Case Reports
Round opacity as a presentation of pneumocystis jirovecii pneumonia in an HIV-infected patient.
We present the case of a human immunodeficiency virus (HIV)-infected patient who arrived at our emergency department with fever, headache and exertional dyspnea. Throughout their stay, a chest x-ray was taken and a rounded opacity in his left lung was observed. CT images showed same abnormality and also ground glass opacities were seen. ⋯ Once available, flexible bronchoscopy and bronchoalveolar lavage was performed and stained preparations from his respiratory specimens confirmed the diagnosis of pulmonary pneumocystis infection. Finally, after 4 days of antibiotic therapy, an important clinical improvement was documented; a new chest x-ray was performed and the previous rounded opacity was absent. This finding strongly suggested a case of round pneumonia.

Appendicitis is the most common surgical emergency in children, of which most are located in the retrocecal space or pelvis. Appendicitis occurring in the subhepatic space is uncommon and may present with atypical features such as right upper quadrant pain, leading to delayed diagnosis and complications. We present a rare case of subhepatic appendicitis in an 11-year-old female, who presented with a three-day history of both right upper quadrant (RUQ) and right lower quadrant (RLQ) abdominal pain and serum lipase elevated four times the upper normal limit. ⋯ Our patient encounter demonstrates the need to be aware of the atypical presentations of pediatric appendicitis in general and subhepatic appendicitis in particular. Moreover, to our knowledge, this is the first reported case of elevated lipase (with a radiographically normal pancreas) in association with subhepatic appendicitis. Providers should be aware elevated serum lipase levels may be due to conditions other than pancreatitis and further evaluation should be considered if the elements of the clinical picture are incongruent.

Comparative Study Observational Study
Arterial pH selectively predicts critical care needs in emergency department obese patients with acute dyspnea: A prospective comparative study.
Obese patients with acute dyspnea may be prone to misorientation from the emergency department (ED), due to impaired gas exchange evaluation and altered basal respiratory profiles. This study aims to evaluate the prognostic value of arterial blood pH in obese ED patients with acute dyspnea in comparison to non-obese counterparts. ⋯ Arterial blood pH may selectively predict critical care needs in ED obese patients with acute dyspnea, in comparison to non-obese. A falsely reassuring pH < 7.36 should be regarded as a marker of severity when assessing acute dyspnea in obese ED patients.

We sought to develop a practical Bedside Score for the diagnosis of cholecystitis and test its accuracy against the Tokyo Guidelines (TG13). ⋯ A clinical prediction score for cholecystitis demonstrates accuracy equivalent to TG13. Use of this score may streamline work-up by decreasing the need for comprehensive ultrasound evaluation and CRP measurement and may shorten ED length of stay.
