Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol that is rapidly distributed in the body and brain. Ethanol alters many neurochemical systems and has rewarding and addictive properties. It is the oldest recreational drug and likely contributes to more morbidity, mortality, and public health costs than all illicit drugs combined. The 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) integrates alcohol abuse and alcohol dependence into a single disorder called alcohol use disorder (AUD), with mild, moderate, and severe subclassifications (American Psychiatric Association, 2013). In the DSM-5, all types of substance abuse and dependence have been combined into a single substance use disorder (SUD) on a continuum from mild to severe. A diagnosis of AUD requires that at least two of the 11 DSM-5 behaviors be present within a 12-month period (mild AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria). The four main behavioral effects of AUD are impaired control over drinking, negative social consequences, risky use, and altered physiological effects (tolerance, withdrawal). This chapter presents an overview of the prevalence and harmful consequences of AUD in the U.S., the systemic nature of the disease, neurocircuitry and stages of AUD, comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and pharmacotherapies for AUD.

Physiology of Special Chemical Sensation of Taste

MedicoseAcademics

Title: Sense of Taste Presenter: Dr. Faiza, Assistant Professor of Physiology Qualifications: MBBS (Best Graduate, AIMC Lahore) FCPS Physiology ICMT, CHPE, DHPE (STMU) MPH (GC University, Faisalabad) MBA (Virtual University of Pakistan) Learning Objectives: Describe the structure and function of taste buds. Describe the relationship between the taste threshold and taste index of common substances. Explain the chemical basis and signal transduction of taste perception for each type of primary taste sensation. Recognize different abnormalities of taste perception and their causes. Key Topics: Significance of Taste Sensation: Differentiation between pleasant and harmful food Influence on behavior Selection of food based on metabolic needs Receptors of Taste: Taste buds on the tongue Influence of sense of smell, texture of food, and pain stimulation (e.g., by pepper) Primary and Secondary Taste Sensations: Primary taste sensations: Sweet, Sour, Salty, Bitter, Umami Chemical basis and signal transduction mechanisms for each taste Taste Threshold and Index: Taste threshold values for Sweet (sucrose), Salty (NaCl), Sour (HCl), and Bitter (Quinine) Taste index relationship: Inversely proportional to taste threshold Taste Blindness: Inability to taste certain substances, particularly thiourea compounds Example: Phenylthiocarbamide Structure and Function of Taste Buds: Composition: Epithelial cells, Sustentacular/Supporting cells, Taste cells, Basal cells Features: Taste pores, Taste hairs/microvilli, and Taste nerve fibers Location of Taste Buds: Found in papillae of the tongue (Fungiform, Circumvallate, Foliate) Also present on the palate, tonsillar pillars, epiglottis, and proximal esophagus Mechanism of Taste Stimulation: Interaction of taste substances with receptors on microvilli Signal transduction pathways for Umami, Sweet, Bitter, Sour, and Salty tastes Taste Sensitivity and Adaptation: Decrease in sensitivity with age Rapid adaptation of taste sensation Role of Saliva in Taste: Dissolution of tastants to reach receptors Washing away the stimulus Taste Preferences and Aversions: Mechanisms behind taste preference and aversion Influence of receptors and neural pathways Impact of Sensory Nerve Damage: Degeneration of taste buds if the sensory nerve fiber is cut Abnormalities of Taste Detection: Conditions: Ageusia, Hypogeusia, Dysgeusia (parageusia) Causes: Nerve damage, neurological disorders, infections, poor oral hygiene, adverse drug effects, deficiencies, aging, tobacco use, altered neurotransmitter levels Neurotransmitters and Taste Threshold: Effects of serotonin (5-HT) and norepinephrine (NE) on taste sensitivity Supertasters: 25% of the population with heightened sensitivity to taste, especially bitterness Increased number of fungiform papillae

Flu Vaccine Alert in Bangalore Karnataka

addon Scans

As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions. Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says. This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots. To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare. Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself. Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places. Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages. Stay informed, stay safe, and get your flu shot today!
