RESUMO

INTRODUCTION: Breast cancer affects women of different ages, and comorbidities resulting from treatment can affect postural stability. The study aimed to evaluate the influence of age and lymphedema on the postural balance of women undergoing breast cancer treatment. METHODS: The study included 77 women undergoing breast cancer treatment, divided into different groups: 37 young adult women divided into 17 with lymphedema (GYL) and 20 young adults without lymphedema (GY); 40 elderly women, 20 elderly women with lymphedema (GEL) and 20 elderly women without lymphedema (GE). Mini Balance Evaluation Systems Test (Mini BESTest) and Falls Efficacy Scale - International (FES-I) were used. RESULTS: Mini BESTest and FES-I between the groups showed that GE and GEL had a significant difference to GY. Mini BESTest Total and Time Up and Go TUG-Double Task showed that GE has a significant difference to GYL, with GE and GEL having lower scores. Moderate negative correlation in the GEL between FES-I and Mini BESTest. In the age correlation between the Mini BESTest, FES-I, TUG, and double task TUG, a moderate positive correlation was observed for TUG. GEL showed a moderate positive correlation for FES-I and double-task TUG, strong for TUG, and moderate negative correlation with Mini BESTest. Correlation of the volume difference between the limb affected and not affected by lymphedema and the FES-I, Mini BESTest, TUG, and TUG double task, GYL showed moderate negative correlation for TUG. CONCLUSION: Age and lymphedema influenced the dynamic postural balance of women undergoing breast cancer treatment.

RESUMO

OBJECTIVE: What are the immediate, short-term, and long-term effects of complex physical therapy and multimodal approaches on lymphedema secondary to breast cancer? DATA SOURCES: Four electronic databases (MEDLINE, Embase, Cochrane Library, Physiotherapy Evidence Database) were searched from inception up to August 2020. STUDY SELECTION: Randomized controlled trials comparing complex physical therapy and multimodal approaches to the conservative treatment of lymphedema secondary to breast cancer. DATA EXTRACTION: Two independent researchers performed data extraction and assessed the risk of bias, respectively, using the predefined form and Cochrane Collaboration of Risk of Bias. The determination of evidence quality was carried out using the Grading of Recommendations Assessment, Development, and Evaluation tools. DATA SYNTHESIS: Fourteen studies were identified for the systematic review and 11 studies for the meta-analysis with standardized mean difference (SMD), 95% CI, and random-effect model. The common outcomes involved total volume, pain, and physical function of the upper limb. Complex physical therapy has shown a favorable tendency to control outcomes in the short- and long-term. The meta-analysis indicated a small effect for volume reduction (SMD, -0.18; 95% confidence interval [CI], -0.35 to 0.00) and a moderate effect for short-term pain reduction (SMD, -0.61; 95% CI, -1.19 to -0.02). CONCLUSIONS: High-quality evidence suggests a more significant effect of complex physical therapy on multimodal approaches to the control of the upper limb total volume, substantiating the absence of changes in the current clinical practice in the management of lymphedema secondary to breast cancer. Future research should aim to identify concrete effect of therapeutic modalities in the immediate-, short-, and long-term.

RESUMO

INTRODUCTION: This study aimed to assess the static posture in patients with Angle Class II and III malocclusions in the first 2 months after orthognathic surgery. METHODS: This was a longitudinal observational study. Eligible participants were adult patients who had an indication of orthognathic surgery (bilateral sagittal split osteotomy of the maxilla and/or mandible, can be associated or not with genioplasty). Thirty-five patients were evaluated from the orthognathic surgery group (OSG) and control group (CG). Measurements in OSG were performed at 3 time points: preoperative orthognathic surgery (P0), first postoperative month (P1), and second postoperative month (P2). Static posture was evaluated using the PostureScreen Mobile (PostureCo Inc, Trinity, Fla) application in 4 views. RESULTS: Patients with Angle Class II malocclusion in the OSG evidenced a tendency to a left hip translation at P1 with a significant difference at P2 in the anterior view (P = 0.052). In the right lateral view, patients with Angle Class II malocclusion in the OSG at P1 presented an accentuated anterior shoulder translation when compared with CG (P <0.001). At P1, patients with Angle Class II malocclusion in the OSG showed a significant anterior knee translation compared with the CG and OSG at P0 and P2 (P <0.001 for all). Patients in the OSG with Angle Class III malocclusion presented an average posterior head translation in the right lateral view at P1 when compared with those in the CG and OSG at P0, who presented an anterior translation (P = 0.0008). CONCLUSIONS: These findings suggest a realignment of static posture in the first 2 months after orthognathic surgery.

