Using Self-Regulated Learning Microanalysis to Examine Regulatory Processes in Clerkship Students Engaged in Practice Questions.

Introduction: Self-regulated learning is a cyclical process of forethought, performance, and self-reflection that has been used as an assessment tool in medical education. No prior studies have evaluated SRL processes for answering multiple-choice questions (MCQs) and most evaluated one or two iterations of a non-MCQ task. SRL assessment during MCQs may elucidate reasons why learners are successful or not on these questions that are encountered repeatedly during medical education. Methods: Internal medicine clerkship students at three institutions participated in a SRL microanalytic protocol that targeted strategic planning, metacognitive monitoring, causal attributions, and adaptive inferences across seven MCQs. Responses were transcribed and coded according to previously published methods for microanalytic protocols. Results: Forty-four students participated. In the forethought phase, students commonly endorsed prioritizing relevant features as their diagnostic strategy (n = 20, 45%) but few mentioned higher-order diagnostic reasoning processes such as integrating clinical information (n = 5, 11%) or comparing/contrasting diagnoses (n = 0, 0%). However, in the performance phase, students' metacognitive processes included high frequencies of integration (n = 38, 86%) and comparing/contrasting (n = 24, 55%). In the self-reflection phase, 93% (n = 41) of students faulted their management reasoning and 84% (n = 37) made negative references to their abilities. Less than 10% (n = 4) of students indicated that they would adapt their diagnostic reasoning process for these questions. Discussion: This study describes in detail student self-regulatory processes during MCQs. We found that students engaged in higher-order diagnostic reasoning processes but were not explicit about it and seldom reflected critically on these processes after selecting an incorrect answer. Self-reflections focused almost exclusively on management reasoning and negative references to abilities which may decrease self-efficacy. Encouraging students to identify and evaluate diagnostic reasoning processes and make attributions to controllable factors may improve performance.

Relapsed granulomatosis with polyangiitis with panhypopituitarism.

A man in his early 60s with a medical history of granulomatosis with polyangiitis (GPA) in remission for two decades without maintenance therapy presented with non-specific complaints of profound fatigue and 40-pound weight loss. He was seronegative for antinuclear antibodies and cytoplasmic antineutrophilic antibodies, but erythrocyte sedimentation rate and C reactive protein levels were elevated. Endocrinological testing revealed adrenal insufficiency, hypogonadism, hypothyroidism and diabetes insipidus. An MRI of the head revealed extensive sinonasal inflammation eroding through the floor of the sella turcica and into the pituitary gland and stalk. Biopsy of the sinonasal tissues was inconclusive. On review of his case, a multidisciplinary team diagnosed him with panhypopituitarism secondary to a recurrence of GPA. He responded well to glucocorticoids and methotrexate with marked reduction of pituitary enhancement on imaging and resolution of diabetes insipidus. He will require lifelong testosterone, levothyroxine and glucocorticoids for hormone replacement therapy.

Clinical and pathologic implications of extending the spectrum of maternal autoantibodies reactive with ribonucleoproteins associated with cutaneous and now cardiac neonatal lupus from SSA/Ro and SSB/La to U1RNP.

While the relationship between maternal connective tissue diseases and neonatal rashes was described in the 1960s and congenital heart block in the 1970s, the "culprit" antibody reactivity to the SSA/Ro-SSB/La ribonucleoprotein complex was not identified until the 1980s. However, studies have shown that approximately 10-15% of cases of congenital heart block are not exposed to anti-SSA/Ro-SSB/La. Whether those cases represent a different disease entity or whether another antibody is associated has yet to be determined. Moreover, the cutaneous manifestations of neonatal lupus have also been identified in infants exposed only to anti-U1RNP antibodies. In this review, we describe what we believe to be the first case of congenital heart block exposed to maternal anti-U1RNP antibodies absent anti-SSA/Ro-SSB/La. The clinical and pathologic characteristics of this fetus are compared to those typically seen associated with SSA/Ro and SSB/La. Current guidelines for fetal surveillance are reviewed and the potential impact conferred by this case is evaluated.

Psoriasis and psoriatic arthritis in African-American patients--the need to measure disease burden.

