A comparative perspective on brucellar, pyogenic, and tuberculous spondylodiscitis

OBJECTIVE

Non-specific features of spondylodiscitis lead to a delay and challenge in the diagnosis/differential diagnosis/treatment processes, and thus, serious complications may arise. This study aims to compare brucellar, pyogenic, and tuberculous types of spondylodiscitis, considering their demographic, clinical, and laboratory differences. This may provide more rapid management and good outcomes.

PATIENTS AND METHODS

A total of 131 patients with infectious spondylodiscitis were included in the study. The patients were divided into brucellar (n=63), pyogenic (n=53), and tuberculous (n=15) types of spondylodiscitis and compared for demographic, clinical, laboratory, and imaging features.

RESULTS

Tuberculous spondylodiscitis had higher scores for weight loss, painless palpation, thoracic spine involvement, and psoas abscess formation than other spondylodiscitis. Also, tuberculous spondylodiscitis had higher rates of neurologic deficit and lower rates of lumbar involvement than brucellar spondylodiscitis. Pyogenic spondylodiscitis is more likely to occur in patients who have a history of spine surgery compared to other forms of spondylodiscitis. Also, pyogenic spondylodiscitis had higher rates of fever, erythema, paraspinal abscess, white blood cell (WBC), and erythrocyte sedimentation rate (ESR) than brucellar spondylodiscitis. On the other hand, brucellar spondylodiscitis had higher rates of rural living and sweating than pyogenic spondylodiscitis.

CONCLUSIONS

Weight loss, painless palpation, involved thoracic spine, psoas abscess, and neurologic deficit are symptoms favoring tuberculous spondylodiscitis. History of spine surgery, high fever, skin erythema, and paraspinal abscess are findings in favor of pyogenic spondylodiscitis. Rural living, sweating, and involved lumbar spine are symptoms that indicate brucellar spondylodiscitis. These symptoms can be used to distinguish the types of spondylodiscitis.

Spiritual Well-being, Diabetes Burden, Self-management, and Glycemic Control Among Patients with Type 2 Diabetes in Turkey: A Descriptive and Correlational Study

Spiritual well-being is considered a significant factor in helping to manage chronic diseases and cope with the disease process. This descriptive-correlational study aimed to investigate the relationship between spiritual well-being, diabetes burden, self-management, and among 300 outpatients with type 2 diabetes in Turkey. A significant relationship was found between the diabetes burden and self-management levels and the spiritual well-being of patients with diabetes (p < 0.005). Multiple linear regression analyses found that a high diabetes burden (ß = -0.106) decreased well-being, and high self-management increased well-being (ß = 0.415). Additionally, the results revealed that marital status, household members, performing daily life activities alone, hospitalization due to complications, diabetes burden, self-management, glycemic control, and blood lipid parameters explained 29% of the total variance in the spiritual well-being level. Accordingly, the present study recommended that health professionals should consider spiritual well-being to support disease management with a holistic approach to diabetes patients.

The role of metabolic diseases in neonatal convulsions

OBJECTIVE

The neonatal period is the most vulnerable time for the development of seizures, particularly in the first weeks after birth. These seizures often signify serious malfunction or damage to the immature brain and constitute a neurological emergency, necessitating urgent diagnosis and management. This study was performed to identify the etiology of convulsions during the neonatal period and to determine the rate of congenital metabolic disease.

PATIENTS AND METHODS

A total of 107 term and preterm infants 0-28 days old who were treated and followed-up in the neonatal intensive care unit of our hospital between January 2014 and December 2019 were analyzed retrospectively based on data obtained by scanning the hospital information system and patient files.

RESULTS

The study population included 54.2% male infants, and 35.5% of infants were born by caesarean section. Birth weight was 3,016 ± 560 (1,300-4,250) g, mean length of gestation was 38 (29-41) weeks, and mean maternal age was 27.4 ± 6.1 (16-42) years. Of the infants, 26 (24.3%) were preterm and 81 (75.7%) were term deliveries. Examination of family history revealed 21 (19.6%) cases with consanguineous parents and 14 (13.1%) cases with a family history of epilepsy. Hypoxic ischemic encephalopathy was the most common etiology of the seizures (34.5%). Burst suppression was detected on amplitude integrated electroencephalography in 21 (56.7%) monitored cases. Although subtle convulsions were most common, myoclonic, clonic, tonic and unclassified convulsions were also observed. The convulsions appeared during the first week of life in 66.3% of cases and during the second week or later in 33.7%. Fourteen (13.1%) patients examined by metabolic screening due to suspected congenital metabolic disease had a different congenital metabolic diagnosis.

