Because chronic alcohol abuse alters immune defenses and increases infection in adults, we tested the hypothesis that maternal alcohol use during pregnancy would increase the risk of sepsis in very low birth weight (VLBW) premature newborns. We performed a case-controlled analysis of VLBW newborns born at Grady Memorial Hospital (Atlanta, GA). Alcohol exposure, as the predictive variable, was assessed by maternal self-report. The outcome variables were early-onset and multiple late-onset sepsis. Univariate analysis with Fisher exact test and multivariate analysis with the use of binary logistic regression were performed. Early-onset sepsis was 15-fold higher in the alcohol-exposed group (n=20) compared with findings for the matched control group (n=168) [alcohol-exposed group, 10%, vs. control group, 0.6%: odds ratio (OR) 6.8 (95% confidence interval [CI], 2.7-17.1), P < or = .05]. Early-onset sepsis in the alcohol+cocaine-exposed group (n=64) did not differ from findings for the control group. The prevalence of multiple late-onset sepsis did not differ among the exposure groups. Logistic regression analysis, controlling for chorioamnionitis and premature prolonged rupture of membranes, demonstrated an independent, increased risk of early-onset sepsis with alcohol exposure [OR 16 (95% CI, 1.2-210), P < or = .05]. We conclude that alcohol exposure significantly increased the risk of early-onset sepsis in this group of VLBW newborns. The effects of maternal alcohol abuse during pregnancy on the risk of infection in the VLBW newborn require further analysis.

This author has personally carried out in excess of 700 major hepatic resections for tumor, and runs a unit with a current resection rate of 200 per year, yet uses no scientific tests designed to judge hepatic reserve. In our unit, we have an advantage in that we deal with a northern European population, with a low rate of viral hepatitis, although alcoholism is becoming an increasing feature within our practice and we are dealing with more elderly patients that in the past, and more who have undergone neoadjuvant chemotherapy. In these patients, there appear to be greater risks of postoperative sepsis and slower regeneration. Approximately 65% of our current resection practice is hemihepatectomy or more and the majority is trisectionectomy (extended hepatectomy) and bilateral resection work. Preoperative, operative, and postoperative factors affect the occurrence of postoperative hepatic failure and these aspects are considered. Case series studies are presented to illustrate the incidence of significant hepatic failure we have encountered.

This study of ventilated patients investigated pneumonia risk factors and outcome predictors in 476 episodes of pneumonia (48% community-acquired pneumonia, 24% hospital-acquired pneumonia, 28% ventilator-associated pneumonia) using a prospective survey in 14 intensive care units within Australia and New Zealand. For community acquired pneumonia, mortality increased with immunosuppression (OR 5.32, CI 95% 1.58-1799, P<0.01), clinical signs of consolidation (OR 2.43, CI 95% 1.09-5.44, P=0.03) and Sepsis-Related Organ Failure Assessment (SOFA) scores (OR 1.19, CI 95% 1.08-1.30, P<0.001) but improved if appropriate antibiotic changes were made within three days of intensive care unit admission (OR 0.42, CI 95% 0.20-0.86, P=0.02). For hospital-acquired pneumonia, immunosuppression (OR 6.98, CI 95% 1.16-42.2, P=0.03) and non-metastatic cancer (OR 3.78, CI 95% 1.20-11.93, P=0.02) were the principal mortality predictors. Alcoholism (OR 7.80, CI 95% 1.20-17.50, P<0.001), high SOFA scores (OR 1.44, CI 95% 1.20-1.75, P=0.001) and the isolation of "high risk" organisms including Pseudomonas aeruginosa, Acinetobacter spp, Stenotrophomonas spp and methicillin resistant Staphylococcus aureus (OR 4.79, CI 95% 1.43-16.03, P=0.01), were associated with increased mortality in ventilator-associated pneumonia. The use of non-invasive ventilation was independently protective against mortality for patients with community-acquired and hospital-acquired pneumonia (OR 0.35, CI 95% 0.18-0.68, P=0.002). Mortality was similar for patients requiring both invasive and non-invasive ventilation and non-invasive ventilation alone (21% compared with 20% respectively, P=0.56). Pneumonia risks and mortality predictors in Australian and New Zealand ICUs vary with pneumonia type. A history of alcoholism is a major risk factor for mortality in ventilator-associated pneumonia, greater in magnitude than the mortality effect of immunosuppression in hospital-acquired pneumonia or community-acquired pneumonia. Non-invasive ventilation is associated with reduced ICU mortality. Clinical signs of consolidation worsen, while rationalising antibiotic therapy within three days of ICU admission improves mortality for community-acquired pneumonia patients.

