Safety of non-standard regimen of systemic steroid therapy in patients with Graves' orbitopathy: a single-centre experience.

BACKGROUND: Graves' orbitopathy (GO) is an autoimmune disorder of the orbit and retro-ocular tissues and the primary extrathyroidal manifestation of Graves' disease. In moderate-to-severe and active GO iv glucocorticoids (GCs) are recommended as first-line treatment. The aim was to assess the safety profile of methylprednisolone administered intravenously for three consecutive days at 1 g in patients with active, moderate-to-severe or sight-threatening Graves' orbitopathy. METHODS: We retrospectively evaluated 161 medical records of patients with GO treated with high-dose systemic GCs in the Department of Endocrinology, Metabolic Disorders, and Internal Medicine in Poznan between 2014 and 2021. Clinical data included age, gender, laboratory results, activity and severity of GO, smoking status, disease duration, and presented side effects. RESULTS: The presence of mild side effects was observed during 114 (71%) hospitalizations. The most common complications were hyperglycemia (n = 95) and elevated aminotransferases (n = 31). Increased levels of aminotransferases were more likely observed in smokers and GO duration above 12 months. Based on the multivariate logistic regression, higher TRAb and CAS values were significantly associated with lower odds of hyperglycemia. In turn, the increased odds of elevated aminotransferases were significantly correlated with higher initial ALT levels, female gender, and GO duration above 12 months. In addition, the multidimensional correspondence analysis (MPA) showed that GO patients who declared smoking and had not L-ornithine L-aspartate applied demonstrated a higher probability of elevated aminotransferases. CONCLUSIONS: Active GO treatment with high-dose systemic GCs is not associated with serious side effects. Hyperglycemia is the most common steroid-induced complication.

Effect of dance movement therapy on balance in adults with Down Syndrome. A pilot study.

Systematic participation in dance therapy may improve balance and reduce risk of falls. The aim of this study was to assess the effect of dance therapy on balance and risk of falls in adults with Down syndrome. Study participants comprised 23 persons with Down syndrome aged 26- 49 years who underwent dance therapy. Before and after the therapy, all participants were measured on a BioSway balance platform using three tests: postural stability, limits of stability, and M-CTSIB fall risk. Mean result was lower following intervention (2.40 ± 1.81 vs. 1.65 ± 1.32; p = .006) in the postural stability test. The limits of stability test found a statistically significant difference (26.30 ± 8.99 vs. 37.90 ± 12.54; p < .001). The results of this study only partially supported the hypothesis that dance therapy improves balancing skills in adults with Down Syndrome.

The Influence of Self-Myofascial Release on Muscle Flexibility in Long-Distance Runners.

During long-distance running, athletes are exposed to repetitive loads. Myofascial structures are liable to long-term work, which may cause cumulating tension within them. The aim of this study was to evaluate the acute effect of self-myofascial release on muscle flexibility in long-distance runners. The study comprised 62 long-distance, recreationally running participants between the age of 20 and 45 years. The runners were randomly divided into two groups: Group 1 (n = 32), in which subjects applied the self-myofascial release technique between baseline and the second measurement of muscle flexibility, and Group 2 (n = 30), without any intervention. The self-myofascial release technique was performed according to standardized foam rolling. Assessment of muscle flexibility was conducted according to Chaitow's proposal. After application of the self-myofascial release technique, higher values were noted for the measurements of the following muscles: piriformis, tensor fasciae latae muscles and adductor muscles. Within the iliopsoas and rectus femoris muscles, lower values were observed in the second measurement. These changes were statistically significant (p < 0.05) within the majority of muscles. All these outcomes indicate improvement related to larger muscle flexibility and also, an increase in range of motion. In the control group (Group 2), significant improvement was observed only in measurements for the iliopsoas muscles. The single application of self-myofascial release techniques with foam rollers may significantly improve muscle flexibility in long-distance runners. Based on these results, the authors recommend the self-myofascial release technique with foam rollers be incorporated in the daily training routine of long-distance runners, as well as athletes of other sport disciplines.

