Left ventricular hypertrophy in patients with aortic valve disease has long been recognized as a significant risk factor for aortic valve replacement. Higher operative mortality in such patients has been attributed to poor myocardial preservation. In these patients improvement of left ventricular subendocardial blood flow during reperfusion seems to be mandatory to avoid subendocardial injury. Therefore, we attempted to increase subendocardial blood flow during reperfusion by terminal warm blood cardioplegia (TWBCP) followed by controlled aortic root reperfusion (CARR) in patients requiring isolated aortic valve replacement. The patients with TWBCP and CARR had a tendency towards severe left ventricular hypertrophy and more advanced NYHA function class compared to those with hypothermic cardioplegia alone. Nevertheless, the patients with TWBCP and CARR showed significantly better recovery of left ventricular function, i.e., spontaneous recovery of beating and higher cardiac index as well as left ventricular stroke work index, despite significantly less catecholamine support. These resuls suggest that TWBCP followed by CARR may offer significant benefits over unmodified reperfusion during aortic valve replacement for patients with severe left ventricular hypertrophy.

A 50-year-old man was diagnosed as having aortic valve insufficiency, complete occlusion of the right coronary artery and 75% stenosis of the left main trunk due to syphilitic aortitis. Aortic valve replacement and coronary artery bypass grafting to three vessels were successfully performed. The selection of surgical procedures for the coronary lesion with syphilitic aortitis should be made carefully, since the progression of aortic root inflammation in the acute phase and the development of atherosclerotic changes are not preventable in the future. It is most important to select effective and safe surgical interventions, especially for patients with such a low cardiac function as our patient.

In a consecutive series of abdominal aortic aneurysm repairs, a non-washing autotransfusion unit system was used in 47 patients, and was not used in 25. In the 47 patients treated with the autotransfusion unit, the average amount of autotransfused blood was 1, 109±131ml in elective cases. The amount of banked blood transfusion was significantly smaller in autotransfused patients (mean; 712ml), compared to non-autotransfused patients (mean; 1, 405ml). Postoperative levels of serum bilirubin were higher in patients with greater autotransfused blood volumes than those with smaller volumes. The combination of preoperative autologous blood donation (2-3 units) and intraoperative autotransfusion is necessary to perform abdominal aortic aneurysm repair without homologous blood transfusion.

Neuroendocrine small cell carcinoma is very rare in comparison with carcinoma of the cervix. In addition, it causes quite often metastasizes and has high recurrence rates. Furthermore, the mortality rate is high even among patients with early stage disease treated with common chemotherapy. We described a recurrent case of neuroendocrine small cell carcinoma, in which radiation therapy was delivered successfully but the disease relapsed during postoperative chemotherapy.

Saffron (Crocus sativus L.) is classified as a beneficial herb in the treatment of “Oketsu,” eliminating blood stagnation. The clinical symptoms of “Oketsu” include feeling cold and arthralgia. The pathological condition of “Oketsu” is considered to be increased blood viscosity and microvascular disorders.However, no useful biomarker has been reported for evaluation of the degree of “Oketsu.” Here, we investigated the clinical effect of saffron on the symptoms of “Oketsu” in patients with autoimmune diseases. At the same time, we measured the plasma levels of platelet factor 4 (PF-4) and beta-thromboglobulin (β-TG) as platelet activation markers. Seventy-one patients (66 women and 5 men, mean age 52.3 ± 16.1) were studied. They were administered saffron (300mg∼900mg) with traditional Kampo medicine. The clinical symptoms of “Oketsu” improved (80.9%, n=38/47) and we measured PF-4 and β-TG in pre-and post-saffron treatment periods. The plasma levels of PF-4 and β-TG significantly decreased after saffron therapy (PF-4 : before 49.6 ± 29.8, after 24.0 ± 19.6ng/ml, β-TG : before 117.5 ± 64.0, after 64.6 ± 47.1ng/ml;paired t-test, p < 0.0001, respectively). These results suggest that saffron is effective in treatment of the symptoms of “Oketsu” in allergy and collagen disease patients. Moreover, PF-4 and β-TG may be useful biomarkers of the degree of “Oketsu.”
