International periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis syndrome cohort: description of distinct phenotypes in 301 patients.

OBJECTIVES: The aims of this study were to describe the clinical features of periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis (PFAPA) and identify distinct phenotypes in a large cohort of patients from different countries. METHODS: We established a web-based multicentre cohort through an international collaboration within the periodic fevers working party of the Pediatric Rheumatology European Society (PReS). The inclusion criterion was a diagnosis of PFAPA given by an experienced paediatric rheumatologist participating in an international working group on periodic fever syndromes. RESULTS: Of the 301 patients included from the 15 centres, 271 had pharyngitis, 236 cervical adenitis, 171 oral aphthosis and 132 with all three clinical features. A total of 228 patients presented with additional symptoms (131 gastrointestinal symptoms, 86 arthralgias and/or myalgias, 36 skin rashes, 8 neurological symptoms). Thirty-one patients had disease onset after 5 years and they reported more additional symptoms. A positive family history for recurrent fever or recurrent tonsillitis was found in 81 patients (26.9%). Genetic testing for monogenic periodic fever syndromes was performed on 111 patients, who reported fewer occurrences of oral aphthosis or additional symptoms. Twenty-four patients reported symptoms (oral aphthosis and malaise) outside the flares. The CRP was >50 mg/l in the majority (131/190) of the patients tested during the fever. CONCLUSION: We describe the largest cohort of PFAPA patients presented so far. We confirm that PFAPA may present with varied clinical manifestations and we show the limitations of the commonly used diagnostic criteria. Based on detailed analysis of this cohort, a consensus definition of PFAPA with better-defined criteria should be proposed.

Towards and ab initio description of magnetism in ionic solids

The physical contributions to the KNiF3 magnetic exchange coupling integral have been obtained from specially designed ab initio cluster model calculations. Three important mechanisms have been identified. These are the delocalization of the magnetic orbitals into the anion p band, the variational contribution of the second-order interactions, and the many-body terms hidden in the two-body operator and the Heisenberg Hamiltonian.

Age differences in biological monitoring of chemical exposure: a tentative description using a toxicokinetic model

AIM: Specific factors responsible for interindividual variability should be identified and their contribution quantified to improve the usefulness of biological monitoring. Among others, age is an easily identifiable determinant, which could play an important impact on biological variability. MATERIALS AND METHODS: A compartmental toxicokinetic model developed in previous studies for a series of metallic and organic compounds was applied to the description of age differences. Young male physiological and metabolic parameters, based on Reference Man information, were taken from preceding studies and were modified to take into account age based on available information about age differences. RESULTS: Numerical simulation using the kinetic model with the modified parameters indicates in some cases important differences due to age. The expected changes are mostly of the order of 10-20%, but differences up to 50% were observed in some cases. CONCLUSION: These differences appear to depend on the chemical and on the biological entity considered. Further work should be done to improve our estimates of these parameters, by considering for example uncertainty and variability in these parameters. [Authors]

Policy -Strategy Option Description, January 30, 2009

Like many states, Iowa faces significant challenges on the energy front.  Energy prices have  surged in recent years to record levels before declining precipitously following the financial  crisis that broke in September 2008.  Despite this pullback, the fundamentals that contributed to  higher energy prices are expected to return once economies rebound. Oil prices have gone up  on increased demand, driven in large part by developing countries such as China and India,  whose economies have been rapidly expanding.  Natural gas prices have also fluctuated  dramatically, trading in a range from $4.50 to $13.00/MMBtu over the past year, but are unlikely  to remain at low levels over the long term.  As shown in our analysis later on in this report, the  difference in levelized cost of electricity from a gas‐fired combined cycle plant can vary  significantly depending on the fuel cost.    Dependence on others for energy supply involves significant risks and uncertainties.  Thus, if  Iowa wishes to reduce its dependence on others – or even achieve energy independence – Iowa  needs to pursue actions on a numbers of fronts.  Following the status quo is not an option.    A carbon tax would change the energy landscape in Iowa.  Since Iowa is currently 75%  dependent on coal, a carbon tax could mean that generators, and in turn ratepayers, could be on  the hook for higher electricity prices, though it remains to be seen exactly what the tax scheme  will be.  In addition to existing plants, a carbon tax would also have a significant impact on the  cost of new generation plant.  We have modeled carbon taxes ranging from $0‐50/ton in our  analysis in the Appendix.  However, if a more aggressive carbon policy came into play resulting  in market values of for example, $100/ton or even $200/ton, then that could raise the cost of coal‐  and gas‐fired generation significantly, making alternatives such as wind more economical.
