RESUMO
BACKGROUND: This aim of this study was to assess and compare arterial and venous circulation in women with axillary lymph node dissection (ALND) and sentinel lymph node biopsy (SLNB) before and after breast cancer surgery. METHODS AND RESULTS: Fifty-two women took part in the study, divided into three groups: those undergoing ALND at levels I, II, and III (ALNDG), with mean age of 56.29 ± 10.85 years old; those undergoing sentinel lymph node biopsy (SLNBG), with mean age of 57.7 ± 7.07 years old; and controls without diagnosis of breast cancer (CG), with mean age of 53.92 ± 8.85 years old. Maximum venous and arterial flow velocities in upper limbs were assessed before and after surgical treatment for breast cancer by means of Doppler ultrasonography (Nicolet Vascular Versalab SE®). Data normality was assessed by using the Shapiro-Wilk's test, with normally distributed variables being analyzed with analysis of variance (ANOVA) and post hoc Tukey's test or t-test. For variables with non-normal distribution, Kruskal-Wallis' test and post hoc Dunn's test were used at p < 0.05. There was significant difference in the maximum blood flow velocities, both venous (ALNDG) and arterial (SLNBG). CONCLUSION: The results suggest that ALND and SLNB can interfere with the upper limp blood circulation.

BACKGROUND: Infrared thermography is recognized as a viable method for evaluation of subjects with myofascial pain. OBJECTIVE: The aim of the present study was to assess the intra- and inter-rater reliability of infrared image analysis of myofascial trigger points in the upper trapezius muscle. METHOD: A reliability study was conducted with 24 volunteers of both genders (23 females) between 18 and 30 years of age (22.12 ± 2.54), all having cervical pain and presence of active myofascial trigger point in the upper trapezius muscle. Two trained examiners performed analysis of point, line, and area of the infrared images at two different periods with a 1-week interval. The intra-class correlation coefficient (ICC(2,1)) was used to assess the intra- and inter-rater reliability. RESULTS: With regard to the intra-rater reliability, ICC values were between 0.591 and 0.993, with temperatures between 0.13 and 1.57 °C for values of standard error of measurement (SEM) and between 0.36 and 4.35 °C for the minimal detectable change (MDC). For the inter-rater reliability, ICC ranged from 0.615 to 0.918, with temperatures between 0.43 and 1.22 °C for the SEM and between 1.19 and 3.38 °C for the MDC. CONCLUSION: The methods of infrared image analyses of myofascial trigger points in the upper trapezius muscle employed in the present study are suitable for clinical and research practices.

OBJECTIVE: To assess the influence of diabetic neuropathy (DN) on balance and functional strength in patients with diabetes mellitus type 2 (DM2). DESIGN: Cross-sectional study. SETTING: Diabetes outpatient unit. PARTICIPANTS: Adults (N=62; age range, 40-65y): 32 with DM2 (19 subjects without DN and 13 with DN) and 30 without DM2 (control group). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Upright balance, evaluated in 4 situations (fixed platform, unstable platform, with eyes open, with eyes closed), and functional strength, assessed with a five-times-sit-to-stand test, were analyzed using an electromagnetic system, with a sensor placed over C7 to allow maximum trunk displacements in the anterior-posterior and medial-lateral directions. The Berg Balance Scale and the Timed Up & Go test were also used. RESULTS: Subjects with DM2 had greater anterior-posterior displacement (P<.05) in the unstable platform with eyes closed condition compared with those without DM2, whereas no difference in medial-lateral displacement was observed between these groups. A difference in time was observed in the five-times-sit-to-stand test (P<.05), with subjects in the control group performing the tasks faster than either group of subjects with DM2. Additionally, subjects in the control group showed a higher score in the Berg Balance Scale and performed the Timed Up & Go test in less time compared with subjects in other groups. CONCLUSIONS: Subjects with DM2, with or without DN, showed deficits in postural control and functional strength compared with healthy individuals of the same age group.
