Group 3 patients (n = 35) arrived with systolic BP>90. All patients in groups 1 and 2 expired. Injury Severity Scores for nonsurvivors …

The Competence-Related Abilities Of Adolescent Defendants In Criminal Court, Norman Poythress, Frances Lexcen, Thomas Grisso, Laurence Steinberg

Norman Poythress

Increasing numbers of youths are being tried in criminal court because of statutory measures that have decreased the use of judicial review as the primary mechanism for transfer. The relative immaturity of adolescents suggests that transferred youths might have impaired competence-related abilities compared to adults. To test this hypothesis, we compared the competence-related abilities and developmental characteristics of a sample of direct-filed 16-17-year-olds charged in criminal court in the state of Florida (Direct File sample) to a sample of 18-24-year-old adults charged in criminal courts (Adult Offender sample) and to a separate sample of 16-17-year-olds charged in juvenile court (Juvenile …

Emergence Of Candida Parapsilosis As The Predominant Species Causing Candidemia In Children., I Levy, L G Rubin, Sanjeev Vasishtha, V Tucci, S K Sood

Sanjeev Vasishtha MD

An increase in the rate of isolation of Candida parapsilosis, relative to other Candida species, in our children's hospital led us to analyze the clinical and epidemiological variables associated with candidemia. We sought to determine if these variables are different for patients infected with C. parapsilosis. All episodes of candidemia occurring over a 7-year period were analyzed retrospectively. Of 81 episodes in 80 patients, 35 (43%) were in neonates, and 46 (57%) were in nonneonates. C. parapsilosis was isolated in 40 episodes (49%). C. parapsilosis was significantly more likely than non-C. parapsilosis species to be associated with prematurity (P = …

Male Gender Is Associated With Increased Risk For Postinjury Pneumonia., Christopher J Gannon, Michael Pasquale, J Kathleen Tracy, Robert J Mccarter, Lena M Napolitano

Michael D Pasquale MD, FACS, FCCM

Nosocomial pneumonia in trauma patients is a significant source of resource utilization and mortality. We have previously described increased rates of pneumonia in male trauma patients in a single institution study. In that study, female trauma patients had a lower incidence of postinjury pneumonia but a higher relative risk for mortality when they did develop pneumonia. We sought to investigate the hypothesis that male trauma patients have an increased incidence of postinjury pneumonia in a separate population-based dataset. Prospective data were collected on 30,288 trauma patients (26,231 blunt injuries, 4057 penetrating injuries) admitted to all trauma centers (n = 26) …

Atomoxetine Treatment In Children And Adolescents With Attention-Deficit Hyperactivity Disorder: What Are The Long-Term Health-Related Quality-Of-Life Outcomes?, Amy Perwien, Christopher Kratochvil, Douglas Faries, Brigette Vaughan, Thomas Spencer, Ronald Brown

Ronald Brown

OBJECTIVE: Numerous investigations have examined the efficacy of pharmacological treatment for attention-deficit/hyperactivity disorder (ADHD) in children. However, relatively few studies have addressed the impact of treatment on long-term subjective, psychosocial outcomes, such as health-related quality of life (HRQL). This study examines the long-term effects of pharmacological treatment with atomoxetine on HRQL in children and adolescents with ADHD. METHODS: Participants included 6- to 17-year-old children and adolescents (n = 912) with ADHD enrolled in a 24-month, multicenter, open-label trial of atomoxetine. Outcomes included clinician ratings of ADHD, parent ratings of ADHD, and a widely used measure of HRQL (The Child Health …

Classification Of Dengue Illness Based On Readily Available Laboratory Data, James Potts, Stephen Thomas, Anon Srikiatkhachorn, Pra-On Supradish, Wenjun Li, Ananda Nisalak, Suchitra Nimmannitya, Timothy Endy, Daniel Libraty, Robert Gibbons, Sharone Green, Alan Rothman, Siripen Kalayanarooj

