Abstract
Indications for total pelvic exenteration in a male (removal of the bladder, prostate and rectum) and in a woman (removal bladder, uterus, vagina, ovaries and rectum) are rare. The advanced stage generally dictates that the patient has some form of chemotherapy or radiotherapy, or a combination of two to shrink/debulk the tumour. We report the first two cases of a salvage laparoscopic total pelvic exenteration in a male for rectal adenocarcinoma invading into the bladder and prostate, post-chemo-radiotherapy and in a woman for squamous cell carcinoma of cervix invading the bladder and rectum post-chemo-radiotherapy. Salvage surgery is often difficult and has been noted to have high morbidity. Applying a laparoscopic approach to this group may have advantages for the patient and the surgeon, i.e. less pain, early recovery and magnified views. As we have technically shown it to be possible, perhaps laparoscopic approaches should be discussed if the teams in these centres are of advanced laparoscopic surgeons working in multi-skilled groups.

Abstract
BACKGROUND Isoflurane has been shown to induce tolerance against ischaemic injury in adult rodents. Although the delayed preconditioning effect of isoflurane has been demonstrated in neonatal rat pups, the acute preconditioning effects of isoflurane remained undetermined. The present study was therefore conducted to evaluate the acute preconditioning efficacy of isoflurane in neonatal rats subjected to a hypoxic-ischaemic (HI) injury. METHODS Post-natal day 7 pups were exposed to 1 or 2% isoflurane in oxygen for either 30, 60 or 90 min. Fifteen minutes after isoflurane exposure, the pups were subjected to an HI injury induced by left common carotid artery ligation and exposure to 8% oxygen for 2 h. Pups not exposed to isoflurane or not subjected to HI served as controls. Histopathologic injury to the cortex and hippocampus was evaluated 7 and 49 days after HI. RESULTS Isoflurane 2% exposure for 60 or 90 min before HI induced tolerance in the hippocampus and the number of normal neurons in the CA1 sector 7 days after HI was significantly greater than in non-preconditioned animals. This protective efficacy of isoflurane preconditioning was not observed 49 days after HI. CONCLUSIONS Exposure of 2% isoflurane for at least 60 min is required to induce tolerance against HI injury in rat pups. However, this neuroprotective efficacy results in only transient neuroprotection.

Abstract
We currently present a design concept for a photoacoustic imaging endoscope as well as some preliminary experimental results. The device is based on the generation of acoustic waves in tissue by short laser pulses and the sensing of these waves with a thin, optical Fabry-Pérot etalon. The entire device is designed to be mounted on the tip of a needle to deliver high-resolution photoacoustic imaging for minimally-invasive clinical applications such as diagnosing kidney disease and guiding laparoscopic surgery.

Abstract
Cell-cell adhesion is a critical property of all multi-cellular organisms and its correct regulation is critical during development, differentiation, tissue building and maintenance, and many immune responses. The multi-talin-like FERM domain containing protein, FrmA, is required during starvation-induced multi-cellular development of Dictyostelium cells. Loss of FrmA leads to increased cell-cell adhesion and results in impaired multi-cellular development, slug migration and fruiting bodies. Further, mixing experiments show that FrmA null cells are excluded from the apex of wild-type mounds, to which cells that normally form the organising centre known as the tip sort. These data suggest a critical role for FrmA in regulating cell-cell adhesion, multi-cellular development and, in particular, the formation of the organising centre known as the tip.

Abstract
Absorbable sutures behave favourably in vitro and in an animal model. We report the outcome of flexor tendon injuries in a series of 272 consecutive patients treated over 45 months with a mean follow-up of 4 (range 3-12) months. Five hundred and seventy-six tendons were repaired in 416 digits. The patients were not randomised and all repairs were performed using a Strickland four-strand core technique. In 191 (73%) patients an absorbable core suture was used (Group 1) and in 81 (27%) a non-absorbable material was used (Group 2). There were six ruptures (2%) in Group 1 and two (2%) in Group 2. Using the original Strickland criteria, there were 72% excellent/good and 28% fair/poor results in the absorbable core suture group, and 73% and 27%, respectively, in the non-absorbable core suture group. This study suggests that appropriate absorbable core sutures can be used safely for flexor tendon repair.

