SummaryBackgroundDuodenal injury persists in some coeliac disease patients despite gluten‐free diet, and is associated with adverse outcomes.AimTo determine the prevalence and clinical risk factors for persistent villus atrophy among symptomatic coeliac disease patients.MethodsA nested cross‐sectional analysis was performed on coeliac disease patients with self‐reported moderate or severe symptoms while following a gluten‐free diet, who underwent protocol‐mandated duodenal biopsy upon enrolment in the CeliAction clinical trial. Demographic factors, symptom type, medication use, and serology were examined to determine predictors of persistent villus atrophy.ResultsOf 1345 symptomatic patients, 511 (38%, 95% CI, 35–41%) were found to have active coeliac disease with persistent villus atrophy, defined as average villus height to crypt depth ratio ≤2.0. On multivariable analysis, older age (OR, 5.1 for ≥70 vs. 18–29 years, 95% CI, 2.5–10.4) was a risk factor while longer duration on gluten‐free diet was protective (OR, 0.37, 95% CI, 0.24–0.55 for 4–5.9 vs. 1–1.9 years). Villus atrophy was associated with use of proton‐pump inhibitors (PPIs; OR, 1.6, 95% CI, 1.1–2.3), non‐steroidal anti‐inflammatory drugs (NSAIDs; OR, 1.64, 95% CI, 1.2–2.2), and selective serotonin reuptake inhibitors (SSRIs; OR, 1.74, 95% CI, 1.2–2.5). Symptoms were not associated with villus atrophy after adjusting for covariates.ConclusionsA majority of symptomatic coeliac disease patients did not have active disease on follow‐up histology. Symptoms were poorly predictive of persistent mucosal injury. The impact of NSAIDs, PPIs, and SSRIs on mucosal healing in coeliac disease warrants further study.

Background: Therapy programs to treat thumb carpometacarpal (CMC) arthritis may engage selective activation and reeducation of thenar muscles, particularly the first dorsal interosseous (FDI) and opponens pollicis (OP) to reduce subluxation of the joint. We describe the effect of simulated selective activation of the FDI and OP muscles upon radiographic subluxation of the thumb CMC joint. Methods: In a cadaver model of CMC subluxation, loads were applied to the FDI, the OP, and then concomitantly at 0%, 25%, 50%, 75%, and 100% maximal loads and radial subluxation of the joint and reduction in subluxation was measured. Results: Selective activation of the OP, alone, improved the subluxation ratio (SR) in a dose-dependent manner. Selective activation of FDI, alone, demonstrated minimal effects on SR. Concomitant activation of OP and FDI improved the SR across all loading states, and activation of 75% and greater, when compared with FDI activation alone, resulted in a statistically significant improvement in SR to within 10% of the presubluxed joint. Conclusions: Concomitant activation of the FDI and OP acts to reduce subluxation of the thumb CMC joint in a dose-dependent fashion. The OP is likely the predominant reducing force. Hand therapy programs that focus on selective strengthening programs likely function in part to encourage patients to activate the easily palpable and easily understood FDI. Concomitant coactivation of the OP may be the major reducing force to elicit clinical and radiographic reduction of subluxation, improved thumb positioning, and reduction of pain and arthritic symptoms.

BackgroundSyncope is a common reason for outpatient transthoracic echocardiography (TTE). We studied the applicability of pediatric appropriate use criteria (AUC) on initial outpatient evaluation of children (≤18 years) with syncope.MethodsData were obtained before (Phase I, April–September 2014) and after (Phase II, January‐April 2015) the release of the AUC document from six participating pediatric cardiology centers. Site investigators determined the indication for TTE and assigned appropriateness rating based on the AUC document: Appropriate (A), May Be Appropriate (M), Rarely Appropriate (R), or “unclassifiable” (U) if it did not fit any scenario in the AUC document.ResultsOf the total 4562 TTEs, 310 (6.8%) were performed for syncope: 174/2655 (6.6%) Phase I and 136/1907 (7.1%) Phase II, P=.44. Overall, 168 (50.5%) were for indications rated A, 63 (18.9%) for M, 79 (23.7%) for R, and 23 (6.9%) for U. Release of AUC did not change the appropriateness of TTEs [A=51.6% vs 49.0%, P=.63, R=20.2% vs 28.3%, P=.09]. Overall syncope‐related R indications formed 15.7% of R indications for all the echocardiograms performed in the entire Pediatric Appropriate Use (PAUSE) study (11.9% Phase I and 22.4% Phase II, P=.002). TTEs were normal in majority of the patients except 7 that had incidental findings.ConclusionsIn conclusion, syncope is a common reason for indications rated R and release of the AUC document did not improve appropriate utilization of TTE in syncope. Targeted educational interventions are needed to reduce unnecessary TTEs in children with syncope.

