[Small cell lung carcinoma in the form of multiple lung nodules]. / Carcinoma pulmonar de células pequeñas en forma de nódulos pulmonares múltiples.

Small cell carcinoma of the lung occasionally presents as a single pulmonary nodule, but its expression in the form of multiple pulmonary nodules has not been reported in the literature. We describe a single case of small cell carcinoma of the lung presenting as multiple pulmonary nodules that seems to have been cured by chemotherapy.

[Measurement of pulmonary function in laryngectomized patients]. / Medición de la función pulmonar en pacientes laringectomizados.

Comparative study upon clinic, radiological and spirometric parameters in 30 laryngectomees, which were spirometric tested by means of a device either simple, cheap, speed and efficient, designed by the AA. These are the conclusions drown out: 1st. There is a poor correlation clinic-functional in patients with obstructive pathology (which command, in the AA's opinion an exploration of the respiratory function in all laryngectomees). 2nd. On the contrary, there are a good radiological and functional correlation in patients suffering for restrictive disease (here the assessment functional means the quantification of the restrictive process). And 3rd. The laryngectomees show a higher functional affectation and can be expected if related to the age and sex. The explanation is to be found in the intercurrent diseases and also in the infections following the larynx removal.

[Anti-DNA determination using Crithidia luciliae. Specificity and clinical usefulness in systemic lupus erythematosus]. / Anti-DNA par Crithidia luciliae. Spécificité et utilité clinique dans le lupus érythémateux systémique.

The authors determined the existence of native anti-DNA antibodies by the crithidia lucilae (anti-DNA-CL) test in 44 patients suffering from systemic lupus erythematosus (SLE), 48 with rheumatoid arthritis (RA), 12 with scleroderma, 8 with polymyositis and/or dermatomyositis, 12 with mixed connective tissue disease, 53 with chronic liver disease and 100 blood donors in order to establish the specificity of the test in SLE, its possible correlation with the degree of clinical activity and the presence or absence of neuropathy, and its possible use in the therapeutic control of the disease. The presence of anti DNA-CL was specific to SLE. It was seen at significant titres only in patients with active disease. Anti DNA-CL antibodies capable of activating complement were seen more frequently and at higher titres in cases with active nephritis. In longitudinal studies it was seen that clinical activity or inactivity were associated with parallel oscillations in anti DNA-CL titres. These data confirmed the specificity of the method and its usefulness in the diagnosis and therapeutic control of the process.
