Retrospective, Observational Analysis on the Impact of SARS-CoV-2 Variant Omicron in Hospitalized Immunocompromised Patients in a German Hospital Network-The VISAGE Study.

Endemic SARS-CoV-2 infections still burden the healthcare system and represent a considerable threat to vulnerable patient cohorts, in particular immunocompromised (IC) patients. This study aimed to analyze the in-hospital outcome of IC patients with severe SARS-CoV-2 infection in Germany. This retrospective, observational study, analyzed administrative data from inpatient cases (n = 146,324) in 84 German Helios hospitals between 1 January 2022 and 31 December 2022 with regard to in-hospital outcome and health care burden in IC patients during the first 12 months of Omicron dominance. As the primary objective, in-hospital outcomes of patients with COVID-19-related severe acute respiratory infection (SARI) were analyzed by comparing patients with (n = 2037) and without IC diagnoses (n = 14,772). Secondary analyses were conducted on IC patients with (n = 2037) and without COVID-19-related SARI (n = 129,515). A severe in-hospital outcome as a composite endpoint was defined per the WHO definition if one of the following criteria were met: intensive care unit (ICU) treatment, mechanical ventilation (MV), or in-hospital death. In total, 12% of COVID-related SARI cases were IC patients, accounting for 15% of ICU admissions, 15% of MV use, and 16% of deaths, resulting in a higher prevalence of severe in-hospital courses in IC patients developing COVID-19-related SARI compared to non-IC patients (Odds Ratio, OR = 1.4, p < 0.001), based on higher in-hospital mortality (OR = 1.4, p < 0.001), increased need for ICU treatment (OR = 1.3, p < 0.001) and mechanical ventilation (OR = 1.2, p < 0.001). Among IC patients, COVID-19-related SARI profoundly increased the risk for severe courses (OR = 4.0, p < 0.001). Our findings highlight the vulnerability of IC patients to severe COVID-19. The persistently high prevalence of severe outcomes in these patients in the Omicron era emphasizes the necessity for continuous in-hospital risk assessment and monitoring of IC patients.

Validation of the CLIF-C OF Score and CLIF-C ACLF Score to Predict Transplant-Free Survival in Patients with Liver Cirrhosis and Concomitant Need for Intensive Care Unit Treatment.

Both the Chronic Liver Failure Consortium (CLIF-C) organ failure score (OFs) and the CLIF-C acute-on-chronic-liver failure (ACLF) score (ACLFs) were developed for risk stratification and to predict mortality in patients with liver cirrhosis and ACLF. However, studies validating the predictive ability of both scores in patients with liver cirrhosis and concomitant need for intensive care unit (ICU) treatment are scarce. The aim of the present study is to validate the predictive ability of the CLIF-C OFs and CLIF-C ACLFs regarding the rationale of ongoing ICU treatment and to investigate their predictive ability regarding 28-days (short-), 90-days (medium-), and 365-days (long-term) mortality in patients with liver cirrhosis treated in an ICU. Patients with liver cirrhosis and acute decompensation (AD) or ACLF and concomitant need for ICU treatment were retrospectively analyzed. Predictive factors for mortality, defined as transplant-free survival, were identified using multivariable regression analyses and the predictive ability of CLIF-C OFs, CLIF-C ACLFs, MELD score, and AD score (ADs) was assessed by determining the AUROC. Of 136 included patients, 19 patients presented with AD and 117 patients with ACLF at ICU admission. In multivariable regression analyses, CLIF-C OFs as well as CLIF-C ACLFs were independently associated with higher short-, medium-, and long-term mortality after adjusting for confounding variables. The predictive ability of the CLIF-C OFs in the total cohort in short-term was 0.687 (95% CI 0.599-0.774). In the subgroup of patients with ACLF, the respective AUROCs were 0.652 (95% CI 0.554-0.750) and 0.717 (95% CI 0.626-0.809) for the CLIF-C OFs and for the CLIF-C ACLFs, respectively. ADs performed well in the subgroup of patients without ACLF at ICU admission with an AUROC of 0.792 (95% CI 0.560-1.000). In the long-term, the AUROCs were 0.689 (95% Cl 0.581-0.796) and 0.675 (95% Cl 0.550-0.800) for CLIF-C OFs and CLIF-C ACLFs, respectively. The predictive ability of CLIF-C OFs and CLIF-C ACLFs was relatively low to predict short- and long-term mortality in patients with ACLF with concomitant need for ICU treatment. However, the CLIF-C ACLFs may have special merit in judging futility of further ICU treatment.

