Horizontal scalp biopsy sections are better for diagnosing alopecia areata, showing fewer hair follicles and more miniaturized hairs.

MicroRNAs are crucial in controlling cell signaling, affecting cancer and tissue regeneration.

Finasteride, often used for hair loss, can potentially cause cataracts.

A baby boy with 13q deletion syndrome had eye cancer, a woman's vision improved after stopping a breast cancer drug, a man developed cataracts from using Propecia, and a rare skin disorder called Lipoid Proteinosis was discussed. Also, a tool called OCT is useful for diagnosing macular diseases.

Lymphatic vessels are essential for health and can be targeted to treat various diseases.

Fibroblasts are important in healing diabetic wounds, but high sugar levels can harm their function and slow down the healing process.

Cell polarity signaling controls tissue mechanics and cell fate, with complex interactions and varying pathways across species.

TGF-β signaling is crucial for stem cell maintenance, differentiation, and has implications for cancer treatment.

Diagnosing alopecia areata is challenging and requires careful examination and various tests to distinguish it from other hair loss types.

The symposium concluded that understanding how different species repair tissue and how this changes with age can help advance regenerative medicine.

The document discusses various eye conditions and their treatments, including a rare eye cancer in a baby, vision loss from a cancer drug, cataracts from a baldness treatment, a rare skin disorder, and a specific type of eye disease diagnosed with a special imaging technique.

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.

Understanding how baby skin heals without scars could help develop treatments for adults to heal wounds without leaving scars.

Stem cell therapy, particularly using certain types of cells, shows promise for treating hair loss by stimulating hair growth and development, but more extensive trials are needed to confirm these findings.

Treg dysfunction is linked to various autoimmune skin diseases, and understanding Treg properties is key for new treatments.

Autologous Platelet and Extracellular Vesicle-Rich Plasma (PVRP) has potential in enhancing tissue regeneration and improving hair conditions, but its effectiveness varies due to individual differences.

Triple horizontal scalp biopsies are 98% accurate in diagnosing hair loss, better than single biopsies.

Hair loss can indicate or worsen with systemic diseases, and treating the underlying condition is important.

The document explains hair biology, the causes of hair loss, and reviews various hair loss treatments.

Experts don't fully agree on how to diagnose certain hair growth disorders and more research is needed to understand them better.

Diagnosing diffuse alopecia, a hair loss condition, can be challenging and may require a scalp biopsy or tracking the disease's progression when symptoms and skin tests aren't enough.

Diagnosing hair loss disorders needs clinical, dermoscopic, and histological differences, and checking menstrual cycle, weight changes, drug therapy, and nail changes.

New biopsy techniques and tools improve alopecia diagnosis, and both too much and too little selenium can cause hair loss.

Thyroid disease can cause hair loss and treating thyroid problems might help with hair disorders.

Chemotherapy can cause permanent, non-reversible hair loss similar to pattern baldness.

Hair follicle hyperplasia is common in both benign and malignant skin lymphoproliferative disorders, with a proposed new term "pseudolymphomatous adnexitis."

The document concludes that careful evaluation is key to diagnose and treat women with hair loss, with tests for thyroid, iron, and hormones as needed.

Scalp biopsies are essential for accurately diagnosing alopecia areata.

Different hair evaluation methods have their own pros and cons, and using multiple methods together is best for accurate hair loss diagnosis and tracking.
