Calcificaçöes pancreáticas em crianças tem sido descritas com pouca frequência, sendo a associaçäo com ingestäo crônica de álcool ainda mais rara. Os autores apresentaram o caso de uma criança de nove anos de idade com calcificaçöes pancreáticas e dores abdominais recorrentes, causadas pela pancreatite crônica alcoólica. Essa etiologia foi determinada por anamnese, dados epidemiológicos, exames laboratoriais e diagnóstico por imagem

The authors study 25 steatotic or congested livers by means of post-mortem cholangiographies and vinyl moulds of the bile ducts. They show that the bile ducts of these organs present alterations, characterized by stretching, rectification, and lengthening of the intra-hepatic bile ducts, as a consequence of the diffuse hepatomegaly that occurs in the disease. They relate the average number of straight ducts in the intra-hepatic bile tract to the extension of the extension of the disease, obtaining a positive relation. A statistical evaluation of the results was made, allowing objective conclusions.

The authors suggest a new methodology for the study of the intrahepatic portal system, using atmospheric air as a contrast medium. They used 48 livers of normal and pathological corpses, obtaining post-mortem cholangiographies and vinyl molds. Comparing the images obtained with literature data and with the vinyl molds, the authors conclude that the method is accurate, presenting furthermore many advantages with regard to contrasts generally used, such as low cost, easy performance, possibility repeating the radiographs as many times as necessary, and the possibility of simultaneous obtaining contrasts of other intra-hepatic systems by use of other radio-opaque contrast media in another system, as for example the biliary or the arterial system.

The authors study 14 cirrhotic livers by means of post-mortem cholangiography and vinyl casts. They analyze the radiographs according to thorough criterions, described in the text, and come to the conclusion that intrahepatic biliary ducts in cirrhotic livers present serious alterations, represented by distorted ducts with focal stenoses, nodular impressions, wall irregularities, increase of the number of obtuse angles and poor peripheral filling, which confer a disharmonic aspect to the intra-hepatic biliary ducts of these organs. Furthermore, they show that livers with post-necrotic cirrhosis present bile ducts much more seriously damaged than those with Laennec's cirrhosis. The paper was submitted to statistical analysis and allows objective conclusions.