CONCLUSIONS

Although hypoxic ischemic encephalopathy was the most common cause of neonatal convulsions in our study, congenital metabolic diseases with autosomal recessive inheritance were detected at a high rate.

Therapeutic plasma exchange in hyperthyroidism prior to surgery

PURPOSE

Therapeutic plasma exchange (TPE) is a treatment option to reduce thyroid hormones in the event of contraindication or unresponsiveness to antithyroid drugs (ATDs).

METHODS

We analyzed 11 patients with hyperthyroidism who received TPE prior to surgery between January 2008 and December 2016 at our center.

RESULTS

In total, 41 processes were applied to 11 patients with hyperthyroidism. The median age was 40 years, and 90.9% of the patients were female. Seven patients had Graves' disease, while four had a toxic multinodular goiter. The distribution of TPE indications comprised contraindication to ATDs (64%) and insufficient response to ATDs (36%). An adequate response was not obtained with TPE in two patients, and cholestyramine plus methimazole and Lugol solution were applied. The median number of TPE sessions was 3. During the TPE period, a β-blocker was applied concurrently except in one patient who was contraindicated for the drug. The reduction in FT3 and FT4 hormones and the increase in TSH levels were statistically significant after TPE application (p values of 0.003, 0.033 and 0.008, respectively). Regarding adverse events of TPE application, an allergic reaction was seen in one patient, while prolongation of prothrombin time without any clinical findings was seen in another patient. Ten patients underwent total thyroidectomy, and one patient underwent a gynecological surgery procedure without any major complications.

CONCLUSION

The American Society for Apheresis guideline, which is the most referenced guideline, mentions the utilization of TPE before thyroid surgery, only in patients with thyrotoxicosis despite the wider necessity of this treatment choice under the condition of uncontrolled hyperthyroidism prior to any kind of surgery. We concluded that TPE is a reliable and effective application in patients with hyperthyroidism before any surgical procedure, according to our study results.

The frontal planar QRS/T angle in patients with non-ischemic type late gadolinium enhancement on cardiac magnetic resonance

OBJECTIVE

Evaluation of myocardial fibrosis may offer an insight into underlying pathological mechanisms of ventricular arrhythmias. We intended to investigate the possible association between the presence and extent of myocardial fibrosis and ventricular repolarization heterogeneity based on frontal planar QRS/T angle.

PATIENTS AND METHODS

We retrospectively investigated patients in whom gadolinium-based contrast agent cardiac magnetic resonance imaging was performed due to the suspicion of any myocardial disease. Patients with non-ischemic type late gadolinium enhancement (LGE) were enrolled into this study. The association between presence and extent of myocardial LGE and frontal planar QRS/T angle defined as the absolute difference between QRS wave axis and T-wave axis on a resting 12-lead surface ECG was evaluated.

RESULTS

The frontal planar QRS/T angle was significantly higher in patients with myocardial fibrosis indicated by LGE compared to those without LGE (61.67 ± 40.70 vs. 37.27 ± 32.35, p < 0.001). LGE extent score assessed by visual 17-segment model was the only independent variable, which had a significant effect on frontal planar QRS/T angle [Unstandardized Coefficients B = 4.052, 95% CI [(2.025) - (6.079), p < 0.001].

CONCLUSIONS

In conclusion, this study showed that inhomogeneous areas of myocardium due to varying degrees of myocardial fibrosis might affect the electrical activity of the left ventricle, even with normal left ventricular dimensions and function.

