Background:. Currently, the evaluation of pigmented skin lesions relies on dermoscopy, which has become the standard of care. As melanoma is one of the principal areas of expertise in plastic surgery, it is essential that diagnostic skills be acquired during the course of specialization. This study aimed to assess the impact and effectiveness of a brief and intensive dermoscopy training program for plastic surgery residents. Methods:. This study was carried out on a group of 41 doctors, who were divided into three categories based on their experience in dermoscopy (none, intermediate, and advanced). A preliminary assessment of each participant’s baseline knowledge was conducted by using a 15-query test. Subsequently, the participants attended a 90-minute lecture on diagnostic techniques and the process of differentiating between various skin lesions. To determine the effectiveness of the lecture in improving diagnostic skills, the participants were tested immediately after the lecture and again after a 3-month period. Results:. At the conclusion of the final examination, all three groups achieved an accuracy rate of at least 80% for dermatoscopic diagnosis. However, none of the groups was completely successful. The variations in diagnostic accuracy among the three groups are presented, and P values were calculated for each group. Conclusion:. The short, intensive course of dermoscopy has proven to have a significant positive impact on plastic surgeons in their postdegree training program.

Obesity is defined as a complex, systemic disease characterized by excessive and dysfunctional adipose tissue, leading to adverse health effects. This condition is marked by low-grade inflammation, oxidative stress, and metabolic abnormalities, including mitochondrial dysfunction. These factors promote energy dysregulation and impact body composition not only by increasing body fat but also by promoting skeletal muscle mass atrophy. The decline in muscle mass is associated with an increased risk of all-cause mortality in individuals with this disease. The European Food Safety Authority approved pyrroloquinoline quinone (PQQ), a natural compound, as a dietary supplement in 2018. This narrative review aims to provide a comprehensive overview of the potential role of PQQ, based on its anti-inflammatory and antioxidant properties, in addressing dysfunctional adipose tissue metabolism and related disorders.
