Coexistence of benign phyllodes tumor and invasive ductal carcinoma in distinct breasts: case report

This report describes a rare case of coexistence of benign phyllodes tumor, which measured 9 cm in the right breast, and invasive ductal carcinoma of 6 cm in the left breast, synchronous and independent, in a 66-year-old patient. The patient underwent a bilateral mastectomy due to the size of both lesions. Such situations are rare and usually refer to the occurrence of ductal or lobular carcinoma in situ when associated with malignant phyllodes tumors, and more often in ipsilateral breast or intra-lesional.

Material de cama: qualidade, quantidade e efeito sobre o desempenho de frangos de corte

An experiment was conducted to evaluate performance, mortality and incidence of lesions on the breasts, hooks and foot pads of broilers raised on wood-scrap litter, rice hulls, Brachiaria hey (Brachiaria decumbens), Napier hay (Pennisetum purpureum) and Coast-cross hay (Cynodon dactylon). A randomized experimental design with five litters, two sexes, four replications and fifty birds per box was used. A standard litter height of 5 cm of wood-scraps and a weight of 20 250 g were adopted as criteria for use of other materials in the boxes. The amount of excreta deposited was 1697 g per raised bird (34,00 % of feed consumption). The incidence of lesions was evaluated in five birds per box after 35, 42 and 49 days and after slaughter. The criteria for scoring lesions were: 0 = without lesion; 1 = inflammation; 2 = mild ulceration; 3 = severe ulceration. At the end of experimental period (49 days) no differences were observed For weight, weight gain, feed consumption, feed/gain ratio and mortality among treatments. The lesions of the hocks and foot pads of the birds, raised on either Coast-cross hay and Napier hay, were more severe than those on wood-scraps and Brachiaria hay. Males showed better performance than females, but their hock lesions were more severe, independent of the litter used. Based on the performance and lesions scores, it was concluded that Braquiaria hay could be used as litter in replace wood-scraps and rice bulls.

Effects of soy isoflavones on mammographic density and breast parenchyma in postmenopausal women: A randomized, double-blind, placebo-controlled clinical trial

OBJECTIVE: This study aims to evaluate the effects of soy isoflavones on breast tissue in postmenopausal women. METHODS: In this randomized, double-blind, placebo-controlled study, 80 women (aged ≥45 y and with amenorrhea >12 mo) with vasomotor symptoms were randomized to receive either 250 mg of standardized soy extract corresponding to isoflavone 100 mg/day (n = 40) or placebo (n = 40) for 10 months. Breasts were evaluated through mammographic density and breast parenchyma using ultrasound (US) at baseline and 10-month follow-up. Independent t test, analysis of variance, Mann-Whitney U test, and χ2 trend test were used in statistical analysis. RESULTS: Baseline clinical characteristics showed no significant differences between the isoflavone group and the placebo group, with mean (SD) age of 55.1 (6.0) and 56.2 (7.7) years, mean (SD) menopause duration of 6.6 (4.8) and 7.1 (4.2) years, and mean (SD) body mass index of 29.7 (5.0) and 28.5 (4.9) kg/m2, respectively (P > 0.05). The study was completed by 32 women on isoflavone and 34 women on placebo. The groups did not differ in mammographic density or breast parenchyma by US (P > 0.05). Within each group, the baseline and final moments did not differ in mammography or US parameters significantly (P > 0.05). CONCLUSIONS: The use of soy isoflavone extract for 10 months does not affect breast density, as assessed by mammography and US, in postmenopausal women. © 2013 by The North American Menopause Society.

Median ages at stages of sexual maturity and excess weight in school children

Background: We aimed to estimate the median ages at specific stages of sexual maturity stratified by excess weight in boys and girls.Materials and method: This was a cross-sectional study made in 2007 in Florianopolis, Brazil, with 2,339 schoolchildren between 8 to 14 years of age (1,107 boys) selected at random in two steps (by region and type of school). The schoolchildren were divided into: i) those with excess weight and ii) those without excess weight, according to the WHO 2007 cut-off points for gender and age. Sexual maturity was self-evaluated by the subjects according to the Tanner sexual development stages, and utilizing median ages for the genitalia, breasts, and pubic hair stages.Results: In the boys with excess weight, precocity was observed in the stages 4 for genitals and pubic hair and 2 for pubic hair, with the values for excess and normal weight. The median ages at the beginning of puberty (stage 2-sexual development) for boys and girls in Florianopolis were 10.8 and 10.3 years, respectively.Conclusion: Excess weight is associated with lower median ages in the sexual maturity stages in boys and girls and that it should be taken into account when evaluating sexual maturity in children and adolescents.

Ultrasonografia Doppler na reprodução de pequenos animais

The Doppler ultrasound allows the assessment of blood flow and the differentiate vessels according to each spectral pattern, location and organ that irrigate, helping the examinations and disease diagnosis. The main methods used are Pulsed Doppler, Color Doppler and Power Doppler. In Brazil veterinary medicine, it shows progress since 1990, but its use is limited by the equipment high cost, the need for operator experience and patient cooperation. There are studies in obstetrics and reproduction of dogs and cats, such as evaluation of the testicular vasculature, including the use of contrast material, and attempts to evaluate prostate in healthy dogs or pathological conditions (cancer and testicular torsion , orchitis and benign prostatic hyperplasia; estrous cycle monitoring, evaluation of irrigation in follicles and corpus luteum, uterus and breasts (mammary tumors) in bitches; monitoring pregnancy from the assessment of maternal, fetal and placental hemodynamics, both in dogs as in cats, and aspirations for early detection of pregnancy in dogs. However, new studies are still required, given the lack of these species, especially cats

Stunning method in broiler chickens meat processing

Quality is a variable concept, which involves many factors, depending on the consumer market. In meat production, the concern with environmental aspects, animal welfare and the health and safety of workers is increasing. This work studied the effect of controlled atmosphere stunning of broilers on meat features and biochemical parameters for stress. Cobb broilers were stunned by electrical stunning and by controlled atmosphere with 70% CO2 and 70% CO2 + 30% Argon. After stunning, serum levels of glucose, lactate and corticosterone were compared with those of broilers at rest, immediately before transportation and slaughter and after 12 h of feed withdrawal (control group). At slaughter, blood volume drained during bleeding was not different for the stunning methods tested, ranging from 3.3 to 3.4% birds weight. This finding was important to demonstrate that gas stunning was not responsible for the animals′ death. Final pH in breast (6.1 to 6.2) and thigh (6.3 to 6.5) also did not vary among the different stunning methods (P > 0.05). Lightness (L = 60.55) and redness (a = +8.94) values found for breasts from electrical stunning showed that they were darker and redder (P < 0.05), probably due to changes in blood pressure. Glucose and corticosterone levels were not different between gas stunned birds (302.45 to 315.7 mg/dl and 55.71 to 72.49 ng/ml respectively) and birds at rest (305.95 mg/dl and 50.65 ng/ml) (P > 0.05). These stress indicators were higher (337.65 mg/dl for glucose and 104.13 ng/ml for costicosterone) when electrical stunning was used (P < 0.05). Lactate concentrations were lower (5.4 mmol/l) for birds at rest (P < 0.05) but not different for all stunning methods tested (7.3 to 8.1 mmol/l; P > 0.05). These results show that serum glucose may be used as a stress indicator in birds, with the advantage of being a quick and cheap biochemical test. Gas stunning favored birds′ management during slaughter and so reduced workers′ effort and injury hazard and the amount of feces and dust in the room. To make this method available for a large scale process, adjustments in equipments will be necessary to avoid delays in the processing line.