Depression and Religious Coping in Patients with Acute Coronary Syndrome in Turkey

Psychological health problems such as depression, anxiety and feelings of distress are often seen in patients with acute coronary syndrome (ACS). Religious coping in dealing with psychological health problems is one of the methods commonly used by cardiac patients. This study was conducted to determine the depression levels and religious coping methods of individuals diagnosed with ACS and identify the relationship between their positive or negative religious coping methods and their depression levels. The descriptive and correlational study was conducted with 253 ACS patients. In the study, the depression levels of most patients were low, but 19.8% showed moderate-severe depressive symptoms. It was found that the patients adopted positive religious coping styles on a high level, but there was no significant relationship between positive religious coping and depression levels (p > 0.05). It is recommended that health professionals also closely monitor ACS patients for depressive symptoms after their diagnosis, encouraging patients to use positive religious coping styles to support their well-being and recovery against this life-threatening disease.

Pre-dilatation prior to carotid artery stenting in very severe carotid artery stenosis: beneficial or detrimental?

Background

There are many technical variations in carotid artery stenting and there is not a clear recommendation in pre-dilatation (Pre-D) prior to stenting. In this study we investigated the role of Pre-D before carotid artery stenting in patients with very severe carotid artery stenosis (≥90%).

Methods

A total of 298 patients with a carotid stenosis equal to or more than 90% were included to our study. Patients were divided into two groups as Pre-D and No-Pre-D. In-hospital and 3-year long-term clinical outcomes were compared between the groups.

Results

During the hospitalization, major stroke was more common in Pre-D group [n=6 (5.5%) vs. n=3 (1.5%), respectively], whereas overall ipsilateral stroke rates were similar between the groups. The rates of myocardial infarction were similar between the groups. In- hospital mortality was significantly higher in the Pre-D group than non-pre-D group [n=4 (3.6%) vs. n=0 (0%), respectively]. During the 3-year follow up period, the rates of ipsilateral stroke, major stroke, transient ischemic attack, myocardial infarction, and mortality were similar between the groups.

Conclusion

According to the literature, this is the first study evaluates the role of Pre-D in very severe (&gt;90%) carotid artery stenosis. The current study demonstrated that Pre-D might have a detrimental effect on in-hospital outcomes.

SURVIVIN POSITIVITY AND PROGNOSTIC FACTORS IN PAPILLARY THYROID CARCINOMAS

CONTEXT

Papillary thyroid carcinoma(PTC)s are the indolent progressive tumours. Survivin is a unique bifunctional protein with cell cycle regulation and apoptosis inhibition. The expression of this protein has been shown to be increased in thyroid tumours correlated with aggressive behavior from well differentiated to anaplastic.

OBJECTIVE

In this study, we aimed to investigate the relationship between immunohistochemically survivin expression and tumour-associated prognostic factors in papillary thyroid carcinomas.

DESIGN

In patients with thyroidectomy, we compared the clinicopathological findings and immunohistochemical positivity for survivin.

SUBJECTS AND METHODS

In 109 patients, sex, age, tumour size, histological tumour variant, tumour focality, tumour border pattern, tumour peripheral/intratumoural lymphocytic and stromal response, intraglandular spread, extrathyroideal spread, lymph node metastases, lymphocytic tiroiditis and relationships of these findings with survivin positivity were investigated.

RESULTS

When we indicated the tumour size and compared it with survivin expression, tumour size correlates with, survivin expression (p = 0.016). Survivin expression was correlated statistically significant with lymphovascular invasion, without stromal response and with intraglandular extension respectively (p<0.001, p = 0.043, p<0.001). No significant correlation was found between other clinicopathological parameters and survival.

CONCLUSION

Few studies have investigated the relationship of survivin expression with prognosis in thyroid papillary carcinomas and showed that survivin was a poor prognostic marker. If its expression is detected in preoperative cytology smears, it may affects the surgical treatment strategy. When it is detected in the tissue, postoperative radioactive iodine treatment plan may be modified and the need for more aggressive follow-up may be considered.

