Diagnostic delay due to COVID-19 pandemic: a case of uncontrolled growth of peripheral giant cell granuloma

COVID-19 pandemic had several consequences including reduced access to public health care service that led to significant delays in screenings, diagnosis, and treatments. Peripheral giant cell granuloma (PGCG) is a benign exophytic lesion of reactive nature, affecting gingiva and alveolar ridge. Recent studies report its highest prevalence in 5th-6th decade of age, occurring mainly in mandible with an average size of 1.3-1.7 cm. We aimed to show the impact of pandemic on diagnosis delay in a patient with peripheral giant cell granuloma that reached unusual dimensions. ACaucasian 61-year-old male referred to our observation for the presence of an exophytic lesion on edentulous alveolar crest of the mandible. He was an edentulous patient, that developed a lesion of unusual dimensions of 7x4.5x3.5 cm. The soft consistency, slow exophytic growth and bluish-red color suggested an inflammatory hyperplastic nature of the lesion. An excisional biopsy was performed in association with curettage of underlying periosteum. Histological examination revealed presence of spindle-shaped mononuclear cells and multiple multinucleated giant cells in a well vascularized stromal tissue. No calcifications were found. Clinical and histological features suggested the diagnosis of PGCG. This case is clinical evidence of the delays induced by the COVID-19 emergency, which negatively affected all health care and suggests that the PGCG, albeit benign in nature, may have an uncontrolled and non-self-limiting growth, making its surgical removing and healing process more complicated.

Alteration of the perception of cold, heat and texture of food in association with taste dysfunction in COVID-19

COVID19 is characterized by alteration of smell and taste perception. It was investigated the presence of alteration for cold, heat, and food consistency perception in COVID-19 patients and the possible correlation with the most commonly used biomarkers in a routine way (CRP, IL-6, IL-1, PSP, PCT) to show if the local inflammatory process may induce alteration of cold, heat, and food consistency perception in COVID-19. From March 2020 to April 2021, a survey about taste and oral tactile/thermal sensitivity dysfunction was carried out on 1155 patients with mild or moderate COVID-19, while patients admitted to intensive care were excluded because they could not answer questions from health professionals. Positive RT-PCR confirmed all diagnoses. CRP, IL-6, IL-1, PSP, and PCT were detected for each patient. Taste and Smell Questionnaire Section of the US NHANES 2011−2014 protocol (CDC 2013b) was used for gustatory function assessment. The study was approved by the Ethics committee of AOU Policlinico Consorziale di Bari (No. 6388 COVID19 DOM-protocol number 0034687/12-05-2020), and written informed consent was obtained. A total of 208 patients referred only to alteration to taste (208/821). 75/208 ageusia, 71/208 ipoageusia, 21/208 fantageusia, 19/208 dysgeusia, 22/208 parageusia. Significant correlations between CRP, IL-6, IL-1, PSP, PCT levels and type of dysfunctions about the perception of heat, cold and food consistency have not been found (P>0.05). Loss of taste can be due to the action of inflammatory mediators on gustatory buds, while alteration of cold, heat and food consistency perception may be due to direct damage of filiform papillae, allowing virus binding through the spike protein to ACE2 receptors of filiform papillae cells.

The integumentary system and its microbiota between health and disease.

The aim of the present investigation was to evaluate the essential physiological functions of the skin microbiota in human health and diseases. The main characteristics of the normal microbiota in the different anatomical sites have been reported in relation to the main factors, such as the effect of age, on its composition and stability for the eubiosis condition. Moreover, the present overview analyzed the functions and composition and the correct functionality of the skin microbiota in the light of current knowledge. According to several evidence is important preserving the eubiosis of the commensal microbes of the microecosystem (symbiotic and pathogenic), and probiotics are able to counteract the conditions of dysbiosis. Also, it has been shown that there is a crosstalk between gut and skin microbiota that affects human health and is still being studied, and its relationship to the current pandemic SARS-CoV-2.
