Biocides are chemicals used as preservatives added to most cosmetics and toiletries and to industrial water-based products such as cutting fluids, paints and glues. There are numerous biocide formulations used in water-based metalworking fluids. All these products, characterized by a low molecular weight, can react with endogenous proteins and may induce allergic contact dermatitis. Thus, numerous reports on occupational allergic contact dermatitis have been published. The purpose of this experimental study was to compare the sensitizing potential of the various classes of biocides used in metalworking fluids by means of the maximization test of Magnusson & Kligman. The results show that, from the 9 samples tested, 7 biocides induced sensitization varying in grade from moderate to strong, while 2 benzisothiazoline-based samples did not induce allergic contact dermatitis.

Background: Doxepin (DX) is used orally to relieve itching but can cause side effects like blurred vision, dry mouth, and drowsiness due to its antimuscarinic effect. To reduce these adverse effects and improve skin permeation, DX is being developed in topical formulations. This study aims to improve DX skin absorption by developing a microemulsion (ME) formulation (ME-DX).

Purpose: To investigate the changes in meibomian gland (MG) structure in allergic conjunctivitis (AC) patients using an intelligent quantitative analysis algorithm and to explore the relationship between these changes and clinical parameters.
Methods: A total of 252 eyes from patients with AC and 200 eyes from normal controls were examined. Infrared meibography was performed using the non-contact mode of the Keratograph 5M.
