Distributed practice has shown to be more effective for skills acquisition than massed training. However, it remains unknown as to which is the most effective distributed practice schedule for learning bronchoscopy skills through simulation training. This study compares two distributed practice schedules: One-day distributed practice and weekly distributed practice. Method Twenty physicians in training were randomly assigned to one-day distributed or weekly distributed bronchoscopy simulation practice. Performance was assessed with a pre-test, a post-test after each practice session, and a 4-week retention test using previously validated simulator measures. Data were analysed with repeated measures ANOVA. Results No interaction was found between group and test (F(4,72) <1.68, p>0.16), except for the measure 'percent-segments-entered', and no main effect of group was found for any of the measur...

In the period 2008-2010 there were three different types of employment for the assessment of competences in surgery. We found that doctors in training who had been employed in both orthopaedic and general surgery wards to a greater extent felt confident about their required competences in orthopaedic surgery. A majority of the 27 doctors participating in this survey felt that this kind of employment would be the best way to ensure the achievement of surgical competences.

The reform intends to ease students&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; transition from medical school to the foundation year, increase focus on communication, create more coherence between subjects, increase students&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; active participation, and align learning outcomes and assessments. More than 80 stakeholders participated in the first phases and five task forces gave their recommendations on how to achieve the intentions. The next phases are initiated on the basis of this solid work.

All patients had sustained at least one previous fracture of the distal forearm and had a bone mineral content of the contralateral forearm or bone mineral density of the lumbar spine lower than normal mean for age. Urinary phosphate/creatinine ratio increased in a dose-dependent fashion during treatment (P less than 0.001), whereas no significant changes were seen in serum phosphate or serum calcium. Serum parathyroid hormone (PTH) rose significantly (P less than 0.05) during treatment to a maximum of 36 and 33% in the groups receiving 1500 and 2250 mg/day, respectively, whereas serum 1,25-dihydroxycholecalciferol remained unchanged. In the group receiving 1500 mg/day, mean serum osteocalcin was increased in the period from day 1 to day 28 (P less than 0.05), but no significant changes were observed in urinary hydroxyproline/creatinine ratio, or serum bone alkaline phosphatase. We conclude that a short course of oral phosphate treatment increases serum PTH considerably. Furthermore, 1500 mg/day but not 2250 mg/day increases serum osteocalcin. No clear biochemical evidence, however, of increased activation of bone remodeling could be demonstrated in either group.

The degrees of reflux were equally distributed through the grades. 99mTc cystography was negative in 4 of 5 grade 2 refluxes and positive in 4 out of 5 grade 3-4 refluxes. Computerized dynamic tracings of the 123I renocystography showed an activity level increase over the kidneys of more than 1% of the bladder activity level in 47 units, 18 were equivocal and 21 negative. Grade 2 and 3 reflux found on the video VCU was refound on the renocystography. 24 false positives were found. It is concluded that 99mTc cystography performed as in our unit adds no further information to the diagnosis of reflux and that 123I renocystography diagnosing the more severe degrees of reflux may be a future method of non-invasive reflux control.

Iliac crest biopsies from 10 patients with otosclerosis and 20 normal controls were obtained after tetracycline double labelling and examined by histomorphometry. No significant differences were found in the estimates of density and remodeling of bone between patients and sex and age-matched normal controls. Qualitatively the bone specimens showed no signs of any generalized bone disorder.

It has been defined as specific information about the difference between a trainee&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s observed performance and a given standard with the intent of achieving performance improvement. Feedback is essential in medical education and has great implications for the educational climate. It has been shown that a common language regarding the principles of feedback has a sustained effect on quality and frequency of feedback. Further research is needed on feedback and educational climate, and on how to motivate trainees to improve future learning through feedback.

Previously, the course has been imparted as three course days with daytime training, but this time it had the form of one 24-hour session. The idea behind the new concept is to combine a high professional content with considerable change in the form of the course. The response from course participants was very positive, and the course organisers are most satisfied with the achieved results.
