Viridans streptococci continue to be the most common etiologic agents in bacterial endocarditis. The spectrum of diseases other than endocarditis caused by these organisms, however, has received sparse attention. Moreover, little clinical information is available concerning the individual viridans streptococcal species. During the 16 months of this study, one species of viridans streptococci, Streptococcus milleri, caused a surprising number of clinically significant suppurative infections. Clinical syndromes included the following: abscesses, 10 cases; peritonitis, four cases; endocarditis, three cases; cholangitis, empyema and cellulitis, one case each. A gastrointestinal source was apparent in eight of these 20 cases. Review of 58 cases of viridans streptococcal endocarditis demonstrated that although Strep. milleri was an infrequent cause of endocarditis, this species was associated with an unusual frequency of suppurative complications. Our experience suggests that Strep. milleri may be more commonly associated with serious suppurative infections than other viridans streptococci and that species identification may be a clinically useful procedure.

Endoscopic retrograde cholangiopancreatography (ERCP) may be complicated by bacteremia, cholangitis, or biliary sepsis. Bacteremia during ERCP implies a potential risk of endocarditis in patients with valvular prostheses or a previous history of infectious endocarditis. For these patients antibiotic prophylaxis prior to ERCP is recommended. Cholangitis or biliary sepsis may develop after ERCP in patients with obstructed bile ducts. In these patients antibiotics should be administered until adequate drainage of biliary obstructions is achieved. Antibiotic prophylaxis and antibiotic therapy must consider the spectrum of micro-organisms which is normally found in each of these situations. Regarding bacteremias associated with ERCP gram-positive cocci predominate, whereas cholangitis and biliary sepsis are caused mainly by gram-negative rods like Escherichia coli, Pseudomonas aeruginosa, or Klebsiella spp.

The authors have evaluated the efficacy and tolerance of teicoplanin against Gram-positive infections in 8 patients (four with endocarditis, one with cholangitis, one with purulent arthritis, one with gathered fistula and one with general pyoderma), arose both in the immunocompetent and immunodepressed subjects. All patients received IM teicoplanin at a dosage of 200-400 mg/die, according to the severity of the infectious process. Teicoplanin proved to be an effective and well-tolerated drug in the treatment of staphylococcus infections, both for immunocompetent and with serious deficit of the immune system subjects.

Although the first Aeromonas strain was described by Zimmermann as early as in 1890, it took 60 years until Caselitz established human pathogenicity of strains then called "Vibrio jamaicensis". Since then, and especially in the last 10 years, there have been increasing numbers of reports on different infections caused by members of the genus Aeromonas. These include sepsis; meningitis; cellulitis; necrotizing fasciitis; ecthyma gangrenosum; pneumonia; peritonitis; conjunctivitis; corneal ulcer; endophthalmitis; osteomyelitis; suppurative arthritis; myositis; subphrenic abscess; liver abscess; cholecystitis and/or ascending cholangitis; urinary tract infection; endocarditis; ear, nose, and throat infections; balanitis; etc. The role of Aeromonas in gastrointestinal disease is very controversial. Increasing epidemiological data suggest that these organisms play a major role in enteric infections, but so far enteropathogenicity has not been demonstrable in experiments where volunteers were given high numbers of Aeromonas possessing different virulence factors. Virulence factors include hemolysin(s), enterotoxin(s), hemagglutinins, invasivity, and others; but these are not found more frequently in strains isolated from patients with diarrhea than from healthy controls. Whether there is a correlation between species and disease remains to be elucidated and requires more information about the taxonomy of this genus.

