The good, the bad and the ugly: estudo sobre pequenas e médias empresas familiares brasileiras a partir da teoria da ação de Pierre Bourdieu

According to Bourdieu (1994), there are social camps where the economic logic works upside down. Therefore, the expression ¿family business¿ is paradoxical because inside it resides two distinct and, sometimes, antagonistic logics: the business logic, whose goal is the profit, and the family logic, which aims at the common welfare. That is why one must consider the symbolical exchanges influences on the social relations more than in any other kind of company. Based on these concepts, this research presents an overview of the small and medium brazilian family business universe.

Adjuvant therapy with GnRH agonists/tamoxifen in breast cancer should be a good council for patients with hormone receptor-positive tumours and wish to preserve fertility

Infertility represents one of the main long-term consequences of the chemotherapy used for the adjuvant treatment of breast cancer. Approximately 60-65% of breast cancers express the nuclear hormone receptor in premenopausal women. Adjuvant endocrine therapy is an integral component of care for patients with hormone receptor-positive (HR+) tumours. The GnRH agonist (GnRHa) alone or in combination with tamoxifen produces results at least similar to those obtained with the different chemotherapy protocols in patients with HR+ breast cancer with respect to recurrence-free survival and overall survival. It is time to indicate adjuvant therapy with GnRHa associated with tamoxifen for patients with breast cancer (HR+ tumours) if they want to preserve their reproductive function. The evaluation of ovarian reserve tests: follicle stimulating hormone (FSH), anti-Mullerian hormone (AMH), inhibin B, antral follicle count (AFC) and ovarian volume 6 months, and 1 year after the end of therapy with GnRHa/tamoxifen must be realised. The recurrence-free survival and overall survival should be analysed. The major implication of this hypothesis will be to avoid adjuvant chemotherapy for patients with breast cancer (HR+ tumours) that request fertility preservation. It is expected that ovarian function should not be altered in almost all cases and subsequent pregnancy a real possibility. (C) 2012 Elsevier Ltd. All rights reserved.

Age-related histopathological lesions in the Mongolian gerbil ventral prostate as a good model for studies of spontaneous hormone-related disorders

The Meriones unguiculatus (Mongolian) gerbil has demonstrated significant prostatic responses to hormonal treatments, and to drugs against human prostatic hyperplasia Spontaneous neoplasia develops in the older animals. Thirty gerbils (age 18 months) were divided into non-affected and prostatic lesion bearers and the prostate lesions were evaluated morphologically, immunohistochemically and quantitatively. The most frequent changes were in epithelial sites and, namely prostatic intraepithelial neoplasias, microinvasive carcinomas and adenocarcinomas. In the stromal compartment, cellular hyperplasia, when verified, was always associated with the sites of anomalous epithelium. Additionally, larger deposition of collagen fibrils, generating stromal fibrosis, was found in all the old gerbils analysed. The quantitative analysis showed that prostatic tissue proportions differed in altered areas, being specific for each lesion type. Isolated nuclear and nucleolar parameters were not effective in diagnosing the malign potential of lesions. However, the cellular proliferation and death indexes indicated larger cellular turnover in invasive lesions such as carcinomas. With these analyses, it could be verified that old gerbils present high propensity to develop spontaneous prostate changes and this may aid in a better understanding of the biological behaviour of human prostate cancer.

AN EXTREMELY LARGE, CAULIFLOWER-TYPE, CUTANEOUS METASTASIS OF OVARIAN-CANCER ASSOCIATED WITH GOOD PROGNOSIS

We report an unusual case of a 37-year-old woman who presented in 1980 with a serous papillary cystadenocarcinoma of the ovary. The patient refused any treatment and the patient was lost to follow-up for 6 years. After this period of time she returned with an extremely large, cutaneous, cauliflower-type of metastasis located in the lower abdominal wall and measuring 20 x 20 cm. She received two courses of chemotherapy treatment consisting of intraperitoneal cisplatin (100 mg/m2) and intravenous epirubicin (50 mg/m2) every 3 weeks. After the second course of chemotherapy she received cobalt radiotherapy (5000 cGy). Subsequently, she received four more courses of chemotherapy with dramatic remission of the cutaneous metastasis. Shortly after chemotherapy, the patient underwent a laparotomy consisting of the resection of the abdominal wall including the cutaneous metastasis completed by total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy. The patient is well after the surgery and without any evidence of residual disease after 6 years of follow up. This description illustrates a rare example of ovarian cancer with skin metastases and favorable outcome. (C) 1994 Academic Press, Inc.

ARE CORPORAL ALLOMETRIC MEASUREMENTS GOOD PREDICTORS of PALATABILITY IN NEOTROPICAL BUTTERFLIES (LEPIDOPTERA)?

Since palatable butterflies are more dependent on evasive flight to escape from predators, they should be more restricted in their flight-related morphology than unpalatable ones. We compared: the ratios between the (1) length of head plus thorax and the length of abdomen (A/B), (2) length of the tip of the head to wing base and the length of the wing base to end of the abdomen (C/D), (3) the variances of A/B and C/D, (4) the proportion between the thoracic and the body weight, and (5) the flight speed between palatable and unpalatable butterflies. A/B and thoracic/body weight were higher for palatable species, indicating higher body symmetry and muscular mass. However, flight speed did not differ. Unexpectedly, the variance of A/B was higher for palatable species while that of C/D did not differ. Therefore, corporal allometric measurements of Neotropical butterflies are good predictors of palatability, though not of flight speed.

Adjuvant therapy with GnRH agonists/tamoxifen in breast cancer should be a good council for patients with hormone receptor-positive tumours and wish to preserve fertility

Infertility represents one of the main long-term consequences of combination chemotherapy used for the treatment of breast cancer. Approximately 60%-65% of breast cancers express the nuclear hormone receptor in premenopausal women. Adjuvant endocrine therapy is an integral component of care for patients with hormone receptor-positive (HR+) tumours. The GnRH agonist (GnRHa) alone or in combination with tamoxifen produces results at least similar to those obtained with the different chemotherapy protocols in patients with HR+ tumors with respect to recurrence-free survival and overall survival, Presentation of the hypothesis: It is time to indicate adjuvant therapy with GnRHa associated with tamoxifen for patients with breast cancer (HR+ tumours) if they want to preserve their reproductive function. Testing the hypothesis: Assessment of ovarian reserve tests: follicle stimulating hormone (FSH), anti-Mullerian hormone (AMH), inhibin B, antral follicle count (AFC) and ovarian volume 6 months, and 1 year after the end of therapy with GnRHa/tamoxifen.
