KLF4 is important for maintaining skin stem cells and helps heal wounds.

A boy with chromosome 13q deletion syndrome developed eye cancer, a woman with breast cancer lost vision due to a rare side-effect of her treatment, a man's vision worsened after using a hair loss drug, and two rare disorders were discussed. Optical Coherence Tomography is useful for diagnosing and monitoring these conditions.

Using defensins to activate stem cells may improve skin aging signs without causing inflammation.

Colchicine can inhibit hair growth by affecting cell activity and protein expression in hair follicles.

Platelet-rich plasma might help with skin aging, ulcers, and hair loss, but more research is needed to prove its effectiveness and safety.

Many treatments for hair loss lack proper testing and FDA approval, so their effectiveness is uncertain.

Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.

Non-immune factors play a significant role in alopecia areata.

The type 3 IP3 receptor is important for controlling hair loss and growth.

A new triple drug system using nanoparticles effectively targets breast tumors in 3D models.

Wait 3 months after COVID-19 before trying assisted reproduction and further research is needed on COVID-19's effects on male hormones and fertility.

The enzymes 5α-reductase and 3α/β-hydroxysteroid oxidoreductase help create brain-active substances from progesterone and testosterone, which could be used for treatment, but more research is needed to ensure their safety and effectiveness.

Chemotherapy and cytokine therapy can cause various skin reactions, including hair loss and hypersensitivity.

COVID-19 may harm male fertility and damage the reproductive system.

Nanostructured lipid carriers are promising for improving drug delivery in medicine and food.

The new FDA labeling rules provide more detailed drug safety information for pregnant and breastfeeding women, but more data is needed on the risks of many dermatologic drugs.

Certain genetic markers linked to reproductive potential were identified by their impact on a protein's ability to bind to genes.

Over 50% of women over 50 experience hair loss, with minoxidil being the only proven effective treatment.

COVID-19 and hypopituitarism (reduced pituitary gland function) are linked, with the latter's related health issues potentially worsening COVID-19 outcomes, and COVID-19 possibly increasing risk for pituitary complications.

Blocking enzymes that help the virus enter cells could be a promising way to treat COVID-19.

Cardiovascular drugs can cause various skin problems, so recognizing these reactions is important.
