Summary: This study compared the efficacy and safety of KTP 532-nm picosecond laser and alexandrite 755-nm picosecond laser for the treatment of solar lentigines in Asians. Results showed that alexandrite 755-nm picosecond laser had better treatment outcome and higher patient satisfaction.

Summary: Favre-Racouchot disease is an occupational disorder characterized by solar elastosis, open and cystically dilated comedones, primarily affecting elderly light-complexioned men around the eyes and temples. It is benign and caused by chronic excessive ultraviolet exposure, ionizing radiation, and/or smoking. Although malignant skin neoplasms are rare in FRD, there may be a protective element within FRD against carcinogenesis.

Summary: This study investigated the efficacy and safety of using a microneedling radiofrequency device with polynucleotides versus radiofrequency alone for the treatment of melasma. The results showed that both treatments significantly improved the symptoms of melasma, with no significant differences between the two. Microneedling radiofrequency treatment was found to be safe and effective in improving skin roughness and can be used as an adjunctive treatment option for melasma.

Summary: The study indicates that alexandrite 755nm picosecond and Nd:YAG 1064nm picosecond lasers are effective and safe for treating UVB-induced hyperpigmentation. The treatment outcomes of the 755nm picosecond laser appeared to be superior to the 1064nm picosecond laser, especially for FPT4 skin type.

Summary: This study analyzed the formation mechanism of solar lentigo (SL) in the skin. It was found that the decrease of type IV collagen in the basement membrane and the uptake of melanin pigment by dermal cells are related to the formation of SL.

Summary: Clinical medicine is facing the challenge of repairing soft-tissue defects. Decellularized extracellular matrix (d-ECM), which has extensive sources and excellent biological and mechanical properties, has been developed as a natural scaffold. However, different decellularization techniques affect the residual components of d-ECM and have varying effects on inflammation and tissue regeneration. This article summarizes the current studies on the preparation of d-ECM, residual substances, inflammation, and immune cells affecting the fate of d-ECM.

Summary: This study evaluated the effect and safety of EGF-containing ointment for treating solar lentigines with a QS 532nm Nd:YAG laser. The results showed that the use of EGF ointment could efficiently reduce the occurrence of PIH, and significantly improve patient satisfaction and pigment clearance.

Summary: This study compared the differential expressions of collagen type I (COL I) and collagen type VI (COL VI) in skins with biological aging and photoaging. The results showed that solar radiation can more rapidly degrade and replace the collagen fibers of the skin, regardless of age. Additionally, the expression of COL I and COL VI differs between healthy skin tissue and photoaging skin tissue.

Summary: Ultraviolet radiation exposure is the primary environmental determinant of skin cancer and photoaging. The study showed that solar elastosis alters the structure of collagen in the skin, and the expression of COL I varies between healthy, aging, and pathological skin tissues. Additionally, the severity of solar elastosis did not appear to be completely influenced by age, and UV radiation leads to a more rapid degradation of collagen fibers in the skin, especially in cases of photoaging and skin cancers.

Summary: This study reports a case of Rumpel-Leede phenomenon in a 49-year-old woman who underwent en bloc spondylectomy for a giant cell tumor of the spine. The condition appeared after the application of pneumatic compression for venous thromboembolism prophylaxis, and the lesions resolved after discontinuation of compression. Most reported cases are seen in patients with a history of diabetes mellitus, hypertension, or thrombocytopenia, but this case occurred in a patient without underlying medical conditions. Capillary fragility combined with increased intracapillary pressure was hypothesized as the underlying mechanism.

Summary: This study investigated the effects of gender-affirming hormone therapy and procedures on the skin in transgender individuals. The results showed that testosterone treatment resulted in acne and male pattern hair loss, while hormone therapy in transgender women caused melasma and female pattern hair loss.
