Although computed tomography (CT) scan can identify urinary obstruction caused by stones, there is a growing concern about exposure to radiation made by this method. Renal scintigraphy can provide valuable insights regarding the functional status of kidneys and can significantly reduce exposure to radiation. The goal of present study was to assess renal function through renal scintigraphy in patients with acute renal colic and it explores the association between renal scintigraphy performance and ultrasound in terms of detecting hydronephrosis. Methods: For this study, 20 patients with acute renal colic were chosen. Each patient underwent renal ultrasonography and subsequently received renal scintigraphy with Technetium-99m diethylenetriaminepentaacetic acid (Tc-99m DTPA). Cohen's Kappa coefficient and Cramer's V correlation were employed to demonstrate the extent of agreement between ultrasound and renal scintigraphy. Results: 12 (60%) patients were male. Glomerular filtration rate (GFR) values were correlated with Cockcroft-Gault equation and the Gates method (P=0.002, r=0.642). There was a good agreement and a statistically significant relationship between ultrasound and renal scintigraphy in terms of detecting obstructive uropathy in both kidneys. Conclusion: To conclude, GFR values were correlated between Cockcroft-Gault equation and the Gates method in patients with acute renal colic. There was a good agreement and statistically significant relationship between ultrasound and obstructive renography results in both kidneys. However, we found no association between perfusion phase of renal scintigraphy and ultrasonography in terms of hydronephrosis detection. https://fem.tums.ac.ir/index.php/fem/article/view/1240 https://fem.tums.ac.ir/index.php/fem/article/download/1240/457

Vegans are at high risk of severe B12 deficiency as the primary source is animal products. Right now, the total number of vegans, vegetarians, and all related categories, is close to 14 per cent of the world population. We here present a young vegan with severe B12 deficiency presenting with sub-massive thromboembolism. https://fem.tums.ac.ir/index.php/fem/article/view/1200 https://fem.tums.ac.ir/index.php/fem/article/download/1200/459

Given that identifying the challenges of this area in facing various crises, especially COVID-19, can be a road map for preparing and planning for crisis management in the future, the current study was conducted with the aim of identifying the challenges of prehospital emergency in facing the corona pandemic. Methods: The present systematic review was carried out based on the PRISMA protocol. The search was conducted using the keywords “challenges, obstacles, prehospital emergency and COVID-19” in PubMed, Scopus, and Web of Science databases, and Google Scholar search engine between December 15, 2019 and March 20, 2023. Non-English articles and articles outside the scope of the COVID-19 pandemic were excluded from the study. CASP (critical appraisal skills program), JBI (Joanna Briggs institute) and MMAT (mixed methods appraisal tool) checklists were used to evaluate the quality of the articles. Results: Based on the searches, 12 articles were finally evaluated. Challenges extracted from the analysis of studies were classified into 3 main categories and 7 subcategories including the main categories of “process, structural, and psychological challenges” and the subcategories of “lack of equipment, inappropriate management of human resources, deficiencies in protocols and instructions, weak staff training, occupational burnout, and weak socio-organizational support”. Conclusion: The prehospital emergencies of the countries have faced some challenges after the outbreak of COVID-19, which requires the implementation of adaptive strategies and the efforts of the authorities to solve them to prepare for similar crises.  https://fem.tums.ac.ir/index.php/fem/article/view/1211 https://fem.tums.ac.ir/index.php/fem/article/download/1211/462

According to some reports, this group has the highest burnout level among different medical specialities. It is necessary for the professionals in this field to zoom out once in a while. Sabbaticals are good opportunity for this purpose among academics. This period not only provides a time window to get away from work stress, it also helps to broaden people's view via learning new materials. Over one year, September 2022 – August 2023, I completed my Master of Science in epidemiology degree at the University of Ottawa. In addition, the work at the Ottawa hospital research institute (OHRI) which is well known across the world for its excellence in EM research provided me a unique opportunity to participate in some research studies.

This study aims to determine the temporal trend of patient attendance and staffing in a major tertiary hospital ED to assist in establishing an optimal staffing pattern. Methods: A 1-year retrospective ED census review of adult patients at the University of the Philippines-Philippine General Hospital (UP-PGH) was undertaken. One-way analysis of variance (ANOVA) with post hoc Fisher-Hayter pairwise comparisons were utilized to determine if the ED consults and admissions were significantly (P<0.05) associated with the month of the year and day of the week. Results:  A total 43,632 consults at the UP-PGH ED, averaging of 3,636 per month or 121 per day, were seen in 2019. Results indicated statistically significant differences between monthly [F (11,353) =16.45; P<0.0001] and between daily means [F (6,358) =4.19; P=0.0004]. The most number of consults occur during August, September, October and November while admissions were highest during April and October.  It was busiest during Mondays and afternoon shifts (1400-2200 hours) with majority arriving as urgent in acuity. Mortality was also highest during the afternoon shifts. Conclusion: The temporal variations in patient visits and acuity described in our study can be used as a template for workforce scheduling and resource allocation to meet the demands in the provision of care at the ED. https://fem.tums.ac.ir/index.php/fem/article/view/1243 https://fem.tums.ac.ir/index.php/fem/article/download/1243/456

