players. The TCI factors were the strongest predictive factors for Korean national team players, while the anxiety factors were the strongest predictive factors for Japanese national team players. WKBL players in all positions showed higher sports anxiety and harm avoidance than WJBL players. WJBL players scored higher on self-directedness and cooperativeness than WKBL players. CONCLUSION: For predicting national team players, temperament and character were crucial factors in WKBL players where anxiety was the most important one for WJBL players.

The purpose of this review was to investigate the relationship between aerobic exercise and cognitive function as well as synthesize the effect of aerobic exercise intervention studies centered on psychiatric symptoms associated with general cognitive deficit. Prospective studies on aerobic exercise and improvement of cognitive function were reviewed and synthesized. In addition, this literature review provides significant positive results on the relationship between aerobic exercise and general cognitive deficit associated with psychiatric symptoms. Review of this literature suggests that there is a positive relationship between participation in aerobic exercise and cognitive function. In this text, there are at least three general pathways by which aerobic exercise may facilitate executive function in children : 1) cognitive demands inherent in engaging in physical activity, 2) cognitive demands inherent in cooperation of complex motor tasks, and 3) physiological changes resulting from aerobic exercise. Another main finding of this review is that physical activity has a stronger influence on cognitive deficit, including attention-deficit hyperactivity disorder, depression, and anxiety. Development of cognitive function is the most important factor for children and youth. Therefore, future research should prove relationship between physical activity and cognitive function using a more scientific and quantitative approach design.

Carcinosarcoma is a rare malignant tumor composed of a mixture of neoplastic epithelial and mesenchymal elements, which has been reported in many organ systems, but its occurrence is very rare in the skin. An 81-year-old female patient presented with aml-year-history of a painful exophytic mass on the tip of the middle finger of the right hand involving the distal part of the nail bed. The mass was 1 × 1 × 0.6 cm in size, hard, flesh colored, ulcerated and easily bleeding. Microscopically, the epidermis at the margin of the tumor showed the characteristic findings of squamous cell carcinoma and the carcinomatous component was mixed with malignant mesenchymal components focally differentiating into chondrosarcoma. This combination of squamous cell carcinoma and chondrosarcoma has not been reported yet in the skin. She had a distal interphalanx amputation and no recurrence appeared for 1 year on follow-up.

We report a rare case of subepithelial hematoma of the renal pelvis (AntopoI-Goldman Lesion). A 55-year-old women visited our hospital because of gross hematuria. Ultrasonogram showed a 4cm well-defined solid mass of the left renal pelvis. Intravenous pyelography revealed compression of the left upper pelvicocalyceal system by the mass with contrast filling within the mass. CT scan revealed Iobulated well defined mass in the left renal pelvis extending into renal parenchyme. A transitional cell carcinoma or renal cell carcinoma was suspected radiologically, and the patient underwent left total nephrectomy. In pathology, the lesion turned out to be a subepithelial hemaroma. In the differential diagnosis of renal malignancy, a subepithelial hematoma of the renal pelvis may be included.

OBJECTIVE: In this five-year cohort study, we hypothesize that factors of temperament and character in professional baseball players predict the speed of obtaining success and the quality of success as well as anxiety control. METHODS: Participants included 120 male rookie players from the Korea Baseball Organization (KBO) and 107 male non-players with no history of playing baseball. The personality/characters and state/trait anxieties of participants were assessed with the Temperament and Character Inventory (TCI) and Spielberg's State-Trait Anxiety Inventory-Y (STAI-Y). Over the duration of five years, all the players were subsequently classified into either a success group (major leaguers) or a non-success group (non-major leaguers), depending on their status in the professional baseball league in Korea. RESULTS: The players in the group of starters had higher novelty seeking (NS) scores than those of non-starters. The reward dependence (RD) scores of the success group were higher than those of the non-success group. The state anxiety scores in the starter group were negatively correlated with NS scores. The state and trait anxieties in the non-success group were positively correlated with RD scores. CONCLUSION: The results of this study suggest that predictive temperamental factors for success in baseball players include traits of novelty seeking and reward dependence.

OBJECTIVES: The aim of this meta-analysis study was to examine the relationship between cognitive anxiety and performance in closed loop skill sports. METHODS: A comprehensive literature search was conducted using databases including Korean Information Service System, DBpia, Research Information Sharing Service, and National Assembly Library from 1980 to 2015. Search terms included ‘Golf’, ‘Shooting’, ‘Archery’, ‘Anxiety’, and ‘Performance’. Standardized mean difference and 95% CI(confidence intervals) were calculated, and the heterogeneity of the studies was estimated using Q statistic. RESULTS: Ten studies have satisfied the inclusion criteria. The main findings indicate that cognitive anxiety was significantly reverse correlated with performance in closed loop skill sports(r=-.198). The mean effect size for men(r=-.31) was significantly greater than that for women(r=-.05). CONCLUSIONS: Our results suggest that cognitive anxiety in closed loop skill sports is correlated with performance of athletes. Future study related to psychological aspects on athletes in sports is required in order to understand the specific evidence of relationship between anxiety and performance.

