This study examined the use and effectiveness of the Alert assessment form. The form is part of the Alert system, used by one large acute care hospital to identify patients with a propensity for violence. All reported incidents of patient violence from August 1, 2003, through December 31, 2004, were included in patient charts. One hundred seventeen violent patient charts were reviewed and compared with 161 non-violent patient charts, randomly chosen from the same time period. Overall use of the Alert assessment form for violent and non-violent patients was 75.7% and 35.4%, respectively. The assessment form was found to have moderate sensitivity (71%) and high specificity (94%). It is reasonably effective in identifying potentially violent or aggressive patients when it is used according to protocol. Efforts to improve the tool are warranted, as is evaluation of its benefit in settings with low prevalence of violence. Also, greater effort must be taken to prevent violence once an aggressive patient has been identified. 相似文献

Allergens of Parietaria judaica pollen extract have been identified and characterized biochemically. Two main allergenic components, A1 and A2, have been found by crossed-radioimmunoelectrophoresis and demonstrated to be spread in a wide range of pH. Immunoblotting studies revealed that at least eight SDS-denatured polypeptides show IgE-binding activity. The one exhibiting the highest allergenic activity, named Pj10 (MW 10,000 daltons) was found in all the fractions when the pollen extract was fractionated by chromatofocusing. Bidimensional electrophoretic analysis suggested that Pj10 either can form homopolymeric proteins of different molecular weights or can be associated to a number of proteins by disulfide bridges. Furthermore, Pj10 is the main molecular structure with IgE-binding activity in the two allergenic components A1 and A2 defined by immunological criteria. 相似文献

Monoclonal antibodies to three distinct epitopes on human IgE: their use for determination of allergen-specific IgE 总被引:7,自引:0,他引:7
Three different monoclonal antibodies (MAb) against human immunoglobulin E have been obtained which specifically bind to human myeloma and polyclonal IgE. The antibodies showed high avidities for soluble IgE (0.7 X 10(9) to 3.3 X 10(9) M-1). These MAb defined three distinct epitopes on IgE. A mixture of these antibodies in combination with an 125I-labelled anti-mouse Kappa chain MAb has been used to measure allergen-specific IgE. This determination was performed by a solid-phase radioimmunoassay using allergen extracts coated to either chemically activated paper discs or to polyvinyl chloride wells. This method is 4-10 times more sensitive than other previously reported procedures. A similar technique has also been applied to detect individual allergens in immunoblots of allergen extracts. 相似文献

In a pilot study, the metabolic effects of continuous subcutaneous insulin infusion (CSII) versus intensive subcutaneous insulin therapy (ISIT) started at diagnosis in patients with Type 1 diabetes and continued for a 2-year period were evaluated and compared. Twenty-three patients (between 12 and 35 years old, mean +/- SD 18.4 +/- 9 years) were randomized into two treatment groups (CSII vs. ISIT), and both received supplemental nicotinamide (NA), 25 mg/kg of body weight. CSII was started immediately after admission to the hospital. Parameters of metabolic control [insulin dose, hemoglobin A1c (HbA1c), and C-peptide] were evaluated for a 2-year follow-up period. Data are presented for a total of 19 patients who remained in the study for its duration. Two years after diagnosis, mean +/- SD HbA1c was 6.3 +/- 0.5% and 6.2 +/- 0.3% for the CSII and ISIT groups, respectively (p=not significant). Compared with baseline values, an increase of baseline C-peptide of 38% for the CSII group and 27% for the ISIT group was observed; however, the difference between the groups was not significant. The insulin requirement for the entire duration of the study, but not at entry and 3 months, was significantly higher in CSII compared with ISIT patients (0.62 +/- 0.4 IU/kg/day vs. 0.3 +/- 0.4 IU/kg/day, respectively; p<0.01). After trial completion patients on CSII continued with this mode of therapy. Implementation of CSII as well as ISIT at diagnosis of Type 1 diabetes and continuation for 2 years thereafter achieved similar and optimal metabolic control, but more insulin was required with the CSII group. Both types of intensive insulin therapy combined with NA are able to preserve C-peptide secretion or even increase baseline levels for up to 2 years after diagnosis. 相似文献

