| 1 | Two-point compression ultrasonography: Enough to rule out lower extremity deep venous thrombosis?显示文摘BACKGROUND: Deep venous thrombosis(DVT) is a major cause of morbidity and is a common presenting complaint to the emergency department(ED). Point-of-care two-point compression ultrasonography has evolved as a quick and effective way of diagnosing DVT. The purpose of this study is to validate the prevalence and distribution of venous thrombi isolated to proximal lower extremity veins, other than common femoral and popliteal veins in patients with DVT.METHODS: This is a single-center retrospective study that looked at patients presenting to the ED of a tertiary care hospital between January 2014 and August 2018. The clinical presentation and laboratory and imaging results were obtained using the hospital's electronic medical record.RESULTS: A total of 2,507 patients underwent a lower extremity duplex ultrasound during the study period. Among them, 379(15%) were included in the study. The percentages of isolated thrombi to the femoral vein and deep femoral vein were 7.92% and 0.53%, respectively. When the patients were stratified into the two groups of isolated DVT and two-point compression DVT, there were no statistically significant differences in the laboratory results between both groups. However, immobilized patients and patients with recent surgeries were more likely to have an isolated DVT.CONCLUSIONS: Thrombi isolated to proximal lower extremity veins other than the common femoral and popliteal veins make up 8.45% of DVTs. Given this significant number of missed DVTs, the authors recommend the addition of the femoral and deep femoral veins to the two-point compression exam. | Ralphe Bou Chebl Nader El Souki Mirabelle Geha Imad Majzoub Rima Kaddoura Hady Zgheib | 2021 | World Journal of Emergency Medicine2021，12，4： | 2 |

| 4 | Sensory characterization of bowel cleansing solutions显示文摘AIM: To evaluate the sensory characteristics of commercial bowel cleansing preparations.METHODS: Samples of 4 commercially available bowel cleansing preparations, namely polyethylene glycol electrolyte solution(PEG), PEG + ascorbic acid(PEG-Asc), sodium picosulfate(SPS), and oral sodium sulfate(OSS) were prepared according to the manufacturer's instructions. Descriptive analysis was conducted(n = 14) using a 15-cm line scale with the Compusense at-hand? sensory evaluation software. Acceptability testing(n = 80) was conducted using the 9-point hedonic scale. In addition, a Just-About-Right(JAR) scale was included for the four basic tastes to determine their intensity compatibility with acceptability levels in the products.RESULTS: Samples were significantly different, in descriptive analysis, for all attributes(P < 0.05) except for sweetness. SPS received the highest ratings for turbidity, viscosity appearance, orange odor and orange flavor; PEG-Asc for citrus odor and citrus flavor; OSS for sweetener taste, sweet aftertaste, bitterness, astringency, mouthcoating, bitter aftertaste and throatburn, and along with PEG-Asc, the highest ratings for saltiness, sourness and adhesiveness. Acceptability results showedsignificant differences between the various samples(P < 0.05). SPS received significantly higher ratings for overall acceptability, acceptability of taste, odor and mouthfeel(P < 0.05). JAR ratings showed that PEG and PEG-Asc were perceived as slightly too salty; SPS and OSS were slightly too sweet, while SPS, PEG-Asc and OSS were slightly too sour and OSS slightly too bitter. While using small sample volumes was necessary to avoid unwanted purgative effects, acceptability ratings do not reflect the true effect of large volumes intake thus limiting the generalization of the results.CONCLUSION: Further improvements are needed to enhance the sensory profile and to optimize the acceptability for better compliance with these bowel cleansing solutions. | Ala I Sharara Hamza Daroub Camille Georges Rani Shayto Ralph Nader Jean Chalhoub Ammar Olabi | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，15： | 1 |

| 7 | Role of urine studies in asymptomatic febrile neutropenic patients presenting to the emergency department显示文摘BACKGROUND: The role of urine studies in the detection of urinary tract infection(UTI) in febrile neutropenic patients with urinary symptoms(having a urinary catheter or having a positive urine analysis) is inarguable. However, the evidence is scarce regarding the indication for urine studies in asymptomatic(i.e., without urinary symptoms) patients with febrile neutropenia(FN) presenting to the emergency department(ED). The aim of this study is to evaluate the need for obtaining urine studies in asymptomatic febrile neutropenic patients.METHODS: This was a retrospective cohort study conducted on adult cancer patients who presented to the ED with FN and had no urinary symptoms. We included all ED presentations of eligible patients between January 2013 and September 2018. Student's t-test and Wilcoxon rank-sum test were used for continuous data, while Chi-square and Fisher's exact tests were used for categorical data. Participants were divided into two groups based on their urine culture(UC) results: negative and positive UCs. Two cut-offs were used for positive UC results: ≥10~5 cfu/m L and ≥10~4 cfu/m L.RESULTS: We included 284 patients in our study. The age of our patient population was 48.5±18.5 years. More than two-thirds(68.7%) of patients had severe neutropenia, while only 3.9% and 9.9% of the patients had positive UCs at ≥10~5 cfu/m L and ≥10~4 cfu/m L, respectively. UCs were expectedly positive in most patients with urinalysis(UA) abnormalities. However, 27.3% and 32.1% of patients with positive UCs at ≥10~5 cfu/m L and ≥10~4 cfu/m L respectively had a normal UA. CONCLUSIONS: In our study, the incidence of UTI in adult febrile neutropenic cancer patients who present to the ED without urinary symptoms is low. Consequently, routine urine testing may not be warranted in this population, as it adds unnecessary financial burdens on the patients and delays timely management. | Hady Zgheib Aline El Zakhem Cynthia Wakil Mohamad Ali Cheaito Rola Cheaito Antoine Finianos Ralphe Bou Chebl Rima Kaddoura Nader Al Souky Imad El Majzoub | 2021 | World Journal of Emergency Medicine2021，12，2： | 0 |
