Hydrogen peroxide and viral infections: A literature review with research hypothesis definition in relation to the current covid-19 pandemic.

We reviewed the literature concerning the innate response from nasal and oral epithelial cells and their reaction to hydrogen peroxide (HO). Hydrogen peroxide is produced physiologically by oral bacteria and plays a significant role in the balance of oral microecology since it is an important antimicrobial agent. In the epithelial cells, the enzyme superoxide dismutase catalyzes a reaction leading from hydrogen peroxide to the ion superoxide.

Identification and Characterization of Nasal Polyposis and Mycoplasma Superinfection by Scanning Electron Microscopy and Nasal Cytology with Optical Microscopy: A Case Report.

Nasal polyposis is characterized by benign, non-cancerous and painless growths originating in the tissue of the nasal cavities and paranasal sinuses. Polyps arise from chronic inflammation due to asthma, recurrent infections, allergies, drug sensitivity or immune disorders. They can obstruct the nasal cavities and thus cause respiratory problems, a reduction in the sense of smell and susceptibility to infections.

Nasal and systemic eosinophilia associated with solid intestinal tumors, a case report and review of the literature.

The authors report the study of a clinical case, which presented eosinophilia both in the secretion of the nasal mucosa and in the blood count. After a careful examination of all the pathologies related to hypereosinophilia, through a clinical study, they have documented the presence of an adenocarcinoma located in the ileocecal junction of the colon. From what has been documented it is clear that only a clinical observation of precision, carried out above all through nasal cytology and colonoscopy, is able to diagnose an important pathology, such as oncology.

Relationship between gastroesophageal reflux disease and Ph nose and salivary: proposal of a simple method outpatient in patients adults.

Introduction: The frequency of gastroesophageal reflux disease (GERD) is increasing, in part through easy inspection of the upper digestive tract, but especially for a real spread of the disease as a consequence of modernity, lifestyle, incorrect dietary rules, and stress arising from social norms. It is a common chronic gastrointestinal disorder in Europe and the United States.

Materials And Methods: The aim of our study is to highlight a relationship between gastroesophageal reflux disease and salivary pH as evidenced by indicator strips, especially in the outpatient field.

Cytological aspects on the effects of a nasal spray consisting of standardized extract of citrus lemon and essential oils in allergic rhinopathy.

In this paper, a new formulation of nasal spray was set up based on the extract of lemon pulp, obtained by using a new solid-liquid technology of extraction, added to pure Aloe juice, soluble propoli, and essential oils of Ravensara and Niaouly. It was tested in a clinical study in which 100 subjects were recruited for a period of one month. Nasal scraping was used for collecting samples and after the application of the May-Grünwald Giemsa standard technique, glass slides were analysed by using optical microscope with a 1000x oil immersion.

Pietro Anzolino da Eboli and the thermal therapy of renal pathologies.

In the Campi Flegrei area of Campania, a region of Southern Italy, some thermal baths still exist, known for the therapeutical properties of their waters. Utilized since remote ages for the treatment of a variety of pathologies. In "De Balneis Terrae Laboris", an Italian poet of the Middle Ages and scientist, Pietro Anzolino da Eboli, reports every detail about more than thirty different thermal sites in the Campi Flegrei, including all therapeutic effects of their waters.
