The shaken baby syndrome: a serious diagnosis on an insecure foundation?

The discussion concerning the causes of infantile subdural bleedings (SDB) as well as retinal hemorrhages has become quite controversial in the last few years. The long-standing interpretation that most of these cases are the result of abuse--especially by the shaken baby syndrome (SBS)--was doubted, and the role of accidental events was emphasized. In many cases, there are no objective witnesses who observed the incident and no unambiguous traces of abuse, so that the diagnosis "shaken baby syndrome" often has to be established indirectly. A subdural bleeding (SDB) in an infant can undoubtedly be due both to an accidental and an intentional injury. Therefore, the SDB itself does not allow to draw far-reaching conclusions as to its cause. However, if an infant died or was hospitalized in a deep coma with several bridging vein ruptures and minor subdural bleeding, these findings are not compatible with an alleged minor fall. In the presence of several bridging vein ruptures, most authors are of the opinion that this is the result of a significant traumatization. In contrast to most other reports, the reliable demonstration of BV ruptures is a routine element of the postmortem diagnostic procedures at the Berlin institute of forensic medicine. In this way, a mechanical trauma can be clearly identified as the cause of the infant's death. If several bridging veins are torn, this proves a significant trauma and rules out a banal incident. The current controversial discussion on the reliability of the SBS diagnosis often makes it difficult not only for the clinician, but also for the forensic expert, to draw safe conclusions in the presence of a combination of findings long considered typical of the shaken baby syndrome. This situation is the background for presenting and discussing the major SBS findings reported in the literature and comparing them with our own expiriences. In our opinion there is still no justification for a fundamental change in the position to interpret such cases as a consequence of severe trauma caused by another person.     

Extra- and intracranial injuries of the cerebral arteries as a sequela of assault

The case of an 47-year-old man is reported, who was injured in a fight while under the influence of alcohol. The culprit knocked him down and stamped several times on the left side of his head. The victim became unconscious. At the hospital, subarachnoid hemorrhage and massive ventricular bleeding was diagnosed via CT. Despite the implantation of a ventricular shunt, there was repeated massive cerebral pressure and arterial bleeding. Brain death occurred after 8 days. The main finding at autopsy was nearly complete disruption of the left inferior posterior cerebellar artery as the source of the lethal bleeding. The histological examination showed some additional, incomplete ruptures of this vessel and of the left intracranial vertebral artery. This is a typical result of "minor head injuries" sustained in fights: arterial rupture (ipsilateral) as a result of overstretching. Fracture of the left zygomatic arch and maxilla; no skull fracture; no primary traumatic brain damage. The extracranial carotid arteries were intact. When the vertebral arteries were examined (in the undamaged cervical spine), there was a surprising finding: distant dissection of the right vertebral artery between C1 and C2, which perhaps occurred as a result of compression (contralateral to the impact) of this region.     

Hypothermia Secondary to Glioblastoma Multiforme? Autopsy Findings in Two Cases

Death due to accidental primary hypothermia in cold climates is relatively common, with previous case series reflecting this. In contrast, hypothermia‐related death as a result of an underlying medical cause, such as a brain tumor, is rare. The literature clearly illustrates a theoretical causal relationship between brain neoplasms and hypothermia through the infiltration of the hypothalamus; however, the number of reported cases is minimal. Two cases are presented where autopsy confirmed hypothermia as the cause of death with both cases revealing widespread glioblastoma multiforme in the brain. Both decedents were elderly with a number of comorbidities identified during autopsy that could explain death; however, hypothermia was deemed the most likely cause. It is proposed that both decedents died of hypothermia as a result of the tumor's effect on thermoregulation. These cases underline the importance of forensic pathologists to be aware of the relationship between brain tumors and hypothermia and to not dismiss death as being due to other disease processes.     

