Dermatophytes invade the stratum corneum and infect the skin, nails, and hair, mostly resulting in superficial infections. Deep dermatophytosis involving the dermis and subcutaneous layer has rarely been reported in immunocompromised individuals. Herein, we report a case of deep dermatophytosis caused by Trichophyton rubrum. A 71-year-old woman presented with multiple erythematous exophytic and subcutaneous nodules in both the lower legs. The patient was taking immunosuppressive agents for rheumatoid arthritis and antifungal agents for tinea pedis and onychomycosis, which was improperly ceased. Histopathological findings showed diffuse granulomatous infiltration with multinucleated cells, lymphocytes, histiocytes, and neutrophils in the dermis. Septate and branched hyphae were observed in the dermis using periodic acid-Schiff diastase and Gomori methenamine silver staining. T. rubrum was identified in fungal culture from the tissue sample and confirmed through phylogenetic analysis of the internal transcribed spacer and large subunit regions in ribosomal ribonucleic acid gene. Intravenous amphotericin B was administered for septic shock before the confirmation of the causative organism, which rapidly improved the condition.

[목적] 골프 스윙 시 3가지 스탠스에서 볼의 정확성과 스피드를 유지하기 위한 신체의 전략을 수직지면반력과 근 전도 변인을 통하여 알아보고자 하였다. [방법] 연구의 대상은 대학 남자골프선수 10명이 참여하였다. 어드레스에 서 스탠스 형태를 스퀘어(SS), 오픈(OS), 클로즈드(CS) 스탠스로 설정하여 분석하였다. 3차원 동작분석 시스템과 지면반력기, 근전도를 이용하여 스탠스별 7번 아이언 풀스윙을 통하여 결과를 산출하였다. [결과] 스탠스별 수직 지면반력의 피크값에 대한 크기차이는 차이가 나타나지 않았다. 스탠스별 수직지면반력의 피크값에 대한 시간차 이는 FzT1, FzT2에서 차이가 나타나지 않았지만, FzT3은 SS가 OS와 CS보다 짧게 나타났고, FzT4는 CS가 SS와 OS보다 짧게 나타났다. 근전도값은 모든 구간에서 스탠스별 차이가 나타나지 않았지만, 탑 스윙에서 하지의 최대 근전도 도달 시간은 OS, CS, SS 순으로 빠르게 나타났고, 근육에 따른 차이는 LRF, RTA, RBF가 빠르게 나타났다. [결론] 스탠스의 위치에 따라 동일한 방향의 샷의 구사는 체중이 이동되는 시간에 영향을 미치고, 이에 따라 하지 근활성화되는 타이밍이 달라짐으로 인해 일정한 스윙이 유지되는 것으로 사료된다. [Purpose] The purpose of this study was to investigate body strategy to maintain the accuracy and speed of the ball in 3 stances during a golf swing through vertical ground reaction force and EMG variables. [Method] Ten male golfers were participate in the experiment. It was analyzed through stance conditions (square, open, closed) during swing. Using a 3D motion analysis system, a ground reaction force, and an EMG, the results were calculated with the 7th iron full swing per stance. [Result] In difference in magnitude, there was no difference of the peak value of the vertical ground reaction force. In difference in time, there was no between FzT1 and FzT2, but in FzT3, SS was shorter than that of OS and CS, and FzT4 showed shorter CS than that of SS and OS. There was no difference in EMG values for each stance in all sections, but the maximum EMG arrival time of the lower extremities in the top swing appeared in the order of OS, CS, and SS, and LRF, RTA, and RBF showed rapid differences according to muscles. [Conclusion] Therefore, it is considered that the position of the stance affects the time the body weight moves in order to make full use of the shot in the same direction, and accordingly, the activation time of the lower extremity EMG is changed, so that a constant swing is maintained.
