Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

164
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Drug Dependence01:17

Drug Dependence

1.0K
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...

Drug Abuse and Addiction: Pharmacological Phenomena

465
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Drugs for Treatment of Diarrhea-Predominant IBS

159
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Bulimia Nervosa01:30

Bulimia Nervosa

64
Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...

Drugs for Treatment of Constipation-Predominant IBS

157
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...

Area of Science:

  • Neurology
  • Radiology
  • Toxicology

Background:

  • Marchiafava-Bignami disease (MBD) is a rare neurological disorder typically associated with chronic alcohol consumption and malnutrition.
  • It involves demyelination and necrosis, primarily affecting the corpus callosum, and presents with diverse neurological symptoms.
  • Magnetic resonance imaging (MRI) is the most sensitive diagnostic tool, revealing characteristic changes in the corpus callosum.

Observation:

  • A 27-year-old male with a history of polysubstance use disorder presented with subacute neurological deterioration.
  • Clinical and imaging findings were consistent with Marchiafava-Bignami disease.
  • MRI revealed demyelination specifically in the splenium of the corpus callosum.

Findings:

  • The case demonstrates an unusual presentation of Marchiafava-Bignami disease in an individual with polysubstance use disorder.
  • This finding expands the known etiological spectrum of MBD beyond chronic alcoholism.
  • Subacute neurological decline and corpus callosum demyelination were key diagnostic indicators.

Implications:

  • The case underscores the importance of considering MBD in patients with neurological deterioration and substance use disorders, even in younger individuals.
  • It suggests that polysubstance abuse may be an underrecognized risk factor or contributing element in the pathogenesis of MBD.
  • Further research is warranted to explore the relationship between polysubstance abuse and MBD presentation and outcomes.
