Abstract Diagnostic testing is an integral component of patient evaluation in the emergency department ( ED ). Emergency clinicians frequently use diagnostic testing to more confidently exclude “worst‐case” diagnoses rather than to determine the most likely etiology for a presenting complaint. Increased utilization of diagnostic testing has not been associated with reductions in disease‐related mortality but has led to increased overall healthcare costs and other unintended consequences (e.g., incidental findings requiring further workup, unnecessary exposure to ionizing radiation or potentially nephrotoxic contrast). Shared decision making ( SDM ) presents an opportunity for clinicians to discuss the benefits and harms associated with diagnostic testing with patients to more closely tailor testing to patient risk. This article introduces the challenges and opportunities associated with incorporating SDM into emergency care by summarizing the conclusions of the diagnostic testing group at the 2016 Academic Emergency Medicine Consensus Conference on SDM . Three primary domains emerged: 1) characteristics of a condition or test appropriate for SDM , 2) critical elements of and potential barriers to SDM discussions on diagnostic testing, and 3) financial aspects of SDM applied to diagnostic testing. The most critical research questions to improve engagement of patients in their acute care diagnostic decisions were determined by consensus.

Background. Although alcohol and tobacco use are known risk factors for development of squamous cell carcinoma in the head and neck, human papillomavirus (HPV) has been increasingly associated with this group of cancers. We describe the case of a married couple who presented with HPV-positive oropharynx squamous cell carcinoma within two months of each other.Methods. Tumor biopsies were positive for p16 and high-risk HPV in both patients. Sanger sequencing showed a nearly identical HPV16 strain in both patients. Both patients received chemoradiation, and one patient also underwent transoral robotic tongue base resection with bilateral neck dissection.Results. Both patients showed no evidence of recurrent disease on follow-up PET imaging.Conclusions. New head and neck symptoms should be promptly evaluated in the partner of a patient with known HPV-positive oropharynx cancer. This case expands the limited current literature on concurrent presentation of HPV-positive oropharynx squamous cell carcinoma in couples.

ABSTRACT Mycobacterium terrae complex has been recognized as a cause of tenosynovitis, with M. terrae and Mycobacterium nonchromogenicum reported as the primary etiologic pathogens. The molecular taxonomy of the M. terrae complex causing tenosynovitis has not been established despite approximately 50 previously reported cases. We evaluated 26 isolates of the M. terrae complex associated with tenosynovitis or osteomyelitis recovered between 1984 and 2014 from 13 states, including 5 isolates reported in 1991 as M. nonchromogenicum by nonmolecular methods. The isolates belonged to three validated species, one new proposed species, and two novel related strains. The majority of isolates (20/26, or 77%) belonged to two recently described species: Mycobacterium arupense (10 isolates, or 38%) and Mycobacterium heraklionense (10 isolates, or 38%). Three isolates (12%) had 100% sequence identity to each other by 16S rRNA and 99.3 to 100% identity by rpoB gene region V sequencing and represent a previously undescribed species within the M. terrae complex. There were no isolates of M. terrae or M. nonchromogenicum , including among the five isolates reported in 1991. The 26 isolates were susceptible to clarithromycin (100%), rifabutin (100%), ethambutol (92%), and sulfamethoxazole or trimethoprim-sulfamethoxazole (70%). The current study suggests that M. arupense , M. heraklionense , and a newly proposed species (“ M. virginiense ” sp. nov.; proposed type strain MO-233 [DSM 100883, CIP 110918]) within the M. terrae complex are the major causes of tenosynovitis and osteomyelitis in the United States, with little change over 20 years. Species identification within this complex requires sequencing methods.

Introduction: Our study assesses the utility of telemetry in identifying decompensation in patients with documented cardiopulmonary arrest. Methods: A retrospective review of inpatients who experienced a cardiopulmonary arrest from May 1, 2008, until June 30, 2014, was performed. Telemetry records 24 hours prior to and immediately preceding cardiopulmonary arrest were reviewed. Patient subanalyses based on clinical demographics were made as well as analyses of survival comparing patients with identifiable rhythm changes in telemetry to those without. Results: Of 242 patients included in the study, 75 (31.0%) and 110 (45.5%) experienced telemetry changes at the 24-hour and immediately preceding time periods, respectively. Of the telemetry changes, the majority were classified as nonmalignant (n = 50, 66.7% and n = 66, 55.5% at 24 hours prior and immediately preceding, respectively). There was no difference in telemetry changes between intensive care unit (ICU) and non-ICU patients and among patients stratified according to the American Heart Association telemetry indications. There was no difference in survival when comparing patients with telemetry changes immediately preceding and at 24 hours prior to an event (n = 30, 27.3% and n = 15, 20.0%) to those without telemetry changes during the same periods (n = 27, 20.5% and n = 42, 25.2%; P = .22 and .39). Conclusion: Telemetry has limited utility in predicting clinical decompensation in the inpatient setting.

Objectives/HypothesisWe sought to analyze key factors that influence the management of lateral skull base defects and implement an algorithm to improve outcomes of reconstruction.Study DesignRetrospective chart review.SettingSingle tertiary academic referral center.MethodsAdults who underwent temporal bone resection were included. Variables included tumor characteristics, ablative procedure, reconstructive method, and wound complications.ResultsSeventy‐one patients were studied. Lateral temporal bone resection was performed in 55 patients (77%), subtotal temporal bone resection in 14 (20%), and total petrosectomy in two (3%). Primary closure was achieved in 46 patients (35%), with rotational muscle flaps in 21 (46%). The pectoralis major myocutaneous flap (PMMF) was used in nine patients (13%) without major complications. Single‐stage free tissue transfer was undertaken in 10 patients (14%) with no flap failures. Primary closure was achieved in 16 of 32 of previously untreated cases (50%) compared to nine of 39 cases of previously treated disease (23%) (P = 0.03). Pedicled or free flaps were used in 18 of 39 cases of previously treated disease (46%) compared to three of 32 previously untreated cases (9%) (P < 0.001). Pedicled or free flaps were used in 13 of 22 cases (59%) in which partial or total auriculectomy was performed, whereas primary closure was achieved in 39 of 49 cases (80%) in which the pinna was preserved (P < 0.001).ConclusionAdvanced tumors that require adjuvant therapy, revision cases for recurrent disease, and cases involving auriculectomy warrant free flap or PMMF reconstruction, with the latter preferred in poor free flap candidates.Level of Evidence4.

The authors describe transient apical thickening mimicking apical hypertrophic cardiomyopathy following apical ballooning syndrome. These findings are observed on multimodality cardiac imaging and appear to constitute a novel entity. Possible pathophysiologic mechanisms are explored.
