[Value of video-assisted thoracic surgery in internal medicine. Apropos of 7 cases].

Since a few years, the medical thoracoscopy has already been used specially for the diagnostic and therapeutic taking up of the pleural pathology. Behind it, the video-assisted thoracic surgery has been improved since 1990. As a surgical technology, it proved its interest refering to the classical thoracotomy by lessening operative morbidity and mortality. The authors discuss its main indications about seven cases, recruted in the internal medicine service and operated in the thoracic surgery service of the Val-de-Grâce hospital. Some of these indications are now admited by most of the authors: 1) diagnostic aims: pulmonary biopsy in case of interstitial pathology, of pulmonary peripheral under-pleural nodule and sometimes of solid tumors of the mediastinum, specially of some lymph-nodes. 2) Therapeutic aims: the spontaneous pneumothorax treatment of the adult remains the most classical indication; the thoracic sympathectomy, the creation of pleuropericardial windows and the resection of benign tumors of the mediastinum are now well acknowledged indications.

[Simultaneous hepatic cholangiocarcinoma and bone fibrosarcoma 45 years after ingestion of Thorotrast].

This case of a 63 year old man reports the simultaneous development of hepatic cholangiocarcinoma and fibrosarcoma of the sacrum 45 years after the systemic injection of Thorotrast. The characteristic radiologic aspect was an important criteria for diagnosis. Biopsies have confirmed the histology of both tumors. We describe the way to thorotrastosis diagnosis and characteristic malignant tumors, especially cholangiocarcinoma, induced by Thorotrast.

[Acute myelitis after vaccination against hepatitis B].

A 56-year old man was hospitalized for spasmodic paraparesis with sphincter disorders. After exclusion of spinal cord compression and all other inflammatory, infectious or neoplastic causes, the possibility of a connexion with an hepatitis B vaccination performed with a recumbent vaccine three weeks before the neurological disorders appeared was considered. The pathogenesis of such a myelitis remains uncertain. It is based on the possible reactivation of a dormant virus or a crossed antigenic reaction between a protein of the vaccine and the nervous system. The course of the disease is usually favourable. The frequency of this complication would be more accurately determined if all neurological manifestations occurring after hepatitis B vaccination were reported.

[Viral hepatitis in patients over 60 years of age. Clinical, etiologic and developmental aspects].

The authors report a retrospective study of 78 cases of acute viral hepatitis observed from 1971 to 1985 in patients over 60. Viral hepatitis involved males as often as females. A, B, delta and non-A, non-B viruses were responsible for 11.5, 23.1, 5.1 and 60.3 p. cent of cases, respectively. From 1975 on, the frequency of non-A non-B viral hepatitis has reached 85 p. cent while blood transfusions appeared as the most important route of transmission. Outcome was severe in 10.3 p. cent of cases. Early in the course of disease, the risk of progression to cirrhosis was obvious and concerned 12 patients (1 out of 18 with B hepatitis, 3 out of 4 with D hepatitis, 8 out of 47 non-A non-B hepatitis). The long term prognosis (from three to five years) was not as poor as stated in previous studies.

[Hepatic manifestations in Still's disease].

In children, as in adults, Still's disease usually presents with a hectic fever, a characteristic rash and arthralgia or arthritis. Visceral involvement is however classical; the hepatic manifestations were studied with respect to two cases. Biochemical changes are common, often mild: the commonest abnormality is cytolysis. Jaundice is less frequent and hepatic involvement may in exceptional cases be life threatening, usually in cases of serious polyvisceral disease often with disseminated intravascular coagulation. These manifestations may be spontaneous or secondary to salicylate therapy; the anatomical changes are the same; the salicylate would therefore seem rather to unmask and aggravate an underlying hepatic abnormality.

[Hepatic amebiasis: study of 152 cases].

The purpose of this study was to describe and analyse retrospectively the clinical, serological, anatomical and evolutive features of 152 cases of hepatic amebiasis in young adults, treated and followed up in France from 1969 to 1983. The disease was revealed 3 times out of 4 by tender hepatomegaly with fever, but only in 6 cases by complications. Serological tests (immunofluorescence or hemagglutination) were always positive for amebiasis, whereas Entamoeba histolytica was absent from stools in 96.7 p. 100 of the cases. Hepatic amebiasis always caused a hepatic abscess: in these cases, the superiority of ultrasonography over all other diagnostic methods was confirmed, especially concerning the detection of multiple abscesses (47 p. 100). Complete recovery was obtained by medical treatment in 117 cases, either alone (98 cases), or combined with needle aspiration (19 cases). Nitro-imidazoles are the simplest treatment, but nevertheless in 5 cases they were not effective. These patients were then treated with dehydroemetine, associated in 2 cases with surgery. Four patients relapsed at mid or long-term after apparent recovery, in the absence of any obvious reinfection. A significant correlation between the course of the treated disease and the size and number of abscesses was demonstrated: it was possible to define a group characterized by a slow and/or complicated course (with single abscess of the right lobe whose diameter is equal to or greater than 10 cm, or multiple abscesses). The pathogenesis of hepatic amebiasis is not yet fully understood.

[Yellow nail syndrome with chylous effusions].

Yellow nail syndrome is characterized by a yellow discolouration of the nails associated with idiopathic lymphoedema and pleuropulmonary manifestations. Pleural effusions are usually of the exudate type with a normal lipid content. The case reported here of a 74-year old man who had yellow nails together with chylothorax and chylous ascites provides an opportunity to discuss the origin of these rare effusions which, like the syndrome itself, were most probably due to primary abnormalities of the lymphatic system.
