bookPart Reconstrução mamária(2019) OKADA, Alberto Yoshikazu; FONSECA, Alexandre Siqueira Franco; MUNHOZ, Alexandre Mendonça; ARRUDA, Eduardo Gustavo Pires de; MONTAG, Eduardo; GEMPERLI, Rolf- Serratus anterior muscle flap as a salvage procedure in exposed implant-based breast reconstruction(2019) MONTAG, Eduardo; OKADA, Alberto; ARRUDA, Eduardo G. P.; MUNHOZ, Alexandre M.; BUSNARDO, Fabio F.; GEMPERLI, RolfBACKGROUND: Implant-based breast reconstruction (IBR) is the most common approach to reconstruct mastectomy deffects. Infection following breast reconstruction can be devastating and lead to loss of the reconstruction due to the need of implant removal. The serratus anterior muscle flap is widely used during breast reconstruction to provide coverage of the implant/expander. METHODS: We present the application of the serratus anterior muscle flap to treat implant exposure after breast reconstruction. CASES PRESENTATION: Two patients who experienced implant exposure after breast reconstruction were successfully treated with partial capsulectomy, pocket irrigation and implant coverage with a serratus anterior muscle flap. RESULTS: No post operative complications have been observed while implant retention was achieved in both cases. CONCLUSIONS: The serratus anterior muscle flap is an option to treat implant exposure following breast reconstruction in selected cases. This flap could be used to prevent implant exposure in critical cases. (C) 2019 Published by Elsevier Ltd on behalf of IJS Publishing Group Ltd.
- Health effects of pollution on the residential population near a Brazilian airport: A perspective based on literature review(2019) FAJERSZTAJN, Lais; GUIMARAES, Mariana Tavares; DUIM, Etienne; SILVA, Tarsila Guimaraes Vieira da; OKAMURA, Mirna Namie; BRANDAO, Suzan Lucia Brancher; RIBEIRO, Ana Elisa; NAUD, Ludmila Macedo; O'SULLIVAN, Shane; SALDIVA, Paulo Hilario Nascimento; CARDOSO, Maria Regina AlvesIntroduction: Airport is an important source of air and noise pollution. Acute and chronic exposure to air pollution is harmful to human health with proven effects ranging from coryza, to eye irritation, and even to death. Both acute and chronic exposure to noise pollution are harmful to human health and have been related to cardiovascular diseases, hearing loss, cognitive disorders, sleep disorders, tinnitus and respiratory changes. It is plausible to consider that residing near airports increases the likelihood of developing health problems or exacerbate pre-existing conditions. In this study, we review the effects of pollution from airport activity on the health of the resident population located in the city of Guarulhos, near the International Airport of Sao Paulo. Methods: To perform this narrative review, a comprehensive search of published scientific literature on PubMed and a search in reference lists of selected papers were applied. Results: There is a widespread scarcity of international scientific literature relating to health effects of air and noise pollution on residents living near airports; none exists in Latin America. In general, airport activity is an important source of air and noise pollutants. Areas close to airports are usually more polluted. Conclusions: It is plausible to speculate that residing near airports (including Sao Paulo International Airport) increases the likelihood of developing health problems or exacerbating pre-existing conditions. Considering the volume and importance of air transport to society, it is incumbent to invest in mitigating alternatives to improve air quality and reduce noise around airports.
- Influência do posicionamento do retalho linfonodal vascularizado na resposta ao tratamento cirúrgico do linfedema secundário ao câncer de mama.(2019) MONTAG, Eduardo; OKADA, Alberto Yoshikazu; ARRUDA, Eduardo Gustavo Pires; FONSECA, Alexandre Siqueira; BROMLEY, Miluska; MUNHOZ, Alexandre Mendonça; BUSNARDO, Fábio Freitas; GEMPERLI, RolfABSTRACT Objective: to evaluate the initial therapeutic experience of transplantation of vascularized lymph nodes in patients with lymphedema of the upper limbs secondary to the treatment of breast cancer, and to verify if the positioning of the transplant influences the surgical result. Methods: we conducted a prospective, comparative test of two therapeutic modalities, with 24 patients with lymphedema of the upper limb after breast cancer treatment, classified as grades 2 and 3, according to the International Lymphedema Society. The two types of procedures performed were: 1) total breast reconstruction with - deep inferior epigastric perforator (DIEP) flap associated with lymph node flap, in patients with no previous breast reconstruction or loss of previous reconstruction (axillary positioning); 2) isolated inguinal lymph node flap performed in patients with completed breast reconstruction or without the desire to perform the breast reconstruction (wrist positioning). Results: the reduction percentage of the affected limb volume was 20.1% (p=0.0370). The number of infectious episodes (cellulites) also decreased significantly, from 41% in the preoperative period to 12.5% in the postoperative one (p=0.004). There were no differences between the proximal and distal groups. Conclusion: the transplantation of lymph nodes positively affected the postoperative evolution of patients with lymphedema secondary to breast cancer. We observed no differences in relation to flap positioning.
