Diagnostic Accuracy of Early Systolic Notching in Pulmonary Embolism.

OBJECTIVE: Recently, a cardiac sonography finding, early systolic notching (ESN), was reported with high sensitivity and specificity for the diagnosis of pulmonary embolism (PE) in a limited population. The aim of this study was to determine the diagnostic accuracy of ESN finding for PE in emergency department (ED) patients. METHOD: This prospective multicenter study was conducted in 4 academic EDs. All patients who underwent computed tomography angiography for suspected PE were included in the study. After inclusion, cardiac ultrasound including the right ventricular outflow tract Doppler signal was performed. The diagnostic tests of ESN finding were used for PE and its subgroups. RESULTS: In the study, 183 of 201 patients met the study criteria. Of all patients, 52.5% had PE (n = 96), and 19.7% (n = 36) had ESN finding. In all ED patients, the sensitivity of ESN for PE was 34% (95% CI 25-45), and the specificity was 97% (95% CI 90-99). In the subgroup analysis, the sensitivity of ESN for PE with high or intermediate-high risk was 69% (95% CI 49-85), and the specificity was 90% (95% CI 84-94). Inter-rater reliability for ESN finding between the cardiologist and emergency physician was strong with a kappa statistic of 0.87. CONCLUSION: The pulmonary Doppler flow of ESN was moderate to high specific but low sensitive for PE in all ED patients. In the subgroup analysis, this finding was moderate specific and low sensitive.

Untangling diagnostic confusion in internal abdominal hernias.

BACKGROUND: Internal hernias involve the herniation of intestines through mesenteric or peritoneal defects in the gastrointestinal system. Etiologically, they are generally classified as congenital or acquired. Internal hernias often present with non-specific symptoms. Despite the increased use of computed tomography (CT), discrepancies between imaging findings and diagnostic accuracy continue to pose challenges for clinicians. This study aims to compare the outcomes of patients presenting to the emergency department with abdominal pain and receiving a preliminary internal hernia diagnosis through CT, followed by laparotomy. METHODS: Our research is a retrospective, observational, and descriptive study. It includes patients presenting to the emergency department with abdominal pain, who were provisionally diagnosed with internal hernia based on CT. Patient data recorded age, gen-der, CT-identified internal hernia type, surgery, diagnoses, hospitalization status, duration of hospital stay, bowel resection, mortality, and blood parameters. The Welch classification was used to categorize internal hernia types, with eight types examined. RESULTS: Among 112 patients with a preliminary internal hernia diagnosis based on abdominal CT, the median age was 52 years. Of these, 46 were female and 66 were male. Among all patients, 87 were admitted to the hospital for observation and surgery, while 25 were discharged after emergency department. Paraduodenal hernias were the most common provisional diagnosis (48 cases). Among these patients, 45 were discharged after symptom relief and were advised for elective re-evaluation. The exact diagnosis for these pa-tients remains unknown. Post-surgery, the diagnosis of internal hernia was confirmed in 32 cases. Among them, 15 were female and 17 were male, with a median age of 52. The median hospital stay for patients diagnosed with internal hernia was 5 days. Although acquired hernias exhibited higher resection and mortality rates, no statistically significant difference was found. Thirty-five cases received dif-ferent diagnoses: 19 had brid ileus, five had volvulus, six had acute appendicitis, one had duodenal perforation, three had gynecological malignancies, and one had renal malignancy. CONCLUSION: Although internal hernias are rare, early diagnosis and treatment are very important due to the high risk of death. The study findings indicate that increased CT utilization leads to earlier diagnosis and treatment, resulting in improved prognosis for patients. This study holds one of the largest case series in the literature. It provides a novel perspective by evaluating radiologically-diagnosed cases, confirming diagnoses post-surgery, and comparing conditions that mimic internal hernias, thereby making a valuable contribution to the literature.

Trends in medical students' career choice of emergency medicine: A 14-year study.

INTRODUCTION: The long-term trends of medical students' choice for emergency medicine (EM) in Turkey are unclear. With this background, we aimed to determine the change in the rate of EM preferences of students over the years. METHODS: This was a cross-sectional study originated from 6th-year medical students' feedback forms, to examine trends of EM carrier preferences between 2005 and 2018 in a tertiary care academic emergency department. There are two main questions containing "would you choose EM as a specialty?" and "why?" as open-ended questions in the form. The answers to the open-ended question were classified as six main factors, which were perception of work, lifestyle, nature of work, personal job preference, mentorship/department experiences, and income. RESULTS: During the study, 2957 forms (80.6% of 3668) were completed by 6th-year medical students. Of the students, 26.5% (n = 784) responded "yes" to the question, which was "would you choose EM as a specialty?," 6.1% (n = 181) responded "do not know," and 67.4% (n = 1992) responded "no." In 2005, 15% of students stated that they would choose EM, while this rate increased to 29% in 2018 (χ 2: 9.67; P trend = 0.003). Perception of work was the most common reason for "yes" (46.3%), "no" (46%), and "do not know" answers. CONCLUSION: The rate of EM choice of medical students doubled during the study, and approximately one in three students stated that they could choose EM as their future career in the past year. Perception of work was the main factor for choosing or rejecting to EM.
