The milk and the honey: ethics of artificial nutrition and hydration of the elderly on the other side of Europe.

Many health problems that elderly people face today relate not only to the nature of their affliction but also to the kind of treatment required. Such treatment often includes artificial nutrition and hydration, (ANH) a procedure which, despite its technical and invasive character, is still considered to be vested with symbolic meanings. It is precisely during the efforts to reach a legal consensus that the discrepancies between various cultural contexts become obvious. The following case explores the Greek clinical territory in comparison with the international situation, and the reasons why, in Greece, the right to refuse treatment is not necessarily interpreted as including the right to refuse artificial nutrition and hydration as well.

Plasma lipoprotein pattern in relation to liver histology after toxic hepatitis and experimental biliary obstruction in rabbits.

Plasma lipoproteins were studied in relation to liver histology in rabbits in the course of toxic hepatitis and compared to those after experimental biliary obstruction. The lipoprotein electrophoretic pattern became deeply abnormal during the acute phase of toxic hepatitis and correlated with the degree of liver injury, improving during recovery. Liver damage was more severe after carbon tetrachloride than after alcohol and milder after allylo-isopropyl-acetamide, a porphyrinogenic substance. Lipoprotein abnormalities were not followed by significantly reduced levels of cholesterol esters in the plasma. In comparison, animals with biliary obstruction developed milder liver damage presented gross abnormalities of plasma lipids and lipoproteins, followed by relative deficiency of cholesterol esterification. It is concluded that lipoprotein changes in acute liver injury, although non-specific, are a sensitive index of liver damage and recovery. Serious acute liver injury can exist without significant fall in cholesterol esters.

Carcinoma on old frostbites.

Two cases of carcinoma developing on old frostbite scars of the heel are presented. A short review of the subject follows, stressing the rarity of these "secondary" tumors and their general context within the skin cancers and the tragic experience of Greece with frostbite in the campaign of 1940-1941.

HLA antigens in Greek patients with cholelithiasis.

The distribution of HLA-A and B antigens was studied in 100 patients with cholelithiasis and in 202 healthy individuals all of Greek origin. An increased frequency of HLA-Aw19 was found in patients (33 per cent) compared with controls (22 per cent) (p less than 0.05, RR 1.7). The increase of Aw19 was even higher for patients with a family history of the disease (44 per cent, vs 22 per cent, p less than 0.01, RR 2.7) and for patients with cholesterol gall stones (44 per cent vs 22 per cent, p less than 0.01, RR 2.5). No difference was seen in patients without a family history of disease or with mixed gall stones. These results suggest a genetic basis for the development of cholesterol gall stone disease.
