New research presented today shows that formation of new neurons in the hippocampus - a brain region known for its importance in learning and remembering - could cause forgetting of old memories by causing a reorganization of existing brain circuits. Drs. Paul Frankland and Sheena Josselyn, both from the Hospital for Sick Children in Toronto, argue this reorganization could have the positive effect of clearing old memories, reducing interference and thereby increasing capacity for new learning. These results were presented at the 2013 Canadian Neuroscience Meeting, the annual meeting of the Canadian Association for Neuroscience - Association Canadienne des Neurosciences (CAN-ACN). http://medicalxpress.com/news/2013-05-neuron-formation-capacity-expense-memories.html Neuroscience Fri, 24 May 2013 09:30:03 EST news288605755 As parents, physicians and policymakers look for ways to curb childhood obesity, they may need to look no further than a child's own backyard. http://medicalxpress.com/news/2013-05-childhood-obesity-home.html Overweight and Obesity Sat, 04 May 2013 05:20:01 EST news286860678 Researchers at the University Department of Neurology at the MedUni Vienna have identified a gene behind an epilepsy syndrome, which could also play an important role in other idiopathic (genetically caused) epilepsies. With the so-called "next generation sequencing", with which genetic changes can be identified within a few days, it was ascertained that the CNTN2 gene is defective in this type of epilepsy. http://medicalxpress.com/news/2013-04-discovery-genetic-defect-triggers-epilepsy.html Neuroscience Wed, 17 Apr 2013 10:00:01 EST news285410882 For the first time, teams that care for children needing heart surgery have been able to review their short-term success rate better across all the different operations they perform. http://medicalxpress.com/news/2013-04-child-heart-surgeons-access-clearer.html Cardiology Fri, 05 Apr 2013 07:20:01 EST news284362875 (HealthDay)—Parent behavior training is an effective and well-studied intervention for preschoolers at risk of developing attention-deficit/hyperactivity disorder (ADHD), a new review shows. http://medicalxpress.com/news/2013-04-parent-focused-classes-tots-adhd.html Attention deficit disorders Mon, 01 Apr 2013 11:30:01 EST news284031544 Physicians and parents must be aware of the growing danger of magnet ingestion by children because magnets can adhere to each other and cause life-threatening problems such as bowel perforations, a new case study illustrates in CMAJ. http://medicalxpress.com/news/2013-03-magnet-ingestion-young-children-problem.html Pediatrics Mon, 11 Mar 2013 12:00:01 EST news282221348 `In a study to be presented on February 14 at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in San Francisco, California, researchers will present data showing the effectiveness of preemptive treatment for hyperemesis gravidarum and severe morning sickness. http://medicalxpress.com/news/2013-02-preemptive-treatment-severe-morning-sickness.html Obstetrics & gynaecology Mon, 11 Feb 2013 10:36:41 EST news279800895 (HealthDay)—With flu widespread throughout the United States this season, businesses need to prepare to deal with productivity challenges, a doctor advises. http://medicalxpress.com/news/2013-01-businesses-flu-disruptions-doctor.html Health Fri, 18 Jan 2013 14:10:01 EST news277736495 Taking a vitamin D supplement and drinking cow's milk are the two most important factors that determine how much vitamin D is in a child's body, new research has found. http://medicalxpress.com/news/2013-01-supplements-cow-biggest-roles-vitamin.html Pediatrics Mon, 14 Jan 2013 17:18:49 EST news277406323 For individuals with agonizing pain, it is a cruel blow when the gold-standard medication actually causes more pain.

But the death of an infant exposed to codeine through breast milk has many health care providers questioning the safety of the drug when used by breastfeeding mothers. Because of the potential risks, some doctors have begun the practice of prescribing oxycodone as an alternative to codeine; however, a new study soon to be published in The Journal of Pediatrics finds that oxycodone is no safer for breastfed infants than codeine. http://medicalxpress.com/news/2011-09-mother-postpartum-oxycodone-safer-breastfed.html Health Tue, 06 Sep 2011 12:13:01 EST news234529962 New research focusing on high-frequency oscillations, termed ripples and fast ripples, recorded by intracranial electroencephalography (EEG), may provide an important marker for the localization of the brain region responsible for seizure activity.
