This review suggests that isotretinoin's effects on severe acne and various cancers may result from apoptosis, which might also explain its adverse effects through genetic variability.

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.

In this study, finasteride doses as low as 0.2 mg per day significantly reduced both scalp skin and serum DHT levels in men with androgenetic alopecia.

This study reported that Malassezia-associated dermatitis can cause pruritus in cats with feline paraneoplastic alopecia.

This review discusses the association between androgen receptor CAG repeat polymorphism and several health conditions, including Kennedy’s disease and urologic disorders, without reporting new clinical results.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

This review discusses the cutaneous manifestations associated with HIV infection, highlighting that these skin conditions often present atypically and are more severe compared to those in non-HIV-infected individuals; it reports no new clinical findings.

In this study, BLIMP1 was found to function in terminally differentiated epidermal cells to maintain homeostasis, rather than defining a sebocyte progenitor population.

This study found that four days of simulated night shift work in healthy adults reduced insulin sensitivity, suggesting a potential increased risk of type 2 diabetes.

Dupilumab may cause hair loss in some patients with severe atopic dermatitis.

In this study, contaminated drinking water in Dakahlyia governorate was linked to health issues like hair loss, renal failure, and liver cirrhosis, attributed to industrial and agricultural pollutants.

This study found that finasteride at 1 mg/day was the most effective dose for treating male pattern hair loss, with similar efficacy to 5 mg/day and better results than lower doses.

This article reviews sex disparities in COVID-19 outcomes and explores the influence of sex hormones on disease severity, but it reports no new results; further studies are ongoing.

Apremilast was not effective in treating moderate-to-severe alopecia areata.

This study presents the first reported case of woolly hair nevus appearing during adolescence, with significant improvement observed 5 years later and structural changes in the hair documented.

This study found that microRNA levels in hair shafts were significantly decreased in scleroderma patients compared to normal subjects, suggesting they may serve as effective biomarkers.

In this study, researchers found that hepatitis C virus infection is a significant risk factor for sporadic porphyria cutanea tarda, suggesting familial cases might be more prevalent in areas with low hepatitis C infection rates.

This study evaluated the effect of 2% ketoconazole lotion for androgenetic alopecia, but the results regarding its effectiveness on clinical appearance remained unclear.

In this study, a modified Ferriman-Galwey score greater than 4 was found to be effective for diagnosing hirsutism in Asian women, highlighting key areas such as the upper lip, thighs, and lower abdomen.

This case report describes a male patient with aromatase deficiency, revealing that a c.628G>A mutation can lead to varied clinical features, such as low bone mass and normal metabolic profiles.

This study found that deleting the CD98hc protein in mouse skin impairs wound healing and homeostasis, resembling aging effects, due to disrupted integrin signaling pathways.

This study observed that patients with pemphigus have a higher incidence of hypothyroidism, inflammatory bowel disease, and diabetes compared to the general population.

Iron deficiency is not a significant cause of hair loss in women.

This article reviews trichoscopic signs of chemotherapy-induced alopecia, including exclamation marks, but reports no new clinical results.

This study discusses the immune dysregulation observed in individuals with Down syndrome, highlighting their increased risk for autoimmune skin conditions, but does not yet clarify the molecular mechanisms behind this profile.

In this study, an endoscopic midface lifting technique showed notable improvement in midface ptosis and infraorbital hollowing, with lower morbidity and few complications after over 400 procedures.

This study identified several compounds from traditional Chinese medicines that may inhibit prostaglandin D2 synthase, potentially providing promising candidates for treating androgenic alopecia with minimal adverse skin reactions.

This review discusses immune pathways involved in alopecia areata and explores emerging, more targeted therapeutic strategies, noting their potential for better safety and effectiveness compared to traditional immune suppressants.

In this study, women with polycystic ovary syndrome had significantly higher lipocalin-2 levels compared to controls, suggesting it may be a useful marker for insulin resistance in this population.

This review highlights the potential for clinicians to recognize skin manifestations as a straightforward method to detect insulin resistance and improve management of diabetes and obesity.
