Purpose: To study the long-term efficacy and safety of local application of imiquimod 5% and fluorouracil 1% creams in complex eyelid basal cell carcinomas (BCCs). Methods: A retrospective, non-comparative study in biopsy-proven, complex (involving canthi or >50% of eyelid length) eyelid BCC patients who were medically unfit for surgical procedures. All patients were medically treated with either of the creams using fixed-dose regimens for a minimum of 3 months. All received oral vitamin C 500 mg QID for 3 months as an adjunct for collagen healing. A minimum of “post-treatment” follow-up of 12 months was observed. Results: Of total 30 patients, imiquimod 5% and fluorouracil 1% were used in 16 and 14 patients, respectively. The mean age of our patients was 70.5 years. The co-morbidities included – severe coronary artery disease using blood-thinners ( n = 19), poorly controlled diabetes ( n = 12), poorly controlled hypertension ( n = 6), on nebulization ( n = 3), and tuberculosis with pulmonary fibrosis ( n = 2). Complete clinical tumor resolution was noted in 10 and 8 patients over 12 and 16.5 weeks, respectively, in imiquimod and fluorouracil groups. Periocular skin erythema, chemical conjunctivitis, and skin depigmentation were seen in all the patients of imiquimod group. On the other hand, the local side-effect profile in fluorouracil patients was limited. Conclusion: The medical treatment of complex eyelid BCC is a useful alternative to surgery in the elderly with significant co-morbidities. It provides a promising long-term relief with a tolerable side-effect profile. A prospective, randomized, double-blinded trial would provide stronger evidence for the efficacy of these drugs.

Olfactory receptors (ORs) are expressed and active in various human tissues, including the skin. Although the sense of smell plays an important physiological role in the regulation of mood and stress, a link between olfactive compounds, ORs, and skin stress has yet to be established. This study aims to investigate the role of newly identified skin ORs and agonists in the modulation of skin stress. Screening for odorant molecules was done with cAMP functional assay to identify OR agonists. RT-qPCR and immunofluorescence microscopy were conducted to identify and quantify ORs in epidermal keratinocytes (NHEKs) and human skin explants, as well as to evaluate specific markers (G6PDH, loricrin, and γH2AX) of stress-induced skin alterations. A randomized double-blinded, split-face clinical study was performed on a panel of stressed women to measure the benefits of OR agonist treatment for skin. Three new ORs (OR10A6, OR2AG2, and OR11H4) were identified in skin. A specific Rose extract and its major constituent (phenylethyl alcohol) were found to activate these ORs. The extract composition was revealed by both GC/FID and GC/MS analyses simultaneously and showed the presence of 34 volatiles molecules. Moreover, epinephrine induces a skin stress response characterized by increased expression of G6PD, loricrin, and γH2AX biomarkers, and a decrease of OR expression. These effects were prevented in the presence of rose extract and its benefits were confirmed clinically by a decrease in the appearance of under-eye dark circles. Altogether, our findings suggest that ORs may represent a new, promising way to treat stress-associated skin disorders.
