Abstract
Branched-chain amino acids increase the brain perfusion of patients with hepatic encephalopathy (HE), but the amino acid and the mechanisms involved are still unknown. This study compared brain perfusion and clinical improvement during leucine or isoleucine supplementation. After randomization, 27 subjects with cirrhosis and HE received leucine or isoleucine supplements for one year. Brain single Photon Emission Computed Tomography (SPECT) and dynamic brain scintigraphy (DBS) were performed pretreatment and at 1, 8 and 12 months of supplementation. Brain perfusion was increased only in the isoleucine group at 8 months of treatment by both SPECT and DBS (p < 0.001 and p = 0.05, respectively) and by SPECT at the 12th month (p < 0.05). This was associated with hepatic encephalopathy improvement at 8 and 12 months (p = 0.008 and 0.004, respectively), which was not observed in the leucine group (p = 0.313 and 0.055, respectively). Isoleucine supplementation achieved a better impact on brain perfusion restoration in HE.

Abstract
Hepatic encephalopathy (HE) is a late complication of liver cirrhosis and is clearly associated with poor outcomes. Chronic liver insufficiency leads to progressive muscle wasting, impairing ammonia metabolism and thus increasing the risk for HE. Given the association between lean mass and adductor pollicis muscle thickness (APMT), it has been used to predict outcome and complications in many conditions, but not yet in cirrhotic patients. Therefore, this article aimed to study the association between HE manifestations and measures related to muscle mass and strength. This cross-sectional study included 54 cirrhotic outpatients with HE varying from subclinical to grade II according to the West-Haven criteria, who were submitted to neuropsychometric tests, electroencephalogram, brain Single Photon Emission Computed Tomography (SPECT), anthropometric measurements, handgrip strength (HGS) and dual energy X-ray absorptiometry exam (DXA). Multiple logistic regression analysis was performed to investigate the association between body composition measures and HE grade. Analysis of the area under the receiver operator characteristic (AUROC) curve revealed the values related to neurological manifestations (HE grades I and II). Reductions in APMT and HGS were associated with higher HE grades, suggesting a big impact caused by the loss of muscle mass and function on HE severity. The link between HE manifestations and anthropometric measures, namely APMT and HGS, point to a significant relation concerning skeletal muscles and the neurological impairment in this population.

Abstract
The aim of this study was to confirm the effectiveness of early physiotherapeutic stimulation for lymphatic flow progression in patients with breast cancer undergoing axillary dissection. This was a randomized experimental study on 22 patients who underwent lymphoscintigraphy in their arms on two different occasions, firstly without stimulation and secondly after randomization into two groups: without physiotherapeutic stimulation (WOPS; n=10) and with physiotherapeutic stimulation (WPS; n=12). The lymphoscintigraphy scan was performed with (99m)Tc-phytate administered into the second interdigital space of the hand, ipsilaterally to the dissected axilla, in three phases: dynamic, static, and delayed whole body imaging. Physiotherapeutic stimulation was carried out using Földi's technique. In both groups, images from the two examinations of each patient were compared. Flow progression was considered positive when, on the second examination, the radiopharmaceutical reached areas more distant from the injection site. Statistical analysis was used to evaluate frequencies, percentages and central trend measurements, and non-parametric tests were conducted. Descriptive analysis showed that the WPS and WOPS groups were similar in terms of mean age, weight, height, body mass index and number of lymph nodes removed. There were statistically significant associations between physiotherapeutic stimulation and radiopharmaceutical progression at all three phases of the study (p<0.0001). Early physiotherapeutic stimulation in breast cancer patients undergoing radical axillary dissection is effective, and can therefore be indicated as a preventive measure against lymphedema.

Abstract
Scintimammography using (99m)Tc-sestamibi is a noninvasive and painless diagnostic imaging method that is used to detect breast cancer when mammography is inconclusive. Because of the advantages of labeling with (99m)Tc-sestamibi and its high efficiency in detecting carcinomas, it is the most widespread agent for this purpose. Its accumulation in the tumor has multifactorial causes and does not depend on the presence of architectural distortion or local or diffuse density variation in the breast. The objective of this study was to evaluate the accuracy of scintimammography for detecting breast cancer. One hundred and fifty-seven patients presenting 158 palpable and non-palpable breast nodules were evaluated. Three patients were male and 154 were female, aged between 14 and 81 years. All patients underwent scintimammography, and the nodule was subjected to cytological or histological study, i.e., the gold standard for diagnosing cancer. One hundred and eleven malignant and 47 benign nodules were detected, with predominance of ductal carcinomas (n=94) and fibroadenoma/fibrocystic condition (n=11/n=11), respectively. The mean size was 3.11 cm (7-10 cm) among the malignant nodules and 2.07 cm among the benign nodules (0.5-10 cm). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy were 89, 89, 95, 78 and 89%, respectively. Analysis on the histological types showed that the technique was more effective on tumors that were more aggressive, such as ductal carcinoma. In this study, (99m)Tc-sestamibi scintimammography was shown to be an important tool for diagnosing breast cancer when mammography was inconclusive.
