E-learning and practical performance in musculoskeletal ultrasound: a multicentre randomized study.

Objectives: To examine the effect of pre-course e-learning on residents' practical performance in musculoskeletal ultrasound (MSUS).

Methods: This was a multicentre, randomized controlled study following the Consolidated Standards of Reporting Trials (CONSORT) statement. Residents with no or little MSUS experience were randomized to either an e-learning group or a traditional group.

Training and assessment of musculoskeletal ultrasound and injection skills-a systematic review.

Methods: A systematic search of PubMed, Cochrane Library and Embase was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and studies published from 1 January 2000 to 31 May 2021 were included.

[Medicine-caused itch, wounds and bullous skin in three patients with pseudoporphyria].

Pseudoporphyria cutanea tarda is a well described bullous skin disorder which resembles porphyria cutanea tarda. However, the levels of porphyrins in plasma, urine and faeces are normal. We present three cases of patients with classical symptoms of pseudoporphyria.

[Clinical review of pseudoporphyria].

Pseudoporphyria is a photosensitive bullous disease, which resembles porphyria cutanea tarda. Normal porphyrin levels in urine, stool and blood define pseudoporphyria. Pseudoporphyria is associated with chronic renal failure, haemodialysis, a variety of drugs (e.
