A regional survey of purse-string sutures for partial and complete closure of Mohs surgical defects.

Background: The purse-string suture is a method for partial and complete closure of circular surgical defects.

Objective: Short-term and long-term efficacy and cosmesis were assessed to evaluate the utility of purse-string closure as the sole method of closure of Mohs defects in different locations.

Materials And Methods: Sixty-six circular wounds from Mohs surgery were closed with a running intradermal suture traversing the circumference of the wound.

Topical formulation engendered alteration in p53 and cyclobutane pyrimidine dimer expression in chronic photodamaged patients.

While the clinical attributes of photoaging are well characterized in the literature, the pathogenic mechanisms that underlie these changes are incompletely elucidated. At the molecular level, p53 tumor-suppressor gene product mediated excision repair of ultraviolet (UV)-induced DNA damage is a critical effector in xeroderma pigmentosum (XP) and potentially in conventional photoaging. We examined p53 activity and measured UV-induced DNA damage via cyclobutane pyrimidine dimers (CPDs) quantitatively in 20 volunteers before and after an 8-week, open-label prospective topical application of a proprietary DNA recovery serum (Celfix).

Clindamycin phosphate 1.2% and tretinoin 0.025% gel for rosacea: summary of a placebo-controlled, double-blind trial.

Rosacea is a common, chronic, and poorly understood dermatological condition characterized by an inflammatory component composed of papules and pustules and a vascular component composed of flushing and erythema. Current treatment options include topical, systemic, and light-based methods, each of which focuses on either the inflammatory or the vascular component. Retinoids are not routinely indicated as treatment because of the common conception that they would be too inflammatory for the sensitive rosacea patient.

Clearance of invasive melanoma with topical imiquimod.

A 93-year-old woman presented with biopsy-proven invasive melanoma of 2.75 mm depth, arising from a melanoma in situ. Standard treatment of this depth would be an extensive and mutilating excision, which presented a therapeutic dilemma.
