Effectiveness of kinesiologic taping on function and pain in patients with hemophilia A.

Background: Hemophilic arthropathy frequently results in musculoskeletal adjustments that impair functional capacity. Aim: We investigated the effects of kinesiologic taping on patients with hemophilic arthropathy in this study. Materials and Methods: Twenty-six patients were enrolled. Thirteen patients formed the Kinesiologic taping group (KT) and received the interventional protocol consisting of three kinesiologic taping sessions during three weeks; and 13 patients formed the control group (CG) and made three weeks of home exercises. All patients were evaluated using the Functional Independence Score in Hemophilia (FISH), Hemophilia Joint Health Score (HJHS), and Visual Analog Scale (VAS) at baseline, one week, and three weeks. Results: The mean scores for the VAS, HJSS, and FISH differed significantly before and after 3 weeks in both groups (P < 0.001). However, the differences in medians after the treatment were significantly greater in the KT group than in the CG group (P < 0.001). Conclusions: Kinesiologic taping was associated with physical improvement in hemophilia patients; however, also kinesiologic taping led to significant improvement in VAS scores.

Demographic and clinical characteristics of inpatient stroke patients in Turkey.

Objectives: This study aims to assess the stroke rehabilitation facilities provided by university hospitals (UHs) and training and research hospitals (TRHs) and to evaluate the geographical disparities in stroke rehabilitation. Patients and methods: Between April 2013 and April 2014 a total of 1,529 stroke patients (817 males, 712 females; mean age: 61.7±14.0 years; range, 12 to 91 years) who were admitted to the physical medicine and rehabilitation clinics in 20 tertiary care centers were retrospectively analyzed. Demographic, regional and clinical characteristics, details of rehabilitation period, functional status, and complications were collected. Results: The median duration of stroke was five (range, 1 to 360) months. The ratio of the patients treated in the TRH in the Marmara region was 77%, but only 25% of the patients were living in the Marmara region. Duration of hospitalization was longer in the TRHs with a median of 28 days compared to those of UHs (median: 22 days) (p<0.0001). More than half of the patients (55%) were rehabilitated in the Marmara region. Time after stroke was the highest in the Southeast region with a median of 12 (range, 1 to 230) months and the lowest in the Aegean region with a median of four (range, 1 to 84) months. Conclusion: This study provides an insight into the situation of stroke rehabilitation settings and characteristics of stroke patients in Turkey. A standard method of patient evaluation and a registry system may provide data about the efficacy of stroke rehabilitation and may help to focus on the problems that hinder a better outcome.

Taurine relaxes human radial artery through potassium channel opening action.

The vascular actions and mechanisms of taurine were investigated in the isolated human radial artery (RA). RA rings were suspended in isolated organ baths and tension was recorded isometrically. First, a precontraction was achieved by adding potassium chloride (KCl, 45 mM) or serotonin (5-hydroxytryptamine, 5-HT, 30 µM) to organ baths. When the precontractions were stable, taurine (20, 40, 80 mM) was added cumulatively. Antagonistic effect of taurine on calcium chloride (10 µM to 10 mM)-induced contractions was investigated. Taurine-induced relaxations were also tested in the presence of the K+ channel inhibitors tetraethylammonium (1 mM), glibenclamide (10 µM) and 4-aminopyridine (1 mM). Taurine did not affect the basal tone but inhibited the contraction induced by 5-HT and KCl. Calcium chloride-induced contractions were significantly inhibited in the presence of taurine (20, 40, 80 mM) (p<0.05). The relaxation to taurine was inhibited by tetraethylammonium (p<0.05). However, glibenclamide and 4-aminopyridine did not affect taurine-induced relaxations. Present experiments show that taurine inhibits 5-HT and KCl-induced contractions in RA, and suggest that large conductance Ca2+-activated K+ channels may be involved in taurine-induced relaxation of RA.

Netrin-1 is associated with macrophage infiltration and polarization in human epicardial adipose tissue in coronary artery disease.

