薰果花优愉悦五感

香熏美容是一种古老的治疗方法，从古埃及艳后克娄芭特拉用玫瑰铺满寝宫，到我国唐代杨黄妃用鲜花浸泡沐浴就可窥见一斑。甚至古代统治者在登基、祭祀、加冕等重大仪式时，香熏都是不可缺少的一道程序。     

痛，并快乐着 中医养生疗法新触感

不疼,是健康是快乐,疼,也是健康,也是快乐,现在让我们看一看乐活族的“疼痛”新理念。老李其实并不老,三十出头,四十往下,偏偏就是身体不大好,看着像个小老头,大家便称他为老李。老李是怕疼的人,最讨厌什么按摩啦刮痧啦的什么,尤其是看到有的人刮痧后,胳膊上或者后背上那一道道红紫紫的斑痕,心里就会惊得一跳一跳的,用他的话说就是像被人用皮带抽到心脏上一样。     

Recreational ketamine: from pleasure to pain

Ketamine has become increasingly recognized as a drug of recreational use. Individuals using significant amounts have developed symptoms including a small painful bladder, ureteric obstruction, papillary necrosis and hepatic dysfunction. The present paper examines the current literature on the relationship between ketamine use and these symptoms. Our own clinical experience and the data available clarify the causal relationship, and further data help to elucidate the mechanism of damage. On the basis of continued work and development with patients who are ketamine users we suggest an assessment and treatment regime that includes cessation of ketamine use and adequate analgesia to overcome symptoms. In conclusion, it is important for medical practitioners who encounter patients with these symptoms to ask about recreational drug use. Ketamine remains a safe and effective drug to use under appropriate medical supervision. Patients identified as suffering from this syndrome will need to be referred to a urological unit with an interest in the treatment of the condition.     

Hand injuries at leisure

In a survey of 383 moderate and severe hand injuries in adults, 246 (64.4%) occurred outwith work. Falling (sixty-four patients) and punching (forty-eight patients) were the commonest mechanisms of blunt injury. Glass (eight), knives (seven) and "do-it-yourself" materials (eight) were most frequently implicated in sharp trauma. No outstandingly dangerous hobbies or social activities were identified.     

Home and leisure activities and childhood knee injuries

AIM: To assess the relative occurrence of non motor-vehicle knee injuries and identify important clusters that can be targeted for preventive interventions. METHODS: The study subjects covered 2167 children (0-14 years) who suffered non motor-vehicle knee injuries out of 66870 registered during a three-year period in an established Emergency Department Injury Surveillance System (EDISS). A more serious joint injury was identified in 263 (12%) children, whereas the remaining 1904 children had only soft tissue knee injuries. RESULTS: The incidence of non motor-vehicle knee injuries was estimated at 6.5 per 1000 children-years. Both the incidence of knee injuries and the male-to-female ratio increase with increasing age, reflecting the gender and age pattern of physical activity. Three clusters were identified: The first consisted of more serious knee injuries among older children, frequently resulting after a fall from stairs or a collision in school during winter months; the second cluster consisted of rather minor knee injuries occurring mostly among younger girls at home or in playgrounds, following a fall after stumbling or hit by an object while playing, especially during the summer; the third cluster comprised injuries among older boys, sustained mainly subsequent to overexertion in a sports area. CONCLUSION: Knee injuries tend to be more common among boys but more serious among girls. More and less serious knee injuries tend to fall into distinct clusters that could facilitate prioritization of preventive measures.     

Brain stimulation and reward: "pleasure centers" after twenty-five years.

"Self-stimulation" is a phenomenon whereby an animal (including a human being) will repeatedly stimulate its brain electrically, sometimes to the point of exhaustion. This phenomenon is robust and readily reproducible in many areas of the brain, particularly in nuclei and fiber tracts known to be monoaminergic, and it has been the basis for the study of reinforcement and learning mechanisms in the brain. The last 25 years of work on intracranial self-stimulation is reviewed with an emphasis on mechanisms, primarily catecholaminergic. Implications for learning and pain mechanisms are discussed.
