Case details: A 28-year-old man was admitted to the critical care unit of a university hospital for arrhythmia after ingestion of self-made T. baccata leaf capsules. He rapidly developed cardiovascular collapse requiring mechanical ventilation, high dose intravenous catecholamines and electrical cardioversion. A femoro-femoral VA ECMO was implanted due to severe biventricular dysfunction and ventricular arrhythmia, associated with continuous renal replacement therapy. Taxol A, taxol B and baccatin III were detected and measured in both blood and urine samples by high-performance liquid chromatography tandem mass spectrometry, and kinetics suggested urinary excretion. Two days after hospital admission, VA ECMO and continuous renal replacement therapy were removed with full recovery of cardiac function.
Discussion: Our experience suggests that circulatory assistance by VA ECMO and continuous renal replacement therapy seem to be effective safe second-line therapeutic options in critically ill cases of severe yew intoxication with refractory cardiogenic shock due to arrhythmia. 相似文献
Case history: A 27-year-old man and his 25-year-old wife presented to the emergency department with nausea, vomiting, hypotension, and bradycardia after foraging and ingesting plants that they believed to be a local native species of wild leek.
Methods: We collected and analyzed the implicated fresh plant material and both patients’ serum/plasma. We used liquid chromatography–mass spectroscopy and high-resolution electrospray ionization time of flight tandem mass spectrometry to extract and characterize steroidal alkaloids from the foraged plant and patients’ serum.
Results: Our V. parviflorum samples contained verazine, veratramine, veratridine, and cyclopamine.
Discussion: Steroidal alkaloids have been previously isolated from Veratrum viride and Veratrum album and toxicity has been reported mainly from V. album species.
Conclusion: V. parviflorum toxicity manifests with gastrointestinal and cardiac symptoms. Treatment is symptomatic and supportive as with previous case reports of toxicity with other Veratrum species. 相似文献
Objectives: To examine the effect of external application in pain compared to traditional method.
Design: A double-blind placebo-controlled clinical investigation.
Setting: A public hospital.
Participants: 168 LBP subjects.
Interventions: Assignment: (1) external IFT, (2) placebo external IFT, (3) traditional IFT and (4) placebo traditional IFT. Groups 1 and 3 received 20 min of IFT at 100 Hz and groups 2 and 4 received sham IFT.
Main outcome measures: Before and after IFT session, pain severity (VAS), pressure threshold (PPT), pain distribution and ROM were assessed.
Results: IFT changed all outcomes similarly. VAS and ROM improved statistically, P < 0.03. A trend of better VAS reduced with active IFTs.
Conclusions: No therapeutic difference between the two methods. 相似文献
Design: Cross-sectional, observational study.
Setting: A two-bed emergency care unit.
Subjects: All patients admitted to the unit during one year.
Main outcome measures: Patients’ age and gender, comorbidity, main diagnoses and municipal care level on admission and discharge, diagnostic and therapeutic initiatives, occupancy rate.
Results: Sixty admissions were registered, with total bed occupancy 194 days, and an occupancy rate of 0.27. The patients (median age 83 years, 57% women) had mostly infections, musculoskeletal symptoms or undefined conditions. Some 48% of the stays exceeded three days and 43% of the patients were subsequently transferred to nursing homes or hospitals.
Conclusion: Occupancy rate was low. Patient selection was not according to national standards, and stays were longer. Many patients were transferred to nursing homes, indicating that the unit was an intermediate pathway or a short cut to institutional care. It is unclear whether the unit avoided hospital admissions. 相似文献
Methods: 27 patients with GAVE and 11 control patients without GAVE were evaluated using an endoscopic LDF probe. The probe was placed in the gastric antrum and body in order to calculate standardized mucosal flow rates recorded as perfusion units (PU).
Results: Despite its hyperemic appearance and propensity to bleed, antral blood flow was not increased in GAVE: 115.5 PU (IQR: [94.4, 135.9 PU]) in GAVE versus 123.7 PU (IQR: [109.7, 186.5 PU]) in controls. There was a significant gradient between the gastric body and antral blood flow in GAVE (p < 0.001) that was not evident in controls.
