This condition may occasionally be fatal. It was formerly called delirium tremens. (From Adams et al., Principles of Neurology, 6th ed, p1175)
Drinking an excessive amount of ALCOHOLIC BEVERAGES in a short period of time.

Alcohol-histamine interactions. (1/186)

Alcohol and histamine metabolic pathways in the body have the common enzymes aldehyde dehydrogenase and aldehyde oxidase. The metabolite of ethanol, acetaldehyde, can effectively compete with the metabolites of histamine, methylimidazole acetaldehyde, and imidazole acetaldehyde. At the periphery, alcohol and acetaldehyde liberate histamine from its store in mast cells and depress histamine elimination by inhibiting diamine oxidase, resulting in elevated histamine levels in tissues. Histamine mediates alcohol-induced gastric and intestinal damage and bronchial asthma as well as flushing in Orientals. On the other hand, alcohol provokes food-induced histaminosis and histamine intolerance, which is an epidemiological problem. There are many controversial reports concerning the effect of H2 receptor antagonists on ethanol metabolism and the activity of alcohol dehydrogenase in the stomach. In addition, alcohol affects histamine levels in the brain by modulating histamine synthesis, release, and turnover. Histamine receptor antagonists can affect ethanol metabolism and change the sensitivity of animals to the hypnotic effects of alcohol. In contrast to other neurotransmitters, the involvement of the brain histamine system in the mechanisms of the central actions of alcohol and in the pathogenesis of alcoholism is poorly studied and understood.  (+info)

Effects of naltrexone and fluoxetine on alcohol self-administration and reinstatement of alcohol seeking induced by priming injections of alcohol and exposure to stress. (2/186)

We have recently shown that priming injections of alcohol and footshock stress reinstate alcohol seeking in drug-free rats. Here we tested whether naltrexone and fluoxetine, two drugs used in the treatment of alcohol dependence, would affect reinstatement of alcohol seeking induced by these events. We also determined the effects of these drugs on alcohol self-administration during the maintenance phase. Rats were trained to press a lever for a 12% w/v alcohol solution. After stable drug-taking behavior was obtained, lever pressing for alcohol was extinguished. Reinstatement of drug seeking was then determined after priming injections of alcohol (0.24-0.96 g/kg) or exposure to intermittent footshock (5 and 15 min). Rats were pretreated with naltrexone (0.2-0.4 mg/kg) or fluoxetine (2.5-5 mg/kg) during maintenance or during tests for reinstatement. Both naltrexone and fluoxetine decreased lever presses for alcohol during the maintenance phase. Naltrexone blocked alcohol-induced, but not stress-induced reinstatement. In contrast, fluoxetine blocked stress-induced reinstatement, while its effect on alcohol-induced reinstatement was less consistent. The implications of these data to the understanding of relapse to alcohol are discussed.  (+info)

Effects of Hypericum perforatum extraction on alcohol intake in Marchigian Sardinian alcohol-preferring rats. (3/186)

The present study investigated the effect of acute intragastric (i.g.) administration of dry Hypericum perforatum extract (HPE), containing 0.3% hypericin, on ethanol intake in genetically selected Marchigian Sardinian alcohol-preferring (msP) rats. The i.g. administration of HPE, 125 or 250 mg/kg, induced a 30-40% reduction in ethanol intake in rats offered 10% (v/v) ethanol for 2 h/day. The effect of these doses was selective, since they modified neither food intake nor food-associated drinking; neither did the same doses modify the rat's gross behaviour in the open-field test. A dose of 500 mg/kg frequently induced immobility and a general suppression of ingestive behaviour. In rats offered 10% ethanol for 12 h/day, ethanol intake following treatment with 250 mg/kg HPE was significantly lower than that of controls for up to 10 h. The effect on ethanol intake was not related to the antidepressant-like effect of HPE revealed in the forced swimming test. In this regard, the effect on ethanol intake was observed after a single administration of 125 mg/kg, whereas the antidepressant effect was observed only after repeated treatment with doses higher than 125 mg/kg HPE. The i.g. administration of HPE, 250 mg/kg, did not affect blood-alcohol levels following i.g. treatment with 0.7 g/kg ethanol, the amount usually ingested in a single drinking episode; thus, the effect is not related to changes in the pharmacokinetics of ethanol. The present study shows that HPE markedly reduces ethanol intake in msP rats, without significantly modifying food intake.  (+info)

Attenuation of alcohol intake by extract of Hypericum perforatum (St. John's Wort) in two different strains of alcohol-preferring rats. (4/186)

