Abstract
2526 Background: Use of concomitant medications that inhibit drug metabolizing enzymes such as Cyp3A4 is common and may affect chemotherapy PK/PD. We studied the effects of Cyp3A4 inhibition with ketoconazole on docetaxel PK/PD in 3 Asian ethnic groups. Methods: Two cohorts of chemonaive breast cancer patients were compared. The first cohort comprised of 95 patients (62 Chinese, 26 Malay, 7 Indian) treated with 75mg/m2 docetaxel unmodulated by ketoconazole, while the second cohort comprised of 31 patients (14 Chinese, 14 Malay, 3 Indian) treated with docetaxel 70mg flat dose modulated by oral ketoconazole, a regimen we previously reported to result in comparable docetaxel AUC as 75mg/m2 docetaxel. Plasma docetaxel concentrations were obtained at 0, 0.5, 1, 2, 5, 7 and 24 hours, and blood counts monitored on days 8 and 15 of cycle 1. Results: No significant differences in docetaxel PK or neutropenia between the races were observed in response to 75mg/m2 docetaxel unmodulated by ketoconazole (docetaxel clearance 36.4±16.9, 34.3±12.5, 44.2±27.7L/h, p=0.702; docetaxel AUC 3.6±2.7, 3.5±1.2, 2.9±1.3mg/L h, p=0.418; day 8 neutrophil count 0.5±0.6, 0.8±0.8, 0.4±0.3x109/L, p=0.138; grade 4 neutropenia 66%, 50%, 86%, p=0.157). In contrast, when docetaxel was administered with ketoconazole to inhibit Cyp3A4, inter-ethnic differences in docetaxel PK/PD were observed, with Chinese having the lowest docetaxel clearance and highest docetaxel AUC, followed by Malays and Indians (docetaxel clearance 18.6±5.7, 23.7±9.3, 30.6±6.7L/h, p=0.048; p=0.017 trend test; docetaxel AUC 4.2±1.4, 4.1±3.9, 2.4±0.5 mg/L h, p=0.048, p=0.017 trend test), although there were no statistically significant differences in body weight or surface area between the races. In concordance, Chinese patients experienced greatest degree of myelosuppression, followed by Malays and Indians (day 8 neutrophil count 0.8±0.8, 1.5±1.1, 1.7±1.1x109/L, p=0.046, p=0.013 trend test), and were more likely to develop grade 4 neutropenia (57%, 14%, 0%, p=0.024) from docetaxel + ketoconazole. Conclusions: Inter-ethnic differences in CYP3A inhibition by ketoconazole exist, and are important when evaluating the impact of concomitant medications with chemotherapy that may inhibit Cyp3A4. No significant financial relationships to disclose.

Abstract
With advances in technology, videoscopy and optic intubation have been gaining popularity particularly in patients with difficult airways or as rescue devices in failed intubation attempts. Their routine use is, however an uncommon occurrence. This review paper will summarise some of those newly developed devices currently available to assist tracheal intubation, their advantages, disadvantages when compared with the conventional laryngoscope and finally, evidence to support their use in both elective and emergency airway management.

Abstract
Identification of the epidural space is often performed using the loss of resistance technique to either air or saline. We sought to investigate if the medium used affected the quality of analgesia obtained by parturients who received labour epidurals. We conducted a retrospective audit of labour epidurals performed on nulliparous parturients in our institution from May 2003 to March 2005. All epidural catheters were inserted by senior obstetric anaesthetists using a combined spinal epidural technique. The following information was recorded: parturients' demographic data, loss of resistance technique used, type and amount of local anaesthetic solution administered, complications encountered during procedure, pre-block and post-block pain scores, incidence of breakthrough pain requiring supplemental medication and post-block side-effects. Data from 2848 patients were collected and analysed; 56% of patients made up the saline group and 44% the air group. Patients in both groups had similar demographic profiles and similar incidences of complications and post-block side-effects. However patients in the air group had a higher incidence of recurrent breakthrough pain P = 0.023). We also identified three other factors that were associated with an increased incidence of recurrent breakthrough pain; administration of pre-block oxytocin, sitting position of the parturient during the procedure and the use of intrathecal bupivacaine for induction of analgesia. Our findings suggest that a loss of resistance to air is associated with a higher incidence of recurrent breakthrough pain among parturients who received combined spinal epidural analgesia for labour than a loss of resistance to saline.

Abstract
We report a case of palatopharyngeal wall perforation during intubation with a GlideScope® laryngoscope. The likely mechanism was advancing and rotating the endotracheal tube against a taut palatopharyngeal fold. This was missed during the initial laryngoscopy, because there is a potential blind-spot in the oropharynx when attention is focused on the GlideScope® monitor. Fortunately, there were no sequelae other than minor bleeding and a mild sore throat and no surgical intervention was necessary. The use of unnecessary force during the endotracheal tube insertion, the use of too large a laryngoscope blade and the use of a rigid stylet could possibly also have been contributory factors to this complication.

Abstract
Signals from fibronectin-binding integrins promote neural crest cell motility during development in part through protein-tyrosine kinase (PTK) activation. Neuroblastoma (NB) is a neural crest malignancy with high metastatic potential. We find that alpha4 and alpha5 integrins are present in late-stage NB tumors and cell lines derived thereof. To determine the signaling connections promoting either alpha4beta1- or alpha5beta1-initiated NB cell motility, pharmacological, dominant negative and short-hairpin RNA (shRNA) inhibitory approaches were undertaken. shRNA knockdown revealed that alpha5beta1-stimulated NB motility is dependent upon focal adhesion kinase (FAK) PTK, Src PTK and p130Cas adapter protein expression. Cell reconstitution showed that FAK catalytic activity is required for alpha5beta1-stimulated Src activation in part through direct FAK phosphorylation of Src at Tyr-418. Alternatively, alpha4beta1-stimulated NB cell motility is dependent upon Src and p130Cas but FAK is not essential. Catalytically inactive receptor protein-tyrosine phosphatase-alpha overexpression inhibited alpha4beta1-stimulated NB motility and Src activation consistent with alpha4-regulated Src activity occurring through Src Tyr-529 dephosphorylation. In alpha4 shRNA-expressing NB cells, alpha4beta1-stimulated Src activation and NB cell motility were rescued by wild type but not cytoplasmic domain-truncated alpha4 re-expression. These studies, supported by results using reconstituted fibroblasts, reveal that alpha4beta1-mediated Src activation is mechanistically distinct from FAK-mediated Src activation during alpha5beta1-mediated NB migration and support the evaluation of inhibitors to alpha4, Src and FAK in the control of NB tumor progression.
