Background : Several studies have shown that Fontan circulation may lead to liver congestion and possible structural liver alteration. The aim of this study is to analyze the relationships between biochemical fibrosis markers and hemodynamic parameters in the long term after the Fontan operation.
Methods : The study enrolled 51 patients who underwent total cavopulmonary connection between March 1994 and July 2010. We analyzed the relationships between the 5 liver fibrosis markers (hyaluronic acid, retinol-binding protein, procollagen type III peptide, type IV collagen 7S, type IV collagen) and the 6 hemodynamic parameters (pulmonary artery pressure, pulmonary artery index, pulmonary vascular resistance, ejection fraction, atrioventricular valve regurgitation, cardiac index).
Results : Hyaluronic acid and type IV collagen 7S positively correlated with pulmonary artery pressure. Hyaluronic acid negatively correlated with ejection fraction, and type IV collagen 7S positively correlated with atrioventricular valve regurgitation in patients followed up for more than 8 years after Fontan completion. Pulmonary artery pressure was significantly higher in patients in whom type IV collagen 7S was elevated. Hyaluronic acid correlated with pulmonary vascular resistance (p=0.0035) and ejection fraction (p=0.014), as well as type IV collagen 7S with pulmonary artery pressure (p=0.0001) by multiple regression analysis.
Conclusion : Hyaluronic acid and type IV collagen 7S reflected the degree of hepatic congestion, and cardiac function, in the long term after the Fontan operation.

We report a case of syphilitic aortitis (SA) associated with severe right coronary ostial stenosis, aortic regurgitation (AR), and annuloaortic ectasia (AAE). A 48-year-old man presented to a regional hospital with easy fatigability and nocturnal dyspnea. Echocardiography revealed Seller's grade 3 AR. A computed tomography scan showed AAE, dilatation of the ascending aorta, and calcification of both coronary ostia. Coronary angiography demonstrated that the left coronary artery was intact ; however, the right coronary artery was obscure. Active syphilis was detected on routine blood tests on admission. Therefore, the patient was started on a course of ampicillin/sulbactam (ABPC/SBT). Subsequently, he underwent the Bentall procedure and coronary artery bypass grafting with the right internal thoracic artery. The intraoperative findings showed degeneration of the aorta and severe right coronary ostial stenosis. The pathological findings of the aortic wall and aortic valve were consistent with SA. The postoperative course was uneventful. The patient continued receiving ABPC/SBT for 3 weeks postoperatively, and was then switched to oral amoxicillin.

　　Since February, 2012, Anjo Kosei Hospital has embarked upon a new scheme for efficiently handling narcotics during surgical operations. For the purpose pharmacists are allowed to enter the operating room for a while. At the same time, the implementation of digital record keeping for narcotics management tasks has started, making it possible to simplify the handling of a great number of patients. By reviewing the effects on narcotics handling and hours billed, we could determine the effectiveness of operating room pharmacist-led narcotics management at Anjo Kosei. Out of narcotics prescriptions (n＝647) handled in the operating room for one month, 84.7% (548/647) was accounted for by prepared narcotics and 99.8% (646/647) by post-operation management. The introduction of the digital record system resulted in a reduction from 53.3±9.6 minutes to 39.6±6.3 minutes for narcotics preparation, and a reduction from 66.8±16.1 minutes to 41.1±13.5 minutes for post-operation management (p<0.01). It has added to the work efficiency and simplification of operations. Moreover, due to the intervention of pharmacists in the operating room, 92.3% of narcotics prescriptions was performed using the new management system within a relatively short time (80.8±18.4minutes). These data show that the introduction of the new scheme has resulted in more efficient management of narcotics at Anjo Kosei.
