Acute alcohol consumption is associated with increased interatrial electromechanical delay in healthy men

Background: Acute alcohol consumption can cause atrial fibrillation in patients with, and without, heart disease. Increased atrial electromechanical delay (EMD) has been associated with atrial fibrillation. We evaluated the atrial conduction properties by tissue Doppler imaging (TDI) echocardiography in healthy men following acute alcohol intake. Methods: Thirty healthy male volunteers were included in this study. Baseline ECG, heart rate, blood pressure, and TDI echocardiographic findings were compared to readings taken one hour after drinking six 12-oz cans of beer (76.8 g of ethanol). Results: Although the blood pressure and heart rate remained similar before and one hour after alcohol intake, Pmax and Pd values were significantly prolonged (114.2 &#177; 10.4 vs 100.8 &#177; 10.6, p = 0.002; 50.6 &#177; 9.6 vs 34.5 &#177; 8.8, p < 0.0001). Interatrial EMD was significantly increased after drinking alcohol compared to the baseline (19.8 &#177; 9.2 vs 14.0 &#177; 5.5 ms, p < 0.0002). Conclusions: Acute moderate alcohol intake was associated with an increased interatrial EMD obtained by TDI echocardiography. This finding may help explain how these patients express increased susceptibility to atrial fibrillation. (Cardiol J 2011; 18, 6: 682&#8211;686

Determinants of high sensitivity troponin T concentration in chronic stable patients with heart failure: Ischemic heart failure versus non-ischemic dilated cardiomyopathy

Background: Cardiac troponin T is a marker of myocardial injury, especially when measured by means of the high-sensitivity assay (hs-cTnT). The echocardiographic and clinical predictors of hs-cTnT may be different in ischemic heart failure (IHF) and non-ischemic dilated cardiomyopathy (DCM).Methods: Sixty consecutive patients (19 female, 41 male; mean age 56.3 ± 13.9 years) with stable congestive heart failure (33 patient with IHF and 27 patients with DCM), with New York Heart Association functional class I–II symptoms, and left ventricular ejection fraction &lt; 40% were included.Results: In patients with IHF peak early mitral inflow velocity (E), E/peak early diastolic mitral annular tissue Doppler velocity (Em) lateral, peak systolic mitral annular tissue Doppler velocity (Sm) lateral and logBNP were univariate predictors of hs-cTnT above median. But only E/Em lateral was an independent predictor of hs-cTnT above median (p = 0.04, HR: 1.2,CI: 1–1.4). In patients with DCM; left atrial volume index, male sex, Sm lateral and global longitudinal strain (LV-GLS) were included in multivariate model and LV-GLS was detected to be an independent predictor for hs-cTnT above median (p &lt; 0.05, HR: 0.7, CI: 0.4–1.0).Conclusions: While LV-GLS is an independent predictor of hs-cTnT concentrations in patients with DCM, E/Em lateral predicted hs-TnT concentrations in patients with IHF

Collet-Sicard Syndrome Associated with Occipital Condyle Fracture and Epidural Hematoma

A 31-year-old male was presented with a very rare case of ipsilateral palsies of the nerves IX through XII (Collet-Sicard syndrome) after a closed head injury. An occipital condyle fracture that was associated with epidural hematoma was diagnosed by computed tomography. The patient was conservatively managed, and following the treatment, partial neurological recovery ensued. The phenomenon of occipital condyle fracture involving the last four cranial nerve palsies is relatively rare. Although 3 cases of Collet-Sicard syndrome that were caused by an occipital condyle fracture has been reported, the association between condyle fracture and epidural hematoma has never been described before

The real life data of ranibizumab use among the diabetic macular edema patients in Turkey: Documenting the improvement with clinical optimization during three consecutive years

