Secretory IgA in human serum.

Secretory component (SC) was detected by the radioactive single radial diffusion technique in nearly all sera examined. The SC was shown to be associated with polymeric serum IgA. The mean level of secretory IgA (SIgA) in normal sera from India, Africa and Europe was about 0.03 to 0.04 mg/ml. The mean level was elevated in patients with a variety of disorders involving secretory surfaces (e.g., acute bacterial enterocolitis or respiratory tract carcinoma), but also in disorders with no known involvement of secretory surfaces. The highest levels were seen in lactating women, with a mean level five times higher than that in the general population. SIgA was also found at lower levels in cord serum, serum from breast-fed newborns and serum from children 3 to 10 years old.

Triade de la femme sportive [Female athlete triad]

The practitioner, as well as specialist such as gynecologist and endocrinologist, may face in their office women with eating disorders, abnormalities of menstrual cycles and low bone mass, which may be the first hints of the female athlete triad. In these situations, the practitioner may search other findings of these triad by looking at some particular physical findings and by using appropriate questionnaire. In some advanced forms of this triad specific abnormalities of eating disorders (anorexia and boulimia) may be present as well as amenorrhea and osteoporosis, which may disturb the well-being and cause health damages of women practising sport either as amateur or in a elite setting. An appropriate handling of such disorders has to be proposed to these women.

A new procedure to assess the energy requirements of lactation in Gambian women.

The combined 24-h energy expenditure (24-h EE) of mother and child was measured with a respiratory chamber (indirect calorimeter) in a group of 16 lactating Gambian women and was compared with that of a control group of 16 nonpregnant, nonlactating (NPNL) Gambian women. Breast-milk production (738 +/- 47 g/d: mean +/- SE) was adequate to allow a normal rate of growth of their 2-mo-old babies (28.0 +/- 2.4 g/d). The combined 24-h EE (mother and child) was higher (8381 +/- 180 kJ/d. P less than 0.001) than that of NPNL women (6092 +/- 121 kJ/d). Two-thirds of this differences could be attributed to the child's EE and one-third to a greater spontaneous physical activity of lactating women. The energy retained by the child for growth in conjunction with the calorimetric measurements allowed the calculation of the extra energy requirements for lactation, which were found to be 2100 kJ/d. These results confirm the values of the current dietary recommendations for lactation, based on the energy cost of milk production.

Pregnancy-induced chromatin remodeling in the breast of postmenopausal women.

Early pregnancy and multiparity are known to reduce the risk of women to develop breast cancer at menopause. Based on the knowledge that the differentiation of the breast induced by the hormones of pregnancy plays a major role in this protection, this work was performed with the purpose of identifying what differentiation-associated molecular changes persist in the breast until menopause. Core needle biopsies (CNB) obtained from the breast of 42 nulliparous (NP) and 71 parous (P) postmenopausal women were analyzed in morphology, immunocytochemistry and gene expression. Whereas in the NP breast, nuclei of epithelial cells were large and euchromatic, in the P breast they were small and hyperchromatic, showing strong methylation of histone 3 at lysine 9 and 27. Transcriptomic analysis performed using Affymetrix HG_U133 oligonucleotide arrays revealed that in CNB of the P breast, there were 267 upregulated probesets that comprised genes controlling chromatin organization, transcription regulation, splicing machinery, mRNA processing and noncoding elements including XIST. We concluded that the differentiation process induced by pregnancy is centered in chromatin remodeling and in the mRNA processing reactome, both of which emerge as important regulatory pathways. These are indicative of a safeguard step that maintains the fidelity of the transcription process, becoming the ultimate mechanism mediating the protection of the breast conferred by full-term pregnancy.

Les métastases orbitaires [Orbital metastasis]

PURPOSE: The purpose of this paper is to present our data and to provide some conclusions about the attitude that has to be chosen when metastasis of the orbit is suspected. PATIENTS AND METHODS: Between 1965 and 1994, 571 patients with non-traumatic orbital diseases were controlled in the department of ophthalmology of Lausanne. Thirty-four cases of metastasis of the orbit were selected, that is 24 females and 10 males, aged from 1 to 81 years. Tumors of the breast are the most frequent origin of this metastasis, followed by cutaneous melanomas and pulmonary tumors. Orbital metastasis was the first sign of a malignant process in 7 patients. The histologic diagnosis was confirmed in 15 patients. The type of treatment is presented herein and the follow-up of more than half of the cases is given. RESULTS AND CONCLUSION: Orbital metastasis can develop after a long time in patients who were previously treated for malignant tumors. In several cases, orbital metastasis was the first sign of a malignant process which starts to become general. This diagnosis has to be taken into account when a patient was treated earlier for a malignant tumor, and it is reasonable to propose a biopsy or an excision biopsy in every orbital pathology which was not confirmed by clinical or paraclinical investigations.

