[Time to limit the use of antibiotics in rosacea!].

Rosacea is a chronic inflammatory disease with facial erythema and papulopustules. It is common in middle-aged/elderly persons and often affects self-perception and social well-being. It is generally classified into four subtypes.

Leaching of mercury-containing cement monoliths aged for one year.

A directive from the Swedish Government states that waste containing more than 1% of mercury shall be permanently deposited. The stabilization of mercury by conversion to a sparingly soluble compound like the sulphide is crucial to ensure long-term immobilization in a permanent storage. Immobilization by the solidification/stabilization (S/S) method and possible formation of HgS from mercury oxide or elemental mercury by reaction with a sulphur source (S or FeS) is investigated by a modified version of the NEN 7345 Dutch tank-leaching test.

Genome-wide association analysis identifies loci for type 2 diabetes and triglyceride levels.

New strategies for prevention and treatment of type 2 diabetes (T2D) require improved insight into disease etiology. We analyzed 386,731 common single-nucleotide polymorphisms (SNPs) in 1464 patients with T2D and 1467 matched controls, each characterized for measures of glucose metabolism, lipids, obesity, and blood pressure. With collaborators (FUSION and WTCCC/UKT2D), we identified and confirmed three loci associated with T2D-in a noncoding region near CDKN2A and CDKN2B, in an intron of IGF2BP2, and an intron of CDKAL1-and replicated associations near HHEX and in SLC30A8 found by a recent whole-genome association study.

Diffusion tests of mercury through concrete, bentonite-enhanced sand and sand.

The transport by diffusion of Hg(II) and Hg(0) through a barrier of concrete or bentonite-enhanced sand was examined under aerobic conditions. Sand was used as a reference system parallel to the two systems. Speciation of mercury was performed with a purge and trap method, where dissolved Hg(0) was purged with nitrogen gas from the sample, through a trap for volatile oxidized mercury species and finally trapped in an oxidative solution.

Formation of cinnabar--estimation of favourable conditions in a proposed Swedish repository.

A deep repository for permanent storage of mercury will be designed and built in Sweden. The preferred chemical state for mercury in such a repository would be the sulphide HgS (cinnabar), which is a highly insoluble and the dominating natural mercury mineral. The possible formation of HgS from HgO or Hg(0) by reaction with a sulphur source (S, FeS or FeS(2)) is discussed from thermodynamic considerations, and pe-pH-diagrams are constructed by using the computer code MEDUSA to illustrate under which conditions HgS would dominate.

Influence of childhood atopic dermatitis on future worklife.

Objectives: The purpose of this study was to perform a population-based follow-up of people with childhood atopic dermatitis with respect to the possible influence on their worklife.

Methods: Medical records of the school health care services in Stockholm, Sweden, were reviewed for people born between 1960 and 1969. Altogether 600 persons with signs of atopic dermatitis ("cases") and 600 matched controls without eczema ("controls") were identified.

Different IgE reactivity profiles in birch pollen-sensitive patients from six European populations revealed by recombinant allergens: an imprint of local sensitization.

Background: Sensitivity to birch pollen allergens is a common feature among European patients with seasonal pollen allergy. In this in vitro study, we examined the specific serum IgE binding profiles to individual birch pollen allergens in birch-sensitive patients from six European populations.

Methods: The study included 242 patients from Finland, Sweden, Austria, France, Switzerland and Italy.

Pharmacodynamic effects of nitroimidazoles alone and in combination with clarithromycin on Helicobacter pylori.

Pharmacodynamic studies of Helicobacter pylori exposed to metronidazole and tinidazole alone and in combination with clarithromycin were performed by bioluminescence assay of intracellular ATP. The pharmacodynamic parameter control-related effective regrowth time (CERT) was used. CERT is defined as the time required for the resumption of logarithmic growth and a return of the level of growth to the preexposure inoculum in the test culture minus the corresponding time in the control culture.
