We report an exceptional case of fulminant endophthalmitis after uncomplicated extracapsular cataract extraction with posterior chamber lens implantation. The first unusual finding was the causative organisms, group G streptococci. These organisms are commonly found as normal flora of the skin, pharynx and gastrointestinal tract. They are also well known as pathogens of neonatal sepsis, otitis media and pneumonia, but there are only three case reports describing a streptococcus G endophthalmitis. The second unusual finding was the delayed onset of the fulminant endophthalmitis, occurring later than 9 days after surgery. A retrospective analysis of 17 additional cases showed that endophthalmitis occurred either during the first 5 days after surgery or later than 35 days after surgery. If endophthalmitis developed shortly after surgery it progressed rapidly and with intense inflammation. The other cases showed more chronic inflammatory reaction. From the latter finding we conclude that long postoperative monitoring remains necessary even if at first no signs of intraocular inflammation are detectable.

A 68-year-old man with otitis media developed signs of disseminated intravasal coagulation (DIC) and shock. Beta-lactamase positive Branhamella catarrhalis grew in all blood cultures and in secretion from the middle ear. The patient was immunocompetent and previously healthy. Severe B. catarrhalis septicemia has so far mainly been described in immunocompromised patients, mostly children, but this report shows that it may occasionally occur in immunocompetent adults.

Haemophilus influenzae type b is responsible for an estimated 15,000 to 20,000 cases of meningitis per year in the United States, mainly in children 2 months to 5 years old. The mortality rate from meningitis due to H influenzae type b infections ranges from 5% to 10%. Despite antibiotic treatment, up to 35% of survivors have permanent neurologic sequelae. In addition to meningitis, H. influenzae type b is responsible for other invasive infections, including epiglottitis, septicemia, cellulitis, septic arthritis, osteomyelitis, pneumonia, pericarditis, and otitis media; approximately 30,000 cases H influenzae diseases occur annually in the United States. The diseases peak in incidence between 6 and 12 months of age, with almost one half of the cases occurring before 1 year of age. About 75% of disease caused by H influenzae type b occurs in children younger than 24 months old. The incidence of disease is higher in children of certain groups, including blacks, Hispanics, Eskimos and Native Americans, young children attending day-care facilities, patients with asplenia or antibody-deficiency syndromes, and children of lower socioeconomic status. There is considerable evidence that antibody to the capsular polysaccharide (polyribosylribitol-phosphate [PRP] of H influenzae type b is protective.(ABSTRACT TRUNCATED AT 250 WORDS)

For many years Branhamella catarrhalis was regarded as a non-pathogenic inhabitant of the respiratory tract. This article outlines the spectrum of B. catarrhalis disease in childhood and the extent of the evidence for a pathogenic role of the organism. B. catarrhalis is a rare etiologic agent in septicemia, meningitis, and other systemic illness in both apparently normal and immunocompromised infants and children. It is an unusual cause of ophthalmia neonatorum, but can be confused with Neisseria gonorrhoeae. Whether or not B. catarrhalis is acquired from the birth canal in these cases has not been established. B. catarrhalis is most common as a respiratory tract pathogen in children, including pneumonia, bacterial tracheitis, sinusitis, and otitis media. Since it is difficult to rigorously document pathogenicity of any bacterium in bronchopulmonary infections in children, it is probable that the spectrum of B. catarrhalis disease is wider than that reported to date. The evidence for pathogenicity in acute otitis media is more extensive than for other infections. Otitis media due to B. catarrhalis is clinically similar to that due to other pathogens. B. catarrhalis can be isolated in pure culture from the middle ear exudate and persists if there is no antibacterial treatment. Gram-negative intracellular and extracellular diplococci can be seen on smears of the inflammatory exudate. There is preliminary evidence that there is an antibody response in B. catarrhalis otitis media. B. catarrhalis has emerged as an important and common pathogen in neonates, infants, and children.

Sixty temporal bones of 30 stillborns and neonates who died of causes other than septicemia were examined by histopathologic methods for evidence of otitis media and persistence of mesenchymal tissue. The incidence of silent otitis media is 23.3% in this study. Mesenchymal tissue was observed in 6 temporal bones that showed evidence of otitis media. The role of mesenchymal tissue as a causative or immunologic factor, however, needs further evaluation.

Otitis media has been previously shown to be a source of sepsis in the pediatric intensive care unit; however, pneumatic otoscopy and other otologic instruments are not commonly used in the pediatric intensive care unit. We undertook a prospective study to determine the prevalence of otitis media, to assess the risk factors involved with the development of these nosocomial infections, and to identify the causative organisms. We conclude that otitis media is a common entity in the pediatric intensive care unit, that it is probably caused by prolonged dysfunction of the eustachian tube associated with oral and nasally-placed tubes and that the bacteriology reflects that of the hospital environment and not that of the community.

Secondary bacterial infection was studied on 231 children admitted with Respiratory Syncytial virus (RSV) infection in the 10 years since 1987. Of the 231 children, 56 (24.2%) had dual bacterial infection possibly due to secondary bacterial invasion. The diagnoses of bacterial disease were sepsis (2), pyothorax (2), pneumonias (41), otitis media (7), nasopharyngitis (2) and urinary tract infection (2). Dual bacterial infections were more frequent in infants and children over 6 months than in infants younger than 6 months. The main etiologic agents were Staphylococcus aureus and enteric gram-negatives in infants, and Haemophilus influenzae, Streptococcus pneumoniae, beta streptococci and Branhamella catarrhalis in children over 1 year. The incidence of secondary bacterial infection was compared according to the usage of antibiotics just before admission. Patients who had been administered with penicillins or macrolides before admission had a significantly higher percentage of secondary bacterial infection (21/56, 37.5%) than those of no previous antibiotic therapy (11/64, 17.2%, p less than 0.025). The results indicate that the RSV infection itself sometimes predisposes to secondary bacterial infections, but indiscriminate use of antibiotics further increases the risk of secondary bacterial infections.

