Kindling has clinical relevance with regard to benzodiazepines; for example, there is an increasing shift to use of benzodiazepines with a shorter half-life and intermittent use, which can result in interdose withdrawal and rebound effects. Cognitive behavioral therapy
Cognitive behavioral therapy has been found to be more effective for the long-term management of insomnia than sedative hypnotic drugs. No formal withdrawal programs for benzodiazepines exists with local providers in the UK. Meta-analysis of published data on psychological treatments for insomnia show a success rate between 70 and 80%. A large-scale trial utilizing cognitive behavioral therapy in chronic users of sedative hypnotics including nitrazepam, temazepam, and zopiclone found CBT to be a significantly more effective long-term treatment for chronic insomnia than sedative hypnotic drugs. Persisting improvements in sleep quality, sleep onset latency, increased total sleep, improvements in sleep efficiency, significant improvements in vitality, physical and mental health at 3-, 6-, and 12-month follow-ups were found in those receiving CBT. A marked reduction in total sedative hypnotic drug use was found in those receiving CBT, with 33% reporting zero hypnotic drug use. Age has been found not to be a barrier to successful outcome of CBT. It was concluded that CBT for the management of chronic insomnia is a flexible, practical, and cost-effective treatment, and it was also concluded that CBT leads to a reduction of benzodiazepine drug intake in a significant number of patients.Chronic use of hypnotic medications is not recommended due to their adverse effects on health and the risk of dependence.
Rubbing or applying force to the affected areas should be avoided as it may cause further damage such as abrasions. The use of ibuprofen and tetanus toxoid is recommended for pain relief or to reduce swelling or inflammation. For severe injuries, iloprost or thrombolytics may be used. Surgery is sometimes necessary. Amputation should be considered a few months after exposure in order to consider whether the extent of injury is permanent damage and thus necessitates drastic treatment.Evidence of frostbite occurring in people dates back 5,000 years. Evidence was documented in a pre-Columbian mummy discovered in the Andes. The number of cases of frostbite is unknown. Rates may be as high as 40% a year among those who mountaineer. The most common age group affected is those 30 to 50 years old. Frostbite has also played an important role in a number of military conflicts. The first formal description of the condition was in 1813 by Dominique Jean Larrey, a physician in Napoleons army, during its invasion of Russia. Signs and symptoms
Areas that are usually affected include cheeks, ears, nose and fingers and toes. Frostbite is often preceded by frostnip. The symptoms of frostbite progress with prolonged exposure to cold. Historically, frostbite has been classified by degrees according to skin and sensation changes, similar to burn classifications. However, the degrees do not correspond to the amount of long term damage. A simplification of this system of classification is superficial (first or second degree) or deep injury (third or fourth degree).
