Round pneumonia: imaging findings in a large series of children. Pediatr Radiol 2007; 37:1235-40.

Abstract
BACKGROUND Although round pneumonia is a well-known clinical entity, there have been no large case reviews, with most knowledge based on case reports and small series from the 1960s and 1970s. OBJECTIVE To review the imaging findings of a large series of children with round pneumonia. MATERIALS AND METHODS A retrospective review of radiographic and CT findings in all children reported to have round pneumonia at a large children's hospital from 2000 to 2006 was performed. Children with underlying medical conditions were excluded. Epidemiologic characteristics, radiographic and CT findings, and follow-up imaging were reviewed. RESULTS The review identified 109 children (mean age 5 years, range 4 months to 19 years). Round pneumonias tended to be solitary 98% (107/109), have well-defined borders 70% (77/109), and be posteriorly located 83% (91/109), with the following lobar distribution: left lower lobe (36), right lower lobe (33), right upper lobe (28), left upper lobe (7), right middle lobe (4), and lingula (2). Round pneumonia tended to resolve on follow-up imaging (95%, 41/43) as compared to progression to lobar pneumonia (4.6%, 2/43). Three patients (2.6%, 3/112) originally suspected to have round pneumonia were later shown to have other diagnoses: cavitary necrosis in pneumonia (two) or pleural pseudocyst (one). CONCLUSION Round pneumonia occurs in young children (mean age 5 years), tends to be a solitary lesion, and is most commonly posteriorly located. Misdiagnosis of other pathology as round pneumonia is uncommon.

Abstract
Hematopoietic stem cell transplantation (HSCT) is the treatment of choice for many hematologic malignancies and nonmalignant disorders of bone marrow function. Pulmonary infections from bacterial, fungal, and viral organisms are a major cause of morbidity and mortality in patients after HSCT. The radiographic and high-resolution computed tomography (HRCT) findings of the different lower respiratory tract viral infections are quite similar. Findings of viral pneumonia on HRCT include small poorly defined centrilobular nodules and patchy, often bilateral, areas of peribronchial ground-glass opacity and consolidation. Air trapping may be present because of associated bronchiolitis. Interlobular septal thickening, bronchial wall thickening, and tree-in-bud opacities may also be present. Advanced viral pneumonia with diffuse alveolar damage is characterized by patchy or confluent consolidation and ground-glass opacities. Although nonspecific, in the correct clinical setting, these HRCT findings can help suggest the diagnosis of viral pneumonia in recipients of HSCT.

Abstract
To evaluate the role of BAL, CTB, and OLB in the management of pulmonary infiltrates in pediatric HSCT recipients, we conducted a retrospective review of clinical records of pediatric HSCT recipients. Data were analyzed using Chi-square for dichotomous and anova for continuous variables. Logistic regression was used to adjust confounding variables for diagnostic yield. Forty patients underwent 44 separate procedures. Infections were the prevailing cause of infiltrates with a positive diagnostic yield (96%). CTB and OLB were performed more often in patients with focal infiltrates compared with BAL (100%, 71% vs. 22%; p < 0.01). Adverse events were not significantly different across the three procedures. OLB more often yielded information that led to change in medical management (71% vs. 0%, 34%; p < 0.05) compared with CTB and BAL. Patients who had a positive diagnostic yield had no apparent survival advantage when compared with those in whom a procedure yielded no information. Logistic regression demonstrated that focal infiltrate was the only independently predictive variable for identifying a cause of pulmonary infiltrate. In conclusion, all three invasive diagnostic procedures were safe. Having a focal infiltrate was independently and significantly associated with having a positive diagnostic yield.

Abstract
During recent years, a rising incidence of invasive pulmonary aspergillosis (IPA) in non-neutropenic critically ill patients has been reported. Critically ill patients are prone to develop disturbances in immunoregulation during their stay in the ICU, which render them more vulnerable for fungal infections. Risk factors such as chronic obstructive pulmonary disease (COPD), prolonged use of steroids, advanced liver disease, chronic renal replacement therapy, near-drowning and diabetes mellitus have been described. Diagnosis of IPA may be difficult and obtaining histo- or cytopathological demonstration of the fungus in order to meet the gold standard for IPA is not always feasible in these patients. Laboratory markers used as a non-invasive diagnostic tool, such as the galactomannan antigen test (GM), 1,3-beta-glucan, and Aspergillus PCR, show varying results. Antifungal therapy might be considered in patients with persistent pulmonary infection who exhibit risk factors together with positive cultures or sequentially positive GM and Aspergillus PCR in serum, in whom voriconazole is the drug of choice. The benefit of combination antifungal therapy lacks sufficient evidence so far, but this treatment might be considered in patients with breakthrough infections or refractory disease.

