/EXPL THER/ Ethanol lock therapy (ELT) has emerged as an effective method for the prevention and treatment of central line-associated bloodstream infections (CLABSIs), but the safety of ELT in infants has not been established. The objective of this study was to determine blood alcohol concentration (BAC) and evidence of hepatic injury in infants after infusing a small one-time dose of ethanol, equivalent to the volume that would be flushed through the central venous catheter (CVC) after ELT is completed. This was a prospective pilot study in infants weighing

/The objective of the study was/ to evaluate the efficacy, safety, pain perception and health-related quality of life (QoL) of percutaneous ethanol injection treatment (PEIT) as an alternative to thyroid surgery in symptomatic thyroid cysts. Thirty consecutive patients (46 +/- 10 years; 82% women) with symptomatic benign thyroid cysts relapsed after drainage were included. In all cases, cytology prior to treatment, maximum cyst diameter and volume were determined. PEIT was conducted using the established procedure, and the volume of fluid removed and pain perceived by the patient were assessed. In each procedure, the volume of alcohol instilled was <2 mL. After follow-up, final cyst diameter and volume were determined and the persistence of symptoms and QoL were assessed by a questionnaire (SF-36). Mean symptom duration was 10 +/- 20 months. A single session of PEIT was required to complete the procedure in 45% of patients, two in 31% and three in 13%. Mean initial maximum cyst diameter was 3.5 +/- 1.0 cm and mean extracted liquid volume 61 +/- 36 mL. During PEIT, 39% of patients experienced virtually no pain, 43% mild pain and 17% moderate pain. No complications of PEIT were observed. After 12.1 +/- 1.4 months of follow-up, cysts were reduced more than 70% in volume in 86.3% of patients, more than 80% in 61.9% and more than 90% in 42%. On the health-related QoL SF-36 questionnaire, patient scores 6 months post-PEIT did not differ significantly from those of the healthy Spanish population. With respect to cosmetic complaints or local symptoms of compression, PEIT-treated patients presented an initial score of 22 +/- 8 and 13 +/- 5 after treatment (p < 0.05). In our experience, percutaneous ethanol injection has proved to be an effective, safe and well-tolerated first-line treatment of symptomatic thyroid cysts.

Because of the increased risk of surgery, thyroid nodules causing compression signs and/or hyperthyroidism are concerning during pregnancy. Six patients with nontoxic cystic, four with nontoxic solid, and three with overt hyperthyroidism caused by toxic nodules were treated with percutaneous ethanol injection therapy (PEI). An average of 0.68 mL ethanol per 1 mL nodule volume was administered. Mean number of PEI treatments for patients was 2.9. Success was defined as the shrinkage of the nodule by more than 50% of the pretreatment volume (V0) and the normalization of TSH and FT4 levels. The average V0 was 15.3 mL. Short-term success was measured prior to labor, whereas long-term success was determined during the final follow-up (an average of 6.8 years). The pressure symptoms decreased in all but one patient after PEI and did not worsen until delivery. The PEI was successful in 11 (85%) and 7 (54%) patients at short-term and long-term follow-up, respectively. Three patients underwent repeat PEI which was successful in 2 patients. PEI is a safe tool and seems to have good short-term results in treating selected symptomatic pregnant patients. Long-term success may require repeat PEI.

