This study reports that intralesional triamcinolone acetonide was effective and well-tolerated for treating extensive alopecia areata in patients who often showed specific initial hair characteristics.

This case report highlights an atypical presentation of vitamin B12 deficiency in a 28-year-old man with reversible symptoms including localized hand hyperpigmentation and megaloblastic anemia, resolved after B12 supplementation.

This study describes tumor necrosis factor inhibitor-associated psoriatic alopecia, highlighting the distinctive histologic feature of sebaceous lobule atrophy, which is potentially reversible and helps differentiate it from idiopathic psoriatic alopecia.

In this study, topical application of the SCD1 inhibitor XEN103 significantly reduced sebaceous gland size and number in mouse skin, suggesting potential local therapeutic effects for acne treatment without systemic side effects.

This study found that prolonged inhibition of DGAT1 in mice and dogs led to atrophy of sebaceous glands, with mice also experiencing alopecia, suggesting potential skin-related risks for humans using DGAT1 inhibitors.

This review discusses the effects of mineralocorticoid receptor overexpression in mice skin, reporting no new data but highlighting its link to epidermal atrophy, early barrier formation, eye issues, and hair loss.

This retrospective study found that intralesional betamethasone injections led to significant repigmentation in scalp vitiligo patients without leukotrichia, suggesting it as an effective treatment option.

In this study, detailed examinations of alopecic lesions in two female Cronkhite-Canada syndrome patients suggested hair regrowth might occur without systemic corticosteroids if not required for gastrointestinal treatment, and hair loss may begin with anagen-telogen transition.

This quiz based on a Journal of Investigative Dermatology article reports no new clinical results but serves as an educational tool for diagnosing scalp conditions, including scalp psoriasis and psoriatic alopecia.

In this study, beagle dogs treated with hydrocortisone 17-butyrate 21-propionate ointment showed various toxic effects, including acne-like skin changes and organ atrophy, which returned to normal after a recovery period.

Zinc deficiency causes reversible hair loss by disrupting hair growth and stem cell function.

This case report observed that a 20-year-old female with recurrent DVTs experienced reversible alopecia with various anticoagulants, except fondaparinux which allowed long-term treatment without this side effect.

The authors concluded that Lrig1-positive stem cells are essential for sebaceous gland formation in mice, as their ablation led to temporary sebaceous gland disappearance without affecting hair growth.

In this study, Lrig1-positive stem cells in mouse hair follicles were found to be essential for sebaceous gland formation and maintenance, with their depletion causing a temporary loss of these glands and changes in cellular differentiation.

Finasteride temporarily lowers male rat fertility without affecting libido.

In this case report, azathioprine induced sudden hair loss and pancytopenia in a 42-year-old female patient, but discontinuing the drug and providing supportive care resulted in complete recovery and hair regrowth within 2.5 months.

Kennedy's disease leads to muscle weakness without a cure, but exercise and managing symptoms may help patients live a normal lifespan.

This study investigated a patient with spinal and bulbar muscular atrophy who had 68 CAG repeats, revealing early onset and unique symptoms not previously documented in the condition.

A woman's unique dementia was misdiagnosed, a genetic mutation increases Parkinson's risk with age, and finasteride may help with Tourette syndrome.

This study found that stem cells derived from spinal and bulbar muscular atrophy patients exhibited reduced androgen receptor levels and HDAC6, providing potential insights into the disease mechanism for future therapies.

The authors reviewed the mechanisms behind Kennedy's disease, noting advances in therapeutic strategies such as androgen deprivation and gene silencing that may soon expand treatment options for this incurable neuromuscular condition.

This study highlights that adverse effects from finasteride may persist in men after discontinuation, indicating a potential "post-finasteride syndrome.

This case report describes a hemodialysis patient whose hair loss reversed after switching from tinzaparin to enoxaparin, suggesting tinzaparin-induced alopecia.

This article discusses Kennedy's disease, detailing its genetic cause, symptoms, and diagnostic criteria, but reports no new clinical findings and highlights a lack of causal therapy.

This article discusses nutritional contributions to hair health and highlights the need for identifying risk factors for deficiencies but reports no new clinical findings.

This report describes two cases of VKH disease and SO where severe alopecia, likely due to incomplete treatment, improved following systemic steroid therapy.

This article discusses laboratory and physical markers that may help detect androgenic anabolic steroid abuse in athletes and reports no new primary research results.

This review discusses topical calcineurin inhibitors for cutaneous lupus erythematosus and reports no new clinical findings; the authors emphasize the need for more comparative studies with corticosteroids.

This study attempts to classify histomorphologic reactions to drugs to aid in diagnosing drug eruptions, which are common in hospitalized patients but lack specific diagnostic features.

This chapter discusses hypothyroidism in dogs, highlighting that most cases are due to primary thyroid gland issues and that some breeds may have a hereditary predisposition; it reports no new clinical findings.
