A 70-year-old man suffering from nephrolithiasis developed acute pyelonephritis following extracorporeal shock wave lithotripsy of renal stones. After 10 days, urosepsis complicated by meningitis was diagnosed, and 72 hours later he developed right panophthalmitis with perforation of the globe, which was treated by enucleation. A week later, while on cefotaxime and cefuroxime, a focal infectious process developed in the retina of the left eye's posterior pole, spreading into the vitreous and causing retinal detachment. The patient was treated by vitrectomy and retinal detachment surgery, with good anatomical results. The functional result, however, was poor. Endophthalmitis is a possible complication, through rare, of urosepsis in patients undergoing shock wave lithotripsy.

This review article discusses the stages in the development of research on group B streptococcus (GBS), otherwise called Streptococcus agalactiae. Emphasis was placed on the bacteriology, clinical spectrum of disease, immunity to GBS infections and antibiotic susceptibility of the causative organism. The organism, first recognized by Billroth in 1873, is classified into order Eubacteriales, family Lactobacillceae, class Schizomycetes and genus Streptococcus on the basis of its biochemical and physiological characteristics. It is subdivided into types Ia, Ib, Ic, II, III, X and R on the basis of carbohydrate and protein antigens present on its cell wall. Bovine strains of GBS are found in the bovine teat while human strains are present in the female vagina, the oro-pharynx, anorectum and the external auditory canal of newborns. It could be transmitted vertically from mother to child in-utero and during parturition. Cross infection by the nursery staff could also occur during the immediate post partum period. Two types of diseases are caused in the newborn: the early disease occurring within a week of birth; and the late disease presenting during the late neonatal period. The former usually presents in the form of septicaemia while the latter presents as meningitis. Adult infections include puerperal sepsis, pyelonephritis and a wide range of other infections. Usually they are associated with other underlying clinical conditions such as malignancy, diabetes mellitus and sickle cell disease. The organism is sensitive to penicillin which is the drug choice in treating established infections by GBS. Control measures are based on treatment of cases, eradication of vaginal colonization and chemoprophylaxis of infants at risk. An effective vaccine may become available in the near future.

Sixty-three Escherichia coli strains isolated from neonatal sepsis or meningitis were studied and compared with previous data on fecal or urinary pyelonephritis-associated isolates from children. Characteristics significantly associated with neonatal infection were capsular type K1 (54%), O group 18 (27%), rough-type lipopolysaccharide together with K1 capsule (19%), and S fimbriae (29%). Within the neonatal infection group, the K1 capsule and rough lipopolysaccharide were most common among the youngest infants (0 to 21 days old) and in meningitis. Hemolysin production, P fimbriae, and X adhesions (adhesions not identifiable as type 1, P, or S) were significantly more common in the two materials from infections as compared with the fecal isolates. One large clone of 11 strains (O18:K1:H7, with both type 1 and S fimbriae) and three smaller ones (O7:K1:H1 and O6:K2:H1, both with type 1 and P fimbriae and X adhesions; and R:K1:H33 with no adhesions) were identified among the strains from neonatal infections. Only O6:K2:H1 strains were also common among the strains from pyelonephritis.

