Iatrogenic laser complications.

Modern aesthetic laser technology treatment options offer minimally invasive, more affordable alternatives to traditional cosmetic surgery, with the promise of reduced downtime for the patient. Laser therapy can significantly improve the appearance of the skin; however, these procedures also carry potential risks. This contribution will provide a brief overview of current treatment modalities and review potential complications.

Complications and their management in cosmetic dermatology.

Current aesthetic dermatology rejuvenation options offer minimally invasive, more affordable alternatives to traditional cosmetic surgery. Chemical peels and laser resurfacing can significantly improve the appearance of the skin and stimulate neocollagenesis; botulinum toxin reduces the appearance of dynamic facial lines; and dermal fillers can restore facial fullness. These nonsurgical procedures also carry potential risks.

Complications of soft tissue augmentation.

The wide variety of dermal fillers presently available has revolutionized treatment options for patients seeking a refreshed appearance. Soft tissue fillers include both bovine and human collagens, the hyaluronans, calcium hydroxyapatite, poly-L-lactic acid, and synthetic polymers. However, soft tissue augmentation is never risk-free, and as these procedures have increased in prevalence, complications have been more frequently reported.

Laser treatment of pediatric vascular lesions: Port wine stains and hemangiomas.

Pediatric vascular lesions can be medically threatening and psychologically distressing to patients. This article reviews literature on the laser treatment of two common pediatric vascular lesions, port wine stains and hemangiomas. The purpose of this report was to distinguish the lesions from one another and to present the advantages, disadvantages, complications, and limitations of laser treatment for each lesion type.

Delayed presentation of impending necrosis following soft tissue augmentation with hyaluronic acid and successful management with hyaluronidase.

Soft tissue augmentation is a key element in the successful management of facial rhytids and scars. Injection of hyaluronic acid gels into the dermis is generally well-tolerated with only minimal side effects. Injection necrosis is a rare but clinically significant side effect.

Soft tissue augmentation.

Recent additions to the soft tissue augmentation armamentarium have greatly increased the dermatologic surgeon's choices in optimizing facial contouring and the treatment of acne scars. In this article, we review the science of fillers and look at the future of dermal fillers.

Management of injected hyaluronic acid induced Tyndall effects.

Background And Objectives: Soft tissue augmentation represents a cosmetic procedure performed with increasing frequency.

Study Design/materials And Methods: Correct utilization permits precise correction of facial rhytids and scars. Novice injectors occasionally inject too superficially in tissue with the resultant appearance of discoloration secondary to the Tyndall effect.

Superficial skin resurfacing.

Options for both the cosmetic surgeon offering and patients seeking treatment for cutaneous aging have expanded greatly in recent years and continue to grow. Increasingly sophisticated aesthetic patients are seeking procedures to rejuvenate in record numbers,but many are unwilling to tolerate a large amount of downtime. In expert hands, ablative laser resurfacing has a long history of dramatic results for the treatment of cutaneous aging.

Nonablative resurfacing.

In expert hands, ablative laser resurfacing has a long history of excellent results in the treatment of photodamage-induced rhytids, depressed acne scars, and other signs of cutaneous aging. Over the last decade there have been a growing number of reports in the emerging area of nonablative resurfacing. Nonablative modalities provide less impressive clinical results for rhytid reduction but have shown particular promise for the treatment of scars and superficial dyschromias.

Neonatal pemphigus foliaceus.

The term "pemphigus" refers to a group of diseases that are characterized by the presence of cutaneous or mucosal blisters and erosions, and antiepidermal autoantibodies. There are several case reports of neonatal pemphigus vulgaris in the literature. Although pemphigus foliaceus antibodies have been shown to cross the placenta, to our knowledge, this is only the second reported case of neonatal pemphigus foliaceus.

Lasers, light, and acne.

Acne vulgaris is a highly prevalent disease with significant potential for physical and emotional scarring. Acne lesions have long been noted to improve after exposure to sunlight. This improvement may be secondary to activation of endogenous porphyrins produced by Propionibacterium acnes.

Single-pass CO2 laser skin resurfacing of light and dark skin: extended experience with 52 patients.

Background: Multiple-pass carbon dioxide (CO2) laser skin resurfacing has been a favored treatment modality for photodamaged and acne-scarred skin over the past several years. Its association with numerous side effects and complications, particularly prolonged erythema and dyspigmentation, however, has dampened the initial enthusiasm reserved for its use. By reducing the laser-associated tissue ablation depth and degree of thermal necrosis, it is possible that the incidence of these side effects can also be reduced.

Severe cutaneous reactions associated with the use of human immunodeficiency virus medications.

Patients infected with human immunodeficiency virus are highly susceptible to adverse dermatological reactions to specific medications. Severe cutaneous conditions such as Stevens-Johnson syndrome and toxic epidermal necrolysis are associated with high morbidity and, notably for toxic epidermal necrolysis, high mortality. Although overall mortality from human immunodeficiency virus has dramatically declined owing to highly active antiretroviral therapy, these antiretroviral regimens have been associated with a wide spectrum of severe cutaneous reactions.

Cutaneous tuberculosis: diagnosis and treatment.

As we move into the 21st century, cutaneous tuberculosis has re-emerged in areas with a high incidence of HIV infection and multi-drug resistant pulmonary tuberculosis. Mycobacterium tuberculosis, Mycobacterium bovis, and the BCG vaccine cause tuberculosis involving the skin. True cutaneous tuberculosis lesions can be acquired either exogenously or endogenously, show a wide spectrum of morphology and M.
