This comparative study of low doses of ropivacaine was conducted in order to identify the most effective form of analgesia during labour with the aid of supplementary low doses of fentanyl and clonidine. 60 ASA I and II parturient primipares who had asked for epidural analgesia were randomly assigned to two groups. Group R was given 5-7 ml 0.2% ropivacaine and Group B 0.125% bupivacaine with both groups receiving 75 ng clonidine and 50 ng fentanyl with their first bolus of local anaesthetic. The parameters measured included the speed and spread of the sensory blockade and the scale of any motor blockade. The material haemodynamics and VAS pain relief scores were also measured at 30-minute intervals during labour and all side-effects (nausea, vomiting, localised or generalised itching, headache etc) were also monitored. Apgar anaesthetics and other drugs was decided on the basis of the VAS score (a further dose was given to women with a VAS of > 3-4). The study was completed by a telephone interview 6 months after delivery and the data were analysed using the Student's t-test and the chi 2 test. The analgesic effect was satisfactory in both groups and no statistically significant differences were found between the two groups under most of the headings analysed, apart from the top-up doses needed to maintain adequate analgesia. The average time between the first VAS to parturition was 292 mns in Group B and 267 mns in Groups R. Top-up doses of local anaesthetic (2.35 vs 5.05) came on average to 15.8 ml in Group B compared to 24.1 ml in Group R. There were 20% Caesarian sections in Group R and 13.8% in Group B. Optimum analgesia was achieved in Group R, the level of analgesia was insufficient or barely sufficient in 3.3% of cases. There was no Apgar score < 7 in either group. It was therefore concluded that both bupivacaine and ropivacaine offer excellent analgesia during labour and have no significant side effects on mothers or babies.

Despite limited understanding of therapeutic aetiopathogenesis of ulcerative colitis and Crohn's disease, there is a strong evidence base for the efficacy of pharmacological and biological therapies. It is equally important to recognise toxicity of the medical armamentarium for inflammatory bowel disease (IBD). Sulfasalazine consists of sulfapyridine linked to 5-aminosalicylic acid (5-ASA) via an azo bond. Common adverse effects related to sulfapyridine 'intolerance' include headache, nausea, anorexia, and malaise. Other allergic or toxic adverse effects include fever, rash, haemolytic anaemia, hepatitis, pancreatitis, paradoxical worsening of colitis, and reversible sperm abnormalities. The newer 5-ASA agents were developed to deliver the active ingredient of sulfasalazine while minimising adverse effects. Adverse effects are infrequent but may include nausea, dyspepsia and headache. Olsalazine may cause a secretory diarrhoea. Uncommon hypersensitivity reactions, including worsening of colitis, pancreatitis, pericarditis and nephritis, have also been reported. Corticosteroids are commonly prescribed for treatment of moderate to severe IBD. Despite short term efficacy, corticosteroids have numerous adverse effects that preclude their long term use. Adverse effects include acne, fluid retention, fat redistribution, hypertension, hyperglycaemia, psycho-neurological disturbances, cataracts, adrenal suppression, growth failure in children, and osteonecrosis. Newer corticosteroid preparations offer potential for targeted therapy and less corticosteroid-related adverse effects. Azathioprine and mercaptopurine are associated with pancreatitis in 3 to 15% of patients that resolves upon drug cessation. Bone marrow suppression is dose related and may be delayed. The adverse effects of methotrexate include nausea, leucopenia and, rarely, hypersensitivity pneumonia or hepatic fibrosis. Common adverse effects of cyclosporin include nephrotoxicity, hypertension, headache, gingival hyperplasia, hyperkalaemia, paresthesias, and tremors. These adverse effects usually abate with dose reduction or cessation of therapy. Seizures and opportunistic infections have also been reported. Antibacterials are commonly employed as primary therapy for Crohn's disease. Common adverse effects of metronidazole include nausea and a metallic taste. Peripheral neuropathy can occur with prolonged administration. Ciprofloxacin and other antibacterials may be beneficial in those intolerant to metronidazole. Newer immunosuppressive agents previously reserved for transplant recipients are under investigation for IBD. Tacrolimus has an adverse effect profile similar to cyclosporin, and may cause renal insufficiency. Mycophenolate mofetil, a purine synthesis inhibitor, has primarily gastrointestinal adverse effects. Biological agents targeting specific sites in the immunoinflammatory cascade are now available to treat IBD. Infliximab, a chimeric antibody targeting tumour necrosis factor-or has been well tolerated in clinical trials and early postmarketing experience. Additional trials are needed to assess long term adverse effects.

