This review explores the complex interactions of intrinsic and extrinsic mechanisms that regulate hair follicle stem cells and their role in skin homeostasis, aiming to advance understanding that could support future research on skin disorders.

This review explores the hormonal factors related to hidradenitis suppurativa, emphasizing insulin resistance and pro-inflammatory adipokines, but reports no new clinical findings and suggests further research is needed.

This study identified several genes highly expressed in germ-line stem cells that are also common in hematopoietic stem cells, potentially aiding the exploration of fundamental stem cell commonalities.

This study found that erosive pustular dermatosis of the scalp is often misdiagnosed as squamous cell carcinoma, highlighting the importance of biopsy for accurate diagnosis.

This study identified TSC2 as an important regulator of hair follicle morphogenesis and patterning, with Tsc2cKO mice showing altered hair patterns and frequencies compared to controls.

This study examined the dermoscopic features of five patients with tuberous sclerosis and found that dermoscopy can differentiate characteristic cutaneous features from similar conditions, potentially aiding in earlier diagnosis when other symptoms are subtle or absent.

This article introduces the ISHRS's Core Curriculum for Hair Restoration Surgery, detailing essential knowledge and techniques for physician competence in diagnosing and treating hair loss, without reporting new clinical results.

In a case report, this study identified a new genetic variant in a six-year-old girl from Saudi Arabia with hypotrichosis and juvenile macular dystrophy, expanding the understanding of the genetic spectrum of this rare condition in the region.

This study found that the cosmetic olfactory receptor agonist cyclohexyl salicylate may stimulate hair growth and expand stem cell progeny, suggesting potential as a cosmetic adjuvant for hair loss.

This article reviews various medical treatments for hidradenitis suppurativa based on the author's experience with over 350 patients, but it reports no new clinical findings.

This case report described a woman in her 40s with ulcerative scalp sarcoidosis presenting in atypical skin locations, diagnosed with systemic sarcoidosis following comprehensive examination and histological analysis, and experiencing improvement with prednisone and hydroxychloroquine treatment.

This study reports that in systemic sclerosis, CD34+ dermal fibroblasts transition to CD34−, podoplanin+, and CD90+ fibroblasts across the dermis, suggesting a role in unchecked fibrosis.

This study found that untreated hirsute patients have lower expression of type 2 17β-HSD mRNA in scalp hairs, indicating potential disturbances in androgen metabolism, compared to treated hirsute patients.

This study describes a family with loose anagen hair syndrome associated with macular dystrophy, suggesting this combination may represent a new disease entity among ectodermal dysplasias.

This study analyzed CADR reports in Singapore, finding nonsteroidal anti-inflammatory drugs, antibiotics, and iohexol frequently associated with serious skin reactions like rash and angioedema, with trends varying by demographics.

In this prospective case series, intralesional triamcinolone injections significantly reduced erythema, edema, suppuration, size, and pain in acute hidradenitis suppurativa flares, though the study's small size and design limit the findings.

This review discusses the role of heparan sulfate proteoglycans in regulating stem cell fate and highlights their potential as targets for addressing hair loss, without reporting new clinical results.

In this study, researchers identified that certain inflammatory cytokines, including osteoprotegerin and leukemia inhibitory factor, are inversely associated with hypertrophic scar risk, whereas others like CDCP1, GDNF, and PD-L1 show a positive association, suggesting potential pathways for intervention in scar formation.

This study reported that squamous cell carcinomas of the scalp can become extraordinarily aggressive, highlighting the need for early diagnosis and careful use of treatment strategies like wide excision and radiation therapy.

This case report of a 17-year-old with salt-wasting congenital adrenal hyperplasia due to 21-hydroxylase deficiency found that increasing the mineralocorticoid dose relieved daily headaches and reduced salt cravings.

This study found that mesenchymal stem cells sourced from hair follicle outer root sheath showed higher differentiation efficiency and angiogenic potential for vascular graft applications compared to adipose-derived stem cells.

This article discusses a strip donor harvesting technique for hair transplantation and reports no clinical results; the author highlights the importance of anatomical knowledge for successful scar excision.

This review discusses the potential of human induced pluripotent stem cells for regenerating hair follicles and developing cell-based therapies for hair loss, but it reports no new clinical results.

This paper reviews hidradenitis suppurativa, comparing its clinical and histopathological characteristics to acne, questioning the proposed link to terminal hair follicles, and reports no new results.

This review discusses the complexities of hidradenitis suppurativa pathogenesis, highlighting issues with Notch signaling, immune dysregulation, and the role of keratinocytes and ECM, but reports no new clinical results.

This review examines the potential of adipose-derived stem cells in disease treatment and highlights the need for further research to clarify their effectiveness and safety.

This study reports on a 46-year-old female with a high hairline who underwent hairline-lowering surgery using bone-tunneling suture fixation, achieving an average of 2 cm reduction, equivalent to transplanting up to 3,000 hair grafts, with satisfactory results for both patient and surgeons.

In this study, the researchers optimized the extraction conditions for crude polysaccharide from Hibiscus rosa-sinensis leaves, achieving a yield of 9.66% and demonstrated strong antioxidant activities in vitro.

This study established a murine chronic graft-versus-host disease model with scleroderma features, showing typical skin changes and cellular infiltrates associated with the condition.
