Addressing the challenge of the emerging NCD epidemic: lessons learned from Botswana's response to the HIV epidemic.
2012
Authors: Reid MJ, Mosepele M, Tsima BM, Gross R
Botswana has the second highest prevalence of human immunodeficiency virus/acquired immune-deficiency syndrome (HIV/AIDS) in the world, and yet it has built one of Africa's most progressive and comprehensive HIV programs. While public health infrastructure has responded remarkably to the HIV epidemic, the prevalence of non-communicable diseases (NCDs), particularly diabetes mellitus and cardiovascular disease, in both HIV-infected and non-infected individuals, is increasing rapidly. Applying lessons learned from the scale-up of HIV/AIDS services may help with the implementation of an effective response to the challenges of the emerging NCD epidemic. We suggest that a successful response should include integrated service delivery, capacity building to provide disease-specific care, and strong partnerships to mobilize communities.
View on PubMedResidents' perspectives on the final year of medical school.
2012
Authors: O'Brien BC, Niehaus B, Teherani A, Young JQ
Objective
To characterize junior residents' perspectives on the purpose, value, and potential improvement of the final year of medical school.
Methods
Eighteen interviews were conducted with junior residents who graduated from nine different medical schools and who were in internal medicine, surgery, and psychiatry programs at one institution in the United States. Interview transcripts were coded and analyzed inductively for themes.
Results
Participants' descriptions of the purpose of their recently completed final year of medical school contained three primary themes: residency-related purposes, interest- or need-based purposes, and transitional purposes. Participants commented on the most valued aspects of the final year. Themes included opportunities to: prepare for residency; assume a higher level of responsibility in patient care; pursue experiences of interest that added breadth of knowledge, skills and perspective; develop and/or clarify career plans; and enjoy a period of respite. Suggestions for improvement included enhancing the learning value of clinical electives, augmenting specific curricular content, and making the final year more purposeful and better aligned with career goals.
Conclusions
The final year of medical school is a critical part of medical education for most learners, but careful attention is needed to ensure that the year is developmentally robust. Medical educators can facilitate this by creating structures to help students define personal and professional goals, identify opportunities to work toward these goals, and monitor progress so that the value of the final year is optimized and not exclusively focused on residency preparation.

2012
Authors: Virbalas JM, Bent JP, Parikh SR
Background. LCH is a benign vascular growth of the skin and mucous membranes commonly affecting the head and neck. Since it was first described in the nineteenth century, this entity has been variously known as "human botryomycosis" and "pyogenic granuloma." The shifting nomenclature reflects an evolving understanding of the underlying pathogenesis. We review the histopathology of and current epidemiological data pertaining to LCH which suggests that the development of these lesions may involve a hyperactive inflammatory response influenced by endocrine factors. We report two new cases of pediatric lobular capillary hemangioma (LCH) of the nasal cavity and review current theories regarding the etiology, diagnosis, and treatment of nasal LCH. Methods. Retrospective case series. Case Series. Two adolescent females presented with symptoms of recurrent epistaxis, nasal obstruction, and epiphora. Both patients underwent computed tomography imaging and biopsy of their intranasal mass. The tumors were excised using image-guided transnasal endoscopic technique. Seven other cases of nasal LCH have been reported to date in the pediatric population. Conclusion. Nasal LCH is a rare cause of an intranasal mass and is associated with unilateral epistaxis, nasal obstruction, and epiphora. We advocate for image-guided endoscopic excision of LCH in the adolescent population.

