Atypical autoerotic deaths.

So-called "typical" autoerotic fatalities are the result of asphyxia due to mechanical compression of the neck, chest, or abdomen, whereas "atypical" autoeroticism involves sexual self-stimulation by other means. We present five atypical autoerotic fatalities that involved the use of dichlorodifluoromethane, nitrous oxide, isobutyl nitrite, cocaine, or compounds containing 1-1-1-trichloroethane. Mechanisms of death are discussed in each case and the pertinent literature is reviewed.     

Wrapped to death. Unusual autoerotic death

Despite the large population of New Orleans, including many homosexual and transsexuals, there have been relatively few cases of autoerotic deaths. The case reported here is an interesting one as it includes a bizarre form of autoerotic behavior from the standpoint of the method used. There have been no deaths reported in the literature in which the victim died as a result of jeopardizing himself by enclosing his body into plastic with an airway out of his "cocoon" in the form of a snorkel tube. He was engaged in masturbation when he apparently lost his mouth piece or airway. He attempted to use a knife to cut himself out.     

Dental anesthetic death. An unusual autoerotic episode

The details of an unusual autoerotic death are presented; the postulated method of induction of cerebral hypoxia was inhalation of nitrous oxide from a dental anesthetic machine; the theme of dental anesthesia, presumably an elaborate bondage fetish, recurred in documentary material found at the scene.     

Rolled up to death. An unusual autoerotic fatality

Recently, an unusual case of autoerotic death in which a man died of hypoxia after having enclosed himself in plastic was reported in this Journal (1). We present a second case showing many similarities to the one published previously.     

Fatal hepatic failure following accidental tramadol overdose

A case of fatal overdose of tramadol is described, occurring in a 67-year-old man with painful rib fractures who accidentally ingested more than the recommended daily dose. The mode of death was acute liver failure due to fulminant hepatic necrosis. Post-mortem toxicology was negative apart from revealing a blood tramadol concentration well above the normal therapeutic range. This is the first report of fatal tramadol ingestion occurring in a therapeutic setting and also the first tramadol-related death where the mechanism was liver failure.     

Fatal bupivacaine intoxication following unusual erotic practices

A fatal drug overdose is described which involved unusual erotic practices. A 54-year-old male was discovered supine on the floor surrounded by sexual paraphernalia, syringes, and medications including three empty bottles of bupivacaine. Acute and chronic injection sites of the external genitalia with contusions, scarring, focal necrosis, and calcification were present at autopsy. Toxicology revealed femoral blood, heart blood, and vitreous bupivacaine concentrations of 3.8, 2.8 and 1.3 mg/L, respectively. The urine bupivacaine concentration was 11.4 mg/L. The cause of death was attributed to bupivacaine intoxication and the manner of death was accidental.     

Fatal intoxication following self-administration of a massive dose of buprenorphine

Several drug packages, including Subutex (high-dose buprenorphine, as sublingual tablets) boxes, were found near the corpse of a 25-year-old male drug addict, who apparently had committed suicide. The autopsy revealed a fatal respiratory depression. The toxicological investigations concluded that death resulted from massive burpienorphine intoxication. The determination of buprenorphine (BU) and norbuprenorphine (NBU) in all biological specimens was performed by liquid chromatography-electrospray mass spectrometry (LC-ES-MS) after hydrolysis (for solid tissues), deproteinization of the matrices, and solid-phase extraction of the compounds. Exceptionally high concentrations of BU and NBU were found in blood (3.3 and 0.4 mg/L, respectively), urine (3.4 and 0.6 mg/L), bile (2035 and 536 mg/L and brain (6.4 a nd 3.9 microg/g). The high concentration of BU (899 mg/L) and the absence of NBU in gastric liquid suggested oral intake. High concentrations of amino-7-flunitra/epam, the main metabolite of flunitra/epam, were also found in blood, urine and gastric liquid. This benzodiazepine may have been a co-factor in the toxic effects of BU.     

Fatal poisoning by protriptyline and haloperidol following an extreme overdose

In this paper the authors report on a case of lethal suicidal toxification with protriptyline and haloperidol after oral ingestion. Gas chromatographic and radioimmunologic investigations were used for quantitative determination of protriptyline and haloperidol in blood, urine, and tissues. The highest concentrations were found in lung and liver. These concentrations are discussed with reference to the cause of death.     

