Bloom's syndrome (BS) is a rare autosomal recessive disease predisposing patients to all types of cancers affecting the general population. BS cells display a high level of genetic instability, ...including a 10-fold increase in the rate of sister chromatid exchanges, currently the only objective criterion for BS diagnosis. We have developed a method for screening the BLM gene for mutations based on direct genomic DNA sequencing. A questionnaire based on clinical information, cytogenetic features, and family history was addressed to physicians prescribing BS genetic screening, with the aim of confirming or guiding diagnosis. We report here four BLM gene mutations, three of which have not been described before. Three of the mutations are frameshift mutations, and the fourth is a nonsense mutation. All these mutations introduce a stop codon, and may therefore be considered to have deleterious biological effect. This approach should make it possible to identify new mutations and to correlate them with clinical information.
The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the Federation of french cancer centers (FNCLCC), the 20 French cancer centers, and specialists ...from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery.
To develop clinical practice guidelines for the use of medical analgesics for the treatment of pain arising from excess nociception in adults with cancer according to the definitions of the Standards, Options and Recommendations project.
In 1996, a working group, set up by the FNCLCC published clinical practice guidelines for pain management in adult and paediatric patients with cancer. In the light of the evolution of our knowledge, and practice these guidelines need to be updated. The section on "medical analgesic treatments" in the document published in 1996 was examined by the working group to identify which questions should be updated. These questions and the relevant key words were used to develop a search strategy which was used to search Medline , and for particular questions, Embase , from January 1994 to March 1999, for relevant references, published in English or French.
For this update, only a few randomised clinical trials were identified, and their conclusions were generally weak. Thus much of the information in this document is based on the World Health Organisation (WHO) guidelines and represents the "state of the art" on this subject in France and is supported by expert agreement. Some changes to the original SOR are presented, eg. methods of titration, prescription of new opioids, opioid rotation. We also present a synthesis of recent pharmacological and regulatory data. The integral version is available on the FNCLCC web site (http://www.fnclcc.fr/sor.htm).

To develop clinical practice guidelines for the use of opioid analgesics with the exception of oral morphine and for opioid rotation related to the treatment of nociceptive pain in adults with cancer according to the definitions of the Standards, Options and Recommendations project.

Serum-free culture of human monocytes in the presence of monoclonal antibodies to the LFA-1 alpha chain (CD11a), CR3 alpha chain (CD11b) or beta chain (CD18) bound to Sepharose induced the ...dose-dependent production of cell-associated interleukin (IL) 1 activity and of IL 1 alpha and IL 1 beta antigens, but no release of extracellular IL 1 activity or antigen in the culture medium. Triggering of IL 1 production was also observed with insolubilized anti-CD11/CD18 F(ab')2 antibodies. Two cross-linked antibodies recognizing distinct epitopes on the CD11b molecule induced cell-associated IL 1. Soluble antibodies did not induce IL 1 production. The kinetics of induction of IL 1 by stimulation of adhesion-promoting proteins differed from those of IL 1 induction by adhesion to plastic. The lack of induction of IL 1 release by stimulation of the CD11/CD18 molecules resembled the intracellular accumulation of IL 1 induced by lipid A. Induction of IL 1 by adhesive processes may be a mechanism by which T cells trigger IL 1 production by monocytes during antigen presentation.
