A comparison of the McGrath videolaryngoscope with direct laryngoscopy for rapid sequence intubation in the operating theatre: a multicentre randomised controlled trial.

Aspiration of gastric contents is a recognised complication during all phases of anaesthesia. The risk of this event becomes more likely with repeated attempts at tracheal intubation. There is a lack of clinical data on the effectiveness of videolaryngoscopy relative to direct laryngoscopy rapid sequence intubation in the operating theatre. We hypothesised that the use of a videolaryngoscope during rapid sequence intubation would be associated with a higher first pass tracheal intubation success rate than conventional direct laryngoscopy. In this multicentre randomised controlled trial, 1000 adult patients requiring tracheal intubation for elective, urgent or emergency surgery were allocated randomly to airway management using a McGrath™ MAC videolaryngoscope (Medtronic, Minneapolis, MN, USA) or direct laryngoscopy. Both techniques used a Macintosh blade. First-pass tracheal intubation success was higher in patients allocated to the McGrath group (470/500, 94%) compared with those allocated to the direct laryngoscopy group (358/500, 71.6%), odds ratio (95%CI) 1.31 (1.23-1.39); p < 0.001. This advantage was observed in both trainees and consultants. Cormack and Lehane grade ≥ 3 view occurred less frequently in patients allocated to the McGrath group compared with those allocated to the direct laryngoscopy group (5/500, 1% vs. 94/500, 19%, respectively; p < 0.001). Tracheal intubation with a McGrath videolaryngoscope was associated with a lower rate of adverse events compared with direct laryngoscopy (13/500, 2.6% vs. 61/500, 12.2%, respectively; p < 0.001). These findings suggest that the McGrath videolaryngoscope is superior to a conventional direct laryngoscope for rapid sequence intubation in the operating theatre.

Targeting GD2 after allogeneic SCT: effector cell composition defines the optimal use of ch14.18 and the bispecific antibody construct NG-CU (GD2-CD3).

We investigated whether T cell-recruiting bispecific anti-CD3/GD2 antibody NG-CU might be an alternative to therapeutic anti-GD2 monoclonal antibody (mAb) ch14.18, mediating complement-dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC) through natural killer (NK) cells for immunotherapy in high-risk/relapsed neuroblastoma after autologous/allogeneic stem cell transplantation (auto/alloSCT). Different antibody concentrations and effector-to-target ratios (E:T) were evaluated using xCELLigence RTCA system, peripheral blood mononuclear cells (PBMCs) (healthy donors and patients after alloSCT), and neuroblastoma cell lines (LS/LAN-1). Mean specific lysis of LS cells utilizing PBMCs from healthy donors and ch14.18 (1 µg/ml) was 40/66/75% after 12/24/48 h compared to 66/93/100% in the presence of NG-CU (100 ng/ml). NG-CU showed enhanced cytotoxicity compared to ch14.18, even at lower concentrations and E:T ratios, and completely eradicated LS cells after 72 h. To decipher the influence of effector cell subsets on lysis, different ratios of T and NK cells were tested. At a ratio of 1:1, ch14.18 was more effective than NG-CU. Using patient PBMCs taken at different time points posttransplant, significant lysis with both constructs was detectable depending on percentages and total numbers of T and NK cells; in the early posttransplant phase, NK cells were predominant and ch14.18 was superior, whereas later on, T cells represented the majority of immune cells and NG-CU was more effective. Our study highlights the importance of analyzing effector cell subsets in patients before initiating antibody-based therapy. Consequently, we propose an adjusted administration of both antibody constructs, considering the state of posttransplant immune recovery, to optimize anti-tumor activity.

Primary immunosuppressive TNI-based conditioning regimens in pediatric patients treated with haploidentical hematopoietic cell transplantation.