Abstract
Much of the morbidity and mortality in chronic obstructive pulmonary disease relates to symptomatic deteriorations in respiratory health termed exacerbations. Exacerbations also are associated with changes in lung function and both airway and systemic inflammation. The most common causes of exacerbation are micro-organisms: respiratory viruses such as rhinovirus, and various bacterial species. This article reviews and discusses current understanding of the biology of exacerbations, considering the definition, epidemiology, etiology, and the nature and evolution of the changes in symptoms, lung function, and inflammation that characterize these important events.

Abstract
Toll-like receptors are key to pathogen recognition by a host and to the subsequent triggering of an innate immune response. Experimental and clinical evidence shows that defects in Toll-like receptors or in signaling pathways downstream from these receptors render hosts susceptible to various types of infection, including aspergillosis. Patients receiving an immunosuppressive regimen, including corticosteroid therapy or cytotoxic chemotherapy, are also susceptible to infections. Aspergillus fumigatus is an opportunistic pathogen that infects the lungs of immunosuppressed hosts. Here, we review the evidence that experimental inactivation of various Toll-like receptors and of their signaling pathways may worsen cases of invasive pulmonary aspergillosis. Moreover, the literature clearly indicates that the type of immunosuppression is very important, as it influences whether or not Toll-like receptors contribute to infection. The involvement of Toll-like receptors, based on the immunological status of the patient, should be considered if an immunosuppressive treatment must be administered.

Abstract
CONTEXT Pulmonary infections are common and often life-threatening in solid organ and stem cell transplant recipients. Understanding their pathology is critical to making improvements in care and survival as well as in surgical techniques, immunosuppression management, prophylaxis, and treatment. Pulmonary infections are particularly common and serious in the susceptible population of lung transplant recipients. OBJECTIVE To summarize recent updates in the field for opportunistic infections and some common pathogens, and to consider the role of the diagnostic pulmonary histopathologist as well as advances in molecular diagnosis. DATA SOURCES This work is based on a selected review of the relevant medical and scientific literature, with emphasis on lung transplantation experience gained during 2 decades of practice. CONCLUSIONS Pulmonary infections in transplant recipients present a diagnostic challenge and are a continuing source of mortality and morbidity despite improvement in prophylaxis and treatment. Accurate diagnosis requires multidisciplinary input from clinicians, radiologists, and pathology disciplines as well as complementary molecular methods.

Abstract
The aim of this study was to assess the diagnostic value and safety of thoracentesis in hematopoietic stem cell transplantation (HSCT) recipients. We identified all hospitalized HSCT recipients who underwent thoracentesis from 1998 to 2006. We collected patients' clinical characteristics, indications for thoracenstesis, the complications of the procedure, and the etiology of the pleural effusion. A total of 50 thoracentesis findings were analyzed. Twenty-six patients underwent allogeneic HSCT, while 24 patients underwent autologous HSCT. The main indications for performing thoracentesis were to rule out infection and document or diagnose malignancy. Pleural effusions were characterized as exudate in 33 patients (66%). A specific diagnosis based on the thoracentesis was made in 13 patients (26%). These were malignancy in nine patients, parapneumonic in three patients, and empyema in one patient. The only documented complication was pneumothorax in five patients. The presence of exudative effusion and underlying solid malignancy were associated with specific diagnosis by thoracentesis (p = 0.0001 and 0.013, respectively). In spite of the tendency of HSCT recipients to develop pulmonary infections, complex parapneumonic effusions are rarely diagnosed by thoracentesis. The rate of complications is comparable to other patient populations.

Abstract
PURPOSE To establish whether a relationship exists between computed tomography features of lung opacities in severely neutropenic patients and their Aspergillus or bacterial etiology. METHODS Computed tomography scans of 124 patients with lung opacities larger than 5 mm occurring during severe (neutrophils <500/mm) and prolonged (>7 d) neutropenia-induced by bone marrow transplantation and/or high-dose chemotherapy for hematologic malignancies-were reviewed. Invasive pulmonary aspergillosis or bacterial pneumonia were assessed by means of bronchoalveolar lavage, bronchial washing, trans-bronchial biopsy or (for bacteria only) blood cultures. Pulmonary opacities were classified as nodules or as consolidations. The presence of a perinodular ground-glass halo, the similarity of consolidations to a pulmonary infarction and the presence of cavitation (crescent-shaped or not) were recorded. RESULTS Invasive pulmonary aspergillosis was diagnosed in 68 patients; bacterial pneumonia in 56. Nodules (85) were more common than consolidations (39); their distribution among the patients with aspergillosis (52 nodules and 16 consolidations) and those with bacterial pneumonia (33 nodules and 23 consolidations) was even. Out of the 19 nodules surrounded by a halo 17 were due to aspergillosis. Nine consolidations (3 due to aspergillosis) were infarctionlike shaped. Cavitation appeared during 22/68 aspergillosis and 31/56 bacterial pneumonias; an air-crescent in 6 patients with aspergillosis and in 24 with bacterial pneumonia. CONCLUSIONS Although rare enough, the perinodular halo is highly specific for invasive aspergillosis. The nodular pattern of lung opacities, their similarity to a pulmonary infarction, the occurrence of cavitation and the air-crescent are not related to aspergillosis.

