The pre-eruptive illness of measles.
According to Sydenham (1717), the rash of measles appears on the fourth, or sometimes the fifth, day of the illness. This has remained the standard teaching of most of the authorities on infectious diseases and paediatrics (e.g. Sheldon, 1948; Banks, 1949; Harries and Mitman, 1951; Top, 1955). However, Panum (1847), in his classic report of a measles epidemic, states that although the prodromal...
متن کاملHæmaturia in the Pre-Eruptive Stage of Measles
On the 1st January, 1931, a boy, six years of age, became ill with sneezing, indefinite malaise and slight backache. There had been no previous illness. On the evening of the second day he passed, per urethram, without pain, what was thought to be pure blood. I saw him at 8.30 p.m. and found him in bed with a temperature of 101'4? F. and a pulse-rate of 112. The pharynx and nose were congested,...
متن کاملHigh pre-eruptive water contents preserved in lunar melt inclusions.
The Moon has long been thought to be highly depleted in volatiles such as water, and indeed published direct measurements of water in lunar volcanic glasses have never exceeded 50 parts per million (ppm). Here, we report in situ measurements of water in lunar melt inclusions; these samples of primitive lunar magma, by virtue of being trapped within olivine crystals before volcanic eruption, did...
متن کاملRelationships between pre-eruptive conditions and eruptive styles of phonolite-trachyte magmas
Phonolitic eruptions can erupt either effusively or explosively, and in some cases develop highly energetic events such as caldera-forming eruptions. However, the mechanisms that control the eruptive behaviour of such compositions are not well understood. By combining pre-eruptive data of well studied phonolitic eruptions we show that the explosive-effusive style of the phonolitic magma is cont...
متن کاملTreatment of an undiagnosed pre-eruptive intra-coronal radiolucency.
Bitewing radiographs have been one of the dentist’s chief diagnostic tools in the dental clinic. They increase detection of interproximal caries approximately two-fold when compared to clinical examination alone. To a much lesser extent, the bitewing may be used to diagnose occlusal caries. The dentist examining a bitewing radiograph will pay attention to the alveolar crests thus assessing peri...