PURPOSE: This retrospective analysis aims to address the toxicity and efficacy of a modified total nodal irradiation (TNI)-based conditioning regimen before haploidentical hematopoietic cell transplantation (HCT) in pediatric patients. MATERIALS AND METHODS: Patient data including long-term follow-up were evaluated of 7 pediatric patients with malignant (n = 2) and non-malignant diseases (n = 5) who were treated by a primary TNI-based conditioning regimen. TNI was performed using anterior/posterior opposing fields. All patients received 7 Gy single-dose TNI combined with systemic agents followed by an infusion of peripheral blood stem cells (n = 7). All children had haploidentical family donors. RESULTS: Engraftment was reached in 6/7 children after a median time of 9.5 days; 1 child had primary graft failure but was successfully reconditioned shortly thereafter. After an average follow-up time of 103.5 months (range 8.8-138.5 months), event-free (EFS) and overall survival (OS) rates were 71.4% and 85.7%, respectively. One child with a non-malignant disease died 8.8 months after transplantation due to a relapse and a multiple organ failure. Follow-up data was available for 5/6 long-term survivors with a median follow-up (FU) of 106.2 months (range 54.5-138.5 months). Hypothyroidism and deficiency of sexual hormones was present in 3/5 patients each. Mean forced expiratory volume in 1 s (FEV1) after TNI was 71%; mean vital capacity (VC) was 78%. Growth failure (< 10th percentile) occurred in 2/5 patients (height) and 1/5 patient (weight). No secondary malignancies were reported. CONCLUSION: In this group of patients, a primary single-dose 7 Gy TNI-based conditioning regimen before HCT in pediatric patients allowed sustained engraftment combined with a tolerable toxicity profile leading to long-term OS/EFS. Late toxicity after a median FU of over 9 years includes growth failure, manageable hormonal deficiencies, and acceptable decrease in lung function.

No difference in survival after HLA mismatched versus HLA matched allogeneic stem cell transplantation in Ewing sarcoma patients with advanced disease.

Patients with advanced Ewing sarcoma (AES) carry a poor prognosis. Retrospectively, we analyzed 66 AES patients treated with allogeneic stem cell transplantation (allo-SCT) receiving HLA-mismatched (group A, n = 39) versus HLA-matched grafts (group B, n = 27). Median age at diagnosis was 13 years, and 15 years (range 3-49 years) at allo-SCT. The two groups did not differ statistically in distribution of gender, age, remission status/number of relapses at allo-SCT, or risk stratum. 9/39 (23%) group A versus 2/27 (7%) group B patients developed severe acute graft versus host disease (GvHD). Of patients alive at day 100, 7/34 (21%) group A versus 9/19 (47%) group B patients had developed chronic GvHD. In group A, 33/39 (85%) versus 20/27 (74%) group B patients died of disease and 1/39 (3%) versus 1/27 (4%) patients died of complications, respectively. Altogether 12/66 (18%) patients survived in CR. Median EFS 24 months after allo-SCT was 20% in both groups, median OS was 27% (group A) versus 17% (group B), respectively. There was no difference in EFS and OS in AES patients transplanted with HLA-mismatched versus HLA-matched graft in univariate and multivariate analyses. In this analysis, CR at allo-SCT is a condition for survival (p < 0.02).

Prophylactic salpingectomy for prevention of ovarian cancer at the time of elective laparoscopic cholecystectomy.

BACKGROUND: Most serous ovarian cancers are now understood to originate in the fallopian tubes. Removing the tubes (salpingectomy) likely reduces the risk of developing high-grade serous ovarian cancer. Numerous gynaecological societies now recommend prophylactic (or opportunistic) salpingectomy at the time of gynaecological surgery in appropriate women, and this is widely done. Salpingectomy at the time of non-gynaecological surgery has not been explored and may present an opportunity for primary prevention of ovarian cancer. METHODS: This study investigated whether prophylactic salpingectomy with the intention of reducing the risk of developing ovarian cancer would be accepted and could be accomplished at the time of elective laparoscopic cholecystectomy. Women aged at least 45 years scheduled for elective laparoscopic cholecystectomy were recruited. They were counselled and offered prophylactic bilateral salpingectomy at the time of cholecystectomy. Outcome measures were rate of accomplishment of salpingectomy, time and procedural steps needed for salpingectomy, and complications. RESULTS: A total of 105 patients were included in the study. The rate of acceptance of salpingectomy was approximately 60 per cent. Salpingectomy was performed in 98 of 105 laparoscopic cholecystectomies (93·3 per cent) and not accomplished because of poor visibility or adhesions in seven (6·7 per cent). Median additional operating time was 13 (range 4-45) min. There were no complications attributable to salpingectomy. One patient presented with ovarian cancer 28 months after prophylactic salpingectomy; histological re-evaluation of the tubes showed a previously undetected, focal serous tubal intraepithelial carcinoma. CONCLUSION: Prophylactic salpingectomy can be done during elective laparoscopic cholecystectomy.

