Atypical Presentation of Massive Pulmonary Embolism, a Case Report.

The lack of pathognomonic signs and symptoms makes the diagnosis of pulmonary embolism (PE) difficult. Here, we report a case of a 42-year-old man presented to the emergency department with worsening epigastric pain, hypotension, frank bradycardia, and final diagnosis of PE. Although previous studies have indicated that abdominal pain was observed in 6.7% of patients with PE, the exact reason for abdominal pain in PE still remains unknown. Tension on the sensory nerve endings, hepatic congestion, and distention of Gilson's capsule are some of the possible mechanisms of abdominal pain in PE. We conclude that emergency physicians should pay more attention to PE, which is an important differential diagnosis of shock state. In this context, rapid ultrasound in shock (RUSH) should be considered as a vital sign that needs to be evaluated when recording the history of patients presented to the emergency department with signs and symptoms of shock.

Citrullus colocynthis as the Cause of Acute Rectorrhagia.

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.

Assigning residents of emergency medicine to screen patients before admission: a strategy to overcome overcrowding.

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.
