The relationship between idiopathic portal hypertension (IPH) and extrahepatic portal vein thrombosis (EPVT) remains controversial. In a retrospective study, we compared the clinical features of 21 patients with IPH, 27 with EPVT, and 38 with liver cirrhosis (LC). The variables with statistical difference between IPH and EPVT were age (38 +/- 17 years versus 29 +/- 14, respectively; p < 0.05), and 5-year survival (72 versus 92%, respectively; p < 0.05). The other clinical and laboratory variables had similar distribution in IPH and EPVT. LC patients were older than those in the other groups (48 +/- 13 years, p < 0.05), and had a poorer 5-year survival (60%, p < 0.05). Furthermore, LC patients had clinical features of liver failure in a higher proportion than the other groups did. The results suggest that IPH, EPVT, and LC are separate clinical entities.
An approach to the origin of those diseases of the stomatognathic system which occur within the laboring media and may thus pose an occupational hazard to workers, is hereby attempted with the aim of creating consciousness in dentists as to the importance of occupational stomatology within the odontological field, in the hope of motivating them to explore and research further in the study of these pathologies.

A case of dilated cardiomyopathy arose after a spontaneous abortion at the second month of pregnancy is reported. Whereas clinical, hemodynamic and gross features pointed to a diagnosis of right ventricular cardiomyopathy, histologic findings of inflammatory infiltration, myocyte degeneration and interstitial fibrosis of the atrial and ventricular walls allowed to a correct diagnosis of chronic myocarditis.