RESUMO

BACKGROUND: With the increase in survival of women treated for breast cancer, it is necessary to evaluate the effect of therapeutic resources on co-morbidities resulting from the surgical treatment of the disease. The aim of this study was to evaluate the effects of proprioceptive neuromuscular facilitation on the functionality and lymphatic circulation of the upper limb involved in the treatment of breast cancer. METHODS: The study was conducted according to randomized clinical trial design. Thirty-two women at a mean age of 52.20 (±8.32) years, submitted to breast cancer treatment, divided into two groups, control - women submitted to standard breast cancer treatment, and treated group, composed of women who underwent breast cancer treatment and rehabilitation with the proprioceptive neuromuscular facilitation technique. Palmar grip strength with dynamometer and shoulder range of motion with goniometer were evaluated. Lymphatic circulation analysis was performed in a computerized scintillation chamber, before and after therapeutic intervention. FINDINGS: In the results obtained, a significant increase (p < 0.05) of palmar grip strength was observed, a significant increase in range of motion of flexion (p < 0.001), extension (p < 0.0012), abduction (p < 0.0001), external rotation (p < 0.0001), internal rotation (p < 0.0001), and not significant for lymphatic flow (p > 0.05). INTERPRETATION: The results obtained in this study allow us to conclude that proprioceptive neuromuscular facilitation favors an increase in muscle strength, range of motion, but not in lymphatic flow, in women undergoing surgical treatment for breast cancer.

RESUMO

BACKGROUND: In recent decades, low-level laser therapy (LLLT) has occupied a prominent position and has been studied in various fields of knowledge, and your effects have been widely observed in studies about numerous tissues, such as tendons, peripheral nerves, cutaneous tissue, bone, and muscle, in different fields of knowledge. PURPOSE: To analyze the power transmitted by low-level laser therapy (LLLT) to different tissue samples by using distinct wavelengths. METHODS: Skin samples of rat (n = 7, 1.17-1.63 mm) and pig (n = 10; 1.20-2.30 mm); pig fat (n = 10; 2.71-14.01 mm) and pig muscle (n = 10; 1.91-8.91 mm) were analyzed and interposed between the emitter and the power analyzer sensor. All the samples were irradiated sequentially three times, at five equidistant points and average power levels of 35.34(±1.03), 32.40(±0.70), and 42.32(±0.82) mW, for the wavelengths 660, 830, and 904 nm, respectively. Transmitted radiation was measured with a power analyzer connected to a laser emitter. Statistical analysis was performed with a Shapiro-Wilk test followed by ANOVA with Tukey's post hoc test, with a significance level of 5%. RESULTS: The transmitted power of LLLT on skin, fat, and muscle of tissues decreases with the increase of thicknesses, presenting minor attenuation on rat skin, pig fat, and pig muscle for 904 nm. The pig skin has the slight attenuation for 830 nm. CONCLUSION: The LLLT should be applied after considering the transmission loss taking place in different anatomical structures, following the Beer-Lambert law and attenuation coefficient presented for more practical application in many fields.

