    We aimed to compare Postoperative Blood Salvage (PBS) with Allogeneic Blood Transfusion (ABT) in patients undergoing Total Hip and Knee Arthroplasty (THA, TKA).  A bibliographic research was carried out in order to review the literature dedicated to postoperative blood salvage in major orthopaedic surgery, excluding papers dealing exclusively with preoperative autologous donation, intraoperative blood salvage and ABT. PBS and ABT were compared according to complications, costs and duration of hospitalization. PBS effectiveness in reducing ABT was also assessed. PBS system is useful for reducing the complication rate and the length of hospital stay if compared to ABT. Costs for the reinfusion of unwashed shed blood, washed blood, and allogeneic transfusion are controversial among the different authors. Several papers demonstrate that PBS significantly reduces the need of postoperative ABT in both THA and TKA, while there is low evidence that PBS does not affect the risk of surgical wound complications. To reduce potential risks related to PBS, including non-hemolytic febrile reaction, the reinfusion of saved blood should begin within 4-6 hours after the start of collection through the wound drainage. According to literature, PBS appears to be a valid alternative to ABT, which is the standard treatment for postoperative anemia in THA and TKA. Contraindications to PBS must be ruled out before recommending it to patients undergoing major orthopaedic procedures.

    Background Requirements for allogeneic red cell transfusion after total knee arthroplasty are still high (20–50%), and salvage and reinfusion of unwashed, filtered post-operative shed blood is an established method for reducing transfusion requirements following this operation. We performed a cost analysis to ascertain whether this alternative is likely to be cost-effective. Materials and methods Data from 1,093 consecutive primary total knee arthroplasties, managed with (reinfusion group, n=763) or without reinfusion of unwashed salvaged blood (control group, n=330), were retrospectively reviewed. The costs of low-vacuum drains, shed blood collection canisters (Bellovac ABT®, Wellspect HealthCare and ConstaVac CBC II®, Stryker), shed blood reinfusion, acquisition and transfusion of allogeneic red cell concentrate, haemoglobin measurements, and prolonged length of hospital stay were used for the blood management cost analysis. Results Patients in the reinfusion group received 152±64 mL of red blood cells from postoperatively salvaged blood, without clinically relevant incidents, and showed a lower allogeneic transfusion rate (24.5% vs 8.5%, for the control and reinfusion groups, respectively; p =0.001). There were no differences in post-operative infection rates. Patients receiving allogeneic transfusions stayed in hospital longer (+1.9 days [95% CI: 1.2 to 2.6]). As reinfusion of unwashed salvaged blood reduced the allogeneic transfusion rate, both reinfusion systems may provide net savings in different cost scenarios (€ 4.6 to € 106/patient for Bellovac ABT, and € −51.9 to € 49.9/patient for ConstaVac CBCII). Discussion Return of unwashed salvaged blood after total knee arthroplasty seems to save costs in patients with pre-operative haemoglobin between 12 and 15 g/dL. It is not cost-saving in patients with a pre-operative haemoglobin >15 g/dL, whereas in those with a pre-operative haemoglobin cost-saving, its efficacy could be increased by

    The use of intraoperative cell salvage and autologous blood transfusion has become an important method of blood conservation. The main aim of autologous transfusion is to reduce the need for allogeneic blood transfusion and its associated complications. Allogeneic blood transfusion has been associated with increased risk of tumour recurrence, postoperative infection, acute lung injury, perioperative myocardial infarction, postoperative low-output cardiac failure, and increased mortality. We have reviewed the current evidence for cell salvage in modern surgical practice and examined the controversial issues, such as the use of cell salvage in obstetrics, and in patients with malignancy, or intra-abdominal or systemic sepsis. Cell salvage has been demonstrated to be safe and effective at reducing allogeneic blood transfusion requirements in adult elective surgery, with stronger evidence in cardiac and orthopaedic surgery. Prolonged use of cell salvage with large-volume autotransfusion may be associated with dilution of clotting factors and thrombocytopenia, and regular laboratory or near-patient monitoring is required, along with appropriate blood product use. Cell salvage should be considered in all cases where significant blood loss (>1000 ml) is expected or possible, where patients refuse allogeneic blood products or they are anaemic. The use of cell salvage in combination with a leucocyte depletion filter appears to be safe in obstetrics and cases of malignancy; however, further trials are required before definitive guidance may be provided. The only absolute contraindication to the use of cell salvage and autologous blood transfusion is patient refusal.

    Purpose: Identification of patients most likely to benefit from salvage radiotherapy (RT) using postoperative (postop) prostate-specific antigen (PSA) kinetics. Methods and Materials: From 1984 to 2004, 81 patients who fit the following criteria formed the study population: undetectable PSA after radical prostatectomy (RP); pathologically negative nodes; biochemical relapse defined as a persistently detectable PSA; salvage RT; and two or more postop PSAs available before salvage RT. Salvage RT included the whole pelvic nodes in 55 patients and 4 months of total androgen suppression in 56 patients. The median follow-up was >5 years. All relapses were defined as a persistently detectable PSA. Kaplan-Meier and Cox proportional hazards multivariable analysis were performed for all clinical, pathological, and treatment factors predicting for biochemical relapse-free survival (bRFS). Results: There were 37 biochemical relapses observed after salvage RT. The 5-year bRFS after salvage RT for patients with postop prostate-specific antigen velocity ≤1 vs. >1 ng/ml/yr was 59% vs. 29%, p = 0.002. In multivariate analysis, only postop PSAV (p = 0.0036), pre-RT PSA level ≤1 (p = 0.037) and interval-to-relapse >10 months (p = 0.012) remained significant, whereas pelvic RT, hormone therapy, and RT dose showed a trend (p = ∼0.06). PSAV, but not prostate-specific antigen doubling time, predicted successful salvage RT, suggesting an association of zero-order kinetics with locally recurrent disease. Conclusions: Postoperative PSA velocity independently predicts for the failure of salvage RT and can be considered in addition to high-risk features when selecting patients in need of systemic therapy following biochemical failure after RP. For well-selected patients, salvage RT can achieve high cure rates

    The outcomes and toxicities of locoregionally recurrent non-small-cell lung cancer (NSCLC) patients treated with curative radiotherapy were evaluated in the modern era. Fifty-seven patients receiving radical radiotherapy for locoregionally recurrent NSCLC without distant metastasis after surgery from 2004 to 2014 were reviewed. Forty-two patients were treated with concurrent chemoradiotherapy (CCRT), and 15 patients with radiotherapy alone. The median radiation dose was 66 Gy (range, 45 to 70 Gy). Lung function change after radiotherapy was evaluated by comparing pulmonary function tests before and at 1, 6, and 12 months after radiotherapy. Median follow-up was 53.6 months (range, 12.0 to 107.5 months) among the survivors. The median overall survival (OS) and progression-free survival (PFS) were 54.8 months (range, 3.0 to 116.9 months) and 12.2 months (range, 0.8 to 100.2 months), respectively. Multivariate analyses revealed that single locoregional recurrence focus and use of concurrent chemotherapy were significant prognostic factors for OS (p = 0.048 and p = 0.001, respectively) and PFS (p = 0.002 and p = 0.026, respectively). There was no significant change in predicted forced expiratory volume in one second after radiotherapy. Although diffusing lung capacity for carbon monoxide decreased significantly at 1 month after radiotherapy (p < 0.001), it recovered to pretreatment levels within 12 months. Acute grade 3 radiation pneumonitis and esophagitis were observed in 3 and 2 patients, respectively. There was no chronic complication observed in all patients. Salvage radiotherapy showed good survival outcomes without severe complications in postoperative locoregionally recurrent NSCLC patients. A single locoregional recurrent focus and the use of CCRT chemotherapy were associated with improved survival. CCRT should be considered as a salvage treatment in patients with good prognostic factors.

    Stored red blood cells (RBCs) are deficient in 2,3-diphosphoglycerate (2,3-DPG), but it is unclear how autologous salvaged blood (ASB) compares with stored blood and how rapidly 2,3-DPG levels return to normal after transfusion. Therefore, we compared levels of 2,3-DPG in stored versus ASB RBCs and in patients' blood after transfusion. Twenty-four patients undergoing multilevel spine fusion surgery were enrolled. We measured 2,3-DPG and the oxyhemoglobin dissociation curve (P50) in samples taken from the ASB and stored blood bags before transfusion and in blood samples drawn from patients before and after transfusion. The mean storage duration for stored RBCs was 24 ± 8 days. Compared with fresh RBCs, stored RBCs had decreased 2,3-DPG levels (by approximately 90%; P levels recovered gradually over 3 postoperative days in patients who received stored RBCs. Stored RBCs, but not ASB RBCs, have decreased levels of 2,3-DPG and a left-shift in the oxyhemoglobin dissociation curve. Postoperatively, 2,3-DPG levels remain below preoperative baseline levels for up to 3 postoperative days in patients who receive stored RBCs but are unchanged in those who receive only ASB RBCs.

    In contrast to primary radiotherapy, no reports are available for a hydrogel spacer application in postoperative salvage radiotherapy for prostate cancer. A 77-year-old patient presented 20 years after radical prostatectomy with a digitally palpable local recurrence at the urethrovesical anastomosis (PSA 5.5 ng/ml). The hydrogel spacer (10 ml, SpaceOAR trademark) was injected between the local recurrence and rectal wall under transrectal ultrasound guidance. Treatment planning was performed with an intensity-modulated technique up to a total dose of 76 Gy in 2-Gy fractions. The same planning was performed based on computed tomography before spacer injection for comparison. The local recurrence, initially directly on the rectal wall, could be displaced more than 1 cm from the rectal wall after hydrogel injection. With a mean total dose of 76 Gy to the planning target volume, rectal wall volumes included in the 70 Gy, 60 Gy, 50 Gy isodoses were 0 cm 3 , 0 cm 3 , and 0.4 cm 3 with a spacer and 2.9 cm 3 , 4.5 cm 3 , and 6.2 cm 3 without a spacer, respectively. The patient reported rectal urgency during radiotherapy, completely resolving after the end of treatment. The PSA level was 5.4 ng/ml a week before the end of radiotherapy and dropped to 0.9 ng/ml 5 months after radiotherapy. A hydrogel spacer was successfully applied for dose-escalated radiotherapy in a patient with macroscopic local prostate cancer recurrence at the urethrovesical anastomosis to decrease the dose at the rectal wall. This option can be considered in specifically selected patients. (orig.) [de

    Mechanical cell salvage is increasingly used during cardiac surgery. Although this procedure is considered safe, it is unknown whether it affects the red blood cell (RBC) function, especially the RBC aggregation, deformability, and the contents of 2,3-diphosphoglycerate (2,3-DPG). This study examines the following: (1) whether the cell salvage procedure influences RBC function; and (2) whether retransfusion of the salvaged blood affects RBC function in patients. Forty patients undergoing cardiac surgery with cardiopulmonary bypass were randomly allocated to a cell saver group (n = 20) or a control group (n = 20). In the cell saver group, the blood aspirated from the wound area and the residual blood from the heart-lung machine were processed with a continuous-flow cell saver before retransfusion. In the control group this blood was retransfused without processing. The RBC aggregation and deformability were measured with a laser-assisted optical rotational cell analyzer and 2,3,-DPG by conventional laboratory test. The cell saver procedure did not influence the RBC aggregation but significantly reduced the RBC deformability (p = 0.007) and the content of RBC 2,3-DPG (p = 0.032). However, in patients receiving the processed blood, their intraoperative and postoperative RBC aggregation, deformability, and 2,3-DPG content did not differ from those of the control patients. Both groups of patients had a postoperative drop of RBC function as a result of hemodilution. The mechanical cell salvage procedure reduces the RBC deformability and the cell 2,3-DPG content. Retransfusion of the processed blood by cell saver does not further compromise the RBC function in patients undergoing cardiac surgery with cardiopulmonary bypass.

    The study compared the effects of three blood concentration techniques after cardiopulmonary bypass on clinical hemostatic and ex-vivo rheological parameters. Residual blood of patients undergoing elective cardiac surgery was processed by centrifugation, cell salvage or ultrafiltration, and retransfused (n = 17 per group). Study parameters included blood loss, (free) hemoglobin, hematocrit, fibrinogen and erythrocyte aggregation, deformability and 2,3-diphosphoglycerate content. Patient characteristics were similar between groups. Ultrafiltration was associated with the highest weight of the transfusion bag [649 ± 261 vs. 320 ± 134 g (centrifugation) and 391 ± 158 g (cell salvage); P levels in the transfusion bag. Retransfusion of cell saver blood induced the largest gain in postoperative patient hemoglobin levels when compared to centrifugation and ultrafiltration, and was associated with the largest increase in 2,3-diphosphoglycerate when compared to ultrafiltration (Δ2,3-diphosphoglycerate 1.34 ± 1.92 vs. -0.77 ± 1.56 mmol/l; P = 0.03). Cell salvage is superior with respect to postoperative hemoglobin gain and washout of free hemoglobin when compared to centrifugation or ultrafiltration.

    To evaluate the treatment outcome of salvage concurrent radio-chemotherapy for patients with loco-recurrent esophageal cancer after surgery. 50 patients with loco-recurrent squamous-cell cancer after curative esophagectomy were retrospectively analyzed. Patients were treated with radiotherapy (median 60 Gy) combined with chemotherapy consisting of either 5-fluorouracil (5-FU) plus cisplatin (DDP) (R-FP group) or paclitaxel plus DDP (R-TP group). The median follow-up period was 16.0 months. The 1-year and 3-year survival rates were 56% and 14%, respectively. The median progression-free survival (PFS) and overall survival (OS) time was 9.8 and 13.3 months respectively. There was no statistical significance of the PFS of the two groups. The OS (median 16.3 months) in the R-TP group was superior to that in the R-FP group (median: 9.8 months) (p = 0.012). Among the patients who had received ≥60 Gy irradiation dose, the median PFS (10.6 months) and OS (16.3 months) were significantly superior to the PFS (8.7 months) and OS (11.3 months) among those patients did not (all p < 0.05). Grade 3 treatment-related gastritis were observed in 6 (27.3%) and 7 (25%) patients in the R-FP and R-TP group respectively. By univariate survival analysis, the age (<60 years), TP regimen and higher irradiation dose might improve the OS of such patients in present study. For those patients with post-operative loco-recurrent squamous-cell esophageal carcinoma, radiotherapy combined with either FP or TP regimen chemotherapy was an effective salvage treatment. Younger age, treatment with the TP regimen and an irradiation dose ≥60 Gy might improve the patients’ treatment outcome

    Patient blood management is introduced as a new concept that involves the combined use of transfusion alternatives. In elective adult total hip- or knee-replacement surgery patients, the authors conducted a large randomized study on the integrated use of erythropoietin, cell saver, and/or postoperative drain reinfusion devices (DRAIN) to evaluate allogeneic erythrocyte use, while applying a restrictive transfusion threshold. Patients with a preoperative hemoglobin level greater than 13 g/dl were ineligible for erythropoietin and evaluated for the effect of autologous blood reinfusion. Patients were randomized between autologous reinfusion by cell saver or DRAIN or no blood salvage device. Primary outcomes were mean intra- and postoperative erythrocyte use and proportion of transfused patients (transfusion rate). Secondary outcome was cost-effectiveness. In 1,759 evaluated total hip- and knee-replacement surgery patients, the mean erythrocyte use was 0.19 (SD, 0.9) erythrocyte units/patient in the autologous group (n = 1,061) and 0.22 (0.9) erythrocyte units/patient in the control group (n = 698) (P = 0.64). The transfusion rate was 7.7% in the autologous group compared with 8.3% in the control group (P = 0.19). No difference in erythrocyte use was found between cell saver and DRAIN groups. Costs were increased by €298 per patient (95% CI, 76 to 520). In patients with preoperative hemoglobin levels greater than 13 g/dl, autologous intra- and postoperative blood salvage devices were not effective as transfusion alternatives: use of these devices did not reduce erythrocyte use and increased costs.

  14. Salvage robotic radical prostatectomy

    Full Text Available Failure of non-surgical primary treatment for localized prostate cancer is a common occurrence, with rates of disease recurrence ranging from 20% to 60%. In a large proportion of patients, disease recurrence is clinically localized and therefore potentially curable. Unfortunately, due to the complex and potentially morbid nature of salvage treatment, radical salvage surgery is uncommonly performed. In an attempt to decrease the morbidity of salvage therapy without sacrificing oncologic efficacy, a number of experienced centers have utilized robotic assistance to perform minimally invasive salvage radical prostatectomy. Herein, we critically evaluate the existing literature on salvage robotic radical prostatectomy with a focus on patient selection, perioperative complications and functional and early oncologic outcomes. These results are compared with contemporary and historical open salvage radical prostatectomy series and supplemented with insights we have gained from our experience with salvage robotic radical prostatectomy. The body of evidence by which conclusions regarding the efficacy and safety of robotic salvage radical prostatectomy can be drawn comprises fewer than 200 patients with limited follow-up. Preliminary results are promising and some outcomes have been favorable when compared with contemporary open salvage prostatectomy series. Advantages of the robotic platform in the performance of salvage radical prostatectomy include decreased blood loss, short length of stay and improved visualization. Greater experience is required to confirm the long-term oncologic efficacy and functional outcomes as well as the generalizability of results achieved at experienced centers.

    To compare patient outcomes, resource use and costs to the NHS and NHS Blood Transfusion Authority (BTA) associated with cell salvage and alternative methods of minimising perioperative allogeneic blood transfusion. Electronic databases covering the period 1996-2004 for systematic reviews and 1994-2004 for economic evidence. Existing systematic reviews were updated with data from selected randomised controlled trials (RCTs) that involved adults scheduled for elective non-urgent surgery. Any resource use or cost data were extracted for potential use in populating an economic model. Relative risks or weighted mean difference of each outcome for each intervention were assessed, taking into account the number of RCTs included in each outcome and intervention and the presence of any heterogeneity. This allowed indirect comparison of the relative effectiveness of each intervention when the intervention is compared with allogeneic blood transfusion. A decision analytic model synthesised clinical and economic data from several sources, to estimate the relative cost-effectiveness of cell salvage for people undergoing elective surgery with moderate to major expected blood loss. The perspective of the NHS and patients and a time horizon of 1 month were used. The economic model was developed from reviews of effectiveness and cost-effectiveness and clinical experts. Secondary analysis explored the robustness of the results to changes in the timing and costs of cell salvage equipment, surgical procedure, use of transfusion protocols and time horizon of analysis. Overall, 668 studies were identified electronically for the update of the two systematic reviews. This included five RCTs, of which two were cell salvage and three preoperative autologous donation (PAD). Five published systematic reviews were identified for antifibrinolytics, fibrin sealants and restrictive transfusion triggers, PAD plus erythropoietin, erythropoietin alone and acute normovolaemic haemodilution (ANH

    The paper presents analysis of post-operative state of peripheral blood caused by volvulus of the dogs’ stomach. The use of erythrocyte mass in early post-operative period reduces severity of anemia and inflammatory process. The introduction of donor red blood cells reduces severity of action immunosuppressive splenectomy and effects of anesthesia, causing the production of platelets, reticulocytes thus improving reparative processes in the postoperative period.

    2013-09-01

    Recently we suggested a comprehensive blood-sparing approach in pediatric cardiac surgery that resulted in no transfusion in 71 infants (25%), postoperative transfusion only in 68 (24%), and intraoperative transfusion in 149 (52%). We analyzed the effects of transfusion on postoperative morbidity and mortality in the same cohort of patients. The effect of transfusion on the length of mechanical ventilation and intensive care unit stay was assessed using Kaplan-Meier curves. To assess whether transfusion independently determined the length of mechanical ventilation and length of intensive care unit stay, a multivariate model was applied. Additionally, in the subgroup of transfused infants, the effect of the applied volume of packed red blood cells was assessed. The median length of mechanical ventilation was 11 hours (interquartile range, 9-18 hours), 33 hours (interquartile range, 18-80 hours), and 93 hours (interquartile range, 34-161 hours) in the no transfusion, postoperative transfusion only, and intraoperative transfusion groups, respectively (P interquartile range, 1-2 days), 3.5 days (interquartile range, 2-5 days), and 8 days (interquartile range, 3-9 days; P < .00001). The multivariate hazard ratio for early extubation was 0.24 (95% confidence interval, 0.16-0.35) and 0.37 (95% confidence interval, 0.25-0.55) for the intraoperative transfusion and postoperative transfusion only groups, respectively (P < .00001). In addition, the cardiopulmonary time, body weight, need for reoperation, and hemoglobin during cardiopulmonary bypass affected the length of mechanical ventilation. Similar results were obtained for the length of intensive care unit stay. In the subgroup of transfused infants, the volume of packed red blood cells also independently affected both the length of mechanical ventilation and the length of intensive care unit stay. The incidence and volume of blood transfusion markedly affects postoperative morbidity in pediatric cardiac surgery. These

    Full Text Available Abstract Background Surgery after (chemoradiation (RCTX/RTX is felt to be plagued with a high incidence of wound healing complications reported to be as high as 70%. The additional use of vascularized flaps may help to decrease this high rate of complications. Therefore, we examined within a retrospective single-institutional study the peri--and postoperative complications in patients who underwent surgery for salvage, palliation or functional rehabilitation after (chemoradiation with regional and free flaps. As a second study end point the Karnofsky performance status (KPS was determined preoperatively and 3 months postoperatively to assess the impact of such extensive procedures on the overall performance status of this heavily pretreated patient population. Findings 21 patients were treated between 2005 and 2010 in a single institution (17 male, 4 female for salvage (10/21, palliation (4/21, or functional rehabilitation (7/21. Overall 23 flaps were performed of which 8 were free flaps. Major recipient site complications were observed in only 4 pts. (19% (1 postoperative haemorrhage, 1 partial flap loss, 2 fistulas and major donor site complications in 1 pt (wound dehiscence. Also 2 minor donor site complications were observed. The overall complication rate was 33%. There was no free flap loss. Assessment of pre- and postoperative KPS revealed improvement in 13 out of 21 patients (62%. A decline of KPS was noted in only one patient. Conclusions We conclude that within this (chemoradiated patient population surgical interventions for salvage, palliation or improve function can be safely performed once vascularised grafts are used.

    Correction of craniosynostosis can result in blood loss when the patient already has physiologic anemia. The aim of this study was to determine whether patients benefit from early blood transfusion and whether the timing of blood transfusion affects metabolic disturbances and the postoperative course. In this retrospective review, 71 patients who underwent open calvarial vault remodeling for correction of craniosynostosis were separated into 2 groups according to whether they received blood transfusions early (within the first 30 minutes of surgery) or later (after the first 30 minutes of surgery). Patients were further separated into nonsyndromic and syndromic cohorts. Tracked variables included hemoglobin, hematocrit, arterial blood gas values, lactate level, length of stay, estimated blood loss, and amount of blood transfused in the operating room, amount transfused postoperatively, and total amount transfused.Among all patients, the early transfusion group had a higher hemoglobin nadir overall and received less postoperative blood. Within the nonsyndromic cohort, the early transfusion group had a higher estimated blood loss and received more transfused blood. In the syndromic cohort, the early transfusion group had a hemoglobin nadir that was significantly higher than in the late transfusion group and a lower estimated blood loss, shorter pediatric intensive care unit stay, and less postoperative blood transfused. Syndromic patients also received significantly more blood overall. For syndromic patients undergoing open calvarial vault remodeling, transfusion within the first 30 minutes of surgery should be considered.

    The safe use of intraoperative blood salvage (IBS) in cancer surgery remains controversial. Here, we investigated the killing effect of cisplatin combined with hyperthermia on human hepatocarcinoma (HepG2) cells and erythrocytes from IBS in vitro. HepG2 cells were mixed with concentrated erythrocytes and pretreated with cisplatin (50, 100, and 200 μg/ml) alone at 37 °C for 60 min and cisplatin (25, 50, 100, and 200 μg/ml) combined with hyperthermia at 42 °C for 60 min. After pretreatment, the cell viability, colony formation and DNA metabolism in HepG2 and the Na(+)-K(+)-ATPase activity, 2,3-diphosphoglycerate (2,3-DPG) concentration, free hemoglobin (Hb) level, osmotic fragility, membrane phosphatidylserine externalization, and blood gas variables in erythrocytes were determined. Pretreatment with cisplatin (50, 100, and 200 μg/ml) combined with hyperthermia (42 °C) for 60 min significantly decreased HepG2 cell viability, and completely inhibited colony formation and DNA metabolism when the HepG2 cell concentration was 5×10(4) ml(-1) in the erythrocyte (P2,3-DPG level, phosphatidylserine externalization, and extra-erythrocytic free Hb were significantly altered by hyperthermia plus high concentrations of cisplatin (100 and 200 μg/ml) (P0.05). In conclusion, pretreatment with cisplatin (50 μg/ml) combined with hyperthermia (42 °C) for 60 min effectively eliminated HepG2 cells from IBS but did not significantly affect erythrocytes in vitro.

    It is recommended that arteriovenous fistula (AVF) blood flow should be more than 425 ml/min before cannulation. However, the relationship between preoperative radial artery flow (RAF) and postoperative AVF blood flow has still not been examined. Sixty-one patients with end-stage kidney disease (ESKD) were examined. They had an AVF prepared at Juntendo University Hospital from July 2006 through August 2007. Preoperative RAF and postoperative AVF blood flows were measured by ultrasonography. AVF blood flow gradually increased after the operation. AVF blood flow was significantly correlated with preoperative RAF. When preoperative RAF exceeded 21.4 ml/min, AVF blood flow rose to more than 425 ml/min. The postoperative AVF blood flow in the group with RAF of more than 20 ml/min was significantly higher than that in those with less than 20 ml/min. Preoperative RAF of less than 20 ml/min had a significantly high risk of primary AVF failure within 8 months compared with that of more than 20 ml/min. It appears that measurement of RAF by ultrasonography is useful for estimating AVF blood flow postoperatively and can predict the risk of complications in ESKD patients.

    The question of independent association between allogeneic blood transfusion (ABT) and postoperative complications in cancer surgeries has been controversial and remains so. In metastatic spine tumor surgery (MSTS), previous studies investigated the influence of ABT on survival, but not on postoperative complications. We aimed to evaluate the influence of perioperative ABT on postoperative complications and infections in patients undergoing MSTS. This retrospective study included 247 patients who underwent MSTS at a single tertiary institution between 2005 and 2014. The outcome measures were postoperative complications and infections within 30 days after MSTS. Multivariate logistic regression analyses were performed to assess influence of blood transfusion on the outcomes after adjusting for potential confounders. Of 247 patients, 133 (54%) received ABT with overall median (range) of 2 (0-10) units. The adjusted odds of developing any postoperative complication was 2.27 times higher in patients with transfusion (95% confidence interval [CI], 1.17-4.38; p = 0.01) and 1.24 times higher odds per every unit increase in blood transfusion (95% CI, 1.05-1.46; p blood transfusion also increased the odds of having overall postoperative infections (odds ratio, 3.58; 95% CI, 1.15-11.11; p = 0.02) and there were 1.24 times higher odds per every unit increase in transfusion (95% CI, 1.01-1.54; p = 0.04). This study adds evidence to the literature implicating ABT to be influential on postoperative complications and infections in patients undergoing MSTS. Appropriate blood management measures should, therefore, be given a crucial place in the care of these patients so as to reduce any putative effect of blood transfusion. © 2017 AABB.

    Full Text Available Introduction: Blood transfusion is common in patients undergoing cardiac surgery. Aim: Our goal was to investigate the association between blood transfusions in the early postoperative period and complications during Cardiac Intensive Care Unit (CICU stay. Methods: Retrospectively analysis in 874 patients who underwent isolated coronary artery bypass grafting, valve surgery or combined procedures. Patients were allocated to two groups according to the presence (Group A or absence (Group B of blood transfusion during extracorporeal circulation, surgery and CICU stay. Two hundred thirty four patients with preexisting hepatic or blood diseases, atrial fibrillation, emergent surgery or those received autologous blood transfusions were excluded prior to the study. Morbidity was defined as prolonged postoperative mechanical ventilation, mechanical ventilation>7hours, reintubation, use of non-invasive ventilation, postoperative atrial fibrillation and length of hospital stay. Statistical analysis was carried out using Chi-square, Student’s t-test, Relative Risk (RR and logistic regression with statistical significance set at p7 hours (p 7 hours (p<0.01. Conclusions: Blood transfusions seem to associate with certain complications in cardiac surgery patients.

    Full Text Available Purpose To assess the oncologic and functional outcomes of salvage renal surgery following failed primary intervention for RCC. Materials and Methods We performed a retrospective review of patients who underwent surgery for suspected RCC during 2004-2012. We identified 839 patients, 13 of whom required salvage renal surgery. Demographic data was collected for all patients. Intraoperative and postoperative data included ischemic duration, blood loss and perioperative complications. Preoperative and postoperative assessments included abdominal CT or magnetic resonance imaging, chest CT and routine laboratory work. Estimated glomerular filtration rate (eGFR was calculated according to the Modification of Diet in Renal Disease equation. Results The majority (85% of the patients were male, with an average age of 64 years. Ten patients underwent salvage partial nephrectomy while 3 underwent salvage radical nephrectomy. Cryotherapy was the predominant primary failed treatment modality, with 31% of patients undergoing primary open surgery. Pre-operatively, three patients were projected to require permanent post-operative dialysis. In the remaining 10 patients, mean pre- and postoperative serum creatinine and eGFR levels were 1.35 mg/dL and 53.8 mL/min/1.73 m2 compared to 1.43 mg/dL and 46.6 mL/min/1.73 m2, respectively. Mean warm ischemia time in 10 patients was 17.4 min and for all patients, the mean blood loss was 647 mL. The predominant pathological stage was pT1a (8/13; 62%. Negative surgical margins were achieved in all cases. The mean follow-up was 32.9 months (3.5-88 months. Conclusion While salvage renal surgery can be challenging, it is feasible and has adequate surgical, functional and oncological outcomes.

    1997-09-01

    We hypothesized that the success of postoperative blood conservation after acute normovolaemic haemodilution (NVHD) is influenced by the extent of intraoperative bleeding and surgical trauma, and the timing of autologous blood transfusion. As total knee replacement is associated with minimal intraoperative but extensive postoperative blood loss, this procedure is ideally suited to acute NVHD. Therefore, to test our hypothesis, 30 patients undergoing elective total knee replacement were enrolled in a prospective, randomized, controlled study. In groups NVHD-2 and NVHD-6, before induction of anaesthesia patients were bled to a target packed cell volume (PCV) of 28-30%, and in the post-anaesthesia care unit autologous blood was transfused over a 2-h period terminating after operation at 2 and 6 h, respectively. In the control group, NVHD was not performed. After operation, platelets, fibrinogen, prothrombin and partial thromboplastin time, and liver function, urea and electrolytes were measured and compared with preoperative baseline values. Significantly (P conservation strategy. However, there was no difference in allogeneic blood administration between the two NVHD groups. Coagulation and liver function, and urea and electrolyte concentrations were unaffected by treatment.

    2015-09-01

    Because of uncertainty regarding the reliability of perioperative blood pressures and traditional notions downplaying the role of anesthesiologists in longitudinal patient care, there is no consensus for anesthesiologists to recommend postoperative primary care blood pressure follow-up for patients presenting for surgery with an increased blood pressure. The decision of whom to refer should ideally be based on a predictive model that balances performance with ease-of-use. If an acceptable decision rule was developed, a new practice paradigm integrating the surgical encounter into broader public health efforts could be tested, with the goal of reducing long-term morbidity from hypertension among surgical patients. Using national data from US veterans receiving surgical care, we determined the prevalence of poorly controlled outpatient clinic blood pressures ≥140/90 mm Hg, based on the mean of up to 4 readings in the year after surgery. Four increasingly complex logistic regression models were assessed to predict this outcome. The first included the mean of 2 preoperative blood pressure readings; other models progressively added a broad array of demographic and clinical data. After internal validation, the C-statistics and the Net Reclassification Index between the simplest and most complex models were assessed. The performance characteristics of several simple blood pressure referral thresholds were then calculated. Among 215,621 patients, poorly controlled outpatient clinic blood pressure was present postoperatively in 25.7% (95% confidence interval [CI], 25.5%-25.9%) including 14.2% (95% CI, 13.9%-14.6%) of patients lacking a hypertension history. The most complex prediction model demonstrated statistically significant, but clinically marginal, improvement in discrimination over a model based on preoperative blood pressure alone (C-statistic, 0.736 [95% CI, 0.734-0.739] vs 0.721 [95% CI, 0.718-0.723]; P for difference 1 of 4 patients (95% CI, 25

    The aim of the study was to evaluate whether valproate (VPA) increases the risk of bleeding complications in patients undergoing brain tumor surgery. A retrospective chart review of 85 patients operated on between January and December 2005 was performed. 19 patients received VPA, 22 patients were given other anti-epileptic drugs (AEDs), 44 patients received no AEDs. Data analyzed included intraoperative blood loss, transfusion, important comorbidity factors and concomitant diseases. Preoperative and postoperative laboratory data included hemoglobin, hematocrit, fibrinogen, platelet count, INR, prothrombin time, partial thromboplastin time and RBC count. The tumor volume was evaluated by preoperative MRI and CT scans of the brain. All 85 patients underwent a native CT scan of the brain on the first day after the operation. The volume of the resection cavity and the volume of blood were documented. We could show that the volume of the tumor had a significant effect on the amount of blood in the tumor cavity, whereas VPA medication had no effect. In our dataset, we found that tumor size had a significant effect on postoperative blood volume. In contrast, no serious bleeding complications occurred in the patients receiving VPA. Therefore, the present study does not provide any evidence for the need to discontinue VPA medication prior to and during surgery.

    The objective is to study the effects of flurbiprofen axetil (FA) with fentanyl together in postoperative controlled intravenous analgesia (PCIA) on pain intensity, cytokine levels in peripheral blood and adverse reactions of thoracotomy patients. Fifty thoracotomy patients were divided into a FA and a control group, each with 25 cases. Postoperative analgesia was administered in the two groups using PCIA. The pressing times of analgesia pump, the visual analog scale (VAS) scores during resting and coughing at 2, 6, 24, 48, 72 h after surgery and the incidence of adverse drug reactions were recorded. Levels of IL-1β, IL-6, IL-8, IL-2, and TNF-α in peripheral blood were determined before the administration of FA (T0), and at 24 h (T1), 48 h (T2), 72 h (T3) after surgery. The analgesia pump pressing times in the FA group was less than that of the control group. The VAS scores during resting and coughing at 2, 6, 24, 48, 72 h after surgery, were statistically less than those of control group. The incidence rate of nausea and vomiting was insignificantly different between the two groups. Administration of FA together with PCIA in thoracotomy patients can improve postoperative analgesia.

    Salvage esophagectomy is the sole curative intent treatment for patients with persistent or recurrent locoregional disease after definitive chemoradiotherapy (CRT) for esophageal carcinoma. However, salvage esophagectomy is a very high-risk operation, and airway necrosis is a fatal complication. Between 1997 and 2007, 49 patients with thoracic esophageal cancer underwent salvage esophagectomy after definitive CRT. We retrospectively compared patients with and without airway necrosis, and investigated operative procedures related to airway necrosis. Airway necrosis occurred in five patients (10.2%), of four patients (80%) died during their hospitalization. Airway necrosis seemed to be closely related to operative procedures, such as resection of bronchial artery and cervical and subcarinal lymph node dissection. Bronchogastric fistula following necrosis of gastric conduit occured in 2 patients reconstructed through posterior mediastinal route. Airway necrosis is a highly lethal complication after salvage esophagectomy. It is important in salvage esophagectomy to take airway blood supply into consideration sufficiently and to reconstruct through retrosternal route to prevent bronchogastric fistula. (author)

  18. A Novel Centrifugation Method Using a Cell Salvage Device Offers an Alternative to the Use of Leukocyte-Depleting Filters for Autologous Blood Transfusions.

    Autotransfusion protocols often use the use of costly filters, such as leukocyte-depleting filters (LDFs), to minimize reinfusion of activated leukocytes and inflammatory mediators associated with reperfusion injury (RI). LDFs are used extensively in hospital settings; however, they represent an additional capital expenditure for hospitals, as well as a constraint on the reinfusion rate of blood products for health-care providers. We compared a commonly used LDF to a novel centrifugation method employing a widely used cell salvage device. Complete blood counts and enzyme-linked immunosorbent assays (ELISAs) measuring tumor necrosis factor-α (TNF-α) and interleukin-2 (IL-2) were performed to compare the efficacy of these methodologies. The LDF removed, on average, 94% of all leukocytes, including 96% of neutrophils. The centrifugation method removed, on average, 89% of all leukocytes, including 91% of neutrophils and resulted in a highly concentrated red blood cell product. Our results suggest both methods offer equivalent leukocyte reduction. TNF-α was also comparably reduced following our novel centrifugation method and the LDF method and IL-2 levels were undetectable in all samples. These results indicate our novel centrifugation method may preclude the need for a LDF during select autotransfusion applications.

    Postoperative calcium management is challenging following pediatric thyroidectomy given potential limitations in self-reporting symptoms and compliance with phlebotomy. A protocol was created at our tertiary children's institution utilizing intraoperative parathyroid hormone (PTH) levels to guide electrolyte management during hospitalization. The objective of this study was to determine the effect of a new thyroidectomy postoperative management protocol on two primary outcomes: (1) the number of postoperative calcium blood draws and (2) the length of hospital stay. Institutional review board approved retrospective study (2010-2016). Consecutive pediatric total thyroidectomy and completion thyroidectomy ± neck dissection cases from 1/1/2010 through 8/5/2016 at a single tertiary children's institution were retrospectively reviewed before and after initiation of a new management protocol. All cases after 2/1/2014 comprised the experimental group (post-protocol implementation). The pre-protocol control group consisted of cases prior to 2/1/2014. Multivariable linear and Poisson regression models were used to compare the control and experimental groups for outcome measure of number of calcium lab draws and hospital length of stay. 53 patients were included (n = 23, control group; n = 30 experimental group). The median age was 15 years. 41 patients (77.4%) were female. Postoperative calcium draws decreased from a mean of 5.2 to 3.6 per day post-protocol implementation (Rate Ratio = 0.70, p Hypocalcemia was also associated with a longer mean length of stay of 2.41 days compared to 1.60 days in patients who did not develop hypocalcemia (p < .01). The number of calcium blood draws was significantly reduced after introduction of a standardized protocol based on intraoperative PTH levels. The hospital length of stay did not change. Adoption of a standardized postoperative protocol based on intraoperative PTH levels may reduce the number of blood draws

    Full Text Available ObjectiveTo investigate whether blood lipid control can delay the progression of asymptomatic gallstones and reduce the risk of cholecystectomy in patients with gallstones and hyperlipidemia, as well as the influence of hyperlipidemia on postoperative pain after cholecystectomy. MethodsA total of 153 patients with asymptomatic gallstones and hyperlipidemia who underwent physical examination from February 2013 to February 2015 were enrolled and randomly divided into experimental group with 72 patients and control group with 81 patients. The patients in the experimental group were given blood lipid control via diet, exercise, and drugs, and according to fasting triglyceride (TG and total cholesterol (TC after 3 months, these patients were further divided into normal blood lipid group with 47 patients and abnormal blood lipid group with 25 patients. All the patients were followed up for 2 years with an interval of 3 months. The surgical indications for laparoscopic cholecystectomy were persistent pain in the gallbladder or more than 3 times of gallbladder discomfort within the past one month. A subgroup analysis was performed based on the number and size of gallstones to evaluate the risk of cholecystectomy. A numerical pain scale was used to assess the improvement in pain during hospitalization and at 3 and 6 months after surgery. The t-test was used for comparison of continuous data between two groups; a one-way analysis of variance was used for comparison between three groups, and the Bonferroni test was used for further comparison between any two groups. The chi-square test was used for comparison of categorical data between groups. ResultsThe normal blood lipid group had a significantly lower rate of cholecystectomy than the abnormal blood lipid group and the control group (23.4% vs 68.8%/70.4%, χ2=2772, P<0.01. The patients in the normal blood lipid group had moderate pain during hospitalization, while those in the abnormal blood lipid

After an initial dose of 20 ml plain bupivacaine 0.5%, a continuous epidural infusion of bupivacaine 0.5% (8 ml/hr) was given for 16 hours...... for postoperative pain relief. The epidural blood flow was measured by a local 133Xe clearance technique in which 15-35 MBq 133Xe diluted in 1 ml saline was injected through the epidural catheter on the day before surgery (no bupivacaine), 30 minutes after the initial dose of bupivacaine on the morning before...... surgery, and 8, 12, and 16 hours later during the continuous infusion. Initial blood flow was 6.0 +/- 0.7 ml/min per 100 g tissue (mean +/- SEM). After epidural bupivacaine, blood flow increased in all seven patients to 7.4 +/- 0.7 ml (P less than 0.02).

    Full Text Available One possible area of intervention to prevent postoperative delirium (PD is intraoperative blood pressure management. However, the relationship between intraoperative blood pressure and PD is unclear. A secondary analysis of a RCT study examining the PD risk over the range of absolute intraoperative mean arterial blood pressure (MAP readings and the corresponding relative changes from preoperative baseline level was performed to determine the role of MAP on PD.Nonparametric locally weighted quadratic polynomial smoothing (LOESS regression explored the pattern of PD risk at postoperative day 2 as a function of mean surgery MAP (msMAP and percent change of msMAP from baseline in 103 elderly hip fracture patients. Segment-linear logistic regression models were then constructed to determine the odds ratios (OR of PD over the observed range of these msMAP measures, adjusting for potential confounds.Twenty-three patients (22% developed PD on day 2. LOESS regression revealed a j-shaped association between absolute levels of msMAP and PD risk. When msMAP was ≥80 mmHg, higher msMAP imparted greater PD risk (OR = 2.28 per 10 mmHg msMAP increase; 95% CI: 1.11-4.70, while higher msMAP was associated with lower PD risk (OR = 0.19 per 10 mmHg increase; CI: 0.05-0.76 if msMAP was <80 mmHg. There was no statistically significant relationship between PD risk and average percent change from baseline in these msMAP measures.In elderly hip fracture patients, both very high and very low levels of msMAP were associated with significantly increased risk of PD.

    This study was performed to test the effectiveness of topical tranexamic acid (TXA) in reducing blood loss in pelvic hemiarthoplasty surgeries compared with intravenous TXA, regarding the incidence of thromboembolic complications (deep vein thrombosis [DVT], pulmonary embolism (PE) and cerebrovascular stroke [CVS]). After obtaining institutional ethical approval 60 patients divided into three groups. Group A: Received intravenous TXA Group B: Received topical TXA Group C: Control group (placebo saline). All patients were received general anesthesia and post-operative bleeding, immediate and 24 h post-operatively, hemoglobin concentration, hematocrit, platelets and coagulation profile (prothrombin time, activated partial thromboplastin time and international normalized ratio) baseline, immediate and 24 h post-operatively. Thromboelastography was recorded baseline, immediate and 24 h post-operatively. Incidence of DVT, PE and CVS was recorded. There was statistical significant elevation hemoglobin concentration and hematocrit in both Groups A and B, significant increase in blood loss in Group C, significant increase in number of patients receiving blood in Group C, there was a significant decrease in "r" and "k" times and a significant increase in maximum amplitude and α-angle in Group A, statistically significant increase in the incidence of thromboembolic events in the form of DVT, PE and CVS in Group A. Topical TXA is effective in decreasing post-operative blood loss with possible side-effects of this route of administration.

    BACKGROUND Postoperative cognitive dysfunction (POCD) is a postoperative complication after surgery and anesthesia. Whether ABO blood types are associated with POCD in elderly patients undergoing unilateral total hip arthroplasty surgery in China is unclear. MATERIAL AND METHODS Firstly, 142 elderly patients were divided into a POCD group and a non-POCD group according to the Mini Mental State Examination (MMSE) scores and ABO blood types were analyzed. Secondly, according to ABO blood type, the selected 226 patients were divided into 4 groups: type A group, type B group, type AB group, and type O group. Then, all patients completed the MMSE before and after surgery. Finally, the occurrence of POCD was recorded and related data were analyzed. RESULTS Firstly, there was a significant difference in both groups in terms of distribution of ABO blood types, and elderly patients who developed POCD were more likely to have type A blood and less likely to have type O blood. Secondly, compared with elderly patients with type A blood, those with type O had higher MMSE scores on the first day and the seventh day after surgery. Finally, the risk of developing POCD was significantly higher in patients with type A blood and on the first day and the seventh day after surgery the risk of developing POCD was significantly lower in patients with type O blood. CONCLUSIONS Elderly patients with type A blood have higher risk of developing early POCD and those with type O blood have less risk of developing early POCD.

    Full Text Available Introduction. Microcirculation plays an important role in early postoperative period in colorectal cancer patients. At the same time the question connected with studying of rheological properties of blood as one of microcirculation indicators in literature it studied insufficiently.Materials and methods. We studied rheological properties of blood in 30 patients operated for bowel obstruction caused by right colon cancer. 17 (56,7 % patients were male, 13 (43,3 % – female. Average age was 57 ± 3 years. Time from the moment of manifestation of the first clinical signs before admission to a hospital and the beginnings of carrying out medical and diagnostic actions was 12 ± 0,5 h. The stage of a disease was T3N0–1M0. The group of comparison consisted of 20 healthy volunteers of the same age. Changes of a rheology of blood were measured by means of the accounting of viscosity of blood, change of an index of deformation and aggregation of erythrocytes. Studying of viscosity of blood was carried out by means of the rotational viscometer at shift speeds: 200; 100; 150; 50 and 20 MPas. Measures were conducted at the time of receipt, on the first, third, fifth, seventh and tenth postoperative day.Results. In patients with bowel impassability at the time of receipt the increase in indicators of viscosity of blood is noted at all speeds of the shift, analyzed indicators increase by the third postoperative day, decrease on the seventh and are partially restored for the tenth postoperative days. Complications developed in 16,6 % of cases, in all cases – pneumonia. By comparison of the obtained laboratory data to a clinical picture it is established that complications developed on 3–5th postoperative days.

    The reductions of perioperative blood loss and inflammatory response are important in total knee arthroplasty. Tranexamic acid reduced blood loss and the inflammatory response in several studies. However, the effect of epinephrine administration plus tranexamic acid has not been intensively investigated, to our knowledge. In this study, we evaluated whether the combined administration of low-dose epinephrine plus tranexamic acid reduced perioperative blood loss or inflammatory response further compared with tranexamic acid alone. This randomized placebo-controlled trial consisted of 179 consecutive patients who underwent primary total knee arthroplasty. Patients were randomized into 3 interventions: Group IV received intravenous low-dose epinephrine plus tranexamic acid, Group TP received topical diluted epinephrine plus tranexamic acid, and Group CT received tranexamic acid alone. The primary outcome was perioperative blood loss on postoperative day 1. Secondary outcomes included perioperative blood loss on postoperative day 3, coagulation and fibrinolysis parameters (measured by thromboelastography), inflammatory cytokine levels, transfusion values (rate and volume), thromboembolic complications, length of hospital stay, wound score, range of motion, and Hospital for Special Surgery (HSS) score. The mean calculated total blood loss (and standard deviation) in Group IV was 348.1 ± 158.2 mL on postoperative day 1 and 458.0 ± 183.4 mL on postoperative day 3, which were significantly reduced (p 0.05). The combined administration of low-dose epinephrine and tranexamic acid demonstrated an increased effect in reducing perioperative blood loss and the inflammatory response compared with tranexamic acid alone, with no apparent increased incidence of thromboembolic and other complications.

    As the use of concurrent chemoradiotherapy (CCRT) is becoming more widespread, with numerous facilities performing it to maintain function and form, the number of cases requiring salvage surgery is also increasing. We investigated the postoperative prognosis of patients who experienced complications during salvage surgery after CCRT. Subjects were 27 patients who underwent salvage surgery following CCRT at our department during the 7-year period between January 2005 and December 2011. We selected all cases of salvage surgery, comprising neck dissections, total laryngectomies, partial laryngectomies, esophageal resections, and reconstructive surgeries, for analysis. The results were favorable, with a complication rate during salvage surgery after CCRT of 14.8% and a survival rate of 77.8%. Although it is difficult to compare these complications and outcome findings with available reports on salvage surgery without CCRT, it is believed complications can arise in approximately half of the cases. Thus, surgeons should be cognizant of the potential for serious complications, which are sometimes unexpected. Different from our findings, the prognosis following salvage surgery is generally not thought to be favorable and therefore care should be taken to detect recurrence and provide treatment early in salvage surgery cases.

Material and methods. Primary THA was performed in 51 RA pts with hip damage (49 female, 2 male aged from 26 to 68 years. 42 THA were performed with “Endosystems and Implants” (ESI endoprosthesis, and 21 — with “Mathys” endoprosthesis. The pts were divided into two groups. Standard infusion-transfusion therapy with donor blood components was performed in group 1 pts (n=26 to compensate blood loss in EPP. In group 2 pts (n=25 drainage blood reinfusion was done with active aspiration system Handy Vac TM ATS (Unomedical. Group 1 pts had more prominent circulatory and neurologic disturbances in EPP: hypodynamic variant of circulation with elevation of peripheral vascular resistance till 5-7 day of postoperative period, prominent hypersympathicotonia and a large number of posttransfusion reactions. Evaluation of hemodynamic and vegetative disturbances showed advantage of blood loss compensation and vegetative disturbances normalization with drainage blood reinfusion in EPP after THA in comparison with standard pts management.

