Nerve and muscle microvasculitis in peripheral neuropathy: a remote effect of cancer?

In a series of 50 cases in which nerve and/or muscle microvasculitis was seen on biopsy, seven were associated with malignancy. In two cases, the cancer was found after the discovery of microvasculitis. All patients exhibited sensory-motor neuropathy, which was often painful and asymmetrical, with a progressive course. ESR and CSF protein levels were always elevated. Motor conduction velocity was slightly reduced in three cases, unmeasurable in one case, and normal in three. Cancers involved were adenocarcinoma in five cases (three prostate and two lung), Hodgkin's disease in one and immunoblastic lymphadenopathy in one. A thorough search for cancer should be performed when microvasculitis is seen in nerve or muscle biopsy specimens, especially when ESR and CSF protein levels are elevated.

Investigation of drug interactions with pinaverium bromide.

A series of studies was carried out at 6 centres to investigate possible drug interaction between the spasmolytic, pinaverium bromide, and cardiac glycosides, anticoagulants and hypoglycaemic agents given to patients as part of the long-term treatment of their condition. The results of clinical and laboratory investigations did not show any evidence of pinaverium bromide interfering with the action or activity of any of the drugs studied.

[Malignant arterial hypertension in periarteritis nodosa. Incidence, clinicobiologic parameters and prognosis based on a series of 165 cases].

The authors studied clinical and biological data occurring in 165 patients observed during 23 years and afflicted with polyarteritis nodosa. Hypertension was present in 52 patients (31.5%) and seven of them suffered from malignant hypertension (4%). Mean age of patients (6 male, 1 female), with malignant hypertension was 38 +/- years old. Mean follow up was 49 +/- 28 months including 26 +/- 21 months after discontinuation of treatment of polyarteritis nodosa. Malignant hypertension occurred during the first year of evolution of polyarteritis nodosa. Renal insufficiency was present in 5 of 7 patients. Proteinuria was greater than 1 gr/d in 4 cases. Renal arteriography was performed in 6 patients and showed in every case renal ischemia and microaneurysms in five. In 4 patients measurements of plasma renin activity and of aldosterone were obtained. A stimulation of those hormones was demonstrated. Some symptoms of polyarteritis nodosa were present with a high incidence in case of malignant hypertension: digestive signs (6/7), orchitis (3/6). HBs antigen was present in 6 cases and hepatitis in 5. Captopril was effective in every case, alone or associated with other treatments. Follow up of hypertension went from 8 months to 4 years. At present time 6 patients are alive and one is lost of follow up. A treatment is necessary in 6 of 7 patients. Creatininemia is greater than 300 micromol/l in 4 patients. A successful kidney transplantation was performed in one case. Our study shows a close relation between malignant hypertension observed in polyarteritis nodosa, vascular nephropathy, digestive and urologic signs. Hepatitis B virus could be responsible of those manifestations.

[Treatment of systemic scleroderma with ketanserin. Randomized, double-blind 6-months study of 27 cases].

Twenty-seven patients with systemic scleroderma and Raynaud's phenomenon underwent a randomised double blind therapeutic trial: monotherapy with Ketanserine (80 mg/day for 6 months) against Placebo. The secondary effects were comparable in both groups as were the withdrawals from the trial for aggravation of Raynaud's phenomenon (one in each group). No significant difference was observed between the two groups as regards the evolution of the Raynaud's phenomenon or skin changes. Dysphagia was improved in the Ketanserine group (p less than 0.05) but not in the Placebo group. Some patients in the Ketanserine group experienced an improvement in the Raynaud's phenomenon at the end of the trial period; there were no improvements in the Placebo group. Three haemorrheological parameters (total blood viscosity, plasma viscosity and thixotropism) were abnormal at the beginning of the trial and did not improve by the end in the Ketanserine group. The K infinity coefficient of Quemada's law was normal at the start of the trial and increased after treatment (p less than 0.05).

