In previous studies mechanical dispersion (MD) predicted ventricular arrhythmias independently of left ventricular ejection fraction (LVEF). Moreover the combination of MD and global longitudinal strain (GLS) increased the prediction of arrhythmic events. We investigated the prognostic value of a new 2D-strain index, GLS/MD, in patients with heart failure (HF). We analysed 340 consecutive HF outpatients in sinus rhythm. Echocardiography was performed at 1.6±0.4 months after hospital discharge. The end point included sudden cardiac death, ventricular fibrillation and sustained ventricular tachycardia (SCD/VA)...

BACKGROUND: Chronic rhinosinusitis (CRS) is a commonly observed sequela after radiation therapy to the paranasal sinuses. The histopathologic features of radiation-induced CRS have yet to be determined and may have major implications in disease management. METHODS: A structured histopathology report was utilized to analyze sinus tissue removed during functional endoscopic sinus surgery (FESS). Histopathology variables, Lund-Mackay score (LMS), and 22-item Sino-Nasal Outcome Test (SNOT-22) scores were compared among patients with radiation-induced CRS (CRSr), CRS without nasal polyps (CRSsNP), and CRS with nasal polyps (CRSwNP)...

This study was conducted to determine the effects of 8-week administration of testosterone enanthate (TE) in conjunction with resistance training on thyroid hormones and lipid profiles. Sixty male adult Wistar rats were randomly divided into six groups: C: olive oil, RT: resistance training + olive oil, LD: TE (20 mg/kg), HD: TE (50 mg/kg), RT + LD: RT + TE (20 mg/kg), RT + HD: RT + TE (50 mg/kg). The RT consisted of climbing (5 reps/3 sets) a ladder carrying a load suspended from the tail. At the end, blood specimens were obtained from the orbital sinus and serum concentration of T4, T3, TSH and lipid profiles was determined...

Bacterial resistance is a growing phenomenon which led the scientific community to search for new therapeutic targets, such as biofilm. A bacterial biofilm is a surface-associated agglomerate of microorganisms embedded in a self-produced extracellular polymeric matrix made of polysaccharides, nucleic acids, and proteins. Scientific literature offers several reports on a biofilm's role in infections regarding various body districts. The presence of a bacterial biofilm is responsible for poor efficacy of antibiotic therapies along with bacterial infections in ear, nose, and throat (ENT) districts such as the oral cavity, ear, nasal cavities, and nasal sinuses...

We report a case of exogenous lipoid pneumonia from chronic, extranasal use of petrolatum ointment (Vicks VapoRub in this case) for nasal decongestion in a young woman, presenting with cough, dyspnea and fever. Exogenous Lipoid pneumonia is a rare condition, underdiagnosed and is more prevalent in adults. Usually asymptomatic and diagnosed while evaluating predisposed patients who become clinically unstable or an abnormal lung shadow or during evaluation of rhinobronchial allergy. It is rarely reported from chronic use of petrolatum ointment extranasally and was diagnosed by transbronchial biopsy in the present case...

BACKGROUND: Transsphenoidal surgery is the gold standard for pituitary adenoma resection. However, despite advances in microsurgical and endoscopic techniques, some pituitary adenomas can be challenging to cure. OBJECTIVE: To determine whether, in patients undergoing transsphenoidal surgery for pituitary adenoma, intraoperative ultrasound is a safe and effective technological adjunct. METHODS: The PubMed database was searched between January 1996 and January 2016 to identify relevant publications that (1) featured patients undergoing transsphenoidal surgery for pituitary adenoma, (2) used intraoperative ultrasound, and (3) reported on safety or effectiveness...

Atrial fibrillation (AF) is the most common sustained arrhythmia and across the developed nations, it contributes to increasing hospitalizations and healthcare burden. Several comorbidities and risk factors including hypertension, heart failure, obstructive sleep apnoea and obesity are known to play an important role in the initiation and perpetuation of AF and atrial stretch or dilatation may play a central mechanistic role. The impact of atrial stretch in the development of AF can vary dependent on the underlying disease...

Cardiac resynchronization therapy has emerged as the gold standard for heart failure patients with left ventricular systolic dysfunction and electrical dyssynchrony from an intrinsic intraventricular conduction delay or right ventricular pacing. However, the limits imposed by the coronary sinus venous anatomy restrict the applicability of the technology for many potential recipients. Furthermore, conventional resynchronization, by virtue of utilizing a single site of epicardial origin for left ventricular activation, is non-physiological...
