Student-perceived exam difficulty may trump the effects of different quality improvement measures regarding the students' evaluation of a pediatric lecture series.

Background: Lectures are still an important part of today's medical education at many medical schools. The pediatric lecture series at the Center for Pediatrics, Medical Center, University of Freiburg, Faculty of Medicine, University of Freiburg, Germany had been evaluated poorly in recent terms.

Methods: To improve lecture quality and possibly evaluation results a combination of measures consisting of peer lecturer coaching, use of an audience response system, in depth analysis of the end of term evaluation results and changes to the exam itself were implemented.

Everolimus-associated perianal ulcers in an eight-month-old heart transplant recipient.

mTOR inhibitors have a wide spectrum of therapeutic applications in adults and children. Little is known, however, about serious adverse effects in children undergoing mTOR inhibitor therapy. Oral ulcers are common and sometimes severe, but no other gastrointestinal involvement has been reported so far.

Adverse effects after the use of JWH-210 - a case series from the EU Spice II plus project.

Since 2009, more than 140 different synthetic cannabinoids (SC) have been identified in herbal mixtures consumed as recreational drugs. Knowledge of the acute toxicity of each individual compound remains sparse. Here we present a retrospective observational case series of patients presenting to emergency departments with analytically confirmed intake of JWH-210 as the only SC detected in serum samples.

Toward a consensus on reference values for thyroid volume in iodine-replete schoolchildren: results of a workshop on inter-observer and inter-equipment variation in sonographic measurement of thyroid volume.

Objective: Interpretation of thyroid ultrasonography for assessing goiter prevalence requires valid reference criteria from iodine-sufficient populations. Reports have suggested the current reference criteria for thyroid volume (T(vol)) of WHO/ICCIDD (International Council for the Control of Iodine Deficiency Disorders) may be too high. Our objective was to determine if inter-observer and/or inter-equipment variability contributes to the disagreement in sonographic T(vol) in children reported from iodine-sufficient areas.
