SULT1A1 gene deletion in BRCA2-associated male breast cancer: a link between genes and environmental exposures?
2013
SULT1A1, a member of sulfotransferase superfamily, is a drug and hormone metabolizing enzyme involved in the metabolism of a variety of potential mammary carcinogens of endogenous and exogenous origin. Interestingly, the metabolic activity of SULT1A1 can be affected by varia- tions in gene copy number. Male Breast Cancer (MBC) is a rare disease and less investigated disease compared to female BC (FBC). As in FBC, the concurrent effects of genetic risk factors, particularly BRCA2 mutations, increased exposure to estrogens and environmental carcinogens play a relevant role in MBC. By quantitative real-time PCR with TaqMan probes, we investigated the presence of SULT1A1 gene copy number variat…
Surgical treatment of early breast cancer in day surgery.
2007
Quadrantectomy and associated sentinel lymph node biopsy (SLNB) is currently employed in most breast surgery centres as the gold standard in the treatment of early breast cancer. This approach has a modest morbidity and can usually be performed in a day-surgery regimen, leading to best acceptance by the patients. This reports outlines the experience of our Breast Unit with quadrantectomy and SLNB in day surgery for early breast cancer. One hundred patients presenting to our institution with primary invasive breast cancer measuring less than 3 cm and clinically negative axillary nodes underwent quadrantectomy and SLNB in day surgery. For 60 women with breast cancer the sentinel node was nega…

Développement précoce du comportement et des préférences alimentaires
2014
Manger est essentiel pour la survie, et nous naissons équipés pour absorber des nutriments à partir des apports alimentaires. Cependant, l'alimentation ne se résume pas à cet aspect. Quoi, comment, quand, combien manger sont autant de questions qui renvoient à d'autres aspects du comportement alimentaire, auxquelles il nous faut répondre quotidiennement. Ces autres aspects du comportement alimentaire sont appris, essentiellement durant les premières années de vie [1]. Ainsi, nous avons montré que les comportements alimentaires acquis à l'âge de 2 à 3 ans étaient prédictifs des mêmes comportements observés chez le jeune adulte [2,3]. Pour cette raison, il est fondamental de savoir quand et c…
Sytuacja uwięzionych kobiet w dwudziestoleciu międzywojennym
2015
The first legal document that introduced a distinction of treatment between imprisoned men and women was created during the interwar period. At that time, the need to differentiate the execution of the penalty methods between men and women was emphasized. This particular period initiated the beginning of formulating separate regulations related to the issue of imprisoned women. At first, they were treated as a homogeneous population. However, after some time, the need for alternative treatment of female prisoners, especially pregnant and breastfeeding, was noticed. Gradually, taking into account gender differences in the penitentiary interactions, slow evolution was taking place, especially…
Manejo del parto, puerperio y lactancia en mujeres positivas por SARS-CoV-2. Estudio multicéntrico en la Comunidad Valenciana
2021
Objetivo: Determinar las repercusiones maternas y perinatales de las gestantes con reacciónen cadena de la polimerasa positiva para SARS-CoV-2 durante el parto y el puerperio clínico.Método: Estudio observacional descriptivo, retrospectivo y multicéntrico realizado mediantela revisión de historias clínicas de las gestantes ingresadas por parto desde el 1 de marzo hastael 30 de junio de 2020.Resultados: Se analizaron 13 mujeres con reacción en cadena de la polimerasa positiva a SARS-CoV-2. La prevalencia de casos positivos fue del 0,48% sobre el total de partos atendidos en elperiodo de estudio. Ninguna de las madres desarrolló complicaciones derivadas de la infecciónpor COVID-19 ni necesitó…
Differenzierung zwischen prämaturer Thelarche und Pubertas praecox anhand klinischer, hormoneller und radiologischer Befunde
2008
In a retrospective study of 39 girls (aged 10 months to 7 10/12 years) with premature breast development criteria for distinguishing between premature thelarche and precocious puberty were analysed. Serum estradiol levels and bone age were determined and a test with luteinizing hormone-releasing hormone (LHRH) performed (inclusion criteria). On the basis of the LHRH test and bone age, premature thelarche was diagnosed in 29 patients and precocious puberty in ten: while those with premature thelarche had a follicle-stimulating hormone (FSH) pattern of rise, in those with precocious puberty the rise in gonadotropin was of the LH type. The LH/FSH ratio 30 min after stimulation was 1 (median 2.…
RASSF1A inhibits estrogen receptor alpha expression and estrogen-independent signalling: implications for breast cancer development
2012
The Ras association domain family 1 isoform A (RASSF1A) is a tumor suppressor whose inactivation is implicated in the development of many human cancers, including breast carcinomas. Little is known about the tumor-suppressive function of RASSF1A in breast tissue and whether its inactivation is mechanistically involved in the initiation and progression of breast tumors. Here, we show that RASSF1A inhibits breast cancer growth in vivo, and suppresses estrogen receptor (ERα) expression and function. Reconstitution of RASSF1A in MCF7 cells led to decreased ERα levels and reduced sensitivity to estrogen (E2). Concomitantly, we observed decreased expression of Id1 as well as the E2-responsive gen…
Prognostic and Functional Significant of Heat Shock Proteins (HSPs) in Breast Cancer Unveiled by Multi-Omics Approaches
2021
Simple Summary In this study, we investigated the expression pattern and prognostic significance of the heat shock proteins (HSPs) family members in breast cancer (BC) by using several bioinformatics tools and proteomics investigations. Our results demonstrated that, collectively, HSPs were deregulated in BC, acting as both oncogene and onco-suppressor genes. In particular, two different HSP-clusters were significantly associated with a poor or good prognosis. Interestingly, the HSPs deregulation impacted gene expression and miRNAs regulation that, in turn, affected important biological pathways involved in cell cycle, DNA replication, and receptors-mediated signaling. Finally, the proteomi…
Development of Histologically Verified Thyroid Diseases in Women Operated for Breast Cancer: A Review of the Literature and a Case Series
2022
Background: The possible relationships between breast and thyroid diseases have been reported in the literature. The purpose of our study was to evaluate the occurrence of histologically verified thyroid pathologies in women who were diagnosed with breast cancer and, after mastectomy/quadrantectomy complemented by oncological treatment, were thyroidectomized based on their periodic thyroid evaluation. Patients and Methods: Our series consist of 31 women with a mean age of 62.9 ± 10.9 years (range, 45–81) treated for breast cancer (18 right-sided, 11 left-sided, and 2 bilateral), of whom 29 were thyroidectomized, since two women who developed Graves’ disease refused thyroi…