    The patient was a 74-year-old man. A total laryngectomy was performed due to recurrence of laryngeal cancer after chemoradiotherapy (CRT). Postoperatively, a pharyngocutaneous fistula developed and patch-graft reconstruction using a pectoral major musculocutaneous flap was planned. However, due to expansion of the necrotic area, we needed to perform tubular reconstruction. Nevertheless, infection and pus discharge were observed and a second surgery was performed. Resection and reconstruction at the neck were considered impossible because advanced necrosis was seen at the cervical esophageal stump, and the operative procedure was changed to esophageal resection, gastric pull-up and free jejunum transfer. Although leakage was found at the jejunum-gastric anastomosis site by fluoroscopy on the 14th postoperative day, it disappeared through conservative therapy. In addition, oral ingestion was begun on the 28th postoperative day. At 6 months after the surgery, the patient was able to regularly intake food and no constriction of the tracheostoma was seen. In this case, unexpected expansion of the necrotic area was a significant problem. As for the causes, diminished blood flow to the esophagus due to total thyroidectomy and bilateral paratracheal lymph node dissection, and infection in the surrounding area, along with remarkable tissue damage with CRT were considered possible. In salvage surgery, attention will be necessary in evaluating necrotic range and selection of appropriate reconstructive procedure. (author)

    Few reports have covered salvage surgery after radiotherapy, especially with chemotherapy for oral, oropharyngeal, and hypopharyngeal squamous cell carcinoma. The feasibility of salvage surgery is unclear. We analyzed postoperative complications and prognosis after salvage surgery for local recurrence after definitive radiotherapy. Subjects were 37 patients with oral, oropharyngeal, and hypopharyngeal squamous cell carcinoma treated from 1994 to 2003. Of these, 14 (37.8%) had postoperative complications. The complication rate was significantly high in the reconstructive operation group (p=0.031) and the chemotherapy group (p=0.049). The 5-year overall survival rate after salvage surgery was 70.7%. Although there was no significant improvement, the prognosis was good in early-stage groups with primary tumors. We found that salvage surgery after definitive radiotherapy was effective for recurrent oral, oropharyngeal, and hypopharyngeal squamous cell carcinoma. We stress the need to pay attention to postoperative complications in reconstructive operation and chemotherapy groups. (author)

    Objective: Homologous blood transfusion after open heart surgery puts a tremendous load on the blood banks. This prospective randomized study evaluates the efficacy of infusing back residual cardiopulmonary bypass (CPB) circuit i.e., pump blood as a means to reduce homologous transfusion after coronary artery bypass surgery (CABG) and whether its use increases postoperative drainage. Materials and Methods: Sixty-seven consecutive patients who underwent elective CABGs under CPB were randomized into 2 groups: (1) cases where residual pump blood was used and (2) controls where residual pump blood was not used. Patients were monitored for hourly drainage on the day of surgery and the 1st postoperative day and the requirements of homologous blood and its products. Data were matched regarding change in Hemoglobin, Packed Cell Volume and coagulation parameters till 1st postoperative day. All cases were followed up for three years. Results: There was a marginal reduction in bleeding pattern in the early postoperative period in the cases compared to controls. The requirement of homologous blood and its products were also reduced in the cases. Conclusions: The use of CPB circuit blood is safe in the immediate postoperative period. The requirement of homologous blood transfusion can come down if strict transfusion criteria are maintained. PMID:20041077

    Assess the effectiveness of priming the extracorporeal circulation system with albumin-mannitol combined with ultrafiltration during extracorporeal circulation to reduce post-operative bleeding and transfusion requirements in heart surgery, as well as its impact on the fluid balance, coagulation and hematocrit parameters, re-operation for bleeding, ICU, and hospital length of stay. A total of 134 patients scheduled for heart surgery were randomized to receive Ringer's lactate 1,500mL in the priming reservoir (group C), or mannitol 20% 250mL, albumin 20% 150mL and Ringer's lactate 1,100mL combined with ultrafiltration (group T). Bleeding volume, transfusions, fluid balance, coagulation, and hematology parameters were determined until 48h in the post-operative period. There was a reduction of postoperative bleeding in group T, 1,165±789mL vs 992±662mL (P=.17), and red blood cell concentrate transfusions, 694±843mL vs 413±605mL (P=.03). Intra-operative and post-operative fluid balance was significantly less positive in group T, with an overall balance of 2,292±2,152mL vs 5,388±2,834mL (P<.001). There were higher values of hemoglobin and hematocrit, intraoperative (P<.001), on admission to ICU (P=.001), and at 6h (P=.05) in group T, and lower INR at 6h (P=.01) and 24h (P=.02). Re-operation rate and length of stay in ICU were higher in group C, but not statiscally significant. The priming of extracorporeal reservoir with mannitol, albumin, and Ringer's lactate, combined with ultrafiltration, significantly improves intra- and post-operative fluid balance, resulting in a reduction in blood transfusions, with no significant decrease in post-operative bleeding, re-operation bleeding rate, and length of stay in the ICU.

Recently, intra-articular tranexamic acid (IA-TXA application has become a popular method for perioperative blood loss (PBL reduction in total knee replacement (TKR. Nevertheless, through our knowledge, no previous studies had shown the correlation perioperative factors and the risk of excessive PBL or need of blood transfusion (BT after IA-TXA. Materials and Methods. A retrospective study was conducted in patients underwent 299 primary TKRs, using IA-TXA, during 2-year period (2013-2014. Patient’s characteristic and perioperative data were reviewed and collected. PBL was measured as total hemoglobin loss (THL, estimated total blood loss (ETBL, and drainage volume per kg (DV/kg. Excessive PBL was defined as PBL that exceeded 90th percentile. Results. From multivariate analysis, low preoperative hemoglobin (Hb level and body mass index (BMI were the significant predictors of postoperative BT (p<0.0001 and 0.003, resp.. Excessive THL significant associated with preoperative Hb (p<0.0001. Excessive ETBL significantly associated with preoperative Hb, height, preoperative range-of-motion, and creatinine clearance (p<0.05 all. Low BMI and large prosthesis size were the significant predictors of excessive DV/kg (p=0.0001 and 0.002, resp.. Conclusions. Low preoperative Hb and BMI were the significant risks of postoperative transfusion after TKR with IA-TXA. Moreover, multiple perioperative factors could result in higher PBL.

    Severely anemic patients for whom blood transfusion is not an option provide highly valuable information on risks of anemia and alternative management strategies. This is a retrospective study of consecutive patients at least 18 years old who could not be transfused, had surgery at a patient blood management center between 2003 and 2012, and had at least one hemoglobin (Hb) measurement of not more than 8 g/dL during the postoperative period. The primary outcome measure was mortality, occurring anytime in the period after the surgery until discharge or 30th day after the surgery, whichever was sooner. Postoperative morbidities included the occurrence of any of sepsis, pneumonia, myocardial infarction, deep wound infection, congestive heart failure, and arrhythmia. A total of 293 patients (including 288 who self-identified as "Jehovah's Witness") were eligible and enrolled. The mean ± SD age of the patients was 61.5 ± 16.9 years and 74.1% were female. Overall mortality rate was 8.2% (95% confidence interval [CI], 5%-11.3%). Unadjusted odds ratio (OR) of death per each 1 g/dL decrease in the nadir postoperative Hb was 2.04 (95% CI, 1.52-2.74); OR of death after adjustment for other significant factors (urgency, American Society of Anesthesiology score, and age) was 1.82 (95% CI, 1.27-2.59). Our study confirms the previously reported low risk of mortality in upper nadir Hb ranges of 7 to 8 g/dL and much higher risk in lower ranges, albeit the number of patients reaching extremely low Hb levels were lower than previous report, possibly suggestive of improved management strategy of these patients. © 2014 AABB.

    The threat of lower limb loss is seen commonly in severe crush injury, cancer ablation, diabetes, peripheral vascular disease and neuropathy. The primary goal of limb salvage is to restore and maintain stability and ambulation. Reconstructive strategies differ in each condition such as: Meticulous debridement and early coverage in trauma, replacing lost functional units in cancer ablation, improving vascularity in ischaemic leg and providing stable walking surface for trophic ulcer. The decision to salvage the critically injured limb is multifactorial and should be individualised along with laid down definitive indications. Early cover remains the standard of care, delayed wound coverage not necessarily affect the final outcome. Limb salvage is more cost-effective than amputations in a long run. Limb salvage is the choice of procedure over amputation in 95% of limb sarcoma without affecting the survival. Compound flaps with different tissue components, skeletal reconstruction; tendon transfer/reconstruction helps to restore function. Adjuvant radiation alters tissue characters and calls for modification in reconstructive plan. Neuropathic ulcers are wide and deep often complicated by osteomyelitis. Free flap reconstruction aids in faster healing and provides superior surface for offloading. Diabetic wounds are primarily due to neuropathy and leads to six-fold increase in ulcerations. Control of infections, aggressive debridement and vascular cover are the mainstay of management. Endovascular procedures are gaining importance and have reduced extent of surgery and increased amputation free survival period. Though the standard approach remains utilising best option in the reconstruction ladder, the recent trend shows running down the ladder of reconstruction with newer reliable local flaps and negative wound pressure therapy.

    Blood conservation techniques are being increasingly used because of the increased cost and lack of availability of allogeneic blood. Cell salvage offers great blood savings opportunities but is thought to be contraindicated in a number of areas (e.g., blood contaminated with bacteria). Several outcome studies have suggested the safety of this technique in trauma and colorectal surgery, but many practitioners are still hesitant to apply cell salvage in the face of frank bacterial contamination. This study was undertaken to assess the efficacy of bacterial removal when cell salvage was combined with leukocyte depletion filtration. Expired packed erythrocytes were obtained and inoculated with a fixed amount of a stock bacteria (Escherichia coli American Type Culture Collections [ATCC] 25922, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 29213, or Bacteroides fragilis ATCC 25285) in amounts ranging from 2,000 to 4,000 colony forming units/ml. The blood was processed via a cell salvage machine. The washed blood was then filtered using a leukocyte reduction filter. The results for blood taken during each step of processing were compared using a repeated-measures design. Fifteen units of blood were contaminated with each of the stock bacteria. From the prewash sample to the postfiltration sample, 99.0%, 99.6%, 100%, and 97.6% of E. coli, S. aureus, P. aeruginosa, and B. fragilis were removed, respectively. Significant but not complete removal of contaminating bacteria was seen. An increased level of patient safety may be added to cell salvage by including a leukocyte depletion filter when salvaging blood that might be grossly contaminated with bacteria.

    We report our experience with the use of intra-arterial chemotherapy and embolization before limb salvage surgery in patients with osteosarcoma of the lower extremity. We evaluated the effect of this procedure on the degree of tumor necrosis and on the amount of blood loss during surgery. We reviewed the medical records of all patients who received intra-arterial chemotherapy and embolization before undergoing limb salvage surgery for osteosarcoma of the lower extremity at our institution between January 2003 and April 2008. Patient demographic, tumor characteristics, treatment details, postembolization complications, and surgical and pathological findings were recorded for each patient. We evaluated the operative time, estimated blood loss (EBL), and volume of blood transfusion during surgery and in the postoperative period in all patients in the study group. The same parameters were recorded for 65 other patients with lower extremity osteosarcoma who underwent limb salvage operation at our institution without undergoing preoperative intervention. The study included 47 patients (25 males and 22 females). Angiography showed that the tumors were hypervascular. Intra-arterial chemotherapy and embolization were performed successfully, resulting in a substantial reduction or complete disappearance of tumor stain in all patients. No major complications were encountered. At the time of surgery, performed 3-7 days after embolization, a fibrous edematous band around the tumor was observed in 43 of the 47 patients, facilitating surgery. The goal of limb salvage was achieved successfully in all cases. Percentage tumor necrosis induced by treatment ranged from 70.2% to 94.2% (average, 82.9%). EBL during surgery, EBL from drains in the postoperative period, total EBL, and transfusion volumes were significantly lower in the 47 study patients compared to the 65 patients who underwent surgery without preoperative treatment with intra-arterial chemotherapy and embolization.

    In order to predict postoperative pulmonary function after lung surgery, preoperative {sup 99m}Tc-macroaggregated albumin (MAA) lung perfusion scans with single-photon emission computed tomography (SPECT) were performed. Spirometry was also performed before and 4-6 months after surgery in 40 patients. In addition, changes in blood perfusion in the pre- and postoperative lung were examined by postoperative lung perfusion scans in 18 of the 40 patients. We measured the three-dimensional (3-D) imaging volume of the operative and contralateral lungs using the volumes rendering method at blood perfusion thresholds of 20, 50 and 75%, utilizing {sup 99m}Tc-MAA lung perfusion, and predicted pulmonary function by means of the measured volumes. We examined the correlation between predicted and the measured values of postoperative pulmonary function, forced vital capacity (FVC) and forced expiratory volume in one second (FEV{sub 1.0}). The correlation between FEV{sub 1.0} predicted by SPECT (threshold 50%) and measured postoperative lung function resembled that between lung function predicted by the standard planar method and measured FEV{sub 1.0} in the lobectomy group. We then examined the ratios of both pre- and postoperative blood perfusion volumes obtained using 3-D imaging at lung perfusion threshold ranges of 10% each (PV20-29, PV30-39) to pre- and postoperative total perfusion (PV20-100). In the lobectomy group, the postoperative PV20-29/PV20-100 value was significantly higher for the operative side lung than the preoperative PV20-29/PV20-100 value, and the postoperative PV50-59, 60-69, 70-79, 80-89 and 90-100/PV20-100 values were significantly lower than the respective preoperative values. However, in the contralateral lung, the respective pre- and postoperative PV/PV20-100 values were almost identical. These findings suggest that the rate of low blood perfusion increased while the rate of middle to high perfusion decreased in the lobectomy group in the operative

    Blood loss during total joint arthroplasty strongly influences the time to recover after surgery and the quality of the recovery. Blood conservation strategies such as pre-operative autologous blood donation and post-operative cell salvage are intended to avoid allogeneic blood transfusions and their associated risks. Although widely investigated, the real effectiveness of these alternative transfusion practices remains controversial. The surgery reports of 600 patients undergoing total joint arthroplasty (312 hip and 288 knee replacements) were retrospectively reviewed to assess transfusion needs and related blood management at our institute. Evaluation parameters included post-operative blood loss, haemoglobin concentration measured at different time points, ASA score, and blood transfusion strategies. Autologous blood donation increased the odds of receiving a red blood cell transfusion. Reinfusion by a cell salvage system of post-operative shed blood was found to limit adverse effects in cases of severe post-operative blood loss. The peri-operative net decrease in haemoglobin concentration was higher in patients who had predeposited autologous blood than in those who had not. The strengths of this study are the high number of cases and the standardised procedures, all operations having been performed by a single orthopaedic surgeon and a single anaesthesiologist. Our data suggest that a pre-operative autologous donation programme may often be useless, if not harmful. Conversely, the use of a cell salvage system may be effective in reducing the impact of blood transfusion on a patient's physiological status. Basal haemoglobin concentration emerged as a useful indicator of transfusion probability in total joint replacement procedures.

    When an implant becomes infected, implant salvage is often performed where the implant is removed, capsulectomy is performed, and a new implant is inserted. The patient is discharged with a PICC line and 6-8 weeks of intravenous (IV) antibiotics. This method has variable success and subjects the patient to long-term systemic antibiotics. In the 1960s, the use of antibiotic-impregnated beads for the treatment of chronic osteomyelitis was described. These beads deliver antibiotic directly to the site of the infection, thereby eliminating the complications of systemic IV antibiotics. This study aimed to present a case series illustrating the use of STIMULAN calcium sulfate beads loaded with vancomycin and tobramycin to increase the rate of salvage of the infected implant and forgo IV antibiotics. A retrospective analysis was performed of patients who were treated at Mount Sinai Hospital for implant infection with salvage and antibiotic beads. Twelve patients were identified, 10 of whom had breast cancer. Comorbidities included hypertension, smoking, and immunocompromised status. Infections were noted anywhere from 5 days to 8 years postoperatively. Salvage was successful in 9 out of the 12 infected implants using antibiotic bead therapy without home IV antibiotics. The use of antibiotic beads is promising for salvaging infected breast implants without IV antibiotics. Seventy-five percent of the implants were successfully salvaged. Of the three patients who had unsalvageable implants, one was infected with antibiotic-resistant Rhodococcus that was refractory to bead therapy and one was noncompliant with postoperative instructions.

    Pasquier, David; Ballereau, Charles

    2008-01-01

    Purpose: Given that postprostatectomy recurrence of prostate cancer occurs in 10-40% of patients, the best use of immediate postoperative radiotherapy (RT) in high-risk patients and salvage RT for biochemical recurrence remains a topic of debate. We assessed the levels of evidence (in terms of efficacy, prognostic factors, and toxicity) for the following treatment strategies: immediate postoperative RT alone, salvage RT alone, and the addition of androgen deprivation therapy to the two RT strategies. Methods and Materials: A systematic literature search for controlled randomized trials, noncontrolled trials, and retrospective studies between 1990 and 2008 was performed on PubMed, CancerLit, and MEDLINE. Only relevant articles that had appeared in peer-reviewed journals were selected. We report on the levels of evidence (according to the National Cancer Institute guidelines) supporting the various treatment strategies. Results: Immediate postoperative RT improves biochemical and clinical progression-free survival (Level of evidence, 1.ii) but has no significant effect on metastasis-free survival or overall survival. A pathologic review is of particular importance for correctly analyzing the treatment strategies. Low-grade morbidity has been significantly greater in the postoperative groups, but no severe toxicity has been observed. The influence of immediate postoperative RT on postprostatectomy continence appears to be slight; therefore, immediate postoperative RT should be considered in patients with major risk factors for local relapse (Level of evidence, 1.ii). On the basis of extensive retrospective data, salvage RT is effective in biochemical relapse after prostatectomy; some patients with few adverse prognostic factors might also benefit from salvage RT (Level of evidence, 3.ii). The addition of androgen deprivation therapy to immediate postoperative or salvage RT has only been supported by weak, retrospective data (Level of evidence, 3.ii). Conclusion

    Preoperative exposure to clopidogrel and aspirin significantly increases postoperative bleeding in patients undergoing on-pump coronary artery bypass graft surgery. Off-pump coronary bypass grafting has been proposed as an alternative technique to attenuate postoperative bleeding associated with clopidogrel. This study aimed to determine the effects of aspirin and clopidogrel therapy on perioperative blood loss and blood transfusion requirements in off-pump coronary artery bypass grafting. One hundred six patients scheduled for off-pump coronary artery bypass grafting were divided into three groups: aspirin and clopidogrel discontinued more than 6 days before surgery (group 1, n = 35), aspirin and clopidogrel continued until 3 to 5 days before surgery (group 2, n = 51), and both medications continued within 2 days of surgery (group 3, n = 20). Thromboelastographic tracings were analyzed before induction of anesthesia. Routine coagulation profiles were measured before and after surgery. A cell salvage device was used during surgery and salvaged blood was reinfused. Chest tube drainage and blood transfusion requirement were recorded postoperatively. Patient characteristics, operative data, and thromboelastographic tracings were similar among the groups. There were significant decreases in hematocrit level and platelet count and prolongation in prothrombin time postoperatively in all groups without any intergroup differences. The amounts of perioperative blood loss and blood transfusion required were all similar among the groups. Preoperative clopidogrel and aspirin exposure even within 2 days of surgery does not increase perioperative blood loss and blood transfusion requirements in patients undergoing elective off-pump coronary artery bypass grafting.

    Transfusion of blood products and mechanical ventilation with injurious settings are considered risk factors for postoperative lung injury in surgical Patients. A systematic review and individual patient data meta-analysis was done to determine the independent effects of peri-operative transfusion of blood products, intra-operative tidal volume and airway pressure in adult patients undergoing mechanical ventilation for general surgery, as well as their interactions on the occurrence of postoperative acute respiratory distress syndrome (ARDS). Observational studies and randomized trials were identified by a systematic search of MEDLINE, CINAHL, Web of Science, and CENTRAL and screened for inclusion into a meta-analysis. Individual patient data were obtained from the corresponding authors. Patients were stratified according to whether they received transfusion in the peri-operative period [red blood cell concentrates (RBC) and/or fresh frozen plasma (FFP)], tidal volume size [≤7 mL/kg predicted body weight (PBW), 7-10 and >10 mL/kg PBW] and airway pressure level used during surgery (≤15, 15-20 and >20 cmH 2 O). The primary outcome was development of postoperative ARDS. Seventeen investigations were included (3,659 patients). Postoperative ARDS occurred in 40 (7.2%) patients who received at least one blood product compared to 40 patients (2.5%) who did not [adjusted hazard ratio (HR), 2.32; 95% confidence interval (CI), 1.25-4.33; P=0.008]. Incidence of postoperative ARDS was highest in patients ventilated with tidal volumes of >10 mL/kg PBW and having airway pressures of >20 cmH 2 O receiving both RBC and FFP, and lowest in patients ventilated with tidal volume of ≤7 mL/kg PBW and having airway pressures of ≤15 cmH 2 O with no transfusion. There was a significant interaction between transfusion and airway pressure level (P=0.002) on the risk of postoperative ARDS. Peri-operative transfusion of blood products is associated with an increased risk of

    Acute kidney injury (AKI), which is a major complication after cardiovascular surgery, is associated with significant morbidity and mortality. Diuretic agents are frequently used to improve urine output and to facilitate fluid management in these patients. Mannitol, an osmotic diuretic, is used in the perioperative setting in the belief that it exerts reno-protective properties. In a recent study on uncomplicated postcardiac-surgery patients with normal renal function, mannitol increased glomerular filtration rate (GFR), possibly by a deswelling effect on tubular cells. Furthermore, experimental studies have previously shown that renal ischemia causes an endothelial cell injury and dysfunction followed by endothelial cell edema. We studied the effects of mannitol on renal blood flow (RBF), glomerular filtration rate (GFR), renal oxygen consumption (RVO2), and extraction (RO2Ex) in early, ischemic AKI after cardiac surgery. Eleven patients with AKI were studied during propofol sedation and mechanical ventilation 2 to 6 days after complicated cardiac surgery. All patients had severe heart failure treated with one (100%) or two (73%) inotropic agents and intraaortic balloon pump (36%). Systemic hemodynamics were measured with a pulmonary artery catheter. RBF and renal filtration fraction (FF) were measured by the renal vein thermo-dilution technique and by renal extraction of chromium-51-ethylenediaminetetraacetic acid (51Cr-EDTA), respectively. GFR was calculated as the product of FF and renal plasma flow RBF × (1-hematocrit). RVO2 and RO2Ex were calculated from arterial and renal vein blood samples according to standard formulae. After control measurements, a bolus dose of mannitol, 225 mg/kg, was given, followed by an infusion at a rate of 75 mg/kg/h for two 30-minute periods. Mannitol did not affect cardiac index or cardiac filling pressures. Mannitol increased urine flow by 61% (P renal vascular resistance (P renal FF. Mannitol treatment of postoperative AKI

    The effects of re-infusion drains on the rate of allogeneic blood transfusion and post-op haemoglobin levels in Total Knee Arthroplasty were examined. A group of 22 patients undergoing primary Total Knee Arthroplasty using a CBCII Constavac Stryker re-infusion drainage system were compared with a group of 30 patients, matched for age, sex and type of prosthesis but without any drain usage. The re-infusion drain.group had a significantly lower day 1 and day 3 post-operative haemoglobin compared to the non-drainage group. The re-infusion drain group had a higher allogenic transfusion rate compared to the non-drainage group. There were no significant differences between the two groups regarding the rate of wound and transfusion related complications and mean length of post-operative stay. We found that reinfusion drains were ineffective in reducing allogeneic transfusion requirements as compared with non-drainage in total knee arthroplasty.

    Previous trials have indicated that cell salvage may reduce allogeneic blood transfusion during cardiac surgery, but these studies have limitations, including inconsistent use of other blood transfusion-sparing strategies. We designed a randomized controlled trial to determine whether routine cell salvage for elective uncomplicated cardiac surgery reduces blood transfusion and is cost effective in the setting of a rigorous transfusion protocol and routine administration of antifibrinolytics. Two-hundred-thirteen patients presenting for first-time coronary artery bypass grafting and/or cardiac valve surgery were prospectively randomized to control or cell salvage groups. The latter group had blood aspirate during surgery and mediastinal drainage the first 6 h after surgery processed in a cell saver device and autotransfused. All patients received tranexamic acid and were subjected to an algorithm for red blood cell and hemostatic blood factor transfusion. There was no difference between the two groups in the proportion of patients exposed to allogeneic blood (32% in both groups, relative risk 1.0 P = 0.89). At current blood products and cell saver prices, the use of cell salvage increased the costs per patient by a minimum of $103. When patients who had mediastinal re-exploration for bleeding were excluded (as planned in the protocol), significantly fewer units of allogeneic red blood cells were transfused in the cell salvage compared with the control group (65 vs 100 U, relative risk 0.71 P = 0.04). In patients undergoing routine first-time cardiac surgery in an institution with a rigorous blood conservation program, the routine use of cell salvage does not further reduce the proportion of patients exposed to allogeneic blood transfusion. However, patients who do not have excessive bleeding after surgery receive significantly fewer units of blood with cell salvage. Although the use of cell savage may reduce the demand for blood products during cardiac surgery, this

    Perioperative blood pressure management by targeting individualized optimal blood pressure, determined by cerebral blood flow autoregulation monitoring, may ensure sufficient renal perfusion. The purpose of this study was to evaluate changes in the optimal blood pressure for individual patients, determined during cardiopulmonary bypass (CPB) and during early postoperative period in intensive care unit (ICU). A secondary aim was to examine if excursions below optimal blood pressure in the ICU are associated with risk of cardiac surgery-associated acute kidney injury (CSA-AKI). One hundred and ten patients undergoing cardiac surgery had cerebral blood flow monitored with a novel technology using ultrasound tagged near infrared spectroscopy (UT-NIRS) during CPB and in the first 3 h after surgery in the ICU. The correlation flow index (CFx) was calculated as a moving, linear correlation coefficient between cerebral flow index measured using UT-NIRS and mean arterial pressure (MAP). Optimal blood pressure was defined as the MAP with the lowest CFx. Changes in optimal blood pressure in the perioperative period were observed and the association of blood pressure excursions (magnitude and duration) below the optimal blood pressure [area under the curve (AUC) blood pressure during early ICU stay and CPB was correlated (r = 0.46, P AUC blood pressure during CPB and in the ICU was correlated. Excursions below optimal blood pressure (AUC blood pressure management based on cerebral autoregulation monitoring during the perioperative period may help improve CSA-AKI-related outcomes. © The Author 2016.

    The pulmonary blood distribution was examined in 17 patients with tetralogy of Fallot (TOF) pre and postoperatively with macroaggregates of [sup 99m]TC-labeled human serum albumin. Most of the patients with TOF demonstrated an abnormal preoperative distribution pattern. The abnormalities included not only an unbalanced distribution between the right and left lungs but also a maldistribution of peripheral vessels in each lung. The right/left lung counts ratio and pulmonary peripheral index (calculated in order to express the severity of peripheral maldistribution) correlated neither to the diameter nor the cross-sectional area of either right or left pulmonary arteries which were measured angiographically. Postoperatively, the pulmonary blood was shunted toward the developed side of the lung which further contributed to maldistribution of blood flow and unbalanced pulmonary growth. Since the patients with an unbalanced pulmonary blood distribution demonstrated a higher right ventricular pressure one year after the operation, a palliative operation facilitating the growth of the underdeveloped side of the lung might be considered as an effective procedure to precede intracardiac repair.

    Odontogenic chronic rhinosinusitis (CRS) is an epidemiologically important disease process due, in part, to the increasingly commonplace use of dental restorative procedures such as zygomatic implantation. Traditional management of this clinical entity typically entails extraction of the infected hardware via an open or endoscopic approach. We describe a novel management strategy of odontogenic CRS following bilateral zygomatic implantation for oral rehabilitation that we surgically salvaged via a modified endoscopic medial maxillectomy. We describe the presentation and management of a case of metachronous development of bilateral CRS subsequent to zygomatic implantation. The patient's postoperative course was characterized by marked endoscopic, radiologic, and symptomatic improvement as measured by the 22-item Sino-Nasal Outcome Test. We describe a novel treatment strategy for the management of odontogenic sinusitis resulting from erroneous zygomatic implant placement. Modified endoscopic medial maxillectomy in this clinical context facilitates mucosal normalization of the affected sinus, while permitting preservation of oral function through salvage of the displaced implant.

    The value of temporary intraoperative porto-caval shunts (TPCS) in cava-sparing liver transplantation is discussed controversially. Aim of this meta-analysis was to analyze the impact of temporary intraoperative porto-caval shunts on liver injury, primary non-function, time of surgery, transfusion of blood products and length of hospital stay in cava-sparing liver transplantation. A systematic search of MEDLINE/PubMed, EMBASE and PsycINFO retrieved a total of 909 articles, of which six articles were included. The combined effect size and 95 % confidence interval were calculated for each outcome by applying the inverse variance weighting method. Tests for heterogeneity (I 2 ) were also utilized. Usage of a TPCS was associated with significantly decreased AST values, significantly fewer transfusions of packed red blood cells and improved postoperative renal function. There were no statistically significant differences in primary graft non-function, length of hospital stay or duration of surgery. This meta-analysis found that temporary intraoperative porto-caval shunts in cava-sparing liver transplantation reduce blood loss as well as hepatic injury and enhance postoperative renal function without prolonging operative time. Randomized controlled trials investigating the use of temporary intraoperative porto-caval shunts are needed to confirm these findings.

    Perioperative autologous blood salvage and preoperative erythropoietin are not (cost) effective to reduce allogeneic transfusion in primary hip and knee arthroplasty, but are still used. This study aimed to evaluate the effectiveness of a theoretically informed multifaceted strategy to de-implement these low-value blood management techniques. Twenty-one Dutch hospitals participated in this pragmatic cluster-randomized trial. At baseline, data were gathered for 924 patients from 10 intervention and 1040 patients from 11 control hospitals undergoing hip or knee arthroplasty. The intervention included a multifaceted de-implementation strategy which consisted of interactive education, feedback on blood management performance, and a comparison with benchmark hospitals, aimed at orthopedic surgeons and anesthesiologists. After the intervention, data were gathered for 997 patients from the intervention and 1096 patients from the control hospitals. The randomization outcome was revealed after the baseline measurement. Primary outcomes were use of blood salvage and erythropoietin. Secondary outcomes included postoperative hemoglobin, length of stay, allogeneic transfusions, and use of local infiltration analgesia (LIA) and tranexamic acid (TXA). The use of blood salvage (OR 0.08, 95% CI 0.02 to 0.30) and erythropoietin (OR 0.30, 95% CI 0.09 to 0.97) reduced significantly over time, but did not differ between intervention and control hospitals (blood salvage OR 1.74 95% CI 0.27 to 11.39, erythropoietin OR 1.33, 95% CI 0.26 to 6.84). Postoperative hemoglobin levels were significantly higher (β 0.21, 95% CI 0.08 to 0.34) and length of stay shorter (β -0.36, 95% CI -0.64 to -0.09) in hospitals receiving the multifaceted strategy, compared with control hospitals and after adjustment for baseline. Transfusions did not differ between the intervention and control hospitals (OR 1.06, 95% CI 0.63 to 1.78). Both LIA (OR 0.0, 95% CI 0.0 to 0.0) and TXA (OR 0.3, 95% CI 0.2 to 0

    Full Text Available Background and objectives: Hydroxyethyl starch (HES 130/0.4 is considered an effective plasma expander when compared to crystalloids. There is controversy around its superiority regarding hemodynamic optimization and about possible detrimental effects on coagulation. The aim of this study was to compare the effects of HES 130/0.4 to lactated Ringer solution during hip arthroplasty in adult patients under spinal anesthesia regarding intraoperative bleeding, hemodynamic parameters, coagulation profile, transfusion requirements and clinical outcomes. Methods: In this randomized, controlled trial, 48 patients scheduled for hip arthroplasty with spinal anesthesia were randomized into two groups: 24 patients were allocated to receive a preload of 15 mL.kg-1 of HES 130/0.4 and 24 patients received a preload of 30 mL.kg-1 lactated Ringer solution before surgery. Hemodynamic measurements, hemoglobin concentrations, biochemical parameters and coagulation tests were evaluated in three periods during surgical procedure. Patients received medical follow-up during their hospital stay and up to postoperative 30 days. Primary outcome was the requirement of red blood cell transfusion between groups during hospital stay. Secondary outcome were hemodynamic parameters, length of hospital stay, mortality and occurrence of clinical postoperative complications. Results: Red blood cell transfusion was required in 17% of patients in the HES group and in 46% in the Ringer group (p = .029. Postoperative infections were more frequently observed in the Ringer group (17% compared to the HES group (0, p = .037. There were no significant differences between groups in mortality, hospital length of stay and clinical complications other than infection. Conclusions: During hip arthroplasty, patients treated with hypervolemic hemodilution with hydroxyethyl starch 130/0.4 required less transfusion and presented lower infection rate compared to patients who received lactated

    Perioperative blood loss is a major problem in elective orthopedic surgery. Allogeneic transfusion is the standard treatment for perioperative blood loss resulting in low postoperative hemoglobin, but it has a number of well-recognized risks, complications, and costs. Alternatives to allogeneic blood transfusion include preoperative autologous donation and intraoperative salvage with postoperative autotransfusion. Orthopedic surgeons are often unaware of the different pre- and intraoperative possibilities of reducing blood loss and leave the management of coagulation and use of blood products completely to the anesthesiologists. The goal of this review is to compare alternatives to allogeneic blood transfusion from an orthopedic and anesthesia point of view focusing on estimated costs and acceptance by both parties.

    Salvage lymph node dissection has been described as a feasible treatment for the management of prostate cancer patients with nodal recurrence after primary treatment. To report perioperative, pathologic, and oncologic outcomes of robot-assisted salvage nodal dissection (RASND) in patients with nodal recurrence after radical prostatectomy (RP). We retrospectively evaluated 16 patients affected by nodal recurrence following RP documented by positive positron emission tomography/computed tomography scan. Surgery was performed using DaVinci Si and Xi systems. A pelvic nodal dissection that included lymphatic stations overlying the external, internal, and common iliac vessels, the obturator fossa, and the presacral nodes was performed. In 13 (81.3%) patients a retroperitoneal lymph node dissection that included all nodal tissue located between the aortic bifurcation and the renal vessels was performed. Perioperative outcomes consisted of operative time, blood loss, length of hospital stay, and complications occurred within 30 d after surgery. Biochemical response (BR) was defined as a prostate-specific antigen level <0.2 ng/ml at 40 d after RASND. Median operative time, blood loss, and length of hospital stay were 210min, 250ml, and 3.5 d. The median number of nodes removed was 16.5. Positive lymph nodes were detected in 11 (68.8%) patients. Overall, four (25.0%) and five (31.2%) patients experienced intraoperative and postoperative complications, respectively. Overall, one (6.3%) and four (25.0%) patients had Clavien I and II complications within 30 d after RASND, respectively. Overall, five (33.3%) patients experienced BR after surgery. Our study is limited by the small cohort of patients evaluated and by the follow-up duration. RASND represents a feasible procedure in patients with nodal recurrence after RP and provides acceptable short-term oncologic outcomes, where one out of three patients experience BR immediately after surgery. Long-term data are needed to

    The objective of this study was to examine the post-operative complications of surgical procedures in oral or pharyngeal carcinoma by analyzing and comparing between patients who underwent salvage surgery after chemoradiation and radiation. A retrospective review was performed of 18 patients who underwent salvage surgery and reconstruction after concurrent chemoradiotherapy (CCRT group), and another 41 patients who underwent salvage surgery and reconstruction after radiation therapy (RT group). No perioperative deaths or life threatening systemic complications occurred, and all flaps survived completely in both groups. Surgical site infection (SSI) occurred in five patients (12.2%) in the RT group and seven patients (38%) in the CCRT group. SSI other than donor site infection occurred in four patients (9%) in the RT group and four patients (22%) in the CCRT group. The rate of SSI excluding donor site infection did not differ significantly between patients who underwent salvage surgery after CCRT and RT. The rate of donor site infection was higher in the CCRT group than in the RT group (p=0.04). This study showed that salvage surgery after CCRT or RT can be performed safely, without significant morbidity or mortality. However, patients who received CCRT are at risk for major complications caused by minor troubles, and thus reconstruction after salvage surgery should be performed with sufficient care. (author)

    The results of salvage surgery or cryosurgery performed in 62 cases or oral or oropharyngeal cancer, recurring or persisting after radical radiotherapy, were analysed retrospectively. Salvage surgery was performed in 33 cases. The relatively high frequency of postoperative complications observed in years 1973-1984 has declined since 1985, concomitant with the introduction of myocutaneous flaps for reconstruction. Twenty-nine patients who were disqualified from major surgery, were treated by cryosurgery. Using both methods, 3-year overall survival was obtained in 24.1% of cases. (author)

    To investigate the postoperative analgesic effects of preemptive dexketoprofen trometamol in dogs subjected to ovariohysterectomy (OHE). Seventeen adult bitches of various breeds were used in this study. The dogs were randomly allocated into of two groups. Subjects in the dexketoprofen trometamol (DEX) group (n=10), received intravenous (i.v.) dexketoprofen trometamol, 1 mg/kg, 15 minutes before premedication, while those assigned to the control (C) group (n=7) were given no analgesics prior to premedication. Pain level was assessed by two researchers before the administration of anaesthesia (15 minutes before start) and 0, 1, 2, 4 and 6 hours after surgery. A modified University of Melbourne Pain Scale (UMPS) was used to evaluate pain in both groups. Serum cortisol level changed from 0 to 1 h and from 0 to 1 to 4 h were compared between the groups; the increase in the C group was statistically significant. The modified UMPS was applied to both groups at baseline and postoperative 1, 2, 4 and 6 h. According to this test, the values for DEX were significantly lower than controls at 4 and 6 h (pdexketoprofen administration are a promising finding. The clinical advantage shown by the pain scale difference and the low serum cortisol levels should qualify dexketoprofen for preemptive pain management in dogs (Tab. 5, Fig. 2, Ref. 30).

    To investigate whether a liberal blood transfusion strategy [Hb levels ≥11.3 g/dL (7 mmol/L)] reduces the risk of postoperative delirium (POD) on day 10, among nursing home residents with hip fracture, compared to a restrictive transfusion strategy [Hb levels ≥9.7 g/dL (6 mmol/L)]. Furthermore, to investigate whether POD influences mortality within 90 days after hip surgery. This is a post hoc analysis based on The TRIFE - a randomized controlled trial. Frail anemic patients from the Orthopedic Surgical Ward at Aarhus University Hospital were enrolled consecutively between January 18, 2010 and June 6, 2013. These patients (aged ≥65 years) had been admitted from nursing homes for unilateral hip fracture surgery. After surgery, 179 patients were included in this study. On the first day of hospitalization, all enrolled patients were examined for cognitive impairment (assessed by MMSE) and delirium (assessed by CAM). Delirium was also assessed on the tenth postoperative day. The prevalence of delirium was 10 % in patients allocated to a liberal blood transfusion strategy (LB) and 21 % in the group with a restrictive blood transfusion strategy (RB). LB prevents development of delirium on day 10, compared to RB, odds ratio 0.41 (95 % CI 0.17-0.96), p = 0.04. Development of POD on day 10 increased the risk of 90-day death, hazard ratio 3.14 (95 % CI 1.72-5.78), p < 0.001. In nursing home residents undergoing surgery for hip fracture, maintaining hemoglobin level above 11.3 g/dL reduces the rate of POD on day 10 compared to a RB. Development of POD is associated with increased mortality.

    The goal of treating primary bone and soft tissue tumors, as with most other malignancies, is to control the disease locally and systematically while preserving as much function as possible. For soft tissue sarcomas the results following radical excision and post-operative radiation therapy with preservation of the limb have equaled the control rates of amputation. However, local recurrence rates of approximately 25-30% are reported for high-grade lesions of the proximal lower extremity. Amputations provides excellent local control for osteosarcoma but the functional results may be less than optimal. In an attempt to achieve limb salvage for these tumors, a multidisciplinary protocol was developed using intra-arterial doxorubicin, pre-operative radiation therapy and limb-sparing radical wide excision followed by post-operative chemotherapy for presumed micro-metastatic disease

  19. Role of salvage esophagectomy after definitive chemoradiotherapy

    2009-01-01

    Chemoradiotherapy has become a popular definitive therapy among many patients and oncologists for potentially resectable esophageal carcinoma. Although the complete response rates are high and short-term survival is favorable after chemoradiotherapy, persistent or recurrent locoregional disease is quite frequent. Salvage surgery is the sole curative intent treatment option for this course. As experience with definitive chemoradiotherapy grows, the number of salvage surgeries may increase. Selected articles about salvage esophagectomy after definitive chemoradiotherapy for esophageal carcinoma are reviewed. The number of salvage surgeries was significantly lower than the number of expected candidates. To identify candidates for salvage surgery, patients undergoing definitive chemoradiotherapy should be followed up carefully. Salvage esophagectomy is difficult when dissecting fibrotic masses from irradiated tissues. Patients who underwent salvage esophagectomy had increased morbidity and mortality. Pulmonary complications such as pneumonia and acute respiratory distress syndrome were common. The anastomotic leak rate was significantly increased because of the effects of the radiation administered to the tissues used as conduits. The most significant factor associated with long-term survival appeared to be complete resection. However, precise evaluation of resectability before operation was difficult. Nevertheless, increased morbidity and mortality will be acceptable in exchange for potential long-term survival after salvage esophagectomy. Such treatment should be considered for carefully selected patients at specialized centers. (author)

    Full Text Available OBJECTIVE: To summarize the experience with salvage liver transplantation (SLT for patients with recurrent hepatocellular carcinoma (HCC after primary hepatic resection in a single center. METHODS: A total of 376 adult patients with HCC underwent orthotopic liver transplantation (OLT at Organ Transplantation Center, the First Affiliated Hospital of Sun Yat-sen University, between 2004 and 2008. Among these patients, 36 underwent SLT after primary liver curative resection due to intrahepatic recurrence. During the same period, one hundred and forty-seven patients with HCC within Milan criteria underwent primary OLT (PLTW group, the intra-operative and post-operative parameters were compared between these two groups. Furthermore, we compared tumor recurrence and patient survival of patients with SLT to 156 patients with HCC beyond Milan criteria (PLTB group. Cox Hazard regression was made to identify the risk factors for tumor recurrence. RESULTS: The median interval between initial liver resection and SLT was 35 months (1-63 months. The intraoperative blood loss (P0.05. When compared to those patients with HCC beyond Milan criteria undergoing primary OLT, patients undergoing SLT achieved a better survival and a lower tumor recurrence. Cox Proportional Hazards model showed that vascular invasion, including macrovascular and microvascular invasion, as well as AFP level >400 IU/L were risk factors for tumor recurrence after LT. CONCLUSIONS: In comparison with primary OLT, although SLT is associated with increased operation difficulties, it provides a good option for patients with HCC recurrence after curative resection.

    Although free flap is gaining popularity for the reconstruction of diabetic foot ulcers, it is unclear whether free flap reconstruction increases the chances of postoperative independent ambulation. The aim of this study is to evaluate the relationship between free flap success and postoperative ambulation. This study reviewed 23 cases of free flap reconstruction for diabetic foot ulcers between January 2007 and March 2014. Free rectus abdominis, latissimus dorsi, and anterolateral thigh flaps were used in ten, eight, and five patients, respectively. A comparison was made between free flap success and postoperative independent ambulation using Fisher's exact test. Two patients developed congestive heart failure with fatal consequences within 14 days postoperatively, resulting in an in-hospital mortality rate of 8.7%. Five patients lost their flaps (21.7%). Of the 16 patients who had flap success, 12 achieved independent ambulation. Five patients with flap loss did not achieve independent ambulation, except one patient who underwent secondary flap reconstruction using a distally based sural flap. Fisher's exact test revealed that independent ambulation was associated with free flap success (p = 0.047). The present study indicates that free flap reconstruction may increase the possibility of independent ambulation for patients with extensive tissue defects due to diabetic ulcers. Intermediate limb salvage rates and independent ambulation rates were favourable in patients with successful reconstruction. The use of foot orthoses and a team approach with pedorthists were effective to prevent recurrence.

Case series survey. Tertiary care, major university teaching hospital. Four patients with religious objections to blood transfusions who were selected on the basis of restrictive criteria that would lower their risk for fatal hemorrhage, including coagulopathy, a thrombosed splanchnic venous system requiring extensive reconstruction, active bleeding and associated medical complications. All patients were pretreated with erythropoietin to increase production of red blood cells. All operations were performed at the same institution, with a 36-month follow-up. Orthotopic liver transplantation that used blood salvage, plateletpheresis, and autotransfusion and the withholding of the use of human blood products with the exception of albumin. Survival and postoperative complications, with the effectiveness of erythropoietin and plateletpheresis as secondary measures. All patients are alive at 36 months after orthotopic liver transplantation. One patient, a minor (13 years of age), was transfused per a state court ruling. Erythropoietin increased the production of red blood cells as shown by a mean increase in hematocrit levels of 0.08. Platelet-pheresis allowed autologous, platelet-rich plasma to be available for use after allograft reperfusion. Three major complications were resolved or corrected without sequelae. Only one patient developed postoperative hemorrhage, which was corrected surgically. The mean charge for bloodless surgery was $174,000 for the three patients with United Network for Organ Sharing (UNOS) status 3 priority for transplantation. This result was statistically significant when these patients were compared with all the patients with UNOS status 3 priority during the same period who met the same restrictive guidelines (P blood products is possible

    Clinical outcome of limb salvage procedure combined with intraoperative irradiation was investigated in 6 patients with osteosarcoma in the distal part of femur (n=4) and proximal part of tibia (n=2). They ranged in age from 12 to 54 years, with a mean of 22.5. First, a lesion was separated from the surrounding soft tissue with curatively wide margin. Osteotomy was performed at the portion of diaphysis. After irradiation field was setted up by lifting the lesion, and was exposed to doses ranging from 60 Gy to 85 Gy of intraoperative irradiation, soft tissue and fragile tumor tissue, excluding joint capsule and ligament, were removed as soon as possible. Finally, bone was jointed by means of inner fixation or bone grafting. They had a median follow-up of one year and four months after surgery. Although superficial wound infection and delayed wound adhesion were encountered as postoperative complications in one and two patients, respectively, these were all healed. None of the patients had local recurrence. The ability of salvaged limb was excellent in one, good in 3, and fair in 2 patients. Because both of the two patients with sarcoma in the proximal part of tibia had excellent and good limb ability, this procedure was considered useful especially for sarcoma in the proximal part of tibia.

    The benefits of extreme lateral interbody fusion (XLIF) as a minimally invasive lumbar spinal fusion treatment for lumbar degenerative spondylolisthesis have been unclear. We sought to evaluate the invasiveness and tolerability of XLIF with percutaneous pedicle screws (PPS) compared with traditional open posterior lumbar interbody fusion (PLIF). Fifty-six consecutive patients underwent open PLIF and 46 consecutive patients underwent single-staged treatment with XLIF with posterior PPS fixation for degenerative lumbar spondylolisthesis, and were followed up for a minimum of 1 year. We analyzed postoperative serum makers for muscle damage and inflammation, postoperative surgical pain, and performance status. A Roland-Morris Disability Questionnaire (RDQ) and Oswestry Disability Index (ODI) were obtained at the time of hospital admission and 1 year after surgery. Intraoperative blood loss (51 ± 41 ml in the XLIF/PPS group and 206 ± 191 ml in the PLIF group), postoperative WBC counts and serum CRP levels in the XLIF/PPS group were significantly lower than in the PLIF group. Postoperative serum CK levels were significantly lower in the XLIF/PPS group on postoperative days 4 and 7. Postoperative recovery of performance was significantly greater in the XLIF/PPS group than in the PLIF group from postoperative days 2 to 7. ODI and visual analog scale (VAS) score (lumbar) 1 year after surgery were significantly lower in the XLIF/PPS group compared with the PLIF group. The XLIF/PPS procedure is advantageous to minimize blood loss and muscle damage, with consequent earlier recovery of daily activities and reduced incidence of low back pain after surgery than with the open PLIF procedure.

    Full Text Available Background: Patients undergoing surgery for prostate cancer who have adverse pathological findings experience high rates of recurrence. While there are data supporting adjuvant radiotherapy compared to a wait-and-watch strategy to reduce recurrence rates, there are no randomized controlled trials comparing adjuvant radiotherapy with the other standard of care, salvage radiotherapy (radiotherapy administered at the time of recurrence. Methods: We constructed a health state transition (Markov model employing two-dimensional Monte Carlo simulation using a lifetime horizon to compare the quality-adjusted survival associated with postoperative strategies using adjuvant or salvage radiotherapy. Prior to analysis, we calibrated and validated our model using the results of previous randomized controlled trials. We considered clinically important oncological health states from immediately postoperative to prostate cancer–specific death, commonly described complications from prostate cancer treatment, and other causes of mortality. Transition probabilities and utilities for disease states were derived from a literature search of MEDLINE and expert consensus. Results: Salvage radiotherapy was associated with an increased quality-adjusted life expectancy (QALE (58.3 months as compared with adjuvant radiotherapy (53.7 months, a difference of 4.6 months (standard deviation 8.8. Salvage radiotherapy had higher QALE in 53% of hypothetical cohorts. There was a minimal difference in overall life expectancy (-0.1 months. Examining recurrence rates, our model showed validity when compared with available randomized controlled data. Conclusions: A salvage radiotherapy strategy appears to provide improved QALE for patients with adverse pathological findings following radical prostatectomy, compared with adjuvant radiotherapy. As these findings reflect, population averages, specific patient and tumor factors, and patient preferences remain central for individualized

    Hematomas may develop in the postoperative setting after free tissue transfer. When hematomas occur, they can exert pressure on surrounding tissues. Their effect on the vascular pedicle of a free flap is unknown. We describe our incidence of hematoma in free flaps and outcomes when the flap is compromised. Retrospective chart review of 1,883 free flaps performed between July 1998 and June 2014 at a tertiary referral center. Patients with free flap compromise due to hematoma were identified. Etiology, demographic data, and outcomes were evaluated. Eighty-eight (4.7%) patients developed hematomas. Twenty (22.7%) of those had flap compromise. Twelve compromises (60%) showed evidence of pedicle thrombosis. The salvage rate was 75% versus 54% in 79 flaps with compromise from other causes (P = .12). Mean time to detection of the hematoma was 35.3 hours in salvaged flaps compared to 91.6 hours in unsalvageable flaps (P = .057). Time to operating room (OR) from detection was 2.8 hours in salvageable flaps compared to 12.4 hours in nonsalvageable flaps (P = .053). The salvage rate for flaps that returned to the OR in hematomas developed rarely. When they did, 23% went on to develop flap compromise. Prompt recognition and re-exploration allowed for a high salvage rate. Vessel thrombosis predicted inability to salvage the flap. 4 © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    There is increasing concern about the safety of homologous blood transfusion during cardiac surgery, and a restrictive transfusion practice is associated with improved outcome. Transfusion-free pediatric cardiac surgery is unrealistic for the vast majority of procedures in neonates or small infants; however, considerable progress has been made by using techniques that decrease the need for homologous blood products or even allow bloodless surgery in older infants and children. These techniques involve a decrease in prime volume by downsizing the bypass circuit with the help of vacuum-assisted venous drainage, microplegia, autologous blood predonation with or without infusion of recombinant (erythropoietin), cell salvaging, ultrafiltration and retrograde autologous priming. The three major techniques which are simple, safe, efficient, and cost-effective are: a prime volume as small as possible, cardioplegia with negligible hydric balance and circuit residual blood salvaged without any alteration. Furthermore, these three techniques can be used for all the patients, including emergencies and small babies. In every pediatric surgical unit, a strategy to decrease or avoid blood bank transfusion must be implemented. A strategy to minimize transfusion requirement requires a combined effort involving the entire surgical team with pre-, peri-, and postoperative planning and management.

    Purpose: To assess the ability of adjuvant irradiation to prevent PSA failure in cases of pT3N0 disease, and of salvage irradiation to durably suppress a rising PSA following radical prostatectomy. Methods and Materials: 62 patients treated by post-operative radiation therapy (60-64Gy in 1.8Gy fractions to the tumor bed) between 1988 and 1993 were evaluated. All had complete pre- and post-radiation PSA data. Median follow up was 3.2 years from time of surgery and 2.2 years from irradiation. 20 patients had Gleason grade 3 disease (moderately differentiated) and 41 Gleason 4-5 (poorly differentiated). 46 had positive inked surgical margins, 18 involved seminal vesicles and 5 had palpable recurrent disease. None had known nodal or metastatic disease. 32 patients underwent adjuvant treatment (undetectable PSA at time of irradiation) and 30 salvage (detectable PSA at time of irradiation). Kaplan-Meier life table analysis was employed. The endpoint studied was freedom from biochemical failure. This was defined as a rise in the PSA of greater than 10% (intra laboratory error <8%) or a previously undetectable PSA becoming detectable. Results: The overall actuarial freedom from biochemical failure at 4 years from radiotherapy was 59%. A significant difference was seen between those receiving adjuvant and those receiving salvage irradiation (71% vs 51%, p=0.03). Amongst those in the salvage group neither the PSA prior to surgery, the PSA at the time of irradiation, the seminal vesicle status, nor the Gleason score (3 vs 4-5) correlated significantly with outcome. The time interval between surgery and irradiation was, however, significant. Those being treated within 6 months fared better than those treated later (60% vs 36%, p=0.04). Further, those treated early were more likely to achieve an undetectable nadir PSA level (94% vs 71%). Conclusion: The addition of adjuvant irradiation appears to improve the 4 year biochemical disease-free survival of patients with poor

    Full Text Available Summary:. Autologous breast reconstruction has become a standard option during the recovery of breast cancer survivors. Although pedicle damage is a rare complication of this procedure, extensive torsion or tension can lead to partial or total flap failure. We report a case of partial flap salvage after accidental transection of the pedicled blood supply within the intramuscular course of a latissimus dorsi musculocutaneous flap. This salvage technique involved microvascular anastomosis between the remaining vasculature of the latissimus dorsi pedicle and the serratus branch of the thoracodorsal artery and vein.

