[Course of superficial malignant tumors of the bladder. Apropos of 135 cases].

After recalling the difficulty of comparing the various series published in the literature. in the absence of common histological criteria. the authors review the records of patients with a class III or IV carcinoma of the bladder. strictly confined to the musoca, whether or not the basal membrane was damaged (stage O or A), with the exclusion of all cases with histological invasion of the muscularis and any other clinical or radiological signs of deep infiltration: 135 records with a follow-up of at least 6 months. This study led to the following findings: - One third of the tumours progressed to deep infiltration and/or metastases. - This unfavourable course occurred. in almost 3/4 of cases. during the 2 years following the clinical presentation of the tumour. - Such a grave course may develop for tumours not affecting the basal membrane without it having always been possible to define the stage of infiltration of the chorion. - A metastasis may develop while the tumour remains superificial. - 5 out of these 135 patients developed 2 or more extra-urological carcinomas. - Two thirds of these superifical tumours did not invade the muscularis during the period of observation which in 41 cases exceeded 6 years. - The difficulty lies in detecting which superificial malignant tumours of the bladder will not recur. which will recur superficially (where preservation of the bladder is automatic) and which will recur with infiltration and/or metastases. where an aggressive therapeutic attitude should be adopted before any infiltration or diffusion of the tumour manifests itself. - Tumours which did not recur were unifocal. - All multifocal tumours treated conservatively recurred.

Radio-pathological correlation of occult tumor of the breast.

Small tumors of the breast, both benign and malignant, may remain clinically silent for some time before they become large enough to be palpable. In many cases the tumor is revealed on a mammogram that is performed only as part of a routine check-up. The spectrum of radiographic appearances of these "occult" tumors is described and correlated with histological findings. In a significant number of cases there is an overlap in mammographic appearance of these nonpalpable benign and malignant lesions and a biopsy is necessary. The techniques of spot localization are discussed, and the importance of this procedure prior to biopsy is stressed as an aid to the surgeon in localizing the abnormality. Results of studies and attempting to analyze and classify high risk radiographic patterns are reviewed. Reduction in mortality lies in detection of breast cancer in as early a stage as possible.

[Sleep and dreams in patients with parietal and frontal lobe lesions].

Polygraphic recordings, psychological tests, and analyses of dreams during paradoxical sleep were conducted in 9 patients with parietal lobe, in 7 with frontal lobe lesions and in a control group. No significant differences in sleep organization were observed in the parietal group, but there was a considerable reduction in oneiric activity and alterations in results of some psychological tests. Several correlations based on statistical data are discussed. Oneiric activity was disorganized to a much lesser degree in patients with frontal lesions.