Effects of umbelliferone isolated from the Ferulago pauciradiata Boiss. & Heldr. Plant on cecal ligation and puncture-induced sepsis model in rats

Sepsis is a pathophysiological event involving systemic inflammatory response syndrome, multiple organ failure syndromes, and tissue damage. Overproduction of free radicals as a result of tissue damage during sepsis contributes to cellular toxicity, organ failure, and even mortality. Antioxidants, which scavenge free radicals, play a protective role against various diseases. Previous studies have shown that umbelliferone (UF) has antioxidant and anti-inflammatory effects. Since oxidative stress is naturally associated with sepsis-induced organ dysfunction, the application of antioxidant compounds could potentially illuminate the pathophysiology of sepsis, which does not yet have an effective treatment. The sepsis model induced by cecal ligation and puncture (CLP) was applied to rats. Different doses of UF (10░mg/kg, 20░mg/kg, and 40░mg/kg) on oxidant-antioxidant in septic rats, mRNA of inflammatory mediators such as tumor necrosis factor- α (TNF-α) and interleukin (IL)-1 its effects on expression levels were evaluated in lung, kidney, and liver tissues. When the lung, kidney, and liver tissues of septic rats were compared with those of the control group, it was found that UF administration increased dose-dependent superoxide dismutase activity and glutathione levels and significantly decreased malondialdehyde levels. The effects of UF administration on oxidative parameters were dose-dependent. The 40░mg/kg UF dose showed greater anti-oxidative properties than the 20░mg/kg and 10░mg/kg doses for all the evaluated parameters. Further, the TNF- α mRNA expression of the CLP +40░mg/kg group was reduced to a level comparable to that of the control group. UF has been found to be an effective molecule in reducing oxidative stress by supporting endogenous antioxidants and enhancing the scavenging effects of free radicals. The potent antioxidant property of UF may also be related to the suppression of the cytokine cascade during sepsis. The results suggest that UF administration may represent a new treatment for the prevention of lung, kidney and liver damage caused by septic conditions.

Decreases in ganglion cell layer and inner plexiform layer volumes correlate better with disease severity in schizophrenia patients than retinal nerve fiber layer thickness: Findings from spectral optic coherence tomography

Background

Optic coherence tomography (OCT) is a new, contactless and fast neuroimaging method. Previous studies have observed thinning of the retinal nerve fibre layer (RNFL) in many neurodegenerative diseases, and researchers have suggested that correlations exist between the thinning of the RNFL and the neurodegeneration detected with other imaging methods or the severity of illness. More recently, OCT has been used in patients with schizophrenia. RNFL thinning has also been detected in these patients. With more sophisticated devices, segmentation of the retina and measurements of the ganglion cell layer (GCL) and internal plexiform layer (IPL) can be performed.

Methods

We measured the RNFL thickness and the GCL and IPL volumes in 40 treatment refractory patients with schizophrenia, 41 treatment responsive refractory patients and 41 controls using spectral-OCT, and we evaluated the correlations between the disease severity and OCT measurements.

Results

The global RNFL thickness and GCL and IPL volumes were decreased in the patients with schizophrenia compared with the controls. In addition, the GCL and IPL volumes were lower in the treatment refractory patients with schizophrenia compared to the treatment responsive patients. Using parameters such as the Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression (CGI) scores, the disease duration and number of hospitalizations, correlations between the GCL and IPL volumes and disease severity were stronger than the correlations between the RNFL and the disease parameters.

Conclusion

Our findings suggest that OCT can be used to detect neurodegeneration in schizophrenia and that the GCL and IPL volumes can also be used to monitor the progression of neurodegeneration.

EFFICACY OF INSULIN, HEPARIN AND FENOFIBRATE COMBINATION TREATMENT IN SEVERE HYPERTRIGLYCERIDEMIA: DOUBLE CENTER EXPERIENCE

Context

Severe hypertriglyceridemia (SH), which calls for a triglyceride (TG) level above 1000 mg/dL, remains an important health issue. While some data exist to offer combination of heparin, insulin and fenofibrate as a reasonable treatment option, safety and benefits of this therapy have not been accurately weighted, largely due to the limited sample size of the relevant studies.

Aim

Assess the efficacy and safety of the heparin, insulin and fenofibrate combination in the treatment of patients with SH.

Patients - Methods

Patients aged ≥18 years with TG level above 1000 mg/dL and adequate organ function were included. Triglyceride levels were measured immediately before the treatment and on the 3^rd and 6^th days of the treatment. Treatment dosage, duration, response and side effects were assessed. Patients with hypertriglyceridemia presenting with acute pancreatitis were treated additionally with lipid apheresis.

