A narrative review on asthma and pest sensitization (cockroach, mouse and rat allergens): a social issue besides the medical problem.

Objective: Among animals defined as "pests", cockroaches and rodents (mouse and rat) represent the most common cause of airway allergic sensitization and bronchial asthma worldwide. Their frequency of sensitization has been widely assessed in US and other countries but poorly in Western Europe. This narrative review aims to provide a synthesis of data resulting in MEDLINE concerning allergic sensitization/asthma to pests as well as their related environmental/social risk factors, specifically in the European area.

Use of face masks and allergic nasal symptoms: Why not mention pollen count and air pollution data?

The scientific quantification of symptoms in pollen-related allergic rhinitis cannot be separated from the aerobiological data of the geographical area in which the study was carried out.

Anxiety and depression in adolescents with asthma and in their parents. Is an increased basal cholinergic tone a possible further reason to explain the negative impact on asthma control?

To the Editor We read with interest the excellent article of Licari et al.  reporting that anxiety and depression are common in adolescents suffering from asthma as well as in their parents, mainly in mothers. The consequence of this relationship is that emotional disorders might negatively affect also the control of asthma.

Psychological Stress, Lung Function and Exacerbation Risk in COPD: Is an Increase of Cholinergic Tone a Possible Link?

at a glance: On the hypothesis that psychological distress might interfere with airway reactivity in patients suffering of mild to moderate COPD through a cholinergic-mediated-bronchial reflex.

Critical aspects in dog allergen immunotherapy (DAI). May Component Resolved Diagnosis (CRD) play a role in predicting the efficacy?

We hypothesize that a pivotal condition determining the efficacy of dog allergen immunotherapy (DAI) might be the mono-sensitization to dog lipocalins (Can f 1-2) in individuals not directly or indirectly exposed to other furry animals. In fact, the concomitant sensitization to lipocalins and/or albumins, especially in those patients directly exposed to furry animals, may potentially stimulate patient's airways by inducing persistent inflammation and, thus, clinical symptoms. In these conditions, it is likely that DAI alone could be inadequate to reduce airway inflammation mediated by inhalation of dog allergens in patients with simultaneous exposure to other furry animals.

Anaphylaxis and intimate behaviour.

Purpose Of Review: Intimate behaviours may represent an unusual way of exposure to a culprit allergen, or the frame for sex-related allergies due to triggers typically linked to that situation. The present review aims at summarizing the state of the art about the topic, in order to spread the awareness and the basic know-how in the field of sexual-related allergies.

Recent Findings: Kiss-related IgE-mediated reactions are caused in sensitized partners mainly by the passive transport of allergenic molecules through saliva, skin or oral mucosa.

Can bronchial asthma with an highly prevalent airway (and systemic) vagal tone be considered an independent asthma phenotype? Possible role of anticholinergics.

Recently, we studied occurrence and role of non-respiratory symptoms (n-RSs) before a worsening of asthma symptoms. Some n-RSs such as anxiety, reflux, heartburn, abdominal pain, which appeared within 3 h before the onset of an asthma attack, are the likely result of an imbalance between sympathetic/parasympathetic systems with an increase in cholinergic tone. Therefore, it is likely that some of these n-RSs induced by the increased cholinergic tone might be present related with specific parasympathetic-associated respiratory symptoms such as those elicited by airway narrowing.
