Abstract
Sudden death due to unknown cardiac disease in children is an unusual occurrence. An apparently healthy 12-year-old boy without any physical restrictions collapsed suddenly and died despite cardiopulmonary resuscitation. The main autopsy finding was extensive scarring of the myocardium, especially the interventricular septum. This extensive scarring was exceptional for the young age. Histologically, replacement-type fibrosis with patchy lymphomonocytic infiltrate and infiltration by macrophages were observed. The case was diagnosed as chronic myocarditis, which may have progressed to dilated cardiomyopathy with inflammation or inflammatory cardiomyopathy.

Cardiovascular pathology in 2 young adults with sudden, unexpected death due to coronary aneurysms from Kawasaki disease in childhood. Cardiovasc Pathol 2015; 24:310-6. [PMID: 25791439 PMCID: PMC4547904 DOI: 10.1016/j.carpath.2015.02.006] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2014] [Revised: 02/18/2015] [Accepted: 02/18/2015] [Indexed: 12/17/2022] Open
Abstract
PURPOSE Coronary artery aneurysms (CAA) may remain silent after Kawasaki disease (KD) until adulthood when myocardial ischemia can lead to sudden death. We postulated that there would be young adults with sudden, unexpected death due to CAA from KD who would have a state-mandated autopsy performed by the San Diego County Medical Examiner's Office (SDCMEO). METHODS We reviewed all autopsy cases <35years of age from 1997 to 2012 at the SDCMEO with a cardiovascular cause of death (n=154). RESULTS We found 2 cases meeting inclusion criteria. Case 1 was a 22-year-old Korean male with chronic ischemic changes due to a partially occluded and diffusely calcified 15mm aneurysm at the bifurcation of the left main coronary artery. Interview of the mother revealed that this patient had been diagnosed with KD complicated by giant aneurysms at age two years. Case 2 was a 30-year-old Hispanic male with myocardial infarction due to thrombosis of a calcified left anterior descending artery aneurysm. Histologic findings included diffuse myocardial fibrosis and a recanalized aneurysm in the right coronary artery. Interview of the family revealed a KD-compatible illness in childhood. Immunohistochemical staining showed expression of transforming growth factor β pathway molecules in the aneurysmal arterial wall. CONCLUSIONS In a medical examiner's office serving a population of approximately 3 million people, 2 of 154 (1.3%) cardiovascular deaths in persons <35years were attributed to cardiovascular complications of KD in childhood. Antecedent KD should be considered in the evaluation of all cases of sudden, unexpected death in young adults.

Abstract
There has been an increase in cycling in Australia. This means that more cyclists are at risk of injuries, which account for a proportion of transport-related fatalities. In this study, all cyclist fatalities from 2002 to 2013 in South Australia where post-mortem examinations were performed were investigated. There were 42 deaths representing 3% of the total road fatalities over the same time. Of this total number of cases, 13 deaths (31%) involved collapse (mostly natural causes from an underlying medical condition) and 29 (69%) resulted from trauma. There were no cases of hyperthermia. Of the decedents 95% were male, and the mean age at death was 47 years. Fatal incidents were more likely to occur during April and November, and on a Monday. However, statistical analysis was not possible due to the small number of cases. Fatalities (traumatic and collapse) predominantly occurred whilst the cyclist was riding (86%). The majority of riding fatalities were as a result of collision with vehicles (81%). Drugs (including alcohol) were detected in two (15%) of the 13 cases of the collapses, and in seven (26%) of the 27 trauma cases tested. In trauma cases, death was most often due to multiple injuries. The most frequent area for injury was the head (found in 90% of traumatic deaths). Despite the increasing numbers of cyclists on South Australian roads over the last decade, death rates have trended downwards suggesting that road safety campaigns and the provision of more dedicated bicycle lanes have had a positive outcome.

Crawling to the finish line: why do endurance runners collapse? Implications for understanding of mechanisms underlying pacing and fatigue. Sports Med 2014; 43:413-24.