RESUMO

Abstract Introduction: Obesity is a contributing factor to the development of urinary incontinence (UI). Objective: The objective of this study was to evaluate the prevalence of UI symptoms in women with morbid obesity and their impacts on quality of life (QOL), correlating the influence of age and body mass index (BMI) with the presence of UI. Method: Sixty-five women undergoing preoperative bariatric surgery, aged 35.8 ± 9.97 years, with an average BMI of 45.04 ± 6.79 kg/m2 were asked about the presence of UI symptoms; when they answered positively, the King's Health Questionnaire (validated into Portuguese) was applied. The questionnaire was self-administered and all answers were assigned numerical scores. These scores were distributed according to quartiles and correlated with age and BMI. The level of hypothesis rejection was 5%, and analyses were performed using BioEstat software version 5.3. Results: Among 65 interviewees, 19 (29.23%) had symptoms of UI and went on to answer the questionnaire. The highest-scoring areas were "incontinence impact" (36.8) and "general health perception" (32.9). There was no significant correlation between questionnaire scores and BMI. In the association with age, the "incontinence impact" domain showed a significant, positive and moderate correlation (r = 0.52; p = 0.02). Conclusion: The prevalence of UI symptoms in the sample had a slight negative effect on QOL; however, UI associated with older ages significantly affected the QOL of the studied volunteers.


Resumo Introdução: A obesidade é considerada um fator contribuinte para o desenvolvimento da incontinência urinária (IU). Objetivo: O objetivo deste estudo foi avaliar a prevalência dos sintomas da IU em mulheres obesas mórbidas, seu impacto sobre a qualidade de vida (QV) e correlacionar a influência da idade e do índice de massa corporal (IMC) sobre a presença de IU. Método: Foram avaliadas, 65 mulheres, em pré-operatório de cirurgia bariátrica, com idade de 35,8±9,97 anos e IMC de 45,04±6,79 kg/m 2 sendo questionadas sobre sintomas de IU e, se confirmados, responderam ao King's Health Questionnaire, validado para o português. O questionário foi auto administrado e foram atribuídos valores numéricos às respostas, esses escores foram avaliados em quartis e correlacionados com a idade e o IMC. O nível de rejeição da hipótese foi 5% e as análises foram realizadas com o software BioEstat, versão 5.3. Resultados: Das 65 mulheres que foram entrevistadas, dezenove delas (29,23%) apresentaram os sintomas da IU e responderam ao questionário. Os domínios que apresentaram maior pontuação foram "impacto da IU" (36,8) e "percepção geral da saúde" (32,9). Não foi encontrada correlação significativa entre os escores do questionário e o IMC. Já na associação com a idade, o domínio "impacto da IU" apresentou correlação positiva, significativa e moderada (r = 0,52; p = 0,02). Conclusão: Diante dos achados, com a prevalência de sintomas de IU na amostra estudada, pode-se inferir que a IU compromete pouco a QV, entretanto o aumento da idade quando associada à IU pode afetar significativamente a QV de mulheres obesas classe II e III.

RESUMO

Breast cancer is the most common cancer affecting women in the world and provides functional changes in the human body. Evaluate women submitted to unilateral mastectomy, through electromyographic activity (mandibular rest, right and left laterality, protrusion, maximum voluntary contraction with and without Parafilm, habitual and non-habitual mastication) and thickness (rest and maximum voluntary contraction) of the right temporal muscle (RT), left temporal (LT), right masseter (RM) and left masseter (LM), also the molar bite force (right and left) and compare the data with healthy women. Material and Methods: 32 women were divided into two groups: unilateral mastectomy group (MG), average ± standard deviation 56.50±14.50 years (n=16) and without the disease group (CG), average ± standard deviation 56.56±14.15 years (n=16). The normalized electromyographic data, muscle thickness and maximal molar bite force were tabulated and submitted to statistical analysis (SPSS 21.0; student t test, p≤0.05). Significant statistical differences between MG and CG were found in right laterality, for RM (p=0.02); left laterality, for LT (p=0.01); chewing with peanuts, for RM (p=0.04); chewing with raisins, for LM (p=0.04) and right molar bite force (p=0.03). There was no statistically significant difference between MG and CG for muscle thickness. The results of this study suggest that women undergoing unilateral mastectomy may present functional changes, with emphasis on muscular hyperactivity, lower masticatory efficiency and lower maxillary bite force.

