[Multiple cholesterol embolism mimicking periarteritis nodosa].

Ten men aged 56 to 84 were hospitalized with a diagnosis of periarteritis nodosa, whereas they had multiple cholesterol embolism. The diagnosis was corrected post mortem in the first 3 patients and subsequently in live patients. The particularly misleading clinical manifestations were neurological (polyneuritis in 5 cases, mononeuritis in 1, central nervous system disorders in 3), pulmonary (alveolar haemorrhage in 2 cases, respiratory failure of unknown mechanism in 4) and pericardial (2 cases). Five patients had eosinophilia (more than 500 eosinophils/mm3). The elements that led to the correct diagnosis were the presence of vascular risk factors in all 10 patients (but hyperlipidaemia in only one), severe complications of the atheromatous disease in all cases, a precipitating or aggravating factor in 8 patients (anticoagulant therapy in 7, arteriography in 6) and the finding of purple or necrotic toes (6 cases). Histological (5 cases) and/or ophthalmological (2 cases) evidence was obtained in only 6 patients. Seven patients died 1 to 3 years after the onset of the disorders. Studies on low-density lipoprotein metabolism are in progress to determine the mechanism of clinical manifestations unexplainable by embolism.

[Stauffer's syndrome caused by a benign intracystic renal hematoma].

We report a case of Stauffer's syndrome, characterized mainly by cholectasis, that occurred in a patient with benign intracystic renal haematoma and subsided after nephrectomy. Stauffer's syndrome was recognized, in 1961, as a paraneoplastic manifestation, usually associated with hypernephroma. This syndrome has been reported in only 2 cases of benign renal disease, which was a pseudotumoral xanthogranulomatous pyelonephritis.

Centrofacial malignant granulomas. Clinicopathologic study of 40 cases and review of the literature.

An important problem in the treatment of centrofacial ulcerations is to establish a precise diagnosis, since similar clinical and microscopic findings can result from many different causes (as in the centrofacial malignant granuloma syndrome [CFMG]). A comprehensive surgical biopsy protocol (known as SNFMI/GMCF), involving microbiology, parasitology, immunology and pathology laboratories, allowed us to evaluate and to treat 40 cases of CFMG, who form the basis of this report. In 13 of them, specific diagnoses were found and curative treatments could be given. In the remaining 27, the optical microscopy pattern met the criteria for CFMG without identifiable origin or the presence of so-called lethal midline granulomas; however, a more precise evaluation with the help of immunofluorescence studies led to the recognition of malignant lymphoma (ulcerative lymphoma of the midface [ULM]). Most of these lymphomas belonged to the T cell lineage; the others were of B lymphoid origin, or, more rarely, of histiocytic origin. Patients with ULM received radiotherapy and chemotherapy with a response rate of 70.3%; however, the toxicity was significant, with frequent occurrence of chemotherapy-induced neutropenia followed by severe infectious facial cellulitis. Six patients were enrolled in a preliminary open trial of treatment with recombinant alpha-2b interferon with little success. Three patients were treated with radiation therapy only, and survived. Thus, CFMG is a syndrome with specific causes and treatments, requiring multiple extensive biopsies to make the correct diagnosis. The recognition of ULM as the cause of the previously called "lethal midline granulomas" leads logically to the use of chemotherapy with growth factors in order to ameliorate its bad prognosis.

No evidence for a spirochaetal origin of localized scleroderma.

We looked for evidence of a Borrelia infection in 15 patients with morphoea. We were not able to detect antibodies to Borrelia burgdorferi in any of these 15 patients. None of the 14 skin biopsies examined by immunohistochemistry showed evidence of spirochaetes. Skin biopsies were cultured in 10 patients. All were negative. These results do not support a spirochaetal origin of localized scleroderma.

Cerebral venous thrombosis in Behçet's disease: clinical study and long-term follow-up of 25 cases.

