Dissection of the sinus of Valsalva is an extremely rare accident during percutaneous coronary intervention (PCI), but it can lead to serious complications such as dissection of the ascending aorta. We experienced a localized dissection of the right coronary cusp without coronary artery involvement that was induced by a guiding catheter during PCI in a patient with acute myocardial infarction. The localized dissection showed pooling of the contrast medium in the acute phase, but it subsided spontaneously after 12 days without any sequelae. Manipulation of the guiding catheter should be performed with great caution not only in the coronary artery but also in the sinus of Valsalva. 相似文献

Tuberculosis (TB) treatment can cause serious sequelae including adverse effects such as anti-TB drug-induced hepatotoxicity (ATDH). We performed a candidate gene-based association study between single nucleotide polymorphisms (SNPs) in 10 genes in the antioxidant pathway and ATDH susceptibility. The subjects comprised 100 Japanese patients with pulmonary TB who received a treatment regimen including isoniazid and rifampicin. Out of them, 18 patients had ATDH. Thirty-four tag SNPs in 10 genes were analyzed by PCR-restriction fragment length polymorphism or PCR-direct DNA sequencing. The frequencies of alleles and genotypes between patients with and without ATDH were compared in three different genetic models. Statistical analyses revealed that a C/C genotype at rs11080344 in NOS2A, a C/C genotype at rs2070401 in BACH1, and a G/A or A/A genotype at rs4720833 in MAFK independently conferred ATDH susceptibility. Remarkably, the association of the latter two tag SNPs with ATDH susceptibility was highly statistically significant (P?=?0.0006) with an odds ratio of 9.730. This study is the first report to demonstrate that NOS2A, BACH1, and MAFK appear to be genetic determinants of ATDH in Japanese patients with TB. Furthermore, a combination of BACH1 and MAFK polymorphisms may be useful as new biomarkers to identify high-risk Japanese TB patients for ATDH. 相似文献

Purpose
The aim of this study was to investigate the outcomes correlated with our treatment strategy for prosthetic graft infection.Methods
Seventeen patients were treated for prosthetic graft infections between 1997 and 2009. Initially, total graft excision was applied in five cases, partial graft excision was applied in six cases and graft preservation with drainage and irrigation was applied in six cases. Among the graft-preserved cases, four patients were infected with methicillin-resistant Staphylococcus aureus (MRSA) and treated with gentian violet (GV).Results
The overall survival rate was 88 % at 30 days and 82 % at 1 year in this series. Of the excised cases, nine patients survived; however, two patients died. Among the cases in which MRSA-infected grafts were preserved, three patients survived; however, one patient died under a septicemic state. Infected graft preservation was applied at a high rate of 36 %, and the mortality rate remained at 16 %, without any signs of graft reinfection.Conclusions
In the treatment of infected grafts, the patient’s condition should be considered in order to select the appropriate treatment in each case. Graft preservation should be considered as an alternative treatment option, especially in high-risk patients, and GV can be effective for conservative treatment of prosthetic graft infections, including MRSA infections. 相似文献6.

Since the new organ transplantation law was established in 1997, 17 heart transplantations have been performed in Japan, 7 of which were carried out at Osaka University Hospital. Recipient diagnosis was dilated cardiomyopathy in 2, dilated phase of hypertrophic cardiomyopathy in 4, and post-myocarditis cardiomyopathy in 1. Ages ranged from 8 to 49 years with a mean of 35.3 years. Five patients were bridged with a left ventricular assist device. The waiting period was 182-977 days (mean, 643 days). There was no early or late death during follow-up of 1-4.8 years. Under a standard triple-drug regimen using mycophenolate, there were 3 rejection episodes greater than grade 3 in 2 patients, and humoral rejection requiring plasmapheresis in one. A young boy whose donor was a hemodynamically compromised adult developed neurological sequelae after resuscitation following ventricular tachycardia. All patients were discharged and went back to work or their regular daily life. Although the donor shortage is still severe in Japan, the resumption of heart transplantation has been satisfactory, and left ventricular assist devices have played a crucial role. 相似文献

Platelet activation and the formation of platelet microaggregates in coronary vessels play pivotal roles in myocardial ischemia and reperfusion injury. The Fc receptor gamma-chain (FcR gamma) is coexpressed with glycoprotein (GP) VI, forming a platelet collagen receptor, and the activation of platelets by collagen is closely coupled with tyrosine phosphorylation of the FcRgamma. To examine the functional significance of platelet FcR gamma/GPVI complex in the early phase of myocardial ischemia and reperfusion injury in mice, we performed coronary occlusion and reperfusion experiments using wild type mice and FcRgamma-deficient (FcRgamma(-/-)) mice that lack GPVI. The infarct size was significantly smaller in FcRgamma(-/-) mice subjected to occlusion and reperfusion of the coronary artery than in control FcR gamma(+/+) mice. Twenty-four hours after the reperfusion, electron microscopy of the injured tissue showed substantially more platelet aggregation and occlusive platelet microthrombi in the capillaries of the damaged areas of the wild type mice than in those of the FcR gamma(-/-) mice. Platelet Syk was scarcely activated in the FcR gamma(-/-) mice after myocardial ischemia and reperfusion, but significantly activated in the FcR gamma(+/+) mice. CD11b expression on neutrophils was elevated after myocardial ischemia and reperfusion in both mouse groups, whereas myeloperoxidase activity in the injured areas was significantly lower in the FcRgamma(-/-) mice than in the FcRgamma(+/+) mice. These results suggest that the collagen-induced activation of platelets through the FcR gamma plays a pivotal role in the extension of myocardial ischemia-reperfusion injury. FcRgamma and GPVI may be important therapeutic targets for myocardial ischemia-reperfusion injury. 相似文献

A 32-year-old woman with relapsed Philadelphia chromosome-positive acute lymphoblastic leukaemia was treated with imatinib mesylate (formerly STI571), a selective inhibitor of BCR/ABL tyrosine kinase. Although the initial marrow response was good and stably maintained, she subsequently relapsed with extensive infiltration of leukaemic cells into the central nervous system (CNS). After controlling her CNS disease with additional intrathecal chemotherapy, we measured the concentration of imatinib in cerebrospinal fluid (CSF) and blood simultaneously. The concentration of imatinib in CSF was about 92-fold lower than that in blood. These results suggest that imatinib poorly penetrates the blood-brain barrier and has limited activity against CNS leukaemia. 相似文献