Influence of Nordic Walking Training on Vitamin D Level in the Blood and Quality of Life among Women Aged 65-74.

INTRODUCTION: Demographic forecasts indicate the progressive aging process of societies in all countries worldwide. The extension of life span may be accompanied by deterioration of its quality resulting from a decrease in physical activity, mental or even social performance, and a deficit in certain chemical compounds responsible for proper functioning of the body. AIM: The aim of the study was to evaluate the influence of a 12-week Nordic walking (NW) training intervention on the level of vitamin D in the blood and quality of life among women aged 65-74 years. MATERIALS AND METHODS: The study comprised 37 women aged 65-74 (x = 68.08, SD = 4.2). The subjects were randomly assigned to 2 groups: experimental group (NW), which consisted of 20 women who underwent an intervention in the form of Nordic walking training for 12 weeks, and the control group (C), including 17 women who underwent observation. In the experimental group, training sessions were held 3 times a week for 1 h. At that time, the C group was not subject to any intervention. The SF-36 questionnaire was used to measure quality of life. Vitamin D was assessed based on the results of biochemical blood tests. The analysed parameters were assessed twice-before and after the completed intervention or observation. RESULTS: Comparison of the results regarding trials 1 and 2 allowed to note statistically significant improvement in quality of life for all health components and factors in the NW group. Analysis of vitamin D levels demonstrated a statistically significant increase in the NW group. In group C, no significant changes in the analysed parameters were observed. CONCLUSIONS: Regularly undertaking Nordic walking training significantly influences the improvement of self-evaluation regarding the components of physical and mental health, as well as the concentration of vitamin D in women aged 65-74 years.

Assessment of Measurement Reliability for the IPN Test in Cardiac Patients.

Cardiological diagnostics use maximal and submaximal tests with increasing load. Maximal stress tests are currently considered the gold standard. The Institut für Prävention und Nachsorge, Cologne (IPN) test may be an alternative when maximal patient load is not indicated. The universality of the test is well-documented in sport, but the reliability of this test is unknown. The aim of this study was to assess between-trial and between-day reliability for parameters assessed by the IPN stress test in cardiological patients.: In a study of 24 patients aged 39 to 79 years with cardiovascular diseases, the IPN cycle ergometer short test was performed (submaximal performance test). The reliability of heart rate, systolic and diastolic pressure, absolute power at submaximal load, relative performance at submaximal load and target heart rate were assessed. Good (Interclass Correlation Coefficient (ICC) values ranged from 0.832 to 0.894) and excellent (ICC values ranged from 0.904 to 0.969) between-trial reliability was noted. Between-day reliability was good (ICC values from 0.777 to 0.895) and excellent (ICC values from 0.922 to 0.950). The obtained results suggest that the IPN test may be a reliable tool for use in the assessment of cardiological patients, avoiding the implementation of maximal efforts when excessive patient load is not recommended.

Evaluation of the Effectiveness of Nordic Walking Training in Improving the Gait of Persons with Down Syndrome.

People with Down syndrome (DS) show dysfunction of gait, expressed by disturbed character of angular changes and values of the spatiotemporal parameters as compared to the physiological norm. It is known that exercises and various activities have positive effect on balance and gait, but there are only a few scientific proofs concerning above-mentioned in people with DS. Furthermore, the effect of Nordic Walking (NW) training on gait in people with DS is unexplored. We enrolled 22 subjects with DS, aged 25-40 years, with moderate intellectual disability. Participants were randomly divided into 2 groups: NW training group which underwent 10 weeks of training at a frequency of 3 times a week and control group with no specific intervention. Subjects were examined twice: 1 week before training and a week immediately after intervention. Gait was evaluated by the Vicon 250: a computerized system of three-dimensional analysis of motion, connected to 5 infrared video cameras. We conducted mixed-design ANOVA model to assess the effects of time and type of training on spatiotemporal parameters. We found significant favorable time by group interaction in the following parameters: step length in right leg: F(1,15) =14,47, p=0.002; left leg accordingly F(1,15) =5,15, p=0.038, cycle length in right leg: F(1,15) =14,48, p=0.002; left leg accordingly F(1,15) =15,09, p=0.001; and gait standardised speed F(1,15) =5,35, p=0.035. Statistically significant changes were observed in numerous kinematic parameters of ankle, knee, pelvis, and shoulder in NW group. Regular NW training has positive influence on selected spatiotemporal and kinematic parameters in people with Down Syndrome and may be an attractive and safe form of rehabilitation.