Aneurysms of the aorta are frequent and treatment is well known, correlated with a statistical risk of rupture. Pulmonary artery aneurysms are less frequent. They may occur in connection with other conditions (infection, cardiopathy, notably pulmonary artery hypertension, endovascular trauma) or much more exceptionally regarded as idiopathic. Chest x-ray, CT-scan and digitalized pulmonary angiography and echocardiography give the diagnosis and help evaluate extension and localization. We report the case of a 72-year-old woman who developed idiopathic aneurysm of the left pulmonary artery which was discovered fortuitously. Because of the stability of the lesion and the lack of any worsening factor, we decided not to operate this high-risk patient. After 3 years, no complication has been observed and the CT-scan shows no evolution. In case of proximal idiopathic aneurysm of the pulmonary artery, the indication of surgery should be discussed. 相似文献

The authors report the case of a 70 year old man with a past history of nucleation of the left eye thirty years previously, in whom two masses, one in the right atrium and the other in the left ventricle, were chance findings on transthoracic echocardiography. After surgery, during which the right atrial tumour was removed and the left ventricular tumour biopsied, histology confirmed the malignant melanomatous nature of the tumours. Further investigations did not detect a primary tumour or other secondary ones. The choroidal origin of these metastases cannot be excluded. After 5 years follow-up, the patient remains in good general condition and the tumours have not recurred or progressed. The literature is reviewed with reference to this case report. 相似文献

Cardiogenic shock in the acute phase of myocardial infarction still carries a high mortality. In young patients who cannot be revascularised by angioplasty, when medical therapy is failing, some workers recommend an energetic approach, even cardiac transplantation, often with the bridge of mechanical cardiac assistance. This is not possible everywhere, thus preventing possible myocardial salvage and resulting in fairly high mortality. The authors report two cases in which endoluminal revascularisation was not possible and so complete surgical revascularisation with left ventricular assistance was chosen. The two patients survived and one was successfully transplanted electively. This management may be proposed in young patients with multiple occlusions of large coronary arteries in post-infarction cardiogenic shock when medical management is failing despite intra-aortic balloon pumping. 相似文献

ObjectivesTo determine the influence of maturational status on the release of cardiac troponin T (cTnT) induced by a bout of 30 min, high-intensity, continuous exercise.DesignQuasi-experimental, cross-sectional study.MethodsSeventy male, young, well trained swimmers (age range 7–18 years, training experience 1–11 years) were classified by maturational stages: Tanner stage I (n = 14), II (n = 15), III (n = 15), IV (n = 13), and V (n = 13). Participants underwent a distance-trial of 30 min continuous swimming, and cTnT was measured before, immediately after and 3 h after exercise. Changes in cTnT over time were compared among groups, and associated with exercise load.ResultsBasal cTnT was higher in Tanner-V (3.8–8.1 ng/L) compared with I (1.5–5.5 ng/L, p < 0.001), II (1.5–4.5 ng/L, p < 0.001) and III (1.5–6.8 ng/L, p = 0.003), and in IV (1.5–6.3 ng/L) compared with II (p = 0.036). Maximal elevations of cTnT from baseline were notable (p < 0.001) and comparable among maturational stages (p = 0.078). The upper reference limit for myocardial injury was exceeded in 35.7% of the participants, without differences among groups (p = 0.18). Baseline cTnT correlated with participant characteristics, and maximal cTnT elevations from baseline with exercise internal load (%HRpeak, rs = 0.34, p = 0.003; %HRmean, rs = 0.28, p = 0.02).ConclusionsMaturational status influences positively absolute pre- and post-exercise cTnT but not its elevation after a bout of 30 min, high-intensity, continuous exercise. 相似文献