Results

A total of 42 patients were included. Of these, 85.8% came to medical attention with some kind of secondary hypertriglyceridemia causes. The baseline median TG value of the cases was 2141.0 mg/ dL (1026-12250). There were 6 patients (14.3%) with acute pancreatitis at presentation. In patients without pancreatitis, with administration of insulin infusion, unfractionated heparin infusion and fenofibrate capsule, median TG values decreased to 921 mg/ dL (190-6400) on the 3^rd day and to 437 mg/ dL (112-1950) on the 6^th day of the treatment (p<0.0001, Friedman test). Potential toxicities related to insulin, heparin and fenofibrate combination treatment including hypoglycemia, hemorrhage, rise in creatine kinase levels, hepato - and nephrotoxicity were not observed.

Conclusion

In this trial involving patients with SH, our data suggest that insulin, heparin and fenofibrate combination therapy was safe and effective.

The efficiency of Levofloxacin Containing Sequential Therapy with or without Bismuth, in Helicobacter Pylori Eradication, in Non-ulcer Dyspepsia

INTRODUCTION

The aim of this study is to determine the efficiency of levofloxacin containing sequential therapy with or without bismuth in Helicobacter pylori (Hp) eradication in nonulcer dyspepsia.

MATERIALS AND METHODS

One hundred and ninety Hp-positive patients with the pre-diagnosis of nonulcer dyspepsia were included in this study. Patients were randomized into 2 groups and 95 individuals were included in each group. The first group was administered levofloxacin containing sequential therapy with bismuth, whereas the second group was administered only levofloxacin containing sequential therapy. Rates of therapy discontinuation and eradication success were compared between the 2 groups. Furthermore, symptomatic healing rates were com-pared between patients in whom Hp eradication was achieved and in whom it was not achieved.

RESULTS

Ninety-one patients from each group applied for follow-up after treatment. It was found that 7/91(7.6%) patients from the first group and 5/91(5.4%) patients from the second group did not complete the therapy (p >0.05). In patients who completed therapy, Hp eradication was achieved in 72 out of the 84 patients (85.2%) from the first group and 71 out of 86 patients (82.6%) from the second group (p > 0.05). In addition, symptomatic healing occurred in 125 out of 143 patients (87.4%) in whom Hp was eradicated and 12 out of 27 (44.4%) patients in whom Hp was not eradicated (p < 0.001).

CONCLUSION

Levofloxacin containing sequential therapy for 14 days is quite effective and well-tolerated choice for Hp eradication. However, adding bismuth to sequential therapy does not significantly improve Hp eradication success rates. Therefore, Hp eradication is beneficial and necessary in patients with nonulcer dyspepsia.

Diagnosis of fasciola hepatica cases in an operating room

Fascioliasis is a zoonotic disease that is acquired by ingestion of the metacercaria form on uncooked aquatic plants, and humans act as an accidental host. Diagnosis is confirmed by the demonstration of the parasites or evidence of them in faeces and serology. In the absence of these data, delays or misdiagnosis may occur since it may mimic many diseases. In this study, we present three cases, among them two were similar to the above-mentioned statement. The first case, to the best of our knowledge, is the first case with adult-type living fluke in the gall bladder, diagnosed by laparoscopic cholecystectomy.

A RARE CLINICAL PRESENTATION: A PATIENT WITH CHRONIC RENAL FAILURE, SECONDARY HYPERPARATHYROIDISM AND CALCIPHYLAXIS

Calciphylaxis, also known as calcific uremic arteriolopathy (CUA), is usually observed in women and it is a serious complication of hyperparathyroidism secondary to chronic renal failure. CUA is characterized by ischemic tissue loss secondary to progressive vascular degeneration. Although it is rare, it may end up with sepsis and organ failure and can be fatal. Its pathogenesis is not fully understood, but it is thought that it occurs secondary to increased calcification activators such as oxidized LDL, TNF- α, calcitriol, fibronectin, collagen-I, and TGF-1α. The most effective treatment is managing underlying pathology and decreasing serum calcium and phosphorus levels. In this report, we aimed to present an end stage renal failure case with coexisting hyperparathyroidism, hyperthyroidism and calciphylaxis in whom cutaneous manifestations were healed 6 months after parathyroidectomy.

