OBJECTIVE:To evaluate the biodurability of the covering material in retrievable metallic stents covered with polycarbonate polyurethane. MATERIALS AND METHODS: Using a peristaltic pump at a constant rate of 1ml/min, bile was recirculated from a reservoir through a long tube containing four stents. Each of these was removed from the system every two weeks and a radial tensile strength test and scanning electron microscopy (SEM) were performed. Each stent, removed at 2, 4, 6 and 8 weeks, was compared with a control stent not exposed to bile juice. RESULTS: Gross examination showed that stents were intact at 2 weeks, but at 4, 6 and 8 weeks cracks were observed. The size of these increased gradually in accordance with the duration of exposure, and at 8 weeks several large holes in the polyurethane membrane were evident. With regard to radial tensile strength, extension and peak load at break were 84.47% and 10.030 N/mm, 54.90% and 6.769 N/mm, 16.55% and 2.452 N/mm, 11.21% and 1.373 N/mm at 0, 2, 4 and 6 weeks, respectively. Scanning electron microscopy at 2 weeks revealed intermittent pitting and cracking, and examination at 4, 6 and 8 weeks showed that the size of these defects was gradually increasing. CONCLUSION: When the polyurethane membrane was exposed to bile, biodegradation was first observed at week two and increased gradually according to the duration of exposure.

A rare case of ventriculitis associated with the obstruction of aqueduct of Sylvius is reported and the pertinent literature reviewed. A 24 years old male, who had been suffering from a longstanding chronic pyogenic ear disease since childhood, was admitted to our clinic in Dec. 1973 with a comatose state. Contrast radiology showed the obstructive hydrocephalus with the occluded aqueduct of Sylvius, but neither intracerebral or intracerebellar space consuming mass presented. Cerebrospinal and ventricular fluid revealed a marked growth of Escherichia Coli. So ventriculitis complicating obstruction of the aqueduct of Sylvius due to chronic suppurative otitis media and mastoiditis was diagnosed in this patient, and treated by Torkildsen's operation with proper chemotherapy and resulted in good recovery. We experienced that ventriculitis initiated from meningitis might give rise to obstruction of the aqueduct of Sylvius and it could be considered as a brain abscess superimposed raised intracranial pressure from obstructive hydrocephalus.

Rhabdomyosarcoma originating from the chest wall is a rare malignant tumor in children and was considered to be guarded in prognosis previously. However, recent advances in multidisciplinary treatment of rhabdomyosarcoma in children have improved the disease free survival rate. Authors report a case of alveolar rhabdomyosarcoma, stage III, originating from the chest wall who is surviving free of disease for 15 months with aggressive chemotherapy and radiotherapy.

Severe acute respiratory distress syndrome (ARDS) is a life-threatening disease with a high mortality rate. Although many therapeutic trials have been performed for improving the mortality of severe ARDS, limited strategies have demonstrated better outcomes. Recently, advanced rescue therapies such as extracorporeal membrane oxygenation (ECMO) made it possible to consider lung transplantation (LTPL) in patients with ARDS, but data is insufficient. We report a 62-year-old man who underwent LTPL due to ARDS with no underlying lung disease. He was admitted to the hospital due to influenza A pneumonia-induced ARDS. Although he was supported by ECMO, he progressively deteriorated. We judged that his lungs were irreversibly damaged and decided he needed to undergo LTPL. Finally, bilateral sequential double-lung transplantation was successfully performed. He has since been alive for three years. Conclusively, we demonstrate that LTPL can be a therapeutic option in patients with severe ARDS refractory to conventional therapies.