Abstract
Pulmonary complications are among the most common and serious sequelae seen in hematopoietic stem cell transplantation (HSCT) recipients. This two-part review addresses the incidence and impact of pulmonary complications in pediatric HSCT patients. In this first part we review the available data for the use of diagnostic modalities in this population, including flexible bronchoscopy with bronchoalveolar lavage (BAL) and open lung biopsy (OLB). We also review the many infectious pulmonary complications that may occur in pediatric HSCT recipients, utilizing the traditional chronologic divisions of neutropenic phase (0-30 days following HSCT), early phase (30-100 days), and late phase (>100 days).

Abstract
We assessed incidence and risk factors of cardiovascular events in 265 patients undergoing allogeneic hematopoietic stem-cell transplantation (HSCT) between 1980 and 2000 and who survived at least 2 years. Results were compared with a cohort of 145 patients treated during the same period with autologous HSCT. The median age of patients with allogeneic HSCT at last follow-up was 39 years, and median follow-up was 9 years. Eighteen (6.8%) patients after allogeneic and 3 (2.1%) patients after autologous HSCT experienced an arterial event. The cumulative incidence of first arterial event after allogeneic HSCT was 22.1% (95% CI, 12.0-40.9) at 25 years. The cumulative incidence 15 years after allogeneic HSCT was 7.5% as compared with 2.3% after autologous HSCT. Adjusting for age, risk of an arterial event was significantly higher after allogeneic HSCT (RR 6.92; P =.009). In multivariate analysis, allogeneic HSCT (RR: 14.5; P =.003), and at least 2 of 4 cardiovascular risk factors (hypertension, dyslipidemia, diabetes, obesity) (RR: 12.4; P =.02) were associated with a higher incidence of arterial events after HSCT. Thus, long-term survivors after allogeneic HSCT are at high risk for premature arterial vascular disease. HSCT might favor the emergence of established risk factors, such as hypertension, diabetes, and dyslipidemia.

Abstract
BACKGROUND/PURPOSE To evaluate the ICU mortality rate of mechanically ventilated hematopoietic stem cell transplantation (HSCT) recipients and to identify the factors that were associated with ICU mortality. The impact of surgical lung biopsy (SLB) in patients with unexplained pulmonary infiltrates was also evaluated. METHODS Forty-one mechanically ventilated HSCT recipients admitted to the ICU during the study period were enrolled. The medical records were reviewed and data at ICU admission were analyzed. Data were compared between ICU survivors and nonsurvivors. The pathologic findings of SLB and the resulting impact on treatment were analyzed. RESULTS Eight patients (19.5%) survived the ICU stay, and seven (17%) lived to hospital discharge. The most common etiologies of ICU mortality included bacterial pneumonia, cytomegalovirus pneumonia, diffuse alveolar hemorrhage, sepsis, and aspergillosis. The factors associated with higher mortality were older age when performing HSCT, older age at ICU admission, higher acute physiology and chronic health evaluation (APACHE) II score, shock, higher respiratory rate, and higher heart rate at the time of ICU admission. Ten patients underwent SLB which resulted in treatment changes in five of them. Three patients had complications of SLB and one patient died of complications. CONCLUSION The ICU mortality rate of mechanically ventilated HSCT recipients was high. Factors associated with ICU mortality were older age, high APACHE II score, presence of shock, and higher respiratory or heart rate at the time of ICU admission. SLB might provide specific diagnosis in HSCT recipients with unexplained pulmonary infiltrates and aid modification of treatment.

Abstract
Our purpose was to determine if total body irradiation (TBI) with lung dose reduction protects against subsequent radiation-induced deterioration in pulmonary function. Between July 1997 and August 2004, 181 consecutive patients with hematologic malignancies received fractionated TBI before allogeneic peripheral blood stem cell transplant. The first 89 patients were treated to a total dose of 13.6 Gy. Thereafter, total body dose was decreased to 12 Gy with lung dose reduction to 9 or 6 Gy. All patients underwent pulmonary function test evaluation before treatment, 90 days post-treatment, then annually. Median follow-up was 24.0 months. Eighty-nine patients were treated with lung shielding, and 92 without. At 1-year post transplant, there was a small but significant difference in lung volume measurements between patients with lung shielding and those without. This was not observed at the 2-year time point. When stratified by good (>100% predicted) or poor (</=100% predicted) baseline lung function, patients with poor function demonstrated protection at 1 year with lung shielding, while those with good initial lung function did not. TBI with or without lung dose reduction has a small but statistically significant effect on pulmonary function measured at 1 year but not 2 years post irradiation.

