Development of a core outcome set for basal cell carcinoma.

Background: There is variation in the outcomes reported in clinical studies of basal cell carcinoma. This can prevent effective meta-analyses from answering important clinical questions.

Objective: To identify a recommended minimum set of core outcomes for basal cell carcinoma clinical trials.

Development of a core outcome set for cutaneous squamous cell carcinoma trials: identification of core domains and outcomes.

Background: The lack of uniformity in the outcomes reported in clinical studies of the treatment of cutaneous squamous cell carcinoma (cSCC) complicates efforts to compare treatment effectiveness across trials.

Objectives: To develop a core outcome set (COS), a minimum set of agreed-upon outcomes to be measured in all clinical trials of a given disease or outcome, for the treatment of cSCC.

Methods: One hundred and nine outcomes were identified via a systematic literature review and interviews with 28 stakeholders.

Core Outcome Set for Actinic Keratosis Clinical Trials.

Importance: Although various treatments have been found in clinical trials to be effective in treating actinic keratosis (AK), researchers often report different outcomes. Heterogeneous outcome reporting precludes the comparison of results across studies and impedes the synthesis of treatment effectiveness in systematic reviews.

Objective: To establish an international core outcome set for all clinical studies on AK treatment using systematic literature review and a Delphi consensus process.

Ossifying fibromyxoid tumor of soft parts presenting as a scalp cyst.

Background: Ossifying fibromyxoid tumor of soft parts (OFMT) is a rare mesenchymal neoplasm of intermediate malignant potential. The tumor most commonly occurs on the extremities with a male predominance. We present an unusual case of OFMT occurring as a cystic lesion on the scalp of a female.

Repair of defects on nasal sebaceous skin.

Background: Reconstructive procedures performed on sebaceous nasal skin are prone to partial flap necrosis, scar spread and inversion, and tissue mismatch. An ideal repair would optimize vascular integrity, minimize closure tension, and use adjacent tissue.

Objective: The purpose of this article is to describe a flap design and dynamics that permit satisfactory reconstruction of small- to medium-sized defects on nasal sebaceous tissue.

Srcasm modulates EGF and Src-kinase signaling in keratinocytes.

The Src-activating and signaling molecule (Srcasm) is a recently described activator and substrate of Src-family tyrosine kinases (SFKs). When phosphorylated at specific tyrosines, Srcasm associates with Grb2 and p85, the regulatory subunit of phosphoinositide 3-kinase; however, little is known about the role of Srcasm in cellular signaling. Data presented here demonstrate that epidermal growth factor (EGF) receptor ligands promote the tyrosine phosphorylation of endogenous and adenovirally transduced Srcasm in keratinocytes, and that increased levels of Srcasm activate endogenous SFKs, with a preference for Fyn and Src.

Gene expression profiling of porokeratosis demonstrates similarities with psoriasis.

Background: Porokeratosis (PK) is a clinically heterogeneous entity associated with sharply demarcated, annular, or serpiginous lesions with a hyperkeratotic ridge. This disorder is associated with aberrant keratinocyte differentiation that histologically manifests as a stack of parakeratin termed the cornoid lamella; this structure represents the peripheral hyperkeratotic ridge of clinical lesions. Histologically, the keratinocytes forming the cornoid lamella demonstrate an altered differentiation program.

A dorsal nasal advancement flap for off-midline defects.

Background: The repair of nasal tip defects often poses a challenge as many of the commonly used techniques for repair of the distal nose can result in obvious scars, mismatched skin, or distortions of the nasal contour that can compromise the aesthetic outcome.

Objective: Our aim was to create a novel nasal tip flap and examine outcomes of its use.

Methods: The dorsal nasal advancement flap was studied in 30 patients.

Aging of the skin: implications for cutaneous surgery.

There are precious few benefits, save perhaps experience and wisdom, that those of advanced age may claim over those who continue to dwell in their youth. One somewhat paradoxical advantage, however, is the ability of older patients to apparently heal better than younger patients after cutaneous surgery. In older patients, the incision lines are less red, the scarring is less hypertrophic, and "normalization" of appearance occurs more rapidly.

Nasal reconstruction with the cheek island pedicle flap.

Background: Reconstruction of the lower third of the nose can be challenging. Maintaining the nasal subunit symmetry and providing good tissue match with regard to color, sebaceous quality, and thickness is essential. For extensive defects in this area, paramedian forehead flaps are often considered.

Treatment of photodamaged skin with trichloroacetic acid and topical tretinoin.

Background: Photodamaged skin typically displays lentigines, actinic keratoses, wrinkles, and textural alteration. Chemical peeling has been used to treat these, but few controlled studies have been performed to determine its efficacy.

Objective: Our purpose was to compare the efficacy of a medium-depth chemical peel with and without tretinoin before and after treatment.

Conchal bowl skin grafting in nasal tip reconstruction: clinical and histologic evaluation.

Background: It is often difficult to achieve an esthetically pleasing cosmetic match when full-thickness skin grafts from periclavicular, preauricular, or postauricular donor sites are used to repair distal nasal defects. This, in large part, is due to the highly sebaceous nature of the skin on the distal aspect of the nose.

Objective: Our purpose was to describe the benefits of using donor skin from the conchal bowl to repair defects of the nasal tip.

The isolated frontal forelock.

Background: The progression and extent of male pattern baldness is statistically unpredictable.

Objective: An approach to the patient with male pattern baldness is suggested, which results in a product that changes appearance in a positive way, is natural, requires no maintenance, and does not deconstruct with progression of alopecia.

Methods And Results: A technique is described for transplantation of the frontal forelock allowing creation of a soft anterior zone and a dense posterior component.
