A 72-year-old man who suddenly felt an excessive thirst and developed pollakisuria and high fever on Sept. 29, 2001. A general practitioner initially diagnosed him as having urinary tract infection on the same day. Vomiting and unconscionsnes occurred on Oct. 3. He was brought to our hospital by ambulance. Laboratory data on admission showed plasma glucose of 1110 mg/dl, blood pH of 7.167 and HCO3- of 7.6mmol/L, and positive urinary ketone bodies, compatible with diabetic ketoacidosis. Serum amylase was elevated, but he had no symptoms of acute pancreatitis. Insulin therapy was started immediately and hyperglyvemia was improved. He has never had diabetes mellitus and his HbA1c was normal (5.3%). His urinary C-peptide was very low (2.4 μg/day) and diabetes-related autoantibodies including anti-GAD, IA-2 antibodies and ICA were negative. So his case was diagnosed as fulminant type 1 diabetes mellitus. Fulminant type 1 diabetes, which has been brought to light by Dr Imagawa’s group, is characterized by near-nomal HbA1c despite diabetic ketoacidosis, rapid loss of insulin secretion and absence of diabetes-related autoantibodies.Great care is needed to recognize the patients with fulminant type 1 diabetes among the elderly with symptoms of urinary tract infection. Here, we reported the case of an aged man who developed aypical fulminant type 1 diabetes.

Between 1970 and October, 1992, 120 cases of abdominal aortic aneurysms (AAA) were treated for surgical repair. Thirteen of these cases (11%) were performed with simultaneous repair for coexistent visceral vascular diseases and other intestinal organ diseases. Another 9 patients (7.5%) were treated with coronary revascularization for combined ischemic heart disease. Six of these cases received both operations during the same hospital stay. Our surgical strategy for coexistent AAA and ischemic coronary artery disease is basically a staged operation. Coronary revascularization should precede AAA repair. Operative mortality was 1.1 percent for elective AAA repair. Long-term survival was 78% for elective surgery with a mean follow-up of 51 months, and 52% for emergency surgery with a mean follow-up of 46 months. Major risks for late death were malignant neoplasms and ischemic coronary artery disease. Survival rate of the 9 patients with successful concomitant coronary revascularization and AAA repair was 89% after 51 months of mean follow-up. We conclude that re-evaluation for coexistent ischemic heart disease is the most important point for management before and after AAA repair.

Among the 203 cases of aortic valvular surgery, we experienced 8 cases of acute coronary insufficiency during the early postsurgical period. Five cases suffered from right coronary insufficiency. The other 2 cases had left coronary failure, and the remaining case had both. The main symptom of right coronary failure was right ventricular dysfunction, resulting in inability to wean from cardiopulmonary bypass in 3 cases, and left ventricular dysfunction due to inferior myocardial infarction in 2 cases. On the other hand, the main symptom of left coronary insufficiency was acute left ventricular pump failure with a broad anteroseptal infarction, and cardiac arrest occurred in the other 2. All patients receiving an emergency coronary artery bypass graft survived. Two cases expired due to thromboembolism in the interposed graft to the left coronary ostium in Cabrol's or Piehler's procedures. In the 6 survivors we could not detect any recent coronary lesions by postsurgical coronary cineangiography. We suggest that the pathophysiology of this phenomenon was coronary artery spasm and a lack of coronary reserve capacity in severe left ventricular hypertrophy of aortic valvular disease combined with diastolic dysfunction. Prompt coronary artery bypass grafting and a careful myocardial protection using retrograde cardioplegic solutions might save patients in this critical condition and an appropriate decision on the surgical indications for aortic valvular surgery is necessary before the occurrence of left ventricular diastolic dysfunction and demand ischemia.

We report a successful staged repair of anomalous origin of right pulmonary artery from the ascending aorta in a neonate. A two-day-old girl, who suffered from severe circulatory failure, was admitted. In spite of all medical treatment, acidosis and systemic hypotension developed. Right pulmonary artery banding was performed in an emergency procedure, resulting in immediate elevation of systemic blood pressure. Definitive operation was subsequently performed on the 48th day after birth. The right pulmonary artery, which was de-banded and divided from aorta, was anastomosed directly to the pulmonary trunk in a side-to-end manner. The postoperative course was uneventful and the pulmonary artery pressure was within the normal range.
