An in vitro is described that attempts to detect patients with a potential for adverse systemic reactions to contrast material. This test involves measuring the rate of conversion of prekallikrein to kallikrein under certain standard conditions. In a preliminary retrospective study, the test could be used to identify such patients with a sensitivity of 88%, a specificity of 82%, and a predictive value of 79%. 相似文献

Kirov R Kinkelbur J Heipke S Kostanecka-Endress T Westhoff M Cohrs S Ruther E Hajak G Banaschewski T Rothenberger A 《Journal of sleep research》2004,13(1):87-93
The aim of the study was to characterize the sleep pattern in children with attention deficit/hyperactivity disorder (ADHD). By means of polysomnography (PSG), sleep patterns were studied in 17 unmedicated preadolescent boys rigorously diagnosed with ADHD and 17 control boys precisely matched for age and intelligence. Although ADHD children did not display a general sleep alteration, major PSG data showed a significant increase in the duration of the absolute rapid eye movement (REM) sleep and the number of sleep cycles in ADHD group when compared with controls. In addition, REM sleep latency tended to be shorter in ADHD children. These results suggest that in ADHD children, a forced REM sleep initiation may produce a higher incidence of sleep cycles and may also contribute to an increased duration of the absolute REM sleep. The overall pattern of the findings implies that a forced ultradian cycling appears characteristic for the sleep in ADHD children, which may be related to alterations of brain monoamines and cortical inhibitory control accompanying the ADHD psychopathology. 相似文献

West Nile virus 总被引:1,自引:0,他引:1
West Nile virus infection has quickly become a feared cause of neurologic disability and death, particularly when it presents with encephalitis. Recent epidemics in endemic regions of Eurasia and Africa, as well as its recent spread to North America, have highlighted the need for all physicians to be aware of its clinical presentation and course. In particular, because of the increased susceptibility of West Nile virus infection during outdoor activities, as well as during travel to the Middle East and Southeastern Europe, military physicians should be informed about case recognition, management, and prevention to maintain the health of soldiers and their families. 相似文献

Trauma care in Germany 总被引:10,自引:0,他引:10
Trauma Care in Germany fulfils all requirements to deal with injured young and mobile individuals as well as with an increasing number of injured elderly patient. Furthermore, it is prepared to cope with mass casualties of injured. As a public task the Trauma System in Germany is well organized and follows clear cut demands. To perform technical and medical therapy at highest available level as soon as possible, a ground system of physician staffed ambulances is supported by a network of physician-staffed HEMS all over Germany. Therefore, enormous efforts in financing, basic research and quality management have been undertaken during recent years to create such a sophisticated rescue system. 相似文献

Short-term quality of life following abortion is poorly characterized. We conducted a prospective cohort study to evaluate 97 U.S. women who selected either medical abortion with mifepristone and misoprostol or surgical abortion up to 9 weeks gestation in a private-practice setting. Women choosing medical abortion and those choosing surgical abortion with local anesthesia were similar on most baseline characteristics. Eighty-five participants completed a standardized quality of life assessments three times over 1 month. The 30-item questionnaire yielded scores for global health, emotional, social, cognitive and physical functioning and for specific symptom scales. At baseline, participants reported many symptoms and functional limitations during the previous week. Subjects in both treatment groups experienced clinically and statistically significant improvements on all scales at follow-up. Surgical abortion patients had worse scores on three of five function scales and several symptom scales at baseline compared to medical abortion patients. Differences in baseline scores between the medical and surgical abortion patients disappeared during follow-up. A surprising finding was that partner knowledge of the pregnancy at the time the abortion appointment was made was associated with significantly worse scores on most of the function and symptom scales. These results provide substantial reassurance that women undergoing abortion experience a marked improvement in their quality of life after the abortion. Women choosing medical or surgical abortion report very similar quality of life improvements. 相似文献

OBJECTIVE: To identify factors associated with ovarian follicle density in women of reproductive age. DESIGN: Women undergoing incidental oophorectomy responded to structured interviews. Grossly normal ovaries were sectioned and assessed for follicle density. SETTING: University hospital. PATIENT(S): 102 women undergoing hysterectomy with incidental oophorectomy who had morphologically normal ovaries. MAIN OUTCOME MEASURE(S): Follicle density, age, parity, oral contraceptive use, body size, smoking, and alcohol consumption. RESULT(S): Follicle density decreased with age and with current or past cigarette smoking. Other factors were not associated with follicle density, although the study had adequate power to detect only strong associations. CONCLUSION(S): Some of the adverse effects of smoking on reproductive health may be due to irreversible follicular depletion. 相似文献

Diet and cancer prevention: the fiber first diet 总被引:3,自引:0,他引:3
Diet can play a major role in cancer prevention. The international
differences in cancer incidence are largely accounted for by lifestyle
practices that include nutrition, exercise, and alcohol and tobacco use.
About 50% of cancer incidence and 35% of cancer mortality in the U.S.,
represented by cancers of the breast, prostate, pancreas, ovary,
endometrium, and colon, are associated with Western dietary habits. Cancer
of the stomach, currently a major disease in the Far East, relates to
distinct, specific nutritional elements such as excessive salt intake. For
these cancers, information is available on possible initiating genotoxic
factors, promoting elements, and prophylactic agents. In general, the
typical diet in the United States contains low levels of the potent
carcinogenic agents, heterocyclic amines, formed during the cooking of
meats. It provides only about half the potent appropriate fiber intake and
is high in calories. About twice as many calories as would be desirable
come from fat, certain kinds of which enhance the development of cancers.
Other foods with functional properties, such as soy products and tea, can
be beneficial. To achieve reduction in risk of certain cancers, diet must
be optimized, primarily to reduce caloric intake and the fat component. The
latter should be 20% or less of total caloric intake and fiber should be
increased to 25- 35 g per day for adults. One approach to achieving these
goals is the Fiber First Diet, a diet designed around adequate fiber intake
from grains, especially cereals, vegetables, legumes, and fruits, which
thereby reduces both calorie and fat intake. Such dietary improvements will
not only reduce cancer and other chronic disease risks, but will contribute
to a healthy life to an advanced age. A corollary benefit is a lower cost
of medical care.
