ABSTRACT Manual treponemal and nontreponemal serologic testing has historically been used for the diagnosis of syphilis. This approach is simple and reproducible but labor intensive. Recently, the FDA cleared the fully automated BioPlex 2200 Syphilis Total & RPR assay for the detection of treponemal and nontreponemal antibodies. We evaluated the clinical performance of this assay at a tertiary medical center with a high syphilis prevalence. Prospective consecutively collected (n = 400) and known RPR-positive (n = 100) specimens were compared using predicate manual rapid plasma reagin (RPR) and fluorescent treponemal antibody absorption (FTA) methods and the BioPlex 2200 Syphilis Total & RPR assay. Positive and negative percent agreements (PPA and NPA, respectively) between the assays were calculated. The PPA and NPA between the manual and BioPlex 2200 RPR results for the prospective population were 85% (17/20; 95% confidence interval [CI], 69% to 100%) and 98% (373/380; 95% CI, 97% to 99%), respectively. The PPA for the manual RPR-positive population was 88% (88/100; 95% CI, 82% to 94%). Overall, the manual and BioPlex 2200 RPR titers demonstrated 78% (99/127) concordance within ±1 dilution and 94% (120/127) within ±2 dilutions. An interpretation of the syphilis serologic profile using the traditional algorithm showed a concordance of 99.5% in the prospective population and 85% in the manual RPR-positive cohort. The performance of the BioPlex 2200 Syphilis Total & RPR assay is comparable to those of manual methods. The high NPA of this assay combined with the ability to automate a historically labor-intensive assay is an appealing attribute for syphilis screening in a high-volume laboratory.

Syphilis Screening

It remains unidentified why this patient has an extremely high Rapid Plasma Reagin Titer (RPR) 1: 2048. A false positive result was ruled out by a Treponemal test. To ensure accuracy, repeat tests were requested for both the Non-Treponemal and Treponemal Tests in the same laboratory, and the results came back the same. In the Traditional Algorithm, Positive Nontreponemal Syphilis screening tests are confirmed by Treponemal tests, although the latter is not quantitative. The lack of full sensitivity in the Traditional Algorithm Testing has led the CDC and some other centers to adopt Reverse Sequence Testing. The resurgence of syphilis after 20 years could lead to mutagenic strain thus making it relevant for a need for heightened awareness.

A total of 1,020 serum and plasma specimens were tested using the Venereal Disease Research Laboratory (VDRL), Rapid Plasma Reagin (RPR) card, Reagin Screen (RST) and Fluorescent Treponemal Antibody-Absorption (FTA-ABS) tests. In 257 normal patients, all screening tests were nonreactive; the FTA-ABS test was reactive for one patient. In 588 patients with treated and untreated syphilis, the RST results were 91.7% in agreement with the VDRL and RPR results. In 175 patients with diseases that cause biological false reactions, the RST was 94% in agreement with the other screening tests. The titer of the RST was within one dilution of the corresponding VDRL titer in 91.7% of the 360 speciments tested and within one dilution of the RPR titer in 96.9% of 358 specimens quantitated by both tests.

Esophageal resection with reconstruction is complex surgical procedure with high rate of postoperative morbidity, with decreasing mortality rate during last decades, particularly in high-volume hospitals. Numerous preoperative, intraoperative and postoperative factors have contribute to incidence and type of complications. Intraoperative haemorrhage and tracheobronchial lesions could be avoid by good surgical judgement and operative technique. Pulmonary complications are often, with multifactorial etiology, and they are the main cause of postoperative mortality after esophagectomy. Dehiscence of esophageal anastomosis could be fatal, and only high index of suspicion and early diagnosis lead to successful treatment. In majority of such cases conservative measures are successful, however, conduit necrosis is indication for surgical reoperation. Vocal cord palsy due to intraoperative injury of recurrent laryngeal nerves is not rare and increases pulmonary complications rate. New onset of arrhythmia could be associate with other surgical complications. Postesophagectomy chylothorax is life-threatening complication due to rapid development of immunosuppression and septic complications, and early ligation of thoracic duct is often mandatory. Intrathoracic herniation of intrabdominal viscera is rare, and ischemic spinal cord lesions are very rare after esophagectomy. Majority of perioperative complications could be prevented or solved, decreasing mortality rate of esophagectomy.

