Improving asthma treatment in a managed care population.

Objective: To identify and educate members of ConnectiCare, Inc & Affiliates, a regional managed care organization, who were not using asthma medications as recommended by the National Heart, Lung, and Blood Institute, by means of a nurse-administered 6-month telephonic case management intervention called the Asthma Treatment Awareness Project.

Study Design: A randomized controlled design was used to evaluate intervention and control groups. Self-selected members who opted in, opted out, or did not respond to an invitation to participate were included in the analysis.

LDLR, GYPA, HBGG, D7S8 and GC allele and genotype frequencies in the northwest Italian population.

Allele and genotype frequencies for five PCR-based DNA markers (LDLR, GYPA, HBGG, D7S8 and GC) were determined in 100 unrelated individuals from Piedmont (Northwest Italy). All five Ioci met Hardy-Weinberg expectations in the sampled population. The combined PD and CE were, respectively, 0.

Altered biosynthesis of tumour necrosis factor (TNF) alpha is involved in postburn hypertrophic scars.

The present study shows that the decrease of TNF alpha in postburn hypertrophic scars is due to a decrease in the steady-state level of TNF alpha mRNA and thus to an altered biosynthesis of the cytokine. Thirteen scars, including seven hypertrophic and six normotrophic scars, were tested for TNF alpha mRNA production by a semiquantitative reverse polymerase chain reaction (PCR) method. TNF beta and beta actin were tested as a control.

HLA supratypes in an Italian population.

A supratype analysis of a North Italian population was performed, using 16 polymorphisms in the HLA region spanning the HLA-A-DP segment. Fourteen supratypes were identified, mostly corresponding to those found in other Caucasoid populations. The degree of their conservation both within the B-DR/DQ region and in the regions telomeric and centromeric from HLA-A and DP was evaluated and linkage disequilibria among several DR and DP alleles were identified.

Quantitative expression of HLA class I molecules in acute non-lymphoblastic leukaemia cells.

The present study concerns a panel of 33 acute non lymphoblastic leukaemia (ANLL) patients, previously typed for HLA-A,B serological specificities and including samples with a normal HLA-A,B phenotype (3,4 detected specificities) as well as samples with missing and extra specificities. Samples were analysed at the protein and/or RNA level in order to verify whether the observed typing anomalies were due to a modified quantitative expression of class I molecules. The number of HLA-A,B assigned specificities correlated significantly with the cell surface class I expression detected by indirect immunofluorescence using the monomorphic anti-class I MoAb W6/32 (Spearman rank correlation test, P < 0.
