In spite of the arterial embalming generic eriacta 100mg with visa impotence gel, a large quantity of blood mixed with embalming ﬂuid was still present in the heart and aorta cheap generic eriacta canada short term erectile dysfunction causes. They showed an interesting pattern of multiple hospital and emergency room 534 Forensic Pathology admissions over a 1-year period for severe hypoglycernia cheap eriacta 100 mg fast delivery erectile dysfunction caused by guilt. At the time of all of these inci- dents, the deceased had apparently been drinking and had been “found” unconscious or seizing by his wife. Because of this history, insulin levels were performed on the blood obtained at autopsy in spite of the fact that it had been contaminated with embalming ﬂuid. Subsequent investigation disclosed that the patient’s wife was diabetic and on insulin. The cause and manner of this death were certiﬁed as acute insulin overdose, homicide. Insulin is produced in the beta cells of the islets of Langerhans by the enzymatic cleavage of the precursor polypeptide proinsulin. For every mol- ecule of insulin formed, a corresponding molecule of C-peptide is formed. Classically, diabetes has been treated by the administration of insulin obtained either from cattle or swine. The administration of insulin from either cattle or swine may result in the production of antibodies to these forms of insulin. Such anti- bodies, however, are not as common as one would expect, due to newer methods of puriﬁcation of insulin. Thus, individuals who have been taking insulin of animal origin for many years may not have antibodies. In the case seen by the author, the mea- surement of blood insulin was possible even when embalming ﬂuid had contaminated the blood. This was conﬁrmed by a second death in which a nurse accidentally administered an overdose of insulin and the body was also embalmed before the case was reported to the medical examiner’s ofﬁce. In a limited series of experiments, blood was spiked with both embalming ﬂuid and insulin. Blood glucose levels postmortem are of no help in the diagnosis of hypoglycemia, because there is release of glucose postmortem. Thus, one might get normal or elevated levels of glucose in postmortem blood in an overdose from insulin. The vitreous is of no help either, because abnormally low values of glucose in the vitreous have no signiﬁcance. If the increase in concentration of insulin in the blood is caused by endogenous production either by the pancreas or a tumor, then the concentration of C-peptide should theoretically be elevated. Thus, if one ﬁnds high insulin and high C-peptide, one assumes that the insulin is endogenous. If, however, one sees high concentrations of insulin Interpretive Toxicology: Drug Abuse and Drug Deaths 535 and normal or depressed concentrations of C-peptide, then one would con- clude that the insulin is of exogenous origin, that is, it was administered. In addition, C-peptide is very unstable and analysis for it in postmortem blood is not satisfactory and, in fact, in our experience, is of no use. In the cases that have just been described, insulin levels were also done on urine and bile. The signiﬁcance of this was unknown by the author, so he had routine tests for insulin levels performed on urine and bile of indi- viduals who died of trauma, that is, homicide and accident victims. The levels of insulin in the urine or bile in these cases showed tremendous variation. Antidepressants Drug overdose is the second most common method of suicide in the U. This has changed dramatically in the past 20 years such that deaths caused by barbiturates are now relatively uncommon. The most common family of drugs used in suicides now are the antidepressants, speciﬁcally, the tricyclics. The ﬁrst included amitriptyline, nortriptyline, imipramine, desipramine, and dox- epin; the second, amoxapine, trazodone, bupropion and maprotiline and the third venlafaxine, nefazodone and mirtazapine. There is allegedly an increased incidence of seizures in epileptics taking the tricyclics. The therapeutic, toxic, and overdose concentrations of the ﬁrst two generations of these drugs are listed in Table 23. A number of individuals have contended that there is signiﬁcant post- mortem redistribution of the tricyclic antidepressants and that concentra- tions of these drugs in postmortem blood do not accurately reﬂect their perimortem concentration. Apple and Bandt contend that only liver levels of the tricyclic antidepressants should be used for diagnosis of overdoses. However, we believe that, in only rare instances, would there be sufﬁcient release of the drug postmortem so as to even suggest that a case was a fatal overdose when it was not, if one uses the levels in Table 23. Even in the paper by Apple and Bandt, in the nine cases of fatal overdoses of tricyclics, the concentration of the tricyclic and its major metabolite in the 536 Forensic Pathology Table 23. In contrast, in the deaths from other causes in individuals taking therapeutic doses of tricyclic antidepressants, the range was 0. Most of the aforementioned discussion is academic, because the authors recommend that blood for toxicologic analyses be obtained from either the femoral or subclavian vessels. Mixed Drug Overdose After the tricyclic antidepressants, the “drug” most responsible for suicidal deaths in our experience (though it has been the ﬁrst in other series) is not a drug, but a combination of drugs, or mixed drug overdose. The two most common drugs involved in mixed drug overdoses are alcohol and the tricyclic antidepressants, followed by the benzodiazepines, most commonly diazepam. The benzodiazepines, used principally as anti-anxiety and muscle relaxant agents, are probably one of the most benign groups of drugs on the market if taken alone. Mixed with alcohol or other drugs, however, they can con- tribute to a fatal outcome. Except for phenobarbital used in the treatment of epilepsy, these drugs are rarely encountered by the forensic pathologist. In discussing barbiturate overdoses, one has to mention the concept of “drug automatism. If one accepts this theory, some deaths caused by overdose that are classiﬁed as suicide should be classiﬁed as accident in that the drugs were taken without intention, after the ﬁrst dose produced confusion. It is essentially an unproven hypothesis and should be considered just another one of the theories put forth by people in an effort to change a suicide ruling to accident.
