Angiosarcomas are rare tumors, seen most commonly in the skin and soft tissue of head and neck region. But it has been described in numerous body sites including thyroid, breast, liver, spleen, bone, etc.. Their biological behaviors depend on the microscopic grade, site of origin, and multifocality. We report the unique cytological features of an angiosarcoma in pleural fluid. A 61-year-old woman presented with a 6 month history of dyspnea on exertion and chest pain. Chest computerized tomography(CT) revealed multiple subpleural small nodules in the right lung and widespread air space consolidation and pleural effusion in the left lung. CT of liver revealed multiple small low attenuated lesion. The smears obtained from pleural fluid showed hypocellularity with a hemorrhagic background. The tumor cells were highly pleomorphic oval or spindle in shape and presented singly, in loose groups, in knitted syncytial aggregates, and in acinar pattern. Their nuclei had vesicular chromatin with delineated, thick nuclear membranes and occasionally a large eosinophilic, prominent nucleolus. The cytoplasm was plump, thin or projected in spindly fashion. Almost all tumor cells showed variable sized intracytoplasmic vacuoles and their nuclei were sometimes crescentic by a huge vacuole. Occasional binucleated tumor cells and mitotic figures were present. Cellular debris and streaky materials were identified. Needle biopsy specimen from the pleura revealed anastomosing slit-like spaces lined by pleomorphic tumor cells. The tumor cells showed a strong reactivity for CD31 and vimentin and focal weak reactivity for factor VIII-related antigen.

Myotonic dystrophy is the most common systemic disease causing myotonia. We report the case of respiratory failure in a patient with myotonic dystrophy after laparoscopic cholecystectomy. We carried out neurologic testing, electromyography and DNA testing in this patient and electromyography in the family of the patient. Through electromyography and DNA testing, this patient was diagnosed with myotonic dystrophy type I. Myotonic dystrophy is characterized by gradual decline of muscle tone and myotonia. It is important that this disease be excluded through preoperative history taking, physical examination and family history taking.

Intraabdominal abscess usually causes distress with fever, leukocytosis, pain and toxicity. Diagnosis of intraabdominal abscess is occasionally difficult and it has high morbidity. However radiologic method, such as ultrasonography, CT scan, or RI scan are helpful to early detection of intraabdominal abscess. Among these methods, ultrasonography is a noninvasive technique and performed without discomfort to patient. And also differential diagnosis between cystic and solid lesion is very easy and sequential ultrasonography in same patient is valuable for the evaluation of treatment effect. We analyzed the ultrasonic features of 48 cases with intraabdominal abscesses and the results are as follows; 1. In total 48 cases, the intraabdominal abscesses were 30 cases, the retroperitoneal abscesses, 5 cases, and the visceral abscesses, 13 cases. 2. The causes of the intraabdominal abscesses were perforating appendicitis (25 cases), postoperative complications (5 cases), pyogenic and amebic hepatic abscesses (13 cases), and the other (5 cases). 3. Round or oval shaped lesions were 26 cases (54%), irregular shape, 18 cases (38%), and multiple abscess formation in 4 cases (8%). 4. The size of the lesions were between 5 and 10cm in diameter in 54% of total 48 cases, and the most frequent feature of the echo pattern of the lesions was cystic with or without internal echogenicity (69%).

The authors report a case of monostotic eosinophilic granuloma which occured in the skull. A 37 year-old woman was presented with headache and soft mass in the occipital region. Plain skull X-ray showed a "punched out" osteolytic lesion in the right paramedian posterior parietal bone. Computed tomography shows a soft tissue mass and irregular bone destruction in corresponding region. On magnetic resonance image, the mass was of high signal intensity, with subgaleal extension and looks like a shirt stud or "collar button" on T2-weighted image. Total excision of the tumor and postoperative radiotherapy(1000cGy) were performed. The woman had no headache complains nor showed any focal neurologic deficit during the six months follow-up period. We report a case of monostotic eosinophilic granuloma of the skull with review of the pertinent literatures.

From January, 1992 to June, 1996, )7 patients with flail chest were treated at Sonnchunhyang university hospital. 15 patients were managed by internal fixation of fractured ribs, whereas the remaining 22 patients were managed by endotracheal intubation and intermittent positive-pressure ventilation alone. There were no difference between two groups in age, sex, the severity of injury to the chest wall and the nature of associated injuries. Average dur'Btion of assisted ventilation was 5.7 +/-1.7 days in the patients treated by internal fixation versus 8.7 +/-3.3 days In the patients treated by continuous me hanical ventilation. Average stay in the intensive care unit was 8.3 +/-3.9 days for the patients treated by internal fixation, whereas it was 13.2+/-4.1 days in the group treated by continuous mechanical ventilation alone. In the group treated by internal fixation, complications were 3 atelectases(20.0%), 1 pneumonia(6.7%), 2 operative wound problems(12.3%) and 1 barotrauma(6.7%). In the other group, 7 atelectases(31.8%), 4 pneumonitis(18.2%), 2 empyemas(9.1%) and 3 barotraumas(1).6%). The mortality rate was 13.3%(2/15) in the surgically treated patients, whereas it was 22.7%(5122) in the other group. The treatment of flail chest by internal fixation resulted in speedy recovery, decreased complications and mortalities, and better ultimatc cosmetic and functional results.

PURPOSE: In the case of serious respiratory distress syndrome (RDS) or relapse of clinical appearances after single treatment, we obtained more effective results with multiple-dose surfactant replacement therapy. We carried out this investigation for comparing and observing clinical progress between single-dose (group S) and multiple-dose (group M) pulmonary surfactant treatment group of neonatal RDS. METHODS: We investigated 48 neonates who were diagnosed as RDS and treated with pulmonary surfactant (PS) replacement therapy in NICU of Kyunghee University hospital from January 2002 to March 2004, then we compared and verified clinical progress of 32 neonates in group S with that of 16 neonates in group M. RESULTS: There were no significant statistical differences in average birth weights, average gestational periods, initial pH values of birth, whether operation of resuscitation at that time of birth was made or not, whether prenatal steroid prescription for mother, RDS classification standardized by Bomsel, and ventilation index (VI) before instillation of PS of two groups. However, there was significant statistical difference in a/A PO2 (P< 0.05). We could observe changes of VI and a/A PO2 within 72 hours have been continuously improved at group S rather than group M. In spite of relapses, group M changed for the better after second dose. There were also no significant differences between the two groups in duration of ventilator therapy, mortality within 28 days after birth, intraventricular hemorrhage by complication, retinopathy of premature, necrotizing enterocolitis, chronic lung diseases, sepsis, and DIC. CONCLUSION: In these relapse cases, as there were no significant differences in the mortality rate and the occurence of complication between group S and group M, the requirement of multiple-dose PS replacement therapy which brought improvement of prognosis was emphasized.
