[Percutaneous endoscopic gastrostomy. Indications and follow-up in 30 patients].

The indications and results of percutaneous endoscopic gastrostomy (PEG) were reviewed in 30 consecutive patients, most of whom had problems of deglutition secondary to the treatment of ENT neoplasia. The procedure was successful in all patients but some difficulty was encountered in 4 cases. There were no major complications or fatalities. The benign complications were all amenable to medical therapy and did not require ablation of the gastric tube. In general, PGE was well tolerated and an easy to use method of nutritional assistance, allowing most patients to gain weight. In the authors' experience, this technique has an important role to play in the nutritional assistance of patients with problems of deglutition due to neurological disease or ENT neoplasia. The relative innocuity of PEG gives it a great advantage over surgical gastrostomy.

[Percutaneous endoscopic gastrostomy. Indications and follow-up in 52 patients].

A nutritional support was indicated in 52 patients, most of whom had deglutition problems linked with post-therapeutic after-effects of neoplasia of the ORL sphere. Assistance was possible in all the cases, with difficulty in 9 cases. There were only three major complication (two of which necessitated the removal of the tube) and no fatalities. Benign, more numerous complications were all medically curable and did not necessitate the removal of the tube. The follow-up of the patients showed remarkable tolerance to, and nonproblematic use of, the GPE tube as a nutritional aid leading, in the majority of cases, to a weight gain, even when ambulatory. Our experience suggests that this technique deserves a prime place as a nutritional aid for cases of deglutition problems, of neurological origin, and in ORL cancers. Its relative safety must undoubtedly make it preferable to the surgical technique.

[Giant cell arteritis and takayasu's disease: histopathological criteria (author's transl)].

Both of these arterial diseases may involve the aorta and the major arterial trunks. Two cases of subclavian involvement are used to contrast them from a histopathological standpoint. In giant cell arteritis, the lesions affect above all the internal elastic layer and the inner part of the media, destroyed by an inflammatory infiltrate with giant cells. In Takayasu's disease, the lesions involve the adventitia, the site of fibrosis and of inflammatory islets with the vasa vasorum at the centres. Involvement of the media is predominantly in its outer part, the internal elastic layer being intact. A histopathological definition of these arterial diseases may be envisaged on the basis of these facts.

[Lesions of the myenterix plexuses in idiopathic chronic intestinal pseudo-obstruction and in certain general diseases].

Recent observation of a case of idiopathic chronic intestinal pseudo-obstruction and the relationship sometimes suggested in this context with certain systemic diseases, such as scleroderma, led the authors to compare the changes seen in the myenteric plexuses in these different groups of disorders. The intramural plexuses were studied using the technique of B. Smith, in thick frozen section parallel to the lumen and stained using Bielchowsky's method. Plexus innervation was normal in a case of digestive amyloidosis and a case of myxoedema. There were secondary changes in the plexuses in scleroderma. The lesions were very different in our case of idiopathic chronic intestinal pseudo-obstruction (marked decrease in the number of neurones with degenerative changes in the neurones and dendrites, marked schwannosis). A decrease in the number of neurones was seen in a case of severe diabetes. Various mechanisms are discussed. These cases emphasize the great value of B. Smith's technique in the fine study of the intramural plexus innervation of the digestive wall.

Immunohistochemical patterns of hepatitis B surface antigen (HBsAg) in patients with hepatitis, renal homografts recipients and normal carriers.

A series of 180, Bouin-fixed and paraffin embedded liver biopsies obtained from 147 patients was investigated for the presence of hepatitis B surface antigen (HBs) by histochemical and indirect immunofluorescence techniques. A comparison between orcein staining and Masson's trichrome preparations for ground glass hepatocytes, showed that immunofluorescence was both the more reliable and the more specific method for detection of HBsAg in liver tissue. The ability to perform this technique on paraffin sections facilitates systematic studies and allows retrospective work-up. IF-HBs positive hepatocytes were found in approximately two thirds of all HBs-positive patients in their serum, but never seen in HBs-negative patients. HBs-positive cells were observed in healthy chronic carriers and in all forms of chronic hepatitis, but never in acute HBs-positive hepatitis. In patients treated with chronic hemodialysis and in renal homograft recipients, the incidence of positive cells was higher than in the chronic hepatitis groups; this could be correlated with the duration of antigenemia at the time of biopsy.