Repeated Lung Ultrasound versus Chest X-ray-Which One Predicts Better Clinical Outcome in COVID-19?

The purpose of this study was to evaluate whether changes in repeated lung ultrasound (LUS) or chest X-ray (CXR) of coronavirus disease 2019 (COVID-19) patients can predict the development of severe disease and the need for treatment in the intensive care unit (ICU). In this prospective monocentric study, COVID-19 patients received standardized LUS and CXR at day 1, 3 and 5. Scores for changes in LUS (LUS score) and CXR (RALE and M-RALE) were calculated and compared. Intra-class correlation was calculated for two readers of CXR and ROC analysis to evaluate the best discriminator for the need for ICU treatment. A total of 30 patients were analyzed, 26 patients with follow-up LUS and CXR. Increase in M-RALE between baseline and follow-up 1 was significantly higher in patients with need for ICU treatment in the further hospital stay (p = 0.008). Both RALE and M-RALE significantly correlated with LUS score (r = 0.5, p < 0.0001). ROC curves with need for ICU treatment as separator were not significantly different for changes in M-RALE (AUC: 0.87) and LUS score (AUC: 0.79), both being good discriminators. ICC was moderate for RALE (0.56) and substantial for M-RALE (0.74). The present study demonstrates that both follow-up LUS and CXR are powerful tools to track the evolution of COVID-19, and can be used equally as predictors for the need for ICU treatment.

Differences in characteristics and infection severity between odontogenic and other bacterial oro-naso-pharyngeal infections

BackgroundDifferent bacterial infections of the oro-naso-pharyngeal (ONP) region may progress and require hospital care. The present study clarified differences in infection characteristics between hospitalized patients with odontogenic infections (OIs) and other bacterial ONP infections. The specific aim was to evaluate clinical infection variables and infection severity according to infection aetiology, particularly regarding features of OIs compared with other ONPs.MethodsRecords of patients aged ≥16 years requiring hospital care for an acute bacterial ONP infection in the emergency units of Otorhinolaryngology or Oral and Maxillofacial Surgery at the Helsinki University Hospital (Helsinki, Finland) during 2019 were evaluated retrospectively. The main outcome variables were need for intensive care unit (ICU) treatment and length of hospital stay. The primary predictor variable was infection category, defined as OI or other ONP. The secondary predictor variable was specific ONP infection group. Additional predictor variables were primary clinical infection signs, infection parameters at hospital admission, and delay from beginning of symptoms to hospitalization. Explanatory variables were sex, age, current smoking, heavy alcohol use or substance abuse, and immunosuppressive disease, immunosuppressive medication, or both. Comparison of study groups was performed using Fisher’s exact test, student’s t-test, and Mann-Whitney U.ResultsA total of 415 patients with bacterial ONPs fulfilled the inclusion criteria. The most common infections were oropharyngeal (including peritonsillar, tonsillar, and parapharyngeal infections; 51%) followed by infections from the odontogenic origin (24%). Clinical features of OIs differed from other ONPs. Restricted mouth opening, skin redness, or facial or neck swelling (or both) were found significantly more often in OIs (p < 0.001). OIs required ICU care significantly more often than other ONPs (p < 0.001) and their hospital stay was longer (p = 0.017).ConclusionsInfections originating from the tonsillary and dental origin had the greatest need for hospitalization. Clinical features of OIs differed; the need for ICU treatment was more common and hospital stay was longer compared with other ONPs. Preventive care should be emphasized regarding OIs, and typical infection characteristics of ONP infection subgroups should be highlighted to achieve early and prompt diagnosis and treatment and to reduce hospitalization time.