Unexpected double lethal oleander poisoning

Nerium oleander is a very popular urban ornamental plant in Europe, but it is also extremely dangerous because it contains several types of glycosides, accidental ingestion of which can cause cardiac arrhythmias and even deaths. The rarity of such cases makes it difficult to think of oleander poisoning without evidences that suggest this possibility as the cause of the unexpected death. This report concerns the discovery of the bodies of 2 young people, a man and a woman, in a forest in conditions of extreme malnutrition. Medicolegal investigations showed neither pathologic nor traumatic causes of death, but the presence of vegetal remains in the stomach was noticed. A common toxicological analysis resulted negative, but the implementation of more detailed investigations showed the presence of digoxin in the blood of both cadavers, excluding the possibility of a pharmaceutical provenience of digoxin, this laboratory result was interpreted as evidence of ingestion of oleander, which contains oleandrine, the cross reaction of which with digoxin is widely described in the literature. Identification of the 2 subjects, which occurred after 4 years, strengthened the hypothesis of accidental poisoning by oleander because it was ascertained that the 2 young people were vegans--extreme vegetarians who reject the ingestion of foods of animal origin and live by eating only what they find in nature.     

Drowning of a Friedreich's ataxia patient

We here report an unusual, apparently accidental death, in which weakness associated with a progressive neuromuscular disease, Friedreich's ataxia, apparently resulted in the drowning of the deceased. The possibility of neuromuscular disease as a rare cause of drownings should not be overlooked.     

Cause and manner of death among users of anabolic androgenic steroids

Medicolegally investigated deaths among 34 male users of anabolic androgenic steroids (AAS) are described. Nine persons were victims of homicide, 11 had committed suicide, 12 deaths were judged as accidental and 2 as indeterminate. In two cases of accidental poisoning, the levels of pharmaceuticals and illicit drugs were considered too low to be the sole cause of death and AAS was considered part of the lethal polypharmacia. Chronic cardiac changes were observed in 12 cases. In two cases of accidental poisonous deaths, these changes were regarded as contributory cause of death. Homicides, suicides, and poisonings determined accidental or indeterminate in manner were related to impulsive, disinhibited behavior characterized by violent rages, mood swings, and/or uncontrolled drug intake. The observations in the present study indicate an increased risk of violent death from impulsive, aggressive behavior, or depressive symptoms associated with use of AAS. There are also data to support earlier reports of possible lethal cardiovascular complications from use of AAS. Furthermore, a contributing role of AAS in lethal polypharmacia is suggested. Finally, the observations indicate that use of AAS may be the gateway of approach to abuse of other psychotropic drugs.     

Death of an 89-year-old man during autosexual activity

Autoerotic fatalities are accidental deaths occurring as a direct result of autosexual activities, mostly involving men in the 2nd to 8th decade of life. Death most often occurs in the domestic environment due to strangulation or asphyxia. However, fatalities related to autosexual activity in a wider sense may also be caused by an accident or sudden death from an internal cause. We report the case of an aged man who died while engaged in outdoor autosexual activities due to a combination of a pre-existing internal disease and an accident (drowning).     

Intracranial sewing needle in a man with seizure: a case of child abuse?

Physical abuse in infancy can cause persistent neurological deficits. Although intracranial foreign bodies are generally secondary to penetrating trauma or surgical procedures, rarely they also occur as a result of child abuse. A 32-year-old man presented with the complaint of generalized tonic clonic seizures to the Neurology Department of Marmara, University Hospital. Computerized tomography (CT) scan revealed a sewing needle located within the temporal lobe. The location and the position of the needle suggested that it must have been introduced in infancy through the lamdoid suture before the closure of it, as an unsuccessful deliberate homicide attempt or accidental injury.     

