Background: During the coronavirus disease 2019 (COVID-19) pandemic, the simultaneous detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and Influenza A, and Influenza B viruses is essential for rapid differential diagnosis in patients with similar symptoms, especially during "flu season" in the post-pandemic era. So far, several multiplex methods have been approved for the simultaneous detection of SARS-CoV-2, Influenza A, and Influenza B. However, due to the rapid mutation rate of the SARS-CoV-2 genome and the emergence of new variants, existing methods must be improved and updated.

Although the current vaccines have a pivotal role in the control of this pathogen, the emergence of new variants has a negative impact on their effectiveness.
View Article and Find Full Text PDFBackground: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is currently the most important etiological agent of acute respiratory distress syndrome (ARDS) with millions of infections and deaths in the last 2 years worldwide. Several reasons and parameters are responsible for the difficult management of coronavirus disease-2019 (COVID-19) patients; the first is virus behavioral factors such as high transmission rate, and the different molecular and cellular mechanisms of pathogenesis remain a matter of controversy, which is another factor.
Summary: In the present review, we attempted to explain about features of SARS-COV-2, particularly focusing on the various aspects of pathogenesis and treatment strategies.
Background: Diagnosis of COVID-19 can be challenging in trauma patients, especially those with chest trauma and lung contusion.
Methods: We present a case series of patients from February and March 2020 who were admitted to our trauma center at Rajaee Hospital Trauma Center, in Shiraz, Iran and had positive SARS-CoV-2 PCR test or chest CT scan suggestive of COVID-19 and were admitted to the specific ICU for COVID-19.
Results: Eight COVID-19 patients (6 male) with mean age of 40 (SD = 16.
Objectives: This systematic review and meta-analysis assesses the utility of trimetazidine (TMZ) to prevent contrast induced nephropathy (CIN) in patients with renal insufficiency undergoing coronary angiography and angioplasty.
Materials And Methods: This meta-analysis was formulated and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search of databases was conducted by 2 researchers independently for clinical trials, comparing hydration plus TMZ vs conventional hydration alone for prevention of CIN through January 2020.
Background: Esophageal leiomyosarcoma (LMS) is a rare tumor that constitutes less than 1% of all malignant esophageal tumors. Concurrent occurrence of esophageal leiomyosarcoma with squamous cell carcinoma (SCC) is even rarer than isolated leiomyosarcoma.
Case Presentation: In this report, we present a case of concurrent leiomyosarcoma and SCC in a 64-year-old woman presenting with vomiting and solid dysphagia, which has not been properly diagnosed following several referrals and diagnostic modalities.
Introduction: This study was conducted to compare the effect of dexmedetomidine and labetalol on hemodynamic variables in patients undergoing microlaryngoscopy.
Material And Methods: In this randomized clinical trial study 70 patients undergoing microlaryngoscopy were involved. The patients were randomly assigned into two groups.
Background: The current study assessed a recently developed resuscitation protocol for bleeding trauma patients called the Targeted Transfusion Protocol (TTP) and compared its results with those of the standard Massive Transfusion Protocol (MTP).
Methods: Per capita utilization of blood products such as packed red blood cells (RBCs), fresh frozen plasma (FFP), and platelet concentrates was compared along with mortality rates during two 6-month periods, one in 2011 (when the standard MTP was followed) and another in 2014 (when the TTP was used). In the TTP, patients were categorized into three groups based on the presence of head injuries, long bone fractures, or penetrating injuries involving the trunk, extremities, or neck who were resuscitated according to separate algorithms.
In Iran, there are no studies addressing trauma death timing and factors affecting time of death after injuries. This study aimed to examine time distribution of trauma deaths in an urban major trauma referral center with respect to victims' injury characteristics during 2010 to 2015.This was a cross-sectional study of adult trauma-related in-hospital deaths resulting from traffic-related accidents, falls, and violence-related injuries.

View Article and Find Full Text PDFBackground: One of the main concerns in sinus surgery is blood loss due to the high vasculature of the mucosa. Tranexamic acid (TA) is an antifibrinolytic agent which reduces bleeding following certain surgical procedures.
Material And Methods: This randomized double-blinded clinical trial was performed on 70 patients with class I and II ASA (American Society of Anesthesiologists) who were scheduled for endoscopic sinus surgery under general anesthesia.
Background/aims: We aimed to evaluate which factors, if prevented, could facilitate a decrease in the rate of pilonidal sinus.
Materials And Methods: From November 2008 to 2010, all patients referred to the surgery clinic were examined by the general surgery attending physician. Patients with a diagnosis of pilonidal sinus were considered as the trial group.
Background: Pelvic fractures are among the most devastating traumatic injuries accompanied by high morbidity and mortality rate leading to catastrophic outcomes and haemodynamic consequences. Although Advanced Trauma Life Support (ATLS) recommends performing pelvic radiography in all major blunt trauma patients, several lines of evidence recommend that it can be limited to those blunt trauma patients who are haemodynamically unstable or have positive pelvic physical examination. Thus, we performed this study in order to evaluate the efficacy of routine pelvic radiography in haemodynamically stable, high-energy, blunt trauma patients.
