The lateral stooping radiograph has been utilized for many years in an attempt to demonstrate gastro-oesophageal reflux or hiatus herniae. The purpose of this paper is to describe our experience with this radiograph in evaluating other gastric lesions. It has proven particularly valuable in visualising the upper part of the stomach.

The authors present practical details on choice and preparation of radiology exhibits. The space requirements and materials available both in the exhibitor's department and in the exhibit hall are named, and suggestions are made for their most advantageous use. The exhibit should always be designed to stand alone, but it can at the same time be planned so as to supplement or reinforce ideas or concepts presented in a scientific paper.

Claims analysis and efficacy study are two new methods of evaluating medical services. In Manitoba, with a 1974 population of 1,053,382, approximately 100,000 patient-physician interfaces resulted in 16,594 barium enema examinations; 1,000 significant abnormalities were discovered, and the referring physician was unusually perceptive in predicting the likelihood of these abnormalities. It is estimated that a 10% reduction in the use of barium enemas could be achieved by referring physicians with no deterioration in the care of patients.

Anumber of roentgenographic manifestations of mongolism have already been described. Attention has been called to abnormalities of the cranial bones ((1, 3–5) and to characteristic features of the pelvis and hips (2). The purpose of this paper is to call attention to yet another finding, dislocation of the atlas, which appears to be significantly frequent in this disease. We recently observed such a dislocation in a ten-year-old mongoloid female who was referred to The University of Michigan Medical Center, Ann Arbor, Mich., because of accelerated skeletal maturation. The atlanto — odontoid distance measured 8 mm in the neutral position (Fig. 1). There were no symptoms or signs referable to the cervical spine and no history of trauma or other condition (8–10) which might explain this abnormality. It was therefore of interest to learn whether atlas dislocation was particularly common among mongoloid children. Method Cervical spine films of 18 mongoloids were obtained in neutral and flexion positions. Four ...

Atlas dislocation was observed in 14 of 70 mongoloid individuals of various ages. In addition, Scheuermann-like lesions, probably representing Schmorl's nodes, were present in young adults in the cervical and dorsolumbar segments of the spine. These were conspicuously absent in childhood. Possible pathogenetic factors are discussed.

Radiographs in 82 cases of severe frostbite injury seen at the Winnipeg General Hospital and Manitoba Rehabilitation Hospital from 1962 to 1970 were reviewed. Fifty per cent of these cases eventually demonstrated characteristic radiographic changes in the involved extremity, although no convincing bony changes were demonstrated on admission. Presence of subcutaneous gas was a bad prognostic sign. The involved limb in all such cases eventually required amputation.
