OBJECTIVE: To find out the changes of the plantar pressure distribution of foot and the pathway of center of pressure (COP) in normal preschool children with age. METHOD: Thirty-eight normal children aged 1 to 6 were participated in this study. We divided into three groups according to the age. Foot contact area, pressure of the foot and pathway of COP were measured using F-scan in-shoe measuring system (Tekscan Inc.) during the gait. RESULTS: The ratio of midfoot contact width to forefoot contact width was decreased with age (p<0.05). And the relative pressure of the medial midfoot was decreased with age (p<0.05). In the analysis of COP, the ratio of anteroposterior length of COP to total contact length was significantly increased (p<0.05), and the ratio of mediolateral width of COP to forefoot contact width was tend to decrease. CONCLUSION: We can identify the characteristics and changes of the foot pressure distribution and the pathway of COP in preschool children with normal foot using F-scan system. These quantitative data of foot scan are useful for evaluating the foot pathology in preschool children during the gait.

It is well known that the murine T helper cell clones are divided by their lymphokine secretory activities. One is the Th-1 cell, producing IL-2 and IFN after stimulation and the other is the Th-2 cell, producing the IL-4 and IL-5. This study was undertaken to evaluate the immunomodulatory properties of the bacterial lipopolysaccharide(LPS) on the lymphokine production in vivo and in vitro. The results were as follows: There were no effects on the lymphokine secretion by the in vitro treatment of the LPS. The in vivo treatment of the LPS decreases the capability of the production of IL-2 and IFN , whereas it increases the capability of IL-4 production. The altered capacity of the lymphokine production was recovered about 2 weeks after the treatment of the LPS. There were no differences on the lymphokine production between E-coli LPS and salmonella LPS. The capacity of the lymphokine production was the same in the treatment of a non-heated LPS or heated-LPS. The lymphokine production of the mice which were desensitized by the long term treatment of the LPS was not different from the control mice. The in vitro treatment of RU486 can block the alterations of the lymphokine production after the treatment of the LPS. In summary, one can tell that the LPS increases the secretion of the IL-4 through the endogenous secretion of the glucocorticoids.

PURPOSE: People with dementia have poor mobility and discharge outcomes following hip fractures. The purpose of this study was to evaluate the clinical and radiological results of internal fixation of undisplaced femur neck fractures (Garden types 1 and 2) by proximal femoral nail antirotation (PFNA) in dementia patients. MATERIALS AND METHODS: We studied retrospectively 19 patients with undisplaced femur neck fracture. All patients were over 70 years of age, walked independently with a cane or crutches and suffered moderate-to-severe dementia. Patients were treated with PFNA and followed-up for more than 2 years. Revision, loss of fixation, complications, and walking ability outcomes were measured. RESULTS: In walking-ability evaluation, patients showed an average decrease of just 0.2 points at the final follow-up. Walking ability was evaluated from before injury to 4 weeks after surgery and decreased by less than 0.5 points. Radiological bone union was achieved in 17 cases; the average time to bone union was 4.14 months (range, 2.5-7 months). Complications included non-union in two cases and femoral head avascular necrosis in one case of non-union. CONCLUSION: We found that for patients with osteoporotic bone tissues in their femoral heads or patients (e.g., those suffering dementia) for whom cooperating with medical workers for postoperative walking control or rehabilitation exercises is difficult, implanting a mechanically stable spiral blade for fixation of femoral neck fractures could facilitate walking after surgery.

PURPOSE: To compare the clinical and radiological results between internal fixation using the proximal femoral nail system and bipolar hemiarthroplasty (BHA) in reverse oblique intertrochanteric hip fractures in elderly patients. MATERIALS AND METHODS: From January 2005 to July 2012, we reviewed the medical records of 53 patients who had been treated surgically for reverse oblique intertrochanteric fracture and had been followed-up on for a minimum of two years. All patients were > or =70 years of age, and divided into two groups for retrospective evaluation. One group was treated with internal fixation using the proximal femoral nail system (31 cases), and the other group was treated with BHA (22 cases). RESULTS: Early ambulation postoperatively and less pain at postoperative three month were significantly superior in the BHA group. However, by 24 months postoperatively, the internal fixation group exhibited higher Harris scores and correspondingly less pain than the BHA group. There were no significant differences in union rate, duration of hospitalization or lateral wall fracture healing between the two groups. Four patients in the internal fixation group underwent reoperation. CONCLUSION: In the treatment of intertrochanteric fracture of the reverse oblique type, open reduction and internal fixation should be considered to be the better choice for patients with good health and bone quality. However, in cases of severe comminition of fracture and poor bone quality, BHA is an alternative offering advantages including early ambulation, less pain at early stages, and a lower risk of reoperation.

