Xanthomas within the gastrointestinal tract occur secondary to a mucosal insult. When enough cells accumulate, their appearance can range from small nodules studding the intestinal mucosa to bandlike infiltrations to pseudotumor-like masses within the intestine with fibrosis and inflammation resembling malignancy. When large enough, they can produce symptoms of obstruction such as vomiting, abdominal pain, distention, and dysmotility. This case demonstrates the epidemiology, clinical presentation, diagnosis, and treatment of duodenal xanthomas.

OBJECTIVES/OBJECTIVE:We explored patient perceptions regarding physician attire in different clinical contexts and resultant effects on the physician-patient relationship. SETTING/METHODS:The 900-bed University Hospital Zurich, Switzerland. PARTICIPANTS/METHODS:A convenience sample of patients receiving care in dermatology, infectious diseases and neurology ambulatory clinics of the University Hospital Zurich participated in a paper-based survey. PRIMARY AND SECONDARY OUTCOME MEASURES/UNASSIGNED:The survey instrument was randomised and showed photographs of male or female physicians wearing various forms of attire. On the basis of the respondents' ratings of how the physician's attire affected perceptions across five domains (knowledgeable, trustworthy, caring, approachable and comfort with the physician), a composite preference score for attire was calculated as the primary outcome. Secondary outcomes included variation in preferences by respondent characteristics and context in which care was provided. RESULTS:Of 834 patient respondents (140 in dermatology, 422 in infectious diseases and 272 in neurology), 298 (36%) agreed that physician attire was important. When compared with all available choices, the combination of white scrubs with white coat was rated highest while a business suit ranked lowest. Variation in preferences and opinions for attire were noted relative to respondent demographics and the clinical setting in which the survey was administered. For example, compared with younger patients, respondents ≥65 years of age more often reported that physician dress was both important to them and influenced how happy they were with their care (p=0.047 and p=0.001, respectively). CONCLUSIONS:Outpatients at a large Swiss University hospital prefer their physicians to be dressed in white scrubs with white coat. Substantial variation among respondents based on demographics, type of physician and clinical setting were observed. Healthcare systems should consider context of care when defining policies related to dress code.

Background It is uncertain whether there is an association between left ventricular (LV) ejection fraction ( LVEF ) or LV wall motion abnormality and embolic stroke of undetermined source ( ESUS ). Methods and Results We performed a retrospective, cross-sectional study of patients with acute ischemic stroke enrolled in the CAESAR (Cornell Acute Stroke Academic Registry) from 2011 to 2016. We restricted this study to patients with ESUS and, as controls, those with small- and large-artery ischemic strokes. LVEF had to be above 35% to be considered ESUS . In a secondary analysis, we excluded patients with ESUS who had any evidence of ipsilateral carotid atherosclerosis. Multiple logistic regression was used to evaluate whether LVEF or LV wall motion abnormality was associated with ESUS . We performed a confirmatory study at another tertiary-care center. We identified 885 patients with ESUS (n=503) or small- or large-artery strokes (n=382). Among the entire cohort, LVEF was not associated with ESUS (odds ratio per 5% decrement in LVEF , 1.0; 95% CI, 1.0-1.1) and LV wall motion abnormality was not associated with ESUS (odds ratio, 0.9; 95% CI, 0.5-1.6). The results were identical in our confirmatory study. In our secondary analysis excluding ESUS patients with any evidence of ipsilateral carotid atherosclerosis, there was an association between LVEF and ESUS (odds ratio per 5% decrement in LVEF , 1.2; 95% CI, 1.0-1.5; P=0.04). Conclusions Among the entire cohort, no association existed between LVEF or LV wall motion abnormality and ESUS ; however, after excluding ESUS patients with any evidence of ipsilateral carotid atherosclerosis, lower LVEF appeared to be associated with ESUS .