The alpha-adrenergic agonists have been demonstrated to have synergistic effects with opioids and local anesthetics in animal research. The present study was performed to determine whether the addition of adrenaline improves the analgesic effects of an epidural infusion of a combination of fentanyl and bupivacaine after abdominal surgery. We studied 90 ASA 1 or 2 patients scheduled for abdominal surgery under epidural anaesthesia, with or without general anaesthesia. Patients were randomly divided into two groups to receive a postoperative epidural infusion of fentanyl 5 micrograms/ml in bupivacaine 0.2%, with or without adrenaline 5 micrograms/ml, at a rate of 2 ml/h for more than 48 hours. Postoperative pain relief was assessed using visual analog scales (VAS), both at rest and during coughing, at 2, 24, and 48 hours after surgery. The number of rescue analgesics and side-effects such as nausea, vomiting, pruritus, respiratory depression, headache, muscle weakness, and hypotension were recorded. Patients who received adrenaline (n = 40) reported significantly lower mean VAS scores than those who received no adrenaline (n = 37), both at rest at 24 hours postoperatively and during coughing at 24 and 48 hours. The number of additional analgesics and incidence of side-effects did not differ between groups. In conclusion, the results of the present study demonstrate that the addition of adrenaline to a combination of fentanyl and bupivacaine improves the quality of epidural analgesia after abdominal surgery. Under the conditions of the study, we did not detect any disadvantage from the addition of adrenaline.

This study was a multinational, multicentre, double-blind, active controlled phase III trial designed to investigate efficacy and safety of 300 mg acetylsalicyclic acid (ASA) (n = 135) vs. 200 mg metoprolol (n = 135) in the prophylaxis of migraine. In total 270 (51 male and 219 female) patients, aged 18-65 years, suffering between two and six migraine attacks per month were recruited. The main objective was to show equivalence with respect to efficacy, defined as a 50% reduction in the rate of migraine attacks. A run-in phase was carried out with placebo for 4 weeks, followed by a 16-week drug phase. In both treatment groups the median frequency of migraine attacks improved during the study period, from three to two in the ASA group and from three to one in the metoprolol group; 45.2% of all metoprolol patients were responders compared with 29.6% with ASA. Medication-related adverse events were less frequent in the ASA group (37) than in the metoprolol group (73). The findings from this trial show that metoprolol is superior to ASA for migraine prophylaxis but has more side-effects. Acetylsalicylic acid is better tolerated than metoprolol. Using a strict responder criterion ASA showed a responder rate comparable with the placebo rate in the literature.

Sixty ASA Grade II-III patients, without clinical symptoms of ventricular dysfunction and scheduled for elective bifemoral grafting for abdominal aneurysms, were allocated randomly to three equal groups to receive 150 micrograms sufentanil intravenously, epidurally or intrathecally. All patients received midazolam, vecuronium and nitrous oxide. Except for right ventricular stroke work index and pulmonary vascular resistance, all haemodynamic measurements decreased after sufentanil injection, but to the greatest extent after intravenous injection. Response to abdominal incision reversed the haemodynamic changes, although this was not accompanied by an increase in heart rate and coronary perfusion pressure after intrathecal injection. Four patients given intravenous, and four patients given epidural sufentanil required additional sufentanil after abdominal incision. Despite the changes in systemic vascular resistance and the concordant alterations in cardiac index after aortic cross-clamping and revascularization, intrathecal sufentanil provided more stability in heart rate than intravenous or epidural sufentanil. In conclusion, intrathecal sufentanil produced the most stable heart rate. Two patients in the intrathecal group developed spinal headaches post-operatively.

Susac's syndrome is an extremely rare clinical manifestation characterized by the triad of fluctuating sensorineural hearing loss, sudden visual loss and encephalopathy. Probably underdiagnosed, it affects young women who start the clinical history with headache, visual and hearing disturbances, with neurological findings in MRI. With unknown aetiology, pathogenesis is based on arteriolar microinfarcts in retina, cochlea, and grey and white matter in the brain. Treatment is, as stated in the bibliography and our experience, intravenous high doses of steroids followed by oral steroids together with hyperbaric oxygen to minimize ischaemic lesions. Aspirin associate to nimodipine has been useful to date in the treatment of our patient. We present a case and review the existing literature.

Patients' and caregivers' fear of addiction to and concern about side effects of morphine have been found to be among the major barriers to adequate pain relief in cancer patients. In contrast, the transdermal administration of opioids by means of fentanyl patches does not seem to evoke such fears. In a qualitative study, 60 patients in our outpatient pain clinic recorded up to five associations with a list of diseases, drugs and administration routes. Cancer and AIDS were associated most often with death, followed by suffering, anxiety and hopelessness. Migraine was associated predominantly with pain and other physical symptoms. Aspirin was associated less with pain in general than with headache and, sometimes, specifically with alcohol or hangover. Morphine was associated predominantly with pain and pain relief, but fears of intoxication, abuse and addiction and concerns about side effects were frequently named. Major differences were evident from the associations with the different routes of administration. The word 'pill' was mostly associated with contraception. Associations with 'tablets' were more pharmacological in nature, and side effects were frequently named. Patches were associated with wounds, cuts, bruises, and blisters and with protection. Some associations with patches were related to comfort. Injections and infusions were associated with physicians or the hospital environment. In conclusion, patients expressed major differences in their perceptions of the different drugs and routes of administration. The results may give a first hint that minor cultural differences even between western European countries may lead to major differences in prescribing habits and treatment regimens.