Abstract
We describe the clinical courses and outcomes of allogeneic hematopoietic stem cell transplantation-associated organizing pneumonia (HOP) observed in our institution over the past 20 years. Charts and chest radiographs of 603 allogeneic transplant recipients were retrospectively reviewed for HOP. In total, 12 cases of HOP were identified (2.0%) at a median interval of 148 days after transplantation (range, 53-475 days), presenting with low-grade fever, nonproductive cough and dyspnea at onset. Initial antibiotic treatment did not ameliorate symptoms, but most patients responded well to 0.5-1 mg/kg of prednisolone. HOP flare-up occurred after discontinuing treatment or while tapering doses in 9 of 12 patients, but responded to re-treatment with the initial dose of steroid. Although three patients died, no deaths were attributable to pulmonary failure. The remaining nine patients displayed no relapse of primary disease and 5-year survival rate was 74.1%. Clinical features of the 12 patients were similar in that all underwent irradiation-containing conditioning and most had a prior history of acute graft-versus-host disease (GVHD) and cytomegalovirus (CMV) infection. Furthermore, eight patients had active chronic GVHD at onset of HOP. These findings suggest that factors such as irradiation-containing regimens, previous CMV infection and allogeneic immune reaction may contribute to HOP occurrence.

Abstract
Observation-based early warning scoring systems (EWSS) have been developed to improve the outcome of critically ill patients by triggering early critical care intervention. To date, none of these scoring systems have been evaluated in cancer patients or stem cell transplant (SCT) recipients. The aim of this study was to validate 3 established EWSS (modified early warning score [MEWS], patient-at-risk score [PARS], and Leed's early warning score [LEWS]) in adult recipients of Allogeneic SCT (Allo-SCT) and to determine their usefulness at predicting survival. We retrospectively analyzed the physiologic observations during the initial admission of 43 Allo-SCT recipients. Respiratory dysfunction was the most common (40 patients, 93%) event. All 3 EWSS revealed high accuracy in predicting in-hospital survival. The cutoff level associated with a high risk of in-hospital mortality was 7. Of 8 patients with a LEWS = 7, 6 died during their initial admission, whereas no patient with a lower score died (specificity 95%, sensitivity 100%). Acute clinical deterioration during the initial admission appeared to have an adverse effect on overall survival: in-hospital survivors with a LEWS >3 during their admission had a shorter median survival than patients with LEWS < or = 3, P = .018. This is the first study to validate EWSS in Allo-SCT and demonstrate that these systems are highly predictive of in-hospital and overall survival.

Abstract
Data regarding the incidence of invasive aspergillosis (IA) in the intensive care unit (ICU) are scarce, and the incidence varies. An incidence of 5.8% in a medical ICU has been reported. The majority of patients did not have a hematological malignancy, and conditions such as chronic obstructive pulmonary disease and liver failure became recognized as risk factors. Diagnosis of IA remains difficult. Mechanical ventilation makes it difficult to interpret clinical signs, and radiological diagnoses are clouded by underlying lung pathologies. The significance of a positive respiratory culture result is greatly uncertain, because cultures of respiratory specimens have low sensitivity (50%) and specificity (20%-70%, depending on whether the patient is immunocompromised). The use of serologic markers has never been validated in an ICU population. Limited experience with the detection of galactomannan in bronchoalveolar lavage fluid specimens has yielded promising results. Because of a delay in the diagnosis of IA, the mortality rate exceeds 50%. Recently, our therapeutic armamentarium against IA has improved. Data concerning the safety and efficacy of new antifungal agents in the ICU setting, however, are lacking.

Abstract
Hematopoietic stem cell transplantation (HSCT) is being used increasingly in the treatment of malignant and nonmalignant diseases. The treatment modality has been proven effective but is not without risks. Studies consistently have identified the need for advanced supportive care (e.g., multiple organ dysfunction, vasopressor use, mechanical ventilation) as a negative prognostic indicator in patients who have received HSCT. Among patients who have received HSCT, 15%-40% require critical care monitoring or advanced support. Nurses on intensive care units can positively impact outcomes for transplant recipients when they possess the specialized skills to recognize and promptly intervene when transplant-related complications arise. This article will provide a basic overview of the HSCT process and outline the complications that may necessitate transfer to a higher level of care for specialized skills and equipment in the intensive care setting.

Abstract
Alcohol dependence (AD) and, more generally, alcohol use disorders (AUDs) predispose individuals to adverse consequences that extend beyond the expected damage from alcohol-direct toxicity. Research has shown that the relationship of alcohol use to health outcomes is complex, as is the etiology of AD, and that the individual and social costs of alcohol-related problems are increasing. We review advances in alcohol science that explore the role of alcohol consumption and patterns of drinking in a range of medically comorbid conditions. Although new knowledge can assist in the development of appropriate medical management strategies, AUDs account for an important percentage of the global burden of disease and require approaches that are not uniquely focused on the identification and treatment of AD.

