Current Views about the Inflammatory Damage Triggered by Bacterial Superantigens and Experimental Attempts to Neutralize Superantigen-Mediated Toxic Effects with Natural and Biological Products.

Superantigens, i.e., staphylococcal enterotoxins and toxic shock syndrome toxin-1, interact with T cells in a different manner in comparison to conventional antigens.

Facial masks vestibulitis: the risk of mismanagement in the COVID-19 pandemic.

The COVID-19 pandemic has forced the global population to adopt several public health measures, including social distancing, environmental disinfection and use of personal protective equipment (PPE), which are still widely recommended although several vaccines are currently available. Dermatological and allergological diseases related to the extended use of the PPEs represent an emerging problem amidst the pandemic. In particular, there are increasing reports of skin damage, occupational dermatoses, Irritant Contact Dermatitis (ICD) and allergic contact dermatitis (ACD) related to surgical facemasks and N95.

Eosinophilic lingual tonsillitis induced by sublingual immunotherapy: A case series.

The new observation of eosinophilic lingual tonsillitis as a possible adverse reaction to sublingual immunotherapy is likely to stimulate new investigations aimed at improving the understanding of the mechanisms of biodistribution of extracts placed at the sublingual level.

The Human Respiratory System and its Microbiome at a Glimpse.

The recent COVID-19 pandemic promoted efforts to better understand the organization of the respiratory microbiome and its evolution from birth to adulthood and how it interacts with external pathogens and the host immune system. This review aims to deepen understanding of the essential physiological functions of the resident microbiome of the respiratory system on human health and diseases. First, the general characteristics of the normal microbiota in the different anatomical sites of the airways have been reported in relation to some factors such as the effect of age, diet and others on its composition and stability.

An unusual foreign body in the upper aerodigestive tract: esophageal obstruction due to bran impaction.

Foreign bodies of the upper aerodigestive tract are common problems encountered by the otolaryngologist and general surgeons. While the diagnosis seems straightforward, it is sometimes delayed until after serious complications have occurred. The treatment of choice is endoscopic retrieval under general anesthesia.

Major salivary gland diseases. Multicentre study.

This multicentre study involved 28 Italian ORL Centres responding to a questionnaire sent by us which allowed recruitment of a high large number of cases of parotid neoplasms observed over a 10-year period. Statistical data obtained partly confirmed previous findings. Benign tumours account for 80% of case histories with a relationship 1:4 M/F, the most frequent being pleomorphic adenoma (57.

[Nutritional problems in the surgical patients with head and neck tumours. Literature review and personal experience].

During the last years the importance of the correct nutritional assessment as a part of the therapeutic process of the human pathologies has a greatly increased relevance. Still more in oncology, such relationship among nutritional assessment and good result of the therapeutic treatment have a fundamental importance. Among the neoplastic diseases those of the head and the neck result to be particularly aggressive, both for their nature and for the particular anatomical organization of such body areas, and the affected patients also need a precise evaluation of the nutritional assessment to obtain an optimal therapeutic result.

[Objective evaluation of dysphonia. Possibilities and limitations].

Today clinical evaluation of the presence and extent of dysphonia is still essentially based on subjective-perceptive criteria. The lack of objectivity and the one-sidedness of such an approach reinforces the desire for a quantitative, objective determination of dysphonia which could aid in making an modern, unequivocal evaluation of the presence, extent and variations in time of this disorder both upon onset and after treatment. The purpose of the present research was to determine the reliability, possibilities and limitations of an objective, parametric procedure to evaluate both the normal and pathological voice.

[Carcinoma of unknown origin++ with latero-cervical metastasis. Diagnostic problems. Retrospective analysis of 110 cases of latero-cervical tumefaction].

The cervical region, despite to its little extension, is very important by the surgical and anatomical point of view. This region, occupied by a lot of organs, sometimes is the site of metastasis from carcinomas located in various parts of the body. In some cases the origin site of cancer stays unknown.

[Virtual reality: a simple joke or therapeutic instrument?].

Virtual reality is a relatively new application for rehabilitative neurology, and achieve many successes in assessment and treatment of CNS damages. The Authors describe a prototype computer simulation for virtual environment reconstruction to assess the fundamental living skills of every day dedicated to persons in which CNS injury was occurred.