CONCLUSION

Our findings suggest that OCT can be used to detect neurodegeneration in schizophrenia and that the GCL and IPL volumes can also be used to monitor the progression of neurodegeneration.

CLINICALLY UNDETECTABLE OCCULT THYROID PAPILLARY CARCINOMA PRESENTING WITH CERVICAL LYMPH NODE METASTASIS

Background

Occult papillary thyroid carcinoma presented as isolated cervical lymphadenopathy without clinical and radiologic findings has been rarely reported.

Case report

A 47 years old female patient admitted to otorhinolaryngology clinic with 4X3 cm sized cervical mass. Physical examination of the patient was noted as a nontender, firm, mobile lymph node at right lateral cervical region. There was no inflammatory or infection disease in the history of patients anamnesis and no abnormal value on laboratory tests. Ultrasound screening of the neck detected a lymph node with suspicious features for malignancy. Head and neck examination was normal and there is no evidence of a tumoral mass or nodule in the thyroid gland. Whole body scan of MRI showed no pathologic sign both in the neck and body. Excisional biopsy was performed and revealed a carcinoma with papillary morphology. Immunohistochemical staining features of the tumor confirmed a papillary carcinoma derived from the thyroid gland. Second look USG of the neck and thyroid was performed but it revealed no tumoral mass. The patient underwent total thyroidectomy with right functional and central lymph node dissection. Histological examination of the thyroid gland showed multicentric 2 mm sized, three foci of papillary carcinoma located in bilateral thyroid lobes and metastatic lymph nodes in the right side of the neck.

Conclusion

A metastatic cervical lymph node can be evidence of a clinically undetected occult papillary thyroid carcinoma. Specific immunohistochemistry staining of specimen may lead to appropriate surgery and progression of carcinoma may be hindered by application of additional RAI therapy.

Clinical utility of hepatic-perfusion computerized tomography in living-donor liver transplantation: a preliminary study

BACKGROUND

Vascular complications are a primary diagnostic consideration in liver transplant recipients, with an overall incidence of 9%. Cross-sectional imaging techniques provide information regarding vascular structure and luminal patency but can not quantitatively assess hepatocyte damage in the liver graft parenchyma. Perfusion computerized tomography (CT) is a recently developed method that allows for quantitative evaluation of hemodynamic changes in tissue. Our objective was to evaluate the clinical utility of perfusion CT in assessing vascular complications during living-donor liver transplantation (LDLT).

METHODS

The 33 recipients were divided into 3 groups according to Doppler ultrasonographic findings: hepatic arterial complication group, portal venous complication group, and hepatic venous complication group. Blood volume (BV), blood flow (BF), arterial liver perfusion (ALP), portal venous perfusion (PVP), and hepatic perfusion index (HPI) were calculated for the affected vascular territory regions.

RESULTS

Compared with normal liver parenchyma, BV, BF, ALP, and HPI were significantly lower in the hepatic arterial complication group. Although PVP and BV were significantly lower, ALP, HPI, and BF were higher in the affected vascular territory region than in normal liver parenchyma for the portal venous complication group. In the hepatic venous complication group, PVP was significantly higher and BF, ALP, and HPI significantly lower in the affected vascular territory regions than in normal liver parenchyma.

CONCLUSIONS

Perfusion CT imaging is a noninvasive technique that enables the quantitative evaluation of vascular complications in the graft parenchyma after LDLT and permits a quantitative evaluation of the treatment response.

Anesthetic Management in Children with Congenital Lobar Emphysema

BACKGROUND

The cause of congenital lobar emphysema (CLE) is unknown and characterized by hyperinflation of one or more lobes of the lung. The purpose of this retrospective study was to present the anesthetic management of children with congenital lobar emphysema (CLE) receiving treatment in our center.

METHODS

Ten children underwent CLE-related surgical treatment in our center between March 1995 and August 2014. All cases were diagnosed on the basis of postero-anterior chest radiography and computerized tomography. Age, sex, preoperative clinical findings, location of lesions, surgical and anesthetic procedures, results of anesthesia and duration of hospitalization were evaluated.

