Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is typically characterized by Type 2 inflammation. Several biomarkers of eosinophilic inflammation, including Galectin-10, also known as Charcot-Leyden crystal protein (CLCP), have been identified to establish eosinophilic infiltration of polyps, a reliable predictor of recurrence. We aimed to evaluate the Galectin-10 expression in nasal polyps of patients with CRSwNP and to assess the correlation of Charcot-Leyden crystals expression to the severity of CRSwNP according to Clinical-Cytological Grading (CCG).

Methods: A double-label immunofluorescence was performed to evaluate the expression of Gal-10, CD15, Tryptase, and CD63 and their eventual co-localization on histological samples of 18 patients with CRSwNP. Double-positive Gal-10+CD15+ and Galectin-10+Tryptase+ inflammatory cells were counted by confocal microscopy.

Results: Galectin-10 was detectable in all examined tissues from CRSwNP patients, and its expression increased as low, medium and high CCG tissues were examined, respectively. Galectin-10 was extensively present in inflammatory cells, while limited Galectin-10 deposits were detected around mucosal epithelial cells.

Conclusion: We showed the strong correlation between CCG and Galectin-10 expression, mainly colocalized with infiltrating eosinophils and mast-cells, in patients affected by CRSwNP.

Surgical mask and N95 in healthcare workers of Covid-19 departments: clinical and social aspects.

Acta Biomed 2020 11 10;91(4):e2020171. Epub 2020 Nov 10.

University of Foggia.

Introdution. In order to prevent or slow down the transmission of COVID-19, various public health measures have been introduced, including social distancing, environmental disinfection and the use of personal protective equipment (PPE). In this perspective, the clinical practice of healthcare professionals has changed dramatically. As a matter of fact, the use of surgical masks and N95 has significantly worsened the job performance of workers who deal directly with COVID-19 disease.

Methods: The study included 116 health workers employed in the pulmonology, intensive care and infectious diseases departments of Bari and Foggia Hospital, directly involved in the healthcare of patients affected by COVID-19. Between May 1, 2020 and May 31, 2020, each participant completed an online questionnaire aimed to investigate the impact of the COVID-19 pandemic on workers' lifestyle changes and job performances. We compared the results based on the type of mask used by each participant (surgical mask vs N95).

Results: Although disturbances related to the use of the mask arose earlier in subjects who wore the N95 (p = 0.0094), healthcare workers that wore surgical masks reported a statistically higher average score for a greater number of disorders.

Conclusions: This is the first study that compares the effects of the two most used PPE on the quality of life of health workers and which highlights the greater discomfort caused by surgical masks. This result brings to light a serious social problem, being surgical masks widely used in everyday life by ordinary people and non-healthcare workers.
