[Territorial emergency: physician or nurse?]. / Emergenza territoriale: medico o infermiere?

This study was conceived to assess a pattern of Italian prehospital critical care team, especially referring to the advanced life support (ALS) rescue team. Function and management of ALS rescue team and its relationship with other members of the emergency medical system (intra hospital physician, basic life support team, general practitioner) are analysed; stress is laidon the knowledge, the background and the complexity of the emergency procedures. The benefit of 2 major prehospital options of the ALS team, composed by 1 physician and 1 nurse staffing or by 2 trained nurse staffing, is discussed; the importance of educational programs for ambulance teams, a comparison of cost-effectiveness and the number of emergency teams availability is underlined. The authors, finally emphasize the advantages of a territorial coverage with an integrated system of ambulances staffed with specially trained rescuers or technicians, ambulances with rescuers and nurses, and ALS teams staffed with emergency physician and 1 nurse (integrated or not with ambulances with 2 trained nurses), being perfectly capable to face up any background in pre-hospital emergency medicine setting.

[Severe infection from invasive beta-hemolytic streptococcus group A. Three cases of toxic shock observed in resuscitation]. / Infezioni invasive gravi da streptococco beta emolitico di gruppo A. A proposito di 3 casi di shock tossiemico osservati in rianimazione.

Group A streptococci (GAS) may cause a variety of infections, some of which are severe and may be life-threatening. Patients affected by severe invasive GAS infections may develop, early in the course of the infection, a syndrome characterized by circulatory insufficiency with multiple organ failure: Streptococcal Toxic Shock-Like syndrome (Strep-TSLS). The presence of shock and organ failure differentiate it from other types of invasive GAS infections. Three cases patients presenting with the Strep-TSLS, over a period of 16 months in our multidisciplinary 10-bed ICU are described. The Strep-TSLS was of nosocomial origin in the first case, due to poststernotomy wound infection, caused from erysipela in the second patient, and associated to a puerperal sepsis in the third case, respectively. In this small series the primary sources of streptococcal infection associated with the syndrome are confirmed to be in soft tissues and skin. One patient died early after the admission to the ICU, whereas the other two patients completely recovered with appropriate antibiotic and supportive treatment although early diagnosis and radical operative debridement may have been conclusive in one case. All 3 observed cases fulfilled the consensus case definition of "certain case of Strep-TSLS", whose criteria have been recently revised.