Abstract
BACKGROUND Systemic glucocorticoids have been widely prescribed for use in infants and young children with acute viral bronchiolitis but the actual benefit of this intervention requires clarification. OBJECTIVES To systematically review the evidence on the effectiveness of systemic glucocorticoids for the treatment of infants and young children with acute viral bronchiolitis. SEARCH STRATEGY Multiple strategies were incorporated to maximize identification of suitable studies. The following databases were searched: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 3, 2003); MEDLINE (January 1966 to September 2003); Current Contents (1998 to 2000); EMBASE (January 1990 to September 2003); and Sci Search. Handsearches through cited references and contacts with experts were also used. SELECTION CRITERIA Only randomised controlled trials (RCT) were eligible for inclusion. Studies were included if participants were diagnosed with acute viral bronchiolitis and treated with systemic (oral, intramuscular or intravenous) corticosteroids. Three reviewers independently selected potentially relevant articles. Four reviewers evaluated these studies, determined eligibility and assessed the methodological quality of each RCT. DATA COLLECTION AND ANALYSIS The primary outcome of interest was length of hospital stay (LOS). Secondary outcomes were: respiratory rate, haemoglobin oxygen saturation, and hospital admission and revisit rates. Data were extracted independently by the four reviewers and the results compiled and compared. Two reviewers reassessed studies to clarify points of discrepancy in the data extraction and database entry processes. Missing data were requested from the authors or calculated from other data presented in the study report. MAIN RESULTS There was complete agreement on the inclusion of 13 trials and the exclusion of five studies. Two main study recruitment groups were identified: a) infants and young children within the first 48 hours of hospitalisation (10 trials), and b) outpatient infants and young children who were randomised from the emergency department and who may nor may not have required hospital admission (three trials).A total of 1,198 children aged 0 to 30 months were treated with the equivalent of 0.5 to 10 mg/kg of systemic prednisone for two to seven days. Outcomes of interest were not measured in each RCT. In the pooled analysis of seven trials, there was a decrease in LOS in treated children of 0.38 days (95% confidence interval (CI) -0.81 to 0.05), indicating no significant difference between treatment groups. In the pooled analysis of eight trials, the day three clinical score measured: a standard mean difference (SMD) of -0.20 (95% CI -0.73 to 0.32), indicating no difference between treatment groups. Subgroup analyses for base LOS and clinical score outcomes were performed on infants who were a) less than 12 months of age, b) all respiratory syncytial virus (RSV) positive, c) treated with less than 6 mg/kg of prednisone equivalent throughout the illness and d) first-time wheezers. These were limited by the small number of studies in each subgroup. Hospital admission rates were examined in three trials and no difference was seen between treatment groups (odds ratio (OR) 1.05 (95% CI 0.23 to 4.87). Readmission rates were reported in six studies; with no significant differences between treatment groups. Hospital revisit rates were reported in three studies, with a significant difference between treatment groups reported in one study only. The respiratory rate and haemoglobin oxygen saturation were reported descriptively in six RCTs; no differences were found between groups. Co-interventions (oxygen, supportive fluids and bronchodilators) were used similarly between treatment groups in all RCTs. AUTHORS' CONCLUSIONS No benefits were found in either LOS or clinical score in infants and young children treated with systemic glucocorticoids as compared to placebo. There were no differences in these outcomes between treatment groups; either in the pooled analysis or in any of the sub analyses. Among the three studies evaluating hospital admission rates following the initial hospital visit there was no difference between treatment groups. There were no differences found in respiratory rate, haemoglobin oxygen saturation, hospital revisit or readmission rates. Subgroup analyses were significantly limited by the low number of studies in each comparison. Marked study heterogeneity and occasionally conflicting direction of benefit between trials suggests that these results should be interpreted with caution. Specific data on the harm of corticosteroid therapy in this patient population are lacking. Available evidence suggests that corticosteroid therapy is not of benefit in this patient group.

Abstract
4616 Background: Talabostat is an oral small molecule inhibitor of fibroblast activation protein (FAP), a stromal enzyme with collagenase and dipeptidyl peptidase activity. Talabostat also upregulates cytokine and chemokine production, resulting in immune stimulation. Talabostat is active in pancreatic tumor xenograft models and enhances the activity of gemcitabine in mice. Therefore, a clinical trial in patients with metastatic pancreatic cancer was initiated. Methods: Open-label, single-arm, Phase 2 study in 60 evaluable patients with Stage IV pancreatic cancer. Study treatment is administered in 4 x 4-week cycles; gemcitabine 1g/m2 weekly for 4 weeks in Cycle 1, then once weekly for 3 of 4 weeks. Talabostat 200mcg tablets are given BID for 6 days following each gemcitabine infusion; dose-escalation to 300mcg BID is allowed post-Cycle 1. Either agent alone or in combination can be continued beyond 4 cycles depending on tolerability. Eligible patients have measureable Stage IV pancreatic adenocarcinoma (per RECIST) are chemotherapy-naive, have a KPS ≥50, no CNS metastases, transaminases < 3 X ULN, and total bilirubin < 1.5 X ULN. Primary endpoint is 6-month survival with secondary endpoints of overall survival, PFS, pain, and quality-of-life. Tumor response or PD is assessed per RECIST. Results: As of the cut-off date, 46 patients (30 men, 16 women, median age 66 [range 43–88 years]) have received study treatment. Most patients (76%) were Stage IV at original diagnosis, and 72% have a KPS of 80 or higher. Ten of 21 evaluable patients treated as of June 30, 2006 meet 6-month survival. Median overall survival is currently estimated at 4.8 months (95% CI: 2.9, NE) in all 46 patients, and median PFS at 3.5 months (95% CI: 2.0, 4.9). Tumor responses have been reported in 3 patients: one CR and 2 PRs. Pain and QOL have not yet been analyzed. AEs are consistent with those of gemcitabine, with the exception of edema in 28.3% of patients. Grade 3 anemia, neutropenia, hyponatremia hyperbilirubinemia, and increased alk phos are reported in 2 patients each. No Grade 4 AEs have been reported in more than one patient. Conclusions: Talabostat/gemcitabine shows activity in metastatic pancreatic cancer and can be safety administered. Enrollment completed in early January 2007, and final results will be presented at the annual meeting. No significant financial relationships to disclose.
