ABSTRACT

ABSTRACT Introduction: It has been suggested that cystatin C levels are modified by obesity and inflammation. Furthermore, cystatin C has been associated with cardiovascular events and mortality outcomes. Aim: To study the association of cystatin C with the metabolic profile and cardiovascular disease of peritoneal dialysis patients. Methods: Data collected included clinical, laboratorial, and multifrequency bioimpedance assessment of 52 stable peritoneal dialysis patients. Minimal residual renal function was defined as > 2mL/min/1.73m2. Results: Serum cystatin C was not significantly associated with peritoneal or urinary cystatin C excretion. Negative correlation of cystatin C with normalized protein catabolic rate (rho -0.33, p = 0.02) and a trend towards positive correlation with relative body fat (rho 0.27, p = 0.05) were not independent from residual renal function. Cystatin C was not significantly associated with cardiovascular disease (p = 0.28), nor with glycated hemoglobin (p = 0.19) or c-reactive protein (p = 0.56). In the multivariate model, both age and diabetes were the strongest predictors of cardiovascular disease (odds ratio 1.09, p = 0.029 and odds ratio 29.95, p = 0.016, respectively), while relative body fat was negatively associated with cardiovascular disease (p = 0.038); neither cystatin C (p = 0.096) nor minimal residual renal function (p = 0.756) reached a significant association with cardiovascular disease. Conclusions: In this group of peritoneal dialysis patients, cystatin C did not correlate with the metabolic or inflammatory status, nor cardiovascular disease, after adjustment for residual renal function.


RESUMO Introdução: Tem sido sugerido que os níveis de cistatina C são modificados pela obesidade e inflamação. Além disso, a cistatina C tem sido associada a eventos cardiovasculares e desfechos de mortalidade. Objetivo: Estudar a associação da cistatina C com o perfil metabólico e doença cardiovascular de pacientes em diálise peritoneal. Métodos: Os dados coletados incluíram avaliação clínica, laboratorial e de bioimpedância múltipla de 52 pacientes estáveis em diálise peritoneal. A função renal residual mínima foi definida como > 2mL/min/1,73m2. Resultados: A cistatina C sérica não esteve significativamente associada à excreção peritoneal ou urinária. A correlação negativa da cistatina C com a taxa catabólica protéica normalizada (rho -0,33, p = 0,02) e uma tendência de correlação positiva com a gordura corporal relativa (rho 0,27, p = 0,05) não foram independentes da função renal residual. A cistatina C não se associou significativamente à doença cardiovascular (p = 0,28), nem com hemoglobina glicada (p = 0,19) ou proteína C reativa (p = 0,56). No modelo multivariado, idade e diabetes foram os mais fortes preditores de doença cardiovascular (razões de probabilidade 1,09, p = 0,029 e 29,95, p = 0,016, respectivamente) enquanto a gordura corporal relativa se associou negativamente à doença cardiovascular (p = 0,038). A cistatina C não se associou significativamente com doença cardiovascular (p = 0,096), tampouco a função residual mínima (p = 0,756). Conclusão: Neste grupo de pacientes em diálise peritoneal, a cistatina C não se correlacionou com o estado metabólico ou inflamatório, nem com doença cardiovascular, após ajuste para função renal residual.

ABSTRACT

Abstract Objective To evaluate the trends in definitive contraception in a ten-year interval comprising the years 2002 and 2012. Method Retrospective analysis of the tubal sterilization performed in our service in 2002 and2012,analyzingthedemographiccharacteristics,personalhistory,previouscontraceptive method, definite contraception technique, effectiveness and complications. Results Definitive contraception was performed in 112 women in 2002 (group 1) and in 60 women in 2012 (group 2). The groups were homogeneous regarding age, parity, educational level and personal history. The number of women older than 40 years choosing a definitive method was more frequent in group 1, 49.1% (n = 55); for group 2, the rate was 34.8% (n = 23) (p = 0.04). The time between the last delivery and the procedure was 11.6±6.2 and 7.9±6.4 years (p = 0.014) in 2002 against 2012 respectively. In 2002, all patients performed tubal ligation by laparoscopic inpatient regime. In 2012, the bilateral placement of the Essure (Bayer Corporation, Whippany, NJ, US) device was suggested to 56.1% (n = 37) of the patients, while laparoscopy was suggested to 43.9% (n = 29) of them. All women who underwent laparoscopic sterilization had the procedure successfully completed using silastic rings. The overall bilateral device placement rate for the Essure was 91.6%, with only one complication reported. All Essure procedures were performed in an outpatient setting; for the laparoscopy, this rate was 79% (n = 15). No intentional pregnancies occurred until this date. Conclusions There is a trend in the decrease in definitive contraception over the years in our institution, maybe as a result of the development of long-acting reversible contraceptives. The hysteroscopic procedure has become a frequent option, as it is performed in an office setting without anesthesia, being a well-tolerated, minimal invasive method.