Methanol poisoning outbreaks are a global public health issue, with delayed treatment causing poor outcomes. Out-of-hospital ethanol administration may improve outcome, but the difficulty of conducting research in outbreaks has meant that its effects have never been assessed. We study the effect of out-of-hospital ethanol in patients treated during a methanol outbreak in the Czech Republic between 2012 and 2014. This was an observational case-series study of 100 hospitalized patients with confirmed methanol poisoning. Out-of-hospital ethanol as a "first aid antidote" was administered by paramedic or medical staff before the confirmation of diagnosis to 30 patients; 70 patients did not receive out-of-hospital ethanol from the staff (12 patients self-administered ethanol shortly before presentation). The state of consciousness at first contact with paramedic or medical staff, delay to admission, and serum methanol concentration were similar among groups. The median serum ethanol level on admission in the patients with out-of-hospital administration by paramedic or medical staff was 84.3 mg/dL (interquartile range 32.7 to 129.5 mg/dL). No patients with positive serum ethanol level on admission died compared with 21 with negative serum ethanol level (0% versus 36.2%). Patients receiving out-of-hospital ethanol survived without visual and central nervous system sequelae more often than those not receiving it (90.5% versus 19.0%). A positive association was present between out-of-hospital ethanol administration by paramedic or medical staff, serum ethanol concentration on admission, and both total survival and survival without sequelae of poisoning. We found a positive association between out-of-hospital ethanol administration and improved clinical outcome. During mass methanol outbreaks, conscious adults with suspected poisoning should be considered for administration of out-of-hospital ethanol to reduce morbidity and mortality.

Although there is a dose response relationship between alcohol consumption and liver damage, less than one-third of alcoholics develop alcoholic liver disease (ALD). This individual susceptibility to the development of alcoholic liver disease may be explained by genetic and environmental factors. Of the genetic factors, female sex is clearly a significant risk factor, human leukocyte antigen status is probably important but further studies are needed, abnormalities in alcohol metabolism have not been shown to be of primary pathogenic importance and the plethora of immunological disturbances reported appear to be mere epiphenomena. Of the environmental factors, no consistent evidence attests to the significance of hepatitis B viral infection in the susceptibility to developing alcoholic liver disease.

Two patients developed hepatic infarction after undergoing percutaneous ethanol injection therapy (PEIT) for hepatocellular carcinoma (HCC). In both cases, liver function parameters deteriorated immediately after the ethanol injection, and enhanced computed tomography images showed a wedge-shaped avascular low-density area due to hepatic infarction. In one patient, PEIT was performed for a nodule treated with transcatheter arterial infusion (TAI) using a suspension of styrene maleic acid neocarzinostatin (SMANCS) 4 weeks before. In the other patient, TAI with SMANCS had been carried out 14 months previously for a different nodule in the same segment where the nodule treated with PEIT was located. When PEIT is used for patients with HCC who have previously undergone TAI, especially with SMANCS, PEIT may induce hepatic infarction.

Since 1990, percutaneous ethanol injection therapy (PEIT) has been clinically applied as a treatment for autonomous functioning nodules of the thyroid as well as for cystic lesions. Some additional indications are currently under consideration, e.g. inoperable advanced cancer of the thyroid. Since its inception, PEIT has generally been regarded as an effective, low-risk, inexpensive procedure which can be performed on an ambulatory basis. /The authors/ report the first case of severe ethyl toxic necrosis of the larynx combined with necrotic dermatitis in a patient treated with PEIT by a radiologist. The patient was admitted to hospital, where the necrosis and dermatitis were treated conservatively. A cyst which developed in the right false vocal fold was removed by microsurgery 10 months later. Voice was restored almost to normal but a significant reduction in nodular volume was not seen, probably due to the inexperience of the operator. PEIT for functional thyroid gland autonomy is an inexpensive method of treating hyperthyroidism with focal autonomy on an ambulatory basis if surgical intervention and radioiodine therapy are not feasible either for medical reasons or because of refusal by the patient. Severe complications must be taken into consideration and discussed with the patient. To avoid complications, substantial experience and a precise ultrasound-guided injection are required. In the case of complications the opinion of a specialist should be sought at an early stage.

Alcohol produces injury to cells by dehydration and precipitation of the cytoplasm or protoplasm. This accounts for its bacteriocidal and antifungal action. When alcohol is injected in close proximity to nerve tissues, it produces neuritis and nerve degeneration (neurolysis). Ninety to 98% of ethanol that enters the body is completely oxidized. Ethanol is also used as a cosolvent to dissolve many insoluble drugs and to serve as a mild sedative in some medicinal formulations. Ethanol also binds to GABA, glycine, NMDA receptors and modulates their effects. Ethanol is also metabolised by the hepatic enzyme alcohol dehydrogenase.

