Validation Of Non-contact Technique For Local Skin Temperature measurements

Here we propose to quantify local temperature variations using thermal imaging to assess the effect of dermatological lasers.

OBJECTIVES:
To quantify the temperature raise induced by laser application and to differentiate the effects of a potassium titanyl phosphate (KTP) laser and an intense pulsed light (IPL).

METHODS:
A randomized comparative study was performed on 10 adult volunteers with symmetrical rosacea treated by KTP laser or IPL. Skin temperature measurements were performed on inclusion, immediately after laser treatment and 3 min after thermal water application, using a high-resolution (0.08 degrees C) infrared thermal video camera.

RESULTS:
KTP laser treatment induced a significant rise in local skin temperature whereas no significant change was revealed by the IPL treatment. The infrared camera is a reliable and reproducible technique that allows a follow-up of skin temperature without skin contact.

CONCLUSION: Thermography using an infrared camera could potentially be applied in clinical pharmacology for inflammatory reactions or scarring processes.

Prevalence Of And Associated Factors For Dry Eye In A Spanish adult population

To estimate the prevalence of dry eye and to investigate its relationship with lifestyle and systemic factors in a general adult population in north-western Spain. METHODS: A dry eye questionnaire was administered and objective tests were performed in 654 individuals [mean age (Standard deviation): 63.6 (14.4) years, range: 40-96, 37.2% males]. Subjects were considered symptomatic when one or more of the symptoms of the questionnaire were present often or all the time. Schirmer test or= 3 and fluorescein staining >or= 1 were considered indicative of signs. Dry eye was defined as the simultaneous presence of symptoms and at least one sign. A design based analysis was performed and all calculations were weighted to give unbiased estimates. RESULTS: Dry eye prevalence was 11.0% (95%confidence interval [CI] 8.6-13.3). Dry eye was found to be more frequent in women (11.9%, 95%CI 8.8-15.1) than in men (9.0%, 95%CI 5.3-12.6), and was significantly associated with aging (p autoimmune diseas...

Before And After: A Gorgeous Zen Bathroom Remodel

Before And After: A Gorgeous Zen Bathroom Remodel " casacullen.com/2009/12/rwd-home-kitchen-redesign-before-and-after almost the same issue during my recent 1960s bath remodel, I house in prime vintage condition and wants to zen " We love when sustainability meets beauty in home renovations. And this Japanese-inspired bathroom remodel in by Weston Miles Architects is a prime example. These before photos show a pleasant enough bathroom with bright color and functional traditional cabinetry, though a small sink space, not-so eco-friendly materials, and dim lighting. This after photo shows an incredible remodel that makes use of traditional materials in a modern aesthetic. The focal point is this Japanese soaking tub that the client wanted, and the room grew around that. The room has been opened up for a step-in shower next to the tub, its warm lichen-green balanced against the natural wood of the tub and wood trim. This beautiful remodel exemplifie...
