Subdural hemorrhage: A unique case involving secondary vitamin K deficiency bleeding due to biliary atresia

Extrahepatic biliary atresia (EHBA) is a rare disease characterized by progressive and obliterative cholangiopathy in infants and is one of the major causes of secondary vitamin K deficiency bleeding (VKDB) due to cholestasis-induced fat malabsorption. Breast feeding increases the tendency of bleeding in EHBA patients because breast milk contains low amounts of vitamin K. A 2-month-old female infant unexpectedly died, with symptoms of vomiting and jaundice prior to death. She had been born by uncomplicated vaginal delivery and exhibited normal growth and development with breastfeeding. There was no history of trauma. She received vitamin K prophylaxis orally. In an emergency hospital, a CT scan showed a right intracranial hematoma and mass effect with midline shift to the left. In the postmortem examination, severe atresia was observed in the whole extrahepatic bile duct. Histologically, cholestasis, periductal fibrosis, and distorted bile ductules were noted. The gallbladder was not identified. A subdural hematoma and cerebellar tonsillar herniation were found; however, no traumatic injury in any part of the body was observed. Together, these findings suggest that the subdural hemorrhage was caused by secondary vitamin K deficiency resulting from a combination of cholestasis-induced fat malabsorption and breastfeeding. Subdural hemorrhage by secondary VKDB sometimes occurs even when vitamin K prophylaxis is continued. This case demonstrated that intrinsic factors, such as secondary VKDB (e.g., EHBA, neonatal hepatitis, chronic diarrhea), should also be considered in infant autopsy cases presenting with subdural hemorrhage.     

Dieulafoy lesion of the esophagus causing massive upper gastrointestinal bleeding and death: a case report

Dieulafoy lesion is a rare cause of upper gastrointestinal bleeding. We present a case report of sudden and unexpected death in a previously healthy male where autopsy revealed a classic Dieulafoy lesion with a submucosal artery protruding through a small mucosal defect in the esophagus, thereby exposing it to stress and consequent rupture. Advances in endoscopic techniques have drastically reduced mortality from Dieulafoy lesion. Nevertheless, it is an important diagnosis to be kept in mind when autopsy reveals an upper gastrointestinal bleeding.     

A case of sudden death due to spontaneous coronary artery dissection

Spontaneous dissection of the coronary arteries is an extremely rare event that occurs usually in middle-aged women and is mostly recognized at postmortem examination in victims of sudden death. It is a rare coronary pathologic finding whose precise incidence, etiology, pathogenesis, treatment, and evolution have not been clearly established. We present a sudden death case of a 53-year-old woman with spontaneous dissection of the left anterior descending coronary artery with eosinophilic coronary arteritis.

Sudden death due to cerebral leukemic hemorrhage occurring after acupuncture treatment for gingival bleeding

A 45-year-old woman who experienced stomalgia and gingival bleeding for several days died unexpectedly after acupuncture treatment. At autopsy, trivial injuries on the liver and the stomach and mild hemoperitoneum due to improper acupuncture were found. Also,acute lymphoblastic leukemia and hyperleukocytosis were diagnosed by postmortem examinations. Intracranial hemorrhage due to undiagnosed acute lymphoblastic leukemia was identified as the cause of death.Moreover, the relationship between therapeutic misadventure and death was also determined. We suggest that undiagnosed leukemia should be considered as a differential diagnosis when sudden death occurs owing to intracranial hemorrhage. If therapeutic misadventure was involved,it is also of great importance to assess the relationship between that and death in forensic expertise.     

Sudden, unexpected death due to massive, nontraumatic intra-abdominal hemorrhage in association with cirrhosis of the liver

Hemoperitoneum is usually due to rupture, laceration, or perforation of a blood vessel or organ. The author describes three deaths due to massive intra-abdominal hemorrhage, all in alcoholics with cirrhosis of the liver, in which no source for the bleeding was found. One of the three individuals, who was briefly hospitalized, showed evidence of a disseminated intravascular coagulopathy (DIC). In the author's opinion, this is the most likely cause of the intra-abdominal hemorrhage in the two other cases and is related to the cirrhosis of the liver.

Sudden death after a cold drink: case report

We report a case of sudden cardiac death in a 12-year-old boy after rapid ingestion of a frozen slurry drink. The cause of death was determined to be a cardiac arrhythmia secondary to a previously undiagnosed cardiac rhabdomyoma with associated myocardial scarring. Ingestion of cold liquids has been associated with syncope, but not sudden cardiac death. In this case, bradycardia induced by cold-induced vasovagal reflex may have precipitated the terminal arrhythmia. Ingestion of cold liquids should be considered a potential trigger for fatal cardiac arrhythmias in patients with underlying heart disease.     

