Circulating Omentin-1 and Chronic Painful Temporomandibular Disorders
Journal of Oral & Facial Pain and Headache
|July 30, 2016
Summary
Lower omentin-1 levels are linked to painful temporomandibular disorders (TMD). This suggests inflammation plays a role in TMD pain, offering potential therapeutic targets.
Area of Science:
- Biomedical research
- Inflammation and immunology
- Orofacial pain disorders
Background:
- Temporomandibular disorders (TMD) represent a significant source of orofacial pain.
- The role of specific adipokines, like omentin-1, in TMD pathophysiology remains incompletely understood.
Purpose of the Study:
- To examine the association between circulating omentin-1 levels and the presence of painful temporomandibular disorders (TMD).
Main Methods:
- A case-control study design was employed using data from the OPPERA study.
- Omentin-1 plasma levels were quantified using enzyme-linked immunosorbent assay (ELISA).
- Statistical analysis involved binary logistic regression, adjusting for relevant covariates.
Main Results:
- Initially, the association between omentin-1 and painful TMD was not statistically significant (P = .072).
- After adjusting for covariates, each standard deviation increase in omentin-1 was associated with a 36% decrease in the odds of TMD pain (adjusted OR = 0.64; P = .031).
Conclusions:
- Individuals with painful TMD exhibited significantly lower circulating omentin-1 levels compared to controls.
- These findings suggest that inflammatory pathways, potentially involving omentin-1, are implicated in the mediation of TMD pain.

01:24Chronic Pancreatitis I: Introduction
846
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...