ANTECEDENTES: La mayoría de carcinomas serosos de ovario se originan en las trompas de Falopio. La exéresis de las trompas (salpingectomía) probablemente reduce el riesgo de desarrollar un carcinoma seroso ovárico de alto grado. Numerosas sociedades ginecológicas recomiendan efectuar una salpingectomía profiláctica (u oportunista) en el momento de una cirugía ginecológica en determinadas mujeres, y esta conducta está ampliamente difundida. Sin embargo, no se ha analizado la realización de la salpingectomía durante cirugías no ginecológicas como forma de prevención primaria del carcinoma ovárico. MÉTODOS: Determinar si la salpingectomía profiláctica con intención de reducir el riesgo de desarrollar cáncer de ovario sería aceptada y podría llevarse a cabo durante una colecistectomía laparoscópica electiva. Se reclutaron mujeres ≥ 45 años de edad programadas para colecistectomía laparoscópica electiva. A todas ellas se les aconsejó y ofreció la realización de una salpingectomía bilateral profiláctica en el momento de su colecistectomía. Las variables analizadas fueron la tasa de realización de la salpingectomía, la duración y las etapas quirúrgicos para efectuar este procedimiento, y las complicaciones. RESULTADOS: La aceptación de la salpingectomía fue aproximadamente del 60%. La salpingectomía se realizó en 98 de 105 colecistectomías laparoscópicas (93%) y no se pudo realizar en 7 pacientes (7%) por escasa visibilidad o adherencias. La mediana del tiempo quirúrgico adicional fue de 13 (rango 4-45) minutos. No hubo complicaciones atribuibles a la salpingectomía. Una paciente presentó cáncer de ovario 28 meses después de la salpingectomía profiláctica; la reevaluación histológica de las trompas mostró un carcinoma intraepitelial seroso focal tubárico (serous tubal intraepithelial carcinoma, STIC) no detectado previamente. CONCLUSIÓN: La salpingectomía profiláctica se puede realizar durante la colecistectomía laparoscópica electiva.

Pediatric Langerhans cell histiocytosis: the impact of mutational profile on clinical progression and late sequelae.

Langerhans cell histiocytosis (LCH) is a clonal histiocytic disorder with recurrent mutations of BRAF and MAP2K1, but data on the impact of genetic features on progression and long-term sequelae are sparse. Cases of pediatric LCH with long-term follow-up from our institution were analyzed for mutations in BRAFV600 and MAP2K1 exons 2 and 3 by immunostaining with mutation-specific VE1 antibody, as well as allele-specific PCR and sequencing, respectively. Clinical and follow-up data were obtained from our files and a questionnaire sent to all former patients. Sixteen of 37 (43%) evaluable cases showed BRAFV600E, one case a BRAFV600D and eleven (30%) a MAP2K1 mutation. Nine cases were unmutated for both genes. All cases with risk organ involvement showed either BRAFV600 or MAP2K1 mutation. Patients with BRAFV600 mutation excluding Hashimoto-Pritzker cases had a significantly higher risk for relapses (p = 0.02). Long-term sequelae were present in 19/46 (41%) patients (median follow-up 12.5 years, range 1.0 to 30.8) with a trend for higher rates in mutated cases (mutated = 9/17, 53% versus non-BRAFV600/MAP2K1 mutated = 2/7, 29%). In addition, 8/9 cases with skin involvement including all Hashimoto-Pritzker cases (n = 3) were positive for BRAFV600E. Infants below 2 years more frequently had BRAFV600 mutations (p = 0.013). Despite favorable prognosis, pediatric LCH shows a high frequency of relapses and long-term medical sequelae.

Mechanisms of lymphatic system-specific viral replication and its potential role in autoimmune disease.

