Experimental conditions were identical with those of medical practice. Spectra speeds of several films and spectral emission of intensifying screens were built up. Speeds of screen-film combinations, as well as definitions, were measured. Results are available to range the different screens-film systems after their speed factor, at 40, 70 and 120 kV, with mention of definition of these systems. It so objectively appears that rare-earth intensifying screens make possible a decrease of X-ray exposure for patient under a factor 2 to 2,5 and a less early wearing of apparatus, namely of X-ray tubes.

The images obtained are similar to those observed in wuchereriasis. The microfilariae in onchocerciasis, however, are not transmitted in the lymphatic system, and the lesions, which vary according to the degree of infestation, show little progression. They are found mainly in the inguino-crural ganglia which are the first main ganglionic relay system for the lower limbs.

The malignant lymphomatous nature of the lesion could not be confirmed as a bone biopsy was not made, but its regression under chemotherapy makes the diagnosis almost certain. Indirectly, arguments in favour of this hypothesis can be drawn from the common cellular origin of bone lymphomas and monoclonal gammopathies. Furthermore, it is logical to assume that heavy chain alpha disease, as with most other immuno-proliferative syndromes, can be associated with malignant lymphomatous changes in the skeleton.

Two of them (severe post-operative bleeding and following needle-biopsy of the liver) were completely cured by highly selective arterial embolus production. No definite diagnosis was established in the third case (liver angioma with large artero-portal fistula). It can be seen from these observations, that angiography is essential in patients with bleeding into the bile ducts. The reason is not to establish the diagnosis but to find the precise location of the lesion and, under certain conditions, to apply radical treatment by highly selective arterial embolus production.

This method enables the corticomedullary junction to be visualized in the nephrography, which is an important point in differential diagnosis. An analysis is made of the results obtained from early nephrotomographies in 50 patients with acute or chronic renal insufficiency. Satisfactory nephrographies were obtained in all cases and the position and size of the kidneys could be established. Certain nephrotomographic abnormalities appear more frequently during the course of some types of chronic nephropathies, and this can assist aetiological classification. The existence of dilated secretory cavities in the superior part of the kidney can be established very quickly. In this way it is possible to differentiate clearly between parenchymatous nephropathies and those due to obstruction, such as when oliguria or anuria is present. The presence of a persistent homogenous nephrography would evoke, under these same conditions, an acute medical nephropathy.

The fingers were of adult length and wider. Arteriography did not show any evidence of an aneurism but demonstrated the existence of an extensive collateral circulation. Thermography confirmed the hypervascularization with the presence of hot points. The authors found reports on 118 cases in the literature published during the last century which could be analyzed statistically. There is a slight predominance in boys (55%) and on the right side. Two fingers are usually involved, the index and middle finger being those affected. Discussions as to aetiology (GOURNET) usually vary between a neurological cause with the possibility of a fibrolipoma of the middle finger being present, and it being due to a phacomatosis. Effective therapy in adults is amputation. In the young there are several possibilities; ablation of the neurovascular masses at the base of the fingers (even though the metacarpals are often involved), destruction of proliferating cartilage, etc.

In 3 cases these lesions were more advanced than the sacro-iliac alterations which were very slight or even doubtful. In 8 patients with severe Reiter's disease, 7 developed an ankylosing spondylitis and 2 presented involvement of the manubrio-sternal joint 8 weeks, respectively 10 weeks after the appearance of the first symptoms.

Cicatricial digitiform pseudopolyposis is a rare condition. We have found reports on only 12 cases in the literature from 1952. Recently, ten cases in 190 patients with Crohn's disease have also been reported. This particular type of pseudopolyposis appears in two different forms: diffuse or localized ("giant"). Diagnosis can be difficult if there is no history of colitis which is nearly always from hemorrhagic rectocolitis or Crohn's disease. The diffuse form can be confused with polyposis of the colon from any cause, while the localized "giant" form can evoke a tumour especially of the villous type. An essential diagnostic procedure is the anatomical and pathological examination of the polypoid mass by surgical biopsy. Cicatricial pseudopolyposis does not require surgical intervention except when rare complications such as invagination caused by the pseudopolypoid mass occurs. Radiologists should bear in mind this particular form of pseudopolyposis, as correct identification can avoid unjustified surgical intervention.

A total of 10,600 diagnostic examinations were reviewed and 5 perforations were recorded, to which must be added 2 perforations following oesophageal dilatation. A chesy X-ray, taken within 24 hours of the incident, showed, in most cases, the presence of air in the mediastinum with early signs of subcutaneous emphysema in the cervical or cervicothoracic regions. A hydro-pneumothorax in the right side of the chest was also observed in the cases studied, without air in the mediastinum. Oesophageal transit was studied by means of a water-soluble compound, and showed oesophageal effraction in only 4 cases, and in 3 of these cases it was possible to see the location of the orifice with precision.

The distal arterial segment was revascularized by two homolateral ureteral arteries. A full review of the literature revealed 30 cases of renal artery lesions for which angiography had been carried out in young people with neurofibromatosis. This demonstrates the low incidence of obliterative lesions (4 cases throughout the world) which are always associated with collateral vascularization. It was not possible to apply the usual surgical treatment in our case because of the associated horseshoe kidney.
