Published: August 2022

Isolated pulmonic valve infective endocarditis (PV-IE) is a rare form of endocarditis. The authors report a case of giant vegetations detected by transthoracic echocardiography (TTE) on PV in a young patient, 33-year-old, with drug abuse history. The patient underwent surgical intervention by pulmonary valved bioconduit implantation. After operation, a pulmonary embolism episode was treated by a direct oral anticoagulant. The final outcome was favorable. The difficulty in diagnosing PV-IE is due to the inability to properly visualize the PV by echocardiography. In this case, with such large vegetations, TTE allowed a correct diagnosis and an effective surgical planning, confirming its importance as a diagnostic tool.

Article Synopsis
  • A challenging case involved a 31-year-old female intravenous drug user who presented with severe symptoms, including fever and shortness of breath, and was diagnosed with high-grade MSSA bacteremia and multiple pulmonary emboli.
  • Despite having significant heart complications like a large vegetation on the pulmonic valve, the patient was treated without valve replacement and was closely monitored with follow-up care and additional medications.

Article Synopsis
  • Platelets inherit RNA from their parent megakaryocytes and this study uses single-cell RNA sequencing to investigate the platelet transcriptome, which has not been thoroughly explored before.
  • Findings revealed significant variability in gene expression among platelets, with common markers showing lower than expected abundance and highlighting that current identification methods often misclassify platelets.
  • The research stresses the importance of specialized sequencing techniques for accurate platelet profiling, which could lead to advancements in understanding platelet biology and their potential use in immune therapy and as biomarkers for diseases like cancer.

Isolated Pulmonic Valve Endocarditis: A Rare Clinical Entity.

Clin Med Insights Case Rep

August 2024

Department of Internal Medicine, School of Medicine, College of Medicine and Health Sciences, University of Gondar, Gondar, Ethiopia.

Article Synopsis
  • Isolated pulmonic valve endocarditis is a rare heart valve infection, making up only 1-2% of all infective endocarditis cases, and was diagnosed using modified Duke's criteria in this case.
  • A 52-year-old male presented with symptoms like body swelling, prolonged fever, cough, and discolored urine, alongside signs of heart failure and other health issues detected during examination and lab tests.
  • Diagnosis was confirmed by echocardiography showing vegetations on the pulmonic valve, supported by the presence of one major and three minor criteria from the modified Duke's criteria, leading to significant improvement after two weeks of intravenous treatment.

Rhodococcus Empyema in an Immunocompetent Patient.

Cureus

November 2023

Infectious Disease, Ascension Health, Grand Blanc, USA.

is a gram-positive, facultative intracellular coccobacilli that most commonly causes pulmonary infections in animals and, rarely, in immunocompromised humans. Infected patients typically experience severe pulmonic infections such as necrotizing or cavitary pneumonia. We describe a rare case of that was isolated from an empyema in a 66-year-old immunocompetent patient experiencing recurrent pleural effusions requiring multiple interventions.

Right-sided endocarditis is a rare entity, with various series reporting an incidence of 5%-10%. Pulmonary valve (PV) is not only the least commonly involved valve in infective endocarditis (IE), with an incidence of 1.5%-2%, but 'isolated' pulmonic valve endocarditis (PVE) without tricuspid valve involvement is even rarer with limited published data.
