Summary
This review updates evidence on narrowband UVB phototherapy (NB-UVB), confirming its role as a first-line treatment for various skin conditions like psoriasis and vitiligo due to its effectiveness and safety.
Area of Science:
- Dermatology
- Photomedicine
Background:
- Narrowband UVB phototherapy (NB-UVB) is a widely used dermatological treatment.
- Evidence and clinical practices require regular updates.
Purpose of the Study:
- To provide an updated review of scientific evidence and clinical practice for NB-UVB in dermatology.
- To offer recommendations for integrating NB-UVB with modern systemic and biologic therapies.
Main Methods:
- Literature review and synthesis of current scientific evidence.
- Analysis of clinical practice guidelines and emerging research.
Main Results:
- NB-UVB is confirmed as a first-line therapy for psoriasis, vitiligo, atopic dermatitis, early mycosis fungoides, and photodermatoses.
- Efficacy, safety, and cost-effectiveness of NB-UVB are highlighted.
- NB-UVB shows promise for integration with next-generation systemic therapies.
Conclusions:
- NB-UVB remains a cornerstone therapy in dermatology.
- Updated recommendations facilitate efficient, patient-centered care in the era of targeted therapies.

01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:35Mutations
Mutations are changes in the sequence of DNA. These changes can occur spontaneously or they can be induced by exposure to environmental factors. Mutations can be characterized in a number of different ways: whether and how they alter the amino acid sequence of the protein, whether they occur over a small or large area of DNA, and whether they occur in somatic cells or germline cells.

01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:02Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for electronic transitions. As a result...
