Brachial plexus involvement from carcinoma of the breast produces a severe disability which presents difficulties in diagnosis and treatment. Five patients who suffered this complication are described and the problems they present are discussed.
This paper is a retrospective analysis of 397 patients with glottic cancer, in which 240 patients were treated in air, and 157 patients in a hyperbaric oxygen chamber (HBO). The three principal dose/time schedules in air and HBO are contrasted, and shown to be iso-effective. The local tumour control rates show a significant improvement in favor of HBO: Stage I, 10%; Stage II, 37%; Stage III, 73%. Morbidity rates are explored, and suggest that the increased local control rate is not attained at the cost of an increased morbidity rate. The planning of the treatment, the preparation of the patient, and any subsequent complications are described. Treatment in the HBO chamber in a busy department has been shown to be a safe and routine procedure.

Posterior nasal space carcinoma has a high mortality and most patients are treated with radiotherapy. Radiation retinopathy was encountered in 7 out of 10 survivors included in this study. Five of the affected patients lost vision as a result of the retinopathy. One patient required laser photocoagulation and responded well to this treatment. There was a variation in the severity of the retinopathy among the patients studied despite the fact that all patients received a similar dose of radiotherapy. We suspect that previously unrecognised factors in the planning of radiotherapy fields may explain this difference.
Generalised glycogenosis was diagnosed in Brahman cattle on 4 Queensland properties on the basis of clinical observations and pathological and biochemical findings. The disease presented as a problem of ill-thrift and poor growth rate in calves which eventually showed nervous signs. Histologically there was vacuolation in the cells of the central nervous system, heart and muscular tissues. Biochemical assay of liver and blood mononuclear cells demonstrated a deficiency of alpha-glucosidase. Parents of affected calves had approximately half the alpha-glucosidase activity of that found in normal cattle.