Resumo Objetivo Avaliar as tendências da contracepção definitiva feminina num intervalo de 10 anos, 2002 e 2012. Métodos Análise retrospectiva das mulheres submetidas a esterilização em 2002 e 2012 no Serviço de Ginecologia de um hospital em Portugal, atendendo às caraterísticas demográficas, antecedentes pessoais, método contraceptivo prévio, técnica de contracepção efetuada, eficácia e complicações ocorridas. Resultados Foram submetidas a contracepção definitiva 112 mulheres em 2002 (grupo 1), e 66 em 2012 (grupo 2). Os grupos eram semelhantes na idade, paridade, nível educacional e antecedentes pessoais. O número de mulheres com mais de 40 anos que optou por um método definitivo foi superior no grupo 1, 49,1% (n = 55), versus 34,8% (n = 23) no grupo 2 (p = 0,04). O tempo decorrido entre o último parto e o procedimento foi de 11.6±6.2 anos e 7.9±6.4 anos (p = 0.014) em 2002 versus 2012, respetivamente. Em 2002, todas as mulheres foram submetidas a laqueação tubária em regime de internamento. Em 2012, a colocação bilateral do Essure (Bayer Corporation, Whippany, NJ, EUA) foi proposta para 56,1% (n = 37) das pacientes, enquanto a laparoscopia foi proposta para 43,9% (n = 29) delas. A laqueação por laparoscopia foi realizada com sucesso em todos os casos com anéis de silastic. A taxa de colocação bilateral do Essure foi de 91,6%, tendo sido registrada uma complicação. Todos os procedimentos com Essure foram realizados em regime de ambulatório, enquanto que tal se verificou em 79% (n = 15) daquelas pacientes submetidas a laparoscopia. Não ocorreram gravidezes não intencionais. Conclusão Parece haver uma tendência para a diminuição da esterilização como opção contraceptiva, provavelmente devido à disponibilidade de diversos métodos contraceptivos de longa duração aliada aos benefícios não contraceptivos. A opção pelo dispositivo Essure, mais recentemente, é justificada pela sua realização em contexto de consultório, sem anestesia, sendo um método minimamente invasivo e bem tolerado.

ABSTRACT

Lipschütz Ulcer, or ulcus vulvae acutum, is a rare and probably underdiagnosed entity that usually presents as an acute painful vulvar ulcer in young women. The etiology is unknown, although recent reports have associated it with the Epstein-Barr virus. The diagnosis is made by exclusion after ruling out sexually transmitted diseases, autoimmune causes, trauma, and other etiologies of genital ulcerations. We report a case of a young woman who developed flu-like symptoms and painful vulvar ulcers. Complementary examinations ruled out sexually transmitted diseases and the other usual causes of genital ulcers; lesions healed with no sequelae or recurrences. This case represents a rare important differential diagnosis of genital ulceration.

ABSTRACT

Lipschütz Ulcer, or ulcus vulvae acutum, is a rare and probably underdiagnosed entity that usually presents as an acute painful vulvar ulcer in young women. The etiology is unknown, although recent reports have associated it with the Epstein-Barr virus. The diagnosis is made by exclusion after ruling out sexually transmitted diseases, autoimmune causes, trauma, and other etiologies of genital ulcerations. We report a case of a young woman who developed flu-like symptoms and painful vulvar ulcers. Complementary examinations ruled out sexually transmitted diseases and the other usual causes of genital ulcers; lesions healed with no sequelae or recurrences. This case represents a rare important differential diagnosis of genital ulceration.


A Úlcera de Lipschütz, ou ulcus vulvae acutum, é uma entidade rara mas provavelmente subdiagnosticada, que se apresenta como úlcera vulvar aguda dolorosa numa mulher jovem. A etiologia é desconhecida embora relatos recentes a tenham associado à primo-infecção pelo vírus Epstein-Barr. O diagnóstico é estabelecido após exclusão de doenças sexualmente transmissíveis, causas autoimunes, traumáticas e outras etiologias de úlceras genitais. Relatamos o caso de uma jovem que desenvolveu quadro gripal e dolorosas úlceras genitais. Os exames complementares excluiram doenças sexualmente transmissíveis e as outras causas habituais de ulceração genital. As lesões cicatrizaram sem sequelas e sem recorrências. Este caso representa um diagnóstico diferencial importante e raro de ulceração genital.
