RESUMO
OBJECTIVE: To evaluate the hospital charges associated with central venous stenosis in pediatric patients requiring long-term central venous catheters, via associated charges and hospital length of stay (LOS). STUDY DESIGN: This institutional review board-approved retrospective review identified pediatric patients with central venous catheters and either short bowel syndrome (SBS) or end-stage renal disease (ESRD) diagnosed between 2008 and 2015 using the Pediatric Health Information System. These 2 cohorts were selected because long-term central venous access is commonly required for survival. Prevalence of central venous stenosis, total number of admissions, procedures, LOS, and associated charges were recorded. Statistical analysis performed with Wilcoxon nonparametric and 2-sample t test with a significance of P < .05. RESULTS: Of 4952 patients with SBS and 4665 patients with ESRD, 169 (3.4%) patients with SBS and 191 (4.1%) patients with ESRD were diagnosed with central venous stenosis (360 patients total [3.7%]). The cumulative median admissions and LOS was higher in patients with SBS with central venous stenosis (15 admissions and 156 days) vs those without central venous stenosis (5 admissions and 110 days) (P < .001). The cumulative median number of admissions and LOS was higher in patients with ESRD with central venous stenosis (13 admissions and 72 days) vs those without central venous stenosis (7 admissions and 42 days) (P < .001). The mean cumulative charges for patients with SBS with central venous stenosis were higher than for those without central venous stenosis ($1.89 million vs $1.11 million, respectively) (P < .001). Similarly, the mean cumulative charges for patients with ESRD with central venous stenosis were higher than for those without central venous stenosis ($1.17 millions vs $702 000, respectively) (P < .001). CONCLUSIONS: Pediatric patients with central venous stenosis have significantly higher total charges, imaging charges, number of admissions, and longer LOS. Attention to mitigate the incidence of central venous stenosis in pediatric patients requiring long-term central venous access is warranted.

Computer vision syndrome (CVS) is an umbrella term for a pattern of symptoms associated with prolonged digital screen exposure, such as eyestrain, headaches, blurred vision, and dry eyes. Commercially available blue light filtering lenses (BLFL) are advertised as improving CVS. Our pilot study evaluates the effectiveness of BLFL on reducing CVS symptoms and fatigue in a cohort of radiologists. A prospective crossover study was conducted with ten radiology residents randomized into two cohorts: one wearing BLFL first then a sham pair (non-BLFL), and the other wearing a sham pair first then BLFL, over two weeks during normal clinical work. Participants filled out a questionnaire using the validated computer vision syndrome questionnaire (CVS-Q) and the Swedish Occupational Fatigue Inventory (SOFI). The majority of symptoms [11/16 (68.8%) and 13/16 (81.3%) symptoms on the CVS-Q and SOFI, respectively] were reduced (i.e., symptoms less severe) with the BLFL compared to the sham glasses. Females rated symptoms of sleepiness and physical discomfort in the SOFI, and overall CVS-Q, as more severe. Postgraduate year (PGY)-2 residents rated all symptoms as more severe than PGY-3/4s. BLFL may ameliorate CVS symptoms. Future studies with larger sample sizes and participants of different ages are required to verify the potential of BLFL.
RESUMO
PURPOSE: To assess public preferences and perceptions regarding negative chest radiograph reports. METHODS: Using Amazon Mechanical Turk (Amazon Inc, Seattle, Washington), paid US English-speaking volunteers completed an 18-question survey. Participants were presented with the same two chest radiograph reports-one each in a freestyle and structured format-but randomized to one of four impression statements commonly used in our community. Participants were asked about content comprehension and confidence in the hypothetical interpreting radiologist. RESULTS: Over 15 days, 5,155 eligible participants completed the survey (of 6,363 respondents). Most reported prior chest radiography (68.9%) or any imaging (93.8%). Of those who underwent chest radiography, 77.6% reviewed their reports. Participants indicated structured reports were easier to comprehend (P < .001) but no difference in perceived confidence in the radiologist with freestyle versus structured reports (P = .21). No differences in comprehension were noted between different impressions with either freestyle (P = .077) or structured (P = .083) reports. Participants indicated higher confidence in radiologists when structured reports indicated "no acute disease" versus "unremarkable" (P = .049). When impressions stated "no acute disease," participants indicated they would be more likely to do nothing, versus "negative chest" for which they indicated a higher likelihood of taking some action (P = .013, P = .04). Participant responses were similar for subgroups who previously underwent chest or other imaging and previously reviewed their imaging reports. CONCLUSION: For negative chest radiographs, structured reports are better comprehended by the public and less likely to prompt unnecessary follow-up. As patients increasingly access their medical records online, radiologist reporting should consider patient needs and behavior.

