Necrotizing fasciitis is characterized by a rapidly progressing necrosis of subcutaneous fat and fascia that rarely occurs in head and neck. It can be life threatening in the case of late diagnosis and antibiotic therapy and without surgical intervention. It is caused by group A streptococci or by a synergistic combination of aerobe and anaerobe microorganisms and bacterial synergy is an import...

BACKGROUND Cardiac involvement in patients with polymyositis is well-documented and includes myocarditis, coronary arteritis, pericarditis, valvular dysfunction and arrhythmias. CASE REPORT There are only few reports of acute myocarditis in patients with polymyositis and, although it usually follows a chronic, mild course, it may occasionally become life-threatening. We describe the case of a...

AIM To determine the accuracy of international warfarin pharmacogenetic algorithms developed on large multiethnic cohorts (comprising more than 1000 subjects) to predict therapeutic warfarin doses in Turkish patients. MATERIALS & METHODS We investigated two Turkish warfarin-treated cohorts: patients with no history of hemorrhagic or thromboembolic event and patients with major and life-threat...

Varicella-zoster virus (VZV) infection can rarely lead to serious cardiac complications and life-threatening arrhythmias. We present a case of a 46-year-old male patient who developed VZV myocarditis and presented with recurrent syncopal episodes followed by a cardiac arrest. He had a further collapse eight years later, and cardiac magnetic resonance imaging (MRI) demonstrated mild mid-wall bas...

In visual search, an angry face in a crowd "pops out" unlike a happy or a neutral face. This "anger superiority effect" conflicts with views of visual perception holding that complex stimulus contents cannot be detected without focused top-down attention. Implicit visual processing of threatening changes was studied by recording event-related potentials (ERPs) using facial stimuli using the cha...

There is preliminary evidence to suggest that worry is associated with dysregulated emotion processing resulting from sustained attention to emotional versus neutral stimuli; however, this hypothesis has not been directly tested in prior research. Therefore, the current study used the event-related late positive potential (LPP) to directly examine if high levels of trait worry moderate sustaine...

The current study examined whether the weapon focus effect could be accounted for in terms of stimulus novelty. Participants viewed a slideshow of a simulated event while attending to a secondary task. In the critical slide, the target was shown holding a threatening object (weapon condition), a novel object (unusual condition) or a neutral object (control condition). Reaction times on the seco...

Both dynamic non-emotional stimuli (moving dots or digits) and danger-related static stimuli have previously shown to capture attention. This study explored whether the combination of the two factors (i.e., threatening moving stimuli), frequent in natural situations, enhances attentional capture. To this end, static and moving distractors containing emotionally negative and non-negative informa...
