Non-atherosclerotic coronary pathology causing sudden death.

Coronary atherosclerosis is responsible for >50% of all cases of sudden death and for 90% of sudden coronary death. Four cases encountered in routine autopsy evaluation at our institute in 2004 in which non-atherosclerotic coronary pathology was responsible for sudden cardiac death are reported. The cases of a 31-year-old man with epicardial coronary arteritis, a 57-year-old man with intramyocardial vasculitis, a 45-year-old woman with spontaneous coronary dissection and a 50-year-old man with vascular fibrosis are described. Searching for non-atherosclerotic coronary disease is relevant for both the clinician and the pathologist to prevent coronary causes of sudden death going unrecognised.

An unusual cause of fatal pulmonary embolism.

We report on a case of a fatal pulmonary embolism--an unexpected finding at autopsy of a 71-year-old man who had suffered from severe erosive gouty arthritis. Using morphological findings, medical history and histopathological results, we show the potentially devastating complications of this fairly common medical condition, occurring as a result of massive bone marrow erosion and detachment and finally leading to embolization of the lungs.

Acute flurazepam intoxication: a case report.

A fatality due to ingestion of flurazepam is reported. Flurazepam is a benzodiazepine, a widely prescribed hypnotic drug for use in sleep disorders. There are only few documented reports of the disposition of flurazepam in deaths due to overdose. A 68-year-old woman was found deceased at home with no evidence of trauma or asphyxia. Toxicologic analyses were performed and drug levels measured by means of gas chromatography coupled to mass spectrometry. The flurazepam concentration in each specimen was as follows: heart blood 2.8 microg/mL, bile 323 microg/mL, and urine 172 microg/mL. Presence of flurazepam into gastric content was observed too. Based on the autopsy findings, patient history, and toxicologic results, the cause of death was determined to be acute intoxication of flurazepam and the manner, suicide.

Death from renal cyst: spontaneous or traumatic rupture?

We report an unusual death of an apparently healthy 56-year-old male due to massive hemorrhage caused by rupture of an artery in the wall of a solitary renal cyst, possibly after a relatively minor trauma. Fatalities due to spontaneous or posttraumatic rupture of renal cysts are extremely rare but can represent a potential danger for people with acquired cystic kidney disease. Our report describes results of the forensic investigation and discusses possible mechanisms of the rupture.

Death due to railway-related suicidal decapitation: a case report.

In Italy, railway-related deaths give rise to extensive inquiries because it is mandatory for the public prosecutor to investigate the circumstances of death. For the railway embankment, normal traffic rules are not valid and the guilt of the engine driver usually cannot be proven. Consequently, these cases are very often declared as suicides without adequate evidence. Furthermore, there is a potential risk of confusion with homicide, body dismemberment or mutilation. Our medico-legal institutes are increasingly engaged with expert opinions on questions of accident, suicide or homicide because they lead to complications in the fields of insurance, criminal and civil law.

An acephalus acardius amorphous fetus in a monochorionic pregnancy with sex discrepancy.

Acephalus acardia is among the most severe malformations described in fetuses, with an incidence of about 1 in 35,000 births and is due to twin-to-twin transfusion syndrome, frequently occurring in monochorionic twin pregnancies. The severity of the syndrome depends upon the type of the anastomoses arising between the vascular networks of the two fetuses, usually configuring the 'twin reverse arterial perfusion syndrome'. No clear and univocal etiological explanation is known, though few cases with chromosomal abnormalities have been reported so far. In some cases the fusion of two or more separate placentae of dizygotic fetuses occurs, leading to monochorionic twinning. Few cases of acardius amorphous with complete autoptical examination have been described so far. We report a case of acephalus acardius amorphus fetus, showing features of extremely severe sistemic immaturity with very few structured organs. Defined external and autoptic examinations have been performed on the dismorphic twin, along with the histological examination of tissue samples. Kariotype analysis showed sex discrepancy between the twins, as a normal female kariotype had been detected in the acephalus acardius while the living co-twin was a normal healthy male. The analysis of the placenta showed the vascular anomalies leading to the twin-to-twin transfusion syndrome.

Infarct-related artery occlusion, tissue markers of ischaemia, and increased apoptosis in the peri-infarct viable myocardium.

AIMS: Unfavourable cardiac remodelling often complicates acute myocardial infarction (AMI) as a result of increased cardiomyocyte apoptosis. It is currently unclear whether ongoing or recurrent ischaemia is an independent determinant for increased apoptosis in peri-infarct viable myocardium. METHODS AND RESULTS: In order to assess the link between infarct-related artery (IRA) occlusion, ischaemia, and apoptosis, 30 subjects dying 7-120 days after AMI (16 with IRA occlusion and 14 with patent IRA) and five control subjects were selected at autopsy. Cardiomyocytes were defined as apoptotic if co-expressing TUNEL and activated caspase-3. Expression of both hypoxia-inducible factor-1 and cyclo-oxygenase-2 was assessed in the peri-infarct myocardium and considered as tissue markers of ischaemia. Evidence of ischaemia was significantly more frequent in cases with IRA occlusion (53%) than in cases with patent IRA (15%) or control hearts (0%, P=0.026). The finding of IRA occlusion and markers of ischaemia identified cases with higher apoptotic rates (ARs) in the peri-infarct viable myocardium [12.2% (8.2-14.0), P<0.001 vs. others], whereas IRA occlusion without ischaemia was associated with lower AR, not significantly different from patent IRA [3.0% (1.0-7.9) vs. 2.2% (1.0-5.8), respectively, P=0.42] CONCLUSION: Ischaemia in the peri-infarct viable myocardium is present in over 50% of subjects dying late after AMI with IRA occlusion, and it is associated with increased apoptosis. Relief of ischaemia after AMI may prove of benefit in preventing apoptosis and its consequences.