The purpose of this study was to determine the incidence of death as the initial manifestation of cholelithiasis. Records of patients who died or underwent cholecystectomy for gallstone-related disease at Duke University Medical Center between 1976 and 1985 were reviewed. Thirty patients died, six of whom (20%) had previous episodes of biliary pain and stone documentation. Twenty-four (80%) were asymptomatic (three with previous incidental diagnosis of cholelithiasis). Reason for admission included acute cholecystitis (nine), pancreatitis (eight), biliary pain (six), cholangitis (four), jaundice (one), and endocarditis (one). Three patients died of gallstone complications without surgical intervention; one patient had renal failure and two had septicemia. Other causes of death were: sepsis (seven patients), cardiac failure (six), pulmonary complications (four), renal failure (three), cerebrovascular accident (three), liver failure (two), pancreatitis (one), and gastrointestinal bleeding (one). During this period, 1731 cholecystectomies were performed without mortality. In this group, the patients were younger (50 +/- 8 years vs. 64 +/- 13 years, p less than 0.001), and had a lower incidence of cirrhosis (p less than 0.001) and diabetes (p less than 0.002). The sex ratio was inverted (p less than 0.001). This study demonstrates that death from gallstones is uncommon (three cases per year), as is death from their initial clinical manifestation (1.2%). The risk of death is two- and ninefold higher in patients with acute cholecystitis or acute pancreatitis. Age, cirrhosis, and diabetes are important determinants of outcome.

In a prospective study 43 patients (19 men, 24 women) suffering from severe bacterial infections such as peritonitis (n = 16), soft tissue infection (n = 12), pneumonia (n = 7), septicemia (n = 6), catheter sepsis (n = 2), cholangitis (n = 4), osteomyelitis (n = 3), complicated urinary tract infection (n = 2) or endocarditis (n = 1) were treated t. i. d. with short-time i. v. infusions of 0.5 g imipenem/cilastatin for five to 37 days (means = 9). All the patients were cured or significantly improved following therapy with imipenem/cilastatin alone or in combination with surgical intervention. The most frequent isolates were Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis, Staphylococcus aureus, Staphylococcus epidermidis and Streptococcus faecalis. 58 (83%) of the 70 pathogens isolated initially were eliminated. The 12 microorganisms (gram-negative aerobic bacteria) which persisted were non-contributory to the course of the infection and had MICs between 0.32 and 4 mg/l. The MICs for 60 isolates were less than or equal to 1 mg/l; the MICs for nine isolates were in the range of 2 to 8 mg/l. One S. epidermidis isolate presented primary resistance to imipenem (MIC 16 mg/l). The tolerability was good. Phlebitis was observed in one case only. Based on our experience we conclude that monotherapy with imipenem/cilastatin at a dosage of 0.5 g t. i. d. is appropriate for the treatment of severe bacterial infections.

The enterococci, members of the group D streptococci and the predominant aerobic streptococci of the gastrointestinal and female genital tracts, have long been recognized as significant pathogens in infective endocarditis. Over the past 2 decades, enterococci have become increasingly important nosocomial pathogens, related to their intrinsic resistance to many antibiotics, especially the cephalosporins, and the greatly increased use of antimicrobial therapy in hospitals. Recent reports have documented an alarming increase in the frequency of high-level resistance to aminoglyclosides, and strains resistant to ampicillin by production of a beta-lactamase and to vancomycin have now been encountered. We have reviewed the clinical features and course of 153 cases of enterococcal bacteremia occurring in a university hospital over the 14-year period, 1970 to 1983, 1) to understand better the importance of enterococci as human pathogens, 2) to identify the clinical features of enterococcal bacteremia, 3) to isolate those findings that help to identify associated endocarditis, and 4) to develop guidelines for more effective antimicrobial therapy of bacteremic enterococcal infections. The annual incidence of enterococcal bacteremia in our center rose three-fold over the period reviewed. In 65 cases (42%), bacteremia was polymicrobial, caused by Enterococcus and at least 1 other microorganism, usually an aerobic gram-negative bacillus. Most bacteremias were nosocomial and derived from infections of the urinary tract (29 cases), intravenous catheters (24 cases), intra-abdominal infections or surgical wounds (46 cases), burn wounds (25 cases), or cholangitis (21 cases); only 1 case originated from a pneumonia. Endocarditis was identified in association with 12 of 35 community-acquired bacteremias, but only 1 of 118 bacteremias acquired in the hospital (P less than .001). Endocarditis was also significantly associated with pre-existent valvular heart disease and cryptogenic bacteremia, and was negatively associated with polymicrobial enterococcal bacteremia (no endocarditis in 65 cases, P less than .001). Isolated enterococcal bacteremia produced an indolent infection rarely associated with shock (3 of 64 cases evaluated, all cases due to valve destruction by endocarditis); conversely, with polymicrobial enterococcal bacteremia, primarily with gram-negative bacilli, shock or disseminated intravascular coagulation developed in 50% of cases (P less than .001).(ABSTRACT TRUNCATED AT 400 WORDS)