Intestinal Anastomoses

The safety and effectiveness of a stapled intestinal anastomosis in adults and children is well documented. However, the role of this technique in neonates is not well validated. We report our experience with stapled intestinal anastomoses in the neonate at the University of Mississippi Medical Center. All patients from the neonatal intensive care unit who had a stapled intestinal anastomosis between February 2007 and May 2008 were identified. A stapled side-to-side functional end-to-end intestinal anastomosis was performed in all patients using a gastrointestinal anastomosis stapler. Demographic, management, and outcome data were collected via chart review. Variables collected included: birth weight, estimated gestational age at birth and surgery, weight at surgery, the use of vasopressors, associated diagnoses, location of the anastomosis, and postoperative clinic visits. A total of 18 patients were identified during the study period. Nine had small bowel to small bowel, eight had ileum to colon, and one had a colon to colon anastomosis. The average weight at time of operation was 2.8 kilograms (Kg) and the average estimated gestational age at surgery was 38.7 weeks. The only complication reported was a partial small bowel obstruction on postoperative day 12, which was successfully treated nonoperatively. Two patients died from problems not associated with the anastomosis. There were no anastomotic leaks or strictures. The literature regarding the use of stapled bowel anastomoses in neonates is scant. Stapled intestinal anastomoses can be performed safely in neonates without a high rate of complication. The long term effects of stapled intestinal anastomoses in the neonate are unknown. Future areas of interest would include effects on postoperative feeding and operative time.

BackgroundWe studied patients treated with the EmboTrap revascularization device in a prospective registry which is core laboratory evaluated by physicians from external centers. The goal was to determine how the EmboTrap would perform under the everyday conditions of a high-volume stroke center.MethodsWe examined all patients with acute stroke treated with the Embotrap device from October 2013 to March 2017 in our center. Imaging parameters and times were adjudicated by core laboratory personnel blinded to clinical information, treating physician, and clinical outcomes. Clinical evaluation was performed by independent neurologists and entered in a national registry. Evaluated endpoints were: successful revascularization (modified Thrombolysis in Cerebral Infarction (mTICI) 2b–3) and good clinical outcomes at 3 months (modified Rankin Scale (mRS) 0–2).Results201 consecutive patients with a median NIH Stroke Scale (NIHSS) score of 15 (range 2–30) were included. 170 patients (84.6%) achieved mTICI 2b–3 reperfusion. The median number of attempts was 2 (range 1–10) with 52.8% of the population achieving good functional outcomes (mRS 0–2) at 3 months. On univariate analysis, good functional outcome was associated with the number of attempts, puncture-to-reperfusion time, anterior circulation occlusion, and NIHSS score. On multivariate analysis, pre-treatment NIHSS (OR 0.845 per point, 95% CI 0.793 to 0.908, P<0.001) and puncture-to-reperfusion time (OR 0.9952 per min, 95% CI 0.9914 to 0.9975, P=0.023) were associated with good functional outcomes at 3 months.ConclusionThe Embotrap device has a high rate of successful reperfusion. Our core laboratory-audited single-center experience suggests the technical feasibility and safety of the Embotrap for first-line use in a real-world setting.

Abstract Background Management of cardiovascular implantable electronic devices (CIEDs), including pacemakers and implantable cardioverter defibrillators, for surgical procedures is challenging due to the increasing number of patients with CIEDs and limited availability of trained providers. At the authors’ institution, a small group of anesthesiologists were trained to interrogate CIEDs, devise a management plan, and perform preoperative and postoperative programming and device testing whenever necessary. Methods Patients undergoing surgery between October 1, 2009 and June 30, 2013 at the University of Washington Medical Center were included in a retrospective chart review to determine the number of devices actively managed by the Electrophysiology/Cardiology Service (EPCS) versus the Anesthesiology Device Service (ADS), changes in workload over time, surgical case delays due to device management, and errors and problems encountered in device programming. Results The EPCS managed 254 CIEDs, the ADS managed 548, and 227 by neither service. Over time, the ADS providers managed an increasing percentage of devices with decreasing supervision from the EPCS. Only two CIEDs managed by the ADS required immediate assistance from the EPCS. Patients who were unstable postoperatively were referred to the EPCS. Although numerous issues in programming were encountered, primarily when restoring demand pacing after programming asynchronous pacing for surgery, no patient harm resulted from ADS or EPCS management of CIEDs. Conclusions An ADS can provide safe CIED management for surgery, but it requires specialized provider training and strong support from the EPCS. Due to the complexity of CIED management, an ADS will likely only be feasible in high-volume settings.
