This study analyzed skin biopsies from human monkeypox virus (hMPXV1) cases and found characteristic pustular stage features, including epidermal necrosis, shadow cell appearance, ballooned keratinocytes, and a dense inflammatory infiltrate, expanding histological knowledge crucial for understanding this disease and related Orthopoxvirus infections.

This study reported that tail tip lesions in dairy cows include granulation tissue, purulent-necrotizing inflammation, and hyperkeratosis, potentially caused by ischemia.

This study observed that hair follicle morphology in dairy cows changes during the peripartum period, with fluctuations in hair follicle width and anagen percentage but no overall marked changes in skin morphology parameters.

This study found that melatonin, when administered to Wistar rats prior to and after radiation exposure, reduced oxidative stress markers and histopathological damage in skin tissue compared to radiation alone, suggesting it may effectively prevent and treat radiation-induced skin injury.

Continuous light exposure in rats leads to PCOS-like symptoms and suggests sleep habits might affect the disorder's development.

In this study on Iranian patients with non-scarring alopecia, researchers found that androgenetic alopecia was the most common subtype, with perifollicular inflammation observed more in males. They reported that transverse sectioning is generally sufficient for diagnosis, but combining with vertical sectioning provides more comprehensive information.

This review proposes that inconsistent findings in androgenic alopecia research are due to variable biopsy location, hair diameter diversity, and hair follicle miniaturization, and suggests ways to improve study methods.

In a case study of vitamin D-dependent rickets type 2A, researchers observed that while active vitamin D treatment failed to improve bone and laboratory abnormalities, oral calcium lactate significantly ameliorated these issues, although skin and hair problems remained unresponsive.

This study observed that the COVID-19 pandemic was associated with changes in skin condition patterns among Iraqi females, with significant increases in hair loss and decreases in certain viral infections.

Researchers found a new mutation in the HR gene causing hair loss and skin bumps in a Pakistani family.

This study found that dissecting cellulitis of the scalp was more common in young men, with an association between longer disease duration and increased severity, but no link between age and severity.

This Delphi consensus study provides expert insights into hair aging, aims to enhance diagnostic precision and management of age-related hair changes, and identifies possible new therapeutic targets.

Lichen planopilaris and frontal fibrosing alopecia are likely distinct diseases with different tissue involvement.

This study found increased infiltration of specific immune cells, such as γδ T cells and CD8+ T cells, in the bald scalp of male androgenetic alopecia patients, and identified four key immune-related genes potentially involved in hair loss development through interferon-γ signaling pathways.

This study found that a high dose of epidermal growth factor induced hair loss in sheep by causing apoptosis in anagen hair and transitioning the hair cycle to catagen.

In this study, subcutaneous injection of bone marrow mesenchymal stem cells in burned rats significantly improved wound healing by reducing inflammation, scar formation, and wound size, and restoring normal skin structures.

In this study, NAC was observed to counteract the negative effects of cyclophosphamide on hair follicles in mice, preserving both biochemical parameters and hair structure, suggesting its potential as a therapeutic option for chemotherapy-induced hair loss.

This article reports on three new cases of Birt–Hogg–Dubé Syndrome and emphasizes the role of genetic analysis in its diagnosis due to clinical challenges.

This study found that Malassezia folliculitis, common among young adult males, can be distinguished from truncal acne by its clinical features and responds well to antifungal treatment.

In this study, oral care products like foams and a spray, similar to tap water, improved salivary pH and oral clearance rates after exposure to Coca-Cola® in young adults, but no significant differences were found between these products and tap water.

This study identified discoid lupus erythematosus and pseudopelade of Brocq as the leading causes of scarring alopecia, highlighting the importance of skin punch biopsy for accurate diagnosis.

This study observed that the COVID-19 pandemic influenced patterns of skin and venereal diseases among Iraqi females, with some conditions like hair loss increasing, while others like viral infections decreased.

This study found that female pattern hair loss in Saudi women was associated with lower hematological parameters and serum ferritin levels, suggesting iron deficiency may contribute to the disease.

This study found that trichoscopy was 73.77% concordant with histopathology in diagnosing patchy alopecia, highlighting its usefulness as a diagnostic tool for conditions like alopecia areata, lichen planus pigmentosus, and discoid lupus erythematosus.

In this mouse study, the researchers found that the monoclonal antibody ME1 causes hair follicle inflammation by up-regulating TNFα, which can be reduced by TNFα and interleukin-1 inhibitors.

This article proposes renaming frontal fibrosing alopecia to frontal fibrosing alopecia syndrome to better reflect its varied presentations and enhance understanding and treatment approaches.

This study found that in SAMP8 mice, phenotypic changes in outer hair cells or the stria vascularis, possibly due to oxidative deficiencies, may predict variability in age-related hearing loss before outer hair cell loss occurs.

This review discusses various skin reactions after SARS-CoV-2 infection and COVID-19 vaccination, noting a higher incidence with mRNA vaccines than adenovirus vector vaccines, and reports no new clinical results.

This study found that scalp melanoma often occurs in areas with androgenetic alopecia, and patients without alopecia might experience a later diagnosis due to hair coverage, leading to potentially worse outcomes.

This study found that combining ASA with conditioned medium from adipose tissue-derived MSCs may offer a promising approach for protecting against hippocampal injuries, suggesting potential synergistic therapeutic benefits that merit further investigation.
