RESUMEN
Tracheal lipomas, though exceedingly rare among benign tracheal masses, present unique diagnostic and management challenges due to their unusual clinical course. This case report documents the presentation and surgical management of a 56-year-old male with a tracheal lipoma, a first documented case in Puerto Rico. The patient presented with progressive dyspnea and stridor, initially misdiagnosed and treated as asthma exacerbations. Imaging confirmed a pedunculated tracheal mass, prompting emergency surgical intervention to secure the airway and excise the mass successfully. Histopathological analysis confirmed the mass as a benign tracheal lipoma. This case emphasizes the importance of considering rare tracheal tumors in the differential diagnosis of unexplained respiratory distress and advocates for tailored management strategies informed by comprehensive multidisciplinary approaches.
RESUMEN
A novel series of ferrocenyl chalcone ammonium and pyridinium salt derivatives were synthesized in order to improve their solubility in aqueous media. Substituted ferrocenyl chalcones with amines and pyridines were synthesized using the base-catalyzed Claisen-Schmidt reaction, and their corresponding salts were prepared by a nucleophilic quaternization reaction at the nitrogen atom. Most of the synthesized ferrocenyl chalcone salts were soluble in water at room temperature. They were fully characterized by IR, NMR spectroscopy and HRMS spectrometry, and their electrochemistry was studied. The salt derivatives presented chemical reversibility, electrochemical quasi reversibility, and the slope of a plot of Log Ipc (or Ipa) versus Log v were almost 0.5 suggesting that their redox process was controlled by diffusion.
