Effects of skin care habits on the development of rosacea: A multi-center retrospective case-control survey in Chinese population.

BACKGROUND: Certain cosmetic habits may trigger or aggravate rosacea, while there is little published epidemiologic evidence to support this point. PURPOSE: To examine if daily skin care habits have an effect on the development of rosacea in Chinese population. METHODS: A multi-center retrospective case-control survey of 1,245 rosacea cases and 1,538 skin-healthy controls was conducted in China. Participants completed the questionnaire comprised of demographic characteristics, socioeconomic data and daily skin care habits. Data were collected retrospectively and analyzed using the chi-square test and t-test. Multivariate logistic regression analyses were used to predict rosacea. RESULTS: The multivariate logistic regression analysis highlighted some results: Dry, oily or mixed skin (OR = 6.3-6.9, P< .001), the usage of foaming cleanser (OR = 1.45, 95%CI 1.115-1.886, P = .01), make up more than 6 times a week (OR = 2.839, 95%CI 1.962-4.108, P< .001), using facial mask more than 4 times a week (OR = 2.56-3.069, P< .001), facial treatments at beauty salon more than once a week (OR = 4.946, 95%CI 2.005-12.198, P = .0018) and using beauty salon products (OR = 2.334, 95%CI 1.435-3.976, P = .0018) are positively correlated with the development of rosacea. Using of moisturizing products (OR = 0.602, 95%CI 0.386-0.983, P = .035) and sunscreen cream (OR = 0.303-0.507, P< .001 or P = .0167 for different frequency) presented significantly negative correlations with rosacea. Frequency of cleansing showed a nonlinear association with rosacea: using facial cleansers 1~3 times per week (OR = 0.647, 95%CI 0.429-0.975, P = .038) showed beneficial effects while using facial cleanser excessively (twice or more daily) (OR = 2.131, 95%CI 1.394-3.256, P< .001) positively correlated to rosacea strongly. CONCLUSIONS: Excessive use of facial cleanser (twice or more a day) and facial mask (more than 4 times a week), frequent makeup (more than 6 times a week), regular skin care in beauty salon (more than once a week), and using beauty salon products were closely correlated to the development of rosacea in Chinese population.

Endoscopic decompression of the optic canal for traumatic optic neuropathy / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>Traumatic optic neuropathy (TON) is a serious complication of head trauma with the incidence rate of 0.5%-5%. The aim of this study was to investigate the therapeutic efficacy of endoscopic decompression of the optic canal for optic nerve injuries.</p><p><b>METHODS</b>In this study, 11 patients treated in our hospital from January 2009 to January 2015 with the visual loss resulting from TON were retrospectively reviewed for preoperative vision, visual evoked potential (VEP) scan, surgical approach, postoperative visual acuity, complications, and follow-up results.</p><p><b>RESULTS</b>All these patients received endoscopic decompression of the optic canal. At the 3-month follow- up, the visual acuity improvement rate of the 11 patients was 45.5%. The vision acuity of 2 cases improved from hand movement to 0.08 and 0.3 after operation. Another patient's vision acuity returned to 0.05 compared to light sensation preoperatively. Two cases had finger counting before surgery but they had a vision acuity of 0.4 and light sensation respectively after surgery. However, the other 6 cases' vision did not improve after surgery.</p><p><b>CONCLUSION</b>Endoscopic decompression of the optic canal is an effective way to cure TON. VEP could be used as an important reference for preoperative and prognosis evaluation. Operative time after trauma is only a relative condition that may affect the therapeutic effect of optic canal decompression. Poor results of this procedure may be related to the severity of the optic nerve injury.</p>
