Abstract
A correct, fast, reliable identification method is pivotal in nosocomial environments to guide treatment strategies, whereas misidentification might lead to treatment failure. For routine identifications the Vitek system and CHROMagar are widely used but not always reliable, especially now with an increasing number of new emerging fungal pathogens that need careful identification. Here we describe two cases of candidemia, due to Candida palmioleophila previously misidentified as Candida albicans by using the Vitek2 system and CHROMagar. The first case is a 54-year-old man with an infected ulcer in the lower right limb, treated with a targeted therapy using a central venous catheter (CVC). After two months he developed a CVC-related candidemia MDR identified as C. albicans. The second case is a 2-month-old male baby that was admitted to the neonatal unit with acute respiratory failure due to a severe community-acquired bilateral pneumonia; blood cultures were all positive for C. albicans MDR. The isolated strains where re-identified with Maldi-Tof and DNA sequencing as C. palmioleophila. From the identification point of view, CHROMagar can be clearly misleading, especially because CHROMagar types currently available are not designed to discriminate new emerging species, suggesting that systems other than MALDI-TOF and marker sequencing may be inadequate even for routine identification and could contribute to producing misleading identifications and therapeutically wrong practices, leading to failures and patient death.

Abstract
RATIONALE Actinomyces odontolyticus and Parvimonas micra are very rare causative organisms of lung abscess and acute respiratory failure. PATIENT CONCERNS A 49-year-old male patient visited the emergency room with a complaint of sudden onset of shortness of breath, and he developed acute respiratory failure rapidly. DIAGNOSIS An abscess in the left lower lung field was diagnosed on the computed tomography scan of chest. INTERVENTIONS Immediate treatment with intravenous antibiotics was initiated along with a pigtail catheter insertion for pus drainage. OUTCOMES A odontolyticus was cultured on the drained pus and P micra was identified by a blood culture. The patient was successfully weaned from the mechanical ventilator and the lung abscess was completely resolved. LESSONS To the best of our knowledge, this is the first case report of mixed infection with A odontolyticus and P micra, which caused acute respiratory failure in an immune-competent patient. Therefore, physicians should consider the possibility of these organisms as causative pathogens of a fulminant pulmonary infection even in an immune-competent patient.

Abstract
A 62-year-old man with diabetes mellitus and a two-day history of fever and dyspnea presented at our hospital. He was diagnosed with community-acquired pneumonia (CAP), septic shock, and respiratory failure. Sputum Gram staining revealed Gram-negative coccobacilli. Based on the Gram staining findings and history, Acinetobacter baumannii was considered as one of the causative organisms of his CAP. Consequently, he was successfully treated with the initial administration of meropenem. We suggest that A. baumannii should be considered as one of the possible causative organisms of CAP based on a fulminant clinical course, and the presence of Gram-negative coccobacilli.

Abstract
INTRODUCTION Severe fever with thrombocytopenia syndrome (SFTS) has been prevalent in parts of Asia during recent years. However, SFTS with invasive pulmonary aspergillosis (IPA) is rare, and it is important to understand its clinical features. MATERIALS AND METHODS Total four cases of SFTS with IPA are reviewed and detailing the disease progression, treatment options, and prognosis were summarized and analyzed. RESULTS The patients with SFTS-associated IPA first presented with fever, gastrointestinal symptoms, thrombocytopenia, leukopenia, and multiple organ failure. After 1-2 weeks, the patients developed mild polypnea and wheezing rales, and quickly developed dyspnea and respiratory failure. Tracheal intubation was usually performed, but did not relieve the intractable airway spasm and pulmonary ventilation failure. Bronchoscopy confirmed that the antifungal treatment was ineffective and the aspergillosis had worsened. All patients died of type 2 respiratory failure caused by continued airway obstruction and spasticity. CONCLUSIONS Given the high mortality rate in this series, there is a need for increased awareness of SFTS-associated IPA. Additional examinations should be performed in these cases, and early-stage antifungal treatment with organ support may be helpful.

Abstract
A previously healthy, 39-year-old obese farmer, arrived hypotensive and tachycardic, with fever, myalgia, headache, abdominal pain, diarrhea, and progressive dyspnea. Ten days before symptoms onset, he was in direct contact with mice and working in a contaminated drain. Patient laboratory showed acute kidney injury and thrombocytopenia. Chest X-ray exhibited bilateral diffuse interstitial infiltrates. First-line empirical antibiotics were started and influenza discarded. Patient evolved with severe respiratory failure, associated with hemoptysis, and rapidly severe hemodynamic compromise. Despite neuromuscular blockade and prone positioning, respiratory failure increased. Accordingly, veno-venous ECMO was initiated, with bilateral femoral extraction and jugular return. After ECMO connection, there was no significant improvement in oxygenation, and low pre-membrane saturations and low arterial PaO2 of the membrane showed that we were out of the limits of the rated flow. Thus, a second membrane oxygenator was installed in parallel. Afterward, oxygenation improved, with subsequent perfusion enhancement. Regarding etiology, due to high suspicion index, Leptospira serology was performed, coming back positive and meropenem was maintained. The patient ultimately recovered and experience excellent outcome. The clinical relevance of the case is the scared evidence of leptospirosis-associated severe respiratory failure treated with ECMO. This experience emphasizes the importance of an optimal support, which requires enough membrane surface and flow for an obese, highly hyperdynamic patient, during this reversible disease. A high index of suspicion is needed for an adequate diagnosis of leptospirosis to implement the correct treatment, particularly in the association of respiratory failure, pulmonary hemorrhage, and an epidemiological-related context.

