ABSTRACT
Difficult-to-treat infections in surgical patients, such as serious skin and soft tissue infections (SSTIs) and complicated intra-abdominal infections (cIAIs), are the cause of significant morbidity and mortality, and carry an economic burden. These surgical site infections are typically polymicrobial infections caused by a plethora of pathogens, which include difficult-to-treat organisms and multiresistant Gram-positive and Gram-negative strains. Optimal management of SSTIs and cIAIs must take into account the presence of resistant pathogens, and depends on the administration of appropriate antimicrobial therapy (i.e. the correct spectrum, route and dose in a timely fashion for a sufficient duration as well as the timely implementation of source control measures). Treatment recommendations from the Infectious Diseases Society of America and the Surgical Infection Society are available for guidance in the management of both of these infections, yet the increased global prevalence of multidrug-resistant pathogens has complicated the antibiotic selection process. Several pathogens of concern include methicillin-resistant Staphylococcus aureus, responsible for problematic postoperative infections, especially in patients with SSTIs, extended-spectrum beta-lactamase-producing Gram-negative bacteria, including CTX-M-type-producing Escherichia coli strains, and multidrug-resistant strains of Bacteroides fragilis. New empirical regimens, taking advantage of potent broad-spectrum antibiotic options, may be needed for the treatment of certain high-risk patients with surgical site infections.

BACKGROUND: Case description of a patient who developed erysipelas of the surgical wound following appendectomy for acute appendicitis, and literature review of invasive group B streptococcal infections. METHODS: A 65-year-old man with perforated appendicitis underwent urgent appendectomy and drainage. Antibiotic prophylaxis with tobramycin (100 mg) and metronidazole (500 mg) was administered. At surgery, a phlegmon was identified with free perforation of the appendix and purulent peritoneal fluid. Appendectomy, irrigation with 0.9% NaCl solution, and drainage with a Silastic closed-suction drain was performed. A literature search in all languages was performed using MEDLINE, using the search terms surgical site infection, wound infection, group B streptococcus, Streptococcus agalactiae, necrotizing fasciitis, and postoperative infection. RESULTS: Erysipelas of the surgical wound developed on the fourth postoperative day. Intravenous penicillin and amoxicillin/clavulanic acid were administered empirically. Culture of the wound drainage identified Streptococcus agalactiae and a few colonies of Escherichia coli. The broad-spectrum antibiotic was discontinued, and a 10-day course of penicillin was completed. CONCLUSIONS: Erysipelas of the surgical wound is unusual, and infection with group B streptococci is rare compared with infection by group A streptococci. Streptococcus agalactiae is recognized to be increasingly virulent, with an increasing predilection for bacteremic infections in healthy hosts. Although Streptococcus agalactiae remains highly susceptible to antimicrobial agents effective against gram-positive cocci, the changing epidemiology and potentially invasive nature of these infections should have clinicians alert to the possibility of infection caused by group B streptococci.

OBJECTIVE: To assess the ability of clinical or biochemical parameters to predict outcome (survival or non-survival; severe or moderate/no complication) using multiple regression analyses. DESIGN: Prospective, descriptive cohort study with no interventions SETTING: 12 surgical intensive care units of university hospitals and large community hospitals; four medical school research laboratories in eight European countries PATIENTS: 128 surgical patients with major intra-abdominal surgery admitted for at least two days to an intensive care unit MAIN OUTCOME MEASURES: Prediction of complications or survival based on analysis of clinical (Multiple Organ Dysfunction Score, Multi-Organ-Failure Score, Acute Physiology and Chronic Health Evaluation II scores) and immunological (plasma levels of endotoxin, endotoxin neutralizing capacity, IL-6, IL-8, cell associated IL-8, Fc-receptor polymorphism, soluble CD-14) parameters, with comparison of predicted and actual outcomes. RESULTS: APACHE II, MODS score, MOF score, platelets, IL-6, IL-8, ENC, cell ass. IL-8 were significantly different between survivors and non-survivors and patients with/without severe complications by univariate analysis. By multivariate analysis only MOF, MODS score, IL-6, platelets, comorbidity predicted complications with a sensitivity of 82% and a specificity of 87%. Multivariate analysis demonstrated that only APACHE II score, plasma IL-8 and complications predicted death (sensitivity 84%; specificity 90%). CONCLUSION: Immunological surrogate parameters may predict complications and death of surgical ICU patients. The use of several parameters may add to increase sensitivity and specificity in a prognostic model.

BACKGROUND: The empiric antibiotic treatment of intraabdominal infections is in constant evolution. Monotherapy appears to be a desirable goal because of the simplicity of its administration, lack of toxic effects and wide spectrum. PATIENTS AND METHODS: A multicentre, prospective, randomized, open study was carried out to compare two antibiotic regimens in the treatment of intraabdominal infections in patients undergoing surgery. Ninety-eight consecutive patients were randomly allocated into two groups. One group (GM, n = 51) received meropenem (1 g/8 h) and the other (GCM, n = 47) a combination of cefotaxime (2 g/8 h) plus metronidazol (0.5 g/8 h). Clinical and bacteriological responses were assessed at the end of treatment and at 2-4 weeks. RESULTS: The severity of patients as assessed by the APACHE II score was similar in both groups (GM: 7.2 and GCM: 8.1). Three patients in each group could not be evaluated due to premature interruption of treatment or deviation from the protocol. The mean duration of treatment was 7.4 days in GM and 7.9 days in GCM. A satisfactory clinical response was obtained in 95% of patients in both groups. 31 patients (61%) in GM and 26 patients (55%) in GCM were bacteriologically evaluable. Bacteriological erradication was achieved in 94% of patients in GM and in 92% of patients in GCM. CONCLUSION: Meropenem is a good alternative for single antibiotic therapy in intraabdominal infections of moderate severity.

