[Angiodysplasia of the colon and Crohn's disease. A study with vascular resin casts]. / Angiodisplasia de colon y enfermedad de Crohn. Estudio con moldes vasculares de resina.

All the previous studies which have associated arteriovenous malformations of the colon with chronic inflammatory disease have always been performed on a diseased intestine. This study, which uses the intravascular injection of resin, shows morphological evidence that angiodysplasia of the colon and intestinal inflammatory disease can coexist independently. This fact suggests that in cases of severe hemorrhage in a patient with inflammatory disease of the small intestine, it cannot simply be assumed that it originates in the macroscopically abnormal intestine, and that angiographic examination is a wise measure to rule out the possibility of arteriovenous malformations in the "normal" intestine.

Tumores de la glándula parótida: semiología ecográfica / Tumors of parotid gland: echographical semiology

Los tumores de las glándulas salivales son relativamente raros. Su diagnóstico se realiza mediante el estudio anatomopatológico de la pieza de exéresis. No obstante, la ultrasonografía con escala de grises, constituye un importante método de diagnóstico y relativamente nuevo, cuando nos referimos al estudio concreto de los tumores situados en las glándulas salivales. En el presente trabajo, los autores describen la semiología ecografíca de dichos tumores en 18 pacientes, que comprende la serie estudiada en el Hospital Clínico Universitario de la Facultad de Medicina de Valencia. Así mismo, se discuten nuestros resultados con los obtenidos por otros autores y se practica una exhaustiva revisión de la bibliografía pertinente

[Hepatic adenoma caused by contraceptives. Presentation of a case]. / Adenoma hepático por anticonceptivos. Presentación de un caso.

PIP: A case of hepatic adenoma associated with oral contraceptive (OC) use in a 34-year old housewife is described. The patient presented with transient headaches which were experienced primarily on waking in the morning and were not alleviated with common analgesics. Hypertension was observed. Arteriographs of the kidneys were normal, but a hypervascularized zone in the liver was discovered. The patient, an emotional woman who habitually took sedatives for sleep, had used Neogynon OCs for 8 years. Most other findings were normal. The patient was treated with 20 mg Apresoline and 30 drops of Hydergina/day. After the suppression of the OCs, the patient's condition was favorable, with normal blood pressure of 120/80. The tumor was removed. Radiographic films and microscopic findings are reproduced. The tumor was clinically asymptomatic and was discovered by chance during an evaluation of hypertension. Until the intervention there was no hemoperitoneum. Because of the surgical intervention it was not possible to determine whether the tumor would have regressed after discontinuation of the OCs, as sometimes reported.^ieng
