Patient 1 was a 62-year-old woman who had been treated for hypertension for three years. Stanford A type acute aortic dissection occurred accompanied by right coronary ischemia. CABG and graft replacement of the ascending aorta were performed 8 hours after the onset of coronary ischemia, but after cardiopulmonary bypass the patient could not be weaned from the RVAD because of right ventricular infarction. On the 8th day after operation, she died due to right heart failure. Patient 2 was a 72-year-old male. Stanford A acute aortic dissection occurred and right coronary ischemia appeared during UCG examination in the ICU. CABG and graft replacement of the ascending aorta and the aortic arch were carried out less than 1 hour from the onset of coronary ischemia. The postoperative course was satisfactory and uncomplicated. If the dissection extends to the aortic root, it is important to monitor the ECG carefully to detect myocardial ischemic changes. In cases with coronary ischemia, early operation and CABG are mandatory.

OBJECTIVE: The aim of the present study was to perform a subgroup analysis of data from a phase II global, multi-center, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of bitopertin, a glycine reuptake inhibitor that activates N-methyl-D-aspartate receptors by increasing the concentration of glycine in the synaptic cleft, in Japanese and non-Japanese patients with schizophrenia and predominant negative symptoms. METHODS: Patients with schizophrenia and predominant negative symptoms on one or two antipsychotic drugs, including atypical antipsychotic drugs (olanzapine, risperidone, quetiapine, aripiprazole, and paliperidone) as the primary treatment, received bitopertin (10, 30, or 60 mg/day) or placebo once daily for 8 weeks as an add-on treatment. Efficacy was assessed using the Positive and Negative Syndrome Scale (PANSS) negative symptom factor score (NSFS). RESULTS: The efficacy of bitopertin (10 mg and 30 mg) was similar between Japanese and non-Japanese patients. In the bitopertin 60-mg group, no difference from the placebo group was observed in Japanese or non-Japanese patients. The response to placebo was lower in Japanese patients, and there was a trend towards a greater difference in the change in PANSS NSFS between the placebo group and the 10-mg and 30-mg groups among Japanese patients. The safety profile of bitopertin was favorable in Japanese and non-Japanese patients. CONCLUSION: According to this subgroup analysis from a global phase II study of bitopertin, there was no difference in terms of efficacy and safety between Japanese and non-Japanese patients.
