Migraine is a subjective complaint and no laboratory test has until now been of value. The aim of the present study is to evaluate whether histamine inhalation may be used as a diagnostic test for migraine. In a double blind study design, 15 migra neurs and 15 control subjects scored headache intensity and characteristics before, during, and in the subsequent 12 h after inhalation of increasing doses of histamine (0, 2, 4, 8, 16, 32 and 64 mg/ml). During the histamine inhalations, headaches increased dose-dependently in both groups Eleven of the migraineurs and eight of the healthy controls experienced headaches after the inhalations These headaches fulfilled the IHS criteria for migraine without aura in six of the migraineurs, but in none of the control subjects. Using this as a test parameter, the specificity of the test was 1, but the sensitivity was only 0.4. Our results indicate that histamine inhalation is a specific but insensitive laboratory test for migraine. Migraineurs should be informed about the risk of a migraine attack being provoked before histamine inhalation in pulmonary laboratories. 相似文献

Background
The potential synergistic effects of multiple dietary and physical activity behaviours on the risk of chronic conditions and health outcomes is a key issue for public health. This study examined the prevalence and clustering patterns of multiple health behaviours among a sample of adolescents in the UK. 相似文献996.

Background-
The aim of the study was to develop quality indicators that can be used for quality assessment of registries of occupational diseases in relation to preventive policy on a national level. The research questions were: 1. Which indicators determine the quality of national registries of occupational diseases with respect to their ability to provide appropriate information for preventive policy? 2. What are the criteria that can distinguish low quality from high quality? 相似文献997.
Background
Because of the demographic changes, appropriate measures are needed to prevent early exit from work and to encourage workers to prolong their working life. To date, few studies have been performed on the factors motivating continuing to work after the official age of retirement. In addition, most of those studies were based on quantitative data. The aims of this study were to examine, using both quantitative and qualitative data: (1) the reasons for voluntary early retirement; (2) the reasons for continuing working life after the official retirement age; and (3) the predictive value of the reasons mentioned. 相似文献998.

A total of 164 consecutive patients with a range of biopsy-proven locally advanced or metastatic cancers were interviewed t o assess quality of life using the Rotterdam Symptom Check List (RSCL) at three longitudinal time intervals during a course of palliative radiotherapy. Of the 164 patients, 120 were able to complete all 3 question-naires. Paired t-tests were used t o assess the significance of changes in the patients mean scores over time. Of the 33 symptoms assessed in the RSCL, changes in the degree o f symptomatology were highly consistent with changes expected in clinical practice, as a result of either disease progression or side effects o f treatment. It is concluded that the RSCL provides a practical assessment of various symptoms in patients receiving palliative radiotherapy, and that the changes in symptom profile over time are relevant to clinical practice. The RSCL has never been previously used in the assessment of palliative radiotherapy, and the present study validates this instrument. 相似文献

summary In an attempt to draw the clinician's attention to the coronoid process site While evaluating the aetiology of the restriction of mandibular opening, four cases are illustrated. These cases represent a diversity of causes hampering the free rotational movement of the coronoid process in space during jaw function. Case 1 is an example of unilateral hyperplastic coronoid process and osteochondroma; case 2 shows unusually shaped short and divergent coronoid processes combined with a bucally displaced maxillary third molar on one side; cases 3 and 4 represent an anatomical variation of an extremely narrow vestibular space due to the close proximity of the medial aspect of the coronoid process to the distal molar. It is suggested that each clinical examination include the width of the buccal vestibular space while performing mandibular movements. 相似文献