BACKGROUND: Inflammatory activity originating from the epicardial adipose tissue (EAT) may have a role in coronary artery disease (CAD) pathogenesis. The relationship between macrophage infiltration, polarization in the EAT, and netrin-1 gene expression was investigated. METHODS: Macrophage infiltration and polarization were examined by immunohistochemical methods and expression levels of netrin-1, Unc5b, and cytokines related with M1-macrophage subtype (IL-12 and IL-18) were determined by quantitative polymerase chain reaction in subcutaneous and epicardial adipose tissue obtained from patients undergoing coronary artery bypass grafting and non-coronary cardiac surgery. RESULTS: CAD patients had higher CD68+ (p=0.005) and CD11c+ (p<0.001) macrophage count in EAT when compared to the controls. CD11c+/CD206+ macrophage ratio, which reflects dominancy of M1-macrophage phenotype, was significantly increased in EAT of CAD patients when compared to that of the controls (p=0.008). CAD patients had significantly higher netrin-1, Unc5b, and IL-18 gene expression in the EAT when compared to the control group (p<0.001, p<0.001, and p=0.006 respectively). Increased macrophage infiltration and polarization were associated with higher netrin-1, Unc5b, and IL-12 gene expression in EAT (p<0.05). CONCLUSIONS: Findings suggest a link between enhanced netrin-1 expression in EAT and macrophage infiltration and polarization in patients with CAD.

Effects of Balneotherapy and Physical Therapy on Sleep Quality in Patients with Osteoarthritis Aged 50 to 85 Years.

OBJECTIVES: This study aims to investigate the effect of balneotherapy (BT) and physical therapy (PT) on sleep quality in patients with knee osteoarthritis (OA) aged 50 to 85 years. PATIENTS AND METHODS: A total of 199 patients (76 males, 123 females; mean age 67.8±7.3 years; range 50 to 85 years) suffering from knee OA (Kellgren-Lawrence grade 2-3) for more than six months were enrolled. Sleep and functional status were assessed at baseline and after 19 sessions of BT and 15 sessions of PT by using Pittsburgh Sleep Quality Index and Western Ontario and McMaster Universities Osteoarthritis Index, respectively. RESULTS: A high prevalence of abnormal sleep quality in patients with knee OA was observed. The most common abnormality was sleep fragmentation (71%), with an increased sleep disturbance score. Patients reported significantly improved sleep, pain, stiffness, and functional status after BT and PT. CONCLUSION: Balneotherapy and PT improved self-reported sleep and functional status in patients with OA aged 50 to 85 years. We may conclude that BT and PT, which are used in the treatment of OA, not only reduce nocturnal pain, but also improve sleep quality.

Huge Intravascular Tumor Extending to the Heart: Leiomyomatosis.

Intravenous leiomyomatosis (IVL) is a rare neoplasm characterized by histologically benign-looking smooth muscle cell tumor mass, which is growing within the intrauterine and extrauterine venous system. In this report we aimed to present an unusual case of IVL, which is originating from iliac vein and extended throughout to right cardiac chambers. A 49-year-old female patient, who was treated with warfarin sodium due to right iliac vein thrombosis, was admitted to our department with intermittent dyspnea, palpitation, and dizziness. Physical examination was almost normal except bilateral pretibial edema. On magnetic resonance venography, there was an intravenous mass, which is originated from right internal iliac vein and extended into the inferior vena cava. Transthoracic echocardiography and transesophageal echocardiography revealed a huge mass extending from the inferior vena cava through the right atrium, with obvious venous occlusion. Thoracic, abdominal, and pelvic MR showed an intravascular mass, which is concordant with leiomyomatosis. Surgery was performed through median sternotomy. A huge mass with 25-cm length and 186-gr weight was excised through right atrial oblique incision, on beating heart with cardiopulmonary bypass. Histopathologic assessment was compatible with IVL. Exact strategy for the surgical treatment of IVL is still controversial. We used one-stage approach, with complete resection of a huge IVL extending from right atrium to right iliac vein. In such cases, high recurrence rate is a significant problem; therefore it should be kept in mind.

Oxaliplatin Induced Digital Ischemia and Necrosis.

Introduction. Digital ischemia is a rare complication of several chemotherapeutic medications. We aimed to present a patient with digital ischemia, secondary to a new generation chemotherapeutic drug, oxaliplatin. Case Report. 62-year-old woman presented to our department with severe pain, paresthesia, and distal acrocyanosis on her right hand fingertips. Her complaints started five days after the third cycle of a chemotherapy protocol consisting of 5-fluorourasil (5-FU), folinic acid, and oxaliplatin due to advanced colon carcinoma. On physical examination, hemorrhagic and partly ulcerative lesions were detected at her right hand fingertips. Radial and ulnar pulses were absent at affected side. Digital subtraction angiography revealed severe vascular resistance in the affected extremity. Iloprost trometamol treatment was started with the dosage of 1 ng/kg/min. In addition, low-molecule-weight heparin was used for preventing possible microemboli. Symptomatic relief was provided after five days, and patient was discharged on 7th day of treatment. Discussion. The pathogenesis of oxaliplatin induced vascular toxicity remains unclear. Endothelial damage, increased adherence of platelets, deposition of immune complexes as an immunologic effect of oxaliplatin, and hypercoagulable state may be the reason for arterial thrombosis, digital microemboli, possible digital ischemia, and their several consequences.

