Painkilling overdose risk for infants when parents misjudge how much they should have
Source: Medical News Today
Parents who give young children prescription painkillers should take extra care to make sure they give just the right amount. The dose given to them by the pharmacy could be too high. Researchers recently identified the top 19 narcotic-containing drugs prescribed to children ages 0-36 months. They calculated the expected daily dose of the narcotic based on an estimate of the child's weight, age and gender. Then they compared that dosage with the actual amount of painkiller dispensed by the pharmacy. Results showed that 4.1 percent of all children received an overdose amount.

Meditation produces powerful pain-relieving effects in the brain, according to new research. Researchers report a big effect – about a 40 percent reduction in pain intensity and a 57 percent reduction in pain unpleasantness. Meditation produced a greater reduction in pain than even morphine or other pain-relieving drugs, which typically reduce pain ratings by about 25 percent.

People with a chronic condition may find themselves taking on a more active role in maintaining or improving their own health if there is an ongoing relationship with a primary healthcare (PHC) provider, according to new research. One aspect of care that is especially important for individuals with chronic pain is having enough time to talk with their physician. Other important aspects are communication, patient-centered decision-making and being treated as a whole person.

Research uncovers an unknown side effect of a promising drug for acute chronic pain
April 27, 2011 Source: Children's National Medical Center
Researchers have discovered that resiniferatoxin, a drug that has shown early promise as an option for chronic, severe pain sufferers, may decrease the body's ability to fight off bacterial infections, particularly sepsis. The study sheds new light on the role of a pain receptor, transient receptor potential vanilloid-1 (TRPV1), and how medications designed to impact this receptor's relay of the pain sensation to the brain might work in humans.

The positive effects of mindfulness meditation on pain and working memory may result from an improved ability to regulate a crucial brain wave called the alpha rhythm, which is thought to "turn down the volume" on distracting information. Researchers report that modulation of the alpha rhythm in response to attention-directing cues was faster and significantly more enhanced among study participants in an 8 week mindfulness meditation program than in the control group.

In a new evidence based guideline, strong evidence shows the seizure drug pregabalin is effective in treating diabetic nerve pain and can improve quality of life. Doctors, however, should determine if it is appropriate for their patients on a case-by-case basis. In addition, the guideline notes that several other treatment options are probably effective and should be considered.

Study to improve management of cancer pain in African Americans
April 12, 2011 Source: Wayne State University
African American cancer patients experience higher pain levels, resulting from a lower feeling of control over pain and a need for help with pain management. Pain care must be highly individualized and responsive to the rapidly changing needs of patients and caregivers trying to manage pain and symptoms at home. This is especially important because patients and caregivers are increasingly responsible for daily pain and symptom management due to shorter hospital stays.

How grown children cope with pain may be traced back to the way their family copes with pain
April 11, 2011 Source: Springer
A new study found that parents' pain catastrophizing scores predicted their adult children's scores, irrespective of the level of actual pain experienced by the adult patients. Since during childhood parents serve as a model that children imitate, it is possible that children use social and communicative tools that they have observed in their parents, to manage their own distress in a similar context. Families may develop a specific cognitive style of dealing with pain.

A new study suggests a connection between migraine headaches in children and a heart defect called patent foramen ovale (a common defect in the wall between the two upper chambers of the heart), which affects 25% of people in the United States. Of the studied children who had migraines with aura, 50% also had a PFO; this is nearly double the PFO rate of the general population. However, only 25% of children who had migraines without aura had a PFO.
