Kinesiophobia and Associated Factors in Patients With Myocardial Infarction

Kinesiophobia is a well-known barrier to positive clinical outcomes among patients with various diseases, but there remain few comprehensive studies of kinesiophobia among patients with myocardial infarction (MI). In this cross-sectional study, we investigated the presence of kinesiophobia and its relationship with clinical outcomes among 42 patients with MI who completed the Tampa Scale of Kinesiophobia Swedish Version for Heart (TSK-SV Heart) the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Six-Minute Walk Test (6MWT), the Hospital Anxiety and Depression Scale (HADS), the modified Medical Research Council (mMRC) Dyspnea Scale, the Charlson Comorbidity Index (CCI), and the MacNew Heart Disease Health-Related Quality of Life Questionnaire. The participants' mean TSK-SV Heart score was 39.24 (SD = 6.65), and 71.4% of these patients reported a high level of kinesiophobia. The TSK-SV Heart score demonstrated a strong correlation with the IPAQ-SF, 6MWT walking distance, and mMRC score (p < .001), and a moderate correlation with the HADS, CCI, and MacNew Heart Disease HRQoL (p < .05). Patients with a high level of kinesiophobia had lower IPAQ-SF, 6MWT walking distance, and HRQoL and higher mMRC, CCI, and HADS scores than patients with low levels of kinesiophobia (p < .05). Kinesiophobia was common and represented a considerable risk factor for physical-psychosocial dysfunctions in these patients with MI. To maintain functional independence and to increase physical activity level, clinicians should consider kinesiophobia from early to late-stage disease and should add a treatment focus that seeks to eliminate kinesiophobia in cardiac rehabilitation programs.

Characterization of peripheral blood T follicular helper (TFH) cells in patients with type 1 Gaucher disease and carriers

BACKGROUND

Gaucher disease (GD) is the most common autosomal recessive lipid storage disease. In this study, the changes in TFH cells and IL-4 and IL-21 cytokines in blood samples of GD patients, carriers and healthy volunteers were investigated.

METHODS

Two pretreatment type 1 GD patients, 20 currently treated type 1 GD patients, 6 carriers, and 27 healthy volunteers were enrolled in the study. TFH cell (CD45RA^-CD4⁺CXCR5⁺) number, phenotype (PD1, ICOS expression), and cytokine production (IL-21, IL-4) were assessed via flow cytometric assays.

RESULTS

No significant differences were found between the groups with respect to the number, frequency and PD1 or ICOS expression of TFH cells between healthy controls, patients and carriers. However, IL-4⁺ TFH cells were significantly reduced both in percent and number in the treated GD patients compared with healthy controls (p < 0.05). Interestingly, the IL-21⁺ TFH cell number was increased in treated GD patients. When TFH cells were examined based on CXCR3 expression, the frequency of the PD1⁺Th17-Th2-like fraction (CXCR3^-) was found to be significantly increased in treated GD patients.

CONCLUSION

To our knowledge, this is the first study to assess TFH cells in GD patients, and to show that the production of IL-4 and IL-21 by TFH cells and their subsets may be altered in type 1 GD patients.

The Importance of DHEA-S Levels in Cushing's Syndrome; Is There a Cut-off Value in the Differential Diagnosis?

The purpose of this study was to determine possible cut-off levels of basal DHEA-S percentile rank in the differential diagnosis of patients with Cushing's syndrome (CS) with ACTH levels in the gray zone and normal DHEA-S levels. In this retrospective study including 623 pathologically confirmed CS, the DHEA-S percentile rank was calculated in 389 patients with DHEA-S levels within reference interval. The patients were classified as group 1 (n=265 Cushing's disease; CD), group 2 (n=104 adrenal CS) and group 3 (n=20 ectopic ACTH syndrome).ROC-curve analyses were used to calculate the optimal cut-off level of DHEA-S percentile rank in the reference interval in the differential diagnosis of CS, and the effectiveness of this cut-off level in the identification of the accurate etiology of CS was assessed in patients who were in gray zone according to their ACTH levels. The DHEA-S percentile rank in the reference interval were significantly lower in group 2 compared to the other two groups (p<0.001), while group 1 and group 3 had similar levels. The optimal cut-off level of DHEA-S percentile rank in the reference interval providing differential diagnosis between group 1 and group 2 was calculated as 19.5th percentile (80.8% sensitivity, 81.5% specificity) and the level demonstrated the accurate etiology in 100% of CD and 76% of adrenal CS patients who were in the gray zone. This study showed that the cut-off value of DHEA-S level less than 20% of the reference interval could be used for differential diagnosis of CD and adrenal CS with high sensitivity and specificity, and it should be taken into the initial evaluation.

New risk factors in determining long‑term mortality in patients undergoing TAVI: can the conventional risk scores be used as a long‑term mortality predictor?

