ABSTRACT
INTRODUCTION: Early identification of sepsis is critical as early treatment improves outcomes. We sought to identify threshold values of secretory phospholipase A2 (sPLA2)-IIA that predict sepsis and bacterial infection compared to nonseptic controls in an emergency department (ED) population. MATERIALS AND METHODS: This is a prospective cohort of consenting adult patients who met two or more systemic inflammatory response syndrome (SIRS) criteria with clinical diagnosis of infectious source likely (septic patients). Controls were nonseptic consenting adults undergoing blood draw for other ED indications. Both groups had blood drawn, blind-coded, and sent to an outside laboratory for quantitative analysis of sPLA2-IIA levels. The study investigators reviewed patients' inpatient medical record for laboratory, imaging, and microbiology results, as well as clinical course. RESULTS: sPLA2-IIA levels were significantly lower in control patients as compared to septic patients (median = 0 ng/ml [interquartile range (IQR): 0-6.5] versus median = 123 ng/ml [IQR 44-507.75]; P < 0.0001). SPLA2-IIA levels were higher in patients with confirmed source (n = 28 patients, median = 186 ng/ml, 95% confidence interval = 115.1-516.8) as compared to those with no source identified or a viral source (n = 17, median = 68 ng/ml, 95% confidence interval = 38.1-122.7; P = 0.04). Using a cutoff value of 25 ng/ml, sPLA2-IIA had a sensitivity of 86.7% (confidence interval 72.5-94.5) and a specificity of 91.1% (confidence interval 77.9-97.1) in detecting sepsis. CONCLUSIONS: sPLA2-IIA shows potential as a biomarker distinguishing sepsis from other disease entities. Further study is warranted to identify predictive value of trends in sPLA-IIA during disease course in septic patients.
ABSTRACT
Annular lichenoid dermatitis (ALDY) is a rare dermatosis that is most often seen in children and young adults and is characterized by annular patches with raised borders, most frequently on the trunk and the groin. A distinct lichenoid tissue reaction involving the base of the rete, resulting in squared-off rete ridges, helps to differentiate this from other lichenoid dermatoses and mycosis fungoides (MF). Herein, we report an additional case of this condition in a 7-year-boy, whose biopsy exhibited the typical quadrangular rete alteration and also contained distinct aggregates of CD8+ lymphocytes, Langerhans cells and colloid bodies within the involved rete. A literature review with emphasis on the clinical and histopathological differential diagnosis reveals additional clinical features of ALDY to potentially help differentiate this entity from annular presentations of mycosis fungoides.

Although uncommon, medical emergencies do occur in the dental office setting. This article describes the development and implementation of an office-based emergencies course for third-year dental students. The course reviews the basic management of selected medical emergencies. Background information is provided that further highlights the importance of proper training to manage medical emergencies in the dental office. Details regarding course development, implementation, logistics, and teaching points are highlighted. The article provides a starting point from which dental educators can modify and adapt this course and its objectives to fit their needs or resources. This is a timely topic that should benefit both dental students and dental educators.

We describe the development and implementation of an office-based emergencies course for podiatric medical students. The program included a didactic session along with clinical skills stations incorporating task trainers, high-fidelity simulators, and a standardized patient. We tailored the course to the level of the junior podiatric medical student. The primary goal of this program was to provide a review on how to handle selected office-based medical emergencies. This course focused on complications of common chronic medical conditions, such as asthma, chronic obstructive pulmonary disease, diabetes, and hypertension, along with other unexpected emergencies, such as altered mental status, seizure, and syncope. In developing such a course, it is important to keep in mind the level of the learner and resources such as faculty availability and the facilities available for teaching.

Evaluating the adolescent with a genital lesion requires a thorough knowledge of the common and less-common STDs that cause genital findings. A thoughtful history and complete physical examination are always in order, as is testing for a particular suspected STD and for coexisting STDs, especially HIV.

We investigated the characteristics of lymphocytes propagated from biopsies of the mesenteric lymph nodes, liver, and ileum of a human multivisceral allograft in order to provide functional evidence for the presence or absence of rejection and graft-versus-host disease (GVHD). The recipient was a 39-month-old girl with secretory diarrhea due to microvillus inclusion disease and end-stage liver disease secondary to prolonged parenteral nutrition. She developed a multifocal posttransplant lymphoproliferative disorder (PTLD) and died 37 days after transplantation. Four pairs of sequential mesenteric lymph node and liver biopsies (13, 17, 24, and 33 d posttransplant) and a single ileal biopsy (31 d posttransplant) were placed in culture with recombinant interleukin-2 (rIL-2) and phytohemagglutinin (PHA). T-cell phenotyping of cultured cells showed that CD8+ cells became dominant in all three tissues. The alloreactivity of biopsy-grown cells was determined using the primed lymphocyte test (PLT) and cell-mediated lympholysis test (CML). The proliferative and/or cytolytic responses of biopsy-grown cells to donor but not recipient or third party cells provided evidence for rejection and absence of GVHD. This donor-specific alloreactivity was detected before there was histologic evidence of rejection and during the period of active lymphoproliferation. This study suggests that the functional characterization of graft-infiltrating lymphocytes is useful in defining the immunologic events following multivisceral transplantation.
