Papular acne scars are skin-colored or hypopigmented, soft and elevated lesions of the chin and trunk. Papular scars are one of the most difficult acne scars to treat. Herein, we reported two patients with papular acne scars on the chin that were successfully treated by the pinhole method using an Erbium (ER):YAG laser. Good cosmetic results were achieved in both patients. The side effects included mild, intra-, and post-procedural pain and erythema that resolved spontaneously within 2 weeks. The pinhole method with an Er:YAG laser could potentially be used as a safe and effective treatment for papular acne scars...

Acne is a chronic disease of the pilosebaceous units, presenting as inflammatory or noninflammatory lesions, affecting primarily the face but also the back and chest. The mainstay of treatment remains topical retinoids, benzoyl peroxide, azelaic acid, antibiotics, and isotretinoin, many of which result in poor compliance, lack of durable remission, and incur adverse effects. The use of lasers to treat acne is continuously increasing because of their minimal complications, limited number of office-based treatments required, potential benefits of simultaneously treating acne scarring, and the rapid onset of results...

The molecular changes in gene expression following ablative laser treatment of skin lesions, such as atrophic scars and UV-damaged skin, are not completely understood. A standardized in vitro model of human skin, to study the effects of laser treatment on human skin, has been recently developed. Therefore, the aim of the investigation was to examine morphological and molecular changes caused by fractional ablative erbium:YAG laser treatment on an in vitro full-thickness 3D standardized organotypic model of human skin...

Treatment of disseminated superficial actinic porokeratosis (DSAP) is poorly standardized. The present review seeks to comprehensively discuss the potential for laser and light modalities in the treatment of DSAP. A systematic review of light and laser treatment modalities was conducted to include 26 cases of patients with DSAP. Systematic review resulted in 14 articles to be included. Photodynamic therapy (PDT) overall was the least successful treatment modality, with clinical improvement seen in a minority of patients (MAL-PDT: N = 9 patients, 33...

BACKGROUND: Treatment of congenital melanocytic nevi (CMN) with intense pulsed light (IPL) has recently produced promising results. OBJECTIVE: To evaluate the clinical and histological outcomes of small-to-medium sized CMN treated with IPL alone and in combination with erbium: yttrium-aluminum-garnet (Er: YAG) laser. METHODS: We performed a retrospective chart review of 26 small-to-medium sized CMN treated as described above. The reduction in visible pigmentation, signs of recurrence and any adverse skin changes were evaluated by two independent clinicians...

The objective of this pilot study was to determine the safety and efficacy of a new non-ablative erbium YAG laser procedure for the treatment of type III stress urinary incontinence (intrinsic sphincter deficiency) in women. Twenty-two patients with a Valsalva leak point pressure less than 60 cm H2O were recruited and treated with a non-ablative erbium laser delivering low fluence pulses inside the whole length of the urethra through a specially designed cannula. Treatment consisted of two treatment sessions with a 3-week interval in-between...

Laser-assisted drug delivery has generated intense interest. The objectives of this study are to evaluate the clinical benefit of laser-assisted corticosteroid delivery and to compare this technique to corticosteroid intralesional injection, a standard treatment for keloids. Patients with keloids on the left shoulder after BCG vaccination were enrolled in this study. The entire lesion was first treated with an ablative fractional erbium-YAG laser. After this treatment, the lesion was divided into two halves...

OBJECTIVE: The purpose of this study was to evaluate the effects of laser and acid etching on the mineral content and photon interaction parameters of dental enamel in human teeth. BACKGROUND DATA: The composition of dental enamel may vary, especially at the surface, depending on the reactions that occur during dental treatment. MATERIALS AND METHODS: Forty maxillary premolars were divided randomly into 2 groups of 20 teeth. In the first group, half of teeth crowns were etched by using 37% phosphoric acid; in the second group, half of teeth crowns were etched by using an erbium:yttrium-aluminum-garnet (Er:YAG) laser...

PURPOSE: To histologically evaluate the efficacy of sodium hypochlorite (NaClO) in combination with Er:YAG (erbium-doped yttrium aluminium garnet) laser in dissolving necrotic tissue and cleaning root canals as well as canal isthmuses. METHODS: After scanned by cone-beam CT (CBCT), 50 well-prepared premolars with root canal isthmuses were selected and randomly assigned into 5 groups. They were subsequently subjected to different regimens as followed: group A-irrigated with 1% NaClO for 1 minute, group B- irradiated by Er:YAG laser at 0...

Keratoacanthoma (KA) is a subtype of squamous cell carcinoma whose development has been linked to excessive sun exposure, immunosuppression, and trauma. Given the rapidly expanding therapeutic armamentarium for anti-aging modalities in dermatology, reports of KA secondary to invasive cosmetic procedures are on the rise. We present a case of eruptive KAs after full- eld ablative Erbium:YAG 2940 nm laser resurfacing of the face that resolved with minimal intervention. This case demonstrates the potential for a rare yet signi cant laser complication that may warrant discussion during the consenting process...

Medication-related osteonecrosis of the jaws (MRONJ) is an adverse side effect of several drug therapies, including bisphosphonates (BPs). Osteonecrosis of the jaw specifically related to BP therapy is usually referred to using the acronym BRONJ. However, no consensus has yet been reached regarding the most appropriate management of BRONJ. The greatest success rates have been recorded with surgical removal of necrotic bone. In particular, erbium:yttrium-aluminum-garnet (Er:YAG) laser-assisted surgery has shown significantly better results than conventional surgical approaches...

RANDOMIZED CONTROLLED TRIAL
Mai Abdel Raouf Osman, Hisham Ali Shokeir, Marwa M Fawzy
BACKGROUND: Ablative fractional erbium-doped yttrium aluminum garnet (Er:YAG) laser and microneedling have been popularized in recent years and their effectiveness and side effects individually reported. No previous study, however, has directly compared the efficacy and safety between the 2 different treatments. OBJECTIVE: To compare the efficacy and safety of the ablative fractional Er:YAG laser and microneedling for the treatment of atrophic acne scars. MATERIALS AND METHODS: Thirty patients with atrophic acne scars were randomly treated in a split-face manner with a fractional Er:YAG laser on one side and microneedling on the other side...

The aim of the present study was to compare dynamics of the bone healing process after different types of osteotomies. In total, 24 Wistar rats were subjected to different types of osteotomy performed with standard steel bur, piezosurgery, contact, and non-contact Erbium:yttrium-aluminum-garnet (Er:YAG) laser ablation. The animals were randomly divided into four groups, to be euthanized immediately after the procedure, or at 1, 2, or 3 weeks after surgery. The obtained bone samples were analyzed by scanning electron microscopy (SEM)...