Viral infections can be fatal because of the direct cytopathic effects of the virus or the induction of a strong, uncontrolled inflammatory response. Virus and host intrinsic characteristics strongly modulate the outcome of viral infections. Recently we determined the circumstances under which enhanced replication of virus within the lymphoid tissue is beneficial for the outcome of a disease. This enforced viral replication promotes anti-viral immune activation and, counterintuitively, accelerates virus control. In this review we summarize the mechanisms that contribute to enforced viral replication. Antigen-presenting cells and CD169+ macrophages exhibit enforced viral replication after infection with the model viruses lymphocytic choriomeningitis virus (LCMV) and vesicular stomatitis virus (VSV). Ubiquitin-specific peptidase 18 (Usp18), an endogenous type I interferon blocker in CD169+ macrophages, has been identified as a proviral gene, as are B cell activating factor (BAFF) and carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1). Lymphotoxins (LT) strongly enhance viral replication in the spleen and lymph nodes. All these factors modulate splenic architecture and thereby promote the development of CD169+ macrophages. Tumor necrosis factor alpha (TNF-α) and nuclear factor kappa-light-chain-enhancer of activated B cell signaling (NF-κB) have been found to promote the survival of infected CD169+ macrophages, thereby similarly promoting enforced viral replication. Association of autoimmune disease with infections is evident from (1) autoimmune phenomena described during a chronic virus infection; (2) onset of autoimmune disease simultaneous to viral infections; and (3) experimental evidence. Involvement of virus infection during onset of type I diabetes is strongly evident. Epstein-Bar virus (EBV) infection was discussed to be involved in the pathogenesis of systemic lupus erythematosus. In conclusion, several mechanisms promote viral replication in secondary lymphatic organs. Identifying such factors in humans is a challenge for future studies.

Cognitive function in patients with coronary artery disease: A literature review.

Objective Cognitive function impairment is a well-documented complication of cerebrovascular disease (CBVD). Less is known about what factors affect the deterioration of cognitive function in patients with coronary artery disease (CAD). The aim of this review is to explore recent studies investigating factors associated with cognitive function in patients with CAD. Methods Studies published from 2010 to 2016 were identified through a systematic search of MEDLINE/PubMed and were included if they addressed factors affecting cognitive function in the CAD population. Results Of the 227 publications identified, 32 were selected for the review. Five factors tentatively affecting cognitive function in patients with CAD were identified: coronary artery bypass grafting (CABG) surgery, apolipoprotein E4 (APOE4) genotype, left ventricular ejection fraction (LVEF), medication use, and various hormones and biomarkers. Conclusion New techniques in CABG surgery have proven to alleviate postoperative cognitive decline. Researchers are still debating the effects of APOE4 genotype, LVEF, and the use of cardiovascular medications on cognitive function. Thyroid hormones and biomarkers are associated with cognitive function, but the exact nature of the association is debatable. Longitudinal studies should clarify those associations. In addition, cross-sectional studies addressing other causes of cognitive decline in patients with CAD are warranted.

Changes in trauma management following the implementation of the whole-body computed tomography: a retrospective multi-centre study based on the trauma registry of the German Trauma Society (TraumaRegister DGU®).

OBJECTIVES: Whole-body computed tomography (WBCT) plays an increasingly important role in the diagnostic assessment of trauma room patients. It is still unclear whether its use has led to changes of trauma room procedures and patient outcomes. METHODS: In a retrospective multi-centric study based on the trauma registry of the German Trauma Society (TraumaRegister DGU®), we analysed patients with an ISS ≥ 9 between 2002 and 2013. Two periods of time, i.e. up to 3 years preceding (pre-WBCT) and up to 3 years following the introduction of the WBCT (WBCT-group), were assessed separately for every hospital (TR-DGU Project ID 2014-020). RESULTS: 19,838 patients underwent treatment in 77 hospitals. Of these, 5621 were assigned to the pre-WBCT group and 11,307 to the WBCT group. Basic data did not differ relevantly. The time spent in the trauma room decreased from 77.9 min (pre-WBCT) to 63.3 min (WBCT). Following the introduction of the trauma scan, the number of diagnoses per patient increased from 4.6 to 5.1. The percentage of patients who underwent surgery immediately after the completion of trauma room procedures decreased from 44.5 to 39.1%. There was an increase in mortality from 15.7 to 15.9%. CONCLUSIONS: Routine use of WBCT is not superior to a combination of conventional radiography, ultrasound and focused CT in terms of mortality. The entire process involving the introduction of the trauma scan and the further development of algorithms has caused changes that can be observed in the trauma room setting.

A randomized trial of induction docetaxel-cisplatin-5FU followed by concomitant cisplatin-RT versus concomitant cisplatin-RT in nasopharyngeal carcinoma (GORTEC 2006-02).