Extract of the common plant Hypericum perforatum L. (St John's Wort, SJW) has been used successfully for the treatment of mild to moderate depression since ancient times and has recently been studied clinically. Depression and alcoholism have some neurochemical similarities, such as low brain serotonin activities. Thus, we hypothesized that SJW extract, which contains 0.22% hypericin and 4.05% hyperforin, also may be effective in suppressing alcohol intake. To test this hypothesis, the effects of SJW extract on voluntary alcohol intake were studied in two different genetic animal models of human alcoholism: fawn-hooded (FH) and high-alcohol drinking (HAD) rats. FH and HAD rats received a single oral administration (5 ml/kg) of either vehicle or one of the five doses (100, 200, 400, 600, and 800 mg/kg) of SJW extract. The oral administration of SJW extract significantly (P < 0.0001) reduced alcohol intake in both FH and HAD rats. In a third study, FH rats did not develop tolerance to the suppressant effects of SJW on alcohol intake and preference following oral administration of (400 mg/kg) of the extract for 15 consecutive days. These promising findings suggest that SJW extract should be evaluated clinically as a potential therapeutic agent in the treatment of alcoholism.  (+info)

United Kingdom Multicentre Acamprosate Study (UKMAS): a 6-month prospective study of acamprosate versus placebo in preventing relapse after withdrawal from alcohol. (5/186)

A 6-month randomized controlled study of acamprosate versus placebo in preventing relapse following withdrawal from alcohol was undertaken in 20 centres throughout the UK. Patients diagnosed as alcohol-dependent and detoxified within the preceding 5 weeks were randomly assigned to treatment with either acamprosate (A) 666 mg three times/day or identical placebo (P). A total of 664 patients were screened; 581 were entered into the treatment phase. One-third were episodic drinkers, 84% were male, 44% were unmarried and 48% were unemployed. Medication was first taken on average 24 days after the start of detoxification; 32% of patients had already relapsed by this time. The 6-month study period was completed by 35% of patients; adverse events led to withdrawal of a further 14% (A) and 9% (P) respectively. Compliance was poor in that, by the end of the second week, only 57% of patients were judged to be taking at least 90% of their tablets. The mean total of abstinent days achieved was 77 (A) and 81 (P). Complete abstinence for 6 months was achieved by 12% (A) and 11% (P); drinking remained within controlled limits in a further 3% (A) and 6% (P). An effect of acamprosate on consumption was not seen when subgroups, including those defined by the Lesch typology, were analysed separately. However, the mean percentage reduction in craving for alcohol measured on a visual analogue scale was greater in the acamprosate, than placebo, patients at week 2 and week 4 (P<0.001) and the mean decrease in the Hamilton Anxiety score at the 4th week was greater in the acamprosate than placebo patients (P = 0.017). In comparison with other published trials of acamprosate, patients started study medication after a longer time following detoxification, had more often recommenced drinking before medication was started and had a higher drop-out rate, and this might have contributed to the lack of a treatment effect in this study.  (+info)

Acamprosate and relapse prevention in the treatment of alcohol dependence: a placebo-controlled study. (6/186)

The objective of this study was to compare acamprosate with placebo in the treatment of alcohol-dependent patients during a 6-month post-detoxification treatment and a 3-month medication-free follow-up. Patients (n = 330) were detoxified and randomized to treatment with acamprosate (1998 mg/day) or placebo within an out-patient programme including medical counselling, psychotherapy and self-help groups. The main outcome criterion was drinking behaviour as assessed by: abstinence/relapse ratio, cumulative abstinence duration (CAD) and the period of continued abstinence. Anxiety, depression and craving were also monitored. Intention to treat (ITT) statistical principles were followed. Twenty-five per cent of patients dropped out over the first 6 months. At the end of the treatment period, the abstinence rate was 57.9% for acamprosate and 45.2% for placebo (P = 0.03). The CAD was 110+/-77 days for acamprosate and 89+/-77 days for placebo (P = 0.016). Patients on acamprosate had a higher continuous abstinence rate and experienced less severe relapses. No differential effect was noted for anxiety, depression or craving. Treatment remained positive, but not significant, 3 months after termination of study medication. No significant difference in adverse events was noted between treatment groups. Acamprosate treatment over 180 days was consistently more effective than placebo to maintain abstinence and to diminish relapse severity.  (+info)

Blockage of drug resistance in vitro by disulfiram, a drug used to treat alcoholism. (7/186)

