Ethylene glycol is a widely used and readily available substance. Ethylene glycol ingestion does not cause direct toxicity; however, its metabolites are highly toxic and can be fatal even in trace amounts. Poisoning is best diagnosed through inquiry, but as an impaired state of consciousness is observed in most cases, poisoning must be suspected when a significantly elevated osmolar gap or high anion gap metabolic acidosis is found in blood tests. Hemodialysis and alcohol dehydrogenase inhibitors such as ethanol and fomepizole are a part of the basic treatment, and timely diagnosis and treatment are crucial because any delays can lead to death. However, there are few reported cases in Korea, and no report on the use of fomepizole. Herein, we report a case of acute renal failure caused by ethylene glycol poisoning that was treated with fomepizole and hemodialysis and present a literature review.

PURPOSE: Extracorporeal treatment has been used increasingly to treat patients with acute ethylene glycol poisoning. We analyzed all patients with acute poisoning of ethylene glycol during a recent 10-year period to provide clinical recommendations for adequate application of continuous renal replacement therapy for these patients. METHODS: A retrospective chart review study was conducted for patients whose final diagnosis were “toxic effects of glycols or other alcohols,” between October 2006 and September 2016. The basal characteristics of patients, suspected amount of ingestion, intention of poisoning, concomitant alcohol ingestion, mental state at admission, time from exposure to admission, chief complaint, length of hospital stay, method of treatments, laboratory results including acute kidney injury and urine oxalate crystal, as well as treatment results were examined. RESULTS: A total number of 14 patients were included in this study. Nine patients (64.3%) underwent continuous renal replacement therapy; 5 patients (35.7%) underwent ethanol mono-therapy. Between the antidote therapy group and the extracorporeal treatment group, there was a significant difference in the levels of plasma bicarbonate, chloride, anion gap, pH, and base excess in arterial blood gas analysis, as well as the calculated osmolar gap. One patient expired due to multi-organ failure, while the others recovered completely. CONCLUSION: Continuous renal replacement therapy was most frequently chosen as a treatment method in patients with acute ethylene glycol poisoning. Further research regarding indication of continuous renal replacement therapy and combing therapy with other treatment will be necessary to determine the best treatment method.

BACKGROUND: Methyl alcohol poisoning has been mainly reported in community. Two cases of methyl alcohol poisoning occurred in a small-sized subcontracted factory which manufactured smartphone parts in Korea. CASE PRESENTATION: One young female patient presented with dyspnea and visual disturbance. Another young male patient presented with visual disturbance and myalgia. They treated with sodium bicarbonate infusion and hemodialysis for metabolic acidosis. In addition, he received ethyl alcohol per oral treatment. Her and his urinary methyl alcohol concentration was detected as 7.632 mg/L, 46.8 mg/L, respectively, although they were treated hemodialysis. Results of the working environment measurement showed that the concentration of methyl alcohol (1030.1–2220.5 ppm) in the air exceeded the time weighted average (200 ppm). They were diagnosed with optic neuropathy due to methyl alcohol poisoning and still have visual impairment. CONCLUSIONS: Workers who hired as dispatched employees in a small-sized subcontracted factory were exposed to high concentrations of methyl alcohol. The workplace had poor ventilation system. In addition, workers did not wear proper personal protect equipment. Working environment measurement and annual chekups for workers were not performed. They were in a blind spot to occupational safety and health. More attention is needed to protect vulnerable workers’ health.

OBJECTIVE: To investigate the relation between the expression of tPA, MMP-2, MMP-9 and AEG-1 in the human brain tissue and the ethanol concentration under the acute alcohol poison, and to analyze the role of alcohol and trauma in the mechanism of death of subarachnoid hemorrhage. METHODS: Fifteen real cases were collected in this study. The brain tissues were researched by histological examination and the concentration of ethanol in heart blood were detected. The tPA, MMP-2, MMP-9 and AEG-1 in brainstem, brain and cerebellum were observed respectively by immunohistochemistry. RESULTS: In alcohol poisoning groups with or without trauma, the acute alcohol toxicity resulted in the swelling of brain tissues. The tPA, MMP-2, MMP-9 and AEG-1 of brainstem, brain and cerebellum showed high expression in alcohol victims, and the tPA in cerebellum showed no difference. The expression of the MMP-2, MMP-9 and AEG-1 showed good relation with the ethanol concentration in blood (P < 0.05, r > 0.6). CONCLUSION The expressions of tPA, MMP-2, MMP-9 and AEG-1 are significant higher in alcohol victims, and expressions of MMP-2 and MMP-9 and AEG-1 have positive correlation with the alcohol concentration. The alcohol has acute toxicity to brain cells.