BACKGROUND
New supervisory regulations highlight the challenge of balancing housestaff supervision and autonomy. To better understand the impact of increased supervision on residency training, we investigated housestaff perceptions of education, autonomy, and clinical decision-making before and after implementation of an in-hospital, overnight attending physician (nocturnist).
METHODS
We established a nocturnist program in July 2010 at our academic, tertiary care medical center. We administered pre-surveys and post-surveys of internal medicine residents on night float rotation during the 2010-2011 academic year. We surveyed residents before and after experiencing the nocturnist program.
RESULTS
Housestaff reported an increase in the clinical value of the night float rotation (3.95 vs 4.27, P = 0.01) and the adequacy of overnight supervision (3.65 vs 4.30, P 0.0001) without a change in decision-making autonomy (4.35 vs 4.45, P = 0.44). Trainees agreed that nocturnist supervision positively impacted patient outcomes (3.79 vs 4.30, P = 0.002). Housestaff contacted attendings more frequently for transfers from outside facilities (2.00 vs 3.20, P = 0.006), during adverse events (2.51 vs 3.25, P = 0.04), prior to ordering invasive diagnostics (1.75 vs 2.76, P = 0.004), and prior to vasopressor use (1.52 vs 2.40, P = 0.004). Residents' fear of revealing knowledge gaps and desire to make decisions independently did not change.
CONCLUSIONS
Increased overnight supervision enhanced the clinical value of the night float rotation, increased rates of attending contact during critical clinical decision-making, and improved perception of patient care. These changes occurred without a decrease in housestaff's perceived decision-making autonomy.
View on PubMedPathogenetic and predictive value of biomarkers in patients with ALI and lower severity of illness: results from two clinical trials.
2012

Plasma and bronchoalveolar lavage (BAL) biomarkers related to the pathogenesis of acute lung injury (ALI) have previously been associated with poorer clinical outcomes and increased disease severity among patients with ALI. Whether these biomarkers have predictive value in a less severely ill population that excludes septic patients with high APACHE II scores is currently unknown. We tested the association of plasma and BAL biomarkers with physiological markers of ALI severity or clinically relevant outcomes in a secondary analysis of a clinical trial of activated protein C for the treatment of ALI. Plasma plasminogen activator inhibitor-1 (PAI-1) and mini-BAL protein were both significantly associated with increased oxygenation index (P = 0.02 and 0.01, respectively), whereas there was a trend toward an association between IL-6 and oxygenation index (P = 0.057). High plasma IL-6, thrombomodulin, and mini-BAL protein were all significantly associated with fewer ventilator-free days (VFDs) (P = 0.01, 0.01, and 0.05, respectively); no markers were associated with mortality, but we hypothesized that this was due to the small size of our cohort and the low death rate. To confirm these associations in a larger sample, we identified a restricted cohort of patients from the ARDS Network ALVEOLI study with similar baseline characteristics. We retested the associations of the significant biomarkers with markers of severity and clinical outcomes and studied IL-8 as an additional biomarker given its important predictive value in prior studies. In this restricted cohort, IL-6 was significantly associated with oxygenation index (P = 0.02). Both IL-6 and IL-8 were associated with decreased VFDs and increased 28-day mortality. Future studies should be focused on examining larger numbers of patients with less severe ALI to further test the relative predictive value of plasma and mini-BAL biomarkers for clinically relevant outcomes, including VFDs and mortality, and for their prospective utility in risk stratification for future clinical trials.

2012
Authors: Durr ML, Meyer AK, Huoh KC, Frieden IJ, Rosbe KW
OBJECTIVES/HYPOTHESIS
To describe the clinical presentation and airway characteristics of infants with airway hemangiomas and concomitant PHACE syndrome and to determine the prevalence of airway hemangiomas in PHACE subjects at our institution.
STUDY DESIGN
Case series.
METHODS
Retrospective review including clinical presentation, airway findings, treatment measures, and outcomes.
RESULTS
A total of 23 subjects were diagnosed with definite PHACE at our institution between September 1, 2005 and September 1, 2011. Twelve (52%) of these subjects had documented airway hemangiomas, six of whom were diagnosed and treated at our institution. All six subjects underwent direct laryngoscopy and bronchoscopy by a pediatric otolaryngologist. Five (83%) subjects had subglottic hemangioma. Three subjects (50%) had additional hemangioma within the airway located on the epiglottis, vocal folds, posterior pharyngeal wall, and tracheal wall. Five subjects (83%) were treated with propranolol, five (83%) were treated with systemic steroids, and one subject received vincristine. One subject required laser ablation of subglottic hemangioma and tracheotomy. All subjects were airway symptom free at last follow-up (average, 35 months; range, 13-76 months).
CONCLUSIONS
Airway hemangiomas can be a life-threatening complication of PHACE syndrome. At our institution, 52% of all PHACE subjects were diagnosed with airway hemangiomas. Early detection of airway involvement is paramount. Given the high rates of airway hemangiomas, we recommend performing direct laryngoscopy and bronchoscopy in all PHACE patients with respiratory symptoms. We recommend having a low threshold for airway evaluation in asymptomatic PHACE patients, especially those who will not be otherwise started on propranolol.
View on PubMedDo adult disease severity subclassifications predict use of cyclophosphamide in children with ANCA-associated vasculitis? An analysis of ARChiVe study treatment decisions.

