Regenerative medicine and its offshoot, regenerative aesthetics, have been hot topics over the past 15  years. Studies with heterochronic parabiosis and others pointed to a circulating factor that could rejuvenate aging tissues. Stem cells are known to have regenerative powers, but they are difficult to extract, grow in culture or maintain. Exosomes (EVs), extracellular vesicles from 30 to 150 nm, have been discovered to be a primary form of communication between tissues. Using stem cell supernatants to generate desirable EVs has become a heralded treatment for aesthetic treatments. Preclinical studies with EVs show many benefits including improving the function of fibroblasts and healing wounds more rapidly. Clinical studies with EVs in aesthetics are very few. Thus, the excitement generated by EVs should be tempered with realism about the lack of available treatment products as well as the lack of scientific proof.

ABSTRACT

Background: Rubber additives are common causes of allergic contact dermatitis (ACD) worldwide, yet data from Turkey remain

Objectives: To evaluate the prevalence of rubber additive sensitisation and its clinical/occupational relevance in a tertiary re ferral centre.

Methods: A retrospective study on 2687 consecutively patch-tested patients with rubber additives at our allergy unit between 1996 and 2023.

Results: Rubber sensitisation was found in 10.6%, with a slight increase after 2010. Male predominance was noted (female: male=1:2.3). Thiurams and carbamates were the most frequent sensitizers. ACD was diagnosed in 7.9%, primarily caused  by gloves (85.5%). Hands were most commonly affected (94.4%). Logistic regression analysis showed that thiuram and carba mate sensitisation was significantly associated with hand eczema, while benzothiazole derivatives were linked to foot eczema. Airborne ACD occurred in 4.2%, mainly in healthcare workers. Hand eczema with and without wrist extension was observed with similar frequency. Occupational ACD accounted for 79.3% of cases, especially among construction (56.8%) and healthcare workers (14.8%), with a relative increase in the latter group after 2015.

Conclusions: The high prevalence of sensitisation from rubber gloves is concerning. Legal measures are urgently needed, includ ing safer additives and clearer glove labelling. Patch testing remains essential, even without the classic glove-pattern distribution.
