Background and objectivesNowadays, there are several noninvasive technologies being used for improving of body contouring. The objectives of this pilot study were to verify the effectiveness of the Heccus® device, emphasizing the synergism between nonfocused ultrasound plus Aussie current in the improvement of body contour, and to determine if the association of this therapy with whole-body vibration exercises can have additional positive effects in the results of the treatments.Subjects and methodsTwenty healthy women aged 20–40 years participated in the study. Ten patients received Combined Therapy treatment (G1) and the other 10 participants received Combined Therapy with additional vibratory platform treatment (G2). Anthropometric and standardized photography analysis, ultrasonography, cutometry and self-adminestered questionnaires of tolerance and satisfaction levels with the treatment were used.ResultsCompared with baseline values, reduction of fat thickness was observed by ultrasonography in the posterior thigh area in the G1 group (P<0.05) and in the buttocks (P<0.05) and the posterior thigh areas (P<0.05) in the G2. All the treated areas in both groups showed reduction in cellulite degree in the buttocks, G1 (P<0.05) and G2 (P<0.05), and in posterior thigh areas, G1 (P<0.05) and G2 (P<0.05). Optimal improvement of skin firmness (G1, P<0.0001; G2, P=0.0034) in the treated areas was observed in both groups.ConclusionWe conclude that the synergistic effects of the Combined Therapy (nonfocused ultrasound plus Aussie current) might be a good option with noninvasive body contouring treatment for improving the aspect of the cellulite, skin firmness and localized fat. If used in association with the whole-body vibratory platform, the results can be better, especially in the treatment of localized fat. Further studies with larger sample size should be performed to confirm these results.
This study brings important epidemiological data for the audit of mammographic screening, rare among us. Data have been analyzed as compared to what is recommended by the literature, the detection rate and the percentage of minimal and in situ carcinomas found being comparable to the established values, but with the VPP value lower than the ideal.
OBJECTIVE: Vacuum-assisted biopsy is the percutaneous technique of breast biopsy with the lowest underestimation rate. However, the cost of such procedure is high and currently there is a considerable interest in developing less expensive techniques. The present study was aimed at testing a less expensive device for vacuum-assisted biopsy of breast microcalcifications. MATERIALS AND METHODS: Thirty-five patients with clustered microcalcifications classified as BI-RADS® 4 or 5 were submitted to biopsy. Collected specimen appropriateness, difficulties in the reinsertion of the cannula and number of biopsy passes were evaluated. RESULTS: Successful specimens collection was achieved in all of the patients. Histo-radiological disagreement, difficulties in the cannula reinsertion or severe complications were not observed. CONCLUSION: The authors conclude that the method is effective in terms of specimens appropriateness and cost-benefit ratio as compared with of biopsy techniques for breast microcalcifications. Such findings are compatible with data reported in the literature.

O objetivo deste trabalho foi testar um dispositivo portátil de biópsia vácuo-assistida que apresenta custo menor. MATERIAIS E MÉTODOS: Foram biopsiadas 35 pacientes que apresentavam agrupamentos de microcalcificações BI-RADS® 4 ou 5. Foram testados a representatividade dos fragmentos colhidos, as dificuldades na reintrodução da cânula e o número de ciclos de colheita. RESULTADOS: Houve obtenção de calcificações representativas em todas as pacientes. Não houve discordância anatomorradiológica, dificuldade na reintrodução da cânula ou complicações graves. CONCLUSÃO: Os dados permitem concluir que o sistema apresenta boa eficácia na obtenção das amostras e com relação de custo-benefício favorável em relação a outros sistemas para a biópsia de microcalcificações, achados em concordância com outras publicações da literatura.

Avaliar um achado de ultrassonografia inédito (dilatação intrapapilar do duto lactífero) em pacientes portadoras de fluxo papilar patológico e em pacientes assintomáticas. Métodos: Foram estudadas 24 portadoras de fluxo papilar patológico e dilatação ductal intrapapilar e 1.255 pacientes assintomáticas (grupo controle). Resultados: Apenas uma paciente assintomática apresentou dilatação ductal intrapapilar. Entre as pacientes sintomáticas, 19 foram biopsiadas, 10 com abordagem exclusivamente percutânea, 6 com abordagem exclusivamente cirúrgica e 3 com abordagem inicialmente percutânea e depois cirúrgica. Houve um carcinoma invasor e dois carcinomas in situ (15,8% das pacientes biopsiadas). Em 11 pacientes foi encontrado papiloma, 3 deles com atipias. Em uma paciente a ultrassonografia identificou extensão intrapapilar de microcalcificações e em outra, um duto alterado diametralmente oposto ao duto com sinal do gatilho clínico. Nessas duas pacientes o exame mudou a estratégia de tratamento. Em duas pacientes, um achado extrapapilar só foi identificado após o encontro da dilatação ductal intrapapilar. Conclusão: A dilatação ductal intrapapilar é novo sinal ultrassonográfico que agrega sensibilidade à avaliação da paciente com fluxo papilar patológico, além de ajudar a encontrar a lesão e a orientar o tratamento. São necessárias pesquisas adicionais para determinar sua prevalência e seus valores preditivos positivo e negativo para câncer, atipias e papilomas.