Resumo Câncer de mama é a neoplasia mais comum que mais acomete mulheres no mundo e proporciona alterações funcionais no corpo humano. Objetivo: avaliar mulheres submetidas à mastectomia unilateral, por meio da atividade eletromiográfica (repouso mandibular, lateralidade direita e esquerda, protrusão, contração voluntária máxima com e sem parafilme, mastigação habitual e não habitual) e espessura (repouso e contração voluntária máxima) do músculo temporal direito (TD), temporal esquerdo (TE), masseter direito (MD) e masseter esquerdo (ME), além da força de mordida molar (direita e esquerda) e comparar os dados com mulheres saudáveis. 32 mulheres foram distribuídas em dois grupos: grupo mastectomia unilateral (GM), média ± desvio padrão 56,50 ± 14,50 anos (n=16) e grupo sem a doença (GC), média ± desvio padrão 56,56 ± 14,15 anos (n=16). Os dados eletromiográficos normalizados, espessura muscular e força de mordida molar máxima foram tabulados e submetidos à análise estatística (SPSS 21.0; teste t de student, p≤0,05). Foram encontradas diferenças estatísticas significantes entre GM e GC na lateralidade direita, para o MD (p=0,02); lateralidade esquerda, para o TE (p=0,01); mastigação com amendoim, para o MD (p=0,04); mastigação com uva-passa, para o ME (p=0,04) e força de mordida molar direita (p=0,03). Não houve diferença estatística significante entre GM e GC para espessura muscular. Os resultados deste estudo sugerem que mulheres submetidas à mastectomia unilateral podem apresentar alterações funcionais do sistema estomatognático, com destaque para hiperatividade muscular, menor eficiência mastigatória e menor força de mordida molar máxima.

RESUMO

OBJECTIVE: To analyze the effects of Lower Limb (LL) auricular stimulation points on the static equilibrium of healthy subjects, assessed by computerized baropodometry. METHODS AND MATERIALS: Forty volunteers were assigned to one of two groups: Auriculotherapy (AT) who received unilateral needle stimulation of the coxofemoral, knee, and ankle points. Control (C) who did not receive any stimulation. We analyzed the contact area (CA) and the peak pressure (PP) for both feet at baseline, 20 and 25 min after the baseline was recorded. Three-Way ANOVA (P < 0.05) was used for data analysis. RESULTS: AT showed an increase in CA (F:6.49) and a decrease in PP (F:3.11) at 20 and 25 min, when compared to C. The PP decreased was only for the right LL at 20 and 25 min (F:6.45). CONCLUSION: The auriculotherapy points were able to modify the ipsilateral weight discharge on the same side of the stimulated auricular pavilion.

RESUMO

OBJECTIVE: assess the effects of ischemic compression and kinesiotherapy on the rehabilitation of breast cancer survivors with chronic myofascial pain. METHODS: A randomized, controlled, blinded clinical trial was performed with 20 breast cancer survivors with myofascial trigger point in the upper trapezius muscle. Patients were randomly allocated to ischemic compression + kinesiotherapy (G1, n = 10) and kinesiotherapy (G2, n = 10). Both groups were submitted to 10 sessions of treatment. The variables evaluated were: Numeric Rating Scale, Pain Related Self-Statement Scale, pressure pain threshold, Functional Assessment of Cancer Therapy-Breast and Infrared thermography. RESULTS: A significant reduction (p < 0.05) was observed in pain intensity after 10 sessions in Groups 1 and 2, a significant increase (p < 0.05) in pressure pain threshold in both the operated and non-operated side after 10 sessions for Group 1. CONCLUSION: Ischemic compression associated with kinesiotherapy increases the pressure pain threshold on the myofascial trigger point in the upper trapezius muscle and reduces the intensity of pain in breast cancer survivors with myofascial pain.

