A variety of drugs have been known to induce disulfiram-like reactions in individuals exposed to ethanol, including certain cephalosporin antibiotics with methylthiotetrazole (MTT) substituents or methylthiodioxotriazine (MTDT) rings. Among cephalosporins, cefixime is known to cause fewer disulfiram-like reactions. This case report, the first involving a pediatric patient, presents the scenario of a 14-year-old female who exhibited drowsiness, loss of consciousness, and cold extremities within an hour after ingesting 9 cefixime capsules. Upon admission, drug intoxication was considered, prompting immediate gastric lavage and toxicology tests, which revealed the presence of both cefixime and alcohol. Subsequent monitoring of vital signs, rehydration, and symptomatic treatments aimed at facilitating toxic excretion were administered during hospitalization. Following initial assessment by a clinical pharmacist, drug intoxication was deemed improbable, though an atypical disulfiram-like reaction or alcohol intoxication could not be ruled out. Further evaluation, coupled with the child\'s cefixime overdose, suggested an atypical disulfiram-like reaction. This case underscores the potential for disulfiram reactions even with cephalosporins lacking MTT substituents or MTDT rings. Notably, it is the first report of an atypical disulfiram-like reaction triggered by alcohol consumption following cefixime overdose, emphasizing the importance of caution in cefixime usage and avoidance of alcohol or alcohol-containing substances.

BACKGROUND Ethanol intoxication is very common, and several forms of alcohol intoxication can lead to emergency department visits. Excessive alcohol users, when in withdrawal, might seek replacement alcoholic beverages; one of the common sources of ethanol is hand sanitizer, which contains 45-95% alcohol. It becomes even more challenging to deal with alcohol use disorder patients when they seek these replacement products inside hospital premises, and medical clinics and hospitals have increased their use of ethanol-based hand sanitizer since the start of the COVID-19 pandemic. CASE REPORT We report the case of a 26-year-old man with alcohol dependence presenting with a fictitious illness leading to hospital admission and consumption of ethanol-based hand sanitizer in the emergency department (ED). The patient initially presented reporting severe abdominal pain that persisted despite medications. The initial laboratory tests and imaging were non-significant. The patient was later caught stealing hand sanitizer bottles, consuming them within 4-6 h. The COVID-19 pandemic has increased alcohol intoxication, especially in EDs. Hand sanitizers, including ethanol, are toxic and hazardous when misused, mostly by adolescents and young adults. Treatments include glucose determination, dextrose infusion, and thiamine perfusion. Strategies to reduce ethanol intoxication include eliminating hand sanitizers, using wall-fixed sanitizers, and using sanitizer wipes. CONCLUSIONS Patients with alcohol use disorder are known to develop alcohol-seeking behaviors. This report has highlighted that healthcare professionals should be aware that the increased availability of ethanol-based hand sanitizers, some of which contain toxic antiviral chemical agents, may be targeted by individuals with alcohol dependency.

Body embalming, a practice with deep historical roots across various cultures, forms the backbone of contemporary human body donation educational programmes. In this study, we explored current embalming practices within six South African human anatomical dissection programmes, focusing on the use and volumes of key chemicals-formalin, phenol, and alcohol-and their associated health risks and potential toxicity. We measured and compared aspects of embalming practices such as the duration of body preservation and the annual intake of bodies. Variations in embalming practices and chemical ratios across different South African universities were found. However, the consistent use of formalin, phenol and alcohol were observed across all six programmes. Formaldehyde concentrations used in South African dissection programmes were within the generally acceptable international range. Regarding arterial embalming, South African dissection programmes showed widespread adherence to international embalming practices, with one programme using a substantially lower concentration of formalin. The dual nature of formaldehyde as both an effective preservative and a recognised carcinogen was underscored in relation to human health regarding chemical toxicity. Phenol, like formaldehyde, was consistently used as it is important for the inhibition of bacterial and fungal growth. Alcohol was also consistently used, but there was much greater variation in its volume across South African institutions. Our data showed a slight positive relationship between storage duration and the volumes of formalin and phenol in human embalming fluid. South African regulators enforce stricter exposure limits than those set by the World Health Organisation and various European agencies. While South African institutions operate within internationally acceptable ranges of chemical use that both maximise preservation and minimise toxicity, we acknowledge that these data are preliminary. Further investigation is encouraged to ensure embalming practices effectively protect all those involved and support the educational goals of human anatomical dissection programmes in South Africa.

