Obesity and increased waist circumference are associated with all the factors constituting the metabolic syndrome (type 2 diabetes, sleep apnea, hypertension, dyslipidaemia, acute myocardial infarction…) and also with an increased mortality. One of the main methods to determine the obesity is through the body mass index (BMI), which is calculated as weight in kilograms, divided by height in metres squared. Obesity is considered to be when the BMI is greater than 30 kg/m2. The association with psoriasis has been revealed in different epidemiological studies and clinical trials and mainly affects patients who develop more severe forms of psoriasis. We report an obese patient under treatment with Risankizumab with successful and sustained response over 52 weeks, as a very promising therapeutic approach as an efficient treatment in this patients

Androgenetic alopecia (AGA) is an androgen-dependent process and represents the most frequent non-scarring alopecia. Treatments for AGA do not always achieve a satisfactory result for the patient, and sometimes cause side effects that lead to discontinuation of treatment. AGA therapeutics currently includes topical and oral drugs, as well as follicular unit micro-transplantation techniques. Tissue engineering (TE) is postulated as one of the possible future solutions to the problem and aims to develop fully functional hair follicles that maintain their cyclic rhythm in a physiological manner. However, despite its great potential, reconstitution of fully functional hair follicles is still a challenge to overcome and the knowledge gained of the key processes in hair follicle morphogenesis and biology has not yet been translated into effective replacement therapies in clinical practice. To achieve this, it is necessary to research and develop new approaches, techniques and biomaterials. In this review, present and emerging hair follicle bioengineering strategies are evaluated. The current problems of these bioengineering techniques are discussed, as well as the advantages and disadvantages, and the future prospects for the field of TE and successful hair follicle regeneration.

Photodynamic therapy (PDT) is an effective treatment option for the treatment of superficial basal cell carcinoma (sBCC). Recent publications have demonstrated that PDT with 7.8% 5‐aminolaevulinic acid nanoemulsion‐based gel (BF‐200 ALA‐PDT) is an effective and safe alternative for the treatment of sBCC). To investigate the efficacy and safety of 7.8% 5‐aminolaevulinic acid nanoemulsion‐based gel (BF‐200 ALA)‐PDT for the treatment of sBCC. A non‐controlled, open‐label single centre study was conducted. Patients received one PDT cycle with two PDT sessions one‐week apart. In case that clinical‐dermoscopy evaluation of treatment outcome revealed remaining lesions, a second PDT cycle was performed. The clinical results at the dermoscopy and fluorescence diagnosis level were histologically confirmed in all patients. Treatment response was evaluated 3, 6, and 12 months after last PDT session. A total of 31 patients (12 men and 19 women), with a median age of 63.74 years were included in this study. 3‐month after PDT‐session, 23/31 patients were complete responders (74.19%) after two BF‐200 ALA ‐PDT sessions. Esthetic outcome was considered good‐to‐excellent. 5 Aminolevulinic acid 7.8% nanoemulsion‐based gel (BF‐200 ALA) PDT is an effective therapy option for the treatment of sBCC. Complete clearance rates were higher in those patients who received only one PDT cycle. These results show a similar tendency as shown in other publications.
