In order to investigate the efficacy and safety of long-term treatment with flupirtine in patients with chronic pain, in particular arthrosis and arthritis, a study was planned which, when completed, will encompass the treatment of 200 patients over a 12-month period. The present paper is a preliminary report of this ongoing study. The report deals with 104 patients: 55 of whom completed the 12-month treatment period and a 2-week follow-up phase, during which flupirtine was replaced by placebo in order to be able to detect drug-withdrawal effects. ⋯ If the withdrawal phenomena had corresponded to the flupirtine's terminal half-life, then the symptoms ought to have been present mainly in the first few days. There was a slight trend for lowering systolic blood pressure but no changes in diastolic blood pressure or heart rate, nor changes in the ECG or laboratory analysis that could be related to flupirtine. These preliminary data suggest that flupirtine is safe when given for a period of one year.

To assess the role of stapling devices and routine gastroenterostomy in palliative bypass surgery, the hospital records of 150 consecutive patients with unresectable, histologically proven pancreatic adenocarcinoma requiring palliative bypass procedure were reviewed. During recent years staplers have gained increasing acceptance for construction of palliative anastomoses. Mortality and morbidity were lower after stapled anastomoses. ⋯ Delayed gastric emptying occurred, however, in 10% and significant upper gastrointestinal bleeding in 7% of the patients after prophylactic gastroenterostomy. We conclude that stapling devices are safe and practical in palliative bypass surgery and they significantly reduce operation time if more than one bypass is required. The relatively high incidence of delayed gastric emptying, and significant upper gastrointestinal bleeding after prophylactic gastroenterostomy and the infrequent occurrence of gastric outlet obstruction after initial biliary bypass together with the low mortality after reoperation, suggest that gastroenterostomy should be performed on a selective basis only.

The pituitary as a target of antalgic treatment of chronic cancer pain: a possible mechanism of pain relief through pituitary neuroadenolysis.
Surgical hypophysectomy performed in 18 cases with hormone-dependent carcinoma resulted in tumour regression in 38.8% of the cases, and pain relief in 88%. Neuroadenolysis performed 170 times on 130 cases resulted in pain relief in 94% with hormone-dependent carcinoma, and 70% with non-dependent carcinoma. ⋯ Increase of beta-endorphin in CSF was very brief. Though the exact physiological activity in pain sensation of those peptides other than endorphins still remains obscure, increase of the peptides which are mainly synthesized in the hypothalamopituitary axis, along with suppressed pituitary function, is considered to exert a long-lasting suppressive effect on the mediation and perception of cancer pain through C-fibres and the central nervous system.
