Listeria monocytogenes can cause sepsis and meningitis during the neonatal period. Six cases of early onset neonatal sepsis caused by Listeria monocytogenes are reported here. These cases were diagnosed in a private hospital at Santiago, Chile from December 1984 throughout November 1986. The incidence rate was 1.4 x 1,000 liveborns. Clinical findings included prematurity (6), meconium stained amniotic fluid (6), hepatomegaly (6), splenomegaly (6), maculopapular exanthem (4), anal prolapse (3) and meningitis (1). Additionally 5 patients developed respiratory distress and 4 required ventilatory support. Overall mortality was 50% (3/6). All deaths were related to respiratory failure and occurred during the first week of disease. All patients received ampicillin and amikacin early in the course of their infection. Listeriosis of the newborn infant might be preventable by prompt recognition and treatment of maternal infections. Since Listeria infection in pregnancy is usually mild and symptoms and signs are nonspecific, prevention may be difficult. Pregnant women with fever of no clear origin or with an influenza like syndrome should be screened for listeriosis with cultures from blood, vagina and cervix samples.

The production and consequences of the components of the state defined as 'clinically significant sepsis', as seen in patients undergoing intensive therapy--fever, shock, respiratory failure and multiple system failure--are complex. The syndrome is not necessarily accompanied by detectable bacteraemia; the effective management cannot wait upon positive blood cultures. Possibilities for more effective intervention include the use of monoclonal antibodies to endotoxin or to tumour necrosis factor, and of prostaglandins to alter the microcirculation. More refined definition of the severe sepsis syndrome will be required before these measures can be fully evaluated.

ARDS is a complex type of respiratory failure that usually is a complication of a catastrophic critical illness, such as shock. Mortality is high, especially in patients with septic shock and multisystem failure. Mortality often is related to complications of refractory hypoxemia. Identifying patients at risk for developing ARDS and early recognition of ARDS are important so that treatment can be initiated to prevent the potentially lethal consequences of refractory hypoxemia. The nurse has an important role in collaborating with the physician and respiratory therapist to support the patient's oxygenation, ventilation, and tissue oxygen delivery system. The nurse is responsible for performing highly sophisticated assessment of clinical and hemodynamic parameters to evaluate the effectiveness of therapy. A key role of the nurse is anticipating, recognizing, and reporting to the physician complications of hypoxemia and complications of therapy that can lead to sepsis, airway trauma, or failure of other organ systems.

That there are so many models of sepsis and septic shock is tacit evidence that none of them are perfect. Although sepsis presents in many forms clinically, most clinicians would probably agree that virtually all severely septic patients manifest respiratory failure and ventilator dependence. Furthermore, failure of organs other than the lungs typically occurs days to weeks after the onset of the septic process. Although early deaths occur commonly in some situations (e.g., meningococcemia, pneumococcal bacteremia in asplenic individuals, Gram-negative bacteremia in the setting of profound granulocytopenia), most deaths due to sepsis occur after a protracted course in an intensive care unit. Thus, for certain important experiments, there is a need for an animal model of severe chronic sepsis characterized by these features: persistent hypermetabolism, low systemic vascular resistance, respiratory failure severe enough to require mechanical ventilation, late (nonpulmonary) organ system failure, and death. Obviously, creation of such a model will require a major commitment of resources, because it will require, in essence, the creation of an animal intensive care unit. Nevertheless, we believe that progress in sepsis-related research would be substantially facilitated were such a model available. Even without such a model, progress will continue in this field. A wide variety of good animal models are already available to investigators. In the next decade, as new methods, such as the powerful tools of molecular biology, are applied to problems related to the sepsis syndrome, these models will be invaluable in improving our understanding of pathophysiology and in developing new and more effective approaches toward therapy.

A retrospective review of 61 patients with calculous cholangitis was carried out. There were 31 men and 30 women and their mean age was 75.8 years. All patients had abdominal pain, 87% had chills and fever, 65% had clinical jaundice, 23% were in shock, and 54% had positive blood cultures. Because intravenous hydration and antibiotics did not help, 33 patients underwent surgery, 25 patients underwent endoscopic papillotomy (EP), and three patients underwent percutaneous transhepatic drainage of the common bile duct (PTD). Morbidity in the surgery group included two wound infections, one respiratory failure, and one renal failure. Morbidity in the EP-PTD group was one case of arterial bleeding requiring surgery and one of pancreatitis treated conservatively. Two patients (6%) died in the surgery group, one of sepsis and the other of cardiorespiratory arrest. In the EP-PTD group nine patients (32%) died of sepsis and multisystem organ failure. These patients were considered too ill to undergo surgery and thus repeat EP-PTD was carried out. Cholangitis persisted, and retained common bile duct stones with sepsis was the cause of death. Thus when initial EP or PTD is unsuccessful, surgical exploration of the common bile duct should be carried out to control sepsis.