Abstract
Effective regulation of pace enables the majority of runners to complete competitive endurance events without mishap. However, some runners do experience exercise-induced collapse associated with postural hypotension, which in rare cases results from life-threatening conditions such as cardiac disorders, cerebral events, heat stroke and hyponatraemia. Despite the experience of either catastrophic system failure or extreme peripheral muscle fatigue, some runners persist in attempting to reach the finish line, and this often results in a sequence of dynamic changes in posture and gait that we have termed the 'Foster collapse positions'. The initial stage involves an unstable gait and the runner assumes the 'Early Foster' collapse position with hips slightly flexed and their head lowered. This unstable gait further degrades into a shuffle referred to as the 'Half Foster' collapse position characterized by hip flexion of approximately 90° with the trunk and head parallel to the ground. At this point, the muscles of postural support and the co-ordination of propulsion begin to be compromised. If the condition worsens, the runner will fall to the ground and assume the 'Full Foster' collapse position, which involves crawling forwards on knees and elbows towards the finish line, with their trunk angled such that the head is at a lower angle than the hips. Upon reaching the finish line, or sometimes before that, the runner may collapse and remain prone until recovering either with or without assistance or medical treatment. The Foster collapse positions are indicative of a final, likely primordial, protective mechanism designed to attenuate postural hypotension, cardiac 'pump' insufficiency or cerebral blood flow deficiency. Continuing to attempt to reach the finish line in this impaired state is also perhaps indicative of a high psychological drive or a variety of neurological and psychological pathologies such as diminished sensitivity to interoceptive feedback, unrealistic situational appraisal or extreme motivational drives. A better understanding of the physiological, neurological and psychological antecedents of the Foster collapse sequence remains an important issue with practical implications for runner safety and theoretical understanding of collapses during exercise.

Sudden unexplained cardiac arrest in apparently healthy children: a single-center experience. Pediatr Cardiol 2013; 34:639-45.

Abstract
This study aimed to determine the causes of sudden cardiac arrest (SCA) in apparently healthy children at a single center in the era of primary prevention (screening questionnaire [SQ]) and secondary prevention (automated external defibrillator [AED] and the automated implantable cardioverter defibrillator [AICD]). Any child 0 to 18 years of age without prior known disease, except for attention deficit disorder, who underwent out-of-the hospital cardiopulmonary resuscitation was included in the study as a SCA subject. A retrospective chart review was used to evaluate the efficacy of the SQ, electrocardiogram (ECG), chest roentgenogram (CXR), and echocardiogram. The findings showed that for 44 of 6,656 children admitted to intensive care with SCA, an AED was used for 39%, an AICD was placed in 18%,and survival to hospital discharge was 50%. The etiology for SCA was identified in 57% of the cases, mostly in those older than 1 year, and the majority of these had a cardiac etiology (50%), whereas 7% had rupture of an arteriovenous malformation. Stimulant medication use was seen in 11% of the SCA subjects. In the best-case scenario of hypothesized primary prevention, a prior SQ, CXR, ECG, or echocardiogram may have detected respectively 18, 9, 23 and 16% of the at-risk cases, and 32% of the cases may have been detected with ECG and SQ together. Based on a historical control cohort, a positive ECG was significantly higher in the children with SCA (p = 0.014). An ECG together with a screening SQ may be more effective in identifying children potentially at risk for SCA than an SQ alone.

Abstract
Despite the fact that brain arteriovenous malformations (BAVMs) are a possible cause of sudden and unexplained death, very few papers have discussed their importance in the forensic context. BAVMs consist of tangled masses of tortuous arteries and veins devoid of intervening capillaries that frequently extend from brain parenchyma into the subarachnoid space. Apart from BAVMs, three major groups of vascular malformations of the brain are known: cavernous hemangioma, venous angioma, and capillary telangiectasia. BAVMs and cavernous hemangioma often cause hemorrhages, while venous angioma and capillary telangiectasia are typically asymptomatic. Presented here is the case of a 14-year-old girl who died from a ruptured BAVM. The present case is a reminder that the forensic pathologist should be able to recognize BAVMs and to differentiate it from other types of vascular malformations. Although rare, it is a cause of sudden death not to be overlooked, especially in children.
