Group G streptococci which have been isolated from the oral flora of rats are also normal inhabitants of the human skin, oropharynx, gastrointestinal tract, and female genital tract. This group of streptococci can cause a wide variety of clinical diseases in humans, including septicemia, pharyngitis, endocarditis, pneumonia, and meningitis. Ten days after oral gavage with 7,12-dimethylbenz[a]anthracene, 12 of 22 two-month-old, female, outbred, viral-antibody-free rats presented with red ocular and nasal discharges and marked swelling of the cervical region. Various degrees of firm, nonpitting edema in the region of the cervical lymph nodes and salivary glands as well as pale mucous membranes and dehydration were observed. Pure cultures of beta-hemolytic streptococci were obtained from the cervical lymph nodes of three rats that were necropsied. A rapid latex test system identified the isolates to have group G-specific antigen. These streptococcal isolates fermented trehalose and lactose but not sorbitol and inulin and did not hydrolize sodium hippurate or bile esculin. A Voges-Proskauer test was negative for all six isolates. Serologic tests to detect the presence of immunoglobulin G antibody to rat viral pathogens and Mycoplasma pulmonis were negative. Histopathologic changes included acute necrotizing inflammation of the cervical lymph nodes with multiple large colonies of coccoid bacteria at the perimeter of the necrotiz zone. To our knowledge, this is the first report of naturally occurring disease attributed to group G streptococci in rats.

Antiribitol-teichoic acid antibody (ARTA) was detected in sera of 30 out of 50 patients (60%) with various acute deep seated Staphylococcus aureus infections and 5 out of 10 chronic osteomyelitis cases, whereas none of the sera from 50 patients with superficial Staphylococcus aureus infections as well from 50 patients without Staphylococcus aureus infections showed antibody response (p less than 0.01). This test is a definite advantage in diagnosis of deep seated staphylococcal infections like endocarditis, lung disease, meningitis and specially in osteomyelitis cases where organisms cannot be isolated and therefore helps in predicting the need for long term antimicrobial therapy.

Neurologic syndromes often complicate the management of infective endocarditis (IE). We retrospectively reviewed 166 episodes of native valve endocarditis to assess the occurrence and implications of nonfocal encephalopathy, meningitis, salient headache, back pain, and brain abscess. Neurologic complications occurred in 35% (58/166) of patients: 41% (54/133) of mitral or aortic valve IE and 12% (4/33) of tricuspid valve IE. Of 133 cases of mitral or aortic valve IE, encephalopathy occurred in 14%, meningitis in 5%, and salient headache in 3%. All neurologic complications occurred more often with Staphylococcus aureus infection (67%) than with viridans streptococci (22%), including encephalopathy (22% versus 7%), meningitis (17% versus 0%), stroke (39% versus 16%), and death (39% versus 9%). Encephalopathy was associated with virulent organisms, increased patient age, and uncontrolled infection. Clinical, radiologic, and neuropathologic data all suggest that infective microemboli are often etiologic in IE-related encephalopathy. There were no macroscopic brain abscesses clinically identified. Meningitis occurred only with virulent organisms. While many clinical aspects of IE have changed in recent years, the frequency and gravity of neurologic complications have not.

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.

Parenteral ceftriaxone was administered as a once-daily outpatient treatment to a selected low-risk population of neonates, infants, and children with moderate to severe bacterial infections. No incidences of treatment failure were seen in 200 children with uncomplicated infections responsive to ceftriaxone therapy. The mean period of outpatient treatment in initially hospitalized children with non-CNS infections, excluding endocarditis, was 1-3 days. Ceftriaxone outpatient management was successful in the control of organisms causing meningitis (n = 54), periorbital facial cellulitis (n = 16), sinusitis (n = 10), arthritis (n = 6), endocarditis (n = 4), and other infections.