This research was conducted to investigate the responses of the patients and the therapists who attend the community meeting, to evaluate the therapeutic effects of community meeting as a group psychotherapy by applying short form scale of Yalom's Q-sort, to diagnose and complement the problems of the community meeting and to aim at activating the therapeutic function as the group psychotherapy The community meeting was held by 10 times during the stage of oscillation of the community and 26.7 patients group(+/-2.95) and 8.5 therapists group(+/-1.43) attended the every meeting. Consequently, both patients group and therapists group evaluate the community meeting as positive, and on the item which is helpful to them, while patient group responds it is 'mutual understanding and love' and 'self-understanding', therapist group does it is 'frank self-expression' and 'conversation'. On all items of group psychotherapy factors in the community meeting, the patients group evaluates it is more therapeutic in comparison with the therapists group, especially there is a significant difference in nine items such as 'altruism', 'group cohesiveness', 'interpersonal input', 'interpersonal output', 'identification', 'instillation of hope', 'family reenactment', 'self-understanding' and 'existential awareness'. In addition, on the therapeutic factor which is activated group psychotherapy factor in the community meeting, both patients and therapists respond that it is 'existential awareness' and 'universality', and they evaluate 'interpersonal output' as an non-activated therapeutic factor.

PURPOSE: Esophageal cancer patients have a difficulty in the intake of meals through the blocked esophageal lumen, which is caused by an ingrowth of cancer cells and largely influences on the prognosis. It is reported that esophageal cancer has a very low survival rate due to the lack of nourishment and immunity as the result of this. In this study a new radioactive stent, which prevents tumor ingrowth and restenosis by additional radiation treatment, has been developed. MATERIALS AND METHODS: Using HANARO research reactor, the radioactive stent assembly (166Ho-SA) was prepared by covering the metallic stent with a radioactive sleeve by means of a post-irradiation and pre-irradiation methods. RESULTS: Scanning electron microscopy and autoradiography exhibited that the distribution of 165/166Ho (NO3) compounds in polyurethane matrix was homogeneous. A geometrical model of the esophagus considering its structural properties, was developed for the computer simulation of energy deposition to the esophageal wall. The dose distributions of 166Ho-stent were calculated by means of the EGS4 code system. The sources are considered to be distributed uniformly on the surface in the form of a cylinder with a diameter of 20 mm and length of 40 mm. As an animal experiment, when radioactive stent developed in this study was inserted into the esophagus of a Mongrel dog, tissue destruction and widening of the esophageal lumen were observed. CONCLUSION: We have developed a new radioactive stent comprising of a radioactive tubular sleeve covering the metallic stent, which emits homogeneous radiation. If it is inserted into the blocked or narrowed lumen, it can lead to local destruction of the tumor due to irradiation effect with dilatation resulting from self-expansion of the metallic property. Accordingly, it is expected that restenosis esophageal lumen by the continuous ingrowth and infiltration of cancer after insertion of our radioactive stent will be decreased remarkably.

Coronary stent dislodgement during percutaneous coronary intervention, which occurs when the stent is passed through tortuous and calcified lesions, is not a rare complication. Without proper treatment, such as fixing with another stent in the coronary artery or removing the undeployed stent from the coronary artery or systemic artery system, this complication can cause serious problems. We experienced the unusual situation of a dismounted and dislodged coronary stent, in which retrograde retrieval to the radial artery was impossible during transradial coronary intervention. We report on use of a rendezvous and snare technique at the brachial artery level via femoral puncture, which resulted in resolution without surgery.

Background and Objectives:
The study reports on the clinical experience of repairing white-eyed orbital blow out fracture through a retrospective study of various incidences of white-eyed orbital blow out fracture that resulted in different treatment methods and outcomes.Subjects and Method A retrospective study was performed on 22 patients with white-eyed blowout fracture who underwent operation between March 2009 and June 2019 at our clinic. Patients were divided into 2 groups by age: 6 to 12 and 13 to 18. A review of medical records included demographic data, cause of injury, preoperative symptoms, trauma to operation time and surgical outcomes including improvement of postoperative ocular symptoms and complications.
Results:
The study population included 20 males and 2 female patients ranging from 6 to 18 years (mean, 14.2 years) of age. Fifteen of 21 patients with diplopia or limitation of eyeball movement showed a complete improvement of symptoms after surgery and 6 (28.5%) had remaining symptoms. One patient had no ocular symptom, but had oculocardiac reflex including nausea and vomiting. Two cases were re-operated due to adhesion of graft material. There was one sinus infection related to the implant.
Conclusion
This study shows that early reconstruction and release of incarcerated muscle within 5 days after trauma for white-eyed blowout fracture gives successful result that does not accompany major complications. All of the 22 patients who were operated for white-eyed blowout fractures had successful results.
