“…The BI-RADS classification has represented the first attempt to standardize mammographic findings in descriptive terms, constituting an important ancillary tool in both in cases of suspect malignancy and definition of conduct to be adopted (5,(7)(8)(9) . Studies correlating mammographic and histological findings in non-palpable breast lesions employing the BI-RADS classification have found PPV for breast cancer between 12.3% and 47.8% (4,7,8,10-12) .…”

Correlação radiológica e histológica de lesões mamárias não-palpáveis em pacientes submetidas a marcação pré-cirúrgica, utilizando-se o sistema BI-RADS

OBJETIVO: Avaliar as categorias 3, 4 e 5 da classificação BI-RADS (Breast Imaging Reporting and Data System) como fator preditivo para malignidade, correlacionando os achados mamográficos e histológicos em lesões não-palpáveis da mama. MATERIAIS E MÉTODOS: Estudo analítico descritivo de 169 mulheres submetidas a biópsia cirúrgica, após localização estereotáxica de lesões mamárias não-palpáveis. As mamografias dessas pacientes foram classificadas de acordo com a quarta edição do BI-RADS, avaliando-se as categorias 3, 4 (A, B e C) e 5. Correlacionaram-se os achados mamográficos com os exames histológicos das lesões, avaliando-se o valor preditivo positivo em cada categoria. RESULTADOS: No total de 169 casos, foram diagnosticados 42 casos de câncer (24,8%). Destes, houve apenas um caso na categoria 3, 19 casos na categoria 4 e 22 casos na categoria 5. Os valores preditivos positivos para as categorias 3, 4A, 4B, 4C e 5 foram, respectivamente, de 3,4%, 10,3%, 11,3%, 36% e 91,7%. As microcalcificações foram o achado mais freqüente relacionado à doença maligna, ocorrendo em 61,5% do total. CONCLUSÃO: Este estudo demonstrou que a classificação BI-RADS permite predizer com segurança que há alta suspeição de malignidade para achados classificados na categoria 5 e diminuta chance para os achados da categoria 3. Quanto à categoria 4, foi constatada elevação progressiva dos valores preditivos positivos nas subcategorias A, B e C, mostrando que esta subdivisão contribui de forma mais detalhada e precisa na indicação de lesões suspeitas para malignidade.

Climacteric in untreated isolated growth hormone deficiency

et al. 2008

Objective-To study the time, intensity of symptoms, hormonal profile, and related morbidity of climacteric in women with untreated isolated growth hormone (GH) deficiency (IGHD).Design-Women belonging to a large Brazilian kindred with IGHD due to a homozygous mutation in the GH-releasing hormone receptor gene were studied. None of them had ever received GH replacement therapy. A two-step protocol was performed. In the first case-control experiment, aimed to determine the age at climacteric, we compared eight women with IGHD and 32 normal women between 37 and 55 years of age. In the second cross-sectional experiment, aimed to determine the severity of climacteric symptoms, seven women with IGHD (aged 47-65 y) were compared with 13 controls (aged 44-65 y). The Kupperman Index scores, serum follicle-stimulating hormone, luteinizing hormone, prolactin, and estradiol levels were determined, and pelvic and mammary ultrasonography, mammography, and colpocytology were performed.Results-The number of women with follicle-stimulating hormone above 20 mIU/mL was higher in women with IGHD than controls. Kupperman's Index was not different between the two groups. Menarche had been delayed and parity was lower in women with IGHD. Hormonal profile was similar, but prolactin was lower in women with IGHD. Uterine volume was smaller in women with IGHD, and endometrial thickness and ovarian volume were similar in the two groups. No difference in breast images or in colpocytology was observed between the two groups.Conclusions-Menarche was delayed and the beginning of climacteric is anticipated in untreated lifetime IGHD, but menopausal symptoms and hormonal profile resemble the normal climacteric. KeywordsClimacteric; Growth hormone deficiency; Growth hormone; Releasing hormone receptor; Gene mutation Climacteric usually occurs between 40 and 55 years of age and is characterized by the exhaustion of the ovarian follicles with the reduction of serum inhibin and estradiol and an increase in serum follicle-stimulating hormone (FSH), with menstrual cycle abnormalities usually appearing when FSH is above 20 mIU/mL and menopause occuring when it is above 40 mIU/mL. Climacteric causes several genital, urinary, nervous, metabolic, and cardiovascular alterations. The relationships between growth hormone (GH) and menopause are not fully understood. In rodents, GH deficiency (GHD) reduces litter size and the number of primordial follicles, suggesting that GH is required for normal female reproductive function female. 2 In humans, the accomplishment of puberty requires a critical weight, 3 and individuals with untreated GHD reach this weight at a later age, and they usually therefore present with delayed puberty. GH has important modulatory effects on gonadotropin-dependent and -independent functions of the ovary, affecting gametogenesis and steroidogenesis. 4 Accordingly, GH therapy has been used in assisted reproduction with different outcomes. 5,6 However, the effects of lifetime untreated GHD on climacteric are not known.In Itabaia...

“…However, mammography still remains as the most relevant imaging technique for breasts. In order to standardize mammographic findings reporting, the BI-RADS classification was developed, subdividing imaging findings into five classes as follows: negative, benign, probably benign, suspicious and highly suspicious of malignancy (6) .…”

Hemangioma de mama é um tumor benigno raro que apresenta pouca ou nenhuma captação de 18F-flúor-2-deoxi-Dglicose (FDG) na tomografia por emissão de pósitrons (PET). Relatamos um nódulo mamário compatível, patologicamente, com hemangioma, em uma mulher cuja PET scan demonstrou captação elevada de FDG (simulando tumor maligno). Também fizemos breve revisão das causas que levam a resultados falso-positivos e falso-negativos pela PET.
