Fine particulate matter-sudden death association modified by ventricular hypertrophy and inflammation: a case-crossover study.

Background: Sudden death accounts for approximately 10% of deaths among working-age adults and is associated with poor air quality. Objectives: To identify high-risk groups and potential modifiers and mediators of risk, we explored previously established associations between fine particulate matter (PM) and sudden death stratified by potential risk factors.

Methods: Sudden death victims in Wake County, NC, from 1 March 2013 to 28 February 2015 were identified by screening Emergency Medical Systems reports and adjudicated ( = 399).

Diffuse lymphadenopathy and fever without a rash: an atypical presentation of secondary syphilis.

A woman in her 30s presented to the emergency department with 4 days of fever, headache and back pain. The patient was admitted for pain control, inability to tolerate oral intake and intravenous antibiotics for presumed diagnosis of pyelonephritis. Following admission, CT of the abdomen/pelvis showed multiple prominent pelvic and inguinal lymph nodes, and the patient was noted to have anterior and posterior cervical and submandibular lymphadenopathy on examination.
