This review explores the biomechanical factors and signaling systems, like Wnt, involved in the pathophysiology of psoriatic nail lesions and reports no new results.

This study found that restoring hypothalamic NPY levels in mice delayed aging-related characteristics such as fat loss, hair loss, and memory decline, suggesting that maintaining these levels could be important for counteracting aging and its effects.

This study utilized magnetic resonance imaging to noninvasively visualize and differentiate skin structures in rat skin, finding a significant correlation between MRI data and histological areas.

This study found that a ceramide derived from sphinganine can bind to African–American hair, reducing breakage when applied in a shampoo after relaxing treatments.

This study found that red ginseng extract may stimulate hair growth in a mouse model by enhancing dermal papilla cell proliferation and activating skin antioxidant defenses.

This study assessed breeding value estimation methods for Korean Sapsaree dogs, finding varied accuracy across BLUP approaches and identifying significant genomic regions affecting traits like body height and hair length. The researchers suggest these findings can enhance breeding strategies for this culturally significant breed.

This narrative review concluded that facial aging involves complex anatomical changes that require multimodal rejuvenation approaches, integrating fillers, collagen stimulators, botulinum toxin, and energy-based devices for effective results, while emphasizing the need for scientific evidence and patient safety in aesthetic treatments.

In this study, researchers demonstrated that self-assembled gold nanoclusters with aptamers effectively deliver anti-NFκB aptamer drugs to inhibit hair follicle regeneration while being non-toxic to normal cells, offering a targeted treatment for hypertrichosis.

This case series found that low-frequency repetitive transcranial magnetic stimulation may benefit some patients with trichotillomania, although one of five patients experienced worsening symptoms after treatment.

This study found that children with repetitive respiratory tract infections had significantly lower levels of the trace elements zinc, iron, and copper in their hair compared to healthy children.

This study concluded that low-level fluence 810 nm diode laser therapy was generally well tolerated, safe, and effective for long-term hair reduction in a small sample of patients with various skin types.

This article discusses body-focused repetitive behaviors like trichotillomania and excoriation disorder, noting their higher prevalence than previously thought and the importance of dermatologic and psychiatric assessment in treatment; it reports no new clinical results.

This review highlights that obsessive-compulsive disorder and body-focused repetitive behaviors are increasingly encountered in dermatology, often going undetected, and emphasizes the role of dermatologists in early identification and interdisciplinary treatment to address both physical and psychological aspects for improved outcomes.

This study highlights a complex link between hair care and HFRBDs and suggests that personalized hair care strategies could improve condition management and be integrated into professional guidance by clinicians and hair experts.

This case report documents a rare instance of body-focused repetitive behavior in a 37-year-old male physician who compulsively pulled hair from his thighs due to exam stress, highlighting the variability in presentation and demographics of such disorders and the potential for psychiatric comorbidity.

In this case report, a 47-year-old man experienced systemic hair loss after starting hemodialysis, which resolved after discontinuing the antipruritic drug nalfurafine, suggesting its role in causing hair follicle capillary regression.

This study found that adding rose hip extract to permanent wave solutions increased wave effectiveness and reduced hair damage, although variations in hair type may affect the results.

This study suggests that fibroblast growth factors FGF-4, FGF-8, and FGF-9 may play redundant roles as signals in epithelial-mesenchymal interactions during multiple stages of tooth development in mice.

This review examines the existing research on pathologic hairpulling, skin picking, and nail biting, suggesting these behaviors are underrecognized and may benefit from a unified diagnostic categorization; it reports no new clinical findings.

This article reviews the psychiatric conditions associated with HIV, highlighting the bidirectional relationship and management challenges but presents no new research findings.

This article proposes a new classification, the Obsessive-Compulsive Insight Continuum, to help dermatologists better understand and diagnose skin disorders with obsessive-compulsive features.

In this study, individuals with body-focused repetitive behaviors reported increased symptoms during the COVID-19 pandemic, highlighting the psychological impact of pandemic-related societal changes on this population.

This study reports increased instances of trichotillomania-related hair loss in young girls during the COVID-19 pandemic, which may be linked to social isolation and school closures.

This case series describes young men with mild scalp psoriasis and a family history of androgenetic alopecia who exhibit a compulsive behavior of preserving scalp scales, highlighting a potential body-focused repetitive behavior.

This study found that repetitive 532 nm laser therapy significantly decreased scores for macules, pigmented, and vascular lesions on the facial area, regardless of skin phototype or age.

In this case study, repetitive botulinum type A toxin injections led to almost complete resolution of severe chronic pain in a patient with Parry-Romberg syndrome.

In this study, repetitive subcutaneous administrations of a conditioned medium from stem cells significantly suppressed hair graying in mice exposed to X-ray irradiation, likely through antioxidative mechanisms involving HGF and potentially VEGF.

This study found that mice lacking the type 3 IP(3) receptor in their hair follicles experienced repetitive hair loss and regrowth, indicating disrupted hair-cycle regulation potentially linked to specific signaling pathways.

This research highlighted that AI-assisted surgical robots could significantly enhance surgical precision and efficiency by analyzing patient data, making real-time decisions, and automating repetitive tasks, thus potentially improving patient safety and surgical outcomes.

This study found that reduced hair samples showed higher protease degradation than permed hair, which increased with repetitive perming, and degradation was influenced by the type of mercaptan used.
