Can addictive behaviour be altered? The concept of drug-evoked synaptic plasticity

This summary is based on the article published in the Journal of Neuroscience: Drug-Evoked Synaptic Plasticity Causing Addictive Behavior (November 2013) Context The core element of the addiction process: an initially neutral stimulus becomes attractive when associated with drug consumption, and even after prolonged periods of abstinence this cue may trigger craving and cause the subject to relapse. Therefore, many researchers have argued that the secret to understanding addiction lies in the elucidation of the “memory trace” that links the cue to the compulsive drug use. The implicit underlying hypothesis is that addictive drugs generate an inappropriate learning signal that leads to the encoding of a unique trace, which, when reactivated, has ...

How do you manage a severely disabled and G tube-fed patient?

This question was submitted by a general dentist: Is there a resource with current information on appropriate oral care for severely disabled and G tube-fed population? There are many position papers and guidelines indicating that this population needs care. However, I found only limited information on the actual clinical treatment provided to them and on what the treatment goals should be. These patients often present with gross calculus, limited cooperative ability for professional cleaning, and present with the risk of an aspiration pneumonia. Any attempt to clean the teeth in the office is limited at best, then the question is: what ...

Primary failure of tooth eruption: what is the etiology, diagnosis, and treatment?

This summary is based on the article published in the Dental and Medical Problems journal: Primary Failure of Tooth Eruption – Etiology, Diagnosis and Treatment (Issue 50 (3) 2013) Context  Primary failure of eruption (PFE) is a rare condition that involves impeded eruption of teeth despite the lack of an identified local or general causative factor. Since molar teeth are mainly concerned, a typical clinical image presents extensive lateral open bite. A characteristic radiological feature depicts large radiolucent fields around embedded tooth germs. Research performed in recent years has provided evidence that a defect of the eruption mechanism on a genetic background is responsible for ...
