Prediction of remission in Graves' disease after thionamide therapy by technetium-99m early uptake]

In the clinical management of Graves' thyrotoxicosis, one of the most important subject is when to stop antithyroid drugs after achieving an euthyroid state. T3 suppression test and other methods have been used to forecast the outcome after drug cessation, but the results were not always satisfactory. We have attempted to predict remission of Graves' disease by single measurement of early technetium uptake without administration of triiodothyronine. Drugs were discontinued in the seventy-five patients with Graves' disease on maintenance doses of either methimazole or propylthiouracil who showed normalized uptake (4.0% or less). Of 64 patients evaluable after twelve months, 55 (86%) remained euthyroid, 8 relapsed, and 1 became hypothyroid. With its accuracy in prediction of short-term remission comparable or superior to T3 suppression test, this rapid and simple method seemed suitable for routine use in clinical practice.     

Successful treatment with balloon dilatation using a double‐balloon enteroscope for a stricture in the small bowel of a patient with Crohn's disease

The requirement for endoscopic access to a stricture is a major limitation of the endoscopic dilatation for the treatment of strictures in the gastrointestinal tract. We have developed the double‐balloon enteroscopy method that enables visualization of the entire small bowel. In addition, double‐balloon enteroscopy has a potential for the interventional therapy including dilatation of strictures. We present here a case of jejunal strictures in a 47‐year‐old woman with Crohn's disease successfully treated with a balloon catheter in combination with double‐balloon enteroscopy. Balloon dilation with double‐balloon enteroscopy is a promising method for the treatment of small bowel strictures in Crohn's disease.     

Crohn's ileocolitis with initially superimposed cytomegalovirus infection, resembling intestinal tuberculosis]

We describe a case of 41-year-old Japanese man with Crohn's ileocolitis and cytomegalovirus infection, confirmed by histology of ileal ulcers. Although his colonoscopic and radiological features resembled those of intestinal tuberculosis, granulomas of typical Crohn's disease were evident on histology of biopsy specimens taken from the duodenum and colon. The lesions remain unchanged even after 1.5 years by oral administration of salazosulphapyridine 3g daily.     

Carcinoma of the main hepatic duct junction: indications, operative morbidity and mortality, and long-term survival

Carcinoma of the main hepatic duct junction tends to spread extensively along the hepatic ducts into the liver parenchyma. Therefore extensive resection of the bile ducts combined with hepatic resection is the procedure of choice. Between January 1973 and April 1989, 25 of 50 patients with this type of carcinoma underwent resection, a resectability rate of 50%. One patient died of staphylococcal sepsis on the postoperative day 42 after right trisegmentectomy and resection of the bile ducts, a hospital death rate of 4%. Twenty-four patients were discharged from the hospital. The 5-year actuarial survival rate calculated by the Kaplan-Meier method was 19%. Four patients lived longer than 5 years after surgery; the longest survival was 9 years after right trisegmentectomy and resection of the bile ducts. These four patients had clear margins at the resected bile ducts. This article was designed to clarify the point at issue by presenting our results in terms of indications, operative morbidity and mortality, and long-term survival.     

A successful surgical case of aortic arch aneurysm associated with aortic regurgitation

A 57-year-old male patient with aortic regurgitation and aneurysm of the ascending aorta and the aortic arch underwent aortic valve replacement and graft replacement from the ascending aorta to the aortic arch. The operation was done using cardio-pulmonary bypass and selective cerebral perfusion with deep hypothermia. Postoperative DSA revealed no dilatation of the sinus Valsalva and a good configuration of the anastomosis. It seems that selective cerebral perfusion with deep hypothermia is a safe method to prevent cerebral damage in a case of arch aneurysm.     

Metabolic syndrome, C-reactive protein and increased arterial stiffness in Japanese subjects.

The aim of this study was to investigate whether the metabolic syndrome (MS) was associated with an elevated level of C-reactive protein (CRP) and increased arterial stiffness, and to clarify whether combined MS and CRP data had a stronger relation to arterial stiffness than did MS data alone. Brachial-ankle pulse wave velocity (baPWV), CRP, and conventional risk factors were evaluated in 3,412 men and 854 women. Adjusted mean values of baPWV in men with 0, 1, 2, and > or = 3 components were 1,309, 1,372, 1,422, and 1,462 cm/s, respectively (p for trend <0.001). Adjusted mean values of baPWV in women with 0, 1, 2, and > or =3 components were 1,212, 1,292, 1,357, and 1,391 cm/s, respectively (p for trend <0.001). Adjusted geometric mean concentrations of CRP in men with 0, 1, 2, and > or = 3 components were 0.036, 0.049, 0.059, and 0.076 mg/dI, respectively (p for trend <0.001). Adjusted geometric mean concentrations of CRP in women with 0, 1, 2, and > or = 3 components were 0.023, 0.030, 0.057, and 0.077 mg/dI, respectively (p for trend <0.001). In analyses of adjusted mean values of baPWV according to the number of MS components and according to CRP levels within or without top quartile levels, the p value for the trend was significant (<0.001) in both men and women but, in post hoc analyses, comparing high and low CRP levels in each MS component-number group, no significant difference was found. These results suggest that, for prediction of increased arterial stiffness, combining MS and CRP data has little additive effect compared to the use of MS data alone.