BACKGROUND

Surgical risk in patients after transcatheter aortic valve implantation (TAVI) is determined by conventional scoring systems. However, these risk scores were developed to predict surgical mortality. Due to their insufficient predictive ability in patients after TAVI, novel risk scores are needed to predict long‑term mortality in this population.

AIMS

The study aimed to investigate the value of conventional risk scores in predicting long‑term mortality. Additionally, the impact of laboratory parameters on long‑term mortality was evaluated.

METHODS

Our study included 121 patients who underwent transfemoral TAVI.

RESULTS

The mean (SD) logistic European System for Cardiac Operative Risk Evaluation (EuroSCORE), EuroSCORE II, and the Society of Thoracic Surgeons (STS) risk score were 27.4 (9.7), 7.9 (4.6), and 4.6 (2.4), respectively. In‑hospital mortality rate was 1.7%. None of the risk scoring systems predicted in‑hospital mortality correctly. The STS score corresponded with the mortality rate of approximately 2 months, EuroSCORE II, with 6 months, and logistic EuroSCORE, with 30 months. Male gender (odds ratio [OR], 5.668; 95% CI, 1.055–30.446; P = 0.04) and low albumin levels before TAVI (OR, 0.109; 95% CI, 0.018–0.654; P = 0.02) were found to be the independent predictors of long‑term mortality.

CONCLUSIONS

Although all conventional risk scores overestimated in‑hospital mortality, the STS risk score predicted 2‑month, EuroSCORE II, 6‑month, and logistic EuroSCORE, 30‑month mortality. The independent predictors of long‑term mortality were male gender and low blood albumin levels before the TAVI procedure.

The role of baseline and post-procedural frontal plane QRS-T angles for cardiac risk assessment in patients with acute STEMI

BACKGROUND

To our knowledge, no study so far investigated the importance of post-procedural frontal QRS-T angle f(QRS-T) in ST segment elevation myocardial infarction (STEMI). The aim of our study was to investigate the role of baseline and post-procedural f(QRS-T) angles for determining high risk STEMI patients, and the success of reperfusion.

METHODS

A total of 248 patients with first acute STEMI that underwent primary percutaneous coronary intervention (pPCI) or thrombolytic therapy (TT) between 2013 and 2014 were included in this study. Baseline f(QRS-T) angle was defined as the angle which measured from the first ECG at the time of hospital admission. Post-procedural (QRS-T) angle was defined according to the treatment strategy as follows: the angle which measured from the post-PCI ECG in patients treated with pPCI; the angle which measured from the ECG taken 90 min after onset of therapy in patients treated with TT.

RESULTS

The baseline (101.9° ± 48.0 vs. 72.1° ± 49.1, p = 0.014) and post-procedural f(QRS-T) angles (95.7° ± 48.1 vs. 58.1° ± 47.1, p = 0.002) were significantly higher in patients who developed in-hospital mortality than the patients who did not develop in-hospital mortality. Also, f(QRS-T) angle measured at 90 min was significantly lower in patients with successful thrombolysis group compared to failed thrombolysis group (53.2° ± 42.8 vs. 77.3° ± 52.9, p = 0.033), whereas baseline f(QRS-T) angle was similar between two groups (78.6° ± 53.4 vs. 78.9° ± 54.0, p = 0.976). Multivariate analysis showed that post-procedural f(QRS-T) angle ≥89.6° (odds ratio: 3.541, 95% confidence interval: 1.235-10.154, p = 0.019), but not baseline f(QRS-T) angle, was independent predictor of in-hospital mortality.

CONCLUSION

f(QRS-T) angle may be used as a beneficial tool for determining high risk patients in acute STEMI. Unlike previous studies, we showed for the first time that that post-procedural f(QRS-T) can predict in-hospital mortality and TT failure.

Single Derivation Fragmented QRS Can Predict Poor Prognosis in Successfully Revascularized Acute STEMI Patients

Background

QRS fragmentation (fQRS) is classically defined as the presence of slurred QRS morphology in at least two contiguous leads, and its prognostic importance has been shown in ST elevation myocardial infarction (STEMI). However, no study has investigated the significance of single lead fQRS (sl-fQRS) in surface electrocardiography (ECG).

Objectives

To evaluate whether sl-fQRS is as valuable as classical fQRS in patients with acute STEMI who had successful revascularization with primary percutaneous coronary intervention (pPCI).

Methods

We included 330 patients with a first STEMI who had been successfully revascularized with pPCI. The patient’s electrocardiography was obtained in the first 48 hours, and the patients were divided into three groups according to the absence of fQRS (no-fQRS); fQRS presence in a single lead (sl-fQRS); and ≥2 leads with fQRS (classical fQRS).