Drug-related deaths with evidence of intracorporeal drug concealment at autopsy: five case reports

Intracorporeal concealment of illicit drugs is a rare observation at coronial autopsy examinations. The article reports 5 cases of accidental drug overdoses at the Westmead Coronial Morgue, Sydney New South Wales, over a 6-year period with evidence of intracorporeal drug concealment known as body packing or body stuffing. Three different forms of anatomic concealment of drugs are illustrated, Case 2 involving therapeutic medication in the form of glass ampoules for parenteral injection not previously reported. Three deaths were the result of acute toxicity due to polydrug abuse rather than as a consequence of the body packing behavior and rupture of the drug packaging, with the intracorporeal drug concealments an adjunct finding at the autopsy examinations. The cause of death in Case 3 was the direct result of acute cocaine intoxication due to rupture of drug packages in the rectum and mucosal absorption. The article details forensic sociological aspects of drug concealment and subcultural group human behavior that can assist in providing information for the initiation of investigations.     

A fatal case of hypothermia associated with hemorrhages of the pectoralis minor, intercostal, and iliopsoas muscles

In a morning in January, a male in his early sixties was found dead in an outdoor parking area. The minimum temperature during the night before he was found dead was estimated to be 4.0 degrees C. Autopsy revealed the pinkness of hypostasis, slight abrasions and bruises on the face and the extremities, collapse of the lungs, and slight gastric submucosal hemorrhage. Histologic examination revealed compact arrangement of cardiac muscle fibers and cytoplasmic vacuolation in the adenohypophysis. Toxicologic examination demonstrated hyperacetonemia (51.2 microg/mL). Ubiquitin, one of the stress proteins that are induced by several stimuli, including severe cold, was detected in several organs. We concluded that the cause of his death was lethal hypothermia. In addition, hemorrhages were observed in the subfascial and/or intramuscular parts of the pectoralis minor, first intercostal, and iliopsoas muscles. Although it has been reported that iliopsoas muscle hemorrhage can result from hypothermia, there have been few reports concerning hypothermia-associated hemorrhages of the pectoralis minor and/or intercostal muscles. We presumed that intense shivering and/or effort ventilation during the course of lethal hypothermia might cause these muscle hemorrhages.     

Subarachnoid Hemorrhage and Carbon Monoxide Exposure: Accidental Association or Fatal Link?

This case study reports a fatal subarachnoid hemorrhage (SAH) with concomitant accidental carbon monoxide (CO) exposure in 32‐year‐old man. Autopsy results indicated an antemortem aspiration of smoke, and a massive SAH was identified as the cause of death. Intriguingly, the carboxyhemoglobin level was 30%, suggesting that CO could have played a specific role. Intracranial hemorrhages following CO exposure in brain areas and tissues such as the basal ganglia, globus pallidus, or white matter are rare, but well characterized, whereas SAH related to CO exposure has not been previously described. In this case report, the possible role of CO, either as a primary cause or as a facilitating factor, in the pathogenesis of SAH is discussed. In particular, we propose the hypothesis that the excessive vasodilating effects produced by CO on the cerebral endothelium results in consequential loss of microvascular integrity.     

Quality assessment of perinatal and infant postmortem examinations in Turkey

An autopsy examination is important in identifying the cause of death and as a means of auditing clinical and forensic practice; however, especially in perinatal and infantile age groups determining the cause of death leads to some difficulties in autopsy practice. In this study, 15,640 autopsies recorded during the years 2000-2004 in the Mortuary Department of the Council of Forensic Medicine were reviewed. Autopsy findings of 510 cases between 20 completed weeks of gestation and 1 year of age were analyzed retrospectively. The quality of each necropsy report was assessed using a modification of the system gestational age assessment described by Rushton, which objectively scores aspects identified by the Royal College of Pathologists as being part of a necropsy. According to their ages, the cases were subdivided into three groups. Intrauterine deaths were 31% (158 cases), neonatal deaths were 24% (123 cases), and infantile deaths were 45% (229 cases) of all cases. Scores for the quality of the necropsy report were above the minimum acceptable score with 44% in intrauterine, 88% in neonatal and infantile deaths.     

