Selected AbstractsA retrospective review of chronic anal fistulae treated by anal fistulae plugCOLORECTAL DISEASE, Issue 5 2010G. El-Gazzaz Abstract Objective, The aim of this study was to analyse the efficacy of the anal fistulae plug (Cook Surgisis® AFPÔ) for the management of complex anal fistulae. Method, A review of patients with anal fistulae treated using Cook Surgisis® AFPÔ between October 2005 and 2007 was undertaken. Patient's demographics, fistulae aetiology and success rates were recorded. Results, Thirty-three patients underwent 49 plug insertions. The median age was 44.4 years; 18 females. The fistulae aetiology was cryptoglandular in 61% and Crohn's disease in 39%. The median follow up 221.5 days (range 44,684). Twenty-one patients had previous failed surgery. Twenty-eight patients had draining setons in situ at time of plug placement. The overall success rate was 8/32 patients (25%). Two of the 22 Crohn's fistulae healed (9.1%) and 9/26(34.6%) cryptoglandular fistulae healed. The reasons for failure were sepsis in 87% and plug dislodgement in 13%. Significant predictor factors for improved outcome were African-Americans patients (P = 0.009), and presence of seton (P = 0.05). Conclusions, Anal fistulae plug was associated with a lower success rate than previously reported. Septic complications were the main reason for failure.

To clarify the involvement of aberrant cytokine production and hepatocyte apoptosis in impaired resistance to bacterial infection in obstructive cholestasis, C57BL/6 mice or Fas-mutated lpr mice were inoculated intraperitoneally with 107 colony-forming units of Escherichia coli 5 days after bile duct ligation (BDL) or sham celiotomy. Cytokine levels in sera, liver, and immune cells were assessed via enzyme-linked immunosorbent assay or real-time reverse-transcriptase polymerase chain reaction. BDL mice showed delayed clearance of E. coli in peritoneal cavity, liver, and spleen. Significantly higher levels of serum interleukin (IL) 10 with lower levels of IL-12p40 were observed in BDL mice following E. coli infection. Interferon , production from liver lymphocytes in BDL mice was not increased after E. coli infection either at the transcriptional or protein level. Kupffer cells from BDL mice produced low levels of IL-12p40 and high levels of IL-10 in vitro in response to lipopolysaccharide derived from E. coli. In vivo administration of anti,IL-10 monoclonal antibody ameliorated the course of E. coli infection in BDL mice. Furthermore, BDL- lpr mice did not exhibit impairment in E. coli killing in association with little hepatic injury and a small amount of IL-10 production. In conclusion, increased IL-10 and reciprocally suppressed IL-12 production by Kupffer cells are responsible for deteriorated resistance to bacterial infection in BDL mice. Fas-mediated hepatocyte apoptosis in cholestasis may be involved in the predominant IL-10 production by Kupffer cells. (HEPATOLOGY 2004;40:414,423.) [source] Treatment of late-stage Sézary syndrome with 2-ChlorodeoxyadenosineINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 6 2002Saskia A. Bouwhuis MD Background, 2-Chlorodeoxyadenosine (2-CdA), a purine adenosine analog, is safe and effective chemotherapy for patients with hairy cell leukemia and low-grade lymphomas. Adverse effects include neutropenia, lymphocytopenia, and infectious complications. Our objective was to evaluate the efficacy of 2-CdA (2,6 seven-day cycles) in the treatment of late-stage, recalcitrant Sézary syndrome. Methods, Retrospective review of medical records of six patients with Sézary syndrome who had received 2-CdA cycles at Mayo Clinic, Rochester between March 1995 and March 2000. Variables assessed from the records included improvement in global appearance, extent of erythroderma, size of lymph nodes, pruritus, and leukocyte, lymphocyte, and absolute Sézary cell counts. Results, Two patients, both with stage III Sézary syndrome, whose previous treatment consisted of only two modalities, responded well to the treatment, with moderate to total clearing of erythroderma and pruritus associated with a significant decrease in Sézary cell counts. The other four patients had only a partial response (one patient) or no response (three patients) to 2-CdA. The mortality rate was 50%. All three patients died of Staphylococcus aureus sepsis. However, only one patient was receiving 2-CdA treatment when he died. The other two patients died 8 and 9 weeks after the last 2-CdA cycle. This high mortality rate is attributed to infectious complications after 2-CdA treatment in patients with recalcitrant disease. Conclusion, 2-Chlorodeoxyadenosine shows efficacy in stage III Sézary syndrome, but it also carries a substantial risk of septic complications and mortality. It can be used if no other suitable alternatives are available. Caution should be exercised in all these patients regarding skin care and avoidance of infections or sepsis. [source] Retrospective Evaluation of Partial Parenteral Nutrition in Dogs and CatsJOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 4 2002Daniel L. Chan The purpose of this retrospective study was to evaluate the use of partial parenteral nutrition (PPN) in dogs and cats. The medical records of all dogs and cats receiving PPN between 1994 and 1999 were reviewed to determine signalment, reasons for use of PPN, duration