Preoperative chemotherapy in epidermoid bronchogenic carcinoma.

Palliative chemotherapy in cases of epidermoid bronchogenic carcinoma, initially judged to be inoperable, made it possible to perform operative resection in 50 cases. An association of cis-platinum and bleomycin was used, this combination having previously been considered synergistic. In certain cases the tumour seemed to have disappeared on macroscopic examination of the resected specimen, and in some instances no tumoral cells could be found on histological examination. This series brought out several positive features: chemotherapy made it possible to operate on patients previously judged to be inoperable; it ensured maximum local efficiency of drugs because of the absence of abnormal vascularity; and it made it possible to anticipate the cure of occult metastases. However, three negative aspects were also present: modification of postoperative TNM classification making it difficult to establish a prognosis; difficulty in determining therapeutic strategy for pNo; and inadequate long-term follow-up. On the whole the positive points appeared to outweigh the negative aspects, but a randomized study is necessary to confirm this.

[Pulmonary arteriovenous aneurysm].

A case of large arteriovenous aneurysm in the right upper lobe of a 27-year old man is reported. The pulmonary angioma was responsible for a 30% shunt with hypoxia and polycythaemia but was only discovered while looking for the origin of a cerebral abscess. A few weeks after surgical treatment of the cerebral abscess, the right upper lobe was excised with immediate correction of the hypoxia. This case shows that pulmonary angiomas can sometimes be revealed by neurological complications, and that visceral angiomas should not remain undiagnosed. They should be considered as part of a Rendu-Osler disease, the familial character of which may contribute to an early diagnosis.

[Poisoning by diazomethane inhalation].

A case of Diazomethane intoxication has been reported. Diazomethane is gaz commonly used by pharmacological and industrial chemist. This case of intoxication is rare, since only 15 other cases have been published up to now. A review of the literature leads leads describe the clinical feature of such an intoxication by gaz inhalation. When Diazomethane is inhaled it induces respiratory and general disorders. In some cases, it be fatal, and, in some other cases, when a second exposure happens, bronchial asthma may appear. Post mortem studies show pulmonary oedema lesions with important inflammatory reaction localized in the peribronchia. It must be emphasized that direct aggression is probably responsive of toxical discorders, but increase of the symptoms consecutive to a second exposure are related to allergical mechanisms.

Sarcoidosis. Retroperitoneal fibrosis, renal arterial involvement, and unilateral focal glomerulosclerosis.

In one patient with pulmonary sarcoidosis, hypertension occurred during the course of the disease. Aortography showed extensive narrowing of the right renal artery. Surgical exploration disclosed extensive periaortic and perirenal fibrosis. This fibrosis encircled the right renal artery and caused extrinsic compression. Pathological examination disclosed a large amount of histiocyte epithelioid infiltration in various samples of the fibrosis and particularly in the adventitia of the renal artery, highly suggestive of sarcoidal angiitis. Surgical biopsy was performed on both kidneys. The right kidney, protected by arterial stenosis, was little altered, while the left kidney showed extensive interstitial, tubular, and glomerular lesions. The glomerular lesions were focal and segmental hyalinosis.

[Respiratory function disorders during hepatopathies with immunity involvement].

A respiratory functional test was done systematically on 24 patients with chronic hepatitis and was found normal in only 2 cases. It showed an alteration of the transfer in 14 patients and a syndrom of hyperinflation in 8 others. Despite the histopathological proof it seems that the transfer alteration could be attributed to diffuse interstitial pulmonary lesions. They have already been noted in chronic hepatitis by several authors. The pathogeny of this interstitial involvement probably implied immunity phenomenons including the participation of the antigen Australia or others. As for the hyperinflation syndrome observed in 4 patients in the absence of any bronchopulmonary history, it could reveal an emphysema, which, so far, had not been seen associated to chronic hepatitis.

[Study of P50 and 2,3-diphosphoglycerate in 23 bronchoemphysema patients as a function of hypoxia and hemoglobin concentration].

2,3-DPG and P50 were measured in 23 patients with chronic obstructive lung disease. All patients had a chronic hypercapnia (PaCO2 greater than or equal to 45 Torr). They are shared in 3 groups, according to hemoglobin content [Hb] and hypoxia : group I(PaO2 = 48.0 +/- 2.4 Torr ; [Hb] = 15.9 +/- 0.3 g. 100 ml-1; n = 9), (M +/- 1 SE); group II (PaO2 = 46.4 +/- 5.0 Torr; [Hb] = 11.6 +/- 0.7 g. 100 m[-1; n = 7); group III(PaO2 = 61.4 +/- 2.4 Torr; [Hb] = 13.3 +/- 0.4 g. 100 ml-1; n = 7). 2,3-DPG (group I : 1.05 +/- 0.06 mole.moleHb-1; group II : 1.02 +/- 0.08; group III : 1.11 +/- 0.08) was not significantly different of 2,3-DPG value of 12 control subjects (0.96 +/- 0.04). P50 of group I (26.9 +/- 0.9 Torr) and group III patients (28.1 +/- 1.6 Torr) was not significantly different of control value of P50 (27.4 +/- 0.5 Torr). P50 of group II patients (29.6 +/- 0.8 Torr) was significantly higher than P50 control and group I values (p less than 0.05). All the patients of group II died. These results suggest that in patients with chronic obstructive lung disease : 1) P50 value is different with various clinical conditions; 2) P50 increase is a compensatory mechanism in severe hypoxemia with anemia, but is not sufficient; 3) [Hb] is the best data for clinical prognosis.

[Respiratory function tests in epidermoid cancers of the bronchi].

The results of functional tests are analyzed in 50 cases of epidermoid bronchial cancers. Severe disorders take place in almost every patient. In one patient out of two, there is an old distension already existing prior to the cancer; in other patients gas exchange disorders can be improved by the intervention. Moreover, from some results a spreading of cancer towards the mediastinum is to be feared.