Vitamins, supplements and COVID-19: a review of currently available evidence.

BackgroundIn the midst of the COVID-19 pandemic, there has been an information overload of health data (both accurate and inaccurate) available to the public. With vitamins and supplements being readily accessible, many have turned to using them in an effort to combat the virus. The purpose of this review was to analyse clinical trials regarding vitamins and supplements for the treatment of COVID-19 infections.MethodsArticles were identified through a literature search utilizing online databases and bibliographic review.ResultsA total of seven articles were identified for review. All articles evaluated the use of vitamins and supplements for the treatment of COVID-19. Drug therapies included oral vitamin D, intravenous and oral vitamin C, oral vitamin D/magnesium/vitamin B12, oral zinc, oral combination zinc/ascorbic acid, and intravenous alpha-lipoic acid. The end points of each study varied, including the Sequential Organ Failure Assessment score, mortality, rate of intensive care unit (ICU) admissions, negativity of COVID-19 tests, oxygen requirements, and symptom burden.ConclusionOf the vitamins and supplements that were studied, vitamin D presented the most promising data demonstrating significant decreases in oxygen requirements, need for ICU treatment, SARS-CoV-2 RNA test positivity, and mortality. All of these benefits were exhibited in hospitalized patients. Other vitamins and supplements that were evaluated in studies did not demonstrate any statistically significant benefits. Common shortcomings of the articles included generally small sample sizes, varying sites of study (which could determine the virus variant), a lack of standard of care as background therapy, and utilization of doses that were higher than standard.

Does the ICU Requirement Score allow the poisoned patient to be safely managed without admission to the intensive care unit? – a validation cohort study

Background The Intensive care unit (ICU) Requirement Score (IRS) has been defined as identifying poisoned patients on hospital admission who do not require ICU referral, in an effort to reduce health expenses. However, this score has been poorly validated. We aimed to evaluate the IRS in a large cohort of poisoned patients. Methods We performed a single-center retrospective cohort study. IRS was calculated using clinical parameters obtained on admission including age, systolic blood pressure, heart rate, Glasgow coma score, intoxication type, co-morbidities (i.e., arrhythmia, cirrhosis, and respiratory insufficiency), and the combination of the intoxication with another reason for ICU admission. We evaluated the ability of IRS < 6 determined on admission to predict the lack of need for ICU treatment, defined as the need for mechanical ventilation, vasopressors, and/or renal replacement therapy in the first 24 h post-admission and/or death during the hospital stay. This score was compared to the usual prognostic scores, i.e., SAPS II and III, SOFA score, and PSS. Results During the 10-year study period, 2,514 poisoned patients were admitted, 1,011 excluded as requiring ICU treatment on admission, and 1,503 included. Among these patients, 232 met the endpoint whereas only 23/510 patients with IRS < 6 (4.5%) presented the endpoint and one patient died. The area under the curve of the IRS ROC curve was 0.736 (95% confidence interval (CI), 0.702–0.770). The negative predictive value of IRS < 6 was 95% (95% CI, 93–97), sensitivity 89% (95% CI, 85–93), specificity 38% (95% CI, 36–41), and positive predictive value 21% (95% CI, 18–24). IRS performance was similar to those of the other tested scores, which are however not readily available on admission. Conclusion Our data demonstrate the excellent negative predictive value of the IRS, allowing the exclusion of ICU requirements for poisoned patients with IRS < 6. IRS usefulness should be confirmed based on a prospective multicenter cohort study before extensive routine use.

Diagnostic Significance of Serum Galectin-3 in Hospitalized Patients with COVID-19-A Preliminary Study.

