Comparative Study Between the efficacy of Long-Pulsed Neodymium- YAG Laser and Fractional Co2 Laser in the Treatment of Striae Distensae.

Stretch marks, or striae distensae (SD), are the lesions of the dermis caused by its linear atrophy at the sites of stretching. They occur in more than 70% of pregnant women and adolescents as a result of cutaneous stretching. This study aimed at evaluating and comparing the clinical and histological efficacy of the fractional CO laser versus the long pulsed (LP) Nd: YAG laser in the treatment of striae alba.

Automated Microneedling Versus Fractional CO2 Laser in Treatment of Traumatic Scars: A Clinical and Histochemical Study.

Background/objectives: Microneedling has shown satisfactory effects in scar rejuvenation. Comparisons of its results with fractional laser are limited. This study aims to compare the efficacy and safety of automated microneedling versus fractional carbon dioxide (CO2) laser in treatment of traumatic scars on clinical and histochemical bases.

Pulsed dye laser alone versus its combination with topical ivermectin 1% in treatment of Rosacea: a randomized comparative study.

Background: While the etiology of rosacea is multifactorial, it is not surprising that treatment has been controversial. Pulsed dye laser (PDL) has been successfully used to treat vascular components of rosacea. Ivermectin 1% cream is an emerging treatment of rosacea.

Fractional Erbium-Doped Yttrium Aluminum Garnet Laser Versus Microneedling in Treatment of Atrophic Acne Scars: A Randomized Split-Face Clinical Study.

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.

Comparison of the effectiveness of two fluences using long-pulsed Nd:YAG laser in the treatment of striae distensae. Histological and morphometric evaluation.

Striae distensae are common undesirable skin lesions of significant aesthetic concern. To compare the efficacy of two fluences (75 and 100 J/cm) of long-pulsed Nd:YAG laser in the treatment of striae. Forty-five patients (Fitzpatrick skin types III-V) aged between 11 and 36 years with striae (23 patients with rubra type and 22 with alba type) were enrolled in the study.

Treatment of genital warts in males by pulsed dye laser.

Objective: To determine the safety and efficacy of the flashlamp-pumped pulsed dye laser for the treatment of uncomplicated genital warts in adult males.

Methods: This was a prospective observational study set in the outpatient clinics of the Department of Andrology and Sexually Transmitted Diseases, National Institute of Laser Enhanced Sciences, the Dermatology Clinic, Cairo University, and the Department of Dermatology and Venereology, Suez Canal University. A total of 174 adult male patients with 550 uncomplicated anogenital warts were included.

Study of solar photosensitization processes on dermatophytic fungi.

The antifungal activity of solar simulator was evaluated in presence of haematoporphyrin derivative (HPD), methylene blue (MB) and toluidine blue O (TBO) as photosensitizers. Seven dermatophytes were used as test fungi. The solar simulator at fluence rate 400 W/m2 for 30 minutes induced marked inhibition for spore germination of the photosensitized fungi.
