ReviewDermatologic Symptoms and Syndromes Associated with Headache.
Headache disorders are often accompanied by associated symptoms involving organ systems other than the central and peripheral nervous system, including the integumentary, cardiovascular, and musculoskeletal system. However, skin changes or conditions are not commonly associated with headache disorders. Recognition of possible etiologies of headache in patients with bruising, rash, or neurocutaneous disorders can help guide workup and management. The purpose of this article is to review the various dermatologic presentations associated with headache. ⋯ Multiple review articles and retrospective studies have noted the association between head pain with dermatologic changes including ecchymoses, inflammatory skin conditions, and neurocutaneous disorders. Postulated mechanisms include activation of the trigeminal autonomic system and involvement of similar pro-inflammatory molecules. In this review, we discuss three different classes of rashes including ecchymoses, inflammatory skin conditions, and neurocutaneous disorders, all of which have been associated with migraine and/or headache. We discuss the possible underlying pathophysiology and treatment options.

Summarization and comparison of dermoscopic features on different subtypes of rosacea.
The dermoscopic features of rosacea have already been reported. However, the current findings are incomplete, and little is known about phymatous rosacea. Hence, this study aimed to summarize and compare the dermoscopic features and patterns of three rosacea subtypes (erythematotelangiectatic [ETR], papulopustular [PPR], and phymatous [PHR]) in the Chinese Han population and to evaluate whether these features differ with patients' genders, ages, and durations. ⋯ The dermoscopic patterns of ETR are red diffuse structureless areas and reticular linear vessels. For PPR, the pattern comprehends combinations of red diffuse structureless areas, reticular linear vessels, yellow scales, follicular plugs, and follicular pustules. Meanwhile, PHR is characterized by remarkable orange diffuse structureless areas, linear vessels with branches, perifollicular white color, orange focal structureless areas, and white lines.

Rosacea is a common cutaneous condition affecting predominantly the face. It is historically characterised into four subtypes: erythematotelangiectatic, papulopustular, phymatous and ocular rosacea. This article describes the pathophysiology, clinical features and current treatment options for rosacea, and discusses updated diagnostic criteria. ⋯ Erythema should be treated with brimonidine tartrate gel, oral medication such as beta blockers or vascular laser and light-based therapy. Oral doxycycline 40 mg modified release can be used as monotherapy or in combination with other treatments for recalcitrant disease. Further understanding of the pathogenesis of rosacea could allow identification and targeted avoidance of triggers and the development of new treatment modalities.

Rosacea is a facial chronic inflammatory skin disease with immune and vascular system dysfunction. Paeoniflorin (PF) is a traditional Chinese medicine with anti-inflammatory properties. However, its effects on rosacea remain unknown. ⋯ These changes could be abrogated by SOCS3 siRNA in vitro. In conclusion, the pathogenesis of rosacea involves abnormal macrophage infiltration within the lesions. PF inhibits the macrophage-related rosacea-like inflammatory response through the SOCS3-ASK1-p38 pathway, demonstrating its potential application as a novel drug for rosacea therapy.

Rosacea has been linked to inflammatory bowel disease and small bowel bacterial overgrowth. We aimed to investigate the fecal microbial profiling and the potential gene functions between rosacea and non-rosacea subjects. ⋯ An altered fecal microbial richness and composition were observed in rosacea patients. The distinct microbial composition might be related to sulfur metabolism, cobalamin and carbohydrate transport.
