Because of their widespread use, fragrances are among the most common causes of contact allergic dermatitis, second only to nickel. During a five-year period 3,065 patients with contact dermatitis were patch tested using a specific mix of fragrances. 509 (16.6%) patients were allergic to the fragrance mix, while 258 (8.4%) patients exhibited an allergic reaction to Myroxylon pereirae (balsam of Peru). Between those 509 patients, 157 were patch tested with eight individual substances contained in the fragrance mix: cinnamal, cinnamyl alcohol, eugenol, isoeugenol, geraniol, hydroxycitronellal, alpha-amyl cinnamal and Evernia prunastri (oak moss). The most frequent allergens were isoeugenol 57.9% (91/157), eugenol 55.4% (87/157), cinnamyl alcohol 34.4% (54/157) and Evernia prunastri (oak moss) 24.2% (38/157). There were 62 patients (39.5%) who exhibited an allergic reaction to both the fragrance mix and Myroxylon pereirae (balsam of Peru). The results prove the importance of avoiding allergens in daily life, especially in industrial and cosmetic products. In order to prevent ACD, better cooperation between industry and dermatologists is needed.

Collagen metabolism is altered in the pelvic organ tissues of women with genital prolapse. The aim of this study was to compare collagen metabolism by measuring matrix metalloproteinase – 1 (MMP – 1) expression in uterosacral ligament tissues of postmenopausal women with and without genital prolapse. Uterosacral ligament tissues were obtained at the time of abdominal or vaginal surgery from twenty-four patients with pelvic organ prolapse (POP) and 21 women who underwent gynecologic surgery for benign indications. The tissue samples were analyzed by immunohistochemistry. There were no differences in age, BMI and parity between two groups. The patients with genital prolapse demonstrated significantly higher occurences of MMP – 1 expression compared to controls. These findings indicate that increased MMP – 1 expression in uterosacral ligaments is associated with genital prolapse. Our data are consistent with the theory that increased collagen breakdown may play an important role in the onset and development of pelvic organ prolapse (POP).

The aim of this study was to investigate the prevalence of pelvic organ prolapse in urban and rural women and to identify possible related factors. They were 1749 participants; one thousand four hundred seventeen (81%) urban women and 332 rural residents (19%). The urban and rural women were congruently regarding to age, parity, using oral contraceptives and postmenopausal status. The urban women were more often obese (p<0.01), estrogen replacement users (p< 0.001), smokers (p<0.001), with mild (p<0.001) and high (p<0.001) education, and they were often divorced (p<0.05) than rural women. Rural women were more often alcohol consumers (p<0.001), with low level of education (p<0.001) and more often married (p<0.05) than rural examinees. There were no association between the presence of prolapse and: weight, menopausal status, oral contraceptives and estrogen replacement using, smoking, alcohol consuming and marital status. There were not observed differences in prevalence of prior hysterectomy, urinary incontinence, uroinfectio, sexual and bowel dysfunction between both groups. The prevalence of cystocele, rectocele and uterine prolapse were similar among urban and rural participants. In conclusion, a more complete picture of factors associated with genital prolapse would include in investigation, such as molecular and genetic ones.