Conclusion: These results indicate that antral mucosal blood flow is not increased in GAVE despite its grossly hyperemic appearance. A mild but statistically significant gradient was noted between the gastric antrum and body in patients with GAVE compared to controls. The pathophysiological significance of this finding is uncertain. 相似文献
Material and methods: Fourteen patients were studied who underwent balloon-occluded retrograde transvenous obliteration (B-RTO) for gastric varices with a gastrorenal shunt. The B-RTO catheter was retained overnight in all patients. Balloon-occluded retrograde venography (B-RTV) was performed to evaluate the degree of thrombus formation. This evaluation was done twice during the overnight B-RTO procedure: A few hours after the procedure and on the following day. Investigated were the degree of thrombus formation observed by the first and second B-RTV, change in the degree of thrombus between the first and second B-RTV, and whether and how much sclerosing agent was administered on the second day.
Results: The first B-RTV showed entire or partial enhancement of the gastric varix in seven (50%) cases and complete or almost complete lack of enhancement in the remaining seven cases. In four of the former seven cases, the second B-RTV showed entire or partial enhancement of the gastric varix, and the sclerosing agent was added. However, in the remaining ten cases, enhancement was almost or completely lacking.
Conclusion: When complete thrombosis is shown on B-RTV obtained a few hours after B-RTO, the addition of a sclerotic agent would be unnecessary. 相似文献
Objectives: The review presents in a series of questions-answers and under a clinical point of view the current data regarding the use of osmolal gap.
Discussion: The definition and the best formula used for the calculation of osmolal gap, the main causes of increased osmolal gap with or without increased anion gap metabolic acidosis, as well as the role of concurrent lactic acidosis or ketoacidosis are presented under a clinical point of view.
Conclusions: The calculation of osmolal gap is crucial in the differential diagnosis of many patients presenting in emergency departments with possible drug or substance overdose as well as in comatose hospitalized patients. 相似文献
Methods: Studies published from 1 January 1987 to 31 December 2015 in English, which comparing plasma/serum PRL levels between SLE group and control group were searched in PubMed, EMBASE and The Cochrane Library databases. Pooled standard mean difference (SMD) with 95% confidence interval (CI) was calculated by fixed-effects or random-effect model analysis. Heterogeneity test was performed by the Q statistic and quantified using I2, publication bias was evaluated using a funnel plot and Egger’s linear regression test.
Results: Five-hundred and forty-seven articles were obtained after searching databases, and 12 studies with 429 SLE patients and 326 controls were finally included. Meta-analysis revealed that, compared with the control group, the SLE group had significantly higher plasma/serum PRL levels (P < 0.001), with the SMD of 1.26 and 95%CI (0.70,1.82). Subgroup analyses showed that SLE patients from Asia and Europe had higher plasma/serum PRL levels. However, no significant change in plasma/serum PRL levels was observed in SLE patients from America (P > 0.05).
Conclusions: Overall, our study suggests that SLE patients have higher plasma/serum PRL level, but with a regional difference. 相似文献
Design and setting: This is a post hoc analysis of a retrospective study that included all cases of CRC and adenomas with high-grade dysplasia (HGD) between 2005 and 2009 in the county of Jämtland, Sweden.
Subjects: All patients with CRC and adenomas with HGD that initially presented with symptoms to primary care and delivered FITs.
Main outcome measure: The likelihood of a positive FIT in cases of CRC and adenomas with HGD; when analysing one, two or three samples.
Results: Of 195 patients, 160 delivered three-sample FITs. Using the 139 cases in which at least one sample was positive, the likelihood of detecting a positive sample upon analysis of only one of the three samples was 0.91 (95% CI: 0.85–0.95), indicating that 13 positive cases may have been missed.
Conclusion: Use of a one-sample FIT instead of a three-sample FIT as a diagnostic aid may result in the missing of one tenth of symptomatic CRCs and adenomas with HGD. 相似文献
Aim: To explore the experiences of individual services participating in the Australian National Palliative Care Standards Assessment Program.
Design: Case study evaluation.
Data sources: Ten case studies from participating services; service self-assessment data; peer mentor reports; in-depth interviews.
Analysis: Time point comparison; thematic analysis of interview data.
Results: A key strength of NSAP was the cycle between data collection, identification of key improvement areas, and development of strategies for improvement. An understanding of NSAP as a continuous quality improvement process and the potential for the integration of other national programs were noted as key service improvement strategies. The use of resources to promote best practice largely relied upon access to the Internet. PMVs were considered successful, contingent on careful matching of mentors to services. The presence of a ‘champion’ within services was perceived as a success factor.
Conclusions: This evaluation informs service improvement in specialist palliative care services through the alignment of continuous quality improvement with National Palliative Care Standards. This may assist development and ongoing revision of continuous quality improvement in the international context. 相似文献
Objectives: To determine the risk of recurrence after a first intentional overdose. Secondary objectives included characterization of the temporal course and potential predictors of repeat overdose, a strong risk factor for death from suicide.