of PPN administration, duration of hospitalization, complications, and mortality. Complications were classified as metabolic, mechanical, or septic. One hundred twenty-seven animals (80 dogs and 47 cats) were included in the study, accounting for 443 patient days of PPN. The most common underlying diseases were pancreatitis (n = 41), gastrointestinal disease (n = 33), and hepatic disease (n = 23). Median time of hospitalization before initiation of PPN was 2.8 days (range, 0.2,10.7 days). Median duration of PPN administration was 3.0 days (range, 0.3,8.8 days). Median duration of hospitalization was 7 days (range, 2,20 days). In the 127 animals receiving PPN, 72 complications occurred. These included metabolic (n = 43), mechanical (n = 25), and septic (n = 4) complications. The most common metabolic complication was hyperglycemia (n = 19), followed by lipemia (n = 17) and hyperbilirubinemia (n = 6). Most complications were mild and did not require discontinuation of PPN. Ninety-three (73.2%) of the 127 patients were discharged. All 4 animals with septic complications were discharged from the hospital. The presence, type, and number of complications did not impact the duration of hospitalization or outcome. However, animals that received supplemental enteral nutrition survived more often than those receiving PPN exclusively. Although PPN seems to be a relatively safe method of providing nutritional support, future studies are warranted to determine its efficacy. [source] Small-for-size liver syndrome after auxiliary and split liver transplantation: Donor selectionLIVER TRANSPLANTATION, Issue 9 2003Nigel Heaton Small-for-size liver grafts can be defined by a recognizable clinical syndrome that results from the transplantation of too small a functional mass of liver for a designated recipient. A graft to recipient body weight ratio less than 0.8, impaired venous inflow, and enhanced metabolic demands in patients with poor clinical conditions must be considered as main factors leading to the small-for-size syndrome (SFSS) when using living and cadaveric partial grafts such as split and auxiliary liver grafts. Increased risk of graft dysfunction is currently observed in fatty infiltration of more than 30%, abnormal liver test results (especially bilirubin and gamma glutaryl transferase), and other donor risk factors such as high inotrope administration and donor stay in the intensive care unit (>5 days). Older donors are especially vulnerable to prolonged cold ischemia and high inotrope levels, giving rise to early graft dysfunction and prolonged cholestasis. Increased metabolic need on a functionally small-for-size graft predisposes to surgical and septic complications and poorer survival. Splitting livers into right and left lobe grafts increases the potential risk of small-for-size grafts for both recipients. Several techniques of venous outflow reconstruction/implantation have been proposed to reduce the risk of obstruction postoperatively. Prevention and management of SFSS will improve in parallel with the increased experience, allowing us optimum usage of available organs and reducing overall morbidity and mortality. (Liver Transpl 2003;9:S26-S28.) [source] Viral reactivation is not related to septic complications after major surgical resections,APMIS, Issue 4 2008T. VOGEL Anastomotic leakage and septic complications are the most important determinants of postoperative outcome after major surgical resections. Malignant diseases and surgical trauma can influence immune responses and the ability to react against infectious factors, such as bacteria and viruses. Comparable immune suppression can cause viral reactivation in transplantation and trauma patients. In this prospective study, patients who underwent major surgical resections for oesophageal or pancreatic cancer were investigated for the potential involvement of viral reactivation in the development of septic complications. 86 patients (40 oesophageal resections, 27 pancreatic resections, 19 surgical explorations) were included. Viral antigens, viral DNA, antibodies against viral structures (IgG, IgM, IgA) and, in part, viral cultivation were performed for CMV, EBV, HSV1, HSV2, HZV6 and VZV in serum, urine, sputum and swabs from buccal mucosa preoperatively and at postoperative days 1, 3 and 5. Test results were compared with the postoperative outcome (30-day morbidity, in-hospital mortality) and clinical scores (SOFA, TISS). For statistical analyses Student's t -tests and Chi2 -tests were used. The overall complication rate was 19.8% (30-day morbidity) with an in-hospital mortality of 1.2% (1/86 patients). Postoperatively, anti-CMV-IgG titres were significantly reduced (p<0.05) and remained suppressed in patients with septic complications. Anti-CMV-gB-IgG were also reduced, but showed considerable interindividual differences. Anti-CMV-IgA and -IgM did not show significant alterations in the postoperative course. In addition, direct viral detection methods did not support viral reactivation in patients in any of the investigated groups. The reduction of anti-CMV antibodies is likely caused by an immune suppression, specifically by reduced B-cell counts after major surgical interventions. Viral reactivation, however, did not occur in the early postoperative period as a specific risk for septic complications. [source] | ||||||||||