OBJECTIVE
To determine whether adult disease severity subclassification systems for antineutrophil cytoplasmic antibody-associated vasculitis (AAV) are concordant with the decision to treat pediatric patients with cyclophosphamide (CYC).
METHODS
We applied the European Vasculitis Study (EUVAS) and Wegener's Granulomatosis Etanercept Trial (WGET) disease severity subclassification systems to pediatric patients with AAV in A Registry for Childhood Vasculitis (ARChiVe). Modifications were made to the EUVAS and WGET systems to enable their application to this cohort of children. Treatment was categorized into 2 groups, "cyclophosphamide" and "no cyclophosphamide." Pearson's chi-square and Kendall's rank correlation coefficient statistical analyses were used to determine the relationship between disease severity subgroup and treatment at the time of diagnosis.
RESULTS
In total, 125 children with AAV were studied. Severity subgroup was associated with treatment group in both the EUVAS (chi-square 45.14, p 0.001, Kendall's tau-b 0.601, p 0.001) and WGET (chi-square 59.33, p 0.001, Kendall's tau-b 0.689, p 0.001) systems; however, 7 children classified by both systems as having less severe disease received CYC, and 6 children classified as having severe disease by both systems did not receive CYC.
CONCLUSION
In this pediatric AAV cohort, the EUVAS and WGET adult severity subclassification systems had strong correlation with physician choice of treatment. However, a proportion of patients received treatment that was not concordant with their assigned severity subclass.

A comparison of two standard-setting approaches in high-stakes clinical performance assessment using generalizability theory.
2012
Authors: Richter Lagha RA, Boscardin CK, May W, Fung CC
PURPOSE
Scoring clinical assessments in a reliable and valid manner using criterion-referenced standards remains an important issue and directly affects decisions made regarding examinee proficiency. This generalizability study of students' clinical performance examination (CPX) scores examines the reliability of those scores and of their interpretation, particularly according to a newly introduced, "critical actions" criterion-referenced standard and scoring approach.
METHOD
The authors applied a generalizability framework to the performance scores of 477 third-year students attending three different medical schools in 2008. The norm-referenced standard included all station checklist items. The criterion-referenced standard included only those items deemed critical to patient care by a faculty panel. The authors calculated and compared variance components and generalizability coefficients for each standard across six common stations.
RESULTS
Norm-referenced scores had moderate generalizability (ρ = 0.51), whereas criterion-referenced scores showed low dependability (φ = 0.20). The estimated 63% of measurement error associated with the person-by-station interaction suggests case specificity. Increasing the number of stations on the CPX from 6 to 24, an impractical solution both for cost and time, would still yield only moderate dependability (φ = 0.50).
CONCLUSIONS
Though the performance assessment of complex skills, like clinical competence, seems intrinsically valid, careful consideration of the scoring standard and approach is needed to avoid misinterpretation of proficiency. Further study is needed to determine how best to improve the reliability of criterion-referenced scores, by implementing changes to the examination structure, the process of standard-setting, or both.
