Two adults were admitted to the University Hospital of Geneva with acute Haemophilus influenzae type b epiglottitis. The disease was characterized by rapid progression of sore throat, upper dysphagia, fever and dyspnea. Acute upper airway obstruction required emergency tracheotomy in both cases. The patients recovered under ampicillin therapy. All the 100 cases from the literature for which clinical data were available have been analyzed:--Epiglottitis in adult is not exceptional.--Haemophilus influenzae type b is the most common infective organism documented, and was found in all positive blood cultures but one.--The typical presentation is severe sore throat, with upper dysphagia, fever and dyspnea.--Clinical course is rapid and serious, and acute respiratory distress develops in 57% of cases; overall mortality is 27%.--Emergency routine tracheotomy appears to be the most reliable treatment.

Uvulitis is an uncommonly reported disorder with the potential for significant morbidity. We describe three cases of uvulitis seen within a six month period in our emergency department. In two cases with respiratory distress, but without epiglottitis, Haemophilus influenzae was isolated from throat or blood cultures. The third case was associated with group A streptococcus tonsillitis and no respiratory compromise. Atypical presentations of upper airway infection with H. influenzae may be increasingly common.

The purpose of this study is to report 18 cases of membranous laryngotracheobronchitis (MLTB) and to review 143 published cases in order to accurately characterize the epidemiology, presentation, clinical course, treatment, and outcome of patients with this disorder. The male:female ratio was 2:1; mean age was four years. Most patients presented with acute onset of respiratory distress with fever, toxicity, and stridor after a prodrome of upper respiratory tract infection lasting a few days. White blood cell counts varied over a wide range, and blood culture results were rarely positive. Respiratory cultures commonly yielded Staphylococcus aureus or Haemophilus influenzae. Diagnosis was usually confirmed by airway radiographs or endoscopy. An artificial airway was required in 83% of patients. Complications included respiratory failure, toxic shock syndrome, anoxic encephalopathy, and death. MLTB is a serious, potentially fatal cause of acute infectious airway obstruction in infants and children that requires an organized approach to diagnosis and management.

We analyze 13 children between 1 and 3 years old (mean: 24.6 +/- 6.5 months), who were diagnosed (by direct or radiological examination) of epiglottitis. Seven were male. All of them had fever and respiratory distress. Six blood cultures (46%) were positive for Hemophilus Influenzae, and in 5 cases were resistant to beta-lactamases. Diagnose was made by radiology (70%) or by direct examination (30%). Five patients were not intubated (38%), with a favorable outcome. One died after a cardiorespiratory arrest due to self-extubation. We describe in this study our experience in the conservative treatment of epiglotitis, although initial nasotracheal intubation is the safest method for the management of this entity.

Two neonates with early onset respiratory illness were found to have Haemophilus influenzae septicaemia. One of them died. A review of the English literature showed that Haemophilus influenzae septicaemia is increasing in incidence. Almost all cases presented with respiratory distress in the first 2 days. Other associated features included meningitis, arthritis, conjunctivitis and cellulitis. The mortality, which averaged 52%, was high, especially in premature babies. The septicaemia was caused by ascending infection from the colonized maternal birth canal, and most cases were caused by nontypable strains of Haemophilus influenzae. Because of the occurrence of ampicillin or chloramphenicol resistance, a third generation cephalosporin is the treatment of choice for known cases of serious infection.

