Background:This study aimed to assess the accuracy of three-point compression ultrasonography (3PCUS) performed for the diagnosis of proximal deep-vein thrombosis (DVT) in Emergency Department (ED) compared with the results of duplex US (DUS) (whole-leg compression ultrasound).Materials and Methods:The current prospective cross-sectional study with diagnostic test assessment was conducted on adult patients who were referred to the ED of a general teaching hospital in Shiraz, southern part of Iran (September 2016–May 2017), suspected of lower-extremity DVT, using a convenience sampling. The results of 3PCUS performed by ED residents were compared with the results of DUS performed by the radiology residents, which was considered as a criterion standard.Results:A total of 240 patients were enrolled, with a mean (standard deviation) age of 59.46 (16.58). 3PCUS has a sensitivity and a specificity of 100% (95% confidence interval [CI], 96.55%–100%) and 93.33% (95% CI, 87.72%–96.91%), respectively, in comparison with DUS (whole-leg compression ultrasound). Negative predictive value and positive predictive value were 100% and 92.11% (95% CI, 86.12%–95.64%), respectively, with an accuracy of 96.25% (95% CI, 93%–98.27%).Conclusion:The results of this study showed that 3PCUS of the lower extremities with a portable US machine, performed by the ED's residents, can accurately identify the presence or absence of lower-extremity DVT.
Introduction: One of the largest religious gatherings in the world is the Arbaeen pilgrimage, which takes place on the 40th day after the anniversary of the martyrdom of Imam Hussein, the third Shiite Imam. This study was aimed to investigate how to set up the Sahib-al-Zaman treatment camp on the Arbaeen walking route in 2019 and the patients referring to it. Methods: This retrospective cross-sectional study was conducted on all patients referring to the Sahib-al-Zaman camp of Shiraz University of Medical Sciences, Shiraz, Iran in the Arbaeen Walking plan in 2019. In this study, how to set up camp was described. Patients’ data and drugs used by the medical team were collected, and then were analyzed. Results: Totally, 3477 patients were enrolled. The mean±SD of patients’ age was 33.77±16.19 (ranging from 1 to 96) years, and 2,183 patients (62.78%) were male. Most patients were Iranian (84.5%) and then Iraqi (13.66%), and only 1.84% were from other nationalities. Upper respiratory tract infection (60.2%), low back pain and muscle cramps (17.6%), and blister and need for dressing (12.3%) were the most common chief complaints in the patients. Adult cold pills, acetaminophen (325 mg), and cetirizine (10 mg) were the most commonly prescribed drugs for the patients. Conclusion: Although the data used in this study are not sufficient due to the lack of a pre-created data recording system, the results of this study showed that in addition to the importance and necessity of holding such ceremonies, health issues and facilities should also be considered.
Diagnostic and therapeutic interventions in children for traumatic brain injury, which is known as the most important complication in trauma, require special attention. This study aimed to evaluate the accuracy of point-of-care ultrasound (POCUS) in diagnosing skull fracture in children with closed head injury in comparison with computed tomography (CT) scan. The current prospective cross-sectional study was conducted on children (0–14 years old), who were referred to the emergency department of a general teaching hospital in Shiraz, southern Iran (January–March 2018), with close head injury and were suspected of bone fracture. The participants were selected using a convenience sampling. The results of POCUS performed by emergency medicine (EM) residents were compared with the results of CT scan, which was reported by radiologists and considered a gold standard. Then, diagnostic tests were calculated. A total of 168 children were enrolled, with the mean ± standard deviation age of 6.21 ± 3.99. The most affected areas in the skull were the frontal (34.5%) and occipital areas (33.3%). POCUS had a sensitivity and specificity of 81.8% (95%CI, 48.2–97.7%) and 100% (95%CI, 97.7–100%), respectively. Positive and negative predictive values were 100% and 98.7%, with an accuracy of 98.8% in comparison with CT scan in the diagnosis of skull fracture. Conclusion : The results showed that POCUS with a portable ultrasonography machine, performed by the EM’s physicians, have high diagnostic precision and can be considered a tool in the management of patients with closed head injury. What is Known: • Some studies have investigated the accuracy of ultrasound in diagnosing skull bone fractures in children with closed head injury, but before conducting this survey, no definite evidence recommended POCUS for skull fracture in children with closed head trauma in the ED. What is New: • POCUS with a portable ultrasonography machine, performed by the EM’s physicians, has high diagnostic precision and can be considered a tool in the management of patients with closed head injury.
