Between May 1975 and August 1991, 184 patients with transposition of the great arteries (TGA) were operated upon by Jatene operation. One hundred and sixteen underwent corrective surgery prior to June 1987 with a follow-up period of between 50 and 182 months. The ages of these 116 patients ranged from 1 day to 84 months (11.53 +/- 15.98). Eleven percent were less than 1 month old, 38% were between 1 and 6 months, 29% between 7 and 12 months and 22% were older than this. Eighty-eight patients (76%) were boys and the weight ranged from 2.4 to 17.0 kg (6.39 +/- 3.38). Thirty-eight patients (20.7%) died in the immediate postoperative period. Of the survivors, 5 died in the late follow-up between 9 and 66 months (endocarditis at 9 and 66 months; gastroenteritis at 20 months; sudden death at 48 months; and during reoperation for relief of pulmonary stenosis (PS) at 60 months). Of the surviving 73 patients, 24 (32.9%) are anatomically normal at a mean period of 92.5 months postoperatively. Twenty-two (30.1%) have dysfunctions without clinical repercussion. Nineteen (26%) have had no recent evaluation and 8 (11%) were submitted to reoperation or angioplasty for relief of PS. Ninety-eight percent of the patients have normal left ventricular function. The majority of the patients surviving 50 to 182 months are in good clinical condition and if dysfunctions are present these show no progression or severe hemodynamic alterations.

The common infective conditions encountered at King Khalid Teaching Hospital, Riyadh, Saudi Arabia were described. These data were collected mostly during a period of 8 years between 1981 to 1988. These infections included brucellosis, cholecystitis, conjunctivitis, enteric fever, gastroenteritis, infective endocarditis, meningitis, otitis media, pneumonia, septicaemia, sorethroat, treponemal infections, urethritis, urinary tract infections, and vaginitis. A scheme for empiric chemotherapy has been suggested for these infections based on the sensitivity results obtained mostly from the microbiology laboratory at Teaching Hospital, Riyadh. This scheme of empiric therapy is offered as a guide only. It does not cover all possibilities and is not intended as a rigid dogma. Empiric therapy has also been suggested for some other infective conditions where sufficient data were not available from the Teaching Hospital. Empiric therapy should be started after relevant specimens are collected. Culture and sensitivity tests are invaluable in the management of patients with infectious diseases. As soon as sensitivities of the infecting organisms' are known, treatment should be adjusted accordingly. In some cases, Gram-staining is valuable to guide the initial therapy (eg. meningitis, pneumonia, and urethritis). Finally, close liaison between physicians and clinical microbiologists is mandatory for successful therapy.

Many discriminative experimental animal models of infection have been utilized in the evaluation of newer fluoroquinolones. In vivo efficacy of many of the newer agents has been shown in experimental models of meningitis, endocarditis, pneumonia, urinary tract infections, pyelonephritis, osteomyelitis, abscesses of various types, septic arthritis, gastroenteritis, salmonellosis, listeriosis, tuberculosis, syphilis, sinusitis, prostatitis and burn wound sepsis, among others. This review focuses on recent developments in a few selected areas. Although the limitations of animal model studies are well described, these results provide a rationale for the appropriate clinical usage of the newer fluoroquinolones in humans.

Five cases of neonatal infective endocarditis are reported. The mitral, tricuspid and pulmonary valves were involved either alone or in association. The predisposing factors were multiple: umbilical catheter, respiratory distress with assisted ventilation, septicemia, osteoarthritis or gastroenteritis. Only one child had a minor cardiac malformation. The causal organism was a staphylococcus aureus in all cases. All children had disseminated intravascular coagulation and a cardiac murmur. The diagnosis was confirmed by echocardiographic demonstration of bacterial vegetations. Three of the 5 children died despite long-term antibiotic therapy. In one case, a vegetation embolised to the pulmonary artery. In the two cured neonates the vegetations disappeared. These cases illustrate the value of echocardiography which should be performed in all neonates with septicemia or disseminated intravascular coagulation, especially when there is an associated cardiac murmur.

Although animal models of infection are associated with certain limitations in interpretation, properly performed studies provide important information for evaluating the efficacy of new antimicrobial agents in the treatment of human disease. The antibacterial efficacy of the newer quinolones, particularly ciprofloxacin, has undergone extensive evaluation in several animal models. Efficacy has been demonstrated in animal models of pneumonia, endocarditis, meningitis, skin and soft-tissue infections, septic arthritis, burn wound sepsis, empyema, intra-abdominal abscess, osteomyelitis, prostatitis, sinusitis, urinary tract infection, chronic gastroenteritis, granuloma pouch infection, and Pseudomonas septicemia. More recent studies have evaluated the efficacy of ciprofloxacin in animal models of tuberculosis and syphilis, as well as in infections caused by the intracellular pathogens Salmonella typhimurium, Legionella pneumophila, and Listeria monocytogenes.