Absorption
Rapidly absorbed.
After oral administration, ethanol is absorbed rapidly into the bloodstream from the stomach and small intestines and distributes into total body water (0.5-0.7 L/kg). Peak blood levels occur about 30 minutes after ingestion of ethanol when the stomach is empty. Because absorption occurs more rapidly from the small intestine than from the stomach, delays in gastric emptying (owing, e.g., to the presence of food) slow ethanol absorption. ... After oral consumption of alcohol, first-pass metabolism by gastric and liver alcohol dehydrogenase enzymes leads to lower blood alcohol levels than would be obtained if the same dose were administered intravenously.

The distribution of alcohol between alveolar air and blood depends on its speed of diffusion, and its vapor pressure at the prevailing temp and concentration of alcohol in the lung capillaries. Empirical determinations have yielded rather different values for this distribution ratio, but a commonly accepted value is 1:2100.

Venous blood (orbital sinus) and brain ethanol levels were measured in long sleep and short sleep mice within the first 30 min following ethanol administration (2.5 to 6.0 g/kg). Ethanol was administered ip or intragastrically. For both lines of mice and for every dose, brain ethanol concentrations were significantly greater (as much as 100 mg/dL) than blood ethanol levels for the first 6 min, and peak blood and brain ethanol levels were reached 4 to 6 min after dosing. Approx 6 to 10 min (depending on dose and line of mouse) was required for blood and brain concn to reach equilibrium. At the time of loss of the righting response brain ethanol levels were significantly higher than blood ethanol levels. These results indicate that within the first 6 min after administration of ethanol, blood ethanol level is not suitable for the assessment of brain ethanol content.

Hepatic. Metabolized by cytochrome P450 enzyme CYP2E1.
Ethanol metabolism in hepatocytes causes the generation of reactive oxygen species, endoplasmic reticulum stress and alterations in mitochondrial energy and REDOX metabolism. In ethanol-exposed liver disease, autophagy not only acts as a cleanser to remove damaged organelles and cytosolic components, but also selectively clears specific targets such as lipid droplets and damaged mitochondria. Moreover, ethanol appears to play a role in protecting hepatocytes from apoptosis at certain concentrations. This article describes the evidence, function and potential mechanism of autophagy in ethanol-exposed liver disease and the controversy surrounding the effects of ethanol on autophagy.

There have been allegations in the courtroom that elevated serum lactic acid in trauma victims can yield a falsely elevated serum ethanol assay. Most hospitals utilize an indirect method of ethanol measurement where a serum sample is added to a mix of alcohol dehydrogenase and oxidized nicotinamide adenine dinucleotide (NAD+). This allows any ethanol in the patient's serum to be metabolized to acetaldehyde, and in the process results in the reduction of NAD+ to NADH. NADH is then measured using spectrophotometry. The courtroom allegation stems from the concept that oxidation of lactate to pyruvate by lactate dehydrogenase (LDH) results in the same molar-for-molar reduction of NAD+ to NADH, and could therefore theoretically cause patients with elevated lactate and LDH to have a falsely elevated ethanol concentration. Patients with elevated lactic acid and LDH concentrations who presented to a university hospital from 20 April 2015 to 13 December 2015 were identified to provide possible test specimens. If a sufficient amount of serum was available, the sample was used to re-run the lactate and LDH concentration simultaneously with an enzymatic ethanol assay. Any samples that had elevated lactic acid and LDH concentrations on this retesting, and also yielded a positive ethanol concentration, were sent for confirmatory gas chromatography testing of ethanol concentrations. A control group of 20 samples with normal lactate and LDH were included. A total of 37 samples were included in the final analysis. Only 4 patients had an elevated enzymatic ethanol concentration, and all 4 also had a measurable GC ethanol concentration. The lactate in this dataset ranged from 2.4 to 24.2 mmol/L, with a mean of 6.53 mmol/L (normal value 0.5-2.2). The LDH ranged from 242 to 8838 U/L with a mean of 1695 U/L (normal value 122-225 U/L). Twenty control samples were run on patients with normal lactate and LDH, none of which yielded a positive enzymatic ethanol result. This data does not support the contention that an elevated LDH and lactate can yield a false positive serum ethanol result as run by enzymatic ethanol assay in live patients presenting to the emergency department.