RESUMO

The objective of the study was to evaluate the intra- and inter-rater reliability of bioimpedance in determining upper limb volume in women with lymphedema resulting from breast cancer treatment, as well as its correlation with the upper limb volume calculated by circumferential measurement. A blind cross-sectional study was performed in which 27 women (62.59 ± 10.50 years) were evaluated with upper limb lymphedema secondary to breast cancer treatment. Two examiners performed assessments in the same volunteers independently and twice, with an interval of 1 week between assessments. The collections were performed by the direct tetrapolar multifrequency segmental bioimpedance and by the circumference of the upper limb homolateral to the breast cancer. The results of the circumference showed that the homolateral limb had lymphedema. The intra- and inter-rater analysis showed excellent reliability with intraclass correlation coefficient (ICC) values ranging from 0.954 to 0.999 for the amount of liquid and excellent reliability with ICC values ranging from 0.852 to 0.999 for the electrical impedance of the upper limb with lymphedema. The correlation was strong and negative (p < 0.05) between intracellular, extracellular, and total water when associated with electrical impedance and moderate and positive (p < 0.05) when associated with upper limb volume for all frequencies. The correlations between upper limb volume and water quantities were moderate and positive (p < 0.05). The results indicate that bioimpedance is a reliable method for the evaluation of lymphedema, and the volume of the homolateral upper limb is associated with the amount of water in women with lymphedema secondary to the treatment of breast cancer.

RESUMO

BACKGROUND: Shortwave diathermy (SWD) and microwave diathermy (MWD) are frequently used by physical therapists to treat musculoskeletal conditions. The therapeutic benefits are usually associated with an increase in tissue temperature; however, there is no consensus on the changes in blood flow. OBJECTIVES: 1) To evaluate the behavior of temperature and arterial blood flow after the application of SWD and MWD to the lower limb of healthy women aged 18-30 and 2) to assess whether changes in limb positioning can influence SWD response. METHOD: Among the subjects analyzed, 40 women were eligible to participate in the trial and were randomly allocated to the SWD group or the MWD group. Each group received 20min of diathermy. After receiving the interventions, all patients crossed over to the other group, but the devices were detuned (sham). SWD was applied to the posterior compartment of the thigh and leg, with the knee in 0° and 90° of flexion, and the MWD applied to the posterior thigh. Skin temperature evaluation (digital infrared thermography) and assessment of blood flow velocity (Doppler ultrasound) were performed immediately before and 10 and 20min after the application. RESULTS: Arterial blood flow increased after SWD diathermy (vs. Sham), but not after MWD diathermy. SWD promoted skin heating at the end of therapy in all areas analyzed, remaining above baseline even 20min after the end of the application. MWD diathermy promoted skin heating in the posterior thigh, reflecting a rise in the temperature of the popliteal fossa area that remained for 10min after the end of the application. CONCLUSION: The increase in arterial blood flow velocity depends on the size of the heating area, since it was only observed in the application of the SWD. However, after 20min of application, the position of the lower leg did not affect the heating.

RESUMO

OBJECTIVE: The purpose of this study was to correlate upper limb volume and arterial and venous blood flow velocity in breast cancer survivors. METHODS: A cross-sectional study was conducted on 30 women with lymphedema and a mean age of 55.60 years (standard deviation = 8.12). For the assessment of upper limb volume, perimetry was performed with measures at 6 points on the limb, which were mathematically calculated as volume. The blood flow velocity of the axillary and brachial arteries and veins were assessed by Doppler ultrasound with a probe at 4 MHz. In the statistical analysis, a Shapiro-Wilk test determined a non-normal data distribution. Spearman correlation coefficients (ρ) were calculated to determine the association between the variables blood flow velocity and lymphedema volume. RESULTS: We identified significant and positive associations between all variables correlated with limb volume: blood flow velocity of the axillary artery (ρ = 0.381, P = .041), axillary vein (ρ = 0.383, P = .039), brachial artery (ρ = 0.375, P = .044), and the brachial vein (ρ = 0.373, P = .045). CONCLUSION: There is a positive association between limb volume and blood flow velocity in the upper limbs of women with lymphedema secondary to breast cancer treatment.

