Association of Diet With Skin Histological Features in UV-B-Exposed Mice.

Importance: Long-term exposure to solar radiation produces deleterious photoaging of the skin. It is not known if diet can influence skin photoaging.

Objectives: To study the influence of a calorie-restricted diet and an obesity diet in mice exposed to long-term UV-B irradiation to assess if there is an association between diet and histopathological response to UV-B irradiation.

Beauty in a multicultural world.

The increased demand for facial cosmetic surgery has come from a more diverse, informed, and selective patient population from all walks of life. Virtually no two patients have the same background or cosmetic objectives. However, the classic tenets of beauty including phi, symmetry, averageness, youthfulness, and sexual dimorphism can be applied to persons of all ethnicities to assist in objectifying the abstract concept.

Outcomes of intubation in difficult airways due to head and neck pathology.

The purpose of this study was to examine the impact of surgical pathology, anesthesiologist experience, and airway technique on surgically relevant outcomes in patients identified by preoperative laryngoscopy to have a difficult airway due to head and neck pathology. We prospectively recorded a series of 152 difficult airway cases due to head and neck pathology out of 2,145 direct laryngoscopies undertaken between November 2005 and June 2008. One of two senior anesthesiologists specializing in head and neck procedures intubated 101 (66.
