Between April and September 1991, 415 injured patients were treated at the University Hospital Rebro, Zagreb, 362 at the Department of Surgery and 53 at the Department of Neurosurgery. Infections developed in 15.7% of the injured patients (wound infections in 14.6% and sepsis or meningitis in 1.1% of the injured patients). 88.2% of wound infections as well as all sepsis and meningitis were hospital-acquired infections, while 7.95 of wound infections occurred within 48 h of injuring. The major pathogens, in 90% of cases, were the aerobic bacteria (Enterobacteriaceae, Pseudomonas aeruginosa, Staphylococcus aureus, Acinetobacter species) while 9% of infections were caused by mixed aerobic-anaerobic flora. One injured patient developed clinical features of gas gangrene. Neither streptococcal wound infections nor tetanus were present in this group of the injured patients.

In 40 intensive care patients, tissue oxygen partial pressure distribution within skeletal muscle was measured in order to estimate peripheral oxygen availability. In septic patients with multiple organ failure (n = 20) mean skeletal muscle pO2 was abnormally high (48.8 +/- 8.5 mmHg, p less than 0.001) in contrast to patients with limited infection without sepsis (28.3 +/- 5.9 mmHg, n = 10). Mean muscle pO2 also discriminated between septic and cardiogenic shock (22.6 +/- 6.9 mmHg, p less than 0.001). The characteristic pattern of oxygen availability in septic patients--but not in patients with limited infection--was high skeletal muscle pO2 high whole body oxygen delivery and low whole body oxygen extraction, which was not influenced by the type of pathogenic agent of sepsis. In our patients in severe stage of sepsis, we did not observe local skeletal muscle hypoxia due to microcirculatory disorder. High mean skeletal muscle pO2 suggested reduced oxygen consumption within tissue rather than reduced oxygen transport to tissue in sepsis.

The authors report about 12 cases of long ureteral calculi, 16 to 39 mm in size, observed over 10 years. They were all made of a mixture of ammonium-magnesium phosphate and calcium phosphocarbonate. Infection was the revealing symptom, either in the form of simple bacteriuria or as acute pyelonephritis or sepsis. These calculi, found in a lumbar or pelvic location, were very long, radiopaque but with a moderate radiological density, homogeneous and have regular contours. They were straight, sometimes slightly bent, rarely (one case out of 12) arciform. In 11 of 12 cases, the affected patient was female. In most cases, the urine was infected by Proteus mirabilis. In spite of their size, the calculi caused total obstruction in 3 of 12 cases only. They were or were not associated to ipsilateral coral calculi of the same chemical type. Destruction was easily achieved with physical agents. The etiological, radiological and therapeutic characteristics of these calculi give them a specific place among ammonium-magnesium phosphate calculi.

High vaginal swabs (HVS) of 1792 expectant mothers were sent for culture at the time of delivery, prior to first vaginal examination. The newborns were followed-up for development of superficial or deep infections. Appropriate cultures of the babies who developed infections were sent. Bacterial growth of predominantly gram-ve organisms was obtained in 1026 (57%) HVS. Infection developed in 48 (27%) babies in 1st 72 hours of life, of which 28 had deep infection while the rest had superficial infection. Vertical transmission of organisms was documented in 24 (1.3%) mother-baby dyads and the same was 72% in newborns who were at risk of developing sepsis by septicemia scoring, showing a significantly higher incidence of vertical transmission and subsequent sepsis in high risk newborns.

A prospective randomized study was performed with 61 patients undergoing elective surgery for colorectal cancer, to evaluate the prophylactic effect of two different parenteral antibiotic regimens. All patients were randomly allocated into two groups, comparable in age, sex, nutritional status and operative procedures. The patients in Group A (n. 31) received 1 g i.v. of imipenem-cilastatin at induction of anesthesia. Patients in Group B (n. 30) were given cefuroxime (1.5 g i.v.) plus metronidazole (0.5 g i.v.) at the time of anesthesia and two other administrations of the combined antibiotics (cefuroxime 0.75 g plus metronidazole 0.5 g i.v.) every 8 hours. The severity of sepsis was evaluated according to the scoring system proposed by Elebute and Stoner. No significant differences were found in terms of the rate of surgical infections: 9% in Group A and 16% in Group B. Infections not of surgical origin were found only in Group B (10.4%). These data suggest that a single dose of intravenous imipenem-cilastatin appears to be as effective as three doses of cefuroxime and metronidazole as prophylaxis against infection in elective colorectal surgery.

Bacterial translocation (Bt) from the gastrointestinal (GI) tract to systemic organs creates the possibility of Infection and sepsis in a great number of pathologic entities. In a mouse model of Intestinal Obstruction (IO), we evaluated the type of micro-organisms and the organs that bacteria frequent translocated. At 24 hours post-10, positive cultures where obtained at the MLN, portal, systemic circulation and peritoneal cavity, establishing that the translocation is bi-directional. The more frequent bacteria isolated were the Streptococcus group D, Proteus mirabilis, Escherichia coli, Pseudomonas sp., an clostridium. BT occurs at 24 hour post-OI and was due to increased intestinal permeability, at 48 hrs BT increased and related to the physical disruption of the mucosal barrier in the intestinal mucosa. Cell mediated immunity (CMI) response in this model was not altered, although a progressive decrease was observed at 48 hrs it was not significant, suggesting that the CMI play no role in the pathogenesis of BT. In the Control-Laparotomy group, CMI response was increased significantly at 48 hours, suggesting that a simple laparotomy boost the immune defense response.

