This case report describes a challenging diagnosis of Cushing’s syndrome using endocrine tests and imaging, which ultimately identified an adrenal etiology. Successful treatment involved a non-invasive desmopressin stimulation test and right adrenalectomy, leading to improvement in symptoms and health outcomes for the patient.

This review found that 5α‐reductase inhibitors were associated with slightly increased rates of decreased libido, erectile and ejaculatory dysfunction, gynecomastia, and mood disorders compared to placebo, though their long-term effects remain unclear.

Patch testing with different solvents helps find the right minoxidil formulation for those with scalp allergies.

In this study, the authors highlight the potential of intradermal microinjections of dutasteride as an adjunctive therapy for androgenetic alopecia, though they note that information on its effectiveness remains limited.

In this study, engineered mice with a mutation similar to that in Olmsted syndrome showed progressive hair loss due to impaired inner root sheath keratinocyte differentiation and stem cell exhaustion.

QIA-64 software can measure straight wire lengths accurately but needs improvement for curved wires and width measurements.

This study established that a human epidermal model can be utilized to assess 5alpha-reductase activity and evaluate enzyme modulators, such as finasteride, for dermatological applications.

This pilot study found that using skin patting with iontophoresis to deliver dutasteride gel significantly improved hair density, shaft diameter, and pull test scores in men and postmenopausal women with treatment-resistant androgenetic alopecia, with participants reporting high satisfaction and no adverse events.

This abstract provides no results; it is a website notification about cookies and general access to JAMA content.

In this study, the Avalanche brushing protocol demonstrated similar hair reduction effectiveness to the stamping method, but with significantly lower discomfort reported by patients, suggesting it may be preferable for individuals with sensitive skin or dense hair in early treatment sessions.

The researchers reported that glucuronides stored as dried blood spots under ambient conditions exhibited stability equivalent to liquid samples stored at -80°C.

This study found that the majority of "hypoallergenic" hair dyes still triggered allergic reactions in patients sensitive to para-phenylenediamine.

This study developed and validated a sensitive liquid chromatography–mass spectrometry method to measure aristolochic acid‐I in rat plasma, successfully applying it to pharmacokinetic research.

This study developed and validated a simple, accurate, and sensitive HPTLC method for estimating minoxidil and aminexil in topical solutions, demonstrating effective separation and linear measurement of these compounds with %RSD under 2% and high regression coefficients.

In this animal study, topical diazoxide treatment led to increased hair thickness and follicle growth in bald stumptailed macaques without causing notable systemic side effects.

This study investigated spanlastic nanovascular drug delivery systems and found that they can effectively enhance the transport and continuous release of medicines with small particle size, low polydispersity index, and satisfactory entrapment efficiency, showing potential as carriers for drug delivery.

In this study, dutasteride treatment in retinitis pigmentosa mice increased photoreceptor survival and reduced glial activation, suggesting it may offer a neuroprotective effect.

This study found that trichoscopy can diagnose genetic hair shaft abnormalities without plucking or cutting hair, by visualizing characteristic features in a single session.

This study concluded that including intermediate hairs or using relative shaft diameter methods can significantly improve the sensitivity of trichograms in diagnosing female androgenetic alopecia, aligning better with histopathology results.

In this study, researchers conducted additional IHC staining on equine skin sections and found that collagen type III primarily labels the extracellular matrix, while anti-PDGFR-antibody staining highlights cells with long-shaped processes mainly arranged around hair follicles.

In this study, researchers developed a sensitive assay to measure the inhibition of steroid 5-α reductase (5AR) by chemicals like finasteride and dutasteride, revealing species-specific differences in inhibitor efficacy between human and fish cell lines.

This article discusses hair follicle testing as an alternative method for drug abuse screening but reports no new research findings.

This study reports that using stamps to mark scalp incisions with gentian violet ink and a barrier film improved incision symmetry and maintained slot visibility for hair graft insertion in the frontal region.

This study developed expert consensus guidelines on the safe and effective prescription of low-dose oral minoxidil for treating hair loss by engaging 43 dermatologists from 12 countries in a structured Delphi process, yielding 78 consensus items on safety, efficacy, dosing, and monitoring.

This study developed and validated a high-resolution mass spectrometry method to screen for prohibited substances and analyze six endogenous steroids in urine according to World Antidoping Agency requirements, demonstrating its effectiveness for antidoping analysis.

This chapter describes two simple, noninvasive methods — the pull test and modified wash test — which can diagnose and assess the severity of female hair loss, including conditions like telogen effluvium and androgenetic alopecia.

TrichoScan accurately measures hair growth and loss, showing increased hair counts and thickness with treatment.

This study observed that the degradation product PTeCA significantly increased in hair treated with oxidative cosmetics, suggesting it could be a reliable marker for detecting such treatments, with a proposed PTCA cut-off value using PTeCA as the gold standard.

This study reported high analytical performance of an RMP for DHT quantification, with the ability to differentiate between 5α-DHT and 5β-DHT isomers, making it suitable for routine assay standardization and clinical sample evaluation.

This study found that administering botulinum toxin A via Flex-PADs to mouse footpads inhibited sweating similarly to traditional injections, suggesting a promising patient-friendly delivery method for hyperhidrosis treatment.
