Esophagoaortic perforation by foreign body (coin) causing sudden death in a 3-year-old child.

We report an extremely unusual consequence to foreign body ingestion in a case of a 3-year-old boy who died suddenly and at autopsy was found to have an esophagoaortic fistula. This fistula was caused by a coin which lodged posteriorly and eroded through the esophagus into the aorta. Serious complications following foreign body ingestion are rare and include stricture formation, intramural abscess, and the formation of fistula tracts. This case illustrates the potentially unpredictable behavior of impacted foreign bodies. The child's parents were initially suspected of child abuse based on the terminal hemoptysis.     

Non-diagnosed pulmonary hyalinizing granuloma (PHG) as a cause of sudden unexpected death

Pulmonary hyalinizing granuloma (PHG), a very rare benign tumour of the lungs, was first reported in 1977. We present a PHG of a 32-year-old woman from Yemen who collapsed 1 day after her arrival in Germany. Tuberculosis was suspected and the health authorities nearly closed part of one of the major international airports in Europe. However, this drastic measure was avoided by autopsy and a correct interpretation of the solid-elastic and well-circumscribed lung tumour as not characteristic for tuberculosis. Although the final diagnosis of PHG was only achieved after histology, this case strongly illustrates the necessity of a profound morphological training of forensic physicians.     

Non-diagnosed pheochromocytoma as a cause of sudden death in a 49-year-old man: a case report with medico-legal implications

Pheochromocytomas are known to be rare causes of sudden death. A 49-year-old man with a medical history of arterial hypertension and diabetes mellitus complained about nausea and malaise in the morning. During the day his condition deteriorated. He went to the emergency department, where he was given intravenous drugs against nausea and was sent home. On the way back, his condition deteriorated dramatically so that his wife drove back to the emergency room, where he collapsed and sustained cardiac arrest; resuscitation efforts were unsuccessful. Autopsy revealed a large tumour of the left adrenal gland. The strong suspicion of pheochromocytoma was confirmed by histology, immunohistochemistry and biochemical investigations. An acute hypertensive crisis, caused by the hitherto unknown pheochromocytoma was ascertained as the cause of death. The morphological findings are presented, the difficulty to diagnose pheochromocytoma and the medico-legal implications are discussed.     

Homicide as a cause of the sudden infant death syndrome

The homicidal asphyxiation of a 10 1/2-month-old male infant and the attempted asphyxiation of his 4-month-old sibling, documented by parental confession, is presented as evidence that murder may sometimes be mistaken as sudden infant death syndrome (SIDS). A review of the literature of the relationship between murder and SIDS deaths reveals the suspicions of some physicians but few published cases; this reflects not only the difficulties of making a determination of murder by suffocation, since no injuries may be present, but also a lack of awareness among physicians who must evaluate infant deaths. It is recommended that murder should be considered in the differential diagnosis of sudden, unexpected death in infants and that the autopsy should include full-body x-rays and at least an initial look at the social history of the child.     

Asplenia as a cause of sudden unexpected death in childhood

Sudden unexpected death in childhood is rare. The commonest causes of such deaths are a result of fulminating infections of the respiratory or nervous systems. Other causes include unsuspected congenital abnormalities of the heart, acute metabolic disorders, and rarities such as internal hemorrhages and pulmonary thrombosis. Recognition of children with congenital asplenia who are otherwise normal but have an increased susceptibility to overwhelming sepsis is extremely difficult. We reviewed 1763 autopsy files from our institution over 5 years (1990-1995), of which 293 were classified as pediatric cases. The vast majority of the cases were stillbirths and deaths within the first year of life as a result of complex congenital anomalies. Four cases of asplenia were identified in our entire series, 3 of which were of the congenital syndromal variety and 1 of which was a case of isolated sporadic congenital asplenia. All 4 cases of asplenia were analyzed in detail with respect to autopsy findings and cause of death. Severe complex cardiac malformations were present in the congenital syndromal asplenia patients; these other malformations contributed significantly to their death. In this report, we discuss in detail the autopsy findings in a previously healthy 4-year-old girl who presented with a brief 8-hour history of being unwell and died within 4 hours of admission into the hospital. She had sporadic, isolated congenital asplenia complicated by high-grade type 6B pneumococcemia and acute bilateral adrenal hemorrhage (Waterhouse-Friderichsen syndrome). Previously healthy children who clinically deteriorate very rapidly should have a blood smear done as part of their clinical workup. The detection of Howell-Jolly bodies on a peripheral blood smear can be an indicator of asplenia, and this diagnosis can be confirmed by medical imaging of the abdomen. Such steps may aid in the aggressive management of isolated congenital asplenia and thereby avert untimely death.     

