The 'law of diminishing returns' is also seen after serial distraction using MCGR. Compared to previously published data for CGRS, there is a gradual linear decline rather than a rapid initial decline in lengthening. In older, heavier children a reduced distraction ratio in the concave rod of the MCGR device is noted over time. Cite this article: 2017;99-B:1658-64.
The progression of EOS can be controlled using MCGRs allowing growth and improved function. Younger and syndromic children are more likely to develop complications following surgery. Cite this article: Bone Joint J 2018;100-B:1187-1200.
Introduction: Cognitive impairment (CI) is very common condition that occurs in haemodialysis patients and it is associated with reduced functional capacity and mortality. We assessed the change in cognitive function during haemodialysis and associated risk factors. Methods: All patients ≥50 years, on haemodialysis for ≥3 months, no dementia from 2 dialysis centres were selected. Cognition was assessed before and after a haemodialysis session using parallel versions of the Montreal Cognitive Assessment (MOCA) tool. Multiple regression was used to examine potential confounders. Results: Eight-two patients completed both tests – median age 73 (52–91) years, 59% male, dialysis vintage 41 (3–88) months. Sixty-two (76%) had CI at baseline. Cognition declined over dialysis (MOCA 21 ± 4.8 to 19.1 ± 4.1, p < 0.001) and domains affected were attention, language, abstraction and delayed recall. Age and dialysis vintage were independently associated with decline. Conclusion: Cognitive function declines over a haemodialysis session and this has significant clinical implications over health literacy, self-management and tasks like driving. More research is needed to find the cause for this decline in cognition.
Magnetically controlled growth rods provide an alternative solution to traditional growing rods in the surgical management of children with early onset scoliosis, supporting growth of the spine while controlling curve progression. Their use has clear psychosocial and economic benefits, with the reduction of the need for repeat surgery as required with traditional growing rods. Cite this article: Bone Joint J 2018;100-B:507-15.
Recurrent abdominal pain is a common problem in children that may need invasive procedures for diagnosis. Hereditary angioedema (HAE) is rarely considered in the differential diagnosis. Here it is reported a girl with HAE, who presented initially as recurrent abdominal pain without cutaneous manifestations. Each episode was managed elsewhere as an acute surgical emergency and an exploratory laparotomy was planned. Diagnosis was confirmed by quantitative assay of C1 inhibitor. On detailed evaluation, many members of her family were affected.
The incidence of PJK in EOS patients treated with magnetic rods is favourably comparable to that reported with traditional growth rods. Also, children who are male, syndromic, hyperkyphotic, and younger must be monitored closely.
With the increasing median age of survival in the UK, there is an increased burden on the provision of medical and surgical care to the population. The