Virtual anthropology and forensic identification: report of one case

A charred body was found after a fire in a house in a mountainous region of France. The body was severely burned and was not formally identified as the owner of the house. Autopsy was carried out to seek vital reactions and/or traumatic lesions and to identify the corpse. Before bone preparation and after autopsy, multislice computed tomography (MSCT) was performed in order to assess the potential of the technique for radiological anthropological bone identification. The challenge was to determine as accurately as possible the sex, age, ante-mortem stature and ethnic of the victim using both MSCT and conventional bone study. The results of the two techniques were compared. MSCT provided an answer to all the questions, whereas bone study did not. To the best of our knowledge, this case is the first to use MSCT for forensic anthropological study and illustrates the potential contribution of this technique in this field.     

A death due to ethchlorvynol abuse. A case report

A fatal case of ethchlorvynol abuse is reported with blood and tissue determinations.     

A case of suicide disguised as natural death.

A case report describing the suicide of a physician classified initially as a natural death. Faced with the vehement protest of the family of the deceased the magistrate decided to request a 'preventive' forensic autopsy. Forensic investigations revealed the cause of death as being a pentobarbital intoxication and the circumstances favoured the hypothesis of a genuine suicide. This case illustrates that the tendency of magistrates to request or not an autopsy is related to their experience or intuition.     

Simultaneous sudden infant death syndrome: a case report.

The first reported case of simultaneous sudden infant death syndrome (SSIDS) in Allegheny County, Pennsylvania, occurred on February 27, 1998. Two-month-old black fraternal twin girls were both found dead in their crib at the same time. After an in-depth death scene investigation, police investigation, toxicologic analysis, and complete autopsies, a specific cause of death could not be identified. The deaths of the two girls were therefore ruled simultaneous sudden infant death syndrome.     

Fatal postpartum spontaneous liver rupture: case report and literature review

Maternal hepatic rupture is a rare complication of pregnancy that can be fatal to both mother and child. This phenomenon is most often associated with preeclampsia/eclampsia and/or HELLP syndrome, which is defined by a collection of clinical features including hemolysis (H), elevated liver enzymes (EL), and a low platelet count (LP). These disease processes are typically identified and treated during pregnancy, often in the last trimester. The described case is unusual in that the decedent had no known history of preeclampsia/eclampsia or HELLP syndrome during this pregnancy, and she died suddenly several days postpartum of liver rupture with massive intraperitoneal hemorrhage following a routine cesarean section delivery and an uneventful hospital course. Similar cases are infrequent in the literature, which is reviewed in this report.     

Unusual sudden death: two case reports of hemorrhage by rupture of varicose veins

Although varicose veins are frequent, they are rarely considered lethal. Still, rupture of a varicosity can result in significant and even fatal hemorrhage. External hemorrhage is an unusual complication of this common venous pathology. Reported here are 2 cases of severe external hemorrhage resulting from the perforation of a varicose vein.

Virtual autopsy and forensic identification-practical application: a report of one case

The body of an unidentified elderly woman was found trapped in a floodgate. Prior to autopsy, full-body multislice computed tomography (MSCT) was performed for study of bone lesions and cause of death. Age was estimated by analysis of the sternal end of the fourth rib and of the pubic symphyseal medial articular surfaces. The results were then compared with the autopsy findings. MSCT was superior to autopsy in diagnosis of traumatic bone lesions and also revealed dental anomalies and signs of drowning. Age estimation gave a similar result for both methods. This case report illustrates the potential value of MSCT for medico-legal investigations of death: diagnosis of injuries, possibility of determining the cause of death, and anthropological study in order to estimate age or to visualize features likely to enable identification of a corpse.     

Unexpected childhood death due to a rare complication of ventriculoperitoneal shunting

A 10-year-old boy with Arnold-Chiari malformation, spina bifida, and a ventriculoperitoneal shunt for hydrocephalus died unexpectedly, having appeared to be only mildly unwell with fever on the night before death. At autopsy, the shunt was partially obstructed with an associated enterococcal meningitis. The tip of the shunt was located within the transverse colon, which was embedded in a mass of fibrous adhesions resulting from previous abdominal surgery. Blood cultures were sterile. Intestinal perforation is a rare complication of ventriculoperitoneal shunting that may be associated with the development of meningitis and unexpected death. The autopsy assessment of children with such indwelling devices requires examination of the functional state of the shunt, full septic workup, and determination of the precise location of the tip of the catheter within the peritoneal cavity.
