  • 본 연구는 다양한 찬물 온도에 손가락을 침수시켰을 경우 추위유발성혈관확장(Cold-induced vasodilation)이 어떻게 나타나며, 이 반응이 재발현되는지 평가하는데 목적을 두었다. 이를 위해 10명의 건강한 대학생($21.4{\pm}2.5$ yrs, $175.8{\pm}4.1$ cm, $69.6{\pm}7.6$ kg, $11.2{\pm}3.7$ %fat)이 두 번의 실험에 참가하였다. 첫 번째 실험은 상온환경에서 다섯 번의 실험과정 반복으로 이루어졌다. 실험과정은 $43^{\circ}C$의 물에 오른손 가운데 손가락을 5분 동안 담갔다가, 그 후 25분 동안 상온에서 휴식을 가지고, 그 다음 무작위로 물 온도 5, 8, 11, 14, 또는 $17^{\circ}C$ 중 하나에 손가락을 담갔다. 한 과정이 끝나면 다른 수온에서 같은 방식으로 실험이 진행되었다. 재발현 반응을 평가하기 위해 첫 실험 후 최소 5일 후에 같은 방법으로 두 번째 실험이 진행되었다. 실험 중 심박수, 직장온도, 손톱주위온도가 매 6초마다 측정되었다. 결론적으로 재현성에는 최대손가락온도(Tfmax)와 Tfmax-물온도(Tw)에서 재생산 반응을 보였다. 추위자극에 따른 CIVD의 반응은 추위자극이 높을수록 최소손가락온도(Tfmin)와 Tfmax의 반응은 높게 나타났으며, 추위자극이 낮을수록 Tfdiff의 반응은 증가되었다. 그러나 모든 반응시간에는 유의한 차이는 보이지 않았다.

  • Background Glomus tumors were first described by Wood in 1812 as painful subcutaneous tubercles. It is an uncommon benign neoplasm involving the glomus body, an apparatus that involves in thermoregulation of cutaneous microvasculature. Glomus tumor constitutes 1%-5% of all hand tumors. It usually occurs at the subungual region and more commonly in aged women. Its classical clinical triad consists of pain, tenderness and temperature intolerance, especially cold sensitivity. This study reviews 15 cases of glomus tumor which were analyzed according to its anatomic location, surgical approach and histologic findings. Methods Fifteen patients with subungual glomus tumors of the hand operated on between January 2006 and March 2013, were retrospectively reviewed. Patients were evaluated preoperatively with standard physical examination including ice cube test and Love's test. Diagnostic imaging consisted of ultrasonography, computed tomography, and magnetic resonance imaging. All procedures were performed with tourniquet control under local anesthesia. Eleven patients underwent excision using the transungual approach, 3 patients using the volar approach and 1 patient using the lateral subperiosteal approach. Results Total of 15 cases were reviewed. 11 tumors were located in the nail bed, 3 in the volar pulp and 1 in the radial aspect of the finger tip. After complete excision, patients remained asymptomatic in the immediate postoperative period. In the long term follow up, patients exhibited excellent cosmetic results with no recurrence. Conclusions Accurate diagnosis should be made by physical, radiologic and pathologic examinations. Preoperative localization and complete extirpation is essential in preventing recurrence and subsequent nail deformity.