Understanding the mechanisms underlying alcohol metabolism and its regulation, including the effect of polymorphisms in alcohol-metabolizing enzymes, is crucial for research on Fetal Alcohol Spectrum Disorders. The aim of this study was to identify specific single nucleotide polymorphisms in key alcohol-metabolizing enzymes in a cohort of 71 children, including children with fetal alcohol syndrome, children prenatally exposed to ethanol but without fetal alcohol spectrum disorder, and controls. We hypothesized that certain genetic variants related to alcohol metabolism may be fixed in these populations, giving them a particular alcohol metabolism profile. In addition, the difference in certain isoforms of these enzymes determines their affinity for alcohol, which also affects the metabolism of retinoic acid, which is key to the proper development of the central nervous system. Our results showed that children prenatally exposed to ethanol without fetal alcohol spectrum disorder traits had a higher frequency of the ADH1B*3 and ADH1C*1 alleles, which are associated with increased alcohol metabolism and therefore a protective factor against circulating alcohol in the fetus after maternal drinking, compared to FAS children who had an allele with a lower affinity for alcohol. This study also revealed the presence of an ADH4 variant in the FAS population that binds weakly to the teratogen, allowing increased circulation of the toxic agent and direct induction of developmental abnormalities in the fetus. However, both groups showed dysregulation in the expression of genes related to the retinoic acid pathway, such as retinoic acid receptor and retinoid X receptor, which are involved in the development, regeneration, and maintenance of the nervous system. These findings highlight the importance of understanding the interplay between alcohol metabolism, the retinoic acid pathway and genetic factors in the development of fetal alcohol syndrome.

UNASSIGNED: Left ventricular (LV) summit arrhythmias account for up to 14% of LV arrhythmias. The ablation of LV summit arrhythmias is challenging, as testified by the fact that radiofrequency (RF) catheter ablation failure is frequent. Retrograde coronary venous ethanol infusion has been proposed as an alternative approach for the ablation of LV summit arrhythmias.
UNASSIGNED: A 47-year-old man with Lamin A/C cardiomyopathy was referred for the ablation of a pleiomorphic ventricular tachycardia (VT) storm, with dominant morphology compatible with LV summit origin. He first received a combined endo- and epicardial RF ablation with the elimination of three clinically relevant VTs. However, the dominant VT could not be ablated due to the proximity of the coronary vasculature and phrenic nerve and remained inducible. Accordingly, an urgent rescue redo procedure consisting of retrograde coronary venous ethanol ablation was performed. Based on the best pace-match and precocity, the first septal, retro-pulmonary branch and the first diagonal branch were infused with ethanol with immediate cessation of the tachycardia and non-inducibility. Anti-arrhythmic drugs were withdrawn, while guideline-directed medical therapy for heart failure was continued. No complications occurred. After 3 months, the patient remained free from any arrythmias.
UNASSIGNED: Ablation of LV summit arrythmias is challenging, especially in the context of an electrical storm or in patients with structural heart disease. In such a situation, rescue ablation with retrograde coronary venous ethanol infusion represents an attractive alternative ablation modality.

This paper intends to look into the time-varying dynamic impact of US fuel ethanol, one of the renewable energy sources, on the prices of agricultural products (specifically corn, soybeans, rice, and wheat) in China based on monthly price data from January 2000 to January 2023. To achieve this, a time-varying parameter vector autoregressive (TVP-VAR) model is employed, which takes into account structural changes in emergencies through time-varying parameters. The empirical results show that the equal-interval impulse responses of price fluctuations in agricultural commodities are primarily positive to variations in fuel ethanol prices and production. And the intensity and direction of the effects vary at distinct time lags. Additionally, the magnitude of these responses is most pronounced in the short term for all agricultural commodities except for corn, and the duration of the impulse responses at different time points is generally longer for corn prices compared to other commodities. The study also reveals that the influence of US fuel ethanol on Chinese agricultural commodity prices is not substantial on the whole. Therefore, there is a necessity to advance the growth of biofuels and provide policy support and financial subsidies for agricultural products earmarked for food production. These actions could shed insights into the progression of Chinese renewable energy and food policies, ensuring the stability of the market in the long run.

