Thirty children over the age of one month were treated with amikacin (BBK8), a new aminoglycoside derived from kanamycin A, with three intramuscular dosage schedules. Each group consisted of ten patients. The first received 7-5 mg/kg/12 hours, the second 7-5 mg/kg/24 hours and the third, 3-75 mg/kg/12 hours. The infections and the bacteria were similar in all three groups: pyelonephritis, abscesses of soft tissues, infected wounds, septicaemia, superinfected empyema, gastro-enteritis, chronic otitis media; the bacteria were E. coli, Klebsiella, Pseudomonas and Salmonella. A were sensitive by the Kirby-Bauer method, although two were resistant by dilution in Petri dish. Of the thirty patients, twenty four (80%) were cured. The schedule of 3-75 mg/kg/12 hours was as effective as the schedule of 7-5 mg/kg/12 hours for infections such as pyelonephritis, superficial abscesses, contaminated wounds, gastro-enteritis and sepsis. The cases with infections localized in rather unaccessible sites required double the dose and strict drainage and cleanliness. Plasma levels with the administration of 3-75 mg/kg fluctuated between 8-3 and 12-6 mcg/ml; with 7-5 mg/kg they fluctuated between 8-6 and 13-1. The minimum inhibitory level (MIL) for the majority of the bacteria was 1-25 mcg/ml. No toxic reactions were observed.

In childhood perianal fistulas are frequent. The origin of the fistula is the anorectal line, especially from the Morgagni crypts. Local recurrence of abscesses are observed. Due to two observations we conclude that the fistulas caused a sepsis with E. coli. In one case meningitis and a consecutive empyema occurred, in a second case pyelonephritis. In the following we describe the patient with meningitis and subdural empyema.

Removal of the intravenous line, improvement of attitude and appetite and early discharge from the hospital can be achieved when sequential parenteral-oral antibiotic therapy is used appropriately to treat children with certain moderate to severe infections. Such antibiotic regimens are potentially indicated for suppurative skeletal infections, bacterial endocarditis, pneumonia with or without empyema, pyelonephritis and, perhaps, meningitis. To be effective, serum bactericidal activity against the causative pathogen after oral therapy must be comparable to that achieved after parenteral administration. Patient and parent compliance, adequate absorption and drug interactions are some of the factors that should be considered to assure a successful course of parenteral-oral antibiotic therapy.

One hundred and four children who were hospitalized for documented or suspected non-CNS bacterial infections (56 males/48 females, 22 days to 15 years old) were treated with intravenous imipenem/cilastatin for 9.4 days (range 3 to 28 days). Children up to three years of age received 100 mg/kg/day and older children 60 mg/kg/day, administered in four divided doses. Bacterial pathogens were isolated before therapy in 85%. Diagnoses in the 74 evaluable patients included bronchopneumonia with or without empyema (20%), peritonitis complicating appendicitis (16%), skin/soft tissue abscesses (14%), septicemia (11%) and miscellaneous other infections (39%). Among evaluable patients, 95% were clinically cured or improved. One patients, a marasmic child with pneumonitis due to pseudomonas, died during therapy. One evaluable patient each with shigellosis, Klebsiella pneumoniae empyema and streptococcal pneumonia had bacteriologic eradication or suppression but, due partly to noninfectious complications, had no overall clinical improvement. Most bacterial isolates (101/108) were eradicated, including many gram-negative and gram-positive aerobes and anaerobes; three pathogens persisted (one Proteus mirabilis and one Salmonella typhi, one Staphylococcus aureus); and one Escherichia coli pyelonephritis recurred after therapy ended too early. Imipenem/cilastatin was well tolerated by 91% of children. Clinical adverse experiences (AEs), none serious except for the one death, occurred in 19%; 12% were judged possibly related to imipenem/cilastatin, but none probably or definitely related. No serious laboratory AEs occurred; the most common AEs were eosinophilia (11%), urine discoloration, and infusion site pain. Imipenem/cilastatin is well tolerated and has excellent clinical efficacy in a wide variety of pediatric infections.

Ceftizoxime (FK 749, CZX) was evaluated in 24 children with a suspicion of bacterial infection. Of the 17 confirmed bacterial infections, 16 were shown to be effective (effective rate, 94.1%). The diagnosis included acute pharyngitis (2), pneumonia (6), staphylococcal empyema (1), cervical purulent lymphadenitis (2), acute enterocolitis (2), acute pyelonephritis (1), SSSS (1) and suspected septicemia (2). The etiological pathogens recovered were Streptococcus anginosus (1), Streptococcus pneumoniae (1), Staphylococcus aureus (2), Haemophilus influenzae (3), enteropathogenic Escherichia coli (1) etc. A case of suspected Pseudomonas aeruginosa septicemia was not effectively treated with CZX. The serum half-life of CZX was 1.36 hours after intravenous bolus infection. A cerebrospinal fluid level of CZX was 6.2 mcg/ml 1 hour after intravenous bolus injection of 1 g (23.8 mg/kg) in a child with inflamed meninges. No severe adverse reaction was encountered with the CZX therapy. The data suggest that CZX is an excellent candidate for the first choice parenteral antibiotic in the pediatric infections.

