By DTI LEICESTER, UK: In March 2005, a 38-year-old British soldier sta- tioned in Germany lost his ability toformnewmemoriesafterunder- going a regular root canal treat- ment.Tothisday,heisunabletore- member anything for longer than 90 minutes, although his brain is completelyintactandhesufferedno trauma that could have caused the amnesia,accordingtohisdoctors. “I remember getting into the chair and the dentist inserting the local anaesthetic,” the man, who wishes to remain anonymous, told the BBC. Since that moment, he re- members nothing. Every morning, he wakes up thinking that he is still a soldier stationed in Germany in 2005, waiting to visit the dentist for root canal surgery. The German dentist only re- alised after the treatment, which was without complications, that something was wrong with the pa- tient. He was pale, disoriented and struggled to stand up. As his condi- tiondidnotimprove,hewasbrought tohospitalwherehestayedforsev- eral days. In the beginning, he was not able to remember anything for longer than a few minutes. The doctors’ first suspicion was that a bad reaction to the anaes- thetic had caused a brain haemor- rhage.However,theycouldnotfind any evidence of injury. Finally, the patient and his family returned to England, where Dr Gerald Burgess, a clinical psychologist from Leices- ter, took over the case. According to Burgess, a form of anterograde amnesia would have been the most obvious explana- tionfortheman’scondition.Inthis case, the hippocampi, the brain re- gions responsible for the consoli- dation of information from short- term memory to long-term mem- ory,aredamagedsothatmemories cannolongerbeformedandstored correctly.Yet,theman’sbrainscans showednoabnormalities.Thus,an- other possible explanation would have been a psychogenic illness. Burgess conducted detailed psy- chiatric assessments in order to determine whether the man had suffered any trauma. However, Burgess found that his patient was emotionally healthy and his wife confirmed that there had not been any traumatic events in the man’s lifepriortohisdentistvisitin2005. Burgess continues to research his patient’s rare case of amnesia, currently suspecting that the brain’s synapses might play an im- portant role. Each time a memory is formed and transferred to long- term memory, the synapses are re- built, which involves the produc- tion of new proteins. This protein synthesis might be blocked in the case of Burgess’ patient, keeping himfromgeneratinganynewlong- termmemories.Inordertofurther research his hypothesis, Burgess is examining five similar cases of mysterious memory loss without braindamage from the medical lit- erature. These cases might provide an answer to why the root canal treatment appears to have trig- gered the man’s memory loss. All ofthecasesareinsomewayrelated to a period of psychological stress during a medical emergency. “It could be a genetic predisposition that needs a catalyst event to start the process,”Burgess told the BBC. “One of our reasons for writing upthisindividual’scasewasthatwe had never seen anything like this before in our assessment clinics, and we do not know what to make ofit,butfeltanhonestreportingof the facts as we assessed them was warranted, that perhaps there will beothercases,orpeoplewhoknow morethanwedoaboutwhatmight havecausedthepatient’samnesia,” Burgess stated.

Rare case of amnesia linked to root canal treatment By DTI LONDON, UK: Lately, there have been increasing efforts to curb Britain’s high sugar consumption. Although the British Dental Asso- ciation (BDA) has welcomed Tesco’s recent announcement that it is banning high-sugar drinks from its shelves, the association has called for action that goes further than “symbolic” concessions and urged government to follow the recom- mendations of the report by the Scientific Advisory Committee on Nutrition(SACN). “Finally we’re seeing big retailers waking up to the sugar crisis. That’s progress, but these symbolic ges- tures should not disguise the fact supermarkets are still banking on the nation’s sweet tooth,” Dr Mick Armstrong, Chair of the BDA, said. “The recent obituaries for Capri Sun, Ribena or Percy Pigs are de- signed first and foremost to fill up column inches and Twitter feeds. PR stunts should not blind govern- ment, parents or health practition- erstotheneedforreal,co-ordinated action to address Britain’s addic- tiontosugar,”remarkedArmstrong on Tesco’s plans to take added- sugar drinks out of the children’s juice department starting in Sep- tember. Tesco’s plans echo recent recom- mendations in the Carbohydrates and Health report, published by SACN on 17 July, which advises reducing the daily energy intake of sugars from 10 to 5 per cent. The report also recommends that consumption of sugar-sweetened drinksbeminimisedandoffibrebe increased. According to the health experts, 5 per cent of daily energy intake is the equivalent of 19 g or five sugar cubes for children aged 4–6, 24g or six sugar cubes for children aged 7–10, and 30g or seven sugar cubes for those aged 11 and over, based on averagediets. TheSACNfindings,establishedby agroupofindependentexpertsthat advises government on matters re- lating to diet, nutrition and health, offer the first wide-ranging look at therelationshipbetweensugarcon- sumption and health outcomes in theUKsincethe1990s. Other national statistics have shown that British children espe- cially are consuming unhealthy amounts of free sugars—the nutrient-free refined sugar added to products such as sweetened drinks—intheirdaily diet.At30per cent, soft drinks accounted for the majority of sugar in the diet of 4- to 10-year-olds, the 2014 National DietandNutritionSurveyfound. Soft drinks and juices are espe- cially harmful to the teeth, since they tend to be very acidic, which makestheteethparticularlyvulner- able to both dental decay and tooth erosion. Aside from posing oral healthrisks,adietrichinfreesugars has been linked to obesity and Type 2diabetes,amongotherconditions. With reference to the SACN rec- ommendations, the BDA has called for radical measures to cut Britain’s sugarintake,includingloweringthe recommended daily allowance, and action on marketing, labelling and salestaxes.TheBDAhaslaunchedan online petition addressed to Prime Minister David Cameron, inviting both health professionals and pa- tients to lend support to SACN’s proposalsatChange.org. “We have an historic opportunity here to end Britain’s addiction to sugar. The government now has the evidence and a clear duty to send the strongest possible signal to the food industry, that while added sugar mightbehelpingtheirsales,itishurt- ingtheircustomers,”Armstrongsaid.
