Epiglottitis in pediatric patients is an infection caused by Haemophilus influenzae type b, which can lead rapidly to sepsis and an asphyxial death. In an effort to study the cause and clinical course of adult epiglottitis, eight serially hospitalized adult patients with supraglottitis over a ten-month period were prospectively evaluated, including a daily laryngeal examination. Although multiple anatomic sites in the larynx and oropharynx were inflamed, the epiglottis was often not the most involved area and was actually normal in one patient. Bacterial cultures were harvested from blood, the nasopharynx, the oropharynx, and the vallecula in all patients and the preepiglottic space in two patients. In no case was H influenzae demonstrated. No patient developed respiratory compromise. It was concluded that epiglottitis is an inaccurate description of this disorder and that this non-H influenzae adult variety of supraglottitis seemingly can follow a less pernicious course than the classically described infection.

Both Neisseria meningitidis and Haemophilus influenzae are important isolates recovered in blood cultures from septicemic children. Sodium polyanetholsulfonate is present in most blood culture media and can inhibit the growth of certain bacteria, including N. meningitidis. The addition of gelatin to blood culture media neutralizes this inhibition. The growth of H. influenzae is enhanced by specific growth factors such as hemin and NAD. The addition of gelatin and V-factor-analog (a proprietary supplement for enhancing the growth of H. influenzae) might have a positive effect on the yield and on the speed of detection of septicemia in children. To evaluate this possibility, we did 4,565 paired comparisons of blood cultured in BACTEC 6B (aerobic) medium with and without the addition of both 1.2% gelatin and V-factor-analog. More aerobic and facultative bacteria grew in the 6B than in the 6B-gelatin-V-factor-analog medium (P less than 0.01). Only seven isolates of Neisseria spp. were recovered during this study period, with the 6B medium performing as well as the supplemented medium. When microorganisms grew in both bottles, they did so at the same time except for H. influenzae and Candida albicans. H. influenzae was recovered earlier from the 6B-gelatin-V-factor-analog bottle (P less than 0.01), with a mean time to detection of 8.5 h compared with 15.9 h for the 6B bottle. C. albicans was recovered earlier from the 6B bottle (P less than 0.02), with a mean time to detection of 34.9 h compared with 71.6 h for the 6B-gelatin-V-factor-analog bottle. We conclude that the 6B medium in its present formulation is superior to bB supplemented with gelatin and V-factor-analog.

The Oxoid Signal (Oxoid U.S.A., Inc., Columbia, Md.) blood culture system is a newly described, innovative method for visually detecting growth of microorganisms (D. Sawney, S. Hinder, D. Swaine, and E.Y. Bridson, J. Clin. Pathol. 39:1259-1263, 1986). We did 5,999 paired comparisons of equal volumes (10 ml) of blood in the Oxoid Signal and BACTEC (Johnson Laboratories, Towson, Md.) radiometric blood culture systems at two university hospitals that use identical methods of obtaining and processing specimens. Overall, more microorganisms were detected in the BACTEC system (P less than 0.001), in particular, streptococci (P less than 0.01), fungi (P less than 0.001), and nonfermentative gram-negative rods, especially Acinetobacter species (P less than 0.001). Trends favoring the BACTEC system for detection of Pseudomonas aeruginosa, Haemophilus species, and Neisseria species were noted. There were no differences in the yield of staphylococci, members of the family Enterobacteriaceae, and anaerobic bacteria. When both systems detected sepsis, the BACTEC did so earlier (P less than 0.001). This advantage was most notable at 24 h (70% of BACTEC positives detected versus 48% of Oxoid positives). The proportion of positives detected after 48 h, however, was similar (BACTEC, 84%; Oxoid, 78%). Revisions in the Oxoid Signal system itself or in the processing of Oxoid bottles appear to be necessary to improve its performance in detecting certain microorganism groups, especially fungi.

Ceftriaxone treatment (50 to 80 mg/kg once daily) was given to 201 children between 1 month and 18 years of age. There were 201 serious bacterial infections, including epiglottitis, pneumonia, cellulitis, osteomyelitis, septic arthritis, pyelonephritis, sepsis, and meningitis. The common pathogens responsible for pediatric infections isolated from these patients included Haemophilus influenzae, Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, and Escherichia coli. The overall clinic cure rate was 94%. Ten patients were clinically improved but not cured. There were two clinical failures. Bacteriologic failure occurred in six patients. The overall bacteriologic cure rate was 97%. Twenty patients (10%) experienced adverse effects; none required discontinuation of therapy. The efficacy, safety, spectrum, and convenience of ceftriaxone monotherapy make this antimicrobial agent a candidate for the treatment of choice of selected serious pediatric infections.