BACKGROUND: P-glycoprotein (P-gp) pumps a wide range of cytotoxic drugs out of cells. Inhibiting maturation of P-gp would be a novel method for circumventing P-gp-mediated multidrug resistance, which complicates cancer chemotherapy and treatment of patients infected with human immunodeficiency virus. We examined the effect of disulfiram (Antabuse(TM)) on the maturation and activity of P-gp. METHODS: Embryonic kidney cells were transfected with a complementary DNA for the P-pg gene, and the effects of disulfiram on the sensitivity of the transfected cells to cytotoxic agents were determined. Enzyme assays were used to determine the effects of disulfiram on the verapamil-stimulated adenosine triphosphatase (ATPase) activity of P-gp. Disulfiram modifies cysteine residues, and mutant forms of P-gp that lack individual cysteines were used to determine whether particular cysteine residues mediate disulfiram's effects on P-gp activity. Maturation of recombinant P-gp was followed on immunoblots. RESULTS: Disulfiram increased the sensitivity of P-gp-transfected cells to vinblastine and colchicine and inhibited P-gp's verapamil-stimulated ATPase activity. Half-maximal inhibition of ATPase activity occurred at 13.5 microM disulfiram. Disulfiram (at 100 microM) inhibited a P-gp mutant by 43% (95% confidence interval [CI] = 37%-48%) when cysteine was present at position 431 only and by 72% (95% CI = 66%-77%) when cysteine was present at position 1074 only. Treatment of P-gp-transfected cells with 50 nM disulfiram blocked maturation of recombinant P-gp. CONCLUSIONS: Disulfiram can potentially reduce P-gp-mediated drug resistance by inhibiting P-gp activity (possibly via cysteine modification) and/or by blocking its maturation. These results suggest that disulfiram has the potential to increase the efficacy of drug therapies for cancer and acquired immunodeficiency syndrome.  (+info)

Identifying and treating patients with alcohol-related problems. (8/186)

Problem drinking is a serious health issue, but often patients whose alcohol consumption places them at risk are not diagnosed by physicians. Case finding is an essential component of "best practice." In many cases if given the appropriate advice, counselling and behavioural interventions, problem drinkers can be helped to reduce their use of alcohol and improve functioning in other areas of their lives. Some patients may benefit from more comprehensive therapy including the prescription of disulfiram, calcium carbimide or naltrexone. For those with serious problems with alcohol, referral to specialized addiction treatment programs and other community resource centres may also be appropriate.  (+info)

Alcohol deterrents, also known as alcohol deterrent devices or ignition interlock devices, are breathalyzer devices that are installed in vehicles to prevent a driver from starting the vehicle if their blood alcohol concentration (BAC) is above a certain limit. These devices are often used as a condition of license reinstatement for individuals who have been convicted of drunk driving or other alcohol-related offenses.

The driver must blow into the device, and if their BAC is above the programmed limit, the vehicle will not start. Some devices also require periodic rolling retests while the vehicle is in motion to ensure that the driver remains sober throughout the trip. The use of alcohol deterrents has been shown to reduce recidivism rates among drunk drivers and improve overall road safety.

'Alcohol drinking' refers to the consumption of alcoholic beverages, which contain ethanol (ethyl alcohol) as the active ingredient. Ethanol is a central nervous system depressant that can cause euphoria, disinhibition, and sedation when consumed in small to moderate amounts. However, excessive drinking can lead to alcohol intoxication, with symptoms ranging from slurred speech and impaired coordination to coma and death.

Alcohol is metabolized in the liver by enzymes such as alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). The breakdown of ethanol produces acetaldehyde, a toxic compound that can cause damage to various organs in the body. Chronic alcohol drinking can lead to a range of health problems, including liver disease, pancreatitis, cardiovascular disease, neurological disorders, and increased risk of cancer.

Moderate drinking is generally defined as up to one drink per day for women and up to two drinks per day for men, where a standard drink contains about 14 grams (0.6 ounces) of pure alcohol. However, it's important to note that there are no safe levels of alcohol consumption, and any level of drinking carries some risk to health.

Insect repellents are substances that are applied to the skin, clothing, or other surfaces to deter insects from landing or crawling on that surface. They work by masking the scents that attract insects or by repelling them with unpleasant odors. Insect repellents can be chemical-based, such as those containing DEET (N,N-diethyl-m-toluamide), picaridin, or IR3535, or they can be natural, such as those containing oil of lemon eucalyptus or citronella. These substances work by interfering with the insect's ability to detect human scent, making it less likely that they will come into contact with the person using the repellent. Insect repellents are an important tool in preventing insect-borne diseases such as Lyme disease, West Nile virus, and Zika virus.

In chemistry, an alcohol is a broad term that refers to any organic compound characterized by the presence of a hydroxyl (-OH) functional group attached to a carbon atom. This means that alcohols are essentially hydrocarbons with a hydroxyl group. The simplest alcohol is methanol (CH3OH), and ethanol (C2H5OH), also known as ethyl alcohol, is the type of alcohol found in alcoholic beverages.

In the context of medical definitions, alcohol primarily refers to ethanol, which has significant effects on the human body when consumed. Ethanol can act as a central nervous system depressant, leading to various physiological and psychological changes depending on the dose and frequency of consumption. Excessive or prolonged use of ethanol can result in various health issues, including addiction, liver disease, neurological damage, and increased risk of injuries due to impaired judgment and motor skills.

It is important to note that there are other types of alcohols (e.g., methanol, isopropyl alcohol) with different chemical structures and properties, but they are not typically consumed by humans and can be toxic or even lethal in high concentrations.

Oviposition is a medical/biological term that refers to the process of laying or depositing eggs by female organisms, including birds, reptiles, insects, and fish. In humans and other mammals, the term is not applicable since they give birth to live young rather than laying eggs.