Methods: Design: Population-based cohort study.
Setting: Ontario, Canada, from 1 April 2002 to 31 March 2013.
Participants: All Ontario residents presenting to an emergency department after a first intentional overdose.
Main outcome measures: The incidence and timing of recurrent overdose.
Results: We followed 81,675 patients discharged from hospital after a first intentional overdose. Overall, 13,903 (17.0%) returned with a repeat overdose after a median interval of 288 (inter-quartile range: 62 to 834) days. Of these, 4493 (5.5%) had multiple repeat episodes. Factors associated with repeat self-poisoning included psychiatric care in the preceding year (adjusted hazard ratio [aHR] 1.55; 95% confidence interval [CI] 1.50 to 1.61), alcohol dependence (aHR 1.41; 95% CI 1.35 to 1.46) and documented depression (aHR 1.39; 95% CI 1.34 to 1.44). Female sex, rural residence, lower socioeconomic status, ingestion of psychoactive drugs and younger age were also weakly associated with repeat overdose.
Discussion: Hospital presentation for repetition of intentional overdose is common, with recurrent episodes often far removed from the first. While several factors predict overdose repetition, none is particularly strong.
Conclusion: Secondary prevention initiatives should be implemented for all individuals who present to the emergency department and survive intentional overdose. 相似文献
Pain Pattern Classification (PPC) and Directional Preference (DP) have been shown to be predictive of health care outcomes and serve to guide orthopedic clinical decision making. We conducted a prospective, observational cohort study to verify the association between PPC, DP, and clinical outcomes.
Methods:
Clinical outcome measures including pain intensity and disability were completed at first examination and follow-up by 335 patients. A Pearson’s chi-squared test was used to determine differences in prevalence rates for the categorical variables, and two-sample t-tests were used to determine differences in rates for the continuous variables. A Tukey’s range test was used to determine differences in follow-up pain intensity and disability for neck pain dual-classification schemes.
Results:
The prevalence of DP was 82.4%. The prevalence of CEN, Non-CEN, and Non-Classifiable (NC) was 15.2%, 42.1%, and 25.1%, respectively. The prevalence of DP was lowest for patients with sub-acute symptoms and who were <45 years old. Patients classified as DP CEN had, on average 2.62 NDI units less than patients classified as Non-DP. Patients classified as DP CEN had, on average, 0.90 pain intensity units less than patients classified as Non-DP at follow-up. Patients who demonstrated DP CEN did not have clinically significant lower pain intensity or disability at follow-up than patients who demonstrated Non-DP.
Discussion:
The results of this investigation need to be interpreted with caution with respect to the study design and it’s subsequent strengths and limitations.

Design: An observational study.
Setting: Register-based retrospective quasi-experimental longitudinal follow-up study based on a before–after setting in a Finnish city.
Subjects: Patients who consulted different doctors in a local health care unit.
Main outcome measures: Numbers of monthly visits to different doctor groups in public and private primary care, and numbers of monthly referrals to secondary care ED from different sources of primary care were recorded before and after abrupt implementation of the reverse triage.
Results: The beginning of reverse triage decreased the number of patient visits to a primary ED doctor without increasing mortality. Simultaneously, there was an increase in doctor visits in the adjacent secondary care ED and local private sector. The number of patients who came to secondary care ED without a referral or with a referral from the private sector increased.
Conclusions: The data suggested that the reverse triage causes redistribution of the use of doctors’ services rather than a true decrease in the use of these services. 相似文献
Design: A RAND/UCLA Appropriateness Method was used.
Setting: General practice.
Subjects: A panel of nine experts, mainly general practitioners, was asked to rate the relevance of 64 quality indicators for the diagnosis and antibiotic treatment of acute respiratory tract infections based on guidelines. Subsequently, a face-to-face meeting was held to resolve misinterpretations and to achieve consensus.
Main outcome measures: The experts were asked to rate the indicators on a nine-point Likert scale. Consensus of appropriateness for a quality indicator was reached if the overall panel median rating was 7–9 with agreement.
Results: A total of 50 of the 64 proposed quality indicators attained consensus. Consensus was achieved for 12 indicators focusing on the diagnostic process and 19 indicators focusing on the decision about antibiotic treatment and choice of antibiotics, respectively.