Abstract
Pulmonary complications occur frequently after hematopoietic stem cell transplantation (HSCT) and account for considerable mortality when associated with respiratory failure. Bronchoalveolar lavage (BAL) is commonly used in the diagnostic evaluation of pulmonary infiltrates in HSCT patients. Although the yield of BAL is well established in this setting, the impact on outcome is controversial. In addition, respiratory failure in HSCT patients is associated with high mortality. To determine if positive BAL predicted less respiratory failure and better survival, a retrospective review (between 1992 and 1998) of all HSCT patients who had bronchoscopy with BAL as part of their diagnostic evaluation for new pulmonary infiltrates was performed. Twenty-one patients met the inclusion criteria. Eleven patients (52%) had a positive BAL, defined as the isolation of infectious microorganisms or pulmonary hemorrhage in the lavage specimen. Most of the positive findings were pathogenic organisms (bacterial, fungal, and viral). Respiratory failure (defined as need for both intubation and mechanical ventilation) occurred in 11 of 21 patients (52%)-8 of 11 (73%) who had positive BAL compared with 3 of 10 (30%) who had negative BAL (P = .09). The overall mortality rate was 11 of 21 patients (52%). All deaths except one occurred as a direct result of respiratory failure. Although this study confirmed the high mortality rate in HSCT patients with respiratory failure, the BAL results were not predictive of outcome.

Abstract
The definition of broncho-pulmonary aspergillosis infections in non-immunocompromised patients remains vague and a wide range of clinical, radiological and pathological entities have been described with a variety of names, i.e. simple aspergilloma, complex aspergilloma, semi-invasive aspergillosis, chronic necrotizing pulmonary aspergillosis, chronic cavitary and fibrosing pulmonary and pleural aspergillosis, pseudomembranous tracheobronchitis caused by Aspergillus, and invasive aspergillosis. However, these disease entities share common characteristics suggesting that they belong to the same group of pulmonary aspergillosis infectious disorders: 1- a specific diathesis responsible for the deterioration in local or systemic defenses against infection (alcohol, tobacco abuse, or diabetes); 2- an underlying bronchopulmonary disease responsible or not for the presence of a residual pleural or bronchopulmonary cavity (active tuberculosis or tuberculosis sequelae, bronchial dilatation, sarcoidosis, COPD); 3- generally, the prolonged use of low-dose oral or inhaled corticosteroids and 4- little or no vascular invasion, a granulomatous reaction and a low tendency for metastasis. There are no established treatment guidelines for broncho-pulmonary aspergillosis infection in non-immunocompromised patients, except for invasive aspergillosis. Bronchial artery embolization may stop hemoptysis in certain cases. Surgery is generally impossible because of impaired respiratory function or the severity of the comorbidity and when it is possible morbidity and mortality are very high. Numerous clinical cases and short retrospective series have reported the effect over time of the various antifungal agents available. Oral triazoles, i.e. itraconazole, and in particular voriconazole, appear to provide suitable treatment for broncho-pulmonary aspergillosis infections in non-immunocompromised patients.

Abstract
GOAL OF WORK The admission of patients with hematological disorders to the intensive care unit (ICU) involves a complex resource usage and may be associated with high mortality. The decision making to transfer a severely ill patient to the ICU, therefore, presents an ethical dilemma. We assessed both early and long-term outcomes in relation to clinical characteristics with the aim to facilitate clinical decision making. MATERIALS AND METHODS We performed a cohort study of hematological patients admitted to ICU at a university hospital. MAIN RESULTS During a 6-year period (1996-2001), 85 patients with a median age of 59 years were admitted to ICU. The majority of patients (88%) suffered from hematological malignancies. Major reasons for ICU admission were respiratory failure (41%) and septic shock/pre-shock (24%). The median duration of ICU admission was 2 (1-67) days. Crude in-ICU, 30-day, and 6-month mortality rates were 30, 49, and 62%, respectively. Overall 5-year survival rate was 20%, and 13 (15%) patients were alive at time of follow-up (median 7.4 years). Respiratory failure requiring ventilatory support and a high Acute Physiology and Chronic Health Evaluation II score was significantly correlated to high in-ICU mortality, but not to long-term outcome. Type of hematological malignancy, neutropenia, thrombocytopenia, bacteremia, prior administration of chemotherapy, age, or gender was not significantly associated with outcome. CONCLUSIONS The current study provides encouraging results on long-term post-ICU outcome also in elderly patients with hematological diseases. For a substantial proportion of critically ill hematological patients, a short time care at an ICU is lifesaving. These patients should be offered intensive care unless or until it is clear that there is little prospect of recovery from the acute illness or that the underlying malignancy cannot be controlled.

