Article Synopsis
  • * Most patients (76 boys and 14 girls) had right or left pneumothorax, and initial treatment included tube thoracostomy, with some undergoing video-assisted thoracoscopic surgery (VATS) for recurring cases.
  • * The results indicate a success rate of over 90% for VATS treatments, which are deemed more effective and safer than traditional chest tube insertion due to lower recurrence rates.

Cases of embedded unexploded ordnance are extremely rare and pose a risk to bystanders and health providers. A patient arrived at the Role 2 medical facility in the Turkish army, whose left arm was amputated due to a terrorist attack and major hemorrhages had been halted by clamping of the left subclavian artery and vein. A piece of metal wire running from the lateral chest wall was detected as an unexploded ordnance piece and it was removed surgically.

Recent developments in telecommunication world have allowed customers to share the storage and processing capabilities of their devices by providing services through fast and reliable connections. This evolution, however, requires building an incentive system to encourage information exchange in future telecommunication networks. In this study, we propose a mechanism to share bandwidth and processing resources among subscribers using smart contracts and a blockchain-based incentive mechanism, which is used to encourage subscribers to share their resources.

Background: Conventional fluoroscopy guided catheter ablation (CA) is an established treatment option for ventricular arrhythmias (VAs). However, with the complex nature of most procedures, patients and staff bare an increased radiation exposure. Near-zero or zero-fluoroscopy CA is an alternative method which could substantially reduce or even eliminate the radiation dose.

Catheter radio-frequency ablation (RFA) and cryo-ablation (CRA) procedures are an effective and safe treatment options for adult and pediatric patients with accessory pathway (AP) mediated tachycardias. Non-fluoroscopic techniques during catheter ablation (CA) procedures reduce potentially harmful effects of radiation. Our aim was to investigate the efficacy and safety of completely fluoroless RFA and CRA procedures in pediatric and adult patients with APs.

Background: Radiofrequency ablation (RFA) and cryo-ablation (CRA) have been traditionally performed with fluoroscopy which exposes patients and medical staff to the potential harmful effects of the X-ray. Therefore, we aimed to assess the feasibility, safety, and effectiveness of RFA and CRA of atrioventricular nodal reentry tachycardia (AVNRT) guided by the three-dimensional (3D) electro-anatomical mapping (EAM) system without the use of fluoroscopy.

Methods: We analyzed 168 consecutive patients with AVNRT, 62 of whom were under 19 years of age (128 in RFA (age 34.

Background: The relationship between serum uric acid and arterial stiffness or blood pressure is not clear. The serum uric acid level and its association with cardiovascular risk is not well known in patients with reduced renal mass. We aimed to investigate the relation between serum uric acid levels and arterial stiffness and also blood pressure in patients with congenital renal agenesis and/or hypoplasia.

Background: The aim of our study was to evaluate in stable outpatients with systolic heart failure (HF) the 3 months effect of ivabradine on LV synchronization and Tei index in stable outpatients with systolic HF.

Methods: We evaluated prospectively 40 (30 males, 10 females) patients with HF. All patients were evaluated before and after treatment by transthoracic M mode, two dimensional (2D), pulsed-wave (PW), continuous wave (CW), color flow and tissue Doppler imaging (TDI) and tissue synchronization imaging (TSI).

Background: We sought to validate total atrial conduction time (TACT) measurement via tissue Doppler imaging (TDI) by comparing the electrophysiological study (EPS) measurements of healthy subjects, according to age and sex.

Methods: Eighty patients with normal EPS results were included. TACT was measured by EPS and TDI.

Objective: This study aims to evaluate the effect of bladder diverticula (BD) on bladder function using a rabbit model, based on urodynamic findings.

Methods: A total of 32 New Zealand white rabbits were randomly assigned to four groups: (1) sham surgery; (2) a single, 1-cm-diameter BD; (3) a single, large, 3-cm-diameter BD; and (4) four (multi) 1-cm-diameter BD. Urodynamic evaluations were performed preoperatively, and 1week and 1month postoperatively, to measure the postmicturition residual (PMR), maximum bladder capacity (MBC), filling and voiding detrusor pressure (Pdet), compliance, and unstable detrusor contractions.

Aim: Heart rate (HR) reduction with ivabradine improves left ventricle filling by the prolongation of the diastolic time and increases stroke volume. But, it remains unclear what ivabradine's effect is on atrial conduction time and atrial mechanical functions. The aim of our study was to evaluate in stable outpatients with systolic heart failure (HF) the 3 months effect of ivabradine on atrial conduction time and mechanical functions.

Objective: The purpose of the present study was to investigate autonomic tone during the follicular and luteal phases of the menstrual cycle using heart rate variability (HRV) and heart rate recovery (HRR) in healthy women.

Subjects And Methods: Thirty women aged 22-37 years with regular menstrual cycles were included in the study. The HRV and HRR were measured at the follicular and luteal phases.

Aim: To investigate whether there is a relation between neutrophillymphocyte (N/L) and platelet- lymphocyte (P/L) ratios and epicardial adipose tissue (EAT) thickness in patients with ankylosing spondylitis (AS).

Methods: Thirty patients diagnosed with ankylosing spondylitis and 25 healthy people (controls) were included in the study. Age, gender, body mass index (BMI), height, hemogram, sedimentation, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, CRP, hepatic and renal function tests, lipid profile of the all patients were recorded.

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.

Aim: The aim of this study was to evaluate functional and prognostic benefits of Doppler ultrasonography (DU), diuretic renal scintigraphy (DRS), and magnetic resonance urography (MRU) during diagnosis and follow-up of ureteropelvic junction obstruction (UPJO) and to examine apoptosis rates caused by UPJO in an experimental rabbit model.

Method: Twenty-four rabbits were divided randomly into two groups. The left kidneys of 15 rabbits from the first group underwent Ulm-Miller surgery to create UPJO, whereas the left kidneys of nine rabbits from the second group underwent sham surgery.

Background: The diagnosis of palpitation can be difficult in the emergency department (ED) and the waiting time for a first appointment with an arrhythmia clinic can be very long. The inflammation is sufficient to facilitate the initiation of supraventricular tachyarrhythmia (SVT). The increased mean platelet volume (MPV) is closely correlated with inflammation and to reflect inflammatory burden in different condition.

Background/aims: Abnormalities in atrial electromechanical delay (EMD) times and mechanical functions are considered as independent predictors of atrial fibrillation. However, to date, effects of a single hemodialysis (HD) session and acute volume-preload changes on atrial-EMD functions have not been investigated by Tissue Doppler Echocardiography (TDE). The aim of the present study was to evaluate atrial-EMD times and mechanical functions in HD patients.