Severe coronavirus disease 2019 (COVID-19) is associated with hyperinflammation leading to organ injury, including respiratory failure. Galectin-3 was implicated in innate immunological response to infections and in chronic fibrosis. The aim of our preliminary study was the assessment of the diagnostic utility of serum galectin-3 in patients with COVID-19. The prospective observational study included adult patients admitted with active COVID-19 and treated in tertiary hospital between June and July 2020. The diagnosis was confirmed by the quantitative detection of nucleic acid of severe acute respiratory syndrome coronavirus 2 in nasopharyngeal swabs. Galectin-3 was measured by enzyme immunoassay in serum samples obtained during the first five days of hospital stay. We included 70 patients aged 25 to 73 years; 90% had at least one comorbidity. During the hospital stay, 32.9% were diagnosed with COVID-19 pneumonia and 12.9% required treatment in the intensive care unit (ICU). Serum galectin-3 was significantly increased in patients who developed pneumonia, particularly those who required ICU admission. Positive correlations were found between galectin-3 and inflammatory markers (interleukin-6, C-reactive protein, ferritin, pentraxin-3), a marker of endothelial injury (soluble fms-like tyrosine kinase-1), and a range of tissue injury markers. Serum galectin-3 enabled the diagnosis of pneumonia with moderate diagnostic accuracy and the need for ICU treatment with high diagnostic accuracy. Our findings strengthen the hypothesis that galectin-3 may be involved in severe COVID-19. Further studies are planned to confirm the preliminary results and to verify possible associations of galectin-3 with long-term consequences of COVID-19, including pulmonary fibrosis.

Clinical and prognostic significance of emergency MRI findings in neck infections

ObjectivesDue to its superior soft-tissue contrast and ability to delineate abscesses, MRI has high diagnostic accuracy in neck infections. Whether MRI findings can predict the clinical course in these patients is unknown. The purpose of this study was to determine the clinical and prognostic significance of various MRI findings in emergency patients with acute neck infections.Materials and methodsWe retrospectively reviewed the 3-T MRI findings of 371 patients with acute neck infections from a 5-year period in a single tertiary emergency radiology department. We correlated various MRI findings, including retropharyngeal (RPE) and mediastinal edema (ME) and abscess diameter, to clinical findings and outcomes, such as the need for intensive care unit (ICU) treatment and length of hospital stay (LOS).ResultsA total of 201 out of 371 patients (54%) with neck infections showed evidence of RPE, and 81 out of 314 patients (26%) had ME. Both RPE (OR = 9.5, p < 0.001) and ME (OR = 5.3, p < 0.001) were more prevalent among the patients who required ICU treatment than among those who did not. In a multivariate analysis, C-reactive protein (CRP) levels, RPE, and maximal abscess diameter were independent predictors of the need for ICU treatment, and CRP, ME, and maximal abscess diameter were independent predictors of LOS.ConclusionIn patients with an acute neck infection that requires emergency imaging, RPE, ME, and abscess diameter, as shown by MRI, are significant predictors of a more severe illness.Key Points• Two hundred one out of 371 patients (54%) with neck infection showed evidence of retropharyngeal edema (RPE), and 81 out of 314 patients (26%) had mediastinal edema (ME).• Maximal abscess diameter, RPE, and C-reactive protein (CRP) were independent predictors of the need for intensive care unit (ICU) treatment, and maximal abscess diameter, ME, and CRP were independent predictors of length of hospital stay.• Prognostic significance of MRI findings was evident also while controlling for CRP values.

Annexin A1 as a potential prognostic biomarker for COVID-19 disease: Case-control study.

