Background. When using the combined spinal-epidural CSE ; technique for labour analgesia, parturients often experience breakthrough pain after the spinal medication has receded. We tested the hypothesis that a small dose of intrathecal morphine would reduce breakthrough pain. Methods. This was a randomized, double-blind, placebo-controlled trial. Subjects were randomized to receive either 100 mg of morphine MS ; or placebo PLCB ; with the spinal injection of bupivacaine and fentanyl. Assessments included need for supplementation during labour analgesia, use of pain medications for 24 h after delivery, and side-effects. The primary endpoint was the rate of breakthrough pain. Results. Sixty subjects were enrolled, 55 subjects completed the trial. The MS group had a significantly lower rate of breakthrough pain than the PLCB group [0.6 0.6 ; vs 1.1 0.8 ; episodes per patient; P, 0.01], and longer time to first episode of breakthrough pain 300 vs 180 min; P0.03 ; . The MS group used 75% less opioid medications during the subsequent 24 h, but had a 17% incidence of nausea. Conclusions. The addition of small dose of morphine to the spinal component of the CSE technique improved the effectiveness of epidural labour analgesia and reduced the need for pain medications over 24 h, but resulted in a small increase in nausea.

The cause of CLL is not yet known. Some studies of large series of CLL patients demonstrated that in CLL cells of about half of the cases the IgVH genes have undergone somatic mutations [152, 153] and the unmutated cases were correlated to a worse clinical outcome [154, 155]. The presence of somatic mutations suggests that, at least in the mutated patients, CLL clonal founder cells had encountered an Ag and that the procedure triggered by this encounter had likely occurred in a germinal center GC ; site [143, 156]. However, based on other evidences the unmutated cases could not be considered naive B-cell driven and are similar to mutated ones, except for IgVH. Although slightly different, both subsets of CLL cells show a remarkable skewing in IgVH genes usage such as the overexpression of IgVH 1-69 and IgVH 321[152, 153, 155]. This bias appears to be disease related, therefore suggesting a role for specific Ag or Ag-like elements in the genesis of this subset of CLL [143]. In addition, both CLL subsets have surface phenotype of activated B cells similar to the phenotype of Ag-experienced cells CD23, CD25, CD69, and CD79 ; [157]. The characteristics of CLL cells' BCR look like those observed in normal B cells upon Ag interaction [158, 159]. Finally, gene expression profiling revealed that both mutated and unmutated subsets share similarities with memory B cells [160, 161]. From all of these evidences this impression has arisen that in CLL, regardless of the IgVH genes mutational status, the cell of origin appears to be an "Ag-experienced" B cell [143]. It.

PEEP is a mode of therapy which is used in conjunction with mechanical ventilation whenever in spite of administeration of 100 percent oxygen, there is still inadequate oxygenation 10 ; . Mechanical ventilation with PEEP is a welldocumented cause of reduction in cardiac output, renal flow, glomerular filtration rate and urine flow 12-14 ; . Also, it has been shown that PEEP is associated with decrease in hepatic and or portal blood flow as well 15-17 ; . Therefore, it has been theorized that the pharmacokinetics of drugs that are predominantly eliminated through the liver might be substantially affected following positive ventilatory supports measures 18 ; . While alteration in pharmacokinetic parameters of some drugs such as lidocaine 19 ; , amikacin 20 ; and aminophylline 21 ; by PEEP have been reported, the contribution of mechanical ventilation in alteration of phenytoin clearance is unknown and has not yet been quantified. On the other hand, in vitro studies on oxidatively metabolized drugs such as propranolol and theophylline have shown that hypoxic conditions Even by relatively minor reductions in oxygen supply, of a magnitude likely to be encountered in vivo ; and oxygen supplementation may result in impairement or restoration of oxidative metabolism of these drugs, respectively 22-24 ; . Beacause phenytoin elimination performs almost entirely through hepatic oxidation by cytochrome P450 CYP ; 2C9 and CYP2C19 as principle enzymes ; , it is expected that the hepatic oxidative metabolism of phenytoin should be influenced by alteration in oxygenation or conditions that alter hepatic oxygenation. This may be of special attention in regard to PEEP beacause while its use improves oxygenation and treates acute pulmonary failure, it may contribute to mesenteric ischemia due to alteration in regional blood flow. Phenytoin has a relatively narrow therapeutic range of serum concentrations, 40-80 mol l 1020 mg l ; , and is known to show concentrationdependent kinetics within this therapeutic range. Because of the fact that, small changes in dose and minor alterations in hepatic metabolism of phenytoin may cause a disproportionately large effect on serum concentrations, in this study it was intended to examine whether the application of PEEP in levels usually used for brain injured patients could have influences on the pharmacokinetic profile of phenytoin in these patients? and if so, will there be a need for dosing adjustment in this setting? METHODS The study was conducted at trauma neurosurgical ICU of Sina Hospital. Fifteen male or nonpregnant female patients aged 18 or older who.

