One thousand nine hundred and fifty four autopsies performed at British Columbia's Children's Hospital during a 7-year period were reviewed to determine the causes of sudden unexpected natural death in the age group from birth to 17 years. Of the 126 cases found, the largest group, 86 cases, was sudden infant death syndrome (SIDS). Nine deaths were the result of infection: 4 cases of H. influenza meningitis, 2 cases of meningococcemia, 2 cases of acute epiglottitis, and 1 case of necrotizing tracheobronchitis. Epilepsy, ruptured AV malformations, and brain tumors combined to make up an equally large group of 9 cases. Cardiac lesions were the third largest group, 6 cases. The three groups that posed the most difficulty in assigning a cause of death were (a) the group that were like SIDS yet had other confounding features, (b) the group in which metabolic death was suspected but not proven, and (c) death in epilepsy.

Paranasal sinusitis is an important source of sepsis and morbidity in head injury victims and requires aggressive pursuit and therapy. Of 208 head-injured patients, 24 developed paranasal sinusitis. The Glasgow Coma Scale score of the sinusitis patients was 7.1 +/- 3.9. Nineteen patients were intubated nasotracheally, and five were intubated orally. Sinus air fluid levels, indicative of bleeding into the sinus, were seen on 17 initial computed tomographic scans. Maxillary sinus suppuration occurred in 23 patients; in 20 it was the initial sinus involved. Twenty-one patients developed polymicrobial sinusitis. Coexisting infections were common. In 15 patients with concurrent tracheobronchitis or pneumonia, organisms identical to those in sinus aspirations were recovered from the sputum. Seven patients had associated bacteremia. Meningitis in six patients shared a common pathogen with their sinusitis. Nonoperative management successfully resolved sinus infection in 19 cases. Five patients required open sinusotomy.

To study the possible predisposing factors, clinical features, molecular epidemiology, and factors affecting mortality associated with bacteremia due to Acinetobacter baumannii, we reviewed 87 episodes of A. baumannii bacteremia occurring in 79 patients hospitalized at 2 university tertiary care centers and 4 community-based hospitals during a recent 18-month period. Plasmid DNA analysis and analysis of genomic DNA with pulsed-field gel electrophoresis was performed to investigate possible epidemiologic relationship. All patients acquired their infections in the hospital, and no seasonal variation was observed. Among patients with A. baumannii bacteremia, 91% were hospitalized in an intensive care unit, 99% had indwelling vascular catheters, 81% received prior broad spectrum antimicrobial therapy, 70% were mechanically ventilated, and 47% had major surgical procedures. In 39 cases (45%) the infection was related to indwelling vascular access devices. Other infections included pneumonia (9%), tracheobronchitis (22%), meningitis (2%), and burn wound infections (4%). Septic shock occurred in 30% of patients. All isolates were multidrug resistant. Polymicrobial bacteremia was observed in 35% of cases. The crude mortality rate was 44%. Death was considered attributable to A. baumannii bacteremia in 15 (19%) patients. All patients with pneumonia as the primary site of infection died. Using multivariate analysis, we identified 3 independent predictors of mortality: the presence of a rapidly or ultimately fatal underlying disease (p = 0.0009), septic shock at the onset of bacteremia (p = 0.0013), and mechanical ventilation (p = 0.016). Epidemiologic typing revealed that 82 episodes were associated with different hospital outbreaks of infection, and only 7 episodes were due to epidemiologically unrelated strains.

Haemophilus influenzae (Hi) causes many clinical illnesses such as meningitis, bacteremia, epiglottitis, pneumonia, otitis media, sinusitis and tracheobronchitis. Before the introduction of the Haemophilus influenzae type b (Hib) conjugate vaccine in 1988, Hib caused more than 95 percent of invasive Hi disease in developed countries. Conjugate vaccines were licensed for use in children > or = 15 months of age in 1989 and for use in children > or = 2 months of age in 1990. During 1987-1995, the incidence of invasive Hi disease among children < 5 years of age decreased 96 percent in the United States. This report summarizes the trend in invasive disease caused by Hi among Oklahoma children < 5 years of age. The data represents cases reported to the OSDH as part of the infectious disease surveillance system. Invasive Hi disease has been reportable by law in Oklahoma since 1983.

Mycoplasma pneumoniae (M. pneumoniae) is one of the smallest free-living bacteria known. Along with other unique characteristics of this genus, it lacks the typical peptidoglycan cell wall of most eubacteria. Best known for causing tracheobronchitis and atypical pneumonia in humans, this pathogen also causes a number of extrapulmonary syndromes such as meningitis/encephalitis and arthritis. Recent studies also suggest that infection may be associated with chronic conditions such as asthma. Although the mechanisms of M. pneumoniae pathogenesis remain to be elucidated, one important component of M. pneumoniae infections is the induction of proinflammatory and other cytokines in both acute and chronic conditions. In this review, we survey the induction of cytokines by M. pneumoniae in different model systems, and we discuss the possible role of induced cytokines in M. pneumoniae pathogenesis.