Background: Concomitant chemotherapy (CT)-radiotherapy (RT) is a standard of care in locally advanced nasopharyngeal carcinoma (NPC) and a role for induction CT is not established. Methods: Patients with locally advanced NPC, WHO type 2 or 3, were randomized to induction TPF plus concomitant cisplatin-RT or concomitant cisplatin-RT alone. The TPF regimen consisted of three cycles of Docetaxel 75 mg/m2 day 1; cisplatin 75 mg/m2 day 1; 5FU 750 mg/m2/day days 1-5. RT consisted of 70 Gy in 7 weeks plus concomitant cisplatin 40 mg/m2 weekly. Results: A total of 83 patients were included in the study. Demographics and tumour characteristics were well balanced between both arms. Most of the patients (95%) in the TPF arm received three cycles of induction CT. The rate of grade 3-4 toxicity and the compliance (NCI-CTCAE v3) during cisplatin-RT were not different between both arms. With a median follow-up of 43.1 months, the 3-year PFS rate was 73.9% in the TPF arm versus 57.2% in the reference arm [hazard ratio (HR) = 0.44; 95% confidence interval (CI): 0.20-0.97, P = 0.042]. Similarly the 3 years overall survival rate was 86.3% in the TPF arm versus 68.9% in the reference arm (HR = 0.40; 95% CI: 0.15-1.04, P = 0.05). Conclusion: In conclusion, several important aspects can be emphasized: the compliance to induction TPF was good and TPF did not compromise the tolerance of the concomitant RT-cisplatin phase. The improved PFS and overall survival rates needs to be confirmed by further trials.

Quantification of the ossification of the lateral cuneiform in the feet of young children with unilateral congenital talipes equinovarus.

AIMS: After the initial correction of congenital talipes equinovarus (CTEV) using the Ponseti method, a subsequent dynamic deformity is often managed by transfer of the tendon of tibialis anterior (TATT) to the lateral cuneiform. Many surgeons believe the lateral cuneiform should be ossified before surgery is undertaken. This study quantifies the ossification process of the lateral cuneiform in children with CTEV between one and three years of age. PATIENTS AND METHODS: The length, width and height of the lateral cuneiform were measured in 43 consecutive patients with unilateral CTEV who had been treated using the Ponseti method. Measurements were taken by two independent observers on standardised anteroposterior and lateral radiographs of both feet taken at one, two and three years of age. RESULTS: All dimensions of the lateral cuneiform on the affected side increased annually but remained smaller than the corresponding dimensions of the unaffected foot (p < 0.01). The lateral cuneiform resembled a 9 mm cube at two years and an 11 mm cube at three years. CONCLUSION: At one and two years, the ossification centre of the lateral cuneiform may not be large enough to accommodate a drill hole for tendon transfer. However, by three years, it has undergone sufficient ossification to do so. Cite this article: Bone Joint J 2017;99-B:1109-14.

MALT1 is an intrinsic regulator of regulatory T cells.

Regulatory T cells (Tregs) are crucial for the maintenance of immunological self-tolerance and their absence or dysfunction can lead to autoimmunity. However, the molecular pathways that govern Treg biology remain obscure. In this study, we show that the nuclear factor-κB signalling mediator mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) is an important novel regulator of both Tregs originating in the thymus ('natural' or nTregs) and Tregs induced to differentiate from naive thymocyte helper (Th) cells in the periphery ('induced' or iTregs). Our examination of mice deficient for MALT1 revealed that these mutants have a reduced number of total Tregs. In young Malt1-/- mice, nTregs are totally absent and iTreg are diminished in the periphery. Interestingly, total Treg numbers increase in older Malt1-/- mice as well as in Malt1-/- mice subjected to experimentally induced inflammation. iTregs isolated from WT and Malt1-/- mice were indistinguishable with respect to their ability to suppress the activities of effector T cells, but Malt1-/- iTregs expressed higher levels of Toll-like receptor (TLR) 2. Treatment of WT and Malt1-/- Th cells in vitro with the TLR2 ligand Pam3Cys strongly enhanced the induction and proliferation of Malt1-/- iTregs. Our data suggest that MALT1 supports nTreg development in the thymus but suppresses iTreg induction in the periphery during inflammation. Our data position MALT1 as a key molecule that contributes to immune tolerance at steady-state while facilitating immune reactivity under stress conditions.

High energy proton induced radiation damage of rare earth permanent magnet quadrupoles.

