A comparison of the epidemiology of youth-onset insulin-dependent diabetes mellitus between Japan and the United States (Allegheny County, Pennsylvania).

Children in the United States are almost 20 times more likely to develop insulin-dependent diabetes mellitus (IDDM) than children in Japan. Little is known about the differences between the two countries that might account for this very large difference in risk. The current research compared the characteristics of IDDM in Japan with those of the United States (Allegheny County, Pennsylvania). Seasonality, relationship to socioeconomic status, and age at onset were similar. There was some suggestion of a sex difference. Of interest was that reported recent infections at onset were much higher in the United States. In addition, the risk to first-degree relatives in Japan appeared to be somewhat lower than in the United States, although this may have been the result of differences in ascertainment. These results are discussed in relation to potential factors that might account for the major incidence differences.

The Pittsburgh Insulin-Dependent Diabetes Mellitus (IDDM) Morbidity and Mortality Study: case-control analyses of risk factors for mortality.

Although children with IDDM are at a sevenfold increased risk of dying when compared with nondiabetic individuals of the same age, the factors associated with the excess in mortality remain unclear. To investigate potential determinants of mortality among IDDM patients, a case-control study was conducted. These retrospectively obtained data indicated that shorter relative height at onset, frequent diabetes-related readmissions, the presence of diabetes complications, a family history of diabetes, premature familial mortality, no participation in school team sports, and a lower level of education were related to subsequent mortality among males. Among females, however, a shorter duration of diabetes clinic attendance and the presence of diabetes complications were the only significant associations to mortality.

Effect of iohexol and diatrizoate on pulmonary arterial pressure following pulmonary angiography. A clinical comparison in man.

A clinical comparison of the effects on pulmonary arterial pressure produced by iohexol and diatrizoate, following selective pulmonary angiography, was made in 17 patients with a normal pressure before the injection of the contrast medium. A double blind crossover study was performed and each contrast medium was administered in random order. The pulmonary arterial pressure was continuously recorded before, during and after the injection for 3 minutes. The effect of iohexol on the pulmonary arterial pressure was significantly less than that of diatrizoate. The results indicated that iohexol should be better tolerated than diatrizoate and therefore a safer contrast medium for selective pulmonary angiography.

Effect of iohexol on pulmonary arterial pressure at pulmonary angiography in patients with pulmonary hypertension.

The effects of 300 mgI/ml of iohexol on pulmonary arterial pressure at selective pulmonary angiography were evaluated in seven patients with pulmonary hypertension due to pulmonary thromboembolism. The total number of contrast injections was 26. Pulmonary arterial pressure was recorded before and after each injection. The effect of iohexol on pulmonary arterial pressure in the pulmonary hypertensive circulation was slight. The results suggest that iohexol at 300 mgI/ml may be safe as a contrast medium for selective pulmonary angiography in patients with pulmonary hypertension.

Anterior mediastinal schwannoma: a case report.

The most common neoplasms of the mediastinum are those of neurogenic origin, and the majority of these arise in the posterior compartment. We report a case of benign schwannoma originating in rare location, the anterior mediastinum, and its imaging findings.
