High urine ethanol and negative blood and vitreous ethanol in a diabetic woman: a case report, retrospective case survey, and review of the literature.

Several studies have shown that ethanol can be produced in urine infected with yeast or bacteria in vitro. We present the unusual case of a diabetic woman in whom ethanol was produced in her urine in vivo. The decedent was a 19-year-old woman who was noncompliant with her diabetes treatment. She presented to a local hospital in severe diabetic ketoacidosis and died shortly thereafter. Upon arrival at the hospital, a blood glucose of 553 mg/dL was detected. A urinalysis was positive for ketones (> 80 mg/dL), glucose (> 1000 mg/dL), and large budding yeast forms. A drug screen performed on the urine was positive for ethanol. At the coroner/medical examiner office, an autopsy was negative for significant anatomic findings. Toxicology analysis revealed a urine ethanol level 0.32 g/dL, although no ethanol was detected in blood or vitreous samples. A urine gram stain and culture identified Candida glabrata. A retrospective case review of all deaths related to diabetes examined at the coroner/medical examiner office from 1986 to 2003 did not reveal other cases with similar findings. This case of a noncompliant, juvenile-diabetic woman illustrates a rare finding of apparent in vivo glucose fermentation by C. glabrata to form ethanol in the urine. This case also highlights a potential difficulty in toxicologic analysis and interpretation using urine only.

Unexplained sudden death and the likelihood of drug abuse.

The common history of drug abuse in adults with an undetermined cause of death has led us to hypothesize that chronic drug abuse increases the risk of sudden death. To begin evaluating this hypothesis, we conducted a retrospective case-control study of 61 decedents whose cause of death remained undetermined following autopsy matched one to one to a control group of pedestrians or passengers killed in motor vehicle collisions. In 21 pairs, the case subject had evidence of drug abuse but the control did not, and in 5 cases the reverse was true. Analysis showed that individuals with an undetermined cause of death are 4.2 times more likely to have evidence of drug abuse than are victims of a motor vehicle collision.

Investigation of elderly deaths in nursing homes by the medical examiner over a year.

Despite death being one of the most common reasons for discharge from a nursing home, fewer than 1% of nursing home resident deaths are autopsied. To evaluate our role as medical examiner in nursing home deaths, we conducted a retrospective review of all decedents in Jefferson County, Alabama, for the year 2001. Death certificate data indicate that 995 deaths occurred in nursing homes in Jefferson County in 2001. Of those 995 deaths, 119 (12%) were reported to the Jefferson County Coroner/Medical Examiner Office. Jurisdiction was accepted in 5 cases in which the circumstances already made clear that the death was a nonnatural event. In the remaining 96% of nursing home deaths reported to the medical examiner, the statements of the reporting person were taken to be true concerning the expected nature of the death. An independent scene evaluation was provided by a police officer or paramedic in 82% of the cases reported to the medical examiner's office. Elderly individuals, as a group, are expected to die, but the death of a particular elder may or may not be expected. In our jurisdiction, only 12% of all nursing home deaths are reported to our office, and only 4% of reported deaths are actively investigated. Actively investigating each nursing home death would overwhelm the resources currently available to our office. We advocate the study and development of criteria to aid in determining whether the death of an individual elder is sudden and unexpected.

Polydrug fatality involving metaxalone.

A 29-year old female with a history of depression was found dead in a hotel room. The death scene investigation found empty pill bottles and an empty liter bottle of wine. Metaxalone, a centrally acting muscle relaxant, along with citalopram, ethanol, and chlorpheniramine were identified in the postmortem samples and quantitated by gas chromatography-mass spectrometry. The concentration of metaxalone in femoral vein blood was 39 mg/L. The heart blood concentration was 54 mg/L. Femoral vein blood concentrations of citalopram and chlorpheniramine were 0.77 mg/L and 0.04 mg/L, respectively. Ethanol levels were 0.13 g/dL in vitreous and 0.08 g/dL in heart blood. Other tissue samples were also analyzed. The authors consider the metaxalone concentrations toxic and potentially fatal. The citalopram concentrations were lower than those reported in fatal cases for this drug alone. Death was ascribed to polydrug abuse/overdose with metaxalone a major contributor. This represents the first reported case to our knowledge in which a metaxalone overdose significantly contributed to death.

Management of a patient with HIV infection-induced anemia and thrombocytopenia who presented with thrombotic thrombocytopenic purpura.

A 32-year-old male presented with fever, mental status changes, renal dysfunction, cytopenias and hemolysis. His platelet count was 14,000/microL, hemoglobin 5.7 g/dL and LDH 2,636 U/L. He was diagnosed with thrombotic thrombocytopenic purpura (TTP) and also found to be HIV positive on admission. TTP was confirmed by a low von Willebrand factor-cleaving protease level, the gold standard test for TTP, which was 10-15%. No protease-specific antibody was detected. Treatment of this patient consisted of 23 plasmapheresis procedures and trials of vincristine and dextran-70. Despite therapy, the patient remained anemic and thrombocytopenic, though his mental status and renal abnormalities improved. Highly active anti-retroviral therapy (HAART) consisting of efavirenz, 3TC, and d4T was started. Only after plasma exchanges were discontinued and HAART was instituted did the cytopenias resolve. He continued to improve following discharge, and platelet count was 206,000/microL and hemoglobin, 12.5 g/dL one month after the initiation of HAART.
