Effects of inhaled corticosteroids on growth in asthmatic children: a comparison of fluticasone propionate with budesonide.

In asthmatic children inhaled corticosteroids are widely used. However, there are some concerns about the systemic adverse effects of these drugs, especially in the growing child. We performed this prospective study in order to compare the effects of 400 microg/day of budesonide (BUD) and 250 microg/day of fluticasone propionate (FP) on growth in prepubertal (aged 4-11.5 years), moderate persisting asthmatic children. One hundred patients (51 boys and 49 girls), who were randomized into two groups, were recruited for the study. The first group was treated with BUD, 2X 200 microg/day, and the second group was treated with FP, 2X 125 microg/day, by using a medium-size volume-spacer metered-dose inhaler. Growth in children with asthma who were treated by inhaled corticosteroids was calculated by growth velocity over a 12-month period. Comparisons between treatment groups were calculated by t-test and chi-square test. There were no significant differences between BUD and FP groups for sex, age, first height, and growth velocity. Moderate persisting, prepubertal asthmatic children treated with 250 microg/day of FP appeared to have no different linear growth than those children who received 400 microg/day of BUD.     

Cervical tuberculosis in early childhood

CASE HISTORY: We present a case of spinal tuberculosis in a 4-year-old girl that grounds severe vertebral destruction involving four cervical vertebrae and a large abscess with retropharyngeal expansion. Presenting symptoms were neck and right arm pain, torticollis and weakness of the right arm. We drained the abscess and removed the infected bone and reconstructed the cervical spine with a fibular allograft. The neurological deficits were recovered and the torticollis was straightened up. CONCLUSION: We emphasize the value of early diagnosis of spinal tuberculosis and early radical surgery with spinal reconstruction.     

Expression of NOS isoforms in internal spermatic veins of infertile men with varicocele

Although varicocele is a relatively common entity encountered in the evaluation of infertile men, the exact pathophysiology still remains unclear. Recently, as previously widely investigated in various parts of human circulatory system, nitric oxide synthase (NOS) and its product, nitric oxide (NO) have been thought to play a role in the development of varicocele and thus male infertility. In this study, we determined the concentration of NO metabolite and the expression of NOS isoforms in the internal spermatic (ISV) and superficial branch of inferior epigastric veins of infertile men with varicocele. The study included 60 infertile men with clinically unilateral or bilateral varicocele. Expression of inducible and endothelial NOS (iNOS and eNOS) isoforms were investigated in tissue arrays of internal spermatic and superficial branch of inferior epigastric veins with immunohistochemistry. NO metabolite (nitrite) levels were measured using the calorimetric method. A significantly higher expression of eNOS was observed in the varicose veins (mean score: 2.25 and 1.55, respectively; p?=?0.0001). However, statistically, there was no significant difference for expression of iNOS between varicose and control veins (p?=?0.094). The nitrite concentration and NOS expression were not found to be correlated with clinical variables (varicocele grade, maximum varicose vein diameter, and sperm concentration, motility, and morphology) (p?>?0.05). As a result, the significantly higher expression of eNOS in ISV may be responsible for the development of varicocele, although this finding is not accompanied by an increase in NO concentration. Still, the pattern of the relationship between varicocele and increased eNOS expression warrants further investigation.     

Is the Preoperative Administration of Amiodarone or Metoprolol More Effective in Reducing Atrial Fibrillation: After Coronary Bypass Surgery?

This study examined the influence of preoperative administration of amiodarone and metoprolol in preventing postoperative atrial fibrillation (AF) after coronary artery bypass grafting (CABG) surgery.The study comprised 251 patients who underwent CABG surgery at our hospital between January 2012 and May 2014. The patients were randomly divided into 2 groups: amiodarone therapy group (n = 122 patients) and metoprolol therapy group (n = 129 patients).In the amiodarone group, the patients received amiodarone tablet orally 1 week before coronary bypass surgery and during the postoperative period. In the metoprolol group, the patients received metoprolol tablet orally 1 week before surgery and during the postoperative period. The AF development rate was retrospectively evaluated between the first 3 days and 4 weeks after surgery.AF developed in 14 patients in the amiodarone group and 16 patients in the metoprolol group 4 weeks after the operation (P = 0.612).No significant difference was observed between the groups in terms of intensive care unit and hospital stay. Furthermore, hospital charges were similar in both groups (P = 0.741).The results of the logistic regression analysis showed age, left ventricular ejection fraction, left atrial diameter, and aortic cross-clamping time to be predictors for postoperative AF.This study demonstrates that amiodarone and metoprolol have similar effects in prevention of AF after cardiac surgery. However, larger-scale studies need to be conducted to substantiate these findings.     

Epicardial fat thickness in patients with rheumatoid arthritis

Background

Epidemiologic data indicates that rheumatoid arthritis is an independent risk factor for cardiovascular disease. Epicardial adipose tissue is a novel cardio-metabolic risk factor. Our aim was to evaluate epicardial fat thickness (EFT) using echocardiography in patients with rheumatoid arthritis compared to healthy control subjects. Secondly, we investigated relationship between epicardial fat thickness and clinical and echocardiographic parameters in patients with rheumatoid arthritis.

Method

The study population included 76 consecutive patients with rheumatoid arthritis (64 female; mean age, 53 ±11 years, median disease duration, 7.8 years) and 50 healthy subjects as controls (39 female; mean age, 52 ± 6 years). All patients underwent echocardiography to assess left ventricular diastolic dysfunction, left ventricular hypertrophy and EFT. All values were compared between groups.

Results

EFT was higher in rheumatoid arthritis patients than in healthy controls (0.66±0.20 vs. 0.54±0.18; p= 0.003). Thickness of Intra Ventricular Septum (IVS) (1.1±0.06 and 9.8±0.08; p=0.001) and posterior wall (PW) (0.98±0.05 and 0.93±0.08; p=0.015) was higher in patients with rheumatoid arthritis compared to healthy controls. Early diastolic myocardiac peak velocity or late diastolic mitral peak velocity (E/A) ratio was lower in rheumatoid arthritis patients compared to healthy patients (1.1 ±0.8 and 1.24±0.1 p=0.001) as well as, E/e'' was higher in Rheumatoid arthritis (RA) patients than healthy patients. (E/e'':8.7±1.6 and 8.0±1.4 p=0.020). In patients with rheumatoid arthritis, EFT was positively correlated with hypertension and duration of disease and E/e'' (r: 0.10, p: 0.010, r: 0.306, p: 0.004 and r: 0.465 p: 0.007 respectively) and EFT was negatively correlated with E/A (r: −.262 p:0.022)

Conclusion

To our knowledge, this is the first report about epicardial adipose tissue in rheumatoid arthritis patients. Epicardial fat thickness as an indicator of cardiovascular involvement was higher in rheumatoid arthritis patients.