RESUMO

OBJECTIVE: The purpose of this study was to assess blood flow after manual lymphatic drainage (MLD) in women who had received surgery for breast cancer and had post-axillary lymphadenectomy lymphedema. METHODS: Sixteen volunteers (mean age 64 ± 11.44 years) were divided into 2 groups. Those in group 1 received MLD without upper limb elevation, and those in group 2 received MLD with elevation of 30° of the upper limb. Blood flow velocity of the brachial vein and artery were measured using Doppler ultrasound before, immediately after, and 30 minutes after MLD, with and without 30° of upper limb elevation as defined by a random crossover design and an interval (washout) of 7 days. Comparison of data before and after MLD was evaluated by the Friedman test. RESULTS: There was a significant increase of blood flow velocity in the brachial vein after the therapeutic procedure with upper limb elevation. However, after 30 minutes the data returned to the pretreatment value. CONCLUSION: This preliminary study indicated that MLD promoted increased brachial vein velocity flow in the short term.

RESUMO

OBJECTIVE: Although it is possible to find studies that analyze the velocity of blood flow in different arteries, the reliability of Doppler ultrasound on peripheral arteries has not yet been completely established. Our objective was to evaluate intra- and inter-rater reliability of the measurement of blood flow velocity by Doppler ultrasound of brachial, radial, popliteal, and posterior tibial arteries. METHODS: Fifty healthy individuals of both genders, aged between 18 and 45 years, were included in the study. For the evaluation of arterial blood flow velocity, a portable Doppler ultrasound device was used to measure the mean and maximum blood flow velocity of posterior tibial, popliteal, brachial, and radial arteries. Two examiners performed assessments of the same volunteers independently and twice, with an interval of 1 week between them. RESULTS: We found good to very good reliability for measuring the mean and maximum blood flow velocity of the arteries evaluated. The intraclass correlation coefficients ranged between 0.501 and 0.866, standard error of measurement ranged between 0.81 and 9.45 cm/s, and minimum detectable change ranged between 2.25 and 26.13 cm/s. CONCLUSION: The assessment of mean and maximum blood flow velocity of the brachial, radial, popliteal, and posterior tibial arteries by means of Doppler ultrasound presents acceptable reliability values, which supports the use of this evaluation method in research and clinical practice.

RESUMO

The purpose of this study is to investigate the effect of pulsed electrical field (PEF) and photobiomodulation laser (PBM) on the viability of the TRAM flap in diabetic rats. Fifty Wistar rats were divided into five homogeneous groups: Group 1-control; Group 2-diabetics; Group 3-diabetics + PEF; Group 4-diabetic + laser 660 nm, 10 J/cm2, 0.27 J; Group 5-diabetic + laser 660 nm, 140 J/cm2, 3.9 J. The percentage of necrotic area was evaluated using software Image J®. The peripheral circulation of the flap was evaluated by infrared thermography FLIR T450sc (FLIR® Systems-Oregon USA). The thickness of the epidermis (haematoxylin-eosin), mast cell (toluidine blue), leukocytes, vascular endothelial growth factor, fibroblast and newly formed blood vessels were evaluated. For the statistical analysis, the Kruskal-Wallis test was applied followed by Dunn and ANOVA test followed by Tukey with critical level of 5% (p < 0.05). The PEF reduced the area of necrosis, decreased the leukocytes, increased the mast cells, increased the thickness of epidermis and increased newly formed blood vessels when it was compared to the untreated diabetic group of animals. Laser 660 nm, fluence 140 J/cm2 (3.9 J) showed better results than the 10 J/cm2 (0.27 J) related to reduction of the area of necrosis and the number of leukocytes, increased mast cells, increased thickness of the epidermis, increased vascular endothelial growth factor, increased fibroblast growth factor and increase of newly formed blood vessels in diabetic animals. The laser and pulsed electrical field increase the viability of the musculocutaneous flap in diabetic rats.

