Four adult patients had life-threatening soft-tissue infections of the neck. One had Hemophilus influenzae infection, one had Streptococcus pyogenes infection, and two had polymicrobial mixed aerobic and anaerobic infections. Three of the four patients died despite appropriate antimicrobial therapy and surgical intervention. These cases demonstrate the spectrum of serious soft-tissue infections of the neck in both the compromised and the uncompromised host. Soft-tissue infections of the neck may be necrotizing or nonnecrotizing. Cellulitis secondary to H. influenzae and beta-hemolytic streptococci is usually non-necrotizing, whereas necrotizing infections are caused most commonly by synergistic organisms. Potential complications include septic shock, disseminated intravascular coagulation, acute renal failure, adult respiratory distress syndrome, mediastinitis, and pericarditis. Early recognition with aggressive medical and surgical therapy is essential to reduce the mortality.

Ninety-five patients with severe community-acquired pneumonia (SCAP) who were > or = 65 years of age were studied prospectively. A definite pathogen was identified in 37 cases (38.9%) and was most commonly Streptococcus pneumoniae, Haemophilus influenzae, or another gram-negative bacillus. The overall death rate was 40%. Eighty-three patients required mechanical ventilation and 40 needed vasoactive drugs. Multivariate analysis showed that the risk of death was higher in cases involving rapid radiological spread (relative risk [RR] = 6.99; 95% confidence interval (95% CI) = 1.54-31.70), shock (RR = 6.70; 95% CI = 2.13-21.02), previous steroid treatment or immunosuppression (RR = 5.50; 95% CI = 0.77-39.10), acute renal failure (RR = 3.88; 95% CI = 1.30-11.59), or an APACHE II score of > 22 on admission (RR = 2.25; 95% CI = 0.73-6.95). We conclude that SCAP in elderly patients is associated with high mortality, but it is inappropriate to withhold intensive care on account of age. The presence of complications and the severity of illness at initial presentation were the major variables affecting outcome. Except for immunosuppression, comorbidities did not seem to influence outcome. Finally, our data reinforce the current American Thoracic Society guidelines concerning therapy for patients with SCAP.

Sepsis is often associated with a downward spiral through a spectrum of systemic inflammatory response syndrome (SIRS) culminating in organ failure and death. Here we present a 3-year-old girl with Hemophilus influenzae septic meningitis who developed SIRS and acute renal failure. In the initial stage, the patient showed uremia, cytopenia, disseminated intravascular coagulation, elevation of tissue enzyme and ferritin values, hemophagocytosis and overproduction of nitric oxide. The serum cytokine profile revealed increased levels of soluble interleukin (IL)-2 receptor, IL-6, IL-10 and tumor necrosis factor alpha. The patient responded positively to early and intensive interventions including antibiotics, repeated exchange transfusions, dexamethasone and high-dose gamma-globulin. The above laboratory abnormalities almost normalized with clinical improvement. We consider that SIRS was probably responsible for the sequence of events resulting in renal failure in this case, and suggest that renal failure should be included among the serious complications of SIRS associated with Hemophilus influenzae septic meningitis.
