In diabetics, the frozen shoulder has been difficult to treat. They tend to respond poorly to manipulation. In this report we present the rationale and results of arthroscopic selective capsular release for those patients. Nine patients, who were diabetics, developed frozen shoulders which failed to respond to conservative management. They had persistent pain, stiffness, and limited function. An arthroscopic release was performed by progressively releasing the anterior structures from superior to inferior. Postoperatively physiotherapy was carried out daily to maintain the range of movement. At a follow up of 12 to 37 months the patients were assessed using the American Shoulder Society scheme. In addition, the patients were assessed preoperatively and postoperatively on four criteria: pain, external rotation, abduction and function. We found that the patients were statistically significantly improved in all four categories. Three of the nine patients had no pain, full range of motion compared with the opposite side and full function. There was one poor result of no improvement. The remaining five patients had improved but still had residual abnormalities. We consider arthroscopic release to be an effective treatment for the resistant diabetic frozen shoulder.

Salivary glands, major and minor, are susceptible to a wide variety of pathologic conditions. Excision of the submandibular gland is a surgical procedure often undertaken. The procedure is the treatment of choice for patients with neoplasm of the submandibular gland and those with non-neoplastic submandibular disorders which are not controlled with conservative medical measures. Extirpation of the submandibular gland may also be undertaken for diagnostic purposes. We evaluated 84 patients who had been admitted to the dept. of oral and maxillofacial surgery of Pusan National University Hospital from January, 1989 to December, 2002 and had been performed submandibular gland excision. The results are as follows : 1. The patients undertaken the excision of the submandibular gland showed an age range of 16 to 71 years. The average was 49.1. 2. They consisted of 60 males(71.4%) and 24 females(28.6%), having 2.5 : 1 of genda ratio. 3. The most common symptom was swelling in 41 cases(48.8%), followed by the pain in 23 cases(27.4%). Other symptoms included mass, dysphagia, facial abnormaly and neck dyscinesia. 4. 42 cases(50.0%) showed sialadenitis and sialodochitis associated with salivary calculus. 5. According to the histopathologic study, all cases consisted of 17 neoplasmatic conditions(20.3%) and 67 non-neoplasmatic(79.7%). The neoplasmatic cases included 13 benign tumors and 4 primary malignant tumors. Sialadenitis and sialodochitis associated with or without salivary calculus were most marked, found in 50 cases(59.3%), in the non-neoplasmatic conditions. Pleoomorphic adenoma showed the highest frequency of the benign tumor.

Obstructive adenitis of the salivary gland following salivary stone or infectious disease of the gland and surrounding tissues is a common disease. It is often difficult to decide whether to perform total excision of the gland or to consider conservative treatment. The present study was designed to investigate histological, histochemical changes of submandibular gland after ligating the excretory duct for identifying the results of gland duct obstruction. A group of 40 rat of Sprague-Dawley weighing about $200{\sim}220gm$ were used in the present study. 30 rats had ligation of the main excretory ducts of submandibular glands just at the exit from the glands. For controls, 10 rats had a sham operation without duct ligation. They were inducted into euthanagia state by intracardial Ketamine injection in 1, 2, 3, 5, 7, 14, 21, 28, 35 and 42 days after the ligation. In each ligation period, 3 animals were used for ligation and one animal was for control. The submandibular glands were dissected out at sacrifice and stained with H&E, PAS, mucicarmine stain and histological examination were carried out under the light microscope. After examination and comparison of all specimens, the results were as follows: 1. In the features of H&E stain, acini disappeared by degrees after the ligation of the excretary duct and interstitial cells were displaced into fibrous connective tissue. Salivary gland had been atrophied with enlarging ducts and proliferating ductal cells. 2. Through total experimental period, a lot of vessels were observed and the atrophy of serous gland was severer than that of mucous gland. 3. The deep portion of submandibular glands showed severe degeneration rather than superficial portion of them after the ligation. 4. The changes which had enlarged ducts and proliferating ductal cells were observed in entire gland and more prominent in serous gland than mucous gland after the ligation. 5. Although PAS and mucicarmine reactions were decreased gradually after the ligation with the lapse of time, since 2 to 3 weeks they were strong positive reactions on entire gland, especially on duct-like structure. So, we can suggest that salivary gland will be atrophied but, survived acini will be redistributed around the ducts.