Results

In-hospital mortality was significantly higher both in patients with sl-fQRS and in patients with ≥ 2 leads with fQRS compared to patients with no-fQRS. In ROC curve analysis, ≥ 1 leads with fQRS yielded a sensitivity of 75% and specificity of 57.4% for the prediction of in-hospital mortality. Multivariate analysis showed that sl-fQRS is an independent predictor of in-hospital mortality (OR: 3.989, 95% CI: 1.237-12.869, p = 0.021).

Conclusions

Although the concept of at least two derivations is mentioned for the classical definition of fQRS, our study showed that fQRS in only one lead is also associated with poor outcomes. Therefore, ≥1 leads with fQRS can be useful when describing the patients under high cardiac risk in acute STEMI.

The Relationship between neutrophil-to-lymphocyte ratio and fragmented QRS in acute STEMI patients treated with primary PCI

BACKGROUND

No study so far investigated fragmented QRS (fQRS) and neutrophil-to-lymphocyte ratio (NLR) together in ST segment elevation myocardial infarction (STEMI).

OBJECTIVE

To investigate the relationship between NLR and fQRS, and determine the prognostic significance of the combined use of these two parameters in STEMI.

METHODS

We included 368 patients with first acute STEMI who successfully revascularized with primary percutaneous coronary intervention.

RESULTS

Patients with fQRS had significantly higher NLR, and in-hospital mortality rate compared to patients with no-fQRS. The best cut-off value of NLR to predict mortality was 5.47. Patients with NLR≥5.47 had a higher frequency of fQRS and in-hospital mortality rate. Multivariate analysis showed that NLR was an independent predictor of the presence of fQRS (OR: 1.095, 95% CI: 1.039-1.153, P=0.001). When patients were stratified by fQRS and cut-off value of NLR, in-hospital mortality gradually increased (P<0.001).

CONCLUSION

NLR is independently associated with the presence of fQRS in STEMI patients. Combined use of both parameters provides additional prognostic contribution for identifying patients at higher cardiac risk.

Circulating levels of apoptotic markers and oxidative stress parameters in women with polycystic ovary syndrome: a case-controlled descriptive study

CONTEXT

Apoptotic dysregulation plays a role in the pathogenesis of polycystic ovary syndrome (PCOS).

OBJECTIVE

To evaluate circulatory apoptotic markers and oxidative stress in patients with PCOS.

MATERIALS AND METHODS

Forty-four women with PCOS, and 44 healthy women as controls were enrolled in the study. Oxidative stress parameters and caspases levels were measured in serum.

RESULTS

The caspase 9 level was significantly lower and related with oxidant status in patients with PCOS, while the circulating levels of caspases 3 and 7 were statistically similar in both groups.

DISCUSSION

This study is the first report demonstrating the circulating levels of apoptotic markers and their relationship with oxidant status in PCOS.

CONCLUSION

The circulating caspase 9 and oxidant status might contribute to apoptotic dysregulation in PCOS.

Is There any Association Between Celiac Disease and Helicobacter pylori?

Objective

It was aimed to determine if there was a correlation between celiac disease (CD) and Helicobacter pylori (H. pylori) by comparing the prevalence of H. pylori in patients with and without CD.

Materials and methods

The patients who were diagnosed with CD and tested for H. pylori and the patients who presented for gastroscopy and tested for H. pylori were evaluated retrospectively and the prevalence of H. pylori was compared.

Results

Fifteen (48%) of 31 patients who were diagnosed with CD and tested for H. pylori were males and had a mean age of 33.1 ± 12.7 years (17–72). In the CD group, H. pylori was positive in 15 patients (48%), and 592 antrum biopsy that was performed were included as the control group. Of these patients, 299 (50.5%) were males and had a mean age of 44.4 ± 17.05 years (16–96). Helicobacter pylori were positive in 316 patients (53.4%). Helicobacter pylori prevalence was similar in the groups with and without CD (p > 0.5).

Conclusion

Although the prevalence of H. pylori was lower in celiac patients compared to the control group, the difference was not statistically significant. Although no findings suggesting a correlation between CD and H. pylori was found, further studies should be conducted.

Impact of Everolimus and Low-Dose Cyclosporin on Cytomegalovirus Replication and Disease in Pediatric Renal Transplantation

