Pityriasis Rosea (PR) and labyrinthitis are most commonly caused by viral infections. PR presents with a characteristic rash while labyrinthitis presents with vertigo, tinnitus and hearing loss. ⋯ Human Herpes Virus (HHV) 6 and 7, are common infections in childhood, and their reactivation causes Pityriasis Rosea. But these viruses are not known to have any involvement with the inner ear or the 8th cranial nerve (CN).

Case Reports
An unusual presentation of pulmonary artery sarcoma: Several pseudoaneurysms with massive hemoptysis.
A 53-year-old woman was admitted to the emergency department with sudden onset of massive hemoptysis. She had previous history of dyspnea and cough for two months. She had no history of chronic disease, smoking, or use of anticoagulant and antiplatelet drugs. ⋯ Although hemoptysis is an uncommon presentation for patients with PAS, accompanied pseudoaneurysms were the main reason for massive hemoptysis. Differentiation of PAS from bland thromboembolism could be challenging on CT. Herein reported case provides an additional imaging feature that may utilize differentiating pulmonary artery sarcoma from bland thrombus.

The emergency department (ED) is responsible for managing a variety of acute illnesses including undifferentiated shock. A newer less recognized syndrome termed BRASH - bradycardia, renal failure, AV-node blockers, shock and hyperkalemia - is a cycle of synergy between hyperkalemia and AV-blockade that can result in shock. This entity is more common amongst the elderly, considering polypharmacy and co-morbid diseases. ⋯ Herein, we report a case of anaphylaxis induced BRASH syndrome occurring in an elderly diabetic man. The EP should be aware of this unique presentation of BRASH. It was concluded that the patient's anaphylaxis, caused hypovolemia, coupled with polypharmacy, and physiological stress, precipitated this severe form of shock and multi-organ system failure.

Multicenter Study Observational Study
Association of response time interval with neurological outcomes after out-of-hospital cardiac arrest according to bystander CPR.
This study intended to find out how association between response time interval (RTI) and good neurological outcome is affected by bystander CPR. We hypothesized that bystander CPR will ensure positive effect in relationship between RTI and clinical outcome. ⋯ As response time interval increased, slower deterioration of good neurological outcome and survival discharge was shown in cardiac arrest patients with bystander CPR performed. If bystander CPR is provided, RTI time range showing significant neurological outcome and survival improvement seems to be relatively lengthened.

Observational Study
Predictive factors for acute brain lesions on magnetic resonance imaging in acute carbon monoxide poisoning.
Acute brain lesions on diffusion-weighted-magnetic resonance imaging (MRI) after acute carbon monoxide (CO) poisoning were associated with delayed neurological sequelae. This study was conducted to identify the risk factors associated with acute brain lesions on MRI after acute CO poisoning and to help select patients who need acute-phase brain MRI after acute CO poisoning in the emergency department (ED). ⋯ Acute-phase brain MRI in acute CO poisoning can be considered for patients who present at the ED with a GCS score <9 or troponin-I level >0.105 ng/mL.