Instead of the widely recommended approach of treating hilar carcinoma of the bile ducts by simple palliative biliary drainage, step by step a policy of primarily aiming at resection for cure has been adopted. So far in 11 out of 22 patients excision of the tumor was possible by resection of the hepatic duct confluence; in 4 cases a left hemihepatectomy had to be added because of carcinomatous infiltration of the left liver lobe or the left hepatic artery. The multiple bile duct openings remaining after resection of such tumors were reconstructed to one or two orifices and a bi- or unilateral Roux-en-Y cholangiojejunal anastomosis performed. In further 3 cases orthotopic liver transplantation was necessary to remove all visibly infiltrated tissue. In the remaining 8 patients because of documented extrahepatic carcinomatous spread palliative biliary drainage by a percutaneous U-tube or an endoprothesis was indeed considered the only reasonable measure. Despite the relatively high resectional rate of 60% and the extensive operations performed early mortality was confined to one patient who succumbed to septic endocarditis 6 weeks after the operation. At present the longest postoperative interval without recurrence amounts to 3 1/2 years. Nine patients free of recurrent disease are in perfect health; in 3 patients in whom a recurrence was observed after 1/2, 1 1/2 and 2 years meanwhile palliation was perfect. In contrast all patients with unresected tumors but carrying draining stents suffered from cholangitis and after 1 1/2 years all but one had died. In conclusion resectional therapy for hilar carcinoma seems possible with acceptable risk. Since only resection can provide potential cure and also palliation was better than that achieved by draining tubes a more aggressive attitude to the treatment of these lesions is advocated from our experience.

Systemic pathological alterations were studied in thirty-seven autopsied patients with Kawasaki disease. Systemic vasculitis was the most characteristic pathological finding and was present in all the patients. In addition to the vasculitis, there was a high incidence of inflammatory lesions in various organs and tissues: in the heart, endocarditis, myocarditis, and pericarditis; in the digestive system, stomatitis, sialoduct-adenitis, catarrhal enteritis, hepatitis, cholangitis, pancreatitis, and pancreas ductitis; in the respiratory system, bronchitis and segmental interstitial pneumonia; in the urinary system, focal interstitial nephritis, cystitis, and prostatitis; in the nervous system, aseptic leptomeningitis, choriomeningitis, gangliontis, and neuritis; in the hematopoietic system, lymphadenitis, splenitis, and thymitis. Dermatitis, panniculitis or myositis were also observed in some patients. Therefore, Kawasaki disease is a systemic inflammatory disease which mainly affects the cardiovascular system. These systemic inflammatory lesions are considered to correspond to the variegated clinical manifestaitions. The relationship between Kawasaki disease and infantile polyarteritis nodosa (IPN) were discussed, based on the clinicopathological characteristics.

A prospective, observational study of 110 patients with serious infections due to Enterococcus spp. in 6 university and community teaching hospitals in Connecticut was conducted to define the epidemiology of community and nosocomial serious enterococcal infections and to determine risk factors, including antibiotic resistances, that contribute to outcome. Serious community and nosocomial enterococcal infections involved a variety of sites, and antibiotic resistance was common. Types of infection by major organ system were cardiovascular, 54% (catheter-related bacteremia 28%, primary bacteremia 18%, endocarditis 6%, septic thrombophlebitis 1%); intra-abdominal, 13% (including cholangitis, 6%); renal, 13%; skin and soft tissue, 5%; bone and joint, 4%; pleuropulmonary, 4%; central nervous system, 3%; deep surgical wound, 3%; and endometritis, 2%. Sixty-one percent of infections were nosocomial; 48% of these occurred in the intensive care unit. Enterococcus faecium was responsible for 20% of all infections. Antibiotic resistances among the infections included high-level gentamicin resistance (26%), ampicillin resistance (10%), and vancomycin resistance (8%). Clinical cure was achieved in 64% of patients; 6.8% of patients relapsed, 6.8% had recurrence of the infection with a different pathogen, and overall mortality was 23%. Ampicillin resistance and a high acute physiology and chronic health evaluation (APACHE) II score were highly predictive of lack of cure.
