A 56 years old male patient adklitted to our neurology department because of repeated tingling sensation in right 3, 4, 5th. (infers and weakness on grasping, which were progressively developed re ently. At this time, he had also suffered from claudication in both lower extremities. Carotid angiogram showed that right internal carotid artery was obstructed completely, and both common, both external and left internal carotid arteries had significant stenosis, Concommitantly, aortogram suggested complete obstruction just below the renal arteries. We plamled staged operation for two separated arterial lesions. Both carotid endarterectomy was performed. and we used carotid shunt for left side during operation. Abdominal aortic lesion was operated 2 weeks later We obligately clamped aorta just below the celiac artery and infuse4 kidney perservation solution to pertect kidney during ischemia. Reversed Y bypass graft and kidney perservation was successful despite of 40 minute ischemia. Postoperative courts was uneventful and patient was discharged without any specific problem.

Cutaneous leishmaniasis (CL) is an endemic parasitic infection in the Mediterranean region, including Libya and its Al-jabal Al-gharbi province. We aimed at studying the occupational relevance as well as other epidemiological aspects of CL. We investigated 140 CL cases who attended at Gharyan outpatient polyclinic during a period of 6 months in 2009. CL infection was clinically diagnosed and confirmed by demonstration of Leishmania parasites on smears from lesions. Our findings showed that males were more affected than females (P=0.04), and people above 10-years were more affected than younger ones (P=0.0001). A significant percent of CL cases belonged to Al-Kawasem subprovince (P=0.0001). Farm-related activities were the most frequent occupations among CL cases (P=0.04). In addition to farm workers, housewives and students are at risk groups since they are engaged at farm activities. Moreover, those who have occupations that require staying outdoors for a part of night, e.g., policemen, are also at risk. Compared to children, adult CL patients had multiple lesions (P=0.001) that were more prevalent in their upper and lower extremities than the face (P=0.0001). We conclude that CL is a major health problem in Al-jabal Al-gharbi province of Libya. The presence of rodents and sandflies makes it a suitable environment for Leishmania to spread in an endemic epidemiological pattern. Being engaged in farming activities or outdoor occupations increases the risk of infection. Various clinical patterns of CL suggest the presence of more than 1 species of Leishmania at Al-jabal Al-gharbi province. We propose that the 2 species responsible for CL in this area are L. major and L. tropica. Further investigations to identify the leishmanial species responsible for CL at Al-jabal Al-gharbi together with adoption of preventive and control programs are needed.

Neurotoxicity in the workplace may occur with exposure to scores of chemicals. Although large acute outbreaks of the occupational neurological disease are rare, the incidence of occupational neurotoxicity in its subtler aspects is unknown. A working knowledge of both the major occupational neurotoxic solvents and the tools used by cliniical neurologists and neurotoxicologists to evaluate neurotoxicity in working populations is a necessity fur the occupational physician. To investigate the effects of carbon disulfide($CS_2$) on the peripheral nerve system using the nervous conduction study, 105 male workers working in the spinning room of a viscose rayon factory were examined and compared with a sex and age matched, unexposed 105 male controls using t-test analysis. 72.4% of $CS_2$-exposed workers complained of neurological symptoms, and the abnormal cases in nerve conduction study were 48.6%. The abnormal cases of nerve conduction study increased in number according as the age and duration of exposure increased. In this study, asymptomatic workers were confirmed to have subclinical neuropathy by nerve conduction study. Also as there were abnormal cases even in its duration of exposure below 4 years, nerve conduction study turned out to be ways of discovering of early peripheral neuropathy. In nerve conduction study, the amplitude, velocity, F-wave latency and H-reflex of the motor and sensory nerves in both upper and lower extremities were significant different between $CS_2$-exposed workers and the controls. From the pathological viewpoint, both segmental and axonal degenerations were assumed in this study.

[ $Henoch-Sch{\"{o}}nlein$ ] purpura(HSP) is a systemic small vessel vasculitis characterized by cutaneous purpura, arthritis, abdominal pain and nephritis. The characteristic rash of HSP consists of palpable purpura on the buttocks and lower extremities. Bullous lesions often appear in adults with HSP, whereas they are very rare in children with HSP. In this case report, the patient presented with arthralgia and abdominal pain and had hemorrhagic bullae as a prominent manifestation of the disease. The skin biopsy of the patient revealed typical leukocytoclastic vasculitis of dermal vessels and prominent IgA and fibrinogen deposits on capillary walls by direct immunofluorescence. We confirmed the diagnosis of HSP and observed improvement of clinical symptoms and signs within a few days after corticosteroid treatment. We therefore report a case with a review of the literature.

Crowth of an angiolipoma of the central nervous system is rare. Only about 60 cases were searched in the literature. We report one case of spinal angiolipoma recently treated in our institution. A 67-year-old man was admitted because of burning sensation on the both lower extremities and paraparesis. He felt burning sensation on the both great toes and it progressively involved to thighs and inguinal area during the past 1 year which gradually worsened. MR image showed a spinal mass lesion at the level of T4 to T6. The lesion was isodense and hyperdense in periphery on T1-weighted image and hyperintense on T2-weighted image. The tumor was located on the posterior area of the spinal cord and markedly enhanced after intravenous Gd-DTPA. At the operation, a soft, dark-red mass was totally removed. On histological examination, the tumor was shown to be mainly composed of mature fatty cells and numerous blood vessels with enlarged lumens. Postoperative course was uneventful and the symptoms improved gradually.

