Purpose: This study aimed to compare a dynamic neuromuscular training program with a static neuromuscular training program for taekwondo players. Methods: This study design was a randomized control trial. Three high school taekwondo teams (taekwondo neuromuscular training [TNT] group, 22; Get Set group, 17; and control group, 24) participated in the study. Get Set group performed a program focused on the static movement, and TNT group performed a program which was modified Get Set to dynamic movement. Control group maintained the existing taekwondo training without any intervention. The intervention group performed 15-minute training three times a week for 6 weeks. Dynamic Postural Stability Index (DPSI) and time-to-boundary test (TTB) tests were performed before and after 6 weeks of training. Results: As a result of DPSI, an interaction effect was observed only in the anterior/posterior stability index of the dominant leg of the TNT and Get Set groups (p＜0.05). However, there was no difference between the TNT and the Get Set groups.As a result of TTB analysis, no statistical effect was observed in all variables of the dominant and non-dominant legs. Conclusion As a result of conducting 6-week dynamic and static neuromuscular training for taekwondo athletes, the effect of training was found in both the intervention group. However, differences in training effects between groups could not be proved. Therefore, it is necessary to clearly confirm the difference between the two training through long-term follow-up studies.

BACKGROUND: The growing number of spinal cord injured individuals facing old age makes the understanding of age related limitations increasingly important. This study was to investigate the age-related differences in rehabilitation outcome according to the level of cervical spinal cord injury and each category of activity of daily living(ADL). METHODS: Subjects were 79 adults with tetraplegia all of whom were admitted in National Rehabilitation Hospital. The level of injury was classified into upper cervical(C4, C5), mid-cervical(C6), and lower cervical(C7, C8) spinal cord injury. Eight ADL categories including feeding, grooming, bathing, dressing, toileting, bed-transfer, toilet/tub transfer, and indoor mobility were assessed using the scale of Spinal Cord Independence Measure. Age related differences were examined by separating the sample into two age groups(> or =40 and <40 years) RESULTS: There was no age related difference in rehabilitation outcome in upper cervical cord injury patients. In mid-cervical cord injury level, ADL capacities differed only in the feeding and grooming activities. In lower cervical cord injury level, older patients showed lower rehabilitation outcome than younger counterparts in all ADL categories examined. CONCLUSION: Along with injury level, age should be considered when formulating rehabilitation plans and functional prognostic statements in tetraplegic patients.

PURPOSE: We investigated the effect on MK 801 on the development on brain damage, spontaneous recurrent seizures and mossy fiber sprouting in the pilocarpine induced status epilepticus animal model. Methods: Fifty two adult Sprague Dawley male rats(180-240gm) were studied under ketamine/xylazine(87mg/13mg/kg, IP) anesthesia and were implanted at the F3, P3, F4, P4 areas for recording EEG. With a single intraperitoneal(IP) administration of pilocarpine hydrochloride(360mg/kg), 70% developed status epilepticus(SE). When SE was not induced within 1 hour after injection of pilocarpine, the second dose of pilocarpine(175mg/kg, IP) was injected, with 86.6% of success. Results: All studied animals were divided into two large groups, one group was treated with NMDA receptor antagonist, the other was control group. The mean duration of SE was 62.00+/-6.80 minutes in the MK 801(1mg/kg, IP, 30 minutes after SE) treated group, and 61.10+/-7.37 minutes in the control group without any signigicant differences(P>0.05). Neuronal loss(necrosis dominantly) was observed at CA1 and CA3 areas in the control group, with more loss after 6 weeks than 24 or 72 hrs specimens. However, there was no neuronal loss in MK 801 treated group. The protective effect of MK 801 for neuronal injury suggested the glutamate receptor activation was involved in the neuronal injury induced by repeated seizure attack. Spontaneous recurrent seizures(SRS) were observed 70% of animals in the control group, but there were no SRS observed in the MK 801 treated group. The mean scores of mossy fiber sprouting were significantly higher in the control group(2.05+/-0.47) than MK 801 treated group(0.4+/-0.32)(P<0.05). Conclusion: These results suggested that SRS and mossy fiber sprouting were associated with NMDA receptor activation, and NMDA receptor activation had a key role in the epilepsy development.

Objective: Emergency physicians frequently encounter suicidal attempt patients. Some of the patients are intoxicated with the pesticides. Unlike medical drugs, finding out detailed information in terms of human toxicity is not easy. In Korea, there is the crop protection substance guidebook, and the toxicity grade is noted in that book. However, little is known about the patients’ characteristics and outcomes with slightly hazardous substances. Methods: This is a retrospective, single-center study. The study duration was 2 years. We investigated the pesticideintoxicated patients who visited our emergency department. The patients were divided according to toxicity grades, including slightly hazardous, moderately hazardous, highly hazardous and extremely hazardous. Initial vital signs, mental status, laboratory values, therapeutic modalities and therapeutic outcomes were investigated. Results: Among a total of 472 patients, 110 (23.3%) were pesticide-intoxicated patients. Intensive care unit (ICU) admission rate and mortality rate were higher, and ICU admission duration was longer in the pesticide-intoxicated patients. The deterioration of initial arterial blood gas values (41.2%), hypokalemia or hyperkalemia (32.4%), acute kidney injury (17.6%), troponin elevation (8.8%), and rhabdomyolysis (3.4%) were noted in the slightly hazardous group. Continuous renal replacement therapy, endotracheal intubation and vasopressor use were performed in some of them. The seizure, shock and cardiac arrest were also developed. More than half of patients (52.9%) were admitted to the ICU. Conclusion Significant limitation of relying on the toxicity grade was noted. In the low-grade toxicity pesticide group, some patients were deteriorated. Therefore, caution is needed when treating pesticide intoxication patients.