In this needs assessment, gathered patient perceptions on how telemedicine video visits might influence their care. Patients in this study (n = 13) were all diagnosed with end-stage cancer and were receiving palliative care at an urban academic medical center. Interview themes addressed: 1. impact on patient's health management, 2. user experience, 3. technical issues and 4. cost and time. Ultimately, despite concerns over truncated physical exams and prescription limits, the majority of patients favored having the opportunity for telemedicine video visits, felt that the doctor-patient relationship would not suffer, had confidence in their or their surrogate's technical abilities to navigate the video visit, had privacy concerns on par with other technologies, had few cost concerns, and believed a video alternative to an in-person visit might increase access, save time as well as increase comfort and safety by avoiding a trip to the office. These results suggest potential for acceptance of video-based telemedicine by an urban population of oncology patients receiving palliative care.

Despite modern investigative innovations in the cutting edge field of gastroenterology, we are reminded of our contemporary limitations when we encounter the ever evasive Dieulafoy's lesion (DL). Ever since it has been initially described in 1884, its rare but frustrating presence creates a calamitous situation. Even more so when it presents atypically, much like it did in our patient. This review of DL delves into the history, epidemiology, characteristics, the most current and innovative diagnostic measures available, as well as treatment and prevention of recurrence of these obscure gastrointestinal (GI) bleeding sources.

BACKGROUND:Complementary and alternative medicines (CAM) are associated with poor asthma medication adherence, a major risk factor for asthma exacerbation. However, previous studies showed inconsistent relationships between CAM use and asthma control due to small sample sizes, demographic differences across populations studied, and poor differentiation of CAM types. METHODS:We examined associations between CAM use and asthma exacerbation using a cross-sectional analysis of the 2012 National Health Interview Survey. We included adults ≥18 years with current asthma (n = 2,736) to analyze racial/ethnic differences in CAM use as well as the association between CAM use and both asthma exacerbation and emergency department (ED) visit for asthma exacerbation across racial/ethnic groups. We ran descriptive statistics and multivariable logistic regressions. RESULT/RESULTS:Blacks (OR = 0.63 [0.49-0.81]) and Hispanics (OR = 0.66 [0.48-0.92]) had decreased odds of using CAM compared to Whites. Overall, there was no association between CAM use and asthma exacerbation (OR = 0.99 [0.79-1.25]) but the subgroup of 'other complementary approaches' was associated with increased odds of asthma exacerbation among all survey respondents (1.90 [1.21-2.97]), Whites (OR = 1.90 [1.21-2.97]), and Hispanics (OR = 1.43 [0.98-2.09). CAM use was associated with decreased odds of an ED visit for asthma exacerbation (OR = 0.65 [0.45-0.93]). These associations were different among racial/ethnic groups with decreased odds of ED visit among Whites (OR = 0.50 [0.32-0.78]) but no association among Blacks and Hispanics. CONCLUSION/CONCLUSIONS:We found that both CAM use and the association between CAM use and asthma exacerbation varied by racial/ethnic group. The different relationship may arise from how CAM is used to complement or to substitute for conventional asthma management.

Introduction Adrenocortical carcinoma (ACC) is a rare cancer that commonly spreads to the liver, lungs and lymph nodes. Bone metastases are infrequent. Objective The aim of this report was to describe the clinical characteristics, survival perspective, prognostic factors and frequency of adverse skeletal-related events (SREs) in patients with ACC who developed bone metastasis. Methods This is a retrospective, observational, multicenter, multinational study of patients diagnosed with bone metastases from ACC who were treated and followed up in three European countries (France, Italy and The Netherlands) and one center in the United States. Results Data of 156 patients were captured. The median overall survival was 11 months. SREs occurred in 47% of patients: 17% bone fractures, 17% spinal cord compression, 1% hypercalcemia, 12% developed more than one SRE. In multivariate analysis, cortisol hypersecretion was the only prognostic factor significantly associated with a higher mortality risk (hazard ratio (HR) 2.24, 95% confidence interval (CI): 1.19-4.23, P = 0.013) and with the development of a SREs (of border line significance). The administration of antiresorptive therapies (bisphosphonates and denosumab) was associated with a lower risk of death, even if not significant, and their survival benefit appeared confined in patients attaining serum mitotane levels within the therapeutic range. Conclusion Bone metastases in ACC patients are associated with poor prognosis and high risk of SREs. Cortisol hypersecretion was the only prognostic factor suggesting a potential benefit from antisecretory medications. The therapeutic role of bisphosphonates and denosumab to improve patient outcome deserves to be tested in a prospective clinical trial.
