ABSTRACT
To better connect non-emergent 911 callers to appropriate care, Washington, DC, routed low-acuity callers to nurses. Nurses could provide non-emergent transportation to a health centre, recommend self-care or return callers to the traditional 911 system. Over about one year, 6,053 callers were randomized (1:1) to receive a business-as-usual response (ncontrol = 3,023) or further triage (ntreatment = 3,030). We report on seven of nine outcomes, which were pre-registered ( https://osf.io/xderw ). The proportion of calls resulting in an ambulance dispatch dropped from 97% to 56% (ß = -1.216 (-1.324, -1.108), P < 0.001), and those resulting in an ambulance transport dropped from 73% to 45% (ß = -3.376 (-3.615, -3.137), P < 0.001). Among those callers who were Medicaid beneficiaries, within 24 hours, the proportion of calls resulting in an emergency department visit for issues classified as non-emergent or primary care physician (PCP) treatable dropped from 29.5% to 25.1% (ß = -0.230 (-0.391, -0.069), P < 0.001), and the proportion resulting in the caller visiting a PCP rose from 2.5% to 8.2% (ß = 1.252 (0.889, 1.615), P < 0.001). Over the longer time span of six months, we failed to detect evidence of impacts on emergency department visits, PCP visits or Medicaid expenditures. From a safety perspective, 13 callers randomized to treatment were eventually diagnosed with a time-sensitive illness, all of whom were quickly triaged to an ambulance response. These short-term effects suggest that nurse-led triage of non-emergent calls can safely connect callers to more appropriate, timely care.
ABSTRACT
BACKGROUND: A 30-year-old immunocompetent male with an unremarkable medical history presented with 2 months of lower abdominal bloating and loose, bloody, mucoid bowel movements. He was clinically suspected to have IBD. Due to the progression of his symptoms, he ultimately required hospitalization for further investigation and care. INVESTIGATIONS: Full medical history and physical examination, routine blood analyses, stool studies, hepatitis serologic tests, abdominal CT, colonoscopy, PCR analysis and light microscopy and immunoperoxidase staining of colonic biopsy samples. DIAGNOSIS: Epstein-Barr virus (EBV)-associated lymphoproliferative disorder with diffuse colonic involvement (EBV colitis) in an immunocompetent adult. MANAGEMENT: Inpatient supportive care.

The prozone phenomenon in syphilis testing refers to a false negative response resulting from overwhelming antibody titers which interfere with the proper formation of the antigen-antibody lattice network necessary to visualize a positive flocculation test. This prozone effect in syphilis testing can be expected in cases of disproportionately high antibody titers, such as secondary syphilis, or with human immunodeficiency virus (HIV) coinfection. Clinicians need to remain familiar with the protean manifestations of syphilis to be able to exclude the prozone phenomenon.

Primary human immunodeficiency virus type 1 (HIV-1) infection (acute retroviral syndrome) has been well characterized as a mononucleosis-like illness. Manifestations of HIV-1 infection such as pharyngitis, fever, morbilliform rash, myalgias, arthralgias, nausea, headache, emesis, and lymphadenopathy have been reported. Acute rhabdomyolysis has been reported as part of the acute retroviral syndrome on 11 different occasions. We report the case of a primary HIV-1 infection with acute rhabdomyolysis and review critically the other case reports.
