RESUMO
BACKGROUND: Rosacea is a common, chronic disorder that can present with a variety of cutaneous or ocular manifestations. Skin involvement primarily affects the central face, with findings such as persistent centrofacial redness, papules, pustules, flushing, telangiectasia, and phymatous skin changes. The pathways that lead to the development of rosacea are not well understood. The relationship of pyoderma faciale (also known as rosacea fulminans) to rosacea also is uncertain. We aimed to write this article with the aim of showing how a pregnant patient who has been aggravated by the degree of lesions on the face during the first trimester of pregnancy is treated and to show what is in the literature in this issue. CASE REPORT: A 22-year-old woman complained of painful erythema, papules and pustules on the face. She had fever and malaise during the sixth week of her first pregnancy and a history of the mild eruption and seborrhea before her pregnancy with flaring over the preceding 4 weeks. Dermatologic examination revealed red erythema of all involved facial areas; the lesions consisted of papules, pustules and nodules. The case was diagnosed as rosacea fulminans (pyoderma faciale) by these findings. In the literature, there are some effective therapeutic options such as retinoids, tetracyclines, antiandrogenic contraceptives, and dapsone and these were not used because they are contraindicated in pregnancy. Amoxicillin-clavulanic acid 1 gr/day, wet compresses, and a fusidic acid cream were started. After the activity of the disease had been suppressed for 10 days, antibiotic was stopped, and the other treatment options were applied topically for the next month. One month after cessation of treatment, the lesions had disappeared with only mild erythema remaining. There was minimally flushing on the face and no telangiectasia. CONCLUSION: In conclusion, there is no substantial evidence as to the mechanism by which pregnancy may trigger this conditioner whether the gender of the fetus influences the development of rosacea fulminans, but is generally accepted that hormonal changes in pregnancy play an important role. The pathogenesis of rosacea fulminans remains uncertain, but it is obvious that the further basic and clinical research is required to optimise the management of this rare facial dermatosis.
RESUMO
BACKGROUND/AIM: Narrowband UVB (Nb UVB) treatment is commonly used for the management of psoriasis and atopic dermatitis, and is less often used for vitiligo in children. The aim of this study was to evaluate the efficacy and short-term safety of Nb UVB phototherapy in children diagnosed with vitiligo retrospectively. MATERIALS AND METHODS: A total of 26 patients younger than 18 years with the diagnosis of vitiligo and managed with Nb UVB phototherapy as documented in archive records were evaluated. Clinical response was assessed according to repigmentation of the lesions: good response when there was more than 75% repigmentation, moderate response when there was 25%-74% repigmentation, poor response when repigmentation was less than 24%, and unresponsive when there was no pigmentation and new lesions occurred. RESULTS: A total of 26 patients received Nb UVB treatment; 14 were girls and 12 were boys. The age at onset of the disease varied between 2 and 18 years, with a mean age of onset of 10.07 ± 4.53 years. Repigmentation rate of >75% was detected in 45.4% of cases. CONCLUSION: Nb UVB phototherapy seems to be a well-tolerated effective and safe treatment option in children, especially those unresponsive to topical treatment and those with widespread lesions. However, long-term risks such as photocarcinogenesis and photoaging should kept in mind.
