Skin cancer was found in 31 of 598 patients transplanted in Oxford. No cases occurred during the first 3 years after transplantation but the prevalence rose after 12 years to 18.2 per cent. The main risk factors predisposing to skin cancer were the time after transplantation and male sex. Comparison with data from other centres suggests that exposure to ultraviolet light is a major aetiological factor in the speed of development of skin cancer. As the incidence of new cases rose progressively with time in our patients, it would seem that skin cancer is likely to become a major clinical problem as more patients enjoy prolonged survival after renal transplantation. Preventative and screening measures should be taken by transplant units both in the UK and in other countries with similar temperate climates.

Object The object of this study was to clarify whether improved developmental attainment following surgical correction of sagittal synostosis (SS), previously identified at initial postoperative assessment, is maintained at longer-term follow-up at 5 years of age. Methods The study involved 32 children with SS who underwent corrective surgery at a mean (± SD) age of 8.5 ± 7.25 months (range 2.8–39.9 months). All the children were assessed preoperatively, at 7 months postoperatively, and at 5 years of age, using the Griffiths Mental Development Scales. A control group consisted of 23 children with SS who had received developmental assessment on 2 or more occasions without surgical intervention (8 of these children had had follow-up at 5 years of age). Results The data indicated that, prior to surgical correction, children with SS had poorer Gross Locomotor function than other areas of development and that, following surgical intervention, the deficit resolved (even where there was severe developmental delay). The results further showed that improvement in Gross Locomotor function observed at 7 months postoperatively was further improved upon by 5 years of age. The same was true for their overall General Quotient, even in those children exhibiting severe developmental delay. Lesser improvements across time were shown for other skill areas. The children with SS who did not undergo surgery did not show any improvement in development, and in fact a deterioration in fine locomotor control was identified in these patients. Conclusions The results of this study suggest that corrective surgery for SS has a positive early impact on development, which is maintained and improved upon by 5 years of age, and that this surgery therefore offers more than simply a cosmetic improvement. Furthermore, the results suggest that not operating on children with SS means not only that this opportunity for developmental gain is missed, but that it may also cause an actual deterioration in developmental attainment.
