Dermal suture only versus layered closure: A randomized, split wound comparative effectiveness trial.

BACKGROUND: Layered closure of cutaneous wounds is a commonly used surgical practice. However, there are studies that suggest the additional layer of epidermal sutures might not be necessary. OBJECTIVE: To compare scar outcomes between the single-layer deep-dermal suture technique and the conventional layered suture technique for primary closure of cutaneous wounds. METHODS: A total of 49 patients were enrolled in a prospective, randomized, evaluator-blinded, split scar study to compare the conventional bilayered closure technique with the single-layer deep-dermal suturing technique for primary closure of wounds. The primary outcome measure was mean sum Patient and Observer Scar Assessment Scale (POSAS) score at 3 and 12 months. RESULTS: At the 3-month follow-up, there was a statistically significant difference in the mean total POSAS scores for both the blinded observer and patients, indicating a preference for the side with the standard layered closure. However, at the 12-month follow-up, this difference was lost, with the exception of scar color, which was significantly more noticeable on the wound side closed with only dermal sutures. LIMITATION: Single-center study. CONCLUSION: Three months after surgery, the layered closure technique resulted in a slightly better scar outcome than the single-layered closure containing only dermal sutures. At 12-months' follow-up, this difference diminished, with scars for both sides appearing similar.

Desmoplastic intradermal spitz nevi arising within red tattoo ink.

Tattoos present a diagnostic challenge for dermatologists. Various reactions to tattoo have been identified in the literature ranging from allergic, to infectious, to neoplastic. Of the neoplastic cases identified, it is unclear whether the tattoo ink was directly causative, or if the cases were merely coincidence, as the number of cutaneous malignancies has also been on the rise. We present a novel case of two desmoplastic intradermal Spitz nevi arising within red tattoo ink.

Single-Staged Tunneled Cheek Interpolation Flap With Cartilage Batten Graft for Repair of Nasal Ala Defect.

Surgical defects located within 5 mm of the nasal alar margin are at risk for alar elevation or collapse of the external nasal valve during wound healing. To reduce the chance of such complications, free cartilage grafts may be used as part of the reconstruction. However, if the defect is large enough so that the free cartilage graft does not fill most of the defect, wound contraction can still lead to alar displacement. In these situations, skin may need to be recruited from either the forehead or cheek in the form of an interpolation flap to cover both the free cartilage graft and the residual cutaneous defect. Typically, such reconstructions require multiple procedures at separate time periods and pose prolonged wound care and an inconvenience to the patient. We describe a case of a 94-year-old male who desired an aesthetic reconstruction of a large nasal alar defect that required only a single operative visit. To simplify the repair into a one-stage procedure, a tunneled cheek interpolation flap was performed over a free cartilage graft.

Multiple labial melanotic macules occurring after topical application of calcineurin inhibitors.

Topical calcineurin inhibitors are widely used to treat inflammatory dermatoses for their steroid-sparing advantage. Herein, we report a patient with chronic lip dermatitis who developed multiple labial melanotic macules after application of tacrolimus 0.1% ointment and pimecrolimus 1% cream. Prior and current reports raise concerns for potential development of pigmented lesions associated with topical calcineurin inhibitor use. These reports highlight the need for careful risk-benefit assessment when prescribing topical calcineurin inhibitors for inflammatory dermatoses, especially when used on sun-exposed sites.

Porcine xenograft and second intention healing on the lower extremities after Mohs surgery: a descriptive case series.

There is limited data on benefits of healing after Mohs surgery using porcine xenografts (PXs) compared to second intention (SI). This case series sought to describe healing time, scar size, cosmetic outcome, pain, and infection rates in patients treated with PX or SI for wounds on lower extremities. 14 patients were enrolled. Six patients received treatment with SI, and eight patients received PX. 11 patients (4 SI, 7 PX) completed follow-up visit after 3 months (79% follow-up rate) when primary outcome measure was assessed. 64% of patients took > 3 months to heal. 72% of patients healed within 6 months post-surgery. Scars contracted by > 50% in 7/11 patients completing follow-up. In SI group, 3/5 patients self-reported pain level > 1 out of 10 at 1-week post-surgery compared to 3/8 in the PX group. Two patients in each group developed post-operative wound infection and three patients in PX group experienced other adverse events. These results suggest that healing with PX or SI resulted in small scar size, low post-operative pain level, and low rate of adverse events. Both groups had longer healing times than expected.