PURPOSE: To investigate timing of Yttrium-90 radioembolization (Y90) during treatment course, genomics, and other clinical factors as predictors of overall survival (OS) in colorectal liver metastasis (CRLM) that have progressed on at least one line of chemotherapy. MATERIALS AND METHODS: This was a retrospective study from 2013 to 2018 of patients with CRLM and genomic analysis prior to Y90 at a multihospital tertiary referral center. OS from liver metastasis diagnosis and predictors of OS were analyzed using Kaplan-Meier estimation with log-rank and Cox regression analyses. RESULTS: Overall, 58 patients with CRLM who progressed on at least one line of chemotherapy who had genomic analysis prior to Y90 were identified. Median OS after hepatic metastasis was 29.9 months. Of these, 16 (28%) patients received Y90 after failure of the first-line systemic chemotherapy. There was significantly prolonged OS in patients receiving Y90 immediately following failure of the first-line chemotherapy folinic acid, fluorouracil, oxaliplatin ((FOLFOX) ± bevacizumab) versus following multiple lines of chemotherapy (median OS of 46.3 vs. 26.6 months, P = 0.005). The presence of genetic mutation in tumor, MAPK pathway wild type, left-sided primary tumor, low MELD score, and non-diffuse unilobar disease were also found to be predictors prolonged survival on log-rank analysis (P's < 0.05). On multivariate analysis, receiving Y90 after failure of the first line of chemotherapy, low baseline MELD score, and baseline ECOG performance score of 0 were all found to be independent predictors of prolonged OS from the time of metastatic disease diagnosis (P's < 0.05). CONCLUSION: In patients with CRLM, receiving Y90 after failing the first line of chemotherapy, lack of genetic mutation, low MELD score, and lower tumor burden appear to be independent predictors of prolonged OS. LEVEL OF EVIDENCE: Level 4, case-control study.

STUDY DESIGN: Retrospective review. OBJECTIVE: To ascertain impact of preprocedural magnetic resonance imaging (MRI) or nuclear medicine Tc99m-DMP scintigraphy on the treatment plan when compared with plain films and/or computed tomography prior to vertebral augmentation procedures. SUMMARY OF BACKGROUND DATA: Over 1 million vertebral compression fractures (VCFs) occur in the United States annually with over 150,000 individuals hospitalized each year. Physical examination and history are essential to the workup of VCFs, but imaging remains necessary for confirming the diagnosis. VCFs can be imaged with various modalities and there is limited data on the comparative effectiveness of different imaging modalities. METHODS: Six hundred fifty consecutive patients treated with vertebral augmentation at a single institution between May of 2013 and April of 2018 were reviewed. Preprocedure imaging of the spine obtained within 30 days prior to the procedure were reviewed. Preprocedure imaging results were cross-referenced against the levels treated by vertebral augmentation to determine whether there was a change in the levels treated after receiving an MRI or NM imaging study. RESULTS: Three hundred sixty-three patients had adequate imaging for inclusion. One hundred fifty-four of these 363 patients (42.4%) had an alteration of their treatment plan based upon the MR or NM imaging. Fewer vertebral levels were treated in 33, different levels were treated in 41, and more levels were treated in 80 patients. CONCLUSION: MRI or nuclear medicine bone scan imaging prior to vertebral augmentation altered the location and number of levels treated in a large percentage of patients, adding specificity to treatment over findings on radiographs or computed tomography alone. LEVEL OF EVIDENCE: 3.

A gravida 4 para 1021, 41-year-old woman postcaesarean section at 39 weeks and 1 day with clinically significant haemorrhage required embolisation of unique uterine arterial collaterals. She had persistent haemorrhage after initial bilateral uterine artery embolisation, and on further investigation she was found to have a hypertrophied right round ligament artery. Once successful embolisation of this abnormal right round ligament artery was completed using a combination of Gelfoam and coils, haemostasis was achieved. She had rapid clinical improvement, no complications and no further admissions on postprocedural follow-up over a year and a half later.

OBJECTIVE: Lung shunt fraction studies using technetium-99 m macro aggregated albumin are routinely performed before yttrium-90 radioembolization regardless of underlying liver malignancy type. This study evaluates the role of lung shunt fraction studies in hepatocellular carcinoma compared to non-hepatocellular carcinoma liver tumors. METHODS: A single-institution retrospective analysis of all pre-yttrium-90 technetium-99 m macro aggregated albumin lung shunt fraction studies between November 2012 to March 2018 was performed. Patient variables including age, underlying malignancy, laboratory values, lung shunt fraction, and severity of liver disease were compared between hepatocellular carcinoma and non-hepatocellular carcinoma cases. RESULTS: A total of 734 technetium-99 m macro aggregated albumin studies were identified in 653 patients. Among these cases, the liver tumor was hepatocellular carcinoma in 368 (50.1%), colorectal cancer in 112 (15.3%), neuroendocrine tumor in 89 (12.1%), cholangiocarcinoma in 59 (8.0%), breast cancer in 27 (3.7%), and other metastatic malignancies in 79 (10.7%). The mean lung shunt fraction for non-hepatocellular carcinoma cases was 7.4%, which was significantly lower than the mean lung shunt fraction, 11.7%, for hepatocellular carcinoma cases (P = 0.0001). In only one non-hepatocellular carcinoma case was yttrium-90 radioembolization not pursued due to high lung shunt fraction (69.3%), wherein large scale shunting was grossly apparent on angiography in a patient with metastatic gastrointestinal stromal tumor. In comparison, the lung shunt fraction was too high to pursue radioembolization in 37 hepatocellular carcinoma cases (mean lung shunt fraction 35.1%). CONCLUSION: Lung shunt fraction appears low among patients with non-hepatocellular carcinoma liver malignancies. Further analysis examining the necessity of pre-Y90 technetium-99 m macro aggregated albumin lung shunt fraction studies in patients with non-hepatocellular carcinoma malignancies is warranted, since a consolidated yttrium-90 radioembolization without prior lung shunt fraction evaluation could reduce resource consumption, improve workflows, and patient access.
