Lethal orphenadrine intoxication: report of a case.

A case of lethal orphenadrine intoxication is reported. Included are the anatomical and toxicological findings. Most conspicuous histologically was the centrilobular necrosis of the liver.     

Homicidal ethylene glycol intoxication: a report of a case

We report a case of a 75-year-old hypertensive, diabetic man who presented to the emergency room with symptoms and signs of nausea, acute intoxication, significant alteration in mental status with rapid neurologic deterioration, and blunt impact injuries sustained during a recent altercation with a 36-year-old female companion-caretaker. He denied a history of ethanol abuse or other recent toxic ingestion and had not been diagnosed with or treated for depression. Hospital laboratory tests revealed a metabolic acidosis and a negative urine toxicology screen. He was diagnosed with toxic encephalopathy with metabolic acidosis secondary to metformin. Despite treatments including hemodialysis, he expired after approximately 28 hours of hospitalization. A postmortem anatomic examination revealed recent blunt-impact injuries and cardiac and renal pathology. A subsequent histologic examination revealed the presence of calcium oxalate crystals in the kidneys and brain, in addition to cardiac and renal pathology. Comprehensive forensic toxicologic testing was performed on antemortem and postmortem samples and revealed lethal levels of ethylene glycol. The cause of death was as a result of acute intoxication by ethylene glycol with another condition of multiple blunt impacts to the head, trunk, and extremities. The manner of death was ruled as homicide. A trial by jury, involving the female companion-caretaker, resulted in her conviction, and she was sentenced to 23 years to life in prison. In this report, we present an unusual case of homicidal ethylene glycol intoxication in which legal proceedings have occurred.     

Pseudolaminar necrosis in cyanide intoxication: a neuropathology case report

We describe the gross and microscopic neuropathological changes in the brain of a 17-year-old male who died 4 days after being poisoned with cyanide. Previous reports indicate that following cyanide intoxication, the brain develops diffuse hypoxic/ischemic changes, predominantly of the basal ganglia. The case we describe here had similar features but in addition showed striking laminar necrosis of the cerebral cortex. This finding in cyanide poisoning has been previously demonstrated by neuroimaging, but not pathologically.     

Bupropion and alcohol fatal intoxication: case report.

A fatality due to the ingestion of bupropion and ethanol is presented. Bupropion and its metabolites were extracted from several tissues and identified using gas chromatography with nitrogenphosphorus and mass spectrometry detection. The concentrations of bupropion, hydroxybupropion and the erythroamino and threoamino alcohol metabolites in heart blood were 4.2, 5.0, 0.6 and 4.6 mg/l, respectively. The heart blood ethanol concentration was 0.27 g/dl. In addition, bupropion was distributed as follows: subclavian blood, 6.2 mg/l; bile, 1.4 mg/l; kidney, 2.4 mg/l; liver, 1.0 mg/kg; stomach contents, 16 mg and urine, 37 mg/l.     

Fatal acute alcohol intoxication in an ALDH2 heterozygote: a case report

On an evening in November, a 25-year-old man was found dead in his bedroom. There were many empty snap-out sheets for flunitrazepam tablets in the trash at his bedside. He had been beaten by a gang of young people earlier in the morning of the same day. At the medico-legal autopsy, although there were many bruises and/or abrasions on the whole body, only slight subdural hemorrhage was observed, and none of them was thought to be the cause of death. Flunitrazepam and its metabolites were not detected in his body fluid by gas chromatography-mass spectrometry (GC-MS). Marked lung edema and a severe congestion of organs were observed. His blood alcohol concentration from the femoral vein was 2.00 mg/ml. Fatal cases of acute alcohol intoxication usually have shown higher alcohol concentration (2.25-6.23 mg/ml). Although the genotype of aldehyde dehydrogenase 2 (ALDH2) has not previously been mentioned as a contributing factor in determining the cause of death, in this case the genotype of ALDH2 was ALDH2*1/2 and thus is important. Those who possess the ALDH2*2 gene show high concentrations of acetaldehyde (AcH) at even comparatively lower alcohol levels. Consequently, the cause of death was considered to be acute alcohol intoxication including AcH poisoning.     

Fatal intoxication by dextromethorphan: a report on two cases

A report is given of two young people who died after intake of dextromethorphan, one by suicide and the other for uncertain reasons. To our knowledge this is the first reported fatal intoxications with this drug.     

Fatal intoxication due to tramadol alone: case report and review of the literature

Poisoning may also lead to both coma and multiple organ failure, also in youngsters without a known major medical history. As not all toxic agents are routinely screened when a poisoning is suspected, it is useful to consider less frequently encountered poisons in certain cases. We describe the occurrence of asystole and multiple organ failure which occurred in a young man after a suspected tramadol overdose. The tramadol concentration on admission in the ICU was indeed 8 microg/ml (mg/l), far above the therapeutic range. Subsequently, the patient developed severe acute liver failure, finally leading to death. Post-mortem toxicology did not reveal any other poison responsible for this unfavourable course as only very high serum and tissue tramadol and desmethyltramadol concentrations were found. Only a few fatal poisonings attributable to tramadol alone, as observed in our case, have been reported. An overview of these cases is presented.     

