- Diabetic Mastopathy: a Case ReportPublication . Francisco, C; Júlio, C; Fontes, AL; Silveira Reis, I; Fernandes, R; Valadares, S; Sereno, PDiabetic mastopathy (DMP) is an uncommon collection of clinical, radiological, and histological features, classically described in premenopausal women with long-term insulin-dependent diabetes mellitus. This entity can mimic breast carcinoma, but, in the appropriate clinical and imaging setting, the diagnosis can be made by core biopsy, avoiding unnecessary surgeries. We report the case of a 34-year-old female, with a 12-year history of type 1 diabetes, who presented with bilateral breast lumps. Mammography, ultrasonography, and magnetic resonance imaging could not exclude the suspicion of malignancy, and a core biopsy was performed showing the typical histologic features of DMP. The literature is briefly reviewed.
- Fluoroscopia na Remoção de Implantes Profundos de EtonogestrelPublication . Coelho, A; Isidro Amaral, P; Silveira Reis, I; Machado, AIA fluoroscopia é uma técnica de imagem que permite obter imagens em tempo real com recurso a raio-X. Apesar de descrita na literatura a utilização da fluoroscopia em diversas áreas da medicina, em determinadas especialidades esta técnica permanece pouco difundida. Neste sentido, os dois casos clínicos descritos demonstram o sucesso na extração de implantes radiopacos de etonogestrel profundos através do uso da fluoroscopia, revelando-se uma técnica promissora alternativa ou complementar às técnicas convencionais utilizadas, o raio-X e a ecografia. A fluoroscopia tem um perfil de segurança elevado com uma fácil curva de aprendizagem, pelo que o seu domínio pelas especialidades envolvidas na remoção de implantes poderá contribuir para a resolução de casos mais complexos de extração de implantes subcutâneos.
- Implante Contraceptivo Não Palpável - Estratégias para a sua Localização e RemoçãoPublication . Isidro Amaral, P; Correia, L; Silveira Reis, I; Machado, AIOverview and Aims: The contraceptive implant is frequently used to provide contraceptive protection over three years. The implant is inserted into the subcutaneous tissue of the upper arm, and should be palpable and easily removed. We evaluated the best imaging strategy for non-palpable implant (Implanon®) localization and removal. Study Design: Retrospective study. Population: A total of 11 women referred to a tertiary care hospital, between October 2009 and January 2012, for localization and removal of their non-palpable implants. Methods: Different localization methods (ultrasound and magnetic resonance imaging) were evaluated for non-palpable rod. Results: Seven of the nonpalpable implants were inserted in a health care center, three in a district hospital and one in a private clinic. In three women, the reasons for requesting removal were the end of the implant validity, two wanted to become pregnant, two had weight gain, one had weight loss, one referred irregular bleeding, one had two implants and one did a hysterectomy. In 81.8% (9) of the women, the implants were identified and localized by ultrasound, and successfully removed. In two patients the implant was not found and therefore not removed. Conclusions: In our study, high resolution ultrasound proved to be a sensitive method in implants localization, being the primary choice for determining the location of nonpalpable implants.
- Use of Etonogestrel Implant Beyond Approved Duration – A Case ReportPublication . Castro Carvalho, C; Silveira Reis, I; Machado, AIThe contraceptive implant is the most effective method of reversible contraception. Observational and trial data indicate that this method remains effective beyond the initially approved duration of use. We report a case of etonogestrel serum levels above the supposed threshold value for ovulation suppression nine years after implant insertion.
