The document reviews key historical figures and discoveries in dermatology.

This review discusses the uses and toxicological data of eleven unsaturated halogenated hydrocarbons, including dichloroacetylene, allyl chloride, hexachlorobutadiene, β-chloroprene, vinyl chloride, trichloroethylene, and perchloroethylene, but presents no new findings.

This article reviews the properties, uses, and toxic effects of eleven unsaturated halogenated hydrocarbons, highlighting the risks associated with compounds like dichloroacetylene, allyl chloride, and vinyl chloride, and reports no new experimental findings.

This report examines the mechanisms by which TCDD affects human epidermal and carcinoma cells, aiming to create a risk assessment model for halogenated aromatic compounds, but presents no new clinical results.

Most women with excessive hair growth have PCOS; treatment varies and focuses on preventing new hair, with electrolysis as the only permanent removal method.

This review discusses the potential impact of endocrine-disrupting chemicals and body size on pubertal onset and progression, highlighting critical gaps and priorities for future research without presenting new clinical results.

Some drugs can cause hair loss or increase hair growth, but these effects are usually reversible when the drug is stopped.

This article reviews drug-induced hair changes, highlighting that while many drugs are occasionally linked to hair loss, this connection has been conclusively established for only a few, and such hair loss is typically reversible.

This review discusses niosomes' increasing popularity in dermatology for topical drug delivery due to their ability to enhance drug penetration, provide sustained release, and carry various drugs, while reporting no new clinical findings.

This paper reviews causes of hirsutism in women and emphasizes the importance of identifying underlying conditions for risk assessment, though it reports no new clinical findings.

This review discusses various substances that can impact male fertility and stresses that products should be confirmed 'sperm-safe' through rigorous testing, not assumptions; it reports no new study results.

This article reviews how various drugs may cause hair loss, stimulate growth, or alter hair characteristics, but reports no new clinical results; drug-induced hair loss is typically reversible.

Hair can indicate early signs of metabolic disorders, with issues like protein deficiency stopping hair growth.

This review discusses various causes of hair loss, emphasizing the importance of a structured diagnostic approach, and reports no new clinical findings.

This study found that microplastics on the Lebanese Mediterranean coast transport various organic and inorganic pollutants, posing threats to marine organisms and potentially human health.

This study developed a new analytical method to identify a wide range of endocrine disrupting compounds in full-term amniotic fluid, revealing diverse substances with potential endocrine activity.

Some drugs can cause hair loss or growth, but hair usually returns to normal after stopping the drug.

Psoriasis treatments range from topical creams to systemic medications with serious side effects, and while treatments can manage symptoms, there is no cure.

This letter to the editor shares concerns about possible systemic effects from topical dinitrochlorobenzene therapy in a 25-year-old man treating alopecia areata.

Among Australian fur seals at one colony, this study found that alopecia, primarily affecting juvenile females, is linked to hair shaft fractures associated with low tyrosine and zinc levels, as well as higher pollutant exposure.

This review discusses the historical concepts of hirsutism in Unani Medicine and evaluates herbal treatments, indicating these may influence underlying endocrine issues but current evidence remains insufficient.

In this study, researchers found that TCDD exposure accelerated differentiation and altered gene expression in human epidermal cells, indicating the epidermal barrier as a target of TCDD-activated AHR.

This study found that high doses of TCB caused severe toxicity in cotton top marmoset monkeys, with clinical and histological changes similar to those in humans and other primates exposed to PCBs.

This study developed a chalcone-based molecule that significantly increased tyrosinase inhibition and solubility, showing potential as a safe and effective skin depigmenting and antiaging agent, with supportive epigenetic and antioxidant properties observed in vitro.

This study found that enzyme activity critical to cancer induction by polycyclic aromatic hydrocarbons in human hair follicles increased after using a crude coal tar-containing shampoo for four days and was substantially inhibited by imidazole compounds.

This study investigated the modes of action of selected pesticides, suggesting that prochloraz and tebuconazole are linked to reproductive disorders via steroidogenesis disruption, while mancozeb involves inflammatory processes.

In this study, researchers observed that TCDD exposure in mice enhanced sebaceous gland differentiation and lipid production before causing seboatrophy, providing insights into the cellular events that may contribute to chloracne pathogenesis.

This study developed and validated a method using hair samples to simultaneously detect bisphenols and parabens, enabling the quantification of these endocrine disruptors in a hospital population’s hair.

This study found that several preservatives, including triclocarban and triclosan, showed potential endocrine-disrupting effects on various nuclear receptors in both in silico and in vitro models.

This report suggests that TCDD may alter human epidermal stem cell populations by upregulating c-Myc, potentially leading to increased stem cell turnover during chloracne development.
