Fatal case of Rapunzel syndrome in neglected child

Rapunzel syndrome is very extreme form of trichobezoar formation where the tail of the trichobezoar extends from the stomach into the small intestine. Death resulting from this condition is rare and is usually associated with gastric or intestinal perforation. We report a fatal case of Rapunzel syndrome in a 3 years and 10 months old girl. Review of the literature indicates that this case involves the youngest child to have died from this syndrome. Furthermore, this case is unique due to the clear association with the parent's neglect with failure to provide the child with adequate health care.     

Age-related distribution of longitudinal pre-strain in abdominal aorta with emphasis on forensic application

It is a well-known fact that the length of an artery in situ and the length of an excised artery differs. Retraction of blood vessels is usually observed. This pre-tension plays crucial role in arterial biomechanics. It augments an artery wall load-bearing capacity. This paper presents the longitudinal pre-strain of the human aorta as an index of human age. The length of abdominal aortas was measured during autopsies before and after segment resection. The longitudinal pre-strain was calculated in 130 donors; 100 male and 30 female bodies. The pre-strain was defined as the ratio between in situ length and the length after the excision. The mean pre-strain was found to be 1.18±0.10 for male and 1.14±0.10 for female sample (mean±standard deviation). The age in the male group was 41.6±15.9 years; and 47.7±17.7 years in the female group. Statistical analysis revealed the correlation coefficient between age and pre-strain r=-0.821 and r=-0.839 in male and female group, respectively. The analysis also confirmed close correlation between aortic circumference and age; and between circumference and pre-strain. Linear and power law regression equations were employed and prediction intervals were computed. The power law estimates the age more accurately than linear one model. Nevertheless, especially for small values of the pre-strain (aged individuals) the linear model can be advantageous.
