A forensic pathological study of eighty-two cases of adrenal hemorrhage

OBJECTIVE: To analyze the relationship between adrenal hemorrhage and the cause of death, age and gender. METHODS: Eighty-two cases of adrenal hemorrhage were statistically analyzed. RESULTS: Adrenal hemorrhage occurred mostly in cases of sudden death, infection, trauma and asphyxia. Male had more chance than female to have adrenal hemorrhage. Adrenal hemorrhage caused by sudden death, trauma and poisoning was more frequently seen in young adults, whereas adrenal hemorrhage in children as well as in fetus and newborns was often caused by infection as well as sudden death and asphyxia respectively. Adrenal hemorrhage caused by sudden death and asphyxia was mainly located in medulla, while the infection usually induced hemorrhage in cortex. Adrenal hemorrhage caused by trauma showed an equal opportunity in either the cortex or medulla. CONCLUSION: Our data indicate that adrenal hemorrhage might provide some clues in searching for the cause of death.

Death due to attack from chow dog.

It is estimated that between one and four million persons per year are bitten by dogs in the United States. While most injuries associated with the bites are minor, serious sequelae, and even death, may occur. Most victims of fatal dog attacks are children < 1 year of age or elderly women. The most frequent cause of death is hemorrhage and shock from major vessel damage. A case is reported in which an elderly woman was attacked by her pet Chow dog. The victim received multiple superficial abrasions, contusions, and lacerations from the dog attack. A large perforation of the right external pudendal vein and three perforations of the left superficial femoral vein resulted in exsanguination and death. Fractures of the left 2nd through 4th ribs with underlying pulmonary contusion were also found.     

Fatal renal hemorrhage after extracorporeal shock wave lithotripsy

Renal hematoma is one of the most severe complications of extracorporeal shock wave lithotripsy (ESWL). ESWL is used in the noninvasive treatment of urinary calculosis. The shock waves can lead to capillary damage, renal parenchymal or subcapsular hemorrhage. We present a case with fatal complication and the result of the medico-legal evaluation. A 71-year-old woman was treated by ESWL, renal hematoma was detected during the clinical observation, and the patient died. The death occurred despite close clinical observation as a consequence of a rare complication of ESWL. The mechanism of death was hemorrhagic hypovolemic shock due to renal hemorrhage complications due to ESWL for treatment of renal calculi. This therapeutic complication is a known complication of appropriate treatment.     

Fetal death from abruptio placentae associated with incorrect use of a seatbelt

A female driver, 24 weeks pregnant, was wearing a three-point seatbelt in the manner usual for nonpregnant women, when her automobile collided head-on with another vehicle. A cardiotocographic examination after the accident revealed the fetus to be alive. Five days after the accident, however, a cardiotocographic examination showed fetal death. At that time, a transverse ecchymotic band on the lower abdominal wall that had not been observed at the first examination was noticed. Eight days after the accident, the mother delivered a macerated female fetus. At autopsy, the baby showed no abnormality, but there was a hematoma on the placental surface toward the uterus. These results suggest that the fetus died of abruptio placentae associated with incorrect placement of the lap belt.     

Penetrating cardiac injuries. A pathological analysis of 20 autopsy cases

A total of 20 autopsy cases involving deaths due to penetrating cardiac injuries were analyzed pathologically: the causes of death of the victims who died before cardiorrhaphy were exsanguination or hemorrhagic shock in nine cases, pericardial tamponade in three, and a combination of the two in another three. Three of the remaining five cases of early postoperative death resulted from hemorrhagic shock, one resulted from pulmonary air embolism, and one resulted from a combination of hemorrhagic shock and coronary platelet embolism. We should pay more attention to air embolism and platelet embolism as causes of death of victims who have had penetrating cardiac injuries, whose exsanguinating hemorrhage and/or pericardial tamponade may be controlled by emergency-room thoracotomy and cardiorrhaphy.     

Acute poisoning involving the pyrrolidinophenone-type designer drug 4'-methyl-alpha-pyrrolidinohexanophenone (MPHP)

A 36-year-old woman consulted the medical emergency unit of a private health center for abdominal pain and gastroenteritis of 5 days duration. Acute right pyelonephritis was diagnosed. Five hours after admission she became unconscious in a state of clinical shock. She was transferred to an intensive care unit but resuscitation attempts were unsuccessful and she died 3 h later. Three days after death, she was buried in the family vault. Five days after the burial, her husband lodged a complaint with the public prosecutor because he had not received a clear explanation from the physicians concerning the cause of his wife's death. After analysis of the medical records of the deceased by two forensic pathologists, a medicolegal autopsy was ordered by the public prosecutor. The corpse was exhumed and autopsy performed 9 days after death. Massive hemoperitoneum was diagnosed with a macroscopically ruptured subcapsular hematoma. Pathological study confirmed acute right pyelonephritis and demonstrated the precise cause of the hemorrhage: rupture of the hepatic artery at the hilar part, following infectious arteritis which was probably secondary to the acute pyelonephritis. To the best of our knowledge, this is the first published report of such a case.     

致胎儿死伤的刑法评价

国内关于胎儿性致死伤的讨论,往往忽略中外刑法在是否规定堕胎罪问题上的明显差异性;自愿堕胎可谓一种自伤行为不构成犯罪,计生部门依法强制堕胎因存在违法性阻却事由而不构成犯罪;凡是违背孕妇意愿伤害胎儿(未导致孕妇死亡),致胎儿在母体内死亡的,或者在母体内受到重大伤害但经过治疗而没有留下后遗症的,以及在母体内受到严重伤害留下后遗症以致出生后不久死亡或者形成严重残疾的,都是对母体健康生育机能的侵害,故意为之的构成故意伤害罪,过失为之的构成过失致人重伤罪。     

Fatal lung hemorrhage in complex pulmonary angiodysplasia in a case of mongolism

A case of sudden and unexpected death of a boy with Down-Syndrome is reported. Death was due to acute excessive haemorrhage from the lungs. There were no cardiac anomalies. Histology revealed in addition to mediahyperplasia, intimaproliferation and occlusions, multiple foci of anomalous ectatic blood vessels predominantly in the lungs, some of which ruptured and bled into adjacent airways. Evidence of previous less severe bleeding episodes was present. Further investigation showed a familial occurrence of the blood vessel anomaly.

