Palmar Soft Tissue Infection From Shewanella putrefaciens.

Shewanella putrefaciens, a gram-negative bacillus, ubiquitous in marine environments, is an opportunistic agent reported to cause rare human infection, most commonly in patients who are immunocompromised or who have a preexisting soft tissue defect. We present an immunocompetent, 40-year-old woman with a soft tissue infection of the left palm caused by S. putrefaciens. The patient's infection was complicated by the presence of retained foreign bodies, seashell fragments, from a traumatic fall. Following appropriate evaluation and surgical treatment, our patient experienced a successful outcome with no recurrence of infection or deficit in the affected hand. This case report complements the growing literature regarding morbidity attributed to S. putrefaciens infection.

Seven sins of humanitarian medicine.

The need for humanitarian assistance throughout the world is almost unlimited. Surgeons who go on humanitarian missions are definitely engaged in a noble cause. However, not infrequently, despite the best of intentions, errors are made in attempting to help others. The following are seven areas of concern: 1. Leaving a mess behind. 2. Failing to match technology to local needs and abilities. 3. Failing of non-governmental organizations (NGO's) to cooperate and help each other, and and accept help from military organizations. 4. Failing to have a follow-up plan. 5. Allowing politics, training, or other distracting goals to trump service, while representing the mission as "service". 6. Going where we are not wanted, or needed and/or being poor guests. 7. Doing the right thing for the wrong reason. The goal of this report is to discuss these potential problems, with ideas presented about how we might do humanitarian missions more effectively.

Acute pseudogout presenting as an exception to Musculoskeletal Infection Society criteria in total knee arthroplasty: a case report.

In this case, a 78-year-old female with no previous medical history of crystalline arthropathy presented with pain, effusion, and erythema about a total knee arthroplasty (TKA) performed 13 years prior. Implementation of a novel synovial fluid alpha-defensin assay ruled out periprosthetic joint infection (PJI) despite a positive 2018 Musculoskeletal Infection Society (MSIS) minor criteria score of 8 points, a significant diagnostic differentiation which prevented secondary invasive debridement or joint irrigation intervention. Confirmatory histologic study was positive for calcium pyrophosphate crystals, indicative of acute pseudogout inflammation rather than PJI or septic arthritis manifestation. The patient was then conservatively managed medically for a pseudogout flare and had no evidence of infection with normal physical exam and laboratory study at one- and two-years post treatment, respectively. Given the predominantly clinical nature of current PJI assessment in-clinic coupled with notable risks associated with aggressive re-intervention in the setting of suspected infection, critical need exists for the maturation of sensitive, reliable empiric measures which may assist in guiding orthopaedic surgeon evaluation of patients presenting with inflammatory symptomology around a previous surgical site. In this case, we conclude that patients with a negative alpha-defensin assay alongside crystalline arthropathy on histology may be cautiously yet successfully treated non-operatively despite clinical MSIS criteria concerning for PJI.

Development of a tongue-tie case definition in newborns using a Delphi survey: The NYU-Tongue-Tie Case Definition.

OBJECTIVE: The primary purpose of this study was to develop an operational definition of the oral condition of ankyloglossia (also called tongue-tie) that occurs in newborns (i.e., age birth-6 months) and that could consistently be used in research studies. STUDY DESIGN: This 4-round Delphi survey developed the consensus New York University-Tongue-Tie Case Definition (NYU-TTCD) by using a panel of ankyloglossia treatment experts. RESULTS: This tongue-tie case definition (TTCD) was carefully created in a step-wise manner from the bottom up by expert panelists over 4 rounds of inquiry. As a functioning case definition, it offers the diagnostician 2 separate pathways to identifying a newborn as being tongue tied. One pathway requires but a single pathognomonic anatomic feature, and the other pathway requires a single functional deficit accompanied by at least 2 of 12 other diagnostic items (functional, anatomic, or behavioral). CONCLUSIONS: This Delphi survey, as administered to a panel of ankyloglossia treatment experts, produced the first consensus case definition of tongue-tie for newborns (i.e., age birth-6 months) for use in epidemiologic research studies ranging from descriptive prevalence studies to clinical trials. Next-step studies should establish the validity, reliability, and utility of this novel NYU-TTCD case definition for epidemiologic and clinical purposes.

Outcomes After Operative and Nonoperative Treatment of Proximal Hamstring Avulsions: A Systematic Review and Meta-analysis.

