Harlequin syndrome in a young girl: An opportunity to rethink the terminology.

Harlequin syndrome is a rare disorder of the autonomic nervous system, presenting as unilateral reduced flushing and sweating of the face induced by exercise, stress, or heat. It is caused by a cervical sympathetic deficit located at the preganglionic or postganglionic level on the non-flushing side. We present a case of an 8 year old with harlequin syndrome and review the other dermatological conditions for which the term "harlequin" is part of the nomenclature.

The Association of Various Metabolic Parameters with Multiple Skin Tags.

Background: Skin tags (STs) are benign skin lesions. Their definite etiology remains unknown. We aim to examine the association of obesity, diabetes mellitus, hyperlipidemia, thyroid abnormalities, acanthosis nigricans, and multiple STs in a Greek primary population. Methods: Phototype and body weight were recorded. Fasting serum blood samples were analyzed for cholesterol, low-density lipoprotein, high-density lipoprotein, triglycerides, glucose, and thyroid-stimulating hormone. Univariate ordinal logistic regression multivariate analysis was performed. Results: The univariate analysis showed that patients who were overweight with Fitzpatrick Skin Type III, acanthosis nigricans, and hypothyroidism were more likely to present with multiple skin tags as compared with patients at a normal weight with Skin Type I. Statistically significant associations were also found with the presence of cholesterol and triglycerides. In the multivariate analysis, a significant association between hypercholesterolemia and STs was demonstrated. Those with skin tags were more likely to have hypothyroidism. Conclusion: STs are often associated with obesity. An association between lipid profile and STs has been reported. Multiple STs have been independently associated with acanthosis nigricans. Although a possible relationship between STs and thyroid disease has not yet been proved, our review reveals a possible trend. Future investigations with larger sample sizes might clarify the association between skin tags and hypothyroidism.

Combination of microneedling and 10% trichloroacetic acid peels in the management of infraorbital dark circles.

BACKGROUND: Dark circles (DC), seen in the periorbital area, are defined as bilateral, round, homogeneous pigmented macules whose aetiology is thought to be multifactorial. Available treatments include bleaching creams, topical retinoic acid, chemical peels, lasers, autologous fat transplantation, injectable fillers and surgery (blepharoplasty). OBJECTIVE: To evaluate the efficacy and safety of a combination of microneedling and 10% trichloroacetic acid (TCA) peels in the treatment of DC. MATERIALS AND METHODS: Thirteen female patients with mild to severe infraorbital DC were included in the study. The patients were aged between 21 and 61 years. They were treated with Automatic Microneedle Therapy System-Handhold and topical application of 10% TCA solution to each infraorbital area for five minutes. The effect was photo-documented and a Patient and Physician Global Assessment was evaluated. Safety was assessed by evaluating early and delayed adverse events. RESULTS: Almost all patients showed significant aesthetic improvement. Both Physician and Patient Global Assessment rated a fair, good or excellent response in 92.3%. The procedure was well tolerated. Mild discomfort, transient erythema and oedema were quite common during or immediately after the procedure. The patients were followed up regularly every month for four months, and no recurrence was recorded. CONCLUSION: Microneedling and 10% TCA constitute an innovative combination treatment for DC with encouraging results and minor side effects.
