The aim of this study was to evaluate the effectiveness of an exercise program for the recuperation of the range of motion (ROM) of the shoulder. This is a quasi-experimental study developed at the Mastology Outpatient Clinic of the Federal University of São Paulo - Brazil, from August 2006 to June 2008, with 64 breast cancer patients undergoing surgery. The intervention consisted of: preoperative evaluation of the ROM, verbal and written guidance, demonstration and implementation of the exercises and revaluation at the outpatient follow-up appointments until the 105th postoperative day (PO). From the 7th PO a significant increase was observed in the ROM, which continued until the 105th PO. The minimum time for recovery was 105 days for the women undergoing mastectomy, and 75 days for those undergoing quadrantectomy. There was satisfactory adherence of 78.6% of the women. The domicile program was effective for the recovery of ROM in the study population, benefiting women who can not attend a presential program.

Os nódulos mamários benignos são responsáveis por até 80% das massas palpáveis. Seu diagnóstico diferencial é amplo, envolvendo os cistos mamários, os fibroadenomas, os tumores filóides, os papilomas, os lipomas, os hamartomas e os adenomas, entre outros. O fibroadenoma é a neoplasia mamária mais comum em pacientes menores de 35 anos e os cistos são mais freqüentes na perimenopausa. O diagnóstico diferencial entre nódulos sólidos ou císticos poderá ser feito por meio da punção aspirativa com agulha fina ou pela ultra-sonografia, sendo terapêutica para os últimos. Neste artigo serão revisados os aspectos diagnósticos diferenciais entre estes tumores e as novas abordagens terapêuticas.

Radio-guided occult lesion localization is a valid technique for the diagnosis of suspicious non-palpable lesions. Here we determine the feasibility of pre-operative localization of occult suspect non-palpable breast lesions using radio-guided occult lesion localization, as well as for identifying the sentinel lymph node. This is a descriptive study of data collected retrospectively. Pre-operative mapping of 34 breast lesions in 25 patients suspected of being malignant was performed using conventional imaging methods with a magnetic resonance imaging-guided radiopharmaceutical injection. The mean time required to perform the localization was 25 minutes. After resection of the lesions using a gamma probe, malignancy was confirmed in fifteen patients (60.0%), with nine invasive ductal carcinomas, two invasive lobular carcinomas, and four in situ ductal carcinomas The resection was confirmed by the complete removal of the radioactive material. The pathologic results and images were concordant in all but two cases, which were submitted for new magnetic resonance imaging examinations and surgery that confirmed the malignancies. Of the 15 patients with confirmed malignancies, 10 had sentinel lymph node resection. Of these, eight were negative for metastases, one had micro-metastases and one had confirmed metastases. Three patients had full axillary node dissection, with metastases found in only one. No side effects were observed with magnetic resonance-guided radiopharmaceutical injection. The sentinel node occult lesion localization technique is a simple, reproducible and effective alternative approach to occult lesions compared to other methods, such as mammotomy and the hook-wire localization technique, for mapping suspect breast lesions and identifying lymph node metastasis.

CONTEXT AND OBJECTIVE: Dendritic cell maturation is considered essential for starting an immune response. The CD83 antigen is an important marker of dendritic cell maturation. The objectives here were to analyze CD83 antigen expression in human breast fibroadenoma and breast tissue adjacent to the lesion and to identify clinical factors that might influence this expression. DESIGN AND SETTING: This was a retrospective study at a public university hospital, in which 29 histopathological samples of breast fibroadenoma and adjacent breast tissue, from 28 women of reproductive age, were analyzed. METHODS: The immunohistochemistry method was used to analyze the cell expression of the antigen. The antigen expression in the cells was evaluated by means of random manual counting using an optical microscope. RESULTS: Positive expression of the CD83 antigen in the epithelial cells of the fibroadenoma (365.52; standard deviation ± 133.13) in relation to the adjacent breast tissue cells (189.59; standard deviation ± 140.75) was statistically larger (P < 0.001). Several clinical features were analyzed, but only parity was shown to influence CD83 antigen expression in the adjacent breast tissue, such that positive expression was more evident in nulliparous women (P = 0.042). CONCLUSIONS: The expression of the CD83 antigen in the fibroadenoma was positive and greater than in the adjacent breast tissue. Positive expression of the antigen in the adjacent breast tissue was influenced by parity, and was significantly more evident in nulliparous women.

Male breast cancer is rare, and because of its low incidence, treatment strategies often rely on data extrapolated from female breast cancer. Cryoablation
