Point-of-care ultrasound in infectious diseases: Current insights and future perspectives.

Point-of-Care Ultrasound (POCUS) is a safe, non-invasive technique performed at the patient's bedside, providing immediate results to the operator. It complements physical examination and facilitates clinical decision-making. In infectious diseases, POCUS is particularly valuable, offering an initial assessment in cases of suspected infection. It often leads to an early tentative diagnosis enabling the prompt initiation of antimicrobial treatment without the delay associated with traditional radiology. POCUS provides direct visualization of affected organs, assists in evaluating fluid balance and facilitates various interventions, all while reducing patient discomfort. For infectious disease specialists, becoming proficient in POCUS is a critical future challenge, requiring dedicated training for effective utilization.

Recurrent bacteremia and endocarditis due to Staphylococcus capitis in a patient with Bowen's disease: a case report.

This case report details the management of a 79-year-old male with recurrent methicillin-resistant Staphylococcus capitis bacteremia and endocarditis. The patient's clinical journey encompassed multiple hospital admissions, with challenges in managing endocarditis, pacemaker replacements, and potential cutaneous sources of infection. The treatment regimen included intravenous antibiotic therapy during hospitalization and suppressive antibiotic treatment upon discharge, alongside a decolonization strategy for his scalp lesions.

Multi-organ clinical ultrasound as a complement to the diagnostic process in an internal medicine consultation.

INTRODUCTION: Evaluating outpatient cases in internal medicine consultations presents a significant diagnostic challenge. Ultrasound can be a highly useful tool in assessment and decision-making. PATIENTS AND METHODS: A prospective observational study was conducted on a cohort of patients attending an internal medicine rapid assessment clinic. Eighty patients were prospectively recruited. A medical consultation was conducted as per usual clinical practice, followed by a POCUS evaluation; collecting pulmonary, cardiac, and abdominal data. All findings were analyzed and recorded, particularly those that were significant or altered the initial diagnosis, subsequent tests, or treatment. RESULTS: Significant ultrasound findings were found in 37.5% of the patients. Of all ultrasound scans, the most clinically relevant were in the heart region (31.9%), followed by the abdomen (26%). These findings led to a change in overall management in 27.5% of patients. Using logistic regression, a model was developed to estimate the presence of clinically relevant findings with an area under the curve (AUC) of 0.78 (95% CI 0.66-0.89; p < 0.001) with 80% Sensitivity and 66% Specificity. CONCLUSION: The systematic and standardized incorporation of clinical ultrasound in internal medicine consultations contributes to decision-making, can provide significant findings that allow for modifications in clinical suspicion and therapeutic management.
