Aim: We assessed the effects of autologous punch grafts skin transplantation in combination with negative pressure dressings and A pliable polyester mesh impregnated with hydrocolloid particles petroleum jelly particles, NOSF particles (Nano-Oligo Saccharide Factor) wound dressing in patients with various underlying conditions in our specialized wound clinic. Method: Patients with ulceration in the granulation phase of wound healing were selected for treatment with a punch graft procedure. The skin of the inner side of the upper arm was infiltrated with lidocaine for local anesthesia; afterwards, the fullthickness skin grafts were taken with a disposable biopsy punch and directly placed on a gauze with normal saline. The grafts were placed on the wound surface and covered with a dressings and A pliable polyester mesh impregnated with hydrocolloid particles petroleum jelly particles, NOSF particles (Nano-Oligo Saccharide Factor with negative pressure dressing; after seven days, the dressing was removed. Results / Discussion: We treated 20 patients with various underlying morbidities and co-morbidities; in 85 % of the cases, there was an excellently ingrown of the punch Grafts. In 15%, we observed no signs of wound healing or ingrown of the punch grafts. The negative pressure dressing was well tolerated in 100% of the patients. Conclusion: We can conclude that this punch graft biopsy procedure is an easy and well tolerated procedure for patients with various conditions and speed up the wound healing process significantly which will save costs and improves the quality of life.

Background: The use of palladium (Pd) is increasing in metal objects after the banning of nickel in items in prolonged contact with the skin. The properties of Pd make this metal useful in various industrial fields., Objective: The aim of the study was to evaluate the prevalence of Pd sensitization in patients who underwent patch tests for suspected allergic contact dermatitis in the Triveneto region from 2013 to 2018., Methods: A total of 4816 patients with symptoms and/or signs of suspected contact allergic dermatitis were patch tested. Individual characteristics were assessed using a standardized questionnaire., Results: The overall prevalence of Pd sensitization was 7.6% and 10.8% using PdCl2 1% or 2% petrolatum, respectively, with a higher prevalence in women (odds ratio, 2.6; 95% confidence interval, 1.9-3.7) and in 26- to 55-year-old patients. Monosensitization occurred in 1%-1.5% of the patients tested. Health care workers and technicians were more sensitized to Pd than clerks, but the data did not reach statistical significance., Conclusions: Palladium sensitization was high, but it was mainly associated with nickel sensitization. A possible occupational role was found for workers with potential contact with Pd-containing objects, but more data are needed to reach statistical significance., Competing Interests: The authors have no funding or conflicts of interest to declare., (Copyright © 2021 American Contact Dermatitis Society.
