Myocardial stunning occurs when myocardial contractile function does not instantaneously recover after reperfusion.[1] It is often studied in nuclear stress tests through changes in left ventricular ejection fraction (LVEF) and end-diastolic dysfunction post-stress. He underwent a one-day myocardial perfusion SPECT with 8mCi Tc99m tetrofosmin injected at rest and 24mCi Tc99m tetrofosmin injected at peak stress. [Extracted from the article]

Biological disasters can be natural, accidental, or intentional. Biological threats have made a lasting impact on civilization. This review focuses on agents of clinical significance, bioterrorism, and national security, specifically Category A agents (anthrax, botulism, plague, tularemia, and smallpox), as well as briefly discusses other naturally emerging infections of public health significance, Ebola virus (also a Category A agent) and Zika virus. The role of pharmacists in disaster preparedness and disaster response is multifaceted and important. Their expertise includes clinical knowledge, which can aid in drug information consultation, patient‐specific treatment decision making, and development of local treatment plans. To fulfill this role, pharmacists must have a comprehensive understanding of medical countermeasures for these significant biological threats across all health care settings. New and reemerging infectious disease threats will continue to challenge the world. Pharmacists will be at the forefront of preparedness and response, sharing knowledge and clinical expertise with responders, official decision makers, and the general public. [ABSTRACT FROM AUTHOR]

A 72-year-old woman presented to the emergency department with shortness of breath, diffuse swelling and a haemoglobin of 4.2 g/dl. Her history was notable for an unusual necrotic occipital neck mass that had begun to enlarge and intermittently bleed over the past year. The patient was initially unable to tolerate a CT scan because of the neck mass, and care was further complicated by extended boarding for more than 24 h in the emergency department. Initial fevers were attributed to blood transfusion, but she subsequently developed septic shock and disseminated intravascular coagulation from Escherichia coli bacteraemia, which led to anuric renal failure requiring haemodialysis. When the CT was performed, it revealed an obstructing ureteric stone which was the source of her infection, not the neck mass as had been assumed. This case underscores the importance of maintaining a broad and impartial differential diagnosis. [ABSTRACT FROM AUTHOR]