Sharone Green

The aim of this study was to examine retrospective dengue-illness classification using only clinical laboratory data, without relying on X-ray, ultrasound, or percent hemoconcentration. We analyzed data from a study of children who presented with acute febrile illness to two hospitals in Thailand. Multivariable logistic regression models were used to distinguish: (1) dengue hemorrhagic fever (DHF) versus dengue fever (DF), (2) DHF versus DF + other febrile illness (OFI), (3) dengue versus OFI, and (4) severe dengue versus non-severe dengue + OFI. Data from the second hospital served as a validation set. There were 1,227 patients in the analysis. The …

Mary M. Lee

BACKGROUND: In animal studies, organochlorine pesticide (OCP) exposure alters pubertal development; however, epidemiological data are limited and inconsistent. OBJECTIVE: To evaluate the associations of serum OCP concentrations [hexachlorobenzene (HCB), beta-hexachlorocyclohexane (beta-HCH), and p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE)] with male pubertal onset. METHODS: In Chapaevsk, Russia, a town environmentally contaminated with OCPs, 350 8-9 year old boys with measured OCPs were enrolled during 2003-2005 and were followed annually for eight years. We evaluated three measures of pubertal onset: testicular volume (TV) > 3 mL in either testis, or stage 2 or greater for genitalia (G2+), or pubic hair (P2+). We used multivariable interval-censored models to …

Association Between Chlorinated Pesticides In The Serum Of Prepubertal Russian Boys And Longitudinal Biomarkers Of Metabolic Function, Jane Burns, Paige Williams, Susan Korrick, Russ Hauser, Oleg Sergeyev, Boris Revich, Thuy Lam, Mary Lee

Mary M. Lee

Organochlorine pesticides (OCPs) have been linked to adult metabolic disorders; however, few studies have examined these associations in childhood. We prospectively evaluated the associations of baseline serum OCPs (hexachlorobenzene, beta-hexachlorocyclohexane, and p,p'-dichlorodiphenyldichloroethylene) in Russian boys with subsequent repeated measurements of serum glucose, insulin, lipids, leptin, and calculated homeostatic model assessment of insulin resistance (IR). During 2003-2005, we enrolled 499 boys aged 8-9 years in a prospective cohort; 318 had baseline serum OCPs and serum biomarkers measured at ages 10-13 years. Multivariable generalized estimating equation and mediation regression models were used to examine associations and direct and indirect (via body mass …

Sigrid A Blome-Eberwein MD

BACKGROUND: This randomized, open-label study evaluated Aquacel Ag Hydrofiber dressing with silver (HDS; ConvaTec, Skillman, NJ, USA) with an adherent or gelled protocol in the management of split-thickness donor sites. METHODS: HDS was the primary dressing in the adherent group (gauze as secondary covering) and gelled group (transparent film as secondary covering). Dressings were changed on study day 1 or 2 and study days 5 (optional), 10 (optional), and 14. The primary outcome was healing (>or=90% re-epithelialization) at study day 14. RESULTS: Seventy subjects were treated (36 adherent, 34 gelled). By study day 14, 77% of donor sites had …

Is It Abuse? Deaf Female Undergraduates' Labeling Of Partner Violence, Melissa Anderson, Caroline Kobek Pezzarossi

Melissa L. Anderson

The current study investigated the labeling of abuse experiences in a sample of 97 Deaf female undergraduate students, exploring the following questions: What is the prevalence of violent behaviors experienced by Deaf female undergraduates in their past-year relationships, what proportion of these relationships are identified as "abuse," and what scripts and strategies do Deaf female undergraduates utilize to label their experiences of partner violence? Results indicated that over half of the sample chose not to label past-year experiences of psychological aggression, physical assault, and sexual coercion as abuse, even when these experiences included severe violence. Implications for the Deaf education …

Intimate Partner Violence Against Deaf Female College Students, Melissa Anderson, Irene Leigh

Melissa L. Anderson

It has been estimated that roughly 25% of all Deaf women in the United States are victims of intimate partner violence (Abused Deaf Women's Advocacy Services [ADWAS]), a figure similar to annual prevalence rates of 16% to 30% for intimate partners in the general population. One goal of the present study was to ascertain the prevalence of intimate partner violence victimization in a sample of Deaf female college students. When comparing the prevalence of physical assault, psychological aggression, and sexual coercion victimization to hearing female undergraduates, the current sample was approximately two times as likely to have experienced victimization in …