Medicolegal aspects of an unusual uterine perforation with multiload-Cu 375R.

Perforation of the uterus is one of the most serious complications associated with insertion of intrauterine contraceptive devices (IUD). According to recent studies, this lesion occurs in 0.87 per 1000 cases, but statistics generally fluctuate between 0.05 and 13 per 1000 insertions. "Primary" perforations occur at the time of IUD insertion, and "secondary," or delayed, perforations are usually assumed to be caused by reactive uterine contractions. We report an unusual case of uterine perforation, which occurred 9 days after the insertion of a Multiload-Cu 375 IUD. The criteria for differential diagnosis between primary and secondary complications are discussed, particularly from the perspective of medical malpractice cases.

Suicide by pencil.

We report an unusual suicide, committed with a common pencil. A 72-year-old male inflicted himself a penetrating thoracic wound while being hospitalized for a hip prosthesis operation. Although the patient was immediately operated, the cardiac injury appeared to be fatal. Cases of suicidal penetrating wounds of the anterior chest wall are rare and they are mostly inflicted by knives, glass fragments, or other sharp instruments. The potential danger of a pencil should be taken into consideration, especially in psychiatric hospitals and imprisonment facilities. We examined the legislation in Italy and Finland concerning the regulation of privacy in special care institutions.

Determination of carbohydrate deficient transferrin (CDT) with capillary electrophoresis: an inter laboratory comparison.

Carbohydrate deficient transferrin (CDT) is currently the most specific laboratory marker of chronic or sustained alcohol abuse. CDT is increasingly being used as a diagnostic tool in the areas employment, traffic safety and forensic medicine. In recent times, capillary electrophoresis (CE) has been proposed as a convenient tool for rapid, precise and accurate CDT determination, not only for research but also for routine analyses. Quite recently, commercial kits have been introduced which, reportedly, could simplify and standardize CDT analysis with capillary electrophoresis. The present work was aimed at testing the ruggedness of a capillary electrophoretic method based on a commercial kit (CEofix, Analis), by comparing the results obtained with different instruments in different laboratories, on a panel of sera randomly collected and exchanged. The results showed, notwithstanding few outliers, excellent correlation of the results obtained in the two laboratories (R=0.974). Also high concordance was found when results were classified as positive or negative on the basis of a cut-off (1.25%) established from a control group of teetotalers. In conclusion the present data support the usefulness of capillary electrophoresis for CDT determination for clinical, forensic and administrative diagnosis of chronic alcohol abuse.

Cocaine found in a child's hair due to environmental exposure?

We report a case of a 6-year-old boy who had been living with his parents, both cocaine smokers, and who was urgently admitted to hospital for general distress. Upon examination, cocaine and cocaine metabolites were detected in hair and urine samples. These toxicological findings most likely indicate that the child had passively consumed the drug when living in a heavily contaminated environment.

Increased apoptosis in remote non-infarcted myocardium in multivessel coronary disease.

BACKGROUND: Multivessel coronary disease after myocardial infarction is a major risk factor for unfavorable cardiac remodeling and death due to pump failure, but underlying pathophysiologic mechanisms are still uncompletely established. Post-infarction myocardial apoptosis has been recently implicated as a cause of ongoing cell loss leading to cardiac failure. Our aim was to assess the role of post-infarction myocardial apoptosis and pro-apoptotic factor expression in the non-infarcted remote myocardium of subjects with multivessel coronary disease. METHODS: Twenty-one males dying after recent myocardial infarction with permanent occlusion of the infarct-related artery were selected at autopsy. Apoptosis was assessed at viable myocardial regions remote from infarction by co-staining for in situ end-labeling of DNA fragmentation and cleaved caspase-3. Expression of pro-apoptotic factor bax and hypoxia-induced factor-1alpha was evaluated by immunohistochemistry. RESULTS: Subjects with multivessel disease (N=11) showed a significantly two-fold higher myocardial apoptosis in comparison to subjects with single vessel disease (N=10) (0.9% vs. 0.5%, p=0.013). Similarly, myocardial bax expression was increased in patients with multivessel disease (3.0% vs. 1.4%, p=0.029). Stratification for the number of diseased coronary vessels confirmed the association between extent of coronary disease and apoptotic rates (p=0.022). Even in subjects dying over 30 days after infarction multivessel disease remained predictive of enhanced myocardiocyte apoptosis at remote regions (p=0.033). CONCLUSIONS: Post-infarction myocardial apoptosis and bax expression in remote left ventricular regions are significantly increased in male patients with multivessel coronary disease in comparison to those with isolated infarct-related artery occlusion. These findings suggest that apoptotic cell loss in the viable non-infarcted myocardium, possibly due ongoing ischemia, may play a relevant role in the unfavorable clinical course typical of multivessel disease after myocardial infarction.

Adrenal Schwannoma. Report of two cases.

Adrenal tumours are frequently incidental discoveries, and their therapy is a subject of controversial discussions. Herein we describe two cases of adrenal schwannoma discovered during autopsy. The accidental observation of two benign schwannomas of the adrenal gland on asymptomatic patients led to the hypothesis that the real frequency of this type of lesion was underestimated. Furthermore, the adrenal origin of the superior retro-peritoneum schwannomas represents a diagnostic hypothesis to be considered when the original structure of the neoplasia can't be established.