[Abdominal lymph node tuberculosis: diagnostic value of echography and x-ray computed tomography].

The aspects of abdominal ultrasonography and computed tomography (CT) were studied in 4 patients (3 African and 1 Haitian) with abdominal tuberculosis. All were markedly debilitated and three patients had protracted fever. Tuberculosis was documented in all cases by demonstrating Mycobacterium tuberculosis in cultures of lymph nodes taken during laparotomy and/or cultures of products of gastric aspiration. Ultrasonography showed enlarged lymph nodes in the pancreatic and peripancreatic areas and also in the mesenteric, perivascular and hepatic pedicle areas. CT showed hypertrophied lymph nodes with low tissue density ranging from 20 to 35 Hounsfield units. Although non pathognomonic, these aspects were suggestive of tuberculosis. Intravenous contrast medium administration failed to increase the density in the center of lymph nodes but disclosed the existence of a thick hyperdense rim surrounding the hypodense center of the caseous lymph nodes. Repeated ultrasound and CT examination allowed to control the efficacy of antituberculous chemotherapy.

[Toxoplasmosis and lupus. A review of the literature apropos of 4 cases].

The authors report 4 cases of toxoplasmosis in patients with acute disseminated lupus erythematosus (ADLE). In one case, a pregnant patient with serology indicative of chronic infection, infected the neonate who died of subacute toxoplasmosis. Although ADLE is a classical cause of immunodepression, toxoplasmosis is a rare complication; only 5 cases were found in a review of the literature. Toxoplasmosis infection may resemble an exacerbation of lupus; an accurate diagnosis is essential as the treatment of the two conditions is radically different. The problems of diagnosis of toxoplasmosis in immunodepressed patients are reviewed and the therapeutic approach, especially in pregnant patients, is discussed. In ADLE, the authors recommend checking toxoplasmosis serology before starting and during treatment with corticosteroids. Special attention should be paid to pregnant women with apparently chronic serological changes as neonatal infection may occur.

[Caval thromboses and systemic diseases].

Sixty-five patients presenting with a vena cava syndrome have been examined over a 7 years period; incidence of systemic diseases as an etiologic factor has thus been studied. A systemic disease was diagnosed in 17 cases, that is 25 p. 100 of cases. This incidence is higher in inferior vena cava syndromes (15 cases out of 45). Two diseases appear as the main factors: on one hand, Behçet disease, liable for 8 vena cava thrombosis, 7 inferior and 8 superior thrombosis; on the other hand, severe disseminated erythematous lupus liable for 5 cases of inferior vena cava thrombosis. Other etiologies are mentioned such as: Churg and Strauss disease (1 case), Horton disease (1 case) and hemorrhagic rectocolitis (1 case). In the patients presenting with lupus, two died from various pulmonary embolisms; a vena cava clip was required in 3 cases. As for lupus, the immuno-hepatologic exploration did demonstrate a thrombopenia in 5 cases, an hemolytic anemia with a positive Coombs test in 2 cases, and a circulating anti-coagulant (antiprothrombinase type) in one case. Though high frequency of systemic diseases in this series may depend on the patients' recruitment, systemic lupus as well as Behçet diseases are to be researched in case of vena cava thrombosis, above all if diagnosed in a young patient and failing to be explained by a congenital abnormality of hemostasis.

[Treatment of systemic scleroderma with factor XIII in 86 patients, with long-term follow-up].

Eighty-six patients with progressive systemic sclerosis were given coagulation factor XIII intravenously in different dosage regimens. The mean duration of treatment was 19 +/- 18 months and patients were followed up for 22.9 +/- 18.8 months. Improvement or stabilization of the lesions was obtained in 44/86 patients and exclusively concerned skin lesions; there was no improvement in visceral lesions. The drug was well tolerated in short-and long-term treatment. It is concluded that factor XIII demonstrated lasting effectiveness in one-half of the patients treated.
