    (2014) PINTO, Nathali Cordeiro; BAPTISTA, Ivany Machado de Carvalho; PEREIRA, Mara Helena Corso; SERRAO JUNIOR, Nelson Francisco; POMERANTZEFF, Pablo M. A.; CHAVANTES, Maria Cristina
    Background and Objective: Complications following cardiovascular surgery incision are common in mediastinitis and wound dehiscence form, a 47% mortality rate remaining. Low Level Laser Therapy (LLLT) has been employed mainly to its effectiveness analgesic and anti-inflammatory actions, aiding the tissue repair process. The aim of this study was to evaluate infrared LLLT onto surgical incision in patients submitted to cardiovascular surgery. Materials and Methods: 40 patients were divided in two groups: Placebo Group (G1) - conventional therapy + ""Laser pointer"" and Laser Group (G2) - conventional therapy + Infrared Laser irradiation on surgical incision. Diode Laser was employed, C. W. mode, around the surgical wound bed, on immediate Post Operative (PO), 1st PO and 3rd PO with the following parameters: wavelength (lambda): 830nm, P=35mW, E=0,75J. Results: G2 didn't present any complication and 5% of patients in G1 developed incision dehiscence and infection. On 7thPO, still a large amount of G1 patients showed pain and unquestionable inflammatory signs surrounding the surgical wound, when compared to G2. Besides, hospital stay in Laser Group was 2 times shorter than in Placebo Group (p-value=0.001). Conclusion: Infrared Laser denoted to be safe and exceptionally valuable tools in preventing morbidities on post cardiovascular surgeries.

    Post-operative uses of low-level laser therapy
    (2016) CHAVANTES, M. C.; PINTO, N. C.; HOLANDA, V. M.
    In our surgical experience, the use of low-level laser therapy (LLLT) can decrease complications in several major surgeries such as neurosurgery, major abdominal surgery (bariatric surgery), breast reconstruction (TRAM flap) surgical procedures, major burn surgery, and thoracic-cardiovascular surgery. LLLT can accelerate tissue repair, facilitating cicatrization and providing an analgesic effect in post-surgical pain. LLLT can also prevent morbidity, avoiding undesirable outcomes that could be evolving to post-operative death [1]. Although no single tool or technique is yet available to address the many complex issues surgeons face in their everyday practice, this remarkable devicemay be highly beneficial for patients by mitigating their suffering and quite rewarding for doctors. © 2017 Pan Stanford Publishing Pte.

    Customized Photobiomodulation Modulates Pain and Alters Thermography Pattern in Patients with Knee Osteoarthritis: A Randomized Double-Blind Pilot Study
    (2022) PINTO, Nathali Cordeiro; SOUSA, Marcelo Victor Pires de; FERREIRA, Nathalia Lopes; BRAGA, Natalia Almeida; ALDRED, Alexandre; GOMES, Guilherme; FREIRE, George Miguel Goes; ASHMAWI, Hazem Adel; CHACUR, Marucia
    Background: Photobiomodulation therapy (PBMT) modulates a wide variety of biological processes, leading to anti-inflammatory and analgesic effects. Understanding the mechanisms underlying therapeutic effects of PBMT remains challenging due to varying outcomes observed between wavelengths, dosage, and site of application. Our research group has dedicated close attention to customization and individualization of dosimetry for PBMT protocols. Preliminary data showed that using an individualized treatment could solve contradictory results reported by previous studies. Based on literature and our preliminary data on light absorption, the goal of the present pilot is to determine whether our individualized dosimetry is a feasible method to assist osteoarthritis (OA) pain control. Methods: This parallel two-arm controlled-pilot study aimed to assess whether personalized PBMT can be effective in the treatment of painful chronic knee OA. Thirty-one patients were randomly allocated into treatment and placebo group (sham irradiation), and the treatment procedure was performed twice a week, for 5 weeks. The PBMT was applied using 850nm with continuous wave and a total of 526-1402J each session. Individualized dosimetry was chosen based on each patient's body mass index and skin color. Quality-of-life (QOL) questionnaires and serum/urine analyses were performed before and after treatment was over. Both examiners and participants were blinded to group allocation. Results: Pain scores were reduced significantly in the 4th, 5th, and 10th sessions and remained lower 6 weeks posttherapy in the treatment group when compared to the placebo group. Moreover, the treatment group's results were improved in QOL questionnaires score, dopamine level, and in microcirculation. Conclusions: The present results provide initial evidence that customized photobiomodulation (PBM) reduce pain levels in short- and medium-term in patients with symptomatic knee OA when compared to placebo group. Furthermore, we have provided evidence that customized PBM is able to improve the QOL of those patients.

    The use of a high-power laser on swine mitral valve chordae tendineae
    (2016) PINTO, Nathali Cordeiro; CHAVANTES, M. Cristina; ZEZELL, Denise; DEANA, Alessandro; BENETTI, Carolina; MARCOS, Rodrigo Labat; LOPES, Luciana Almeida; MARTINS, Rodrigo A. B. Lopes; AIELLO, Vera Demarchi; JATENE, Fabio Biscegli; POMERANTZEFF, Pablo M. A.
    Worldwide, rheumatic fever remains a significant cause of mitral valve insufficiency. It is responsible for approximately 90 % of early childhood valvular surgeries in Brazil. Elongated or flail chordae are frequently responsible and require surgical correction. The purpose of this study was to analyze and compare the histological tissues of the mitral valve chordae and the mechanical resistance generated by the chordae, both with and without the application of a high-power laser. Twenty normal porcine mitral valve chordae were measured and divided randomly into the following two groups: control group (not subjected to a high-power laser) and laser group (subjected to photonic irradiation). Laser surgery was performed under controlled conditions, using following parameters: lambda = 980-nm wavelength, power = 3 W, and energy = 60 J. A mechanical test machine was used in combination with a subsequent histological study to measure chordae tensile properties. A histological analysis demonstrated a typical collagen bundle arrangement in the control group; however, under a particular reached temperature range (48), the collagen bundles assumed different arrangements in the laser group. Significant reductions in the chordae tendineae lengths and changes in their resistance in the laser group were observed, as these chordae exhibited less rigid fibers. The chordae tendineae of normal porcine valves subjected to a high-power laser exhibited its length reduction and less stiffness compared to the control group. A histological analysis of the laser treatment specimens demonstrated differences in collagen bundle spatial organization, following slight changes into tissue temperature.
