The authors describe the case of a pulmonary interstitial fibrosis, the discovery of which preceeded the skin and muscular manifestations of dermatomyositis which was confirmed by a muscular biopsy. The aetiopathogenesis of the pulmonary disorder is not well known, nevertheless an immunological mechanism demonstrated in the experimental myositis is suggested but has yet to be proved.

Three cases with eosinophilic infiltration of fascia and muscle are described. In every case at least one relapse occurred. One patient exhibited clinically the definite features of eosinophilic fasciitis. About two cases a tentative diagnosis of Shulman's syndrome is discussed. In these patients, all known causes of eosinophilic myositis had been excluded.

Among 2175 patients seen over the last three years in a non-specialized department of internal medicine with no intensive care unit, 100 had supranormal serum lactic dehydrogenase activities. These patients' case-reports have been analyzed. Nearly half the patients (47/100) had a malignant disease (cancer or hemopathy). Among the remaining patients, 19 had a hepatic disorder (alcohol hepatitis in 10, viral hepatitis in 8, and isoniazide hepatitis in 1), 7 had a heart disease (heart failure with hepatomegaly in 5, myocardial infarction in 2), and 27 had various other conditions (including hemolysis in 6 and polymyositis en 3). The value of serum LDH assay is obvious in situations other than acute conditions such as myocardial infarction of pulmonary embolism; these are better known and have not been studied here as their prevalence was low among the patients enlisted in our study. In comparison to other enzymes (alkaline phosphatase (AP), gamma-glutamyl transpeptidase (GGT), transaminases (GOT, GPT) that were also routinely assayed in our patients, abnormal serum LDH activities are much less common and their significance is quite different. An increase in serum and their significance is quite different. An increase in serum LDH activity indicates a serious condition, often with a fatal outcome. The "various other conditions" group includes patients with hemolysis, hepatitis and myositis; the other patients in this group either had severe infectious diseases or died suddenly in the first few days of their hospitalization before diagnosis had been established. Each etiologic group has been analyzed to asses the characteristics of patients with increased LDH activity according to each etiology. Analysis of coincident abnormalities of the other enzymes listed above shows marked differences between etiologic groups; diagnostic accuracy can thus be enhanced in certain conditions. Most patients with malignancies had poorly differentiated tumors, with metastases: 28 had an epithelial tumor, with hepatic and/or bone metastases in 23 cases, 5 had cancer of the liver, 10 had a malignant hemopathy (2 lymphomas, 5 myeloproliferative syndromes, 3 acute leukemias), and 4 had a sarcoma. Cancer of the lung is the most common malignancy (10 cases) and may be responsible for increased serum LDH activity even in patients without metastases. Serum LDH assay is of value for monitoring the course in patients with initially increased activities as it falls under effective therapy and rises during exacerbations.

Third, fourth and sixth cranial nerve palsy is a less common complication of giant cell arteritis than ischemic optic neuritis. Nevertheless, it occurs in at least 10% of cases. A case of giant cell arteritis with third nerve palsy which resolved under corticosteroid therapy is reported. The incidence of ocular complications is assessed from a review of the cases previously seen in the department and of data from the medical literature. The authors believe that the index patient has ischemic neuritis rather than myositis. It is concluded that giant cell arteritis should be considered at an early reversible stage.

High toxoplasma antibody titers have been reported in polymyositis and other connectivitis with myositis. The authors describe a case of systemic lupus erythematosus with polymyositis and high titers of IgG toxoplasma antibodies. Studies of muscle biopsy specimens by immunofluorescence and inoculation of mice with muscle extracts failed to demonstrate the presence of Toxoplasma gondii. The nature of the toxoplasmic agression is discussed. It may be that reactivation of a previous infection due to the rupture of cysts was promoted by the immunologic disorders and complement deficiency related to systemic lupus erythematosus.