Purpose: The wound of a patient who has chronic venous insufficiency is easy to recur. Also they develop a complication even after the conservative therapy or skin graft. We have to diagnose the venous stasis ulcer correctly and remove the cause to improve the effectiveness of treatment. We operated endoscopic perforating vein ligation and splitt thickness skin graft on a patient with venous stasis ulceration on right leg. Methods: A 26 year old male patient who had a scalding burn on his right leg in July 2005 checked into our hospital in March 2008. Even though he got three operations - the split thickness skin graft - at different clinics, the wound did not heal. The size of the wound was 12 by $8cm^2$ and granulation with edema and fibrosis had been formed. We kept observation on many collateral vessels and perforating vein through venogram and doppler sonography and firmly get to know that the wound came with chronic venous insufficiency. After a debridement and an application of VAC$^{(R)}$ for two weeks, the condition of granulation got better. So we proceeded with the operation using subfascial endoscopic perforating surgery and split thickness skin graft. Results: Through the venogram after the operation, we found out that the collateral vessels had been reduced compared to the previous condition and the widened perforating vein disappeared. During a follow up of 6 months, the patient did not develop recurrent stasis ulcer and postoperative complications. Conclusion: Subfascial endoscopic perforator ligation is relatively simple technique with a low complication rate and recurrence rate. Split thickness skin graft with subfascial endoscopic perforator surgery can be valuable method for treating severe venous stasis ulcers.

Purpose: The aim of this study is to investigate the change in incidence and clinical characteristics of acute poststreptococcal glomerulonephritis (APSGN) through a single center's experience. Methods: We retrospectively analyzed the medical records of 53 children who were diagnosed with glomerular nephritis at National Health Insurance Corporation Ilsan Hospital between March 2000 and December 2009. Twenty-six of 53 patients falled to meet the dragnostic criteria of APSGN and were excluded. Chief complaints, physical examinations, urinalysis, urine culture, laboratory results, chest x-ray, and clinical manifestations were all retrieved from the remaining 27 patients. Results: The incidence of APSGN by age was highest in children between six to seven years of age, with similar distributions in both genders, and seasonal incidence was higher from November to February when compared to other months, which was similar to the previously reported studies. However, the annual number of APSGN patients did not show a significant decrease from 2000 to 2009. The incidences of edema and hypertension were 59.3% and 48.1% respectively, suggesting lower incidences than those from previous studies. Six patients (22.2%) experienced hematuria for more than 6 months. Hypertensive encephalopathy, one of APSGN critical complications occurred in one patient but resolved with conservative treatment. Conclusion: Our study shows that APSGN still occur as a common renal disease but the disease severity seems to decrease with milder clinical manifestations and less complications compared to past studies.

Background: There are various tracheal diseseas which cause the obstruction of the trachea: postintubation tracheal stenosis, tracheal cancer, thyroid cancer, endotracheal tuberculosis, et al. Recently surgical resection and reconstruction of the trachea has been adopted as the safe method for tracheal lesions. Materials and methods: We report our experience and results of resection and reconstruction for various obstructive tracheal lesions in 38cases from 1985 to 1996. Length of resection of the trachea was up to 6 cm. Twenty lesions were approached by cervical collar incision, 12 lesions by cervicosternal incision and 4cases needed transthoracic approach. Surgical procedures consisted of resection and tracheotracheal anastomosis in 32 cases, resection and laryngotracheal anastomosis in 6cases and in addition laryngeal release was necessary to release anastomotic tension in 3cases. Results: The complications were 4 minor wound infections, 2 mild suture line granulomas, 1 vocal cord palsy, 2 pneumonias and 1 systemic candidiasis. Two patients who had poor consciousness and pnemonia and one who developed systemic candidiasis were expired after operation. Conclusion: We suggests resection and reconstruction of trachea is optimal procedure for up to 6cm long tracheal lesions. However, for the patients with poor consciousness or poor general conditions would be the conservative treatment preferred to the tracheal reconstruction because of high serious complications and mortalities.