OBJECTIVETo study the influence and mechanism of acute ethanol intoxication (AEI) on rat neuronal apoptosis after severe traumatic brain injury (TBI).

METHODSNinety-six Sprague-Dawley rats were randomly divided into four groups: normal control, AEI-only, TBI-only and TBI+AEI (n equal to 24 for each). Severe TBI model was developed according to Feeney's method. Rats in TBI+AEI group were firstly subjected to AEI, and then suffered head trauma. In each group, animals were sacrificed at 6 h, 24 h, 72 h, and 168 h after TBI. The level of neuronal apoptosis and the expression of Bcl-2 protein were determined by TUNEL assay and immunohistochemical method, respectively.

RESULTSApoptotic cells mainly distributed in the cortex and white matter around the damaged area. Neuronal apoptosis significantly increased at 6 h after trauma and peaked at 72 h. Both the level of neuronal apoptosis and expression of Bcl-2 protein in TBI-only group and TBI+AEI group were higher than those in control group (P less than 0.05). Compared with TBI-only group, the two indexes were much higher in TBI+AEI group at all time points (P less than 0.05).

CONCLUSIONOur findings suggest that AEI can increase neuronal apoptosis after severe TBI.

On February 21, 2013, 6 elderly people collapsed abruptly after eating bean sprout bibimbab (boiled rice mixed with bean sprouts and seasoned with soybean sauce) at a countryside restaurant in the Chungbuk Province, Korea. Minutes after eating the meal, all of the patients lapsed into a state of stupor. Respiratory arrest developed in 2 patients; and one of two patients died of cardiac arrest. The autopsy identified methomyl and methanol in the deceased patient's gastric contents and in the remaining soybeanbean sauce seasoning. Five of the 6 patients ingested one spoonful of the soybeanbean sauce seasoning and survived, while one patient who died of cardiac arrest, ingested approximately two spoons. Symptoms of toxicity presented quickly in the subjects and progressed rapidly, including chest tightness, an unusual sensation in the pit of the stomach, dizziness, ataxia, and finally, collapse. Three patients who drank ethanol with the meal experienced only mild toxic symptoms. Our analysis of the clinical observations in these cases suggests that ingestion of methomyl pesticide and the additive toxicity of methanol may have been responsible for the intoxication.

PURPOSE: In the management of acute poisoning, the anion gap and the osmol gap are easily derived from serum laboratory findings and arterial blood gas analysis. The anion gap is known to be increased by the effects of the toxic material itself and secondary complications or by an exacerbation of an underlying illness. The osmol gap can be increased by the presence of osmotically active materials in the body, such as alcohol, glycols and mannitol. This study was proposed to investigate the significance of an increased anion gap in acutely poisoned patients and the effect of alcohol ingestion in increasing the osmol gap, which might help to understand the significance of an increased osmol gap in acutely poisoned patients. METHODS: A retrospective chart review of poisoned patients who had visited the emergency departments of the Anam and the Ansan hospitals of Korea University was used in this study. Serum laboratory findings and arterial blood gas analysis were used to measure the anion gap and the osmol gap. Patients were categorized into a non anion-gap group versus a high anion-gap group and a normal osmolgap group versus a high osmol-gap group. Frequency of toxidrome, blood pH and drinking history were included to evaluate the relations between the groups. RESULTS: Of 204 patients, 195 patients who completed the tests were included in the study. In the 99 patients with a high anion-gap, 38 (38.38%) patients showed development of toxidrome. In the 96 patients with a non anion-gap, only 15 (15.62%) patients showed toxidrome. Forty-six (80.7%) of the 57 patients with a high osmol-gap and 20 (22.2%) of the 90 patients with a normal osmol-gap had a history of drinking. CONCLUSION: In poisoned patients, the group with a higher anion gap showed a higher frequency of toxidrome. This suggests that in the management of a poisoning victim with an uncertain history, should a high anion gap be found, an intense observation and evaluation is necessary to identify the cause. An increase in the osmol gap in poisoned patients is generally considered to be from alcohol ingestion. Thus, for a patient with an increased osmol gap, measurement of the serum ethanol level should be done to exclude the effect of alcohol.