BackgroundAnnexin A1 (AnxA1) is an important endogenous glucocoticoid protein that contributes to the suppression of inflammation by limiting the production of neutrophil and pro‐inflammatory cytokines. This study aims to determine the clinical predictivity value of blood AnxA1 levels in patients with mild and severe–critical pneumonia induced by COVID‐19.MethodsThis study employed a prospective, case–control study design and was conducted at Ankara Training and Research hospital between 10 February 2021 and 15 March 2021. A total of 74 patients (42 of whom had moderate and 32 of whom had severe/critical cases of COVID‐19 disease according to World Health Organization guidelines) and 50 nonsymptomatic healthy volunteers participated in the study. Blood samples were taken from patients at the time of hospital admission, after which serum was isolated. Following the isolation of serum, AnxA1 levels were evaluated using the enzyme‐linked immunosorbent assay method.ResultsThe serum AnxA1 levels were measured as 25.5 (18.6‐38.6) ng/ml in the control group, 21.2 (14.7‐32) ng/ml in the moderate disease group, and 14.8 (9.7‐26.8) ng/ml in the severe/critical disease group. Serum AnxA1 levels were significantly lower in the severe/critical disease group compared with the control and moderate disease groups (P = .01 and P = .0001, respectively). Using receiver operating characteristic analysis, a larger area under the curve (AUC) for the serum AnxA1 levels of the control group (AUC = 0.715, 95% CI = 0.626‐0.803; P = .0001) was calculated compared with the COVID‐19 patient group for the diagnosis of COVID‐19 disease. The AnxA1 level was found to be 80% sensitive and 54.1% specific at a cut‐off level of 18.5 ng/ml for the diagnosis of COVID‐19 disease. Moreover, the AnxA1 level was found to be 69.8% sensitive and 58.1% specific at a cut‐off level of 17.2 ng/ml in predicting the need for intensive care unit (ICU) treatment.ConclusionAnxA1 levels may be a beneficial biomarker in the diagnosis of COVID‐19 pneumonia and in predicting the need for ICU treatment in patients with COVID‐19 pneumonia at the time of admission to the emergency department.

The presence of liver cirrhosis is a strong negative predictor ofsurvival for patients admitted to the intensive care unit - Cirrhosis in intensive care patients.

Liver cirrhosis is a systemic disease that substantially impacts the body's physiology, especially in advanced stages. Accordingly, the outcome of patients with cirrhosis requiring intensive care treatment is poor. We aimed to analyze the impact of cirrhosis on mortality of intensive care unit (ICU) patients compared to other frequent chronic diseases and conditions. In this retrospective study, patients admitted over three years to the ICU of the Department of Medicine of the University Hospital Frankfurt were included. Patients were matched for age, gender, pre-existing conditions, simplified acute physiology score (SAPS II), and therapeutic intervention scoring system (TISS). A total of 567 patients admitted to the ICU were included in the study; 99 (17.5 %) patients had liver cirrhosis. A total of 129 patients were included in the matched cohort for the sensitivity analysis. In-hospital mortality was higher in cirrhotic patients than non-cirrhotic patients (p < 0.0001) in the entire and matched cohort. Liver cirrhosis remained one of the strongest independent predictors of in-hospital mortality (entire cohort p = 0.001; matched cohort p = 0.03) along with dialysis and need for transfusion in the multivariate logistic regression analysis. Furthermore, in the cirrhotic group, the need for kidney replacement therapy (p < 0.001) and blood transfusion (p < 0.001) was significantly higher than in the non-cirrhotic group. CONCLUSIONS: In the presented study, liver cirrhosis was one of the strongest predictors of in-hospital mortality in patients needing intensive care treatment along with dialysis and the need for ventilation. Therefore, concerted efforts are needed to improve cirrhotic patients' outcomes, prevent disease progression, and avoid complications with the need for ICU treatment in the early stages of the disease.

Intensive Care Risk Estimation in COVID-19 Pneumonia Based on Clinical and Imaging Parameters: Experiences from the Munich Cohort.

