RESUMO
PURPOSE: The Curaçao criteria are well-established diagnostic criteria for hereditary hemorrhagic telangiectasia (HHT), but they lack details regarding a predictive presentation of epistaxis and telangiectasias. This study collects and compares data in HHT and population cohorts to inform the application of these criteria. METHODS: In-person interviews regarding epistaxis and targeted examination for telangiectases in a general population cohort (n = 204) and an HHT cohort (n = 432) were conducted. RESULTS: Frequency of epistaxis, rather than intensity or duration, was the best discriminator of HHT. A cutoff of ≥4 nosebleeds per year alone yielded a diagnostic sensitivity of 97%, and specificity of 84%. The mean number of telangiectases at the sites investigated was 0.4 in the general population cohort and 26.5 in the HHT cohort. The most distinctive sites for telangiectases in HHT were lips and palmar fingers, whereas telangiectases of the face and dorsum of the hand were comparable in both cohorts. CONCLUSION: We propose that the Curaçao criteria be modified to include the following cutoffs: (1) epistaxis frequency of ≥4 nosebleeds per year and (2) telangiectasia count of at least 2 in characteristic locations (palmar aspect of fingers, lips, and oral cavity), and that cutaneous telangiectases at other sites not be considered relevant for diagnostic purposes.

BACKGROUND: Residents commonly use a batched workflow to round on hospitalized patients, creating redundancy and decreasing efficiency. OBJECTIVE: To improve resident efficiency through a novel workflow using mobile laptops and modified rounding-in-flow. DESIGN, SETTING, PARTICIPANTS: A controlled experimental study conducted at an academic medical center for 3 months. One internal medicine team served as the intervention group, and two other teams served as a control group; 34 interns and 20 senior residents participated. INTERVENTION: Residents in the intervention group were provided a novel workflow and a mobile laptop to allow them to round "in-flow." Control group residents rounded as usual (batched workflow without laptops). MAIN MEASURES: Fourteen interns were monitored for a time-motion study. Time-stamped electronic medical record (EMR) data were used to assess percentage of progress notes and orders placed during rounds (9 a.m.-12:30 p.m.) and percentage of discharge summaries signed within 24 h of discharge. A post-intervention survey measured perceived efficiency. RESULTS: A time-motion study showed non-significant differences between time in the intervention group and that in the control group: communication time with patients (128 min vs 105 min, p = 0.37) and computer time (289 min vs 306 min, p = 0.71). EMR data for 664 visits in the control group and 374 in the intervention group showed that rounding-in-flow was associated with an odds ratio (OR) of 1.5 for placing progress notes during rounds (95% CI: 1.2-1.7, p < 0.001), an OR of 1.1 for placing non-discharge orders during rounds (95% CI: 1.0-1.2, p = 0.01), and an OR of 3.9 for signing discharge summaries within 24 h of discharge (95% CI: 2.3-7.2, p < 0.001). Post-intervention survey, completed by 23 of 34 interns, showed that interns in the intervention group perceived that orders were completed during rounds more often than the control group (OR 7.8; 95% CI: 1.3-60.1, p = 0.03). CONCLUSIONS: Using mobile laptops with modified rounding-in-flow was associated with earlier completion of residents' work, suggesting improved efficiency.

Pulmonary arteriovenous malformations (PAVMs) are abnormal connections between the pulmonary artery and pulmonary vein bypassing the normal capillary bed causing a right-to-left shunt. The majority (80-90%) of PAVMs are associated with hereditary hemorrhagic telangiectasia (HHT). PAVMs may be asymptomatic or present with symptoms of hypoxia, shortness of breath, migraines, sequelae of paradoxical embolization, or rupture. Transcatheter embolization has become the standard of care. This article will review the clinical presentation, workup, genetics, imaging findings, embolization, complications, and follow-up for patients with PAVMs.
