BACKGROUND: Kounis syndrome corresponds to the occurrence of myocardial injury following an allergic insult. This syndrome is infrequent, and is not well known. In consequence, it is usually misdiagnosed leading to inappropriate treatment. The current literature is limited to case studies and there are no international recommendations concerning this topic. CASE PRESENTATION: We discussed, through two case reports, the clinical presentation and the management of a 60-year-old North African man and a 45-year-old North African man presenting with chest pain suggesting acute coronary syndrome following anaphylactic reaction...

REVIEW
Boulos S Nassar, Richard Kerber
Cardiac arrest continues to represent a public health burden with most patients having dismal outcomes. Cardiopulmonary resuscitation (CPR) is a complex set of interventions requiring leadership, coordination, and best practices. Despite the widespread adoption of new evidence in various guidelines, the provision of CPR remains variable with poor adherence to published recommendations. Key steps health care systems can take to enhance the quality of CPR and, potentially, to improve outcomes, include optimizing chest compressions; avoiding hyperventilation; encouraging intraosseus access, and monitoring capnography...

BACKGROUND CONTEXT: Previous studies have suggested pulmonary complications are common among patients undergoing fixation for traumatic spine fractures. This leads to prolonged hospital stay, worse functional outcomes, and increased economic burden. However, only limited prognostic information exists regarding which patients are at greatest risk for pulmonary complications. PURPOSE: To identify factors predictive of perioperative pulmonary complications in patients undergoing fixation of spine fractures...

The purpose of cardiopulmonary resuscitation after sudden cardiac arrest is to restore minimal blood flow to provide oxygen to the brain and other vital organs. Chest compressions and external defibrillation are the first line for circulatory support. Although early defibrillation is the main factor influencing survival, cardiopulmonary resuscitation must be characterized by high-quality external chest compressions. Unfortunately, the performance of manual chest compressions decreases during time and in hostile conditions...

Patients with mechanical aortic valves are generally contraindicated for left ventricular assist device (LVAD) insertion because the prosthetic valve often becomes fixed in closed position. A 41-year-old woman with mechanical aortic valve prosthesis experienced sudden chest pain and developed cardiogenic shock. A paracorporeal pulsatile LVAD and a monopivot centrifugal pump as a right VAD (RVAD) were implanted. The mechanical aortic valve was intentionally left in place. Soon after the operation, LVAD support was discontinued daily for few seconds to allow the mechanical aortic valve to open and to avoid thrombus formation...

Respiratory muscle weakness and chest wall abnormalities in neuromuscular diseases (NMD) may lead to decreased pulmonary volumes. We assessed the reversibility of vital capacity (VC) reduction with mechanical In-Exsufflation (MI-E). We evaluated the effects of positive inspiratory and negative expiratory pressures on spirometric variables under passive (without patients' participation) and active (with active participation) application in 47 NMD patients. VC, inspiratory capacity (IC), expiratory reserve volume (ERV) were measured during maneuvers without and with MI-E assistance, delivering inspiratory assistance (+40cmH2O), expiratory assistance (-40cmH2O) and both (±40cmH2O)...

BACKGROUND: Patients with microvascular angina (exertional angina, positive exercise tests and normal coronary arteriograms) usually have a reduced coronary blood flow reserve. Neuropeptide Y (NPY) is a potent endogenous vasoconstrictor involved in modulation of coronary vasomotor tone and may play a role in microvascular angina. METHODS: We compared the effects of NPY (0.2-1.0pmol/kg, intracoronary) on the vasomotor response of proximal and distal segments of the coronary arteries in 7 patients with microvascular angina, 9 with chronic stable angina, and 9 control individuals...
