ABSTRACT
Summary: Background. Kounis syndrome (KS) is defined as a rare cause of an acute coronary syndrome associated with systemic allergic reactions. To establish the prevalence of KS among the patients with diagnosis of anaphylaxis, we described clinical features, cardiological and allergological outcomes of patients evaluated in our allergy outpatient clinic. Methods. A retrospective study was carried out in the Allergy Unit of Novara hospital, from January 2008 to March 2020. Skin tests and in vitro tests were performed with suspected etiological agents. Results. We found 9 adults with KS (2%) out of 444 subjects who had experienced anaphylactic reactions (4/9 to Hymenoptera stings, 5/9 to drugs). Conclusions. The present study highlights the importance of suspicion of KS that appears not so uncommon in patients with anaphylaxis. KS seems to be a rare disease because unrecognized in diagnosis of anaphylaxis.

AIM: The aim of the study was to detect early predictors of neurological recovery and evaluate one year survival related to neurological status at discharge in patients (pts) admitted after out of hospital cardiac arrest (OHCA). METHODS: Sixty-three consecutive pts with OHCA from any cardiac cause, admitted to our cardiac intensive care unit, were classified according to survival and cerebral performance category (CPC) scale from 1 to 4 at hospital discharge. Pre-hospital and emergency room (ER) variables were analyzed to identify early predictors of neurological recovery as defined CPC=1-2. RESULTS: Overall in-hospital survival was 60%. Sixty-eight and 32% of survivors were classified as CPC 1-2 and CPC 3-4 respectively. During one year follow-up 96% of patients classified as CPC 1-2 survived and 100% of CPC 3-4 died. Emergency crew witnessing, performance of cardio pulmonary resuscitation (CPR) by witnesses, the call for chest pain, no history of heart disease and a Glasgow coma scale (GCS) of ≥9 on arrival to the ER, were more frequent in patients classified as CPC 1-2 and times from "OHCA to return of spontaneous circulation (ROSC)", from "emergency medical system (EMS) arrival to ROSC" and "first DC shock to ROSC" were also significantly shorter in these patients. The time of first DC shock to ROSC in pts who presented with rhythm in ventricular fibrillation and the time from OHCA to ROSC in pts with witnessed OHCA were an independent predictors of neurological recovery. CONCLUSION: Forty-one percent of pts admitted to our tertiary centre after OHCA were discharged with CPC 1-2 and at one year follow-up 96% of these were alive, while all pts classified as CPC 3-4 died. Easily documented information such as the time from OHCA to ROSC and the time of first shock to ROSC are early independent predictors of neurological recovery.

Recently, the feasibility and safety of percutaneous aortic valve replacement (PAVR) have been reported in the treatment of degenerative aortic valve stenosis in patients at high-risk for surgical aortic valve replacement (AVR). However, so far this therapy has been limited to patients with severe stenosis of the native valve. We report the case of an 84 year old patient with severe aortic regurgitation caused by infective endocarditis who was successfully treated by implantation of a CoreValve (CoreValve Inc, Irvine. Calif) prosthesis with a totally percutaneous approach.