"Sensilla" is a term used in anatomy and physiology, particularly in insects and other arthropods. It refers to the sensory structures or receptors found on the external surface of these organisms, which are responsible for detecting various environmental stimuli such as touch, taste, smell, temperature, and humidity.

These sensilla are often small, hair-like or peg-like projections that contain one or more sensory cells or neurons. They can be found on different parts of the insect body, including the antennae, legs, mouthparts, and cerci. The structure and function of sensilla vary depending on their location and the type of stimuli they detect.

Overall, sensilla play a crucial role in helping insects and other arthropods navigate and interact with their environment, allowing them to respond to various stimuli and make appropriate behavioral decisions.

Feeding behavior refers to the various actions and mechanisms involved in the intake of food and nutrition for the purpose of sustaining life, growth, and health. This complex process encompasses a coordinated series of activities, including:

1. Food selection: The identification, pursuit, and acquisition of appropriate food sources based on sensory cues (smell, taste, appearance) and individual preferences.
2. Preparation: The manipulation and processing of food to make it suitable for consumption, such as chewing, grinding, or chopping.
3. Ingestion: The act of transferring food from the oral cavity into the digestive system through swallowing.
4. Digestion: The mechanical and chemical breakdown of food within the gastrointestinal tract to facilitate nutrient absorption and eliminate waste products.
5. Assimilation: The uptake and utilization of absorbed nutrients by cells and tissues for energy production, growth, repair, and maintenance.
6. Elimination: The removal of undigested material and waste products from the body through defecation.

Feeding behavior is regulated by a complex interplay between neural, hormonal, and psychological factors that help maintain energy balance and ensure adequate nutrient intake. Disruptions in feeding behavior can lead to various medical conditions, such as malnutrition, obesity, eating disorders, and gastrointestinal motility disorders.

In the context of mental health and psychology, "predatory behavior" is not a term that is commonly used as a medical diagnosis or condition. However, it generally refers to aggressive or exploitative behavior towards others with the intention of taking advantage of them for personal gain or pleasure. This could include various types of harmful behaviors such as sexual harassment, assault, stalking, bullying, or financial exploitation.

In some cases, predatory behavior may be associated with certain mental health conditions, such as antisocial personality disorder or psychopathy, which are characterized by a disregard for the rights and feelings of others. However, it's important to note that not all individuals who engage in predatory behavior have a mental health condition, and many people who do may not necessarily exhibit these behaviors.

If you or someone else is experiencing harm or exploitation, it's important to seek help from a trusted authority figure, such as a healthcare provider, law enforcement officer, or social worker.

Euphorbia is a genus of plants that belongs to the spurge family (Euphorbiaceae). It contains around 2,000 species of shrubs, trees, and herbs that are found worldwide, particularly in tropical and subtropical regions. Many euphorbias are known for their milky sap, which can be toxic or irritating to the skin and mucous membranes. Some species of euphorbia are cultivated as ornamental plants due to their attractive flowers and foliage, while others have medicinal or industrial uses. However, it's important to note that some euphorbias can be invasive and harmful to local ecosystems, so care should be taken when handling or growing them.

A larva is a distinct stage in the life cycle of various insects, mites, and other arthropods during which they undergo significant metamorphosis before becoming adults. In a medical context, larvae are known for their role in certain parasitic infections. Specifically, some helminth (parasitic worm) species use larval forms to infect human hosts. These invasions may lead to conditions such as cutaneous larva migrans, visceral larva migrans, or gnathostomiasis, depending on the specific parasite involved and the location of the infection within the body.

The larval stage is characterized by its markedly different morphology and behavior compared to the adult form. Larvae often have a distinct appearance, featuring unsegmented bodies, simple sense organs, and undeveloped digestive systems. They are typically adapted for a specific mode of life, such as free-living or parasitic existence, and rely on external sources of nutrition for their development.

In the context of helminth infections, larvae may be transmitted to humans through various routes, including ingestion of contaminated food or water, direct skin contact with infective stages, or transmission via an intermediate host (such as a vector). Once inside the human body, these parasitic larvae can cause tissue damage and provoke immune responses, leading to the clinical manifestations of disease.

It is essential to distinguish between the medical definition of 'larva' and its broader usage in biology and zoology. In those fields, 'larva' refers to any juvenile form that undergoes metamorphosis before reaching adulthood, regardless of whether it is parasitic or not.

Chemoreceptor cells are specialized sensory neurons that detect and respond to chemical changes in the internal or external environment. They play a crucial role in maintaining homeostasis within the body by converting chemical signals into electrical impulses, which are then transmitted to the central nervous system for further processing and response.

There are two main types of chemoreceptor cells:

1. Oxygen Chemoreceptors: These cells are located in the carotid bodies near the bifurcation of the common carotid artery and in the aortic bodies close to the aortic arch. They monitor the levels of oxygen, carbon dioxide, and pH in the blood and respond to decreases in oxygen concentration or increases in carbon dioxide and hydrogen ions (indicating acidity) by increasing their firing rate. This signals the brain to increase respiratory rate and depth, thereby restoring normal oxygen levels.

