Cosmologically allowed regions for the axion decay constant
If the Peccei-Quinn symmetry is already broken during inflation, the decay
constant of the axion can be in a wide region from GeV to
GeV for the axion being the dominant dark matter. In this case,
however, the axion causes the serious cosmological problem, isocurvature
perturbation problem, which severely constrains the Hubble parameter during
inflation. The constraint is relaxed when Peccei-Quinn scalar field takes a
large value (Planck scale) during inflation. In this letter, we
point out that the allowed region of the decay constant is reduced to a
rather narrow region for a given tensor-to-scalar ratio when Peccei-Quinn
scalar field takes during inflation. For example, if the ratio
is determined as in future measurements, we can predict
GeV for domain wall number

Medium-size-vessel vasculitis
Medium-size-artery vasculitides do occur in childhood and manifest, in the main, as polyarteritis nodosa (PAN), cutaneous PAN and Kawasaki disease. Of these, PAN is the most serious, with high morbidity and not inconsequential mortality rates. New classification criteria for PAN have been validated that will have value in epidemiological studies and clinical trials. Renal involvement is common and recent therapeutic advances may result in improved treatment options. Cutaneous PAN is a milder disease characterised by periodic exacerbations and often associated with streptococcal infection. There is controversy as to whether this is a separate entity or part of the systemic PAN spectrum. Kawasaki disease is an acute self-limiting systemic vasculitis, the second commonest vasculitis in childhood and the commonest cause of childhood-acquired heart disease. Renal manifestations occur and include tubulointerstitial nephritis and renal failure. An infectious trigger and a genetic predisposition seem likely. Intravenous immunoglobulin (IV-Ig) and aspirin are effective therapeutically, but in resistant cases, either steroid or infliximab have a role. Greater understanding of the pathogenetic mechanisms involved in these three types of vasculitis and better long-term follow-up data will lead to improved therapy and prediction of prognosis
