[Encephalic pseudotumoral toxoplasmosis in the course of blood diseases].
The authors report two cases, the first pathological and the second clinical of pseudo-tumoural cerebral toxoplasmosis, occurring during the course of blood diseases. They refer to the conditions of appearance of this rare complication, with only twenty cases recorded in the literature, during malignant blood diseases. They stress the primordial role of immunological deficiency related either to the underlying disease (especially Hodgkin's disease) or to immuno-suppressive therapy. The clinical picture, with little in the way of typical features, is thus that of a diffuse méningo-encéphalitis. Pseudo-tumoural forms are rare. The authors also stress the minimum conditions required for the validity of the dye test and the value of the diagnosis of cerebral toxoplasmosis. An association of sulphadiazine-purimethamine, active and effective, cured the second patient.

Pulmonary function: relation to aging, cigarette habit, and mortality.
The relation of pulmonary function to aging and cigarette habits has been examined cross sectionally and longitudinally in the Framingham cohort. On cross-sectional analysis, women were found to have lower forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV-1) values than men even after adjusting for height. Their FEV-1 percent was, on the other hand, higher than those of men. As the population aged over 10 years, their FVC and FEV-1 declined 9% to 27% depending upon age and sex. The FEV-1 percent, however, showed a decline only in the older age groups. In a cross-sectional analysis, cigarette smoking showed an inverse association to FVC and FEV-1 percent. Longitudinally, cigarette smokers showed a more rapid decline in FVC in 10 years than nonsmokers. On giving up smoking their FVC became more like that of the nonsmokers. A striking relation of FVC to mortality was noted in both sexes, which is not accounted for by associated cigarette habits.

[Study of neurological manifestations of chronic lymphatic leukemia (lymphosis). Role of associated globulin anomalies (apropos of 8 cases)].
The authors emphasize the relative frequency of neurological symptoms in lymphatic leukaemia. Clinically, these cause more or less diffuse encephalitic or multineuritic syndromes, generally a combination of the two. Their pathogenesis is usually connected with lymphoid tissue infiltration into either the meninges or the vascular sheaths of the central nervous system or the sheaths of the roots or of the peripheral nerves. The authors stress the possible function of immunoglobulin abnormalities of the C.S.F. indicative of the presence of the leukaemic process within the nervous system. This pathogenesis prompts the use of therapeutic methods directly attacking leukaemic infiltration of the nervous system (focal cobalt therapy, intrathecal chemotherapy) and the authors have found that these give favourable results.

[Use of local cobalt therapy in peripheral neuropathies associated with chronic lymphopathies (lymphoses). 2 cases with histo-immunologic and ultrastructural records].
In two cases of peripheral neuropathy, associated with a chronic lymphopathy, cobalt therapy to the lower limbs provided considerable relief of pain, with partial motor recovery. The disappearance after cobalt therapy of the lymphoid infiltrate of the peripheral nerve leads to discussion of the pathogeni role of this infiltrate. Immunofluorescent and electron microscopic studies form the basis of a discussion of the mechanism of involvement of the peripheral nerve non-secreting lymphopathies (chronic lymphoid leukaemia) and in secreting lymphopathies (Waldenström's disease).
