Two patients with lateral subluxation of the atlas resulting from rheumatoid disease involving the upper cervical spine have been described. The deformity can be suspected on clinical grounds and in one of our two patients spinal cord damage was a sequel. Erosion of the opposing surfaces of the odontoid and lateral masses of the atlas with detachment of the transverse ligament and deeper fibres of the posterior longitudinal ligament appear to underlie this deformity. Radiological confirmation may require AP views with the head tilted to one or other side.

Clinical Trial
Hyperbaric oxygen: the Medical Research Council trials and their clinical significance.
The clinical trials of the use of hyperbaric oxygen in radiotherapy conducted by the Medical Research Council's working party have shown that local cure and survival can be improved in head and neck and cervical cancer. Evidence for benefit has been presented in carcinoma of bronchus, but none has so far been found in carcinoma of the bladder. ⋯ The future use of hyperbaric oxygen in radiotherapy will depend upon a comparison of effectiveness with other methods now being tested to improve radiotherapy. The trials have yielded much fundamental and clinical data of general relevance in the radiotherapy of malignant disease.

Randomized Controlled Trial Clinical Trial
Hyperbaric oxygen and radiotherapy: a Medical Research Council trial in carcinoma of the cervix.
In a randomized controlled clinical trial of hyperbaric oxygen in the radiotherapy of advanced carcinoma of the uterine cervix a total of 320 cases were contributed by four radiotherapy centres in the United Kingdom. The use of hyperbaric oxygen resulted in improved local control and survival. The benefit was greatest in patients under the age of 55 who presented with stage III disease. There was a slight increase in radiation morbidity but it seemed that the benefit of hyperbaric oxygen outweighed this increase in morbidity and that there was a true improvement in the therapeutic ratio.