Background: Multiple trauma patients have rapidly increased due to traffic accidents, industrial disasters, incidental accidents, and violence. Multiple trauma can involve injuries to the heart, lung, and great vessels and influence the lives, necessitate prompt diagnosis and treatment. Most of the thoracic injuries can be managed with conservative method and simple surgical procedures, such as closed thoracostomy, but in certain cases open thoracotomy is necessary. Materials and methods: The author analyzed the surgical result of 70 cases of open thoracotomy after multiple organ injury including thoracic organ. Results: The most common type of thoracic lesion was hemothorax with or without pneumothorax and diaphragmatic rupture was the second. Sixty percent of the patients were associated with bone fractures, 42.9% with abdominal injuries, and 37.1% with head injuries. The modes of operation were ligations of torn vessels for bleeding control(48.6%), repair of diaphragm(35.7%), and repair of lung laceration(25.7%) in this order of frequency and additional procedures were splenectomy(14.3%), hepatic lobectomy (8.6%) and repair of liver lacerations(5.7%). Postoperative complications were atelectasis (8.6%), wound infection (8.6%), and pneumonia(4.3%). Postoperatively six patients died(The mortality rate was 8.6%) and the causes of death were respiratory failure(2), acute renal failure(2), sepsis(1), and hypovolemic shock(1).

A clinical evaluation was performed on 305 cases of chest trauma experienced at the department of the Thoracic and Cardiovascular Surgery, Dae Jeon Eul Ji Hospital, during the period from March 1991 to November 1994. Age distribution was from 4 to 85 years, the mosts common age groups were 4-th, 5th and 6th decades. The ratio of male to female was 229:76(3:1), the ratio showed male predominance, the most common cause of trauma was traffic accidents in nonpenetrating trauma and stab wounds in penetrating trauma. Hemothorax, pneumothorax, and hemopneumothorax were observed in 159 cases (52.1 %) of total cases, Rib fracture was observed in 236 cases (77.4%) of total cases, location distribution was right : left : Both (102 : 142 : 45), with left predominant, rib fracture commonly involved from the 3th to 8th rib. Lag period from accident to admission was 155 cases (50.8%) under 6hr The principles of therapy for early complications of chest trauma were rapid r expansion of the lungs by thoracentesis 5 cases(1.6%) and closed thoracostomy 1-42 cases(46.6%), but open thoracotomy had to be done on 17 cases (5.6%) because of massive bleeding 13 cases or ruptured diaphragm, foreign body. Conservative nonoperative treatment was 140 cases (45.9%). Overall mortality rate was Bcases (2.6%) and common causes of the death were respiratory insufficiency and shock.

A 16-year-old female Shih-Tzu, weighing 5 kg, presented with clinical symptoms of abdominal distension and urinary and fecal incontinence. Abdominal palpation detected a large mass. According to the radiographic findings, the bladder had been moved to the umbilicus by the mass and a large abdominal mass was confirmed in the lower abdominal area. Ultrasonography indentified a large heterogeneous mass with heterogeneous parenchyma and a focal anechoic area in the lower abdominal area. The complete blood count abnormalities suggested thrombocytosis and mild neutrophilia, and the serum chemistry indicated an elevated alkaline phosphatase value. During laparotomy, a firm mass that measured $10.5{\times}9.6cm$ was found between the uterine cervix and urinary bladder. The urethra was embedded in the mass. A diagnosis of leiomyosarcoma was established based on histopathology and histochemistry. One week after surgery, urinary retention symptoms that did not appear to be related to mechanical obstruction presented suddenly, but they did not respond to several drug treatments, thus long-term conservative therapy was adopted. The urinary symptoms disappeared on day 27 and the patient started to void large quantities of urine in a smooth and frequent manner. This case report describes the serial changes in the patient's status and the response after surgical remove of the urethra embedding leiomyosarcoma.

Odontoma is the most common benign odontogenic tumors, and have been defined as mixed odontogenic tumor composed of epithelial and mesenchymal cells. Odontoma is believed to be hamartomatous rather than neoplastic in nature. The classification by WHO divides odontoma into 2 groups such as complex odontoma and compound odontoma. Compound odontoma comprises dental tissues, resembling the morphology of a tooth and has predilection for the anterior maxilla. In contrast, complex odontoma has unorganized mass, not resembling the normal tooth and has predilection for the posterior mandible. Odontoma is almost asymptomatic, so it is usually found on routine radiographic examination. Common presenting symptom is impacted or unerupted permanent teeth and retained primary teeth, but coexistent odontoma and congenital missing of permanent teeth is a very rare condition. The recommended treatment for an odontoma is conservative surgical excision, with care taken to remove the surrounding soft tissue. This report presents 2 patients with compound odontoma of the mandible who have congenital missing of the permanent teeth.