During the past 30 years, antibiotic prophylaxis has proved of enormous efficacy in reducing the incidence of surgical wound infections, postoperative morbidity and mortality, the duration of the postoperative period, and the overall cost of surgical treatment. In this paper, the timing and route of administration of antibiotic prophylaxis as well as the dosage and duration, the indications for antibiotic prophylaxis, the importance of the alterations of the delayed hypersensitivity response, and the value of antibiotic prophylaxis for prevention of postoperative septic complications in anergic patients are analyzed. The possibility of combining antibiotic prophylaxis with immunoprophylaxis for high-risk patients is also analyzed.

We report a prospective, controlled study of the incidence of septic complications following biliary tract stone surgery. This study included a total of 280 patients operated on in eight hospitals in various European countries. In this study the computer program "Surgery" was used. Of 280 patients, 77 (27.5%) were male and 203 (72.5%) were female. The age ranged from 20 to 92 years (mean 54.8 years); 78.9% of the cases corresponded to clean-contaminated surgery; 85% of the patients received antibiotic prophylaxis with cefazolin. Twenty-one patients developed postoperative septic complications (7.5%) of which 12 (4.3%) were wound infections; five patients (1.8%) had intra-abdominal infections. The wound infection rate was 3.2% in clean-contaminated surgery, 7.7% in contaminated and 20% in dirty (p < 0.02). In laparoscopic cholecystectomy the global rate of septic complications was 3.6% vs. 12.6% in open cholecystectomy (p < 0.01); 2.4% and 6.3% wound infection respectively. The mean age of patients who developed postoperative septic complications was 61.5 years and 54.2 years old who did not develop any complications (p < 0.03). The duration of the postoperative period was 5 days in patients without infection and 13 days in patients with infection (p < 0.0001). Two patients died, one of them (0.4%) caused by sepsis. In addition to the European prospective study, a review of the problems of sepsis in biliary surgery was carried out.

OBJECTIVE: To examine whether colostomy closure is an operation with a high risk of complications. DESIGN: Retrospective study of colostomy closures in a 14-year period. PARTICIPANTS: 60 patients, averaging 54 years, males in 63%. The main indication for colostomy was colorectal neoplasm (47%), followed by trauma (23%). RESULTS: There were 15 Hartman's procedure reconstructions, 4 reconstructions of colostomy and mucous fistula, and 41 "simple" colostomy closures. The closure was extraperitoneal in 40%, suturing only the anterior colonic wall in 42%. We had 27 postoperative complications in 33% of the patients, without mortality. The average hospital stay was 8 days longer in the group with complications. The complication rate was 29% in the "simple" closure versus 42% in the reconstruction group (this difference was not statistically significant). The statistic analysis (chi-square and Mann-Whitney tests) showed no influence on morbidity of factors such as age, sex, previous disease, age of colostomy, and type and closure technique of colostomy. CONCLUSIONS: Colostomy closure has a high rate of postoperative complications (33%). These are minor in almost all cases, without mortality.

With a view to creating national tables of the delayed hypersensitivity response, a total of 1476 healthy persons were studied at eight different locations in Spain. For the measurement of delayed cellular immunity response, Multitest IMC was used. Of those examined, 0.7% were anergic, 21.3 were relatively anergic, and 73 were immunocompetent. Of the 766 men, 28 were relatively anergic and 3 were anergic, whereas of the 710 women, 14 were relatively anergic (p < .001) and 8% were anergic (p < .001). The highest incidence of anergy was found in women of over 70 years (p < .001). Tuberculin was the antigen with the most positive responses, 77%, followed by Candida with 58%. Trichophyton and Proteus mirabilis were the antigens least recognized by the Spaniards studied. Major geographical variations were observed, both in the overall index for the delayed hypersensitivity response and in the response to different antigens. Catalonia revealed the highest level of anergy and the Valencia region, the lowest.

A prospective study of delayed hypersensitivity response was carried out in jaundiced patients. One hundred and seventy-seven subjects were studied. Fifty-nine were controls and one hundred and eighteen were patients with hepato-pancreato-biliary pathology and biliary tract obstruction. A multitest technique was used to evaluate the delayed hypersensitivity response, classifying the subjects into one of three groups: immunocompetent, relatively anergic and anergic. In the control group 76.3 per cent of the subjects were immunocompetent as opposed to 16.1 per cent of the patients (p less than 0.0001). Twenty-four per cent of the control subjects and eighty-four per cent of the patients presented anergy or relative anergy (p less than 0.0001). Among the patients no difference could be found in the index of anergy between malignant and benign pathology. We have found, moreover, that patients with a mean bilirubin level of 12 mg/dl showed a change in the delayed hypersensitivity response, with development of anergy or relative anergy.

This report comprises a study of splenic autotransplantation in omental pouches in rats. Twenty six rats were operated. The spleen (50%) was transplanted after splenectomy in four different fragments. The animals were re-explored after periods between 3 and 5 1/2 months and the splenic implants retrieved for histological examination as well as size and weight evolution. In 25/26 animals a viable spleen was identified. The mean weight of the retrieved spleen fragments was 150 mg versus 525 mg weight of the implanted materials. In no case there was an increase in size of the implanted fragments. Fifty-two of the 104 implanted fragments were retrieved with weight increase in 8.65% of them.
