Anorexia Nervosa01:28

Anorexia Nervosa

2.0K
Anorexia nervosa is a complex and severe eating disorder characterized by an intense fear of weight gain, an unrelenting pursuit of thinness, and a distorted body image. It often leads to dangerously low body weight relative to an individual's age and height. This disorder is marked by significant physical and psychological consequences, making it one of the most life-threatening psychiatric illnesses.

Bulimia Nervosa

1.1K
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...

Overview of Protein Metabolism

4.8K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Disorders of Erythrocytes01:27

Disorders of Erythrocytes

2.9K
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...

Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

1.0K
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

261
In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...

Summary

Acute intermittent porphyria (AIP) can cause paralysis and is linked to anorexia nervosa. Treating eating disorders is key to breaking a dangerous cycle of recurrent porphyria attacks.

Area of Science:

  • Biochemistry
  • Neurology
  • Psychiatry

Background:

  • Porphyrias are hereditary heme biosynthesis disorders with diverse symptoms.
  • Acute intermittent porphyria (AIP) is a common subtype, often presenting with psychiatric issues.

Observation:

  • A patient experienced acute flaccid paralysis following significant weight loss due to anorexia nervosa.
  • Neurologic evaluation confirmed a diagnosis of AIP.

Findings:

  • This case highlights a detrimental cycle between AIP and anorexia nervosa.
  • Porphyria may precipitate anorexia, while restrictive diets in anorexia can trigger porphyric crises.

Implications:

  • Interrupting this cycle through psychiatric intervention for eating disorders is vital for effective long-term management of AIP.
  • Early recognition of this interplay is crucial for patient outcomes.