The evolving dynamics of coronavirus disease 2019 (COVID-19) and the increasing infection numbers require diagnostic tools to identify patients at high risk for a severe disease course. Here we evaluate clinical and imaging parameters for estimating the need of intensive care unit (ICU) treatment. We collected clinical, laboratory and imaging data from 65 patients with confirmed COVID-19 infection based on polymerase chain reaction (PCR) testing. Two radiologists evaluated the severity of findings in computed tomography (CT) images on a scale from 1 (no characteristic signs of COVID-19) to 5 (confluent ground glass opacities in over 50% of the lung parenchyma). The volume of affected lung was quantified using commercially available software. Machine learning modelling was performed to estimate the risk for ICU treatment. Patients with a severe course of COVID-19 had significantly increased interleukin (IL)-6, C-reactive protein (CRP), and leukocyte counts and significantly decreased lymphocyte counts. The radiological severity grading was significantly increased in ICU patients. Multivariate random forest modelling showed a mean ± standard deviation sensitivity, specificity and accuracy of 0.72 ± 0.1, 0.86 ± 0.16 and 0.80 ± 0.1 and a receiver operating characteristic-area under curve (ROC-AUC) of 0.79 ± 0.1. The need for ICU treatment is independently associated with affected lung volume, radiological severity score, CRP, and IL-6.

Using a simplified pre-hospital 'MET' score to predict in-hospital care and outcomes.

Medical emergency team (MET) activation criteria serve as a predictor of serious adverse events on hospital wards and in the emergency department (ED). We aimed to determine whether in-hospital MET activation criteria would be useful in identifying patients at risk in pre-hospital care. The data were collected retrospectively from 610 adult patients treated by physician-staffed helicopter emergency medical services. Pre-hospital vital signs were compared with MET activation criteria and scored accordingly to receive a simplified pre-hospital 'MET' score. The primary outcome measure was hospital mortality. The secondary outcome measures were admission to intensive care unit and the length of ED stay, intensive care unit (ICU) stay and hospital stay. The simplified pre-hospital 'MET' score was also compared with Emergency Severity Index (ESI) used as a triage tool in ED. Higher simplified pre-hospital 'MET' scores were associated with hospital mortality (P<0.001), the need for ICU treatment (P<0.001) and a more urgent ESI class in the ED (P<0.001). Higher simplified pre-hospital 'MET' scores were associated with shorter stay in the ED (P<0.001), longer stay in the ICU (P<0.001) and longer hospital stay (P<0.001). A simplified pre-hospital 'MET' score was an independent predictor for hospital mortality (odds ratio 2.42, confidence interval 1.84 3.18, P<0.001), regardless of age or patient's previous overall physical health classified by American Society of Anesthesiologists physical status classification system. A simplified pre-hospital 'MET' score is a predictor for patient outcome and could serve as a risk assessment tool for the health care provider on-scene.

Infective endocarditis on ICU: risk factors, outcome and long-term follow-up.

To identify factors associated with short-term, intermediate and long-term outcome in patients with infective endocarditis (IE) and the need for treatment on intensive care unit (ICU). Retrospective analysis and long-term follow-up by questionnaire in the two medical ICUs of our university hospital. We conducted a retrospective analysis of all consecutive patients with IE and need for ICU treatment in our department between 2002 and 2009. All patients fulfilled the modified Duke criteria for definite diagnosis of IE. Data of 216 patients (aged 62 ± 14 years, 31 % female) were analyzed, 15.7 % of whom had prosthetic valve endocarditis. Infectious agent (IA) was identified in 74 % and surgery was performed in 57 %. 56 patients (24.9 %) died on ICU, 9 patients were sent to palliative care units and died several days later. During follow-up, another 44 patients died. Multivariate Cox-regression analysis identified the following independent risk factors: High initial SAPS II for 30d-, multiple organ failure and high maximum SAPS II for 100d- and high maximum leukocyte count for long-term mortality. Surgical intervention during ICU was an independent predictor of a better 30d outcome. In contrast to general IE populations, IA and the type of infected impaired valve are not main predictors of survival in critically ill IE-patients. Biomarker of acute infection and markers for severity of illness (scores and organ failure) are independent risk factors for mortality. The surgical clearance of infected valve, device or abscesses is an independent predictor of 30d outcome.