The occurrence of thyroid focal lesions and a need for fine needle aspiration biopsy in patients with acromegaly due to an increased risk of thyroid cancer.

OBJECTIVE: The high prevalence of goiter in acromegalic patients is well known. Several studies revealed increased frequency of thyroid carcinoma in these patients. The aim of the study was to evaluate the incidence of thyroid lesions, including thyroid cancer in acromegalic patients and to estimate possible factors influencing their occurrence, especially high IGF-1 level. MATERIALS AND METHODS: 86 consecutive patients with acromegaly were retrospectively analyzed. 45 patients had been previously treated for acromegaly and 41 were newly diagnosed. In all subjects hGH, IGF-1, TSH, FT4 levels were determined. Thyroid gland was evaluated in ultrasound examination. Fine needle aspiration biopsy (FNAB) was performed in every solid or mixed thyroid nodule. RESULTS: Thyroid morphology abnormalities were found in 75 patients (87.2%). 10 patients (11.6%) had diffuse goiter and 65 patients (75.6%) had nodular goiter. There were 5 cases of thyroid carcinoma (5.8%): 3 papillary carcinomas and two follicular variants of papillary cancer. Out of five cancers three were multifocal, one infiltrated thyroid capsule and one was diagnosed at the stage of metastases to four lymph nodes. CONCLUSIONS: Our study confirmed common co-existence of acromegaly and thyroid lesions. Furthermore, it revealed considerably high occurrence of thyroid carcinoma in these patients. In view of this correlation, the potential role of IGF-1 in pathogenesis of benign and malignant thyroid neoplasms should be considered. Due to high frequency of thyroid cancer in acromegalic patients, we suggest to perform fine needle aspiration biopsy in each case of thyroid nodule.

Graves' hyperthyroidism following primary hypothyroidism due to Hashimoto's thyroiditis in a case of thyroid hemiagenesis: case report.

Thyroid hemiagenesis (TH) is a rare inborn anomaly, resulting from failure of one thyroid lobe development. It is usually detected incidentally during investigation of concomitant thyroid disorders. The reported patient first presented hypothyroidism at the age of 49, when Hashimoto's thyroiditis (HT) and left thyroid lobe agenesis was diagnosed. L-thyroxine (LT4) replacement therapy restored hormonal balance. Two years later, the patient developed features of Graves' hyperthyroidism. The antithyroid pharmacotherapy by thiamazole was used. However, due to severe side-effects it was discontinued, and radioiodine treatment was applied. Four months after 131I administration, symptoms of hypothyroidism appeared, so thyroid hormone substitution was reintroduced. The patient, whose observation period has now reached 5 years, under LT4 replacement therapy, remains both clinically and biochemically euthyroid. The described case displays a very rare coincidence of hypothyroidism due to HT converted into Graves' hyperthyroidism, accompanying TH. Each of these three entities, may influence the thyroid function in a different way, hence, systematic follow-up and individual therapeutic management is required.

The prevalence of autoantibodies to: myosin, troponin, tropomyosin and myoglobin in patients with circulating triiodothyronine and thyroxine autoantibodies (THAA).

