Background: Photodynamic therapy (PDT) is a successful treatment for non-melanoma skin cancers in clinical practice. More and more doctors use PDT to cure the patients with skin cancer, especially in the elder. The purpose of this study was to evaluate the efficacy and safety of topical PDT using aminolevulinic acid (5-ALA) in the treatment of Extramammary Paget's disease (EMPD) and its role in surgical improvements.
Methods: A total of 38 cases were included in this study. Lesions were located in the scrotum and the penis. Thirty-one cases had surgical resection of the lesions followed by ALA-PDT (combination of PDT and surgery group). Seven cases received ALA-PDT without receiving surgical resection because the surgery is extremely difficult or the patients refused surgery (simple PDT group). Each tumor lesion was irradiated with 120J/cm(2) using a 635-nm laser for 15min. A total of 3 times of assisted ALA-PDT was applied after surgery.
Results: In the combination group, there was no recurrence in 6 months after treatment. In another group, recurrence occurred in 1 case in 6 months. All patients were able to complete the treatment protocol, with well cosmetic results and no moderate adverse reactions.
Conclusions: As an assistive therapy after tumor resection, ALA-PDT can reduce the excision range of the tumor lesions and will play more important role in the treatment of EMPD.

Background: Complex perianal fistulas, challenging to treat and prone to recurrence, often require surgical intervention that may cause fecal incontinence and lower quality of life due to large surgical wounds and potential sphincter damage. Human umbilical cord-derived MSCs (hUC-MSCs) and their exosomes (hUCMSCs-Exo) may promote wound healing.
Methods: This study assessed the efficacy, mechanisms, and safety of these exosomes in treating complex perianal fistulas in SD rats.

Introduction: Sarcopenia is a disease primarily characterized by age-related loss of skeletal muscle mass, muscle strength, and/or decline in physical performance. Sarcopenia has an insidious onset which can cause functional impairment in the body and increase the risk of falls and disability in the elderly. It significantly increases the likelihood of fractures and mortality, severely impairing the quality of life and health of the elderly people.

In the past decade, the treatment paradigm for chronic lymphocytic leukemia (CLL) has markedly shifted from traditional chemoimmunotherapy towards targeted therapies. A fixed-duration, targeted regimen with venetoclax, a potent oral BCL-2 inhibitor, combined with obinutuzumab, a glycoengineered type II anti-CD20 monoclonal antibody (Ven-Obi), has become the standard to beat for time-limited therapy in CLL. Ven-Obi allows for the rapid induction of remissions with high rates of undetectable minimal residual disease (uMRD) in patients across different treatment settings.

Background: Burr holes can lead to cranial defects that result in cosmetic and functional issues. Effective reconstruction of these burr holes is crucial for improving patient outcomes, yet there is no consensus on the optimal techniques and materials.
Objective: This systematic review critically evaluates the efficacy and safety of various materials used in neurosurgical practice for burr hole reconstruction.

Introduction: Monoamine oxidase-B (MAO-B) inhibitors, as an add-on therapy to levodopa, are widely used in Parkinson's disease (PD). The effects of MAO-B inhibitors on quality of life remain unclear, and the aim of this systematic review and meta-analysis was to assess the efficacy and safety of MAO-B inhibitors on quality of life in different domains.
Methods: We searched PubMed, Embass, and Cochrane Library databases for randomized controlled trials of PD patients who were administered MAO-B inhibitors.
