Bedside ultrasonography (BUS) has been widely used in many emergency evaluations, but the technique was not thoroughly evaluated for use in adult fractures. The water bath technique (WBT) is a modality which overcomes some important limitations of using BUS in extremity fractures. The study aims to evaluate and compare diagnostic values of BUS and WBT. The sensitivity, specificity, positive and negative predictive values (PPV and NPV), positive and negative likelihood ratios (LR+ and LR-), and accuracy of BUS and WBT were calculated and compared by the McNemar chi-square test. BUS had the highest sensitivity, specificity, PPV, and LR+ in the distal forearm. The highest NPV and LR- of BUS were seen in phalangeal and wrist injuries, respectively. The WBT examination had the highest sensitivity in phalangeal injuries and the highest specificity, PPV, and LR+ in the distal forearm. The highest NPV and LR- of the WBT examination were seen in phalangeal and wrist injuries, respectively. The McNemar χ (2) values for the comparison of BUS and WBT indicate that the two techniques provide statistically different results. The ultrasound revealed excellent diagnostic values which make it a favorable alternative in evaluating upper extremity fractures in adults. The WBT provides even better results.
Introduction. Citrullus colocynthis Schrad. is a commonly used medicinal plant especially as a hypoglycemic agent. Case Presentation. Four patients with colocynth intoxication are presented. The main clinical feature was acute rectorrhagia preceeded by mucosal diarrhea with tenesmus, which gradually progressed to bloody diarrhea and overt rectorrhagia within 3 to 4 hours. The only colonoscopic observation was mucosal erosion which was completely resolved in follow-up colonoscopy after 14 days. Conclusion. The membranolytic activity of some C. colocynthis ingredients is responsible for the intestinal damage. Patients and herbalists should be acquainted with the proper use and side effects of the herb. Clinicians should also be aware of C. colocynthis as a probable cause of lower GI bleeding in patients with no other suggestive history, especially diabetics.
Background: Cisplatin is a potent anticancer drug, but its nephrotoxicity limits the clinical use of it. To reduce the Cisplatin-induced nephrotoxicity, various interventions have been implicated. The aim of this study was to examine whether preconditioning with normobaric hyperoxia would prevent Cisplatin-induced nephrotoxicity in patient with solid tumor. Methods: In a prospective study, 80 adult patients with solid tumor who were treated with Cisplatin between February 2011 and December 2011 were included. Forty-three patients were exposed to pure oxygen via non-rebreathing reservoir mask which increased the provided oxygen rate to 60% oxygen for 2 hours at 48, 24, and 6 hours before intravenous administration of Cisplatin and 37 patients received only Cisplatin as a control group. Estimated glomerular filtration rate (eGFR) calculated in all patients on day 1 before and on days 1, 3, 6, 30 after Cisplatin exposures. Results: Patients treated with Cisplatin and 60% oxygen showed a mild improvement in eGFR and mild reduction of serum creatinine after 30 days with statistically mild significant differences (p ¼ 0.048). Conclusion: This study showed that normobaric and intermittent precondition of 60% oxygen prior to Cisplatin treatment had an acute transient adverse effect on renal function; however, the improvement of renal function will be seen after 30 days. Thus, it may help to prevent Cisplatin nephrotoxicity.
Background:The overcrowded hospital is an unsafe one. Overcrowding the emergency department (ED) results in increased patient suffering, prolonged waiting time, deteriorating level of service, and on occasion, a worsened medical condition or even death.Objectives:This study proposes a strategy to overcome ED overcrowding.Materials and Methods:The proportion of acute area admitted patients to screened patients (A/S), and the proportion of patients who were finally transferred to inpatient wards (W/A) to those admitted in ED acute area were investigated during 6 consecutive months. Emergency medicine residents were assigned to screen patients before ED admission and afterwards.Results:The average A/S changed from 82.4% to 44.2% (P = 0.028), and the average W/A changed from 28.3% to 51.48% (P = 0.028) before and after screening patients respectively. The initiative resulted in 97 less patients in the acute area per day.Conclusions:Decreased number of acute area admitted patients, and increase W/A proportion showed that the initiative was successful in obviating ED overcrowding while provision of care to those most in need was not altered.
three domains of input, throughput and output of ED conceptual model (2, 3) to overcome the problem of ED overcrowding. Two well-known input interventions are "Streaming" (e.g. dividing patients into those who would benefit from admission and those who could be treated as outpatients) and assigning physicians in charge of triage. Our hospital ED, is an academic medium-volume tertiary healthcare ED which has a rapid screening zone, where patients are initially evaluated and separated into two main streams: Those who are to be admitted in ED acute area and those who can be managed as outpatients. Patients used to be evaluated by general practitioners in the rapid screen zone. But from October 2010, EM residents trained by the EM department were assigned to BackgroundThe overcrowded hospital is an unsafe one. Overcrowding in Emergency Departments (ED) is a common problem, which alters patients' safety, treatment, privacy and patient satisfaction in addition to increasing the risk of staff frustration. Mitigating overcrowding may have positive effects for patients as well as residents' (1). Various interventions have been examined in each ofBackground: The overcrowded hospital is an unsafe one.