Abstract
Alveolar hemorrhage (AH) is a frequent, serious complication of hematopoietic stem cell transplantation (HSCT). To study the incidence of AH, its clinical course and outcomes in HSCT patients, a retrospective review of the records of all adult patients who underwent bronchoscopy between January 1, 2002 and December 31, 2004 was carried out and those who underwent bronchoscopy after HSCT identified. A total of 223 patients underwent bronchoscopy after HSCT for diffuse pulmonary infiltrates with respiratory compromise. Eighty-seven (39%) patients had AH. Of these, 53 had AH without any identified organism while 34 had an organism along with hemorrhage on bronchoalveolar lavage (BAL). Six-month survival rate of patients with AH was 38% (95% confidence interval: 27-48%). In 95 of the 223 patients, an organism was isolated from BAL. These patients had poor outcomes compared to patients in whom no organism was identified. Patients with both AH and an organism had the worst prognosis. Mortality of patients with AH is improving and long-term survival of patients with AH is feasible. Isolation of a microbial organism in BAL is a strong predictor of poor outcome.

Abstract
BACKGROUND Diffuse alveolar damage (DAD) is a relatively common histopathologic finding at autopsy, particularly in patients dying with ARDS, and can result from a variety of causes. The spectrum of causes and associated prognostic implications for DAD diagnosed by surgical lung biopsy are unclear. METHODS We identified 58 consecutive patients with DAD diagnosed by surgical lung biopsy over a 7-year period, January 1996 through December 2002. The presenting clinicoradiologic features, causes, and clinical course of these patients were studied. RESULTS The median age was 61 years, 48% were women, and 60% were immunocompromised. Ninety percent of patients fulfilled the criteria for ARDS at the time of surgical lung biopsy. Chest radiography demonstrated bilateral parenchymal infiltrates, while CT revealed predominantly ground-glass and consolidative opacities. Infections were the most common cause of DAD (22%). Other causes were noninfectious pulmonary complications of hematopoietic stem-cell or solid-organ transplantation (17%), connective tissue diseases (16%), acute exacerbation of idiopathic pulmonary fibrosis (12%), drugs (10%), and radiation therapy (2%). Twelve patients (21%) had acute interstitial pneumonia (ie, no identifiable cause or predisposing condition for DAD). Overall hospital mortality was 53%, with the highest mortality (86%) occurring among patients for whom DAD represented acute exacerbation of idiopathic pulmonary fibrosis. CONCLUSION Our study showed that infections and acute interstitial pneumonia are the most common causes of DAD diagnosed by surgical lung biopsy. Hospital mortality rate associated with DAD may vary depending on the underlying cause.

Abstract
This prospective study focused on risk factors and clinical outcome of pulmonary and cardiac late effects after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We prospectively evaluated 162 children by pulmonary function tests (PFTs) and cardiac shortening fraction (SF) before allo-HSCT and yearly up to the 5th year of follow-up. The 5-year cumulative incidence of lung and cardiac impairment was 35 (hazard rate=0.03) and 26% (hazard rate=0.06), respectively. Patients presenting abnormal PFTs and SF at last follow-up were 19 and 13%, respectively, with a median Lansky performance status of 90% (70-100). Chronic graft-versus-host disease (c-GVHD) was the major risk factor for reduced lung function in univariate (P=0.02) and multivariate analysis (P=0.02). Total body irradiation (TBI) alone and TBI together with pre-transplant anthracycline administration were significant risk factors for reduced cardiac function in univariate analysis, only (P=0.04 and 0.004, respectively). In conclusion, our prospective study demonstrates an asymptomatic post-allo-HSCT deterioration of pulmonary and cardiac function in some long-term survivors, who had been transplanted in childhood, and thus emphasizes the need for lifelong cardiopulmonary monitoring and the development of new strategies both to reduce pre-transplant cardiotoxic regimens and to treat more efficiently c-GVHD.

Abstract
An 89-year-old man was admitted to the hospital due to intermittent anterior chest wall pain for > 1 month. A chest radiograph obtained on November 9, 2004, demonstrated a mass with an irregular border, inside a thin-walled cavity, located in the superior segment of the left lower lobe. A chest CT scan revealed an irregular thin-walled cavity, 5.9 x 5.4 x 4 cm in size, with an air-crescent sign in the superior segment of the left lower lobe, and an intracavitary fungus ball-like mass. A bronchoscopic examination was performed, revealing only external compression of the left lower lobe bronchial lumen. Cultures from both the brushing cytology and brushing fungus specimens were negative. Since the patient was a heavy smoker and the chest radiograph obtained 23 months before had revealed no active pulmonary lesion, neoplastic growth was still highly suspected. Thus, an (18)F-fluoro-2-deoxyglucose positron emission tomography study was performed on November 25, and a mass with a slightly increased standard uptake value (3.17; cutoff value, 2.5) was found. He received a left lower lobe lobectomy on December 23, and a tumor with many septum-like structures connecting the surrounding pulmonary parenchymal tissue was found in the superior segment of the left lower lobe. The final pathologic diagnosis was adenocarcinoma of the lung (pT2N0M0). Thus, even though the chest radiograph and chest CT scan showed a typical air-crescent sign (ie, mass inside a cavity) favoring a mycetoma, the physician should still keep in mind that lung cancer may also unusually present in this way.

