Infantile cerebellar thrombosis: a case of lupus anticoagulants?

Lupus Anticoagulants (LA) pathology is a disease frequently associated with venous and/or arterial thrombosis. The authors describe a 6 year-old boy complaining cephalea and emesis, followed by lethargy, in whom antiphospholipids antibodies were detected. Brain magnetic resonance scans showed lesions of the cerebellum.

[Radiotherapy in the treatment of Merkel cell tumors].

Merkel cell carcinomas are very rare (80 cases up to 1986) and very malignant; they have been known for 20 years only as "trabecular carcinomas". They do not rise from neural crests, and therefore are not apudomas, but from a staminal cell of the skin with neuroendocrine evolution. Merkel cell carcinomas must be distinguished from undifferentiated carcinomas of the skin, lymphomas, and oat cell carcinomas.

Limited small cell lung cancer of the lung treated with combination chemotherapy and radiotherapy: a retrospective analysis.

We assessed the outcome in 65 patients with limited small cell lung cancer (SCLC) treated from 1980 through 1989 with combination chemotherapy and chest and cranial irradiation. Of the 65 patients, 32.3% (21/65) achieved a complete remission (CR) prior to radiation therapy; six additional cases achieved a CR after radiotherapy with an improvement of 10% in the incidence of CR.

The evaluation of effect of radiotherapy on T and B lymphocytes with standard methods and monoclonal antibodies: results at 30 months.

We examined and evaluated the immunologic status of 15 patients suffering from neoplastic, not ematologic, diseases, who underwent external beam radiation therapy. We determined the total lymphocyte count, the percentage of E and EAC rosettes, surface membrane immunoglobulins, the lymphocyte reactivity to PWM and PHA, and T-lymphocyte subpopulations by means of monoclonal antibodies (OKT3-OKT4-OKT8). Besides we evaluated the percentage of LEU7 and OKM1 cells and lymphocytes response to MLR.

[Evaluation of the immune function of patients undergoing radiotherapy: results after 18 months].

The effects of radiotherapy on subset lymphocyte populations of 15 neoplastic patients were studied. The initial impairment of lymphocyte functions, was restored after eighteen months to 78% of initial values. The numerical equilibrium of T and B subpopulations was completely reinstated.