RESULTS

Six patients were male (60%) and four female (40%). Their ages ranged from 40 days to 6 years. Dyspnea was present in all cases and severe in four of them. Four patients had emphysema in the left upper lobe, three in the right middle lobe, one in the right upper lobe and one in the left lower lobe. All patients were extubated in the operating room and none experienced post-operative respiratory distress. Post-operative analgesia was provided via the previously placed intrapleural catheter. All the patients were extubated in the operation room. There was no post-operative mortality or morbidity.

CONCLUSIONS

Anesthetic management of patients with CLE is challenging. In these patients the surgical team and -anesthetists should collaborate closely and the time between anesthesia induction and thoracotomy should be as short as possible.

Local sympathetic stimulation not only have local effects in patients with Raynaud's phenomenon

OBJECTIVE

Many other organs and system can be affected in the course of Primary Raynaud's Phenomenon (RP). Simultaneously increased vasospasm in the pulmonary vascular bed may likely affect the pulmonary function. Therefore, we investigated the effect of Raynaud's phenomenon on the respiratory functions in this study.

PATIENTS AND METHODS

Between March 2014 and December 2014, 30 patients with the diagnosis of PRP more than two years and 32 age-sex matched healthy controls were enrolled into this study. Cold stimulation test (CST) was performed. Pulmonary function test were performed following 30 minutes after CST and spirometric measurements were calculated.

RESULTS

There were no statistically significant differences between two groups regarding their demographic and clinical data. Mean duration of symptoms from onset to present was 3.01 ± 1.05 years. Patients with Primary RP had significantly lower FVC and higher FEV1/FVC values compared to the control groups (p = 0.015 and p=0.045, respectively).

CONCLUSIONS

We found that statistically significant decrease of FVC values in patients with Primary RP compared to the healthy controls could be a impaired innervation of pulmonary system and a predictor of pulmonary vasospasm and/or pulmonary Raynaud's phenomenon, which may develop in future periods.

Increased sympathetic activation in patients with vasovagal syncope is associated with higher mean platelet volume levels

OBJECTIVES

Vasovagal syncope (VVS) is supposed to be modulated by increased sympathetic tone following an orthostatic maneuver. Increased sympathetic activity may have an important role in mean platelet volume (MPV), either by peripheral activation or by effects on thrombocytopoiesis. We aimed to show the effects of increased sympathetic activity on platelet size in patients with VVS in the present study.

PATIENTS AND METHODS

Thirty-seven patients with VVS were compared with age- and sex-matched 33 patients without VVS. All patients have undergone 24 hour holter monitoring for heart rate variability (HRV) and time-domain HRV analysis. Blood samples for MPV measurements were taken before 24 hour holter monitoring.

RESULTS

Group 1 was consisted of 37 patients with VVS and group 2 was consisted of 33 patients without VVS. We observed that SDNN, SDNN index, SDSD, RMSDD, PNN50 count were significantly lower and MPV was found significantly higher in patients with VVS (p < 0.05 for all). Pearson's correlation analysis showed that MPV was moderately negatively correlated with SDNN (r = -0.421), SDSD (r = -0.396), NN50 count (r = -0.395) and RMSDD (r = -0.393). Multivariate regression analysis showed that SDNN was the only independent variable, which had a significant effect on increased MPV level (β = -0.295 , p = 0.016).

CONCLUSIONS

We found that MPV was closely associated with increased sympathetic activity in patients with VVS. Our analysis supports the hypothesis that alterations in autonomic status might play a role in the development of platelet size.

Higher red cell distribution width values are associated with impaired exercise capacity during exercise treadmill testing in patients without obstructive coronary disease: a preliminary study

BACKGROUND

Red cell distribution width (RDW) is associated with poor cardiovascular outcomes. We aimed to find out if this association could be explained by impaired exercise capacity in patients without obstructive coronary artery disease (CAD).

PATIENTS AND METHODS

The patients who underwent exercise treadmill test (ETT) who have non-obstructive CAD and were free of heart failure symptoms were evaluated. Total of 132 patients were enrolled, and patients were divided into three groups according to their Metabolic Equivalent Task (MET) level measured by exercise treadmill test (ETT): Less than 7 METs (group 1), 7-10 METs (group 2) and greater than 10 METs (group 3).