Conclusion: These newly developed quality indicators may be used to strengthen Danish general practitioners’ focus on their management of patients with acute respiratory tract infections and to identify where there is a need for future quality improvements. 相似文献
Methods: Liquid chromatography mass spectrometry (LC-MS) analysis was used as a laboratory reference method to compare precision of PoCT devices using blood samples from 20 healthy volunteers. Accuracy was compared against the LC-MS reference method and a laboratory clinical chemistry platform.
Results: Qualitatively, EasyTouch® GU and UASure were least user-friendly, requiring repeated attempts for accurate use. HumaSens and BeneCheck provided good usability and assay precision. Cross-validation of meter precision with laboratory-based uricase assay gave good correlations between both methods (R2 = 0.8061 and 0.7605, respectively).
Conclusion: UA PoCT meters can be important in managing gout, and the characteristics compared herein may enhance successful patient uptake. 相似文献
Methods: Thirty subjects with neck pain were instructed to grasp and lift an object before and after cervical (n = 15) or sham (n = 15) manipulation. The patients’ PPT, electromyographic (EMG) activity of the upper extremity/scapular muscles, and grip force control were analyzed before and after one session of manipulation.
Results: No significant differences were found in the grip force control, PPT and EMG activity variables between groups.
Discussion: These results suggest that a single session of cervical manipulation may not modify upper limb motor control, more specifically grip force control and EMG activity, in patients with cervical pain. Future studies should investigate potential changes in grip force control in patients with different features of neck pain and/or by applying long-term treatment.

Methods: All subjects were evaluated for fasting blood glucose (FBG), HbA1c, liver enzymes, lipid profile and serum Ang-2.
Results: Mean serum Ang-2 level was significantly higher in hypertensive diabetic subjects. In bivariate analysis in diabetic subjects with cardiovascular risk factors, Ang-2 positively correlated with waist circumference, body mass index (BMI), systolic blood pressure (SBP), FBG, HbA1c and triglycerides. In multivariate linear regression analysis, this association remained significant with FBG and triglycerides. Ang-2 levels were independently associated with CVD risk factors in drug controlled Type 2 diabetes (T2D) subjects.
Conclusions: Further detailed studies in larger population with more attention is needed to consider Ang-2 level as a tool for CVD risk stratification in hypertensive diabetic subjects. 相似文献
Design: Observational before-after study.
Setting: Forty-one nursing homes.
Intervention: MRs performed by multidisciplinary teams during November 2011 to February 2014.
Subjects: In all, 2465 long-term care patients.
Main outcome measures: DRPs identified by explicit criteria (STOPP/START and NORGEP) and drug–drug interaction database; interventions to resolve DRPs; drug use changes after MR.
Results: A total of 6158 DRPs were identified, an average of 2.6 DRPs/patient, 2.0 for regular and 0.6 for pro re nata (prn) drugs. Of these patients, 17.3% had no DRPs. The remaining 82.7% of the patients had on average 3.0 DRPs/patient. Use of unnecessary drugs (43.5%), excess dosing (12.5%) and lack of monitoring of the drug use (11%) were the most frequent DRPs. Opioids and psychotropic drugs were involved in 34.4% of all DRPs. The mean number of drugs decreased after the MR from 6.8 to 6.3 for regular drugs and from 3.0 to 2.6 for prn drugs. Patients with DRPs experienced a decrease of 1.1 drugs after MR (0.5 for regular and 0.6 for prn drugs). The reduction was most pronounced for the regular use of antipsychotics, antidepressants, hypnotics/sedatives, diuretics, antithrombotic agents, antacid drugs; and for prn use of anxiolytics, opioids, hypnotics/sedatives, metoclopramide and NSAIDs.
Conclusion: The medication review resulted in less drug use, especially opioids and psychotropic drugs. 相似文献
Material and methods: We retrospectively reviewed 111 ESCN in 86 patients treated by ESD between September 2007 and April 2013. There were four double cancers, with 107 ESD procedures analyzed.
Results: The en bloc resection rate was 99% (106/107). The R0 resection rate was 93% (99/107). Of 106 specimens resected en bloc, four specimens had a positive horizontal margin, two specimens had non-assessable horizontal margins and one specimen had non-assessable horizontal and vertical margins. One patient with a non-assessable horizontal margin developed local recurrence seven months later, treated by repeat ESD. Delayed bleeding occurred in two procedures (2%), and intra-procedural perforation occurred in four (4%). None required operative repair. Endoscopy trainees performed 33 of 107 (31%) ESD procedures. Post-ESD stenosis requiring dilation occurred following five procedures (5%).
Conclusions: Sodium hyaluronate for ESD of ESCN achieves a high R0 resection rate with a low rate of adverse events. 相似文献