RESUMO

The aim of this study was to investigate the effect of laser photobiomodulation (PBM) on the viability of the transverse rectus abdominis musculocutaneous (TRAM) flap in rats subjected to the action of nicotine. We evaluated 60 albino Wistar rats, divided into six groups of ten animals. Group 1 (saline) underwent the surgical technique to obtain a TRAM flap; group 2 (laser 830 nm) underwent the surgical technique and was irradiated with a laser 830 nm; group 3 (laser 660 nm) underwent the surgical technique and was irradiated with a laser 660 nm; group 4 was treated with nicotine subcutaneously (2 mg/kg/2×/day/4 weeks) and underwent surgery; group 5 (nicotine + laser 830 nm) was exposed to nicotine, underwent the surgical technique, and was irradiated with a laser 830 nm; group 6 (nicotine + laser 660 nm) was exposed to nicotine, underwent the surgical technique, and was irradiated with a laser 660 nm. The application of PBM occurred immediately after surgery and on the two following days. The percentage of necrosis was assessed using the AxioVision® software. The number of mast cells (toluidine blue staining) was evaluated, and immunohistochemistry was performed to detect vascular endothelial growth factor expression (anti-VEGF-A), fibroblasts (anti-basic FGF), and neoformed vessels (anti-CD34). PBM with a wavelength of 830 nm increased the viability of the TRAM flap, with a smaller area of necrosis, increased number of mast cells, and higher expression of VEGF and CD34. PBM increases the viability of musculocutaneous flaps treated with to nicotine.

RESUMO

RESUMO O objetivo deste estudo foi avaliar o efeito da estimulação elétrica de alta voltagem (EEAV) catódica, associada à insulina tópica, em lesão tegumentar de ratos. Para isso, foram utilizados 42 ratos Wistar (240±30 g), submetidos a retirada cirúrgica de 1 cm2 de pele do dorso em seis grupos (n=7), tratados por sete dias consecutivos: controle (C), estimulação elétrica placebo (EP), estimulação elétrica catódica (EE), insulina tópica (IT), insulina placebo (IP) e EEAV associada a insulina tópica (EE+I). A EEAV foi administrada 24 horas após a cirurgia, 30 minutos por dia, com frequência de 100 Hz e voltagem média de 60 V, mantida no limiar motor. Áreas das lesões foram registradas macroscopicamente no primeiro, quarto e oitavo dia, sendo submetidas a tratamento histológico para inclusão em paraplast® e coloração em hematoxilina e eosina. A epitelização e o perfil numérico das células foram obtidos por análises histométricas. Utilizou-se o teste de Shapiro-Wilk e ANOVA one-way seguida de Bonferrone (p<0,05). Observou-se redução significativa na área da lesão no oitavo dia de tratamento, nos grupos EE e EE+I em relação aos demais grupos. A reepitelização não diferiu entre os grupos, mas a distância entre as bordas da lesão foi menor nos grupos EE e EE+I. Nesses grupos houve aumento significativo (p<0,05) no número de fibroblastos e diminuição de leucócitos. Pode-se concluir que a EEAV catódica acelerou o processo de reparação da lesão, não demonstrando efeito adicional com a aplicação da insulina tópica.