Differential migration of in vivo primed B and T lymphocytes to lymphoid and non-lymphoid organs.

Our study describes tissue-specific migration of T and B cells during a localized anti-viral immune response. After mouse mammary tumor virus (MMTV) injection, B lymphocytes of the draining lymph node become infected and present a retroviral superantigen to CD4(+) T lymphocytes. Infected B cells receive superantigen-mediated help in a fashion comparable to classical immune responses. To investigate the fate of T and B lymphocytes that had interacted via cognate help in the same peripheral lymph node microenvironment we adoptively transferred them into naive recipients. Here we show that MMTV-infected B cells and superantigen-stimulated T cells were programmed to migrate to distinct sites of the body. Plasmablasts but not T cells migrated to the mammary gland and activated alpha4beta1 integrins were found to have a crucial role in the migration to the mammary gland. In contrast, T cells had a much higher affinity for secondary lymphoid organs and large intestine. This demonstrates that upon antigen-driven B and T lymphocyte interaction in the local draining lymph node a subset-specific homing program for B and T lymphocytes is induced.

Contrast enhanced breast ultrasound to differentiate papillomas from intraductal secretion : initial experience : P22

Purpose: To describe low mechanical index grey scale contrast enhanced breast ultrasound in patients with intraductal echogenic material in the differentiation of papillomas from intraductal secretions. Methods and materials: In five patients with echographically detected ductal dilatation containing echogenic material low mechanical index grey scale contrast enhanced ultrasonography was performed. No patient had nipple discharge. The examination was performed with a 9 MHz linear transducer after injection of 4 ml of Sonovue. It was assessed if contrast enhancement was present or not. The results were correlated with histologic results after surgical resection or percutaneous biopsy when performed. Results: In 3 patients contrast enhancement was observed. These patients were operated and the papillomas confirmed by histology. In two patients no contrast enhancement was observed. In one of these two patients percutaneous biopsy was performed without evidence of a papillary lesion. The second patient presented with multiple dilated ducts containing echogenic material. No biopsy was performed but breast MRI showed no intraductal enhancement supporting the non papillary nature of the intraductal material. Conclusion: This pilot study shows that contrast enhanced ultrasound is able to detect the vascularisation of papillomas and that it may differentiate intraductal papillomas from secretions.

Development of model observers applied to 3D breast tomosynthesis microcalcifications and masses

The development of model observers for mimicking human detection strategies has followed from symmetric signals in simple noise to increasingly complex backgrounds. In this study we implement different model observers for the complex task of detecting a signal in a 3D image stack. The backgrounds come from real breast tomosynthesis acquisitions and the signals were simulated and reconstructed within the volume. Two different tasks relevant to the early detection of breast cancer were considered: detecting an 8 mm mass and detecting a cluster of microcalcifications. The model observers were calculated using a channelized Hotelling observer (CHO) with dense difference-of-Gaussian channels, and a modified (Partial prewhitening [PPW]) observer which was adapted to realistic signals which are not circularly symmetric. The sustained temporal sensitivity function was used to filter the images before applying the spatial templates. For a frame rate of five frames per second, the only CHO that we calculated performed worse than the humans in a 4-AFC experiment. The other observers were variations of PPW and outperformed human observers in every single case. This initial frame rate was a rather low speed and the temporal filtering did not affect the results compared to a data set with no human temporal effects taken into account. We subsequently investigated two higher speeds at 5, 15 and 30 frames per second. We observed that for large masses, the two types of model observers investigated outperformed the human observers and would be suitable with the appropriate addition of internal noise. However, for microcalcifications both only the PPW observer consistently outperformed the humans. The study demonstrated the possibility of using a model observer which takes into account the temporal effects of scrolling through an image stack while being able to effectively detect a range of mass sizes and distributions.