Infection due to cytomegalovirus is a substantial cause of morbidity and mortality in immunocompromised patients. In particular, cytomegalovirus infection has been associated with a significant detrimental effect on patient and allograft survival after solid-organ transplantation. We are evaluating a new antiviral agent, ganciclovir 9-[1,3-dihydroxy-2-2 propoxymethyl] guanine (DHPG), used in solid-organ transplant recipients who developed life-threatening cytomegalovirus infections. Between March 1, 1987, and June 30, 1989, we treated 93 solid-organ transplant patients who developed tissue-invasive cytomegalovirus disease. From this group of patients we have identified 14 patients with primary gastrointestinal cytomegalovirus disease who received treatment with DHPG. Tissue diagnosis was made by endoscopy of the upper gastrointestinal tract (11 patients) or colonoscopy (three patients). Invasive cytomegalovirus disease was identified prior to severe complications of the gastrointestinal tract in all but one patient, who suffered colonic perforation prior to treatment with DHPG and subsequently died of bacterial sepsis. While 13 of the 14 patients improved after treatment with DHPG, four patients required additional treatments for recurrent cytomegalovirus disease and recovered. No DHPG toxicity was observed. We believe treatment with DHPG is indicated in this patient population, but that further studies are indicated to fully define the impact of this recommendation on both patient and allograft survival after solid-organ transplantation.

Infection is the most dreaded complication associated with implantation of a prosthetic arterial graft. The reported incidence of primary graft infection varies from 1.3% to 6.0%, with a mortality rate from this complication as high as 75%. Although remote bypass followed by complete removal of the infected prosthesis has proven to be a satisfactory method of treatment, in certain instances remote bypass alone is not feasible and other modes of surgical treatment must be employed. Such conservative methods of management of infected aorto-iliac-femoral prosthesis sometimes irradicate infection. The only certain cure, however, is obtained by totally removing the graft. And the success of extra-anatomic axillofemoral techniques has led to its extended use. The addition of a cross-limb on an axillo-unilateral femoral graft to form an axillobilateral femoral graft was described by Sauvage and Wood, reasoning that the higher flow rate in the axillary limb of the axillobilateral femoral graft would result in an improved patency rate compared with that of axillounilateral femoral grafts. Additionally, both medial (obturator foramen) and lateral extra-anatomic remote bypass of infected femoral prosthesis have been used, successfully. The current case illustrates the complexity of management, once sepsis occurs. It further focuses on groin, retroperitoneal and bilateral axillo-femoral tract infection with prolonged (apparently innocuous) graft exposure and finally points out the utility of the ascending aorta as an alternative extra-anatomic inlet to perfuse the lower extremities.

Thirty-two patients undergoing limb salvage procedures for complex vascular and orthopedic injuries of the lower extremity were studied in order to identify prognostic indicators for delayed amputation in this select group. A high incidence of nerve (38%), soft tissue (66%), and remote injury (47%) was noted. A comprehensive and integrated approach to vascular, orthopedic, and plastic reconstruction was utilized. Of the 32 patients studied, 1 (3.1%) died as a result of remote injury and sepsis. Amputation was required in 9 patients (28%), while 13 (56%) of the patients with limb salvage showed persistent functional or neurologic deficits. Infection was the most significant factor associated with amputation (p less than 0.0005) and was not avoided by the perioperative use of antibiotics. Delayed amputation resulted in a significant extension of total hospitalization (p less than 0.005). The authors favor an aggressive approach to limb salvage with IIIC injury but recommend early amputation in the presence of significant nerve disruption. An attentive use of tissue debridement, intravenous antibiotics, and early wound coverage is needed to limit infection.

Infection is a frequent cause of morbidity and mortality after multiple trauma. Although impaired immune function has been assumed to be associated with the development of infection and sepsis in trauma victims, its predictive role is still controversial. In a prospective study, the predictive value of the immunological in vivo response to intradermally applied recall antigens was compared with serial determinations of routine parameters. PATIENTS AND METHODS. Using the commercially available Multitest device, the cutaneous delayed-type hypersensitivity (DTH) response to seven standardized recall antigens was sequentially tested at defined time intervals in 35 mechanically ventilated multiple-trauma patients (4 females, 31 males). Routine clinical and laboratory parameters (FiO2, lactate, creatinine, platelet count, absolute and differential white blood cell (WBC) count) were determined every day. Injury severity scores (ISS), infections, and intensive care unit (ICU) mortality were prospectively documented by the same investigator. RESULTS AND DISCUSSION. The overall ICU mortality was 23%. In survivors, the mean ISS was 29.5, in nonsurvivors 38.9 (P less than 0.05). Mortality significantly increased in association with sepsis. Interestingly, the DTH response and severity of the trauma did not show any interdependence. Immediately after ICU admission, DTH testing failed to correlate with either infection or mortality: most of the multiply traumatized patients were anergic on initial skin testing. In the early posttraumatic stage, the serum levels of creatinine or lactate, lymphocyte and promyelocyte counts, and FiO2 proved to be more reliable predictors. In the later course, however, a good correlation was found between sequential skin test results and the development of infection. Beginning on the 4th day after trauma, DTH scores below 5 mm defined a population with a high incidence of developing a clinically important septic episode. In conclusion, lactate, FiO2, and WBC counts are early indicators of an impending poor outcome, whereas the skin test response is not. In the later course, however, the sequentially determined DTH response may substantially contribute to the identification of multiple-trauma patients at increased risk of infection.
