Benzodiazepine hypnotics bear a higher risk of high dose dependence than benzodiazepine anxiolytics, according to a recent study in Luxemburg. This article summarizes the main indications of these molecules and the current treatment recommendations. It provides an overview of public health actions of the past and the future to reduce their excessive consumption.

Hypnotics and Triazolobenzodiazepines--Best Predictors of High-Dose Benzodiazepine Use: Results from the Luxembourg National Health Insurance Registry.

Background: Benzodiazepines are not all the same concerning their risk of high-dose use.

Methods: We studied benzodiazepine use from the Luxembourg national records of all insured. We calculated the 12-year prevalence from 1995 to 2007.

Non-Hodgkin's lymphoma: time trends for incidence and survival in Côte-d'Or, France.

Background: A generally reported increased incidence of non-Hodgkin's lymphomas (NHL) and a recent evolution in treatment strategies, as well as several clinical trials suggesting improved survival, have prompted this study to evaluate time trends in incidence and prognosis of NHL.

Method: NHL recorded by the population-based Registry of Hematopoietic Malignancies in Côte-d'Or (France) were considered over three 4-year periods from 1980 to 1992. A multivariate survival analysis was carried out in terms of both crude and relative survivals.

Multiple primary cancers in the Vaud Cancer Registry, Switzerland, 1974-89.

Data collected by the Cancer Registry of the Swiss Canton of Vaud (whose population in 1980 was about 530,000 inhabitants) were used to estimate the incidence of second metachronous primary cancers following any specific neoplasm. Among 34,615 cases of incident neoplasms registered between 1974 and 1989 and followed through integrated active follow-up to the end of 1989, for a total of 118,241 person-years at risk, there were 2,185 second primaries (1,280 males, 905 females). For both sexes, the standardised incidence ratios (SIR) were significantly elevated by about 20%.

Linkage of death certification of AIDS and cancer registration in Vaud, Switzerland.

58 death certifications (40 males and 18 females) of residents of the Canton of Vaud (Switzerland) which reported AIDS as the cause of death in 1986-1989 were matched with the list of incident cancers available since 1974 from the Vaud Cancer Registry. Such linkage was successful for 20 individuals (age range 25-63, median 37), mostly males (18/20), homosexual or bisexual (11/18) and affected by Kaposi's sarcoma (14 males and 1 female). Other identified neoplasms included one Burkitt's lymphoma, one prostate adenocarcinoma and one multiple myeloma (whose histological picture included, however, lymphocytosis in addition to plasmocytosis).
