Effectiveness of prolonged use of continuous passive motion (CPM), as an adjunct to physiotherapy,after total knee arthroplasty

Background  

Adequate and intensive rehabilitation is an important requirement for successful total knee arthroplasty.     

The cost of hospital-related care of patients with psoriasis in Italy based on the AISP study

The objective of this study was to assess the cost of caring for patients with psoriasis in Italy according to the AISP study (Associazione Italiana Studi Psoriasi or Italian Association for Studies on Psoriasis), involving 104 university and hospital centres and 7992 patients in 1994. The mean yearly cost of care for a single patient was calculated at 905 Euros. Hospitalization accounted for more than four-fifths of the costs, therapy for about one-eighth (systemic therapies were the most expensive) and office visits and day hospitals for the remainder. In our study series less than 20% of patients accounted for more than 90% of the total costs.     

FAT ARMS,OBESITY AND CHOICE OF BLOOD PRESSURE CUFF SIZE IN DIABETIC PATIENTS

SUMMARY Four hundred consecutive diabetic patients had their mid-arm circumference (AC) measured and body mass index (BMI) calculated to determine the proportion of an unselected clinic group who would require a larger than standard adult blood pressure (BP) cuff and whether or not BMI could be used to predict AC and hence choice of appropriate BP cuff size. More than 75% of both men and women had an AC ≥29cm, justifying a larger than standard adult cuff for their BP measurement. When patients were classified according to their BMI, at least 80% with a BMI ≥30 and more than 70% with a BMI of 25-29 had a measured AC ≥29cm, while less than a third of patients with a BMI ≥25 had an AC ≥29cm. These results indicate that, in a diabetic clinic, most patients with a BMI ≥25 are likely to require an alternative adult BP cuff if their blood pressure is to be measured precisely.     

A cytokine receptor gene cluster in the X-Y pseudoautosomal region?

The receptors for interleukin-3 (IL-3), IL-5, and granulocyte- macrophage colony-stimulating factor (GM-CSF) are heterodimers comprised of ligand specific alpha chains and a common beta chain. The genes encoding the IL-5 receptor alpha chain and the common beta chain reside on chromosome 3 and 22 respectively, while the GM-CSF receptor alpha chain gene (CSF2RA) has been mapped to the pseudoautosomal region (PAR) of the sex chromosomes, which is a 2.6-Mb stretch of homologous sequence at the tips of the short arms within which a single obligatory recombination occurs during male meiosis. We have mapped the gene encoding the IL-3 receptor alpha chain (IL3RA) to the sex chromosomes by polymerase chain reaction (PCR) analysis of human-mouse or human- chinese hamster cell hybrids, and to Yp13.3 and Xp22.3 using fluorescence in situ hybridization. To explore the possibility that IL3RA is located within the pseudoautosomal region we screened the Centre d'Etude du Polymorphisme Humain (CEPH) pedigrees for an informative-restriction fragment-length polymorphism (RFLP) that showed male meiotic recombination. Two informative CEPH pedigrees were identified that displayed this phenomenon, confirming the psuedoautosomal location of IL3RA. Using long-range restriction mapping we have found that IL3RA maps to the same 190-kb restriction fragment as CSF2RA, suggesting that a cytokine receptor gene cluster may reside in the PAR.     

Procalcitonin (PCT) and C-reactive Protein (CRP) as severe systemic infection markers in febrile neutropenic adults

Background  

Procalcitonin (PCT) is an inflammatory marker that has been used as indicator of severe bacterial infection. We evaluated the concentrations of PCT as a marker for systemic infection compared to C-reactive protein (CRP) in patients neutropenic febrile.     

Identification of residues in the first and fourth helices of human granulocyte-macrophage colony-stimulating factor involved in biologic activity and in binding to the alpha- and beta-chains of its receptor

Residues within the first and fourth helices of human granulocyte- macrophage colony-stimulating factor (hGM-CSF) were analyzed for their role in biologic activity and interaction with the alpha- and beta- chains of the hGM-CSF receptor. Within the first helix substitution of the surface residues Glu14, Asn17, Gln20, Arg23, Arg24, and Asn27 or the buried residues Ala18, Leu25, and Leu28 did not significantly impair bioactivity or receptor binding. Substitutions at the buried residues Ala22 and Leu26 had intermediate bioactivity. However, substitutions of the surface residue Glu21 or the buried residue Ile19 reduced the relative bioactivity of the analogues to as little as 0.45% and 0.3%, respectively. Substitution of the charged surface residues of the fourth helix showed that substitution at Glu104, Lys107, and Lys111 had no significant effect on bioactivity, but substitution at Glu108 and Asp112 reduced the potency of the analogues to 34% and 7%, respectively. Receptor binding studies showed that, whereas Glu21 is the critical residue for binding to the hGM-CSF-receptor beta-chain, Asp112 is likely to be involved in binding to the GM-CSF-receptor alpha- chain. These results establish the relative contribution of residues in the first and fourth helices for GM-CSF bioactivity and receptor binding, and support a model where the fourth helix of GM-CSF interacts with the alpha-chain, and the first helix with the beta-chain of the GM- CSF receptor.