Deaf Students And Their Classroom Communication: An Evaluation Of Higher Order Categorical Interactions Among School And Background Characteristics, Thomas Allen, Melissa Anderson

Melissa L. Anderson

This article investigated to what extent age, use of a cochlear implant, parental hearing status, and use of sign in the home determine language of instruction for profoundly deaf children. Categorical data from 8,325 profoundly deaf students from the 2008 Annual Survey of Deaf and Hard-of-Hearing Children and Youth were analyzed using chi-square automated interaction detector, a stepwise analytic procedure that allows the assessment of higher order interactions among categorical variables. Results indicated that all characteristics were significantly related to classroom communication modality. Although younger and older students demonstrated a different distribution of communication modality, for both younger and older …

Black Deaf Individuals' Reading Skills: Influence Of Asl, Culture, Family Characteristics, Reading Experience, And Education, Candace Myers, M. Diane Clark, Millicent Musyoka, Melissa Anderson, Gizelle Gilbert, Selina Agyen, Peter Hauser

Melissa L. Anderson

Previous research on the reading abilities of Deaf individuals from various cultural groups suggests that Black Deaf and Hispanic Deaf individuals lag behind their White Deaf peers. The present study compared the reading skills of Black Deaf and White Deaf individuals, investigating the influence of American Sign Language (ASL), culture, family characteristics, reading experience, and education. (The descriptor Black is used throughout the present article, as Black Deaf individuals prefer this term to African American. For purposes of parallel construction, the term White is used instead of European American.) It was found that Black Deaf study participants scored lower on …

From Case Management To Court Clinic: Examining Forensic System Involvement Of Persons With Severe Mental Illness, William Fisher, Ira Packer, Thomas Grisso, Melissa Mcdermeit, Julie-Marie Brown

Ira K Packer

The study examined the flow of a state mental health agency's case-managed clients into its forensic mental health court clinic systems for evaluation of competency to stand trial (CST) for a criminal offense. An analysis of merged encounter data from the case management and court clinic systems revealed that roughly 2% of the case-managed population were referred to court clinics for evaluation of CST during a 1-year period, but that these 2% represented roughly one eighth of that year's court clinic evaluees. The likelihood of this involvement was higher for males, African-Americans, and Latinos, and for persons with a history …

Evaluation Of Short And Tall Stature In Children, Benjamin Nwosu, Mary Lee

Mary M. Lee

Children and adolescents whose heights and growth velocities deviate from the normal percentiles on standard growth charts present a special challenge to physicians. Height that is less than the 3rd percentile or greater than the 97th percentile is deemed short or tall stature, respectively. A growth velocity outside the 25th to 75th percentile range may be considered abnormal. Serial height measurements over time documented on a growth chart are key in identifying abnormal growth. Short or tall stature is usually caused by variants of a normal growth pattern, although some patients may have serious underlying pathologies. A comprehensive history and …

T Cell Receptor Vbeta Gene Usage In Thai Children With Dengue Virus Infection, Susan Gagnon, Anita Leporati, Sharone Green, Siripen Kalayanarooj, David Vaughn, Henry Stephens, Saroj Suntayakorn, Ichiro Kurane, Francis Ennis, Alan Rothman

Alan Rothman

T lymphocyte activation during dengue is thought to contribute to the pathogenesis of dengue hemorrhagic fever (DHF). We examined the T cell receptor Vbeta gene usage by a reverse transcriptase-polymerase chain reaction assay during infection and after recovery in 13 children with DHF and 13 children with dengue fever (DF). There was no deletion of specific Vbeta gene families. We detected significant expansions in usage of single Vbeta families in six subjects with DHF and three subjects with DF over the course of infection, but these did not show an association with clinical diagnosis, viral serotype, or HLA alleles. Differences …

Family Presence During Trauma Resuscitation: Ready For Primetime?, Mae Pasquale, Michael Pasquale, Leslie Baga, Sherrine Eid, Jane Leske

Michael D Pasquale MD, FACS, FCCM

BACKGROUND: The concept of family presence during trauma resuscitation (FPTR) remains controversial. Healthcare providers have expressed concern that resuscitation of severely injured trauma patients is inappropriate for family members as they may have psychologic distress, disrupt resuscitative efforts, or misinterpret provider actions, which can ultimately impact satisfaction with care. The minimal evidence that exists is descriptive or anecdotal.