Purpose: We sought to assess for impact on management trends in new patients presenting to our institution with stress urinary incontinence (SUI) following the release of the FDA Health Notification in July 2011 for vaginal mesh. Materials and methods: Chart analysis was performed on patients assigned a primary International Classification of Diseases (ICD-9) diagnosis code of 625.6 for SUI at initial consultation by two providers at our institution between June 1, 2010 and November 30, 2014. Rates of treatment and types of procedures performed were analyzed: urethral bulking, mesh sling, or pubovaginal sling. Results: A total of 333 new patients were identified with an increasing trend over time. One hundred and twenty-three patients underwent 153 procedures for stress incontinence. The mean proportion that had a procedure per six-month period was 37%, with decreasing proportions over time. Initially all procedures were midurethral mesh slings, with a decline at the time of and after the notification, and a temporary increase in bulking procedures. Subsequently, there was a rise again in sling placement, namely with an increase in pubovaginal slings. Of the 20 pubovaginal slings placed, 13 were placed in patients who had a prior anti-incontinence surgery (eight for sling failure, vaginal mesh, or fixed urethra, and two in patients with mesh extrusion/erosion). Seven were performed in patients who had never had prior surgery (two for very high-grade incontinence, two with urethral diverticulectomy, and three in patients who expressed concern about mesh). Conclusions: Although there were an increasing number of patients seen for management of SUI over time, there was a progressive decrease in the proportion of patients having anti-incontinence procedures after release of the FDA notification. There was an overall decrease in the use of mesh slings and an increase in bulking, and more notably, placement of pubovaginal slings.

Background: Quantitative magnetic resonance (qMR) can be used to measure macromolecules in tissues and is a potential method of observing early cartilage changes in the development of posttraumatic osteoarthritis. Hypothesis/Purpose: We hypothesized that specific patient and surgical factors affecting cartilage matrix composition after anterior cruciate ligament (ACL) reconstruction (ACLR) can be detected using T1ρ and T2 relaxation times. Our purpose was to demonstrate this ability in a multicenter feasibility study. Study Design: Case series; Level of evidence, 4. Methods: A total of 54 patients who underwent ACLR underwent bilateral MRI at baseline before surgery and 6 months postoperatively. Operative findings were recorded. T1ρ and T2 relaxation times were calculated for 6 cartilage regions: the medial femur, lateral femur, medial tibia, lateral tibia, patella, and trochlea. A paired t test compared relaxation times at baseline and 6 months, univariate regression identified regions that influenced patient-reported outcome measures, and analysis of covariance was used to determine the surgical factors that resulted in elevated relaxation times at 6 months. Results: The injured knee had significantly prolonged T1ρ and T2 relaxation times in the tibiofemoral compartment at baseline and 6 months but had shorter values in the patellofemoral compartment compared with the uninjured knee. Prolonged T1ρ and T2 times at 6 months were noted for both the injured and uninjured knees. At 6 months, prolongation of T1ρ and T2 times in the tibial region was associated with lower patient-reported outcome measures. ACLR performed within 30 days of injury had significantly shorter T1ρ times in the tibial regions, and lateral meniscal tears treated with repair had significantly shorter T1ρ times than those treated with excision. Conclusion: Prolonged relaxation times in multiple regions demonstrate how the injury affects the entire joint after an ACL tear. Changes observed in the uninjured knee may be caused by increased loading during rehabilitation, especially in the patellofemoral articular cartilage and distal femur. Relaxation times in the tibial regions may be predictive of patient symptoms at 6 months. These same regions are affected by surgical timing as early as 30 days after injury, but this may partially be reflective of the severity of the preoperative injury and the choice of treatment of meniscal tears.

Objectives Rectovaginal fistulae (RVF) often represent surgical challenges, and treatment must be individualized. We describe outcomes after primary surgical repair stratified by fistula etiology and surgical approach. Methods This retrospective cohort study included women who underwent surgical management of RVF at a tertiary care center between July 1, 2001 and December 31, 2013. Cases were stratified according to the following etiology: cancer (RVF-C), inflammatory bowel disease or infectious (RVF-I), and other (RVF-O). Patients with prior surgical treatment of RVF were excluded. Surgical approaches included local (seton, plug), transvaginal or endorectal, abdominal, diversion alone, or definitive (completion proctocolectomy with permanent colostomy or pelvic exenteration). Recurrence-free survival was estimated using the Kaplan-Meier method, and comparisons between subgroups were evaluated based on fitting Cox proportional hazards models. Censoring occurred at last relevant clinical follow-up. Factors contributing to recurrence-free survival were evaluated including age, body mass index, smoking status, fistula etiology, ileostomy, and surgical approach. Results During the study period, 107 women underwent surgical repair of RVF. The most common fistula etiology was RVF-I (54.2%), followed by RVF-O (23.4%), and RVF-C (22.4%). Ninety-four women underwent fistula repair by the local (29.9%), transvaginal/endorectal (25.2%), abdominal approach (19.6%), or diversion alone (13.1%), whereas 13 underwent definitive surgery (12.2%). Recurrence-free survival was significantly different depending on surgical approach ( P < 0.001), but not etiology ( P = 0.71). Recurrence-free survival (95% confidence interval) at 1 year after surgery was 35.2% (21.8%–56.9%) for the local approach, 55.6% (37.0%–83.3%) for the transvaginal or endorectal approach, 95% (85.9%–100%) for the abdominal approach, and 33.3% (15%–74.2%) for those with diversion only. Conclusions Recurrence rates after RVF repair are high and did not differ by fistula etiology. Abdominal repair of RVF had significantly fewer recurrences.