Sixteen bronchoalveolar lavages (BAL) were performed in 15 children with HIV1 seropositivity, 12 of them being infected by HIV1. BAL was performed during episodes of acute pneumonitis with respiratory distress (group I: three cases) or without severity (group II: five cases), or in the presence of asymptomatic radiological pulmonary abnormalities (group III: seven cases). A specific diagnosis of infection was obtained in five cases of acute pneumonitis and 12 micro-organisms were identified by BAL: three cytomegaloviruses, three respiratory syncytial viruses, two Pneumocytis carinii, one Haemophilus influenzae, one Herpes simplex virus type 1, one Escherichia coli and one group A streptococcus. In three cases two micro-organisms were simultaneously identified. Cytological examination showed a high proportion of polymorphonuclear leukocytes in cases of acute pneumonitis (group II) and alveolar lymphocytosis in clinically asymptomatic children with radiological pulmonary abnormalities (group III). BAL appears to be a reliable tool for the investigation of pulmonary infections in children with HIV1 seropositivity. In addition it has the advantage of revealing latent cytological abnormalities in these patients.

During the past decade an increasing incidence of neonatal septicaemia caused by non-encapsulated Haemophilus influenzae has been reported in both the USA and Europe. From the Danish county of Northern Jutland four cases are reported in premature infants. Respiratory distress and septicaemia were apparent within the first 12 hours after birth, and clinical findings were similar to early onset neonatal septicaemia caused by group B haemolytic streptococci or pneumococci. One neonate born at the 28th week of gestation died, and three other neonates of gestational age 30 to 34 weeks recovered. The non-encapsulated strains were sensitive to ampicillin and belonged to biotypes II, III, and V.

Bacterial tracheitis, previously referred to as nondiphtheritic laryngitis with marked exudate, was commonly discussed in pediatric textbooks before 1940. It seemed to disappear as a clinical entity after that time, but it has been recorded with increasing frequency in the pediatric literature since 1979. We describe eight new cases and review 110 previously described cases. The clinical course consists of a prodromal upper respiratory illness with stridor, fever, and a variable degree of respiratory distress. Unlike patients with croup, patients with bacterial tracheitis do not respond to aerosolized racemic epinephrine. Most patients require endotracheal intubation; some require tracheostomy. Reported complications include pneumonia, pneumothorax, formation of pseudomembranes, toxic shock syndrome, and cardiopulmonary arrest. Bacterial tracheitis is a secondary bacterial infection following a primary viral respiratory infection. The most common preceding viral infection is parainfluenza. Staphylococcus aureus and Haemophilus influenzae are the predominant causes of bacterial tracheitis. Secondary bacterial infection may occur as a result of tracheal mucosal injury or impairment of normal phagocytic function due to viral infection.

A retrospective study carried out from January 1981 through August 1988 identified nine cases of materno-fetal infections (Staphylococcus aureus, 1 case; Klebsiella pneumoniae, 3 cases; enterococcus, 3 cases; Hemophilus influenzae, 1 case; and Pneumococcus, 1 case) in six girls and three boys; four premature infants developed respiratory distress requiring mechanical ventilation. In four cases, maternal history found risk factors for infection. All patients developed circulatory failure and one had purulent meningitis. Diagnosis was confirmed upon recovery of the microorganism from a central sample in six cases; in three cases, only the peripheral cultures were positive but diagnosis was supported by the positive maternal history and by clinical findings. Bacterial species were not associated with specific clinical or biological features, but infections due to Hemophilus influenzae, Klebsiella pneumoniae and pneumococcus were particularly severe (two deaths and two infants with neurologic sequelae). In some studies, unusual microorganisms account for 46% of septicemias and 36% of purulent meningitis. Group D streptococci are the most common bacteria in this category and may account for 10% to 15% of early neonatal septicemias. Organism-specific features are analyzed on the basis of data from the literature. Concerning therapy, this epidemiologic aspect of materno-fetal infections complicates the choice of the initial antimicrobial agents; because third-generation cephalosporins are not effective on listeria and group D streptococci, we advocate more widespread use of the ureidopenicillins instead of ampicillin.

During a 27 month study seven nonserotypable strains of Haemophilus influenzae and two of Haemophilus parainfluenzae were isolated from nine neonates. Seven had early infection associated with respiratory distress or conjunctivitis; three had septicaemia one of whom died. The incidence of haemophilus septicaemia was 0.23 per 1000 live births.
