Prehospital Laryngeal Tube Airway Device Placement Resulting in Hypopharyngeal Perforation: A Case Report.

A 26-year-old female patient presented in cardiac arrest from presumed opioid overdose. An Ambu King LTS-D laryngeal device was placed by EMS providers for airway management during the resuscitation. There was no documented difficulty with placement and breath sounds and waveform capnography were consistent with appropriate placement.

Identifying characteristics and outcomes that are associated with fall-related fatalities: multi-year retrospective summary of fall deaths in older adults from 2005-2012.

Background: Fall-related deaths continue to be the leading cause of accidental deaths in the older adult (65+ year) population. However, many fall-related fatalities are unspecified and little is known about the fall characteristics and personal demographics at the time of the fall. Therefore, this report describes the characteristics, circumstances and injuries of falls that resulted in older adult deaths in one U.

One Wisconsin County's Experience With Fall-Related Mortality.

Background: Falls in Wisconsin account for 74.1% of all injury-related deaths for persons 65 years and older. This study describes the rate, demographics, and characteristics of fall-related mortality in one Wisconsin county over an 8-year period from 2005 to 2012.

Differential calcification of cusps and aortic wall of failed stented porcine bioprosthetic valves.

In this study, we examined separately calcification of cusps (C) and associated aortic wall (AW) of 38 (13 aortic and 25 mitral) porcine bioprosthetic heart valves explanted from 37 patients (ages 25-80 years, mean 59) for structural dysfunction, following 54-210 months (mean 125 months aortic, 119 months mitral). Valves were sectioned into C and corresponding AW components; calcification was assessed by atomic absorption spectroscopy for calcium and histologic examination. Overall, AW calcification was half that of C (33.

Laboratory investigation of deaths due to anaphylaxis.

To establish a useful laboratory protocol to investigate possible cases of fatal anaphylaxis, we measured mast-cell-derived tryptase levels and allergen-specific immunoglobulin E (IgE) antibody levels in sera obtained prior to or within 24 h after death from 19 anaphylaxis victims. Elevated serum tryptase levels (range = 12 ng/mL to 150 micrograms/mL) were found in nine of nine Hymenoptera sting fatalities, six of eight food-induced fatalities, and two of two reactions to diagnostic therapeutic agents. Tryptase levels were normal (less than 10 ng/mL) in 57 sequential sera obtained postmortem from six control patients.
