Risk of malignant lymphoma following viral hepatitis infection.

We investigated lymphoma risk following hepatitis infection in a case-control study of 274 incident lymphoma cases, defined according to the WHO classification, and 336 population controls in Sardinia, Italy. Part of our study population (198 cases and 219 controls) was included in the EPILYMPH study of Hepatitis C virus (HCV) infection in relation to non-Hodgklin's lymphoma risk. Based on questionnaire information on whether and at what age a diagnosis of hepatitis was posed by a physician, systematic anti-HCV antibodies testing in cases and controls by enzyme-linked immunoassay, and HCV-RNA assessment by PCR analyses in positive samples, we investigated more in detail whether hepatitis non-C is also associated with lymphoma risk, and whether risk varies by clinical form of hepatitis (acute or chronic infection).

Glucose-6-phosphate dehydrogenase polymorphism and lymphoma risk.

Aims And Background: Evidence linking the glucose-6-phosphate dehydrogenase (G6PD) polymorphism and risk of non-Hodgkin's lymphoma is conflicting. Risk of non-Hodgkin's lymphoma was increased in subjects expressing the G6PD deficient phenotype, whereas subjects under medication with statins, a lipid-lowering class of drugs partially mimicking G6PD deficiency, seemed to enjoy a protective effect.

Methods: We conducted a case-control study on lymphoma risk associated with the self-reported G6PD deficient phenotype in 122 lymphoma male cases and 116 male controls in Sardinia, Italy.

[Anti-HLA antibodies in nephropathic patients].

Background: The presence of anti-human leukocyte antigen (HLA) alloantibodies in nephropathic patients is due to immunogenic stimuli such as transfusions, pregnancies, and transplantations. These stimuli can be highlighted using a classic aspecific serologic technique, such as complement-dependent cytotoxicity (CDC) or using more recent and specific techniques, such as cytofluorimetrics or enzyme linked immunoabsorbant assay (ELISA). Because the presence of anti-HLA preformed antibodies is linked to the largest incidence of both acute and chronic rejection, it seems appropriate to re-evaluate that data obtained using aspecific classic serological analysis techniques by using the more specific cytofluorimetric technique.

Mortality in a cohort of men expressing the glucose-6-phosphate dehydrogenase deficiency.

The objective of this study was to test the hypothesis of a lower mortality from cancer and cardiovascular diseases among men expressing glucose-6-phosphate dehydrogenase (G6PD) deficiency. We designed a mortality study based on death certificates from January 1, 1982 through December 31, 1992 in a cohort of G6PD-deficient men. Cohort members were 1,756 men, identified as expressing the G6PD-deficient phenotype during a 1981 population screening of the G6PD polymorphism.

Cerebro-costo-mandibular syndrome: early sonographic prenatal diagnosis.

In this case report the sonographic appearance of cerebro-costo-mandibular syndrome is described. Increased fetal nuchal translucency (at 11 weeks), micrognathia (at 12 weeks) and failure to ultrasound to identify the ribs (at 18 weeks) were revealed with serial scanning. These cardinal findings allowed the prenatal diagnosis of cerebro-costo-mandibular syndrome to be made at 18 weeks' gestation.

The enhancing effect of fasting/refeeding on the growth of nodules selectable by the resistant hepatocyte model in rat liver.

Caloric restriction causes a generalized decrease in growth rate and has been shown to delay the development of both spontaneous and induced neoplasia. In contrast to chronic food restriction, the extreme condition of fasting/refeeding is associated with an overall increase in cell turnover in several organs, including liver, compared with regular feeding. The present study was therefore designed to investigate the effect of complete food withdrawal followed by refeeding on the growth of hepatocyte nodules in initiated rat liver.

Chordoma of the cervical spine. Case report.

We present a case of chordoma of cervical spine with spinal cord compression at the level C4-C5-C6 in a woman of 65 years old. The diagnosis depends on the results of the histological studies and especially the studies of the labeled elements as protein S 100. For the operation was used an anterior approach and a somatectomy of the interested vertebrae.

Reproducibility of histologic classification of gastric cancer.

A panel review of histologic specimens was carried out as part of a multi-centre case-control study of gastric cancer (GC) and diet. Comparisons of diagnoses of 100 GCs by six pathologists revealed agreement in histologic classification for about 70-80% of the cancers. Concordance was somewhat higher when using the Lauren rather than the Ming or World Health Organization classification systems.