In order to investigate the hypothesis that the mammalian target of rapamycin inhibitor everolimus (EVR) shows anticytomegalovirus (CMV) activity in pediatric patients, we analyzed the impact of EVR-based immunosuppressive therapy on CMV replication and disease in a large cohort (n = 301) of pediatric kidney allograft recipients. The EVR cohort (n = 59), who also received low-dose cyclosporin, was compared with a control cohort (n = 242), who was administered standard-dose cyclosporin or tacrolimus and an antimetabolite, mostly mycophenolate mofetil (91.7%). Multivariate analysis revealed an 83% lower risk of CMV replication in the EVR cohort than in the control cohort (p = 0.005). In CMV high-risk (donor+/recipient-) patients (n = 88), the EVR-based regimen was associated with a significantly lower rate of CMV disease (0% vs. 14.3%, p = 0.046) than the standard regimen. In patients who had received chemoprophylaxis with (val-)ganciclovir (n = 63), the CMV-free survival rates at 1 year and 3 years posttransplant (100%) were significantly (p = 0.015) higher in the EVR cohort (n = 15) than in the control cohort (n = 48; 1 year, 75.0%; 3 years, 63.3%). Our data suggest that in pediatric patients at high risk of CMV, an EVR-based immunosuppressive regimen is associated with a lower risk of CMV disease than a standard-dose calcineurin inhibitor-based regimen.

The Importance of the Number of Leads with fQRS for Predicting In-Hospital Mortality in Acute STEMI Patients Treated with Primary PCI

BACKGROUND

Fragmented QRS (fQRS) has been shown to be related to increased cardiovascular mortality and morbidity. However, limited data are available for evaluating the relationship between the number of leads with fQRS and in-hospital all-cause mortality in patients with acute ST segment elevation myocardial infarction (STEMI). The aim of our study is to investigate the prognostic importance of the number of leads with fQRS in acute STEMI patients treated by primary percutaneous coronary intervention (PCI).

METHODS

Two hundred ten eligible patients with acute STEMI that underwent primary PCI were enrolled in this study. Each patient's 12-lead electrocardiography (ECG) taken in the first 48 hours was analyzed and the number of leads with fQRS were recorded.

RESULTS

The number derivations with fQRS were significantly higher in patients who developed in-hospital mortality than the patients who did not develop in-hospital mortality (2.6 ± 2.6 vs 0.9 ± 1.3; P = 0.002). Also, patients with ≥3 leads with fQRS had higher rate of in-hospital all-cause mortality (23.5% vs 7.4%, P = 0.009), higher frequency of Q wave (67.6% vs 36.9%, P = 0.001), and higher frequency of fQRS with Q wave (67.6% vs 15.9%, P < 0.001) than those patients with <3 leads with fQRS. By a multivariate regression analysis, the number of leads with fQRS was found to be an independent predictor of in-hospital all-cause mortality (odds ratio: 1.415, 95% confidence interval: 1.049-1.909, P = 0.023).

CONCLUSIONS

The number of leads with fQRS on 12-lead ECG is an independent predictor of in-hospital all-cause mortality in patients with acute STEMI treated by primary PCI.

Heart rate turbulence analysis in female patients with fibromyalgia

OBJECTIVE

Fibromyalgia is characterized by diffuse musculoskeletal pain and discomfort. There are several reports regarding autonomic nervous system dysfunction in patients with fibromyalgia. Heart rate turbulence is expressed as ventriculophasic sinus arrhythmia and has been considered to reflect cardiac autonomic activity. Heart rate turbulence has been shown to be an independent and powerful predictor of sudden cardiac death in various cardiac abnormalities. The aim of this study is to determine whether heart rate turbulence is changed in female patients with fibromyalgia compared with healthy controls.

METHODS

Thirty-seven female patients (mean age, 40±11 years) with fibromyalgia, and 35 age- and sex-matched healthy female control subjects (mean age, 42±9 years) were included. Twenty-four hours of ambulatory electrocardiography recordings were collected for all subjects, and turbulence onset and turbulence slope values were automatically calculated.

RESULTS

The baseline clinical characteristics of the two groups were similar. There were no significant differences in turbulence onset and turbulence slope measures between patients and control subjects (turbulence onset: -1.648±1.568% vs. -1.582±1.436%, p ϝ 0.853; turbulence slope: 12.933±5.693 ms/RR vs. 13.639±2.505 ms/RR, p ϝ 0.508). Although body mass index was negatively correlated with turbulence slope (r ϝ -0.258, p ϝ 0.046), no significant correlation was found between body mass index and turbulence onset (r ϝ 0.228, p ϝ 0.054).

CONCLUSION

To the best of our knowledge, this is the first study to evaluate heart rate turbulence in patients with fibromyalgia. It appears that heart rate turbulence parameters reflecting cardiac autonomic activity are not changed in female patients with fibromyalgia.

The Predictive Value of Fragmented QRS and QRS Distortion for High-Risk Patients with STEMI and for the Reperfusion Success

BACKGROUND

QRS fragmentation (fQRS) and QRS distortion were separately shown to be related to increased cardiovascular mortality and morbidity. To our knowledge, no study so far evaluated both parameters together in ST segment elevation myocardial infarction (STEMI). The main goal of our study is to find out if fQRS and QRS distortion can help us to determine high-risk STEMI patients, and the success of reperfusion.