The annual incidences of severe sepsis in several industrialized nations have recently been reported to be 50-100 cases per 100,000 persons. These numbers exceed the estimated rates for other diseases that hold a heightened public awareness, including breast cancer and acquired immune deficiency syndrome. There are also sex and race differences in the incidence of sepsis. Men are more likely than women to develop sepsis, with a mean annual relative risk of 1.28. Nonwhites are nearly twice as likely to develop sepsis as whites. These race and sex disparities in the incidence of sepsis are likely explained by differences in a variety of factors, including the presence of comorbid conditions. For example, chronic alcohol abuse is associated with a persistent fever, delayed resolution of symptoms, increased rates of bacteremia, increased use of intensive care, prolonged duration of hospital stay, and increased cost of hospitalization for infected patients.

A 30-year-old woman with malnutrition due to alcoholism and eating disorders was found to have acute respiratory distress syndrome (ARDS) and sepsis due to severe Streptococcus pneumoniae pneumonia. S. pneumoniae was detected by an in vitro rapid immunochromatographic assay for S. pneumoniae antigen in urine on the day of admission and by blood culture 2 days after admission. Symptoms and laboratory findings improved after treatment with sivelestat sodium hydrate, antibiotics, and mechanical ventilation. Treatment with sivelestat sodium hydrate also decreased serum neutrophil elastase activity. This case demonstrates the usefulness of early treatment with sivelestat sodium hydrate in ARDS due to severe pneumonia.

Epidemiological evidence gathered only in the past decade reveals that alcohol abuse independently increases the risk of developing the acute respiratory distress syndrome by as much as three- to fourfold. Experimental models and clinical studies are beginning to elucidate the mechanisms underlying this previously unrecognized association and are revealing for the first time that chronic alcohol abuse causes discrete changes, particularly within the alveolar epithelium, that render the lung susceptible to acute edematous injury in response to sepsis, trauma, and other inflammatory insults. Recent studies in relevant animal models as well as in human subjects are identifying common mechanisms by which alcohol abuse targets both the alveolar epithelium and the alveolar macrophage, such that the risks for acute lung injury and pulmonary infections are inextricably linked. Specifically, chronic alcohol ingestion decreases the levels of the antioxidant glutathione within the alveolar space by as much as 80-90%, and, as a consequence, impairs alveolar epithelial surfactant production and barrier integrity, decreases alveolar macrophage function, and renders the lung susceptible to oxidant-mediated injury. These changes are often subclinical and may not manifest as detectable lung impairment until challenged by an acute insult such as sepsis or trauma. However, even otherwise healthy alcoholics have evidence of severe oxidant stress in the alveolar space that correlates with alveolar epithelial and macrophage dysfunction. This review focuses on the epidemiology and the pathophysiology of alcohol-induced lung dysfunction and discusses potential new treatments suggested by recent experimental findings.

Infectious muscle diseases have very different aetiologies. The viral myositides are proved by clinical and laboratory evidences in various etiologic settings (Influenza A and B, Coxsackie and HIV). The bacterial myositis was considered in the near past a tropical disease, but in our days with migration of people from South to North and the endemia of AIDS it became a problem of the "civilized" world. On the other hand, tuberculous endemia in Central-Eastern Europe, including Romania, results in quite high incidence of osteoarticular tuberculosis. In this section the authors take into consideration some clinical entities, such as psoas abscess, postanginal sepsis, beta-haemolytic streptococcus infection and that caused by Koch bacillus. Other rare musculoskeletal infections such as gas gangrene and non-clostridial anaerobic myonecrosis are also reviewed. Immune depression caused by underlying diseases, therapies, alcoholism or old age is often encountered. The parasitic aetiologies include infestations with Trichinella spiralis, Cysticercus cellulosae, Toxoplasma and Amoeba. The contribution of imagistic methods to diagnosis is emphasised. Ultrasonography associated with CT imaging are usually used, while MRI should be reserved for cases in which axial skeleton is involved. The management is based on appropriate antibiotic therapy and surgery.