Permanent magnet quadrupoles (PMQs) are an alternative to common electromagnetic quadrupoles especially for fixed rigidity beam transport scenarios at particle accelerators. Using those magnets for experimental setups can result in certain scenarios, in which a PMQ itself may be exposed to a large amount of primary and secondary particles with a broad energy spectrum, interacting with the magnetic material and affecting its magnetic properties. One specific scenario is proton microscopy, where a proton beam traverses an object and a collimator in which a part of the beam is scattered and deflected into PMQs used as part of a diagnostic system. During the commissioning of the PRIOR (Proton Microscope for Facility for Antiproton and Ion Research) high energy proton microscope facility prototype at Gesellschaft für Schwerionenforschung in 2014, a significant reduction of the image quality was observed which was partially attributed to the demagnetization of the used PMQ lenses and the corresponding decrease of the field quality. In order to study this phenomenon, Monte Carlo simulations were carried out and spare units manufactured from the same magnetic material-single wedges and a fully assembled PMQ module-were deliberately irradiated by a 3.6 GeV intense proton beam. The performed investigations have shown that in proton radiography applications the above described scattering may result in a high irradiation dose in the PMQ magnets. This did not only decrease the overall magnetic strength of the PMQs but also caused a significant degradation of the field quality of an assembled PMQ module by increasing the parasitic multipole field harmonics which effectively makes PMQs impractical for proton radiography applications or similar scenarios.

[Metastatic mechanisms of uterine malignancies and therapeutic consequences]. / Metastasierung von Malignomen des Uterus und therapeutische Konsequenzen.

Malignancies of the uterus metastasize by direct invasion of neighboring structures, lymphatically or hematogenously. Endometrial and cervical cancers lymphatically spread to the pelvic and para-aortic lymph nodes. For endometrial cancer the depth of myometrial invasion, lymphosvascular space involvement (LVSI) and a microcystic, elongated and fragmented (MELF) glandular invasion pattern are predictors for lymph node metastases. Metastases to the pelvic lymph nodes occur in approximately 10 % of endometrial cancer patients and in 30 % of these cases the para-aortic lymph nodes are also involved. Sentinel lymph node biopsy is possible for clinical stage I endometrial cancer and early stages of cervical cancer but is not yet routine. The presence of LVSI is considered to be the strongest predictor of distant metastases, particularly if assessed by immunohistochemistry with antibodies against factor VIII-related antigen or CD31. Endometrioid and clear cell carcinomas can hematogenously metastasize to the lungs, bones, liver and brain and can rarely be manifested as a solitary metastasis. In contrast, serous carcinomas can show extensive peritoneal spread. To date molecular biomarkers cannot predict the occurrence of distant metastasis. Overexpression of P53, p16 and L1CAM have been identified as negative prognostic factors and are associated with the prognostically unfavorable serous tumor type. The metastatic spread of squamous cell cervical cancer is strongly associated with tumor volume. Microinvasive carcinomas have a very low rate of parametrial and lymph node involvement and do not require radical hysterectomy. In contrast, lymph node metastases occur in up to 50 % of bulky stages IB and II cervical cancers. Distant metastases can occur in the lungs, liver, bones and brain. Molecular biomarkers have not been shown to predict metastatic spread. In well-differentiated adenocarcinoma of the cervix the pattern of invasion is strongly predictive for the presence of lymph node metastases, irrespective of tumor size and depth of invasion.

[Recommendations for treatment and prevention of herpes zoster and associated pain in aged adults]. / Recommandations pour le traitement et la prévention du zona et des douleurs associées chez la personne âgée.

Initiated within the first 72 hours of the rash, prescribing antiviral drugs reduces both acute neuralgia (AN) and later complications and especially postherpetic neuralgia (PHN). But their analgesic as well as preventative effect on AN and PHN is modest. Combination with analgesic drugs is more often needed for pain management. However, the pharmacological management of pain, in the context of old patients' frailty, co-morbidities and often polypharmacy, must be carefully considered. Based on analyses of the evidences from the literature, this review presents the therapeutic options we have at one's disposal and proposes a stepwise management for both AN and PHN specifically designed for aged population.

Favorable outcome in children and adolescents with a high proportion of advanced phase disease using single/multiple autologous or matched/mismatched allogeneic stem cell transplantations.

