Major cerebral hypoperfusion on an internal carotid loop during an otologic surgery: A case report.

An aberrant course of the internal carotid artery, such as a carotid loop or kinking, is a rare type of malformation. These malformations are typically asymptomatic, their occurrence is unpredictable, and they can exacerbate clinical disorders such as heart failure. We report the case of a seven-year-old child who died consecutively to cardiac arrest during otologic surgery for a cholesteatoma. After rapid and effective cardiorespiratory resuscitation, the child was transferred to a paediatric intensive care unit. In the following days, pronounced cerebral hypoperfusion led to the death of the child. The autopsy revealed a right carotid loop and a left carotid kink that presumably led to the cerebral hypoperfusion.

Is a CT-scan of the medial clavicle epiphysis a good exam to attest to the 18-year threshold in forensic age estimation?

Computed tomography (CT) scan of the medial clavicular epiphysis is one of the methods recommended by the Study Group on Forensic Age Diagnostics to estimate the age of living individuals. The aim of our study was to assess the relationship between the skeletal maturation of the sternal end of the clavicle and the chronological age in a sample of French individuals, using a nine-stage classification. We retrospectively reviewed 319 chest CT-scans of individuals aged 15-30 years old (252 males, 67 females). Among males and females, all individuals with a complete fusion, or an ongoing fusion of more than one third of the total surface of the metaphysis were at least 18 years old. Our results were consistent with data in the literature indicating that individuals with a complete fused clavicle were at least 18 years old. Similar studies with the same methods allow for creating a database of samples from different countries to confirm the validity of this method and its excellent results in forensic age estimation of living individuals.