Para ello, se utilizaron 42 ratas Wistar (240±30 g), les sometieron a cirugía de retirada de 1 cm2 de piel del dorso en 6 grupos (n=7), y les trataron por siete días consecutivos: control (C), estimulación eléctrica placebo (EP), estimulación eléctrica catódica (EE), insulina tópica (IT), insulina placebo (IP) y EEAV asociada a la insulina tópica (EE+I). Se aplicó la EEAV 24 horas después de la cirugía, 30 minutos por día, con frecuencia de 100 Hz y voltaje de media tensión de 60 V, y la mantuvo en el umbral motor. Se registraron las áreas de las lesiones macroscópicamente en el primer, cuarto y octavo día, y las sometieron al tratamiento histológico para inclusión en paraplast® y tinción hematoxilina-eosina. Se obtuvo la epitelización y el perfil numérico de las células por análisis histométricos. Se empleó la prueba Shapiro-Wilk y ANOVA one way de Bonferroni (p<0,05). Se redujo significativamente el área de la lesión en el octavo día del tratamiento en los grupos EE y EE+I comparados a los demás grupos. La reepitalización no fue distinta entre los grupos, sin embargo, la distancia entre los bordes de la lesión fue menor en los grupos EE y EE+I. También en estos grupos aumentó significativamente (p<0,05) el número de fibroblastos y disminuyeron los leucocitos. Se concluye que la EEAV catódica aceleró el proceso de reparación de la lesión, pero no ocurrió resultado con la aplicación de la insulina tópica.


ABSTRACT This study aims to evaluate the effect of cathodic high voltage electrical stimulation (HVES), associated with topical insulin, on rat integumentary lesions. For this purpose, 42 Wistar rats (240±30 g) were submitted to surgical removal of 1 cm2 of dorsal skin and divided into six groups (n=7), treated for seven consecutive days: Control (C), placebo electrical stimulation (PES), cathodic electrical stimulation (ES), topical insulin (TI), placebo insulin (PI) and HVES associated with topical insulin (ES+I). HVES was administered 24 hours after surgery, 30 minutes per day, with a frequency of 100 Hz and a mean voltage of 60 V, maintained at the motor threshold. Lesion areas were recorded macroscopically on the first, fourth and eighth day, submitted to histological treatment for inclusion in paraplast® and staining in Hematoxylin and Eosin. Epithelialization and the numerical profile of the cells were obtained by histometric analysis. The Shapiro-Wilk and Anova one-way test was followed by the Bonferroni (p<0.05). There was a significant reduction in the area of the lesion by the eighth day of treatment, both in the ES and ES+I groups, when compared with other groups. Reepithelialization did not differ between groups, but the distance between the edges of the lesion was lower in the ES and ES+I groups. These same groups showed a significant increase (p<0.05) in the number of fibroblasts and a decrease in leukocytes. Thus, we can conclude that cathodic HVES accelerated the lesion repair process, with the topical application of insulin showing no additional effect.

RESUMO

BACKGROUND: Low-intensity pulsed ultrasound (LIPUS) has presented good results in the healing of chronic wounds. The objective of this study was to compare the effect of LIPUS on the viability of transverse rectus abdominal muscle (TRAM) flap in different regions (central and epigastric) in rats. METHODS: Twenty-one Wistar male rats were homogeneously distributed into three groups as follows: group 1 (control), animals submitted to surgery only; group 2, animals submitted to surgery and application of LIPUS at the center of the flap; and group 3, animals submitted to surgery and application of LIPUS at the flap area corresponding to the right inferior epigastric artery pedicle. Stimulation was performed immediately after the surgery and within the following 2 days. The percentage of flap necrosis was evaluated by using the ImageJ® software as well as by measuring the temperature variation with infrared thermography (FLIR® T300). RESULTS: In the percentage calculation of the necrosis area, the application of LIPUS at the center of the flap (group 2) showed significantly smaller difference (26.2 %) compared to group 1 (54.50 %) and group 3 (44.01 %). Analysis of the temperature variation between the groups was performed by using the one-way ANOVA followed by Tukey's test. The results showed that both forms of LIPUS application showed significant differences compared to the control group. CONCLUSIONS: In view of our results, one can conclude that the application of LIPUS at the center of the flap was effective for the viability of TRAM flap in reducing the necrosis area.
