The purpose of this study was to identify the effects of the application of elastic compression stockings and lower extremities exercise on edema and pain of lower extremities in hospital nurses. The participants were 30 hospital nurses working at a general hospital. The participants were categorized into three groups such as, 10 for an experimental group of the application of the elastic compression stocking, 10 for another experimental group of the application of Lower extremities exercise and 10 for a control group. Edema of the lower extremities were measured in terms of the girths of ankles and calves. And pain of the lower extremities were measured in terms of the score by NRS(Numerical Rating Scale). The data were analyzed with Frequency, Percentage, Mean, Standard Deviation, ${\chi}^2$-test and ANOVA to identify the participants' characteristics, SPSS Win 21.0 program was used for analysing. There are significant differences in lower extremity edema among the experimental group of lower extremities exercise, experimental group of elastic compression stocking and control group was supported(Rt Calf F=0.645, p=.000, Lt Calf F=21.941, p=.000). There are significant differences in lower extremity pain the experimental group of lower extremities exercise, experimental group of elastic compression stocking and control group was supported(Rt: F==7.320, p=.000 Lt: F=10.623, p=.000). In conclusion, in has been appeared that the lower extremities exercise and wearing elastic compression stocking have effedted in relieving low extremity edema and pain scale for nurses.

Nuclear medicine imaging is widely used in pain medicine. Low back pain is commonly encountered by physicians, with its prevalence from 49% to 70%. Computed tomography (CT) or magnetic resonance imaging (MRI) are usually used to evaluate the cause of low back pain, however, these findings from these scans could also be observed in asymptomatic patients. Bone scintigraphy has an additional value in patients with low back pain. Complex regional pain syndrome (CRPS) is defined as a painful disorder of the extremities, which is characterized by sensory, autonomic, vasomotor, and trophic disturbances. To assist the diagnosis of CRPS, three-phase bone scintigraphy is thought to be superior compared to other modalities, and could be used to rule out CRPS due to its high specificity. Studies regarding the effect of bone scintigraphy in patients with extremity pain have not been widely conducted. Ultrasound, CT and MRI are widely used imaging modalities for evaluating extremity pain. However, SPECT/CT has an additional role in assessing pain in the extremities.

Schwannomas are rare and distinctive nerve sheath tumors. They occur commonly along the course of central and peripheral nerves, especially on the skin of the head, neck and extremities. Histologically, they are characterized by Antoni A and Antoni B tissues of high and low cellularity. 2 cases of intrapulmonary Schwannomas were reported worldwide by 1980. We report a case of twenty seven-year-old male patient with intrapulmonary Schwannoma, who had multiple nodules on the skin of the both upper extremities and scrotum with their characteristic findings.

There are several advantages for groin flap, but its small and unpredictable vessels of pedicle have made it to lose its initial popularity. Although it would be ideal flap when it is focused on its useful advantages such as relative larger size, low donor site morbidity and possible bone graft, there have been few studies for prognostic factors for successful groin flap. Authors intended to determine prognostic factors which are relative with success of free groin flap. From January 1985 to December 2007, 107 patients who underwent groin flap for reconstruction of extremities were selected consecutively. Univariate and multivariate analysis were performed to determine prognostic factors which were related with success of groin flap. Eighty of 107 (74.8%) flaps survived. There was significant difference in success rate according to the recipient site. Nineteen of 20 cases (95%) survived in upper extremities, but 61 of 87 cases (70.1%) survived in lower extremities, which was statistically significant (p=0.022). Univariate analysis showed that mean diameter of donor veins was significantly larger in success group (p=0.021). Groin flap is recommended for reconstruction of upper extremities than lower extremities. It is thought to be critical that surgeons try to match vessel diameters between donor and recipient site.

Although tuberculosis of the central nervous system is well known, the incidence of intramedullary tuberculomas is low and a combination of intramedullary with intracranial tuberculomas is extremely rare. We report a case of disseminated tuberculoma involving brain and spine with miliary pulmonary tuberculosis in a 66-year-old woman initially presenting with fever, general weakness, back pain and motor weakness of both lower extremities. Despite medical therapy, she developed progressive motor weakness of both lower extremities with muscle strength 1/5 in both lower extremities. Urgent surgical intervention was followed and her muscle power and motor functions were improved gradually. The anti-tuberculous drugs were continued and the follow-up magnetic resonance imaging (MRI) of brain and spine showed that the lesions had become smaller or disappeared.

Crashworthy design of trains is now indispensable procedure in modern railway vehicle design for ensuring the safety of Passengers and crew. It is now widely recognized that a more strategic approach is needed in order to absorb higher level energy in a controlled manner and minimize passenger injuries effectively. The first design step in this strategic approach is the design of the front end structure(so called HE extremities) to absorb a large part of total impact energy and then the structure of passengers non-accommodation zones(so called LE extremities) is designed to absorb the rest of impact energy. In this paper, the passengers entrance door area is selected as the LE(low energy) extremities and the design of the LEE was carried out. The main part of LEE design procedures is the design of energy absorbing tubes. For this purpose, the several tube candidates are introduced and compared to each others with numerical crash simulation.

Purpose. The purpose of this study was to evaluate the effects of calf muscle massage on the balance of low extremities and flexibility of both ankles. Methods. The subjects were 16 healthy adults(men 8, women 8). The group was applied effleurage, tapotement, pressure forms of massage on their calf muscles. The intervention was offered during 3 minutes per one leg, to a total of 6 minutes. We assessed their balance and flexibility of both ankles using Functional reaching test(FRT) and One leg standing test(OLST) with trampoline before and after applying massage. Results. In this study, the data shows the ability of FRT and the ability of OLST with trampoline is improved in massage group. Conclusions. These results suggest that massages help to improve the balance of low extremities and the flexibility of both ankles.

We experienced an abdominal obese patient with postpartum disease. From the 15th of July 2006 to the 16th of September 2006 we applied herbal medications (Gungguijohyeoleumgamibang and Taeeumjouitanggamibang), acupuncture, auricular acupuncture, electrolipolysis, low calorie diet, aerobic exercise, behavioral therapy to her. We examined the changes in body weight, BMI, PBF and WHR and the changes in cold hypersensitivity of lower extremities and pain of wrists and ankles. Her weight decreased from 49.6kg to 44.5kg, BMI from $20.9kg/m^2$ to $18.8kg/m^2$, PBF from 27.7% to 23.9%, WHR from 0.84 to 0.78. Cold hypersensitivity of lower extremities and pain of wrists and ankles, symptoms typical of postpartum disease disappeared after treatment. Despite a low calorie diet, lactational performance was not impaired.