    There are limited treatment options beyond surgical salvage for patients who fail nonoperative treatment for laryngeal squamous cell carcinoma. In this study, we examine the failure patterns after surgical salvage and the potential pathologic and clinical prognostic variables that might guide further postoperative intensification investigation. Retrospective analysis at a tertiary academic referral center. From an institutional review board-approved institutional head and neck cancer registry, a consecutive series of 147 patients who underwent salvage laryngectomy for squamous cell cancer recurrence or persistence after radiotherapy with or without chemotherapy between May 1995 and May 2016 were identified. Variables potentially associated with oncologic outcome after surgical salvage were then collected and retrospectively evaluated. The projected 2-year locoregional failure rate was 21.8% (95% confidence interval [CI], 14.6%-29.0%]), and the overall survival 65% (95% CI, 57.5%-74.3%) for the entire cohort after salvage laryngectomy. On multivariable analysis, sarcomatoid/spindle cell pathology (hazard ratio [HR], 3.147; 95% CI, 1.181-8.386; P = 0.022), lymphovascular space invasion (LVSI) (positive vs. negative; HR, 2.31; 95% CI, 1.21-4.42; P = 0.011), and advanced initial American Joint Committee on Cancer 7th Edition grouped stage (stages III-IVB vs. stages I-II; HR, 1.64; 95% CI, 1.04-2.6; P = 0.035) were found to be independently associated with inferior disease-free survival. No other clinical or pathologic variables predicted failure. Salvage laryngectomy after nonoperative treatment failure results in successful locoregional control rates and survival in the majority of patients failing initial therapy. This should temper enthusiasm for routine treatment intensification with postoperative re-irradiation and/or other systemic treatments for the vast majority of patients. Sarcomatoid pathology, LVSI, and an advanced initial stage are associated with inferior

    This paper reports on the importance of postoperative radiology. Most surgical procedures on the alimentary tract are successful, but postoperative complications remain a common occurrence. The radiologist must be familiar with a large variety of possible surgical complications, because it is this specialty that is most commonly called on to render a definitive diagnosis. The decision for reoperation, for instance, is usually based on results from radiologic imaging techniques. These now include ultrasonography, CT scanning, needle biopsy, and interventional techniques in addition to contrast studies and nuclear medicine investigation

    Cell salvage is commonly used as part of a blood conservation strategy. However concerns among clinicians exist about the efficacy of transfusion of washed cell salvage. We performed a meta-analysis of randomized controlled trials in which patients, scheduled for all types of surgery, were randomized to washed cell salvage or to a control group with no cell salvage. Data were independently extracted, risk ratio (RR), and weighted mean differences (WMD) with 95% confidence intervals (CIs) were calculated. Data were pooled using a random effects model. The primary endpoint was the number of patients exposed to allogeneic red blood cell (RBC) transfusion. Out of 1140 search results, a total of 47 trials were included. Overall, the use of washed cell salvage reduced the rate of exposure to allogeneic RBC transfusion by a relative 39% (RR = 0.61; 95% CI 0.57 to 0.65; P platelets, or rate of myocardial infarction and stroke. Washed cell salvage is efficacious in reducing the need for allogeneic RBC transfusion and risk of infection in surgery.

    This article aims at reviewing the currently available evidence about blood conservation strategies in cardiac surgery. Pre-operative anaemia and perioperative allogeneic blood transfusions are associated with worse outcomes after surgery. In addition, transfusions are a scarce and costly resource. As cardiac surgery accounts for a significant proportion of all blood products transfused, efforts should be made to decrease the risk of perioperative transfusion. Pre-operative strategies focus on the detection and treatment of anaemia. The management of haematological abnormalities, most frequently functional iron deficiency, is a matter for debate. However, iron supplementation therapy is increasingly commonly administered. Intra-operatively, antifibrinolytics should be routinely used, whereas the cardiopulmonary bypass strategy should be adapted to minimise haemodilution secondary to circuit priming. There is less evidence to recommend minimally invasive surgery. Cell salvage and point-of-care tests should also be a part of the routine care. Post-operatively, any unnecessary iatrogenic blood loss should be avoided. © 2017 British Blood Transfusion Society.

    Recurrent oropharyngeal squamous cell carcinoma causes great morbidity and mortality. This systematic review analyses survival outcomes following salvage surgery for recurrent oropharyngeal squamous cell carcinoma. A comprehensive search of various electronic databases was conducted. Studies included patients with recurrent or residual oropharyngeal squamous cell carcinoma treated with salvage surgery. Primary outcomes were survival rates following salvage surgery. Secondary outcomes included time to recurrence, staging at time of recurrence, post-operative complications, and factors associated with mortality and recurrence. Methodological appraisal and data extraction were conducted as per Joanna Briggs Institute methodology. Eighteen articles were included. The two- and five-year survival rates of the patients were 52 per cent and 30 per cent respectively. Improvements in treatment modalities for recurrent oropharyngeal squamous cell carcinoma were associated with improvements in two-year overall survival rates, with minimal change to five-year overall survival rates. Various factors were identified as being associated with long-term overall survival, thus assisting clinicians in patient counselling and selection for salvage surgery.

    Soft tissue sarcomas occur most commonly in the lower and upper extremities. The standard treatment is limb salvage surgery combined with radiotherapy. Postoperative radiotherapy is associated with wound complications. This systematic review aims to summarise the available evidence and review the literature of the last 10 years regarding postoperative wound complications in patients who had limb salvage surgical excision followed by direct closure vs flap coverage together with postoperative radiotherapy and to define the optimal timeframe for adjuvant radiotherapy after soft tissue sarcomas resection and flap reconstruction. A literature search was performed using PubMed. The following keywords were searched: limb salvage, limb-sparing, flaps, radiation therapy, radiation, irradiation, adjuvant radiotherapy, postoperative radiotherapy, radiation effects, wound healing, surgical wound infection, surgical wound dehiscence, wound healing, soft tissue sarcoma and neoplasms. In total, 1045 papers were retrieved. Thirty-seven articles were finally selected after screening of abstracts and applying dates and language filters and inclusion and exclusion criteria. Plastic surgery provides a vast number of reconstructive flap procedures that are directly linked to decreasing wound complications, especially with the expectant postoperative radiotherapy. This adjuvant radiotherapy is better administered in the first 3-6 weeks after reconstruction to allow timely wound healing and avoid local recurrence. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Breast-conserving surgery is a standard treatment for early breast cancer. For ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery, salvage mastectomy is the current standard surgical procedure. However, it is not rare for patients with IBTR who have received salvage mastectomy to develop local recurrence. In this study, we examined the risk factors of local recurrence after salvage mastectomy for IBTR. A total of 118 consecutive patients who had histologically confirmed IBTR without distant metastases and underwent salvage mastectomy without irradiation for IBTR between 1989 and 2008 were included from eight institutions in Japan. The risk factors of local recurrence were assessed. The median follow-up period from salvage mastectomy for IBTR was 4.6 years. Patients with pN2 or higher on diagnosis of the primary tumor showed significantly poorer local recurrence-free survival than those with pN0 or pN1 at primary tumor (p mastectomy for IBTR. Further research and validation studies are needed. (UMIN-CTR number UMIN000008136). Copyright © 2016 Elsevier Ltd. All rights reserved.

  19. Blood Conservation Strategies in Total Hip and Knee Arthroplasty

    Full Text Available Peri-operative blood management is one of a number of components important for successful patient care in total joint arthroplasty and surgeons should be proactive in its application. The aims of blood conservation are to reduce the risks of blood transfusion whilst at the same time maximizing haemaglobin in the post-operative period, thereby leading to a positive effect on early and long term outcomes and costs. An individualized strategy based on patient specific risk factors, anticipated blood loss and co-morbidities is useful in achieving this aim. Multiple blood conservation strategies are available in the pre-operative, intra-operative and post-operative periods and can be utilised either individually or in combination. Recent literature has highlighted the importance of identifying and correcting pre-operative anaemia, salvaging peri-operative red cells and the use of tranexamic acid in reducing blood loss. Given total hip and knee arthroplasty is an elective procedure, a zero allogenic blood transfusion rate should be the aim and an achievable goal.

    To assess feasibility, safety, and metabolic outcome of islet auto transplantation (IAT) in patients undergoing completion pancreatectomy because of sepsis or bleeding after pancreatic surgery. From November 2008 to October 2016, approximately 22 patients were candidates to salvage IAT during emergency relaparotomy because of postpancreatectomy sepsis (n = 11) or bleeding (n = 11). Feasibility, efficacy, and safety of salvage IAT were compared with those documented in a cohort of 36 patients who were candidate to simultaneous IAT during nonemergency preemptive completion pancreatectomy through the pancreaticoduodenectomy. The percentage of candidates that received the infusion of islets was significantly lower in salvage IAT than simultaneous IAT (59.1% vs 88.9%, P = 0.008), mainly because of a higher rate of inadequate islet preparations. Even if microbial contamination of islet preparation was significantly higher in candidates to salvage IAT than in those to simultaneous IAT (78.9% vs 20%, P < 0.001), there was no evidence of a higher rate of complications related to the procedure. Median follow-up was 5.45 ± 0.52 years. Four (36%) of 11 patients reached insulin independence, 6 patients (56%) had partial graft function, and 1 patient (9%) had primary graft nonfunction. At the last follow-up visit, median fasting C-peptide was 0.43 (0.19-0.93) ng/mL; median insulin requirement was 0.38 (0.04-0.5) U/kg per day, and median HbA1c was 6.6% (5.9%-8.1%). Overall mortality, in-hospital mortality, metabolic outcome, graft survival, and insulin-free survival after salvage IAT were not different from those documented after simultaneous IAT. Our data demonstrate the feasibility, efficacy, and safety of salvage IAT after relaparotomy.

    The incidence of post-operative complications and treatment results of 60 cases of hypopharynx carcinoma receiving laryngo-pharyngo-esophagectomy followed by reconstruction with jejunum after chemoradiotherapy (CRT) from 1997 to 2006 in 6 hospitals was analyzed. The overall complication rate was 57%. There were 3 cases with carotid artery rupture (5%), 4 with jejunum necrosis (6%), 6 with major salivary fistula (10%), 8 with minor salivary fistula (13%), 8 with abscess alone (13%), 3 with trachea stoma necrosis (5%), and 3 with skin flap necrosis (5%). The death rate due to surgical complications was 3% (2/60). When the cases were divided into two groups, namely the cases with fistula and the cases without fistula, the number of days that permitted drinking was 18.1 in the latter and 81.8 in the former. The 5-year overall survival rate among all cases was 37%. We found that salvage surgery after CRT was effective for recurrent cases. These findings suggest that reconstruction with jejunum is a suitable type of operation with better surgical results. Care is required to reduce the incidence of post-operative complications.

    As a rule, postoperative imaging is carried out after spinal interventions to document the exact position of the implant material. Imaging is absolutely necessary when new clinical symptoms occur postoperatively. In this case a rebleeding or an incorrect implant position abutting a root or the spinal cord must be proven. In addition to these immediately occurring postoperative clinical symptoms, there are a number of complications that can occur several days, weeks or even months later. These include the failed back surgery syndrome, implant loosening or breakage of the material and relapse of a disc herniation and spondylodiscitis. In addition to knowledge of the original clinical symptoms, it is also important to know the operation details, such as the access route and the material used. In almost all postoperative cases, imaging with contrast medium administration and corresponding correction of artefacts by the implant material, such as the dual energy technique, correction algorithms and the use of special magnetic resonance (MR) sequences are necessary. In order to correctly assess the postoperative imaging, knowledge of the surgical procedure and the previous clinical symptoms are mandatory besides special computed tomography (CT) techniques and MR sequences.

    In this study, we present the treatment results of salvage surgery in 34 patients with residual primary tumor or local relapse tumor in the hypopharynx and cervical esophagus after radiotherapy (15 patients) or chemoradiotherapy (19 patients) at the Division of Head and Neck Surgery, National Cancer Center Hospital East between 1997 and 2006. All patients underwent total pharyngolaryngoesophagectomy (TPLE) as salvage surgery. Among these patients, postoperative complication was observed in 11 patients (32.4%). Fisher's exact test revealed no significant difference in postoperative complication rate between the radiotherapy (RT) group and chemoradiotherapy (CRT) group. Tumors in the neck recurred in 10 patients (55.6%) after surgical resection. The tumor recurrence control rate for cervical lymph nodes was 84.7% for patients with clinically N0 disease after CRT who had not undergone neck dissection. The median survival time was 392 days. We consider that salvage surgery can he safely performed by considering the necessity and method of operation, and the outcome of patients receiving CRT would he improved by salvage surgery.

    Cognitive dysfunctions are relatively common in postoperative and critically ill patients. This complication not only compromises recovery after surgery, but, if persistent, it minimizes and compromises surgery itself. Risk factors of postoperative cognitive disorders can be divided into age and comorbidity dependent, and those related to anesthesia and surgery. Cardiovascular, orthopedic and urologic surgery carries high risk of postoperative cognitive dysfunction. It can also occur in other types of surgical treatment, especially in elderly. Among risk factors of cognitive disorders, associated with comorbidity, underlying psychiatric and neurological disorders, substance abuse and conditions with elevation of intracranial pressure are in the first place in postoperative patients. Preoperative and perioperative predisposing conditions for cognitive dysfunction and their incidence were described in our paper. These are: geriatric patients, patients with substance abuse, preexisting psychiatric or cognitive disorders, neurologic disease with high intracranial pressure, cerebrovascular insufficiency, epilepsia, preeclampsia, acute intermittent porphyria, operation type, brain hypoxia, changes in blood glucose level, electrolyte imbalance, anesthetic agents, adjuvant medication and intraoperative awareness. For each of these factors, evaluation, prevention and treatment strategies were suggested, with special regard on anesthetic technique.

    Of all surgical specialties, cardiac operations are most often associated with coagulopathy, blood loss, and the need for transfusions. This not only represents a major burden on blood procurement and banking organizations at all levels, but also constitutes a risk for each patient receiving allogeneic blood products. This paper reviews current non-pharmacological strategies aimed at decreasing blood use in patients undergoing cardiac surgery. The literature pertaining to each blood conservation strategy was searched, reviewed, and appraised. Meta- analyses were also consulted and their results complemented with subsequent reports when available. Preoperative autologous donation programs are effective in decreasing allogeneic transfusions, but are costly and applicable to elective patients only. Off-pump revascularization strategies also appear to decrease transfusion requirements in suitable patients. The effectiveness of acute normovolemic hemodilution, retrograde autologous priming, small volume cardiopulmonary bypass circuits, platelet-rich plasmapheresis, alternative heparin strategies, and postoperative cell salvage are more difficult to appraise as a high proportion of available studies suffer from lack of transfusion guidelines or the absence of blinding. Biological glues, surgical adhesives, and postoperative increases in positive end-expiratory pressure (PEEP) have no demonstrated efficacy. The applicability or effectiveness of many of these modalities remains controversial and more studies are needed before they may be employed routinely in cardiac surgical patients. The judicious use of rational transfusion guidelines may still be the simplest and most cost-effective means of blood conservation today.

    Full Text Available Abstract Background Polyamine synthesis produces methylthioadenosine, which has to be disposed of. The cell recycles it into methionine through methylthioribose (MTR. Very little was known about MTR recycling for methionine salvage in Bacillus subtilis. Results Using in silico genome analysis and transposon mutagenesis in B. subtilis we have experimentally uncovered the major steps of the dioxygen-dependent methionine salvage pathway, which, although similar to that found in Klebsiella pneumoniae, recruited for its implementation some entirely different proteins. The promoters of the genes have been identified by primer extension, and gene expression was analyzed by Northern blotting and lacZ reporter gene expression. Among the most remarkable discoveries in this pathway is the role of an analog of ribulose diphosphate carboxylase (Rubisco, the plant enzyme used in the Calvin cycle which recovers carbon dioxide from the atmosphere as a major step in MTR recycling. Conclusions A complete methionine salvage pathway exists in B. subtilis. This pathway is chemically similar to that in K. pneumoniae, but recruited different proteins to this purpose. In particular, a paralogue or Rubisco, MtnW, is used at one of the steps in the pathway. A major observation is that in the absence of MtnW, MTR becomes extremely toxic to the cell, opening an unexpected target for new antimicrobial drugs. In addition to methionine salvage, this pathway protects B. subtilis against dioxygen produced by its natural biotope, the surface of leaves (phylloplane.

    It is essential to preserve as many of the parathyroid glands, as possible, during surgery of the thyroid gland. This is achieved by visualizing them and by minimal handling of the glands. Truncal ligation of the inferior thyroid artery is quite safe. Capsular ligation of the branches of the artery is theoretically superior but requires a greater degree of skill and experience in thyroid surgery. It also puts the recurrent laryngeal nerve at a greater risk of injury. Calcitriol or 1.25 dihydroxy vitamin D is a very useful drug in managing patients with severe post-operative hypoparathyroidism

    Full Text Available Background: A rule called "30-min rule" defines that red cell unit cannot be used if it has been out of blood bank refrigerator for over 30 min. This rule is useful to guide initiation of transfusion, but is inadequate for deciding whether to reuse or discard units received-back at blood transfusion services (BTS. A simple cost-effective temperature-sensitive indicator was evaluated to decide upon reuse (cold chain was uninterrupted or discard (where cold chain was interrupted in a simulation exercise. Materials and Methods: Temperature-sensitive indicators TH-F™ that irreversibly changed color from white to red demonstrated that heat excursion has occurred and the cumulative temperature has exceeded 10°C for over 30 min, were used in outdated red cells for simulating units, which are not used and received-back. These units were also tagged with a standard temperature monitoring device, which was a re-usable credit card sized device, which would log the actual time and temperature. In few units percent hemolysis was also calculated. Results: Statistically insignificant elevation in average temperature was noted in 102 simulated units at the time of return to BTS (Δ 0.04°C, despite the fact that these units were in the transport box for over 4 h. The average supernatant hemoglobin in these units was 0.24%, much below the prescribed threshold. Conclusion: Transportation of blood in controlled conditions with temperature-sensitive indicator is a cost-effective model to save blood, a precious human resource.

    Blood transfusion is usually meant to lower morbidity and mortality rates. Allogenous blood transfusion implies certain risks that can be avoided by autologous blood transfusions techniques including: preoperatory autologous blood donation, acute normovolemic hemodilution, intraoperatory and postoperatory blood salvage. Preoperatory blood donation and acute normovolemic hemodilution are used for planned interventions with an estimated blood loss higher than 20% of blood volume. These methods imply Erythropoietin and iron treatment. Intraoperatory and postoperatory blood salvage is performed by personnel trained in blood donation, handling and storage. Autologous blood transfusions are used for certain surgical procedures that commonly require transfusions: orthopedic surgery, radical prostatectomy, cardiovascular surgery, organ transplantation. An alternative to allogenous blood transfusion is the use of artificial oxygen transporters: human or animal hemoglobin solutions or pefluorocarbonate solutions. These solutions do not require cross reactions, do not carry diseases and are generally well tolerated and easily stored in the operating room, ambulance and other transport means. They have however a slight degree of toxicity.

    The optimal timing of salvage radiotherapy for biochemical recurrence after radical prostatectomy is controversial. In particular, the prognostic significance of salvage radiotherapy delivered before a current definition of biochemical recurrence, i.e. ultra-early salvage radiotherapy, is unclear. We reviewed 76 patients with pT2-3N0M0 prostate cancer who underwent salvage radiotherapy for post-prostatectomy biochemical recurrence at the following three timings: ultra-early salvage radiotherapy (n = 20) delivered before meeting a current definition of biochemical recurrence (two consecutive prostate-specific antigen [PSA] values ≥0.2 ng/mL); early salvage radiotherapy (n = 40) delivered after meeting the definition but before PSA reached 0.5 ng/mL; and delayed salvage radiotherapy (n = 16) delivered after PSA reached 0.5 ng/mL. The primary endpoint was failure of salvage radiotherapy, defined as a PSA value ≥0.2 ng/mL. The log-rank test and Cox proportional hazards model were used for univariate and multivariate analyses, respectively. During the follow-up period (median: 70 months), four of 20 (20 %), nine of 40 (23 %) and seven of 16 (44 %) patients failed biochemically in the ultra-early, early and delayed salvage radiotherapy groups, respectively. On univariate analyses, the outcome of delayed salvage radiotherapy was worse than the others, while there was no significant difference between ultra-early and early groups. Multivariate analysis demonstrated the presence of Gleason pattern 5, perineural invasion and delayed salvage radiotherapy as independent predictors of poorer survival. No survival benefit of ultra-early salvage radiotherapy was demonstrated, whereas delayed salvage radiotherapy was associated with worse outcome as reported in previous studies. Our results may support the current recommendations that salvage radiotherapy should be undertaken after two consecutive PSA values ≥0.2 ng/mL and before reaching 0.5 ng/mL

    Full Text Available Traumatic brachial plexus injuries rarely recover spontaneously and if the window period for neurotisation has elapsed, the only option for restoration of function lies in a salvage procedure. Many such salvage procedures have been described in the literature with variable functional results. We report the case of a 16-year-old boy who presented after unsuccessful treatment for a complete brachial plexus injury; we performed a pectoralis major tendon transfer to attain elbow flexion. Postoperatively, the elbow was splinted with flexion at 100°. After 4 weeks of immobilization the splint was removed and the patient could actively flex his elbow from 30° to 100°.

    Objective: Developing strategies for transfusion-free live donor liver transplantation in Jehovah's Witness patients. Summary Background Data: Liver transplantation is the standard of care for patients with end-stage liver disease. A disproportionate increase in transplant candidates and an allocation policy restructuring, favoring patients with advanced disease, have led to longer waiting time and increased medical acuity for transplant recipients. Consequently, Jehovah's Witness patients, who refuse blood product transfusion, are usually excluded from liver transplantation. We combined blood augmentation and conservation practices with live donor liver transplantation (LDLT) to accomplish successful LDLT in Jehovah's Witness patients without blood products. Our algorithm provides broad possibilities for blood conservation for all surgical patients. Methods: From September 1998 until June 2001, 38 LDLTs were performed at Keck USC School of Medicine: 8 in Jehovah's Witness patients (transfusion-free group) and 30 in non-Jehovah's Witness patients (transfusion-eligible group). All transfusion-free patients underwent preoperative blood augmentation with erythropoietin, intraoperative cell salvage, and acute normovolemic hemodilution. These techniques were used in only 7%, 80%, and 10%, respectively, in transfusion-eligible patients. Perioperative clinical data and outcomes were retrospectively reviewed. Data from both groups were statistically analyzed. Results: Preoperative liver disease severity was similar in both groups; however, transfusion-free patients had significantly higher hematocrit levels following erythropoietin augmentation. Operative time, blood loss, and postoperative hematocrits were similar in both groups. No blood products were used in transfusion-free patients while 80% of transfusion-eligible patients received a median of 4.5+/− 3.5 units of packed red cell. ICU and total hospital stay were similar in both groups. The survival rate was 100% in

    The aim of study was to evaluate the effect of mechanical ventilation mode type, pressure-controlled ventilation (PCV), or volume-controlled ventilation (VCV) on intra- and postoperative surgical bleeding in patients undergoing posterior lumbar interbody fusion (PLIF) surgery. This was a prospective, randomized, single-blinded, and parallel study that included 56 patients undergoing PLIF and who were mechanically ventilated using PCV or VCV. A permuted block randomization was used with a computer-generated list. The hemodynamic and respiratory parameters were measured after anesthesia induction in supine position, 5 min after patients were changed from supine to prone position, at the time of skin closure, and 5 min after the patients were changed from prone to supine position. The amount of intraoperative surgical bleeding, fluid administration, urine output, and transfusion requirement were measured at the end of surgery. The amount of postoperative bleeding and transfusion requirement were recorded every 24 h for 72 h. The primary outcome was the amount of intraoperative surgical bleeding, and 56 patients were analyzed. The amount of intraoperative surgical bleeding was significantly less in the PCV group than that in the VCV group (median, 253.0 [interquartile range, 179.0 to 316.5] ml in PCV group vs. 382.5 [328.0 to 489.5] ml in VCV group; P patients undergoing PLIF, which may be related to lower intraoperative peak inspiratory pressure.

    Postoperative alterations in platelet function induced by cardiopulmonary bypass (CPB) are of importance. The effect on platelet aggregation of three different techniques for reducing blood consumption was studied in 30 patients undergoing elective aortocoronary bypass grafting from the beginning of anesthesia until the 1st postoperative day. The patients were randomly divided into three groups, in which 1) a cell separator was used during and after CPB; 2) a hemofiltration device was used; and 3) high-dose aprotinin was used in order to reduce the need of homologous blood. A fourth group undergoing neurosurgery procedures served as a control. Platelet aggregation induced by adenosine diphosphate (concentration 0.25, 0.50, 1.0, and 2.0 microM), collagen (4 microliters/ml), and epinephrine (25 microM) was determined by the turbidimetric method. Platelet aggregation was not significantly changed in the control group, indicating that the operation itself did not impair platelet function. At the end of the operation (after retransfusion of the salvaged pump blood), the maximum aggregation and maximum gradient of aggregation induced by all three inductors were most reduced (significantly) in the cell-separator patients. On the 1st postoperative day, platelet aggregation in the hemofiltration patients and the patients treated with aprotinin had normalized. Aggregation of patients pretreated with high-dose aprotinin was not different from that of the hemofiltration patients throughout the investigation. Blood loss was significantly highest in the cell-separator group (770 +/- 400 ml on the 1st postoperative day) but was not different between the hemofiltration (390 +/- 230 ml) and the aprotinin-treated patients (260 +/- 160 ml).(ABSTRACT TRUNCATED AT 250 WORDS)

    Differentiated thyroid carcinoma (DTC) in children and young adults is rare but often aggressive and in an advanced stage at diagnosis. In a cohort of young Belarusian patients with advanced DTC after Chernobyl we retrospectively studied parameters influencing the success of the postoperative {sup 131}I therapy. Included in the study were 136 patients (83 female, 53 male; median age 14.3 years, range 9.4-22.8 years) who had had total thyroidectomy in Belarus and subsequent {sup 131}I therapy and follow-up in Germany. Of the 136 patients, 34 were classified as M1 and 102 as M0 (N0 1, N1 101). The median weight-adjusted {sup 131}I activity administered after thyroid hormone withdrawal was 52 MBq/kg (range 24-74 MBq/kg). TNM stage, gender, administered activity, whole-body residence time and blood dose during ablation, Tg and TSH levels, date, and age at time of treatment were tested for their effect on the rate of complete remission (CR). CR was defined as a negative scan and a stimulated Tg level of <1 ng/ml at follow-up. CR was observed in 1 of 34 M1 and in 51 of 102 M0 patients after the first treatment. Multivariate analysis in the M0 group identified the Tg level (P < 0.0001 for log(Tg)) and the radiation absorbed dose to the blood (P < 0.001) as independent determinants; all other parameters were unimportant (P > 0.3). The regression model was able to correctly predict CR in 82 of 102 patients (80.4%). In children and young adults with advanced DTC, the rate of CR after postoperative {sup 131}I therapy is dependent on the preablative Tg level and the radiation absorbed dose to the blood. Though the present results must be confirmed in a prospective study, they imply that preablative dosimetry may improve rates of CR. (orig.)

    that is institution based, accepted by all health care providers, and that involves well thought out transfusion algorithms to guide transfusion decisions. Based on available evidence, institution-specific protocols should screen for high-risk patients, as blood conservation interventions are likely to be most productive for this high-risk subset. Available evidence-based blood conservation techniques include (1) drugs that increase preoperative blood volume (eg, erythropoietin) or decrease postoperative bleeding (eg, antifibrinolytics), (2) devices that conserve blood (eg, intraoperative blood salvage and blood sparing interventions), (3) interventions that protect the patient's own blood from the stress of operation (eg, autologous predonation and normovolemic hemodilution), (4) consensus, institution-specific blood transfusion algorithms supplemented with point-of-care testing, and most importantly, (5) a multimodality approach to blood conservation combining all of the above.

    Full Text Available Nicotinamide Adenine Dinucleotide (NAD levels are essential for cellular homeostasis and survival. Main sources of intracellular NAD are the salvage pathways from nicotinamide, where Nicotinamide phosphoribosyltransferases (NAMPTs and Nicotinamidases (PNCs have a key role. NAMPTs and PNCs are important in aging, infection and disease conditions such as diabetes and cancer. These enzymes have been considered redundant since either one or the other exists in each individual genome. The co-occurrence of NAMPT and PNC was only recently detected in invertebrates though no structural or functional characterization exists for them. Here, using expression and evolutionary analysis combined with homology modeling and protein-ligand docking, we show that both genes are expressed simultaneously in key species of major invertebrate branches and emphasize sequence and structural conservation patterns in metazoan NAMPT and PNC homologues. The results anticipate that NAMPTs and PNCs are simultaneously active, raising the possibility that NAD salvage pathways are not redundant as both are maintained to fulfill the requirement for NAD production in some species.

    veis intraoperatórios mais elevados de glicemia estão associados com maior morbidade no pós-operatório de cirurgia cardíaca pediátrica.BACKGROUND: Anesthesia for pediatric cardiac surgery is systematically performed in severely ill patients under abnormal physiological conditions. In the intraoperative period, there are significant variations in blood volume, body temperature, plasma composition, and tissue blood flow, in addition to activation of inflammation, with important consequences. Serial measurements of blood glucose levels can indicate states of exacerbation of the neuroendocrine-metabolic response to trauma, serving as prognostic markers of morbidity in that population. OBJECTIVE: To correlate perioperative blood glucose levels of children undergoing cardiac surgery with the occurrence of postoperative complications, and to compare intraoperative blood glucose levels according to perioperative conditions. METHODS: Information regarding the surgical/anesthetic procedure and perioperative conditions of patients was collected from the medical records. The mean perioperative blood glucose levels in the groups of patients with and without postoperative complications and the frequencies of perioperative conditions were compared by use of odds ratio and non-parametric univariate analyses. RESULTS: Higher intraoperative blood glucose levels were observed in individuals who had postoperative complications. Prematurity, age group, type of anesthesia, and character of the procedure did not influence the mean intraoperative blood glucose level. The use of extracorporeal circulation (ECC was associated with higher blood glucose levels during surgery. In procedures with ECC, higher blood glucose levels were observed in individuals who had infectious and cardiovascular complications. In surgeries without ECC, that association was observed with infectious and hematological complications. CONCLUSION: Higher intraoperative blood glucose levels are associated with higher morbidity

    This review attempts to outline the alternative measures and interventions used in bloodless surgery in the field of gynecologic oncology and demonstrate their effectiveness. Nowadays, as increasingly more patients are expressing their fears concerning the potential risks accompanying allogenic transfusion of blood products, putting the theory of bloodless surgery into practice seems to gaining greater acceptance. An increasing number of institutions appear to be successfully adopting approaches that minimize blood usage for all patients treated for gynecologic malignancies. Preoperative, intraoperative and postoperative measures are required, such as optimization of red blood cell mass, adequate preoperative plan and invasive hemostatic procedures, assisting anesthetic techniques, individualization of anemia tolerance, autologous blood donation, normovolemic hemodilution, intraoperative cell salvage and pharmacologic agents for controlling blood loss. An individualised management plan of experienced personnel adopting a multidisciplinary team approach should be available to establish non-blood management strategies, and not only on demand of the patient, in the field of gynecologic oncology with the use of drugs, devices and surgical-medical techniques.

    Full Text Available Abstract Background The thiomethyl group of S-adenosylmethionine is often recycled as methionine from methylthioadenosine. The corresponding pathway has been unravelled in Bacillus subtilis. However methylthioadenosine is subjected to alternative degradative pathways depending on the organism. Results This work uses genome in silico analysis to propose methionine salvage pathways for Klebsiella pneumoniae, Leptospira interrogans, Thermoanaerobacter tengcongensis and Xylella fastidiosa. Experiments performed with mutants of B. subtilis and Pseudomonas aeruginosa substantiate the hypotheses proposed. The enzymes that catalyze the reactions are recruited from a variety of origins. The first, ubiquitous, enzyme of the pathway, MtnA (methylthioribose-1-phosphate isomerase, belongs to a family of proteins related to eukaryotic intiation factor 2B alpha. mtnB codes for a methylthioribulose-1-phosphate dehydratase. Two reactions follow, that of an enolase and that of a phosphatase. While in B. subtilis this is performed by two distinct polypeptides, in the other organisms analyzed here an enolase-phosphatase yields 1,2-dihydroxy-3-keto-5-methylthiopentene. In the presence of dioxygen an aci-reductone dioxygenase yields the immediate precursor of methionine, ketomethylthiobutyrate. Under some conditions this enzyme produces carbon monoxide in B. subtilis, suggesting a route for a new gaseous mediator in bacteria. Ketomethylthiobutyrate is finally transaminated by an aminotransferase that exists usually as a broad specificity enzyme (often able to transaminate aromatic aminoacid keto-acid precursors or histidinol-phosphate. Conclusion A functional methionine salvage pathway was experimentally demonstrated, for the first time, in P. aeruginosa. Apparently, methionine salvage pathways are frequent in Bacteria (and in Eukarya, with recruitment of different polypeptides to perform the needed reactions (an ancestor of a translation initiation factor and Ru

    Transanal endoscopic microsurgery (TEM) allows locally complete resection of early rectal cancer as an alternative to conventional radical surgery. In case of unfavourable histology after TEM, or positive resection margins, salvage surgery can be performed. However, it is unclear if the results are equivalent to primary treatment with total mesorectal excision (TME). The aim of this retrospective study was to determine whether there is a difference in outcome between patients who underwent early salvage resection with TME after TEM, and those who underwent primary TME for rectal cancer. From 1997 to 2011, early salvage surgery with TME after TEM was performed in 25 patients in our institution. These patients were compared with 25 patients who underwent primary TME, matched according to gender, age (±2 years), cancer stage and operative procedure. Data were obtained from the patients' charts and reviewed retrospectively. No patients received preoperative chemotherapy. Perioperative data and oncological outcome were analysed. The Mann-Whitney U-test and Fisher's exact test were used to compare the results between the two groups. There was no significant difference between the two groups in median operating time (P = 0.39), median blood loss (P = 0.19) or intraoperative complications (P = 1.00). The 30-day mortality was 8 % (n = 2) among patients who underwent salvage TME after TEM, and no patients died in the primary TME group (P = 0.49). There was no significant difference between two groups of patients in the median number of harvested lymph nodes (P = 0.34), median circumferential resection margin (CRM) (P = 0.99) or the completeness of the mesorectal fascia plane. No local recurrences occurred among the patients with salvage TME, and there were 2 patients (8 %) with local recurrences among the patients with primary TME (P = 0.49). Distant metastasis occurred in one patient (4 %) after salvage TME and in 3 patients (12 %) with primary TME (P = 0.61). The median

    Full Text Available Located in a strategic position, that is between two great oceans and two land masses have made Indonesia a centre of international trade and shipping. In fact, 90% of international trades are carried out through the ocean. It is therefore crucial to assure that the activities in carrying goods across the ocean are incident free. However, if accident happens, assistance from professionals to preserve items of property is desirable. In such, salvage law emerged. This paper discusses comprehensively Indonesian salvage law within the framework of contemporary maritime law. While Indonesian maritime law is mostly based on its national law on the carriage of goods by the sea, in fact, the development of maritime law is highly affected by international practices which are largely based on international conventions and regulations. This research finds that while Indonesian salvage law can be found in Book II Chapter VII article 545-568k Wetboek Van Koophandel or known as Kitab Undang-undang Hukum Dagang (KUHD, which focused narrowly on the value of salved property as the primary measures of success, yet Indonesian salvage law has not been developed in accordance with current international salvage law, which adopted a broader and more balanced approached in both commercial and environmental aspects. Although it is believed that such approached is “culturally unrecognized” in Indonesia, this research argued that since Indonesian waters are part of international waters, all process by waters including salvage should confirm the relevant international practices and regulations. While Indonesia has taken out salvage law from KUHD and regulates it within Act Number 17/2008 on navigation, however, such act only provides one article for salvage stating that salvage will be regulates further by Ministry Regulation. Untill this paper was written no such government regulation produced yet by Indonesia. Since Indonesian waters is the centre of international

    Salvage laryngectomy (SL) is associated with high levels of morbidity. Rates of pharyngocutaneous fistulae (PCF) are as high as 35 % in some series. Patients at highest risk of such complications may be candidates for altered surgical management in terms of additional tissue transfer, or delayed tracheoesophageal puncture. This study investigates the relationship between the time from primary radiotherapy (RT) to salvage surgery and the development of PCF. 26 consecutive patients who underwent SL between 2000 and 2010 were identified from our institutional database. Demographic, staging, treatment and complication data were collected. Subgroup analysis was performed using the Student's t test or Mann-Whitney U test for continuous variables and either Chi-squared test or Fisher's Exact test for categorical variables. 26 patients underwent SL between October 2003 and July 2010. Of these, 15 (58 %) developed a PCF. On analysis of the time between pre-operative RT and surgery, a significant difference was seen, with a mean time of 19.5 months in those who developed a PCF versus 47.0 months in those who did not (p = 0.02). Patient characteristics, treatment, and pathology results were comparable between the two groups. There was no significant difference in distribution of the other covariates between the PCF and non-PCF groups. We reported a high rate of PCF and identified an association between PCF and a short time from primary treatment to salvage surgery. Identifying factors associated with higher rates of post-operative morbidity allows surgeons to adapt surgical planning in an attempt to minimize rates of PCF.

    The objective of this study was to determine the impact of salvage therapy for prostate-specific antigen (PSA) recurrence on the health-related quality of life (HRQOL) of patients after radical retropubic prostatectomy (RP). Between January 2000 and December 2003, a total of 249 patients who underwent RP were available for 2-year follow up. Of the respondents, 203 men did not show evidence of recurrence (group A), and 46 men received salvage hormonal therapy and/or radiotherapy after RP because of a rise in PSA (group B). The general and prostate-target HRQOL was assessed with the Medical Outcomes Study 36-Item Short Form and University of California, Los Angeles Prostate Cancer Index, respectively. Patients completed the HRQOL instruments by mail at baseline and at 24 months after RP. All of the patients completed both questionnaires. At baseline no significant differences were found between the two groups in any of the HRQOL domains. There were significant improvements in mental health and social function for the patients without biochemical recurrence postoperatively. Repeated measure analysis of variance (ANOVA) revealed significantly different patterns of alteration in several general HRQOL domains among the treatment groups. The urinary and bowel domains were equivalent between the two treatment groups at baseline and 24 months after RP. The patients treated with salvage hormonal therapy tended to show delayed recovery of sexual function. Using a self-administered questionnaire, biochemical recurrence following RP was found to impose a substantial burden in patients with localized prostate cancer. (author)

    Hemofiltration devices and the Cell Saver are the most often used techniques to reduce homologous blood requirements in cardiac surgery. In a controlled, randomized study, 105 patients underwent elective aortocoronary bypass grafting. Six different hemofilters (HF-80, HFT 14, CPB 7000, Cobe 1200, UF-205, BC-140) were tested and compared with the Cell Saver (Cell Saver 4) for blood concentration during and after cardiopulmonary bypass. Efficacy, practicality, and laboratory indices including coagulation variables were documented through the morning of the first postoperative day. The HF-80 and UF-205 were the most effective devices for blood concentration. At the end of the operation, the number of platelets was least reduced in these two groups (HF-80, -7%; UF-205, -6%). Moreover, both devices had a significantly higher filtration rate than the other hemofilters. Use of the Cell Saver resulted in the lowest values in coagulation variables (AT-III, fibrinogen, number of platelets) and the most pronounced deterioration in protein homeostasis (colloid osmotic pressure, albumin). In this group, the AT-III concentration was reduced until the morning of the first postoperative day. No negative effects were seen in regard to hemofiltration (free hemoglobin and polymorphonuclear elastase; the Cell Saver group had similar values for these variables). We conclude that blood salvage with hemofiltration devices is superior to that with the Cell Saver. There were, however, significant differences among the hemofilters. The HF-80 and UF-205 were the most effective devices in this study.

    A 48-year-old Japanese woman was diagnosed with Budd-Chiari syndrome and transferred for possible living donor liver transplantation (LDLT). Examinations before LDLT revealed that the recipient had anti-Jr a and preformed donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA). Rituximab was administrated at 16 days prior to the patient's scheduled LDLT for the prophylaxis of antibody-mediated rejection by DSA. The clinical significance of anti-Jr a has not been clearly established because of the rarity of this antibody, so we discussed blood transfusion strategy with the Department of Blood Transfusion Service and prepared for Jr a -negative packed red blood cells (RBCs). Intraoperative blood salvage was used during LDLT procedures to reduce the use of packed RBCs. Although post-transplantation graft function was excellent, a total of 44 U of Jr a -negative RBCs were transfused during the entire perioperative period. Because sufficient amounts of Jr a -negative packed RBCs were supplied, Jr a mismatched blood transfusion was avoided. The patient was discharged from our hospital on postoperative day 102 without clinical evidence of any blood transfusion-related adverse events. Although there are some controversies of blood transfusion related to anti-Jr a antibodies, the current strategies of blood transfusion for liver transplantation with anti-Jr a are as follows: (1) sufficient supply and transfusion of Jr a -negative matched packed RBCs and (2) application of intraoperative blood salvage to reduce the total amount of rare blood type RBCs. These strategies may be changed when the mechanism of anti-Jr a alloimmunization is fully understood in the future. Copyright © 2017 Elsevier Inc. All rights reserved.

    We have previously reported the importance of adequate and precise arterial anastomosis and the hypothesis that, up to subzone III, fingertip amputation salvage can be achieved on arterial anastomosis alone. These findings were reported during the meeting of the Japanese Society of Reconstructive Microsurgery. This is our follow-up report with insight and opinion on the limitations of complete fingertip amputation salvage on arterial anastomosis alone. We examined 67 fingers (59 patients) with fingertip amputations presenting to our hospital between January 2005 and December 2008. Amputation levels and whether these injuries received only arterial or both arterial and venous anastomoses were noted. Fisher exact test was used to examine statistical differences between the groups. Amputation levels were 11 in subzone I, 20 in subzone II, 17 in subzone III, and 19 in subzone IV. Successful replantation was achieved in 87% (58 of 67) of fingers. There was no statistically significant difference between fingers receiving arterial alone versus both anastomoses in amputations of subzones I, II, and III. We found that with proper postoperative congestion care, no statistically significant difference in replantation success of fingers receiving arterial anastomosis alone versus both arterial and venous were noted up to subzone III. However, in subzone IV, regardless of the postoperative congestion, compete necrosis rates are high; thus, it is speculated that a venous anastomosis is necessary for successful replantation. It is preferable to perform as many anastomoses as possible, but we believe that it is also desirable for the procedure to be fast and less invasive. In cases that have no adequate vein, fingertip replantation can be achieved on arterial anastomosis alone up to subzone III.

    Donor blood supplies are diminishing, becoming more costly and these transfusions lead to higher mortality in cardiac patients. The transfusion risks and the literature highlight the need for an alternative similar to cell salvage to be routinely considered. The Xtra is the first cell saver to be launched since 2001 and will undoubtedly initiate evolution towards the 'next generation' of cell savers. It is also the first to be launched in a new era where the demand for electronic perfusion data management (EPDM) has grown. The user interface (UI) was easy to use. The increased data entry options improved the quality of the recordable data. The integrated data management system (DMS) was comprehensive. Data was easy to manage and enabled central data compilation, which reduces repeated data, the risk of inconsistent data inventory and provides the potential for research and analyses. The haematocrit of the processed blood is a key quality indicator for cell salvage. The comparison of the manufacturer's integrated protocol, Popt, to our team's own protocol showed that Popt delivered a higher haematocrit on its '1st bowl' (59.1% compared to 57.3%) and its 'total process' end product haematocrit was 0.68% higher. The Popt cycle took an average of 330s, whereas our own settings completed in just over 300s. The Xtra is a device which will lead the evolution of 'next generation' cell saver technology. The user interface and data management system provide export options and the ability to record the level of data required for good EPDM. This is essential to 'future proof' cell salvage technology. The manufacturer's integrated protocol achieved a higher end product haematocrit than our perfusion team's best practice. The design of the Xtra is contemporary, but the DMS equips this cell saver for the new era that faces both Perfusion and Cardiac Surgery.

  2. Limb salvage treatment vs. amputation in sarcoma

    Full Text Available Many years ago the treatment of sarcoma was radiotherapy up to 2000-4000 rad. This treatment was very complicated, due to producing neoplasm after radiotherapy. By this method of treatment of osteosarcoma, the rate of survival became about 20% (two years. The second method of treatment was chemotherapy for a period of 2-5 weeks that amputation was performed afterwards. By chemotherapy, the rate of being alive reached up to 25-27% (five years. Right now, the best treatment for sarcoma is limb salvage. In our report, the chance of being alive in chondrosarcoma was about four years. This was nearly the same as that of the other institutes in the world especially in America, Europe, and Japan. The rate of recurrence was also more than that from different parts of the world. The survival rate in osteosarcomatic patients was about two years less for males the females, and it was more in tall people than short ones. The survival rate of the patients with giant cell tumor was more than osteosarcoma up to five years, and it has no recurrence or metastasis

    Outcome of salvage esophagectomy (SE), which was done due to rest development or recurrence after radical treatment of the esophageal cancer with radio- (RT) or chemoradio-therapy (CRT), was retrospectively studied and discussed. Subjects were 61 patients (M 54, F 7: average age, 63.5 y) with the cancer at Stage I- early IVB who had undergone radical CRT (35 cases) and RT (26) with >50 Gy, had no lymphatic and remote metastases at the diagnosis of the recurrence and then received SE and reconstruction surgery. Rough 5-year survival was found to be 29.2% in CRT group and 32.3% in RT. Operation-related death was 1 case (sepsis) and the rate of complication was slightly higher than the ordinary SE. Based on above outcome, discussion was made on following tasks and/or measures in authors' hospital: diagnostic means like the combination with positron emission tomography (PET), dose/regions of irradiation (dose to the heart and lung should be < TD 5/5=tolerance dose to be <5% incidence of adverse effect within 5 years) and of chemotherapy, decision of the irradiation area with consideration of SE afterward, careful surgery to reduce complication, and sufficient preoperative evaluation for radical surgery by images like PET/CT. Operation with consideration of these items conceivably makes SE safer. (R.T.)

    Blood transfusions have still been used as a standard therapy to treat severe anemia. Current evidences point to both excessive allogeneic blood consumption and decreased donations, which result in reduced stocks in blood banks. Several studies have increasingly suggested a more restrictive transfusion practice for blood products. Currently, a number of autologous blood conservation protocols in surgeries have been noted. We report a case of severe anemia with 2.9 g/dL hemoglobin, which was successfully handled without using the standard therapy to treat anemia with hemotransfusions. Such a case of severe anemia condition resulted after the patient was submitted to ascending aortic aneurism repair, valvar aortic replacement, reimplantation of right coronary ostium, followed by a coronary artery bypass grafting and several postoperative complications. The main clinical and surgical strategies used in this case to avoid blood transfusions were acute normovolemic hemodilution, intraoperative blood cell salvage, and meticulous hemostasis, beyond epsilon-aminocaproic acid, desmopressin, prothrombin complex concentrate, human fibrinogen concentrate, factor VIIa recombinant, erythropoietin and hyperoxic ventilation.

    Full Text Available Introduction: Limb salvage is considered as a more popular option in Indonesia, as amputation is considered offensive and taboo for many Indonesian cultures and societies. We evaluated the outcome of a series of LSSs with megaprosthesis and their challenges during treatments in Indonesia as the biggest archipelago nation in the world. Methods: Thirty-two patients originated from different islands in Indonesia with advanced lower extremity bone tumours were prospectively reviewed. Data was obtained from surgeries, which was conducted between 2011 and 2015 by two orthopaedic oncologist at Cipto Mangunkusumo Hospital. Functional outcome using musculoskeletal tumour society (MSTS score and oncological outcome were evaluated manually during every outpatient visit at 3, 6, 12 and 24 months. Results: Eight patients originate from Sumatra, one from Moluccas island, and twenty-three based in the Java island. We documented fourteen osteosarcomas, two cases of metastatic bone disease, fifteen giant cell tumours, and one chondromyxoid fibroma. Compared to preoperative score (mean 5.3, MSTS Score range 0–10, postoperative result (mean 25.2, MSTS Score range 53.3–90 at two year revealed 4.75 fold of improvement. Nearly half of the patient (40.6% showed excellent score (MSTS Score range 76.6–96.6 after one year. We reported several complications including: infection, knee dislocation, mechanism extensor disturbance, amputation, and nerve injury. Lower MSTS score was correlated with higher serum alkaline phosphatase (SAP (p = 0,031 and increase intraoperative blood loss (p = 0,033. Complication was found to be associated with tumours that underwent extensive soft tissue reconstruction procedure (p = 0,021. Conclusion: Functional outcome up to 24 months recorded satisfying result. Several complications occurred during our study also passed struggles for our patients during follow up care due to geographical challenges. Nevertheless, for carefully

    In non-small cell lung cancer (NSCLC), circulating tumor cells (CTC) are shed and circulate to the peripheral blood through the pulmonary vein. Previously, CTC count in pulmonary venous blood (pvCTC) was shown to significantly increase after surgical manipulation. Therefore, we assessed the correlation between the changes in the pvCTC count (ΔpvCTC) and clinical outcomes. Consecutive patients with peripheral-type, NSCLC, who underwent lobectomy or bi-lobectomy through open thoracotomy, were enrolled prospectively. Before and after lobectomy, 2.5 mL of blood was drawn from the associated lobar pulmonary vein (PV), and was served for the quantitative evaluation of CTC using the CellSearch ® system. The cut-off point of ΔpvCTC was determined according to clinical outcomes and ΔpvCTC using receiver operation characteristic (ROC) curve. Then the correlation between ΔpvCTC and clinical outcomes was evaluated by Kaplan-Meier analyses and log-rank test. In addition, the correlation between ΔpvCTC and perioperative variables was assessed. A total of 30 patients were enrolled, tumor recurrence occurred in 11 patients over a median follow-up of 64.4 months. Of these, 7 patients had distant metastasis and 4 had local recurrence. The median ΔpvCTC was 49 cells/2.5 mL, and pvCTC-count was increased during surgical manipulation in 24 patients (80%). We divided patients into two groups based on ΔpvCTC with the cut-off value as 119 cells/2.5 mL according to ROC curve. Significant shorter time to distant metastasis (TDM) (P=0.0123) was observed in high ΔpvCTC group (ΔpvCTC ≥119 cells/2.5 mL) than low ΔpvCTC group (ΔpvCTC <119 cells/ 2.5mL). Neither disease-free survival (DFS) nor overall survival (OS) was significantly correlated with ΔpvCTC. Increasing pvCTC count during surgical manipulation was significantly correlated with postoperative distant metastasis in completely resected NSCLC patients. Significant shorter TDM was observed in patient with high ΔpvCTC group.