2. Taste Cells: These chemoreceptor cells are found within the taste buds of the tongue and other areas of the oral cavity. They detect specific tastes (salty, sour, sweet, bitter, and umami) by interacting with molecules from food. When a tastant binds to receptors on the surface of a taste cell, it triggers a series of intracellular signaling events that ultimately lead to the generation of an action potential. This information is then relayed to the brain, where it is interpreted as taste sensation.

In summary, chemoreceptor cells are essential for maintaining physiological balance by detecting and responding to chemical stimuli in the body. They play a critical role in regulating vital functions such as respiration and digestion.

Alcohol dehydrogenase (ADH) is a group of enzymes responsible for catalyzing the oxidation of alcohols to aldehydes or ketones, and reducing equivalents such as NAD+ to NADH. In humans, ADH plays a crucial role in the metabolism of ethanol, converting it into acetaldehyde, which is then further metabolized by aldehyde dehydrogenase (ALDH) into acetate. This process helps to detoxify and eliminate ethanol from the body. Additionally, ADH enzymes are also involved in the metabolism of other alcohols, such as methanol and ethylene glycol, which can be toxic if allowed to accumulate in the body.

"Beetles" is not a medical term. It is a common name used to refer to insects belonging to the order Coleoptera, which is one of the largest orders in the class Insecta. Beetles are characterized by their hardened forewings, known as elytra, which protect their hind wings and body when not in use for flying.

There are many different species of beetles found all over the world, and some can have an impact on human health. For example, certain types of beetles, such as bed bugs and carpet beetles, can cause skin irritation and allergic reactions in some people. Other beetles, like the Colorado potato beetle, can damage crops and lead to economic losses for farmers. However, it is important to note that most beetles are not harmful to humans and play an essential role in ecosystems as decomposers and pollinators.

Insecticides are substances or mixtures of substances intended for preventing, destroying, or mitigating any pest, including insects, arachnids, or other related pests. They can be chemical or biological agents that disrupt the growth, development, or behavior of these organisms, leading to their death or incapacitation. Insecticides are widely used in agriculture, public health, and residential settings for pest control. However, they must be used with caution due to potential risks to non-target organisms and the environment.

Alcoholism is a chronic and often relapsing brain disorder characterized by the excessive and compulsive consumption of alcohol despite negative consequences to one's health, relationships, and daily life. It is also commonly referred to as alcohol use disorder (AUD) or alcohol dependence.

The diagnostic criteria for AUD include a pattern of alcohol use that includes problems controlling intake, continued use despite problems resulting from drinking, development of a tolerance, drinking that leads to risky behaviors or situations, and withdrawal symptoms when not drinking.

Alcoholism can cause a wide range of physical and psychological health problems, including liver disease, heart disease, neurological damage, mental health disorders, and increased risk of accidents and injuries. Treatment for alcoholism typically involves a combination of behavioral therapies, medications, and support groups to help individuals achieve and maintain sobriety.

Brachyura is a term used in the classification of crustaceans, specifically referring to a group of decapods known as "true crabs." This infraorder includes a wide variety of crab species that are characterized by having a short and broad abdomen, which is typically tucked under the thorax and protected by the shell.

The term Brachyura comes from the Greek words "brachys," meaning short, and "oura," meaning tail. This refers to the reduced abdomen that distinguishes this group of crabs from other decapods such as shrimps, lobsters, and crayfish.

Brachyura species are found in a wide range of habitats, including freshwater, marine, and terrestrial environments. They can be found all over the world, with some species adapted to live in extreme conditions such as deep-sea hydrothermal vents or intertidal zones. Some well-known examples of Brachyura include the blue crab (Callinectes sapidus), the European shore crab (Carcinus maenas), and the coconut crab (Birgus latro).

Herbivory is not a medical term, but rather a term used in biology and ecology. It refers to the practice of consuming plants or plant matter for food. Herbivores are animals that eat only plants, and their diet can include leaves, stems, roots, flowers, fruits, seeds, and other parts of plants.

While herbivory is not a medical term, it is still relevant to the field of medicine in certain contexts. For example, understanding the diets and behaviors of herbivores can help inform public health initiatives related to food safety and disease transmission. Additionally, research on herbivory has contributed to our understanding of the evolution of plant-animal interactions and the development of ecosystems.

Ethanol is the medical term for pure alcohol, which is a colorless, clear, volatile, flammable liquid with a characteristic odor and burning taste. It is the type of alcohol that is found in alcoholic beverages and is produced by the fermentation of sugars by yeasts.

In the medical field, ethanol is used as an antiseptic and disinfectant, and it is also used as a solvent for various medicinal preparations. It has central nervous system depressant properties and is sometimes used as a sedative or to induce sleep. However, excessive consumption of ethanol can lead to alcohol intoxication, which can cause a range of negative health effects, including impaired judgment, coordination, and memory, as well as an increased risk of accidents, injuries, and chronic diseases such as liver disease and addiction.