The study was designed to investigate the effects of simultaneously combined spinal-epidural anaesthesia in elderly patients and to evaluate the problems encountered during and after performing spinal block following epidural blockade. Nineteen ASA grade III elderly patients (mean age 75.8 years) were included in the study. The first 10 patients (group 1) were given 0.5% hyperbaric bupivacaine 2 ml (10 mg) and fentanyl 0.25 ml (12.5 microg) intrathecally. The remaining nine patients (group 2) received 0.5% hyperbaric bupivacaine 1 ml (5 mg) intrathecally; following the spinal block fixation (about 15 min), fentanyl 1 ml (50 microg) in saline 10 ml was injected into the epidural catheter. The highest sensory block was achieved at T6 and T9 in groups 1 and 2, respectively. None of the patients experienced respiratory depression, sedation, vomiting, shivering or headache. In conclusion, simultaneous combination of subarachnoid and epidural blockade may provide sufficient anaesthesia with fewer complications.

Most people with episodic tension-type headache (TTH) treat themselves with over-the-counter analgesics. In the absence of clear evidence of dose-related efficacy of the two most commonly used analgesics, aspirin (acetylsalicylic acid) and paracetamol (acetaminophen), this study compared two doses of each with placebo. In a double-blind, double-dummy, randomized parallel-groups comparative trial, 638 consenting subjects aged 16-65 years with episodic TTH (but not migraine) by IHS criteria were recruited from the UK general population by advertisement. They treated one episode of moderate or severe TTH with a single dose of 500 or 1000 mg aspirin, 500 or 1000 mg paracetamol or placebo. The primary objective was to compare aspirin 1000 mg with placebo, and the primary end-point was subjective pain relief (total or worthwhile) 2 h after treatment ('response'). Additionally, pain intensity on a 100-mm visual analogue scale and functional impairment were monitored regularly for 4 h and at 24 h, although rescue medication was allowed after 2 h. The analysis was of the intention-to-treat population of 542 who took treatment (all providing outcome data). Treatment groups were matched at baseline. Aspirin 1000 mg (75.7% response rate; P = 0.0009) and to a lesser extent aspirin 500 mg (70.3%; P = 0.011) and paracetamol 1000 mg (71.2%; P = 0.007), but not paracetamol 500 mg (63.8%; P = 0.104), were statistically more effective than placebo despite a high placebo-response rate (54.5%). Outcome was not affected by headache intensity at baseline. Secondary end-points including functional recovery (by median times of 4.0-13.5 h) were consistent with these findings, although a minority of subjects recorded long-duration functional impairment (37-54 h). Adverse events reported by 13.4-18.9% of subjects were mild or moderate, and transient. No safety concerns arose.

Low-dose ibuprofen is as effective as aspirin and paracetamol for the indications normally treated with over-the-counter (OTC) medications and is associated with the lowest risk of gastrointestinal toxicity of any non-steroidal anti-inflammatory drug. By contrast, even low-dose aspirin is associated with an appreciable risk of gastrointestinal toxicity. Paracetamol is well tolerated and effective in treating mild to moderate pain but there is growing concern about a possible risk of gastrointestinal toxicity and a possible link with asthma in children. The PAIN (Paracetamol, Aspirin, Ibuprofen New tolerability) study was a blinded randomised comparison of the tolerability of OTC analgesics in the treatment of common types of acute pain encountered in the community. A total of 8,677 adults were randomised to treatment with ibuprofen 1200 mg/day, paracetamol 3 g/day or aspirin 3 g/day for 1-7 days. The most common indications for treatment were musculoskeletal conditions (31-33%), colds or flu (19-20%), backache (15-17%), sore throat (11-12%) and headache (10-11%). Significant adverse events were more common with aspirin (10.1%) than ibuprofen (7.0%) (P<0.001) or paracetamol (7.8%). Significant gastrointestinal events were less frequent with ibuprofen (4.0%) than with aspirin (7.1%, P<0.001) or paracetamol (5.3%) (P=0.025). For every 100 patients treated, five more will experience significant adverse events if they are taking aspirin rather than ibuprofen, and four more than if they were taking paracetamol.