METHODS

Two hundred forty-eight eligible patients with acute STEMI that underwent coronary angiography consecutively between January 1, 2009, and July 1, 2011, were enrolled in this study. Twelve-lead electrocardiography (ECG) of the patients taken in the first 48 hours were analyzed. Patients with fQRS formed group 1, without fQRS formed group 2; with QRS distortion formed group 3, and without QRS distortion formed group 4.

RESULTS

Group 1 have lower left ventricular ejection fraction (LVEF; P < 0.001), higher maximum troponin levels (P < 0.001), lower ST segment resolution (P < 0.001), more frequent proximal lesions (P < 0.001) when compared to group 2. Similar findings were observed in group 3 in comparison to group 4. Group 1 had also more frequent three vessels disease (P < 0.001), and higher rates of failed thrombolysis (P < 0.001). In-hospital mortality was found to be higher in group 1 and group 3.

CONCLUSION

fQRS and QRS distortion may be useful for identifying patients at higher cardiac risk. fQRS can foresee thrombolytic therapy failure and three vessels disease whereas QRS distortion does not possess such quality. These findings may guide the physician deciding initial treatment modality in STEMI.

The relationship between red-cell distribution width and abnormal left ventricle geometric patterns in patients with untreated essential hypertension

Abnormal left ventricle (LV) geometric patterns are associated with an increased risk of vascular complications of hypertension (HT). The association between red-cell distribution width (RDW) and HT has been recently investigated; however, the relationship between abnormal LV geometric patterns and RDW has not been studied before. The aim of this study was to investigate the relationship between RDW and abnormal LV geometric patterns in patients with untreated essential HT. Measurements were obtained from 139 patients with untreated essential HT (mean age=51.3±16.3 years). Four different geometric patterns (NG, normal geometry; CR, concentric remodeling; EH, eccentric hypertrophy; CH, concentric hypertrophy) were determined according to the LV mass index (LVMI) and relative wall thickness (RWT). RDW, lipid parameters and other biochemical markers were measured in all patients. While the highest RDW values were detected in the CH group (P<0.05, for all), it was similar among the NG, CR and EH groups (P>0.05, for all). RDW was associated with age, LVMI and LV geometry in bivariate analysis (P<0.05, for all). In a receiver operating characteristic (ROC) curve analysis, a level of RDW>14.5 predicted CH with 81% sensitivity and 59% specificity. Age (beta=0.309, P=0.001), LV geometry type (beta=0.228, P=0.01) and RWT (beta=-0.278; P=0.25) were independent predictors of high RDW in multiple linear regression analysis. In conclusion, the highest RDW values were observed in the CH group in the untreated essential HT patients. RDW seems to be a useful tool for the prediction of end-organ damage in patients with untreated essential HT.

The assessment of cardiac autonomic functions in adolescents with a family history of premature atherosclerosis

OBJECTIVES

Subclinical atherosclerosis has been recently detected in adolescents with a family history of premature atherosclerosis. However, no studies in the literature have assessed the cardiac autonomic functions of these adolescents. The aim of this study was to evaluate the cardiac autonomic functions of adolescents with a family history of premature atherosclerosis compared with those of age- and gender-matched adolescents without a family history of atherosclerosis.

METHOD

We evaluated the cardiac autonomic functions of 36 adolescents with a family history of premature atherosclerosis (Group 1) and compared them with those of 31 age- and gender-matched adolescents whose parents did not have premature atherosclerosis (Group 2). Twenty-four-hour time domain (standard deviation of all normal sinus RR intervals [SDNN], standard deviation of the mean of normal RR intervals in each 5-minute segment [SDANN], root-mean-square differences in successive RR intervals) and frequency domain (very low frequency, low frequency, high frequency, low frequency/high frequency) parameters of heart rate variability were used for the evaluation of cardiac autonomic functions.

RESULTS

There were no differences in the time and frequency domain parameters of heart rate variability between the two groups. Heart rate was negatively correlated with SDNN (r=-0.278, p=0.035), while age was significantly correlated with root-mean-square differences in successive RR intervals, high frequency, low frequency and low frequency/high frequency (r=-0.264, -0.370, 0.265 and 0.374, respectively; p<0.05 for all).

CONCLUSION

We found that the cardiac autonomic functions of adolescents with a family history of premature atherosclerosis were not different compared with those of adolescents without a positive family history of premature atherosclerosis. It appears that subclinical atherosclerosis does not reach a critical value such that it can alter cardiac autonomic functions in adolescence.

