Cases* Controlst Total instead, available lists (cancer registers, admissions to hospital, notifications or registered deaths) are used, but then one cannot be sure that all cases have been assembled-for example a list of hospital admissions for ischaemic heart disease or for traumatic brain injuries would exclude deaths before' admission as well as mild episodes either not treated or treated b...

Nasopharyngeal carcinoma (NPC), the major cancer killer in Cantonese Chinese, represents one of the three cancer research priorities in China. Apart from some fundamental research projects on the Epstein-Barr virus (EBV), their main efforts are epidemiologically and clinically oriented. Major surveys in GuangDong and GuangXi provinces showed that high EBV/IgA/VCA serum levels can detect NPC at ...

Salivary cortisol measures are increasingly being incorporated into large-scale, population-based, or epidemiological research, in which participants are selected to be representative of particular communities or populations of interest, and sample sizes are in the order of hundreds to tens of thousands of participants. These approaches to studying salivary cortisol provide important advantages...

During 1998 I accompanied a cultural communication network in the production of epidemiological data, which used an ethnographic approach to studies of science. Inserted in the daily activities of an epidemiological research group, I registered some aspects of the scientific production process, such as the strategies and negotiations involved in the maintenance and circulation of the data produ...

in addressing health needs. The purpose of this text is to highlight some of the methodological challenges faced when conducting epidemiological research on epilepsy in resource-poor settings. An acute resource constraint is a dominant underlying feature of health services in developing countries. The treatment gap is huge (reaching more than 90%) in most places. As only a small fraction of PWE...

The recent identification of new biological markers (biomarkers) has created unprecedented opportunities for molecular or biochemical epidemiologists in cancer mesearch. Laboratory measurements used with traditional methods of epidemiology have undisputedly added a new dimension to studies of causal associations. Although the technological arm of molecular on biochernicab epidemiology has grown...

This paper takes as its starting point the assumption that the 'Epidemiological Imagination' has a central role to play in the future development of policies and practice to improve population health and reduce health inequalities within and between states but suggests that by neglecting the contribution that qualitative research can make epidemiology is failing to deliver this potential. The p...

The late effects of exposure to atomic bomb radiation on cancer occurrence have been evaluated by epidemiological studies on three cohorts: a cohort of atomic bomb survivors (Life Span Study; LSS), survivors exposed IN UTERO : , and children of atomic bomb survivors (F1). The risk of leukemia among the survivors increased remarkably in the early period after the bombings, especially among child...