Preoperative frontal QRS-T angle is an independent correlate of hospital length of stay and predictor of haemodynamic support requirement following off-pump coronary artery bypass graft surgery.

OBJECTIVES: With the adoption of novel operative techniques and aggressive care protocols that facilitate earlier extubation and mobilization of patients, postoperative length of stay (LOS) following coronary artery bypass graft surgery (CABG) has declined. However, there is paucity of information regarding preoperative electrocardiographic predictors of LOS following CABG. In this study, we investigated whether frontal QRS-T angle, which is an abnormal repolarization marker in prediction of various cardiovascular events, was an independent correlate of postoperative hospital LOS for off-pump CABG. Furthermore, we evaluated independent predictors of vasopressor agent/intra-aortic balloon pump (IABP) support requirement following off-pump CABG. METHODS: In this observational study, 78 patients with stable angina, who were scheduled for elective coronary artery bypass surgery following diagnosis of obstructive coronary artery disease by conventional angiography, were enrolled. RESULTS: Left ventricular ejection fraction (LVEF) was significantly lower and vasopressor agent/IABP support requirement and incidence of sustained atrial or ventricular arrhythmias was higher in patients with wide QRS-T angle (P < 0.05). Postoperative hospital LOS was also longer in this group. From the preoperative characteristics, wide frontal QRS-T angle was found to be an independent correlate of postoperative hospital LOS (B ± SD: 11.97 ± 0.62, P ≤ 0.01). Wide frontal QRS-T angle was also found to be an independent predictor of vasopressor agent/IABP support requirement postoperatively (OR: 7.87, P ≤ 0.01). CONCLUSIONS: Prediction of the hospital LOS and patient outcome following CABG is of great importance. Being easily obtainable via standard 12-lead electrocardiogram and its low cost may make frontal QRS-T angle a beneficial marker for reducing both patient-based morbidity and economic burden.

How can follow-up of patients with Raynaud phenomenon be optimized?

BACKGROUND Raynaud phenomenon (RP) is common worldwide and presents diagnostic and therapeutic difficulties. We aimed to share our experience with optimizing of patient follow-up by using the cold-stimulation test (CST). MATERIAL AND METHODS Data of 81 patients admitted with RP symptomatology were collected. Demographic data and symptoms were recorded. A scale was used for determining the severity of disease at pre-treatment and post-treatment. CST was performed to all patients at pre-treatment and post-treatment for assessment of treatment efficiency in follow-up. Results were analyzed with the SPSS for Mac 20.0 program. RESULTS All the patients were male. Mean age was 22.3 ± 2.14 (19-29). Mean duration of symptoms from onset to present was 4.59 ± 2.85 years. There were statistically significant differences between pre-treatment and post-treatment hand temperatures measured by CST (p<0.001). However, there were no statistically significant differences between pre-treatment and post-treatment severity scores of patients (p=0.135). CONCLUSIONS To quantitatively determine the treatment efficacy, CST may be used instead of asking simple questions of patients.

Sodium nitrite provides angiogenic and proliferative effects in vivo and in vitro.

BACKGROUND Angiogenesis is the formation of new blood vessels from pre-existing vasculature. Many factors and substances may stimulate angiogenesis and exhibit proliferative effect. In this study, we aimed to investigate the angiogenic and proliferative effects of sodium nitrite. MATERIAL AND METHODS The angiogenic activity of sodium nitrite was examined in vivo in the chick chorioallantoic membrane (CAM) model and in vitro in tube formation assay of human umbilical vein endothelial cells (HUVECs). The proliferative activity of sodium nitrite was also determined through MTT assay on HUVECs. RESULTS In CAM assay, sodium nitrite had an angiogenic effect especially at high concentrations compared with the control group and this was statistically significant. There was a proliferative effect on HUVECs in the presence of sodium nitrite for 24 and 48 h, and this was statistically significant (p<0.05). Comparing the tube length/area ratio values, there was statistically significant increase in the sodium nitrite group compared to the control group (p<0.05). CONCLUSIONS The results provide evidence that sodium nitrite induces angiogenesis in vitro and in vivo.

Autonomic imbalance assessed by time-domain heart rate variability indices in primary Raynaud's phenomenon.