Imipenem/cilastatin sodium (MK-0787/MK-0791) was evaluated for its safety, efficacy and pharmacokinetics in children. Thirty cases of bacterial infections were treated with MK-0787/MK-0791 at a daily dose of 40 to 222 mg/kg for 2.25 to 13 days. Clinical cure rate was 93% and bacteriological efficacy rate was 88%. Treated diseases included severe tonsillitis due to mixed anaerobic infections, pneumonia, sepsis, brain abscess and soft tissue infections. Two cases, one with periosteomyelitis due to methicillin-resistant S. aureus and the other with pulmonary abscess due to Haemophilus influenzae (other than type b), failed to respond to the MK-0787/MK-0791 therapy. The serum half-life of MK-0787 was 0.892 hour in children with normal renal functions. An episode of convulsions in a case of sepsis with bacterial croup and brain edema was considered to be associated with the MK-0787/MK-0791 therapy. From the present study, MK-0787/MK-0791 appears a safe and effective antibiotic when used in children with a variety of bacterial infections.

From August 1980 through July 1984, 19 neonates had sepsis due to Haemophilus influenzae. Onset of disease occurred within 48 hours after birth of all the neonates. One neonate was born at term and 18 were born prematurely, including seven neonates born before 28 weeks' gestation. Eight neonates and one fetus died, six of them within 24 hours of birth. Acute chorioamnionitis was present in the placentas. Those neonates with the most severe placental inflammation survived while all of those who died had moderate or only mild chorioamnionitis. Acute villitis was noted in the placentas of three neonates who died. Respiratory distress syndrome (in 15 neonates) and pneumonia (in 15 neonates) were noted in 18 liveborn patients. Nine mothers had fever, six of them with genitourinary infections and one with septicemia due to H influenzae. All isolates of H influenzae were submitted for serologic typing and none were typable. In 14 cases, isolates were biotyped yielding eight with biotype II, four with biotype III, and one each with biotypes IV and V. Neonatal sepsis due to nontypable H influenzae is now nearly as common as sepsis due to group B Streptococcus. Both organisms produce diseases with many features in common, especially fulminant courses with respiratory distress and pneumonia, and often have a fatal outcome.

This is a survey of 234 pediatric patients in whom staging laparotomy/splenectomy was carried out (1975 to 1981) in the course of the Intergroup Hodgkin's Disease in Childhood Study (IHDCS). Relapse has occurred in 44 of these patients, and 12 have died, 7 secondary to extension of lymphoma, 2 with herpes or pneumocystis infections, 2 with leukemia, and 1 from an unrelated accident. During the period of surveillance (mean 5.5 yr), five episodes of bacterial sepsis (positive blood cultures) have occurred, including two due to Streptococcus pneumoniae; and three, to Hemophilus influenzae. The former occurred in the small group of patients in this series who had not received the prescribed pneumococcal vaccination. No fatalities were associated with these septic episodes. Intestinal obstruction secondary to adhesions (benign) occurred in eight patients and was managed without intestinal resection or mortality. One patient required operative release of an obstructed ureter following laparotomy, and one, oophorectomy for an infarcted (transposed) ovary.

To study the incidence of shock in children in association with gram-negative bacillary (GNB) sepsis and Haemophilus influenzae type b sepsis, we reviewed all episodes of septicemia with those organisms in a 10-month period. GNB were isolated from 10.95% and H. influenzae b from 13.8% of the patients whose blood cultures yielded bacteria. Shock occurred in 12.5% of patients with sepsis caused by GNB and in 10.3% of those with H. influenzae b sepsis. Shock occurred more frequently in patients with H. influenzae b sepsis with meningitis (20.6%) and more commonly in those who had GNB sepsis without meningeal involvement (11.4%). GNB sepsis was associated with severe shock and caused death of three of the four patients. Only one of the five patients with shock caused by H. influenzae b had severe shock and died. The good outcome of patients with sepsis and shock caused by H. influenzae may be related to the health status before illness and prompt appropriate antibiotic therapy.

From 1976 to 1985, 27 adult invasive Haemophilus infections were observed at the University Medical Center in Lausanne. Only 5 cases (19%) were caused by Haemophilus influenzae type b, while 12 cases (44%) were due to Haemophilus species other than H. influenzae. Two out of 24 strains tested were ampicillin-resistant. The infections were meningitis in 8, pneumonia in 7, endocarditis in 5, sepsis of unknown origin in 4, epiglottitis in 2, and one gynecological infection. Except for the latter three patients, each case was associated with one or more underlying conditions. Seven patients died (26%), in three of whom death was directly related to the infectious process. This report and a review of the literature show that adult invasive Haemophilus infections are not uncommon and may be serious. Associated underlying diseases and advanced age are generally present. In contrast to infections occurring in children, invasive Haemophilus infections in adults are not restricted to encapsulated Haemophilus influenzae type b strains.
