Item Photobiomodulation applied in post-surgical female-to-male surgery: case report(Erciyes Üniversitesi) Arisawa, Emilia Angela Lo Schiavo; Martins, Rodrigo Álvaro Lopes; Martins, Patrícia Sardinha Leonardo Lopes; Meneguzzo, Daiane Thais; Arisawa, Ana Amélia Lo Schiavo; Gallagher, SidhbhPhotobiomodulation (PBM) is an emerging medical technology with therapeutic effects that reduce or inhibit inflammatory mediators and cytokines, decreasing pain and local edema. However, the number of papers reporting the application of PBM in the post-surgical period is still scarce. This case report aims to evaluate the action of PBM applied after bilateral mastectomy with free nipple grafts regarding collateral effects such as pain, edema and hematoma. Patients underwent breast surgery with free nipples grafts. PBM sessions were applied 5, 24, 48 and 72 hours after surgery using a diode laser Platinum 4 equipment with four wavelengths (650, 810, 915 and 980 nm). Total energy applied was 1080 Joules distributed in six minutes of laser application over lymph node areas and the suture region. Both patients (A and B) related pain relief after PBM sessions (5, 24, 48 and 72 hours) after surgery. Also nipple sensitivity and overflow of reddish-color were reduced after 72h. The application of PBM reduced pain intensity and nipples hypersensitivity, suggesting reduction of inflammatory process. The benefits reported in this study suggest the indication of this complementary therapy to cosmetic procedures for transgender people.Item Kinematic and sensory-motor analysis of the effects of treatments with photobiomodulation in rats with experimentally induced spinal injury(Springer Nature Link) Beloni, Luís Filipe Karatanasov; Lima, Leonardo Borges de; Correia, Débora Campos Chaves; Mendes, Alessandro Corrêa; Sannt'Anna, Luciana Barros; Arisawa, Emilia Angela Lo Schiavo; Lima, Fernanda Pupio Silva; Lima, Mario OliveiraThe aim of this study was to evaluate the kinematic and sensorimotor parameters after application of photobiomodula- tion (PBM) in rats with experimentally induced spinal cord injuries (SCI). The animals were randomly divided into 3 experimental groups containing 5 animals each and respecting the following arrangement: C (control, simulation of sur- gical procedures); I (injury, induction of SCI) and PBM (photobiomodulation, SCI+application of photobiomodulation therapy). All animals underwent movement tests after 3, 7, 10 and 14 days, respectively, after the surgical procedure, and the following movement parameters were evaluated: mean velocity (MV), ground reaction force (GRF) and sciatic func- tional index (SFI) using integrated equipment capable of digitally collecting the proposed data. The mean results of the MV data obtained by groups C, I and PBM were compared and a statistically significant difference was found, being: C x I (p=0.001) and I x PBM (p=0.002), respectively. Considering the SFI data obtained by groups C, I and PBM, a statisti- cally significant difference was observed when comparing C x I (p = 0.011). The mean results of the GRF data obtained by groups C, I and PBM were compared and the results showed a statistically significant difference in C x I (p=0.001), C x PBM (p=0.026) and I x PBM (p=0.002), respectively. Therefore, there was an improvement in motor function between the 7th and 14th day after SCI, represented by the increase in speed and better GRF distribution in the PBM group.