OBJECTIVES: The pathogenesis of primary Raynaud's phenomenon (RP) seems to be multifactorial and autonomic nervous dysfunction is one factor. Heart rate variability (HRV) is one of the most reliable parameters to demonstrate autonomic dysfunction. Our aim was to evaluate the time-domain HRV in patients with primary RP. METHODS: A time analysis of HRV was performed in patients with primary RP and age- and gender-matched healthy controls. The results of the study and control group were compared. RESULTS: Thirty patients with primary RP [all men, median (IQR) age: 21 (2) years) and 31 age- and gender-matched healthy controls (median (IQR): 21(3) years] were enrolled in the study. We found a statistically significant difference between the primary RP patients and control subjects in terms of time-domain HRV parameters (p < 0.05 for all). CONCLUSION: Our study showed the presence of autonomic nervous dysfunction of heart function in patients with primary RP.

Platelet indices may be correlated with severity of vasospastic disorders.

BACKGROUND Vasospastic disorders are common worldwide. In daily practice, routine blood samples are used for several investigations. In this study we aimed to determine the possible correlations between lymphocyte count, platelet indices, and the severity of vasospastic disorders. MATERIAL AND METHODS Data of 102 patients admitted to our department with vasospastic disorder symptomatology were retrospectively collected. Demographic data, symptoms, and blood test results were recorded. Patients were divided into 2 groups according to their rewarming time, which is determined by the cold stimulation test. Group 1 consisted of patients with rewarming time below 20 min and Group 2 consisted of patients with rewarming time above 21 min. Demographic data and blood test results were compared between groups. Results were analyzed with the SPSS for Mac 20.0 package program. RESULTS There was no statistically significant difference between the groups in demographic variables and symptomatology. In Group 2, mean platelet volume (MPV) and platelet distribution width (PDW) were higher than in Group 1, which was statistically significant (8.87 ± 0.74 vs. 8.38 ± 0.78, p=0.001 and 15.91 ± 1.92 vs. 14.7 ± 1.99, p=0.002, respectively). Similar to MPV and PDW, lymphocyte count was also higher in Group 2 than in Group 1 (2.28 ± 0.65 vs. 1.90 ± 0.68, p=0.002). CONCLUSIONS Diagnosis and grading the severity of VD is challenging, but it can be supported by the presence of increased PDW, MPV, and lymphocyte count.

Adding Doppler ultrasonography to the follow-up of patients with vasospastic disorder improves objectivity.

BACKGROUND: Assessing therapeutic efficacy and patient satisfaction objectively and quantitatively has always been a problem in patients with vasospastic disorders. We aimed to present the additive value of ultrasonographic assessment of peripheral arteries secondary to cold stimulation, as a test for treatment efficacy during follow-up. MATERIAL AND METHODS: Arterial blood flow rates were measured from radial artery with Doppler USG in patients who presented to our department with vasospastic disorders. Ultrasonography was performed at the following intervals; before cold stimulation and at 5th, 10th, 15th, 20th minutes of cold stimulation. Patients were controlled by repeat cold stimulation test and Doppler US at the 2nd month of the treatment. Results were analyzed with SPSS for Mac 20.0 package program. RESULTS: We enrolled 46 patients in the study. All patients were male and mean age was 22.3 ± 2.17 years. Most common symptoms were cyanosis and coldness. There were statistically significant differences between pre-treatment and post-treatment arterial blood flow rates at each measurement time point (p<0.001) except initial measurement (p>0.05). On post-treatment values, there were 10.04±0.78 cm/s increase in 5th minute, 6.25 ± 1.39 cm/s in 10th minute, 6.43 ± 2.13 cm/s in 15th minute, and 6.38 ± 1.86 cm/s in 20th minute measurements. All increases at the 5 time points were statistically meaningful when compared to their pre-treatment corresponding time points (p<0.001). CONCLUSIONS: Doppler flowmetry added to standard cold stimulation test for evaluating the patients with vasospastic disorders provides better and more objective results when compared to the patient-oriented subjective scoring systems.

Frontal planar QRS/T angle can be a prognostic factor in the early postoperative period of patients undergoing coronary bypass surgery.

