The precise role of radiotherapy for low grade gliomas including the optimal radiation dose and timing of treatment remains unclear. The information given by a retrosepctive analysis may be useful in the design of prospective randomized studies looking at radiation dose and time of surgical and radiotherapeutic treatment. The records of 56 patients (M:F=29:27) with histologically verified cerebral low grade gliomas(47 cases of grade 1 or 2 astrocytomas and 9 oligodendrogliomas) diagnosed between 1979 and 1989 were retrospectively reviewed. The extent of surgical tumor removal was gross total or radical subtotal in 38 patients(68%) and partial or biopsy only in the remaining 18 patients(32%). Postooperative radiation therapy was given to 36 patients(64%) of the total 56 patients with minimum dose of 5000 cGy (range=1250 to 7220 cGy). The 5-and 10-year survival rates for the total 56 patients were 44% and 32% respectively with a median survival of 4.1 years. According to the histologic grade the 5- and 10-year survivals were 52% and 35% for the 24 patients respectively with grade I astrocytomas compared to 20% and 10% for the 23 patients with grade II astrocytomas. Survival of oligodendroglioma patients was greater than those with astrocytoma (65% vs 36% at 5 years), and the difference was also remarkable in the long term period of follow up (54% vs 23% at 10 years). Those who received high-dose radiation therapy (> or =5400 cGy) had significant better survival than those who received low-dose radiation(< 5400 cGy) or surgery alone (p<0.05). The 5-and 10-year survival rates were, respectively 59% and 46% for the 23 patients receiving high-dose radiation, 36% and 24% for the 13 patients receiving low-dose radiation, and 35% and 26% for the 20 patients with surgery alone. Survival rates by the extent of surgical resection were similar at 5 years (46% vs 41%), but long term survival was quite different (p<0.01) between total/subtotal resection and partial esection/biopsy (41% and 12%, resepctively). Previously published studies have identified important prognostic factors in these tumor : age, extent of surgery, grade, performance status, and duration of symptoms. But in our cases statistical analysis revealed that grade I histology (p<0.025) and young age (p<0.001) were the most significant good prognostic variables.

PURPOSE: Although magnetic attachment is used frequently for overdenture, it is reported that attractive force can be decreased by abrasion and corrosion. The purpose of this study was to establish the clinical basis about considerations and long term prognosis of overdenture using magnetic attachments by investigating the change in attractive force of magnetic attachment applied to the patients. MATERIALS AND METHODS: Among the patients treated with overdenture using magnetic attachments in Dankook University Dental Hospital, attractive force records of 61 magnetic attachments of 20 subjects who re-visited from July 2013 to June 2014 were analyzed. Dental magnet tester (Aichi Micro Intelligent Co., Aichi, Japan) was used for measurement. The magnetic attachments used in this study were Magfit IP-B Flat, Magfit DX400, Magfit DX600 and Magfit DX800 (Aichi Steel Co., Aichi, Japan) filled with Neodymium (NdFeB), a rare-earth magnet. RESULTS: Reduction ratio of attractive force had no significant correlation with conditional variables to which attachments were applied, and was higher when the maintenance period was longer (P<.05, r=.361). Reduction ratio of attractive force was significantly higher in the subject group in which attachments were used over 9 years than within 9 years (P<.05). Furthermore, 16.39% of total magnetic attachments showed detachment of keeper or assembly. CONCLUSION: Attractive force of magnetic attachment is maintained regardless of conditional variables and reduction ratio increased as the maintenance period became longer. Further study on adhesive material, attachment method and design improvement to prevent detachment of magnetic attachment is needed.

Electrical stimulation has been used for evaluating central motor system and deep portion of peripheral nerve, but it was painful. And then magnetic stimulation was introduced recently and used widely because it was painless and easily repeated, compared to electrical stimulation. This study was undertaken in order to obtain normal valued of motor evoked potentials by transcranial magnetic stimulation. Ninety-two volunteers, free of neurological disease, were tested with Medelec Magstim model 200 and Medelec MIstral. There were 55 male and 37 female, ranging in height from 130 to 180 centimeter, with a mean height of 165.9 centimeter, in age from 13 to 70 years, with a mean age of 34 years. Transcranial magnetic stimulation cause contralateral hand and foot muscle responses, and the resultant motor evoked potentials can be recorded. Stimulating sites were near vertex in head, Erb's point in cervical region and L45 interspace in lumbar region. Recording sites wre abductor pollicis brevis(APB) in hand and abductor hallucis(AH) in foot. Our results were as follow ; 1) Latency between head and contralateral APB was 20.9+/-1.5ms, latency between cervical region and ipsilateral APB was 11.7+/-1.1ms, and there-by CMCT was 9.2+/-1.1ms. 2) Latency between head and contralateral AH was 39.0+/-2.6ms, latency between lumbar region and ipsilateral AH was 20.9+/-2.1ms, and there-by CMCT was 1.8+/-2.0ms. 3) Latency was statistically well correlated with subject height, but not CMCT. 4) There was no statistical significance, between male and female, right and left side, among age group, in latency and CMCT. 5) By voluntary muscle contractions, latency was shortened and amplitude was increased on vertex stimulation, but not hanged on stimulation of cervical and lumbar region. 6) By incraesing stimulus intensity, latency was shortened and amplitude was increased on vertex stimulation, but amplitude only was increased on stimulation of cervical region.