    To describe the incidence and clinical outcomes of seminal vesicle invasion (SVI) at salvage radical prostatectomy (SRP) and to describe the accuracy of SV biopsy. As SRP is used after biochemical recurrence (BCR) of prostate cancer after radiotherapy (RT) to gain local oncological control. The SVs receive lower doses of radiation from external-beam RT (EBRT) to avoid rectal exposure and are not targeted with brachytherapy (BT) with low-risk prostate cancer. SRP was performed on 206 men with BCR after RT at a tertiary care institution between 1998 and 2011. Post-RT biopsy and SRP specimens were reviewed by a genitourinary pathologist. SVI was detected in 65 (32%) of 206 patients. No difference was found between EBRT alone (65% vs 63%) and BT (29% vs 31%) with or without EBRT in patients with SVI. Men with SVI had higher rates of cT3 disease (20% vs 8%) and Gleason score ≥ 8 at SRP (52% vs 21%). BCR-free survival at 5 years was 18% and 56% in patients with and without SVI (hazard ratio 2.85, 95% confidence interval 1.87-4.36, P < 0.001), yet the rate of local recurrence was low (11%). Prostate cancer was identified in nine of 18 patients who underwent SV biopsy and was the only location of prostate cancer in two patients. SVI is a prognostic indicator for BCR after SRP, but local recurrence in patients with SVI after SRP remains low. We recommend SV biopsy to improve staging and cancer detection in men with BCR after radiotherapy. © 2013 BJU International.

    In the past decades, wildfires around the world have continued to increase in size, severity, and cost. Major concerns after wildfires are the increased runoff and erosion due to loss of the protective forest floor layer, loss of water storage, and creation of water repellent soil conditions. Salvage logging is often a post-fire forest management action to recoup the economic loss of the burned timber, yet concerns arise on the impacts of this activity on water quality. Recently, several studies have been conducted to determine the effect of salvage logging on hillslope erosion. Logging skid trails have been cited as being the cause of high erosion during and after salvage operations. We investigated the impacts of adding operational logging slash to skid trails to reduce hillslope erosion after salvage operations on the 2015 North Star Fire, Washington. We implemented well-designed rapid response approach to compare slash treatment effectiveness by monitoring sediment yield and runoff response from hillslopes with a concentrated flow (rill) experiment. Various runoff amounts are incrementally added to 4 m hillslope plots with and without slash treatments. Our initial results suggest that adding logging slash increased ground cover significantly which contributed to an order of magnitude decrease in hillslope erosion. Integrating erosion mitigation strategies into salvage logging operations should be commonplace when hillslope erosion is a concern.

    Korean Sewol is successfully lifted up with the strand jack system based on twin barges. During the salvage operation, two barges and Sewol encounter offshore environmental conditions of wave, current and wind. It is inevitable that the relative motions among the three bodies are coupled with the sling tensions, which may cause big dynamic loads for the lifting system. During the project engineering phase and the site operation, it is necessary to build up a simulation model that can precisely generate the coupled responses in order to define a suitable weather window and monitor risks for the salvage operation. A special method for calculating multibody coupled responses is introduced into Sewol salvage project. Each body's hydrodynamic force and moment in multibody configuration is calculated in the way that one body is treated as freely moving in space, while other bodies are set as fixed globally. The hydrodynamic force and moment are then applied into a numerical simulation model with some calibration coefficients being inserted. These coefficients are calibrated with the model test results. The simulation model built up this way can predict coupled responses with the similar accuracy as the model test and full scale measurement, and particularly generate multibody shielding effects. Site measured responses and the responses only resulted from from the simulation keep project management simultaneously to judge risks of each salvage stage, which are important for success of Sewol salvage.

    Outcomes of arthroscopic superior labral anterior-posterior (SLAP) repairs have been well reported with generally favorable outcomes. Unfortunately, a percentage of patients remain dissatisfied or suffer further injury after SLAP repair and may seek additional treatment. The purpose of this study was to evaluate the surgical outcomes of biceps tenodesis for failed SLAP repairs. A retrospective review of all patients undergoing biceps tenodesis was completed. Inclusion criteria were previous SLAP repair and subsequent revision biceps tenodesis. Exclusion criteria were additional shoulder procedures including rotator cuff repair, instability procedures, and preoperative frozen shoulder. Objective outcomes were postoperative assessments with Constant score, American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation, Simple Shoulder Test, and Veterans RAND 36-Item Health Survey. Physical examination was conducted to determine postoperative range of motion and strength compared with the nonoperative shoulder. A cohort of 24 patients was identified, and of these, 17 patients (71%) completed the study at 2 years' follow-up. The average postoperative Constant score was 84.4; American Shoulder and Elbow Surgeons score, 75.5; Single Assessment Numeric Evaluation score, 73.1%; Simple Shoulder Test score, 9.2; and Veterans RAND 36-Item Health Survey score, 76.1. Postoperative range of motion of the operative shoulder returned to near that of the asymptomatic nonoperative shoulder. Workers' compensation status led to inferior results. Options for patients with a failed prior SLAP repair are limited. As a salvage operation for failed SLAP repair, biceps tenodesis serves the majority of patients well, with favorable outcomes by validated measures and excellent shoulder range of motion and elbow strength at 2 years' follow-up. Workers' compensation status may predispose patients to poorer outcomes. Copyright © 2014 Journal of Shoulder and Elbow Surgery Board

    Glioblastoma multiforme (GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM (rGBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery (GKRS) salvage therapy. Following a PubMed search for studies using GKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rGBM treatment. In this review, we compare Overall survival following diagnosis, Overall survival following salvage treatment, Progression-free survival, Time to recurrence, Local tumor control, and adverse radiation effects. This report discusses results for rGBM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates (from diagnosis, range: 16.7-33.2 mo; from salvage, range: 9-17.9 mo). Three studies identified median progression-free survival (range: 4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects (range: 0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rGBM patient. However, there needs to be a randomized clinical trial to test GKRS for rGBM before the possibility of selection bias can be dismissed. PMID:24829861

    Full Text Available Abstract Background Degenerative spinal stenosis and instability requiring multilevel spine surgery has been associated with large blood losses. Factors that affect perioperative blood loss include time of surgery, surgical procedure, patient height, combined anterior/posterior approaches, number of levels fused, blood salvage techniques, and the use of anti-fibrinolytic medications. This study was done to evaluate the efficacy of tranexamic acid in reducing blood loss in spine surgery. Methods This retrospective case control study includes 97 patients who had to undergo surgery because of degenerative lumbar spinal stenosis and instability. All operations included spinal decompression, interbody fusion and posterior instrumentation (4-5 segments. Forty-six patients received 1 g tranexamic acid intravenous, preoperative and six hours and twelve hours postoperative; 51 patients without tranexamic acid administration were evaluated as a control group. Based on the records, the intra- and postoperative blood losses were measured by evaluating the drainage and cell saver systems 6, 12 and 24 hours post operation. Additionally, hemoglobin concentration and platelet concentration were reviewed. Furthermore, the number of red cell transfusions given and complications associated with tranexamic acid were assessed. Results The postoperative hemoglobin concentration demonstrated a statistically significant difference with a p value of 0.0130 showing superiority for tranexamic acid use (tranexamic acid group: 11.08 g/dl, SD: 1.68; control group: 10.29 g/dl, SD: 1.39. The intraoperative cell saver volume and drainage volume after 24 h demonstrated a significant difference as well, which indicates a less blood loss in the tranexamic acid group than the control group. The postoperative drainage volume at12 hours showed no significant differences; nor did the platelet concentration Allogenic blood transfusion (two red cell units was needed for eight patients

    Postpartum hemorrhage (PPH) is a leading contributor to maternal morbidity and mortality in the United States and globally. Although the rate of PPH is generally decreasing nationally, severity of PPH appears to be increasing, potentially related to the various comorbidities associated with women of childbearing age. There is increasing evidence of risks associated with allogeneic blood transfusion, which has historically been the classic therapeutic approach for treatment to PPH. Pregnant women are particularly susceptible to the implications of sensitization to red cell antigens, a common sequela to allogenic blood transfusion. Autologous blood transfusion eliminates the potential of communicable disease transmission as well as the conceivable threat of a blood transfusion reaction. Recent technological advances allow cell salvage coupled with the use of a leukocyte filter to be used as an alternative approach for improving the outcome for women experiencing a PPH. Modest changes in standard operating procedure and continued training in use and application of cell salvaged blood may assist in minimizing negative outcomes from PPH. Salvaged blood has been demonstrated to be at least equal and often superior to banked blood. We discuss nursing implications for application of this technology for women with PPH. Continued research is warranted to evaluate the impact that application of cell salvage with filtration has on the patient experiencing a PPH.

  18. Understanding postoperative fatigue.

    Rose, E A; King, T C

    1978-07-01

    Performance characteristics of the central nervous, cardiovascular, respiratory and muscular systems in man postoperatively have received little investigative attention, despite the well known syndrome of postoperative fatigue. The impairmen in perception and psychomotor skills that has been shown to result from caloric restriction, bedrest, sedation and sleep deprivation suggests that a similar deficit may occur after surgical procedures. After a simple elective surgical procedure, maximal oxygen uptake decreases and the adaptability of heart rate to submaximal workloads is impaired. Similar deleterious effects on cardiorespiratory performance have been documented with starvation and bedrest; an understanding of cardiorespiratory performance postoperatively awaits further investigation. Maximal muscular force of contraction is also impaired by caloric restriction and bedrest, suggesting that similar effects may be seen in the postoperative state, although this has not been studied. A better understanding of the syndrome of postoperative fatigue could be achieved by a descriptive analysis of physiologic performance postoperatively. Such descriptive data could form the basis for objective evaluation of therapeutic measures intended to improve performance, such as nutritional supplementation and pharmacologic intervention. The observation that exercise with the patient in the supine position may decrease the impairment in maximal aerobic power otherwise expected in immobilized patients suggests that controlled exercise therapy may be of value in reducing physiologic impairment postoperatively.

    Postoperative peritonitis is still a life-threatening complication after abdominal surgery and approximately 10,000 patients annually develop postoperative peritonitis in Germany. Early recognition and diagnosis before the onset of sepsis has remained a clinical challenge as no single specific screening test is available. The aim of therapy is a rapid and effective control of the source of infection and antimicrobial therapy. After diagnosis of diffuse postoperative peritonitis surgical revision is usually inevitable after intestinal interventions. Peritonitis after liver, biliary or pancreatic surgery is managed as a rule by means of differentiated therapy approaches depending on the severity.

    Full Text Available An unusual penetrating chest injury was caused by high velocity road traffic accident. An 18-year-old had a four wheeler accident and was brought in emergency department with a ′bamboo′ stick on the left side chest exiting through back. After the stabilization of vital parameters, an inter-costal tube drainage was done on the left side. Except the minor brochopleural fistula which healed by 10 th day, his recovery was uneventful. The outcome was consistent with current aggressive management of penetrating chest injuries. Management of penetrating chest injury involving pulmonary trauma is based on three principles. One is stabilization of hemodynamics of patient with proper clinical evaluation. Second, a mere intercostal tube drainage sufficient for majority of the cases. Third, post-operative active as well as passive physiotherapy is necessary for speedy recovery.

    2018-04-01

    Objectives  Ideal treatment of craniopharyngiomas is still controversial. Radiotherapy (RT) is considered effective for recurrences or after subtotal tumor removal (STR). About 40 to 50% of patients may experience tumor cyst expansion soon after RT; in these cases, the role of salvage surgery is debated. Design  Operative video. Setting  Tertiary care center. Participants  An 11-year-old boy diagnosed with persistent craniopharyngioma. In 2015, the patient underwent right frontotemporal craniotomy for STR at another center, complicated by panhypopituitarism. Two years later, fractionated 54-Gy RT was performed on growing residual tumor. After 3 months, he was admitted to our hospital due to persistent malaise, vomiting, pulsating headache, and epistaxis. Ophthalmologic evaluation evidenced left homonymous hemianopsia. Results  A contrast-enhanced magnetic resonance imaging (MRI) showed a 27-mm cystic component enlarging from the cranial end of the persistent craniopharyngioma lesion, extending into the third ventricle. Biventricular hydrocephalus and brain midline shift to the right were present. Compared with the early post-RT MRI, the cystic component of the tumor demonstrated growth. The patient underwent external ventricular drainage placement for emergent treatment of hydrocephalus and endoscopic transsphenoidal surgery. After cystic content drainage, the lesion was completely removed with its capsule. A "gasket seal" technique was performed for skull base reconstruction, with autologous fascia lata, septal bone, and mucoperiosteum from inferior turbinate. Histologic examination confirmed the craniopharyngioma diagnosis. Postoperative MRI showed resolution of the hydrocephalus and complete tumor removal. Conclusion  Although shrinkage of cystic components of craniopharyngioma residuals may occur within 5 to 6 months after RT, salvage surgery is indicated in symptomatic patients.

    Purpose: To compare outcomes of salvage mastectomy (SM) and salvage breast-conserving surgery (SBCS) and study the feasibility of SBCS. Methods and Materials: Of 2,038 patients treated with breast-conserving therapy at Yale-New Haven Hospital before 1999, 166 sustained an ipsilateral breast tumor recurrence (IBTR). Outcomes and prognostic factors of patients treated with SM or SBCS were compared. Patients were considered amenable to SBCS if the recurrence was localized on mammogram and physical examination, and had pathologic size <3 cm, confined to the biopsy site, without skin or lymphovascular invasion, and with ≤3 positive nodes. Results: Of the 146 patients definitively managed at IBTR, surgery was SM (n = 116) or SBCS (n 30). The median length of follow-up after IBTR was 13.8 years. The SM and SBCS cohorts had no significant differences, except at IBTR the SM cohort had a greater tumor size (p = 0.049). Of the SM cohort, 65.5% were considered appropriate for SBCS, and a localized relapse was predicted by estrogen-receptor positive, diploid, and detection of recurrence by mammogram. Multicentric disease correlated with BRCA1/2 mutation, estrogen-receptor negative, lymph node positive at relapse, and detection of recurrence by physical examination. Survival after IBTR was 64.5% at 10 years, with no significant difference between SM (65.7%) and SBCS (58.0%). Only 2 patients in the SBCS cohort subsequently had a second IBTR, and were salvaged with mastectomy. Conclusions: While mastectomy is considered the standard surgical salvage of IBTR, SBCS is feasible and prognostic factors are related to favorable tumor biology and early detection. Patients with BRCA1/2 germline mutations may be less appropriate for SBCS, as multicentric disease was more prevalent. Patients who underwent SBCS had comparable outcomes as those who underwent SM, but remain at continued risk for IBTR. A prospective trial evaluating repeat lumpectomy and partial breast reirradiation is

    Gastric surgery may be performed for the treatment of a variety of benign and malignant diseases of the upper gastrointestinal tract, including peptic ulcers and gastric carcinoma. Radiographic studies with water-soluble contrast agents often are obtained to rule out leaks, obstruction, or other acute complications during the early postoperative period. Barium studies may also be obtained to evaluate for anastomotic strictures or ulcers, bile reflux gastritis, recurrent tumor, or other chronic complications during the late postoperative period. Cross-sectional imaging studies such as CT are also helpful for detecting abscesses or other postoperative collections, recurrent or metastatic tumor, or less common complications such as afferent loop syndrome or gastrojejunal intussusception. It is important for radiologists to be familiar not only with the radiographic findings associated with these various abnormalities but also with the normal appearances of the postoperative stomach on radiographic examinations, so that such appearances are not mistaken for pseudoleaks or other postoperative complications. The purpose of this article is to describe the normal postsurgical anatomy after the most commonly performed operations (including partial gastrectomy, esophagogastrectomy and gastric pull-through, and total gastrectomy and esophagojejunostomy) and to review the acute and chronic complications, normal postoperative findings, and major abnormalities detected on radiographic examinations in these patients.

    Full Text Available Background. Many studies have reported on the surgical outcomes of soft tissue sarcoma. However, there was no longitudinal cohort study. Because time is the most valuable factor for functional recovery, adjusting time value was the key for finding the causal relationship between other risk factors and postoperative function. Therefore, existing cross-sectional studies can neither fully explain the causal relationship between the risk factors and the functional score nor predict functional recovery. The aim of this study was to determine important predictive factors that affect postoperative functional outcomes and longitudinal changes in functional outcomes in patients who had undergone limb-sparing surgery (LSS for soft tissue sarcoma (STS. Methods. Between January 2008 and December 2014, we retrospectively enrolled 150 patients who had undergone LSS for STS and had been assessed for postoperative functional outcomes with questionnaires. To evaluate functional outcomes, we used the Musculoskeletal Tumor Society (MSTS score and Toronto Extremity Salvage Score (TESS. Multivariate generalized estimating equation (GEE analysis was used to identify the predictive factors, including size, stage, and anatomic location of tumor, bone resection, flap reconstruction, age, and time after surgery. Each continuous variable such as age and time after surgery was explored for statistically significant cutoff points using the Wilcoxon rank sum test. Results. Functional scores significantly improved until the second year after surgery and plateaued for the rest of the 5-year period. Age p<0.0001, bone resection p=0.0004, and time after surgery p<0.0001 were identified as significant predictive factors. The functional score was significantly higher in patients younger than 47 years old. Conclusions. Functional outcomes can improve until the second year after surgery. Patients who were older than 47 and underwent bone resection may have poor final functional

    This retrospective analysis describes blood conservation strategies and overall consumption of red blood cells (RBCs), fresh-frozen plasma (FFP), and platelet (PLT) concentrates during nonaortic cardiac surgery with cardiopulmonary bypass (CPB) in a tertiary hospital over a 10-year period. Study variables of 6026 patients that underwent cardiac surgery between 2002 and 2011 were incorporated in the database and included hemoglobin (Hb), lowest temperature, CPB duration, 24-hour blood loss, fluid balance, and overall transfusion requirements. Between 2002 and 2011, the lowest intraoperative Hb levels and temperature increased from 8.5 ± 1.2 to 10.4 ± 1.4 g/dL and from 32 ± 2 to 34 ± 1°C, respectively. In addition to the steep decrease in the postoperative fluid balance over time, a reduction in 24-hour blood loss from 815 ± 588 mL (2002) to 590 ± 438 mL (2011) was observed. These changes were paralleled by a 28% reduction in overall RBC transfusion from 1443 units in 2002 to 1038 in 2011. While RBC transfusion decreased over time, there was no significant change in the use of FFP or PLT concentrate transfusion. The probability to receive RBC transfusion increased after cessation of aprotinin, but reduced after routine cell salvage in all operations. This institutional report shows a large reduction in blood loss and transfusion requirements in cardiac surgery over a 10-year period. This reduction is most probably attributed to structural cell salvage, reduced intraoperative fluid volumes, and the increase in the lowest intraoperative body temperature. © 2013 AABB.

  11. Psychosocial reactions to upper extremity limb salvage: A case series.

    Case series. A salvaged limb is one that has undergone a major traumatic injury, followed by repeated surgical attempts in order to avoid amputation. Psychological recovery for individuals with lower extremity limb salvage has been examined in a number of studies. However, psychosocial reactions for individuals with upper extremity (UE) limb salvage are understudied in the literature. The purpose of this study was to explore the process of psychosocial adaptation for 3 trauma cases after UE limb salvage. The Reactions to Impairment and Disability Inventory was used to assess psychosocial adaptation. Physical function outcomes (pain, range of motion, edema, sensation, and dexterity) are presented. The Disabilities of the Arm, Shoulder, and Hand measure was used to assess perceived disability. Medical and rehabilitation history are discussed for each case, in order to provide in-depth understanding of the impact of these injuries. Reactions to injury varied across the cases; however, outcomes suggest that psychosocial adaptation may be influenced by the experience of pain, the ability to participate in valued roles and activities, and having a supportive social network. For this population, therapists may consider emphasizing pain management, focusing on client-centered goals and interventions, and facilitating peer support. Providers should closely monitor patients for signs of poor adaptation, such as hand-hiding behaviors. This study is among the first to examine psychological outcomes for the UE limb salvage population. Future research would be beneficial to provide deeper understanding of the psychosocial challenges for these individuals. Copyright © 2017 Hanley & Belfus. Published by Elsevier Inc.

    The effectiveness of cryotherapy on joint arthroplasty recovery remains controversial. This systematic review was conducted to assess the effectiveness of cryotherapy in patients after joint arthroplasty. Comprehensive literature searches of several databases including Cochrane Library (2013), MEDLINE (1950-2013), and Embase (1980-2013) were performed. We sought randomised controlled trials that compared the experimental group received any form of cryotherapy with any control group after joint arthroplasty. The main outcomes were postoperative blood loss, adverse events, and pain. Analyses were performed with Revman 5.0. Results were shown as mean differences (MD) and standard deviations or as risk difference and 95 % confidence intervals (CIs). Ten trials comprised 660 total knee arthroplastys and three trials comprised 122 total hip arthroplastys (THAs) met the inclusion criteria. Blood loss was significantly decreased by cryotherapy (MD = -109.68; 95 % CI -210.92 to -8.44; P = 0.03). Cryotherapy did not increase the risk of adverse effect (n.s.). Cryotherapy decreased pain at the second day of postoperative (MD = -1.32; 95 % CI -2.37 to -0.27; P = 0.0003), but did not decreased pain at the first and third day of postoperative (n.s.). Cryotherapy appears effective in these selected patients after joint arthroplasty. The benefits of cryotherapy on blood loss after joint arthroplasty were obvious. However, the subgroup analysis indicated that cryotherapy did not decreased blood loss after THA. Cryotherapy did not increase the risk of adverse effect. Cryotherapy decreased pain at the second day of postoperative, but did not decreased pain at the first and third day of postoperative. II.

    Developing strategies for transfusion-free live donor liver transplantation in Jehovah's Witness patients. Liver transplantation is the standard of care for patients with end-stage liver disease. A disproportionate increase in transplant candidates and an allocation policy restructuring, favoring patients with advanced disease, have led to longer waiting time and increased medical acuity for transplant recipients. Consequently, Jehovah's Witness patients, who refuse blood product transfusion, are usually excluded from liver transplantation. We combined blood augmentation and conservation practices with live donor liver transplantation (LDLT) to accomplish successful LDLT in Jehovah's Witness patients without blood products. Our algorithm provides broad possibilities for blood conservation for all surgical patients. From September 1998 until June 2001, 38 LDLTs were performed at Keck USC School of Medicine: 8 in Jehovah's Witness patients (transfusion-free group) and 30 in non-Jehovah's Witness patients (transfusion-eligible group). All transfusion-free patients underwent preoperative blood augmentation with erythropoietin, intraoperative cell salvage, and acute normovolemic hemodilution. These techniques were used in only 7%, 80%, and 10%, respectively, in transfusion-eligible patients. Perioperative clinical data and outcomes were retrospectively reviewed. Data from both groups were statistically analyzed. Preoperative liver disease severity was similar in both groups; however, transfusion-free patients had significantly higher hematocrit levels following erythropoietin augmentation. Operative time, blood loss, and postoperative hematocrits were similar in both groups. No blood products were used in transfusion-free patients while 80% of transfusion-eligible patients received a median of 4.5+/- 3.5 units of packed red cell. ICU and total hospital stay were similar in both groups. The survival rate was 100% in transfusion-free patients and 90% in transfusion

    Blood transfusion is not without risk. Although the risks of HIV and hepatitis transmission have diminished, haemovigilance programs highlight that other significant transfusion hazards remain. Sepsis from bacterial contamination is the most common residual infectious hazard in developed countries, and events due to clerical error are problematic. Unnecessary transfusions should be avoided. New national guidelines on patient blood management (PBM) emphasise holistic approaches, including strategies to reduce transfusion requirements. Perioperative PBM should incorporate preoperative haemoglobin and medication optimisation, intraoperative blood conservation, and consideration of restrictive postoperative transfusion and cell-salvage techniques. When massive transfusion is required, hospitals should implement massive transfusion protocols. These protocols reduce mortality, improve communication and facilitate adequate provision of blood products. They should include multidisciplinary team involvement and guidelines for use of blood components and adjunctive agents. Although fresh frozen plasma to red blood cell and platelet to red blood cell ratios of ≥ 1 : 2 appear to reduce mortality in trauma patients who receive massive transfusion, there is insufficient evidence to recommend specific ratios. Systematic reviews have found no significant benefit of recombinant activated factor VII in critical bleeding, and an increase in thromboembolic events; specialist haematology advice is therefore recommended when considering use of this agent. The National Safety and Quality Health Service Standards address use of blood and blood products, and provide important transfusion principles for adoption by all clinicians. Storage of red cells in additive solution results in changes, known as the "storage lesion", and studies to determine the clinical effect of the age of blood at transfusion are ongoing.

  15. Risk Factors for Postoperative Fibrinogen Deficiency after Surgical Removal of Intracranial Tumors.

    Directory of Open Access Journals (Sweden)

    Naili Wei

    Full Text Available Higher levels of fibrinogen, a critical element in hemostasis, are associated with increased postoperative survival rates, especially for patients with massive operative blood loss. Fibrinogen deficiency after surgical management of intracranial tumors may result in postoperative intracranial bleeding and severely worsen patient outcomes. However, no previous studies have systematically identified factors associated with postoperative fibrinogen deficiency. In this study, we retrospectively analyzed data from patients who underwent surgical removal of intracranial tumors in Beijing Tiantan Hospital date from 1/1/2013to12/31/2013. The present study found that patients with postoperative fibrinogen deficiency experienced more operative blood loss and a higher rate of postoperative intracranial hematoma, and they were given more blood transfusions, more plasma transfusions, and were administered larger doses of hemocoagulase compared with patients without postoperative fibrinogen deficiency. Likewise, patients with postoperative fibrinogen deficiency had poorer extended Glasgow Outcome Scale (GOSe, longer hospital stays, and greater hospital expenses than patients without postoperative fibrinogen deficiency. Further, we assessed a comprehensive set of risk factors associated with postoperative fibrinogen deficiency via multiple linear regression. We found that body mass index (BMI, the occurrence of postoperative intracranial hematoma, and administration of hemocoagulasewere positively associated with preoperative-to-postoperative plasma fibrinogen consumption; presenting with a malignant tumor was negatively associated with fibrinogen consumption. Contrary to what might be expected, intraoperative blood loss, the need for blood transfusion, and the need for plasma transfusion were not associated with plasma fibrinogen consumption. Considering our findings together, we concluded that postoperative fibrinogen deficiency is closely associated with

    Full Text Available Postoperative spinal wound infection is a potentially devastating complication after operative spinal procedures. Despite the utilization of perioperative prophylactic antibiotics in recent years and improvements in surgical technique and postoperative care, wound infection continues to compromise patients’ outcome after spinal surgery. In the modern era of pending health care reform with increasing financial constraints, the financial burden of post-operative spinal infections also deserves consideration. The aim of our work is to give to the reader an updated review of the latest achievements in prevention, risk factors, diagnosis, microbiology and treatment of post-operative spinal wound infections. A review of the scientific literature was carried out using electronic medical databases Pubmed, Google Scholar, Web of Science and Scopus for the years 1973-2012 to obtain access to all publications involving the incidence, risk factors, prevention, diagnosis, treatment of postoperative spinal wound infections. We initially identified 119 studies; of these 60 were selected. Despite all the measures intended to reduce the incidence of surgical site infections in spine surgery, these remain a common and potentially dangerous complication.

    Purpose: Management of follicular lymphoma after chemotherapy failure has been controversial and has ranged from watchful waiting to high-dose chemotherapy. High-dose chemotherapy with bone marrow reconstitution may produce clinical and molecular complete responses at the risk of serious morbidity and mortality. It has been previously reported that central lymphatic irradiation (CLI) can achieve long-term relapse-free survival in patients with Stage I, II, or III follicular lymphoma. Therefore, we investigated the feasibility of treating patients in whom front-line chemotherapy failed with salvage CLI instead of instituting more intensive chemotherapy. Methods and Materials: Salvage CLI with curative intent for patients with follicular lymphoma was started at The University of Texas M. D. Anderson Cancer Center in 1992. Eleven patients whose disease showed poor response to or relapsed after chemotherapy were managed with this approach. The median age of the patients was 61 years. Criteria for exclusion included bone marrow involvement or other evidence of Ann Arbor Stage IV disease at any time during the course of the disease. Overall survival and relapse-free survival were calculated from the first day of CLI. Results: Ten patients were alive at a median follow-up of 25 months (range 9-73 months). The treatment was well tolerated in general. Two patients could not complete CLI: one 75-year-old patient owing to prolonged platelet count depression and deterioration in general medical condition, and a 66-year-old patient because of exacerbation of preexisting pancytopenia and worsening of heart disease. Everyone who completed CLI remains in remission at the time of this report, except for one patient who had a relapse in the right lacrimal gland at 32 months. This patient was treated with local radiation therapy and is free of disease. Eventual recovery of the blood counts was observed for the patients who completed CLI. Conclusion: These results demonstrate for the

    Purpose: To evaluate the role of postoperative radiotherapy in the management of primary or recurrent intracranial meningiomas. Methods and Materials: A retrospective review of 34 intracranial meningioma patients referred to the Yonsei Cancer Center for postoperative radiotherapy between 1981 and 1990 was undertaken. Of the 34 patients, 24 patients received elective postoperative radiotherapy after total or subtotal resection(Group 1), and 10 patients received postoperative radiotherapy as a salvage treatment for recurrent tumors(Group 2). Ten patients received postoperative radiotherapy after total resection, and twenty-four after subtotal resection. Ten patients who had total tumor resection were referred for radiotherapy either because of angioblastic or malignant histologic type (4 patients in Group 1) or because of recurrent disease after initial surgery(6 patients in Group 2). Radiation dose of 50-56Gy was delivered over a period of 5-5.5 weeks using 4MV LINAC or Co-60 teletherapy unit. Results: Overall actuarial progression free survival (PFS) at 5 years was 80%. Survival was most likely affected by histologic subtypes. Five year PFS rate was 52% for benign angioblastic histology, as compared with 100% for classic benign histology. For malignant meningiomas, 5 year PFS rate was 44%. The recurrence rates of classic, angioblastic, and malignant type were 5%(1/21), 80%(4/5), and 50%(4/8), respectively. The duration between salvage post-operative radiotherapy and recurrence was longer than the duration between initial surgery and recurrence in the patients of group 2 with angioblastic or malignant histology. Conclusion: Postoperative radiotherapy of primary or recurrent intracranial meningiomas appears to be effective modality, especially in the patients with classic meningiomas. In angioblastic or malignant histologies, a more effective approach seems to be needed for decreasing recurrence rate

  19. Peripheral Sympathectomy for Raynaud's Phenomenon: A Salvage Procedure

    Full Text Available We retrospectively reviewed the effectiveness of peripheral sympathectomy for severe Raynaud's phenomenon. In this study, a total of 14 digits from six patients with chronic digital ischemic change were included. All patients had pain, ulcer, or gangrenous change in the affected digits and were unresponsive to pharmacologic or other nonsurgical therapies. In all cases, angiography showed multifocal arterial lesions, so microvascular reconstruction was unfeasible. Peripheral sympathectomy was performed as a salvage procedure to prevent digit amputation. The results were analyzed according to reduction of pain, healing of ulcers, and prevention of amputation. In 12 of the 14 digits, the ulcers healed and amputation was avoided. In the other two digits, the ulcers improved and progressive gangrene was limited. As a salvage procedure for Raynaud's phenomenon recalcitrant to conservative treatment, peripheral sympathectomy improves perfusion to ischemic digits and enables amputation to be avoided.

    Purpose/Objective: The precise role of salvage radiotherapy (RT) following chemotherapy (CT) failure in patients with Hodgkin's disease (HD) remains undefined. The aims of this study are: (1) to assess the pattern of failure, failure-free and overall survival, in patients who receive salvage RT for HD after CT failure; and (2) to identify patient subsets most suitable for this treatment approach. Materials and Methods: A review of patients treated between 1978 and 1992 at the Peter MacCallum Cancer Institute identified 52 patients with relapsed/refractory HD following CT who received RT with curative intent. Eligibility for this study required either biopsy confirmation of relapse/residual disease, or else clear clinical or radiological disease progression. Patient characteristics at diagnosis: median age 26, with 32% > 40 years old; M/ F 31/21; stage I-4, II-16, III-25, IV-7. Initial CT was MOPP- 31 patients, ABVD-1, both-16. A median 6 cycles of CT was given per regimen. Prior to salvage RT, 26/52 patients had received both MOPP and ABVD, either as sequential regimens, or as alternating or hybrid protocols. The response to initial CT was: CR-30, PR/SD-18, PD-4. Duration of initial CR was < 12 months in 8/30 patients. Salvage treatment consisted of radiotherapy to all known areas of disease. Doses ranged from 3600-4000 cGy. Results: Twenty three patients (45%) achieved CR. With a median follow-up of 70 months (range 4.8-166), actuarial median failure free survival (FFS) and overall survival (OS) are 22 months and 83 months respectively. Actuarial 5 year FFS and OS are 26% and 57% respectively. Patients with CR duration > 12 months following initial CT, only one CT regimen prior to salvage RT, and anatomically limited relapse had a significantly longer FFS. These factors, and age < 40 were associated with significantly longer OS. Only 6% of patients failed solely in the irradiated volume as first site of relapse, with the total in-field relapse of 30%.

    The most common surgical approach in case of local tumor recurrence after quadrantectomy and radiotherapy is salvage mastectomy. Breast reconstruction is the subsequent phase of the treatment and the plastic surgeon has to operate on previously irradiated and manipulated tissues. The medical literature highlights that breast reconstruction with tissue expanders is not a pursuable option, considering previous radiotherapy a contraindication. The purpose of this retrospective study is to evaluate the influence of previous radiotherapy on 2-stage breast reconstruction (tissue expander/implant). Only patients with analogous timing of radiation therapy and the same demolitive and reconstructive procedures were recruited. The results of this study prove that, after salvage mastectomy in previously irradiated patients, implant reconstruction is still possible. Further comparative studies are, of course, advisable to draw any conclusion on the possibility to perform implant reconstruction in previously irradiated patients.

    The publication focuses on the X-ray morphology of lungs. While one chapter is dedicated to the diagnoses obtained during the postoperative case of patients operated for the lungs a second chapter deals with the X-ray diagnosis of patients during the first days after lung surgery. Chapter 3 discusses the postoperative medical care of patients in medical intensive case units after operations other than lung surgery. The parallels between the critical care of patients after heart surgery and the critical care after operations other than heart surgery explain their simultaneous discussion in one chapter. Some diagnoses refer to patients subjected to long-term oxygen breathing and patients after abdomen and bone joint surgery. These are parallels between the volume 'Postoperative X-ray morphology: Blood vessels' and the chapter 'Heart' dealing with the coronary vessels; postoperative changes due to cogenital vitiae belong to pediatric radiology. The oesophagus dealt with in 'mediastinum und mediastinal organs' is also discussed in the volume on 'Postoperative X-ray morphology: Abdomen.' In order to avoid repetitions both chapters represent but a selection of facts. The publication focuses on the medical care of adult heat patients after cardiac valve surgery and coronary bypass surgery on the basis of native diagnostics. Methods of a more radical nature (for example those preceding re-operations) are only mentioned briefly. (orig./MG) [de

    Video Assisted Thoracoscopic Surgical (VATS) lobectomy is now considered feasible and safe. Nevertheless, thoracic surgeons need to be aware of dramatic complications that may occur during this procedure and how best to manage them. We report the case of a severe tear of the right pulmonary artery (PA) during elective VATS upper lobectomy, leading to emergency conversion to control the bleeding. Initial arterial repair was performed by end-to-end anastomosis. Early CT angiography showed thrombosis of the right PA due to anastomotic stenosis. We performed emergency pulmonary arterioplasty with a prosthetic patch to save the right lung. A CT scan days after surgical lung salvage confirmed the permeability of the PA and normal vascularization of the two remaining right lobes. We discuss herein this dramatic complication of VATS lobectomy, the viability of the lung after pulmonary arterial thrombosis, and advocate for early postoperative imaging after pulmonary arterioplasty.

    PurposeImplanted venous access devices (IVADs) are often used in patients who require long-term intravenous drug administration. The most common causes of device dysfunction include occlusion by fibrin sheath and/or catheter adherence to the vessel wall. We present percutaneous endovascular salvage techniques to restore function in occluded catheters. The aim of this study was to evaluate the feasibility, safety, and efficacy of these techniques.Methods and MaterialsThrough a femoral or brachial venous access, a snare is used to remove fibrin sheath around the IVAD catheter tip. If device dysfunction is caused by catheter adherences to the vessel wall, a new “mechanical adhesiolysis” maneuver was performed. IVAD salvage procedures performed between 2005 and 2013 were analyzed. Data included clinical background, catheter tip position, success rate, recurrence, and rate of complication.ResultsEighty-eight salvage procedures were performed in 80 patients, mostly women (52.5 %), with a mean age of 54 years. Only a minority (17.5 %) of evaluated catheters were located at an optimal position (i.e., cavoatrial junction ±1 cm). Mechanical adhesiolysis or other additional maneuvers were used in 21 cases (24 %). Overall technical success rate was 93.2 %. Malposition and/or vessel wall adherences were the main cause of technical failure. No complications were noted.ConclusionThese IVAD salvage techniques are safe and efficient. When a catheter is adherent to the vessel wall, mechanical adhesiolysis maneuvers allow catheter mobilization and a greater success rate with no additional risk. In patients who still require long-term use of their IVAD, these procedures can be performed safely to avoid catheter replacement

    Local failure rates following treatment for squamous cell carcinoma of the oral cavity have been reported to be in the range of 25%-48%. This study investigated the pattern of failure for squamous cell carcinoma (SCC) of the oral cavity and evaluated salvage surgery for local recurrent disease. The tumor files of 549 patients undergoing treatment for SCC of the oral cavity between 1980 and 2000 at Chiba Cancer Center Hospital were reviewed. Of 549 patients, 289 were initially treated with radiation therapy for their primary tumor, and 260 with surgery, either with or without radiation therapy. One hundred and sixty-one patients developed failures, yielding a failure rate of 29.3%. The site of recurrent tumor was local in 72 (13.1%) patients, regional in 89 (16.2%) patients, and distant in 5 (0.9%) patients. Local failure developed in 49 (17.0%) patients with radiation therapy and in 23 (8.8%) patients with surgery. Out of these 72 patients with local failure, 41 (56.9%) patients had salvage surgery for their disease. Twenty-five (73.5%) of the 34 patients initially treated with radiation therapy were salvaged with surgery, and 4 (57.1%) of the 7 patients initially treated with surgery were cured with further surgery. For the treatment of patients with local failure, the disease should be diagnosed more carefully than untreated disease. The disease that has recurred after radiation therapy may be more likely to be salvaged by surgery, however, the disease that has developed after surgery may have a limited indication for re-surgery.

    The management of retinoblastoma (RB) has dramatically changed over the past two decades. The introduction of chemotherapy has transformed treatment algorithms completely. Chemotherapy is currently used as a first line approach for children with RB and can be delivered by intravenous, intra-arterial and intravitreal routes. However, there still remains some controversy on the treatment of advanced RB, especially in eyeball salvage. This article described domestic and international approaches to eyeball salvage treatment. We would like to further discuss our opinion on the management of advanced RB based on our clinical experience for attracting more clinical concern on this issue. Many factors should be considered when choosing the appropriate conservative therapy. The choice of eyeball salvage treatment not only depends upon the tumor staging and laterality but also upon compliance and economic factors. Doctors and parents should not blindly pursue eye saving. However, there are still cases where enucleation is definitely the treatment of choice. (Chin J Ophthalmol, 2016, 52: 728-732) .

    Nicotinamide adenine dinucleotide (NAD + ) is an essential coenzyme for various physiological processes including energy metabolism, DNA repair, cell growth, and cell death. Many of these pathways are typically dysregulated in cancer cells, making NAD + an intriguing target for cancer therapeutics. NAD + is mainly synthesized by the NAD + salvage pathway in cancer cells, and not surprisingly, the pharmacological targeting of the NAD + salvage pathway causes cancer cell cytotoxicity in vitro and in vivo. Several studies have described the precise consequences of NAD + depletion on cancer biology, and have demonstrated that NAD+ depletion results in depletion of energy levels through lowered rates of glycolysis, reduced citric acid cycle activity, and decreased oxidative phosphorylation. Additionally, depletion of NAD + causes sensitization of cancer cells to oxidative damage by disruption of the anti-oxidant defense system, decreased cell proliferation, and initiation of cell death through manipulation of cell signaling pathways (e.g., SIRT1 and p53). Recently, studies have explored the effect of well-known cancer therapeutics in combination with pharmacological depletion of NAD + levels, and found in many cases a synergistic effect on cancer cell cytotoxicity. In this context, we will discuss the effects of NAD + salvage pathway inhibition on cancer cell biology and provide insight on this pathway as a novel anti-cancer therapeutic target.

    1993-02-01

    A total of 130 infrapopliteal in situ saphenous vein bypasses were performed in 128 patients between January 1980 and June 1991. The indication for surgery was critical ischaemia with impending limb loss in 121 patients; seven suffered from severe claudication. The distal anastomosis was to the popliteal artery below the knee in 60 cases (46.2%) and in 70 (53.8%) to the tibioperoneal arteries. The results, in terms of secondary patency and limb salvage rates, of the first 68 procedures (1980-1985) and subsequent 62 (1986-June 1991) were compared. In the first period, a secondary patency rate of 42.6% and a limb salvage rate of 67.0% were obtained, compared with 71.3 and 80.8% respectively in the second. These differences are significant for patency (P < 0.005) and limb salvage (P < 0.01). These results show that the in situ technique can give acceptable results but a learning period with a high percentage of early failures is to be expected.

    ) + PMMC flap reconstruction. Flaps survived in all cases, PCF developed in 2 cases (12.5%) with wound infection but healed conservatively within 2 weeks. Dropped shoulder occurred in 3 cases (18.75%) treated by physiotherapy. Mild postoperative chest infection developed in 7 cases (36.84%) improved by broad spectrum antibiotics and chest physiotherapy. Conclusion: Routine use of pectoralis major myocutaneous flap in salvage laryngeal surgery is of great help in such high risk patients to minimize incidence of pharyngocutaneous fistula and to allow primary skin wound healing. This flap will give the patient the advantage of early oral feeding, good tracheostomy care, short hospital stay and protection against catastrophic vascular blow out mortality.

    The choice of surgical approaches for salvage surgery based on the location and invasion of recurrent and residual lesions of nasopharyngeal carcinoma (NPC), surgical results, complications, and survival were assessed. Thirty-seven cases with recurrent and residual lesions of NPC underwent salvage surgery between March 1991 and January 2005 were analysed retrospectively. Of 37 patients, 23 were men and 14 women, with a median age of 46.5 years (26 - 57 years); 4 were at stage I, 10 at stage II, 14 at stage III, and 9 at stage IV; 5 cases were with cervical metastasis, including 3 cases of N1 and 2 cases N2. All recurrent and residual lesions of NPC were determined by biopsy. On the location and invasion of recurrent and residual lesions of NPC, 8 cases underwent endoscopic resection of lesions, 12 cases of the palate nasopharyngectomy, 5 cases of maxillary swing, 4 cases of maxillary swing plus prerenal approach, 2 cases of lateral rhinotomy plus coronal flap approach, and 6 cases transfacial plus nasal pyramid swing approach. Five cases with cervical metastasis received neck dissection in addition to the operations for recurrent and residual lesions of NPC. Postoperatively 31 cases received radiotherapy with dosage of 60 Gy, among them 15 cases with concurrent chemoradiation therapy, and 6 cases with clear surgical margin did not received radiotherapy or chemotherapy. The cases were followed up for 12 - 72 months, with a median of 45 months. Total resection for the recurrent and residual lesions of NPC accounted for 91.8% (34/37) and subtotal resection for 8.2% (3/37). The accident of perioperative complications was 24.3% (9/37). The 3- and 5-year overall disease-free survival rates (DFSR) were 62.1% and 43.3%, respectively. The 3- and 5-year overall survival rates (OSR) were 72.9% and 51.3%, respectively. The 5 year DFSR of cases at stage I-IV were 100%, 40%, 28% and 11% (χ(2) = 10.0, P < 0.01), respectively. The 5 year OSR were 100%, 70%, 35% and 28% (χ(2

    Nodal pelvic/retroperitoneal recurrent prostate cancer (PCa) after primary therapy can be treated with salvage lymph node dissection (salvage-LND) in order to delay disease progression and offer cure for a subset of patients. Whether adjuvant radiotherapy (ART) in affected regions improves the outcome by elimination of residual tumour burden remains unclear. A total of 93 patients with exclusively nodal PCa relapse underwent choline-positron-emission tomography-computed-tomography-directed pelvic/retroperitoneal salvage-LND; 46 patients had surgery only and 47 patients received ART in regions with proven lymph node metastases. In case of subsequent prostate specific antigen (PSA) progression, different imaging modalities were performed to confirm next relapse within or outside the treated region (TR). Mean follow-up was 3.2 years. Lymphatic tumour burden was balanced between the two groups. Additional ART resulted in delayed relapse within TR (5-year relapse-free rate 70.7 %) versus surgery only (5-year relapse-free rate 26.3 %, p < 0.0001). In both treatment arms, time to next relapse outside the TR was almost equal (median 27 months versus 29.6 months, p = 0.359). With respect to the detection of the first new lesion, regardless if present within or outside the TR, 5 years after the treatment 34.3 % of patients in the group with additional ART were free of relapse, versus 15.4 % in the surgery only group (p = 0.0122). ART had no influence on the extent of PSA reduction at latest follow-up compared to treatment with surgery only. ART after salvage-LND provides stable local control in TR and results in overall significant improved next-relapse-free survival, compared to patients who received surgery only in case of nodal PCa-relapse.

    Despite best efforts, postoperative complications such as postoperative respiratory failure may occur and prompt recognition of the process and management is required. Postoperative respiratory failure, such as postoperative pneumonia, postpneumonectomy pulmonary edema, acute respiratory distress-like syndromes, and pulmonary embolism, are associated with high morbidity and mortality. The causes of these complications are multifactorial and depend on preoperative, intraoperative, and postoperative factors, some of which are modifiable. The article identifies some of the risk factors, causes, and treatment strategies for successful management of the patient with postoperative respiratory failure. Copyright © 2015 Elsevier Inc.

    Full Text Available Background/Aim. Radical cystectomy is a method of choice in the therapy of infiltrative bladder cancer. The aim of this research was to analyze postoperative course after radical cystectomy (length of hospitalization, most frequent complications and utilization of antibiotics and transfusions. Methods. We analyzed the records of 82 patients operated on in the Department of Urology, Clinical Center of Vojvodina, in a three-year period. In order to aquire data World Health Organization (WHO has developed Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD methodology. Defined daily dose (DDD is the assumed average maintenance dose per day for a drug use for its main indication. Results. Continent urinary derivation was preformed in 23.15% cases. Postoperative complications occurred in 18.29% of patients. Average blood utilization was 2.19 units. Blood utilization for continent derivations (n = 48 was 4.6 units, and incontinent ones 3.36 units. Totally 159.33 DDD/100 bed days were used. Conclusion. When preforming continent derivation there is a significant increase in blood utilization. Frequency of postoperative complications correlates to those reported in the literature.

    Remote ischaemic preconditioning attenuates cardiac injury at elective surgery and angioplasty. We tested the hypothesis that remote ischaemic conditioning during evolving ST-elevation myocardial infarction, and done before primary percutaneous coronary intervention, increases myocardial salvage. 333 consecutive adult patients with a suspected first acute myocardial infarction were randomly assigned in a 1:1 ratio by computerised block randomisation to receive primary percutaneous coronary intervention with (n=166 patients) versus without (n=167) remote conditioning (intermittent arm ischaemia through four cycles of 5-min inflation and 5-min deflation of a blood-pressure cuff). Allocation was concealed with opaque sealed envelopes. Patients received remote conditioning during transport to hospital, and primary percutaneous coronary intervention in hospital. The primary endpoint was myocardial salvage index at 30 days after primary percutaneous coronary intervention, measured by myocardial perfusion imaging as the proportion of the area at risk salvaged by treatment; analysis was per protocol. This study is registered with ClinicalTrials.gov, number NCT00435266. 82 patients were excluded on arrival at hospital because they did not meet inclusion criteria, 32 were lost to follow-up, and 77 did not complete the follow-up with data for salvage index. Median salvage index was 0.75 (IQR 0.50-0.93, n=73) in the remote conditioning group versus 0.55 (0.35-0.88, n=69) in the control group, with median difference of 0.10 (95% CI 0.01-0.22; p=0.0333); mean salvage index was 0.69 (SD 0.27) versus 0.57 (0.26), with mean difference of 0.12 (95% CI 0.01-0.21; p=0.0333). Major adverse coronary events were death (n=3 per group), reinfarction (n=1 per group), and heart failure (n=3 per group). Remote ischaemic conditioning before hospital admission increases myocardial salvage, and has a favourable safety profile. Our findings merit a larger trial to establish the effect of remote

The results of the combined therapy in infiltrative urinary bladder cancer using transurethral resection and megavolt irradiation are demonstrated according to stage (T 2 , T 3 ) and histological grading (G 2 , G 3 ). The 5-years survival rate amounts around 80%, in deep infiltrating bladder cancer about 50%. The morbidity of postoperative megavolt therapy was negligible. The results are superior to megavolt therapy alone and approach the one achieved by radical surgery; in addition the possibility of salvage-cystectomy remains open. (Author)

    To evaluate the toxicity of therapeutic sequences High Intensity Focused Ultrasound (HIFU)-salvage radiotherapy (HIFU-RT) or radiotherapy-salvage HIFU (RT-HIFU) in case of locally recurrent prostate cancer. Nineteen patients had a local recurrence of prostate cancer. Among them, 10 patients were treated by HIFU-RT and 9 patients by RT- HIFU (4 by external beam radiotherapy [EBR] and 5 by brachytherapy [BRACHY]). Urinary side effects were assessed using CTCAE v4. At the time of the initial management, the median age was 66.5 years (53 72), the median PSA was 10.8 ng/mL (3.4 50) and the median initial Gleason score was 6.3 (5 8). Median follow-up after salvage treatment was 46.3 months (2 108). Thirty percent of the patients in the HIFU-RT group and 33.3 % of the patients in the RT-HIFU group, all belonging to the sub-group BRACHY-HIFU, had urinary complication greater than or equal to grade 2. Among all the patients, only 1 had grade 1 gastrointestinal toxicity. BRACHY-HIFU sequence seems to be purveyor of many significant urinary side effects. A larger database is needed to confirm this conclusion. (authors)

    Aim: To examine the usage and value of computed tomography (CT) following simultaneous pancreas and kidney (SPK) transplantation. Materials and methods: Indications for postoperative CT, key findings, and their influence on management were determined by retrospective analysis. Results: Ninety-eight patients underwent 313 CT examinations. Common indications for the examinations included suspected intra-abdominal collection (31.1%) and elevated serum amylase/lipase (24.1%). CT findings most frequently showed non-specific mild inflammation (27.6%), a normal scan (17.1%) and fluid collections (16.3%). High capillary blood glucose (CBG) was associated with resultant CT demonstration of graft vascular abnormalities, but otherwise, particular clinical indications were not associated with specific CT findings. Conclusion: Clinical findings in patients with SPK transplants are non-specific. The pattern of abnormalities encountered is significantly different to those seen in native pancreatic disease and demands a tailored protocol. CT enables accurate depiction of vascular abnormalities and fluid collections, thus reducing the number of surgical interventions that might otherwise be required. Elevated CBG should prompt urgent CT to exclude potentially reversible vascular complications. - Highlights: • The value of CT following simultaneous pancreas and kidney transplantation was assessed. • 313 CT scans were performed on 98 patients between January 2005 and August 2010. • Elevated blood glucose was associated with CT findings of graft vascular anomalities. • CT was particularly useful in directing operative versus non-operative intervention.