While salmonellosis is often considered to affect primarily the gastrointestinal tract, infection at other sites may occur, producing characteristic clinical syndromes. We reviewed cases from our institutions and the literature on focal manifestations of salmonella infections. In the past, most extra-intestinal salmonella infections were caused by S. choleraesuis; however, we found S. typhimurium to be the predominant serotype. The mortality rate for patients in our series was considerably lower than the rate described for focal infections in other reviews. This may in part be due to lower proportion of infections due to S. choleraesuis, improved microbiologic and diagnostic techniques, increased use of ampicillin, and improved surgical techniques. Salmonella endocarditis usually occurs in patients with preexisting heart disease. Unlike other salmonella infections, S. choleraesuis is the most frequent serotype. Salmonella endocarditis is often very destructive, with a fatality rate of 70%. Nonvalvular (mural) endocarditis occurs in one-fourth of patients and survival has not been reported. While antibiotic therapy should be tried initially, if response is not prompt the clinician should look for an associated site of infection (intra- or extra-cardiac abscess), which will often require surgery. Salmonella pericarditis often presents with cardiac or pulmonary symptoms, but typical signs of pericardial disease (pulsus paradoxus, friction rub) or characteristic electrocardiographic changes (low voltage, elevated ST segments) are uncommon. Early diagnosis, before infection involves other areas of the heart, is crucial for survival. In addition to antibiotic therapy, pericardiocentesis or pericardiectomy is required. Salmonella may infect the peripheral or visceral arteries, but the abdominal aorta is the most frequent site of vascular infection. Most patients are men over age 50 with preexisting atherosclerosis of the aorta who do not have a previous history of gastroenteritis. About one-fourth of patients have associated lumbar osteomyelitis. No patients have been reported to survive with medical therapy alone. Specific guidelines for surgical removal of infected aneurysms have been proposed and these (in addition to increased use of ampicillin) may be responsible for higher survival rates in recent years. Due to the high incidence of relapses, postoperative blood cultures should be done routinely. Arterial infection should be considered in any elderly patient with salmonella bacteremia especially with prolonged fever or bacteremia after an "adequate course" of antibiotic therapy.(ABSTRACT TRUNCATED AT 400 WORDS)

The antibacterial efficacy of some of the newer quinolone antimicrobial agents in general, and ciprofloxacin in particular, in animal models of experimental septic arthritis, burn wound sepsis, empyema, chronic gastroenteritis, granuloma pouch infection, intraabdominal abscess, osteomyelitis, prostatis, sinusitis, urinary tract infection, and severe septicemia caused by Pseudomonas aeruginosa is reviewed. In addition, the efficacy of these newer quinolones has been studied in animal models of pneumonia, endocarditis, meningitis, skin and soft tissue infections, and a variety of other systemic infections. Although certain limitations are associated with animal models of infection, properly performed studies clearly have the potential to provide guidelines for evaluating the efficacy of antimicrobial agents in the treatment of some infections in humans.

Endocarditis and mycotic aneurysm of the great blood vessels are two serious complications of non-typhoidal salmonella gastroenteritis. Two patients are presented, the first with endocarditis due to S. dublin cured by combined treatment with ampicillin and gentamicin, the second with a fatal aneurysm of the aorta caused by Salmonella infantis. Salmonella endocarditis, particularly with left-sided cardiac involvement, has an especially poor prognosis. Survival is rare without surgery. Chemotherapy should consist of a synergistic combination such as ampicillin with an aminoglycoside for a period of 4-6 weeks. Mycotic aneurysm generally results from haematogenous infection of a previously damaged arteriosclerotic vessel. Salmonella spp. cause approximately 20% of all mycotic aneurysms and there is some evidence to suggest that their role is increasing. Repeatedly positive blood cultures in spite of antimicrobial treatment in an elderly patient should raise the suspicion of an endovascular localisation of the infection. Rapid surgical intervention and appropriate chemotherapy are needed before rupture takes place.

The epidemiology of salmonellosis has undergone a change during the last 2 years. An increase in the number of cases of enteritis and sepsis caused by Salmonella enteritidis has been observed. We report on the case of a 65-year-old woman with mitral valve endocarditis due to Salmonella enteritidis. The infective endocarditis occurred without prior episodes of gastroenteritis. After having undergone prosthetic valve replacement and antibiotic therapy with ciprofloxacin, the patient recovered completely.

Enterococci are gram-positive bacteria and fit within the general definition of lactic acid bacteria. Modern classification techniques resulted in the transfer of some members of the genus Streptococcus, notably some of the Lancefield's group D streptococci, to the new genus Enterococcus. Enterococci can be used as indicators of faecal contamination. They have been implicated in outbreaks of foodborne illness, and they have been ascribed a beneficial or detrimental role in foods. In processed meats, enterococci may survive heat processing and cause spoilage, though in certain cheeses the growth of enterococci contributes to ripening and development of product flavour. Some enterococci of food origin produce bacteriocins that exert anti-Listeria activity. Enterococci are used as probiotics to improve the microbial balance of the intestine, or as a treatment for gastroenteritis in humans and animals. On the other hand, enterococci have become recognised as serious nosocomial pathogens causing bacteraemia, endocarditis, urinary tract and other infections. This is in part explained by the resistance of some of these bacteria to most antibiotics that are currently in use. Resistance is acquired by gene transfer systems, such as conjugative or nonconjugative plasmids or transposons. Virulence of enterococci is not well understood but adhesins, haemolysin, hyaluronidase, aggregation substance and gelatinase are putative virulence factors. It appears that foods could be a source of vancomycin-resistant enterococci. This review addresses the issue of the health risk of foods containing enterococci.
