    Optimizing Outcomes in Free Flap Breast Reconstruction in the Community Hospital Setting: A Stepwise Approach to DIEP/SIEA Flap Procedures with Banking a Hemiabdominal Flap
    (2017) OKADA, Alberto; PEREIRA, Diego Daniel; MONTAG, Eduardo; PORTOCARRERO, Marcelo; FELICIO, Carlos; ARRUDA, Eduardo Gustavo; FONSECA, Alexandre; GEMPERLI, Rolf; MUNHOZ, Alexandre Mendonca
    Background Free flap breast reconstruction is a conventional procedure in many countries; however, microvascular compromise remains a devastating outcome. Given the morbidity of total necrosis, optimizing free flap salvage stands out as an important area for research, especially among surgeons to overcome the learning curve period and in resource constrained scenario such as community hospitals. To ensure free deep inferior epigastric perforator (DIEP)/superficial inferior epigastric artery (SIEA) flap breast reconstruction, the authors present a technique involving raising a hemiabdominal flap as a free flap, and banking the remaining flap to be utilized if needed in a subsequent procedure. Methods A retrospective review was performed on all free flap breast reconstructions. In this period, 84 patients (mean age: 50.18 years) were included. Results In this study, 65.5% patients underwent immediate reconstruction, and 51.2% received DIEP reconstruction; 9.52% patients were returned to the operating room, and salvage reconstruction using the banked flap was performed in all patients. No differences were observed regarding early complications and age, body mass index, American Society of Anesthesiologists status, diabetes, smoking history, chemotherapy, radiotherapy, and type of flap used ( p >0.05). Hypertension was significantly associated with early complications ( p <0.05). Donor-site complications were associated with RT ( p <0.05). Conclusion The banked flap is a reliable method for ensuring DIEP/SIEA flap survival and should be considered in higher risk reconstructions and community hospitals. We believe that the present technique can be a good addition to the arsenal of plastic surgeons dealing with free flap breast reconstructions in selected patients.

    Validation of Videoconference With Smartphones in Telemedicine Facial Trauma Care: Analysis of Concordance to On-Site Evaluation
    (2016) FONSECA, Alexandre Siqueira Franco; GOLDENBERG, Dov Charles; STOCCHERO, Guilherme Flosi; LUIZ, Arthur Vicentini Costa; GEMPERLI, Rolf
    Background The continental size of some countries and heterogeneous hospital network prevents patients who live in remote areas from getting adequate initial assessment of facial trauma. The authors present an alternative model for trauma assessment by videoconference via smartphones and analyze the concordance between telemedicine and face-to-face management. Methods Fifty patients with either a confirmed or suspected diagnosis of facial trauma were independently evaluated by 2 teams of physicians: Face-to-face and telemedicine-based. The face-to-face team attended patients at bedside (physical examination and computed tomography scan analysis). The telemedicine team consisted of a general surgery resident on duty in the emergency room and a plastic surgeon researcher remotely communicating via smartphones. Both teams answered a questionnaire, which contained data concerning patient's epidemiology, physical examination, computed tomography (CT) scan findings, and treatment option to be followed. Data were analyzed and compared regarding the similarity of answers. Results The sample studied was consistent with the literature, showing a predominance of young males. Traffic accidents and personal violence were the main causes of trauma. The concurrency of answers for physical examination findings was considered substantial ( = 0.720). For CT scan findings, it was almost perfect ( = 0.899); for defining the treatment option, it was almost perfect ( = 0.891). High concurrency of face CT scan findings was observed after we calculated the positive predictive value (89.9%), negative predictive value (99.3%), sensitivity (94.2%), specificity (98.8%), and accuracy (98.3%). Conclusions The proposed model to facial assessment trauma by videoconference via smartphones is feasible, showing high concordance level with face-to-face assessment.

    What a difference a clip makes! Analysis of boost volume definition in radiation therapy for conservative breast surgery
    (2018) FREITAS, Thiago Brasileiro de; LIMA, Kennya Medeiros Lopes de Barros; CARVALHO, Heloisa de Andrade; MARQUES, Patricia de Azevedo; MATTOS, Fabio Teixeira Belfort; FONSECA, Alexandre Siqueira Franco; MUNHOZ, Alexandre Mendonca; FILASSI, Jose Roberto; STUART, Silvia R.; MARTA, Gustavo Nader
    Purpose/objective(s): To evaluate the role of surgical clips placement in the definition of boost treatment volume. Materials/methods: Clinical Target Volumes (CTV) were defined as: CTV Breast, CTV Quadrant (based on physical exam and pre-surgical images), CTV Boost, defined by clip plus margin (1 cm for 2 or more clips and 2 cm for 1 clip only) plus radiological changes, CTV NT (normal tissue), defined by CTV Quadrant minus CTV Boost and CTV MISS (CTV that would be outside the treatment volume), defined by cry Boost minus CTV Quadrant. Results: A total of 247 patients were included. Upper lateral quadrant was the most common clinical location (47.3%). The median number of clips used was three. The mean volumes were: CTV Breast:982.52 cc, CTV Boost:36.59 cc, CTV Quadrant:285.07 cc, Cry NT:210.1 cc and CTV MISS:13.57 cc. Only 50.6% (125) of the patients presented the CTV Boost completely inside the Cry Quadrant and in 473% (117), partially inside. Among patients with any CFV MISS, 803% (98) had 10% or more of CTV Boost outside the treatment volume. Regarding CTV MISS, there were no statistically significant differences between the groups with 1 clip versus 2 or more clips, nor between patients with or without reconstructive surgery. In average, the CTV Boost was 87% smaller than the CFV Quadrant. The whole quadrant irradiation would lead to unnecessary irradiation of 26% of normal breast tissue. Conclusion: Surgical bed clipping is up most important in the definition of the boost volume irradiation to ensure precision minimizing geographical miss and optimizing surrounding normal tissue sparing.

