This chapter reviews trichoscopic criteria and diagnostic features for various hair and scalp conditions, emphasizing their utility in non-invasive diagnosis, but reports no new clinical results.

This study found that capillaroscopic patterns varied among patients with systemic scleroderma, psoriasis, psoriatic arthritis, and alopecia, suggesting potential microcirculation disturbances; however, no correlations were observed with serum angiogenic markers.

This review discusses spatial and temporal patterns in animals, focusing on skin appendage organs, but provides no new research findings.

This study shows that the Wnt-β-catenin pathway promotes TERT expression in both stem and cancer cells, linking tumorigenesis with pluripotency.

This study provides direct evidence that the Wnt-β-catenin pathway promotes TERT expression in stem and cancer cells, linking tumorigenesis with pluripotency.

In this study, researchers found that β-catenin directly promotes TERT expression in stem and cancer cells by interacting with the Tert promoter, illustrating a mechanistic link between tumorigenesis and pluripotency.

This report describes a rare case of pityriasis rosea-like eruption in a 52-year-old Thai woman following Oxford/AstraZeneca COVID-19 vaccination, emphasizing the condition does not preclude further vaccinations.

This review discusses the safety of dermatological medications used during pregnancy, highlighting that retinoids have strong teratogenic risks and should be used with caution; it reports no new clinical results.

Hair transplant surgery successfully restored a woman's pubic hair, improving her appearance and satisfaction.

In this case report, the authors detail a successful management of early scalp ischemia after hair transplantation using the FLOW protocol, which emphasizes cause correction, local vasodilation, oxygenation optimization, and wound care, resulting in recovery without necrosis.

In this case report, Triamcinolone Acetonide injections effectively improved mouth opening in patients with Oral Submucous Fibrosis, but both developed symptoms of Cushing's Syndrome, prompting the need for careful monitoring due to potential adverse effects when using this treatment.

Calcipotriol may effectively treat hair loss in alopecia areata, working better in children than adults.

New techniques and findings in dermatologic surgery show improved pain management, safer liposuction, better hair transplantation, and effective treatments for skin conditions.

Pilocarpin can cause hair regrowth and color change in some cases but not in others, and it may have side effects in animals.

This study observed that tributyltin pollution induces imposex, reduces reproductive success, and leads to population decline in Ocinebrina aciculata, highlighting its sensitivity compared to other prosobranch species.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.

This case report describes the first known association between maternal telogen effluvium and hair-thread tourniquet syndrome in infants, suggesting that informing new parents about hair loss may prevent toe tourniquet syndrome.

This study found no significant differences in sensation recovery or scar formation between radiofrequency and scalpel incisions in upper blepharoplasty, although radiofrequency caused greater tissue damage.

This paper examines crisis management models within sport marketing and sponsorship, focusing on the brand risks of athlete-triggered crises, and calls for further research in this area; it does not report new results.

This case report documents the second known instance of a salivary gland choristoma on the chest wall of a newborn, highlighting its benign nature and the importance of accurate diagnosis.

This review discusses various bioactive elements in cosmeceuticals, highlighting their potential benefits, such as anti-aging effects and skin tone improvement, while noting the growing demand due to safety concerns and expanding market opportunities.

This review provides an overview of microneedle-assisted photomedicine, detailing diagnostic and therapeutic strategies, design principles, and challenges for translating this approach to skin disease management.

This study suggests that noninvasive carboxytherapy methods, like gel formulations and device-assisted delivery, can significantly improve skin conditions with high safety and no recovery time, particularly in sensitive areas.

This article describes a case of pilomatricoma in a 22-year-old male with successful surgical excision and no recurrence, highlighting its histopathological features and typical clinical presentation.

This study found a severe MBTPS2 gene mutation in a Japanese IFAP syndrome patient, suggesting other factors may influence the syndrome's clinical features compared to previously studied patients.

This observational study reports a striking correlation between the use of henna hair dye and a specific pattern of hair loss, termed "hennapecia," but calls for experimental research to determine causality.

This research highlights that engineered mice lacking the vitamin D receptor show multiple health issues similar to human vitamin D deficiency, underscoring the widespread impacts of the vitamin D endocrine system.

This review discusses the potential of single cell technologies to improve understanding and treatment of impaired wound healing and reports no new clinical results.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.