A 71-year-old male with a history of alcohol abuse and multiple suicide attempts was brought to the emergency department in an unconscious state. Initial assessment revealed profound obtundation and malnutrition. Laboratory findings demonstrated a significant anion gap metabolic acidosis with a high osmolar gap, suggestive of possible toxic alcohol ingestion. Despite negative serum alcohol levels, ethylene glycol poisoning was confirmed with a level of 226. Treatment included fluid resuscitation, bicarbonate therapy, and fomepizole administration. However, due to progressive multi-organ failure, continuous veno-venous hemodialysis was initiated. Despite interventions, the patient deteriorated rapidly, leading to a decision for hospice care, ultimately resulting in death. Ethylene glycol poisoning presents significant challenges in management, with potential complications including renal failure and multi-organ dysfunction. Fomepizole remains the cornerstone of treatment, but additional therapies such as ethanol administration were considered but ultimately deemed unnecessary due to associated risks. This case highlights the complexity and severity of ethylene glycol poisoning, emphasizing the need for early recognition and aggressive management strategies.

A 40-year-old man was incidentally found to have right-sided pelvic arteriovenous malformation (AVM) with an aneurysmal dominant outflow vein (DOV). The AVM had two main feeding arteries forming a cluster of fine vessels shunt to the DOV. As transvenous approach was impossible due to anatomical difficulty, transarterial ethanol embolization was performed under simultaneous double microballoon occlusion of the two feeding arteries in combination with protective coil embolization of the prostatic branches. Ethanol (13 mL) was intermittently injected from both microballoon catheters until the AV shunt was completely occluded. At 1-year follow-up, contrast-enhanced CT revealed shrinkage of the thrombosed DOV without any symptom. Our case demonstrated the usefulness of simultaneous double microballoon-occluded ethanol embolization for treating a localized pelvic AVM with a few feeding arteries.

In this case report, we will discuss a 74-year-old female who presented with a chief complaint of abdominal pain, bloating, anorexia, and nausea for four days which preceded after catheter ablation and anhydrous ethanol infusion vein of Marshall (VOM) one month prior. She was admitted and treated as a general patient in the general ward. After hospital admission, a pericardiocentesis was guided by B-scan ultrasonography, resulting in the extraction of 20ml of pericardial effusion, followed by catheterization for drainage. The key takeaway in this report is that anhydrous ethanol infusion VOM may not always be without risks. Hence, during the procedure, it is imperative to carefully administer the appropriate volume of anhydrous ethanol into the VOM to prevent vessel damage and associated complications.

Outbreaks of methanol poisoning have been described in the medical literature worldwide. However, the few outbreaks that have occurred in Saudi Arabia remain undocumented. This is especially noteworthy in light of the fact that Saudi Arabia is among the countries that explicitly prohibit the usage of alcoholic beverages and recreational drugs. Herein, we describe five cases of methanol poisoning in Saudi Arabia. The first three comprise patients admitted to the emergency room (ER) with signs of methanol toxicity, such as heart palpitations, vomiting, and blurred vision; otherwise, those patients were considered medically free. The remaining two cases were examined postmortem. A headspace gas chromatography-flame ionization detector was used to test blood, vitreous humor, and urine samples for methanol. Specific lethal concentrations of methanol were defined based on published case studies as 23-740 mg/dL in blood and 12-396 mg/dL in vitreous humor. In postmortem cases of our present study, samples exhibited lethal concentrations: 118 and 257 mg/dL in blood, 116.3 and 283 mg/dL in vitreous humor. In ER cases, methanol concentrations in urine samples were lower, at 7.5, 9.1, and 20.9 mg/dL; however, toxic symptoms were still observed. These case studies indicate that it is necessary to raise community awareness about the risk of methanol poisoning in order to minimize future poisoning epidemics.