Effect of radiotheraphy on impaired aortic elasticity and stiffness in patients with breast cancer

We evaluated the effect of radiotherapy (RT) on the elastic properties of the aorta using echocardiography in patients with breast cancer (BC). A total of 105 women with left-sided epidermal growth factor receptor 2 (erb-2) BC were divided into 2 groups, group 1 with patients who did not receive RT and group 2 with patients who received RT. In all patients, echocardiographic examination and serum high-sensitivity C-reactive protein (hs-CRP) levels were determined. A significant decrease in aortic distensibility (AD) and increase in hs-CRP were seen from group 1 to group 2. The AD was inversely correlated with left ventricle diastolic diameter, systolic blood pressure (SBP), left atrial diameter, age, and RT dose. The AD was significantly related to age, SBP, and RT dose. Increased RT dose is significantly correlated with impaired elastic properties that may contribute to the relation of RT and increased rate of cardiovascular events among patients with BC who received RT.

Heart rate variability and heart rate turbulence in hypothyroidism before and after treatment

BACKGROUND

Cardiac autonomic dysfunction may develop in patients with clinical or subclinical thyroid hormone deficiency. Heart rate variability (HRV) and heart rate turbulence (HRT) are used for evaluating changes in cardiac autonomic functions and also used to provide risk stratification in cardiac and noncardiac diseases. The aim of this study is to evaluate cardiac autonomic functions before and 6 months after thyroid replacement therapy in patients with thyroid hormone deficiency.

METHODS

Forty hypothyroid patients (mean age 48 ± 13, four male) and 31 healthy controls (mean age 51 ± 12, three male) were included in the study. Twenty-four hour ambulatory electrocardiogram recordings were taken using Pathfinder Software Version V8.255 (Reynolds Medical). The time domain parameters of HRV analysis were performed using the Heart Rate Variability Software (version 4.2.0, Norav Medical Ltd, Israel). HRT parameters, Turbulence Onset (TO), and Turbulence Slope (TS) were calculated with HRT! View Version 0.60-0.1 software.

RESULTS

HRV and HRT parameters were decreased in the patient group (SDNN; P < 0.001, SDANN; P < 0.009, RMSSD; P = 0.049, TO; P = 0.035, TS; P < 0.001). After 6 months of thyroid replacement therapy, there were no significant changes observed in either HRV or HRT.

CONCLUSIONS

Hypothyroidism may cause cardiac autonomic dysfunction. Treating hypothyroidism with L-thyroxine therapy does not effectively restore cardiac autonomic function. HRV and HRT can be used as to help monitor cardiovascular-related risk in this population.

Relation of adrenergic receptors, which have roles in gastroprotective and anti-inflammatory effect of adrenal gland hormones, with cyclooxygenase enzyme levels in rats

BACKGROUND AND AIMS

COX-2 enzyme inhibition is responsible for the anti-inflammatory effects of NSAIDs, COX-1 for their effects upon the gastrointestinal system (GIS), along with other side effects. We investigated the relationship between COX levels and those adrenergic receptors known to play a role in gastroprotection and anti-inflammatory activity.

METHOD

The effects of adrenaline and prednisolone on gastric COX-1 and COX-2 levels in both intact and adrenalectomized rats treated with doxazosin, yohimbine, propranolol, and metoprolol were determined.

RESULTS

We found that adrenaline increases COX-1 levels in the gastric tissue of both intact and adrenalectomized rats by stimulating alpha-2 receptors. Adrenaline decreases COX-2 levels by stimulating beta-2 adrenergic receptors. Prednisolone inhibits both COX-1 and COX-2 in the gastric tissue of intact rats. In adrenalectomized rats, prednisolone increases gastric COX-1 by stimulating alpha-2 receptors, and decreases COX-2 levels by stimulating beta-2 receptors.

CONCLUSION

Prednisolone cannot bind to a adrenergic receptors in the presence of adrenaline (intact rats) but, in its absence (adrenalectomy), binds to alpha-2 receptors, and stimulates them more effectively than adrenaline, suggesting a direct relationship between alpha-2 adrenergic receptors and COX-1 levels, whereas beta-2 receptors are directly related to COX-2 levels.

Papillon-lefevre syndrome with congenital hepatic fibrosis

Papillon Lefevre syndrome (PLS) is a rare autosomal recessive disorder, which is characterized by palmar-plantar hyperkeratosis, periodontitis, and premature loss of dentition. We report a 16 years old girl with PLS. The patient presented at 08 years of age with complaints of corn on the feet and hands, and failure to thrive. On examination, her upper primarily canines were loose, she had severe periodontitis, eruption of permanent teeth, diffuse eritematous and hyperkeratotic palms and soles that suggested the syndrome. During the follow-up, the patient was diagnosed to have congenital hepatic fibrosis (CHF) when she was 16 years old, while she was being investigated for the etiology of her splenomegaly and pancytopenia. We report a patient with PLS associated with CHF, an association that has not been previously described.