BACKGROUND: Wide QRS/T angle reflects the ventricular repolarization heterogeneity and has been found in association with cardiac morbidity and mortality in various study populations. However, literature data about the availability of QRS/T angle in patients undergoing cardiac surgery has not yet been available. METHODS: A total of 157 patients who underwent isolated coronary artery bypass surgery were included in this study. A preoperative 12-lead ECG was obtained one day before surgical procedure. The absolute difference between the frontal QRS wave axes and T-wave axes was defined as frontal planar QRS/T angle. Afterwards, patients were divided into two groups according to their frontal planar QRS/T angle (the cut-off value as 90°). RESULTS: Group 1 consisted of 109 patients with frontal planar QRS/T angle of <90, and the remaining 48 patients with frontal planar QRS/T angle 90 were placed into group 2. Mean EuroSCORE was much higher in group 2. There were significant differences for positive inotropic agent usage (27.5% for group 1 versus 58.3% for group 2, P < .001) and the prevalence of postoperative atrial fibrillation (11.9% for group 1 versus 31.2% for group 2, P = .004) between the two groups. In multivariate logistic regression analysis, used to determine the independent predictors of positive inotropic usage in the early postoperative period, only frontal planar QRS/T angle (OR: 0.989, 95% CI: 0.981-0.997, P = .008) and EuroSCORE (OR: 0.792, 95% CI: 0.646-0.971, P = .025) were found to be statistically significant. CONCLUSION: We found that frontal planar QRS/T angle might be an important preoperative parameter in predicting the need for inotropic drugs in the early postoperative period following coronary artery bypass surgery.

Elasticity properties of pulmonary artery in patients with bicuspid aortic valve.

OBJECTIVE: Although the vascular complications of bicuspid aortic valve (BAV) disease cause significant morbidity and mortality, the role of pulmonary artery in this pathogenesis is less understood. We aimed to assess the elastic properties of pulmonary artery with echocardiography in patients with BAV. MATERIAL AND METHODS: Thirty patients with BAV (26 males) were enrolled in this study. The presence of aortic stenosis was accepted as exclusion criteria. Thirty-two healthy subjects (27 males) with no any history of cardiovascular disease comprised the control group. In all patients, maximal frequency shift (MFS) and acceleration time (AcT) of the pulmonary artery flow trace were measured echocardiographically in parasternal short-axis view. Subsequently, pulmonary artery stiffness (PAS) was calculated by using the following formula PAS (kHz/sec) = MFS/AcT. RESULTS: There were no significant differences in baseline demographic characteristics of the study population. Aortic strain and aortic distensibility index were lower, and aortic stiffness index (SI) higher, in patients with BAV. The PAS was significantly increased in patients with BAV compared with control subjects with tricuspid aortic valve (11.08 ± 2.27 vs. 7.11 ± 1.54, P < 0.001). There was a significant correlation between aortic diameters, aortic elasticity indexes, and PAS. Multivariate linear regression analysis, the only significant independent factor affecting the PAS was SI (ß = 0.547, P < 0.001). CONCLUSION: We demonstrated that elastic properties of pulmonary artery tend to be impaired as in the aorta in patients with BAV disease.

Comparison of results of autologous versus homologous blood transfusion in open-heart surgery.

BACKGROUND: The aim of this study was to determine a method to decrease the use of homologous blood during openheart surgery using a simple blood-conservation protocol. We removed autologous blood from the patient before bypass and used isovolumetric substitution. We present the results of this protocol on morbidity and mortality of surgery patients from two distinct time periods. METHODS: Patients from the two surgical phases were enrolled in this retrospective study in order to compare the outcomes using autologous or homologous blood in open-heart surgery. A total of 323 patients were included in the study. The autologous transfusion group (group 1) comprised 163 patients and the homologous transfusion group (group 2) 160 patients. In group 1, autologous bloods were prepared via a central venous catheter that was inserted into the right internal jugular vein in all patients, using the isovolumetric replacement technique. The primary outcome was postoperative In-hospital mortality and mortality at 30 days. Secondary outcomes included the length of stay in hospital and in intensive care unit (ICU), time for extubation, re-intubations, pulmonary infections, pneumothorax, pleural effusions, atrial fibrillation, other arrhythmias, renal disease, allergic reactions, mediastinitis and sternal dehiscence, need for inotropic support, and low cardiac-output syndrome (LCOS). RESULTS: The mean ages of patients in groups 1 and 2 were 64.2 ± 10.3 and 61.5 ± 11.6 years, respectively. Thirty-eight of the patients in group 1 and 30 in group 2 were female. There was no in-hospital or 30-day mortality in either group. The mean extubation time, and ICU and hospital stays were significantly shorter in group 1. Furthermore, postoperative drainage amounts were less in group 1. There were significantly fewer patients with postoperative pulmonary complications, pneumonia, atrial fibrillation and renal disease. The number of patients who needed postoperative inotropic support and those with low cardiac output was also significantly less in group 1. CONCLUSION: Autologous blood transfusion is a safe and effective method in carefully selected patients undergoing cardiac surgery. It not only prevents transfusion-related co-morbidities and complications but also enables early extubation time and shorter ICU and hospital stay. Furthermore, it reduces the cost of surgery.