OBJECTIVE: Anti-thyroglobulin, anti-thyroid-peroxidase and anti-TSH receptor antibodies have been observed with high frequency in autoimmune thyroid diseases. Thyroid hormone auto-antibodies (THAA): anti-thyroxine (T4) and anti-triiodothyronine (T3), conversely, have been reported rarely. In both hyperthyroidism and hypothyroidism, patients suffer from muscle weakness and function disorders. The aim of our study was the evaluation of the occurrence rate of autoantibodies targeting muscle proteins in a group of 24 patients with circulating anti-T3 and/or anti-T4 autoantibodies. The control group consisted of 41 healthy blood donors. METHODS: In polyethylene tubes coated with muscle antigens: actin, myosin, myoglobin, troponin and tropomyosin solid-phase radioimmunoassay was performed to detect autoantibodies. A reaction with 125I-labelled staphylococcus protein A was used for the detection of antibodies bound to the antigens on the tubes. RESULTS: We found a high occurrence of antibodies to muscle proteins in patients with THAA. Anti-myoglobin autoantibodies were most frequent (54.2% of subjects), the binding index values was very high and exceeded normal values two to four fold. Anti-myosin autoantibodies were detected in 50% of subjects; anti-troponin autoantibodies in 33.3%, and anti-tropomyosin autoantibody in 3 patients (12.5%). Differences between the patients and the controls were statistically significant. The antibody binding index to actin was low and statistically insignificant. CONCLUSIONS: Our study indicates that muscle protein antibodies, especially to myoglobin, myosin and troponin, are very frequently present in patients with autoimmune thyroid disease and circulating anti-T3 and anti-T4 autoantibodies, as well as in most cases of chronic thyroiditis with clinical symptoms of hypothyroidisms.

Radioiodine treatment of hyperthyroidism in patients with low thyroid uptake.

BACKGROUND: The aim of the study was to analyze the effectiveness of radioactive 131I in hyperthyroid patients with confirmed lowered iodine uptake as compared to patients with an uptake of over 30%. MATERIAL AND METHODS: We retrospectively analyzed 53 consecutive patients aged from 29 to 84 (mean age 60 years) suffering from hyperthyroidism caused by Graves' disease or toxic nodular goitre. The patients were divided into 2 sub-groups: the 1st with a maximum iodine uptake of 18.7 +/- 3.2% (range, 11-23%) - 24 patients; the 2nd with a maximum iodine uptake of 27.1 +/- 2.1% (range, 24-30%) - 29 patients. The control group consisted of 50 patients treated with 131I with an iodine uptake of over 30%. Each patient was evaluated before, and 6 months after, treatment for fT3, fT4 and TSH with ECLIA; TRAb with RIA; ultrasound with a 7.5 MHz linear probe. The volume of the thyroid gland was determined using the Gutekunst method. All these factors underwent statistical analysis and were considered along with the results of clinical examinations. RESULTS: Clinical remission of hyperthyroidism was evident in 79.3% of both sub-groups, in total (83.3% and 75.3%, respectively). TSH was normalized in 62.3% of these patients (54.2% and 69.0%, respectively). The mean range of TSH levels increased from 0.081 microU/ml to 4.0 microU/ml after therapy; that is, from 0.087 microU/ml to 4.97 microU/ml in the 1st sub-group and from 0.076 microU/ml to 3.3 microU/ml in the 2nd sub-group. The volume of the thyroid gland was uniformly significantly lower, with a mean range of 40.5 ml before treatment and 21.7 ml afterwards. The results seen in both sub-groups were similar; only age and dose of radioiodine were slightly higher in the 1st, while mean uptake was higher in the 2nd. By comparison of these results to those of the control patients, we observed that the values of TSH, as well as thyroid volume and evidence of clinical remission, reflected those found in the control group. The mean dose of 131I was lower in the control group, that is 11.3 m Ci, as compared to the sub-groups as a whole, specifically, 15.7 mCi. The mean age of patients in the control group was slightly less than that of the study group (50.8 and 60, respectively). CONCLUSIONS: 1. The results of the treatment of patients with a low iodine uptake are similar to the results obtained in the group of patients with iodine uptake above 30% and therefore low iodine uptake should not be a contraindication for isotope I-131 therapy. 2. Additionally, we have demonstrated that a statistically significant decrease in thyroid volume is observed in all patients after the iodine isotope treatment which indirectly proves the effectiveness of the prescribed treatment, and that low thyroid iodine uptake is more frequently observed in elderly patients and in patients treated with iodine or anti-thyroid drugs.
