- Reconstruction of acquired ischiatic and perineal defects: an anatomical and clinical comparison between gluteal thigh and inferior gluteal perforator flaps(2018) MONTAG, Eduardo; UEDA, Thiago; OKADA, Alberto; ONISHI, Bruno; GEMPERLI, RolfBackground Flap coverage is the gold standard in treating pressure sores, and due to the high recurrence rate, the possibility of multiple surgical procedures should be considered during flap selection. The gluteal thigh (GT) flap has become a workhorse for ischiatic pressure sore treatment at our hospital. Follow-up revealed a group of patients presenting recurrence of the pressure sore that needed a second flap. The inferior gluteal artery perforator (IGAP) flap was chosen in this series. The positive experience with both flaps raised the question of which flap should be the first option for the treatment of ischiatic and perineal pressure sores. Methods IGAP and GT flaps were dissected in 21 fresh human cadavers to allow comparison of anatomical features. In a series of 60 patients, the authors used both the gluteal thigh and the IGAP flap to cover 76 ischiatic and perineal ulcers. Results The IGAP flap was found to be wider and thicker than the gluteal thigh, but presented a shorter pedicle. All flaps healed uneventfully. Recurrent ulcers were treated successfully with both flaps. Conclusions Both flaps are suitable for coverage ischiatic and perineal sores. Due to its anatomical features, the IGAP flap should be considered the first choice of treatment for ischiatic ulcers. The gluteal thigh flap should be used in the recurrent sores.
- 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.
