Complications of Subcision for Acne Scarring: Experience From Clinical Practice and Review of the Literature.

Background: Subcision is a surgical technique frequently used in the management of atrophic acne scars. The advent of new instruments, which includes sharp, blunt and energy assisted, have increased the efficacy of the procedure. The aim of this article was to review the safety of subcision in view of the new development in technology.

Expert Consensus on Clinical Recommendations for Fractional Ablative CO Laser, in Facial Skin Rejuvenation Treatment.

Background: For three decades, fractional ablative CO lasers have been used for skin rejuvenation. With breakthroughs in laser technology and expanding popularity, new recommendations and suggestions arise on a regular basis.

Objective: To develop up-to-date clinical recommendations on safety measures, therapeutic framework, and techniques to improve treatment outcomes.

Corrosion of copper nickel titanium archwire in chlorhexidine, sodium fluoride, and chitosan mouthwashes.

Background: Copper (Cu), nickel (Ni), chromium (Cr) ion release, and surface topography change from the orthodontic wire are the initial processes of corrosion that may affect the mechanical properties of the archwire. In this study, we aim to evaluate the effect of CHX, NaF, and chitosan on the corrosion of CuNiTi wire nickel and copper ions released, surface roughness change, and archwire deflection.

Methods: Ninety samples of CuNiTi Tanzo™ archwires were divided into five groups according to their immersion solution: Artificial Saliva, CHX, NaF, CHX-NaF, and chitosan group.

Surgical Subcision for Acne Scars: A Review of Instrumentation.

Background: Subcision is a surgical technique for managing atrophic acne scars. Over time, new instruments have emerged to increase the efficiency, efficacy, and safety of the subcision procedure, including sharp, blunt, and energy-assisted devices.

Objective: To review the instrumentation used for the subcision of acne scars and to provide clinicians with practical information regarding the selection of instrumentation, with a focus on advantages and disadvantages.

Chemical peels for atrophic acne scarring: Evolution of peel types and methods.

Acne vulgaris is a common condition among those of adolescent age. Prolonged inflammation associated with the disease can result in substantial scaring which is detrimental to both the physical and psychological well-being of the patient. Chemical peels are a commonly used treatment modality for acne scarring that is widely available and can be administered with a low associated cost.

Trichloroacetic Acid Paint for Boxcar and Polymorphic Acne Scars.

Background: Scarring is a common complication of acne vulgaris with a significant impact on the psychological well-being of patients. Focal application of high concentration trichloroacetic acid (TCA) has been proven efficacious in treating ice-pick scars, but the utility in other scar types is understudied.

Objective: The aim of this study is to evaluate the efficacy and safety of 90% TCA in boxcar and polymorphic acne scars using a novel brush applicator.

O'Brien's actinic granuloma in association with prolonged doxycycline phototoxicity.

O'Brien's actinic granuloma is clinically characterized by annular papules and plaques on sun-exposed areas of skin. These lesions often occur insidiously on a background of severe solar elastosis; however, an acute variant following sunburn has been reported in the literature. We present two cases of acute actinic granuloma precipitated by episodes of sunburn occurring on a background of prolonged doxycycline phototoxicity.
