ABSTRACT
Sweet syndrome (SS) is a rare inflammatory disorder characterized by the rapid onset of a characteristically tender rash, fever, and other systemic symptoms. These manifestations are often mistaken for an infection that is not responding to antimicrobials, especially in immunocompromised hosts. We present the case of a 44-year-old woman who developed SS following induction chemotherapy for newly diagnosed acute myeloid leukemia (AML). She exhibited a painful rash on the anterior chest, which spread centrifugally, along with neutropenic fever unresponsive to broad-spectrum antimicrobials. Biopsy of the rash revealed a dense neutrophilic infiltrate within the dermis, confirming the diagnosis of SS. The patient was subsequently treated with systemic steroids with prompt resolution of fevers and improvement of her rash. This case highlights that SS can manifest with a robust neutrophilic infiltrate, even in the context of neutropenia stemming from chemotherapy. SS serves as a crucial consideration in hematologic malignancies, particularly AML, when patients present with fever and cutaneous eruptions. Prompt recognition followed by systemic steroid therapy often leads to symptom resolution.
ABSTRACT
BACKGROUND: In response to growing concerns regarding the overuse of coronary computed tomography angiography (CCTA) in the clinical setting, multiple societies, including the American College of Cardiology Foundation, have jointly published revised criteria regarding the appropriate use of this imaging modality. However, previous research indicates significant discrepancies in the rate of adherence to these guidelines. AIM: To assess the appropriateness of CCTA referrals in a tertiary cardiac center in Bahrain. METHODS: This retrospective clinical audit examined the records of patients referred to CCTA between the April 1, 2015 and December 31, 2015 in Mohammed bin Khalifa Cardiac Center. Using information from medical records, each case was meticulously audited against guidelines to categorize it as appropriate, inappropriate, or uncertain. RESULTS: Of the 234 records examined, 176 (75.2%) were appropriate, 47 (20.1%) were uncertain, and 11 (4.7%) were inappropriate. About 74.4% of all referrals were to investigate coronary artery disease (CAD). The most common indication that was deemed appropriate was the detection of CAD in the setting of suspected ischemic equivalent in patients with an intermediate pretest probability of CAD (65.9%). Most referrals deemed inappropriate were requested to detect CAD in asymptomatic patients at low or intermediate risk of CAD (63.6%). CONCLUSION: This audit demonstrates a relatively low rate of inappropriate CCTA referrals, indicating the appropriate and efficient use of this resource in the Mohammed bin Khalifa Cardiac Center. Agreement on and reclassification of "uncertain" cases by guideline authorities would facilitate a deeper understanding of referral appropriateness.
