Atraumatic Clostridial myonecrosis: case report and literature review.

Clostridial myonecrosis (CM) is a rare, life-threatening infection that is most often associated with recent surgery or skeletal muscle trauma. It usually affects patients with some degree of underlying immunocompromise or vascular insufficiency. Occasionally, CM can occur at remote sites, with seeding from a gastrointestinal source in the setting of malignancy. We report a case of a 75-year-old man who developed rapidly progressive myonecrosis in the right shoulder, without prior trauma, caused by Clostridium septicum. On autopsy, this patient was found to have previously undiagnosed radiation colitis with ulcerations and abscess formation, secondary to recent prostate cancer radiation therapy. Although several case reports discuss CM in the setting of bowel malignancy, our case illustrates that non-malignant bowel inflammation may be a sufficient source for the infection. Clinical features of this uncommon disease are discussed, and the relevant literature is reviewed with regard to Clostridium septicum as an etiologic agent.

Efficient communication: assessment-oriented oral case presentation.

OBJECTIVE: To introduce and assess the time savings from and effectiveness of assessment-oriented (AO) oral case presentation as a model of interphysician communication. METHODS: This was a prospective, interventional study of all 10 on-site faculty and 36 residents in a postgraduate year 1 to 3 format emergency medicine residency training program. Residents were requested to perform all oral case presentations in either the traditional or AO formats. Presentations were timed, and residents and faculty rated essential measures of oral case presentation effectiveness: data content, expression of decision making, organization, and overall satisfaction. RESULTS: A total of 199 oral case presentations were sampled-112 traditional and 87 AO. Mean length of presentation for traditional presentations was 117 seconds versus 71 seconds for AO presentations (p < 0.001), a clinically significant difference, without significant differences in the essential measures of case presentation effectiveness. CONCLUSIONS: AO oral case presentation may provide a means for emergency medicine residents to "get to the point" and to communicate effectively and efficiently.

"Between me and the computer": increased detection of intimate partner violence using a computer questionnaire.

STUDY OBJECTIVE: The emergency department is a problem-focused environment in which routine screening for intimate partner violence (IPV) is difficult. We hypothesized that screening for IPV during computer-based health-risk assessment would be acceptable to patients and improve detection. METHODS: We performed a descriptive study of IPV data collected during a controlled trial of computer-based health promotion in an urban hospital ED. Patients received computer-generated health advice, and physicians received patient risk summaries. Outcomes were patient disclosure and physician documentation of IPV and associated risks. RESULTS: Two hundred forty-eight patients (69% female, 90% black, mean age 39 years) participated in a clinical trial of computer-based health promotion in the ED. Of 170 women, 53 (33%) disclosed emotional abuse, and 25 (15%) disclosed physical abuse. Of 78 men, 22 (29%) disclosed emotional abuse, and 5 (6%) disclosed physical abuse. Patients were also willing to self-report a history or concern of hurting someone close to them. This was true for 21 (14%) women and 15 (22%) men. Controlling for demographic factors, disclosures of victimization and perpetration were associated with multiple psychosocial risks. Computer screening resulted in chart documentation in 19 of 83 potential cases of IPV compared with 1 case documented in the group that received usual care. CONCLUSION: Providing an opportunity for patients to confidentially self-disclose IPV has the potential to supplement current screening efforts and to allow providers to focus on assessment, counseling, and referral for those at risk. However, further measures will be needed to ensure that information gathered through computer screening is adequately addressed during the acute care or follow-up visit.
