Introduction and hypothesis

Women have a lifetime risk of undergoing pelvic organ prolapse (POP) surgery of 11–19%. Traditional native tissue repairs are associated with reoperation rates of approximately 11% after 20 years. Surgery with mesh augmentation was introduced to improve anatomic outcomes. However, the use of synthetic meshes in urogynaecological procedures has been scrutinised by the US Food and Drug Administration (FDA) and by the European Commission (SCENIHR). We aimed to review trends in pelvic organ prolapse (POP) surgery in England.

Methods

Data were collected from the national hospital episode statistics database. Procedure and interventions-4 character tables were used to quantify POP operations. Annual reports from 2005 to 2016 were considered.

Results

The total number of POP procedures increased from 2005, reaching a peak in 2014 (N?=?29,228). With regard to vaginal prolapse, native tissue repairs represented more than 90% of the procedures, whereas surgical meshes were considered in a few selected cases. The number of sacrospinous ligament fixations (SSLFs) grew more than 3 times over the years, whereas sacrocolpopexy remained stable. To treat vault prolapse, transvaginal surgical meshes have been progressively abandoned. We also noted a steady increase in uterine-sparing, and obliterative procedures.

Conclusions

Following FDA and SCENIHR warnings, a positive trend for meshes has only been seen in uterine-sparing surgery. Native tissue repairs constitute the vast majority of POP operations. SSLFs have been increasingly performed to achieve apical support. Urogynaecologists’ training should take into account shifts in surgical practice.

BACKGROUND: Aerosolized antibiotics are a widely recognized treatment for patients with cystic fibrosis (CF). We sought to clarify their role in the treatment of non-CF patients with nosocomial pneumonia by performing a meta-analysis of randomized controlled trials (RCTs) that compared administration of antimicrobials via the respiratory tract (with or without concurrent usage of systemic antibiotics) with control treatment. METHODS: An extensive search of PubMed, Scopus, Cochrane Central Register of Controlled Trials, Current Contents and bibliographies from retrieved publications was made. RESULTS: Five RCTs were included in the meta-analysis. Administration of antimicrobials via respiratory tract (either inhaled or endotracheally instilled) as opposed to control was associated with better treatment success in intention-to-treat [fixed effect model: odds ratio (OR) = 2.39, 95% confidence interval (CI) 1.29-4.44; random effects model: OR = 2.75, 95% CI 1.06-7.17] and in clinically evaluable patients (fixed effect model: OR = 3.14, 95% CI 1.48-6.70; random effects model: OR = 3.07, 95% CI 1.15-8.19). There were no statistically significant differences between therapeutic regimens regarding all-cause mortality (fixed effect model: OR = 0.84, 95% CI 0.43-1.64; random effects model: OR = 0.71, 95% CI 0.27-1.88), microbiological success (fixed effect model: OR = 2.06, 95% CI 0.91-4.68; random effects model: OR = 2.23, 95% CI 0.64-7.71) and toxicity (fixed effect model: OR = 0.34, 95% CI 0.04-2.53; random effects model: OR = 0.36, 95% CI 0.04-3.16). CONCLUSIONS: The limited available evidence seems not to preclude a benefit from the administration of antimicrobial agents via the respiratory tract for treating nosocomial pneumonia.  相似文献

Purpose

Review of the indications for, and the post-operative complications and mortality rates of endovascular techniques for treating abdominal aortic dissection (AAD).

Methods

An electronic health database search was performed using PubMed, Medline and EMBASE for publications on AAD. The search yielded multiple case reports, which were not included here, and 9 recent series with sufficient data for analysis.

Results

The series included in the review reported data on a total of 208 patients. Of the AADs recorded, 182 were spontaneous (87.5%), 13 traumatic (6.25%) and 13 iatrogenic (6.25%), and the majority were of acute presentation (150 patients, 72%). The mean age of the patients was 62.6 years. Hypertension was the most prevalent risk factor (133 patients, 64%). Concurrent aortic aneurysms were more often associated with spontaneous dissection (56 patients, 27%). Open surgical repair was performed in 54 patients (26%), endovascular repair in 94 (45%) and the treatment was conservative in 60 (29%). The in-hospital mortality was 2% for the endovascular group, 5% for the open repair group and ~7% for those receiving conservative treatment. More complications were reported in the patients treated by open surgery than in those undergoing endovascular repair.

Conclusions

Patients with AAD are at considerable risk of complications and in-hospital mortality. Based on current evidence, endovascular treatment appears to be associated with a lower risk of major complications and mortality than open repair or conservative treatment, and the need for secondary intervention is rare.

Autonomic reflexes enable the cardiovascular system to respond to gravitational displacement of blood during changes in posture. Spontaneous oscillations present in the cerebral and systemic circulation of healthy subjects have demonstrated a regulatory role. This study assessed the dynamic responses of the cerebral and systemic circulation upon standing up and the posture dependence of spontaneous oscillations. In ten young healthy volunteers, blood pressure and cerebral haemodynamics were continuously monitored non-invasively using the Portapres and near-infrared spectroscopy (NIRS), respectively. Oscillatory changes in the cerebral NIRS signals and the diastolic blood pressure (DBP) signal have been identified by the fast Fourier analysis. Blood pressure increased during standing and returned to basal level when volunteers sat on a chair. The mean value of cerebral tissue oxygen index (TOI) as measured by NIRS did not demonstrate any significant changes. Oscillatory changes in DBP, oxyhaemoglobin concentration [O2Hb] and TOI showed a significant increase when subjects were standing. Investigation of the low frequency component (approximately 0.1 Hz) of these fluctuations revealed posture dependence associated with activation of autonomic reflexes. Systemic and cerebral changes appeared to preserve adequate blood flow and cerebral perfusion during standing in healthy volunteers. Oscillatory changes in [O2Hb] and TOI, which may be related to the degree of cerebral sympathetic stimulation, are posture dependent in healthy subjects.  相似文献