Gaps in knowledge exist regarding the clinical characteristics of psoriatic disease in ethnic minority patients. We evaluated validated clinical disease measures of psoriasis and psoriatic arthritis in African-American and Caucasian patients. Adult outpatients with confirmed diagnoses of psoriasis and psoriatic arthritis and seen at four urban academic institutions were eligible for evaluation. Validated patient and physician-reported disease outcome parameters, quality of life measures of psoriasis and psoriatic arthritis, and frequencies of systemic immunosuppressive therapies and patient comorbidities were documented. Psoriatic arthritis was less frequent in African-Americans compared to Caucasians (30 vs. 64.5 %, respectively, p < 0.001); however, African-Americans had more severe skin involvement [Psoriasis Area and Severity Index 8.4 (10.0) vs. Caucasians 5.5 (6.4), p = 0.06], with greater psychological impact and impaired quality of life. Use of biologic therapies was greater in Caucasian patients (46.2 vs. 13.3 % in African-Americans, p < 0.0001); yet, only one in four patients of the study cohort achieved minimal disease activity. Comorbidity was not associated with frequency of immunosuppressive drug use. In order to achieve a target of low disease activity and to reduce ethnic disparities in the care of psoriatic disease, the routine application of measures of disease status is needed.

Use of a medication control officer to reduce bias in a clinical trial: lessons learned from the scleroderma lung study.

BACKGROUND: Scleroderma Lung Study (SLS) was designed to evaluate the efficacy and safety of oral cyclophosphamide (CYC) versus placebo taken for 1 year for scleroderma-associated interstitial lung disease. An independent medication control officer (MCO), usually a physician, at each center was assigned to monitor laboratory and clinical toxicity of study medication and regulate its dosing based on these results. By having an MCO who watched and managed toxicity, the study investigators were free to care for study patients and to assess study outcomes without the potential bias of knowing toxicity data (toxicity from cyclophosphamide is distinctive - cytopenias and hematuria in particular). PURPOSE: To assess the usefulness of an MCO, whose chief role was to maintain safety while retaining the blinding in the clinical trial. METHODS: Patients had safety laboratory testing every 2-4 weeks and results were sent directly to the MCO within 2 days of the test. Other clinical adverse events (AEs) were reported by the patient to a nurse coordinator who reported them to the MCO who then managed the AEs to preserve the blinding of investigators caring for the patients. The MCO was provided pre-determined algorithms for dose adjustments of test medication based on the presence and severity of laboratory abnormalities. RESULTS: Safety monitoring by the MCO was effective in the early detection of drug toxicity with provision of appropriate medical intervention on a timely basis. At the same time, investigator blinding appeared to be maintained. LIMITATIONS: The testing of MCO effectiveness in maintaining blinding and consistency was not defined as an a priori hypothesis and thus complete data relating to the efficacy of the MCO were not collected in a prospective fashion. CONCLUSION: An MCO and pre-specified monitoring and dosing guidelines, coupled with uniform pre-specified responses to AEs, may be used effectively to preserve investigator blinding and provide consistency in response to AEs in a clinical trial setting, even when AEs of the test medication are distinctive.

Voriconazole-associated myositis.

Voriconazole is a new triazole antifungal agent that is now the treatment of choice for invasive aspergillosis. Drug-induced myopathy has never previously been reported with voriconazole, although it is recognized with other triazole agents. We present a 34-year-old female African American renal transplant recipient, with a prior history of probable statin-induced myopathy, who developed severe generalized weakness with marked elevation of muscle enzymes and inflammatory changes on T2-weighted fat-suppressed STIR sequence magnetic resonance imaging (MRI) after commencing voriconazole for treatment of invasive aspergillosis. Her symptoms resolved and creatine kinase normalized upon stopping the drug.Given the increased use of triazoles in immunosuppressed and transplant recipients, it is important for rheumatology consultants to include this entity in their differential diagnosis of weakness in such patients.

Teaching focused histories and physical exams in ambulatory care: a multi-institutional randomized trial.

PURPOSE: We needed specific strategies for students in diverse outpatient settings to more uniformly learn focused history and physical exam skills. METHODS: We conducted a randomized control trial to test the use of focused history and physical exam scripts in enhancing 3rd-year medical students' clinical skills at two medical schools. The article based scripts outlined focused outpatient encounters. The outcome measure was blinded analysis of progress notes using a standardized scale. Descriptive statistics were used to assess differences among student in each school, and study groups were compared using a t test. RESULTS: Five of 11 variables were statistically higher in the scripts group. These included history taking, physical examination, and overall score. CONCLUSION: Focus Scripts facilitated a specific task of learning to document focused evaluations in acute and chronic office visits.