The general toxicology unknown. II. A case report: doxylamine and pyrilamine intoxication

A general toxicology unknown case is presented to demonstrate our systematic approach. A 20-year-old male was found dead with multiple suicide notes. Overdose was suspected but substances were not known. Blood alcohol was negative. Urine was analyzed by enzyme-multiplied immunoassay technique and was negative for all drugs assayed. Urine was then extracted with ethyl acetate:hexane (1:1) at pH 10 and back-extracted into 1.0N sulfuric acid. The acidic layer was adjusted to pH 10, and re-extracted with ethyl acetate:hexane (1:1). The residue was analyzed by gas chromatography (GC) on a 3% OV-101 column. It was found to be negative for all commonly screened substances. However, several unknown peaks were observed. Electron impact mass spectra of these unknown peaks were obtained and searched for in our computer library of more than 25000 mass spectra. These unknown peaks were identified as doxylamine and pyrilamine by gas chromatography/mass spectrometry. The base peak and molecular ion for pyrilamine were at m/z 121 and 285, respectively. The base peak for doxylamine was at m/z 58. No molecular ion was observed for doxylamine. Both doxylamine and pyrilamine are antihistamines, but are promoted and used in the management of insomnia. Quantitation was performed on a GC using dexbrompheniramine as an internal standard. Blood concentrations for doxylamine and pyrilamine were 0.7 and 7.0 mg/L, respectively. Concentrations in other tissues were determined. Death was caused by combined doxylamine and pyrilamine intoxication; the manner of death was suicide.     

Case report of a fatal intoxication by citalopram

Citalopram is an antidepressant drug within the group of the selective serotonin reuptake inhibitors (SSRI). It is widely prescribed both in Europe and in United States, and it has always been considered a "safe" drug as pure intoxication with lethal outcome is rare, and most cases of overdose, even with high doses of citalopram ingested, are reported to have an uneventful course.We report the case of a young woman found dead at home. She had been prescribed citalopram by her family doctor 3 weeks before her death for a depressive syndrome. Police found in her house 3 empty blister packages of 28 citalopram tablets (20 mg) and 2 bottles of citalopram oral solution (4%, 15 mL each). The autopsy findings were unremarkable. Nasal swabs, blood from femoral vein, urine, bile and tissue samples were collected for toxicologic investigation. Citalopram separation was performed by solid/liquid method, using Bond-Elute columns. The extracts were analyzed by GLC and GC/MS methods. The toxicologic analysis showed high levels of citalopram in all the examined fluids and tissue samples (blood concentration: 11.60 mg/L). No other drugs and alcohol were detected. Our data confirm that if no other drug is involved, fatal complications occur only after ingestion of very high doses. However, there is no predefined "toxic dose," and the conditions under which the overdose occurs can be very important. We report the exact concentrations of the citalopram in the organs, and wethink that this can be useful in the cases where the blood samples were not available (ie, carbonized or decomposed body).     

Human cannibalism: a case report

Human cannibal cases are relatively rare in modern civilized societies. We report a single case of familial cannibalism that occurred in Oklahoma in 1977. The investigation posed unique problems in pathology, psychiatry, criminalistics, and serology.     

False rape: a case report

A 16-year-old girl was admitted to the emergency department for sexual assault. The forensic examination revealed genital lesions of an age that were incompatible with her statements. She also presented extragenital lesions that resembled self-inflicted lesions. The reports of false rape allegations in the literature have all dealt with the motivations of the false victims. This case report is a reminder that an allegation of rape can be considered only on the basis of proof and not on speculation.     

Caffeine fatality: a case report

A case of fatal caffeine toxicity due to suicidal ingestion of a "look-alike" illicit drug is reported. Caffeine concentrations were determined by high pressure liquid chromatography (HPLC) with the brain having the highest level reported in the literature to date. Also, the blood concentration of caffeine was one of the highest among the cases reported. A literature review of caffeine fatalities is presented.     

Accidental dichloromethane fatality: a case report

A case of accidental dichloromethane poisoning by inhalation is presented. It is of interest that carboxyhemoglobin levels were within the normal range, suggesting that the narcosis and respiratory depression were due to the direct effect of DCM on the central nervous system. The accidental death was attributed to improper ventilation of vapors in the working area.     

Acute intoxication with orphenadrine and clozapine.

This report describes a fatal intoxication with two different drugs: clozapine and orphenadrine. A 38-year-old man was found dead in the bedroom of his residence. Near the body were found various empty pharmaceutical boxes, employed in schizophrenic therapy, two of them containing clozapine and orphenadrine. High concentrations of clozapine and orphenadrine detected in blood, urine and gastric content were related to death. These compounds were identified and quantitated by liquid-liquid extraction followed by gas chromatographic/mass spectrometry (GC/MS) analysis.     

An Indian mummy: a case report

A case of mummification occurring in northwest India (Chandigarh) is described. A middle-aged man developed an abscess on his back and was treated by a mystical man who did not allow him any food or water. After a few days the patient died. On the advice of the mystical man the body was kept in a room which was made hot and dry. The police discovered the body after 2 years. A postmortem examination was conducted and findings are reported.