BACKGROUND: No meta-analysis has compared outcomes of operative and nonoperative proximal hamstring avulsion treatment. PURPOSE: To compare outcomes of operative and nonoperative proximal hamstring avulsion treatment, including acute, chronic, partial, and complete repairs. STUDY DESIGN: Meta-analysis. METHODS: PubMed, CINAHL, SPORTdiscus, Cochrane Library, EMBASE, and Web of Science were searched up to July 2016. Three authors screened the studies and performed quality assessment using criteria from the Methodologic Index for Nonrandomized Studies. A best evidence synthesis was subsequently used. RESULTS: Twenty-four studies (795 proximal hamstring avulsions) were included. Twenty-two studies included proximal hamstring avulsion repairs; 1 study had proximal hamstring avulsion repairs and a control group of nonoperatively treated proximal hamstring avulsions; and 1 study had solely nonoperatively treated proximal hamstring avulsions. The majority of studies were of low methodological quality. Overall, repairs had significantly higher patient satisfaction (90.81% vs 52.94%), hamstring strength (85.01% vs 63.95%), Lower Extremity Functional Scale scores (72.77 vs 69.53), and single-legged hop test results (119.1 vs 56.62 cm) (all P < .001); complications occurred in 23.17% of cases. Compared with chronic repairs, acute avulsion repairs had greater patient satisfaction (95.48% vs 83.79%), less pain (1.07 vs 3.71), and greater strength (85.2% vs 82.8%), as well as better scores for the Lower Extremity Functional Scale (75.64 vs 71.5), UCLA activity scale (University of California, Los Angeles; 8.57 vs 8.10), and Single Assessment Numeric Evaluation (93.36 vs 86.50) (all P < .001). Compared with partial avulsion repairs, complete avulsion repairs had higher patient satisfaction (89.64% vs 81.35%, P < .001), less pain (1.87 vs 4.60, P < .001), and higher return to sport or preinjury activity level, but this was insignificant (81.43% vs 73.83%, P = .082). Partial avulsion repairs had better hamstring strength (86.04% vs 83.71%, P < .001) and endurance (107.13% vs 100.17%, P < .001). Complete repairs had significantly higher complication rates (29.38% vs 11.27%, P = .001). CONCLUSION: Proximal hamstring avulsion repair resulted in superior outcomes as compared with nonoperative treatment, although the complication rate was 23.17%. The nonoperative group was quite small, making a true comparison difficult. Acute repairs have better outcomes than do chronic repairs. Complete avulsion repairs had higher patient satisfaction, less pain, and a higher complication rate than partial avulsion repairs, although partial avulsion repairs had better hamstring strength and endurance. Studies of high methodological quality are lacking in terms of investigating the outcomes of proximal hamstring avulsion repairs.

Proposed educational objectives for hospital-based dentists during catastrophic events and disaster response.

The purpose of this project was to define education and training requirements for hospital-based dentists to efficiently and meaningfully participate in a hospital disaster response. Eight dental faculty with hospital-based training and/or military command and CBRNE (chemical, biological, radiological, nuclear, and explosive) expertise were recruited as an expert panel. A consensus set of recommended educational objectives for hospital-based dentists was established using the following process: 1) identify assumptions supported by all expert panelists, 2) determine current advanced dental educational training requirements, and 3) conduct additional training and literature review by various panelists and discussions with other content and systems experts. Using this three-step process, educational objectives that the development group believed necessary for hospital-based dentists to be effective in treatment or management roles in times of a catastrophic event were established. These educational objectives are categorized into five thematic areas: 1) disaster systems, 2) triage/medical assessment, 3) blast and burn injuries, 4) chemical agents, and 5) biological agents. Creation of training programs to help dentists acquire these educational objectives would benefit hospital-based dental training programs and strengthen hospital surge manpower needs. The proposed educational objectives are designed to stimulate discussion and debate among dental, medical, and public health professionals about the roles of dentists in meeting hospital surge manpower needs.

The European experience with vascular injuries.

The rich and diverse heritage of the management of vascular injuries in the 45 independent European countries prevents the authors from revealing a uniform picture of the European experience, but some trends are clearly emerging. In countries with a low incidence of penetrating trauma and increasing use of interventional vascular procedures, the proportion of iatrogenic vascular trauma exceeds 40% of all vascular injuries, whereas on other parts of the continent, armed conflicts are still a major cause of vascular trauma. National vascular registries, mostly in the Scandinavian countries, produce useful, nationwide data about vascular trauma and its management but suffer still from inadequate data collection. Despite a relatively low incidence of vascular trauma in most European countries, the results are satisfactory, probably in most cases because of active and early management by surgeons on call, whether with vascular training or not, treating all kinds of vascular surgical emergencies. In some countries, attempts at developing a trauma and emergency surgical specialty, including expertise in the management of vascular injuries, are on their way.

Triage: Principles and Pressures.

The aim of this paper is to review the art and science underpinning the application of effective triage. The paper also attempts to cut through the fog of confusion surrounding the topic and to point a way towards a generally-agreed unified approach. Triage needs to be understood in the context of the environment in which it is applied, and the paper deals with this in some detail.
