  • Purpose : Authors investigated the efficiency of preoperative MRI in suspicious glomus tumor and the clinical outcomes after marginal excision. Materials and Methods : In 10 cases of glomus tumors in the fingers, authors retrospectively analyzed the clinical data, including previous trauma, treatment history, preoperative symptoms, physical examination, plain radiography, MRI (9 cases), pathological findings and postoperative complications. Results : The patients had pain in 10 cases, tenderness in 9 cases, cold sensitivity in 3 cases and edema in one case. MRI showed low signal (3 cases) or iso-signal (5) intensity on T1 weighted image, high signal intensity (8) on T2 weighted image, and all the lesions were enhanced in gadolinium enhancement images. The exact locations of glomus tumors were median in 6 cases, lateral in 5, lateral fold in 2 and pulp in 3 in transverse section and nail bed in 5 cases and nail matrix in 5 in sagittal section. Marginal excision was performed by lateral approach in one case and transungual in 9 cases. Histologically, all 10 cases were composed of solid sheets of round cells interrupted by thin-walled blood vessels. Most of clinical symptoms were disappeared in all cases after operation. Nail deformity was found in one case, which was originated from nail matrix, however, there was no recurrence. Summary : Clinical symptom was the most impotant factor in diagnosis of glomus tumor in the fingers. However, preoperative MRIs were helpful in patients, who had obscure pain or prolonged clinical symptoms with suspicious glomus tumors. Preoperative MRI might be one of the most useful tools for establishing the exact diagnosis and detecting the location of glomus tumors, in spite of the relatively high expenses.

  • A measurement unit and signal processing algorithm have been developed for predicting arterial oxygen saturation noninvasively. The measurement set-up was composed of a probe including light source and photodetector, optical signal processing section, LED driving circuit, PC interface software for data acquisition and data processing software. Light from the LED's was irradiated onto the finger nail bed and transmitted light was measured at different wavelengths. An effective baseline correction method was developed and measured data were analyzed by using various data processing methods and prediction algOlithms. For performance evaluation, a pulse oximeter simulator (Bio- Tek Instrument Inc.) was used as reference. The best performance in terms of the correlation coefficient and the standard deviation was obtained under the following conditions; when the arterial signals were computed in terms of area rather than peak-valley difference, and when the algorithm calculating by $In(I_p/I_v)/I_{avr}$ value for pulsation waveform was used. In in vivo test, prediction was improved when the developed baseline correction method was used. In addition, wavelengths of 660 nm and 940 nm provided better linearity and precision than wavelengths of 660 nm and 805 nm. 05 nm.

  • Purpose: Glomus tumors are uncommon benign neoplasms arising from the neuromyoarterial apparatus, usually seen in the nail bed of fingers. Most of this mass presents typical symptoms such as severe pain, point tenderness and hypersensitivity to cold like neuroma, gout or causalgia. Concerning about the origin, there were few written reports about extra-digit glomus tumor, especially that occurred in the skeletal muscule. Methods: A 48-year-old female complained of painful tender mass in her right calf aggravated several months ago. Her MRI and femoral angiogram showed a well defined hypervascular tumor such as hemagioma or hemagioendothelioma in the right calf. Surgical treatment was performed, and it proved glomus tumor in soleus muscle histologically. Results: After the operation, patient didn't complain of her symptoms any more and there was no evidence of recurrence during 1 year follow-up period. Conclusion: Authors have found only eight cases of intramuscular glomus tumor reported in the literature and present here the ninth case of an intramuscular glomus tumor and first case of soleus muscle.

  • In order to establish the manifestational symptoms in men and women and highly frequent symptoms(HFS) of deficiency of Qi and blood(氣虛, 血虛), stagnation of Qi(氣滯), deficiency of Yin(陰虛), deficiency of Yang(陽虛), and, 546 questionaires were analyzed through Cronbach alpha value and Pearson's correlative efficient. Symptomatic differences of male and female specimens were as follows. HFS of Qi deficiency were similar in terms of inactivity like mental and physical fatigue, enervation in men and women. In blood deficiency, dizziness and light sleep were common in men and women, but mucosal symptoms of conjunctiva, lip, nail bed were more frequent in women than men. Emotional explosion was common in Qi stagnation, then women had more motivation-related symptoms than men. Inner heat was frequently arisen in Yin deficiency in both, and the heat was expressed more common in exterior and upper part in women but in interior abdominal part in men. In Yang deficiency, main symptoms of men were feeling coldness in peripheral, but Qi deficiency symptoms were more common in women former than coldness.
