From August 1981 to May 1993 a total of 1263 percutaneous retrogasserian glycerol rhizotomies after Hakanson were performed. The intervention was performed with X-ray monitoring under local anaesthesia and rarely lasted longer than 20 min. It achieved good results in the treatment of idiopathic trigeminal neuralgia (TN) and symptomatic trigeminal neuralgia due to multiple sclerosis (TNMS). ⋯ Later, after 2 years, there was reduction in sensitivity of this type in only 20% of cases. In the follow-up 17.5% of our patients complained of dysaesthesia and in 21.4% corneal sensitivity was reduced or lost. We believe that glycerol rhizotomy, owing to its effectiveness, easy applicability, slight distress for the patients and low side effects, should be recommended as a first measure for non-conservative treatment of idiopathic trigeminal neuralgia as well as trigeminal neuralgia in multiple sclerosis.

In 1986 the World Health Organisation (WHO) proposed an analgesic ladder for the effective therapy of cancer pain. The three standard analgesics making up this ladder are aspirin (non-opioid), codeine (weak opioid) and morphine (strong opioid). Adjuvant drugs may be added at any level. However, before 1986 step II analgesics (weak opioids) had never been tested in cancer pain relief. ⋯ The use of the WHO guidelines "by mouth, by the clock and by the ladder" is now the mainstay of cancer pain management. Because of the guidelines' simplicity they found general acceptance and helped to establish an international pain therapy standard for worldwide use. Nevertheless, there is no scientific validation of WHO step II. In the absence of prospective controlled randomized trials additional longterm results are necessary. We need more data on the use of WHO step II and an update of the published guidelines taking account of modern sustained-release drugs. Up to now, step II of the WHO guidelines for cancer pain is not a clinical reality but at best a didactic instrument.

A 21-year-old man suffered from diffuse low back pain and sciatica for 10-s periods once or twice a day over a period of 6 months. After this, pain became chronic and was resistant to conventional conservative treatment. Only acetylsalicylic acid diminished pain. ⋯ The time between onset of symptoms and final diagnosis was 18 months. Symptoms disappeared after surgery. Clinical and radiological aspects of the case are discussed.

This is the first case report of a patient self-administering local anaesthetics to painful peripheral nerves in the face. Severe chronic pain of neuropathic origin was caused by a trauma of the face and head following a traffic accident 20 years ago. The patient himself chose the method of self-injection for pain control. He applies the local anaesthetic bupivacaine with an insulin syringe while looking in a mirror.