Ethanol is metabolized largely by sequential hepatic oxidation, first to acetaldehyde by alcohol dehydrogenase (ADE) and then to acetic acid by aldehyde dehydrogenase (ALDH). Each metabolic step requires NAD+; thus oxidation of 1 mol ethanol (46 g) to 1 mol acetic acid requires 2 mol NAD+ in the liver; indeed, NAD+ availability limits ethanol metabolism to about 8 gr or 10 mL (approximately 170 mmol) per hour in a 70-kg adult, or approximately 120 mg/kg per hour. Thus hepatic ethanol metabolism functionally saturates at relatively low blood levels compared with the high blood ethano levels (BELs) achieved, and ethanol metabolism is a zero-order process (constant amount per unit time). Small amounts of ethanol are excreted in urine, sweat, and breath, but metabolism to acetate accounts to 90-98% of ingested ethanol, mostly owing to hepatic metabolism by ADH and ADLH.

Metabolism of ethanol, propanol, isopropanol, butanol, isobutanol, sec-butanol, and tert-butanol was studied after oral administration in rabbits. Blood pH was on the acid side with propanol, butanol, and isobutanol, and on the alkaline side with isopropanol and sec-butanol, but no change was observed with ethanol and tert-butanol. Butanol and isobutanol had the lowest rate of urinary excretion. Acetaldehyde and acetic acid were detected as the urinary metabolites of ethanol and propanol, whereas isobutyraldehyde and isovaleric acid were the metabolites of isobutanol.

Ethanol affects the brains neurons in several ways. It alters their membranes as well as their ion channels, enzymes, and receptors. Alcohol also binds directly to the receptors for acetylcholine, serotonin, GABA, and the NMDA receptors for glutamate. The sedative effects of ethanol are mediated through binding to GABA receptors and glycine receptors (alpha 1 and alpha 2 subunits). It also inhibits NMDA receptor functioning. In its role as an anti-infective, ethanol acts as an osmolyte or dehydrating agent that disrupts the osmotic balance across cell membranes.
... Ethanol is known to affect a large number of membrane proteins that participate in signaling pathways such as neurotransmitter receptors, enzymes, and ion channels, and there is extensive evidence that ethanol interacts with a variety of neurotransmitters. The major actions of ethanol involve enhancing the inhibitory effects of gamma-aminobutyric acid (GABA) at GABAa receptors and blockade of the N-methyl-D-aspartate (NMDA) subtype of glutamate, an excitatory amine acid (EAA) receptor. Animal studies indicate that the acute effects of ethanol result from competitive inhibition of glycine binding to NMDA receptor and disruption of glutamatergic neurotransmission by inhibiting the response of the NMDA receptor. Persistent glycine antagonism and attenuation of glutamatergic neurotransmission by chronic ethanol exposure results in tolerance to ethanol by enhancing EAA neurotransmission and NMDA receptor upregulation. The latter appears to involve selective increases in NMDA R2B subunit concentrations and other molecular changes in specific brain loci. The abrupt withdrawal of ethanol thus produces a hyperexcitable state that leads to the ethanol withdrawal syndrome and excitotoxic neuronal death. GABA-mediated inhibition, which normally acts to limit excitation, is eliminated during ethanol withdrawal syndrome and further intensifies this excitation. In addition, NMDA receptors function to inhibit the release of dopamine in the nucleus accumbens and mesolimbic structures, which modulate the reinforcing action of addictive xenobiotics such as ethanol. By inhibiting NMDA receptor activity, ethanol could increase dopamine release from the nucleus accumbens and ventral tegmental area and could thus create dependence. Chronic ethanol administration also results in tolerance, dependence, and an ethanol withdrawal syndrome, mediated, in part, by desensitization and or downregulation of GABAa receptors.

