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.
Although the pathophysiology behind ATC cardiotoxicity is most likely multifactorial, myocardial sympathetic activity is not associated with a reduction in LVEF 5-years after completion of chemotherapy.
Goal: To evaluate the impact of iodine-131 therapy received during childhood and adolescence and correlate it with the quality of life in these patients. Methods: We studied 19 patients diagnosed with cancer in childhood or adolescence who underwent thyroidectomy and supplemental therapy with I-131. We also recruited a control group of healthy subjects with the same demographic parameters. All patients were subjected to a scintigraphy examination of the salivary glands, and were also asked to complete a questionnaire in order to assess their overall quality of life. In addition, a more specific questionnaire for patients with head and neck cancer was also given to all study participants. Results: The quantitative and qualitative analyses of the salivary glands showed functional deficits with greater involvement of the parotid gland for volume, concentration and excretion. The right submandibular gland showed significant changes for volume in the patient group. The questionnaires made it possible to observe significant differences between the patient and control groups for symptoms such as thick saliva, dry mouth and speech problems. Conclusion: In spite of being very effective and widely used, iodine radionuclide therapy * Corresponding author.

OBJECTIVES:The proper nodal staging of non-small cell lung cancer is important for choosing the best treatment modality. Although computed tomography remains the first-line imaging test for the primary staging of lung cancer, its limitations for mediastinum nodal staging are well known. The aim of this study is to evaluate the accuracy of hybrid single-photon emission computed tomography and computed tomography using 99mTc-sestamibi in the nodal staging of patients with non-small cell lung cancer and to identify potential candidates for surgical treatment.METHODS:Prospective data were collected for 41 patients from December 2006 to February 2009. The patients underwent chest computed tomography and single-photon emission computed tomography/computed tomography examinations with 99mTc-sestamibi within a 30-day time period before surgery. Single-photon emission computed tomography/computed tomography was considered positive when there was focal uptake of sestamibi in the mediastinum, and computed tomography scan when there was lymph nodes larger than 10 mm in short axis. The results of single-photon emission computed tomography and computed tomography were correlated with pathology findings after surgery.RESULTS:Single-photon emission computed tomography/computed tomography correctly identified six out of 19 cases involving hilar lymph nodes and one out of seven cases involving nodal metastases in the mediastinum. The sensitivity, specificity, positive predictive value, and negative predictive value for 99mTc-sestamibi single-photon emission computed tomography/computed tomography in the hilum assessment were 31.6%, 95.5%, 85.7%, and 61.8%, respectively. The same values for the mediastinum were 14.3%, 97.1%, 50%, and 84.6%, respectively. For the hilar and mediastinal lymph nodes, chest tomography showed sensitivity values of 47.4% and 57.1%, specificity values of 95.5% and 91.2%, positive predictive values of 90% and 57.1% and negative predictive values of 67.7% and 91.2%, respectively.CONCLUSION:Single-photon emission computed tomography/computed tomography with 99mTc-sestamibi showed very low sensitivity and accuracy for the nodal staging of patients with non-small cell lung cancer, despite its high level of specificity. In addition, the performance of single-photon emission computed tomography/computed tomography added no relevant information compared to computed tomography that would justify its use in the routine preoperative staging of non-small cell lung carcinoma.
Strength training resulted in a significant increase in cardiac dimensions. Both strength and endurance training seem to cause a reduction in myocardial sympathetic drive. However, myocardial morphological and functional adaptations to training were not correlated with myocardial sympathetic activity.
