[Inoperable brain metastases from bronchogenic cancers. Value of combined chemotherapy with cisplatin and 5 fluorouracil].

We report the results of a combined of chemotherapy with CDDP and 5 FU repeated every 3 weeks in sixteen men (age range 31-73 years) with brain metastases. CT was performed after 2, 4 and 6 cycles to assess efficiency. Response was considered complete when no lesion was found on the CT scan and partial when the lesion shrunk to least half its the total volume. After two cycles, the response rate was 8/16 (50%). Treatment toxicity was mild with only one case of severe but reversible myelotoxicity (grade III). CDDP and 5 FU combined chemotherapy can be a useful treatment for brain metastasis of lung carcinoma.

[Chemotherapy with cisplatin and 5-fluorouracil in inoperable brain metastases of bronchopulmonary cancers].

Chemotherapy is not a common treatment for cerebral metastases. The authors report results of combination chemotherapy with cisplatin (CDDP) and fluorouracil (5-FU). Sixteen men (age range 31-73 years) with brain metastases were treated with CDDP 20 mg/m2/day in continuous infusion for 5 days (d 1-5) and 5-FU 1 g/m2/day in continuous infusion for 4 days (d 1-4), and the treatment schedule repeated every 3 weeks. A brain computerized tomography after 2, 4 and 6 cycles was performed to assess efficacy. It was considered that complete response was achieved if no lesion was found on the CT scan, and partial response if at least half of the total volume had decreased. After 2 cycles, the response rate was therefore 8/16 (50%). Treatment toxicity was very mild with only 1 case of severe but reversible myelotoxicity (grade III). It is concluded that chemotherapy combination with CDDP and 5-FU is a useful treatment for brain metastasis of lung carcinoma.

[Value of ipratropium (Atrovent) in the treatment of chronic obstructive lung diseases in myasthenic patients treated with anticholinesterase agents. Apropos of a case].

We report a case of myasthenia gravis occurring in a 70-year old patient with old chronic bronchitis. Anticholinesterase therapy led to an increase in respiratory symptoms, but relief was obtained with inhaled ipratropium. The activity of this drug was confirmed by spirography. This clinical finding is compared with similar data found in the literature.

[Mucoviscidosis: current diagnostic possibilities. Applications in perinatology].

The gene of cystic fibrosis is localised on the long arm of chromosome 7. DNA probes placed close to the gene enable a study of restriction polymorphism to follow the transmission of the gene in index families. It is now possible to counsel those families, who already have an affected child, with an early antenatal diagnosis at ten weeks after the last period. In our personal experience, based on a study of the genotype of 48 families, 70% were informative when they were studied by two probes corresponding to the local pJ3.11 and met. When the latter probes Km19-XV2c were studied concurrently useful information was achieved in 96%. DNA analysis non enables the detection of the chromosome carrying the deleterious gene in practically every family where there is a child suffering from the disease.

[Pseudotumoral amyloidosis of the lung].

We report a case of pseudo-tumoral pulmonary amyloidosis in which the diagnosis was achieved by a transbronchial biopsy and ultimately confirmed by a necropsy examination of the lung. The lung disorder was isolated without any co-existing disturbance of the immunological system.

[Malignant endobronchial melanoma, apparently primary. Apropos of a case].

This case concerns a 48 year-old patient whose endobronchial malignant melanoma was discovered on the occasion of a haemoptysis. A search for primary localization remained negative, suggesting a primary endobronchial lesion. Only a few cases of endobronchial malignant melanoma have been published, and several assumptions can be raised to explain the possibility of their primary origin.

[Fatal acute pneumonopathies in disseminated lupus erythematosus].

Two cases of systemic lupus erythematosus (SLE) complicated by pneumonia which resulted in death are reported. The first patient, a 21-year old woman, died of acute diffuse lupus pneumonia; the initial and unusual radiological image of "multiple balloons" progressed within 2 months to terminal interstitial fibrosis. The second patient, a 60-year old woman, died of infection on an interstitial pneumonia which turned into severe fibrosis within 16 months. Acute or chronic lupus pneumonia is uncommon, but it may follow a very serious course. Clinically, true lupus pneumonia must be distinguished from all other types of lung involvement in SLE, such as infection, pulmonary haemorrhage or oedema, iatrogenic pathology, thromboembolic disease, etc. The pathogenetic mechanism of pulmonary lesions directly related to SLE is obscure, although some lung biopsy specimens have shown positive immunofluorescence. Concerning treatment, the initial response to corticosteroid therapy is usually very good, especially in the acute forms of the disease. However, in severe cases immunosuppressive drugs or even plasma exchanges must be added to steroids. For treatment to be rapidly initiated the diagnostic procedures must be completed in the early stages of the disease, involving, when necessary, surgical lung biopsy.

[A new case of associated sarcoidosis and tuberculosis, or the close relationship between 2 granulomatous diseases...].

The case reported here concerns a 30-year old male patient who had both very severe, multivisceral tuberculosis and equally severe sarcoidosis, with repercussions on the respiratory function that required corticosteroid therapy. Prolonged anti-tuberculous therapy and corticosteroids gave favourable results. This case is remindful of an old debate which opposed the two diseases on account of their histological lesions. It offers a new example of the severity of tuberculosis in "immunocompromised" patients, and it raises anew the still unresolved problem of the individuality of sarcoidosis in pulmonary pathology.

Predictive value of T-cell subset derangements in lung cancer.

The proportions of T-lymphocytes, T-lymphocyte subsets, NK cells, DR determinant and interleukin-2 receptor-bearing T-lymphocytes were enumerated in 39 patients with lung cancer prior to any chemotherapy. T-lymphocytes, suppressor/cytotoxic T-cells and interleukin-2 receptor-bearing T-cells were found to be significantly higher in patients responding than in those not responding to chemotherapy. Such mononuclear cell subset analysis by monoclonal antibodies might be additional information to consider before undertaking treatment.

[Peripheral neuropathies during treatment with cisplatin: clinical and electrophysiologic study of 11 cases].

Eleven patients with bronchial epidermoid carcinoma and undergoing treatment with cis-D.D.P. (II) were kept under electrophysiological and clinical surveillance. No other neurotoxic medication was added. The total dose of cis-D.D.P. was 300 mg/m2 over a period of three months: namely, three courses of 100 mg/m2 distributed over 5 days. Following the pretreatment check-up, the patients were divided into two groups: those without any electrophysiological abnormality (group A), and those without clinical abnormality but with a delayed latency H of the Hoffmann Reflex (group B). Patients in group A showed a slowing down of the motor nerve conduction velocity of the Median and Peroneal Nerves after a course of 100 mg, without accompanying worsening of the conduction velocity after 300 mg/m2, and prolongation of the distal latency of the sensory Median Nerve after 300 mg/m2; in group B, no significant change of electrophysiological clinical features were noted. In the two groups a non-significant reduction in amplitude of evoked responses were noted. These findings are more consistent with an axonal injury than with functional myelin injury. The authors review the existing literature and discuss the physiopathologic mechanisms of cis-D.D.P. peripheral neuropathies.