Pathogenesis of conjunctival petechiae

Conjunctival petechiae from 15 cases (cause of death: different natural and unnatural) were analysed using confocal laser scanning microscopy (CLSM) in order to visualize the kind of the damage within the vessel wall (diapedesis versus rhexis). The pathomorphological findings with multiple ruptures of vessels appearing to be filled to bursting point define the conjunctival petechiae as a rhexis-haemorrhage.     

论西方福利法治国的成因

福利法治国在西方的产生与发展,既有深刻的历史根源、社会背景和经济动因,又是各种社会思潮、政治经济学说的兴起与争鸣所致;既有战争及偶然性因素的推动,又是市场经济发展到一定阶段的必然结果;既受国际关系和世界格局变化的影响,又经各国具体情况、文化传统等个性因素的塑造。其中,不容忽视的是,市场失灵是福利国产生的社会背景,建构论理性主义是福利国产生的知识困境,而民主的悖论则是其发生的制度原因。上述综合因素长期发酵、整合的结果导致了现代福利国家如牛负重、危机四伏。     

An autopsy case of heart rupture from a scooter accident with 3 riders

A 15-year-old male died of cardiac rupture due to blunt chest trauma from a traffic accident involving a low-speed scooter carrying 3 people and a head-on collision with a tree. The victim was sitting on the footrest of the scooter. It was concluded that the victim was compressed between the handlebar of the scooter and the other 2 passengers, causing cardiac ruptures via bidirectional compression and intravascular hydrostatic pressure. The victim may have served as a cushion for the other 2 passengers, who were not thrown from the scooter and sustained only minor injuries.     

Sudden death due to asphyxia by esophageal polyp: two case reports and review of asphyxial deaths

Asphyxia, not an uncommon cause of sudden death, may result from numerous etiologies. Foreign-body aspiration and strangulation are 2 extrinsic causes. Airway obstruction may also be caused by laryngeal edema, asthma, infection, or anaphylaxis. Chronic causes of asphyxia include musculoskeletal diseases (eg, muscular dystrophy, amyotrophic lateral sclerosis), neurologic disorders (eg, myasthenia gravis, multiple sclerosis), respiratory disease (eg, emphysema, chronic bronchitis), or tumors. The manner of death in cases of asphyxiation may be natural, accidental, homicide, or suicide. For the death investigator, determining the cause and manner of death can often be quite challenging.We report here 2 cases of an esophageal fibrovascular polyp causing sudden asphyxial death, review of the literature, and discussion of other differential diagnoses in the case of asphyxial death.     

An initially unexplained death during prison sentence. Diagnostic verification by atomic absorption spectrometry

The authors report on the death of a 25-year-old man due to electric current in prison, which was not recognized at first. The fatal accident was caused by a self-made electric kettle. The only electrothermal skin lesions were some pinhead-sized electric marks on the left thumb. Careful external inspection of the body in combination with an analysis of the conductor material (aluminium) by means of atomic absorption spectrometry (AAS) revealed the cause of death and the source of accidental electrocution.     

Hypothermia: a natural cause of death

Deaths due to hypothermia are usually accidental and are the result of exposure to extreme environmental temperatures. Often these individuals are intoxicated, elderly, or exposed to severe cold temperatures. We report the case of a blind, nonambulatory, elderly man who was found alive in his home in an unresponsive state. Core body temperature at hospital was 24 degrees C (75 degrees F). At autopsy, punctate hemorrhages were present in the stomach mucosa. A 4- x 7-cm pituitary adenoma extended from a dilated sella turcica, obliterated the optic chiasm, and compressed the base of the brain in the region of the hypothalamus. Compression in this region of the brain would disrupt the temperature regulatory function of the hypothalamus and create an individual who would be susceptible to minor fluctuations in ambient temperature. The manner of death was designated as natural. This is an unusual presentation of a pituitary adenoma in the current era of advanced imaging techniques in which microadenomas are often detected and treated.
