Any drug can cause skin reactions, but antibiotics, NSAIDs, and psychotropic drugs are more common, with some reactions being life-threatening.

Certain micronutrients may improve hair and nail health, but more research is needed to confirm their benefits.

Testosterone therapy aims to treat hormone deficiencies and various conditions safely and effectively, but requires careful patient monitoring due to potential side effects.

This study found that the prevalence of polycystic ovary syndrome was 16.6% with Rotterdam criteria but decreased to 6.3% or 8.5% when using alternative criteria involving antral follicle count or anti-Müllerian hormone.

This study found that the E2-ANGPT2 pathway is involved in hair follicle regulation and that ANGPT2 treatment increased hair density in modeled female pattern hair loss, suggesting potential therapeutic use.

This review discusses the role of estrogens in hair follicle cycling and the skin, highlighting the need for more research on estrogen signaling pathways and their interactions with other factors in hair biology.

This study found that measuring specific steroid hormone levels can aid in diagnosing P450 oxidoreductase deficiency, a subtype of congenital adrenal hyperplasia, by distinguishing affected patients from healthy individuals.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This systematic review found that Janus kinase inhibitors have shown beneficial effects for psoriasis and alopecia areata, with promising preliminary results in other skin conditions, though more research is needed to define dosing and safety profiles.

This review discusses the relationship between psoriasis and autoimmunity, focusing on autoimmune co-morbidities, but reports no new research findings.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study found that while isotretinoin lowered levels of female hormones in patients with severe acne, it did not significantly impact ovarian reserve function.

This study identified key genes linked to immune cells and potential therapeutic compounds for alopecia areata by evaluating upregulated genes from patient datasets, highlighting T and NK cell involvement in hair follicle attack and suggesting drug candidates through molecular docking and dynamics simulations.

In this review, researchers explored the multifaceted role of NF-κB signaling in various biological processes and diseases, including its interactions with other pathways, and discussed possible therapeutic approaches targeting this pathway for treating conditions like cancer, autoimmune disorders, and COVID-19.

This study found that sex hormone-binding globulin promotes facial aging, while sex steroid hormones such as testosterone and estradiol inhibit it, with growth hormone levels showing no significant effect.

In this study, a medicated hair growth tonic containing RJ extract increased hair counts, the proportion of anagen phase hairs, and scalp moisture in human trials, although the specific role of RJ in hair growth remains unclear due to other active ingredients.

This study developed a liquid chromatography with tandem mass spectrometry method to detect sex hormones in health supplements from Hanoi, Vietnam, finding three out of 16 samples contained sex hormones, including banned testosterone at low levels (~0.5 mg/kg).

This study observed that Greek Caucasian women with PCOS had distinct serum hormone levels and a specific AKT2 gene SNP, which may play a role in the condition's characteristics.

This study found that topical application of TSG from Polygonum multiflorum promoted hair regrowth in depilated mice, potentially through the inhibition of apoptosis-related proteins.

This study found that sex differences in somatostatin biosynthesis in rat hypothalamic neurons develop between postnatal day 1 and 5, influenced by the conversion of testosterone to estrogen.

The drinkable supplement increased hair growth and was safe for women with hair loss.

This study suggests men with early androgenetic alopecia might have hormonal profiles similar to women with polycystic ovarian syndrome, potentially indicating risk for related health complications.

This review discusses the role of immune cells in the pathogenesis of alopecia areata and highlights emerging immunomodulatory strategies and novel therapeutic targets aimed at offering more effective and durable treatments for this autoimmune hair loss disorder.

This review aims to help medical practitioners understand inferential statistical methods to critically evaluate clinical trial design and analyses, but it doesn’t present new research findings.

This study observed that in vitro exposure to dihydrotestosterone worsened COVID-19 spike protein-induced endothelial injury, while spironolactone showed potential in reducing this effect, suggesting a rationale for further evaluation in treating COVID-19.

This study found that EP 2 signaling is crucial for macrophage recruitment and inflammatory regulation in the injured heart, impacting cardiac repair processes.

In this study, conducted at a tertiary care hospital in Chennai, adverse events during blood donation were observed in 0.42% of donors, predominantly affecting first-time male donors, and were mostly vasovagal reactions such as giddiness and sweating.

This review discusses the features of regulatory T cells and the modulation of Foxp3, emphasizing post-translational modifications' impact on Treg function but reports no new clinical results.

This study found that dendritic epidermal T cells and their exosomes enhance epidermal stem cell proliferation, accelerating wound re-epithelialization in the skin.

PSA testing is a reliable method for detecting prostate cancer, and opioids may lower PSA levels, but triglycerides don't affect prostate cancer risk.
