Role of diabetes in heart rhythm disorders.

The incidence of diabetes mellitus (DM) is increasing rapidly. DM is the leading cause of cardiovascular diseases, which can lead to varied cardiovascular complications by aggravated atherosclerosis in large arteries and coronary atherosclerosis, thereby grows the risk for macro and microangiopathy such as myocardial infarction, stroke, limb loss and retinopathy. Moreover diabetes is one of the strongest and independent risk factor for cardiovascular morbidity and mortality, which is associated frequently with rhythm disorders such as atrial fibrillation (AF) and ventricular arrhythmias (VA).

Trade-off between angular and spatial resolutions in in vivo fiber tractography.

Tractography is becoming an increasingly popular method to reconstruct white matter connections in vivo. The diffusion MRI data that tractography is based on requires a high angular resolution to resolve crossing fibers whereas high spatial resolution is required to distinguish kissing from crossing fibers. However, scan time increases with increasing spatial and angular resolutions, which can become infeasible in clinical settings.

The effect of colloid preload versus prophylactic ephedrine administration on QTc intervals during cesarean delivery: A randomized controlled study.

Aim: We aimed to investigate the effect of colloid infusion immediately before the spinal anesthesia, and the prophylactic intravenous (IV) infusion of ephedrine after injection of intrathecal bupivacaine on hemodynamic parameters, QT, The QT interval corrected for heart rate (QTc), and dispersion of QTc (QTcDisp) intervals in women undergoing the elective cesarean section.

Materials And Methods: Sixty women scheduled for elective cesarean delivery with spinal anesthesia were allocated randomly to receive either IV fluid preloading with 0.5 L of 6% w/v hydroxyethyl starch solution immediately before the spinal anesthesia (colloid group, n = 30) or prophylactic IV infusion of 15 mg ephedrine (diluted with 10 ml saline, n = 30) over 1-min period after the injection of intrathecal bupivacaine (ephedrine group).

Percutaneous approach to the treatment of a totally occluded abdominal aortic stent graft.

Aorto femoral bypass is usually the recommended therapy for diffuse disease involving the aorta and iliac arteries. In this case report, a case involving a chronic endovascular abdominal aortic stent graft occlusion in which percutaneous angioplasty was performed via a transbrachial and transfemoral approach is presented. This case emphasized that occlusion of an endovascular abdominal aortic stent graft can also be treated, primarily, with an endovascular technique.

HELLP syndrome is still a serious, life-threatening complication of pregnancy: admission of 34 women to an eastern Turkish intensive care unit.

Objective: The transfer of the obstetric patient to the intensive care unit is considered as an indicator of maternal morbidity. The most important two indications for admittance of the obstetric patient to the intensive care unit are postpartum hemorrhage and hypertensive disorders. The purpose of this study was to determine maternal morbidity and mortality rates in patients diagnosed with hemolysis, elevated liver enzyme levels, and low platelet count (HELLP) syndrome who required intensive care.

[Anesthetic management of a pediatric patient with hypohidrotic ectodermal dysplasia undergoing emergency surgery].

Ectodermal dysplasias are rare conditions with a triad of hypotrichosis, anodontia and anhidrosis. In literature review there have been only a few reports of anesthetic management of patients with ectodermal dysplasias. Hyperthermia is a very serious risk which may occur due to the defect of sweat glands.

Jugular Venous Catheterization: A Case of Knotting.

A 79-year-old woman, diagnosed for cancer of the ovary, had a central catheter that was placed with difficulty through the right internal jugular vein intraoperatively. After oophorectomy, it was realized that the catheter was knotted. Thus, the central venous catheter was removed successfully using a traction technique in the operating room.

Critical role of Chlamydomonas reinhardtii ferredoxin-5 in maintaining membrane structure and dark metabolism.

Photosynthetic microorganisms typically have multiple isoforms of the electron transfer protein ferredoxin, although we know little about their exact functions. Surprisingly, a Chlamydomonas reinhardtii mutant null for the ferredoxin-5 gene (FDX5) completely ceased growth in the dark, with both photosynthetic and respiratory functions severely compromised; growth in the light was unaffected. Thylakoid membranes in dark-maintained fdx5 mutant cells became severely disorganized concomitant with a marked decrease in the ratio of monogalactosyldiacylglycerol to digalactosyldiacylglycerol, major lipids in photosynthetic membranes, and the accumulation of triacylglycerol.

The purpose of this study was to evaluate the effects of pre-emptive single-dose pregabalin on postoperative acute pain and 24-hour opioid consumption in patients who underwent double-jaw surgery.

Patients And Methods: Forty patients (18 to 45 yr old; American Society of Anesthesiologists status I to II) for whom elective double-jaw surgery was planned under general anesthesia were included in this study, which had been planned as a prospective, randomized, and double-blinded study.

Analysis of the cause, classification, treatment, outcome and associated injuries of pediatric pelvic ring fractures.

Background: Although pediatric pelvis fractures are relatively uncommon, long-term consequences and associated life-treating injuries often have a substantial impact for the rest of a child's life. The prognosis of pediatric pelvic fractures is better than that of the adults because of their greater elasticity, healing capacity and re-modelling. Fractures through the physis may lead to growth disturbance and/or acetabular dysplasia.

Spinal anaesthesia at low and moderately high altitudes: a comparison of anaesthetic parameters and hemodynamic changes.

Background: Hypoxemia caused high altitude leads to an increase and variability in CSF volume. The purpose of this prospective study was to detect the differences, if any, between moderately highlanders and lowlanders in terms of anaesthetic parameters under neuroaxial anaesthesia.

Methods: Consecutive patients living at moderately high altitude (Erzurum, 1890 m above the sea level) and sea level (Sakarya, 31 m above the sea level) scheduled for elective lower extremity surgery with spinal anaesthesia were enrolled in this study (n = 70, for each group).