However, although rare, thyroid dysfunction may present a similar clinical picture with equally serious and life-threatening consequences. Therefore, every occurrence of acute dyspnea represents a special medical challenge in diagnosis and treatment. We present a case of 81-year-old male admitted to the rehabilitation department five days after a knee joint total endoprosthesis and developed acute dyspnea two days later. An emergency diagnostic was performed and confirmed an airway stenosis through a previously undiagnosed enlarged thyroid gland. Although in most cases an acute life-threatening postoperative dyspnea indicates a cardiac or pulmonary problem, other diseases must be taken into consideration. https://fem.tums.ac.ir/index.php/fem/article/view/1258 https://fem.tums.ac.ir/index.php/fem/article/download/1258/460

Pandemic diseases like COVID-19 increase the prevalence of psychological problems in the community. Studying psychological problems and associated factors in the community is very crucial for community mental health management. However, evidence is scarce in Ethiopia. Therefore, this study aimed to assess the prevalence of psychological problems and factors in the community during the COVID-19 pandemic in Shashemene Town, Oromia, Ethiopia. Methods: A community-based cross-sectional study was conducted from February 01,2012 to February 28, 2021.  A structured, pretested, and interviewer-administered questionnaire was used to collect data from 889 study participants selected through a simple random sampling technique. The data was collected using the depression, anxiety, and stress scale (DASS-21) questionnaire and analyzed using SPSS version 25.0. Bivariable and multivariable logistic regression was done to determine factors associated with DAS. Adjusted odds ratio with their 95% confidence intervals were calculated to identify the presence and strength of an association, while statistical significance was reported at P<0.05. Results: The prevalence of psychological problems was 96.6% [95% Cl: 95.9,98.1]. The overall prevalence of depression and anxiety were 30% and 43.5% respectively. Having COVID-19 symptoms in the past two weeks before the survey (AOR=0.34; 95% Cl: 0.15,0.77) and having known medical problems (AOR=0.28; 95% Cl: 0.13,0.59) were factors significantly associated with a psychological problem in response to COVID-19 pandemic. Conclusion: The prevalence of psycholog: The results from this review indicate that the chest CT scan should be used for symptomatic and hospitalized patients. Moreover, chest CT scan should not be used as a primary screening tool for diagnosing COVID-19. Application of RT-PCR as the first line diagnosis is still recommended. https://fem.tums.ac.ir/index.php/fem/article/view/459 https://fem.tums.ac.ir/index.php/fem/article/download/459/311

Unique challenges, however, are expected under these circumstances beyond what occurs during normal conditions. EMS personnel often have limited information about their patients, work under uncontrolled conditions, and accompany their patients in enclosed spaces of the ambulance. They are at particular risk of contracting the infectious agent unless standard and transmission-based precautions are implemented. Appropriate use of personal protective equipment (PPE) by responding personnel is, therefore, of paramount importance. Since the report of the first cases of COVID-19 in late December 2019, the disease has spread beyond China. As of March 29th, a total of 634,835 confirmed cases have been reported globally and 29,975 people have died. The Center for Diseases Control (CDC) and other authorities and advisory agencies have prepared guidelines regarding safety precautions for EMS personnel, including appropriate selection and use of PPE . https://fem.tums.ac.ir/index.php/fem/article/view/376 https://fem.tums.ac.ir/index.php/fem/article/download/376/274

People were advised to stay in-doors to prevent the spread of this deadly disease, and this slogan helped to a greater extent in containing the spread of the virus. Unfortunately, there is no treatment for the disease at present, but extensive research is going on to find a definitive treatment. Regarding endotracheal intubation (ETI) of COVID-19 patients, data are scarce and no randomized clinical trials are available to develop and formulate succinct and acceptable guidelines in tackling the problem of ETI in these highly risky and vulnerable patients. https://fem.tums.ac.ir/index.php/fem/article/view/374 https://fem.tums.ac.ir/index.php/fem/article/download/374/276

The effects are felt right across the World with certain geographical areas being most affected, it has affected all countries irrespective of their healthcare infrastructure. It has been suggested that certain parts of World that are prone to natural disasters are better prepared for pandemics. However, this is completely unfound as major economies are overwhelmed with the effects of the COVID-19 and it becomes completely irrelevant of any past experiences as these have been in never seen before scale. Evidence acquisition: The national fight against COVID-19 has been dubbed as the greatest fight for the National Health Service (NHS) with the entire United Kingdom under lockdown and the unfamiliar situation not seen before in peacetime. The general understanding of the disease process is that it has profound effects on the elderly and those with significant underlying health conditions such as cardiovascular, respiratory amongst others. However, it has surfaced from time to time that the very young are being affected and at times unfortunately been fatal. Results/Measures: The United Kingdom has been in a lockdown just like several nations across the globe in a desperate measure to limit the spread of the virus. There have been weeks of planning at every level for all possible eventualities with regards to the ongoing COVID-19 pandemic. All routine operations a
