This study found that Sp6 overproduction in ameloblast-lineage cells increased cell proliferation and ameloblastin expression, suggesting that Sp6 promotes amelogenesis by inhibiting follistatin gene expression.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This source reports that the JOLT technique using HA fillers is effective in lifting and tightening the lower face and neck, camouflaging the jowl, and improving marionette lines and the mandibular border.

In this case report, localized myxedema of the scalp was identified in a patient with Graves disease and Hashimoto thyroiditis, emphasizing the varied skin manifestations in autoimmune thyroid conditions.

In this case report, successful management of a pituitary macroadenoma was achieved with thyroid hormone therapy, leading to reduced tumor size and improvement in symptoms like galactorrhea and headaches.

In this study, combining hair transplantation with platelet-rich plasma was found to be more effective than hair transplantation alone in reducing hair loss, improving hair regeneration, and decreasing skin lesions in patients with androgenic alopecia.

This study found that facial rejuvenation with fat grafting around the prejowl sulcus provided better improvement in jowling and had fewer adverse effects compared to mandibular ligament release without fat grafting.

This study found that osteopontin expression was significantly higher in alopecia areata lesions compared to healthy controls, suggesting it may play a role in the disease's pathogenesis.

This review examines the causes and characteristics of androgen excess in postmenopausal women, but reports no new clinical results; the authors emphasize challenges in diagnosis and potential long-term health impacts.

This case report describes a 61-year-old female with hyperandrogenic symptoms, where an ovarian hemangioma with stromal luteinization was identified and surgically removed, resulting in improved symptoms.

This study found that a high-fat diet in rats led to obesity, insulin resistance, and structural changes in the parotid salivary glands, with associated negative impacts on general health.

This study found that GAGS scores for acne were higher in younger women with PCOS and a lower BMI, but showed no association with levels of androgen hormones.

This article reviews the role of androgens in male pattern hair loss and its emotional impact, but reports no new clinical findings.

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 case report describes an infant with mucopolysaccharidosis type II who developed generalized hypertrichosis after receiving a bone marrow transplant and cyclosporine, highlighting the medication's potential role in exacerbating excessive hair growth and reviewing hypertrichosis causes.

This study found that while hyaluronic acid fillers can enhance facial balance and aesthetics, particularly in the temple area, they carry significant risks like vascular occlusion and blindness, highlighting the need for careful technique and product selection to ensure safety.

This case report describes a Thai male with TRPS1 who exhibited unique and unreported features such as hypoplastic mandibular condyles, double mental foramina, and distinctive hair abnormalities.

This study reports that hydrocortisone ointment significantly improved eyebrow erythema and hair growth in a 10-year-old with ulerythema ophryogenes.

This article outlines hypertrichosis lanuginosa, emphasizing its rarity, potential congenital or acquired nature, association with malignancy, challenges in diagnosis, limited treatment options, and the need for more research to understand its mechanisms.

The woman's symptoms and tests suggest her adrenal glands are producing too many male hormones.

This case report describes a 52-year-old black woman with diffuse scalp swelling and thinning hair attributed to a large increase in the thickness of scalp subcutaneous fatty tissue.

This report describes two cases of postoperative alopecia following oral surgery, highlighting potential risk factors such as head positioning and prolonged operative time, and suggests prevention strategies.

This study found that menstrual irregularity is common in women with acromegaly, with high GH levels, estrogen deficiency, and larger tumors correlating with more severe irregularity.

This study found no evidence of increased keratinocyte proliferation in acne vulgaris, suggesting that other mechanisms may be responsible for hyperkeratinization in acne pathogenesis.

Hyperandrogenism in women often causes acne and excess hair, treatable with lifestyle changes and medications.

This case report illustrates that Leydig cell tumors, despite causing significantly elevated androgen levels, can be difficult to localize due to their small size, as demonstrated in a 42-year-old woman whose tumor was only identified after oophorectomy.

This letter to the editor presents two new cases of traumatic panniculitis with localized hypertrichosis and provides clinical considerations, but it does not report experimental findings.

This review discusses acquired hypertrichosis lanuginosa, a rare disorder often linked to internal malignancy, and reports no new clinical findings; the authors highlight proposed pathogenic mechanisms for lanugo hair overgrowth.

In this study, researchers used 3D printing combined with cryogenic crosslinking to develop gelatin/oxidized alginate scaffolds and found that adding 5% hydroxyapatite improved mechanical properties and osteogenic effects, enhancing bone tissue regeneration, though 10% hydroxyapatite offered no additional osteogenic benefits and reduced shape fidelity.

This study found that serious complications were more likely after using muscle-only free flaps for skull coverage compared to composite flaps.
