The aim of the present study was to evaluate the efficacy of EMLA cream (containing a eutectic mixture of local anaesthetics) in controlling pain due to arteriovenous fistula cannulation in teenagers undergoing chronic haemodialysis. The study was conducted in two phases, one prospective, the other a blind randomized trial, at the Paediatric Haemodialysis service of the Paediatrics Department of Padua University, Italy. ⋯ Results showed that: (1) the visual analogue scale calls for an adequate training period; and (2) the EMLA cream might be effective in controlling cannulation-related pain but emotional factors, such as uncontrolled fear and stress, can interfere with the global efficacy of the analgesic approach.

Positive results of pilot studies of the effect of staphylococcus toxoid vaccine in patients with fibromyalgia and chronic fatigue syndrome were the incitement to the present, placebo-controlled study. It included 28 patients who fulfilled the criteria for both fibromyalgia and chronic fatigue syndrome. The effect of vaccination with a staphylococcus toxoid was compared with the effect of injections of sterile water. ⋯ Fifty percent were rehabilitated successfully and resumed half-time or full-time work. The results of this study support the authors>> hypothesis that treatment with staphylococcus toxoid may be a fruitful strategy in patients with fibromyalgia and chronic fatigue syndrome.

Temporal summation of pain is suggested to be an important factor during various clinical conditions. Controversies exist as to whether temporal summation exists for Adeltafibre-mediated first pain. The aim of the present human experimental study was to investigate the importance of stimulus configuration (intensity, inter-pulse interval, location) for temporal summation of radiant (laser)- and contact-heat-induced pain. ⋯ Taking the latency from stimulation to perception into consideration, we were able to differentiate and find summation of first (Adeltafibre-mediated) and second pain (C fibre-mediated). Summation of first pain was more pronounced for high (38 degrees C) than for low (30-32 degrees C) baseline temperature.

The aims of this study were: (1) to compare two groups of patients with chronic pain conditions (work-related muscular pain, mainly low back pain, and fibromyalgia) in general coping and pain-specific coping; (2) to examine the relationship between general and pain-specific coping and, (3) to examine the influence of state-trait anxiety on general and pain-specific coping. The sample included 80 individuals (range=19-70 years; mean=47; SD=9.9), who were patients at two pain management clinics for examination of their physical and psychosocial health conditions and consideration on disability pension. The patients were asked to respond to theStrategies to Handle Stress Questionnaire, theCoping Strategies Questionnaireand theState-Trait Anxiety Inventory. ⋯ Anxiety-prone patients with fibromyalgia might benefit from psychological support in the process of coping with pain.

The characteristics of chest pain due to suspected acute myocardial infarction and morphine use during the first 3 hospital days are described in a population of 2988 consecutive patients admitted to hospital. The duration of pain was usually less than 24 h (mean 20.9+/-0.55 h), and only 24.8% of patients experienced chest pain of longer duration. The majority of patients had only one attack of pain, but 34.4% experienced four or more attacks during hospitalization. ⋯ When intravenous morphine is given, it attains full effect 20 min after injection. Furthermore, the active morphine metabolites M3G and M6G appear rapidly in the circulation, which could influence the analgesic response to morphine treatment.
