This review discusses OCD spectrum disorders with dermatological symptoms, emphasizing their clinical features, neurobiology, and treatment options, while noting the need for more controlled studies.

This study found that brindled mottled mice, a model of Kinky hair syndrome, exhibited abnormal development of catecholamine neurons, with increased TH-immunoreactive neurons and altered neurochemical profiles compared to controls.

This case report describes a 23-year-old Asian woman with fluoxetine non-responsive trichotillomania who showed significant improvement with bupropion and cognitive behavior therapy, though confirmation in larger trials is needed.

This study demonstrated that allopregnanolone administration caused significant scratching in atopic dermatitis mice, and ethanol-induced scratching may be linked to increased brain allopregnanolone levels.

This case report describes a 66-year-old male with benign prostatic hyperplasia who developed urinary incontinence after starting venlafaxine, which resolved upon discontinuation of the medication.

In this study, researchers demonstrated that human hair follicle outer root sheath cells release ATP, serotonin, and histamine in response to mechanical stimulation, which subsequently activates surrounding sensory neurons.

This study found that SM-215 applied to mice increased hair follicle activity and capillary presence, promoting hair growth compared to non-treatment.

This study concluded that 16β-methyl-17α-benzoyloxypregnen-4-en-3,20-dione may be a promising treatment for androgen-dependent diseases and epilepsy due to its antioxidant effects and impact on GABAergic and serotonergic metabolism in rats.

This review discusses the potential link between early postnatal allopregnanolone levels and vulnerability to drug abuse in adulthood, noting a need for more in-depth studies to confirm this relationship.

This case report describes reversible hair loss in a patient taking aripiprazole, suggesting this side effect may be common among psychotropic medications.

This study developed a sensitive method for analyzing nine biomarkers in hair, revealing an association between chronic tobacco smoke exposure and stress, highlighting its potential use in understanding the relationship between long-term tobacco exposure and chronic stress.

This study identified that the MC-5-HT-HTR2A axis plays a role in chronic pruritus in a mouse model of SADBE-induced allergic contact dermatitis, suggesting potential for therapeutic targeting.

In this review, researchers examined nine studies on botulinum toxin type A's effects on biomarkers in chronic head and neck conditions, finding significant, though low to moderate certainty, changes in markers like CGRP and serotonin associated with inflammation and mood disorders.

This case report describes a rare instance of gynecomastia in a male patient undergoing mirtazapine treatment for depression, suggesting the drug as a probable cause after ruling out other factors.

In this study, researchers synthesized the fictional compound 1-hydroxyindole and discovered its potential medical applications, including anti-aging properties, itch relief for atopic dermatitis, and as a stronger treatment for dementia compared to cilostazol. Additionally, they found that 1-methoxyindole derivatives function as anticancer agents in diets.

This review explores the hormonal factors linking polycystic ovary syndrome and psychiatric disorders, such as eating disorders, emphasizing a bidirectional relationship that necessitates a multidisciplinary treatment approach; it reports no new clinical results.

Skin and hair cells release serotonin and histamine naturally, which could help improve skin health.

This review supports iron deficiency anemia as a valid cause of chronic generalized pruritus and suggests potential mechanisms by which iron deficiency may lead to pruritus, but reports no new clinical results.

This review highlights scientific information about the medicinal uses and phytochemistry of Musa paradisiaca plant parts, which are traditionally used in human medicine to treat conditions such as diabetes, diarrhoea, hypertension, and ulcers, and exhibit various pharmacological activities including antidiabetic, antioxidant, and wound healing effects.

This study found that neonatal administration of Allopregnanolone may mitigate some behavioral effects of early maternal separation in adolescence, but also lead to similar adverse effects as the separation in adulthood.

This article highlights that isotretinoin can rarely cause persistent sexual dysfunction, similar to finasteride and certain antidepressants, a side effect not mentioned in the drug’s data sheet.

This review discusses treatment options for trichotillomania, focusing on cognitive-behavioral interventions and promising developments in combined pharmacotherapy and therapy approaches, but reports no new findings.