Purpose: To report the 12 month real life outcomes of ranibizumab treated diabetic macular edema (DME) patients. Methods: Treatment naïve DME patients treated with ranibizumab were included. Patients were divided into three groups according to their hospital admittance years (2013, 2014, and 2015) and were compared in regards to the treatment outcomes. Results: The mean visual acuity change from baseline to month 12 was not statistically significant in 2013 at month 12. The mean BCVA change from baseline to month 12 was statistically better at month 12 in 2014 and 2015. There was a statistically significant difference among the three groups in regards to both mean visit and injection numbers. The mean visit number in 2013 and 2014 were both lower than 2015. The mean injection number in 2013 was lower than both 2014 and 2015. Conclusions: It is effortful to obey the strict follow-up criteria of prospective studies in DME patients on a PRN regimen. However, optimizing the clinical processes of patient management may lead to improved clinical outcomes in real life. Keywords: Diabetic macular edema, Intravitreal injection, Ranibizuma

Evaluation of posterior clinoid process pneumatization by multidetector computed tomography

WOS: 000403546200006PubMed: 27766486In the present study, we investigated the types and ratio of posterior clinoid process (PCP) pneumatization in paranasal sinus multidetector computed tomography (MDCT). Paranasal MDCT images of 541 subjects (227 males, 314 females), between 15 and 65 years old, were included into the study. Pneumatization of anterior clinoid process and pneumatization types (I, II, or III) were evaluated in the males and females. PCP pneumatization was detected in 20.7 % of the males and 11.5 % of the females. Right, left, and bilateral PCP pneumatizations were detected in 7.9, 5.7, and 7.0 % of the males and 2.9, 3.2, and 4.5 % of the females, respectively. PCP pneumatization of the males is significantly higher than the females. The most detected type of pneumatization was type I (61.2 %) for all groups. In right, left, and bilateral pneumatizations separately, type I pneumatization was the most detected pneumatization type with the ratio of the 70.4, 65.2, and 50.0 %, respectively. In males, type I (61.7 %), and similarly in females, type I (60.6 %) pneumatization were detected more. Type II and type III pneumatizations were detected in decreasing order in both groups. In younger subjects, pneumatization of posterior clinoid process was found as higher, and in older subjects, PCP pneumatization was found as lower. Sclerosis process related to the aging may be responsible for the lower pneumatization ratios in older subjects. Structure of the surrounding regions of PCP is important for surgical procedures related to cavernous sinus, basilar apex aneurysms, and mass lesions. Preoperative radiological examinations are useful for operative planning. Any anomalies to PCP can cause unnecessary injury to the neurovascular complex structure around the cavernous sinus or postclinoidectomy CSF fistulas. Posterior clinoidectomies should be avoided in patients with type III PCP pneumatization to prevent CSF fistulas

Sonoelastographic evaluation of the sciatic nerve in patients with unilateral lumbar disc herniation

celebi, umut orkun/0000-0003-2539-2525WOS: 000452667500013PubMed: 29982854ObjectiveThe aim of this study was to compare strain elastography (SE) and shear wave elastography (SWE) findings of the sciatic nerve in patients with unilateral lumbar disc herniation (LDH) and healthy control subjects.Materials and methodsThe study group included patients with complaints of unilateral sciatica for 3-12months, with foraminal stenosis due to one level of LDH (L4-L5 or L5-S1). An age- and gender-matched control group was formed of healthy subjects. Evaluations were performed on both the axial and longitudinal planes from the bilateral gluteal region using a 5-9MHz multifrequency convex probe.ResultsThere were 40 patients (20 male, 20 female) with a mean age of 43.112.7years in the study group, and 40 healthy subjects (22 male, 18 female) with a mean age of 42.9 +/- 10.7years in the control group (p>0.05). The sciatic nerve stiffness assessed on both the axial (12.3 +/- 3.7 kPA) and longitudinal (14.3 +/- 3.8 kPA) planes of the involved side was significantly higher than non-involved side (axial: 6.8 +/- 2.1 and longitudinal: 8.3 +/- 2.3 kPA) in the patient group (p<0.001).Conclusions p id=Par4 Patients with unilateral LDH have increased stiffness of the sciatic nerve compared to healthy control subjects. Although the findings in this preliminary study show that shear wave elastography can detect a change in sciatic nerve stiffness in patients with unilateral LDH, larger studies are required to determine the clinical utility of this technique