Serum levels of sL-selectin and tumour necrosis factor-alpha in children with type 1 diabetes mellitus

Type 1 diabetes mellitus (DM) is a result of inflammation and destruction of alpha-cells in the pancreatic islet cells. The aim of this study is to evaluate the associations of diabetes with soluble L-selectin (sL-selectin) and tumour necrosis factor-alpha (TNF-alpha) in children with type 1 DM; and also to evaluate the associations of these parameters with the disease period, glycaemic control state and puberty stage. Serum sL-selectin and TNF-alpha levels were measured in 44 children with type 1 DM and 44 healthy children. Neither the patients nor the control group showed significant difference between the levels of sL-selectin and TNF-alpha (sequence mean 12.17+/-1.62 ng/ml vs. 12.62+/-1.56 ng/ml and 7.27+/-3.1 pg/ml vs. 7.88+/-2.7 pg/ml). There was no statistically significant difference between children with duration of diabetes longer than 5 years and children with duration of diabetes shorter than 1 year. There was also no statistically significant difference between poor glycaemic control and good-acceptable glycaemic control patients. The present results indicate that sL-selectin and TNF-alpha serum levels are not increased and cannot be used as prognostic predictors in type 1 DM; and also sL-selectin and TNF-alpha do not change with the disease period, glycaemic control state and puberty stage.

Effects of type 2 diabetes mellitus on plasma fatty acid composition and cholesterol content of erythrocyte and leukocyte membranes

Insulin resistance is a major factor in the pathogenesis of type 2 diabetes mellitus (T2DM) and is related to the fatty acid profile of the plasma membranes. The purpose of the present study was to investigate fatty acid composition and cholesterol content of cell membranes in patients with type 2 diabetes and, thus, to evaluate the possible factors leading to the alteration of plasma membrane fluidity. The study was performed in 20 healthy control subjects and 32 patients with type 2 diabetes. The fatty acid profiles and cholesterol content of the erythrocyte (RBC) and leukocyte (WBC) membranes were determined by a gas chromatographic method. When one considers the membrane constituents increasing fluidity and the ones decreasing it, the diabetics had a membrane composition decreasing fluidity compared to controls. On the other hand, when compared to control subjects, type 2 diabetic patients showed a significantly higher proportion of C16:0 components in erythrocyte and leukocyte membranes and plasma samples (25.4+/-3.1% vs. 31.1+/-4%; 23.3+/-2.4% vs. 29.3+/-5.2%; 27.6+/-3.9% vs. 34.5+/-5.7%; p<0.005, p<0.01 and p<0.005, respectively). Our results suggest that the ratio of saturated:unsaturated fatty acids changes in plasma and cell membranes of patients with type 2 diabetes. This situation may cause, at least in part, RBC-WBC function abnormalities and insulin resistance because of inconvenient membrane fluidity.

Antioxidant enzyme activities and lipid peroxidation levels in erythrocytes of patients with oesophageal and gastric cancer

In this study, levels of lipid peroxidation and antioxidant enzyme activities were investigated in the erythrocytes of patients with oesophageal and gastric cancers. Erythrocytes were obtained from 17 patients with oesophageal cancer, 37 patients with gastric cancer and 20 healthy controls. Levels of malondialdehyde (MDA), a lipid peroxidation marker, and activities of copper- and zinc-containing superoxide dismutase (CuZn-SOD), catalase (CAT) and glutathione peroxidase (GPx) were determined using spectrophotometric methods. MDA levels and CuZn-SOD activity were significantly higher and GPx and CAT activities significantly lower in patients with oesophageal and gastric cancer than in controls. There were no statistically significant differences in the parameters measured in relation to disease stage in either patient group. These results indicate significant changes in the antioxidant defence system in patients with oesophageal and gastric cancer. It is postulated that this may lead to enhanced action of oxygen radicals, resulting in lipid peroxidation.

Intravenous pulse cyclophosphamide therapy in focal segmental glomerulosclerosis

AIMS

We herein report the results of intravenous pulse cyclophosphamide (IVCP) therapy of 5 patients with steroid-resistant focal segmental glomerulosclerosis (FSGS). All patients had been treated with oral and intravenous pulse methylprednisolone and failed to respond to steroids from onset and were considered as primary steroid-resistant. Before starting IVCP, all patients were also treated with other immunosuppressive drugs with or without steroids, but none of them responded to such therapies and no patient had any NPSH2 gene mutations.

METHODS

IVCP was given monthly at a dose of 500 mg/m2 for 6 months. At the end of 6 months, IVCP was discontinued in case there was no response. Otherwise, IVCP was continued for every 2 months. Oral prednisone was given concurrently at 60 mg/m2 daily for 6 weeks and then 40 mg/m2 on alternate days for 4 weeks. Prednisone was then tapered to 10 mg/m2 alternate days and continued during the therapy period.

