Resumo Objetivos: investigar a frequência e analisar os fatores de risco para soroconversão entre nascidos vivos de mães soropositivas ao HIV. Métodos: foi realizado estudo de coorte, com crianças residentes na Região Sul de Santa Catarina. Foram usados dados secundários referentes a ficha de notificação e acompanhamento de criança exposta ao HIV e revisão do prontuário das mães das crianças infectadas. Participaram do estudo todos os nascidos vivos no período de 2005 a 2015 expostos ao HIV por transmissão vertical atendidos no serviço municipal de saúde. Resultados: houve 104 exposições ao HIV, sendo que em três casos se confirmou soroconversão e dois foram a óbito por Aids.O aleitamento materno (RP=32,7; IC95%=10,7-99,5); p=0,002) e o não uso de antirretroviral durante a gestação (RP=18,2; IC95%=2,0-163,0); p=0,008) foram fatores de risco para a soroconversão. Conclusões: a soroconversão em neonatos na Região Sul de Santa Catarina foi similar à média nacional. Houve associação com não utilização de terapia antirretroviral durante a gestação e aleitamento materno.

Abstract Objectives: to analyze both frequency and risk factors for seroconversion among newborns of HIV-positive mothers to HIV. Methods: a cohort study was conducted with children residing in Southern Region of Santa Catarina. Secondary data from the notification files and medical records of newborn's mothers of infected infants were used. The participants were all the newborns from 2005 to 2015 that were exposed to HIV through vertical transmission and attended a municipal health care center. Results: there were 104 cases of infant exposure to HIV. Seroconversion was confirmed in three cases, two of them died of AIDS during the study period. Breastfeeding (PR= 32.7; CI95%= 10.7-99.5; p= 0.002) and non-use of antiretroviral drugs during pregnancy (PR=18.2; CI95%= 2.0-163.0; p= 0.008) were risk factors for HIV seroconversion. Conclusions: seroconversion rates among neonates in Southern Region of Santa Catarina were similar to the national average. Seroconversion was associated with non-use of antiretroviral therapy during pregnancy and breastfeeding.

Abstract: BACKGROUND: Internal malignancies such as breast cancer, as well as their treatment can often result in skin changes. OBJECTIVE: To assess the prevalence of dermatological complaints in patients who are undergoing oncological treatment for breast cancer in a hospital in Tubarão, Santa Catarina, Brazil. METHODS: Observational, cross-sectional study, from October 2015 to February 2016 in which 152 patients with the diagnosis of breast cancer, undergoing treatment with chemotherapy, radiotherapy, hormone therapy and/or surgery, were interviewed and completed a research protocol developed by the author. RESULTS: The treatment of breast cancer was associated with dermatological complaints in 94.1% of the interviewed, being with hair loss the most frequent, present in 79.6% of the sample, followed by nail changes (56%). Patients with lighter skin phototypes (I, II and III) had a lower risk (p=0.045) of developing skin changes when compared to darker phototypes. Radiation therapy (p=0.011) and oncological surgery (pFisher=0.004) were statistically significant when related to skin changes. STUDY LIMITATIONS: Inherent to the design of the study, as well as recall bias. CONCLUSIONS: It was found that most patients diagnosed with breast cancer showed dermatologic manifestations during the proposed cancer treatment. Patients undergoing radiotherapy and surgery showed skin changes with greater statistical significance.