METHODS: Using a previously developed FPTR protocol, a prospective, comparative study assessing 50 adult family members, who were present (n = 25) or not present (n = 25) with their severely injured adult family member during resuscitation, was conducted. Family member anxiety …

Hips Can Lie: Impact Of Excluding Isolated Hip Fractures On External Benchmarking Of Trauma Center Performance, David Gomez, Barbara Haas, Mark Hemmila, Michael Pasquale, Sandra Goble, Melanie Neal, N Mann, Wayne Meredith, Henry Cryer, Shahid Shafi, Avery Nathens

Michael D Pasquale MD, FACS, FCCM

BACKGROUND: Trauma centers (TCs) vary in the inclusion of patients with isolated hip fractures (IHFs) in their registries. This inconsistent case ascertainment may have significant implications on the assessment of TC performance and external benchmarking efforts. METHODS: Data were derived from the National Trauma Data Bank (2007-8.1). We included patients (aged 16 years or older) with Injury Severity Score value ≥ 9 who were admitted to Level I and II TCs. To ensure data quality, we limited the study to TC that routinely reported comorbidities and Abbreviated Injury Scale codes. IHF were defined as patients, aged 65 years or older, …

Prevalence Of Sexual Abuse Among Women Seeking Gynecologic Care In Germany, Ursula Peschers, Janice Du Mont, Katharina Jundt, Mona Pfurtner, Elizabeth Dugan, Gunther Kindermann

Elizabeth Dugan

OBJECTIVE: To estimate the prevalence of sexual abuse among patients seen for gynecologic care in Germany. METHODS: A short anonymous questionnaire was distributed to 1157 women attending a gynecologic outpatient clinic at a large urban teaching hospital. Data collected using the questionnaire included patient characteristics, sexual abuse history, and screening practices. Women who reported that they had been abused were asked if they had ever discussed the issue with their gynecologist. RESULTS: A total of 1075 questionnaires were returned, for a response rate of 92.9%. Almost half (n = 479 [44.6%]) of the women surveyed reported that they had been …

Effects Of A Multicomponent Wellness Intervention On Dyslipidemia Among Overweight Adolescents, Olga Hardy, Jean Wiecha, Albert Kim, Carlos Salas, Rayna Briceno, Kwesi Moody, Joan Becker, Greer Glazer, Carol Ciccarelli, Ling Shi, Laura Hayman

Laura L. Hayman

Behavioral changes are the first line of treatment for dyslipidemia in adolescents, but outcome data on the effectiveness of this approach are inconsistent. This study aims to assess the effect of a 13-week multicomponent wellness intervention program, which included weekly nutrition classes and structured cardiovascular, flexibility, and strength training on dyslipidemia in nine overweight/obese [body mass index (BMI) > or = 85th percentile] and nine lean (BMIpercentile) adolescents. Clinical measurements and lipid profile assessment were performed before and after the intervention. At the completion of the study, the overweight/obese adolescents demonstrated a 15% increase in high-density lipoprotein cholesterol (HDL-C) levels (mean, …

Increased Toll-Like Receptor (Tlr) Mrna Expression In Monocytes Is A Feature Of Metabolic Syndrome In Adolescents, Olga Hardy, Albert Kim, Carol Ciccarelli, Laura Hayman, Jean Wiecha

Laura L. Hayman

BACKGROUND: Metabolic syndrome (MetSyn) is diagnosed frequently in some but not all overweight adolescents. Chronic inflammation, as seen in obesity, is strongly associated with MetSyn. OBJECTIVES: The aim of this pilot study was to assess the correlation between activation of the innate immune system and MetSyn, independent of body mass index (BMI), in a young population. METHODS: We quantitatively measured both systemic pro-inflammatory cytokines and gene expression of Toll-like receptors (TLRs) and downstream cytokines in circulating monocytes obtained from nine adolescents with metabolic syndrome (Overwt-MetSyn) and eight BMI-matched controls (Overwt-Healthy). RESULTS: The Overwt-MetSyn group demonstrated a significant elevation in expression …

Early Course Of Nicotine Dependence In Adolescent Smokers, Chyke Doubeni, George Reed, Joseph Difranza

