This review discusses drug-induced hypersensitivity syndrome and drug reaction with eosinophilia and systemic symptoms, highlighting clinical features, potential viral reactivations, and treatment, but reports no new clinical findings.

This study found that scanning electron microscopy revealed considerable abnormalities in hair morphology in MPS I, II, IIIA, and IIIB patients, potentially related to heparan sulfate accumulation.

This study found that individuals with heterozygous truncation-type variants in the *DSP* gene exhibit lower skin temperature and higher transepidermal water loss, with specific microscopic skin changes and pseudomonilethrix.

This study found that a dopamine-methacrylated hyaluronic acid hydrogel enhances the efficacy of adipose-derived stem cells in promoting skin regeneration, potentially involving the Notch signaling pathway.

"D-CHRAMPS syndrome" is a newly identified condition with multiple severe symptoms.

This source reports that a study by Liu et al. analyzed genetic factors influencing adalimumab response in hidradenitis suppurativa, finding a specific genetic variant (SNP rs59532114) associated with an inadequate response to the treatment due to increased abscess and inflammatory nodule counts.

This review discusses the use of human mesenchymal stem cells (hMSCs) for treating skin diseases and suggests they show promise for improving conditions like wounds and scleroderma, but more research is needed due to varied study designs and endpoints.

This study suggests that in hidradenitis suppurativa, MMP-induced matrix alterations may contribute to inflammation by releasing active peptides and inflammatory factors in the extracellular matrix.

In this study, researchers found that human adipose tissue-derived mesenchymal stromal cells exhibit significant phagocytic ability against various particles and pathogens, which might enhance strategies for addressing specific local and systemic infections due to their regenerative properties.

Patients with Shwachman-Diamond syndrome often get misdiagnosed due to a wide range of symptoms, including immune system problems and bone abnormalities.

In this study of clinical-grade ADMSCs, researchers found that cells expanded in PowerStem MSC1 media exhibited increased negative marker expression, chromosomal abnormalities, and signs of senescence compared to those cultured in StemMACS MSC Expansion Media, suggesting that the latter is more suitable for therapeutic applications.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This study found that Hataedock may alleviate atopic dermatitis symptoms in mice by maintaining skin homeostasis and improving skin barrier formation through the endocannabinoid system.

This study showed that exosomes from hyaluronic acid-primed induced mesenchymal stem cells promote hair growth by enhancing proliferation and migration of hair follicle dermal papilla cells and modulating key growth factors and signaling pathways, potentially counteracting the effects of DHT-induced hair loss.

This article presents an overview of uncombable hair syndrome, emphasizing its clinical and molecular characteristics and noting systemic manifestations such as neuropsychiatric, ophthalmic, and cardiopulmonary issues.

This study reported that mSKPs and DMSCs share similarities in biological characteristics but exhibit distinct transcriptome profiles, with mSKPs being more immune-related and DMSCs more associated with differentiation and disease pathways.

This case report describes regression of hidradenitis suppurativa lesions in two patients after 16 weeks of adalimumab treatment.

This study suggests that StemMACS MSC Expansion Media is more suitable than PowerStem MSC1 media for expanding therapeutic adipose-derived mesenchymal stem cells, with less expression of negative markers and better chromosomal stability.

This study found that despite challenges, a combination of oral antibiotics, anti-androgens, oral retinoids, biologics, and surgery were important in managing hidradenitis suppurativa in patients with intellectual and developmental disabilities.

This study found that human mesenchymal stem cells overexpressing JAM-A improved hair follicle structure and hair formation in mice by reducing abnormalities such as curved and zigzagged follicles.

This study suggests that human induced pluripotent stem cells can be used to generate dermal papilla equivalent cells, potentially aiding hair follicle regeneration and drug discovery for hair diseases.

This case study details the successful treatment of macrophage activation syndrome with dexamethasone and cyclosporine in a 36-year-old woman with adult-onset Still's disease, highlighting the critical importance of timely aggressive treatment.

This study found that exosomes from hyaluronic acid-primed mesenchymal stem cells may promote hair growth in androgenetic alopecia by improving hair follicle cell function and restoring key signaling pathways disrupted by DHT.

This study found pathogenic mutations in genes EDA, EDA1R, and EDARADD in 101 out of 124 hypohidrotic ectodermal dysplasia patients, revealing 23 novel mutations and indicating genetic variability.

This commentary suggests that mesenchymal stem cells (MSCs) should be redefined as "master signaling cells" due to their primary role in regulating tissue homeostasis and regeneration through signaling functions.

In this study, mutations in the CDH3 gene were identified as the cause of hypotrichosis with juvenile macular dystrophy, and the researchers observed substantial phenotypic variability among affected individuals.

This article reviews the potential relationship between serum amyloid A and hidradenitis suppurativa, highlighting genetic influences, but reports no new clinical findings.

This case report describes an instance of autosomal recessive uncombable hair syndrome caused by maternal uniparental disomy of chromosome 1.

This study developed immortalized human hair follicle-derived mesenchymal-like stromal cells (iHF-MSCs) as a consistent source of therapeutic secretome, reporting their superior immunomodulatory and regenerative performance, potentially advancing cell-free therapies for inflammation and tissue repair.

This systematic review identified robust biomarkers associated with hidradenitis suppurativa and confirmed potential drugs for repurposing, highlighting key pathogenetic pathways and their links to comorbid disorders.