Abstract
BACKGROUND With the advent of new antifungal agents, the identification of a causative pathogen is crucial to guide the antifungal treatment of invasive mold infection. However, tissue cultures often fail to grow a fungal pathogen in cases of suspected mold infection. METHODS In a prospective multicenter study, we compared the results of histopathological analysis, culture, and 2 seminested polymerase chain reaction assays identifying Aspergillus species and Zygomycetes as causative agents of invasive mold infections using respiratory tract biopsy samples obtained from 56 immunocompromised patients who had suspected mold infection. RESULTS Mold hyphae were detected histopathologically in 27 (48%) of the tissue specimens. Hyphae corresponded to either aspergillosis (n=18) or zygomycosis (n=6) or could not be further specified (n=3). A mold was cultured from 14 of 18 samples with aspergillus hyphae, 2 of 6 samples with Zygomycetes hyphae, and 1 of 3 samples with unspecified hyphae. Polymerase chain reaction was superior to culture in detecting the infecting mold (26 of 27 samples vs. 17 of 27 samples, respectively; P=.006) from histopathologically positive samples. Genus or species identification by sequencing of the polymerase chain reaction products were in accordance with culture results in 16 of 18 culture-positive samples. Both polymerase chain reaction assays failed to detect fungal DNA in 1 sample that had unspecified hyphae and negative culture results. CONCLUSION The PCR assays offer a reliable etiologic diagnosis that is superior to culture in patients with proven invasive mold infection. This may improve patient management through tailored antifungal therapy when cultures fail to grow a pathogen.

Abstract
OBJECTIVE The impact of a contributive result of open-lung biopsy on the outcome of patients with acute respiratory distress syndrome (ARDS) has not been extensively investigated. The aim of this study was therefore to determine the rate of contributive open-lung biopsy and whether it improved the prognosis of ARDS patients. DESIGN Prospective study conducted during an 8-yr period. SETTING A 14-bed medico-surgical intensive care unit and a 12-bed medical intensive care unit from the same hospital. PATIENTS One hundred open-lung biopsies were performed in 100 patients presenting ARDS. INTERVENTIONS Open-lung biopsy was performed after > or = 5 days of evolution of ARDS when there was no improvement in the respiratory status despite negative microbiological samples cultures and potential indication for corticosteroid treatment. MEASUREMENTS AND MAIN RESULTS Ten patients presented a mechanical complication following open-lung biopsy (two pneumothoraces and eight moderate air leaks). The unique independent factor associated with this complication was the minute ventilation when open-lung biopsy was performed (odds ratio, 1.20; 95% confidence interval, 1.03-1.41; p = .02). Fibrosis was noted in 53 patients but was associated with an infection in 29 of these 53 patients (55%). A contributive result of open-lung biopsy (defined as the addition of a new drug) was noted in 78 patients. Simplified Acute Physiology Score II was the only independent predictive factor of a contributive open-lung biopsy (odds ratio, 0.96; 95% confidence interval, 0.92-0.99; p = .04). Survival was higher in patients with a contributive open-lung biopsy (67%) than in patients in whom open-lung biopsy results did not modify the treatment (14%) (p < .001). The factors predicting survival were a contributive result of open-lung biopsy, female gender, and the Organ System Failures score the day of open-lung biopsy. CONCLUSIONS The present study shows that open-lung biopsy provided a contributive result in 78% of ARDS patients with a negative bronchoalveolar lavage. Survival of ARDS patients improved when open-lung biopsy was contributive.

Abstract
This study presents the case of rapidly progressing pulmonary aspergillosis in a 47-year-old woman who had healed cavitations of pulmonary tuberculosis in the right upper lobe. She had been treated for pulmonary tuberculosis seven years prior to admission. The initial manifestations of the disease on admission included cough, dyspnea, hemoptysis, pulmonary infiltrate, and renal failure. As anti-myeloperoxidase anti-neutrophil cytoplasmic antibodies (MPO-ANCA) were positive, she was diagnosed with ANCA-associated vasculitis and treated with corticosteroids. This treatment resulted in remission of the vasculitis. However, she developed new pulmonary symptoms and an enlarged cavitary lesion associated with the rapid formation of a fungal, ball-shaped shadow that was serially observed by radiological analysis. Pulmonary resection was finally performed because of acute progressive respiratory failure due to massive recurrent hemoptysis. A subsequent pathological analysis revealed a mass of hyphae with acute-angle branching, features consistent with Aspergillus, within the cavitary lesion, and she was diagnosed with pulmonary aspergillosis. The rapid development of pulmonary aspergillosis associated with the formation of an Aspergillus mycetoma should be attributed to the loss of normal immune mechanisms due to immunosuppressive treatment.

