念珠菌性阴道炎菌种分布及耐药性

目的了解本地区妇女泌尿生殖道念珠菌感染情况及对常用药物的耐药性。方法收集我院普妇科、阴道炎科、阴道感染科的781例女性泌尿生殖道标本进行细菌及真菌培养,并就真菌阳性的标本进行药敏实验。结果 781例标本中,共检出念珠菌阳性120例,阳性率15.4%;耐药率由高到低依次为:伊曲康唑(16.7%)、氟康唑(12.5%)、咪康唑(5.8%)、5-氟胞嘧啶(3.3%)、酮康唑(2.5%)、两性霉素B(0)。结论妇科念珠菌感染以白色念珠菌为主,但非白色念珠菌感染比例有所上升。进行菌种鉴定和药敏实验有利于指导临床合理用药。     

The utility of post-operative hip radiographs in patients treated with hip hemiarthroplasty for femoral neck fractures

BackgroundPatients treated with hip hemiarthroplasty for low energy femoral neck fractures routinely undergo hip radiographs at each postoperative clinic visit regardless of history and physical findings. No studies to date have evaluated the effectiveness of this accepted practice. The goal of this study was to identify the postoperative utility of both history and physical (H/P) and hip radiographs in the treatment course of patients treated with hip hemiarthroplasty for low energy femoral neck fractures.MethodsA retrospective chart review was performed on consecutive patients treated with hip hemiarthroplasty for low energy femoral neck fractures. An abnormal H/P and hip radiographs as well as a change in treatment course were recorded at each clinic or emergency department visit.ResultsFive hundred and eighty-three patients met inclusion criteria, consisting of 1177 clinic and 50 emergency department (ED) visits. An abnormal radiograph in the presence of a normal H/P did not lead to a change in treatment course. An abnormal H/P alone changed treatment course in 28 (3%) clinic visits and 18 (36%) ED visits. An abnormal H/P and the presence of an abnormal hip radiograph changed the treatment course in 23 (2%) clinic visits and 18 (36%) ED visits. In only one case − 0.3% of abnormal radiographs or 0.08% of 1177 clinic visits - did an abnormal hip radiograph change treatment course in the setting of an abnormal H/P within 6 months from surgery. The average cost of a series of hip and pelvis radiographs was $242.ConclusionsAbnormal radiographs do not change treatment course in the presence of a normal H/P. Hip radiographs obtained in clinic within 6 months of surgery rarely lead to a change in treatment course and thereby are a source of excess cost and radiation exposure to the patient.     

Proposal for a New Vesical Imaging-Reporting and Data System (VI-RADS)-Based Algorithm for the Management of Bladder Cancer: A Paradigm Shift From the Current Transurethral Resection of Bladder Tumor (TURBT)-Dependent Practice

Transurethral resection of bladder tumor (TURBT) is the essential first step in the current algorithm for the management of bladder cancer (BC). However, despite its necessity and significance, TURBT has several limitations, including cost, hospitalization, anesthesia, potential complications such as bladder perforation, and delay to radical cystectomy. The Vesical Imaging Reporting and Data System (VI-RADS) was developed to standardize the reporting of multiparametric magnetic resonance imaging for BC, and its diagnostic accuracy to predict muscle invasion has been validated. Given the high sensitivity of VI-RADS ≥ 3 and high specificity of VI-RADS ≥ 4 as clinically relevant cutoff values, we herein propose a new VI-RADS-based algorithm for the management of BC. Using this algorithm, patients with VI-RADS ≤ 2 may not need to undergo sampling of the detrusor muscle nor second TURBT even if there is no muscle in the initial TURBT specimen, whereas patients with VI-RADS ≥ 4 may skip conventional TURBT aimed at pathologic confirmation of muscle invasion and immediately undergo radical cystectomy. Our newly proposed algorithm enables the avoidance of unnecessary deep resection or second TURBT as well as delay to radical cystectomy. The VI-RADS-based algorithm enables a paradigm shift from the current TURBT-dependent practice in the management of BC.     

Replacing risk-based early-onset-disease prevention with intrapartum group B streptococcus PCR testing

Objective: To evaluate the effect of a rapid PCR-based group B streptococcus (GBS) test on length of stay in hospital among newborns, antibiotic use, and GBS-early-onset-disease (EOD) incidence.

Methods: We conducted a before and after service evaluation including term deliveries between 1st January and 12th November 2014 (6688 deliveries). Length of stay in the hospital, GBS-EOD incidence and antibiotic use were evaluated.

Results: We recorded three confirmed and 74 possible cases of GBS-EOD in Phase 1, and 85 possible cases in Phase 2. In newborns with suspected infection, the introduction of the rapid test was related to a decreased length of stay on the pediatric care unit by 1.16 days (p?=?0.01), and an increase in the length of stay on the mother-and-baby ward by 1.11 days (p?Conclusion: The introduction of a point of care test was associated with a reduction in length of stay in the pediatric care unit, without an increase in antibiotic use. This test could improve the accuracy of GBS colonization detection, and help to prevent intrapartum transmission as no verified GBS-EOD cases were recorded with the intrapartum PCR algorithm.