RESULTS

The patients in Group 1 had significantly higher RDW levels (16.46 ± 2.79) compared to Group 2 (15.05 ± 2.03) and Group 3 (14.52 ± 1.37), independent of hemoglobin and hematocrit values. Significant differences for age, gender, duration of ETT and Duke Treadmill Score were also found in proportion to the reduced exercise capacity. In multivariate analysis, only duration of ETT (β = 1.017, p = < 0.001) and RDW (β = 0.040, p = 0.026) were found as independent variables, which had statistically significant effects on METs.

CONCLUSIONS

We found an independent association between RDW and exercise capacity in patients free of obstructive coronary disease suggesting that patients with elevated RDW values are expected to have impaired exercise capacity.

Patients with psoriasis have an increased amount of epicardial fat tissue

BACKGROUND

Psoriasis is associated with coronary artery disease, and ischemic heart disease is associated with increased amounts of epicardial fat tissue (EFT). There has as yet been no study published on the accumulation of EFT in patients with psoriasis.

AIM

To compare epicardial fat accumulation and coronary artery calcium score (CACS) in patients with psoriasis and controls.

METHODS

We enrolled 38 patients with psoriasis and 38 controls matched for age and gender. Epicardial fat area (EFA) and CACS were evaluated by multidetector computed tomography.

RESULTS

Mean EFA in patients with psoriasis was significantly higher than in controls (13.8 ± 8.4 vs. 9.7 ± 6.4 cm(2) , respectively, P = 0.02), but mean CACS did not differ significantly between the two groups (55.2 ± 65.4 vs. 27.8 ± 29.3; P > 0.05). Multiple linear regression analyses indicated that EFA was significantly associated with waist circumference and presence of coronary artery calcification in both patients and controls, whereas EFA was significantly associated waist circumference and age in patients only (P < 0.05).

CONCLUSIONS

Patients with psoriasis had a higher level of EFA compared with controls, and EFA was independently associated with the presence of CAC in all study subjects.

Determination and clinical correlation of markers of inflammation in unvaccinated patients with varicella-zoster infection

BACKGROUND

Chicken pox is commonly known as a benign exenthamatous disease of childhood, occasionally neurologic or hemorrhagic complications, or even death may ensue. Early predictors of severity of disease have yet to be identified. TNF-alpha and IL-6 stimulate virus-specific immunoglobulin production and it has been postulated that determination of levels of these cytokines may be useful as a prognostic factor.

PATIENTS AND METHODS

Patients who were diagnosed with a varicella-zoster virus (VZV) infection in the Outpatient Clinic of the Department of Pediatric Infectious Diseases were evaluated for eligibility. Laboratory assays included an evaluation of complete blood counts, erythrocyte-sedimentation rate (ESR), c reactive protein (CRP), and the number of tumor necrosis factor-alpha/interleukin-6-(TNF-alpha/IL-6-) producing mononuclear cells as determined by flow cytometry.

RESULTS

A total of 339 patients (320 with chickenpox and 19 with shingles) were enrolled. Blood samples could only be obtained from 81 of the 320 patients with chickenpox. Patients were also divided into three groups depending on the number of skin (vesicular) lesions. (group 1, ≤ 50 lesions; group 2, 51-100 lesions; group 3, >100 lesions). Correlation analyses did not reveal the presence of a statistically significant correlation between number of skin lesions with either of white blood cells (WBC) count (p = 0.231), ESR (p = 0.879) or CRP (p = 0.373). The mean percentage of TNF-alpha-producing mononuclear cells was significantly higher in group 2 compared to group 3 (p = 0.003). A similar difference was observed with regard to IL-6-producing mononuclear cells, albeit bordering on statistical significance (p = 0.058).

CONCLUSIONS

Decreased expression of the cytokines TNF-alpha and IL-6 may be responsible for the development of a more severe clinical picture in patients with VZV infection, and determination of intracellular levels of these cytokines may be of benefit for early identification of patients who may have a more severe clinical course.
