Objective: To study the impact of age and the interval between disease diagnosis and death on the organotropism of SARS-CoV-2.
Method: Patients underwent post-mortem biopsies from lungs, Waldeyer ring, heart, liver, kidneys and bone marrow between 2020‒2021. SARS-CoV-2 organotropism was mapped by using molecular RT-PCR analyses for SARS-CoV2 targeting the Envelope gene (E), the RNA Polymerase Gene (RdRp), and the Nucleocapsid gene (N).
The aim of this manuscript is to show the surgical technique for horizontal supraglottic laryngectomy in T3 carcinomas by a transoral approach using microelectrodes and radiofrequency. From 2009 to 2020, 11 selected cases of T3 laryngeal supraglottic carcinomas invading the pre-epiglottic space, with preserved vocal cords mobility underwent surgery. The technique is described step by step.

Introduction: The histological study of nasal polyps does not reveal any specific lesions but eosinophilic infiltration nasal mucosae seems to be characteristic of nasal polyposis. The aim of this work is to study possible links between certain histological and clinical aspects in nasal polyposis. Furthermore, we attempt to compare the quantification of tissue eosinophilia according to the number of eosinophils per field with the percentage figure obtained with respect to the total of inflammatory cells.

Objective: This study compared the acute tissue damage produced by a CO2 laser and microelectrodes in samples of vocal cords from patients undergoing laryngeal endoscopic surgery for stage T1 squamous cell carcinoma.
Study Design And Setting: Based on prior surgical experience with the CO2 laser and microelectrodes, the study protocol used hematoxylin-eosin staining of vocal cords treated with a CO2 laser (n=20) or microelectrode (n=20).
Results And Conclusion: The acute tissue damage produced by the CO2 laser was similar to that induced by microelectrodes in cutting mode.