The aim of this study was to assess mortality and sequellae within cases from Nationwide survey of community acquired meningitis and identify risk factors for inferior outcome. Risk factors such as underlying disease (diabetes mellitus, cancer, trauma, neonatal age, splenectomy, alcoholism, sepsis, other infections), etiology, clinical symptoms and outcome (death, improvement and cured after modifications of ATB therapy, cured without change of therapy, cured with neurologic sequellae) were recorded and analysed with univariate analysis (chi2 or t test for trends, CDC Atlanta 2004). Analysing risk factors for inferior outcome (death or cured with neurologic sequellae), we compared patients who died or survived with neurologic sequellae to all patients with community acquired bacterial meningitis. Univariate analysis showed that trauma (p<0.05), alcohol abuse (p<0.05), diabetes, S. aureus (p<0.05) and gram-negative etiology (A. baumannii, Ps. aeruginosa or Enterobacteriaceae) (36% vs. 11,9%, p<0.05) were predicting inferior outcome. Analysing risk factors for treatment failure (death or failed but cured after change of antibiotic treatment) prior sepsis (34.1% vs. 13.9%, p<0.01) and gram-negative etiology (25% vs. 11.9%, p<0.02) were statistically significant predictors of treatment failure. Neisseria meningitis had less failures (p<0.05). Concerning infection associated mortality again diabetes mellitus (p<0.05), alcoholism (p<0.05) staphylococcal and gram-negative etiology (p<0.05) were significant predictors of death. N. meningitis had surprisingly less treatment failures (appropriate and rapid initial therapy). Neurologic sequellae were more common in patients with alcohol abuse (p<0.05), craniocerbral trauma (p<0.05) and less common in meningitis with pneumococcal etiology (p<0.05).

The aim of this study was to assess if differences in etiology and risk factors among 372 cases of bacterial meningitis acquired after surgery (PM) or in community (CBM) have impact on outcome of infected patients. Among 372 cases of bacterial meningitis within last 17 years from 10 major Slovak hospitals, 171 were PM and 201 CBM. Etiology, risk factors such as underlying disease, cancer, diabetes alcoholism, surgery, VLBW, ENT infections, trauma, sepsis were recorded and mortality, survival with sequellae, therapy failure were compared in both groups. Significant differences in etiology and risk factors between both groups were reported. Those after neurosurgery had more frequently Coagulase negative staphylococci (p<0.001), Enterobacteriaceae (p=0.01) and Acinetobacter baumannii (p=0.0008) isolated from CSF and vice versa Streptococcus pneumoniae (p<0.001), Neisseria meningitis (p<0.001) and Haemophillus influenza (p=0.0009) were more commonly isolated from CSF in CBM. Neurosurgery (p<0.001), sepsis (p=0.006), VLBW neonates (p=0.00002) and cancer (p=0.0007) were more common in PM and alcohol abuse (p<0.001) as well as otitis/sinusitis (p<0.001) and Roma ethnic group (p=0.001) in CAM. Initial treatment success was significantly more frequently observed among CAM (p<0.001) but cure after modification was more common in PM (p=0.002). Therefore outcome in both groups was similar (14.6% vs. 12.4%, p=NS).

Within last 17 years we went through all charts of bacterial meningitis within our nationwide survey and among 372 cases we found 62 cases of MM, in 12 cases with meningococcal disease (with shock, petechial effusions or disseminated intravascular coagulation or digital gangrenes). MM was usually observed in young adults without any of investigated risk factors like neoplasia, ENT (ear, nose, throat) focuses, elderly age, sepsis, diabetes, alcoholism, trauma, neonatal VLBW etc. Trauma, diabetes mellitus, alcohol abuse and chronic sinusitis/otitis were significantly less frequently found as a risk factor for MM. Mortality was very low, only 4.8% and was lower than overall mortality in CBM (12.4%, NS). Also the proportion of neurologic sequellae (9.7%) and initial treatment failure (8.1%) were comparable or even lower. This positive outcome results are probably because all N. meningitis strains were susceptible to penicillin, chloramphenicol, cefotaxim, cotrimoxazol or ciprofloxacin. Other reason for low mortality was that most cases received oral antibiotic immediately, even before admission (50 of 62). 95.2% of cases survived, 90.3% without any transient neurological residual symptoms.
