Rapidly fatal bacteremic pneumonia caused by Klebsiella pneumoniae with K1 hypermucoviscosity phenotype in a previously healthy young man receiving levofloxacin treatment.

Fatal bacteremic Klebsiella pneumoniae pneumonia is commonly encountered in alcoholic and diabetic patients. This report describes a previously healthy young man with rapidly fatal bacteremic pneumonia caused by K. pneumoniae serotype K1, complicated by septic shock and multiple organ dysfunction.

Video-recording and time-motion analyses of manual versus mechanical cardiopulmonary resuscitation during ambulance transport.

Introduction: The quality of cardiopulmonary resuscitation (CPR) plays a crucial role in saving lives from out-of-hospital cardiac arrest (OHCA). Previous studies have identified sub-optimal CPR quality in the prehospital settings, but the causes leading to such deficiencies were not fully elucidated.

Objective: This prospective study was conducted to identify operator- and ambulance-related factors affecting CPR quality during ambulance transport; and to assess the effectiveness of mechanical CPR device in such environment.

Appendiceal outer diameter as an indicator for differentiating appendiceal mucocele from appendicitis.

Background: Patients with appendiceal mucocele (AM) commonly present with features indicative of acute appendicitis. In emergency departments, accurate preoperative diagnosis is crucial to prompt appropriate treatment. This study investigates the clinical and sonographic characteristics of AM, which may prove useful in preoperatively differentiating AM from appendicitis.
