Raised intracranial pressure in the absence of ventricular dilatation is common in cryptococcal meningitis and associated with increased mortality. We report the case of a patient with HIV-associated cryptococcal meningitis, who developed increasing CSF pressure and visual impairment on therapy despite serial lumbar punctures. Insertion of a temporary lumbar drain controlled the opening pressure and resulted in full visual recovery. The advantages and necessary precautions with this approach are reviewed, and alternative protocols for the use of lumbar drains discussed. 相似文献
The incidence of left ventricular (LV) thrombus formation in ST-segment elevation myocardial infarction (STEMI) patients in the current era of primary percutaneous coronary intervention (PCI) is not well established. We performed a meta-analysis to assess the actual incidence and predictors of LV thrombus by cardiovascular magnetic resonance (CMR) in STEMI treated by primary PCI.
Methods
We searched MEDLINE and EMBASE databases up to February 2018. We included all studies published as a full-text article, reporting the incidence of LV thrombus by CMR within 1 month following acute STEMI in patients treated by primary PCI. A binary random-effects model was used to estimate the pooled incidence of LV thrombus. The diagnostic performance of transthoracic echocardiography (TTE) as compared with CMR was pooled to obtain the sensitivity and specificity of TTE with CMR as the gold standard. Embolic and bleeding complications of LV thrombus were also evaluated.
Results
Ten studies were included in the meta-analysis. The incidence of LV thrombus by CMR in all-comer STEMI patients (n?=?2072) was 6.3% with 96% of LV thrombus occurring in those with anterior STEMI (12.2% incidence). When only anterior STEMI with LVEF<?50% were considered (n?=?447), the incidence of LV thrombus was 19.2%. Compared with CMR, the sensitivity of TTE to detect LV thrombus was 29% with a specificity of 98%. The sensitivity of TTE increased to 70% in those with anterior STEMI and reduced LVEF. LV thrombus resolved in 88% of cases by 3 to 6 months. After 1–2 years follow-up, the embolic complication rate was similar at 1.5% (P?=?0.25) but the bleeding complication rate was significantly higher (8.8% versus 0.5%, P?<?0.001) in the LV thrombus group on triple therapy when compared to the no LV thrombus group on dual antiplatelet therapy.
Conclusion
In the primary PCI era, CMR detection of an LV thrombus post-STEMI remains high with incidence of nearly 20% in anterior STEMI with depressed LVEF. Patients with LV thrombus treated by triple therapy had similar embolic complications but higher bleeding complications than those with no LV thrombus treated with dual antiplatelet therapy. A 3 month follow-up CMR scan to guide anticoagulation duration might help mitigate bleeding risk.
Objective: There is a need to identify safe and effective opioid-sparing multimodal alternative treatment strategies and approaches, including topical analgesics, for opioid-experienced chronic pain patients to mitigate the risk of addiction, misuse, and abuse of opioids.
Methods: This subset analysis from a prospective, observational study evaluated changes in opioid use, other concurrent medication use, and pain severity and interference in opioid-experienced patients (OEP) treated with topical analgesics for chronic pain with measures obtained at baseline and 3- and 6- month follow-up.
Results: The 3-month opioid-experienced patient (3-month OEP) group included 121 patients who completed baseline and 3-month follow-up assessments; 27 opioid-experienced patients completed baseline and 6-month follow-up assessments (6-month OEP). Demographic characteristics, and mean pain severity and interference scores were similar between groups at baseline. After treatment with topical analgesics, 49% of patients in the 3-month and 56% of patients in the 6-month group reported they had completely discontinued use of opioids. In addition, 31% of patients at the 3-month assessment and 30% at the 6-month assessment reported that they were no longer taking any pain medication. Other concurrent medications decreased by 65% after 3 months, and 74% after 6 months. There were statistically significant decreases from baseline in pain severity and interference scores within the 3- (CI:0.7–1.4, 1.4–2.2) and 6-month (CI:0.7–2.4 (severity); CI:1.2–3.5 (interference)) OEP groups.
Conclusions: Opioid use and other concurrent medications decreased among opioid-experienced chronic pain patients after 3- and 6- months of treatment with topical analgesics. Pain severity and interference scores also decreased. The topical analgesics were reported to be effective and safe for the treatment of chronic pain, with randomized controlled trials needed to confirm these findings. 相似文献
Historically, access to primary percutaneous coronary intervention (PCI) for the treatment of patients with ST segment elevation myocardial infarction (STEMI) has been limited in Canada. Recent studies have identified innovative strategies to improve timely access and reduce reperfusion time. Accordingly, the contemporary use of primary PCI treatment in Canada was ascertained.
METHODS:
A cross-sectional survey of all 38 Canadian hospitals that were capable of performing PCI procedures was conducted from June 2007 to November 2007. The survey focused on the practice of primary PCI for patients with STEMI and whether the hospitals had implemented internal strategies to reduce ‘door-to-balloon’ times. Analyses were performed at the level of geographical regions.
RESULTS:
Overall, 71% of PCI hospitals (27 of 38) provided around-the-clock primary PCI for patients with STEMI, but the proportion of PCI hospitals offering this service varied widely, from 33% to 100% across regions. All Canadian PCI hospitals provided around-the-clock rescue PCI treatment to STEMI patients who had failed fibrinolytic therapy. In terms of strategies that are associated with reduced reperfusion time, it was observed that only 42% of PCI hospitals (16 of 38) provided feedback on door-to-balloon time to the emergency department and to the cardiac catheterization laboratories within one week of the primary PCI procedure. Overall, 24% of the hospitals had not adopted any of the four identified strategies to improve door-to-balloon time.
CONCLUSION:
Although the majority of Canadian hospitals with PCI capability provide around-the-clock primary PCI for patients with STEMI, significant variations in this practice exist across the country. Canadian PCI hospitals have not consistently adopted strategies that are associated with improved door-to-balloon time. 相似文献