Fatal dissecting aneurysm of the internal carotid artery with delayed symptoms following facial impact.

A fatal dissecting aneurysm of the internal carotid artery occurred in a 16-year-old male following facial impact in an automobile accident. The patient showed no neurologic deficit until two days after the automobile accident, when he suddenly started having seizures and developed right-sided hemiparesis. There was no evidence of direct trauma to the neck externally or internally. The only injuries observed in the head and face were two skin lacerations in the chin area. His condition rapidly deteriorated, and he expired on the fourth hospital day. The gross and microscopic findings for the internal carotid artery are presented. The possible mechanisms for the vascular lesion and a review of the literature are discussed.     

Fatal decompression sickness following therapeutic hyperbaric environment (author's transl)

In Hannover/Germany in 1976 a so called "Society for Regenerative Hyperbaric Therapy" (Gesellschaft für Regenerative Uberdruck-Therapie) subjected 20 patients within two coupled multi-place chambers to a simulated hyperbaric environment, equivalent to a maximum of 4 ata, followed usually by gradual reductions of the pressure. The patients were of an average age of 67.2 years and were afflicted by various disorders. During one of the "dives" a patient developed air embolism of the central nervous system. During ensuing confusion of the chamber was opened suddenly, with resultant explosive reduction of the high pressure. This resulted in five letal accidents of decompression sickness. Post mortem examination revealed diffuse distribution of gas bubbles throughout the entire body. By elecronmicroscopy each bubble was covered by an osmiophilic coat. Post mortem findings are discussed and correlated with well-known and new clinical symptomes. These observations present for the first time fatal accidents of decompression sickness in humans, associated with hyperbaric air-therapy.     

Fatal intoxications in Denmark following intake of morphine from opium poppies

In Denmark it is legal to grow opium poppies for the production of poppy seeds and until 1986 for decoration purposes, too. Danish poppy capsules contain 0.3-5 mg morphine per capsule and the content of morphine in opium exuded from the capsules may amount to 24%. This has resulted in misuse as both fresh and dried poppy capsules have been used for the production of "opium tea". During the period 1982-1985, seven casualties occurred among drug addicts in Denmark which were solely or partly caused by these opium poppies.     

Pulmonary thromboembolism following calf cellulitis: report of an unusual complication of dog bite.

We report a case of a 75-year-old woman who died of pulmonary thromboembolism following a dog bite to the calf. The bite caused laceration of the skin and gangrenous cellulitis of leg soft tissues. Six days after hospitalization, the patient died suddenly, despite early antibiotic and heparin administration. Postmortem examination revealed extensive thrombosis of the deep veins of the calf and massive thromboembolism of the main pulmonary arteries.     

Fatal splenic rupture following Heimlich maneuver: case report and literature review

The most effective resuscitative procedure in choking by foreign bodies is the Heimlich maneuver, described for the first time by Henry Heimlich (1974) and recognized by the US Surgeon General (1985) as the "only method that should be used for the treatment of choking from foreign body airway obstruction." If performed correctly, this lifesaving maneuver is associated with rare complications, of which the most frequent are rib fractures and gastric or esophagus perforations. Other rare traumatic injuries such as pneumomediastinum, aortic valve cusp rupture, diaphragmatic herniation, jejunum perforation, hepatic rupture, or mesenteric laceration have been described.However, we are unaware of previous reports of splenic rupture after Heimlich maneuver. We present an interesting case of fatal hemoperitoneum due to a hilar laceration of the spleen following a correctly performed Heimlich maneuver.     

Accidental autoerotic deaths between 1978 and 1997. Institute of Legal Medicine, Medical School Hannover

