This case report describes a 47-year-old male with rare total melanonychia linked to vitamin B12 deficiency, whose nail discoloration and constitutional symptoms improved following vitamin B12 supplementation.

In this case study, researchers observed a 5.8-year-old male with peripheral precocious puberty due to a germ cell tumor, marked by elevated human chorionic gonadotropin levels. Treatment normalized hormone levels and arrested the puberty progression, highlighting melatonin's potential role in transitions to central precocious puberty.

In this case study, a 14-year-old female with premature hair graying showed improved hair color after treatment with a topical Melitane 5% formulation and oral hair supplements.

In this pilot study, researchers found that ex vivo treatment with topical melatonin reduced chemotherapy-induced apoptosis and DNA damage in hair follicle stem cells of human scalp cultures, suggesting melatonin's potential as a protective agent against taxane-induced permanent hair loss.

This study reported the first case of a NIPAL4 c.527C>A mutation in Romanian patients with autosomal recessive congenital ichthyosis, finding that NIPAL4 mutations are more common than TGM1 mutations in this population.

This study found that an aqueous extract of Bacopa procumbens improved motor function and preserved neuronal structure in a mouse model of Parkinson's disease, suggesting its neuroprotective potential.

In this study, alternating PRP with microneedling produced faster hair growth results in patients with mild to moderate androgenetic alopecia compared to PRP alone.

In this study, variations in candle nut oil concentration (5%, 6%, 7%) impacted the characteristics and stability of a hair tonic nanoemulsion, influencing factors like droplet size, pH, and viscosity.

This study found that decision-making effects related to time of day and chronotype were only significant when using RNA-based chronotype measurements, indicating molecular clock differences may influence these behaviors.

This study investigated the use of methylene blue in a niosomal hydrogel for photodynamic treatment of acne and found that it led to significant improvement in inflammation compared to IPL treatment.

In this case report, researchers described a 6-year-old girl with severe mandibuloacral dysplasia type A, noting unique physical deformities and a rare homozygous LMNA gene mutation not commonly associated with the condition.

This study used melamine formaldehyde particles to measure a pH gradient along the hair shaft, showing a significant pH decrease from the hair sheath to the external shaft.

This review discusses the proposed shift from PCOS to PMOS, emphasizing a comprehensive approach to diagnosis and management, but reports no new clinical results.

This study found that permanent makeup pigments were applied at similar depths as traditional tattoo inks in mice but faded over time due to larger inorganic pigments.

In this study, combining 2% minoxidil with weekly microneedling significantly improved hair regrowth in women with female pattern hair loss compared to using minoxidil alone, with an 85% effective rate reported in the group receiving both treatments over a 24-week period.

This source explores melatonin's roles beyond circadian rhythm regulation, reporting its benefits in skin conditions like dermatitis, melasma, alopecia, psoriasis, and skin aging due to its antioxidant, anti-inflammatory, and immunomodulatory properties, while highlighting the need for more trials on optimal dosing and long-term safety.

This study found that the circadian clock in mouse skin regulates cell proliferation and affects sensitivity to UVB-induced DNA damage, with potential implications for understanding human skin cancer risk.

This study identified three symptom trajectory groups in individuals with PMDD, highlighting variations in symptom severity and duration across the luteal and follicular phases.

This study on androgenetic alopecia in mice introduced a novel therapy combining microneedle patches and cold atmospheric plasma to enhance minoxidil delivery, leading to improved hair regeneration by boosting vascular growth and reshaping the hair follicle microenvironment.

This study found that treating cashmere goat kids with melatonin significantly increased secondary hair follicle density, improving cashmere quality and yield, likely through mechanisms involving the MAPK signaling pathway.

In this study, PRP was found to show promise in treating melasma, offering consistent positive outcomes and satisfaction rates among patients, especially when combined with treatments like hydroquinone and tranexamic acid, though further research is needed to confirm long-term efficacy and safety.

This article describes two cases of plica neuropathica, a rare hair condition involving severe matting, and discusses possible contributing factors and diagnosis methods while reporting no new scientific results.

This study found that non-ablative fractional laser treatments in Korean patients had a low complication rate, with adverse events being temporary and not resulting in long-term consequences.

This article provides guidelines by ASPEN for managing parenteral nutrition shortages but reports no new clinical findings.

This study found that melatonin treatment in Cashmere goat kids enhances the density of secondary hair follicles and improves Cashmere quality by regulating the MAPK pathway and reducing cell apoptosis.

This study developed a personalized microneedle that delivers finasteride directly to the skin, facilitating a sustained release and potentially reducing side effects associated with oral administration.

In this self-controlled comparative study of 16 women with Female Pattern Hair Loss, MMP® with Minoxidil showed a better response in the parietal-vertex regions in less advanced cases compared to standard Minoxidil treatment, though overall effectiveness was similar.

In this study, Spectral DNC-N® significantly reduced hair shedding and increased hair mass and density in women with early female pattern hair loss, with effects evident after 3 months and sustained through 6 months.

This review discusses the clinical phenotypes of primary mitochondrial cytopathies linked to significant genetic defects in mitochondrial DNA, reporting no new clinical results; the authors emphasize the need for differential diagnosis.

This study reports pseudopili annulati in a dark-haired Chinese girl, identifying the unique appearance and structural characteristics of her hair without finding abnormalities in the cuticle and cortex.