    Full Text Available The Heart Institute of the University of São Paulo, Medical School is a referral center for the treatment of congenital heart diseases of neonates and infants. In the recent years, the excellent surgical results obtained in our institution may be in part due to modern anesthetic care and to postoperative care based on well-structured protocols. The purpose of this article is to review unique aspects of neonate cardiovascular physiology, the impact of extracorporeal circulation on postoperative evolution, and the prescription for pharmacological support of acute cardiac dysfunction based on our cardiac unit protocols. The main causes of low cardiac output after surgical correction of heart congenital disease are reviewed, and methods of treatment and support are proposed as derived from the relevant literature and our protocols.

    To determine the haematological and microbiological characteristics of blood recovered by using a cell saver with a rigid centrifuge bowl (100ml) in paediatric scoliosis surgery and to determine whether it conforms to the standard expected in adult patients. A cross-sectional, descriptive cohort study was performed on 24 consecutive red blood cell (RBC) units recovered from the surgical field and processed by a Haemolite® 2+ (Haemonetics Corp., Braintree, MA, EE. UU.) cell saver. Data were collected regarding age, weight, surgical approach (anterior or posterior), processed shed volume and volume of autologous RBC recovered, full blood count, and blood culture obtained from the RBC concentrate, and incidence of fever after reinfusion. The processed shed volume was very low (939±569ml) with high variability (coefficient of variation=0.6), unlike the recovered volume 129±50ml (coefficient of variation=0.38). A statistically significant correlation between the processed shed volume and recovered RBC concentrate haematocrit was found (Pearson, r=.659, P=.001). Haematological parameters in the recovered concentrate were: Hb 11±5.3g dl(-1); haematocrit: 32.1±15.4% (lower than expected); white cells 5.34±4.22×103 ul(-)1; platelets 37.88±23.5×103 ul(-1) (mean±SD). Blood culture was positive in the RBC concentrate recovered in 13 cases (54.2%) in which Staphylococcus coagulase (-) was isolated. Cell salvage machines with rigid centrifuge bowls (including paediatric small volume) do not obtain the expected haematocrit if low volumes are processed, and therefore they are not the best choice in paediatric surgery.

    Full Text Available Introduction: Revision arthroplasty of the hip is becoming increasingly important in recent years. Early primary arthroplasty and longer life expectancy of the patients increases the number of revision surgery. Revision surgery of hip arthroplasty is major surgery for the patients, especially the elderly, with significant risks concerning the general condition of the patient. The aim of this work is to evaluate the outcome of bipolar hip arthroplasty as a salvage procedure for treatment of loosening of the acetabular cup with significant acetabular bone defects after total hip replacement (THR in multi-morbid patients.Patients and methods: During the period from January 1 2007 to December 31 2011 19 revision hip surgeries were performed in , in which the loosened acetabular cup was replaced by a bipolar head. The examined patient group consisted exclusively of female patients with an average of 75 years. The predominant diagnosis was “aseptic loosening” (84.2%. All patients in our study were multi-morbid. We decided to resort to bipolar hip arthroplasty due to the compromised general condition of patients and the major acetabular bone defects, which were confirmed intraoperatively. The postoperative follow-up ranged from 0.5 to 67 months (average 19.1 months. Results: Evaluation of the modified Harris Hip Score showed an overall improvement of the function of the hip joint after surgery of approximately 45%.Surgery was less time consuming and thus adequate for patients with significantly poor general health condition. We noticed different complications in a significant amount of patients (68.4%. The most common complication encountered was the proximal migration of the bipolar head.The rate of revision following the use of bipolar hip arthroplasty in revision surgery of the hip in our patients was high (21%. Despite the high number of complications reported in our study, we have noticed significant improvement of hip joint function as well

    This paper described the operations that took place during an oil spill that occurred in December 2007 when the Grande-Baie tugboat sank at the wharf in Port Alfred, in the Ha-Ha Bay on the Saguenay River, Quebec. Approximately 100 tonnes of diesel fuel was onboard the tug. Although the exact amount of diesel spilled during this event is not known, it is assumed that half of the ship's load in diesel was spilled into the ice-infested waters. Poor weather, the presence of pack ice and tides of 2.5 meters were present at the time. Two Canadian Coast Guard officers, one emergency officer from Environment Quebec and one from Environment Canada were called for response purposes, particularly to avoid spreading of the diesel fuel and to ensure that the oily water was recovered from inside the vessel during salvage operations. One of the key objectives was to prevent diesel spills by capping vessel vents, which proved to be very challenging. Oily water was pumped from inside the boat directly in the bay of the Saguenay River to facilitate salvage of the ship. This was the first time that this method was used in Canada, and was successful because of proper risk assessment. Many conditions were followed for the purpose of environmental protection, such as confinement, good observations by divers, agreed upon criteria to stop pumping, and adequate monitoring the the Regional Environmental Emergency Team (REET). The salvage operation lasted 19 days. The challenges associated with the migration and recovery of oil in icy waters were discussed along with the environmental issues associated with the spill, particularly with the imminent opening of the ice fishing season. 2 refs., 2 tabs.,5 figs.

  5. Synthesizing and salvaging NAD: lessons learned from Chlamydomonas reinhardtii.

    Full Text Available The essential coenzyme nicotinamide adenine dinucleotide (NAD+ plays important roles in metabolic reactions and cell regulation in all organisms. Bacteria, fungi, plants, and animals use different pathways to synthesize NAD+. Our molecular and genetic data demonstrate that in the unicellular green alga Chlamydomonas NAD+ is synthesized from aspartate (de novo synthesis, as in plants, or nicotinamide, as in mammals (salvage synthesis. The de novo pathway requires five different enzymes: L-aspartate oxidase (ASO, quinolinate synthetase (QS, quinolate phosphoribosyltransferase (QPT, nicotinate/nicotinamide mononucleotide adenylyltransferase (NMNAT, and NAD+ synthetase (NS. Sequence similarity searches, gene isolation and sequencing of mutant loci indicate that mutations in each enzyme result in a nicotinamide-requiring mutant phenotype in the previously isolated nic mutants. We rescued the mutant phenotype by the introduction of BAC DNA (nic2-1 and nic13-1 or plasmids with cloned genes (nic1-1 and nic15-1 into the mutants. NMNAT, which is also in the de novo pathway, and nicotinamide phosphoribosyltransferase (NAMPT constitute the nicotinamide-dependent salvage pathway. A mutation in NAMPT (npt1-1 has no obvious growth defect and is not nicotinamide-dependent. However, double mutant strains with the npt1-1 mutation and any of the nic mutations are inviable. When the de novo pathway is inactive, the salvage pathway is essential to Chlamydomonas for the synthesis of NAD+. A homolog of the human SIRT6-like gene, SRT2, is upregulated in the NS mutant, which shows a longer vegetative life span than wild-type cells. Our results suggest that Chlamydomonas is an excellent model system to study NAD+ metabolism and cell longevity.

    Autologous blood transfusion (ABT) drainage system is a new unwashed salvaged blood retransfusion system for total knee replacement (TKA). However, whether to use ABT drainage, closed-suction (CS) drainage or no drainage in TKA surgery remains controversial. This is the first meta-analysis to assess the clinical efficiency, safety and potential advantages regarding the use of ABT drains compared with closed-suction/no drainage. PubMed, Embase, and the Cochrane Library were comprehensively searched in March 2015. Fifteen randomized controlled trials (RCTs) were identified and pooled for statistical analysis. The primary outcome evaluated was homologous blood transfusion rate. The secondary outcomes were post-operative haemoglobin on days 3-5, length of hospital stay and wound infections after TKA surgery. The pooled data included 1,721 patients and showed that patients in the ABT drainage group might benefit from lower blood transfusion rates (16.59 % and 37.47 %, OR: 0.28 [0.14, 0.55]; 13.05 % and 16.91 %, OR: 0.73 [0.47,1.13], respectively). Autologous blood transfusion drainage and closed-suction drainage/no drainage have similar clinical efficacy and safety with regard to post-operative haemoglobin on days 3-5, length of hospital stay and wound infections. Autologous blood transfusion drainage offers a safe and efficient alternative to CS/no drainage with a lower blood transfusion rate. Future large-volume high-quality RCTs with extensive follow-up will affirm and update this system review.

    Conversion disorder is a psychiatric disorder in which psychological stress causes neurologic deficits. A 28-year-old female surgical patient had uneventful general anesthesia and emergence but developed conversion disorder 1 hour postoperatively. She reported difficulty speaking, right-hand numbness and weakness, and right-leg paralysis. Neurologic examination and imaging revealed no neuronal damage, herniation, hemorrhage, or stroke. The patient mentioned failing examinations the day before surgery and discontinuing her prescribed antidepressant medication, leading us to diagnose conversion disorder, with eventual confirmation by neuroimaging and follow-up examinations.

    Ascending and aortic arch surgery is associated with higher levels of blood loss and subsequent need for allogeneic blood transfusions. We hypothesized that aggressive, comprehensive blood conservation strategies may limit the need for transfusions and, subsequently, improve postoperative outcomes. Over a five-year period, 189 patients underwent proximal aortic surgery at our institution. Fifty-one patients underwent surgery using a comprehensive blood conservation strategy (BCS), including preoperative hemoglobin optimization, antifibrinolytic therapy, intraoperative acute normovolemic hemodilution, cell salvage and meticulous surgical technique. The remaining 138 patients underwent surgery using conventional techniques (CONV). Patients in the BCS group required fewer transfusions during their hospital stay compared to the conventional group (56.9% vs. 72.5%, p=0.041). When examining elective cases, this trend widens, with 40.0% of BCS patients requiring any transfusions compared to 72.9% patients in the conventional group (p=0.001). Red cell (47.1% vs. 62.3%, p=0.06), plasma (43.1% vs. 61.6%, p=0.02) and platelets (27.5% vs. 47.8%, p=0.01) were also less frequently required in the BCS group than the conventional group, respectively. When a transfusion was required, patients in the BCS group received significantly fewer units of red blood cells (2.8 ± 7.0 units) than the conventional group (5.81 ± 9.5 units; p=0.039). Mortality was similar in both groups (BCS 7.8%, conventional 10.9%, p=0.54); however, there was significantly less morbidity in the BCS group, using a composite of any of 10 major postoperative complications (23.5% vs. 39.1%; p=0.046). Median intensive care unit (ICU) and hospital lengths of stay were 2 and 7 days in the BCS group and 2 and 8 days in the CONV group (p=0.15), respectively. The aggressive use of a comprehensive blood conservation strategy in ascending and aortic arch surgery can significantly reduce the need for blood transfusions

    The relationship between residual urine output and postoperative survival in maintenance hemodialysis patients is unknown. To explore the relationship between amount of urine before surgery and postoperative mortality and differences between postoperative nonanuria and anuria in maintenance hemodialysis patients. A total of 109 maintenance hemodialysis patients underwent major operations. Anuria was defined as urine output <30 mL in the 8 hours before the first session of postoperative dialysis. Propensity scores for postoperative anuria were developed. Postoperative residual urine output was 159.2 mL/8 h (SD, 115.1) in 33 patients; 76 patients were anuric. Preoperative residual urine output and adequate perioperative blood transfusion were positively related to postoperative urine output. Propensity-adjusted 30-day mortality was associated with postoperative anuria (odds ratio [OR], 4.56; 95% confidence interval [CI], 1.16-17.96; P = .03), prior stroke (OR, 4.46; 95% CI, 1.43-13.89; P = .01) and higher disease severity (OR, 1.10; 95% CI, 1.00-1.21; P = .049) at the first postoperative dialysis. OR of 30-day mortality was 5.38 for nonanuria to anuria vs nonanuria to nonanuria (P = .03) and 5.13 for preoperative anuria vs nonanuria to nonanuria (P = .01). By Kaplan-Meier analysis, 30-day mortality differed significantly among patients for nonanuria to nonanuria, anuria, and nonanuria to anuria (log rank, P = .045). Patients with preoperative nonanuria and postoperative anuria had higher mortality than did patients with no anuria before and after surgery and patients with anuria before surgery. Postoperative residual urine output is an important surrogate marker for disease severity.

    Full text: Imaging assessment of brain tumors following surgery is complex and depends upon several factors, including the location of the tumor, the surgical procedure and the disease process for which it was performed. Depending upon these factors, one or a combination of complementary imaging modalities may be required to demonstrate any clinically relevant situation, to assist the surgeon in deciding if repeat surgery is necessary. Conventional magnetic resonance imaging (MRI) can show the shape, size, signal intensity, and enhancement of a brain tumor. It has been widely used to diagnose and differentiate brain tumors and to assess the surgery outcomes. Longitudinal MRI scans have also been applied for the assessment of treatment and response to surgery. The newly developed MRI techniques, including diffusion weighted imaging (DWI), perfusion weighted imaging (PWI) and magnetic resonance spectroscopy (MRS), have the potential to provide the molecular, functional and metabolic information of preoperative and postoperative brain tumors. Postoperative diffusion and perfusion magnetic resonance imaging are especially useful in predicting early functional recovery from new deficits after brain tumor surgery.This lecture will stress the principles, applications, and pitfalls of conventional as well as newly developing functional imaging techniques following operation of brain tumors

    To determine whether post-radiotherapy (RT) biopsy (PRB) adequately predicts the presence, location, and histological features of cancer in the salvage radical prostatectomy (SRP) specimen. Before salvage treatment, a PRB is required to confirm the presence of locally recurrent or persistent cancer and to determine the extent and location of the prostate cancer. SRP was performed between 1998 and 2011 on 198 patients. All patients underwent a PRB. PRB and SRP specimens were evaluated by a genitourinary pathologist. Patients had external-beam RT alone (EBRT; 71%) or brachytherapy with or without EBRT (29%). Of the men undergoing SRP, 26 (14%) were clinical stage ≥T3, with 13% of PRBs with Gleason score ≥8. Cancer was unilateral in 120 (61%) biopsies, with contralateral or bilateral prostate cancer at SRP in 49%. In the SRP specimen, cancer was multifocal in 57%. Cancer was upgraded at SRP in 58% of men, with 20% having an increase in primary Gleason grade. The accuracy of PRB varied by region from 62% to 76%, with undetected cancers ranging from 12% to 26% and most likely to occur at the mid-gland. Radiation-recurrent prostate cancers were often multifocal, and biopsy missed up to 20% of tumours. More than half of the cancers were upgraded at SRP, and many that were unilateral on PRB were bilateral at SRP. © 2013 BJU International.

    Olaf Zagólski

    Full Text Available ABSTRACT INTRODUCTION: Intense pain is one of the most important postoperative complaints after tonsillectomy. It is often described by patients as comparable to the pain that accompanies an acute tonsillitis. Although recurrent tonsillitis is the most frequent indication for surgery, many tonsillectomies are performed due to other indications and these patients may be unfamiliar with such pain. OBJECTIVE: To verify whether individuals with recurrent tonsillitis experience different post-tonsillectomy pain intensity than those with other indications for surgery, with no history of episodes of acute tonsillitis. METHODS: A total of 61 tonsillectomies were performed under general anesthesia, using a potassium titanyl phosphate (KTP laser (to eliminate the potential influence on the study results of forceful dissection of fibrotic tonsils in patients with history of recurrent tonsillitis and multiple ligations of blood vessels within the tonsillar beds. The patients received 37.5 mg Tramadoli hydrochloridum + 325 mg Paracetamol tablets for 10 days. Postoperative variables included the duration of hospital stay, postoperative hemorrhage and readmission rate. The patients reported pain intensity on consecutive days, pain duration, weight loss on postoperative day 10, character, intensity and duration of swallowing difficulties, and the need for additional doses of painkillers. Healing was also assessed. Capsular nerve fibers were histologically examined in the resected tonsils by immunostainings for general and sensory markers. RESULTS: Indications for the surgery were: recurrent acute tonsillitis (34 patients, no history of recurrent tonsillitis: focus tonsil (20 and intense malodour (7. Pain intensity on postoperative days 3-4 and incidence of readmissions due to dehydration were significantly higher in the group with no history of recurrent tonsillitis.

    Indications for the use of nuclear medicine techniques, mostly bone scintigraphy, occur in case of diagnostic problems, especially if there are discrepancies between the clinical symptoms and X-ray findings. This may happen in case of stress fractures, fractures in bones difficult to judge by X-ray imaging, and in the differentation of recent versus old fracture. A further indication for bone scanning is to assess the extent of skeletal lesions in polytrauma and in the battered child syndrome. In postoperative patients bone scanning is most frequently performed in order to assess loosening or infection of endoprosthesis. Due to bone remodelling uptake of Tc-diphosphonates varies between cemented and cementfree implants. This fact should be taken into consideration when interpreting bone scans in areas with endoprostheses. In both trauma and postoperative patients, indications for nuclear medicine imaging exist if healing is complicated. Bone scanning can be used to assess pseudoartrosis or non-union, infection, viability of grafts and bone fragments and reflex sympathetic dystrophy. In suspicious infection with positive bone scan, white blood cell or microcollid scintigraphy can be used for further differentiation.

    Intravenous thrombolysis (IVT) is beneficial in reducing disability in selected patients with acute ischemic stroke. There are numerous contraindications to IVT. One is recent surgery. The aim of this study was to analyze the safety of IVT in patients with postoperative stroke. Data of consecutive IVT patients from the Telemedical Project for Integrative Stroke Care thrombolysis registry (February 2003 to October 2014; n=4848) were retrospectively searched for keywords indicating preceding surgery. Patients were included if surgery was performed within the last 90 days before stroke. The primary outcome was defined as surgical site hemorrhage. Subgroups with major/minor surgery and recent/nonrecent surgery (within 10 days before IVT) were analyzed separately. One hundred thirty-four patients underwent surgical intervention before IVT. Surgery had been performed recently (days 1-10) in 49 (37%) and nonrecently (days 11-90) in 85 patients (63%). In 86 patients (64%), surgery was classified as major, and in 48 (36%) as minor. Nine patients (7%) developed surgical site hemorrhage after IVT, of whom 4 (3%) were serious, but none was fatal. One fatal bleeding occurred remotely from surgical area. Rate of surgical site hemorrhage was significantly higher in recent than in nonrecent surgery (14.3% versus 2.4%, respectively, odds ratio adjusted 10.73; 95% confidence interval, 1.88-61.27). Difference between patients with major and minor surgeries was less distinct (8.1% and 4.2%, respectively; odds ratio adjusted 4.03; 95% confidence interval, 0.65-25.04). Overall in-hospital mortality was 8.2%. Intracranial hemorrhage occurred in 9.7% and was asymptomatic in all cases. IVT may be administered safely in postoperative patients as off-label use after appropriate risk-benefit assessment. However, bleeding risk in surgical area should be taken into account particularly in patients who have undergone surgery shortly before stroke onset. © 2017 American Heart Association, Inc.

    The genome of T4-type Vibrio bacteriophage KVP40 has five genes predicted to encode proteins of pyridine nucleotide metabolism, of which two, nadV and natV , would suffice for an NAD + salvage pathway. NadV is an apparent nicotinamide phosphoribosyltransferase (NAmPRTase), and NatV is an apparent bifunctional nicotinamide mononucleotide adenylyltransferase (NMNATase) and nicotinamide-adenine dinucleotide pyrophosphatase (Nudix hydrolase). Genes encoding the predicted salvage pathway were cloned and expressed in Escherichia coli , the proteins were purified, and their enzymatic properties were examined. KVP40 NadV NAmPRTase is active in vitro , and a clone complements a Salmonella mutant defective in both the bacterial de novo and salvage pathways. Similar to other NAmPRTases, the KVP40 enzyme displayed ATPase activity indicative of energy coupling in the reaction mechanism. The NatV NMNATase activity was measured in a coupled reaction system demonstrating NAD + biosynthesis from nicotinamide, phosphoribosyl pyrophosphate, and ATP. The NatV Nudix hydrolase domain was also shown to be active, with preferred substrates of ADP-ribose, NAD + , and NADH. Expression analysis using reverse transcription-quantitative PCR (qRT-PCR) and enzyme assays of infected Vibrio parahaemolyticus cells demonstrated nadV and natV transcription during the early and delayed-early periods of infection when other KVP40 genes of nucleotide precursor metabolism are expressed. The distribution and phylogeny of NadV and NatV proteins among several large double-stranded DNA (dsDNA) myophages, and also those from some very large siphophages, suggest broad relevance of pyridine nucleotide scavenging in virus-infected cells. NAD + biosynthesis presents another important metabolic resource control point by large, rapidly replicating dsDNA bacteriophages. IMPORTANCE T4-type bacteriophages enhance DNA precursor synthesis through reductive reactions that use NADH/NADPH as the electron donor and NAD

    Purpose: To evaluate the results of salvage radiotherapy (RT) after inadequate surgery in patients with invasive carcinoma of the cervix. Methods and Materials: Between 1996 and 2001, 105 invasive cervical carcinoma patients were treated at our center with external beam RT with or without intracavitary RT after having undergone total/subtotal hysterectomy at outside institutions. Results: The median follow-up was 34 months. The gap between surgery and RT was 23-198 days (median, 80). Clinically visible residual disease was present in 81 patients (77.1%). Total hysterectomy had been done in 82 patients (78%) and subtotal hysterectomy in 23 patients (22%). The 5-year overall survival, disease-free survival, and pelvic control rates of all patients were 55.2%, 53.3%, and 72.4%, respectively. On univariate analysis, older age, total hysterectomy, hemoglobin level >10 g% before RT, nonsquamous histologic type, use of intracavitary RT, a shorter gap between surgery and RT, and the absence of, or a small volume of, residual disease favorably affected the outcome. The 5-year actuarial rate of late toxicity (Radiation Therapy Oncology Group Criteria) was 19% in the rectum, 4.8% in the bladder, 24.8% in the skin, and 14.3% in the small intestine. Conclusions: Inadequate and inappropriate surgery in invasive cervical cancer with resulting gross residual disease is common in India. Factors such as the use of intracavitary RT, the correction of anemia, and a shorter gap between surgery and RT will enable postoperative RT to achieve acceptable results with minimal morbidity

    Breast reconstruction with implants is a real challenge in patients with large breast volume. Skin-reducing inverted-T mastectomy is the best solution for these patients. Delayed wound healing or necrosis at the T-junction area can be seen in this procedure, although it may also lead to severe conditions such as the exposure and loss of implant. In this article, the use of local pedicled flap for the management of these situations was discussed. Between April 2010 and July 2015, 54 patients underwent breast reconstruction by inverted-T skin-reducing mastectomy and immediate implant-based breast reconstruction at our clinic. During the postoperative follow-up period, necrosis at the T-junction area was observed in 8 patients. All the patients received proper wound care, and the necrosis was surgically debrided. The defect was closed with Limberg-like rectangular flap. The mean age was 45.2 (range, 33-54) years. The mean body mass index was 25.57 ± 6.53 (range, 21.2-35.2) kg/m. The mean follow-up was 10.9 (range, 4-19) months. Two patients had implant exposure at the defect site after the debridement. There was no implant loss in any of the patients. The Limberg-like rectangular flap can be used as a salvage option in complicated skin-reducing mastectomies and can be considered as a safe and effective method because of its easy-to-use nature, low cost, and no need for microsurgery experience.

    Descriptive cross-sectional survey study. Limb salvage spares an extremity at risk for amputation after a major traumatic injury. Psychosocial recovery for individuals with lower extremity limb salvage has been discussed in the literature. However, to date, psychosocial reactions for individuals with upper extremity (UE) limb salvage have not been examined. To determine which factors may influence psychosocial adaptation to UE limb salvage. Participants (n = 30; 28 males) were adults (mean, 30.13; range, 18-61) who sustained an UE limb salvage from a traumatic event. Adaptation was measured using a modified version of the Reactions to Impairment and Disability Inventory. A linear mixed-effects regression found that worse psychosocial adaptation was associated with having less than a college degree, being less than 6 months post-injury, being older than 23 years, and having more pain. Dominant hand injuries were found to influence poor adaptation on the denial Reactions to Impairment and Disability Inventory subscale only. The results of this study indicate that there is potential for nonadaptive reactions and psychological distress with certain variables in UE limb salvage. Therapists may use these results to anticipate which clients may be at risk for poor psychosocial outcomes. This study indicates the need for early consideration to factors that affect psychological prognosis for the UE limb salvage population. However, future research is indicated to better understand the unique psychosocial challenges and needs of these individuals. 4. Copyright © 2017 Hanley & Belfus. Published by Elsevier Inc.

    2010-06-01

    Adequate mitochondrial DNA (mtDNA) copies are required for normal mitochondria function and reductions in mtDNA copy number due to genetic alterations cause tissue-specific mtDNA depletion syndrome (MDS). There are eight nuclear genes, directly or indirectly involved in mtDNA replication and mtDNA precursor synthesis, which have been identified as the cause of MDS. However, the tissue specific pathology of these nuclear gene mutations is not well understood. Here, mtDNA synthesis, mtDNA copy number control, and mtDNA turnover, as well as the synthesis of mtDNA precursors in relation to the levels of salvage enzymes are discussed. The question why MDS caused by TK2 and p53R2 mutations are predominantly muscle specific while dGK deficiency affected mainly liver will be addressed.

    Full Text Available During the past decade, overall results of treatment of multiple myeloma (MM have been improved and survival curves are now significantly better with respect to those obtained with historical treatment. These improvements are linked to a deeper knowledge of the biology of disease and to the introduction in clinical practice of drugs with different mechanism of action such as proteasome inhibitors and immunomodulatory drugs (IMiDs. However, MM remains in most cases an incurable disease. For patients who relapse after treatment with novel agents, the prognosis is dismal and new drugs and therapeutic strategies are required for continued disease control. In this review, we summarize new insights in salvage therapy for relapsed/refractory MM as emerging from recent clinical trials exploring the activity of bendamustine, new generation proteasome inhibitors, novel IMiDs, monoclonal antibodies, and drugs interfering with growth pathways.

    Objective To determine the value of apparent diffusion coefficient (ADC) histogram parameters for the prediction of individual survival in patients undergoing surgery for recurrent glioblastoma (GBM) in a retrospective cohort study. Methods Thirty-one patients who underwent surgery for first recurrence of a known GBM between 2008 and 2012 were included. The following parameters were collected: age, sex, enhancing tumor size, mean ADC, median ADC, ADC skewness, ADC kurtosis and fifth percentile of the ADC histogram, initial progression free survival (PFS), extent of second resection and further adjuvant treatment. The association of these parameters with survival and PFS after second surgery was analyzed using log-rank test and Cox regression. Results Using log-rank test, ADC histogram skewness of the enhancing tumor was significantly associated with both survival (p = 0.001) and PFS after second surgery (p = 0.005). Further parameters associated with prolonged survival after second surgery were: gross total resection at second surgery (p = 0.026), tumor size (0.040) and third surgery (p = 0.003). In the multivariate Cox analysis, ADC histogram skewness was shown to be an independent prognostic factor for survival after second surgery. Conclusion ADC histogram skewness of the enhancing lesion, enhancing lesion size, third surgery, as well as gross total resection have been shown to be associated with survival following the second surgery. ADC histogram skewness was an independent prognostic factor for survival in the multivariate analysis.

    There are still few comparison reports regarding the safety of salvage surgery for recurrence and persistence following platinum-based chemoradiotherapy (CRT) and cetuximab-based bioradiotherapy (BRT), which are frequently used as non-surgical therapies for advanced head and neck carcinomas. This study compared the safety of salvage surgery following CRT against that following BRT for advanced hypopharyngeal cancer. The study examined 34 cases who underwent salvage surgery following CRT and 7 cases who underwent salvage surgery following BRT from September 2002 to December 2015. The number of cases that were able to undergo salvage surgery was 34 among 67 recurrence and persistence cases following CRT and 7 of 8 cases following BRT. In terms of the surgical procedure, salvage neck dissection was conducted for 22 cases in the CRT group and 5 cases in the BRT group, with no significant differences observed between both including the surgical time and amount of bleeding, and with no major complications in either group. Total hypopharynx or total laryngectomy resection for salvage was conducted for 19 cases in the CRT group and 3 cases in the BRT group, upon which we observed anastomotic leakage in 3 cases in the CRT group and 1 case in the BRT group; however, there was no significant difference in the onset frequency. There was no clear difference regarding safety between salvage surgery following CRT and following BRT for locally advanced hypopharyngeal cancer. However, regarding the adaptation of salvage surgery, the possibility of limitations in the CRT group was suggested in comparison with the BRT group. (author)

    patient follow-up was 21.2 months (IQR, 7.9-36.8). Before CPIAT, all patients required a mean of 120.8 morphine equivalent milligrams per day (MEQ/d), which improved to 48.5 MEQ (P < .001 compared with preoperative requirements) at most recent follow-up. Of these patients, 44% (n = 28) achieved narcotic independence. All patients were able to achieve stable glycemic control with a mean insulin requirement of 16 units per day. Of these patients, 20% (n = 13) were insulin independent after CPIAT. Mean postoperative glycosylated hemoglobin was 7.8% (range, 4.6-12.5). Islet cell viability was confirmed with endocrine testing and mean C-peptide levels 6 months after CPIAT were 0.91 ng/mL (range, 0.1-3.0). The SF-36 QOL survey administered postoperatively demonstrated improvement in all tested modules. This study is the first to examine the results of salvage therapy with CPIAT for patients with refractory chronic pancreatitis. Patients undergoing CPIAT achieved improved postoperative narcotic requirements, stable glycemic control, and improved QOL. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Animal bites are fairly rare events but can cause devastating traumatic injuries to the victim. In addition to the soft tissue, vascular, and orthopedic trauma inflicted by these occurrences, bite injuries also have the potential to introduce an inoculum of microbes, which may progress to an infection if not treated properly and expeditiously.We present the case of a healthy male who sustained multiple bite wounds from a domestic zebra to his left upper extremity. This attack caused severe damage, including devascularization of the arm at the brachial artery, disruption of the distal biceps and brachialis, stripping of the forearm nerves, and shearing of the overlying soft tissue. The patient was taken emergently to the operating room for revascularization of the extremity utilizing a vein bypass graft. The soft tissue injuries were addressed with numerous irrigation and debridement procedures, during which coverage of the vein bypass graft was obtained using a variety of techniques, including skin flaps, musculocutaneous advancements, and the application of an acellular dermal matrix (AlloDerm and a collagen-glycosaminoglycan matrix (Integra.Wound cultures obtained intra-operatively during the irrigation and debridement procedures were notable for the growth of multiple microbes, including Rhodococcus spp., which have been documented to cause infection in immunocompromised patients. The patient in this case was treated with a prolonged course of antibiotics, and wound cultures negative for microbial growth were eventually obtained prior to final closure of his wound. The patient then underwent successful biceps reconstruction with a pedicled latissimus dorsi muscle transfer. This case documents the extraordinary multidisciplinary approach provided in the salvage, management, and eventual reconstruction of a mangled left upper extremity that had sustained devastating traumatic injuries resulting from a rather unusual source.

    The aim of this study was to present the outcome of patients treated with salvage cryotherapy after radiotherapy for prostate cancer at one institution. Consecutive patients treated between 2007 and 2013 with transperineal cryotherapy for biopsy-verified local recurrence after radiotherapy were investigated. An external reviewer retrieved outcome data retrospectively from medical records. Complications were graded according to the Clavien classification. One patient with less than 1 year of follow-up was excluded from the analysis of side-effects. Thirty patients were included, 29 of whom had a follow-up of at least 1 year. The median follow-up was 2.7 years (range 1-6.5 years). Eleven of the 23 patients without hormonal treatment at the time of cryotherapy reached a prostate-specific antigen (PSA) nadir of less than 0.5 ng/ml. At the end of follow-up five of these 23 patients still had a PSA below 0.5 ng/ml and 10 were free from recurrence according to the Phoenix definition. Clinical recurrence (verified with imaging or biopsies) was detected in 13 patients, six of which were local. One patient died from prostate cancer. Eleven patients had urinary incontinence grade 1-2 and three had grade 3-4, seven had pelvic pain, three had severe but transitory tissue sloughing, three developed a urethral stricture or had prolonged urinary retention, and one developed a urinary fistula 4.5 years after cryotherapy. Salvage cryotherapy should be considered as an alternative to hormonal treatment and surgery for local recurrence after radiotherapy for prostate cancer. The results compare well to those reported from centres with longer experience.

    The failed back surgery syndrome (FBSS) is one of the most perplexing medical and medicoeconomic problems facing our health system today. In many studies reoperation rates tend to be between 10 and 20%, but as many as 20-45% 3 of patients may have persistent back or radicular pain following what was to have been definitive therapy. The causes for the FBSS are very complex. The Workmen's Compensation system and medicolegal trends toward very high settlements of litigation for injury have provided serious incentive for patients to remain symptomatic. It is difficult to analyze any statistical survey of symptomatic back patients without serious bias from this group of patients. Others suggest that patients with severe psychological problems, drug abuse, and alcoholism are inappropriately selected as surgical candidates. They believe that careful psychological evaluation of patients minimizes FBSS. Even if all extrinsic factors could be eliminated, the problem of failed back surgery would still be a major one. This chapter is based on a review of 300 postoperative lumbar spine multiplanar CT scans performed over a 15-month period. All patients had a complete set of axial images, with sagittal and coronal reformations photographed twice: optimized once for bone definition and once for soft-tissue contrast resolution

  18. Postoperative Ileus in the Elderly

    Chih-Peng Tu

    2014-03-01

    Full Text Available Postoperative ileus is among the most common complications after surgery. Aging is associated with an increased colonic transit time, and anesthetic disturbance to colonic motility is often aggravated in the elderly. Postoperative ileus increases morbidity, prolongs the length of hospital stay, and constitutes a significant economic burden on the healthcare system. Multimodal enhanced recovery protocols, or fast-track surgeries, have been developed to improve postoperative recovery. Patient education, avoidance of perioperative fluid overload, selective use of nasogastric decompression, early ambulation, adopting a minimally invasive approach, early initiation of clear fluids, and gum chewing are all possible measures to reduce postoperative ileus. Thoracic epidural anesthesia is a well-established technique to hasten recovery, whereas insufficient data are available to ascertain the safety and efficacy of opioid-sparing analgesia in the elderly. The evidence is clear that traditional prokinetic medications are not helpful in the treatment or prevention of postoperative ileus. Early results suggest that alvimopan is a promising agent to reverse opioid-induced ileus. Since postoperative ileus is a multifactorial condition, a concerted effort is therefore necessary to prevent or decrease the duration of postoperative ileus using multimodal strategies.

    2016-08-01

    Full Text Available Purpose: While brachytherapy is often used concurrently with flap reconstruction following surgical ablation for head and neck cancer, it remains unclear whether it increases morbidity in the particularly high risk subset of patients undergoing salvage treatment for recurrent head and neck cancer (RH&NC. Material and methods : A retrospective chart review was undertaken that evaluated patients with RH&NC who underwent flap coverage after surgical re-resection and concomitant brachytherapy. The primary endpoint was flap viability, and the secondary endpoints were flap and recipient site complications. Results : In the 23 subjects included in series, flap viability and skin graft take was 100%. Overall recipient site complication rate was 34.8%, high-dose radiation (HDR group 50%, and low-dose radiation (LDR group 29.4%. There was no statistically significant difference between these groups. Conclusions : In patients who undergo flap reconstruction and immediate postoperative radiotherapy following salvage procedures for RH&NC, flap coverage of defects in combination with brachytherapy remains a safe and effective means of providing stable soft tissue coverage.

    To investigate whether malnutrition is associated with poor prognosis of patients who undergo salvage esophagectomy. We examined the association between the preoperative prognostic nutritional index (PNI) and prognosis of patients who undergo salvage esophagectomy. We conducted a single-center retrospective study and reviewed hospital patient records for tumor characteristics and patient outcomes. Univariate and multivariate survival analyses were carried out using the Cox proportional hazards regression model. Thirty-two patients with esophageal squamous cell carcinoma (ESCC) who underwent salvage esophagectomy between 1998 and 2015 at our Institute were included in this study. Univariate analysis revealed that clinical response (p=0.045), preoperative PNI (pnutritional status is associated with the prognosis of patients undergoing salvage esophagectomy.

    Correct interpretation of imaging findings in the postoperative shoulder is impaired by surgical distortion of normal anatomy and possible artifacts. Advanced postoperative imaging of the shoulder in addition to the selection of the best suited modality necessitates familiarity with the surgical procedure that has been performed and its consecutive morphological changes. This article reviews the most common arthroscopic and open techniques used for treatment of shoulder instability, lesions of the superior labral-bicipital complex, primery impingement, and rotator cuff tears, their typical postoperative imaging findings, as well as the diagnostic performance of cross sectional imaging techniques in the detection of recurrent lesions and complications.

    Postoperative imaging of the ankle can be challenging, even for the experienced radiologist. Pathological and postoperative changes to the primarily complex anatomy of the ankle with its great variety of bone structures, tendons, ligaments, and soft tissue in a very limited space may cause great difficulty in differentiating underlying pathology from expected postoperative changes and artifacts, especially in magnetic resonance imaging (MRI). Selecting the appropriate radiological modality is key to making the correct diagnosis. Therefore, knowledge of the initial and current symptoms is just as important as familiarity with the most frequently performed operations in the ankle. This article aims to give its reader a summary of the most important and frequently performed operation techniques of the ankle and discusses the expected appearance and possible complications in postoperative imaging. (orig.) [German] Die postoperative radiologische Bildgebung des Sprunggelenks kann auch fuer den erfahrenen Radiologen eine besondere Herausforderung darstellen. Die komplex aufgebaute Anatomie des Sprunggelenks, mit seinen multiplen Gelenkflaechen, Sehnen, Baendern und neurovaskulaeren Strukturen auf engstem Raum, kann durch Operationen signifikant veraendert und insbesondere in der Magnetresonanztomographie (MRT) verfaelscht dargestellt werden. Fuer eine fundierte Befundung und Beurteilung der Operationsergebnisse ist die Kenntnis der praeoperativen Diagnose, Zeitpunkt und Technik der durchgefuehrten Operation(en) sowie der aktuellen klinischen Symptomatik von grosser Bedeutung. Dieser Artikel konzentriert sich auf zu erwartende radiologische Veraenderungen und gibt Tipps zur Befundung der postoperativen MRT des Sprunggelenks bei einer Auswahl relevanter operativer Eingriffe.

    Although the use of saphenous vein grafts in free-flap salvage and extremity replantation is relatively common, their use in breast reconstruction is rare. These two case reports represent extreme alternatives for breast reconstruction flap salvage. In our normal daily practice, the overwhelming majority of elective breast reconstructions proceed smoothly. However, the occasional patient may require saphenous vein graft flap rescue for completion of the reconstruction. (c) 2008 Wiley-Liss, Inc.

    Full Text Available Salvage felling is one of the indicators of the forest health quality and stability. Most of the European Union countries monitor forest harmful agents, which account for salvage felling, in order to see trends or functionality between factors and to be able to predict their development. The systematic evidence of forest harmful agents and volume of salvage felling in Slovakia started at the Forest Research Institute in Zvolen in 1960. The paper focuses on the occurrence of the most relevant harmful agents and volume of salvage felling in the Slovak forests over the last decade. Within the 10 years period (2004–2013 salvage felling in Slovakia reached 42.31 mil. m3 of wood, which was 53.2% of the total felling. Wind and European spruce bark beetle Ips typographus damaged 78.4% of salvage wood, i.e. they were the most important pest agents. Norway spruce (Picea abies was the most frequently damaged tree species that represented the amount of 35.6 mil. m3 of wood (81.2% of total volume of salvage felling. As Norway spruce grows mostly in mountains, these regions of Central and Northern Slovakia were most affected. At the damaged localities new forests were prevailingly established with regard to suitable ecological conditions for trees, climate change scenarios and if possible, natural regeneration has been preferred. These approaches in forest stand regeneration together with silvicultural and control measures are assumed to gradually decrease the amount of salvage felling over long term perspective.

    Conclusions: High-dose IG-IMRT results in high rates of salvage and extremely low rates of serious late toxicity for patients with locally recurrent prostate cancer after cryotherapy. Although the results are encouraging, given the small number of patients in this and other series, we remain cautious with regard to this treatment and believe the use of salvage radiation therapy after cryotherapy warrants further study.

    The role of disturbance in structuring vegetation is widely recognized; however, we are only beginning to understand the effects of multiple interacting disturbances on ecosystem recovery and development. Of particular interest is the impact of post-disturbance management interventions, particularly in light of the global controversy surrounding the effects of salvage logging on forest ecosystem recovery. Studies of salvage logging impacts have focused on the effects of post-disturbance salvage logging within the context of a single natural disturbance event. There have been no formal evaluations of how these effects may differ when followed in short sequence by a second, high severity natural disturbance. To evaluate the impact of this management practice within the context of multiple disturbances, we examined the structural and woody plant community responses of sub-boreal Pinus banksiana systems to a rapid sequence of disturbances. Specifically, we compared responses to Blowdown (B), Fire (F), Blowdown-Fire, and Blowdown-Salvage-Fire (BSF) and compared these to undisturbed control (C) stands. Comparisons between BF and BSF indicated that the primary effect of salvage logging was a decrease in the abundance of structural legacies, such as downed woody debris and snags. Both of these compound disturbance sequences (BF and BSF), resulted in similar woody plant communities, largely dominated by Populus tremuloides; however, there was greater homogeneity in community composition in salvage logged areas. Areas experiencing solely fire (F stands) were dominated by P. banksiana regeneration, and blowdown areas (B stands) were largely characterized by regeneration from shade tolerant conifer species. Our results suggest that salvage logging impacts on woody plant communities are diminished when followed by a second high severity disturbance; however, impacts on structural legacies persist.

    Although the initial response to salvage (also known as, post-disturbance or sanitary) logging is known to vary among system components, little is known about longer term forest recovery. We examine forest overstory, understory, soil, and microtopographic response 25 years after a 1977 severe wind disturbance on the Flambeau River State Forest in Wisconsin, USA, a portion of which was salvage logged. Within this former old-growth hemlock-northern hardwoods forest, tree dominance has shifted from Eastern hemlock (Tsuga canadensis) to broad-leaf deciduous species (Ulmus americana, Acer saccharum, Tilia americana, Populus tremuloides, and Betula alleghaniensis) in both the salvaged and unsalvaged areas. While the biological legacies of pre-disturbance seedlings, saplings, and mature trees were initially more abundant in the unsalvaged area, regeneration through root suckers and stump sprouts was common in both areas. After 25 years, tree basal area, sapling density, shrub layer density, and seedling cover had converged between unsalvaged and salvaged areas. In contrast, understory herb communities differed between salvaged and unsalvaged forest, with salvaged forest containing significantly higher understory herb richness and cover, and greater dominance of species benefiting from disturbance, especially Solidago species. Soil bulk density, pH, organic carbon content, and organic nitrogen content were also significantly higher in the salvaged area. The structural legacy of tip-up microtopography remains more pronounced in the unsalvaged area, with significantly taller tip-up mounds and deeper pits. Mosses and some forest herbs, including Athyrium filix-femina and Hydrophyllum virginianum, showed strong positive responses to this tip-up microrelief, highlighting the importance of these structural legacies for understory biodiversity. In sum, although the pathways of recovery differed, this forest appeared to be as resilient to the compound disturbances of windthrow

    Spinal epidural hematoma (SEH) is a rare postoperative complication but can result in catastrophic neurological deficits requiring immediate surgical evacuation of the hematoma. Knowing the risk factors for postoperative SEH can help surgeons stratify patients. Therefore, to identify possible risk factors for postoperative SEH, we reviewed 6 clinical cases and examined the relation between postoperative hypertension and the risk of developing SEH. A retrospective review was conducted of 1282 consecutive patients who underwent spinal surgery at a single institution between 2010 and 2015. Of this cohort, 6 patients developed symptomatic SEH and underwent emergency hematoma evacuation. The 6 SEH patients were evaluated for previously described risk factors of postoperative hematoma formation. In particular, postoperative blood pressure measurements were reviewed. The incidence of postoperative symptomatic SEH was 0.468%. Two patients developed SEH secondary to a nonfunctional surgical drain in the early postoperative period (5 or 12 h post-surgery). Preoperative and postoperative hypertension was observed in 4 patients who developed SEH at greater than or equal to 48 h following surgery. Our findings suggest that rigorous postoperative blood pressure control may decrease the risk of SEH. © 2017 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

    Postoperative imaging of the ankle can be challenging, even for the experienced radiologist. Pathological and postoperative changes to the primarily complex anatomy of the ankle with its great variety of bone structures, tendons, ligaments, and soft tissue in a very limited space may cause great difficulty in differentiating underlying pathology from expected postoperative changes and artifacts, especially in magnetic resonance imaging (MRI). Selecting the appropriate radiological modality is key to making the correct diagnosis. Therefore, knowledge of the initial and current symptoms is just as important as familiarity with the most frequently performed operations in the ankle. This article aims to give its reader a summary of the most important and frequently performed operation techniques of the ankle and discusses the expected appearance and possible complications in postoperative imaging.

    Relapsed or primary refractory Hodgkin's lymphoma (HL) patients refractory to first-line salvage chemotherapy (first salvage) and unable to undergo high-dose chemotherapy (HDC) and autologous stem cell transplant (auto-SCT) have very poor outcome. Some patients are offered second-line salvage chemotherapy (second salvage), if they are responsive and may receive HDC auto-SCT. We identified 31 patients (18 males, 13 females) from 1996-2012 who received second salvage prior to auto-SCT. Median age at auto-SCT is 22 years. Patients were grouped as (1) relapsed-refractory (Rel:Ref): patients with prior complete response (CR) and on relapse found refractory to first salvage and received second salvage and (2) refractory-refractory (Ref:Ref): patients refractory to both primary treatment and first salvage and received second salvage. Median follow-up is 63 months (18-170). Disease status after second salvage prior to HDC was CR 16 %, partial response (PR) 71 % and stable disease 13 %. After HDC auto-SCT, CR:PR: progressive disease was observed in 18 (58 %): four (12 %): nine (29 %) patients, respectively. Five-year overall survival (OS) for whole group is 57 % (Rel:Ref vs. Ref:Ref, 73 % vs. 48 %, p = 0.48). Progression-free survival (PFS) for whole group is 52 % (Rel:Ref vs. Ref:Ref, 73 % vs. 40 % respectively, p = 0.11). Second-line salvage is a valid approach with no long-term side effects for those HL patients who do not respond to first-line salvage chemotherapy and they can be candidate of HDC and stem cell transplant with a high ORR, the PFS and OS in relapse-refractory and refractory-refractory group of patients.

    Timely assessment of acute postoperative pain is very important for pain management. No objective and reliable method to assess postoperative pain intensity exists till now. The aim of the study was to investigate the feasibility of photoplethysmography (PPG) signals in postoperative pain assessment. Thirty patients scheduled for elective abdominal surgery under general anesthesia were examined. Finger PPG signals and visual analogue scale (VAS) score were acquired before and 5, 10, 20, and 30 min after sufentanil administration when the patients were awake and transferred to the post-anesthesia care unit (PACU). During each pain rating, the patient's blood pressure, heart rate, and pulse oxygen saturation were recorded. The amplitude of alternating current (AC) and direct current (DC) extracted from finger PPG signals were analyzed, and the ratio of AC and DC (AC/DC) was calculated. Receiver operating characteristic (ROC) curves were built to assess the performance of AC and AC/DC to detect patients with VAS >4 in the PACU. After administration of sufentanil, VAS scores decreased significantly (p pain levels, but no obvious differences in blood pressures and heart rate. The area under the ROC curves were 0.754 for AC and 0.795 for AC/DC, respectively. The finger PPG signal can be used in acute postoperative pain assessment. Both AC/DC and AC had significant correlations with the pain rating levels, while blood pressure and heart rate were unreliable in pain assessment.

    The purpose of the Y-12 Old Salvage Yard scrap metal Characterization Study is to make conservative estimates of the quantities of total uranium and the wt % 235 U contained in scrap metal. The original project scope included estimates of thorium, but due to the insignificant quantities found in the yards, thorium was excluded from further analysis. Metal in three of the four Y-12 scrap metal yards were characterized. The scrap metal yard east of the PIDAS fence is managed by the Environmental Restoration Program and therefore was not included in this study. For all Y-12 Plant scrap metal shipments, Waste Transportation, Storage, and Disposal (WTSD) personnel must complete a Request for Authorization to Ship Nuclear Materials, UCN-16409, which requires the grams of total uranium, the wt % 235 U, and the grams of 235 U contained in the shipment. This information is necessary to ensure compliance with Department of Transportation regulations, as well as to ensure that the receiving facility is adhering to its operating license. This characterization study was designed to provide a technical basis for determining these necessary radioactive quantities

    On Saturday the 25th of August 1984, at 2:20 P.M., the German car ferry Olau Britannia with 800 passengers aboard rammed the rear starboard side of the French cargo ship Mont Louis. The collision occurred in the English Channel at a point 18 kilometers north of Ostend. At 7:00 P.M. the Mont Louis sank to a depth of 15 meters at a distance of several miles by rail from Antwerp. Half the ship's hull lay uncovered at low tide. The cargo included 30 type 48-Y containers, each filled with 12 tons of UF 6 , and 22 empty type 30-B containers for return of the enriched uranium. The UF 6 was to be enriched to 4% in the Soviet Union for use as fuel in nuclear power plants. The table below details the nature of the UF 6 . After salvaging operation the containers have been inspected and no damage or leaks have been detected. The accident involved no risk of radioactive or chemical contamination of the sea water. The systematic misinformation campaign by Greenpeace and news media is briefly described. (orig./HP)

  16. Freeze-drying wet digital prints: An option for salvage?

    2010-01-01

    On the occasion of the collapse of the Historical Archive of the City of Cologne in March 2009 and the ensuing salvage effort, questions were raised about the use of freeze-drying for soaked digital prints, a technique that has not yet been evaluated for these materials. This study examines the effects of immersion, air-drying, drying in a blotter stack, freezing and freeze-drying on 35 samples of major digital printing processes. The samples were examined visually before, during and after testing; evaluation of the results was qualitative. Results show that some prints were already damaged by immersion alone (e.g. bleeding inks and soluble coatings) to the extent that the subsequent choice of drying method made no significant difference any more. For those samples that did survive immersion, air-drying proved to be crucial for water-sensitive prints, since any contact with the wet surface caused serious damage. Less water-sensitive prints showed no damage throughout the entire procedure, regardless of drying method. Some prints on coated media suffered from minor surface disruption up to total delamination of the surface coating due to the formation of ice crystals during shock-freezing. With few exceptions, freeze-drying did not cause additional damage to any of the prints that hadn't already been damaged by freezing. It became clear that an understanding of the process and materials is important for choosing an appropriate drying method.

