Comparative Study
Clinical evaluation compared to the pulse indicator continuous cardiac output system in the hemodynamic assessment of critically ill patients.
The objective was to assess the effects of pulse indicator continuous cardiac output catheterization on the management of critically ill patients and the alteration of therapy in intensive care units. ⋯ The hemodynamic variables obtained from pulse indicator continuous cardiac output catheterization improved the accuracy of bedside evaluations and led to alterations in therapeutic plans, particularly among the moderately ill patients with hypotension or unknown diagnoses.

The aims of this study were (a) to determine the prehospital prevalence of electrocardiographic (ECG) signs of acute myocardial ischemia in patients with suspected acute coronary syndrome and (b) to describe the relationships between the various ECG patterns and the diagnosis of acute myocardial infarction (AMI) and outcomes. ⋯ Among patients with a clinical suspicion of AMI in the prehospital setting, the prevalence of ECG signs suggesting AMI was low, as was the ability to identify AMI patients using ECG findings only. We therefore need better instruments in the prehospital triage of patients with acute chest pain.

The objective of this study was to describe patterns of older adult patient visits to emergency departments (EDs) for self-harm and suicide-related injuries. ⋯ Effort is needed to better integrate and deliver suicide screening and support services in the ED, while also connecting at-risk older adults with mental health services before and after the ED encounter.

Massive wasp envenomation can cause not only severe immediate allergic reactions and anaphylaxis but also severe delayed toxin-mediated systemic reactions, including hemolysis, coagulopathy, rhabdomyolysis, acute renal failure, and hepatotoxicity. However, reports of the latter type of reactions are rare. The subject of this case report, a 66-year-old man, was stung more than 30 times during an attack by wasps. ⋯ Immediately after diagnosis, an emergency laparotomy was performed. Nonocclusive mesenteric ischemia was finally diagnosed via a histologic examination of the resected small bowel. We present the first case report of nonocclusive mesenteric ischemia consequent to wasp stings.

Physicians need to consider a broad differential diagnosis when evaluating a patient presenting with a suspected stroke. The rates of overdiagnosis of stroke in studies of consecutive patients vary from 19% to 31%. The two most common stroke mimics are hypoglycemia and seizure, but several etiologies have been reported. We reported the case of a 41-year-old patient presenting to the emergency department with aphasia and right-side hemiparesis, initially suspected to have stroke and finally diagnosed of varicella-zoster encephalitis.
