Ovarian cysts are the most common cystic abdominal masses in female newborns. It is believed to be derived from an overstimulation of the ovarian follicles by maternal, placental, and fetal hormones. Although most ovarian cysts resolve spontaneously, surgical management is mandatory for life-threatening, complicated cases, including torsion, intracystic hemorrhage, and rupture of the cyst. Rupture of ovarian cysts is thought to be exceedingly rare, but can lead to severe hemorrhagic ascites or peritonitis. We managed a case of a ruptured ovarian cyst in a female newborn who presented with mild abdominal distension and two episodes of gross hematuria. Exploratory laparotomy revealed a right ovarian cyst with torsion and rupture. She was successfully treated with a right salpingo- oophorectomy with no sequelae.

Background: Spontaneous hemopneumothorax, occurring in 1% to 12% of patients with spontaneous pneumothorax, is a rare disorder that can potentially lead to life-threatening complications. Materials and methods: We have experienced 15 cases (2.28%) with spontaneous hemopneumothorax among 659 episodes of spontaneous pneumothorax for eight years, from 1990 to 1997, at our hospital. We studied our previously treated patients by retrospective case studies to determine the nature of optimal management. Results: There were 14 male and 1 female patients whose mean age was 27.5 years, ranging from 19 to 58. The sides with disorder were as following: right in 10 cases and left in 5, unilaterally. The amount of initial bleeding ranged from 400 to 1,500 mL and 8 patients received a homologous blood transfusion. Patients exhibited symptoms of chest pain, dyspnea, chest discomfort, and hypovolemic shock. We concluded that causes of this disease in our patients were a torn pleural adhesion (14 cases) and a rupture of vascularized bullae (1 case with an underlying intrinsic lung disease, tuberculosis). All patients underwent closed thoracostomy and had good results except for 3. One patient underwent thoracotomy within 3 days from the onset because of continuous active hemorrhage. Decortication was required in one case because of a reactive fluid collection in the pleural space, which led to impaired lung expansion. Another patient underwent thoracotomy due to a ipsilateral recurrent pneumothorax without blood collection. Conclusions: The goals of treatment include hemostasis and reexpansion of the collapsed lung. Thus, if patients arrive early at hospital, closed thoracostomy and transfusion are thought to be sufficient treatments, although early surgical repair has been considered recently.

Surgical correction of patent ductus arteriosus is,under most circumstances,highly successful and carries a low mortality. But infected PDA is yet potentially dangerous due to its frequent recurrence and resistant organisms to antibiotics. And,in surgical correction,surgeon may face the possibility of tearing of ductus arteriosus arterial end due to friability and adhesion of its surrounding tissue.This report demonstrats another problem in treatment of infected patent ductus arteriosus.This thirteen years old female patient received susceptible combined antibiotics intravenously from the day of admission and remitted from 4th.week of therapy.This remission state continued for 12days without relapse.But the pulmonary artery ruptured in this remission period.In autopsy,bacteria was not found in ductal vegetation.Also,there was no pulmonary artery aneurysm,Our experience show that in infected PDA,pulmonary artery can rupture spontaneously during remission period without aneurysmal formation.

Acute traumatic shoulder injuries related to motor vehicle accidents and industrial accident has shown a steep increase recently. In regard to the causal relationship and the previous illness, the rotator cuff tear and SLAP lesion are the mostly debated among shoulder injuries related to trauma. Both the possibility of spontaneous occurrence related to their degenerative etiology and the discordance between the extent of injury and the symptom of the rotator cuff tear and SLAP lesion, make it difficult and obscure to estimate the extent of involvement of accident. Therefore, the Insurance Committee of Korean Shoulder and Elbow Society performed a questionnaire for the shoulder specialists to investigate their criteria about deciding the treatment modalities and SLAP lesion and reviewed literatures regarding the causal relationship between the accident and the rotator cuff tear and SLAP lesion. The committee recommended the diagnostic criteria to judge contribution of the accident on traumatic shoulder injuries, and to offer a guideline for disabilities.