Dicyclomine in the sudden infant death syndrome (SIDS)--a cause of death or an incidental finding?

We report a case of a small infant apparently dying of the Sudden Infant Death Syndrome (SIDS) with a postmortem blood dicyclomine level of 200 ng/mL. Review of the literature and the comparison with blood dicyclomine values from four rabbits given equivalent doses suggests that a blood dicyclomine value of 200 ng/mL probably is in the therapeutic range for infants. Although safely used for years for infantile colic, recently, the administration of dicyclomine has been related to acute episodes of apnea, seizures, and coma. In the absence of those acute reactions, we feel that a 200-ng/mL blood dicyclomine level in a child dying of apparent SIDS should not prevent categorization of the death as SIDS.

Myocardial dysplasia of the right ventricle (Uhl's anomaly) as a possible cause of sudden, unexpected death

Partial absence and fatty replacement of the myocardial compacta of the right ventricular wall was observed in five young male adults, four of whom died suddenly and unexpectedly and one in a car accident. In one of these cases there was only one coronary orifice. Four cases of the so-called Uhl anomaly had histological findings indicating dysmorphic myocardial cells associated with minimal lymphohistiocytic infiltrates within the fatty tissue. In one case, chronic destructive inflammation was a prominent feature. Marked dysmorphic alterations in the myocardial fibers suggested the occurrence of arrhythmic episodes as the main cause of sudden heart failure and death.     

Isolated myocarditis as a cause of sudden death in the first year of life

A series of three cases of isolated myocarditis, presenting as sudden death in infancy, occurred over a period of 3 months. This prompted a review of the autopsy records of the Children's Hospital of Winnipeg. Over a period of 40 years, 24 cases of isolated myocarditis were traced from 3196 autopsies. Most (21 of 24) cases of isolated myocarditis occurred in infants less than 12 months of age. In 16 of the infants there were either no antecedent clinical signs (sudden deaths), or a short clinical history of less than 24 h duration. Heart weights, however, were greater than the 99th percentile of published normals in three infants and above the 95th percentile in a further 16 infants. Areas of hypertrophied fibres were seen even in infants with a short history. These latter findings suggest that a latent phase of myocarditis may exist. The responsible pathogens were identified very rarely, due to a lack of suspicion of the existence of myocarditis, and it is suggested that samples of myocardium should be submitted for virologic examination in all cases of sudden death in the first year of life.     

The witness in German criminal case (a contribution from the legal, psychological and psychiatrical view) (author's transl)]

The judgement of adult witnesses in particular cases, as sufficiently made clear by the described special case, is at least as necessary as a specialist's opinion of child testimony. Furthermore, it should be noted that the present modus of criminal proceedings does not allow for adequate objectivation possibilities of testimony of witnesses. Thirdly, it should be pointed out that at least for the so-called key witnesses a specialist's examination, i.e. by a psychiater and a psychologist is of great importance; it seems at least necessary that in problematic cases the specialist or the court should have the possibility to interrogate the witness to the exclusion of the public. It also seems of utmost importance to extend the judge's knowledge in the field relevant to the subject during his university education and also during his further professional instruction in order to enable him to identify problematical cases in time and decide on calling upon an adequate specialist.     

Subendocardial small infarct in the superior ventricular septum as a cause of sudden death

In autopsy files from April 1999 to April 2001, five cases showed macroscopic subendocardial small infarct above 1 cm diameter in the superior ventricular septum (SVS) near the atrioventricular (AV) junction, and all five were finally considered to be sudden cardiac death after full investigation. All these small infarcts in these Japanese patients were located at the posterior site of the SVS, an area mainly nourished by branches which ramified from the AV node artery and which branched from the right coronary artery (RCA). Four of the five showed acute (A) or subacute (SA) foci in or around the healed (H) lesion and surviving myocytes were visible in infarcts, in all cases, which suggested a recurrent or chronic prolonged ischemia in the territory. Four of the five had a significant stenosis of the RCA and in the other one, there was an anomalous origin of the RCA. As all five had also small artery disease in the SVS, small infarct of the posterior SVS may have formed by hemodynamic impairment in the territory of the AV node artery caused by RCA disorders. We consider the evidence of macroscopic small infarct of the posterior SVS greatly aids in determining the cause of sudden death in forensic autopsy and may be notable lesion for discussing the pathogenesis of sudden cardiac death with RCA disorder.