Intraspinal drug infusion using implantable pumps and catheter systems is a safe and effective therapy for selected pain patients with severe chronic pain. It improves pain relief, reduces drug-related side effects, decreases the need for oral analgesia and enhances quality of life in a segment of chronic pain patients whose pain has not been controlled with more conservative therapies. Intrathecal drug therapy has therefore established its role in the treatment of malignant pain, benign pain and severe spasticity. Careful patient selection and management as well as a multidisciplinary approach are determinants of successful treatment. Current practices for patient selection and management, screening, drug selection, dosing and implantation for intrathecal drug delivery systems are discussed.  相似文献

OBJECTIVE: To investigate hypothalamic-pituitary-adrenal axis function in patients requiring mechanical ventilation for traumatic brain injury and to assess the relation of hypothalamic-pituitary-adrenal axis abnormalities with vasopressor dependence and peripheral cytokine levels. DESIGN: Prospective study. SETTING: General intensive care unit in a university teaching hospital. PATIENTS: Forty patients (33 men and 7 women) with moderate to severe traumatic brain injury (mean age, 37 +/- 16 yrs) were studied the day after termination of mechanical ventilation (7-60 days after trauma). INTERVENTIONS: First, a morning blood sample was obtained to measure baseline cortisol, corticotropin, interleukin-6, and tumor necrosis factor alpha. Subsequently, 1 microg of synthetic corticotropin was injected intravenously, and 30 mins later, a second blood sample was drawn to determine stimulated plasma cortisol. Based on data derived from healthy volunteers, patients having stimulated cortisol levels <18 microg/dL were defined as nonresponders to the low-dose stimulation test. Thirty-one patients underwent also a human corticotropin releasing hormone test. MEASUREMENTS AND MAIN RESULTS: In traumatic brain injury patients, mean baseline and low-dose stimulation test-stimulated cortisol levels were 17.2 +/- 5.4 microg/dL and 24.0 +/- 6.6 microg/dL, respectively. The median increment in cortisol was 5.9 microg/dL. Basal corticotropin levels ranged from 3.9 to 118.5 pg/mL. Six of the 40 patients (15%) failed the low-dose stimulation test. The human corticotropin releasing hormone test (performed in 26 responders and five nonresponders) revealed diminished cortisol release only in the low-dose stimulation test nonresponder patients. Corticotropin responses to corticotropin releasing hormone were consistent with both primary (three patients) and/or secondary (two patients) adrenal dysfunction. In retrospect, nonresponders to the low-dose stimulation test more frequently required vasopressors (6/6 [100%] vs. 16/34 [47%]; p =.02) and for a longer time interval (median, 0 vs. 293 hrs; p =.006) compared with responders. Furthermore, nonresponders had higher interleukin-6 levels compared with responders (56.03 vs. 28.04 pg/mL; p =.01), whereas tumor necrosis factor alpha concentrations were similar in the two groups (2.42 vs. 1.55 pg/mL; p =.53). CONCLUSIONS: Adrenal cortisol secretion after dynamic stimulation is deficient in a subset of critically ill patients with moderate to severe head injury. This disorder is associated with prior vasopressor dependency and higher interleukin-6 levels.  相似文献

Objective: To develop a clinical and prognostic scoring system predictive of survival after resection of intrahepatic cholangiocarcinomas (ICC). Patients: Two hundred and one consecutive ICC patients (83 from Essen, Germany, 54 from New York, USA and 64 from Chiba, Japan). The scoring systems were developed utilizing the data set from Essen University and then applied to the data sets from Mount Sinai Medical Center and Chiba University for validation. Eighteen potential prognostic factors were evaluated. Statistical analysis included multivariable regression analyses with the Cox proportional hazard model, power analysis, internal validation with structural equation modelling bootstrapping and external validation. The prognostic scoring model was based mainly in pathological and demographical variables, whereas the clinical scoring model was based mainly in radiological and demographical variables. Results: Gender (P=0.0086), UICC stage (P=0.0140) and R‐class (P=0.0016) were predictive of survival for the prognostic scoring model, while gender (P=0.0023), CA 19‐9 levels (P=0.0153) and macrovascular invasion (P=0.0067) were predictive of survival for the clinical scoring model. Prognostic points were assigned as follows: female:male=1:2 points, UICC (I–II):UICC (III–IV)=1:2 points and R0:R1=1:2 points. Clinical points were allocated as follows: female:male=1:2 points, CA 19‐9 (<100 U/ml):CA 19‐9 (≥100 U/ml)=1:2 points and no macrovascular invasion:macrovascular invasion=1:2 points. Prognostic groups with 3–4, 5 and 6 points (P=0.000001) and clinical groups with 3–4 and 5–6 points (P=0.0103) achieved statistically significant difference. Conclusions: We propose a clinical and prognostic scoring system predictive of long‐term survival after surgical resections for ICC.  相似文献

Background  

Differential diagnosis of patients with lung infiltrates remains a challenge. Triggering receptor expressed on myeloid cells (TREM)-1 is a neutrophil and monocyte receptor up-regulated during infection. The aim of this study was to evaluate the diagnostic accuracy of TREM-1 and of C-reactive protein (CRP) from patients with lung infiltrates to discern community acquired lung infections.  相似文献