Pharmacokinetic and clinical studies on cefmenoxime (CMX) in neonates and infants were conducted. 1. CMX 20 mg/kg was administered by intravenous bolus injection to 6 neonates (with ages 2 to 20 days) and 5 infants (with ages 36 to 107 days) and its serum concentration and urinary excretion rates were determined. In the neonates, serum concentrations of CMX after intravenous administration reached peak levels of 48.2 to 90.7 micrograms/ml (mean 70.4 +/- 14.3 micrograms/ml) in 1/4 hour, then declined with half-lives of 1.27 to 5.19 hours (mean 2.28 +/- 1.56 hours), and were 3.6 to 16.9 micrograms/ml (mean 8.3 +/- 6.0 micrograms/ml) at 6 hours. In the infants, serum concentrations at 1/4 hour were 67.5 to 111.0 micrograms/ml (mean 95.5 +/- 18.0 micrograms/ml); half-lives were 0.64 to 0.94 hour (mean 0.81 +/- 0.13 hour); and the serum concentrations at 6 hours were 0.2 to 1.1 micrograms/ml (mean 0.7 +/- 0.4 micrograms/ml). Mean peak serum concentrations in the neonates tended to be lower than those in the infants, but higher than those in children. Regarding the age differences of serum concentrations due to age in the neonates, their peak levels tended to be lower in younger ones. Half-lives were shorter in older subjects and, in early infancy, approached values observed in children. Urinary recovery rates in the first 6 hours after intravenous administration ranged from 43.6 to 87.5% (mean 61.6 +/- 14.6%) in the neonates and from 52.1 to 90.8% (mean 78.0 +/- 15.1%) in the infants. Thus, recovery rates were high even in younger subjects and tended to be higher in older subjects. 2. CMX was administered to 27 neonates and 4 infants to investigate its clinical effect, bacteriological effect and side effects. Clinical efficacy ratings of the drug in 19 neonate cases that could be evaluated (1 with purulent meningitis, 2 with suspected septicemia, 1 with acute bronchitis, 12 with acute pneumonia, 1 with impetigo, 1 with periumbilical abscess and 1 with acute pyelonephritis) were "excellent" in 14 cases, "good" in 4, and "poor" in 1. The efficacy rate covering "excellent" and "good" was 94.7%. In 4 infants (2 with acute pneumonia, 1 with periumbilical abscess and 1 with acute pyelonephritis), "excellent" was obtained in 2 cases and "good" in 2 cases. Thus, all the cases showed "good" or higher ratings. Bacteriologically, 1 strain of Staphylococcus aureus and 3 strains of Escherichia coli in neonates were eradicated while, in infants, 1 strain of S. aureus persisted but 1 of E. coli was eradicated.(ABSTRACT TRUNCATED AT 400 WORDS)

On the basis of intensified surveillance in Finland we report the epidemiology of invasive Haemophilus influenzae type b disease based on 333 consecutive culture-proved cases recorded during 1985 and 1986. The annual incidence rate among children younger than 5 years of age was 52/100,000; 46% of patients had meningitis, 29% had epiglottitis and 25% had other forms of invasive disease. The median age of patients was 27 months, with 45% younger than 2 years of age. Meningitis and epiglottitis were found more often among boys than among girls, whereas the opposite was found among patients with other types of invasive disease (P = 0.015). Among the latter 68% of children with pneumonia or septicemia were 2 years or older compared with 32% of patients with arthritis, cellulitis or pyelonephritis (P = 0.009). These background data are essential for correct interpretation and application of results from trials with H. influenzae type b conjugate vaccines that are currently ongoing in Finland.

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.

The clinical activity of piperacillin was evaluated in 34 children (mean age: 8 years) presenting with severe infection (septicaemia, meningitis, bronchopneumonia, pyelonephritis). A bacteriological diagnosis was established in 24 cases. The mean duration of treatment was 11 days, and the mean dose 220 mg/kg/day administered in three injections. In 25 cases piperacillin was combined with another antibiotic, usually an aminoglycoside (20 cases). Clinical cure or improvement was obtained in 29 children (85%). Treatment was well tolerated, with only 2 cases of moderate blood eosinophilia. In view of these results the authors suggest that piperacillin could be used in children in two circumstances: severe infections caused by Gram-negative cocci or bacilli in children with cystic fibrosis or neutropenia, and against infections contracted in intensive care units, or in children with febrile leucopenia, combined with an aminoglycoside in the absence of, or pending bacteriological results.

Known since 1930, C-reactive protein is, as serum amyloid P component its similar, part of acute phase response proteins. Its principals properties are short half-life (6-8 h), great (within 6 hours) and high (X500) rate after injury. It activates the classical complement pathway, leading further to bacterial opsonization. Different biological methods for measurement are described: both nephelometric laser method, most sensible, and agglutination-latex method, most simple and quickest, are chosen. Studies showed us that CRP value is interesting for diagnosis of bacterial infections: among them neonates infections, peri-partum infections, meningitis, pyelonephritis, pancreatitis or peritonitis. CRP value determination seems to be useful also to hold on with patients who keep infectious peril, as in post chirurgical following, neutropenic induced patients. It seemed to be no use for CRP measurement in grafts following. Its rate in inflammatory diseases or myocardial infarcts is just mentioned. The author precognize more determinations of CRP: in emergency laboratories for diagnosis of bacterial infections (agglutination latex method) and in "routine" to follow up the infectious peril.

Trimethoprim-sulfamethoxazole continues to be a useful antibiotic for common outpatient problems such as urinary tract infections, prostatitis, acute exacerbations of chronic bronchitis, and acute otitis media as well as for serious infections of the hospitalized patient including Pneumocystis carinii pneumonia, acute pyelonephritis, and some forms of gram negative meningitis. The other sulfonamides have a limited role.

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.
