Diagnostic errors during perceptual learning in dermatology: a prospective cohort study of Finnish undergraduate students.

Background: Perceptual learning modules (PLMs) have been shown to significantly improve learning outcomes in teaching dermatology.

Objectives: To investigate the quantity and quality of diagnostic errors made during undergraduate PLMs and their potential implications.

Methods: The study data were acquired from 8 successive dermatology courses (2021-23) from 142 undergraduate medical students.

Brain magnetic resonance imaging findings six months after critical COVID-19: A prospective cohort study.

Background: COVID-19 patients suffered from neurological symptoms in the acute phase. Whether this led to long-term consequences was unknown. We studied long-term brain MRI findings in ICU-treated COVID-19 patients and compared them with findings in groups with less severe acute disease.

Subjectively preferred octave size is resolved at the late stages of cerebral auditory processing.

Human listeners prefer octave intervals slightly above the exact 2:1 frequency ratio. To study the neural underpinnings of this subjective preference, called the octave enlargement phenomenon, we compared neural responses between exact, slightly enlarged, oversized, and compressed octaves (or their multiples). The first experiment (n = 20) focused on the N1 and P2 event-related potentials (ERPs) elicited in EEG 50-250 ms after the second tone onset during passive listening of one-octave intervals.

Perceptual learning in dermatology-A Finnish cohort study of undergraduate medical students.

Background: Implicit visual skills play an important role in the recognition of skin-related conditions.

Objectives: We aimed to evaluate effectiveness and practicability of digital perceptual learning modules (PLMs) during undergraduate teaching of dermatology.

Methods: The study consisted of four subsequent dermatology courses including 105 medical students.
