In this retrospective study, 60.9% of patients with alopecia areata responded to superficial hypothermic cryotherapy, with effectiveness notably higher when the treatment interval was 2 weeks or less, particularly in early disease stages, and minimal side effects were observed.

Children with alopecia areata often face more stress and depression, especially related to separation, which can affect their condition.

This case report highlights that alopecia areata can mimic syphilitic alopecia in patients with recent or active syphilis, emphasizing the importance of trichoscopy in accurately diagnosing alopecia types and preventing misdiagnosis.

This literature review highlights challenges in managing alopecia areata in the Middle East and Africa, noting significant regional gaps in data, treatment guidelines, and public awareness that impede patient care and emphasize the need for improved support and resources.

This study observed that patients with rapidly progressive alopecia areata may have a favorable prognosis regardless of treatment, and regenerated vellus hairs were linked to higher improvement or cure rates.

This meta-analysis found that alopecia areata patients had significantly higher serum levels of IL-6 and TNF-α compared to healthy subjects, indicating a potential role of these cytokines in the condition's pathogenesis.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.

In this study, nail changes, particularly pitting, were associated with moderate to severe cases of alopecia areata and a positive family history, highlighting potential genetic factors in the condition.

This review discusses the effects of photobiomodulation, particularly its potential to reduce inflammation in various conditions, but it does not report new clinical findings.

This article reviews the clinical presentation and histopathologic features of alopecia areata and proposes a hypothesis for its development, but it reports no new clinical results.

This article reviews the epidemiology, clinical evaluation, and pathogenesis of alopecia areata and highlights recent advancements, but it does not report new clinical findings.

This study identified collagen XXII as a novel extracellular matrix protein specifically present at tissue junctions, where it functions as a cell adhesion ligand for skin epithelial cells and fibroblasts.

This research overview highlights that although JAK inhibitors show promise as potential treatments for alopecia areata based on recent insights into the disease mechanism, their efficacy has not yet been thoroughly evaluated in a systematic manner.

In this study, platelet-rich plasma significantly increased hair regrowth and reduced symptoms of alopecia areata compared to triamcinolone acetonide or placebo, with no observed side effects.

This review discusses alopecia areata as a model for studying tissue-directed autoimmune diseases and reports no new clinical findings.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

This study observed that autologous platelet-rich plasma treatment improved hair count and density in areas with androgenetic alopecia compared to placebo, with differing outcomes based on the PRP collection device used.

This study observed that alopecia areata can be induced and serially transferred in C3H/HeJ mice using skin grafts, providing a useful model for studying the disease in humans.

This review noted that alopecia areata is an autoimmune disease impacting hair follicles and offered insights into its complex pathogenesis involving immune responses, while highlighting ongoing research into new treatments such as Janus kinase inhibitors and other immunomodulatory drugs.

In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.

This study developed an animal model that recreates alopecia areata by injecting healthy human skin grafts in immunocompromised mice with peripheral blood mononuclear cells enriched for NKG2D+ and CD56+ cells.

This article reviews treatment options for male-pattern and female-pattern hair loss, telogen effluvium, and alopecia areata, but provides no new clinical results; algorithmic management approaches are included.

In this study, researchers reported that a keratinocyte growth factor-Ig fusion protein could specifically detect and localize KGFRs in epithelial tissues, suggesting a method for histochemical detection of growth factor receptors.

This study found that patients with alopecia areata had higher levels of Th17 cells and lower levels of regulatory T cells compared to healthy controls, suggesting an immune imbalance in these patients.

This study suggests that CD8+ cytotoxic T lymphocytes play a crucial role in the development of alopecia areata, based on observations in rodent models that mimic human autoimmune disease.

This review discusses the psychological impact of alopecia on women and reports no new clinical findings, highlighting the effect on self-esteem and quality of life.

The document explains different types of hair loss, their causes, and treatments, and suggests future research areas.

This study demonstrated the expression of type 1 interferon-related proteins in inflammatory lesions of alopecia areata, showing a distinct distribution pattern compared to cicatricial alopecia.

This article reviews the classification, diagnosis, and management of hair disorders, emphasizing the role of trichoscopy and early diagnosis for effective treatment but reports no new clinical findings.

This review discusses the variety of skin disorders associated with atopic dermatitis, exploring their complex relationships and shared genetic and environmental factors, but reports no new clinical results.
