A prospective, population-based registration of children with immune thrombocytopenic purpura (ITP) was performed in Norway in 1996 and 1997. Ninety-two cases were identified, indicating an incidence of 5.3 per 100,000 children under 15 years. The sex ratio (female/male) was 1.2/1. Fifty-six percent presented with cutaneous signs only. The lowest platelet(More)
We investigated the relations among 83 hydrologic condition metrics (HCMs) and changes in algal, invertebrate, and fish communities in five metropolitan areas across the continental United States. We used a statistical approach that employed Spearman correlation and regression tree analysis to identify five HCMs that are strongly associated with observed(More)
A pleocytosis of the CSF occurred in all of 10 children with mumps meningitis and persisted for weeks and months in some patients. Oligoclonal IgG proteins were detected in the cerebrospinal fluid (CSF) during the 2nd week after onset of meningitis or later in 4 out of 10 patients, and could be detected as late as 11 and 12 months after meningitis in 2(More)
Two boys, 5 and 18 years old, had had frequent infections from their second month of life and had later suffered from generalized lymphadenopathy, intermittent maculopapular exanthema, anaemia, and weight loss. Histopathological features of lymph nodes were consistent with immunoblastic lymphadenopathy. Immunohistochemistry showed hyperimmune state with(More)
Varicella is a common viral infection in childhood, and acute osteomyelitis is one of the rare but serious complications. We report two cases of osteomyelitis as a complication of varicella. The possibilities and limitations of the different imaging modalities are discussed, as well as imaging findings during the course of this condition.
Paroxysmal cold haemoglobinuria (PCH) is a disease which today is met mainly in its acute form in children. The diagnosis is revealed by a careful serological examination. Case reports of four children with PCH are given in this paper. They all showed typical clinical pictures of PCH, and displayed the expected serological findings, including a bithermic(More)
A total of 664 soil samples distributed among different geographic regions and soil types were collected across Wisconsin to describe the distribution of arsenic relative to parent material, soil texture, and drainage class. Soils from 6 inches in depth were composited, digested in aqua regia, and analyzed for 17 trace elements. Observed soil arsenic(More)
