low-level laser therapy and hypertrophic

Jehan Alsharnoubi, Omnia Mohamed
The management of burn scars has become one of the major clinical challenges in the developing countries which involve enormous treatment cost; this needs new methods for better cost benefit relationship. The objective of the study is to analyze the effectiveness of low-level laser therapy on post-burn scar tissue in children. A randomized controlled study included 15 children, ranging from 2 to 10 years of age, presenting with burn scars. They received diode laser and topical treatment. Each scar was divided into two halves...

In this study, we aimed to quantify the effects of fractional ablative carbon dioxide laser therapy in the treatment of widespread hypertrophic burn scars. While many different pilot studies have described the potential of the technology and expert groups and current guidelines, alike, recommend its use, the level of evidence for the efficacy of fractional CO2-laser treatment for burn scars is currently very low. Ten patients (three male, seven female) with hypertrophic burn scars were treated with a single course of fractional CO2-laser therapy in an in-patient controlled setup, using a standardized treatment paradigm...

BACKGROUND: Scars represent the visible sequelae of trauma, injury, burn, or surgery. They may induce distress in the patient because of their aesthetically unpleasant appearance, especially if they are excessively raised, depressed, wide, or erythematous. They may also cause the patient symptoms of pain, tightness, and pruritus. Numerous products are marketed for scar prevention or improvement, but their efficacy is unclear. METHODS: A literature review of high-level studies analyzing methods to prevent or improve hypertrophic scars, keloids, and striae distensae was performed...

BACKGROUND: Because acne scarring is associated with substantially reduced quality of life, early initiation of effective treatment is desirable. In previous reports, isotretinoin treatment was associated with increased scarring after cosmetic procedures, such as laser treatment, dermabrasion, and chemical peeling. OBJECTIVE: To evaluate wound healing after ablative carbon dioxide (CO2) fractional resurfacing for acne scarring conducted during and/or within 1 to 3 months of oral isotretinoin treatment...

BACKGROUND AND AIMS: Hypertrophic scar is a form of abnormal wound healing process in which tissue repair regulating mechanism is disrupted. Transforming growth factor β1 has a particular importance in the fibrotic scarring response. Treatment of hypertrophic scar included many chemical, physical, and surgical options. Fractional CO2 laser devices have gained acceptance as a way for managing hypertrophic scar. Aims of this study are: (a) to determine the clinical and histopathological effects of fractional CO2 laser on hypertrophic scar, (b) to evaluate the expression pattern of transforming growth factor-β1 (TGF-β1) as an important fibrogenic factor before and 6 months after fractional CO2 laser treatment...

Pulsed dye laser (PDL) treatment is well established and has been reported to be safe and effective in the management of superficial hemangiomas, port-wine stains, and other vascular lesions. Although hyperpigmentation is quite common, other side effects such as hypopigmentation, ulceration, hemorrhaging, atrophic scarring, and hypertrophic scarring are rare. We report the case of a 42-year-old woman who developed atrophic scarring of the nasal alae following cosmetic PDL treatment. Patients receiving PDL treatment should be warned about the risk for the development of scarring...

Keloids and hypertrophic scars occur anywhere from 30 to 90% of patients, and are characterized by pathologically excessive dermal fibrosis and aberrant wound healing. Both entities have different clinical and histochemical characteristics, and unfortunately still represent a great challenge for clinicians due to lack of efficacious treatments. Current advances in molecular biology and genetics reveal new preventive and therapeutical options which represent a hope to manage this highly prevalent, chronic and disabling problem, with long-term beneficial outcomes and improvement of quality of life...

IMPORTANCE: Fractionated, ultrapulsed carbon dioxide (CO2) laser therapy is a powerful tool for the treatment of scars. Common adverse effects of this therapeutic modality have been previously documented. We describe 2 unreported adverse effects of ultrapulsed CO2 laser treatment of mature scars in a patient previously treated with silver-impregnated dressings. OBSERVATIONS: A teenage survivor of toxic epidermal necrolysis presented with faint but diffuse dyschromia clinically and histologically consistent with localized argyria secondary to silver-impregnated dressings used years earlier...

Low-level laser (light) therapy (LLLT) is a fast-growing technology used to treat a multitude of conditions that require stimulation of healing, relief of pain and inflammation, and restoration of function. Although skin is naturally exposed to light more than any other organ, it still responds well to red and near-infrared wavelengths. The photons are absorbed by mitochondrial chromophores in skin cells. Consequently, electron transport, adenosine triphosphate nitric oxide release, blood flow, reactive oxygen species increase, and diverse signaling pathways are activated...

Noninvasive body contouring has become one of the fastest-growing areas of esthetic medicine. Many patients appear to prefer nonsurgical less-invasive procedures owing to the benefits of fewer side effects and shorter recovery times. Increasingly, 635-nm low-level laser therapy (LLLT) has been used in the treatment of a variety of medical conditions and has been shown to improve wound healing, reduce edema, and relieve acute pain. Within the past decade, LLLT has also emerged as a new modality for noninvasive body contouring...

Different lasers are used to improve scars in combination with other therapies. The pulsed dye laser is considered to be the gold standard for hypertrophic scars and keloids. Ablative laser treatments are used with atrophic scars. Ablative or non-ablative fractional laser treatments are developing rapidly due to the lower risk of infection and easier follow-up care.

INTRODUCTION: Osteogenesis distraction (OD) is a mainstream technique in maxillofacial surgical reconstruction with varied applications. OD technique employs a distractor with the aim to get new bone in the site of interest. Osseous maturation time is necessary before the device can be removed and few patients' complaint of related discomfort, especially when these devices are external, and induces superficial infections, paresthesia, hypertrophic scars and social relationship difficulties...

Keloids and hypertrophic scars are common lesions, which typically present as a cosmetic concern; however, they also can cause significant pruritus and pain. These lesions pose as a particular therapeutic challenge among clinicians due to a lack of complete knowledge of the formation of keloids and hypertrophic scars. Multiple treatments are widely accepted, yet all have shown limited benefit. In this case, we describe the treatment combination of the Affirm CO2 fractional laser (10 600 nm, Cynosure), Cynergy Pulsed dye laser (585 nm, Cynosure), and triamcinolone acetonide injection for keloids refractory to solitary treatments of triamcinolone acetonide injection and other laser modalities...
