Summary Background. Volumetric pollen traps are commonly used to assess pollen exposure. These traps are well suited for estimating the regional mean airborne pollen concentration but are likely not to provide an accurate index of personal exposure. In this study, we tested the hypothesis that hair sampling may provide different pollen counts from those from pollen traps, especially when the po...

In 1974, parvovirus B19 was discovered by co-incidence, and in 1983 found to be the etiology of erythema infectiosum. It is now generally accepted that parvovirus B19 epidemics occur approximately every three years in Denmark with sporadic cases occurring in between. There were no official recordings regarding parvovirus B19 epidemics in Denmark in 1991, but the fact that all pregnant women fro...

Disasters, war, and terrorism expose millions of children globally to mass trauma with increasing frequency and severity. The clinical impact of such exposure is influenced by a child's social ecology, which is understood in a risk and resilience framework. Research findings informed by developmental systems theory and the related core principles of contemporary developmental psychopathology ar...

" Even in cases of so-called beri-beri is the presence of the anchylostoma in them convincing evidence that they alone cause tbe disease and in the way suggested ? I think not."?Surg.-Major Dobson, Assam.?Report, 1892,^;. 66. " I altogether doubt the existence of any specific disease to which the term ankylostomiasis can be justly applied. * * * I maintain that it has yet to be shown that the p...

From the LEP precision data, upon excluding the observables Rb, Rc in a combined fit of the top-quark mass, mt, and the Higgs-boson mass, MH, within the Standard Model, we find the weak 1σ bound of 40GeV < ∼ MH < ∼ 1TeV. Stronger upper bounds on MH, sometimes presented in the literature, rely heavily on the inclusion of Rb in the data sample. Upon including Rb, the quality of the fit drasticall...

Survival from a malignant hyperthermia (MH) crisis is highly dependent on early recognition and prompt action. MH crises are very rare and an increasing use of total i.v. anaesthesia is likely to make it even rarer, leading to the potential risk of reduced awareness of MH. In addition, dantrolene, the cornerstone of successful MH treatment, is unavailable in large areas around the world thereby...
