Objectives : Mediastinitis results in significant morbidity in pediatric patients after cardiac surgery. The management of mediastinitis is not well established in the pediatric population. Our strategy for pediatric mediastinitis after cardiac surgery consists of rapid introduction of simple vacuum-assisted drainage system and sternal closure without plombage under aseptic conditions. The efficacy of our strategy was examined. Methods : The records of 7 pediatric patients with mediastinitis after cardiac surgery managed with this drainage system from May 2006 to May 2013 were retrospectively reviewed. The median age of the patients was 20.5 months and median body weight was 9.7 kg. Mediastinitis occurred 1-3 weeks after surgery. The mediastinum was re-explored immediately under general anesthesia after the diagnosis was made, and continuous drainage was used after extensive debridement was performed. We developed a simple vacuum-assisted drainage system consisting of conventional polyurethane foam, surgical drape containing povidone-iodine, and 1 to 3 silicone drainage tubes connected to a drain aspirator (-99 cmH₂O). Patients were allowed oral intake and resumption of daily activity after extubation. The components of the drainage system were exchanged every 2-3 days. The sternum was closed without the use of the omentum or muscle for plombage of the mediastinum after two negative topical swab cultures were obtained. Results : Negative topical swab cultures were obtained in all cases (3-12 days after the drainage commencement) and the sternum was closed 7-19 days after the drainage commencement. The median duration of hospital stay was 31 days (range, 14-47). Although one patient with prenatal infection died of aortic rupture, the remaining six children survived and did not experience recurrence after hospital discharge. Conclusion : The simple vacuum-assisted drainage system enabled rapid control of wound bacterial infection and sternal closure in postoperative pediatric mediastinitis without the need for special, and expensive devices.

We report a case of successful operation for multiple giant aneurysms with a right coronary artery fistula from the right coronary artery to the left atrium. A 35-years-old woman was found to have a right coronary artery aneurysm with a maximum diameter of 85mm, and two other coronary artery aneurysms with maximum diameters of 40 mm along the coronary fistula, which arose from the proximal right coronary artery, traversed the root of the left atrium, and drained into the left atrium. Surgical treatment was indicated to relieve symptoms and to prevent possible rupture of the aneurysms. She underwent resection of coronary artery aneurysms, closure of orifices of the fistula and coronary bypass grafting to the right coronary artery with cardiopulmonary bypass. Her postoperative course was uneventful, and she was discharged in good condition.

OBJECTIVE: Interest in the "at-risk mental state" (ARMS) for psychosis has increased because early intervention is expected to delay or prevent the onset of schizophrenia. However, the optimum intervention strategy remains controversial, especially with regard to antipsychotics. Although administration of antipsychotic medications is often associated with adverse effects and raises ethical considerations, recent studies have shown that some novel antipsychotics are safer and more tolerable for young people than conventional antipsychotics. We investigated whether administration of perospirone, a combined serotonin (5-HT)/dopamine antagonist and 5-HT1A receptor agonist, could alleviate prodromal symptoms and be well tolerated by clinical high risk patients. METHODS: The participants were outpatients seeking help. The Structured Interview for Prodromal Symptoms was performed in patients identified as being at clinical high risk. The Scale of Prodromal Symptoms (SOPS) was also completed and changes of subjective experience were assessed with the Subjective Well-being under Neuroleptics, short version. The incidence of akathisia was recorded by using the Barnes Akathisia Scale. Subjects were monitored for 26 weeks after starting medication. RESULTS: SOPS scores improved significantly after 26 weeks of perospirone therapy, while BAS scores did not show deterioration. No serious adverse events occurred during the study. CONCLUSION: This trial suggests that perospirone therapy provides a clinical benefit for clinical high risk subjects without causing serious adverse events. Although further placebo-controlled studies are needed for confirmation, perospirone might be one of optimum treatments for individuals at imminent risk of psychosis.

The system of the Japanese Board of Cardiovascular Surgery is changing. Since the last time, we have deliberated on the medical specialty board for U-40 column articles about the problems faced by young cardiovascular surgeons. This time, we conducted the second survey to U-40 members about the realities of becoming a board-certified cardiovascular surgeon. The results showed the circumstances and details on how to acquire the board certification. Moreover, we discussed about the current problems and future perspectives for the young cardiovascular surgeons.
