A gene mutation worsens skin irritation in mice due to a lack of certain fats.

A chemical called 5-Bromo-2′-deoxyuridine caused rapid hair loss in mice by killing certain skin cells through a specific cell death pathway.

The document concludes that understanding nail anatomy is key for diagnosing nail diseases, early signs of nail melanoma may allow for less aggressive treatment, and specific genetic mutations are important in thyroid cancer prognosis and treatment.

Non-scarring hair loss can be diagnosed with two 4mm punch biopsies, one cut vertically and the other transversely.

RET mutation is important in familial medullary thyroid carcinoma, and BRAF mutation in papillary thyroid carcinoma is linked to more aggressive cancer and higher death rates.

Early subungual melanoma might be treated with less aggressive surgery because it invades the skin under the nail more slowly.

Human scalp hair follicles have PGE2 and its receptors, which might affect hair growth.

Tretinoin gel is safe for sun exposure, but tacalcitol doesn't significantly improve non-segmental vitiligo.

The document concludes that treatments like oral anti-androgens, minoxidil, and topical spironolactone can be effective for hair loss in men and women.

PCOS is a complex condition with major health impacts, needing more research for better diagnosis and treatment.

Most women with excess male hormones have Polycystic Ovary Syndrome, and hormonal therapy can improve symptoms but may cause side effects.

Chemotherapy in the first trimester of pregnancy is risky, but in the second and third trimesters, it's generally safe with careful drug selection and timing.

Melatonin affects many body functions beyond sleep by interacting with specific receptors in various tissues.

The document concludes that non-binary individuals need compassionate support and recognition in healthcare, without being pathologized.