    Excellent thermal and operational stabilities of thermophilic enzymes can greatly increase the applicability of biocatalysis in various industrial fields. However, thermophilic enzymes are generally incompatible with thermo-labile substrates, products, and cofactors, since they show the maximal activities at high temperatures. Despite their pivotal roles in a wide range of enzymatic redox reactions, NAD(P)(+) and NAD(P)H exhibit relatively low stabilities at high temperatures, tending to be a major obstacle in the long-term operation of biocatalytic chemical manufacturing with thermophilic enzymes. In this study, we constructed an in vitro artificial metabolic pathway for the salvage synthesis of NAD(+) from its degradation products by the combination of eight thermophilic enzymes. The enzymes were heterologously produced in recombinant Escherichia coli and the heat-treated crude extracts of the recombinant cells were directly used as enzyme solutions. When incubated with experimentally optimized concentrations of the enzymes at 60°C, the NAD(+) concentration could be kept almost constant for 15h.

    A retrospective study was performed to assess toxicity and response rate of ifosfamide salvage treatment for dogs diagnosed with metastatic osteosarcoma (OSA). Dogs diagnosed with OSA and previously treated with standard chemotherapy were included in the study. Nineteen dogs met the inclusion criteria, and 17 dogs were evaluable for response. Ifosfamide doses ranged from 375 to 425 mg m(-2) (median dose 375 mg m(-2)), with a median of two doses administered per dog (range 1-7 doses). The overall response to ifosfamide was 11.8% [complete response (CR) = 1/17, partial response (PR) = 1/17, stable disease (SD) = 2/17, progressive disease (PD) = 13/17]. Two dogs were hospitalized due to ifosfamide toxicosis. The median survival duration from the first dose of ifosfamide to death was 95 days. Ifosfamide was well tolerated, but minor anti-tumour activity was observed. © 2012 Blackwell Publishing Ltd.

    To investigate the ability of salvage cryoablation of the prostate (SCAP) to delay the need for androgen deprivation therapy (ADT) in local recurrence after radiation therapy to the prostate using the Cryo-On-Line Database (COLD) registry. The COLD registry is comprised of a combination of retrospectively and prospectively collected data on patients undergoing primary and SCAP. Patients with local recurrence after radiation therapy were identified. Kaplan-Meier analysis was used to calculate ADT-free survival. We identified 898 patients that have undergone SCAP in the COLD registry. Overall, the calculated 5-year ADT-free survival probability was 0.713. When stratified by D'Amico risk group, 264 high-risk patients (71.9%), 234 intermediate-risk (86.7%),and 228 low-risk (87.7%) were free of ADT post-SCAP. This correlates with a 5-year ADT-free survival of 60.7, 73.9, and 82.4%, respectively. Patients with post-SCAP PSA nadir of <0.2 ng/mL had a 5 year ADT-free survival of 87.1% compared to 48.7% with a PSA nadir ≥0.2 ng/mL. Pre-operative ADT use or full versus partial gland SCAP did not have an effect on ADT use post-operatively. In 118 (55.4%) of patients with post-operative biochemical recurrence, ADT was not used. For patients with local recurrence after radiation, SCAP is an option that provides a high chance of avoiding or delaying ADT. The potential to delay ADT and its associated side effects should be a part of counseling sessions with the patient when discussing treatment options for locally recurrent prostate cancer after radiation. Avoidance of ADT is more clinically relevant than PSA elevation. © 2017 Wiley Periodicals, Inc.

    Effects of preoperative one week enteral nutrition (EN) support on the postoperative nutritional status, immune function and inflammatory response of gastric cancer patients were investigated. 106 cases of gastric cancer patients were randomly divided into preoperative one week EN group (trial group) and early postoperative EN group (control group), which were continuously treated with EN support until the postoperative 9th day according to different treatment protocols. All the patients were checked for their body weight, skinfold thickness, upper arm circumference, white blood cell count (WBC), albumin (ALB), prealbumin (PA), C-reactive protein (CRP), humoral immunity (IgA, IgG), T cell subsets (CD4, CD8 and CD4/CD8), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), etc. on the preoperative and the postoperative 1st and 10th day, respectively. PA and IgG levels of the experimental group were higher than those of the control group on the postoperative 10th day, whereas IL-6 level of the experimental group was lower than that of the control group. EN support for preoperative gastric cancer patients will improve the postoperative nutritional status and immune function, alleviate inflammatory response, and facilitate the recovery of patients.

    Purpose: The purpose was to evaluate the contralateral nodal control (CLNC) in postoperative patients with oral and oropharyngeal cancer treated with ipsilateral irradiation of the neck and primary site. Late radiation-induced morbidity was also evaluated. Methods and Materials: The study included 123 patients with well-lateralized squamous cell carcinomas treated with surgery and unilateral postoperative irradiation. Most patients had tumors of the gingiva (41%) or buccal mucosa (21%). The majority of patients underwent surgery of the ipsilateral neck (n = 102 [83%]). The N classification was N0 in 73 cases (59%), N1 or N2a in 23 (19%), and N2b in 27 cases (22%). Results: Contralateral metastases developed in 7 patients (6%). The 5-year actuarial CLNC was 92%. The number of lymph node metastases was the only significant prognostic factor with regard to CLNC. The 5-year CLNC was 99% in N0 cases, 88% in N1 or N2a cases, and 73% in N2b cases (p = 0.008). Borderline significance (p = 0.06) was found for extranodal spread. Successful salvage could be performed in 71% of patients with contralateral metastases. The prevalence of Grade 2 or higher xerostomia was 2.6% at 5 years. Conclusions: Selected patients with oral or oropharyngeal carcinoma treated with primary surgery and postoperative ipsilateral radiotherapy have a very high CLNC with a high probability of successful salvage in case of contralateral metastases. However, bilateral irradiation should be applied in case of multiple lymph node metastases in the ipsilateral neck, particularly in the presence of extranodal spread. The incidence of radiation-induced morbidity is considerably lower as observed after bilateral irradiation.

    Radiotherapy (RT) is an established treatment for patients with primary and recurrent prostate cancer. Herein, the effects of definitive and salvage RT on the composition of lymphocyte subpopulations were investigated in patients with prostate cancer to study potential immune effects. A total of 33 prostate cancer patients were treated with definitive (n = 10) or salvage RT (n = 23) after biochemical relapse. The absolute number of lymphocytes and the distribution of lymphocyte subpopulations were analyzed by multiparameter flow cytometry before RT, at the end of RT, and in the follow-up period. Absolute lymphocyte counts decreased significantly after RT in both patient groups and a significant drop was observed in the percentage of B cells directly after RT from 10.1 ± 1.3 to 6.0 ± 0.7% in patients with definitive RT and from 9.2 ± 0.8 to 5.8 ± 0.7% in patients with salvage RT. In contrast, the percentages of T and natural killer (NK) cells remained unaltered directly after RT in both patient groups. However, 1 year after RT, the percentage of CD3{sup +} T cells was significantly lower in patients with definitive and salvage RT. The percentage of regulatory T cells was slightly upregulated in primary prostate cancer patients after definitive RT, but not after salvage RT. Definitive and salvage RT exert similar effects on the composition of lymphocyte subpopulations in prostate cancer patients. Total lymphocyte counts are lower in both patient groups compared to healthy controls and further decreased after RT. B cells are more sensitive to definitive and salvage RT than T and NK cells.

    Salvage radiotherapy is the only curative treatment for patients with prostate cancer showing biochemical progression after radical prostatectomy. In this study, we evaluated the clinicopathological parameters that influence the outcome of salvage radiotherapy. Medical records of 49 patients who underwent salvage radiotherapy after radical prostatectomy from 1997 to 2008 at the Graduate School of Medicine, Kyoto University, were retrospectively reviewed. Radiotherapy was carried out with 66 Gy on the prostatic bed. Biochemical progression-free survival after salvage radiotherapy at 2, 5 and 7 years was 51.0%, 42.2% and 42.2%, respectively. Significant parameters predicting biochemical progression after salvage radiotherapy by Cox regression analysis were prostatectomy Gleason score sum ≥8 (hazard ratio 0.08; 95% confidence interval 0.03-0.22; P=0.001), prostate-specific antigen nadir after radical prostatectomy ≥0.04 ng/mL (hazard ratio 0.30; 95% confidence interval 0.13-0.69; P=0.005) and negative surgical margin (hazard ratio 0.28; 95% confidence interval 0.12-0.70; P=0.006). When the patients were subgrouped by these risk factors, the 5-year progression-free survival rates after salvage radiotherapy were 77.8%, 50.0% and 6.7% in patients with 0, 1 and ≥2 predictors, respectively. In order to discriminate favorable candidates for salvage radiotherapy, Gleason score of prostatectomy, prostate-specific antigen nadir after prostatectomy and positive surgical margin represent independent predictors. Thus, progression-free survival might be more precisely predicted according to the presence/absence of these risk factors. The significance of this risk classification should be confirmed by large prospective studies. (author)

    Purpose: Salvage radical prostatectomy (RP) may potentially cure patients who have isolated local prostate cancer recurrence after radiotherapy (RT). We report the long-term cancer control associated with salvage RP in a consecutive cohort of patients and identify the variables associated with disease progression and cancer survival. Methods and Materials: A total of 100 consecutive patients underwent salvage RP with curative intent for biopsy-confirmed, locally recurrent, prostate cancer after RT. Disease progression after salvage RP was defined as a prostate-specific antigen (PSA) level of ≥0.2 ng/mL or by initiation of androgen deprivation therapy. Cancer-specific mortality was defined as active clinical disease progression despite castration. Cox regression analysis was used to evaluate these endpoints. The median follow-up from RT was 10 years (range, 3-27 years) and from salvage RP was 5 years (range, 1-20 years). Results: Overall, the 5-year progression-free probability was 55% (95% confidence interval, 46-64%), and the median progression-free interval was 6.4 years. The preoperative PSA level was the only significant pretreatment predictor of disease progression in the multivariate analysis (p = 0.01). The 5-year progression-free probability for patients with a preoperative PSA level of 10 ng/mL was 86%, 55%, and 37%, respectively. The 10-year and 15-year cancer-specific mortality after salvage RP was 27% and 40%, respectively. The median time from disease progression to cancer-specific death was 10.3 years (95% confidence interval, 7.6-12.9). After multivariate analysis, the preoperative serum PSA level and seminal vesicle or lymph node status correlated independently with disease progression. Conclusions: Greater preoperative PSA levels are associated with disease progression and cancer-specific death. Long-term control of locally recurrent prostate cancer after definitive RT is possible when salvage RP is performed early in the course of recurrent

    Radiotherapy (RT) is an established treatment for patients with primary and recurrent prostate cancer. Herein, the effects of definitive and salvage RT on the composition of lymphocyte subpopulations were investigated in patients with prostate cancer to study potential immune effects. A total of 33 prostate cancer patients were treated with definitive (n = 10) or salvage RT (n = 23) after biochemical relapse. The absolute number of lymphocytes and the distribution of lymphocyte subpopulations were analyzed by multiparameter flow cytometry before RT, at the end of RT, and in the follow-up period. Absolute lymphocyte counts decreased significantly after RT in both patient groups and a significant drop was observed in the percentage of B cells directly after RT from 10.1 ± 1.3 to 6.0 ± 0.7% in patients with definitive RT and from 9.2 ± 0.8 to 5.8 ± 0.7% in patients with salvage RT. In contrast, the percentages of T and natural killer (NK) cells remained unaltered directly after RT in both patient groups. However, 1 year after RT, the percentage of CD3 + T cells was significantly lower in patients with definitive and salvage RT. The percentage of regulatory T cells was slightly upregulated in primary prostate cancer patients after definitive RT, but not after salvage RT. Definitive and salvage RT exert similar effects on the composition of lymphocyte subpopulations in prostate cancer patients. Total lymphocyte counts are lower in both patient groups compared to healthy controls and further decreased after RT. B cells are more sensitive to definitive and salvage RT than T and NK cells.

    Purpose: We analyzed the clinical course of patients who developed local (primary) recurrence following high-dose irradiation of squamous cell carcinoma of the supraglottic larynx. Methods and Materials: Between October 1964 and July 1991, 206 patients with previously untreated squamous cell carcinoma of the supraglottic larynx underwent radiotherapy with curative intent. Local failure occurred in 46 (22%) patients. Successful surgical salvage was defined as no evidence of recurrent cancer for at least 2 years after salvage surgery and continuously thereafter. Results: Sixteen patients did not undergo salvage surgery because of refusal (7 patients), severe medical illness (2 patients), concurrent distant metastasis (5 patients), or unresectable neck disease (2 patients). Twenty-six patients underwent total laryngectomy, and 4 patients had a voice-sparing procedure. Successful salvage was achieved in 50% of patients who underwent surgery. The rate of successful salvage did not correlate with preirradiation T-stage or time to failure after irradiation. Most of the failures after surgery were because of failure to control the primary cancer. The overall rate of postsurgical complications was 37%. No operative or perioperative deaths occurred. The 5-year survival rate for all 46 patients, calculated from the date of irradiation failure, was 20%, while the 5-year survival rate after salvage surgery for the 30 patients who underwent the procedure was 29%. Conclusion: There are few data in the literature regarding the clinical outcome in patients whose tumors are not controlled by initial radiotherapy. In the current and previous series, one-half to two-thirds of patients who developed primary failure underwent salvage surgery, which was successful in approximately half of the operated patients, leading to a 25-30% rate of long-term disease-free survival among the entire group of patients who developed failure

    Globally, expansion of non-native woody vegetation across floodplains has raised concern of increased evapotranspiration (ET) water loss with consequent reduced river flows and groundwater supplies. Water salvage programs, established to meet water supply demands by removing introduced species, show little documented evidence of program effectiveness. We use two case studies in the USA and Australia to illustrate factors that contribute to water salvage feasibility for a given ecological setting. In the USA, saltcedar (Tamarix spp.) has become widespread on western rivers, with water salvage programs attempted over a 50-year period. Some studies document riparian transpiration or ET reduction after saltcedar removal, but detectable increases in river base flow are not conclusively shown. Furthermore, measurements of riparian vegetation ET in natural settings show saltcedar ET overlaps the range measured for native riparian species, thereby constraining the possibility of water salvage by replacing saltcedar with native vegetation. In Australia, introduced willows (Salix spp.) have become widespread in riparian systems in the Murray-Darling Basin. Although large-scale removal projects have been undertaken, no attempts have been made to quantify increases in base flows. Recent studies of ET indicate that willows growing in permanently inundated stream beds have high transpiration rates, indicating water savings could be achieved from removal. In contrast, native Eucalyptus trees and willows growing on stream banks show similar ET rates with no net water salvage from replacing willows with native trees. We conclude that water salvage feasibility is highly dependent on the ecohydrological setting in which the non-native trees occur. We provide an overview of conditions favorable to water salvage.

    Purpose: To investigate the role of external beam radiotherapy (EBRT) as salvage treatment of prostate cancer after cryosurgery failure. Methods and Materials: Between 1993 and 1998, 6 patients underwent EBRT with curative intent for local recurrence of prostate cancer after cryosurgery. All 6 patients had biopsy-proven recurrence and palpable disease on digital rectal examination at the time of EBRT. The median follow-up was 34 months (range 8-46). The median prostate-specific antigen level was 2.3 ng/mL (range 0.8-4.1). No patient had evidence of metastatic disease. Two patients received hormonal therapy before beginning EBRT. No patient received hormonal therapy after EBRT completion. The median elapsed time between cryosurgery and EBRT was 3 years (range 1.5-4). The median delivered dose was 66 Gy (range 62-70.2) using a 10-MeV photon beam. An in-house-developed three-dimensional treatment planning system was used to plan delivery of the prescribed dose with conformal radiotherapy techniques. Results: After EBRT, all patients had complete resolution of palpable disease. Four patients (66%) were disease free at the time of the last follow-up. Two patients developed biochemical failure as defined by the American Society for Therapeutic Radiology and Oncology consensus definition. One of these patients had a prostate-specific antigen level of 97 ng/mL before cryosurgery. No patient developed distant metastasis during follow-up. Two patients (33%) developed proctitis; 1 case resolved with Rowasa suppositories and 1 required blood transfusion. Conclusions: Our preliminary results suggest that EBRT can render a significant number of patients biochemically free of disease and can cause complete resolution of clinically palpable disease after initial cryosurgery. The results also showed that EBRT can be given without excessive morbidity. EBRT should be considered as a treatment option in these potentially curable cases

  9. Trauma and postoperative follow-up

    Indications for the use of nuclear medicine techniques, mostly bone scintigraphy, occur in case of diagnostic problems, especially if there are discrepancies between the clinical symptoms and X-ray findings. This may happen in case of stress fractures, fractures in bones difficult to judge by X-ray imaging, and in the differentation of recent versus old fracture. A further indication for bone scanning is to assess the extent of skeletal lesions in polytrauma and in the battered child syndrome. In postoperative patients bone scanning is most frequently performed in order to assess loosening or infection of endoprosthesis. Due to bone remodelling uptake of Tc-diphosphonates varies between cemented and cementfree implants. This fact should be taken into consideration when interpreting bone scans in areas with endoprostheses. In both trauma and postoperative patients, indications for nuclear medicine imaging exist if healing is complicated. Bone scanning can be used to assess pseudoartrosis or non-union, infection, viability of grafts and bone fragments and reflex sympathetic dystrophy. In suspicious infection with positive bone scan, white blood cell or microcollid scintigraphy can be used for further differentiation. (orig./MG) [de

    Patients who drink too much have more complications after surgery. The aim of this thesis was to evaluate the evidence, possible mechanisms, and prevention of the increased postoperative morbidity in alcohol abusers, defined by a consumption of at least five drinks per day. The literature could...... be criticised for several methodological flaws. Nevertheless, the results are in agreement showing moderate to strong evidence of increased postoperative morbidity after surgical procedures on alcohol abusers. There is weak to moderate evidence of increased postoperative mortality, hospital stay, and re......-operation. The personal and economic consequences are tremendous. The incidence of alcohol abusers undergoing surgery was 7% to 49%, according to gender and diagnosis. They have been identified by a self-reported alcohol intake, which implies the possibility of underestimation. Alcohol markers could be used for a more...

    Cerebral hyperperfusion after carotid endarterectomy (CEA) results in cerebral hyperperfusion syndrome and cognitive impairment. The goal of the present study was to clarify the clinical significance of postoperative crossed cerebellar hypoperfusion (CCH) in patients with cerebral hyperperfusion after CEA by assessing brain perfusion with single-photon emission computed tomography (SPECT). Brain perfusion was quantitatively measured using SPECT and the [{sup 123}I]N-isopropyl-p-iodoamphetamine-autoradiography method before and immediately after CEA and on the third postoperative day in 80 patients with ipsilateral internal carotid artery stenosis ({>=}70%). Postoperative CCH was determined by differences between asymmetry of perfusion in bilateral cerebellar hemispheres before and after CEA. Neuropsychological testing was also performed preoperatively and at the first postoperative month. Eleven patients developed cerebral hyperperfusion (cerebral blood flow increase of {>=}100% compared with preoperative values) on SPECT imaging performed immediately after CEA. In seven of these patients, CCH was observed on the third postoperative day. All three patients with hyperperfusion syndrome exhibited cerebral hyperperfusion and CCH on the third postoperative day and developed postoperative cognitive impairment. Of the eight patients with asymptomatic hyperperfusion, four exhibited CCH despite resolution of cerebral hyperperfusion on the third postoperative day, and three of these patients experienced postoperative cognitive impairment. In contrast, four patients without postoperative CCH did not experience postoperative cognitive impairment. The presence of postoperative CCH with concomitant cerebral hyperperfusion reflects the development of hyperperfusion syndrome. Further, the presence of postoperative CCH in patients with cerebral hyperperfusion following CEA suggests development of postoperative cognitive impairment, even when asymptomatic. (orig.)

    Limited data on patterns of recurrence (local or metastatic) after salvage radical prostatectomy (SP) is available. To examine biochemical, local and metastatic patterns of recurrence in patients undergoing SP for radiation-recurrent prostate cancer. 146 patients with biopsy-proven local recurrence of prostate cancer after radiation therapy treated with SP were evaluated in a retrospective study at a single institution. All patients underwent SP by mainly two surgeons. Biochemical recurrence (BCR) after SP was defined as a serum prostate-specific antigen (PSA) level of >or=0.2 ng/ml or was defined by the initiation of androgen deprivation therapy. All predictors analyzed were determined after radiotherapy, before SP, and included PSA level, clinical stage, biopsy Gleason score, age at SP, and time interval from radiotherapy to SP. Of the 146 patients treated with SP, 65 developed BCR. The median follow-up period for recurrence-free patients was 3.8 yr; 43 patients (29%) were followed for >5 yr. Overall, the 5-yr recurrence-free probability was 54% (95% CI, 44-63%). Clinical local recurrence occurred in only one patient who also had bone metastases. Overall, there were 16 prostate cancer-specific deaths and 19 deaths from other causes. The 5-yr cumulative incidence of death from prostate cancer was 4% (95% CI, 2-11%). Pre-SP serum PSA level and biopsy Gleason score were significantly associated with death due to prostate cancer (p<0.0005 and p=0.002, respectively). This study is retrospective and included carefully selected patients treated over a long period by, mainly, two experienced surgeons. SP provides excellent local cancer control; only one patient in our series experienced a clinical local recurrence. Earlier identification of patients with persistent, viable local cancer despite radiation therapy will appropriately select patients for SP.

    Full Text Available Craniofacial trauma is often associated with orbital and ocular injuries. We report a case of a 21-year-old male with motor vehicular accident, orbital roof blow-in fracture, cerebrospinal fluid (CSF leak, and left sided globe luxation with corneal abrasion and complete conjunctival denuding. The patient was managed by a multispeciality team and the eyeball was protected by amniotic membrane graft (AMG biological dressing with novel use of inverted sterile metallic bowl as mechanical protection till the patient stabilized. During surgery, eyeball was reposited and ocular surface was reconstructed using amniotic membrane and symblepharon ring. Surgical correction and plating of the facial fractures and dural repair with autologus tensor fascia lata was done. Post surgery ocular surface was intact, ocular motility was well preserved and the globe was prephthisical. Traumatic eyeball luxation is a rare, but dramatic presentation which may occur in a blow in fracture when the intra orbital volume reduces and expels the eye ball out of the socket. This may be associated with extra ocular muscle rupture or optic nerve avulsion. The visual prognosis is nil in majority cases. However, the management is targeted towards globe preservation in view of psychological benefit and ease of cosmetic or prosthetic rehabilitation. Knowing the mechanism of luxation helps to plan the management. A stepwise approach for globe salvage is recommended. Team efforts to take care of various morbidities with special steps to safeguard the eye help to optimize outcomes.

    2017-01-01

    Full Text Available Method and device of a flexible interception and salvage system was introduced in this paper. In order to study the effect of wave motion on salvage operation, we proposed a passive wave compensation scheme that utilizes a combination of variable-pitch cylinders and accumulators, and established the mathematical vibration model of the rolling motion of the salvage compensation system. With the relationships between the stiffness coefficient and the accumulator parametric of passive compensated gas-liquid system, we determined the effective compensation stiffness range through Mathematica simulation analysis. The relationship between the roll displacement of the salvage arm and the initial volume Vo of the accumulator has been analysed. The results show that the accumulatorVo in a certain range has a great influence on the passive compensation. However, when the volume is greater than 20m3, the compensation effect is weakened, and tend to a certain value, irrespective of the passive system accumulator volume capacity, it does not achieve full compensation. The results have important guidance on the design and optimization of rolling passive compensation of the practical high sea salvage system.

    Hyperglycemia upon hospital admission in patients with ST-segment elevation myocardial infarction (STEMI) occurs frequently and is associated with adverse outcomes. It is, however, unsettled as to whether an elevated blood glucose level is the cause or consequence of increased myocardial damage....... In addition, whether the cardioprotective effect of exenatide, a glucose-lowering drug, is dependent on hyperglycemia remains unknown. The objectives of this substudy were to evaluate the association between hyperglycemia and infarct size, myocardial salvage, and area at risk, and to assess the interaction...... between exenatide and hyperglycemia.

    Laparoscopic myomectomy (LM) can be associated with significant bleeding. To identify factors influencing the postoperative hemoglobin (Hb) drop after LM. This is a retrospective, single-center study. We evaluated data of 150 consecutive patients undergoing LM due to intramural myomas between 2010 and 2015. The median age of the patients was 37 (23-53) years. The mean diameter of the largest myoma was 5.7 ±2.3 (1.5-12) cm. The mean surgical time was 83 ±38 (35-299) min. The median number of sutures was 3 (1-11). The mean postoperative Hb drop was 1.6 ±1.2 (0-6) g/dl, and the mean estimated blood loss was 261 ±159 (50-1700) ml. In the univariate analysis, the postoperative Hb drop correlated with the duration of surgery (p < 0.001), diameter of the largest myoma (p < 0.001), cumulative myoma weight (p < 0.001), and number of sutures (p < 0.001), but not with patients' age or number of intramural myomas. In the multivariable analysis, the surgical time ( β = 0.395, p < 0.001), diameter of the largest myoma ( β = 0.292, p = 0.03) and preoperative Hb concentration ( β = 0.299, p < 0.001) predicted the postoperative Hb change. Surgical time and dominant myoma diameter are independent predictors of the postoperative Hb drop after LM.

    Full Text Available Introduction. Chronic pancreatitis (CP is considered an inflammatory disease that may cause varying degrees of pancreatic dysfunction. Conservative and surgical treatment options are available depending on dysfunction severity. Presentation of Case. A 36-year-old male with history of heavy alcohol consumption and diagnosed CP underwent a duodenal-preserving pancreatic head resection (DPPHR or Beger procedure after conservative treatment failure. Refractory pain was reported on follow-up three months after surgery and postoperative imaging uncovered stones within the main pancreatic duct and intestinal dilation. The patient was subsequently subjected to another surgical procedure and intraoperative findings included protein plugs within the main pancreatic duct and pancreaticojejunal anastomosis stricture. A V-shaped enlargement and main pancreatic duct dilation in addition to the reconstruction of the previous pancreaticojejunal anastomosis were performed. The patient recovered with no further postoperative complications in the follow-up at an outpatient clinic. Discussion. Main duct and pancreaticojejunal strictures are an unusual complication of the Beger procedure but were identified intraoperatively as the cause of patient’s refractory pain and explained intraductal protein plugs accumulation. Conclusion. Patients that undergo Beger procedures should receive close outpatient clinical follow-up in order to guarantee postoperative conservative treatment success and therefore guarantee an early detection of postoperative complications.

    Salvage biosynthesis of nicotinamide adenine dinucleotide (NAD(+)) from nicotinamide (NAM) lowers NAM levels and replenishes the critical molecule NAD(+) after it is hydrolyzed. This pathway is emerging as a regulator of multiple biological processes. Here we probe the contribution of the NAM-NAD(+) salvage pathway to muscle development and function using Caenorhabditis elegans. C. elegans males with mutations in the nicotinamidase pnc-1, which catalyzes the first step of this NAD(+) salvage pathway, cannot mate due to a spicule muscle defect. Multiple muscle types are impaired in the hermaphrodites, including body wall muscles, pharyngeal muscles and vulval muscles. An active NAD(+) salvage pathway is required for optimal function of each muscle cell type. However, we found surprising muscle-cell-type specificity in terms of both the timing and relative sensitivity to perturbation of NAD(+) production or NAM levels. Active NAD(+) biosynthesis during development is critical for function of the male spicule protractor muscles during adulthood, but these muscles can surprisingly do without salvage biosynthesis in adulthood under the conditions examined. The body wall muscles require ongoing NAD(+) salvage biosynthesis both during development and adulthood for maximum function. The vulval muscles do not function in the presence of elevated NAM concentrations, but NAM supplementation is only slightly deleterious to body wall muscles during development or upon acute application in adults. Thus, the pathway plays distinct roles in different tissues. As NAM-NAD(+) biosynthesis also impacts muscle differentiation in vertebrates, we propose that similar complexities may be found among vertebrate muscle cell types. Copyright © 2010 Elsevier Inc.

    We report our experience in salvaging spinal metastases initially irradiated with stereotactic body radiation therapy (SBRT), who subsequently progressed with imaging-confirmed local tumor progression, and were re-irradiated with a salvage second SBRT course to the same level. From a prospective database, 56 metastatic spinal segments in 40 patients were identified as having been irradiated with a salvage second SBRT course to the same level. In addition, 24 of 56 (42.9%) segments had initially been irradiated with conventional external beam radiation therapy before the first course of SBRT. Local control (LC) was defined as no progression on magnetic resonance imaging at the treated segment, and calculated according to the competing risk model. Overall survival (OS) was evaluated for each patient treated by use of the Kaplan-Meier method. The median salvage second SBRT total dose and number of fractions was 30 Gy in 4 fractions (range, 20-35 Gy in 2-5 fractions), and for the first course of SBRT was 24 Gy in 2 fractions (range, 20-35 Gy in 1-5 fractions). The median follow-up time after salvage second SBRT was 6.8 months (range, 0.9-39 months), the median OS was 10.0 months, and the 1-year OS rate was 48%. A longer time interval between the first and second SBRT courses predicted for better OS (P=.02). The crude LC was 77% (43/56), the 1-year LC rate was 81%, and the median time to local failure was 3.0 months (range, 2.7-16.7 months). Of the 13 local failures, 85% (11/13) and 46% (6/13) showed progression within the epidural space and paraspinal soft tissues, respectively. Absence of baseline paraspinal disease predicted for better LC (Pinitial SBRT is a feasible and efficacious salvage treatment option. Copyright © 2015 Elsevier Inc. All rights reserved.

    Total nuclear DNA can be empirically subdivided into low salt-soluble (LS) DNA (75-80%), high salt-soluble (HS) DNA (18-23%), and nuclear matrix-associated (NM) DNA which remains tightly bound to the nuclear matrix (∼2%). The most-newly replicated DNA is that associated with the nuclear matrix in regenerating rat liver. Analyses of the DNA fractions after various pulse times revealed that the salvage and de novo pathway DNA precursors investigated were incorporated preferentially into NM-DNA at early pulse times, after which the radioactivity became progressively incorporated into HS- and LS-DNA, respectively. These results support two models of nuclear matrix-associated DNA replication, proposed previously, and a third model presented in this dissertation. In addition, the incorporation of de novo pathway precursors lagged significantly (> 10 minutes) behind the incorporation of precursors entering through the salvage pathway. Channeling of salvage pathway precursors to DNA replication sites would explain the more rapid uptake of salvage precursors into NM-DNA than de novo precursors. To investigate the possibility of this heretofore in vitro phenomenon, the incorporation of the salvage precursor, ( 3 H)deoxythymidine, and the de novo precursor, ( 14 C)orotic acid, into NM-DNA and dTTP was examined in regenerating rat liver. There was no significant difference between the incorporation pattern of ( 14 C)orotic acid into NM-DNA thymine and that of ( 14 C)orotic acid into soluble dTTP. Contrastingly, the salvage pathway precursor, ( 3 H)deoxythymidine, labeled NM-DNA before labeling the dTTP pool

    The indications for and the efficacy of radiation therapy after radical operation for patients with prostate cancer are not clear. We analyzed the treatment results of adjuvant radiotherapy and salvage radiotherapy after radical prostatectomy. Between September 1997 and November 2004, 57 patients received adjuvant radiotherapy or salvage radiotherapy after radical prostatectomy. Fifteen patients received radiation therapy because of positive margins and/or extracapsular invasion in surgical specimens (adjuvant group). Forty-two patients received radiation therapy because of rising prostate-specific antigen (PSA) during follow-up (salvage group). Radiation therapy was delivered to the fossa of the prostate±seminal vesicles by a three-dimensional (3-D) conformal technique to a total dose of 60-66 Gy (median, 60 Gy). Biochemical control was defined as the maintenance of a PSA level of less than 0.2 ng/ml. The median follow-up period after radiation therapy was 33 months (range, 12-98 months). Three-year biochemical control rates were 87% for the adjuvant group and 61% for the salvage group. For patients in the salvage group treated without hormone therapy, the preradiation PSA value was the most significant factor for the biochemical control rate. The 3-year biochemical control rate was 93% in patients whose preradiation PSA was 0.5 ng/ml or less and 29% in patients whose preradiation PSA was more than 0.5 ng/ml. No severe adverse effects (equal to or more than grade 3) were seen in treated patients. Radiation therapy after radical prostatectomy seemed to be effective for adjuvant therapy and for salvage therapy in patients with a preradiation PSA of 0.5 ng/ml or less. Also, radiation to the fossa of the prostate±seminal vesicles, to a total dose of 60-66 Gy, using a three-dimensional (3-D) conformal technique, seemed to be safe. (author)

  9. Limb Salvage After Failed Initial Operative Management of Bimalleolar Ankle Fractures in Diabetic Neuropathy.

    Ankle fractures in patients with diabetes mellitus (DM) can be difficult to manage, especially in the presence of peripheral neuropathy. In patients who fail initial operative management, attempts at limb salvage can be challenging, and no clear treatment algorithm exists. This study examined outcomes of different procedures performed for limb salvage in this population. This study retrospectively reviewed 17 patients with DM complicated by peripheral neuropathy who sustained a bimalleolar ankle fracture and failed initial operative management. Patients were treated with revision open reduction internal fixation (ORIF) (3/17), closed reduction external fixation (CREF) (8/17), or primary ankle joint fusion (3/17 tibiotalocalcaneal fusion with hindfoot nail [TTCN] and 3/17 with tibiotalar arthrodesis using plates and screws [TTA]). Median follow-up was 20 months. The overall rate of limb salvage was 82.3% (14/17). All patients who went on to amputation presented with infection and were treated initially with CREF (3/3). All patients who achieved successful limb salvage ended up with a clinically fused ankle joint (14/14); 9 underwent a primary or delayed formal fusion and 5 had a clinically fused ankle joint at study conclusion after undergoing revision ORIF or CREF with adjunctive procedures. This small study suggests that in this complicated group of patients it is difficult to achieve limb salvage with an end result of a functional ankle joint. CREF can be a viable option in cases where underlying infection or poor bone quality is present. Treatment with revision ORIF frequently requires supplementary external fixator or tibiotalar Steinman pin placement for additional stability. All patients who underwent revision ORIF ended up with clinically fused ankle joints at the end of the study period. Primary fusion procedures (TTA, TTCN) were associated with a high rate of limb salvage and a decreased number of operations. Level III, retrospective case series.

    Purpose: Radiation therapy following resection of a brain metastasis increases the probability of disease control at the surgical site. We analyzed our experience with postoperative stereotactic radiosurgery (SRS) as an alternative to whole-brain radiotherapy (WBRT), with an emphasis on identifying factors that might predict intracranial disease control and overall survival (OS). Methods and Materials: We retrospectively reviewed all patients through December 2008, who, after surgical resection, underwent SRS to the tumor bed, deferring WBRT. Multiple factors were analyzed for time to intracranial recurrence (ICR), whether local recurrence (LR) at the surgical bed or “distant” recurrence (DR) in the brain, for time to WBRT, and for OS. Results: A total of 49 lesions in 47 patients were treated with postoperative SRS. With median follow-up of 9.3 months (range, 1.1-61.4 months), local control rates at the resection cavity were 85.5% at 1 year and 66.9% at 2 years. OS rates at 1 and 2 years were 52.5% and 31.7%, respectively. On univariate analysis (preoperative) tumors larger than 3.0 cm exhibited a significantly shorter time to LR. At a cutoff of 2.0 cm, larger tumors resulted in significantly shorter times not only for LR but also for DR, ICR, and salvage WBRT. While multivariate Cox regressions showed preoperative size to be significant for times to DR, ICR, and WBRT, in similar multivariate analysis for OS, only the graded prognostic assessment proved to be significant. However, the number of intracranial metastases at presentation was not significantly associated with OS nor with other outcome variables. Conclusions: Larger tumor size was associated with shorter time to recurrence and with shorter time to salvage WBRT; however, larger tumors were not associated with decrements in OS, suggesting successful salvage. SRS to the tumor bed without WBRT is an effective treatment for resected brain metastases, achieving local control particularly for tumors up to

    2012-01-01

    Fever in the postoperative period in children undergoing surgery for congenital heart disease is fairly common and tends to cause anxiety to both the surgeon and the patient. Such fever is associated with the metabolic response to trauma, systemic response to the cardiopulmonary bypass, hypothermia, presence of drainage tubes, drugs, blood transfusion as well as infections. Establishing the diagnosis requires proper assessment of the patient with focused history, targeted physical examination and judicious use of investigations with the knowledge of the common causes

    The invention refers to the separation of solids which are carried over during evaporation of salvaged oil (oil recovered from used oil or fat). They are removed by exposing the oil vapour to an acceleration of 500 g to 20,000g in a hot gas cyclone. Subsequently the cleaned gas is converted to fission gas in a fission gas generator using an air-water gas mixture and is taken to the combustion equipment. By this process salvaged oil and heavy hydrocarbons can be used for burning in Diesel engines without previous refining.

    Postoperative chylothorax is a relatively rare but potentially fatal complication caused by iatrogenic injury to thoracic duct system, with an incidence ranging from 2 to 4% after major lung surgery or esophagectomy. The pathophysiologic features of chylothorax include dehydration, loss of nutrients and immunological components. Intraopreative prevention is the first step for the management, and treatment options include conservative therapy, percutaneous intervention, and redo-operation. Although the treatment algorithm has not been standardized, chylothorax which is refractory to conservative treatment, or that with high output greater than 1,000 ml/day should be treated aggressively with thoracic duct embolization or redo-operation in a timely fashion. We herein review the anatomy and physiology of thoracic duct system and describe the overview of prevention and each theapeutic options of postoperative chylothorax.

    Postoperative management of patients suffering from symptoms of the temporomandibular joint does not differ considerably from the one of preoperative examination protocols. Knowledge of previous surgery helps to plan patient work-up and to interpret normal postoperative findings (eminectomy, discectomy, susceptibility artefacts from metallic residues..) and typical complications (intraarticular loose bodies, dislocations, avascular necrosis, foreign body granulomatous reactions) appropriately.

    Radical cystectomy followed by urinary diversion or reconstruction (RC) is a standard treatment for patients with muscle-invasive bladder cancer. In these operations, a high frequency of complications, especially postoperative infection, has been reported. However, there have only been a few studies about postoperative anaerobic bacterial infection. To clarify the significance and role of anaerobic bacteria in postoperative infection, we retrospectively analyzed cases in which postoperative infection by these organisms developed. A total of 126 patients who underwent RC from 2006 to 2010 were included in this study. Various types of postoperative infection occurred in 66 patients. Anaerobic bacterial infections were detected with cultures for urine and blood in one case, for blood in two cases, and for surgical wound pus in four. The frequency of postoperative anaerobic bacterial infection in RC was less than that of colon surgery. However, this study revealed the possible development of a nonnegligible number of postoperative anaerobic bacterial infections. Therefore, we should consider anaerobic bacteria as possible pathogens in postoperative infection after RC.

    Objective: To evaluate the influence of modest endotoxemia on postoperative antithrombin deficiency and cholestasis. Summary Background Data: It has not been determined whether endotoxin translocation in small amounts is a physiological phenomenon or whether it is a potential health hazard. Methods: Blood endotoxin, antithrombin III (ATIII), secretory immunoglobulin A (sIgA), which was selected as a marker of cholestasis, C-reactive protein (CRP), and α-1-antitrypsin (AAT) concentrations were measured from the 20 patients undergoing curative gastrectomy for gastric cancer preoperatively and postoperatively. Portal and systemic blood samples were taken for the analysis of endotoxin and interleukin-6 (IL-6) concentrations during surgery in these patients. Results: Although plasma endotoxin levels showed a significant increase during surgery, we did not find a correlation with ATIII, sIgA, CRP, and IL-6 levels. Systemic blood endotoxin levels during surgery correlated with a postoperative rise of serum AAT levels. Plasma ATIII levels transiently decreased on the first and third postoperative day, and sIgA levels were shown to increase on the seventh postoperative day. There was a weak relationship between the extent of postoperative endotoxemia and a reduction in ATIII concentrations. Conclusions: The influence of modest endotoxemia on postoperative antithrombin deficiency and cholestasis was limited, and increased translocational endotoxemia during abdominal surgery may be a physiological phenomenon to trigger off an acute-phase protein response.

    2014-01-01

    The standard of care for extremity soft tissue sarcomas continues to be negative-margin limb salvage surgery. Radiotherapy is frequently used as an adjunct to decrease local recurrence. No differences in survival have been found between preoperative and postoperative radiotherapy regimens. However, it is uncertain if the use of a postoperative boost in addition to preoperative radiotherapy reduces local recurrence rates. This retrospective review evaluated patients who received preoperative radiotherapy (n = 49) and patients who received preoperative radiotherapy with a postoperative boost (n=45). The primary endpoint analysed was local recurrence, with distant metastasis and death due to sarcoma analysed as secondary endpoints. Wilcoxon rank-sum test and either χ 2 or Fisher's exact test were used to compare variables. Multivariable regression analyses were used to take into account potential confounders and identify variables that affected outcomes. No differences in the proportion or rate of local recurrence, distant metastasis or death due to sarcoma were observed between the two groups (P>0.05). The two groups were similarly matched with respect to demographics such as age, race and sex and tumour characteristics including excision status, tumour site, size, depth, grade, American Joint Committee on Cancer stage, chemotherapy receipt and histological subtype (P>0.05). The postoperative boost group had a larger proportion of patients with positive microscopic margins (62% vs 10%; P<0.001). No differences in rates of local recurrence, distant metastasis or death due to sarcoma were found in patients who received both pre- and postoperative radiotherapy when compared with those who received only preoperative radiotherapy.

  6. The scientific basis for patient blood management.

    Murphy, M F; Goodnough, L T

    2015-08-01

    Patient blood management is an increasingly used term to describe an evidence-based, multidisciplinary approach to optimising the care of patients who might need transfusion. It encompasses measures to avoid transfusion such as anaemia management without transfusion, cell salvage and the use of anti-fibrinolytic drugs to reduce bleeding as well as restrictive transfusion. It ensures that patients receive the optimal treatment, and that avoidable, inappropriate use of blood and blood components is reduced. This paper provides an overview of the scientific basis for patient blood management with a focus on the increasing evidence for restrictive rather than liberal transfusion practice and the use of electronic blood ordering and decision support to facilitate its implementation.

    Substantial blood loss during spine surgery can result in increased patient morbidity and mortality. Proper preoperative planning and communication with the patient, anesthesia team, and operating room staff can lessen perioperative blood loss. Advances in intraoperative antifibrinolytic agents and modified anesthesia techniques have shown promising results in safely reducing blood loss. The surgeon's attention to intraoperative hemostasis and the concurrent use of local hemostatic agents also can lessen intraoperative bleeding. Conversely, the use of intraoperative blood salvage has come into question, both for its potential inability to reduce the need for allogeneic transfusions as well as its cost-effectiveness. Allogeneic blood transfusion is associated with elevated risks, including surgical site infection. Thus, desirable transfusion thresholds should remain restrictive.

    Nemec, S.; Czerny, C.; Formanek, M.

    2007-01-01

    The radiological interpretation of postoperative changes of the paranasal sinuses requires knowledge of why and how the surgical intervention was performed and what the basic clinical findings were. It is important to know whether there was an inflammation, a reconstructive procedure, or a tumorous process. Multidetector computed tomography (MDCT) evaluated in a high-resolution bone window level setting represents the method of choice for imaging after nonfunctional and functional procedures after inflammatory changes as well as for imaging after reconstructive surgery because of facial trauma or before dental implantation. In the postoperative follow-up of tumor patients contrast-enhanced MDCT evaluated in a soft tissue window and bone window and especially magnetic resonance imaging (MRI) represent the standard. In many cases it is possible to differentiate tumor recurrence from inflammation with the help of contrast-enhanced multiplanar MRI and to detect bone marrow changes prior to CT. (orig.)

    2015-03-01

    Singultus, or hiccups, is a common medical condition. Despite exponential leaps in medicine, the pathophysiologic cause remains poorly defined. Persistent singultus has been associated with conditions such as pulmonary embolism and myocardial infarction. Singultus is also a well-known postoperative complication. The criterion standard of care for patients with singultus involves ruling out lethal pathologic causes, attempting physical stimulation with Valsava maneuvers or drinking water, and, if no relief has been achieved, administering drugs to ease the symptoms. The authors report a case of a man whose postoperative singultus was successfully managed with osteopathic manipulative treatment. This approach addresses many of the possible underlying neuromechanical causes of the aberrant reflex with minimal potential for adverse effects. Physicians should consider osteopathic manipulative treatment in the care of patients with singultus. © 2015 The American Osteopathic Association.

    Delirium is a common complication in postoperative, critically ill patients. The mechanism of postoperative delirium is not well understood but many studies have shown significant associations between benzodiazepine use, alcohol withdrawal and cirrhosis, and an increased risk of delirium. We aimed to investigate a possible link with alterations of gamma-aminobutyric acid (GABA) activity. A prospective observational investigation of 40 patients > 20 years old who had undergone elective surgery with general anaesthesia and were expected to need postoperative intensive care for more than 48 hours. We assessed postoperative delirium using the confusion assessment method in the intensive care unit at 1 hour after the operation and on postoperative Day (POD) 1 and POD 2. We collected blood samples for measurement of plasma GABA concentrations before the operation and on POD 1 and 2. Postoperative delirium and perioperative plasma GABA concentrations in patients with and without delirium. Postoperative delirium occurred in 13 of the patients. Patients with delirium had significantly higher Acute Physiology and Chronic Health Evaluation II scores than patients without delirium. The mean plasma GABA concentration on POD 2 was significantly lower in patients with delirium than in those without delirium. After adjustment of relevant variables, plasma GABA concentration on POD 2 was independently associated with postoperative delirium. Plasma GABA level on POD 2 has a significant independent association with postoperative delirium.

    1993-09-01

    Questions persist about the management of postoperative chylothorax in infants and children. Our experience with postoperative chylothorax over the most recent decade (1980 to 1990) has been reviewed. The type and amount of drainage, data from cardiac catheterization and echocardiography, operative decisions and details, and eventual outcomes have been cataloged. All patients were initially treated with total gut rest, with operation reserved for unabated drainage. Chylothorax developed postoperatively in 15 infants and 11 children (18 with a cardiac procedure and 8 with a noncardiac procedure). The average age was 3.1 years. Spontaneous cessation and cure occurred in 19 (73.1%) of these 26 patients, with an average drainage duration of 11.9 days (range, 4 to 30 days). Those for whom operation was chosen drained preoperatively for an average of 29.2 days (range, 25 to 40 days). There were no deaths in either group. Complications were lymphopenia (2 patients) and fungal sepsis (1 patient). The amount of drainage per day was not significantly different between patients treated operatively and those treated nonoperatively. Failure of nonoperative management was associated with venous hypertension from increased right-sided cardiac pressures or central venous thrombosis (p < 0.05, Fisher's exact test). Presumably this increased pressure is transmitted to the lymphatic system. These patients should be identified early and considered for thoracic duct suture or pleuroperitoneal shunting.

  15. Minimal Invasive Urologic Surgery and Postoperative Ileus

    Directory of Open Access Journals (Sweden)

    Fouad Aoun

    2015-07-01

    Full Text Available Postoperative ileus (POI is the most common cause of prolonged length of hospital stays (LOS and associated healthcare costs. The advent of minimal invasive technique was a major breakthrough in the urologic landscape with great potential to progress in the future. In the field of gastrointestinal surgery, several studies had reported lower incidence rates for POI following minimal invasive surgery compared to conventional open procedures. In contrast, little is known about the effect of minimal invasive approach on the recovery of bowel motility after urologic surgery. We performed an overview of the potential benefit of minimal invasive approach on POI for urologic procedures. The mechanisms and risk factors responsible for the onset of POI are discussed with emphasis on the advantages of minimal invasive approach. In the urologic field, POI is the main complication following radical cystectomy but it is rarely of clinical significance for other minimal invasive interventions. Laparoscopy or robotic assisted laparoscopic techniques when studied individually may reduce to their own the duration and prevent the onset of POI in a subset of procedures. The potential influence of age and urinary diversion type on postoperative ileus is contradictory in the literature. There is some evidence suggesting that BMI, blood loss, urinary extravasation, existence of a major complication, bowel resection, operative time and transperitoneal approach are independent risk factors for POI. Treatment of POI remains elusive. One of the most important and effective management strategies for patients undergoing radical cystectomy has been the development and use of enhanced recovery programs. An optimal rational strategy to shorten the duration of POI should incorporate minimal invasive approach when appropriate into multimodal fast track programs designed to reduce POI and shorten LOS.

    Full text: To determine the overall survival and gastrointestinal toxicity for patients treated with salvage definitive chemo-radiotherapy after primary surgery for locoregional relapse of oesophageal carcinoma. A retrospective review of 525 patients who had a resection for oesophageal or oesophagogastric carcinoma at Princess Alexandra Hospital identified 14 patients treated with salvage definitive radiotherapy or chemo-radiotherapy, following localized recurrence of their disease. We analysed the patient and treatment characteristics to determine the median overall survival as the primary end point. Gastrointestinal toxicity was examined to determine if increased toxicity occurred when the stomach was irradiated within the intrathoracic radiotherapy field. The median overall survival for patients treated with curative intent using salvage definitive chemo-radiotherapy was 16 months and the 2-year overall survival is 21%. One patient is in clinical remission more than 5 years after therapy. Age <60 years old and nodal recurrence were favourable prognostic factors. Treatment compliance was 93% with only one patient unable to complete the intended schedule. Fourteen per cent of patients experienced grade 3 or 4 gastrointestinal toxicity. Salvage definitive chemo-radiotherapy should be considered for good performance status patients with oesophageal carcinoma who have a locoregional relapse after primary surgery. The schedule is tolerable with low toxicity and an acceptable median survival

    Gastric tube necrosis after esophagus cancer surgery is a rare but critical situation. Salvage reconstruction of the esophagus remains a challenging procedure for head and neck surgeons. Historically, surgeons have employed a two-stage salvage surgery consisting of debridement followed by reconstruction. While this procedure generates good results, the time to restart oral alimentation is long. The present report describes the case of a 62-year-old male who developed gastric tube necrosis 3 days after undergoing surgery for thoracic-cervical esophageal cancer and immediate reconstruction with the retrosternal gastric pullup technique. He was treated with debridement and simultaneous free jejunum transfer 4 days after the primary surgery. He was able to restart oral alimentation 10 days after the salvage surgery. This rapid return to oral alimentation is a major advantage of the one-stage immediate esophagus salvage reconstruction. Another advantage is the ease of the reconstructive procedure: the absence of scarring and prolonged inflammation, which are disadvantages of the two-stage procedure, meant that recipient vessel selection and anastomosis were uncomplicated. The one-step procedure may be particularly useful in cases where the inflammation is discovered early.

