A pilot study of the Doppler renal arterial flow pattern was done on 34 patients (68 kidneys) with benign prostatic hypertrophy, 14 patients (28 kidneys) with hydronephrosis and 22 patients (37 kidneys) with reflux nephropathy. Renal scintigraphy was also performed besides the color Doppler scanning.
Results:
Mean minimum blood flow values were significantly smaller in all the subjects than those in normal control groups with one of the three diseases respectively
In patients with reflux nephropathy, minimum blood flow values were extremely low, suggesting the severe scars and scarce blood flow. A high correlation was found between uptake rates measured by renal scintigram and minimum blood flow. This fact suggests that the blood flow scan can reveal the profile of the renal function.
We conclude that the color Doppler sonography is useful in a routine initial examination and a simple follow-up test for detecting renal dysfunction in some urological diseases.

Medical professionalism, which is of great interest in most countries, underpins the relationship between patients and doctors. The concepts of medical professionalism should be understandable not only by physicians but also by patients. However, there are few studies that evaluate the concept of medical professionalism from patients' perspective.a) We conducted two focus group interviews with 12 people who were not health care professionals. One interview was done with people who were living in Tokyo and one with people living in Osaka. Each interview was one hour long. During the interviews, we explored themes related to medical professionalism from patients' perspectives.b) We qualitatively analyzed response data from audio records of the interview and inductively extracted categories pertaining to medical professionalism. We compared our findings with the domains of the American Board of Internal Medicine's Charter on Professionalism (CP).c) We found 5 themes; 1) Primacy of patient welfare 2) Fairness 3) Social responsibility 4) Maintaining appropriate relations with industry 5) Maintaining appropriate relations with patients.d) Although our themes are almost equivalent to the principles cited in CP, there are some differences, such as the importance of maintaining appropriate relations with patients.e) Given the current findings, medical educators and trainers should continue to develop the Japanese concepts of medical professionalism in a manner that takes into consideration patients' perspectives.

ABSTRACT : Both primary biliary cirrhosis (PBC) and autoimmune hemolytic anemia (AIHA) are uncommon diseases. Immunological dysregulation is suggested as a causative factor for both diseases. We report a 77-year-old woman who suffered from warm type AIHA complicated by PBC. Her direct antiglobulin test was positive for IgG, and negative for C3. Both anti-mitochondrial antibody and its M2 component were detected. Both alkaline phosphatase (Alp) and IgM were elevated in the serum. She was initially treated with steroids for 8 months. Her steroids were discontinued when she underwent a laparoscopic splenectomy. Ursodeoxycholic acid was discontinued due to an allergic skin reaction. Her Alp improved with bezafibrate.

We present a rare case of a 59-year-old-man with a diagnosis of hypertrophic cardiomyopathy (HCM) complicated with left ventricular thrombus. He was admitted to our hospital because of acute re-occlusion of the right brachial artery. Thrombectomy was performed and reperfusion was obtained. Anti-coagulation therapy was started from that day. Four days after surgery, echocardiography revealed mobile thrombus in left ventricular apical aneurysm that was not detected on admission. An emergency thrombectomy and left ventriculoplasty was performed. The patient was discharged 22 days after surgery in good condition.

We report 2 cases of successful proximal reoperations after acute type A dissection. Case 1 : A 53-year-old man underwent ascending aorta and aortic arch replacement and aortic valve re-suspension for acute type A dissection with aortic valve regurgitation in 1992. Thirteen years after the first operation, computed tomography demonstrated a Valsalva aneurysm (74 mm) and Doppler echocardiography showed moderate aortic valve regurgitation. Therefore, we performed an operation. We could not locate the dissection in the Valsalva sinus, and the aortic valve cusps had organic change. A David procedure was performed. The postoperative course was uneventful and he was discharged on the 19th postoperative day. Case 2 : A 65-year-old woman underwent ascending aorta replacement and aortic valve resuspension for acute type A dissection with aortic valve regurgitation in 1997, but 11 years after the first operation, computed tomography demonstrated a Valsalva aneurysm (55 mm) and arch aneurysm (65 mm) with stenosis of the innominate vein and she had facial and left arm edema. Doppler echocardiography showed moderate aortic valve regurgitation. We could not find the location of dissection in the Valsalva sinus or aortic arch, and aortic valve cusps had no organic change. A Bentall procedure and total arch replacement were performed and her postoperative course was uneventful.

We report a case of a 64-year-old man who had a fistula from the right coronary artery to the right ventricle, with an asymptomatic giant coronary aneurysm. Multi-detector computer tomography showed an aneurysm from the sinus of Valsalva to the mid-right coronary artery (RCA). Its diameter was over 50 mm. We performed aneurysmectomy direct closure of the fistula, and coronary artery bypass graft with saphenous vein graft cardiopulmonary bypass. The enlarged RCA orifice was closed with a vascular prosthesis, and the postoperative course was uneventful.

We investigated the outcomes of nephron-sparing surgery in patients with small renal cell carcinomas by retrospectively reviewing the records of 20 elective cases of nephron-sparing surgery performed from 1994 to 2003. All patients had low pathologic stage, localized, unilateral tumors smaller than 4 cm and sporadic renal cell carcinomas. There were no significant differences between mean preoperative serum creatinine levels and postoperative levels. Nephron-sparing surgery may be safe and curative treatment for low pathologic stage, localized, unilateral tumors smaller than 4 cm and sporadic renal cell carcinomas.
