Atypical leukaemia of long duration with monoclonal hypergammaglobulinaemia.

A patient with atypical acute leukaemia is described. This patient has, in addition, monoclonal IgG hyperglobulinaemia without myelomatous lesions and is living and well three years after diagnosis. The cell types found in the blood and in the bone marrow are atypical, and the histochemical findings are discussed. The relationship between monoclonal hypergammaglobulinaemia and malignant blood diseases is also discussed, and the literature on the subject reviewed.

Lymph node enlargement after a single massive infusion of iron dextran.

Painful lymphadenopathy developed in eight female patients after massive infusions of iron dextran for sideropaenic anaemia. Fever, arthralgias, and malaise were also features of the clinical picture. The histology of one lymph node is described and changes in it are discussed in relation to the pathogenesis of the syndrome reported.

Serological markers of hepatitis B virus and hepatitis D virus infections in Greek adults with primary hepatocellular carcinoma.

Primary hepatocellular carcinoma (PHC) has been linked etiologically to chronic hepatitis B virus (HBV) infection by epidemiologic and molecular lines of evidence. Serologic evidence of HBV and hepatitis delta virus (HDV) infection was assessed in sera from 47 Greek patients with PHC. Radioimmunoassays for the detection of serological markers of HBV and HDV infections and molecular hybridization techniques for the detection of HBV DNA sequences were used. Serological evidence of HBV infection was found in 93.6% of PHC patients. Of the 47 patients, 20 (42.6%) were positive for HBsAg, 43 (91.5%) were positive for anti-HBc and 21 (44.7%) were positive for anti-HBs. Anti-HBe was detected in a high percentage (90%) of HBsAg positive PHC patients. Anti-HBc IgM was also detected in 90% of HBsAg positive PHC patients; in contrast, HBV DNA was detected only in 5% of them. None of the 47 patients had serological evidence of HDV infection. These data show that HBV appears to be the principal etiological agent of PHC in Greece.

Computerized diagnosis of gastrointestinal helminths of humans.

An interactive computer program written in BASIC with the objective of assisting the identification of species of common gastrointestinal parasites of humans is presented. The computer program acquires observational information needed for the identification of a parasite from the user. The user selects a description from a set of given descriptions that best fits the parasite observed. Depending on the response of the user, the program presents another set of descriptions from which the user must choose again, and so on, until the program concludes with the species of the parasite, the mode of infection, the affected system(s), and the treatment of choice.

The effect of dietary protein levels before turnout on subsequent faecal nematode egg output of grazing sheep in the Joannina region of Greece.

The effect of dietary protein levels before turnout on the subsequent faecal egg output of gastrointestinal nematodes was examined in two genotypes of grazing sheep, with or without anthelmintic treatment. Lambs were given a low protein (LP) or a high protein (HP) diet for three months (December to March) until grazing started. Half of the animals in each diet group were given anthelmintic treatment (AT) in March and June. The four groups (LP-AT, LP-NT, HP-AT and HP-NT) each consisted of pure-bred Butsiko and cross-bred Butsiko/Karamaniko lambs and grazed separate plots that were initially parasitologically and nutritionally similar. Faecal egg counts were recorded monthly until the experiment ended in July. Mean faecal counts for strongyle-type eggs were higher in the LP-NT group than all the other groups and higher in the LP than the HP groups indicating that faecal egg counts during grazing were influenced by levels of dietary protein before turnout. This effect was intensified in the absence of anthelmintic treatment. No genotype differences were detected.

Serum protein markers (Hp, GC, C3) in patients with colon cancer.

The phenotypes and gene frequencies of three serum protein systems--Hp, GC and C3--were studied in 184 consecutive patients from all over Greece with colon cancer. Healthy Greeks studied previously in our department served as controls. No significant differences were found between patients and controls concerning GC and C3. Significant differences were found in the Hp system; the frequencies of the Hp*1 gene and the Hp 1-1 phenotype were significantly higher in patients than in controls.