There are multiple etiologies reported as causes of lung abscess; however, this differential rarely includes intra-abdominal abnormalities other than extension of a hepatic process. We describe a patient who was found to have a lung abscess and empyema resulting from the development of a nephrobronchial fistula secondary to nephrolithiasis and pyelonephritis. The patient had no urinary symptoms or known abdominopelvic infection and the etiology of lung abscess was only incidentally discovered after chest CT revealed extension of pleural fluid below the diaphragm.

Staphylococcus aureus remains a prominent cause of community- and hospital-acquired infection. This study reviewed 162 cases of S. aureus infection occurring in 120 adults who were hospitalized at a Veterans Affairs Medical Center and referred for consultation to the Infectious Disease Service. There were 37 cases of skin and soft tissue infection, 5 pyomyositis, 34 osteomyelitis, 13 septic arthritis, 19 pneumonia, 3 empyema, 5 pyelonephritis, 37 vascular infection, 3 epidural abscess, and 6 miscellaneous infections. Bacteremia was documented in 56 of 119 (47%) cases in which blood cultures were obtained, indicating the serious nature of the infections in many cases. Staphylococcus aureus is widely prevalent in healthy persons. Given its ubiquity and the capacity to cause a broad array of infections, an effective host response must play an important role in preventing infection. This host response is immunologically nonspecific, in that it depends upon the effectiveness of mechanical barriers to invasion and, once invasion takes place, the interaction of PMN, complement, and antibody that is probably present in serum of all immunologically competent adults rather than sensitization of B or T lymphocytes by any identifiable antigens specific to S. aureus. Analysis of the present cases calls attention to S. aureus as an opportunistic pathogen, 1 that only infrequently causes serious infection in otherwise healthy persons. Nearly every patient in this series had 1 or more medical condition thought to predispose to infection; 279 such conditions were identified, representing an average of 2.3 per person. A break in the natural barrier to infection was also present in the majority of cases, for example, trauma, wound, or pre-existing decubitus ulcer in skin and soft tissue infections; endotracheal tube in pneumonia; and a catheter bypassing urethra or skin in urinary and vascular infections, respectively. The tendency for patients to be infected with S. aureus repeatedly (mean number of infections, 1.4 per patient) reflects the chronicity of many predisposing factors and, perhaps, of colonization as well. Staphylococcus aureus has a special predilection to cause infections involving prosthetic devices, perhaps related to its affinity for fibronectin, laminin, and other serum proteins that can mediate attachment to foreign material; 46 of 162 (28%) infections were associated with the presence of a foreign body. Such infections are difficult to eradicate with antibiotic therapy alone, perhaps because of a change in the metabolic state of adherent bacteria, and removal of the foreign body is generally required for cure.(ABSTRACT TRUNCATED AT 400 WORDS)

Nursing home-associated infections and antibiotic resistant pathogens constitute common and serious problems in the geriatric population.Chryseobacterium indologenes, a non-motile Gram-negative rod, though widely distributed in nature, is an uncommon human pathogen. Typically thought of as an organism of low virulence, it may cause serious infections, particularly among the immunocompromised. The majority of reported cases are nosocomial, often associated with immunosuppression or indwelling catheters. It has been reported as the causative agent in bacteraemia, peritonitis, pneumonia, empyema, pyelonephritis, cystitis, meningitis and central venous catheter-associated infections. We report a rare case of C. indologenesinfection affecting a nursing home resident in the USA and we provide a review of similar cases. This report emphasises the importance of individualised treatment and promotes awareness about this organism as one of several emerging pathogens in immunocompromised adults and in the frail elderly who are often nursing home residents, in the Western Hemisphere.

Antibiotic-resistant pathogens and nosocomial infections constitute common and serious problems for neonates admitted to neonatal intensive care units worldwide. Chryseobacterium indologenes is a non-lactose-fermenting, gram-negative, health care-associated pathogen (HCAP). It is ubiquitous and intrinsically resistant to several antibiotics. Despite its low virulence, C. indologenes has been widely reported to cause life-threatening infections. Patients on chronic immunosuppressant drugs, harboring invasive devices and indwelling catheters become the nidus for C. indologenes. Typically, C. indologenes causes major health care-associated infections such as pneumonia, empyema, pyelonephritis, cystitis, peritonitis, meningitis, and bacteremia in patients harboring central venous catheters. Management of C. indologenes infection in neonates is not adequately documented owing to underreporting, particularly in India. Because of its multidrug resistance and the scant availability of data from the literature, the effective empirical treatment of C. indologenes is challenging. We present an uncommon case of bacteremia caused by C. indologenes in a preterm newborn baby with moderate respiratory distress syndrome who was successfully treated. We also provide a review of infections in the neonatal age group. Henceforth, in neonates receiving treatments involving invasive equipment use and long-term antibiotic therapy, multidrug resistant C. indologenes should be considered an HCAP.

A 27-year-old healthy woman developed spontaneous right-sided orbital cellulitis, followed by left hemiparesis and cranial nerve palsies. MRI revealed underlying basal exudates and vasculitic infarction involving the pons and cerebellar peduncles, following which a cerebrospinal fluid examination confirmed acute bacterial meningitis. Although the patient remained afebrile, imaging revealed asymptomatic septic foci in bilateral lungs, empyema and pyelonephritis. Blood culture grew drug-resistant Klebsiella pneumoniae The case highlights the absence of fever in an immune-competent patient presenting with young-onset stroke secondary to meningitis.