We determined the indication, outcome, and risk factors of single and multiple hematopoietic stem cell transplantation(s) (HSCT) in children and adolescents mostly with advanced disease. Forty-one out of 483 patients (8.5 %; median age 9 years) diagnosed at the University of Leipzig with hematological and oncological diseases required HSCT from 1999 to 2011. Patients had overall survival (OS) of 63 ± 10 and 63 ± 16 %, event-free survival (EFS) of 57 ± 10 and 42 ± 16 %, relapse incidence (RI) of 39 ± 10 and 44 ± 18 % and nonrelapse mortality (NRM) of 4 ± 4 and 13 ± 9 % at 10 years after one or more allogeneic and autologous HSCT, respectively. One patient in CR1 and five with advanced disease received two HSCT. Four of the six patients maintained/achieved CR for a median of 13 months. Three died of progression and one of NRM. Two patients had a third HSCT and one survived in CR +231 days after HSCT. Risk factors for OS and EFS were disease stage at HSCT and EBMT risk score. Center (pediatric or JACIE accredited pediatric/adult) was not a determinant for survival. Pediatric single and multiple HSCT are important curative approaches for high-risk malignant diseases with low NRM. Efforts to reduce high RI remain the major aim.

No effect of the cyclooxygenase-2 inhibitor etoricoxib on pre-emptive and post-operative analgesia in visceral surgery: results of a randomized controlled trial.

BACKGROUND: Pre-emptive analgesia in perioperative care has potential benefits for patients. The pre-emptive and postoperative analgesic effects of the cyclooxygenase-2 inhibitor etoricoxib have been investigated using a 2 × 2 factorial trial design. METHODS: According to the 2 × 2 factorial study design, 103 patients scheduled for visceral surgery, were randomly allocated to two groups prior to surgery. Patients could receive either etoricoxib or placebo (to investigate pre-emptive analgesia). Subsequent to surgery, patients randomly received either etoricoxib or placebo, again. It follows, that four treatment modalities (continuous or replaced intervention) result, to investigate postoperative analgesia. Main Outcome Measure was the cumulative morphine use 48 h post-surgery. Other outcomes included pain intensities, pain thresholds and sensory detection. RESULTS: Eighty-six patients (female n = 42; mean age 53.82 ± 13.61 years) were evaluated on the basis of an intention to treat analysis. Pre-emptive administration of 120 mg etoricoxib did not significantly reduce the cumulative morphine dose within the first 48 h after surgery, when compared to the administration of placebo. The analysis of the post-operative treatment groups showed a non-significant 8% reduction in morphine dose during the continuous administration of etoricoxib. There were no changes in sensory perception as detected with QST before and after surgery or between groups. CONCLUSIONS: The effect of administering etoricoxib was not superior to placebo in reducing the morphine dose required for postoperative analgesia. The lack of changes in peripheral nociception suggests that central algetic mechanisms are of higher impact in the development of postoperative pain following abdominal or thoracic surgery.

Improved immune recovery after transplantation of TCRαß/CD19-depleted allografts from haploidentical donors in pediatric patients.

Immune recovery was retrospectively analyzed in a cohort of 41 patients with acute leukemia, myelodysplastic syndrome and nonmalignant diseases, who received αß T- and B-cell-depleted allografts from haploidentical family donors. Conditioning regimens consisted of fludarabine or clofarabine, thiotepa, melphalan and serotherapy with OKT3 or ATG-Fresenius. Graft manipulation was carried out with anti-TCRαß and anti-CD19 Abs and immunomagnetic microbeads. The γδ T cells and natural killer cells remained in the grafts. Primary engraftment occurred in 88%, acute GvHD (aGvHD) grades II and III-IV occurred in 10% and 15%, respectively. Immune recovery data were available in 26 patients and comparable after OKT3 (n=7) or ATG-F (n=19). Median time to reach >100 CD3+ cells/µL, >200 CD19+ cells/µL and >200 CD56+ cells/µL for the whole group was 13, 127 and 12.5 days, respectively. Compared with a historical control group of patients with CD34+ selected grafts, significantly higher cell numbers were found for CD3+ at days +30 and +90 (267 vs 27 and 397 vs 163 cells/µL), for CD3+4+ at day +30 (58 vs 11 cells/µL) and for CD56+ at day +14 (622 vs 27 cells/µL). The clinical impact of this accelerated immune recovery will be evaluated in an ongoing prospective multicenter trial.
