Purpose: To evaluate the clinical results and determine appropriate methods of surgical treatment about type II talar neck fracture. Materials and Methods: Among nineteen patients who received surgical treatment for type II talar neck fracture from May 2000 to May 2005. Fourteen patients with a follow-up period of more than 1 year were divided into two groups. Six patients reduced by closed reduction (Group A) with screw fixation and eight patients reduced by open reduction with screw fixation. We analyzed preoperative, postoperative and follow-up simple radiographs and reviewed patient hospital records retrospectively. Clinical results were evaluated by Hawkins scoring system. We analyzed pain, limp, range of motion of ankle and subtalar joint. Results: Five patients (83.3%) in group A and seven patients (87.7%) in group B had excellent and good clinical results. There were no complications including avascular necrosis, delayed union, nonunion. Conclusion: Closed reduction with screw fixation of talar neck fracture shows correct reduction and satisfactory results. But because of short term period of follow-up, we need long term results.

Cinereous vulture (Aegypius monachus) is a large raptor that belongs to the family Accipitridae in the order Falconiformes. It is a migratory bird that returns to Mongolia after wintering in the Korean Peninsula. In February 2015, a cinereous vulture was rescued from Asan-si, Chungcheongnam-do Province as it could not fly. It was transferred to the Chungnam Wild Animal Rescue Center in Korea. It was found to have a closed fracture on the right radius through radiographic examination, a basic procedure. Surgery was performed at the fracture site using a shuttle pin and wire. After successful physical therapy and rehabilitation, the cinereous vulture was released in October 2015. A metal ring (150-00713) and wing tags (G/BL 3) were attached to the bird before its release for subsequent identification. Two years and 4 months later, in March 2018, the cinereous vulture was rescued and brought back to the center. It was diagnosed with secondary pesticide poisoning. After receiving treatment, a radiography test revealed no specific findings related to the previous fracture surgery. Considering that migratory birds travel long distances, it was confirmed that the treatment for reducing the fracture in the radius using a shuttle pin and a cerclage wire was suitable.

Reexpansion of the lung is the most desirable method of filling the pleural space whether it`s contents may be, and closed thoracotomy connected to a water-seal drainage remains the basic therapeutic modality in the treatment of the problems of the pleural space. We usually used rubber mushroom tubes, size No. from 16 to 34 Fr., and performed closed thoracotomy after preliminary thoracentesis to determine the exact depending position. Author reviewed 576 cases of closed thoracotomy which were performed in the Department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital, since Jan., 1980 to June, 1984. The results were as follows: 1. The age distribution was 10 days to 76 years old and mean age of the patients was 36.6 year, and the most prevalent age group was twenties, and sex predisposition was male dominant, 86.9%. 2. The most common etiologic disease group was pneumothorax and the most common etiologic disease was traumatic hemothorax. 3. Sites of tubing were predominantly at posterior axillary line, 7th intercostal space and midclavicular line, 2nd intercostal space even though frequent presence of free pleural space. The two sides, right and left difference of occurrence rate was more frequent at right side, 51.2%. 4. Usually the durations of tubing was less than 10 days, 52.6%, and the number of tubes used to the same patient concomitantly was one, 73.9%, and the time of tubing to the same patient was 1st, 83.6%. 5. The common symptom and sign were dyspnea, 50.0%, chest pain, 30.7%, cough, 10.7%, fever, 6.5%. Especially, fever and cough was the most common symptom and sign in pyogenic empyema, 59.3%. 6. The common etiologic lesions of pneumothorax were blebs and bullae, 73.3%, and of pyogenic empyema was pneumonia, 69.0%. 7. The complication rate of closed thoracotomy was 26.0%. Among these complications, infection was 44.7%, and intercostal neuralgia was 25.3%. 8. 70.9% of all patients recovered with only closed thoracotomy and the rest of patient needed additional some necessary managements such as open thoracotomy [Blebectomy, Resection, Pleurodesis, Decortication, Bleeding control], open drainage, thoracoplasty and so on to have successful results.

PURPOSE: The aim of this study was to investigate the effect of closed and open kinetic exercises on knee extensor strength and balance in patients with early stroke. METHODS: Thirty patients with early stroke participated in the study. Participants were randomly assigned to three groups: an open kinetic chain (OKC) exercise group (n=10), a closed kinetic chain (CKC) exercise group (n=10), and a control group (n=10). All participants received conventional physical therapy for 30 minutes. In addition, the two experimental groups (OKC and CKC) participated in a 30-minute knee strengthening training program. Training for the experimental groups was carried out three times a week for four weeks. Outcomes such as knee extensor strength and balance ability (Tetrax, Functional Reaching Test, Timed Up and Go Test) were measured before and after training. RESULTS: There were significant differences in knee extensor strength and balance ability between the pre- and post-treatment of all groups (p<.05). The improvement of knee extensor strength was significantly higher in the OKC group than in the other groups (p<.05), and the improvement of dynamic balance was significantly higher in the CKC group than in the other groups (p<.05). CONCLUSION: These results showed that both open and closed kinetic chain exercises are effective in the improvement of knee extensor strength and balance ability. This study suggests that open and closed kinetic exercise training is an effective training for strength and balance in patients with early stroke.