    Full Text Available Aim: Many etiological factors play a role in the occurrence of postoperative empyema. We aimed to define the effects of these factors on the development of empyema. Material and Method: Two hundred and eighty-eight cases from our clinic who underwent tube thoracostomy and/or were operated due to any cause out of the primary empyema  between August 2009 and May 2010 were prospectively studied in terms of empyema development. Data comprised gender, age, chemoradiotherapy, surgical procedure, intraoperative thoracic lavage with povidone-iodine, emergency surgery status, sharing the same room with other cases with empyema, primary disease, additional comorbidity, operation duration, drain number, complication, number of patients in the room, and drain discontinuation and hospitalization duration. Blood leukocyte-neutrophil count was ordered in all cases at 3-day intervals, and fluid culture specimens were simultaneously collected from cases with drains. Drainage fluid culture specimens were evaluated with “Automated Identification and Antibiotic Susceptibility Testing” using standard procedures. Empyema cases who developed clinical manifestation and/or with bacterial growth in culture specimens were studied in terms of risk factors. The findings were analyzed using SPSS (version 16. Results: The results showed that gender, age, chemoradiotherapy, surgical procedure, intraoperative thoracic lavage with povidone-iodine, emergency surgery status, and sharing a same room with other empyema cases were not significantly correlated with the risk of empyema development. Contribution of the primary disease (p<0.05, additional comorbidity (p<0.05, operation duration (p<0.05, drain number (p<0.05, complication (p<0.05, number of people in the room (p<0.05, drain discontinuation time (p<0.05 and hospitalization duration (p<0.05 were found to be significant in the development of postoperative empyema.

    Full Text Available Background: The purpose of the present study was to evaluate the clinical utility of Mangled extremity severity score (MESS in severely injured lower limbs. Materials and Methods: Retrospectively 25 and prospectively 36 lower limbs in 58 patients with high-energy injuries were evaluated with the use of MESS, to assist in the decision-making process for the care of patients with such injuries. Difference between the mean MESS scores for amputated and salvaged limbs was analyzed. Results: In the retrospective study 4.65 (4.65 ± 1.32 was the mean score for the salvaged limbs and 8.80 (8.8 ± 1.4 for the amputated limbs. In the prospective study 4.53 (4.53 ± 2.44 was the mean score for the salvaged limbs and 8.83 (8.83 ± 2.34 for the amputated limbs. There was a significant difference in the mean scores for salvaged and amputated limbs. Retrospective 21 (84% and prospective 29 (80.5% limbs remained in the salvage pathway six months after the injury. Conclusion: MESS could predict amputation of severely injured lower limbs, having score of equal or more than 7 with 91% sensitivity and 98% specificity. There was a significant difference in the mean MESS scores in the prospective study (n=36, 4.53 (4.53 ± 2.44 in thirty salvaged limbs (83.33% and 8.83 (8.83 ± 2.34 in six amputated limbs (16.66% with a P -value 0.002 ( P -value < 0.01. Similarly there was a significant difference in the mean MESS score in the retrospective study (n=25, 4.65 (4.65 ± 1.32 in twenty salvaged limbs (80% and 8.80 (8.8 ± 1.4 in five amputated limbs (20% with a P -value 0.00005 ( P -value < 0.01. MESS is a simple and relatively easy and readily available scoring system which can help the surgeon to decide the fate of the lower extremity with a high-energy injury.

    2014-10-01

    Purpose: Local failure after definitive stereotactic body radiation therapy (SBRT) for early-stage non-small cell lung cancer (NSCLC) is uncommon. We report the safety and efficacy of SBRT for salvage of local failure after previous SBRT with a biologically effective dose (BED) of ≥100 Gy{sub 10}. Methods and Materials: Using an institutional review board–approved lung SBRT registry, we identified all patients initially treated for early-stage NSCLC between August 2004 and January 2012 who received salvage SBRT for isolated local failure. Failure was defined radiographically and confirmed histologically unless contraindicated. All patients were treated on a Novalis/BrainLAB system using ExacTrac for image guidance, and received a BED of ≥100 Gy{sub 10} for each SBRT course. Tumor motion control involved a Bodyfix vacuum system for immobilization along with abdominal compression. Results: Of 436 patients treated from August 2004 through January 2012, we identified 22 patients with isolated local failure, 10 of whom received SBRT for salvage. The median length of follow-up was 13.8 months from salvage SBRT (range 5.3-43.5 months). Median tumor size was 3.4 cm (range 1.7-4.8 cm). Two of the 10 lesions were “central” by proximity to the mediastinum, but were outside the zone of the proximal bronchial tree. Since completing salvage, 3 patients are alive and without evidence of disease. A fourth patient died of medical comorbidities without recurrence 13.0 months after salvage SBRT. Two patients developed distant disease only. Four patients had local failure. Toxicity included grade 1-2 fatigue (3 patients) and grade 1-2 chest wall pain (5 patients). There was no grade 3-5 toxicity. Conclusions: Repeat SBRT with a BED of ≥100 Gy{sub 10} after local failure in patients with early-stage medically inoperable NSCLC was well tolerated in this series and may represent a viable salvage strategy in select patients with peripheral tumors ≤5 cm.

    Outcome and toxicity profiles of salvage stereotactic ablative radiation strategies for recurrent pre-irradiated brain metastases are poorly defined. This study compared risk-benefit profiles of upfront and salvage iodine-125 brachytherapy (SBT) for small brain metastases. As the applied SBT treatment algorithm required histologic proof of metastatic brain disease in all patients, we additionally aimed to elucidate the value of biopsy before SBT. Patients with small untreated (n = 20) or pre-irradiated (n =28) suspected metastases intended for upfront or salvage SBT, respectively, were consecutively included. Temporary iodine-125 implants were used (median reference dose: 50 Gy, median dose rate: 15 cGy/h). Cumulative biologically effective doses (BED) were calculated and used for risk assessment. Treatment toxicity was classified according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer (RTOG/EORTC) criteria. Upfront SBT was initiated in 20 patients and salvage SBT in 23. In 5 patients, salvage SBT was withheld because of proven radiation-induced lesions. Treatment groups exhibited similar epidemiologic data except for tumor size (which was slightly smaller in the salvage group). One-year local/distant tumor control rates after upfront and salvage SBT were similar (94 %/65 % vs. 87 %/57 %, p = 0.45, respectively). Grade I/II toxicity was suffered by 2 patients after salvage SBT (cumulative BED: 192.1 Gy{sub 3} and 249.6 Gy{sub 3}). No toxicity-related risk factors were identified. SBT combines diagnostic yield with effective treatment in selected patients. The low toxicity rate in the salvage group points to protective radiobiologic characteristics of continuous low-dose rate irradiation. Upfront and salvage SBT are similarly effective and safe. Histologic reevaluation should be reconsidered after previous radiotherapy to avoid under- or overtreatment. (orig.) [German] Daten zu Risiko und Effizienz ablativer

    Full Text Available Purpose : Salvage treatments for localized radiorecurrent prostate cancer can be performed safely when a focal and image guided approach is used. Due to the low toxicity, the opportunity exists to investigate a second salvage treatment when a second locally recurrent prostate cancer occurs. Here, we describe a second salvage treatment procedure of 4 patients. Material and methods : Four patients with a pathologically proven second local recurrence were treated in an outpatient magnetic resonance imaging (MRI-guided setting with a single fraction of 19 Gy focal high-dose-rate brachytherapy (HDR-BT. Delineation was performed using choline-PET-CT or a 68Ga-PSMA PET in combination with multiparametric 3 Tesla MRI in all four patients. Toxicity was measured using common toxicity criteria for adverse events (CTCAE version 4.0. Results : With a median follow-up of 12 months (range, 6-15, there were 2 patients with biochemical recurrence as defined by the Phoenix-definition. There were no patients with grade 3 or more toxicity. In all second salvage HDR-BT treatments, the constraints for rectum, bladder, and urethra were met. Median treatment volume (GTV was 4.8 cc (range, 1.9-6.6 cc. A median of 8 catheters (range, 6-9 were used, and the median dose to the treatment volume (GTV was a D95: 19.3 Gy (SD 15.5-19.4 Gy. Conclusions : Second focal salvage MRI-guided HDR-BT for a select group of patients with a second locally recurrent prostate cancer is feasible. There was no grade 3 or more acute toxicity for these four patients.

    Forest fires are a regular occurrence in the Mediterranean basin. High severity fires and post-fire management can affect biological, chemical and physical properties of soil, including the composition and abundance of soil microbial communities. Salvage logging is a post-fire management strategy, which involves the removal of burnt wood from land after a fire. The main objective of this work was to evaluate the impact of post-fire salvage logging and microaggregation on soil microbial communities, specifically on the abundance of nitrogen cyclers and, thus, the potential of the soil for microbial nitrogen cycling. The abundance of nitrogen cyclers was assessed by quantification of microbial nitrogen cycling genes in soil DNA, including nifH (involved in nitrogen fixation), nirS/K and nosZ (involved in denitrification), amoA-B and amoA-Arch (involved in bacterial and archaeal nitrification, respectively). It was demonstrated that salvage logging reduced bacterial load post-fire when compared to tree retention control and resulted in significant changes to the abundance of functional bacteria involved in nitrogen cycling. Microbial gene pools involved in various stages of the nitrogen cycle were larger in control soil than in soil subjected to post-fire salvage logging and were significantly correlated with organic matter, available phosphorous, nitrogen and aggregate stability. The microaggregate fraction of the soil, which has been associated with greater organic carbon, was shown to be a hotspot for nitrogen cyclers particularly under salvage logging. The impact of post-fire management strategies on soil microbial communities needs to be considered in relation to maintaining ecosystem productivity, resilience and potential impact on climate change.

    2006-01-01

    Purpose: The purpose of this study was to evaluate the role of [ 18 F] fluorodeoxyglucose positron emission tomography (FDG-PET) in influencing salvage treatment decision making for locally persistent nasopharyngeal carcinoma (NPC). Methods and Materials: A total of 33 NPC patients with histologic persistence at nasopharynx 1 to 6 weeks after a full course of radiotherapy underwent both computed tomography (CT) and FDG-PET/CT simulation at the same treatment position. The salvage treatment decisions, with regard to the decision to offer salvage treatment and the definition of gross tumor volume (GTV), were made before knowledge of the FDG-PET findings. Subsequently the salvage treatment decisions were made again based on the FDG-PET findings and compared with the pre-FDG-PET decisions. Results: All 33 patients were referred for salvage treatment in the pre-FDG-PET decision. After knowledge of the FDG-PET results, the decision to offer salvage treatment was withdrawn in 4 of 33 patients (12.1%), as no abnormal uptake of FDG was found at nasopharynx. Spontaneous remission was observed in repeat biopsies and no local recurrence was found in these 4 cases. For the remaining 29 patients, GTV based on FDG-PET was smaller than GTV based on CT in 24 (82.8%) cases and was greater in 5 (17.2%) cases, respectively. The target volume had to be significantly modified in 9 of 29 patients (31%), as GTV based on FDG-PET images failed to be enclosed by the treated volume in the salvage treatment plan performed based on GTV based on CT simulation images. Conclusion: Use of FDG-PET was found to influence the salvage treatment decision making for locally persistent NPC by identifying patients who were not likely to benefit from additional treatment and by improving accuracy of GTV definition in salvage treatment planning

    Backround Sugammadex is a reversal agent with well known advantages but it’s effects on haemostasis and bleeding have been a topic of interest. Septoplasty is a common surgical procedure with postoperative respiratory complications and bleeding. The aim of this study is to investigate the effects of sugammadex on postoperative coagulation parameters and bleeding after septoplasty procedure. Material/Methods In this randomized controlled study, fifty patients were grouped into two groups; neostigmine (Group N) vs. sugammadex (Group S). For the evaluation of PT, aPTT and INR, blood samples were taken for at the postoperative 120th minutes and alteration of these values with respect to preoperative values were documented. Postoperative bleeding was measured by evaluating the amount of blood absorbed on the nasal tip dressing during 3 hours postoperatively. Results Postoperative bleeding amount was significantly higher in the Group S compared to Group N (p=0.013). No significant difference was observed between two groups according to coagulation parameters (PT; p=0.953, aPTT; p=0.734, INR; p=0.612). Conclusions Sugammadex was associated with higher amount of postoperative bleeding than neostigmine in septoplasty patients. In surgical procedures having high risk of bleeding the safety of sugammadex need to be verified. PMID:26271275

    To evaluate the effectiveness and tolerance of postoperative external radiotherapy for patients with intracranial meningiomas. The records of thirty three patients with intracranial meningiomas who were treated with postoperative external irradiation at our institution between Feb, 1988 and Nov, 1999 were retrospectively analyzed. Median age of patients at diagnosis was 53 years with range of 17 to 68 years. Sites of involvement were parasagital, cerebral convexity, sphenoid ridge, parasellar and tentorium cerebella. Of 33 evaluated patients, 15 transitional, 10 meningotheliomatous, 4 hemangiopericytic, 3 atypical and 1 malignant meningioma were identified. Four patients underwent biopsy alone and remaining 29 patients underwent total tumor resection. A dose of 50 to 60 Gy was delivered in 28-35 daily fractions over a period of 5 to 7 weeks. Follow-up period ranged from 12 months to 8 years. The actuarial survival rates at 5 and 7 years for entire group of patients were 78% and 67%, respectively. The corresponding disease free survival rates were 73% and 61 %, respectively. The overall local control rate at 5 years was 83%. One out of 25 patients in benign group developed local failure, while 4 out of 8 patients in malignant group did local failure (p <0.05), Of 4 patients who underwent biopsy alone, 2 developed local failure. There was no significant difference in 5 year actuarial survival between patients who underwent total tumor resection and those who did biopsy alone. Patients whose age is under 60 showed slightly better survival than those whose age is 60 or older, although this was not statistically significant. There was no documented late complications in any patients. Based on our study, we might conclude that postoperative external beam radiotherapy tends to improve survival of patients with intracranial meningiomas comparing with surgery alone

Sixty-six surgically resected residual or recurrent basal cell carcinomas of the head and neck region were irradiated postoperatively by means of orthovoltage X-rays at the Netherlands Cancer Institute between January 2000 and February 2015. After a median follow-up duration of 30.5 months, only 5 recurrences were reported. The 5-year local control rates at 1, 3, and 5 years were 100%, 87%, and 87%, respectively. The 5-year local control rate was 92% for immediate postoperative radiotherapy of incompletely resected basal cell carcinomas, 90% for recurrences after 1 previously performed excision, and 71% for multiple recurrences, namely, a history of more than 1 excision ( P = .437). Acute toxicity healed spontaneously within 3 months. Late toxicities were mild. Radiotherapy by means of orthovoltage X-ray is an excellent alternative for re-excision in case of incompletely resected or recurrent basal cell carcinomas that are at risk of serious functional and cosmetic impairments after re-excision, with a 5-year local control rate of 87% and a low toxicity profile.

    In general, late side effects after salvage radiotherapy (RT) for prostate cancer are below 10%. Patients with impaired DNA repair ability and genetic instability can have significantly increased reactions after RT. We present a patient who experienced severe side effects after additive RT for prostate cancer and died from the complications 25 months after RT. Imaging (MR) is shown as well as three-color fluorescence in situ hybridization. The blood sample testing revealed that radiosensitivity was increased by 35-55%. We undertook a review of the literature to give an overview over the tests established that are currently considered useful. This case highlights that the identification of patients with increased radiosensitivity is an important task in radiation protection. Groups of patients who should be screened have to be found and corresponding research facilities have to be set up. (orig.) [de

    Between December 1979 and September 1989, 23 patients with craniopharyngioma who underwent surgery and postoperative radiation therapy were retrospectively evaluated to assess the efficacy of this management at the Department of Therapeutic Radiology, Seoul National University Hospital. Total removal of tumor was attempted in all patients. Of these, surgeons tried total removal in eight patients, but revealed residual mass by postoperative CT, and partial removal was done in 15 patients. The morphology of tumor on the operative finding was grouped into three types : cystic 13 (57%), solid 4 (17%), and mixed 6 (26%). Cystic type was predominant in {<=}20 years old group. Actuarial overall survival rates at 5 and 10 years were 95% and 81% respectively and actuarial tumor control rates were 74% and 50%. Surgical extent was not related to the survival rates(p=0.41). Pediatric and adolescent Patients(age of {<=}20 year) had a trend of better survival than that of adult patients(p=0.10). The results indicated that limited surgical excision followed by radiation therapy is recommended when total excision is not possible.

    Conversion disorder is a condition in which psychological stress in response to difficult situations manifests as physical symptoms. Here, we report a case of postoperative coma due to conversion disorder in an elderly oral cancer patient. An 82-year-old woman was referred to Tokyo Dental College Chiba Hospital with a mass lesion on the tongue. A biopsy revealed a well-differentiated squamous cell carcinoma. Surgical treatment was performed for the tongue carcinoma and tracheotomy for management of the airway. On postoperative day 5, the patient exhibited loss of consciousness (Glasgow Coma Scale: E1, VT, M1; Japan Coma Scale: III-300). The patient's vital signs were all normal, as were the results of a full blood count, brain-CT, MRI, and MRA. Only the arm dropping test was positive. Therefore, the cause of the coma was diagnosed as conversion disorder. Seven hours later, the patient showed a complete recovery.

    Purpose: We report our experience in salvaging spinal metastases initially irradiated with stereotactic body radiation therapy (SBRT), who subsequently progressed with imaging-confirmed local tumor progression, and were re-irradiated with a salvage second SBRT course to the same level. Methods and Materials: From a prospective database, 56 metastatic spinal segments in 40 patients were identified as having been irradiated with a salvage second SBRT course to the same level. In addition, 24 of 56 (42.9%) segments had initially been irradiated with conventional external beam radiation therapy before the first course of SBRT. Local control (LC) was defined as no progression on magnetic resonance imaging at the treated segment, and calculated according to the competing risk model. Overall survival (OS) was evaluated for each patient treated by use of the Kaplan-Meier method. Results: The median salvage second SBRT total dose and number of fractions was 30 Gy in 4 fractions (range, 20-35 Gy in 2-5 fractions), and for the first course of SBRT was 24 Gy in 2 fractions (range, 20-35 Gy in 1-5 fractions). The median follow-up time after salvage second SBRT was 6.8 months (range, 0.9-39 months), the median OS was 10.0 months, and the 1-year OS rate was 48%. A longer time interval between the first and second SBRT courses predicted for better OS (P=.02). The crude LC was 77% (43/56), the 1-year LC rate was 81%, and the median time to local failure was 3.0 months (range, 2.7-16.7 months). Of the 13 local failures, 85% (11/13) and 46% (6/13) showed progression within the epidural space and paraspinal soft tissues, respectively. Absence of baseline paraspinal disease predicted for better LC (P<.01). No radiation-induced vertebral compression fractures or cases of myelopathy were observed. Conclusion: A second course of spine SBRT, most often with 30 Gy in 4 fractions, for spinal metastases that failed initial SBRT is a feasible and efficacious salvage treatment option.

    Purpose: To review the impact of high–dose radiotherapy (RT) in the postprostatectomy salvage setting on long-term biochemical control and distant metastases–free survival, and to identify clinical and pathologic predictors of outcomes. Methods and Materials: During 1988–2007, 285 consecutive patients were treated with salvage RT (SRT) after radical prostatectomy. All patients were treated with either three-dimensional conformal RT or intensity-modulated RT. Two hundred seventy patients (95%) were treated to a dose ≥66 Gy, of whom 205 (72%) received doses ≥70 Gy. Eighty-seven patients (31%) received androgen-deprivation therapy as a component of their salvage treatment. All clinical and pathologic records were reviewed to identify treatment risk factors and response. Results: The median follow-up time after SRT was 60 months. Seven-year actuarial prostate-specific antigen (PSA) relapse-free survival and distant metastases–free survival were 37% and 77%, respectively. Independent predictors of biochemical recurrence were vascular invasion (p 0.4 ng/mL (p < 0.01), androgen-deprivation therapy (p = 0.03), Gleason score ≥7 (p = 0.02), and seminal vesicle involvement (p = 0.05). Salvage RT dose ≥70 Gy was not associated with improvement in biochemical control. A doubling time <3 months was the only independent predictor of metastatic disease (p < 0.01). There was a trend suggesting benefit of SRT dose ≥70 Gy in preventing clinical local failure in patients with radiographically visible local disease at time of SRT (7 years: 90% vs. 79.1%, p = 0.07). Conclusion: Salvage RT provides effective long-term biochemical control and freedom from metastasis in selected patients presenting with detectable PSA after prostatectomy. Androgen-deprivation therapy was associated with improvement in biochemical progression-free survival. Clinical local failures were rare but occurred most commonly in patients with greater burden of disease at time of SRT as reflected by

    Background: This study analyzed the outcome of salvage radiotherapy for biochemical failure after radical prostatectomy (RP). By comparing the outcomes for patients who received RT alone and for those who received combined RT and hormonal therapy, we assessed the potential benefits of hormonal therapy. Patients and Methods: This cohort was comprised of 101 patients who received salvage RT between 1990 and 2001 for biochemical failure after RP. Fifty-nine of these patients also received hormone. Margin status (positive vs. negative), extracapsular extension (yes vs. no), seminal vesicle involvement (yes vs. no), pathologic stage, Gleason score, pre-RP PSA, post-RP PSA, pre-RT PSA, hormonal use, radiotherapy dose and technique, RP at M. D. Anderson Cancer Center, and time from RP to salvage RT were analyzed. Statistically significant variables were used to construct prognostic groups. Results: Independent prognostic factors for the RT-alone group were margin status and pre-RT PSA. RP at M. D. Anderson Cancer Center was marginally significant (p = 0.06) in multivariate analysis. Pre-RT PSA was the only significant prognostic factor for the combined-therapy group. We used a combination of margin status and pre-RT PSA to construct a prognostic model for response to the salvage treatment based on the RT group. We identified the favorable group as those patients with positive margin and pre-RT PSA ≤0.5 ng/mL vs. the unfavorable group as otherwise. This stratification separates patients into clinically meaningful groups. The 5-year PSA control probabilities for the favorable vs. the unfavorable group were 83.7% vs. 61.7% with radiotherapy alone (p = 0.03). Androgen ablation seemed to be most beneficial in the unfavorable group. Conclusion: After prostatectomy, favorable-group patients may fare well with salvage radiotherapy alone. These patients may be spared the toxicity of androgen ablation. The other patients may benefit most from a combined approach with hormonal

    We read with great interest, the case report on ischemic optic neuropathy (1). We would like to add a few points concerning the blood supply of the optic nerve and the correlation with the development of post-operative ischemic neuropathy. Actually, the perioperative or post-operative vision loss (postoperative ischemic neuropathy) is most likely due to ischemic optic neuropathy. Ischemic optic neuropathy (2) is classified as an anterior ischemic optic neuropathy (AION) and posterior ischemic optic neuropathy (PION). This classification is based on the fact that blood supply (2) to the anterior segment of the optic nerve (part of the optic nerve in the scleral canal and the optic disc) is supplied by short posterior ciliary vessels or anastamotic ring branches around the optic nerve. The posterior part of the optic canal is relatively less perfused, and is supplied by ophthalmic artery and central fibres are perfused by a central retinal artery. So, in the post-operative period, the posterior part of the optic nerve is more vulnerable for ischemia, especially, after major surgeries (3), one of the theories being hypotension or anaemia (2) and resultant decreased perfusion. The onset of PION is slower than the anterior ischemic optic neuropathy. AION on the other hand, is usually spontaneous (idiopathic) or due to arteritis, and is usually sudden in its onset. The reported case is most likely a case of PION. The role of imaging, especially the diffusion weighted magnetic resonance imaging, is very important because the ophthalmoscopic findings in early stages of PION is normal, and it may delay the diagnosis. On the other hand, edema of the disc is usually seen in the early stages of AION.

    Objective To determine the efficacy of atherectomy for limb salvage compared with open bypass in patients with critical limb ischemia. Methods Ninety-nine consecutive bypass and atherectomy procedures performed for critical limb ischemia between January 2003 and October 2006 were reviewed. Results A total of 99 cases involving TASC C (n = 43, 44%) and D (n = 56, 56%) lesions were treated with surgical bypass in 59 patients and atherectomy in 33 patients. Bypass and atherectomy achieved similar 1-year primary patency (64% vs 63%; P = .2). However, the 1-year limb salvage rate was greater in the bypass group (87% vs 69%; P = .004). In the tissue loss subgroup, there was a greater limb salvage rate for bypass patients versus atherectomy (79% vs 60%; P = .04). Conclusions Patients with critical limb ischemia may do better with open bypass compared with atherectomy as first-line therapy for limb salvage. PMID:19640919

    Treatment options for patients with recurrent disease after radical prostatectomy include salvage radiotherapy of the prostatic bed and/or androgen deprivation therapy. To establish an effective treatment strategy for recurrent disease after radical prostatectomy, we retrospectively analyzed the outcome of salvage radiation monotherapy in such cases. Data from 61 men who had undergone salvage radiation monotherapy for biochemical recurrent disease after radical prostatectomy were retrospectively reviewed. In all patients, salvage radiotherapy consisted of iraradiation to the prostatic bed (70 Gy) using three-dimensional conformal radiotherapy techniques. Treatment outcome was analyzed to identify predictive factors of salvage radiotherapy. The biochemical recurrence-free survival after salvage radiation monotherapy at 2 and 5 years was 55% and 38%, respectively. Cox proportional regression models revealed that the independent predictive factors for biochemical recurrence were Gleason Score ≥ 8, negative surgical margin, and PSA velocity ≥ 0.38 ng/mL/year. Negative surgical margin and PSA velocity ≥ 0.8 ng/mL/year were significantly associated with poor response in the serum PSA levels after salvage radiotherapy. Based on our findings, we propose a treatment strategy for biochemical recurrent disease after radical prostatectomy. Patients with Gleason score ≤ 7, positive surgical margin, and PSA velocity < 0.38 ng/mL/year are categorized the most favorable group, so that eradication by salvage radiation monotherapy could be expected. Other patients could be divided to two groups depending on surgical margin status and PSA velocity: 1) patients who might require combination of SRT and short-term androgen deprivation therapy and 2) patients who should be treated by androgen deprivation monotherapy

    During an 8-year period, 21 patients with keloids (27 keloids) were treated with keloidectomy and post-operative interstitial radiotherapy by an iridium 192 wire. Only one patient had been previously treated by corticoids, without results. A dose of 12 Gy (three patients) to 15 Gy (18 patients) was delivered at a point 2.5 mm from the axis of the wire. The follow-up time was from 2 - 104 months. The success rate, at 7 months, was close to 88%. Ao recurrence occurred in three patients without relation to the method used, the lesion-age or the localization of the lesions. There were no side-effects. This method represents an effective, non-constraining and safe treatment for keloids if the contra-indications are respected

    Purpose: To investigate the clinical factors independently predictive of long-term severe urinary sequelae after postprostatectomy radiotherapy. Patients and Methods: Between 1993 and 2005, 742 consecutive patients underwent postoperative radiotherapy with either adjuvant (n = 556; median radiation dose, 70.2 Gy) or salvage (n = 186; median radiation dose, 72 Gy) intent. Results: After a median follow-up of 99 months, the 8-year risk of Grade 2 or greater and Grade 3 late urinary toxicity was almost identical (23.9% vs. 23.7% and 12% vs. 10%) in the adjuvant and salvage cohorts, respectively. On univariate analysis, acute toxicity was significantly predictive of late Grade 2 or greater sequelae in both subgroups (p <.0001 in both cases), and hypertension (p = .02) and whole-pelvis radiotherapy (p = .02) correlated significantly in the adjuvant cohort only. The variables predictive of late Grade 3 sequelae were acute Grade 2 or greater toxicity in both groups and whole-pelvis radiotherapy (8-year risk of Grade 3 events, 21% vs. 11%, p = .007), hypertension (8-year risk, 18% vs. 10%, p = .005), age {<=} 62 years at RT (8-year risk, 16% vs. 11%, p = .04) in the adjuvant subset, and radiation dose >72 Gy (8-year risk, 19% vs. 6%, p = .007) and age >71 years (8-year risk, 16% vs. 6%, p = .006) in the salvage subgroup. Multivariate analysis confirmed the independent predictive role of all the covariates indicated as statistically significant on univariate analysis. Conclusions: The risk of late Grade 2 or greater and Grade 3 urinary toxicity was almost identical, regardless of the RT intent. In the salvage cohort, older age and greater radiation doses resulted in a worse toxicity profile, and younger, hypertensive patients experienced a greater rate of severe late sequelae in the adjuvant setting. The causes of this latter correlation and apparently different etiopathogenesis of chronic damage in the two subgroups were unclear and deserve additional investigation.

    Full Text Available OBJECTIVE: To assess hematological and biochemical features of splenic effluent blood and their influence on the rise of hematological values after splenectomy. METHODS: we studied 20 patients undergoing surgical treatment for schistosomatic portal hypertension. We collected blood samples for CBC, coagulation, bilirubin and albumin in the splenic vein (perioperative and peripheral blood (immediately pre and postoperative periods. RESULTS: the splenic blood showed higher values of red blood cells, hemoglobin, hematocrit, platelet count, total leukocytes, neutrophils, lymphocytes, monocytes, eosinophils and basophils, as well as reduction of laboratory coagulation parameters in relation to peripheral blood collected preoperatively. In the postoperative peripheral blood there was an increase in the overall leukocytes and in their neutrophil component, and decreased levels of basophils, eosinophils and lymphocytes. The other postoperative variables of complete blood count and coagulation tests were not different compared with the splenic blood. The albumin values were lower postoperatively when compared to preoperative and splenic blood. There were higher values of direct bilirubin in the postoperative period when compared with the preoperative and splenic blood. Postoperative indirect bilirubin was lower compared to its value in the splenic blood. CONCLUSION: hematological and biochemical values of splenic effluent blood are higher than those found in peripheral blood in the presence of schistosomal splenomegaly. However, the splenic blood effluent is not sufficient to raise the blood levels found after splenectomy.

    Agrobacterium fabrum induces tumor growth in susceptible plant species. The upregulation of virulence genes that occurs when the bacterium senses plant-derived compounds is enhanced by acidic pH and limiting inorganic phosphate. Nutrient starvation may also trigger the stringent response, and purine salvage is among the pathways expected to be favored under such conditions. We show here that phosphate limitation induces the stringent response, as evidenced by production of (p)ppGpp, and that the xdhCSML operon encoding the purine salvage enzyme xanthine dehydrogenase is upregulated ∼15-fold. The xdhCSML operon is under control of the TetR family transcription factor XdhR; direct binding of ppGpp to XdhR attenuates DNA binding, and the enhanced xdhCSML expression correlates with increased cellular levels of (p)ppGpp. Xanthine dehydrogenase may also divert purines away from salvage pathways to form urate, the ligand for the transcription factor PecS, which in the plant pathogen Dickeya dadantii is a key regulator of virulence gene expression. However, urate levels remain low under conditions that produce increased levels of xdhCSML expression, and neither acidic pH nor limiting phosphate results in induction of genes under control of PecS. Instead, expression of such genes is induced only by externally supplemented urate. Taken together, our data indicate that purine salvage is favored during the stringent response induced by phosphate starvation, suggesting that control of this pathway may constitute a novel approach to modulating virulence. Because bacterial purine catabolism appears to be unaffected, as evidenced by the absence of urate accumulation, we further propose that the PecS regulon is induced by only host-derived urate.

    Purpose: To evaluate the long-term results of salvage radiotherapy (SRT) for Hodgkin's lymphoma after chemotherapy failure. Methods and Materials: We reviewed 81 patients undergoing SRT for persistent or recurrent Hodgkin's lymphoma after chemotherapy; 19 also received conventional-dose salvage chemotherapy. Results: At SRT, the median patient age was 31 years. Of the 81 patients, 81% had Stage I-II, 25.9% had B symptoms, 14.8% had bulky disease, and 7.4% had extranodal disease. A less than a complete response (CR) to the last chemotherapy regimen occurred in 47%. SRT was generally limited to one side of the diaphragm, and the median dose was 36 Gy. After SRT, 75% of patients achieved a CR, with 82% retaining durable in-field control. In-field failure was associated with less than a CR to the last chemotherapy regimen (p = 0.0287). Most failures were at distant sites, with 60% in previously involved sites. The 10-year freedom from treatment failure and overall survival rates were 32.8% and 45.7%, respectively. The adverse prognostic factors for freedom from treatment failure were age >50 years (p 50 years (p < 0.001), B symptoms (p = 0.002), and less than a CR to the last chemotherapy regimen (p = 0.002). Favorable cohorts had a 10-year freedom from treatment failure rate of 51% and overall survival rate of 92%. Conclusions: Salvage radiotherapy is effective for selected patients with Hodgkin's lymphoma after chemotherapy failure and should be considered for incorporation into salvage programs

  8. Natural recovery and leaf water potential after fire influenced by salvage logging and induced drought stress

    Full Text Available Salvage logging is one of the most common emergency actions in the short-term management after a fire. Several studies have been carried out and some obtained positive results which incite to carry it out but other, found negative effects on seedling establishment and regeneration. In addition, climatic changes will have large impacts on vegetation productivity and resilience since the regional models for south-eastern Spain predicts a rainfall decrease of about 20% and temperature increase of 4.5 ºC. Our aim was to determine how short-term forest management and induced drought affect the ecosystem recovery in Aleppo pine stands naturally recovered after a fire.In summer 2009, a mid-high severity fire burned 968 ha of Aleppo pine (Pinus halepensis Mill. forest in south-eastern Spain. Six months later, a salvage logging was carried out. The Aleppo pine recruitment was negligible. During summer 2010, twelve square plots (2m x 2m were set in the three scenarios: control, salvaged and drought induced. The surface cover and soil water availability for three dominant understory species were recorded in four field campaigns: Spring-2010, Fall-2010, Spring-2011 and Fall-2011.The season, management and the target species showed significant differences in growing and water stress. In general, Esparto grass showed lower water stress, mainly in Fall, a higher increase of total coverage. Both effects were showing their highest values in non-salvaged areas and no drought. Changes in leaf water potential and soil water content after the drought season influence the survival and development of individuals.Our results indicate that soil water content and ecosystem response can be modified by short-term silvicultural treatments. Therefore, management after fire could cause opposite effects to those initially foreseen, since they depend on fire severity, and type of ecosystem management response. So, their application must be evaluated and assessed before

    Existing indices of coronary conductance (hyperemic flow-versus-pressure slope index, FPSI, and zero flow pressure, Pzf) have been developed as measures of microcoronary resistance. These indices, however, refer to cases of normal hearts, and there are no reports studying these indices following acute myocardial infarction. In this study, we investigated whether FPSI and Pzf truly measure the extent of myocardial salvage after successful reperfusion therapy. We also developed a new index of zero pressure flow, Fzp. Nineteen patients who underwent successful reperfusion therapy to the proximal portion of the left anterior descending artery (LAD) were studied. After successful reperfusion therapy, a Doppler wire was placed into the LAD. Aortic pressure was recorded in real time. Results from the aortic pressure and flow meter were combined to produce FPSI, Pzf, and Fzp. All cases underwent a resting thallium (Tl) and BMIPP scintigram within five days of successful reperfusion therapy. Infarcted myocardium was estimated using a severity score calculated from the Tl scintigraphy (TlSS), and the BMIPP (BMIPPSS) was estimated using a severity score. Patients with a TlSS/BMIPPSS ratio of less than 0.4 were assigned to the successful salvage group (group S), while the others were assigned to the failed salvage group (group F). FPSI of group F was 1.91 +/- 0.26 m/sec and of group S was 0.92 +/- 0.43 m/sec (P < 0.01). Pzf of group F was 51 +/- 3 mmHg and of group S was 51 +/- 5 mmHg (NS). Fzp of group F was -98 +/- 16 cm/sec and of group S was -46 +/- 4 cm/sec (P < 0.05). FPSI and the new index of Fzp were useful in estimating the extent of myocardial salvage. Our results suggest that the Pzf index could not differentiate between the two groups.

    We report a novel application of balloon angioplasty to recanalise a chronically occluded remote endarterectomy superficial femoral artery. This patient previously had two occluded surgical bypass grafts in an attempt to revascularise the limb and presented with critical limb ischaemia and necrotic foot ulcerations. Following the angioplasty, the patient showed significant improvement in rest pain and healing of the ulcerations. This technique may be useful for limb salvage in patients where surgical options have been exhausted.

    Full Text Available Management of recurrent dislocation of total hip arthroplasty is often a challenging and daunting task. Re-revision of such a total hip prosthesis may not be easy as the removal of a well-fixed, fully coated stem is extremely difficult. We managed to salvage instability in three revision hip cases in which the fully coated stem had subsided by using a bioball universal neck adapter without changing the femoral stem or acetabular cup.

    Full Text Available It is known that pharyngalgia is very common after tonsillectomy. It should be emphasized that the intensity of pain after adenoidectomy in children is not less important than after adenotonsillectomy. Despite the availability of standardized pain assessment scales and existing postoperative analgesia recommendations, unresolved postoperative pain still occurs in children. The research included 117 children with an average age of 7.5 ± 0.4 years, who underwent adenoidectomy at the Department of Anesthesiology and Intensive Care of "Regional Children’s Clinical Hospital" of Kharkov city in 2014. Depending on the method of general anesthesia, patients were divided into 3 groups: group I (n = 41 those who received propofol in combination with fentanyl; group II (n = 40 those who received sevoflurane in combination with fentanyl; group III (n = 36 those who received thiopental sodium combined with fentanyl. We monitored the heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, BIS-index, heart rate variability, respiration rate, and SpO2. We determined the levels of cortisol and insulin in the blood serum, glucose level, the ratio of cortisol/insulin was calculated. Assessment of the efficiency of postoperative analgesia was performed using the Wong-Baker FACES Pain Scale («Faces» and the Oucher Scale. The result of analysis of the intensity of postoperative pain determined that at the 1st hour after the operation by the «Faces» and Oucher scales, it was significantly higher in patients of group II compared with the patients of group I and group III. The morning after the operation there was no significant difference in the pain scales, and the number of scale points showed that children from all groups did not have pain. According to the data of ANOVA it was determined that only the patients in group I with indicator ΔBIS-index «intubation – traumatic moment of operation» experienced postoperative pain

  13. Overlapping Bark Beetle Outbreaks, Salvage Logging and Wildfire Restructure a Lodgepole Pine Ecosystem

    2018-02-01

    Full Text Available The 2010 Church’s Park Fire burned beetle-killed lodgepole pine stands in Colorado, including recently salvage-logged areas, creating a fortuitous opportunity to compare the effects of salvage logging, wildfire and the combination of logging followed by wildfire. Here, we examine tree regeneration, surface fuels, understory plants, inorganic soil nitrogen and water infiltration in uncut and logged stands, outside and inside the fire perimeter. Subalpine fir recruitment was abundant in uncut, unburned, beetle-killed stands, whereas lodgepole pine recruitment was abundant in cut stands. Logging roughly doubled woody fuel cover and halved forb and shrub cover. Wildfire consumed all conifer seedlings in uncut and cut stands and did not stimulate new conifer regeneration within four years of the fire. Aspen regeneration, in contrast, was relatively unaffected by logging or burning, alone or combined. Wildfire also drastically reduced cover of soil organic horizons, fine woody fuels, graminoids and shrubs relative to unburned, uncut areas; moreover, the compound effect of logging and wildfire was generally similar to wildfire alone. This case study documents scarce conifer regeneration but ample aspen regeneration after a wildfire that occurred in the later stage of a severe beetle outbreak. Salvage logging had mixed effects on tree regeneration, understory plant and surface cover and soil nitrogen, but neither exacerbated nor ameliorated wildfire effects on those resources.

    This study aimed to evaluate if variation in management of blunt splenic injury (BSI) among Level I trauma centers is associated with different outcomes related to the use of splenic artery embolization (SAE). All adult patients admitted for BSI from 2008 to 2010 at 4 Level I trauma centers were reviewed. Use of SAE was determined, and outcomes of spleen salvage and nonoperative management (NOM) failure were evaluated. A priori, a 10% SAE rate was used to group centers into high- or low-use groups. There were 1,275 BSI patients. There were intercenter differences in age, injury severity, and grade of spleen injury (Spleen Injury Scale [SIS]). Mortality was similar by center; however, BSI treatment varied significantly by center. Overall, SAE use was highest at center A compared with B, C, and D (19%, 11%, 1%, and 4%, respectively; p trauma centers. Centers with higher rates of SAE use have higher spleen salvage and less NOM failure. SAE was shown to be an independent predictor of spleen salvage. Therapeutic study, level IV.

    Nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), which is derived from NAD, have important roles as a redox carriers in metabolism. A combination of de novo and salvage pathways contribute to the biosynthesis of NAD in all organisms. The pathways and enzymes of the NAD salvage pathway in yeast and animals, which diverge at nicotinamide, have been extensively studied. Yeast cells convert nicotinamide to nicotinic acid, while mammals lack the enzyme nicotinamidase and instead convert nicotinamide to nicotinamide mononucleotide. Here we show that Arabidopsis thaliana gene At2g22570 encodes a nicotinamidase, which is expressed in all tissues, with the highest levels observed in roots and stems. The 244-residue protein, designated AtNIC1, converts nicotinamide to nicotinic acid and has a Km value of 118 +/- 17 microM and a Kcat value of 0.93 +/- 0.13 sec(-1). Plants homozygous for a null AtNIC1 allele, nic1-1, have lower levels of NAD and NADP under normal growth conditions, indicating that AtNIC1 participates in a yeast-type NAD salvage pathway. Mutant plants also exhibit hypersensitivity to treatments of abscisic acid and NaCl, which is correlated with their inability to increase the cellular levels of NAD(H) under these growth conditions, as occurs in wild-type plants. We also show that the growth of the roots of wild-type but not nic1-1 mutant plants is inhibited and distorted by nicotinamide.

Since 2004 we have been developing therapeutic possibilities for these patients. Methods. We retrospectively analyzed a cohort of 41 patients with a BCR of PCa and a mean followup of 40.3±20.8 months. Group 1 (n=10: salvage radical prostatectomy (sRP with SePLND (salvage extended pelvic lymph nodes dissection (initial treatment: combined brachytherapy. Group 2 (n=22: SePLND (initial treatment: radical prostatectomy (RP. Group 3 (n=9: SePLND (initial treatment: RP and adjuvant radiation therapy (RT. We observed PSA, PSA-velocity, localization of LNs and LNs+, BCR-free period, and BR (biochemical response. Results. Group 1: 60% with BCR-freedom (mean 27.2 months. Group 2: 63.6% with BCR-freedom (mean 17.5 months. Group 3: 33.3% with BCR-freedom (mean 17.6 months. In total, BCR-freedom was observed in 23 of 41 patients (56.1% after salvage surgery. 75.6% of all patients showed a BR. 765 LNs were removed and 14.8% of these were LN+. Conclusions. The BCR-free period and BR are comparable in all three groups. Sensibility to ADT can be reestablished and prolonged as a result of SePLND. Multicenter studies are needed for a reliable output.

    Salvage palliative chemotherapy in metastatic colorectal cancer has been associated with significant improvement in survival. However, not all patients receive all available therapies. Travel burden can affect patient access and use of future therapy. The present study aims to determine relationship between travel distance (TD) and salvage palliative chemotherapy in patients with metastatic colorectal cancer. A patient cohort diagnosed with metastatic colorectal cancer during 2006-2010 in the province of Saskatchewan, Canada was studied. Logistic regression analyses were performed to assess relationship between travel distance and subsequent line therapies. The median age of 264 eligible patients was 62 years [interquartile range (IQR): 53-72]. The patients who received salvage systemic therapy had a median distance to travel of 60.0 km (IQR: 4.7-144) compared with 88.1 km (IQR: 4.8-189) if they did not receive second- or third-line therapy (P=0.06). In multivariate analysis distance to the cancer center therapies. Our result revealed that travel distance to the cancer center greater than 100 km was associated less frequent use of second or subsequent line therapies in patients with metastatic colorectal cancer.

    Nicotinamide adenine dinucleotide (NAD) is a crucial cofactor for the redox reactions in the metabolic pathways of cancer cells that have elevated aerobic glycolysis (Warburg effect). Cancer cells are reported to rely on NAD recycling and inhibition of the NAD salvage pathway causes metabolic collapse and cell death. However, the underlying regulatory mechanisms and clinical implications for the NAD salvage pathway in pancreatic ductal adenocarcinoma (PDAC) remain unclear. This study showed that the expression of Nampt, the rate-limiting enzyme of the NAD salvage pathway, was significantly increased in PDAC cells and PDAC tissues. Additionally, inhibition of Nampt impaired tumor growth in vitro and tumorigenesis in vivo, which was accompanied by a decreased cellular NAD level and glycolytic activity. Mechanistically, the Nampt expression was independent of Kras and p16 status, but it was directly regulated by miR-206, which was inversely correlated with the expression of Nampt in PDAC tissues. Importantly, pharmacological inhibition of Nampt by its inhibitor, FK866, significantly enhanced the antitumor activity of gemcitabine in PDAC cells and in orthotopic xenograft mouse models. In conclusion, the present study revealed a novel regulatory mechanism for Nampt in PDAC and suggested that Nampt inhibition may override gemcitabine resistance by decreasing the NAD level and suppressing glycolytic activity, warranting further clinical investigation for pancreatic cancer treatment.

  19. Septic Shock following Prostate Biopsy: Aggressive Limb Salvage for Extremities after Pressor-Induced Ischemic Gangrene

    Directory of Open Access Journals (Sweden)

    Jocelyn Lu, BS

    2017-09-01

    Full Text Available Summary:. Vasopressors used to treat patients with septic shock can cause ischemic necrosis of appendages such as the ears and nose, as well as the extremities. Cases of quadruple-extremity necrosis have high morbidity and mortality, and a profound negative impact on quality of life. This case report details the successful limb salvage and return to function using free tissue transfer as a means to salvage bilateral lower extremities in a patient who suffered vasopressor-induced ischemia of upper and lower extremities after prostate biopsy–induced septic shock. Septic shock following transrectal ultrasound–guided prostate biopsy is a rare, yet life-threatening complication. Successful treatment included thorough planning and staging of therapies such as awaiting tissue demarcation and serial surgical debridement to adequately prepare the tissue bed for free tissue transfer. Adjunctive treatments such as hyperbaric oxygen therapy, negative-pressure wound therapy, and meticulous wound care played a crucial role in wound healing. This vigilant planning and coordinated care resulted in the successful lower extremity salvage, consisting of bilateral transmetatarsal amputations and free tissue transfer to both limbs. We present our long-term follow-up of a functional ambulatory patient after catastrophic, life-threatening infection and appropriate multidisciplinary care.

    1988-01-01

    A retrospective analysis was performed of 118 surgically treated mammary recurrences, occurring following primary conservative excision and radiation therapy for clinical Stages I and II breast cancer. Actuarial cancer-specific survival following salvage surgery was 72% at 5 years and 58% at 10 years. With a median followup of 7 years, further local-regional recurrences were observed in 20 of the 118 patients, many of whom could be treated by further surgery. Actuarial survival after recurrence was significantly influenced by initial clinical stage, as well as by the disease-free interval following primary therapy, but was similar for both premenopausal and postmenopausal patients and for patients treated by radical or breast-conserving salvage operations. For recurrences after the fifth year, actuarial survival following salvage surgery was 83% and 68% at 5 and 10 years, respectively. Survival for Stage I patients was favorable regardless of disease-free interval. It is concluded that recurrences in the breast following primary treatment with limited surgery and irradiation have a considerably more favorable prognosis than that of local failures after primary radical surgery. Suggestions for the management of these recurrences are presented

  1. An ecosystem services approach to the ecological effects of salvage logging: valuation of seed dispersal.

    2017-06-01

    Forest disturbances diminish ecosystem services and boost disservices. Because post-disturbance management intends to recover the greatest possible value, selling timber often prevails over other considerations. Ecological research has shown diverse effects of salvage logging, yet such research has focused on the biophysical component of post-disturbance ecosystems and lacks the link with human well-being. Here we bridge that gap under the ecosystem services framework by assessing the impact of post-fire management on a non-timber value. By employing the replacement cost method, we calculated the value of the post-fire natural regeneration of Holm oaks in southern Spain under three post-fire management options by considering the cost of planting instead. The value of this ecosystem service in non-intervention areas doubled that of salvage-logged stands due to the preference for standing dead trees by the main seed disperser. Still, most of the value resulted from the resprouting capacity of oaks. The value of this and other ecosystem services should be added to traditional cost/benefit analyses of post-disturbance management. We thus call for a more holistic approach to salvage logging research, one that explicitly links ecological processes with human well-being through ecosystem services, to better inform decision-makers on the outcomes of post-disturbance management. © 2017 by the Ecological Society of America.

    The meninges composed of the dura, the arachnoid and the pia are significant sites of blood-brain barrier. Physical disruption of the integrity of the meninges from a variety of causes including surgery results in various patterns of meningeal enhancement on contrast enhanced MR images. It is important to distinguish normal reactive or benign postoperative enhancement from more serious leptomeningeal metastasis or infection, particularly in children with intracranial neoplasms. We present various patterns of meningeal enhancement on MRI in children following surgery for brain neoplasms. (author)

    Purpose: To compare the pre- and postoperative MR appearance of craniopharyngiomas with respect to lesion size, tumour morphology and identification of surrounding normal structures. Material and Methods: MR images obtained prior to and following craniopharyngioma resection were evaluated retrospectively in 10 patients. Tumour signal charcteristics, size and extension with particular reference to the optic chiasm, the pituitary gland, the pituitary stalk and the third ventricle were evaluated. Results: Following surgery, tumour volume was reduced in all patients. In 6 patients there was further tumour volume reduction between the first and second postoperative images. Two of these patients received radiation therapy between the 2 postoperative studies, while 4 had no adjuvant treatment to the surgical intervention. There was improved visualization of the optic chiasm, in 3, the pituitary stalk in one, and the third ventricle in 9 of the 10 patients. The pituitary gland was identified preoperatively only in one patient, postoperatively only in another, pre- and postoperatively in 5, and neither pre- nor postoperatively in 3 patients. In 3 patients MR imaging 0-7 days postoperatively identified tumour remnants not seen at the end of the surgical procedure. The signal intensities of solid and cystic tumour components were stable from pre- to the first postoperative MR images. Optic tract increased signal prior to surgery was gone 28 days postoperatively in one patient, but persisted on the left side for 197 days after surgery in another. Conclusion: Postoperative MR imaging of craniopharyngiomas demonstrated tumour volume reduction and tumour remnants not seen at surgery. Early postoperative MR imaging of craniopharyngiomas may overestimate the size of residual tumour. Improved visualization of peritumoral structures may be achieved. (orig.).

