Background: Calcium hydroxylapatite (CaHA) dermal filler is used for a variety of aesthetic treatments; however, the safety and effectiveness of diluted CaHA for the treatment of décolleté wrinkles have not been established., Objective: To demonstrate the effectiveness and safety of diluted CaHA (Radiesse; 1:2 CaHA:saline) injection for the improvement of décolleté wrinkles in females., Methods: Eligible females with moderate or severe ratings on the Merz Aesthetic Scale (MAS) Decollete Wrinkles - At Rest received up to 3 injection cycles of diluted CaHA either 8 weeks apart (3 injection cycles) or 16 weeks apart (2 injection cycles). Effectiveness was evaluated by improvement on the MAS. Adverse events were recorded over a 52 week period., Results: Sixteen weeks after the last treatment, the response rate (1-point improvement or greater) on the MAS Decollete Wrinkles - At Rest was 73.5% (P<0.0001; pooled sample) for all patients. The use of diluted CaHA in the decollete also demonstrated a favorable safety profile., Conclusions: Diluted CaHA is a safe and effective treatment for the improvement of decollete wrinkles in females.J Drugs Dermatol. 2024;23(7):551-556.  doi:10.36849/JDD.8261.

This article's main contributions are twofold: 1) to demonstrate how to apply the general European Union's High-Level Expert Group's (EU HLEG) guidelines for trustworthy AI in practice for the domain of healthcare and 2) to investigate the research question of what does "trustworthy AI" mean at the time of the COVID-19 pandemic. To this end, we present the results of a post-hoc self-assessment to evaluate the trustworthiness of an AI system for predicting a multiregional score conveying the degree of lung compromise in COVID-19 patients, developed and verified by an interdisciplinary team with members from academia, public hospitals, and industry in time of pandemic. The AI system aims to help radiologists to estimate and communicate the severity of damage in a patient's lung from Chest X-rays. It has been experimentally deployed in the radiology department of the ASST Spedali Civili clinic in Brescia, Italy, since December 2020 during pandemic time. The methodology we have applied for our post-hoc assessment, called Z-Inspection®, uses sociotechnical scenarios to identify ethical, technical, and domain-specific issues in the use of the AI system in the context of the pandemic.

To investigate the efficacy and safety of the addition of the microdroplet technique to conventional injections for the treatment of crow's feet with incobotulinumtoxin A, four women with moderate-to-severe crow's feet at maximum expression received three standard intradermal injections of incobotulinumtoxin A on both sides of the face (4U [0.1mL] at each injection point) plus six microdroplet injections of incobotulinumtoxin A (0.5U [0.025mL] per point) into the lateral canthal area on the left side of the face and an equal quantity of saline at the same injection points on the right side of the face. Investigators and subjects independently evaluated the degree of rhytide improvement both at rest and maximum expression after 28 and 84 days. Investigator and subject ratings for wrinkle severity at maximum expression were improved to a greater degree on the side of the face treated with additional microdroplet incobotulinumtoxin A in all subjects, except one who was over 65 years old. All women preferred the results on the left side of their face. Treatment was well tolerated. The addition of the microdroplet technique to standard practice for injecting incobotulinumtoxin A is a promising procedure for the treatment of crow's feet in women with moderate-to-severe wrinkles.

On the basis of follow-up examinations in 96 patients with diversion of urine, the effects of urinary stasis on serum electrolytes and the acid-alkali balance are demonstrated and discussed. Early correction of urinary stasis is necessary in order to avoid any impairment of the distal functioning of the tubules and the collecting tubes. The special position of serum chloride in any diversion of urine is demonstrated.

The results of 48 transperitoneal, bilateral lymphadenectomies are analysed. In stage I and II we achieved a 2-year survival time of 85.2%. The operative approach is described. The findings in patients without response to the therapy are emphasized and discussed.
