Fixed Solar Eruption: A Case Report
JEADV Clinical Practice, EarlyView.ABSTRACT Fixed eruption is characterized by recurrent lesions at identical anatomical sites after exposure to a trigger. Although most cases are drug‐induced, ultraviolet (UV) radiation has also been reported as a causative factor. We report a case of fixed solar eruption diagnosed by histopathology and 308 nm excimer light phototesting.

Applied Microbiology and BiotechnologyMelanized fungi are known for their remarkable resilience to environmental stress, largely attributed to the protective properties of melanin. In this study, we establish the black yeast Exophiala viscosa as a non-pathogenic, genetically tractable model ...

Paediatric Melanonychia: Diagnosis and Management
JEADV Clinical Practice, EarlyView.ABSTRACT Longitudinal melanonychia (LM) in children presents unique diagnostic and management challenges that cannot be adequately addressed by applying adult‐based criteria. Unlike in adults, there are no validated clinical, dermoscopic or histopathologic criteria for predicting nail unit melanoma in the paediatric population.

Eczema‐Like Amelanotic Melanoma: A Diagnostic Challenge
JEADV Clinical Practice, EarlyView.ABSTRACT Amelanotic melanoma (AM) is a rare and aggressive variant of cutaneous melanoma characterised by the absence of pigmentation, often leading to delayed diagnosis due to its ability to mimic benign inflammatory or neoplastic conditions. We report the case of a 68‐year‐old woman presenting with a slowly enlarging, erythematous, mildly scaling ...

Land Degradation &Development, EarlyView.ABSTRACT Understanding how climate and vegetation structural complexity jointly shape fungal communities is essential for effective roadside slope restoration. To address this, we examined restoration effects on fungal diversity, community composition, and ecological networks across three climatically distinct regions: dry‐hot valley, subalpine, and ...

Laser &Photonics Reviews, EarlyView.Spatiospectral photoacoustic microscopy is enabled by stable, wavelength‐tunable dual‐pulse excitation from a gain‐switched Ti:sapphire laser. Intrinsically synchronized 532‐nm and NIR‐I pulses provide single‐scan, co‐registered mapping of oxygen saturation and indocyanine green dynamics in vivo.

Lasers in Surgery and Medicine, EarlyView.ABSTRACT Objectives Conventional ablative and photothermal lasers are commonly used to treat superficial pigmentary lesions but often induce thermal injury and post‐inflammatory hyperpigmentation (PIH), particularly in Asian skin. Picosecond 755‐nm alexandrite lasers with diffractive lens arrays (DLA) create laser‐induced optical breakdown (LIOB ...