Sentimentos e experiências na vida das mulheres com câncer de mama

Identificar os sentimentos e as experiências relacionados ao câncer de mama torna-se importante para que as pessoas de seu convívio social compreendam essa etapa da vida da mulher. Uma revisão da literatura foi realizada buscando identificar quais são os pensamentos e os sentimentos mais comuns experimentados pelas mulheres depois do diagnóstico de câncer de mama. Foi realizada por meio de busca bibliográfica no LILACS e MEDLINE, e as palavras-chave utilizadas foram: breast, câncer, feeling, female, representações, sentimentos. Conteúdos do câncer foram abordados, como o significado da doença e suas implicações para a vida emocional e social da mulher. Concluiu-se que as experiências relacionadas ao câncer de mama têm um âmbito muito individual, tendo representações diferenciadas para cada mulher.

Breast sarcomas: current and future perspectives.

Breast sarcomas are rare neoplasms of the breast that need to be clearly distinguished from the very common breast carcinomas and treated in a multidisciplinary manner modelled after treatment paradigms in other sarcoma locations. An increasing need to differentiate sarcoma sub-types based on molecular characteristics that will also be depicted in differential treatment sensitivities and development of specifically targeted therapies are equally valid in sarcomas in general and in breast sarcomas in particular. Of special interest in breast are sarcomas developing after breast irradiation for a previous breast carcinoma, a scenario that is increasingly common, given the increasing trends of breast conservation in the surgical treatment of breast carcinoma that necessitates the adjuvant use of radiotherapy.

Cancer mortality in Europe, 2000-2004, and an overview of trends since 1975.

BACKGROUND: To update the pattern of cancer mortality in Europe. Materials and methods: We analysed cancer mortality in 34 European countries during 2000-2004, with an overview of trends in 1975-2004 using data from the World Health Organization. RESULTS: From 1990-1994 to 2000-2004, overall cancer mortality in the European Union declined from 185.2 to 168.0/100 000 (world standard, -9%) in men and from 104.8 to 96.9 (-8%) in women, with larger falls in middle age. Total cancer mortality trends were favourable, though to a variable degree, in all major European countries, including Russia, but not in Romania. The major determinants of these favourable trends were the decline of lung (-16%) and other tobacco-related cancers in men, together with the persistent falls in gastric cancer, and the recent appreciable falls in colorectal cancer. In women, relevant contributions came from the persistent decline in cervical cancer and the recent falls in breast cancer mortality, particularly in northern and western Europe. Favourable trends were also observed for testicular cancer, Hodgkin lymphomas, leukaemias, and other neoplasms amenable to treatment, though the reductions were still appreciably smaller in eastern Europe. CONCLUSION: This updated analysis of cancer mortality in Europe showed a persistent favourable trend over the last years.

Advanced nursing role to improve care among breast cancer patients

Background: Breast cancer is a devastating disease for women as it impacts on their intimate, familial, social life. We study the specificities of breast cancer nurse interventions related to demands of support, information and coordination. Material and Methods: More than 300 patients are treated every year in our institution. From 2006 January to 2008 December, the specialist nurse has reported demands of patients and professionals: 1. Patients' needs related to support, information and coordination of care were collected from consultations with her and from their phone calls on using working days help line 2. Demands of breast cancer specialists and general practitioners related to information and coordination for specific patients were collected from their phone calls. Results: The specialist nurse received 679 phone calls respectively 71.5% from patients and 28.5% from professionals. Data are presented in the following table. Table 1: Evolution of number of patients and professionals demands Patients consultations Patients calls Professionals calls 2006 93 45 32 2007 210 200 40 2008 245 240 122 - Seventy percent (70%) of women asked for information about exams and treatments by phone and in nurse consultation. - Forty percent (40%) of women asked for support after announce of diagnosis. The specialist nurse proposed consultations, 2 to 4 consultations were necessary for women to express emotional distress or psychosocial problem. With this specialised nursing support less than 15% of patients were referred to the psycho-oncologist setting. - Forty percent (40%) of professionals asked support for patients and 60% for information and coordination of care. Conclusion: The interventions of the specialist nurse have improved coordination and quality of care. The increase of professionals' demands showed that it was necessary that a nurse assures continuity of information between hospital and extrahospital structures. The breast cancer nurse empowers patients and helps them to get well by providing support to fulfil specific needs.