Mediastinal teratomas are rare and represent less than 10 per cent of all mediastinal tumors. Almost all arise in the anterosuperior mediastinal compartment, and most symptoms, when present, result from compression of adjacent structures. They contain different tissues derived from all three germinal layers, with the prevalence of ectodermal elements which can include hair, teeth and sebaceous material. Benign teratomas may rupture into adjacent organs. Up to 36% of all mediastinal teratomas rupture, most frequently into the lung and bronchial tree, followed by the pleural space, pericardial space, or great vessels. The signs and symptoms of a ruptured teratoma vary with the structures involved. We report a case of mediastinal teratoma ruptured spontaneously in a 18 year old female who experienced 4 or 5 times of hemoptysis for 1 year and sudden onset of pleural effusion, pericardial effusion and pneumonia.

The objective of the PKL III A 4.4 experiment is to examine that the plant could be controlled by manually operative actions "after Steam Generator Tube Rupture under Offsite Power Available without Safety Injection". In order to verify the limitation and ability of the system code NLOOP in the expeiment simulation, the behaviors of the PKL III facility obtained in the experiment are compared with the results of NLOOP code. NLOOP code, which is originally developed to simulate the transients of the Westinghouse type PWRs by KAERI/SIEMENS, modified properly to simulate the PKL III facility. Particular attention is given to the RCS mass How rate of the natural circulation in loops and the termination behavior of the natural circulation in the isolated loop. The comparisons between the experimental and calculational results show the simulation ability and problems of the code. the code.

Patients with mediastinal teratoma are usually asymptomatic, but may develop symptoms by rupture into adjacent structures which result in pneumonia, hemoptysis, pleural effusion, pericardial effusion, or pneumothorax. Rarely, life-threatening acute respiratory distress require a emergency surgery. Rupture into pleural cavity may result in pleuritis and pleural effusion with severe anterior chest or back pain. The symptom must be differentiated from other common intrathoracic distress diseases. Clinical, cytologic and radiologic examinations of pleural effusion, and moreover, measurement of enzymes such as amylase or insulin, which is secreted from pancreatic tissues, in pleural effusion and cystic fluid enabled us to make the diagnosis of rupture of mediastinal teratoma preoperatively.

Purpose : To analyze changes of the anterior translation, MRI findings and associated injuries at scarring of the torn ACL in the chronic ACL rupture. Materials & Method : From Dec. 1996 to May 2000, 19 patients who were diagnosed as the chronic ACL rupture were studied. We analyzed KT-2000 side to side difference of maximal manual anterior displacement(MMAD), MRI findings and associated injuries. Results : There was statistically significant difference in the average MMAD between the 7 cases$(37\%)$ with scar formation$(2.78{\pm}2.41mm)$ and the 12 cases without scarring$(5.75{\pm}2.52mm)$. The chronic ACL rupture without scarring had more meniscal injuries$(67\%)$ than with scarring$(28\%)$. MRI showed that relatively straight bands toward expected insertion site with single large fragment(5 cases) and continuous band with focal angulation(2 cases). Conclusion : If relatively straight bands toward expected insertion site with single large fragment or continuous band with focal angulation on MR imaging is showed in the patient without significant anterior translation at arthrometer, the possibility of the scar formation of the torn ACL should be considered. We think that the chronic ACL rupture with scarring had less meniscal injuries than without scarring will give additional information on the natural history of ACL injuries.

A rare case of acute descending necrotizing mediastinitis(DNM) secondary to spontaneous rupture of hypopharynx is reported. Due to the right lower cervical abscess the patient had undertaken limited right anterior cervical drainage at other department. After transferring to our department he undertook combined wide cervical mediastinal drainage and mediastinal drainage via right thoracotomy. However mediastinal drainage was ineffective. So the second operation was performed and chest tubes were relocated. He had an uneventful postoperative course. As far as the cause of acute descending necrotizing mediastinitis was concerned, we couldn't find any literature in Korean or English except one case that dealt with spontaneous rupture of the hypopharynx.
