Purpose: This study was performed for analysis of the results of polymerase chain reaction(PCR) and antibody test of Mycoplasma pneumoniae(M. pneumoniae) in children with symptoms of respiratory tract infection. In the cases of both positive antibody test and PCR for M. pneumoniae, the chest X-ray findings were assessed. Methods: The antibody test was done in 1,979 cases who have been admitted to Wonkwang university hospital department of pediatrics with symptoms of respiratory tract infection from January, 2000 to December, 2001. The positive antibody test was defined as titer of 1 : 80 and over 1 : 80. The PCR of M. pneumoniae were done in randomly selected 131 cases of respiratory tract infection. The chest X-ray findings were assessed in the cases of positive antibody test and PCR. Results: The numbers of cases of the positive antibody test for M. pneumoniae were 499 cases(25%). The PCR for M. pneumoniae were performed in 131 cases and the 45 cases(34%) were positive and 86 cases(66%) were negative. The 56 of 86 PCR negative cases were also negative antibody test, but 30 cases were positive antibody test. The 36 cases of 45 PCR positive cases were antibody positive, and 9 cases were antibody negative. The sputum Gram stain and culture for M. pneumoniae were negative in all the 499 cases of mycoplasma antibody positive respiratory infection. In these antibody positive 499 cases, the most common X-ray findings was interstitial pneumonic infiltration in 266 cases(53%), and pleural effusion were detected in 22 cases(4%), but nonspecific chest X-ray finding showed in 129 cases(26%). In PCR positive 45 cases, the most common chest X-ray finding was interstitial pneumonic infiltration in 32 cases(71%). Conclusion: The PCR for M. pneumoniae is more useful method for detection of mycoplasma infection in children with respiratory tract infection. The M. pneumoniae is a important etiologic agent for respiratory infection in children.

The hamartoma is the most common benign tumor of the lung, but the incidence is very low. Most of hamartomas are revealed accidentally as coin lesion of routine chest X-ray because of no symptoms usually. The differential diagnosis should include tuberculoma, bronchogenic carcinoma, and other forms of tumor. Definitive diagnosis usually is established at exploratory thoracotomy. In this report, we present one case of a 42-year-old female having hamartoma of the left lower lobe of the lung that removed successfully and confirmed histopathologically. Her postoperative course was uneventful. She was discharged in good condition.

Crytococcosis is a subacute or chronic, very rare in incidence and very often fatal infection caused by Cryptococcus Neoformans. The organism is of world-wide distribution, affecting both sexes and all ages. The most common portals of entry appear to be respiratory tract. Recently we experienced one case of isolated Cryptococcal Granuloma on the right lower lobe. The patient was 63 year old housewife, who complained only of epigastric pain. On baseline studies of chest X-ray, we incidentally found the abnormal finding of mass density on right lower lobe.

Between June 1981 and April 1994, 15 patients underwent surgical repair of diaphragmatic hernia. The ages ranged from 1 day to 60 years, with a mean age of 34. There were 5 cases of congenital diaphragmatic hernia; Bochdalek hernia in 4 cases and Morgagni hernia in 1 case. There were 10 cases of traumatic diaphragmatic hernia;blunt trauma in 8 cases and stab wounds in 2 cases. The chest X-ray findings were abnormal in 10 cases. Operations were performed in all patients and there was only one death, who was a newborn with left Bochdalek hernia and pulmonary hypoplasia.

Bilateral traumatic rupture of diaphragm is very rare. One case due to car accident is reported. Preoperative chest X-ray revealed the diaphragm rupture in the left side and the hemothorax in the right side. During the completion of left diaphragm repair through left thoracoabdominal incision, right diaphragm rupture was found incidentally. Left diaphragm was repaired using pledgets which were anchored at the thoracic wall. Right diaphragm was also repaired by interrupted Halsted sutures through seperated right thoracotomy. Postoperative course was uneventful.

We had operated 5 cases of residual ventricular septal defect after primary repair of isolated ventricular septal defect from 1975 to 1981. Three were male and two were female. Their ages ranged from 7 to 25 years old. In 4 cases previous patch was detached and one case had left ventricular - right atrium communication. They had had residual symptoms after primary operation and chest x-ray showed cardiomegaly. Cardiac catheterization was performed in all cases. Residual left to right shunt was more than 1.4: 1 with pulmonary hypertension. Their postoperative course were uneventful and long term follow up revealed that they were good health until one to 4 years.

Authors experienced a case of malignant melanoma of the mediastinum, At the time of first visit to the hospital, the female patient, aged 48, and had chief complaints of right shoulder pain that was radiated to its forearm and right Horner`s syndrome. In chest X-ray and CT, extrapulmonary circumscribed mass in the right apicomedial aspect of mediastinum was found. She had no nevus and no melanoma on entire skin area. We excised the tumor and confirmed it as malignant melanoma by histopathology.

Lipomas are common tumors occuring mostly in the skin and subcutaneous tissue. This tumors are rare in the thorax. They frequently represent on incidental roentgengraphic finding or symptomes depending primarily on their location and size. The patient was 23-month-old male complained of fever and coughing. His chest X-ray and CT scan were revealed soft tissue density featured of pleural mass in the left lower hemithorax. And thoracotomy was performed for accurate diagnosis and treatment. So, experience of parietal pleural lipoma is reported here in.

A 42-year old male was seen with symptoms of dysphagia, chest pain and dyspnea of 9 months duration. A benign tumor of the posterior mediastinum was diagnosed from x-ray studies and a transthoracic needle aspiration biopsy which was inconclusive. A left thoracotomy revealed a huge mass occupying the retrocardiac space and the contra-lateral mediastinum. It was resected by blunt dissection and, during this process, a 3.0 cm laceration was created in the esophageal wall. This was repaired with Tevdec sutures and staplers and was reinforced with an intercostal muscle flap to prevent leakage. The postoperative course was entirely uneventful.

The 50-year-old female patient was admitted to our hospital because of dysphagia and foreign body sensation on the neck after swallowing of solid foods 5 days ago. Esophagoscopic findings, performed on 2 days prior to admission, revealed no pathology. She had no history of preexisting esophageal disease. Under the diagnosis of the cervical esophageal perforation by routine studies such as simple chest, neck x-ray films and clinical findings, incision and drainage on the retropharyngeal space was done. Postoperatively we found the protruded degenerative spur on the 5th and 6th cervical vertebral bodies, and we considered that esophageal perforation in this case was predisposed by cervical spur. The postoperative course was uneventful.
