Randomized Controlled Trial Clinical Trial
Comparison of central venous catheterization sites in infants.
This study aimed to compare the rates of success and complications between different sites of central venous catheterization in infants. A total of 272 infants were randomized to four groups: right subclavian group (G-RSCV), right internal jugular group (G-RIJV), left subclavian group (G-LSCV) and left internal jugular vein group (G-LIJV). ⋯ With regard to complications, the rate of arterial puncture, guide wire advancement failure and malpositioning of the catheter were all significantly more frequent during SCV catheterization (SCV versus IJV: 10.1% versus 2.1%, 12.4% versus 0% and 13.4% versus 0.6%, respectively). Our results imply that IJV, especially RIJV, should be the first choice for central venous catheterization in infants.

We aimed to evaluate retrospectively the clinical and bacteriological efficacy and potential side-effects of teicoplanin treatment in neonates with proven staphylococcal infection. There were 37 episodes of staphylococcal septicaemia in neonates with a mean gestational age of 34.2 +/- 2.3 weeks; 26 were caused by coagulase-negative staphylococcal (CoNS) sepsis and 11 by Staphylococcus aureus sepsis. All episodes were treated with teicoplanin (intravenous loading dose 16 mg/kg followed by a maintenance dose of 8 mg/kg daily). ⋯ The mean duration of treatment of the survivors was 11.6 +/- 2.3 days. There were no drug-related adverse events and the biochemical and haematological tests showed no clinically significant changes in relation to teicoplanin therapy. Our results suggest that teicoplanin is highly effective in neonatal staphylococcal sepsis.

We investigated the effects of intra-articular injections of bupivacaine and neostigmine on articular cartilage and the synovial membrane of rabbit knee joints. Saline, bupivacaine or neostigmine were each administered intra-articularly into 15 knee joints. Five joints per drug treatment were prepared for histopathological examination 24 h, 48 h and 10 days after injection. ⋯ Joints treated with bupivacaine and neostigmine showed significantly more histopathological changes than control joints. Joints treated with neostigmine showed significantly more histopathological changes than those treated with bupivacaine, except for articular cartilage inflammation on day 10. We conclude that intra-articular bupivacaine and neostigmine cause histopathological changes in rabbit knee joints, with neostigmine having a greater effect than bupivacaine.

We investigated the effects of melatonin administration on skeletal muscle ischaemia-reperfusion injury (IRI) by assessing plasma malondialdehyde (MDA), superoxide dismutase (SOD), total glutathione (GSSH), glutathione peroxidase (GPX) and myeloperoxidase (MPO) concentrations. Male Sprague-Dawley rats (n = 32) were randomized into four groups: group 1 served as time controls; group 2 were the test animals; group 3 received melatonin (30 mg/kg) intraperitoneally prior to the induction of ischaemia; and group 4 received melatonin (30 mg/kg) intraperitoneally prior to the reperfusion period. ⋯ Ischaemia-reperfusion injury significantly increased activities of GPX, SOD and MPO, and melatonin administration reversed this effect. In conclusion, a pharmacological dose of melatonin showed significant protective effects against IRI by decreasing lipid peroxidation, MPO, SOD and GPX enzyme activities and regulating glutathione content.

Randomized Controlled Trial Clinical Trial
Effectiveness of hyperbaric oxygen therapy in the treatment of complex regional pain syndrome.
In this double-blind, randomized, placebo-controlled study we aimed to assess the effectiveness of hyperbaric oxygen (HBO) therapy for treating patients with complex regional pain syndrome (CRPS). Of the 71 patients, 37 were allocated to the HBO group and 34 to the control (normal air) group. Both groups received 15 therapy sessions in a hyperbaric chamber. ⋯ In the HBO group there was a significant decrease in pain and oedema and a significant increase in the ROM of the wrist. When we compared the two groups, the HBO group had significantly better results with the exception of wrist extension. In conclusion, HBO is an effective and well-tolerated method for decreasing pain and oedema and increasing the ROM in patients with CRPS.
