Evolution and duration of nodules in severe nodular acne on the back: results from a four-week non-interventional, prospective study

Photodynamic therapy for severe acne

Acne is an inflammatory cutaneous disease affecting the pilosebaceous unit and hair follicles on the face, neck, back, and chest, with a typical onset in adolescence and, in some cases, persisting into adulthood. Systemic treatments with antibiotics or isotretinoin present many limitations, like antimicrobial resistance phenomena and teratogenicity, which appear more relevant in the pediatric population, both for the treatment-related risks and for the reticence of the parents. Photodynamic therapy (PDT) has already shown encouraging results in the treatment of acne in adult patients, with good aesthetic results compared to other therapies and few side effects. However, its use is still not standardized in the pediatric population. On this topic, we report our experience with PDT in a young patient affected by dorsal acne. After five sessions of ALA-PDT at monthly intervals, a remarkable improvement of the lesions was observed, with the healing of the inflamed nodules and pustules, resolution of the painful symptoms, and an acceptable cosmetic outcome. Our case is paradigmatic of the potentiality of PDT to treat difficult and resistant-to-treatment lesions. Despite being time-consuming, this procedure has been demonstrated to be safe and well-tolerated. Lastly, the therapy is also well accepted by parents, due to its minimal invasiveness and mild side effects, compared to the other therapeutic options.

Exploring the Multifaceted Impact of Acne on Quality of Life and Well-Being

A suitable portion of the total population still suffers through acne vulgaris, a widespread dermatological illness that mostly affects teens and young adults. Although acne is typically considered to be a cosmetic problem, recent research has concluded that certainly it has a significant role on impacting many physiological aspects of human health. This thorough investigation attempts to examine the intricate effects of acne on human physiology, taking into consideration both systemic and local effects. The study synthesizes research from a number of scientific disciplines, including dermatology, endocrinology, immunology, and psychoneuroimmunology. It investigates the complex interrelationships between several factors, such as sebum production, follicular hyperkeratinization, hormone imbalance, and Propionibacterium acnes colonisation, that lead to the development of acne. The study also sheds information on the intricate physiological mechanisms, oxidative stress, and immune response that contribute to the aetiology of acne. Along with it, the review investigates the relationship between endocrine problems and acne, emphasizing hormonal anomalies and their possible role in acne severity. The psychological effects of acne are also discussed, including the psychological problems, concerns with self-esteem, and decreased quality of life that acne sufferers encounter. On comprehensively examining the diverse physiological aspects affected by acne, this review provides a foundation for future research endeavours and informs the development of targeted therapeutic interventions. Ultimately, the integration of multidisciplinary approaches will enable healthcare professionals to address the physiological complexities of acne and improve the overall well-being of individuals affected by this common skin condition.