OBJECTIVE: To determine whether a routine ultrasonography (US) is necessary for diagnosis of developmental dysplasia of hip (DDH), presenting with congenital muscular torticollis (CMT). METHODS: Cases of 133 patients (81 males, 52 females) diagnosed as CMT were reviewed, retrospectively. We reviewed the medical charts and diagnostic examination. We also assessed the coincidence of CMT and DDH, and investigated the clinical features of CMT related to DDH. RESULTS: Twenty (15.0%) patients out of 133 CMT patients were diagnosed as having DDH by US. Of whom, 8 patients were radiographically positive and 4 patients were both clinically and radiographically positive. Nine patients were treated with a harness and 1 of them needed closed reduction and casting. Out of 9 patients treated with a harness, only 4 were clinically positive. The difference and ratio of the sternocleidomastoid (SCM) muscle thickness between the normal and abnormal side was significantly greater in DDH patients (p=0.014). Further, receiver operating characteristic analysis showed when the SCM ratio is greater than 2.08 and the SCM difference is greater than 6.1 mm, the efficiency of US for the diagnosis of the DDH was found to be the best (p<0.05). CONCLUSION: To evaluate DDH, physical examination showed low sensitivity and radiologic study has limitation for the child before 4 to 6 months of age. Therefore, we recommend that hip is screened by US for the diagnosis of DDH associated with CMT when physical examination is positive or CMT patients with large SCM difference and high SCM ratio.

PURPOSE: To evaluate prognosis-related CT findings in hypoxic ischemic encephalopathy. MATERIALS AND METHODS: For the purpose of prognosis, 28 children with a clinical history and CT findings suggestive of hypoxic ischemic encephalopathy (HIE) were restrospectively reviewed. The diagnostic criteria for HIE, as seen on CT scanning, were as follows : 1, ventricular collapse ; 2, effacement of cortical sulci ; 3, prominent enhancement of cortical vessels ; 4, poor differentiation of gray and white matter ; 5, reversal sign ; 6, obliteration of perimesencephalic cistern ; 7, high density on tentorial edge, as seen on precontrast scans ; and 8, low density in thalamus, brain stem and basal ganglia. On the basis of clinical outcome, we divided the patients into three groups, as follows : group I(good prognosis) ; group II(neurologic sequelae), and group III(vegetative state or expire), and among these, compared CT findings. RESULTS: There were thirteen patients in group I, six in group II, and nine in group III. Ventricular collapse, effacement of cortical sulci, and prominent enhancement of cortical vessels were noted in all groups, whereas poor differentiation of gray and white matter, reversal sign, obliteration of perimesencephalic cistern, high density on tentorial edge, on precontrast scan, and low density in brain stem and basal ganglia were observed only in groups II and III. CONCLUSION: CT findings showed distinct differences between groups in whom prognosis was good, and in whom it was poor. An awareness of poor prognostic CT findings may be clinically helpful in the evaluation of patients with hypoxic ischemic encephalopathy.

PURPOSE: The purposes our study was to find out any histologic factors associated with negative conversion of axillary lymph node (ALN) after neoadjuvant chemotherapy (NAC). We also evaluated the association between the decrease in size of primary breast tumor and negative conversion of ALN. METHODS: From January 2012 to November 2014, we included 133 breast cancer patients who underwent NAC and who had ALN metastases which were confirmed on fine-needle aspiration or core needle biopsy at initial diagnosis. All 133 patients underwent initial magnetic resonance imaging (MRI) at the time of diagnosis and preoperative MRI after completion of NAC. We measured the longest dimension of primary breast cancer on MRI. RESULTS: Of 133 patients, 39 patients (29%) showed negative conversion of ALN and of these 39 patients, 25 patients (64%) showed pathologic complete remission of primary breast. On univariate analysis, mean percent decrease in longest dimension, estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 status and histologic grade were significantly associated with the ALN status after NAC (p<0.001, p=0.001, p< 0.001, p=0.001, p=0.002, respectively). On multivariate logistic regression analysis, percent decrease in longest dimension (odds ratio, 1.026; 95% confidence interval [CI], 1.009-1.044) and histologic grade (odds ratio, 3.964; 95% CI, 1.151-13.657) were identified as being independently associated with the ALN status after NAC. The area under the receiver operating characteristic curve was 0.835 with the best cutoff value of 80% decrease in longest dimension. Combination of high histologic grade and more than 80% decrease in longest dimension showed 64% sensitivity and 92% specificity. CONCLUSION: High histologic grade and more than 80% decrease in primary tumor dimension were associated with negative conversion of ALN after NAC.

A ganglion cyst is a relatively common benign tumor on the wrist. Conservative and surgical approaches have been used for its treatment. Various conservative treatment methods have been suggested such as reassurance, aspiration, sclerosant injection, and direct compression. But, there is no acceptable treatment of choice yet because each suggested method has a relatively high recurrence rate. We want to report two cases in which the size of the wrist ganglion was decreased by using electroacupuncture. One patient presented with a chronic ganglion for six years and the other patient presented with a recently occurred acute ganglion. We applied electroacupuncture for 20 minutes once a week for eight weeks to both of them. Afterwards, the size of the wrist ganglion diminished in the follow-up sonography and the accompanying pain was also relieved. Herein we report both cases along with a review of the relevant literature.