BACKGROUND: Presenteeism refers to the phenomenon of working while sick. Its development can be attributed to not only somatic symptoms but also underlying social agreements and workplace atmosphere. In this study, we analyzed presenteeism among workers from various industries, focusing on job-related stress with stratification on the presence of depression. METHODS: We conducted the study with data from questionnaires filled in by different enterprises enrolled in the Federation of Korean Trade Unions. Workers' depressive symptoms were investigated using the Patient Health Questionnaire-2, while questions on job-related stress and presenteeism were derived from the short form of the Korean Occupational Stress Scale and the official Korean version of the Work-Productivity and Activity Impairment Questionnaire-General Health, respectively. Multilevel logistic analysis was conducted to determine the statistical differences derived from the differences between companies. RESULTS: In total, 930 participants (753 men and 177 women) from 59 enterprises participated in the research. We conducted multilevel logistic regression to determine the association between the variables and presenteeism, with stratification by the presence of depression. Higher job demands and higher interpersonal conflict showed significantly elevated odds ratios (ORs) in univariate models and in the multivariate multilevel model. In the final model of total population, fully adjusted by general and work-related characteristics, higher job demands (OR: 3.29, 95% confidence interval [CI]: 2.08–5.21) and interpersonal conflict (OR: 1.87, 95% CI: 1.29–2.71) had significantly higher ORs—a tendency that remained in participants without depression. CONCLUSIONS: This study reflected the factors associated with presenteeism among workers from various enterprises. The findings revealed that job-related stress was closely related to presenteeism in both the total population and in the population without depression. Thus, it emphasized interventions for managing job stress among workers to reduce presenteeism in general workers' population.

Free -flap which is transferred to recipients is a thin flat tissue isolated from human body and nutrient vessel of free - flap is ligated with similarly sized vessel. Free -flap reconstruction is widely used, due to high rate of flap survival and functional refinements, although it gives disadvantage of long surgery time and inefficient adaptation. This study demonstrates the characteristics and arterial supply of rectus femoris muscle of thigh. Seventy thighs (35 right, 35 left) of the 35 cadavers (19 males/16 females) which were clinically normal and without deformity were dissected and measured, according to Martin measurements. 1. The average length and width of rectus femoris muscle were 396.7 +/-39.9 mm and 36.5 +/-7.9 mm, respectively. The length of female subjects was significantly different from that of male subjects (P 0.05). 2. In the origin and insertion of rectus femoris muscle, anterior tendon and posterior tendon were not different between female and male subjects. 3. Artery of the rectus femoris muscle arises from deep femoral artery. The length of pedicle from the entering point of the rectus femoris muscle was average 19.0 +/-11.9 mm. The length from the entering point of the rectus femoris muscle to spliting point was 13.7 +/-7.7 mm of P1, 12.6 +/-7.5 mm of P2, and 14.8 +/-11.63 mm of P3 pedicles. 4. The frequency of the blood vessels inserted into the rectus femoris muscle was the first highest at the portion of 32.5 ~35% and the second highest of 35 ~37.5% and 37.5 ~40% ranges, when anterior superior iliac spine from center of the patellar was considered as 100% of portion. 5. According to the method by Kimata et al. (1998) classifying perforators based on the anatomic variations, type 1 and VIII were 83.58% and 5.97% respectively. Type 5, 6 and 7 were not observed. 6. Femoral nerves inserted into the rectus femoris muscle were distributed within 7.5 ~45% portion when anterior superior iliac spine from center of the patella was converted into 100%. The portion of 17.5 ~20% had the highest frequency of nerves. In conclusion, length of the rectus femoris muscle in Korean were different depending on gender, whereas tendon lengths were not. These data demonstrate artery pattern in Korean and provide anatomical potential for rectus femoris muscle to be used as a free -flap muscle.

We report our experience with a case of performing laparoscopy-assisted total gastrectomy along with pancreas-preserving splenectomy for treating early gastric cancer. Laparoscopy-assisted total gastrectomy was planned for a 62-year-old male patient with a double early gastric cancer located in the upper and lower third of the stomach. Five trocars were placed and we used a harmonic scalpel to dissect the greater curvature. Enlarged splenic hilar lymph node was encountered and they were proved to be metastasis by frozen section biopsy. We then performed total gastrectomy with pancreas-preserving splenectomy for the purpose of completely dissecting the lymph nodes along the splenic artery and splenic hilum. We created a 4 cm sized longitudinal mini-laparotomy below the xiphoid process to remove the specimen, and anastomosis was done via the Roux-en-Y method. The patient was discharged on the 9th postoperative days after an uneventful recovery. Our experience shows that laparoscopy-assisted total gastrectomy with pancreas-preserving splenectomy is a relatively safe procedure for treating upper third early gastric cancer with metastatic splenic hilar lymph nodes.
