Introdução: The increase in the demand for cosmetic procedures has in turn stimulated the search for effective and safe analgesia.Topical anesthetics are an alternative to infiltrative anesthesia, and promote an appropriate analgesia without inducing adverse effects. Objective: To compare the pain ratings of two topical lidocaine formulations in patients undergoing fractional CO2 laser therapy....

one of the basic purposes in dental treatment is providing a painless treatment for patients. this purpose may be achieved by the application of laser in dentistry. low-level laser therapy (lllt) is an internationally accepted title for biomodulation with low-level lasers which we use to achieve ideal therapeutic effects. low-level laser therapy is a painless, reproducible, non-invasive, and wi...

the desire to achieve cosmetic rejuvenation and reduce effects of aging and photodamage urged scientists to develop effectual techniques which have minimal side effects and impressive long-term efficacy. traditional ablative resurfacing laser therapy has been used for several years;however, it has harmful side effects on the patient’s skin such as dyspigmentation, persistent erythema, infection...

Background: Hirsutism is defined as the presence of terminalhairs with a male-like pattern in women, due to the increasedlevels of androgens or increased responses of the target organs toandrogens. Facial hirsutism has a negative effect on the quality oflife in female patients. Among the many therapeutic modalitie...

An analytical model is presented describing the temporal intensity contrast determined by amplified spontaneous emission in high-intensity laser systems which are based on the principle of chirped pulse amplification. The model describes both the generation and the amplification of the amplified spontaneous emission for each type of laser amplifier. This model is applied to different solid stat...

BACKGROUND Elderly people suffer from skeletal muscle disorders that undermine their daily activity and quality of life; some of these problems can be listed as but not limited to: sarcopenia, changes in central and peripheral nervous system, blood hypoperfusion, regenerative changes contributing to atrophy, and muscle weakness. Determination, proliferation and differentiation of satellite cell...

The detection capabilities of both laser and high-intensity quartz arc tubes were evaluated. The Spectra-Physics Model 171-19, 18-W argon ion laser and Laser Sonics Model CS-2, 200-mW air-cooled argon ion laser were compared with Payton Scientific's Luma-Print, high-intensity quartz arc tube. The light sources were evaluated as to their detection limits for various biological stains. The stains...

In this paper, we present the shielding analysis to determine the necessary neutron and photon shielding for a laser-accelerated proton therapy system. Laser-accelerated protons coming out of a solid high-density target have broad energy and angular spectra leading to dose distributions that cannot be directly used for therapeutic applications. A special particle selection and collimation devic...

Rhinophyma is a benign and disfiguring tumor of the nose, affecting white old men. It represents the end stage of acne rosacea. Hypertrophy of the sebaceous apparatus and fibrosis lead to an enlarged, erythematous nasal tip with comedones. Treatment modalities include Isotretinoin (Which is not effective on severe rhinophyma), freehand scalpel shave, cryosurgery, electrocautery, dermabras...