    Avaliação do índice de infecção de implantes mamários utilizados na reconstrução de mama do Instituto do Câncer do Estado de São Paulo
    ABSTRACT Introduction: Placement of breast implants is the most commonly used form of breast reconstruction. Despite its advantages, infection of the implant, either in the tissue expander or mammary prosthesis, can be a significant problem, including the need to remove it. The objective of this work is to evaluate the infection rate of breast implants used for breast reconstruction in patients submitted to surgery at the Cancer Institute of the State of São Paulo (ICESP), as well as its correlation with clinical, oncological, and surgical factors. Patients and methods: This is a retrospective study on 120 patients submitted to breast reconstruction with breast implants at the ICESP from February 2009 to March 2010. Results: The infection rate (24.3%) was statistically related to immediate reconstruction (88.9%), diabetes mellitus (25%), body mass index >30 (52.8%), systemic arterial hypertension (52.8%), and skin injury due to mastectomy (27.8%). Of the infected implants, 44% were removed, most of which were expanders placed during immediate reconstruction. Conclusions: Breast reconstruction with implants is the safest and most effective form of treatment. However, consideration should be given to patients who are prone to the development of infection, in order to optimize its prevention and attempt to perform its treatment at an early stage.

    Influence of vitamin D status on hospital length of stay and prognosis in hospitalized patients with moderate to severe COVID-19: a multicenter prospective cohort study
    (2021) REIS, Bruna Z.; FERNANDES, Alan L.; SALES, Lucas P.; SANTOS, Mayara D.; SANTOS, Caroline C. Dos; PINTO, Ana J.; GOESSLER, Karla F.; FRANCO, Andre S.; DURAN, Camila S. C.; SILVA, Carla B. R.; MACEDO, Marina B.; DALMOLIN, Henrique H. H.; BAGGIO, Janaina; BALBI, Guilherme G. M.; ANTONANGELO, Leila; CAPARBO, Valeria F.; GUALANO, Bruno; MURAI, Igor H.; PEREIRA, Rosa M. R.
    Background: Vitamin D acts as a mediator in the immune system regulating antiviral mechanisms and inflammatory processes. Vitamin D insufficiency has been suggested as a potential risk factor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, although its impact on the prognosis of hospitalized patients with coronavirus disease 2019 (COVID-19) remains unclear. Objective: This multicenter prospective cohort study was designed to investigate whether serum 25-hydroxyvitamin D [25(OH)D] concentration is associated with hospital length of stay and prognosis in hospitalized patients with COVID-19. Methods: Patients with moderate to severe COVID-19 (n = 220) were recruited from 2 hospitals in Sao Paulo, Brazil. Serum 25(OH)D concentrations were categorized as follows: <10 ng/mL, 10 to <20 ng/mL, 20 to <30 ng/mL, and >= 30 ng/mL, and <10 ng/mL and >= 10 ng/mL. The primary outcome was hospital length of stay and the secondary outcomes were the rate of patients who required invasive mechanical ventilation and mortality. Results: There were no significant differences in hospital length of stay when the 4 25(OH)D categories were compared (P = 0.120). Patients exhibiting 25(OH)D<10 ng/mL showed a trend (P = 0.057) for longer hospital length of stay compared with those with 25(OH)D >= 10 ng/mL [9.0 d (95% CI: 6.4, 11.6 d) vs. 7.0 d (95% CI: 6.6, 7.4 d)]. The multivariable Cox proportional hazard models showed no significant associations between 25(OH)D and primary or secondary outcomes. Conclusions: Among hospitalized patients with moderate to severe COVID-19, those with severe 25(OH)D deficiency (<10 ng/mL) exhibited a trend for longer hospital length of stay compared with patients with higher 25(OH)D concentrations. This association was not significant in the multivariable Cox regression model. Prospective studies should test whether correcting severe 25(OH)D deficiency could improve the prognosis of patients with COVID-19.
