Sphingomonas paucimobilis bacteraemia and shock in a patient with rheumatic carditis.

Acute rheumatic fever (ARF) carditis is treated with steroids, which can cause changes in the cellular immune response, especially decreased CD3 (+) T cells. Nosocomial infections due to steroid use for treatment of ARF carditis or secondary to the changes in the cellular immune response have not been reported in the literature. Sphingomonas paucimobilis is a Gram-negative bacillus causing community- and hospital-acquired infections.

Mid-term assessment of cardiac autonomic functions in children with transposition of the great arteries after arterial switch operation.

Point mutation frequency in the FMR1 gene as revealed by fragile X syndrome screening.

Fragile X syndrome (FXS) is a common cause of intellectual disability, developmental delay and autism spectrum disorders. This syndrome is due to a functional loss of the FMR1 gene product FMRP, and, in most cases, it is caused by CGG repeat expansion in the FMR1 promoter. Yet, also other FMR1 mutations may cause a FXS-like phenotype.

Carotid artery intima-media thickness (cIMT), flow-mediated dilation (FMD) and carotid stiffness index were measured by using a carotid Doppler and real-time ultrasound.

Increased P-wave and QT dispersions necessitate long-term follow-up evaluation of Down syndrome patients with congenitally normal hearts.

Reports state that Down syndrome (DS) patients with congenitally normal hearts might experience the development of cardiac abnormalities such as cardiac autonomic dysfunction, valvular lesions, bradycardia, and atrioventricular block. However, the presence of any difference in terms of P-wave dispersion (PWd) and QT dispersion (QTd) was not evaluated previously. This study prospectively investigated 100 DS patients with structurally normal hearts and 100 age- and sex-matched healthy control subjects.

Seroprevalence of serum HBsAg positivity and hepatitis delta virus infection among blood donors in Southeastern Turkey.

Objective : To evaluate the value of neurologic and cardiologic assessment and also the frequency of iron deficiency anemia in children with Breath Holding Spells (BHS). Methods : The hospital charts of patients diagnosed with BHS between 2011 and 2013 were reviewed retrospectively. Results : A total of 165 children (90 boys, 75 girls) with BHS comprised the study group.

P-wave dispersion: an indicator of cardiac autonomic dysfunction in children with neurocardiogenic syncope.

Neurocardiogenic syncope is the most frequent cause of fainting in childhood and adolescence. Although head-up tilt table testing (HUTT) was previously considered as the reference standard in the diagnosis of syncope, in children with a typical history of reflex syncope, normal physical examination, and electrocardiogram (ECG) are sufficient to cease investigation; however, according to recent reports, TT is indicated in patients in whom this diagnosis cannot be proven by initial evaluation. The hypothesis of this study is that P-wave dispersion (PWD) can be a useful electrocardiographic predictor of cardiac autonomic dysfunction in children with vasovagal syncope (VVS).

Evaluation of left atrial functions in children with chronic renal failure.

Objective: One-quarter of deaths in children with chronic renal failure is due to cardiovascular complications.

Importance of close follow-up in the fetus with premature atrial contractions accompanied by atrial septal aneurysm: a case report.

Rhythms that derive from parts of atria other than the sinus node are called premature atrial contractions (PACs). Vast majority of fetal PACs are idiopathic. Fetal PACs usually have a good prognosis and disappear spontaneously during pregnancy or after delivery.

Association between serum pregnancy-associated plasma protein-A and bicarbonate in hemodialysis patients.

Background: Acidosis is associated with protein-energy malnutrition, inflammation, and bone disease, and low bicarbonate levels have been implicated in higher mortality rates in chronic kidney disease. Recently, the concentration of serum pregnancy-associated plasma protein-A (PAPP-A) has become accepted as a prognostic marker in hemodialysis patients. This study determined the relationship between PAPP-A and bicarbonate levels in these patients.

Postural orthostatic tachycardia syndrome (POTS) and vitamin B12 deficiency in adolescents.

Objective: Vitamin B12 is involved in the production of adrenaline from noradrenaline. It is the cofactor involved in catecholamine degradation and plays a role in myelin synthesis. The current study aimed to investigate the association between vitamin B12 levels and postural orthostatic tachycardia syndrome (POTS) during adolescence when accelerated myelin synthesis increases the vitamin B12 need.

Chitosan-ionic liquid modified single-use sensor for electrochemical monitoring of sequence-selective DNA hybridization.

Chitosan-(CHIT) and ionic liquid- (1-butyl-3-methylimidazolium hexafluorophosphate (IL)) modified single-use graphite electrodes (PGEs) were developed for the first time in the present study for the enhanced monitoring of DNA, and also for sequence-selective DNA hybridization by measuring the guanine oxidation signal. The electrochemical behaviour of the CHIT-IL modified electrodes was first investigated (with unmodified electrodes as controls) using electrochemical impedance spectroscopy (EIS) and differential pulse voltammetry (DPV). Sequence-selective DNA hybridization related to Hepatitis B virus (HBV) was also evaluated in the case of hybridization between amino-linked HBV probe and its complementary (target), a noncomplementary (NC) sequence, single base mismatch (MM), and also in the medium of target/mismatch (MM) mixtures (1:1).
