[A retrospective study of carcinomas of the oral cavity: a preliminary report (author's transl)].

UNLABELLED: The German-Austrian-Swiss Research Team on Maxillofacial Tumours is investigating a series of 585 carcinomas of the oral cavity, lips and oropharynx by biostatistical methods. The aim of the study is the determination of relevant prognostic symptoms of oral cavity carcinomas, classification of the series on the basis of these symptoms, the determination of therapeutic efficacy and the assessment of collective and individual prognosis. PRELIMINARY RESULTS: 1. Factors of prognostic relevance are probably only tumour size and intensity of regional metastases. 2. The classification of the series becomes problematic due to the lack of relevant prognostic factors.

Carcinoma of the oral cavity: on the prognostic significance of the primary tumour site (by organs) in the oral cavity.

The prognostic significance of so-called organ sites was investigated in 585 cases with carcinoma of the oral cavity and lips. For the subsamples studied the numerical distribution of TNM categories, life tables and life table comparisons were computed. This produced the following results: 1. There is no demonstrable difference in prognosis between identical T catagories in the organs of the oral cavity. 2. In some cases there is a significant difference between identical N categories in organs of the oral cavity. In the No category this is, however, attributable to the substantial differences in the numerical distribution of T categories. By contrast, a logical explanation for the computationally demonstrable significant differences in the Nx category is not available. The problem is currently being investigated. 3. An assessment of identical TN combinations in the "organs" of the oral cavity proved to be impossible on account of the inadequate number of cases available. The so-called "organ localization" of primary tumours in the oral cavity need not - at least for the time being - be accorded any prognostic relevance. The findings should, however, be re-examined on the basis of greater numbers.

[Effect on carbohydrate metabolism of a new saluretic, etozolin].

The influence of Etozolin (Elkapin) on the carbohydrate metabolism was studied in 10 healthy volunteers, 6 patients with chemical diabetes and 10 with overt diabetes by blood glucose measurements and oral glucose tolerance tests with determinations of serum insulin levels. The healthy volunteers received 800 mg Etozolin per day during the treatment period of 3 days, the two groups of patients 400 mg Etozolin for 8 days. The laboratory parameters of the treatment period were compared with the corresponding values of the pre- and posttreatment periods and evaluated statistically. There was no statistically significant difference in the carbohydrate metabolism between the 3 test periods in all groups studied. As a result of the induced diuresis body weight, serum electrolytes and urine volume changed significantly during the Etozolin treatment as compared with the pre- and posttreatment values. Other changes of laboratory parameters could not be seen. In diabetic hypertensive patients a significant reduction of blood pressure was observed.

[Intracutaneous desensitization in a case of insulin allergy with anaphylactic shock (author's transl)].

In a 72-year-old woman with keto-acidaemia due to out-of-control diabetes, anaphylactic reaction occurred immediately after intravenous administration of 8 units of insulin. Extensive intracutaneous testing with highly purified insulins, including sheep and human insulin, revealed an allergy of the immediate type against the insulin molecule itself. Desensitization with subcutaneous insulin administration failed. Intracutaneous insulin injection three hours apart, starting at a dilution of 1:100, produced good subcutaneous tolerance of insulin within seven days.

[Epidemiology of peripheral vascular disease in diabetics (author's transl)].

623 non-selected diabetic outpatients were screened by the Doppler-ultrasonic-method for peripheral vascular disease. Additional angiologic work up was performed to define the location of stenosis and obliteration. 15.9% of the diabetics were shown to have peripheral vascular disease and 57% of those denied claudication. 9% of the patients had signs of mediasclerosis. The predilection of peripheral vascular disease in diabetics for the arteries below the knee (peripheral type) was confirmed in our study. Patients with a pelvic or femoropopliteal type of peripheral vascular disease showed a high frequency of cardiovascular risk factors. An influence of the duration of diabetes on peripheral vascular disease was not evident. In contrast to this, a significant correlation (p less than 0.001) of the peripheral type of peripheral vascular disease-as well as of mediasclerosis--could be demonstrated with the diabetes of long duration. In patients with the peripheral type of peripheral vascular disease significantly more often higher blood sugar volues were found. Thus the quality of metabolic control seems to be of some importance for this form of diabetic macroangiopathy.