Of activity, with 25 of 31 strains susceptible to 32 , ug ml. All the test antimicrobial agents were highly active against E. coli. Ceftazidime was again highly active against K. pneumoniae, with 7 of 7 strains susceptible to 0.5 p g ml, whereas 7 of 7 strains were susceptible to 4 , ug amikacin per ml. Ticarcillin, as expected, was not very active against K. pneumoniae. Two of the randomly selected strains of S. aureus were later found to be methicillin resistant. Consequently, all three test antimicrobial agents showed rather poorly against S. aureus. Nevertheless, the five methicillinsusceptible strains were susceptible to 8 , ug less of both ceftazidime and ticarcillin with the standard inoculum. Amikacin was also active, with 5 of 5 methicillin-susceptible strains susceptible to 2 , ug and the methicillin-resistant strains susceptible to 16 , ug ml. Serum bactericidal activity. The geometric mean serum bactericldal titers for both regimens at both 1 and 6 h are displayed in Table 2. The geometric mean bactericidal titers of ceftazidime were significantly better than those obtained with ticarcillin plus amikacin at both 1 and 6 h for each species of gram-negative bacilli. Against the 31 strains of P. aeruginosa, ceftazidime produced a geometric mean bactericidal titer of 1: 40.7 after 1 h of antibiotic administration, which was over three times that generated by the combination of ticarcillin plus amikacin 1: 12.2 ; . At 6 h, the bactericidal titer of ceftazidime was still greater than twice that generated by the combination. Against E. coli and K. pneumoniae, ceftazidime showed uniformly good serum bactericidal activity at both 1 and 6 h, the lowest mean titer being 1: 97 at against K. pneumoniae. Ticarcillin plus amikacin also performed quite well against these organisms. A geometric mean bactericidal titer of 1: 125 at 1 h and 1: 8 at was obtained against E. coli, and for K. pneumoniae a geometric mean titer of 1: 86 was obtained at 1 h, declining to 1: 8 Against S. aureus, ceftazidime performed poorly, with a geometric mean of 1: 3.6 at 1 h, and failed to produce measurable bactericidal activity at 6 h. However, when the methicillin-resistant strains are removed from consideration, the geometric mean bactericidal titer at 1 h was 1: 5.5 for ceftazidime, but no bactericidal activity was produced at 6 h. Ticarcillin plus amikacin was significantly better against this bacterium, with a mean titer of 1: 24 declining to 1: 3 The cumulative percentage of determinations bactericidal.

93 MECHANISMS OF ACTION OF THE V.A.C. DEVICE IN THE DB DB MOUSE MODEL Sandra Saja Scherer MD1, Giorgio Pietramaggiori MD1, 2, Jasmine C. Mathews BA1, Dennis P Orgill MD PhD1 1Division of Plastic Surgery, Brigham and Women's Hospital, Harvard Medical School, 2Division of Plastic Surgery, University of Padua, Italy The vacuum assisted closure device V.A.C ; has been used as a wound healing tool for several years. However, its mechanism of action is still poorly understood. We fragmented the V.A.C. device into its single elements and studied the impact of each on healing in the diabetic mice. Full thickness skin wounds on the dorsum of db db mice were treated for 7 days with the V.A.C. device or its single components polyurethane sponge, sub-atmospheric pressure, or occlusive dressing alone ; . In addition, we studied the effects of V.A.C. application for 12 hours and followed up for a total of 7 days. Dressings were changed every 48 hours and standardized digital pictures were taken on days 0, 2, 4 and 7. Then, wounds were harvested. Histological cross sections were stained for H&E, PECAM-1 and Ki67 to quantify granulation tissue area, vascularization, and cell proliferation, respectively. Wounds treated with the sponge showed less contraction compared to all other groups. The 12-hour V.A.C. treatment showed faster wound closure starting from day 4 compared to wounds treated with the V.A.C. device for 7 days continuously. 12-hour V.A.C. treatment increased granulation tissue formation compared to the other groups except the V.A.C. applied for 7 days. The V.A.C. treatment, both for 7 days and 12 hours, induced dramatic increases in cell proliferation compared to all other groups. No differences were seen in microvessel density among the groups. The V.A.C. device enhances healing mainly through increased cell proliferation. The effects of the composite device are superior to the effects of its single elements. These effects might be a cause of an early trigger rather than by continuous stimulation. Mechanical forces and the reduction of the wound fluid may be important in the mechanism of action of the V.A.C. device and amikacin.