Serum concentrations and urinary recovery rates of cefmenoxime (CMX) were determined in 41 mature and premature infants (with ages 0-24 days) after one shot intravenous injection of 10, 20 (1-hour intravenous drip infusion was also carried out) or 30 mg/kg for treatment and prophylaxis of various infections. Because the number of cases included was small, a comparison study was conducted by classifying them into 3 groups; 3 days or younger, 4 to 7 days, and 8 days or older, rather than dividing them into groups of mature and premature infants. Clinical evaluation was conducted in 7 male and 1 female cases 1 to 29 days old, whose diseases comprised 1 case each with septicemia, purulent otitis media and phlegmonous cellulitis, 3 with pneumonia and 2 with urinary tract infection. 1. Changes in serum concentrations and urinary recovery rates (1) Intravenous bolus injection of 10 mg/kg: Serum concentrations of the drug in the 3 age groups peaked at 28.9, 29.5 and 29.1 micrograms/ml, respectively, all at 30 minutes after the drug administration, and thereafter gradually declined. The mean level in the 3rd group was the lowest at 1.9 micrograms/ml at 6 hours. Average serum half-lives of CMX were shorter in older subjects, 3.0, 1.9 and 1.4 hours, respectively in the 3 groups. Urinary recovery rates were relatively high, 68.9 to 84.9% in the 3 cases examined during the first 6 hours, and 15.4 to 66.2% during the first 2 hours. (2) Intravenous bolus injection of 20 mg/kg: Serum concentrations of the drug in the 3 groups peaked at 65.2, 60.5 and 65.8 micrograms/ml, respectively, all at 30 minutes after the drug administration, with no significant differences noted among the groups. The levels gradually declined thereafter in all groups, but remained rather high at 20.1, 6.5 and 9.5 micrograms/ml, respectively, at 6 hours. Average serum half-lives of CMX were 3.5, 1.7 and 1.9 hours, respectively. The inversion of values obtained between the 2nd and 3rd groups appears to be attributable to that all of the 3rd group were premature infants, and the body weight of 2 cases of them were less than 2,000 g each. Urinary recovery rates ranged widely from 37.0 to 89.4% in the 4 cases examined during the first 6 hours. (3) One-hour intravenous drip infusion of 20 mg/kg: Serum concentrations of the drug in the 3 groups peaked at 57.7, 60.2 and 72.4 micrograms/ml, respectively, all at the termination of the drug infusion.(ABSTRACT TRUNCATED AT 400 WORDS)

A total of 82 patients involving 83 episodes of proven or presumed bacterial infection were treated with sulbactam/ampicillin. These included 36 cases of soft tissue infection or abscess, four cases of joint or bone infection, 20 cases of respiratory tract infection (17 cases of pneumonia, two of otitis media, and one of tonsillitis), 15 urinary tract infections, three cases of enterocolitis, one case of infective endocarditis, two cases of septicemia, and two of peritonitis. The causative pathogen was isolated in 48 cases (49 infections). These pathogens included Staphylococcus aureus 13 cases, Staphylococcus epidermidis one, Streptococcus pyogenes two, Streptococcus pneumoniae two, Viridans group streptococcus two, peptostreptococcus one, Haemophilus influenzae one, Escherichia coli 12, Enterobacter cloacae three, Proteus mirabilis one, Acinetobacter calcoaceticus one, Salmonella spp. two, Shigella sonnei one, Bacteroides fragilis one, and polymicrobial infections of various combinations in five cases. No bacterial pathogens were isolated in 34 infections, 14 cases of pneumonia and 15 soft tissue infections. Sulbactam/ampicillin was given by intravenous bolus in a dosage range of 75-450 mg/kg/day in four divided doses for variable periods of time depending on the type and severity of the infection. Of a total of 83 episodes of infections, 80 (96.4%) cases were either cured or improved. Bacteriologic eradication also occurred in 46 (93.9%) of 49 infections. Side effects were diarrhea in two patients, acute hemolytic anemia in one patient, and transient elevations in SGOT and leukopenia in one patient. Side effects disappeared upon completion of treatment. Sulbactam/ampicillin is a safe and effective antibiotic for the treatment of common pediatric infections.

Tympanocentesis is a procedure that can identify pathogenic organisms in otitis media. However, the clinical value of this diagnostic method in the management of infants who have sepsis has not been previously reported. Although otitis media is a significant source of sepsis in infants, tympanocentesis is not routinely employed in the work-up of infants with sepsis who have abnormal otoscopic findings. Charts of 40 consecutive infants who had sepsis and were undergoing tympanocentesis as part of their emergency room work-up were reviewed. Results of middle-ear aspirations from these infants, the bacteriology of middle-ear effusions, and the role of this information in their clinical management is presented. In 80% of these patients, clinical management was directly affected by tympanocentesis data. Tympanocentesis is a safe, effective diagnostic and therapeutic procedure with which otolaryngologists can provide important bacteriologic information to the pediatricians who are managing infants with sepsis.