Abstract
UNLABELLED This is the first study reporting the relationship between the development of bronchiolitis obliterans organizing pneumonia (BOOP) and human leukocyte antigen (HLA) in patients with bone marrow transplantation (BMT). The HLA B35 was significantly higher in patients with BOOP than in patients without BOOP after BMT (P = 0.0069). The HLA B35 is important as a host factor for the generation of BOOP after BMT. OBJECTIVE To assess the relationship between the development of BOOP after BMT and HLA. METHODS We retrospectively reviewed clinical features and chest computed tomographic scans in 64 patients who underwent allogeneic BMT between March 1990 and September 2004, and evaluated the relationship between HLA and development of BOOP. RESULTS Development of BOOP was between days 22 and 347 (mean, 114 days). The common computed tomographic findings consisted of patchy consolidation in subpleural and/or peribronchovascular distributions. Frequency of HLA B35 in patients with BOOP development after BMT was significantly higher than in patients without BOOP after BMT (P = 0.0069). There were no significant relationships between the others of this antigen and BOOP development. CONCLUSIONS Our results suggested that HLA B35 is an important host factor for the generation of BOOP after BMT.

Abstract
OBJECTIVE It is difficult to obtain sufficient material from pulmonary thin-walled cavitary lesions filled with air by conventional percutaneous aspiration biopsy in order to make a diagnosis. In these cases, we performed percutaneous needle washing (PNW) and ascertained the diagnostic significance of this method. MATERIALS AND METHODS PNW was performed on 27 patients with a pulmonary thin-walled cavitary lesion whose diagnosis could not be made by sputum and bronchoscopic examinations. Before centesis, the depth of the lesion was measured on CT scan. After the 22-gauge needle was inserted under X-ray fluoroscopic guidance, normal saline was injected into the cavity and aspirated. The aspirated material was examined cytologically and microbiologically. The procedure was carried out during one 30-second breath-holding. RESULTS Upon performing PNW on 27 patients, malignant cells were detected in 10 patients and a bacterial or fungal pathogen was detected in 9 other patients [Aspergillus (4), Mycobacterium (3), Staphylococcus (1), Streptococcus (1)]. The diagnoses of 16 of the 17 patients who were negative for malignant cells on PNW, were ascertained as benign disease during their clinical course including 3 patients who were diagnosed as (or suspected of) having infectious disease clinically, while the diagnosis of one case was unknown. Therefore, the diagnostic sensitivity of PNW for malignant diseases was 91% (10/11), while that for infectious diseases was 69% (9/13). Mild pneumothorax was the only complication of PNW (2 cases). CONCLUSION PNW may be an appropriate diagnostic procedure for pulmonary thin-walled cavitary lesions whose diagnosis can not be established by other techniques.

Abstract
The rising incidence of pulmonary aspergillosis is a major clinical concern. However, only a limited number of antifungal drugs are available in Japan that are effective for pulmonary Aspergillus infections. Micafungin (MCFG), a newly developed echinocandin family antifungal drug, has potent antifungal activity in vitro, but few reports detailing its clinical effectiveness have been published to date. A retrospective study was performed using data from nine patients (seven males and two females) with chronic invasive forms of pulmonary aspergillosis, who were treated with either MCFG alone or together with other antifungal drugs between April 2003 and March 2004. The overall efficacy of the treatments was evaluated in the terms of clinical, mycological, serological and radiological responses. The average age of the patients was 61.9 (20-83) years old. Four patients received only MCFG and the remaining five patients were treated with MCFG in combination with amphotericin B (AMB) only (1 patient), itraconazole (ITC) only (2 patients) or AMB backed up by ITC during AMB discontinuation periods (2 patients). The mean duration of MCFG administration was 59.2 (28-96) days. Overall, the treatment was judged to have been effective for seven of nine patients. No patient's condition deteriorated in response to treatment. Administration of MCFG alone was judged to have been effective in three of four patients. No notable adverse effects were documented during MCFG administration. These data suggest that MCFG may be an effective and safe antifungal drug for the treatment of chronic invasive forms of pulmonary aspergillosis.

Abstract
Within the hematologic therapy procedures, stem cell transplantation (SCT) represents the most extensive and invasive intervention. Those patients have certain risks for several bacterial, viral, as well as fungal infections during the different stages of transplantation. Especially in allogenic transplantation, discrimination of non-infectious, mostly immunologic complications like graft-versus-host reactions or VOD (veno-occlusive disease) is crucial, and often represents a therapeutic challenge. An adequate intensive care therapy of these patients can only be achieved with the knowledge of the specific complications of SCT. This review starts with an overview of the SCT stages with their corresponding infectious and noninfectious complications, followed by the discussion of organ specific pulmonary, renal, cardiac, gastrointestinal, hepatic and neurological complications of stem cell transplantation.

Abstract
This is the first case report of acute respiratory distress syndrome (ARDS) due to chronic necrotizing pulmonary aspergillosis (CNPA). This patient had pulmonary fibrosis of unknown etiology with a right upper bulla. The wall of the bulla became thicker with the surrounding lung infiltration and the patient suddenly developed severe respiratory failure. It is necessary to confirm the possibility that ARDS may occur in CNPA and that peripheral eosinophilia might forebode worsening of CNPA.