RESULTS

Only 1 of these patients achieved remission after IVCP while 4 patients showed no response to IVCP. 2 patients who did not achieve remission progressed to end-stage renal disease (ESRD) and 2 others who had not been treated with cyclosporine before underwent cyclosporine therapy. None of our patients has suffered from adverse effects of IVCP.

CONCLUSION

We found that IVCP had a limited beneficial effect in treatment of steroid-resistant FSGS and it may be suggested that IVCP can be tried to treat steroid-resistant patients, also for patients with primary steroid resistance and those who do not respond to other immunosuppressive therapies.

A child with Beckwith-Wiedemann syndrome and posterior urethral valves

Beckwith-Wiedemann syndrome is a somatic overgrowth syndrome characterized by a variable incidence of congenital anomalies, including hemihypertrophy, omphalocele, macroglossia and renal malformations. We report a child with Beckwith-Wiedemann syndrome and posterior urethral valves. Urethral valve resection was successfully performed under general anesthesia after voiding cystourethrography. This is the first report of Beckwith-Wiedemann syndrome associated with posterior urethral valves.

Effectiveness of Hyperbaric Oxygen Therapy in the Treatment of Complex Regional Pain Syndrome

In this double-blind, randomized, placebo-controlled study we aimed to assess the effectiveness of hyperbaric oxygen (HBO) therapy for treating patients with complex regional pain syndrome (CRPS). Of the 71 patients, 37 were allocated to the HBO group and 34 to the control (normal air) group. Both groups received 15 therapy sessions in a hyperbaric chamber. Pain, oedema and range of motion (ROM) of the wrist were evaluated before treatment, after the 15th treatment session and on day 45. In the HBO group there was a significant decrease in pain and oedema and a significant increase in the ROM of the wrist. When we compared the two groups, the HBO group had significantly better results with the exception of wrist extension. In conclusion, HBO is an effective and well-tolerated method for decreasing pain and oedema and increasing the ROM in patients with CRPS.

A New Treatment Modality for Fibromyalgia Syndrome: Hyperbaric Oxygen Therapy

Fibromyalgia syndrome (FMS) is characterized by longstanding multifocal pain with generalized allodynia/hyperalgesia. There are several treatment methods but none has been specifically approved for this application. We conducted a randomized controlled study to evaluate the effect of hyperbaric oxygen (HBO) therapy in FMS (HBO group: n = 26; control group: n = 24). Tender points and pain threshold were assessed before, and after the first and fifteenth sessions of therapy. Pain was also scored on a visual analogue scale (VAS). There was a significant reduction in tender points and VAS scores and a significant increase in pain threshold of the HBO group after the first and fifteenth therapy sessions. There was also a significant difference between the HBO and control groups for all parameters except the VAS scores after the first session. We conclude that HBO therapy has an important role in managing FMS.

Traumatic spinal cord injuries in Turkey: a nation-wide epidemiological study

STUDY DESIGN

An epidemiological study conducted all over the country.

OBJECTIVE

The present retrospective study was conducted to survey the new traumatic spinal cord injury (SCI) cases during 1992 in Turkey.

SETTING

Intensive care units, emergency services and departments of orthopaedic surgery, neurosurgery and rehabilitation of state hospitals, rehabilitation centers, military and university hospitals.

METHODS

Postal questionnaires were used for data collection and the records from medical institutes nation-wide were reviewed for the analysis of the epidemiological factors.

RESULTS

Five hundred and eighty-one new traumatic SCI cases were reported in 1992. The annual incidence was found to be 12.7 per million population. Male to female ratio was 2.5:1 and the average age at injury was 35.5+/-15.1 (35.4+/-14.8 for males and 35.9+/-16.0 for females). The most common cause of injury was motor vehicle accidents (48.8%) followed by falls (36.5%), stab wounds (3.3%), gunshot injuries (1.9%) and injuries from diving (1.2%). One hundred and eighty-seven patients (32.18%) were tetraplegic and 394 patients (67.8%) were paraplegic. The most common level of injury was C5 among tetraplegics and T12 among paraplegics. The most prevalent associated injury was head trauma followed by extremity fractures. Severe head trauma resulting in death may obscure the real incidence of SCI and may cause underreporting of cases in epidemiological studies.

CONCLUSION

Considering that motor vehicle accidents and falls were found to be the leading causes of traumatic SCI, it was concluded that the prevention measures should be focused mainly on these in order to reduce the frequency of SCI in Turkey.

Peripheral nerve block with phenol to treat spasticity in spinal cord injured patients

In this study an attempt was made to treat spinal cord injured patients with severe spasticity by peripheral nerve blocks. Thirty-six patients (5 female, 31 male) ranging in age from 20 to 71 years (mean: 29 +/- 8.2) were treated by phenol injections. A specially designed electrostimulation needle was used for the injections. The results showed that peripheral nerve blocks with phenol solution could be a remedy on a temporary basis, but are not as effective as has been described previously.
