Background: Fingertip injuries are very common in emergency departments. According to the literature, Allen III and IV fingertip injuries should be treated with local skin flaps. Instead, we have treated these kinds of injuries in recent years with a semi-occlusive dressing. The main purpose of this study was to evaluate the outcome after semi-occlusive dressing therapy with respect to soft tissue cover, recovery of sensibility and duration of disability.
Methods: We retrospectively analysed 77 fingertip injuries (39 Allen I, 25 Allen II, 9 Allen III, 4 Allen IV) from 2008-2011 in 23 women and 54 men who were treated with a semi-occlusive dressing. The mean age was 36 ± 14 years and the mean follow-up was seven months. The bone was not shortened even if the bone was exposed up to the wound level. The primarily occlusive dressing was left as long as possible and was sealed when necessary. Furthermore, the treatment time with the semi-occlusive dressing and the period of disability was recorded. Patient sensitivity recovery was also analysed.
Results: The mean treatment duration was 21 ± 10 days and the mean duration of disability was 30 ± 17 days. The mean duration of disability was 19 ± 8 days for Allen I injuries, 36 ± 16 days for Allen II, 45 ± 20 days for Allen III and 58 ± 7 days for Allen IV. All patients developed satisfactory tissue cover and sensibility recovery. For amputation injuries of Allen III and IV, we recorded a normal light-touch 2‑point discrimination in the Semmes-Weinstein Test in 77 % and diminished in 23 %. There were no complications like tissue infections, neuroma or osteitis. Also, no secondary flap supply was necessary.
Conclusions: The semi-occlusive dressing is a good therapy for all kind of fingertip injuries, regardless of the amputation level. Even if the bone is exposed up to the wound level, satisfactory soft tissue cover can be achieved.

Background: Patients face increasing financial toxicity (FT), defined as emotional distress due to the cost of medical treatment. However, little is known regarding FT in the context of upper extremity trauma.
Methods: We surveyed patients who sustained traumatic finger amputation (October 21, 2011-January 1, 2021).

Objective: The effect of continuous topical oxygen therapy (cTOT) on biofilm gene transcription profiles following inoculation onto porcine skin, using a customised molecular assay was determined.
Method: Sterilised porcine skin explants were inoculated with in triplicate: 0 hours as negative control; 24 hours cTOT device on; 24 hours cTOT device off. The oxygen delivery system of the cTOT device was applied to the inoculated tissue and covered with a semi-occlusive dressing.

Purpose: Since wounds are a primary source of infection, it is desirable to have a wound dressing that prevents infectious processes during the tissue regeneration phase. In this regard, silver nanoparticles, oregano essential oil, and chitosan have been utilized due to their antimicrobial activity. This work focused on the preparation of a composite containing these three components, intended to provide protection for wounds, especially by exerting antimicrobial effects.

Article Synopsis
- The study evaluated a conservative treatment for fingertip injuries with volar pulp defects, using artificial dermis and semi-occlusive dressings.
- Findings showed minimal complications and significant outcomes, including high fingerprint regeneration and low post-treatment pain.
- Patient satisfaction with the treatment's functionality and appearance was notably high, supporting this approach as effective and less invasive.
Formulation and dermal delivery of a new active pharmaceutical ingredient in an in vitro wound model for the treatment of chronic ulcers.

The aim of this study was to investigate dermal delivery of the new active pharmaceutical ingredient (API) TOP-N53 into diabetic foot ulcer using an in vitro wound model consisting of pig ear dermis and elucidate the impact of drug formulation and wound dressing taking into consideration clinical relevance in the home care setting and possible bacterial infection. Different formulation approaches for the poorly water-soluble API including colloidal solubilization, drug micro-suspension and cosolvent addition were investigated; moreover, the effect of (micro-)viscosity of hydrogels used as primary wound dressing on delivery was assessed. Addition of Transcutol® P as cosolvent to water improved solubility and was significantly superior to all other approaches providing a sustained three-day delivery that reached therapeutic drug levels in the tissue.