A comparative, prospective study was made of the incidence of infection in the lower airway (purulent tracheobronchitis and pneumonia) in long-term patients who were mechanically ventilated due to respiratory failure of noninfectious origin. Twenty-eight patients were randomly allocated into a study group (A, n = 13) in which a nonabsorbable paste containing 2% tobramycin, 2% amphotericin B, and 2% polymyxin E was administered locally to decontaminate the oropharynx, and a control group (B, n = 15) in which a paste without antibiotics was also applied to the oropharynx. We studied the effectiveness of the prophylactic technique in decontaminating the oropharynx and trachea of organisms potentially pathogenic for the respiratory system. Decontamination was successful in ten of 13 patients in group A vs. one of 15 patients in group B (p less than .001). The results demonstrated a lower rate of infection in the lower respiratory tract in the study group (three patients with tracheobronchitis and no pneumonias) than in the control group (three patients with tracheobronchitis and 11 with pneumonia), the difference between both being highly significant (p less than .001). Two (15%) patients in group B developed sepsis of pulmonary origin. None of the patients on prophylactic treatment developed this complication. Although the overall mortality was similar in both groups (group A, 30% vs. group B, 33%), we believe that infection contributed to a great extent to the death of two of five patients in group B. We conclude that nosocomial pneumonia, which is a frequent complication in critically ill patients on mechanical ventilation, could be prevented by local application of nonabsorbable antibiotics to the oropharynx.

Adult respiratory distress syndrome is an inflammatory disorder of the lung parenchyma that results in severe respiratory failure. It is associated with sepsis syndrome and multiple organ failure and may be mediated by a variety of substances, several of which have been discussed in this article. Because sepsis syndrome, ARDS, and multiple organ failure are associated with a high mortality rate that has not been reduced significantly by supportive treatment, a rationale exists for therapeutic intervention with agents that affect the inflammatory cascade. Several of these agents, notably corticosteroids and prostaglandin E1, have been shown to be of no benefit in humans despite laboratory and animal studies suggesting their utility. Other agents, including surfactant, antiendotoxin antibodies, and NSAIDs, are undergoing clinical trials and may prove to be effective. A third group, including anti-TNF antibodies and pentoxifylline, are of theoretical benefit but await clinical trials.

Recently MRSA occupies a prominent position in nosocomial infections. We experienced 9 cases of severe MRSA infections in our department during the 10 months from Apr. 1989 to Jan. 1990. We investigated the clinical background of them. THE RESULTS of studies were as followed: 1) All cases were inpatients. 2) All cases were considered to be compromised hosts. 3) In 7 cases many kinds of catheters and apparatuses were pre-indwelt . 4) In 8 cases over 2 kinds of antibiotics and in 7 cases 3rd generation cephems were pre-administered. 5) The 5 cases, who were selected for coagulase typing, all belonged to type II. 6) All cases had almost similar patterns of drug sensitivity and were resistant to large amounts of antibiotics. All cases had good sensitivity to minocycline. 7) THE RESULTS: 3 died of sepsis and respiratory failure and 6 were alive (MRSA strains were still isolated in 3 cases and were eradicated in the other 3 cases 1-4 months after the therapy was started).

Acute pancreatitis complicated by acute renal failure (ARF) requiring dialysis is a rare condition with a mortality rate of 80%. During the period 1977-1988 419 patients were admitted to our hospital because of ARF requiring dialysis. Fourteen (3%) had ARF caused by acute pancreatitis. Ten patients developed respiratory failure, eight patients circulatory failure, four hepatic failure, and one disseminated intravascular coagulation. Three patients had complicating septicemia and two gastrointestinal bleeding. Ten patients (71%) died. All patients with four or more organ failures besides the pancreatic failure died. Median time from start of symptoms until death was 28 days. Mortality in this series does not differ from that reported over the last 40 years. The need of multicenter trials for the purpose of improving prognosis is emphasized.

The clinical manifestations of septicemic melioidosis and other bacterial septicemia were studied at Srinagarind Hospital, Khon Kaen University. Forty-three cases of septicemic melioidosis and 68 non-melioidosis septicemia cases were analysed. By univariate analysis, the following clinical features are associated with septicemic melioidosis: male patients; age below 45 years; underlying diabetes mellitus or renal failure; pulmonary infection, impending respiratory failure and multiorgan involvement, while abdominal pain and urinary tract infection were more common in non-melioidosis septicemia. By using discriminant analysis and logistic regression, 3 features (diabetes mellitus, multiorgan involvement, and no abdominal pain or pulmonary infection) could discriminate the two groups with the accuracy of more than 85 per cent.