Orthotopic cardiac transplantation has become established for selected infants with severe forms of congenital heart disease. This study reviews the combined experience and intermediate term results of infants undergoing orthotopic cardiac transplantation from Children's Memorial Hospital, Chicago, and Kosair Children's Hospital, Louisville. From June 1986 through December 1989, 20 orthotopic cardiac transplantations were performed in 19 patients. Sixteen patients had variants of hypoplastic left heart syndrome. One infant had anomalous origin of the left coronary artery with severe ischemic cardiomyopathy. Two infants had aortic stenosis with endocardial fibroelastosis, and one had extracorporeal membrane oxygenation as a bridge to transplantation. Immunosuppression included cyclosporine, azathioprine (Imuran), and corticosteroids with an effort to wean the patients from steroids by 6 months to 2 years. Three early deaths resulted--from technical errors in two patients and from hyperacute rejection in one patient at 3 days. Four late deaths have occurred. Two patients died at 2 and 13 months of acute rejection. One patient died at 15 months of acute rejection after retransplantation. One patient died at 7 months of respiratory syncytial viral pneumonia. The remaining 12 patients are surviving 5 to 47 months (means 20 months) after orthotopic cardiac transplantation. Rejection surveillance in the first 6 months is by clinical signs supplemented by echocardiography, electrocardiography, and cell cycle analysis; endomyocardial biopsy is used after 6 months of age. For the cumulative series, 24 episodes of suspected rejection have been treated during 277 at-risk patient months with intravenous methylprednisolone (Solu-Medrol) (n = 18) and monoclonal antibody (OKT3) (n = 6), for an incidence of 1.04 episodes of rejection per patient per year. Serious posttransplantation infections including endocarditis, catheter sepsis, meningitis, and colonic perforation were successfully treated in four patients. Subjectively, their quality of life is excellent as shown by normal growth and developmental milestones and a low hospital readmission rate (1.4 episodes per patient per year). These encouraging intermediate term results warrant continued application of infant orthotopic cardiac transplantation for severe forms of congenital heart disease.

Many kinds of microorganisms can produce toxic septicemia in immunocompromised hosts. We are reporting alpha-hemolytic streptococcal septicemia and meningitis in two children with hematological malignancies. [Case 1] 6 year old girl who had been suffering from acute lymphocytic leukemia. She had sepsis and bacterial meningitis in maintenance-therapy for leukemia. Streptococcus sanguis was isolated from the blood and cerebrospinal fluid (CSF). [Case 2] 11 year old girl who had had malignant lymphoma (non-Hodgkin type). She also had sepsis and bacterial meningitis due to Streptococcus mitis which was isolated from blood and CSF in maintenance-therapy. Both cases had been treated with anti-cancer drugs and had severe granulocytopenia. Positive rate of blood cultures during the recent 6 years (1984.1-1989.12) at our department was 6.0% (total number of cultures were 2,019, positive cultures were 121). Strains of 131 bacteria were determined; Gram-positive cocci were 70 strains (53.4%) and Gram-negative rods were 52 strains (39.7%). Fifteen strains (11.5%) of alpha-hemolytic Streptococci were isolated during 6 years. One hundred thirteen cases of septicemia were analysed in medical charts and 12 cases of alpha-hemolytic streptococcal septicemia were observed (5 cases with infective endocarditis and 7 cases in immunocompromised states).

We review the syndrome of Capnocytophaga canimorsus (DF-2) septicemia after exposure to dogs or cats. We describe a previously healthy patient who developed diffuse intravascular coagulation and symmetrical peripheral gangrene as a result of C. canimorsus septicemia after a dog bite. To our knowledge, this patient was the first to receive combined plasmapheresis and leukapheresis for C. canimorsus septicemia. Symmetrical peripheral gangrene is frequently associated with C. canimorsus septicemia and may lead to an early diagnosis in patients who become severely ill after a dog bite. Other complications include arthritis, meningitis, and endocarditis. These manifestations can also be found in previously healthy patients, although a prior splenectomy or other causes of impaired host defense clearly enhance the risk. Prompt treatment with penicillin G is required.