Between 1978 and 1997 the Institute of Legal Medicine of the Hannover Medical School examined 17 fatal autoerotic deaths. The incidence for the Hannover region was 0.49 cases per million inhabitants per year. The victims included 17 men with an average age of 36.8 years; a peak in the age distribution was seen between 20 and 29 years. Twelve of the men were found by friends or family in a domestic environment, while other situations in which the victims were found included the victim's own car, a hotel room, a canal embankment, a public parking lot as well as the holding cell of the youth detention center. The men were of varying socioeconomic status and held a number of different types of jobs or still attended school. Five of the men were found completely nude, while five were only undressed below the waist. Four men wore women's clothes and two were fully clothed with exposed genitals. Besides women's clothes, other objects found at the scene included various types of sexual aids, including ropes, chains, metal bars, locks, sex magazines, condoms, plastic bags, rubber items, etc. In four cases blood alcohol levels between 0.1 and 2.5 per thousand (urine alcohol levels between 0.2 and 2.5 per thousand ) were found. Toxicologic examination revealed chloroform, ketamine, a propane-butane gas mixture in one case each, and in two cases cocaine and morphine. Causes of death included central paralysis after strangulation (seven cases), asphyxiation (4), subarachnoid hemorrhage (2), intoxication (1), hypothermia (1), left heart failure (1), and drowning (1). The history, findings at scene, and autopsy findings and, in individual cases, other investigations are of utmost importance to accurately reconstruct a fatal autoerotic accident.     

Fatal angioedema associated with captopril.

A markedly hypertensive, 70-year-old, black man had been on captopril for 2 years when he rapidly developed obstructive angioedema. The initial sign of difficulty in understanding his speech progressed to severe laryngeal and glossal edema over a 3 1/2 h period. His airway became obstructed less than a minute after arrival at the emergency room. Oral intubation was unsuccessful, and a difficult tracheostomy was too late to save the patient. The death was reported to the medical examiner because of its sudden and unusual nature. The risk of angioedema while on angiotensin converting enzyme inhibitor therapy has been noted previously in the clinical literature. Because of the sudden onset and possible confusion with an allergic reaction, this entity is brought to the attention of the forensic medical community.     

Fatal intoxications with chloral hydrate.

An alcoholic man, treated with chloral hydrate (CH) syrup to which he was dependent, was discovered comatose and in respiratory arrest. Death occurred on the ninth day of hospitalization following cerebral oedema. A woman, alcohol addicted, depressed, and epileptic was admitted in the Intensive Care Unit with heart and respiratory failure following CH absorption. She died three days later after a deep coma. In these two cases, CH intoxication was confirmed by toxicological analysis: CH and its major metabolite, trichloroethanol (TCE), were identified and determined in serum and urine using headspace-capillary gas chromatography-mass spectrometry. The concentrations measured were compared with those found in previously published fatalities. The analytical method used can be proposed for both clinical and forensic cases.     

Sudden death caused by coronary artery aneurysms: a late complication of Kawasaki disease

The authors describe three cases (two blacks and one Latin American) of sudden death caused by late complications of Kawasaki disease (mucocutaneous lymph node syndrome). At autopsy each heart contained multiple coronary artery aneurysms with luminal stenosis caused by intimal hyperplasia and thrombi. Although virtually all fatal cases of Kawasaki disease occur within six months of the onset of symptoms, there have been other reported deaths up to 14 years after the acute illness. The coronary artery aneurysms of Kawasaki disease may persist and cause death years after the acute illness.     

Fatal thrombosis of internal carotid artery following minor blunt trauma to the neck

Fatal traumatic thrombosis of the left internal carotid artery occurred in a 38-year-old man following minor blunt cervical trauma during an altercation. There was no external injury observed on the head, face, or neck. Neurologic deficit developed soon after the injury, which progressed to right hemiplegia. His condition deteriorated and he expired on the sixth hospital day. The gross and microscopic findings of the internal carotid artery are presented and the significance of minor cervical blunt trauma and the possible mechanism for the vascular lesion are discussed.     

Fatal hypernatraemia after laparoscopic treatment of hydatid liver cyst: medical and legal concerns of a rare complication

A case of fatal hypernatraemia after laparoscopic treatment of hydatid livers cysts is presented in order to highlight the risks associated with the implementation of newer techniques and the use of hypertonic saline as a scolecocidal agent in hydatid disease. Additionally this case raises some concerns on the importance of obtaining a patient's informed consent.     

Fatal respiration of liquefied petroleum gas.

We have found that an efficient method of providing evidence of lethal solvent abuse is to sample headspace above lung tissue and then perform cryogenically focused gas-liquid chromatography. In the case presented, the level of lethal agent in lung tissue was low, but the solvent was present in abundance in the pleural cavity. We conclude that the pleural cavity acts as an efficient trap for aspirated substances.
