BACKGROUND: Balloon PTCA for the distal, long, eccentric coronary artery stenosis will be at high risk for severe dissection or acute occlusion during or after procedure. METHODS AND RESULTS: High Speed Rotational Atherectomy followd by low pressure balloon angioplasty due to distal, long, eccentric coronary artery stenosis. Rotational coronary atherectomy debulked the lesion quickly without difficulty. Rotational Coronary Atherectomy with adjuctive low pressure balloon inflation was successful without event. CONCLUSIONS: This case illustrates the point that complementary deployment of devices may not only improve success of percutaneous coronary intervention, but also may extend its scope.

The prognostic factors for extrahepatic biliary atresia (EHBA) after Kasai portoenterostomy include the patient's age at portoenterostomy (age), size of bile duct in theporta hepatis (size), clearance of jaundice after operation (clearance) and the surgeon's experience. The aim of this study is to examine the most significant prognostic factor of EHBA after Kasai portoenterostomy. This retrospective study was done in 51 cases of EHBA that received Kasai portoenterostomy by one pediatric surgeon. For the statistical analysis, Kaplan-Meier method, Logrank test and Cox regression test were used. A p value of less than 0.05 was considered to be significant. Fifteen patients were regarded as dead in this study, including nine cases of liver transplantation. There was no significant difference of survival to age. The age is also not a significant risk factor for survival in this study (Cox Regression test; p = 0.63). There was no significant difference in survival in relation to the size of bile duct. However, bile duct size was a significant risk factor for survival (Cox Regression test; p = 0.002). There was a significant difference in relation to survival and clearance (Kaplan-Meier method; p = 0.02). The clearing was also a significant risk factor for survival (Cox Regression test; p = 0.001). The clearance of jaundice is the most significant prognostic factor of EHBA after Kasai portoenterostomy.

Although the management of fractures of the calcaneus still remains controversial, open reduction and internal fixation is gaining in popularity as the method of choice for the treatment of displaced intraarticular calcaneal fractures. However, open methods can make several complications such as neurovascular injury and infection. Thus we have performed the new technique of arthroscopic reduction and minimal internal fixation for displaced intraarticular calcaneal fractures in 5 cases. The results were evaluated between 12 and 16 months after surgery. A Bohler angle was restored to 25degrees-40degrees in all cases. Anatomical reduction of articular surface were obtained from 4 cases out of 5. No complications were found except 1 peroneal tendinitis. The clinical results by Creighton-Nebraska health foundation assessment for fractures of the calcaneus were 3 excellent, 1 good and 1 fair. Even though this was a few case and a short term follow-up study, the arthroscopic assisted management of displaced intraarticular calcaneal fracture induced a little complications and satisfactory results.

To evaluate the sensitivity and specificity of transthoracic fine needle aspiration cytology(TFNAC) in the preoperative diagnosis of pulmonary nodules, a retrospective analysis was carried out on a consecutive series of 200 TFNACs. They included 186 primary malignant tumors, 66 squamous cell carcinomas, 65 adenocarcinomas, 36 small cell carcinomas, 7 large cell carcinomas, 4 carcinoids, 8 others, 9 metastatic tumors, and 5 benign tumors. On cytohistologic correlation of malignant pulmonary tumors, the pro- cedure had a sensitivity of 97.3% and a specificity of 100%. A 86.6% correct correlation between the cytologic and histologic diagnoses was achieved. Five out of the 7 undifferentiated large cell carcinomas, 10 out of the 65 adenocarcinomas, 2 out of the 36 small cell carcinomas, and 2 out of the 66 squamous cell carcinomas were turned out to be mistyped in cytologic diagnosis. We concluded that TFNAC is a highly sensitive and specific preoperative diagnostic procedure in the investigation of patients with discrete pulmonary nodules in whom the specific cell type of the malignant neoplasm has important implications in treatment modality and prognosis.

BACKGROUND: There are several ways to treat for recurrent pericardial effussion and cardiac tamponade due to malignancy. They are repeated pericardiocentesis, pericardial instillation of sclerosing and chemotherapeutic agents, surgical creation of a pericardial window and transthoracic pericardiectomy. Surgical techniques are usually effective but bear a significant morbidity and mortality especially in chronic debilitating cancer patients. So percutaneous balloon pericardial window as an alternative to surgery in these patients. METHODS: After pericardiocentesis was performed, a 0.035 inch J-tip guidewire was advanced into the pericardial space. And a pigtail catheter was advanced over the wire. A moderate amount of pericardial fluid were removed. A nd then the pigtail catheter was withdrawn and 8F sheath was inserted. A20mm diameter, 4cm long(Single balloon method) or two 10mm diameter, 4cm long balloon dilating catheter(Double balloon medium) was advanced over the wire to straddle the parietal pericardial border though the sheath. Several inflations of the balloon with a solution containing 50% radiographic contrast medium were performed until disappearance of the balloon waist. After balloon dilation, contrast medium from the pericardial space to subcutaneous tisse suggesting successful PBPWF. Single ballon method was employed in 4 patients and Dould balloon method in 2 patients. RESULT: We performed percutaneous balloon pericardial window formation in 6 patiemts with malignant pericardial effusion. We did percutaneous balloon pericardial window formation successfully in 5 patients and failed due to adhesion of parietal pericardium in 1 patient. One patient developed recurrent pericardial effusion with tamponade at a mean follow-up of 11.49.6 months(1.5-26 months). Conclusion: These results suggest that PBPWF is an alternative method less invasive than subxiphoid surgical windowing, espesially in critically ill patients with recurrent malignant pericardial effussion. It carries less risks and has more constant effect than repeated pericardiocentesis.

It has been widely accepted that complete surgical resection of hepatoblastoma is essential for long-term survival. But unfortunately less that 50% of hepatic tumors in children can be totally removed at the time of diagnosis. This report is to present the experience of successful resection of hepatoblastoma after concurrent radiotherapy with transarterial chemoinfusion in a child. We believe this modality of treatment enables complete resection of unresectable hepatoblastoma, which is resistant to the systemic chemotherapy.

We report a cace of 69-year-old man who developed massive pulmonary hemorrhage and subsuquent adult respiratory distress syndrome following intravenous urokinase for acute myocardial infarction. Pulmonary hemorrhage is a rare but a potentially life-threatening complication after thrombolytic therapy and should be considered in the differential diagnosis of pulmonary infiltrates of falling hemoglobin after thrombolytic therapy for acute myocardial infarction with no obvious site of bleeding.

A collodion baby is born with a tough, inelastic parchment-like membrane covering the whole body surface. As the meinbrane fissures and peels, a more characteristic ichthyosiform change is evident beneath the collodion membrane. Uncommonly, normal skin is found under it. We herein present two cases af collodion baby, which were confirmed as a sporadic case of lamellar ichthyosis and a case of lamellar exfoliation of the newborn, respectively, after long-term clinical observation. It is necessary that detailed genetical and molecular biological studies should be perforrned in order to elucidate the fur:damental, molecular changes that cause these dramatic cutaneous changes.
