Above acetabulum aneurismal cyst. One case (author's transl)]

One case of above acetabulum aneurismal cyst is presented and the authors insist on the main features of this benign tumor supplied with radiology, clinic and evolution. Location of such cyst are uncommon: 4 cases upon 137. Medical team has to resolve two problems: on one hand, positive diagnosis of this benign tumor, on the other hand, treatment of this particular location.     

Radiology of joint trauma (author's transl)]

Demonstration of the value of diagnostic radiology in the field of surgical trauma, especially in trauma of the skeletal system. Recommendation to place special emphasis on optimal X-ray technique - in the radiography of acute trauma as well as in follow-up studies.     

Unilateral oblique craniocaudal incidence of the sacro-iliac joint (author's transl)]

The author describes an oblique open-pelvis incidence, centered on the sacro-iliac of one side, carried out to study the anterior part of this joint. This incidence, which can be made on both sides for comparative purposes, easily complements standard sacro-iliac incidences.     

Pelvimetry (author's transl)]

A simple and precise technique for pelvimetry, delivering only a low dose of irradiation, is described. It includes the usual lateral view, but for the AP uses that of Fernstro?m. The technique and results are described.     

Delayed rupture of a metastatic-spleen following coeliacography (author's transl)]

A 49-year-old female patient died 7 days after coeliacography due to delayed rupture of the spleen. Apparently banal events are able to cause rupture of the spleen if metastatic or other pathological alterations are present. There is a brief discussion whether or not coeliacography could induce rupture of the spleen.     

Selective tomography in the study of the temporo-mandibular joint. (author's transl)]

The majority of temporo-mandibular pains and dysfunction can be related directly or indirectly to the occlusal relationship of the teeth. The first manifestation is a slight reduction of the interarticular space, that must be early diagnosed, to prevent organic changes. Tomography is the one technique able to give a exact information of temporo-mandibular joint. But if we ask to that examination to detect very slight change of the interarticular space, the technique must be accurate and established in function of morphology of the patient; we have observed great variations in direction of the axis of condyles from one person to the other, and even from one side to the other for the same subject. So that, the first stage of the roentgen examination will be a radiograph taken in submentovertical (Hirtz) position. We measure the angle formed by the axis of each condyle and the sagittal median plane. The maim beam wil be directed in the axis of the condyle for sagittal tomography and perpendicularly for frontal tomography. It is important to state precisely that for tomography "closed mouth", the patient must be in terminal occlusion during the whole examination. For tomography "open mouth" we place a wedge between dental arches.     

Chemotherapy in solid transplantation tumors following synchronization (author's transl)]

In order to examine whether the effects due to cytostatics might be improved by synchronization, cytosin-arabinoside, hydroxyurea or Vincristin were administered to rats bearing solid transplantation tumors, at different intervals following synchronization. The three substances, interfering with the S-phase of the cells, show significantly improved therapeutic results with quickly proliferating Walker-carcinosarcoma after a synchronization by hydroxyurea. Cyclophosphamide on the other hand, being effective through several phases of the cell cycle, furnishes no evidence of any essential therapeutic result. Analogous therapeutic experimentation using slowly growing neurosarcomas yielded no better results after synchronization. The concept of synchronization treatment may be approved, therefore, with certain limitations: firstly, synchronization with hydroxyurea can be maintained for a short time only, and the cancerous cells pass throught the first phases of the cell cycle following synchronization for the most part together with normal cells; secondly, only tumors with an important growth fraction and only cytostatics that do not affect several phases of the cell cycle are appropriate for synchronization therapy.     

Ureteral diverticulosis (author's transl)]

We report here two new cases of ureteral diverticulosis. This condition is found usually in the man of the fifties who has most frequently an urinary tract infection or a prostatic adenoma. The roentgen findings are multiple out-poutchings of the lumbar ureter. Several factors are combined (constitutionnal, urinary tract infection, disordered ureteral-motility) to explain the creation of diverticules in the areas of weakness of ureteral wall, where penetrate the vessels.     

Lumbar discography (author's transl)]

Discography appears to be the only means to give radiological, strictly anatomical and clear visual data on the nucleus of a disc. It is a comparatively simple and technically easy technique as long as one has the right tools and personnel. While it is disagreeable for the patient, it is not dangerous if strict asepsis can be applied. Discography gives an uncomplicated and unequivocal interpretation with sufficiently precise discometric and sensory signs which enable us to identify the lesion reliably. Tolerance and harmlessness of the technique are by now established. The indications refer to disc pathology and are indispensable before any arthrodesis carried out for pain in the lumbar spine or spondylolisthesis. These indications are now being extended to all problems of reports or difficult diagnosis of vertebral pathology. Discography also has a special and essential place with sciatica, particularly when radiculography is negative.     

Whiplash injury (author's transl)]

The whiplash injury is the result of a collision from behind in the motorized street traffic. The impact in the rear of the vehicle causes a sudden thrust to of the head and cervical spine in dorsal direction. The result is a shear effect of the cervical spine. Pathologically, this is characterized by hematoma of the capsules of the joints of the vertebral arches and contents of intervertebral foramina. Tears of discs and vertebral fractures are usually absent. The prognosis is good.     

Selective coronarography (author's transl)]

Advantages and disadvantages of coronographic techniques known so far are described. Disadvantages can be removed by the technique of premedication proposed by the authors which renders possible injection of contrast medium into the coronary vessels without reaction. The advantages of Theophyllin-premedication are described in detail. This technique is more reliable and provides better information in greater detail.     

Breast xeroradiography (author's transl)]

Breast xeroradiography is a new radiological technique based upon the electrostatic and not the photographic properties of silver bromide. We have used it particularly with reference to breast disorders in order to compare it to traditional procedures and to seek the best conditions to obtain the most informative picture by comparing the radiation emitted by a tungsten anode with the radiation emitted by a molybdenum anode with molybdenum or aluminium filtration. We concluded the xeroradiography was of value in breast problems in the following instances: 1. For certain types of microcalcification. 2. For the precise study of the relation of the breast to the chest wall. 3. For breast with a uniform high density on conventional films (young organ, fibro-glandular hyperplasia, after high-dosage irradiation). 4. In the study of deep seated carcinomas or those in the sub-mammary fold. 5. In studying the axilla where the ribs, muscles and nodes are seen together on the same film. Comparative study of xeroradiography using either a tungsten or molybdenum anode was markedly in favour of the latter under all the circumstances mentioned above.