Chyke A. Doubeni

OBJECTIVE: The goal was to characterize the early course of nicotine dependence. METHODS: Data were collected from 1246 sixth-graders in a 4-year (2002-2006) prospective study using 11 individual interviews. Subjects were monitored for 10 symptoms of dependence by using the Hooked on Nicotine Checklist. The bidirectional prospective relationship between the intensity of dependence (number of symptoms) and smoking frequency was examined by using cross-lagged analyses. RESULTS: Of the 370 subjects who had inhaled from a cigarette, 62% smoked at least once per month, 53% experienced dependence symptoms, and 40% experienced escalation to daily smoking. Smoking frequency predicted the number of …

Alcohol Exposure As A Risk Factor For Adverse Outcomes In Elective Surgery, Bharath Nath, Youfu Li, James Carroll, Gyongyi Szabo, Jennifer Tseng, Shimul Shah

Gyongyi Szabo

BACKGROUND AND AIMS: Alcohol consumption is a well-documented determinant of adverse perioperative outcome. We sought to determine the effect of active alcohol consumption following elective surgery. METHODS: We queried discharge records from the American College of Surgeons' National Surgical Quality Improvement Program (NSQIP, 2005-2007) for all elective adult admissions. The 7,631 (2.5%) patients with documented alcohol use (active alcohol use of at least two drinks per day within 2 weeks of surgery; ETOH use) underwent elective surgery; 301,994 (97.5%) patients denied ETOH use. Multivariate analysis was performed with adjustments for demographic and comorbid factors. Primary outcome measures included length of …

Ethanol-Mediated Regulation Of Transcription Factors In Immunocompetent Cells, Gyongyi Szabo, Pranoti Mandrekar

Gyongyi Szabo

The immunomodulatory effects of acute and chronic alcohol use are characterized by impaired antigen-specific immune activation and by increased susceptibility to infections due to alterations in innate immune responses and inflammatory mediator production. The central feature of cellular responses to inflammatory and stress signals is the activation of the nuclear regulatory kappa B/Rel family of transcriptional factors via various surface receptor systems in immunocompetent cells. Activation of NF-kappa B, however, is regulated at multiple levels including I-kappa B degradation, nuclear translocation, and by interaction of NF-kappa B/Rel with other transcription factors. Data from our and other laboratories demonstrate that acute …

Acute Ethanol Treatment Modulates Toll-Like Receptor-4 Association With Lipid Rafts, Angela Dolganiuc, Genadyi Bakis, Karen Kodys, Pranoti Mandrekar, Gyongyi Szabo

Gyongyi Szabo

BACKGROUND: Alcohol, a substance that is most frequently abused, suppresses innate immune responses to microbial pathogens. The host senses pathogens via Toll-like receptors (TLRs). Recent studies indicate that alcohol affects TLR signaling. METHODS: Here, we hypothesized that acute alcohol treatment may interfere with early steps of membrane-associated TLR2 and TLR4 signaling at the level of lipid rafts. Human monocytes and Chinese hamster ovary (CHO) cells, transfected with human TLR2, TLR4, or CD14, were stimulated with peptidoglycan (PGN, TLR2 ligand) or lipopolysaccharide (LPS, TLR4 ligand) with or without alcohol (50 mM) and analyzed for cytokine production (enzyme-linked immunosorbent assay), nuclear factor-kappaB …

Dual Task Performance In A Healthy Young Adult Population: Results From A Symmetric Manipulation Of Task Complexity And Articulation, Albert Armieri, Jeffrey Holmes, Sandi Spaulding, Mary Jenkins, Andrew Johnson

Andrew M. Johnson

The ability to execute and maintain gait while performing simultaneous cognitive, verbal, or motor tasks ('dual-tasking') is beneficial in many ways. It is well-documented, however, that dual-tasking can result in cognitive or motoric interference that results in diminished gait performance, and impaired secondary task performance. When manipulating cognitive load, it is common to have participants respond verbally to stimuli. While this is an ecologically valid way to measure the effects of cognitive load on gait, it ignores the additional demands inherent in the verbal aspect of the task. In the present study, we manipulated complexity and articulation within a single …
