Aim Despite its declining incidence, sudden infant death syndrome ( SIDS) is still an important cause of death in infancy. This study investigated the environmental circumstances associated with SIDS, by analysing data from all sudden unexpected deaths in infancy ( SUDI) in Sweden from 2005 to 2011. Methods All Swedish infants forensically autopsied up to the age of 365 days from 2005 to 2011 were included. Medical records were obtained from the hospitals and supplementary data from the Swedish Medical Birth Register. Results Of the 261 infants, 136 were defined as SIDS and 125 as explained SUDI. The documentation in the medical records was poor when it came to issues such as bed sharing, sleep position, smoking, breastfeeding and pacifier use. The main findings were a significantly higher prevalence of bed sharing in SIDS than in explained deaths (odds ratio 7.77, 95% confidence interval 2.36-25.57) and that prone sleeping was still overrepresented. Bronchopneumonia, other infections and congenital anomalies were the most common causes of explained SUDI. Conclusion Bed sharing and prone sleeping were more common in SIDS than in explained SUDI. Sparse data in medical records were a problem, and the authors are now working with the National Board of Health and Welfare on a project to establish new routines. [ABSTRACT FROM AUTHOR]

Fat embolism is an incidental finding in cases of long bone fractures or other trauma, but it is also associated with liposuction and autologous fat transfer, a procedure where fat from liposuction is injected back into the same patient's face, breast, buttocks or penis. We here present a case of sudden death by fat embolism in a healthy young male, caused by a simple penis enlargement procedure, in which fat was injected into the penis shaft. We suggest that the risk of fat embolization might be higher when pretraumatized tissue is subjected to fat injection, like in this case, where a penis elongation was performed before the fat injection.
