Hepatic encephalomyelopathy in a calf with congenital portosystemic shunt (CPSS)

A 4-month-old female Holstein Friesian calf was referred to the Veterinary Teaching Hospital, University of Berne, Switzerland for evaluation of ataxia, weakness, apathy and stunted growth. Clinical examination revealed generalized ataxia, propioceptive deficits, decreased menace response and sensibility. Postmortem examination did not reveal macroscopic changes of major organs. Histologically, the brain and the spinal cord lesions were characterized by polymicrocavitation, preferentially affecting the white matter fibers at the junction of grey and white matter and by the presence of Alzheimer type II cells. The liver revealed lesions consistent with a congenital portosystemic shunt, characterized by increased numbers of arteriolar profiles and hypoplasia to absence of portal veins. The pathological investigations along with the animal history and clinical signs indicated a hepatic encephalomyelopathy due to a congenital portosystemic shunt.

Pathological study on 18 cases of forensic re-autopsy and histopathological re-examination / 中国法医学杂志

Eighteen cases of forensic re autopsy and histopathological re examination were analyzed retrospectively. The manner and the impression of original autopsy,times of autopsy,the reason and manner of forensic re autopsy,the interval betwwen the original autopsy and the re autopsy as well as the last conclusions were analyzed.It was found that the forensic re autopsy always occured in cases of medical disputes(3 cases,16 7%) and death related to the police investigation(4 cases,22 2%).Only external examination and incomplete forensic autopsy were done originally in 13 out of 18 cases(72 2%).The conclusions of re autopsy were completely different from that of the original autopsy in 5 cases.Attension must be paid and prevention measures for re autopsy must be adopted were also discussed.