I believe there may be a slight misunderstanding in your question. "Plant leaves" are not a medical term, but rather a general biological term referring to a specific organ found in plants.

Leaves are organs that are typically flat and broad, and they are the primary site of photosynthesis in most plants. They are usually green due to the presence of chlorophyll, which is essential for capturing sunlight and converting it into chemical energy through photosynthesis.

While leaves do not have a direct medical definition, understanding their structure and function can be important in various medical fields, such as pharmacognosy (the study of medicinal plants) or environmental health. For example, certain plant leaves may contain bioactive compounds that have therapeutic potential, while others may produce allergens or toxins that can impact human health.

I believe there may be some confusion in your question. "Moths" are not a medical term, but rather they are a group of insects closely related to butterflies. They belong to the order Lepidoptera and are characterized by their scales covering their wings and body. If you have any questions about moths or if you meant to ask something else, please let me know!

I apologize for any confusion, but "insects" are not a medical term. Insects are small air-breathing arthropods that have a segmented body with six legs and usually have wings. They make up the largest group of animals on Earth, with over a million described species.

If you're looking for information about a specific medical condition or topic, please provide more details so I can offer a relevant response.

Fetal Alcohol Spectrum Disorders (FASD) is a term used to describe a range of effects that can occur in an individual whose mother drank alcohol during pregnancy. These effects may include physical, mental, and behavioral abnormalities, and can vary in severity and combination from one individual to another.

The four diagnostic categories within FASD are:

1. Fetal Alcohol Syndrome (FAS): This is the most severe form of FASD and is characterized by a specific pattern of facial features, growth deficiencies, and central nervous system dysfunction.
2. Partial Fetal Alcohol Syndrome (pFAS): This category includes individuals who have some, but not all, of the features of FAS.
3. Alcohol-Related Neurodevelopmental Disorder (ARND): This category includes individuals who have functional or cognitive impairments due to prenatal alcohol exposure, but do not meet the criteria for FAS or pFAS.
4. Alcohol-Related Birth Defects (ARBD): This category includes individuals who have physical birth defects due to prenatal alcohol exposure.

It is important to note that FASD is a completely preventable condition, and there is no known safe amount or safe time to drink alcohol during pregnancy.

A plant extract is a preparation containing chemical constituents that have been extracted from a plant using a solvent. The resulting extract may contain a single compound or a mixture of several compounds, depending on the extraction process and the specific plant material used. These extracts are often used in various industries including pharmaceuticals, nutraceuticals, cosmetics, and food and beverage, due to their potential therapeutic or beneficial properties. The composition of plant extracts can vary widely, and it is important to ensure their quality, safety, and efficacy before use in any application.

Alcoholic beverages are drinks that contain ethanol (ethyl alcohol), which is produced by the fermentation of yeast, sugars, and starches. The amount of alcohol in a drink is measured in terms of "alcohol content" or "alcohol by volume" (ABV). Different types of alcoholic beverages include:

1. Beer: A fermented beverage made from grains, such as barley, wheat, or rye. The alcohol content of beer typically ranges from 3-6% ABV.
2. Wine: A fermented beverage made from grapes or other fruits. The alcohol content of wine usually falls between 10-15% ABV.
3. Spirits (or liquors): Distilled beverages with higher alcohol content, typically ranging from 40-50% ABV. Examples include vodka, whiskey, rum, gin, and tequila.
4. Fortified wines: Wines that have had a distilled spirit added to them, increasing their alcohol content. Examples include port, sherry, and madeira, which typically contain 17-20% ABV.
5. Malt beverages: Fermented beverages made from malted barley or other grains, with additional flavorings or sweeteners. These can range in alcohol content from around 4-8% ABV.

It is important to note that excessive consumption of alcoholic beverages can lead to various health issues, including addiction, liver disease, and an increased risk of accidents and injuries. Moderate drinking is generally defined as up to one drink per day for women and up to two drinks per day for men, although individual tolerance and sensitivity to alcohol may vary.

Alcoholic intoxication, also known as alcohol poisoning, is a condition that occurs when a person consumes a large amount of alcohol in a short period of time. This can lead to an increase in the concentration of alcohol in the blood, which can affect the normal functioning of the body's organs and systems.

The symptoms of alcoholic intoxication can vary depending on the severity of the condition, but they may include:

* Confusion or disorientation
* Slurred speech
* Poor coordination
* Staggering or difficulty walking
* Vomiting
* Seizures
* Slow or irregular breathing
* Low body temperature (hypothermia)
* Pale or blue-tinged skin
* Unconsciousness or coma

Alcoholic intoxication can be a medical emergency and requires immediate treatment. If you suspect that someone has alcohol poisoning, it is important to seek medical help right away. Treatment may include supportive care, such as providing fluids and oxygen, and monitoring the person's vital signs. In severe cases, hospitalization may be necessary.

