Over the recent years development toward assessing skin sensitization hazard has moved toward non-animal testing methods. These methods are based on the key events as described in the OECD Adverse Outcome Pathway (AOP) for skin sensitization initiated by covalent binding to proteins. As these individual methods address mainly one mechanistic event (key event) in the initiation of skin sensitization, combination of different methods are needed to conclude on the skin sensitization hazard. Validated and regulatory adopted (EU and OECD) in chemico/in vitro methods are available for KEs 1-3 and are presented here. This chapter also illustrates how individual test methods can be combined by providing two examples of defined approaches to testing and assessment for skin sensitization hazard identification and assessment.

Inhaled and intranasal corticosteroids are widely used in the management of allergic respiratory diseases. Delayed drug hypersensitivity reactions to budesonide are a rare adverse drug reaction characterized by non-immunoglobulin E (IgE)-mediated clinical manifestations, including localized or systemic contact dermatitis, mucosal edema, and paradoxical worsening of pre-existing symptoms. However, such reactions are often underdiagnosed due to atypical presentations.

Animal allergens, particularly those from cats, dogs, and horses, are significant risk factors for the development of allergic diseases in childhood. Managing animal allergies requires allergen avoidance and, when this is not feasible, specific immunotherapy. Patient history remains the cornerstone of diagnosis, providing the foundation for diagnostic algorithms.

Achieving UVA/B-selective, skin-inspired nociceptors with perception and blockade functions at the single-unit device level remains challenging. This is because the device necessitates distinct components for every performance metric, thereby leading to complex preparation processes and restricted performance, as well as the absence of deep UV (UVB and below)-selective semiconductors. Here, to address this, we develop a structure-simplification skin-inspired nociceptor using a reverse type-II CuAgSbI/MoS heterostructure.

This letter offers constructive feedback of the study by Sağun et al. on changing allergen sensitivity in the COVID-19 pandemic. The data presented were very interesting concerning the changing rates of sensitization, but the authors neglected some important areas requiring further consideration.

Objective: The present study aimed to preliminarily explore the temporal summation (TS) response to repetitive mechanical stimulation in patients with temporomandibular joint disorders (TMD).
Patients And Methods: Twenty patients with unilateral pain in the TMJ and 20 gender- and age-matched healthy controls were included. A modified Quantitative Sensory Testing (QST) protocol was performed including pressure pain thresholds (PPT), mechanical pain thresholds (MPT), and numerical rating scale (NRS) scores of TS effects of 10 repeated 0.
