Immediate debridement of road rash injuries with Versajet® hydrosurgery: traumatic tattoo prevention?

Sandblasting Injury: A Case Report and a Review of Literature

Sandblasting injuries are uncommon with only four reports in literature. We report a patient with a sandblasting injury of the dorsum of the hand and wrist and summarise published literature on the management of such injuries. We recommend early (<24 hours) C-arm-guided debridement of embedded foreign bodies and repeated saline washouts with a soft surgical scrub brush. Level of Evidence: Level V (Therapeutic).

The color of skin: blue diseases of the skin, nails, and mucosa

Diseases of the skin, hair, nails and mucosa can appear as flesh-colored lesions or may present as any of the colors of the visual spectrum. Diseases associated with blue (or shades of blue) discoloration represent a unique group of conditions that occur de novo or as a reaction to either a topical or a systemic agent to which the individual has been exposed. Blue diseases can affect the skin, the nails or the mucosal membranes of the mouth (buccal mucosa, gingiva, lips, palate or tongue) or eyes (sclera). In addition to appearing blue, they can also appear as blue-black, blue-brown, blue-gray, blue-green, blue-purple, blue-red, and blue-silver. The conditions range from those secondary to exogenous agents (systemic or tattoo or topical) to syndromes to systemic diseases to tumors (adnexal, melanocytic, vascular, or miscellaneous). A comprehensive attempt to include all conditions that have been described as blue (or a shade of blue) has been performed by evaluating the following terms using the medical search engine PubMed: blue and either gingiva, lips, lunula, mucosa, nails, oral, palate, sclera, skin, or tongue. Subsequently, the conditions were organized by color (blue and shades of blue) and within each color by location (skin, nails, oral mucosa and sclera). The results are presented in organized tables; in addition, there is discussion of some of the conditions that are unique to one or more specific locations. In conclusion, 'preserve and cherish the pale blue dot' and remember that a big red rock eater with chrysiasis is the answer to the riddle, "What is big and blue and eats rocks?"

Hydroconductive and silver-impregnated foam dressings: a comparison

OBJECTIVE

As the number of commercially available wound dressings is increasing rapidly, it is important for clinicians to understand the strengths and limitations of each and to recognise relationships between wound type and dressing properties to obtain optimal healing results. Our aim is to test the antimicrobial activity of two dressings.

METHOD

A hydroconductive (HC) dressing and a silver-impregnated foam (SIF) dressing were compared for their potential to reduce the levels meticillin-resistant Staphylococcus aureus (MRSA). We also assessed MRSA-derived biologically active components in liquid or agar matrices, simplified models for heavily exuding or dry wounds respectively, and in an in vivo animal model with MRSA infected wounds.

RESULTS

In the agar model (dry wounds) both dressings showed a strong reduction in MRSA activities within 24 hours post-application. The antibacterial effects of the SIF dressing were more pronounced in the liquid model, however, at an increasing cytotoxic cost. In agreement with these in vitro results, assessment of dressings using an MRSA-infected wound in an rat model showed a decrease in MRSA which was significant 7 days post-burn and inoculation, with more compromised viability of MRSA. Dressings showed a similar capability to reduced and eliminate toxic shock syndrome toxin (TSST-1) at day 7 post-burn in the animal model but not at day 4, where the SIF dressing was more potent Conclusion: These results confirm the advantages of using silver in reducing bacterial load in wound treatment, except for conditions of highly exuding wounds where the cytotoxic properties of silver may offset these advantages and HC dressing use is more suitable.

Effective prevention of posttraumatic tattoo using hydrosurgical debridement in the ED

Traumatic tattoos can result from the accidental deposition of foreign particles in the dermis. These pigmented particles can become permanently lodged in the dermis after wound re-epithelialization and lead to irregular black or blue skin discoloration. Different methods exist for tattoo removal. The best strategy is to prevent traumatic tattoo formation by immediately removing the foreign particles before the healing process begins. Here, we present a fine-tuned, hydrosurgical debridement system to selectively debride wounds and preserve as much viable tissue as possible.