The aim of this study was to compare the quality of life (QoL) depending on the postoperative survival period or nutritional status in gastric cancer patients. Surviving gastric cancer patients (n = 222) after the gastrectomy were included in the study at Soonchunhyang University Bucheon Hospital from April 2010 to August 2012. The Korean versions of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30) and a gastric cancer-specific module, the EORTC QLQ-STO22, were used to assess the QoL. The postoperative survival period of the patients fell into two groups; the less-than-1-year group or the more-than-1-year group, and the nutritional status of the patients fell into three groups by a score of patient generated-subjective global assessment (SGA)-A, B, and C. As a result, the rate of malnutrition was 34.5% in the less-than-1-year group and 19.8% in the more-than-1-year group, respectively. Score for the fatigue (p = 0.006), loss of appetite (p = 0.002), reflux (p = 0.027) and body image (p = 0.004) in which the QoL was significantly lower in the less-than-1-year group than in the more-than-1-year group. The score of QoL according to the nutritional status of all subjects, overall health status (p = 0.043), physical functioning (p = 0.016), fatigue (p = 0.006), pain (p = 0.028), loss of appetite (p = 0.017), reflux (p = 0.003), eating restriction (p = 0.002), anxiety (p = 0.010), and body image (p = 0.001) was significantly lower in the SGA-C group than in other SGA groups. These results suggest that the nutritional status of the gastrectomy patients with stomach cancer may impact on their QoL. It is necessary to to develop nutritional intervention to improve QoL in gastric cancer patients with postoperative malnutrition.

PURPOSE: To retrospectively evaluate the relationship between the vertical position of the implant-abutment interface and marginal bone loss over 3 years using radiological analysis. METHODS: In total, 286 implant surfaces of 143 implants from 61 patients were analyzed. Panoramic radiographic images were taken immediately after implant installation and at 6, 12, and 36 months after loading. The implants were classified into 3 groups based on the vertical position of the implant-abutment interface: group A (above bone level), group B (at bone level), and group C (below bone level). The radiographs were analyzed by a single examiner. RESULTS: Changes in marginal bone levels of 0.99±1.45, 1.13±0.91, and 1.76±0.78 mm were observed at 36 months after loading in groups A, B, and C, respectively, and bone loss was significantly greater in group C than in groups A and B. CONCLUSIONS: The vertical position of the implant-abutment interface may affect marginal bone level change. Marginal bone loss was significantly greater in cases where the implant-abutment interface was positioned below the marginal bone. Further long-term study is required to validate our results.

PURPOSE: The purpose of this study was to evaluate the clinical and radiological results of revision total hip arthroplasty using modular distal fixation stems for proximal femoral deficiency. MATERIALS AND METHODS: Forty-five patients (47 hips) were analyzed more than 24 months after revision total hip arthroplasty that used modular distal fixation stems and was performed between 2006 and 2012. There were proximal femoral defects in all cases. Preoperative femoral defect classification revealed Paprosky type II in 31 cases, type IIIA in 7, and type IIIB in 9. The mean duration of follow-up was 53.4 (25-100) months. We evaluated the Harris hip score (HHS), walking ability according to Koval as clinical parameters, stem stability, and stem position change as radiographic parameters. Kaplan-Meier survival analysis was performed. RESULTS: The average HHS improved form 39.5 points to 91.3 points and walking ability also improved in most cases; all patients had stable fixation of the femoral stem. Postoperative complications included 5 cases of infection and 2 cases of dislocation. The survival rate with the end point of re-revision surgery due to infection or dislocation was 86% after 8-year follow-up. CONCLUSION: Cementless revision total hip arthroplasty using modular femoral stems is useful because the stems can be stably fixed on the diaphyseal portion of the femur, which has relatively good bone quality at mid-term follow-up.

As the incidence of early gastric cancer increases, laparoscopic surgery has become one of the treatments of choice for gastric cancer. With the increase of laparoscopic surgery, the chance of discovering aberrant anatomy during the operation also increases. We present a case of laparoscopic total gastrectomy in gastric cancer patients with intestinal malrotation. Intestinal malrotation occurs in one in every 500 births. We found that laparoscopic total gastrectomy in such patients can be performed successfully when it is performed with a proper Roux limb orientation through an alternative minilaparotomy.
