In many ways, the entire purpose of a radiological exam is to rule out suspected disease and help the attending physician make a definitive diagnosis and proceed with treatment. Radiologists typically only see images and part of the clinical picture. From a pure radiological perspective, it is no...
4 To rule in a diagnosis, we would expect a much higher positive LR (eg, > 10) for whoop and posttussive vomiting. Similarly, although the absence of paroxysmal cough modestly decreases the likelihood of pertussis, it is not sufficient to rule out the diagnosis. As shown in Table 1, ...
If ACS was "ruled out" in the 60 (4.3%) patients where clinicians perceived that the diagnosis was "definitely not" ACS , a sensitivity of 98.0% and negative predictive value of 95.0% could have been achieved. If ACS was only ruled out in patients who also had no electrocardiographic ( ...
6 Overall, the sensitivity of each rule is higher than current practice, where it has been estimated that the diagnosis is missed on first visit in at least 5% of patients with subarachnoid hemorrhage.6 Although emergency physicians have reported that a rule with 99% sensitivity is acceptable, ...
The negative predictive value of spiral computed tomography for the diagnosis of pulmonary embolism in patients with nondiagnostic ventilation-perfusion scans Background: There is no noninvasive method to rule out pulmonary embolism when the clinical suspicion for pulmonary embolism is high. We did a ...
(Hb A1c) (≥6.5%) to these algorithms did not change these estimates; however, 50 patients with previously unknown diabetes may have been identified if Hb A1c was measured.CONCLUSIONS:Algorithms incorporating glucose with cTn may lead to an earlier MI diagnosis and rule-out for MI/cardiovascular...
Conclusions: In MW patients, customized PCT cut-off levels provide better accuracy than customary levels adopted from ICU, and TRACE technology seems to offer a wider analysis range. 展开 关键词: cut-off diagnosis medical ward procalcitonin sepsis ...
Methods We prospectively measured TnI (AccuTnI+3™, Beckman Coulter) at serial time intervals in 1929 subjects with chest pain or equivalent ischemic symptoms suggestive of acute coronary syndromes at 14 medical centers. Diagnosis was adjudicated by an independent central committee. Results TnI ≥ ...
We describe here the development, verification and validation of the SLE-key® rule-out test for a definitive rule-out of a diagnosis of systemic lupus erythematosus (SLE). The test uses the proprietary iCHIP® micro-array technology platform (Fattal et al., 2010) to identify discriminating...
The diagnosis and management of asthma is much tougher in older patients. Half the elderly individuals with asthma have not been diagnosed, yet their quality of life is substantially impaired. Primary care physicians should, ther... Enright,L Paul - 《Curr Opin Allergy Clin Immunol》 被引量: ...