Frequency of Disturbed Defecation Pattern in Neurosurgical Critically Ill Patients and Influence on Intracranial Pressure and Intensive Care Treatment

Background: Inadequate bowel movement is a common problem in intensive care patients. Aim of this study was to quantify the frequency of disturbed defecation pattern in critical ill neurosurgical patients and examine the influence on intracranial pressure (ICP) and treatment on intensive care unit (ICU). Patients and Methods: Data were collected retrospectively during treatment on a neurosurgical ICU over a period of three years. Daily bowel movement was regarded to be sufficient when stool volume was more than 150 ml liquid or mushy stool or the patient produced enough formed stool. Patients were classified into group “adequate defecation” when no period of more than three consecutive days without sufficient bowel movement was seen during ICU treatment or into group “inadequate defecation” respectively. A third group was built with patients showing constipation on seven consecutive days or longer. Results: In a total of 73 recorded patients, 11 showed an adequate defecation pattern. Within the first ten days of ICU stay mean daily ICP values did not differ. However, patients with inadequate defecation had to be ventilated mechanically significantly longer (15,9 vs. 8,8 days) and had a significant longer need for ICU treatment (24,8 vs. 15,6 days). The mean cumulative dose of sedatives, sufentanil and norepinephrine was significantly higher in patients showing inadequate defecation. However, even long periods of constipation were not associated with a clinically relevant increase of ICP. Conclusion: Neurosurgical ICU patients often show constipation. This does not cause elevated ICP values compared to patients without constipation. Disturbed bowel movement is associated with higher dosage of analgosedation and vasopressor therapy. Patients without constipation have to be ventilated less long and can be discharged from ICU earlier.

The Role of Albumin Level and Blood Urea Nitrogen/ Albumin Ratio in Prediction of Prognosis of Community Acquired Pneuomonia

The Role of Albumin Level and Blood Urea Nitrogen/ Albumin Ratio in Prediction of Prognosis of Community Acquired Pneuomonia

Do modern conflicts create different medical needs?

Purposes This study involved analysis of ( a) type of injuries and medical services used by military casualties in 3 conflicts and ( b) medical needs of military and civilian casualties from the 2006 conflict. Basic Procedures Military casualties from 3 conflicts and military and civilian casualties from the 2006 conflict were analyzed. Casualties were compared in relation to type of injury, length of stay (LOS), and operating room use (ORU). Main Findings Hospital LOS of soldiers in many departments decreased while increasing in intensive care unit (ICU). Type of injuries sustained by civilians and military casualties differed significantly. More civilian casualties required admission to ICU. Civilian ORU was higher for orthopedic and otolaryngological procedures. Principal Conclusions Civilians are less well protected during military conflicts, therefore, more susceptible to certain kind of injuries. Civilian and military casualties during conflicts have different medical needs. Civilians have higher morbidity than soldiers, which result in an increased need for treatment in ICU.

A new diagnostic approach to the patient with severe pneumonia.

36 patients with severe community-acquired pneumonia, treated in an intensive care unit (ICU), were examined in a prospective study using a comprehensive diagnostic program to establish an early etiological diagnosis. The resulting prompt and adequate antimicrobial therapy may have decreased the number of fatal cases. Special emphasis was placed on the use of a method incorporating fiberoptic bronchoscopy, together with protected brush sampling and bronchial lavage. An etiological diagnosis was established in 81% (29/36) of the cases. This etiological diagnosis was established within 48-72 h in 53% (19/36) of the patients, S. pneumoniae being the most frequent agent found (12 patients). This information, however, was poorly utilized since in only 11/19 of these patients was the antimicrobial therapy changed from a broad-spectrum antibiotic to a more specific narrow spectrum agent. The overall mortality rate was 22% (8/36). 7/8 patients who died had compromising factors. Most deaths in community-acquired pneumonia are still associated with pneumococcal infection. We conclude that fiberoptic bronchoscopy with brush samples via a plugged double lumen catheter provides the least misleading information concerning the etiological agent in pneumonia; sampling should be done as soon as possible after admission to the hospital, ideally before the need for ICU treatment; factors other than prompt antimicrobial therapy may influence the outcome of severe community-acquired pneumonia.