It is important to note that alcoholic intoxication can occur even at relatively low levels of alcohol consumption, especially in people who are not used to drinking or who have certain medical conditions. It is always best to drink in moderation and to be aware of the potential risks associated with alcohol consumption.

Alcohol oxidoreductases are a class of enzymes that catalyze the oxidation of alcohols to aldehydes or ketones, while reducing nicotinamide adenine dinucleotide (NAD+) to NADH. These enzymes play an important role in the metabolism of alcohols and other organic compounds in living organisms.

The most well-known example of an alcohol oxidoreductase is alcohol dehydrogenase (ADH), which is responsible for the oxidation of ethanol to acetaldehyde in the liver during the metabolism of alcoholic beverages. Other examples include aldehyde dehydrogenases (ALDH) and sorbitol dehydrogenase (SDH).

These enzymes are important targets for the development of drugs used to treat alcohol use disorder, as inhibiting their activity can help to reduce the rate of ethanol metabolism and the severity of its effects on the body.

Benzyl alcohol is an aromatic alcohol with the chemical formula C6H5CH2OH. It is a colorless liquid with a mild, pleasant odor and is used as a solvent and preservative in cosmetics, medications, and other products. Benzyl alcohol can also be found as a natural component of some essential oils, fruits, and teas.

Benzyl alcohol is not typically considered a "drug" or a medication, but it may have various pharmacological effects when used in certain medical contexts. For example, it has antimicrobial properties and is sometimes used as a preservative in injectable medications to prevent the growth of bacteria and fungi. It can also be used as a local anesthetic or analgesic in some topical creams and ointments.

It's important to note that benzyl alcohol can be harmful or fatal to infants and young children, especially when it is used in high concentrations or when it is introduced into the body through intravenous (IV) routes. Therefore, it should be used with caution in these populations and only under the guidance of a healthcare professional.

In medical terms, the mouth is officially referred to as the oral cavity. It is the first part of the digestive tract and includes several structures: the lips, vestibule (the space enclosed by the lips and teeth), teeth, gingiva (gums), hard and soft palate, tongue, floor of the mouth, and salivary glands. The mouth is responsible for several functions including speaking, swallowing, breathing, and eating, as it is the initial point of ingestion where food is broken down through mechanical and chemical processes, beginning the digestive process.

'Animal behavior' refers to the actions or responses of animals to various stimuli, including their interactions with the environment and other individuals. It is the study of the actions of animals, whether they are instinctual, learned, or a combination of both. Animal behavior includes communication, mating, foraging, predator avoidance, and social organization, among other things. The scientific study of animal behavior is called ethology. This field seeks to understand the evolutionary basis for behaviors as well as their physiological and psychological mechanisms.

Benzyl alcohol is a aromatic alcohol with the chemical formula C6H5CH2OH. It is a colorless liquid with a characteristic, mildly unpleasant odor. Benzyl alcohol is used as a solvent and as an intermediate in the production of other chemicals. In medicine, it is used as a local anesthetic and antimicrobial agent. It can be found in some personal care products, such as cosmetics, shampoos, and sunscreens, as well as in topical medications and intravenous medications.

According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), alcohol-related disorders are a category of mental disorders defined by a problematic pattern of alcohol use that leads to clinically significant impairment or distress. The disorders include:

1. Alcohol Use Disorder (AUD): A chronic relapsing brain disorder characterized by an impaired ability to stop or control alcohol use despite adverse social, occupational, or health consequences. AUD can be mild, moderate, or severe, and recovery is possible regardless of severity. The symptoms include problems controlling intake of alcohol, continued use despite problems resulting from drinking, development of a tolerance, drinking that leads to risky situations, or withdrawal symptoms when not drinking.
2. Alcohol Intoxication: A state of acute impairment in mental and motor function caused by the recent consumption of alcohol. The symptoms include slurred speech, unsteady gait, nystagmus, impaired attention or memory, stupor, or coma. In severe cases, it can lead to respiratory depression, hypothermia, or even death.
3. Alcohol Withdrawal: A syndrome that occurs when alcohol use is heavily reduced or stopped after prolonged and heavy use. The symptoms include autonomic hyperactivity, increased hand tremor, insomnia, nausea or vomiting, transient visual, tactile, or auditory hallucinations or illusions, psychomotor agitation, anxiety, and grand mal seizures.
4. Other Alcohol-Induced Disorders: These include alcohol-induced sleep disorder, alcohol-induced sexual dysfunction, and alcohol-induced major neurocognitive disorder.

It is important to note that alcohol use disorders are complex conditions that can be influenced by a variety of factors, including genetics, environment, and personal behavior. If you or someone you know is struggling with alcohol use, it is recommended to seek professional help.

