Real-Time Exercise Feedback through a Convolutional Neural Network: A Machine Learning-Based Motion-Detecting Mobile Exercise Coaching Application

Purpose@#Mobile applications are widely used in the healthcare market. This study aimed to determine whether exercise using a machine learning-based motion-detecting mobile exercise coaching application (MDMECA) is superior to video streamingbased exercise for improving quality of life and decreasing lower back pain. @*Materials and Methods@#The same 14-day daily workout program consisting of five exercises was performed by 104 participants using the MDMECA and another 72 participants using video streaming. The Medical Outcomes Study Short Form 36-Item Health Survey (SF-36) and lower back pain scores were assess as pre- and post-workout measurements. Scores for the treatment-satisfaction subscale of the visual analog scale (TS-VAS), intention to use a disease-oriented exercise program, intention to recommend the program to others, and available expenses for a disease-oriented exercise program were determined after the workout. @*Results@#The MDMECA group showed a higher increase in SF-36 score (MDMECA, 9.10; control, 1.09; p<0.01) and a greater reduction in lower back pain score (MDMECA, -0.96; control, -0.26; p<0.01). Scores for TS-VAS, intention to use a disease-oriented exercise program, and intention to recommend the program to others were all higher (p<0.01) in the MDMECA group. However, the available expenses for a disease-oriented program were not significantly different between the two groups. @*Conclusion@#The MDMECA is more effective than video streaming-based exercise in increasing exercise adherence, improving QoL, and reducing lower back pain. MDMECAs could be promising tools of use to achieve better medical outcomes and higher treatment satisfaction.

Hemodynamic Consideration in Intraoperative Neurophysiological Monitoring in Neuromuscular Scoliosis Surgery

Objective@#To prove the hypothesis that the parameters of intraoperative neurophysiological monitoring (IONM) during will be more deteriorated in neuromuscular scoliosis (NMS) than in adolescent idiopathic scoliosis (AIS). @*Methods@#This retrospective study reviewed the data of 69 patients (NMS=32, AIS=37) who underwent scoliosis surgery under IONM. The amplitude of motor evoked potentials (MEPs), and the amplitude and the latency of somatosensory evoked potentials (SEPs) were examined. Demographic, preoperative, perioperative and postoperative data were analyzed to determine whether they affected the IONM parameters for each group. @*Results@#Of the items analyzed, the bleeding amount was the only significant risk factor for SEP latency deterioration in the NMS group only. The amplitude of SEP and MEP did not correlate with the hemodynamic parameters. The NMS/AIS ratios of the bleeding-related parameters were higher in the order of bleeding amount/weight (2.62, p<0.01), bleeding amount/body mass index (2.13, p<0.01), and bleeding amount (1.56, p<0.01). This study suggests that SEP latency is more vulnerable than SEP or MEP amplitude in ischemic conditions during scoliosis surgery. @*Conclusion@#In NMS patients, it should be considered that the bleeding amount can have a critical effect on intraoperative electrophysiological deterioration.

A Case of Bilateral Testicular Teratoma Found in Infant / 영남의대학술지

Testicular teratoma is characterized that has more than one germ cell layer in various stages of maturation and differentiation. The incidence of mature teratoma varies from 2 to 9% of all germinal testicular tumor. Only 3 cases of bilateral teratoma have been reported in the literature to date. The teratoma can occurs at all ages but is most common between the age of 15-35 year. It is relatively infrequently seen in childhood and infancy. In these age group, teratoma tends to be a benign. Recently, we experienced one case of bilateral testicular teratoma in 4 month-old infancy. We report a case of bilateral testicular teratoma found infancy with review of related literatures.

Effects of Functional Magnetic Stimulation Therapy on Lower Urinary Tract Symptoms and Sexual Function in Female Patients with Stress Urinary Incontinence / 대한비뇨기과학회지

PURPOSE: The aim of this study was to evaluate the efficacy of functional magnetic stimulation (FMS) therapy on the lower urinary tract symptoms (LUTSs) and sexual function in female patients with stress urinary incontinence (SUI). MATERIALS AND METHODS: 39 sexually active women, with SUI treated by FMS therapy, were studied. Before treatment, female bladder questionnaires and a visual analog scale test (VAT) were used to acquire information relating to LUTS. Questions were asked about sexual function using the female sexual function index (FSFI). Treatments were performed for 20 minutes, twice a week, for 6 weeks. After treatment, the same questionnaires were repeated at 3, 6 and 12 months. The patients were divided into two groups: those with cured or improved SUI symptoms were defined as the success group, with the remainder defined as the failure group. The VAT scores of LUTSs, the domain scores and full scale scores of FSFI were analyzed. RESULTS: The success and failure groups comprised of 25 (64%) and 14 (36%) patients, respectively. In both groups, the frequency, urge incontinence and dysuria were improved. The VAT score for the overall satisfaction was significantly decreased in the success group only (p<0.05). In the success group, the domain score for 'satisfaction' in the FSFI was significantly increased (p<0.05). The full scale scores of the FSFI were significantly increased in the success group only (p<0.05). CONCLUSIONS: These results show that FMS therapy improves some LUTSs and sexual functions, with the correction of SUI symptom. Therefore, FMS therapy could be considered as a primary therapy in SUI women with LUTSs and sexual impairment.

A Case of Infected Huge Lymphangioma in Pelvic cavity / 영남의대학술지

Lymphangioma is a benign tumor resulted from abnormal communication between large dermal lymphatic channels and central lymphatic system. The tumor is encountered more often in the neck and axilla and less often in mediastinum, omentum, retroperitoneum, and scrotum. It rarely developed at urogenital system, and there has been no previous description of lymphangioma involving the bladder wall in Korea. We report a case of 35-year-old female with infected huge lymphagioma arising from pelvic cavity and involving bladder wall.
