[Platypnea-orthodeoxia syndrome in a patient with heart failure: A case report].
Rev Med Interne
December 2024
Service de pathologies cardiovasculaires, hôpital d'instruction des armées Laveran, 34, boulevard Laveran, CS 50004, 13384 Marseille, France.
Introduction: The platypnea orthodeoxia syndrome is a rare clinical entity combining positional dyspnea and arterial oxygen desaturation during the transition to orthostatism, reversible on return to decubitus. The most frequent etiology of this syndrome is the presence of a patent foramen ovale (PFO) responsible for a right-to-left intracardiac shunt, the severity of which results in significant functional disability and a risk of death from hypoxia.
Case Report: We report the case of a 93-year old patient on long-term oxygen, initially hospitalized for acute heart failure following a community-acquired urinary tract infection.
Catheter embolization for pulmonary arteriovenous malformations during chemotherapy for appendiceal adenocarcinoma: A case report of associated brain abscess.
Radiol Case Rep
November 2024
Department of Diagnostic and Interventional Radiology, Osaka International Cancer Institute, 3-1-69 Otemae, Chuo-ku, Osaka 541-8567, Japan.
Article Synopsis
- * These malformations can lead to right-to-left shunts in the lungs, increasing the risk of central nervous system issues like brain abscesses or strokes, particularly during chemotherapy treatment.
- * A case study highlights a 68-year-old woman with PAVMs and appendiceal adenocarcinoma who developed a brain abscess during chemotherapy, suggesting that careful monitoring and possible pre-chemotherapy embolization of PAVMs could be important for managing complications.
Sex differences in chest electrical impedance tomography findings.
Physiol Meas
July 2024
Department of Anaesthesiology and Intensive Care Medicine, University Medical Centre Schleswig-Holstein, Campus Kiel, Kiel, Germany.
Electrical impedance tomography (EIT) has been used to determine regional lung ventilation distribution in humans for decades, however, the effect of biological sex on the findings has hardly ever been examined. The aim of our study was to determine if the spatial distribution of ventilation assessed by EIT during quiet breathing was influenced by biological sex.219 adults with no known acute or chronic lung disease were examined in sitting position with the EIT electrodes placed around the lower chest (6th intercostal space).

June 2024
Department of Medicine and Epidemiology, University of California Davis, Davis, California, USA.
Background: There is controversy about the clinical relevance of congenital variants of the ventral laminae of the sixth (C6) and seventh (C7) cervical vertebrae and their relationship with other radiological abnormalities.
Objectives: To document the prevalence of congenital variants of C6 and C7 and that of other radiological abnormalities from C6 to the second thoracic vertebra (T2).
Study Design: Cross-sectional.
Congenital continuous retrograde basilar flow suggests type B interrupted aortic arch in a neonate: A case report.
SAGE Open Med Case Rep
April 2024
Department of Pediatrics, Pediatric Critical Care Division, University of South Alabama, Mobile, AL, USA.
Article Synopsis
- * The echocardiogram identified significant heart defects, including an interrupted aortic arch and a large ventricular septal defect, but the presence of a patent ductus arteriosus prevented immediate complications from this reversed flow.
- * Ultimately, the infant was diagnosed with DiGeorge syndrome, underwent corrective surgery for the interrupted aortic arch, and restored normal blood flow in the basilar artery, highlighting the critical nature of recognizing these congenital vascular anomalies.
