This review discusses the complex causes and treatment challenges of chronic inflammatory skin diseases, emphasizing the need for biomarkers to predict treatment responses; it reports no new clinical results.

This study reports that oral spironolactone may be a useful and low-cost first-line treatment for hidradenitis suppurativa in women, with relatively few side effects.

This review examines various treatments for dissecting cellulitis, noting isotretinoin may offer the best chance for remission despite limited long-term data and calls for more clinical studies.

This study found that most patients with folliculitis decalvans showed improvement and remission with oral antibiotics, although some experienced relapses and required prolonged treatment.

This guideline outlines therapies for hidradenitis suppurativa/acne inversa, noting that oral tetracyclines, clindamycin, and surgical options are important for treatment, with adalimumab, secukinumab, and bimekizumab also approved.

This study examined the therapeutic response to folliculitis decalvans treatments among 60 patients and found that earlier disease onset was linked to more severe cases, while a combination of rifampicin, clindamycin, tetracyclines, and intralesional steroids was most effective in controlling symptoms.

In this case study, a 55-year-old woman with androgenetic alopecia was ultimately diagnosed with hepatic cortisone reductase deficiency after initially suspected 21-hydroxylase deficiency was ruled out.

This study suggests that daughters of women with PCOS may have altered androgen metabolism in early childhood, with increased 5α-reductase activity potentially contributing to PCOS development.

This study observed that 70.7% of patients with frontal fibrosing alopecia stabilized with treatment, and patients using 0.3% tacrolimus were more likely to stabilize in 3 months compared to other treatments.

This review summarizes various drug treatments for hidradenitis suppurativa, noting their effectiveness, side effects, and high recurrence rates, but reports no new clinical findings.

This review discusses the side effects and diseases related to hairstyles and hair treatments among black women, highlighting the need for thorough examination by dermatologists, but reports no new clinical results.

This article presents a case study of a 25-year-old man with persistent scalp nodules and abscesses with patchy alopecia, unaffected by a course of oral tetracycline.

This case study describes a pregnant woman who developed a pruritic rash with follicular lesions containing yeast-like organisms, resistant to conventional acne treatments.

This study found that topical application of niacin derivatives significantly increased hair fullness in women with female pattern hair loss compared to a placebo after six months.

This case report describes a patient with frontal fibrosing alopecia experiencing significant hair regrowth and reversal of cutaneous atrophy after treatment with the 5α-reductase inhibitor finasteride.

This article discusses the efficacy and safety of mycophenolate mofetil and hydroxychloroquine for treating lichen planopilaris and reports no new clinical results.

This study found that recombinant hepatitis B vaccine may increase the risk of alopecia areata onset in older predisposed mice but larger trials suggest this effect might lie within normal variation.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

In this study, thread-embedding therapy enhanced hair regrowth in C57BL/6 mice by regulating growth factors associated with hair follicle anagen development and promoting cellular proliferation in hair follicles.

This review discusses recent findings on the epigenetic regulation of adult stem cells and cancer stem cells, highlighting shared and distinct features, and reports no new clinical results.

Women with PCOS have higher 5α-reductase activity, which may be linked to insulin resistance.

This study reports that generalized discoid lupus erythematosus is a recognized canine variant of cutaneous lupus erythematosus, resembling its human counterpart, with varied treatment responses and common relapses.

This review discusses the cutaneous side effects of chemotherapy, noting that they frequently involve changes to skin, hair, and nails, and reports no new results.

This review indicates that many former FDA category D and X systemic dermatologic medications may negatively impact male fertility, with further research needed to assess potential teratogenic effects.

EGFR cancer drugs often cause a rash, which can lead to distress and isolation, but may also improve outcomes for some cancer patients. Current treatments for the rash are limited, but a compound called menadione shows promise.