Purpose: This study was conducted to examine the effect of foot-bath on lower extremities edema and fatigue among college students in Korea. Methods: This study used an quasi-experimental design with 56 participants (30 for experiments and 26 for controls). The experimental group performed 20-minute foot bath before sleep three times for one week. All subjects were directed to use their smart-phones to fill out a questionnaire about fatigue. Leg circumference was measured 10 minutes after foot bath. The test was performed from April 30th to May 22th in 2016. Data was analyzed using t-test and $x^2$ test. Results: We found no difference in general characteristics between the experimental group and the control group. Left leg edema of the experimental group decreased by $16.63{\pm}14.57mm$ (p<.001). The experimental group's right leg-edema decreased by $13.10{\pm}13.97mm$ (p<.001). There was no statistically significant difference in their fatigue level when comparing before and after the foot baths. Conclusion: We found that doing foot baths for two weeks could have positive effects in reducing leg-edema among college students. Foot bath may be applied as an effective nursing intervention to decrease leg edema among young people. The results are based on a limited number of study samples and a short-term intervention. Further research can be performed with extended population and a prolonged study period.

PURPOSE: Chronic low back pain is one of the main factors that affect the quality of life and cause problems of gait and balance in elderly people. This study investigated the correlation between the Oswestry disability index (ODI), Berg balance scale (BBS), and kinematic data measured while analyzing the gait of elderly people with chronic back pain. METHODS: A total of 29 subjects participated in this study. The ODI, BBS, and kinematic data of lower extremities were measured while walking. All data were analyzed using Pearson's correlation coefficients and the significance was measured at .05. RESULTS: ODI had a significant correlation with 1, 13, and 14 items of BBS (p < .05), and left hip external rotation and right ankle abduction respectively in the stance and swing phase of gait (p < .01). 13 items of BBS had a significant correlation with the right ankle abduction in the stance phase of gait (p < .01). In addition, 14 items of BBS had a significant correlation with right and left ankle abduction in the stance and swing phase of gait (p < .01). CONCLUSION: While attempting to predict chronic low back pain and balance issues, it may be useful to check the right ankle abduction in the stance and swing phase of gait. In the future, it would be helpful if some simple tests could be designed to assess balance in elderly people with chronic low back pain.

Whole body fatigue detection is an important phenomenon and the factors contributing to whole body fatigue can be controlled if a mathematical model is available for its assessment. This research study aims at developing a model that categorizes whole body exertion into fatigued and non-fatigued states based on physiological and perceived variables. For this purpose, logistic regression was used to categorize the fatigued and non-fatigued subject as dichotomous variable. Normalized mean power frequency of eight muscles from 25 subjects was taken as physiological variable along with the heart rate while Borg scale ratings were taken as perceived variables. The logit function was used to develop the logistic regression model. The coefficients of all the variables were found and significance level was checked. The detection accuracy of the model for fatigued and non-fatigues subjects was 83% and 95% respectively. It was observed that the mean power frequency of anterior deltoid and the Borg scale ratings of upper and lower extremities were significant in predicting the whole body fatigued when evaluated dichotomously (p < 0.05). The findings can help in better understanding of the importance of combined physiological and perceived exertion in designing the rest breaks for workers involved in squat lifting tasks in industrial as well as health sectors.

Background: The aim of this study was to investigate the clinical characteristics of complex regional pain syndrome (CRPS) in young male patients in South Korea, especially focusing on the association with military service. Methods: From January 2007 to May 2017, we investigated the electronic medical records of 430 consecutive patients, aged 18 to 30 years, who visited Seoul National University Hospital Pain Center, with a suspected diagnosis of CRPS at the initial visit. The following patient details were available for analysis: demographic and disease-related variables, relevance to military service, medications, and the treatment modalities received. Results: Out of 430 patients, 245 (57.0%) were diagnosed with CRPS, of which, 200 were male patients and 45 were female patients. Of the male patients, 95 (47.5%) developed CRPS during military service. CRPS during military service was more likely to result from sprain/strain, and the incidence of CRPS was significantly higher in the lower extremities in patients from the military service group than in those from the non-military service group. During the follow-up period, 37.9% of male CRPS patients (n = 61/161) were treated successfully. Patients with moderate to severe initial pain intensity, and diagnosed during their military service, showed better outcomes. Conclusions: Our results demonstrated that manifestation of CRPS in the young Korean population was more common in male and among those male CRPS patients, about half the cases developed during the military service period.

Purpose: Several published policy statements have warned against the risks associated with trampoline use and recommended safety guidelines. However, few studies have focused on trampoline-related injuries in Korea. This study aimed to assess the incidence and characteristics of pediatric trampoline-related injuries presented to Ulsan University Hospital. Methods: We retrospectively reviewed the medical records of children aged <16 years with trampoline-related injuries who visited our Emergency Department between 2008 and 2017. Results: Over the 10-year period, 178 trampoline-related injuries were reported, which represented a significant increase (P=0.016). Most (87.6%) of the injuries occurred during the last 5 study years, and a rapid increase in injuries was observed in children aged <6 years. Lower extremity injuries (62.4%) were the most common, followed by injuries of the upper extremities, head and face, and trunk, including injuries to the neck and spine. Sixty-seven children (37.6%) had fractures, and proximal tibia fractures were the most common. Fractures were significantly more common in younger children (<6 years old) than in older children (P=0.026). Conclusion: In Korea, the mechanism of trampoline injury is similar to that of injuries incurred in indoor trampoline parks but is characterized by smaller spaces and multiple users. Trampoline use and the incidence of trampoline-related injuries in children aged <6 years are increasing rapidly. Prohibiting the use of trampolines for children aged <6 years, restricting simultaneous use by multiple children, and ensuring adult supervision should be strictly emphasized. Public awareness and policy guidelines are needed to reduce the incidence of trampoline-related injuries.
