Sesquiterpene lactones are an important class of secondary metabolites frequently isolated from Vernonanthura genus that present a variety of biological properties, including antiproliferative activity. Due to the limitation of pharmacological studies on Vernonanthura nudiflora, the aim of this work was to investigate their antioxidant potential and antiproliferative activity against human tumor cells, as well as to isolate and identify the chemical constituents present in their aerial parts. The phytochemical investigation resulted in the isolation of the sesquiterpene lactones piptocarphins A, B, D, and a new hirsutinolide derivative, 8α-tigloyloxy-10α-hydroxy-hirsutinolide, besides triterpenes, glycosylated steroids, flavonoids, and one chlorogenic acid derivative. Also, other sesquiterpene lactones were identified by ultra-high performance liquid chromatography-high resolution tandem mass spectrometry (UHPLC-HRMS/MS) from dichloromethane fraction. This fraction showed activity against the tumor cells tested, mainly against leukemia, glioma, ovarian and kidney, with growth inhibitory activity (GI50) less than 0.80 µg mL-1. Piptocarphins A and B, in mixture, showed strong activity against all human cancer cell lines tested, with GI50 values ≤ 0.15 µg mL-1. Piptocarphin D was selective for glioma and resistant ovarian cell lines. The new hirsutinolide derivative showed potent activity against breast (GI50= 0.96 µg mL-1) and resistant ovarian (GI50 = 3.60 µg mL-1) cell lines.

RESUMO Há uma grande necessidade dos cirurgiões-dentistas estarem capacitados para proceder diante de pacientes com algum tipo de cuidado especial. Esse trabalho teve como objetivo realizar uma revisão de literatura sobre protocolos farmacológicos de como tratar pacientes portadores de necessidades especiais, dentro das diversas áreas que os cirurgiões-dentistas podem atuar. Métodos: Foi adotada como metodologia a revisão de artigos nos temas de Diabetes Mellitus, insuficiência renal crônica, hemofilia, pacientes cardiopatas, no período de 1980 a 2017 todos voltados para áreas da odontologia. Resultados: Foram selecionados 33 artigos da temática. Foram encontrados vários protocolos específicos para agir durante uma consulta de diversas doenças sistêmicas ou em casos especiais, afim de conseguir o sucesso durante o tratamento, evitar interações medicamentosas ou criar situações de emergências. Foi possível verificar, em alguns casos, um consenso entre as sequências ou o medicamento de primeira escolha para os pacientes portadores de necessidades especiais. Podem acontecer erros graves caso algum cirurgião-dentista não esteja capacitado para realizar a consulta nesses casos graves. A criação de um protocolo para esses pacientes nas diversas especialidades odontológicas diminuiria a quantidade de tratamentos com insucesso, assim aumentando a segurança e a eficácia dos tratamentos.

ABSTRACT There is a great need for dental surgeons to be trained to proceed with patients needing some kind of special care. This study aimed to perform a review of the literature on drug protocols concerning how to treat patients with special needs, within the different areas in which dentists may be engaged. The methodology employed was to review articles dealing with the subjects of diabetes mellitus, chronic renal failure, hemophilia, cardiac patients, which were focused on areas of dentistry. A total of 33 articles were selected. Several specific protocols were found on how to act during a consultation of several systemic diseases or in special cases, in order to achieve success during treatment, to avoid drug interactions or to create emergency situations. It was possible, in some cases, to find a consensus between the sequences or the drug of first choice for patients. Serious errors can occur if a dentist is not capable in serious cases. The creation of a protocol for these patients in the different dental specialties would reduce the number of failed treatments, thus increasing the safety and effectiveness of the treatments.

ABSTRACT Introduction: The nipple-areola complex (NAC) plays an important role both in breastfeeding and sexual lives of the patients. Because of this, we must mention possible complications of reduction mammoplasty, such change or even loss of sensitivity of the NAC. Method: This was a prospective, randomized, controlled, double-blind study to evaluate the relationship between the sensitivity of the NAC after reduction mammoplasty with dermal release and the resected volume of breast tissue. This study was conducted between August 2013 and August 2015 at the Hospital das Clínicas of the Federal University of Pernambuco (HC-UFPE), in Recife City, Brazil. Results: The study involved 39 patients. The mean age and body mass index (BMI) of the patients were 31.7 years and 25.5 kg/m2, respectively. None of the patients was a smoker. The complication rate was 41%, including 7 cases of non-aesthetic scars, 6 cases of hematoma (bruises), and 4 cases of dehiscence. No patient had pain or NAC necrosis, and all the patients expressed being satisfied with the final surgical result. No statistically significant differences were found between the patients of the experimental and control groups, both in the group with resection of up to 300 g and those with resection >300 g. Conclusions: The maneuver of dermic release did not result in any differences in the sensitivity of the NAC, regardless of the quantity of resected breast tissue.

RESUMO Introdução: O complexo areolopapilar (CAP) desempenha grande importância tanto na amamentação quanto na vida sexual das pacientes, consequentemente, devemos ressaltar que uma complicação potencial da mamoplastia redutora é a alteração ou até a perda da sensibilidade do CAP. Método: Estudo prospectivo, randomizado, controlado e duplo-cego para avaliar a relação entre a sensibilidade do complexo areolopapilar após mamoplastia redutora com liberação dérmica e o volume ressecado de tecido mamário. O estudo ocorreu no período de agosto de 2013 a agosto de 2015, no Hospital das Clínicas da Universidade Federal de Pernambuco (HC-UFPE). Resultados: O estudo totalizou 39 pacientes. A média de idade da amostra foi de 31,7 anos, índice de massa corporal (IMC) médio de kg/m2 e nenhuma das pacientes era tabagista. A taxa de comorbidade foi de 5,1% da amostra. O índice de complicações foi de 41%, composto de 7 casos de cicatriz inestética, 6 de hematoma e 4 de deiscência. Não houve caso de sofrimento ou necrose do CAP e todas as pacientes se mostraram satisfeitas com o resultado cirúrgico final. Não houve diferenças estatisticamente significantes em nenhuma das ocasiões entre os pacientes do grupo experimento e controle, tanto no grupo de ressecção de até 300 gramas quanto acima de 300gramas. Conclusões: A manobra de liberação dérmica não provocou diferença na sensibilidade do complexo areolopapilar, independentemente da quantidade de tecido mamário ressecado.

ABSTRACT Objective The objective of this study was to correlate the values of abdominal circumference (AC) and body mass index (BMI) with the levels of total testosterone (TT), free testosterone (FT) and sexual hormone binding globulin (SHBG). We aimed to analyze the association between the anthropometric values and variations in the hormonal levels. Subjects and methods A transversal prospective study was conducted. A total of 159 patients were included in the study. Results BMI was inversely correlated with TT and SHBG (p = 0.02 and p = 0.006, respectively). AC was also inversely correlated withTT and SHBG (p = 0.006 and p < 0.0001, respectively). However, BMI did not correlate signicantly with these hormonal levels after adjusting for age. Conclusion This finding led to the conclusion that AC had a stronger inverse correlation than BMI with TT and SHBG. Our data suggested that AC alone can be used as an anthropometric parameter to help simplify the identification of men with low serum TT levels.