Central Nervous System (CNS) depressants are a class of drugs that slow down the activity of the CNS, leading to decreased arousal and decreased level of consciousness. They work by increasing the inhibitory effects of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain, which results in sedation, relaxation, reduced anxiety, and in some cases, respiratory depression.

Examples of CNS depressants include benzodiazepines, barbiturates, non-benzodiazepine hypnotics, and certain types of pain medications such as opioids. These drugs are often used medically to treat conditions such as anxiety, insomnia, seizures, and chronic pain, but they can also be misused or abused for their sedative effects.

It is important to use CNS depressants only under the supervision of a healthcare provider, as they can have serious side effects, including addiction, tolerance, and withdrawal symptoms. Overdose of CNS depressants can lead to coma, respiratory failure, and even death.

Fatty alcohols, also known as long-chain alcohols or long-chain fatty alcohols, are a type of fatty compound that contains a hydroxyl group (-OH) and a long alkyl chain. They are typically derived from natural sources such as plant and animal fats and oils, and can also be synthetically produced.

Fatty alcohols can vary in chain length, typically containing between 8 and 30 carbon atoms. They are commonly used in a variety of industrial and consumer products, including detergents, emulsifiers, lubricants, and personal care products. In the medical field, fatty alcohols may be used as ingredients in certain medications or topical treatments.

I'm sorry for any confusion, but "United States" is a geopolitical entity, specifically the name of the country consisting of 50 states, and it is not a medical term or concept. Therefore, I can't provide a medical definition for it. If you have any questions related to health, medicine, or biology, I would be happy to try to help answer those!

I'm sorry for any confusion, but "Polyvinyl Alcohol" is not a medical term. It is a chemical compound used in various industrial and commercial applications, including the production of adhesives, paints, and medical devices. Polyvinyl Alcohol is a type of synthetic polymer made from the polymerization of vinyl acetate monomer, followed by alcoholysis to replace the acetate groups with hydroxyl groups.

In a medical context, Polyvinyl Alcohol might be used in certain medical devices or applications, such as contact lenses, eye drops, and drug delivery systems, due to its biocompatibility and resistance to protein absorption. However, it is not a term commonly used to describe a medical condition or treatment.

A questionnaire in the medical context is a standardized, systematic, and structured tool used to gather information from individuals regarding their symptoms, medical history, lifestyle, or other health-related factors. It typically consists of a series of written questions that can be either self-administered or administered by an interviewer. Questionnaires are widely used in various areas of healthcare, including clinical research, epidemiological studies, patient care, and health services evaluation to collect data that can inform diagnosis, treatment planning, and population health management. They provide a consistent and organized method for obtaining information from large groups or individual patients, helping to ensure accurate and comprehensive data collection while minimizing bias and variability in the information gathered.

In the context of medicine and health, "temperance" refers to moderation or self-restraint in the consumption of potentially harmful substances, particularly alcohol. It promotes a balanced lifestyle that avoids excessive habits, such as overeating, substance abuse, or any other activities that could negatively impact one's health.

However, it is important to note that "temperance" itself is not a medical term per se but has been used in various historical and social contexts related to health promotion and disease prevention.

Alcohol withdrawal delirium, also known as delirium tremens (DTs), is a serious and potentially life-threatening complication that can occur in people who are dependent on alcohol and suddenly stop or significantly reduce their consumption. It is a form of alcohol withdrawal syndrome that is characterized by the sudden onset of severe confusion, agitation, hallucinations, tremors, and autonomic hyperactivity.

The diagnostic criteria for alcohol withdrawal delirium, as outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), include:

1. Disturbance in consciousness (i.e., reduced clarity of awareness of the environment) with reduced ability to focus, sustain, or shift attention.
2. A change in cognition (such as memory deficit, disorientation, or language disturbance) or the development of a perceptual disturbance that is not better explained by another medical condition or substance use disorder.
3. The disturbance develops over a short period of time (usually hours to a few days) and tends to fluctuate throughout the day.
4. There is evidence from the history, physical examination, or laboratory findings that the symptoms are caused by alcohol withdrawal.
5. The symptoms cannot be better explained by another medical condition, medication use, or substance intoxication or withdrawal.

Alcohol withdrawal delirium is a medical emergency and requires immediate treatment in a hospital setting. Treatment typically involves the use of medications to manage symptoms, such as benzodiazepines to reduce agitation and prevent seizures, and antipsychotic medications to treat hallucinations and delusions. Supportive care, such as fluid and electrolyte replacement, may also be necessary to prevent dehydration and other complications.

Binge drinking is a pattern of alcohol consumption that brings blood alcohol concentration (BAC) levels to 0.08 g/dL or above. For the typical adult, this corresponds to consuming 5 or more drinks (male), or 4 or more drinks (female), in about 2 hours.

It is a serious and dangerous form of alcohol consumption as it can lead to various negative health consequences such as injuries, violence, liver disease, heart disease, and sexually transmitted diseases, among others. Binge drinking is also associated with an increased risk of alcohol dependence.
