  Anatomy skills are considered essential in all aspects of medical practice, and more so now than before with increasing use of diagnostic imaging techniques and advanced surgery. In conjunction with the revision of the medical study curriculum at the University of Oslo in 2014, we investigated Norwegian physicians’ assessment of their own anatomy knowledge and the educational provision of anatomical skills during and after specialization. A total of 902 Norwegian physicians divided into the specialties of general medicine, internal medicine, surgery, neurology and radiology responded to an anonymous survey. As many as 73% of the physicians had at some time point experienced insufficient anatomy knowledge in their own practice, most commonly among surgeons and neurologists. The respondents expressed a need for supplementary educational provision in anatomy during and after specialization, and 36% were unfamiliar with such offers. Notably, dissection courses seemed unavailable during specialization. Our findings demonstrate a requirement for an improved supply of anatomy education during and after specialization. Anatomy courses that combine dissection, radiological images and clinical application would seem desirable.

  Aims/hypothesis Mortality due to cardiovascular disease (CVD), particularly coronary artery disease (CAD), is high in type 1 diabetic patients with end-stage renal disease (ESRD). We aimed to determine whether normoglycaemia, as achieved by successful simultaneous pancreas and kidney (SPK) transplantation, could improve long-term outcomes compared with living donor kidney-alone (LDK) transplantation. Methods We studied 486 type 1 diabetic patients with ESRD who underwent a first SPK ( n =256)orLDK( n =230)trans- plant between 1983 and 2012 and were followed to the end of 2014. Data were retrieved from the Norwegian Renal Registry and hospital records. Kaplan – Meier plots and multivariate Cox regression, with correction for recipient, donor and trans- plant factors, were used to examine potential associations between transplant type and all-cause and CVD- and CAD- related mortality. Results Median follow-up time was 7.9 years (interquartile range 4.3, 12.9). The adjusted HR for CVD-related deaths in SPK recipients compared with LDK recipients was 0.63 (95% CI 0.40, 0.99; p =0.047), while the HRs for all-cause and CAD-related mortality were 0.81 (95% CI 0.57, 1.16; p =0.25) and 0.63 (95% CI 0.36, 1.12; p =0.12),respectively. Compared with the LDK group, SPK recipients were younger and received grafts from younger donors. Cardiovascular mor- tality was higher in patients transplanted between 1983 and 1999 compared with those who received their grafts in subse- quent years. Conclusions/interpretation In patients with type 1 diabetes and ESRD, SPK transplantation was associated with reduced long-term cardiovascular mortality compared with LDK transplantation.

  Purpose Supposing divergent aetiology, we found it interesting to investigate outcomes between primary (PH) versus incisional (IH) hernias. In addition, we wanted to analyse the effect of defect closure and mesh fixation techniques. Methods 37 patients with PH and 70 with IH were enrolled in a prospective cohort-study, treated with laparoscopic ventral hernia repair (LVHR) and randomised to ± transfascial sutures. In addition, we analysed results from a retrospective study with 36 PH and 51 IH patients. Mean follow-up time was 38 months in the prospective study and 27 months in the retrospective study. Results 35 % of PH’s and 10 % of IH’s were recurrences after previous suture repair. No late infections or mesh removals occurred. Recurrence rates in the prospective study were 0 vs. 4.3 % (p = 0.55) and the complication rates were 16 vs. 27 % (p = 0.24) in favour of the PH cohort. The IH group had a mesh protrusion rate of 13 vs. 5 % in the PH group (p = 0.32), and significantly (p\0.01) larger hernias and adhesion score, longer operating time (100 vs. 79 min) and admission time (2.8 vs. 1.6 days). Closure of the hernia defect did not influence rate of seroma, pain at 2 months, protrusion or recurrence. An overall increased complication rate was seen after defect closure (OR 3.42; CI 1.25–9.33). Conclusions With PH, in comparison to IH treated with LVHR, no differences were observed regarding recurrence, protrusion or complication rates. Defect closure (raphe), when using absorbable suture, did not benefit long-term outcomes and caused a higher overall complication rate

Vis sammendrag

  Due to immunosuppressive (IS) therapy, incisional hernias are overrepresented in the organ-transplanted (Tx) population with larger defects, a high rate of recurrence, and a tendency toward more seromas and infectious problems. Thirty-one Tx/IS patients with a control group of 70 non-IS patients with incisional hernia (6/7 recurrences) were included in a prospective interventional study. Both cohorts were treated with laparoscopic ventral hernia repair (LVHR). Follow-up time and rate was 37 months and 95%. One hundred LVHR's were completed as there was one conversion in the Tx/IS group. No late infections or mesh removals occurred. Recurrence rates were 9.7% vs. 4.2% (P = 0.37) and the overall complication rates were 19% vs. 27% (P = 0.80). The Tx/IS group had a higher mesh-protrusion rate (29% vs. 13%, P = 0.09), but also larger hernias. Polycystic kidney disease was overrepresented in the Tx cohort (44% of kidney-Tx). Incisional hernias in Tx/IS patients may be treated by LVHR with the same low complication rate and recurrence rate as non-IS patients. By LVHR, the highly problematic seroma/infection problems encountered in Tx/IS patients treated by conventional open technique seem almost eliminated. The minimally invasive procedure seems particularly rational in the Tx/Is population and should be the method of choice. (ClinicalTrials.gov number: NCT00455299, date: 5 May 2006).