The correlation between the blood loss volume and postoperative VAS with the gender, age, and operating time was assessed using the t-test and Spearman rank correlation coefficient. The correlation between the magnitude of mandibular setback with the presence of TMJ clicking symptoms and lip sensation was also assessed. Results. The mean operating time and blood loss volume for men and women were 249.52 min and 229.39 min, and 104.03 mL and 86.12 mL, respectively. The mean VAS in men and women was 3.21 and 2.93, and 1.79 and 1.32 on the first and second postoperative days. There is no gender difference in the operating time, blood loss, VAS, TMJ symptoms, and lip numbness. The magnitude of mandibular setback was not correlated with immediate and long-term postoperative lip numbness. Conclusion. There are no gender differences in the intraoperative hemorrhage and postoperative sequelae (pain, lip numbness, and TMJ symptoms). In addition, neither symptom was significantly correlated with the amount of mandibular setback. PMID:26543855

    Endoscopic and interventional techniques are currently the mainstay of management of bleeding duodenal ulcer. As well, for patients with perforated duodenal ulcer, laparoscopic simple closure is nowadays usually performed. Although indications for emergency antroduodenectomy have declined, this procedure is still necessary as a salvage option when conservative management has failed or is not practicable. Our study aimed to evaluate indications and results of antroduodenectomy with gastroduodenal anastomosis in current practice and to examine the factors that predict operative outcomes. All patients who underwent emergency antroduodenectomy with gastroduodenal anastomosis in two surgical care departments specialized in emergency digestive surgery were studied from 2000 to 2015. Thirty-five patients (27 males, 77 %) with a median age of 68 years (20-90) underwent emergency antroduodenectomy with gastroduodenal anastomosis. Indications were bleeding and perforated duodenal ulcer in 24 and 11 patients, respectively. The overall complication rate was 69 %, especially because of a high rate of medical complications (57 %). Only two patients (6 %) required reoperation for anastomotic leakage. The overall mortality rate was 40 % (n = 14). According to the univariate analysis, age >70, >3 comorbidities, ASA score >2, and postoperative medical complications were associated with an increased risk of in-hospital mortality. In the multivariate analysis, age and ASA score remained independent risk factors. No recurrence of complicated duodenal disease was observed. Antroduodenectomy with gastroduodenal anastomosis is a safe and effective long-term strategy, with a low and acceptable rate of surgical complications, for complicated duodenal ulcer not responding to conservative measures.

    The aim of the present retrospective study is to evaluate toxicity and early clinical outcomes of interstitial hyperthermia (IHT) combined with high-dose rate (HDR) brachytherapy as a salvage treatment in patients with biopsy-confirmed local recurrence of prostate cancer after previous external beam radiotherapy. Between September 2008 and March 2013, 25 patients with local recurrence of previously irradiated prostate cancer were treated. The main eligibility criteria for salvage prostate HDR brachytherapy combined with interstitial hyperthermia were biopsy confirmed local recurrence and absence of nodal and distant metastases. All patients were treated with a dose of 30 Gy in 3 fractions at 21-day intervals. We performed 62 hyperthermia procedures out of 75 planned (83 %). The aim of the hyperthermia treatment was to heat the prostate to 41-43 C for 60 min. Toxicity for the organs of the genitourinary system and rectum was assessed according to the Common Terminology Criteria for Adverse Events (CTCAE, v. 4.03). Determination of subsequent biochemical failure was based on the Phoenix definition (nadir + 2 ng/ml). The median age was 71 years (range 62-83 years), the median initial PSA level was 16.3 ng/ml (range 6.37-64 ng/ml), and the median salvage PSA level was 2.8 ng/ml (1.044-25.346 ng/ml). The median follow-up was 13 months (range 4-48 months). The combination of HDR brachytherapy and IHT was well tolerated. The most frequent complications were nocturia, weak urine stream, urinary frequency, hematuria, and urgency. Grade 2 rectal hemorrhage was observed in 1 patient. No grade 3 or higher complications were observed. The 2-year Kaplan-Meier estimate of biochemical control after salvage treatment was 74 %. The PSA in 20 patients decreased below the presalvage level, while 11 patients achieved a PSA nadir < 0.5 ng/ml. All patients are still alive. Of the 7 patients who experienced biochemical failure, bone metastases were found in 2 patients. IHT in combination

    Selection of patients for hepatectomy for hepatocellular carcinoma conventionally has been based upon Child-Pugh grading. However, postoperative liver failure after hepatectomy is a major cause of hospital mortality. A new predictor of postoperative liver failure is required. The objective of this study was to identify risk factors for postoperative liver failure after hepatectomy. Perioperative risk factors for liver failure after hepatectomy were analyzed in 112 patients with hepatocellular carcinoma Eight of these patients died of liver failure. Stepwise multivariate logistic regression was performed to investigate significant independent factors among 17 variables, including the serum alkaline phosphatase ratio (ALPR) on the first day after hepatectomy. ALPR was calculated as the postoperative ALP level divided by the ALP level before surgery. Significant risk factors of postoperative liver failure were ALPR on postoperative day 1 (ALPR1), sex, operative blood loss, and operative procedure. As an indicator of liver failure, the diagnostic accuracy of the ALPR1 was 93.7% when the ALPR was less than 0.4 on the first postoperative day. The ALPR and the serum total bilirubin concentration after hepatectomy were uncorrelated. ALPR1 is a useful predictor of liver failure after hepatectomy.

    Our aim was to assess whether magnetic resonance imaging (MRI) features predict recurrence-free survival (RFS) after prostate cancer high-intensity focused ultrasound (HIFU) ablation. We retrospectively selected 81 patients who underwent (i) whole-gland HIFU ablation between 2007 and 2011 as first-line therapy or salvage treatment after radiotherapy or brachytherapy, and (ii) pre- and postoperative MRI. On preoperative imaging, two senior (R1, R2) and one junior (R3) readers assessed the number of sectors invaded by the lesion with the highest Likert score (dominant lesion) using a 27-sector diagram. On postoperative imaging, readers assessed destruction of the dominant lesion using a three-level score. Multivariate analysis included the number of sectors invaded by the dominant lesion, its Likert and destruction scores, the pre-HIFU prostate-specific antigen (PSA) level, Gleason score, and the clinical setting (primary/salvage). The most significant predictor was the number of prostate sectors invaded by the dominant lesion for R2 and R3 (p≤0.001) and the destruction score of the dominant lesion for R1 (p = 0.011). The pre-HIFU PSA level was an independent predictor for R2 (p = 0.014), but with only marginal significance for R1 (p = 0.059) and R3 (p = 0.053). The dominant lesion's size and destruction assessed by MRI provide independent prognostic information compared with usual predictors. (orig.)

  16. Surgical correction of postoperative astigmatism

    Full Text Available The photokeratoscope has increased the understanding of the aspheric nature of the cornea as well as a better understanding of normal corneal topography. This has significantly affected the development of newer and more predictable models of surgical astigmatic correction. Relaxing incisions effectively flatten the steeper meridian an equivalent amount as they steepen the flatter meridian. The net change in spherical equivalent is, therefore, negligible. Poor predictability is the major limitation of relaxing incisions. Wedge resection can correct large degrees of postkeratoplasty astigmatism, Resection of 0.10 mm of tissue results in approximately 2 diopters of astigmatic correction. Prolonged postoperative rehabilitation and induced irregular astigmatism are limitations of the procedure. Transverse incisions flatten the steeper meridian an equivalent amount as they steepen the flatter meridian. Semiradial incisions result in two times the amount of flattening in the meridian of the incision compared to the meridian 90 degrees away. Combination of transverse incisions with semiradial incisions describes the trapezoidal astigmatic keratotomy. This procedure may correct from 5.5 to 11.0 diopters dependent upon the age of the patient. The use of the surgical keratometer is helpful in assessing a proper endpoint during surgical correction of astigmatism.

    Salvage liver transplantation (LT) is considered a feasible option for the treatment of recurrent hepatocellular carcinoma (HCC). We performed this multicenter study to assess the risk factors associated with the recurrence of HCC and patient survival after salvage LT. Between January 2000 and December 2011, 101 patients who had previously undergone liver resection (LR) for HCC underwent LT at 3 transplant centers in Korea. Sixty-nine patients' data were retrospectively reviewed for the analysis. The recurrence of HCC was diagnosed at a median of 10.6 months after the initial LR, and patients underwent salvage LT. Recurrences were within the Milan criteria in 48 cases and were outside the Milan criteria in 21 cases. After salvage LT, 31 patients had HCC recurrence during a median follow-up period of 24.5 months. There were 24 deaths, and 20 were due to HCC recurrence. The 5-year overall survival rate was approximately 54.6%, and the 5-year recurrence-free survival rate was 49.3%. HCC recurrence within the 8 months after LR [hazard ratio (HR) = 3.124, P = 0.009], an alpha-fetoprotein level higher than 200 ng/mL (HR = 2.609, P = 0.02), and HCC outside the Milan criteria at salvage LT (HR = 2.219, P = 0.03) were independent risk factors for poor recurrence-free survival after salvage LT. In conclusion, the timing and extent of HCC recurrence after primary LR both play significant roles in the outcome of salvage LT. © 2014 American Association for the Study of Liver Diseases.

    Purpose: To describe long-term outcomes and toxicity after salvage brachytherapy (BT) for local failure after initial radiotherapy for prostate cancer. Methods and Materials: Between 1994 and 2008, 37 men with local failure after initial prostate radiotherapy (32 external-beam radiation therapy [EBRT] and 5 BT) underwent salvage BT with 103 Pd or 125 I. Estimates of freedom from biochemical failure (FFbF, Phoenix definition) and cause-specific survival (CSS) were calculated using the Kaplan-Meier method. Toxicities were graded using CTCv3.0. Results: Median follow-up was 86 months (range, 2-156). The median dose to 90% of the prostate volume was 122 Gy (range, 67-166). The 10-year FFbF and CSS were 54% and 96%, respectively. On univariate analysis, prostate-specific antigen (PSA) >10 ng/mL at initial diagnosis was significantly associated with FFbF (p = 0.01), and there were trends for both age <70 years (p = 0.08) and PSA <6 ng/mL (p = 0.08) at the time of salvage BT. On multivariate analysis, only presalvage PSA <6 ng/mL (p = 0.046) was significantly associated with improved FFbF. There were three Grade 3 toxicities and one Grade 4 toxicity. Pelvic lymph node dissection before salvage BT was the only variable significantly associated with Grade ≥2 toxicity (p = 0.03). Conclusion: With a median follow-up of 86 months, salvage prostate BT was associated with a 10-year FFbF of 54% and CSS of 96%. Improved FFbF was associated with a presalvage PSA <6 ng/mL. Toxicity was worse in patients who had undergone pelvic lymph node dissection before salvage BT. Careful patient selection for salvage BT may result in improved outcomes and reduced toxicity.

    An intense debate exists on the effects of post-fire salvage logging on plant community regeneration, but scant data are available derived from experimental studies. We analyzed the effects of salvage logging on plant community regeneration in terms of species richness, diversity, cover, and composition by experimentally managing a burnt forest on a Mediterranean mountain (Sierra Nevada, S Spain). In each of three plots located at different elevations, three replicates of three treatments were implemented seven months after the fire, differing in the degree of intervention: "Non-Intervention" (all trees left standing), "Partial Cut plus Lopping" (felling 90% of the trees, cutting the main branches, and leaving all the biomass in situ), and "Salvage Logging" (felling and piling the logs, and masticating the woody debris). Plant composition in each treatment was monitored two years after the fire in linear point transects. Post-fire salvage logging was associated with reduced species richness, Shannon diversity, and total plant cover. Moreover, salvaged sites hosted different species assemblages and 25% lower cover of seeder species (but equal cover of resprouters) compared to the other treatments. Cover of trees and shrubs was also lowest in Salvage Logging, which could suggest a potential slow-down of forest regeneration. Most of these results were consistent among the three plots despite plots hosting different plant communities. Concluding, our study suggests that salvage logging may reduce species richness and diversity, as well as the recruitment of woody species, which could delay the natural regeneration of the ecosystem.

  1. New insights into the consequences of post-windthrow salvage logging revealed by functional structure of saproxylic beetles assemblages.

    Directory of Open Access Journals (Sweden)

    Simon Thorn

    Full Text Available Windstorms, bark beetle outbreaks and fires are important natural disturbances in coniferous forests worldwide. Wind-thrown trees promote biodiversity and restoration within production forests, but also cause large economic losses due to bark beetle infestation and accelerated fungal decomposition. Such damaged trees are often removed by salvage logging, which leads to decreased biodiversity and thus increasingly evokes discussions between economists and ecologists about appropriate strategies. To reveal the reasons behind species loss after salvage logging, we used a functional approach based on four habitat-related ecological traits and focused on saproxylic beetles. We predicted that salvage logging would decrease functional diversity (measured as effect sizes of mean pairwise distances using null models as well as mean values of beetle body size, wood diameter niche and canopy cover niche, but would increase decay stage niche. As expected, salvage logging caused a decrease in species richness, but led to an increase in functional diversity by altering the species composition from habitat-filtered assemblages toward random assemblages. Even though salvage logging removes tree trunks, the most negative effects were found for small and heliophilous species and for species specialized on wood of small diameter. Our results suggested that salvage logging disrupts the natural assembly process on windthrown trees and that negative ecological impacts are caused more by microclimate alteration of the dead-wood objects than by loss of resource amount. These insights underline the power of functional approaches to detect ecosystem responses to anthropogenic disturbance and form a basis for management decisions in conservation. To mitigate negative effects on saproxylic beetle diversity after windthrows, we recommend preserving single windthrown trees or at least their tops with exposed branches during salvage logging.

    Evidence suggests that perioperative allogeneic blood transfusion increases the risk of infectious complications after major surgery and of cancer recurrence after curative operation. This has been attributed to immunosuppression. Several authors have suggested that filtered whole blood and/or red...... cell concentrate, or leucocyte- and buffy coat-reduced red cells in artificial medium or their own plasma, may reduce postoperative immunosuppression. It was also anticipated that the use of autologous blood might minimize the risk of perioperative transfusion, but studies have unexpectedly shown...... similar postoperative infectious complications and cancer recurrence and/or survival rates in patients receiving autologous blood donated before operation and those receiving allogeneic blood.

    Full Text Available ABSTRACT Purpose: To determine the predictive factors for postoperative urinary incontinence (UI following holmium laser enucleation of the prostate (HoLEP during the initial learning period. Patients and Methods: We evaluated 127 patients with benign prostatic hyperplasia who underwent HoLEP between January 2011 and December 2013. We recorded clinical variables, including blood loss, serum prostate-specific antigen levels, and the presence or absence of UI. Blood loss was estimated as a decline in postoperative hemoglobin levels. The predictive factors for postoperative UI were determined using a multivariable logistic regression analysis. Results: Postoperative UI occurred in 31 patients (24.4%, but it cured in 29 patients (93.5% after a mean duration of 12 weeks. Enucleation time >100 min (p=0.043 and blood loss >2.5g/dL (p=0.032 were identified as significant and independent risk factors for postoperative UI. Conclusions: Longer enucleation time and increased blood loss were independent predictors of postoperative UI in patients who underwent HoLEP during the initial learning period. Surgeons in training should take care to perform speedy enucleation maneuver with hemostasis.

    Cardiopulmonary bypass induces platelet activation and dysfunction, which result in platelet deposition and depletion. Reduced platelet numbers and abnormal platelet function may contribute to postoperative bleeding. A membrane oxygenator may preserve platelets and reduce bleeding more than a bubble oxygenator, and the antiplatelet agent dipyridamole may protect platelets intraoperatively and reduce bleeding postoperatively. A prospective randomized trial was performed in 44 patients undergoing elective coronary artery bypass grafting to assess the effects of the membrane oxygenator and dipyridamole on platelet counts, platelet activation products, and postoperative bleeding. Patients who were randomized to receive a bubble oxygenator and no dipyridamole had the lowest postoperative platelet counts, the greatest blood loss, and the most blood products transfused. Platelet counts were highest and blood loss was least in patients randomized to receive a membrane oxygenator and dipyridamole (p less than .05). A bubble oxygenator with dipyridamole and a membrane oxygenator without dipyridamole resulted in intermediate postoperative platelet counts and blood loss. Arterial thromboxane B2 and platelet factor 4 concentrations were elevated on cardiopulmonary bypass in all groups. Both the membrane oxygenator and dipyridamole were independently effective (by multivariate analysis) in preserving platelets. Optimal blood conservation was achieved with a membrane oxygenator and dipyridamole.

    2010-03-01

    In the last several years, there have been numerous advancements in the field of pulmonary hypertension as a whole, but there have been few changes in the management of children with pulmonary hypertension after cardiac surgery. Patients at particular risk for postoperative pulmonary hypertension can be identified preoperatively based on their cardiac disease and can be grouped into four broad categories based on the mechanisms responsible for pulmonary hypertension: 1) increased pulmonary vascular resistance; 2) increased pulmonary blood flow with normal pulmonary vascular resistance; 3) a combination of increased pulmonary vascular resistance and increased blood flow; and 4) increased pulmonary venous pressure. In this review of the immediate postoperative management of pulmonary hypertension, various strategies are discussed including medical therapies, monitoring, ventilatory strategies, and weaning from these supports. With early recognition of patients at particular risk for severe pulmonary hypertension, management strategies can be directed at preventing or minimizing hemodynamic instability and thereby prevent the development of ventricular dysfunction and a low output state.

There is potential for further optimization of candidate selection for salvage cryoablation with curative intent and nadir PSA achieved after whole-gland cryotherapy may provide additional prognostic value. The study shows that the most important prognostic factors of biochemical progression-free survival for patients who have undergone whole-gland salvage prostate cryotherapy are nadir PSA achieved after therapy and pre-therapy biopsy Gleason score. Based on these two prognostic variables, we have identified risk stratification groups (low, intermediate and high) which help predict the expected outcomes of salvage whole-gland prostate cryotherapy in a given patient. This risk stratification constitutes a useful clinical tool in defining which patients maybe best suited for this local salvage treatment method. To assess the prognostic variables predicting the risk of biochemical progression-free survival (bPFS) after salvage prostate whole-gland cryotherapy using the Phoenix definition of bPFS. A total of 132 patients underwent prostate whole-gland salvage cryotherapy with curative intent. No patient underwent neoadjuvant/adjuvant hormonal ablative therapy, and all had extended post-salvage prostate-specific antigen (PSA) follow-up data. Cox univariate and multivariate logistic regression analyses of potential predictors of bPFS were conducted. Kaplan-Meier analyses of bPFS was also performed. At a mean (range) follow-up of 4.3 (0.9-12.7) years, the median (range) post-cryotherapy nadir PSA achieved was 0.17 (0-33.9) ng/mL. On multivariate analysis, predictors of bPFS were nadir PSA post-cryotherapy and pre-salvage biopsy Gleason score (P 2.5 ng/mL or biopsy Gleason score ≥ 7, with

    Mannose for mammalian glycan biosynthesis can be imported directly from the medium, derived from glucose or salvaged from endogenous or external glycans. All pathways must generate mannose 6-phosphate, the activated form of mannose. Imported or salvaged mannose is directly phosphorylated by hexokinase, whereas fructose 6-phosphate from glucose is converted to mannose 6-phosphate by phosphomannose isomerase (PMI). Normally, PMI provides the majority of mannose for glycan synthesis. To assess the contribution of PMI-independent pathways, we used PMI-null fibroblasts to study N-glycosylation of DNase I, a highly sensitive indicator protein. In PMI-null cells, imported mannose and salvaged mannose make a significant contribution to N-glycosylation. When these cells were grown in mannose-free medium along with the mannosidase inhibitor, swainsonine, to block the salvage pathways, N-glycosylation of DNase I was almost completely eliminated. Adding approximately 13 microm mannose to the medium completely restored normal glycosylation. Treatment with bafilomycin A(1), an inhibitor of lysosomal acidification, also markedly reduced N-glycosylation of DNase I, but in this case only 8 microm mannose was required to restore full glycosylation, indicating that a nonlysosomal source of mannose made a significant contribution. Glycosylation levels were greatly also reduced in glycoconjugate-free medium, when endosomal membrane trafficking was blocked by expression of a mutant SKD1. From these data, we conclude that PMI-null cells can salvage mannose from both endogenous and external glycoconjugates via lysosomal and nonlysosomal degradation pathways.

    The aim of this article is twofold: (a) to present the principles and the indications of surgical treatment of middle ear pathologies; and (b) to review the imaging findings after middle ear surgery, including the normal postoperative aspects and imaging findings in patients presenting with unsatisfactory surgical results or with suspicion of postoperative complications. This review is intentionally restricted to the most common diseases involving the middle ear: chronic otitis media and otosclerosis. In these specific fields of interest, CT and MR imaging play a very important role in the postoperative follow-up and in the work-up of surgical failures and complications. (orig.)

    Surgical complication rates of salvage laryngectomy after chemoradiotherapy (CRT) have been reported to be high. Wound complications after salvage laryngectomy following concurrent chemoradiotherapy (CCRT) were analyzed. Eighty-six patients who had undergone total laryngectomy for laryngeal cancer at Hokkaido University Hospital between 1990 and 2006 were divided into three groups according to preoperative treatments received: total laryngectomy (TL) group (n=35) without radiotherapy (RT) or CCRT, RT-TL group (n=17) with RT alone, CRT-TL group (n=34) with low-dose CCRT. Major wound complications were defined as major pharyngocutaneous fistulas which caused inpatient care for more than eight weeks or which were closed by surgery, bleeding that required surgical reintervention, and wound infection or skin necrosis that caused inpatient care for more than eight weeks. Minor complications were self-limited, managed with local wound care, and did not prolong inpatient care for more than eight weeks. We also analyzed wound complications of larynx preservation surgery after CCRT. Overall wound complications, both major and minor, were observed in 26% of the TL group, 35% of the RT-TL group, and 47% of the CRT-TL group. Major wound complications were observed in 11%, 18%, and 29%, respectively. A considerable but not statistically significant increase in the incidence of overall and major wound complications was observed between the TL and CRT-TL groups (p=0.082 and 0.078, respectively). Pharyngocutaneous fistulas were the most common complication, occurring in 14/86 (16%) of patients. Patients who developed pharyngocutaneous fistulas after CCRT tended to require surgical reintervention and longer periods before the initiation of oral intake. Wound complications were observed in 2/3 (67%) of patients who had undergone larynx preservation surgery. High incidences of wound complications and poor wound recovery in patients undergoing salvage laryngectomy following CCRT should

    The aim of the study was to analyze early effects and toxicity of salvage high dose rate brachytherapy for local recurrences of adenocarcinoma of the prostate after external beam radiotherapy (EBRT). In MCS Memorial Institute of Oncology in Gliwice a research programme on salvage HDR brachytherapy for local recurrences of prostate cancer treated previously with EBRT has been ongoing since February 2008. The treatment consisted of 3 fractions of 10 Gy each given every 14 days. Maximal urethral doses were constrained to be ≤ 120% of the prescribed dose. Maximal bladder and rectum doses were constrained to be ≤ 70% of the prescribed dose. Fifteen eligible patients were treated and analyzed from February 2008. All patients completed the treatment without major complications. The most common early complications were: macroscopic haematuria, pain in lower part of the abdomen, and transient dysuria. During the first week after the procedure a transient increase in IPSS score was noticed. The Foley catheter was removed on day 2 to 5. No complications after spinal anaesthesia were observed. Acute toxicity according to EORTC/RTOG was low. For bladder EORTC/RTOG score ranged from 0 to 2. Only in two patients grade 1 toxicity for rectum was observed. The follow-up ranged from 3 to 9 months. In one patient grade 2 rectal toxicity was observed, and one had urethral stricture. Other patients did not have any other significant late toxicity of the treatment. Two patients developed bone metastases. Salvage brachytherapy for localized prostate cancer (3 × 10 Gy every 14 days) seems to be a safe and well tolerated procedure. A significant decline in prostate-specific antigen (PSA) level is seen in patients with hormone-responsive cancer. Long-term efficiency and toxicity of the procedure are yet to be established.

    Purpose: The management of isolated local recurrence of soft-tissue sarcoma is therapeutically complex, and functional conservative management is preferable to radical or amputative salvage surgery. This study reviews University of Florida experience using conservative resection and reirradiation to manage isolated local recurrences of soft-tissue sarcoma. Methods and Materials: Between 1976 and 2005, a total of 14 patients who underwent primary conservative resection and irradiation developed isolated local recurrence and were managed with salvage conservative resection and reirradiation. Of the patients treated, 3 had tumors of the distal extremity, 8 had tumors of the proximal extremity, and 3 had tumors of the trunk. At the time of recurrence, 64% of tumors were greater than 5 cm and 79% were high grade. In combination with gross total resection, 13 of 14 patients received external beam radiotherapy with or without brachytherapy, and 1 patient was treated with brachytherapy alone. Two patients received chemotherapy. Results: The median follow-up was 30 months, and no living patients were lost during follow-up. From retreatment, the 5-year actuarial overall survival, cause-specific survival, and local control rates were 40%, 40%, and 18% respectively. There was a 50% incidence of serious complication requiring either reoperation or leading to permanent functional impairment. Of the 14 patients, only 1 has remained disease free and without significant complications. No treatment factors, including achieving wide surgical margins or delivering higher radiation dosages, seemed to confer an advantage in local control. Conclusions: Salvage therapy for management of locally recurrent soft-tissue sarcoma is challenging, and the effects of reoperation and reirradiation can be severe

    Purpose: Despite results of randomized trials that support adjuvant radiation therapy (RT) after radical prostatectomy (RP) for prostate cancer with adverse pathologic features (APF), many clinicians favor selective use of salvage RT. This survey was conducted to evaluate the beliefs and practices of radiation oncologists (RO) and urologists (U) regarding RT after RP. Methods and Materials: We designed a Web-based survey of post-RP RT beliefs and policies. Survey invitations were e-mailed to a list of 926 RO and 591 U. APF were defined as extracapsular extension, seminal vesicle invasion, or positive surgical margin. Differences between U and RO in adjuvant RT recommendations were evaluated by comparative statistics. Multivariate analyses were performed to evaluate factors predictive of adjuvant RT recommendation. Results: Analyzable surveys were completed by 218 RO and 92 U (overallresponse rate, 20%). Adjuvant RT was recommended based on APF by 68% of respondents (78% RO, 44% U, p <0.001). U were less likely than RO to agree that adjuvant RT improves survival and/or biochemical control (p < 0.0001). PSA thresholds for salvage RT were higher among U than RO (p < 0.001). Predicted rates of erectile dysfunction due to RT were higher among U than RO (p <0.001). On multivariate analysis, respondent specialty was the only predictor of adjuvant RT recommendations. Conclusions: U are less likely than RO to recommend adjuvant RT. Future research efforts should focus on defining the toxicities of post-RP RT and on identifying the subgroups of patients who will benefit from adjuvant vs. selective salvage RT.

    The objective was to analyze the outcomes of the patients, who received salvage radiotherapy for incidentally discovered cervical cancer following simple hysterectomy, and to identify the influence of intracavitary radiotherapy on treatment outcomes. Data from 117 patients with occult cervical cancer who underwent simple hysterectomy followed by salvage radiotherapy from September 1979 to November 2010 were collected. All the patients received external beam radiotherapy with (n=45) or without (n=72) intracavitary radiotherapy. Local control, disease-free survival, overall survival and treatment-related toxicity were investigated. The median follow-up time was 75 months. The 5- and 10-year local control/disease-free survival/overall survival rates were 93/87/87% and 90/84/83%, respectively. Among 98 patients who had no residual disease and negative resection margin on surgical specimens, 32 (33%) received intracavitary radiotherapy and 66 (67%) did not. There were no differences in patient and tumor characteristics between patients treated with and without intracavitary radiotherapy. The 5-year local control rate for the non-intracavitary radiotherapy group was 93 versus 94% for the intracavitary radiotherapy group (P=0.564); the disease-free survival rate was 88 versus 94% (P=0.894); the overall survival rate was 95 versus 85% (P=0.106), respectively. Among all patients, there were 5% of Grade 3 or higher late toxicities. Patients with occult invasive cervical cancer discovered following simple hysterectomy could be treated safely and effectively with salvage radiotherapy. For patients with no residual disease and negative resection margin, intracavitary radiotherapy could be omitted. (author)

    With global warming, forest fires may be increasing in frequency, and post-fire salvage logging may become more common. The ecophysiological impacts of this practice on tree saplings remain poorly understood. In this study, we examined the physiological and morphological impacts of increased light intensity, due to post-fire salvage logging, on the conifer Pinus contorta (pine) and deciduous broadleaf Salix lucida (willow) tree and shrub species in the Crowsnest Pass region of southern Alberta. Photosynthetic gas-exchange and plant morphological measurements were taken throughout the summer of 2013 on approximately ten year-old saplings of both species. Neither species exhibited photoinhibition, but different strategies were observed to acclimate to increased light availability. Willow saplings were able to slightly elevate their light-saturated rate of net photosynthesis (Amax) when exposed to higher photosynthetic photon flux density (PPFD), thus increasing their growth rate. Willow also exhibited increased leaf inclination angles and leaf mass per unit area (LMA), to decrease light interception in the salvage-logged plot. By contrast, pine, which exhibited lower Amax and transpiration (E), but higher water-use efficiency (WUE = Amax/E) than willow, increased the rate at which electrons were moved through and away from the photosynthetic apparatus in order to avoid photoinhibition. Acclimation indices were higher in willow saplings, consistent with the hypothesis that species with short-lived foliage exhibit greater acclimation. LMA was higher in pine saplings growing in the logged plot, but whole-plant and branch-level morphological acclimation was limited and more consistent with a response to decreased competition in the logged plot, which had much lower stand density.

    Although treatment of mild peri-prosthetic infection in implant-based breast reconstruction results in high rates of resolution, successful management of severe peri-prosthetic infection remains a significant challenge. In this case series, a protocol utilizing a novel dressing - negative pressure wound therapy with instillation (NPWTi) - for the management of severe peri-prosthetic infection in breast reconstruction patients is described. This is an operative technique involving: (i) explantation of the breast prosthesis and application of the NPWTi dressing to the implant pocket; (ii) change of the NPWTi dressing; (iii) intraoperative fluid/tissue cultures; and (iv) reimplantation of the breast prosthesis when cultures yield no growth. This protocol was utilized in six cases of severe peri-prosthetic infection in five patients with immediate breast reconstruction for breast cancer or risk-reducing surgery. Cultures of fluid/tissue grew typical and/or unusual organisms. Only one case did not yield an organism. The hospital length of stay upon completion of the protocol ranged from 7-16 days (mean, 12 days). Successful implant salvage was achieved in five of six cases. The protocol was aborted in one case to allow for completion of adjuvant chemotherapy. Early findings from this case series suggest that in cases of severe peri-prosthetic infection this novel operative protocol may result in successful implant salvage for breast reconstruction patients. Further studies are needed to more fully elaborate the role of NPWTi to achieve implant salvage in challenging cases of peri-prosthetic infection. © 2015 Royal Australasian College of Surgeons.

    The radiation field for patients with postoperative head and neck squamous cell carcinoma is narrower in our institution than in Western countries to reduce late radiation related toxicities. This strategy is at a risk of loco-regional or distant metastasis. However, because patients are more closely checked than in Western countries by every 1 to 2 months intervals and it is supposed that regional recurrences are identified and salvage surgeries are performed more quickly. Therefore, it is considered that patient survival would not be compromised with this strategy. The aim of this study was to investigate the feasibility of this strategy retrospectively. Patients who underwent neck dissection with close or positive margin, extra-capsular spread (ECS), multiple regional lymph node metastasis, pT4, with or without primary tumor resection were treated with postoperative radiation therapy. The volume of radiation field, especially the coverage of prophylactic regional lymph node area, was discussed among head and neck surgeons and radiation oncologists taking into account the clinical factors including patient’s age, performance status, number of positive lymph nodes, size of metastatic lymph nodes, extension of primary tumor beyond the midline, and existence of ECS. Seventy-two patients were identified who were treated with postoperative radiation therapy for head and neck squamous cell carcinoma between November 2005 and December 2014. There were 20 patients with oropharynx, 19 with hypopharynx, 7 with larynx, 23 with oral cavity, and 3 with other sites. Thirty eight patients had their neck irradiated bilaterally and 34 unilaterally. Median follow-up period for patients without relapse was 20.7 months (5.1–100.7). Thirty two patients had disease relapse after treatment including 22 loco-regional recurrence and 14 distant metastases. Among 22 loco-regional recurrence, seven patients underwent salvage surgery and one of them was no relapse at the time of the

    We examine emotional reactions to changes to medical spaces of care, linked with past experiences. In this paper we draw on findings from a qualitative study of the transfer of psychiatric inpatient care from an old to a newly built facility. We show how the meanings attributed to 'therapeutic landscapes' from one׳s past can evoke emotions and memories, manifesting in ideas about nostalgia, solastalgia, salvage and abandonment, which can impinge on one׳s present therapeutic experience. We reflect on how consideration of these ideas might contribute to better future design of psychiatric inpatient facilities and the wellbeing of those using them. Copyright © 2015 Elsevier Ltd.

    Full Text Available We report renal salvage maneuvers after accidental bilateral renal artery coverage during endovascular aneurysm repair of an infrarenal abdominal aortic aneurysm. A 79-year-old man with an infrarenal abdominal aortic aneurysm was treated with endovascular aneurysm repair. Completion angiography demonstrated coverage of the renal arteries. Several revascularization techniques were attempted, including endograft repositioning and endovascular stenting through the femoral and brachial approach. The patient eventually underwent open splenorenal bypass with a Y Gore-Tex graft (W. L. Gore & Associates, Flagstaff, Ariz. After 3 months, computed tomography showed no evidence of endoleak and patent renal arteries. Renal function was well maintained, and the patient did not require dialysis.

  7. Hyperthermophilic Archaeon Thermococcus kodakarensis Utilizes a Four-Step Pathway for NAD+ Salvage through Nicotinamide Deamination.

    2018-06-01

    Many organisms possess pathways that regenerate NAD + from its degradation products, and two pathways are known to salvage NAD + from nicotinamide (Nm). One is a four-step pathway that proceeds through deamination of Nm to nicotinic acid (Na) by Nm deamidase and phosphoribosylation to nicotinic acid mononucleotide (NaMN), followed by adenylylation and amidation. Another is a two-step pathway that does not involve deamination and directly proceeds with the phosphoribosylation of Nm to nicotinamide mononucleotide (NMN), followed by adenylylation. Judging from genome sequence data, the hyperthermophilic archaeon Thermococcus kodakarensis is supposed to utilize the four-step pathway, but the fact that the adenylyltransferase encoded by TK0067 recognizes both NMN and NaMN also raises the possibility of a two-step salvage mechanism. Here, we examined the substrate specificity of the recombinant TK1676 protein, annotated as nicotinic acid phosphoribosyltransferase. The TK1676 protein displayed significant activity toward Na and phosphoribosyl pyrophosphate (PRPP) and only trace activity with Nm and PRPP. We further performed genetic analyses on TK0218 (quinolinic acid phosphoribosyltransferase) and TK1650 (Nm deamidase), involved in de novo biosynthesis and four-step salvage of NAD + , respectively. The ΔTK0218 mutant cells displayed growth defects in a minimal synthetic medium, but growth was fully restored with the addition of Na or Nm. The ΔTK0218 ΔTK1650 mutant cells did not display growth in the minimal medium, and growth was restored with the addition of Na but not Nm. The enzymatic and genetic analyses strongly suggest that NAD + salvage in T. kodakarensis requires deamination of Nm and proceeds through the four-step pathway. IMPORTANCE Hyperthermophiles must constantly deal with increased degradation rates of their biomolecules due to their high growth temperatures. Here, we identified the pathway that regenerates NAD + from nicotinamide (Nm) in the

    2004-01-01

    Objective: the aim of this study is to select the risk factors for local failure requiring salvage neurosurgery in patients with brain metastases treated with stereotactic radiosurgery in a single institution. Methods: the follow-up of 123 patients, with 255 brain metastases treated with radiosurgery at the Radiation Oncology Department of the Hospital Israelita Albert Einstein from July 1993 to August 2001, was retrospectively analyzed. The criteria for salvage neurosurgery were tumor volume enlargement, or tumor persistence leading to severe neurological symptoms, life threatening situation or critical steroid dependence. We considered the case as local failure when the histopathologic evaluation showed morphologically preserved cancer cells (tumor recurrence, persistence or progression). We applied the Fisher's exact test to evaluate the statistical correlation between local failure and primary tumor histology, volume of the brain metastases, prescribed radiosurgery dose, and whole brain radiotherapy. Results: fourteen of 123 patients (11%) underwent salvage neurosurgery. Histology showed preserved cancer cells with necrosis and/or bleeding in 11 cases (9% of the total accrual), and only necrosis with or without bleeding (without preserved cancer cells) in three cases. The primary tumor histology among the 11 patients considered with active neoplasia was malignant melanoma in five cases (21% of the patients with melanoma), breast adenocarcinoma in three (16% of the patients with breast cancer), and other histology in the remaining three. Breast cancer diagnosis, non-elective whole brain irradiation, volume of the brain metastases, and the prescribed radiosurgery dose did not correlate with the risk of local failure. Patients treated with elective whole brain radiotherapy showed fewer local failures, when compared to all patients receiving whole brain radiotherapy, and to the patients not receiving this treatment, with incidence of failure in 4%,7% and 14

    2007-12-15

    Multimodality imaging of the postoperative shoulder includes radiography, magnetic resonance (MR) imaging, MR arthrography, computed tomography (CT), CT arthrography, and ultrasound. Target-oriented evaluation of the postoperative shoulder necessitates familiarity with surgical techniques, their typical complications and sources of failure, knowledge of normal and abnormal postoperative findings, awareness of the advantages and weaknesses with the different radiologic techniques, and clinical information on current symptoms and function. This article reviews the most commonly used surgical procedures for treatment of anterior glenohumeral instability, lesions of the labral-bicipital complex, subacromial impingement, and rotator cuff lesions and highlights the significance of imaging findings with a view to detection of recurrent lesions and postoperative complications in a multimodality approach.

    Preoperative, immediate postoperative, and delayed (2-6 months) postoperative MR studies were obtained in 20 patients who had undergone a variety of spinal surgical procedures. In addition, 50 postoperative patients without preoperative studies were also reviewed. MR studies included sagittal T1-weighted, T2-weighted, and axial T1-weighted and multiecho T2-weighted images. The evolution of signal intensity changes with time is demonstrated. Diskectomy produced no significant vertebral body changes and reduced but did not completely remove the extradural mass of herniation. Anterior fusion resulted in decreased signal on T1-weighted and increased signal on T2-weighted images in adjacent vertebral bodies, which were changes that were similar to those seen around bone grafts but distinct from the graft itself. Scar formation was better defined 2-3 months postoperatively

    Despite progress in surgical techniques and modern medical treatment, postoperative complications occur not infrequently and vary according to type of surgery, clinical setting, and time elapsed since surgery. In general, they can be divided into early and delayed complications. Delayed postoperative complications can be classified as specific and nonspecific. The common nonspecific delayed complications are incisional hernia and postoperative bowel obstruction. Bowel obstruction can be further categorized as obstruction related to benign or neoplastic etiology, the latter occurring in oncology patients in whom the primary surgery was related to an underlying abdominal neoplasm. Gossypiboma is another, fortunately rare, postoperative complication. Specific complications appear after specific operations and include the following: Splenosis - following splenectomy. Retained gallstones and spilled gallstones - following cholecystectomy, mainly laparoscopic. Dropped appendicolith and stump appendicitis - following appendectomy, mainly laparoscopic. Obturation obstruction by a bezoar - following gastric surgery. Afferent loop syndrome (ALS) - following Bilroth II gastrectomy. (author)

    This study aimed to investigate the effects of blood glucose, blood lipids and blood pressure control on recovery of patients with gastric cancer complicated with metabolic syndrome (MS) after radical gastrectomy. A total of 150 patients with gastric cancer, who were treated in Daqing Longnan Hospital from November, 2015 to May, 2017, were enrolled in this study. The patients were divided into the MS group (80 cases) and non-MS group (70 cases). Patients in the MS group were given corresponding drugs to control blood pressure, blood lipids and blood glucose, while patients in the non-MS group were not treated with those drugs. Patients in the MS group were divided into the normal and abnormal groups according to the levels of blood glucose, blood lipids and blood pressure. Moreover, occurrences of complications were compared between the normal and abnormal groups. Before surgery, blood glucose, blood lipids and blood pressure in the MS group were significantly higher than those in the non-MS group (pblood glucose, blood lipids and blood pressure of the MS group decreased significantly compared to those before operation (pblood glucose, 2 h postprandial blood glucose, glycosylated hemoglobin, total triglycerides (TGs), LDL, mean blood pressure and BMI (pblood glucose, blood lipids and blood pressure in patients with gastric cancer complicated with MS after radical gastrectomy can reduce the incidence of postoperative complications and promote postoperative recovery.

    Intraoperative cell salvage (CS) of shed blood during emergency surgical procedures provides an effective and cost-efficient resuscitation alternative to allogeneic blood transfusion, which is associated with increased morbidity and mortality in trauma patients. Retrospective matched cohort study. Level I trauma center. All adult trauma patients who underwent an emergency operation and received CS as part of their intraoperative resuscitation. The CS group was matched to a no-CS group for age, sex, Injury Severity Score, mechanism of injury, and operation performed. Amount and cost of allogeneic transfusion of packed red blood cells and plasma. The 47 patients in the CS group were similar to the 47 in the no-CS group for all matched variables. Patients in the CS group received an average of 819 mL of autologous CS blood. The CS group received fewer intraoperative (2 vs 4 U; P = .002) and total (4 vs 8 U; P blood cells. The CS group also received fewer total units of plasma (3 vs 5 U; P = .03). The cost of blood product transfusion (including the total cost of CS) was less in the CS group ($1616 vs $2584 per patient; P = .004). Intraoperative CS provides an effective and cost-efficient resuscitation strategy as an alternative to allogeneic blood transfusion in trauma patients undergoing emergency operative procedures.

    Cosmetic tourism is defined as patient mobility across borders, typically constituted by patients seeking cosmetic surgery at lower costs abroad. The most common procedures are abdominoplasty, fat grafting and breast augmentation. Very little is known about the complication rates after cosmetic tourism, and there is a paucity of evidence in all aspects of cosmetic tourism. In this review, we focus on post-operative complications i.e. post-operative infections, in particular with rare microorganisms such as mycobacteria.

    To reduce the furfural toxicity for biochemical production in E. coli, a new strategy was successfully applied by supplying NAD(P)H through the nicotine amide salvage pathway. To alleviate the toxicity, nicotinamide salvage pathway genes were overexpressed in recombinant, isobutanol-producing E. coli. Gene expression of pncB and nadE respectively showed increased tolerance to furfural among these pathways. The combined expression of pncB and nadE was the most effective in increasing the tolerance of the cells to toxic aldehydes. By comparing noxE- and fdh-harbouring strains, the form of NADH, rather than NAD + , was the major effector of furfural tolerance. Overall, this study is the application of the salvage pathway to isobutanol production in the presence of furfural, and this system seems to be applicable to alleviate furfural toxicity in the production of other biochemical.

    2016-01-01

    Given that the efficacy of employing angiosome-targeted angioplasty in the treatment of diabetic foot remains controversial, this study was conducted to examine its efficacy. We performed a systematic literature review and meta-analysis using core databases, extracting the treatment modality of angiosome-targeted angioplasty as the predictor variable, and limb salvage, wound healing, and revision rate as the outcome variables. We used the Newcastle-Ottawa Scale to assess the study quality, along with the Cochrane Risk of Bias Tool. We evaluated publication bias using a funnel plot. The search strategy identified 518 publications. After screening these, we selected four articles for review. The meta-analysis revealed that overall limb salvage and wound healing rates were significantly higher (Odds ratio = 2.209, 3.290, p = 0.001, pdiabetic foot was more effective than nonangiosome-targeted angioplasty with respect to wound healing and limb salvage.

    SSGCID protein crystals were salvaged and stored using the MPCS Plug Maker and CrystalCards when high-throughput traditional sitting-drop vapor diffusion initially failed. The MPCS Plug Maker is a microcapillary-based protein-crystallization system for generating diffraction-ready crystals from nanovolumes of protein. Crystallization screening using the Plug Maker was used as a salvage pathway for proteins that failed to crystallize during the initial observation period using the traditional sitting-drop vapor-diffusion method. Furthermore, the CrystalCards used to store the crystallization experiments set up by the Plug Maker are shown be a viable container for long-term storage of protein crystals without a discernable loss of diffraction quality with time. Use of the Plug Maker with SSGCID proteins is demonstrated to be an effective crystal-salvage and storage method

    Full Text Available Abstract Background With dwindling rates of postoperative mortality in perforated peptic ulcer that is attributable to H2-receptor blocker usage, there is a need to shift the focus towards the prevention of postoperative morbidity. Further, the simultaneous contribution of several putative clinical predictors to this postoperative morbidity is not fully appreciated. Our objective was to assess the predictors of the risk, rate and number of postoperative complications in surgically treated patients of perforated peptic ulcer. Methods In a prospective cohort study of 96 subjects presenting as perforated peptic ulcer and treated using Graham's omentoplatsy patch or gastrojejunostomy (with total truncal vagotomy, we assessed the association of clinical predictors with three domains of postoperative complications: the risk of developing a complication, the rate of developing the first complication and the risk of developing higher number of complications. We used multiple regression methods – logistic regression, Cox proportional hazards regression and Poisson regression, respectively – to examine the association of the predictors with these three domains. Results We observed that the risk of developing a postoperative complication was significantly influenced by the presence of a concomitant medical illness [odds ratio (OR = 8.9, p = 0.001], abdominal distension (3.8, 0.048 and a need of blood transfusion (OR = 8.2, p = 0.027. Using Poisson regression, it was observed that the risk for a higher number of complications was influenced by the same three factors [relative risk (RR = 2.6, p = 0.015; RR = 4.6, p - blood group (RH = 4.7, p = 0.04. Conclusion Abdominal distension, presence of a concomitant medical illness and a history suggestive of shock at the time of admission warrant a closer and alacritous postoperative management in patients of perforated peptic ulcer.

    We have hypothesized that etoricoxib premedication would reduce the need for additional opioids following orthopedic trauma surgery. A double blind, controlled study, conducted in King Fahd University Hospital, King Faisal University, Dammam, Kingdom of Saudi Arabia. After obtaining the approval of Research and Ethics Committee and written consent, 200 American Society of Anesthesiology grade I and II patients that underwent elective upper limb or lower limb fracture fixation surgeries during the period from August 2005 to October 2007 were studied. Patients were randomly premedicated using 120 mg of etoricoxib or placebo n=100, each. To alleviate postoperative pain, a patient controlled analgesia device was programmed to deliver one mg of morphine intravenously locked lockout time, 6 minutes. Visual analog scale and total postoperative morphine consumption over 24 hours and the adverse effects were recorded. One hundred patients in each group completed the study period. Etoricoxib premedication provides a statistically significant postoperative morphine sparing effect over 24 hours postoperatively. Total morphine consumption was 44.2 (8.2) in the placebo and 35.17 mg in the etoricoxib groups p<0.001. The incidence of nausea and vomiting requiring treatment was lower in the etoricoxib group. p=0.014. The postoperative blood loss was similar in both groups. Etoricoxib is a suitable premedication before traumatic orthopedic surgery as it enhanced postoperative analgesia and reduced the need for morphine. (author)

    2006-01-01

    Purpose: The aim of this study was to evaluate efficacy of gynecologic examination under general anesthesia with cervical biopsies after (chemo) radiation for cervical cancer to identify patients with residual disease who may benefit from salvage surgery. Methods and Materials: In a retrospective cohort study data of all cervical cancer patients with the International Federation of Gynecology and Obstetrics (FIGO) Stage IB1 to IVA treated with (chemo) radiation between 1994 and 2001 were analyzed. Patients underwent gynecologic examination under anesthesia 8 to 10 weeks after completion of treatment. Cervical biopsy samples were taken from patients judged to be operable. In case of residual cancer, salvage surgery was performed. Results: Between 1994 and 2001, 169 consecutive cervical cancer patients received primary (chemo) radiation, of whom 4 were lost to follow-up. Median age was 56 years (interquartile range [IQR], 44-71) and median follow-up was 3.5 years (IQR, 1.5-5.9). In each of 111 patients a biopsy sample was taken, of which 90 (81%) showed no residual tumor. Vital tumor cells were found in 21 of 111 patients (19%). Salvage surgery was performed in 13 of 21 (62%) patients; of these patients, 5 (38%) achieved long-term, complete remission after salvage surgery (median follow-up, 5.2 years; range, 3.9-8.8 years). All patients with residual disease who did not undergo operation (8/21) died of progressive disease. Locoregional control was more often obtained in patients who underwent operation (7 of 13) than in patients who were not selected for salvage surgery (0 of 8 patients) (p < 0.05). Conclusions: Gynecologic examination under anesthesia 8 to 10 weeks after (chemo) radiation with cervical biopsies allows identification of those cervical cancer patients who have residual local disease, of whom a small but significant proportion may be salvaged by surgery

    2011-01-01

    The aim of this study was to investigate the efficacy and prognostic factors of salvage radiotherapy for prostate-specific antigen relapse after radical prostatectomy for prostate cancer at a single center in Japan. A retrospective review of the medical records of 51 patients who underwent salvage radiotherapy for prostate-specific antigen relapse after radical prostatectomy was carried out. Salvage radiotherapy was undergone for the single indication of at least two consecutive prostate-specific antigen elevations >0.1 ng/ml. Salvage radiotherapy was delivered to the prostatic bed at a total dose of 60 or 64 Gy. Late toxicity was scored according to the Common Terminology Criteria for Adverse Events 3.0. A total dose of 60 and 64 Gy were administered to 26 and 25 patients, respectively. The median prostate-specific antigen level at the initiation of radiotherapy was 0.29 ng/ml (range, 0.11-1.10 ng/ml). With a median follow-up of 57.3 months (range, 9.9-134.0 months), the prostate-specific antigen relapse-free rate at 5 years was 50.7%. Multivariate analysis using Cox's proportional hazards regression model revealed that the Gleason score at radical prostatectomy ≥8 significantly predicted prostate-specific antigen relapse after salvage radiotherapy (hazard ratio 4.531; 95% confidence interval 1.413-14.535; P=0.011). The prostate-specific antigen relapse-free rate at 5 years in the Gleason score at radical prostatectomy ≤7 and at radical prostatectomy ≥8 was 62.7 and 15.4%, respectively. Salvage radiotherapy was effective for prostate-specific antigen relapse after radical prostatectomy with tolerable toxicities in Japanese patients. A high Gleason score seemed to be a poor prognostic factor. (author)

    Although liberal blood transfusion thresholds have not been beneficial following noncardiac surgery, it is unclear whether higher thresholds are appropriate for patients who develop postoperative myocardial infarction (MI). To evaluate the association between postoperative blood transfusion and mortality in patients with coronary artery disease and postoperative MI following noncardiac surgery. Retrospective cohort study involving Veterans Affairs facilities from January 1, 2000, to December 31, 2012. A total of 7361 patients with coronary artery disease who underwent inpatient noncardiac surgery and had a nadir postoperative hematocrit between 20% and 30%. Patients with significant bleeding, including any preoperative blood transfusion or transfusion of greater than 4 units during the intraoperative or postoperative setting, were excluded. Mortality rates were compared using both logistic regression and propensity score matching. Patients were stratified by postoperative nadir hematocrit and the presence of postoperative MI. Initial postoperative blood transfusion. The 30-day postoperative mortality rate. Of the 7361 patients, 2027 patients (27.5%) received at least 1 postoperative blood transfusion. Postoperative mortality occurred in 267 (3.6%), and MI occurred in 271 (3.7%). Among the 5334 patients without postoperative blood transfusion, lower nadir hematocrit was associated with an increased risk for mortality (hematocrit of 20% to blood transfusion was associated with lower mortality, for those with hematocrit of 20% to 24% (odds ratio, 0.28; 95% CI, 0.13-0.64). In patients without postoperative MI, transfusion was associated with significantly higher mortality for those with hematocrit of 27% to 30% (odds ratio, 3.21; 95% C
