Vascular anomalies encompass a spectrum of tumors and malformations that can cause significant morbidity and mortality in children and adults. Use of the International Society for the Study of Vascular Anomalies (ISSVA) classification system is strongly recommended for consistency. Vascular anomalies can occur in isolation or in association with clinical syndromes that involve complex multifocal lesions affecting different organ systems. Thus, it is critical to be familiar with the differences and similarities among vascular anomalies to guide selection of the appropriate imaging studies and possible interventions. Syndromes associated with simple vascular malformations include hereditary hemorrhagic telangiectasia, blue rubber bleb nevus syndrome, Gorham-Stout disease, and primary lymphedema. Syndromes categorized as vascular malformations associated with other anomalies include Klippel-Trenaunay-Weber syndrome, Parkes Weber syndrome, Servelle-Martorell syndrome, Maffucci syndrome, macrocephaly-capillary malformation, CLOVES (

There is little evidence supporting the use of a water-soluble contrast challenge (WSCC) for conservative management of nonadhesive small bowel obstruction (NASBO). Our objective was to evaluate the prognostic value of the WSCC in a diverse group of patients with NASBO in comparison with patients with adhesive small bowel obstruction (ASBO).Retrospective chart review of patients with ASBO or NASBO who underwent a WSCC during a 4-year time period was performed. The primary study endpoint was any intervention for small bowel obstruction during the initial admission or within 30 days of discharge.A total of 106 patients were included, 53 with ASBO (mean age 64 ± 13 years [SD]; 55% women) and 53 with NASBO (mean age 59 ± 13 years [SD]; 57% women). A higher rate of interventions during admission or within 30 days of discharge was seen in patients with NASBO compared with ASBO (24/53 [45%] vs 12/53 [23%]; p = 0.01), including those with colonic transit times of less than 36 hours (14/41 [34%] vs 5/43 [12%]; p = 0.01). Using multivariate analysis, transit time greater than 36 hours remained an independent predictor of an intervention during admission or within 30 days of discharge (p0.001, odds ratio 19.0), after controlling for the type of small bowel obstruction.A majority of patients with NASBO were successfully managed conservatively during a 30-day period, supporting the use of WSCC in patients with NASBO; however, patients with NASBO had a higher rate of interventions during admission or within 30 days of discharge.

Rationale & Objective Although maintaining high fluid intake is an effective low-risk intervention for the secondary prevention of urinary stone disease, many patients with stones do not increase their fluid intake. Study Design We describe the rationale and design of the Prevention of Urinary Stones With Hydration (PUSH) Study, a randomized trial of a multicomponent behavioral intervention program to increase and maintain high fluid intake. Participants are randomly assigned (1:1 ratio) to the intervention or control arm. The target sample size is 1,642 participants. Setting & Participants Adults and adolescents 12 years and older with a symptomatic stone history and low urine volume are eligible. Exclusion criteria include infectious or monogenic causes of urinary stone disease and comorbid conditions precluding increased fluid intake. Interventions All participants receive usual care and a smart water bottle with smartphone application. Participants in the intervention arm receive a fluid intake prescription and an adaptive program of behavioral interventions, including financial incentives, structured problem solving, and other automated adherence interventions. Control arm participants receive guideline-based fluid instructions. Outcomes The primary end point is recurrence of a symptomatic stone during 24 months of follow-up. Secondary end points include changes in radiographic stone burden, 24-hour urine output, and urinary symptoms. Limitations Periodic 24-hour urine volumes may not fully reflect daily behavior. Conclusions With its highly novel features, the PUSH Study will address an important health care problem. Funding National Institute of Diabetes and Digestive and Kidney Diseases.

The purpose of this study is to quantify the clinical impact of resident-attending discrepancies at a tertiary referral academic radiology residency program by assessing rates of intervention, discrepancy confirmation, recall rate, and management change rate; furthermore, a discrepancy categorization system will be assessed.Retrospective review of the records was performed for n = 1482 discrepancies that occurred in the 17-month study period to assess the clinical impact of discrepancies. Discrepancies were grouped according to a previously published classification system. Management changes were recorded and grouped by severity. The recall rate was estimated for discharged patients. Any confirmatory testing was reviewed to evaluate the accuracy of the discrepant report. Categorical variables were compared to the chi-square test.The 1482 discrepancies led to management change in 661 cases (44.6%). The most common management change was follow-up imaging. Procedural interventions including surgery occurred in 50 cases (3.3%). The recall rate was 2.6%. Management changes were more severe with computed tomography examinations, inpatients, and when the discrepancy was in the chest and abdomen subspecialty. Also, management changes correlated with the discrepancy category assigned by the attending at the time of review.Resident-attending discrepancies do cause management changes in 44.6% of discrepancies (0.62% overall); the most frequent change is follow-up imaging. The discrepancy categorization assigned by the attending correlated with the severity of management change.
