The return visit, outcome and predicting factors of return visit among suspected COVID-19 outpatients.

Rate of return visit, predicting factors of return visit and occurrence of adverse events in suspected to be or likely cases of COVID-19 patients who received outpatient treatment. This is a retrospective observational cohort study on patients (> 16 years), suspected to be or likely cases of COVID-19 who were visited in a respiratory emergency department and subsequently discharged home. Patients' baseline characteristics were extracted from medical charts. All patients were followed-up for 7 days after their first visit. Patients' outcomes during the7-day follow-up, as well as the severity of pulmonary involvement based on imaging were recorded. A total number of 601 patients (350 men and 251 women) were recruited. The rate of return visit was 27.74% (144 patients) with 6.74% (34 patients) experiencing a poor outcome. Six factors with a significant odds ratio were predictors of poor outcome in patients who received outpatient treatment, namely, older age [odds ratio = 3.278, 95% confidence interval: 1.115-9.632], days from onset of symptoms [1.068, 1.003-1.137], and history of diabetes [6.373, 2.271-17.883]). Predictors of favorable outcome were female gender [0.376, 0.158-0.894], oxygen saturation > 93% [0.862, 0.733-1.014], smoking habit [0.204, 0.045-0.934]. The findings of this study demonstrate that the rate of return visit with poor outcome in patients who received outpatient treatment was reasonably low. Age, male sex, diabetes mellitus and pulmonary disease are predicting factors of poor outcome in these COVID-19 patients who received outpatient management.

Atypical Presentation of Acute Appendicitis: A 32-year-old Man with Gastroenteritis Symptoms; an Educational Case.

INTRODUCTION: Appendicitis is a common condition that almost always requires emergency surgery. The diagnosis is clear when the patient presents with classic symptoms. However, presentation may be variable due to variations in the position and length of the appendix. CASE PRESENTATION: Here, we report a 32-year-old man who presented with diarrhea and lower abdominal pain. Physical examination revealed a generalized abdominal tenderness, more prominent in the lower abdomen, including the right and left quadrants. Abdominal ultrasound failed to show any findings supportive of the diagnosis of appendicitis. Further investigation with abdominopelvic computed tomography (CT) with intravenous and oral contrast revealed retrocecal appendicitis. The patient was discharged home after a non-complicated appendectomy. CONCLUSION: Emergency physicians should be aware that appendicitis may not always show up with a typical presentation and they should consider the possibility of appendicitis when evaluating an acute abdomen to prevent any delay in diagnosis of atypical presentations.

Jejunal Perforation Following Blunt Abdominal Trauma; a Case Report.

INTRODUCTION: The possibility of intestinal injury for all patients presenting to emergency department (ED) with blunt abdominal trauma, despite minimal physical signs should be considered. To highlight the patient management, hear, we report a case of hollow viscus injuries resulting from blunt abdominal trauma referring to a teaching hospital in Tehran, Iran. CASE PRESENTATION: A 30-year-old man presented to the ED after "falling into a hole" with his back and had direct blunt abdominal trauma by a heavy bag of cement. In physical examination, there was a mild abdominal tenderness on right upper quadrant. On bedside ultrasonography, there was small free fluid in his Morison's pouch without hypotension. So abdominal CT scan was performed which revealed free fluid in pelvic, perihepatic, and perisplenic spaces. Mural hematoma of proximal part of jejunum with mural wall hypodensity in mid jejunal loop were also revealed. The patient underwent surgery, and there was damage to the colon serosa and jejunal perforation which was primarily repaired. CONCLUSION: The presented case highlights the importance of obtaining history and physical exam and paying attention to the nature and mechanism of injury. Emergency physicians should be aware of hollow viscus injury in traumatic patients. Any delay in diagnosis and operative management are associated with an increase in mortality.