The present study was performed to evaluate the function of the mandible according to the pattern of fracture and treatment methods of condylar fractures of the mandible and help operators in making a treatment plan. Sixty patients (average follow-up period was $7.8{\pm}9.4$ months) who were treated for condylar fracture from June, 2002 to May, 2006 at the Department of Oral and Maxillofacial surgery, Chonnam National University Hospital were reviewed. The common causes of the condylar fracture were traffic accident and fall-down (35.0%). In concomitant injuries, laceration was 46.7% and the fracture of the mandibular symphysis was highest incidence (60.0%). The common site of the fracture was the condylar head (47.8%), followed by subcondyle (36.2%) and condylar neck (15.9%). Under 15 years old patients, the closed reduction was performed in 87.5% out of the patients. All of the condylar fragments were fixed to the mandible with titanium miniplates in cases of open reduction. The mean period of intermaxillary fixation (IMF) was $14.2{\pm}6.5$ days in closed reduction and $10.0{\pm}4.2$ days in open reduction. The old patient with bilateral condylar head fractures, who were treated by closed reduction with IMF for 3 weeks, showed the limitation of mandibular movements. But, there was no significant different results between open reduction and closed reduction with the respect of the Helkimo's mandibular mobility index and clinical dysfunction index (DI). Complications, such as fibrous ankylosis and resorption of the mandibular condyle, were not observed in all patients. These results suggest that the good results can be obtained by closed reduction with proper IMF periods and functional exercise in most condylar fractures of the mandible except severely displaced extracapsular fractures.

As the adult population continues to increase, orthodontic treatment for adult patients is becoming more common. This case report describes comprehensive orthodontic treatment of a middle-aged patient with closure of the extraction space without prosthetic restoration. A 55-year-old woman with her maxillary left first premolar extracted because of a periodontal problem, wanted to close the space with orthodontic treatment. Since she had generalized crowding and mild skeletal discrepancy, we planned comprehensive orthodontic treatment, including closure of the extraction space by protraction of the left maxillary molars using miniscrews and aesthetic alignment of anterior teeth. The total treatment period was 28 months. As a result of these treatments, the extraction space was successfully closed, good tooth alignment and satisfactory occlusion were achieved.

Background: Closed reduction is the standard treatment for nasal bone fractures, which are the most common type of facial bone fractures. We investigated the effect of closed reduction on quality of life. Methods: The 15-dimensional health-related quality of life survey was administered to 120 patients who underwent closed reduction under general anesthesia for nasal bone fractures from February 2018 to December 2019, on both the day after surgery and 3 months after surgery. Three months postoperatively, the presence or absence of five nasal symptoms (nose obstruction, snoring, pain, nasal secretions, and aesthetic dissatisfaction) was also evaluated. Results: The quality of life items that showed significant changes between immediately after surgery and 3 months postoperatively were breathing, sleeping, speech, excretion, and discomfort. Low scores were found at 3 months for breathing, sleeping, and distress. There were 31 patients (25.83%) with nose obstruction, 25 (20.83%) with snoring, 12 (10.00%), with pain, 11 (9.17%) with nasal secretions, and 29 (24.17%) with aesthetic dissatisfaction. Conclusion: Closed reduction affected patients' quality of life, although most aspects improved significantly after 3 months. However, it was not possible to rule out deterioration of quality of life due to complications and dissatisfaction after surgery.

A 2-year-old male Tosa was admitted for treatment of a non-healing wound on the right forelimb. Skin tests were unremarkable; however, the lesion contained severe proliferative tissue. Surgical treatment was conducted due to the extensive skin defect and granulation tissue present. Following removal of the proliferative tissue, the wound was closed using the adjustable horizontal mattress suture method with multiple punctate relaxing incisions. The proliferative tissue healed completely after the surgical treatment. This technique can be considered an alternative treatment for the proliferative tissue when conditions require a skin graft or flap after surgical treatment.

The analytical treatment for a terminal cost problem of a distributed reactor with a small singular parameter is presented. The inverse of the neutron velocity is regarded as a singular parameter, and the model, adopted for simplicity, is a cylindrically symmetrical reactor. The Helmholtz mode expension is used for the application of the optimal theory for lumped parameter systems to the spatially distributed parameter system. The closed-form solution is explicitely obtained for machine calculation.