The development of alcoholic ketoacidosis (AKA) requires that a combination of physical and physiologic events occur. The normal response to starvation and depletion of hepatic glycogen stores is for amino acids to be converted to pyruvate. Pyruvate can serve as a substrate for gluconeogenesis, be converted to acetyl-CoA, which can enter the Krebs cycle or can be utilized in various biosynthetic pathways (eg, fatty acid, ketone bodies, cholesterol, and acetylcholine) ... Ethanol metabolism generates NADH, resulting in an excess of reducing potential. This high redox state favors the conversion of pyruvate to lactate, diverting pyruvate from being a substrate for gluconeogenesis. To compensate for the lack of normal metabolic substrates, the body mobilizes fat from adipose tissue and increased fatty acid metabolism as an alternative source of energy. This response is mediated by a decrease in insulin and an increased secretion of glucagon, catecholamines, growth hormone, and cortisol. Fatty acid metabolism results in the formation of acetyl-CoA and it combines with the excess acetate that is generated from ethanol metabolism to form acetoacetate. Most of the acetoacetate is reduced to beta-hydroxybutyrate due to the excess reducing potential or high redox state of the cell. Volume depletion interferes with the renal elimination of acetoacetate and beta-hydroxybutyrate, and contributes to the acidosis. An elevated lactate concentration may result from shunting from pyruvate or from hypoperfusion or infection that may coexist with the underlying ketoacidosis.

Adenosine may mediate many of the acute and chronic motor effects of ethanol on the brain. Ethanol, probably through its metabolite, acetate, prevents adenosine uptake, raising synaptic adenosine concentrations. Excessive stimulation of several adenosine receptors in the cerebellum may explain much of the motor impairment from low ethanol concentrations. In fact, animals made tolerant to ethanol develop cross-tolerance to adenosine agonists. In mice, adenosine receptor agonists increase ethanol-induced incoordination while adenosine antagonists decrease this intoxicating response.

Chronic ethanol (alcohol) administration has been associated with alterations in the binding and function of the gamma-aminobutyric acid (GABAA) receptor. To evaluate the mechanism underlying these changes, /the authors/ measured the steady state levels of the mRNAs for the alpha 1, alpha 2, alpha 3, alpha 5, and alpha 6 subunits of the GABAA receptor after chronic ethanol administration to rats and ethanol withdrawal for 24 hr. The results indicated that chronic ethanol administration resulted in a 61% decline in the level of the GABAA receptor alpha 1 subunit mRNAs [3.8 and 4.3 kilobases (kb)] in the cerebral cortex in rats. The levels of the alpha 2 subunit mRNAs (6 and 3 kb) and the alpha 5 subunit mRNA (2.8 kb) were also reduced, by 61, 45, and 51%, respectively, whereas there was no change in the level of the alpha 3 subunit mRNA (3 kb). Furthermore, the ethanol-induced decrease in receptor mRNA levels persisted for 24 hr, after withdrawal of ethanol and returned to control values at 36 hr of withdrawal. alpha 1 mRNA levels in cerebellum also decreased by 28%. The level of the alpha 6 subunit mRNA, which selectively encodes Ro15-4513 binding sites, was found to be increased by approximately 76% in the cerebellum. Also, the photoaffinity labeling studies using [3H]Ro15-4513 indicated an increase in the levels of various protein components of the GABAA receptor, in the cerebellum and the cerebral cortex (e.g., 50- and 55-kDa proteins in the cerebellum and 41- and 50-kDa proteins in the cortex), after chronic ethanol treatment. The increase in alpha 6 mRNA in the cerebellum might be related to the increased labeling of the 55-kDa (approximately 56-kDa) protein and partially responsible for the increased binding ... . Because the alpha 6 subunit is not expressed in cortex, involvement of an as yet unknown subunit in this region cannot be ruled out. The effect of chronic ethanol treatment appears to be specific for GABAA receptor subunit mRNAs, because the same treatment did not alter the levels of glyceraldehyde-3-dehydrogenase mRNA or poly(A)+ RNA. In summary, these data indicate that chronic ethanol treatment results in an alteration in the regulation of expression of GABAA receptor subunit-encoding mRNAs, which could be due to alterations in transcription or mRNA stability.