Spontaneous umbilical cord hematoma: an unusual cause of fetal mortality: a report of 3 cases and review of the literature

Spontaneous hematoma of the umbilical cord represents a rare cause of fetal morbidity and mortality and the outcome is poor in half of the cases. There are many risk factors, such as infections, morphologic anomalies, alterations of the vessel walls, prolapses, twisting and traction of the cord, but in many cases the causes remain unknown. We present 3 cases of umbilical cord hematoma which took place at the end of the pregnancy and were followed by perinatal death of the fetus. In the 3 cases, which were autopsied including macroscopical and histopathologic examination of the placenta and the umbilical cord, a cordonal pathology was present; in all cases, there were alterations of the vascular wall, and in the third case inflammatory vasculopathy was found. In all 3 cases, the cause of death was attributed to acute anoxia due to the cordonal hematoma.     

Supine Hypotensive Syndrome as the Probable Cause of Both Maternal and Fetal Death

Abstract: Supine hypotensive syndrome is characterized by severe supine hypotension in late pregnancy, whose clinical presentation ranges from minimal cardiovascular alterations to severe shock, resulting from inferior vena cava compression by gravid uterus. We report a case of a 41‐year‐old 39‐week‐pregnant woman found dead supine. Autopsy revealed the following: cyanosis of the limbs; congestion of the jugular and subclavian veins; abundant abdominal subcutaneous fatty tissue; uterus displacing intestine and diaphragm; collapsed inferior vena cava; both femoral veins dilated and filled with blood; edematous and congested lungs; and placenta 790 g, fetus 3475 g, amniotic fluid 800 cm³. The diagnosis of supine hypotensive syndrome as the probable cause of death is supported by the position of the body and autopsy findings. This syndrome can be considered as the first stage of the physio‐pathological mechanism that led to death in the case presented herein and should be considered by pathologists as a cause of sudden death.     

Fatal rupture of hepatic adenomatosis: Autopsy case and review of the literature

Hepatic adenomatosis is a rare disease consisting of multiple adenomas in otherwise-normal liver parenchyma. Though the discovery of this entity goes back several years, its diagnosis is still challenging in terms of its definition and pathophysiology. Clinically, patients may be completely asymptomatic and the diagnosis is only made incidentally through imaging tests. The discovery could be made when complications occur such as intraperitoneal hemorrhage with hypovolemic shock due to the rupture of an adenoma. We report a fatal case of a ruptured adenoma in a case of hepatic adenomatosis discovered at autopsy. In order to achieve a better view of this disease, we conducted a literature review on this subject describing the pathogenesis, manifestations, and autopsy contribution to addressing this entity.     

Sudden death from massive pulmonary tumor embolism due to hepatocellular carcinoma

Massive pulmonary embolism in cancer patients can be due to detached thrombi or tumor. Pulmonary tumor embolism is often undiagnosed antemortem. We report a 52-year-old Chinese man admitted for management of hepatocellular carcinoma (HCC). Computerized tomography showed tumor involvement of hepatic vein and inferior vena cava. He died suddenly on the day of admission. At autopsy the main pulmonary arteries of both lungs were blocked by large tumor emboli, the immediate cause of death. Although rapid death in patients with HCC is usually caused by intraperitoneal hemorrhage from spontaneous rupture of tumor, massive pulmonary tumor embolism should also be considered in these patients, especially when antemortem evidence of hepatic vein and/or inferior vena cava invasion is present.     

Acute and subacute fetal CO-poisoning

The main principles of placental CO exchange in cases of CO intoxications of pregnant women are shown. Fetal COHb lags behind maternal COHb by several hours depending on the exposure pattern. During CO elimination the fetal COHb levels again lag behind the mother's. A case of a lethal CO intoxication of a pregnant woman, mens IX, with exposure time of 10-12 h and COHb of 75% for the mother and 46% for the fetus allows to make conclusions about process of intoxication and about different times of death for mother and fetus. In highly acute lethal intoxications of the mother COHb in fetal blood is low or negative. A vital danger of the fetus is not probable when mother survived a short CO exposure.     

Criminal burning

We report a study of 40 burnt bodies on which an autopsy was carried out at the Institut de Médecine Légale in Lyon (28 men/12 women, average age = 41 years, minimum age = 3 years, maximum age = 86 years). Criminal deaths (31%) represented the second cause of death after accidents (52%), and before suicide (16%). Criminal burning seemed mainly to be means of covering up homicide, whereas criminal immolation was rarer. The particular characteristics of each of these situations have been highlighted (tying or poisoning in criminal immolation). We deemed it essential to make X-rays, to look for injuries due to trauma and to carry out systematic toxicological analyses in a victim of burning.     

Rupture of an intracranial aneurysm--unusual complication of an electric shock.

Here we report about a 35-year-old electrical engineer who was found dead in his study. Postmortem examination revealed that death resulted because of subarachnoid and intraventricular hemorrhage caused by the rupture of an intracranial aneurysm. Right hand and left cheek revealed electrical marks with metallizations on skin, an electric shock was diagnosed to have preceded death. The close temporal correlation suggests that a sudden rise in blood pressure was caused by the electric current and was thus responsible for the rupture of the aneurysm.