Among 250 patients with Behcet's disease, we describe 25 cases of angiographically proven cerebral venous thrombosis. Intracranial hypertension was the most frequent manifestation. Two initially untreated patients relapsed. Treatment of cerebral venous thrombosis consisted of combined heparin and steroids in 19 patients, steroids alone in three, and heparin alone in three others. Neurologic symptoms improved rapidly in all. Nineteen patients received long-term anticoagulation, and two received aspirin. Relapse of cerebral venous thrombosis or development of optic atrophy did not occur in treated patients. Partial or total recanalization of the occluded sinus was frequent. After more than 3 years of follow-up, the prognosis of dural sinus thrombosis is satisfactory.

[Objective evaluation of sclerodermic skin using the slip-test. Results and validation with 30 patients and 60 controls].

The slip test is a non-invasive way to objectively evaluate the extent of scleroderma by measuring the "slipping" of the skin over an underlying bone. The results obtained in 30 scleroderma patients and 60 controls (178 tests due to multiple measurements) were analyzed to determine which test sites show a significant difference between patients and controls (Student's t-test) and which sites are the most discriminating for the diagnosis of the disease (multivariate analysis). Patient values were clearly distinct from those of controls. The best sites (defined by p < 0.05) were: the mandible, the second and first phalanges of the middle finger, the hands, the forearms, the epicondyles, the sternum, the iliac crests, the patellae, the tibias (the upper and lower fourths) and the feet; in all, 23 sites to which can be added the opening of the mouth (measurement of the maximal interlabial distance), which proved to be a reliable parameter. Multiple regression analysis yielded an equation that identified patients with scleroderma based on 4 variables (right forearm, right iliac crest, sternum and right rib). The slip test is thus the first reproducible quantitative test able to confirm and quantify clinical impressions in scleroderma. It is entirely able to objectively monitor the evolution of the disease under treatment. Nevertheless, complementary studies are needed to verify whether the slip test, which can be performed in 20 minutes during an office visit, can be used advantageously in the routine clinical evaluation of scleroderma.

Polyarteritis nodosa related to hepatitis B virus. A retrospective study of 66 patients.

In an attempt to establish the characteristics, circumstances leading to infection and development of polyarteritis nodosa (PN) related to hepatitis B virus (HBV), prognostic factors and outcome, and to define the most effective treatment, 66 patients observed between 1972 and 1989 were analyzed. Hepatitis was clinically present in 19/66 patients before PN. In most cases, PN occurred less than 6 months after infection. Clinical manifestations of PN were comparable to those observed in patients without HBV infection except for orchitis which was present in 13.6% and for pulmonary signs which were absent. Transaminases were normal in 38 cases for SGOT and 31 for SGPT and twice the normal range or more in the other cases. Antineutrophil cytoplasmic antibodies (ANCA) were tested in 22 patients and present in 2 (9%). Twenty-eight patients were treated with prednisone +/- oral cyclophosphamide +/- plasma exchanges. Thirty-eight patients were given a short-term treatment with prednisone followed by the association of vidarabine, 15 mg/kg bw/d for one week and 7.5 mg/kg bw/d for 2 weeks, and plasma exchanges: 14 sessions during the 3 weeks of vidarabine infusion, then tapered until stopping treatment after 2 to 3 months depending upon the clinical results obtained. The mean duration of follow-up was 50.3 +/- 46.1 months. At the end of follow-up, 13 of the 28 patients (46.4%) treated with steroids +/- cyclophosphamide +/- plasma exchanges died and 7/38 (18.4%) of those treated with vidarabine and plasma exchanges (p < 0.001) died. HBe/anti-HBe seroconversion was observed in 2 patients treated with prednisone +/- cyclophosphamide +/- plasma exchanges who were alive at the time of final analysis and in 16 patients receiving the other regimen. The outcome of patients treated with a few days of prednisone, vidarabine and plasma exchange was good and, therefore, we propose this protocol as the first viable treatment for polyarteritis nodosa related to HBV, surpassing the conventional treatment with steroids and cyclophosphamide, which stimulates viral replication.
