PANEL DISCUSSION ON DIABETES MELLITUS IN THE AGED

MODERATOR KINSELL: The problem of diabetes is with us constantly, whether we are interested in pediatrics, geriatrics, or just people. Diabetes lends itself to a group approach. The disease affects so many organs and systems that the opinions and experience of many men are necessary in order to see the problem in its entirety and to approach it constructively. The panelists have extensive backgrounds, interest, and experience in this disease. They will speak on certain aspects of it and then will discuss points of agreement and disagreement in terms of a general plan of organization. The third phase of the discussion will be devoted to the consideration of specific questions from the audience. Dr. Root, will you begin todays discussion of diabetes in the aged with a presentation of the over-all problem? DR. ROOT: Diabetes in persons 60, 70 and 80 years of age has become an increasingly important problem in hospital populations and in office practice as well. The problem is numerically greater than ever before. Also, it is practically important in terms of treatment, diet regulation, and the management of complications. In surgical complications such as fractures, there are the problems of

Effect of hypophysectomy on pigmentation and ascorbic acid excretion in black rats.

Summary Pigmentation was observed in black rats following hypophysectomy, similar to the pigmentation occurring in black rats following adrenalectomy. The adrenals of the hypophysectomized rats were smaller than normal, with atrophic cortices. Excretion of ascorbic acid decreased to low levels following hypophysectomy. The increase in pigmentation is believed to be related to the derangement of the steroid hormones of the adrenal cortex of the hypophysectomized rat.

Lack of Effect of Sodium Phenosulfazole (Darvisul) on Certain Experimental Virus Infections.

Summary Under the circumstances which have been described, Darvisul revealed neither prophylactic nor therapeutic value in mice infected with the MM virus, the Lansing strain of poliomyelitis virus or Theilers virus of mouse encephalomyelitis (TO).

Acid-fast membranes of lipid pneumonia by fluorescence microscopy.

Summary Fluorescence microscopy using carbol-auramin or carbol-thioflavine which are spcific for acid-fast materials is recommended for the study of the membranes formed in lipid pneumonia where unsaturated lipids are suspected and for other familiar lipo-protein combinations, as more sensitive than the brightfield microscopy with Ziehl-Neelsen staining.
