Using the Activity-based Anorexia Rodent Model to Study the Neurobiological Basis of Anorexia Nervosa
Published on: October 22, 2015
Summary
Niacin treatment effectively resolved skin manifestations in a patient with concurrent pellagra and anorexia nervosa. This highlights niacin
Area of Science:
- Nutritional Biochemistry
- Dermatology
- Psychiatry
Background:
- Pellagra, a deficiency disease caused by niacin (vitamin B3) lack, presents with dermatitis, diarrhea, and dementia.
- Anorexia nervosa is a complex eating disorder characterized by self-starvation and a distorted body image.
Observation:
- A 20-year-old female presented with a six-month history of both pellagra and anorexia nervosa.
- The patient exhibited characteristic skin lesions associated with pellagra.
Findings:
- Treatment with niacin supplementation led to the complete resolution of the pellagra-related skin changes.
- This suggests a direct link between niacin deficiency and the observed dermatological symptoms.
Implications:
- Niacin repletion is a crucial therapeutic intervention for pellagra, even in the context of complex psychiatric comorbidities.
- Early identification and management of nutritional deficiencies are vital in patients with eating disorders to prevent severe health consequences.

01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

01:20Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
01:30Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:28Anorexia Nervosa
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.

01:30Bulimia Nervosa
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...
