Purpose: The study was conducted to investigate the skin hydration level in various body sites and identify the influencing factors in neonates.
Methods: An exploratory comparison study was designed to measure the stratum corneum hydration, using a National DM-R2 on the forehead, abdomen, buttocks, and the back of the hands and feet of 198 neonates including 92 premature infants.
Results: The results showed 32.7%-36.5% of stratum corneum hydration for all sites. Premature infants revealed a higher hydration level on the peripheral sites (dorsal hand and feet) than those of the full-term infants, possibly resulting from therapeutic regimens including an incubator or radiant warmer. Infants in an incubator showed a higher hydration level than those in radiant warmers, suggesting more attention to fluid management for infants in the open environment. In addition, all stratum corneum hydration measurements except one, from the forehead, showed a positive correlation with postnatal age in full-term infants while showing no relation to any measurements in premature infants.
Conclusion: The study demonstrated the very low skin hydration levels in hospitalized neonates, particularly in premature neonates with more susceptible skin hydration instability despite therapeutic interventions for fluid balance. More vigilant fluid management is imperative in neonates, particularly those in the open environment.

Background: Identification of predictive biomarkers is crucial for formulating preventive interventions and halting the progression of atopic march. Although controversial, the use of accessible markers to predict or detect early onset of atopic diseases is highly desirable. Therefore, this study aimed to investigate whether corneal squamous cell carcinoma antigen-1 (SCCA1) collected from infants can predict the development of atopic dermatitis and food allergy.

Methods that facilitate molecular identification and imaging are required to evaluate drug penetration into tissues. Time-of-flight secondary ion mass spectrometry (ToF-SIMS), which has high spatial resolution and allows 3D distribution imaging of organic materials, is suitable for this purpose. However, the complexity of ToF-SIMS data, which includes nonlinear factors, makes interpretation challenging.

Atopic dermatitis (AD) is a chronic inflammatory skin condition. Natural products have gained traction in AD treatment due to their accessibility, low toxicity, and favorable pharmacological properties. However, their application is primarily constrained by poor solubility, instability, and limited permeability.

Purpose: Atopic dermatitis (AD) is the most common chronic inflammatory skin disease that severely impairs patient's life quality and represents significant therapeutic challenge due to its pathophysiology arising from skin barrier dysfunction. Topical corticosteroids, the mainstay treatment for mild to moderate AD, are usually formulated into conventional dosage forms that are impeded by low drug permeation, resulting in high doses with consequent adverse effects, and also lack properties that would strengthen the skin barrier. Herein, we aimed to develop biomimetic lamellar lyotropic liquid crystals (LLCs), offering a novel alternative to conventional AD treatment.

Article Synopsis
- Transdermal drug delivery using SPACE-modified liposomal chrysomycin A (CA@SPACE-LP) shows promise for treating skin diseases like melanoma and MRSA infections.
- In vitro studies reveal that CA@SPACE-LP significantly enhances drug penetration into skin layers, achieving a threefold increase in intradermal drug concentration compared to free chrysomycin A.
- In vivo results indicate that CA@SPACE-LP effectively suppresses melanoma tumor growth by about 60% and outperforms conventional treatments for MRSA, suggesting its potential for combined cancer and infection therapy.