Abstract
We report a case of a young individual who presented with fever and swelling of right upper and lower limbs for 3 weeks. Subsequently he developed shortness of breath and decreased urine output and had to be mechanically ventilated. Ultrasound screening of the lower limb had shown deep venous thrombosis (DVT) and thus the diagnosis of pulmonary thromboembolism (PTE) seemed probable. However the workup for PTE was negative and patient's fever continued and his condition deteriorated. Evaluation for an infective locus led to the diagnosis of pyomyositis and DVT appeared to have developed secondary to the muscle inflammation as a part of Reverse Lemierre's syndrome. Thus this case highlights the importance of considering this diagnosis in a similar setting and not to ascribe every case of respiratory failure in a background of DVT to be due to PTE.

Abstract
Nontuberculous mycobacteria (NTM) caused pulmonary disease is on increase worldwide, especially in countries with decreasing time trend of tuberculosis incidence. NTM skeletal affection is rare. Mycobacterium avium related disease, with still unclear clinical and radiologic features, is in current focus of both clinicians and researchers. An exhausted severely ill 71-year-old man was admitted on emergency due to cough, dyspnea and lumbar back pain to be diagnosed with terminal phase M. avium disease. Three sputum smears were positive for acid fast bacilli and M. avium was identified with hybridization reaction by means of GenoType ® MTBC (Hain). Apart from pulmonary disease, compressive fractures of the 12th thoracic and 1-4th lumbar vertebrae were detected. We found age, chronic alcoholism, previous professional exposure, tobacco smoking, chronic obstructive pulmonary disease and previous tuberculosis as risk factors for NTM disease in the HIV-negative patient. Despite combined antibiotic treatment, disease had lethal outcome. This case report might contribute to clinicians' awareness and improved knowledge on this sort of pathology, and lead to earlier diagnosis with possibly better disease outcome.

Abstract
In the last two years the Romanian adult population infected with the human immunodeficiency virus (HIV) has increased due to sexual transmission, both heterosexual and homosexual. The case presented is that of a 33 year-old man, admitted to the Infectious Diseases Hospital in Iasi with acute respiratory failure and a confirmation of Kaposi's sarcoma. Tests later proved positive for HIV, the patient being included in the stage AIDS C3 (acute immunodeficiency syndrome). The respiratory failure was suspected to be caused by Pneumocystis carinii and cotrimoxazol therapy, oxygen therapy and anti-retroviral therapy were established. He was also referred to the oncology hospital for treatment of Kaposi's sarcoma. The patient's adherence to therapy was influenced by a strong doctor-patient relationship, as well as by psychological counseling and support. Creating a functional doctor-patient-psychologist team is key throughout the HIV-positive patient's existence, for supporting long term adherence to therapy and acceptance of the diagnosis. This case highlights the need for a strong psychosocial compartment in every medical center that deals with HIV-infected individuals.

Abstract
Botulism is a severe neuroparalytic illness which is difficult to diagnose accurately, especially in children. We report a child with type A botulism intoxication, with very rapid progression to coma-like consciousness and respiratory failure. Careful physical examinations led to the suspicion of botulism, and electrophysiologic examinations, including electroencephalogram and repetitive nerve stimulation tests, further supported the diagnosis. Hospitalization due to botulism had a great emotional impact on the patient and psychological support was crucial.

Abstract
Legionella pneumophila is an agent also well known to be frequently responsible for severe community acquired pneumonia. Recent studies regarding severe community-acquired pneumonia have shown that Legionella pneumophila is the second most common cause of admission to ICU, not far behind pneumococcal pneumonia. The mortality of severe Legionella pneumonia is high (30%). We report two cases of severe respiratory failure due to Legionella pneumophila type 1 treated with non-invasive ventilation in the Respiratory Intermediate Care Unit of a Department of Respiratory Medicine with good outcomes. Severe community-acquired pneumonia is the most common cause of ARDS, and it is the primary reason for Intensive Care Unit admission with invasive mechanical ventilation. Delay in ICU admission is probably associated with a poorer outcome. The use of non-invasive ventilation in severe community acquired pneumonia is controversial. However, after recent pandemics, the number of studies reporting good rates of success for NIV has increased. Both our patients were managed in a respiratory intermediate care unit, avoiding invasive ventilation and invasive monitoring, which lowered costs yet was equally effective in providing a good outcome when compared to intubation in the Intensive Care Unit.

Abstract
BACKGROUND Tetanus is an infection that can be associated with a high mortality especially in developing countries. Critical care which may include artificial control of respiration is crucial in survival, but cardiovascular complications from autonomic instability remains an important cause of death. The objective of this report is to highlight this important cause of mortality despite artificial control of ventilation to prevent respiratory arrest. METHOD The medical record of the patient and relevant literature were reviewed. RESULT A 29-year old male following a wound on the lower limb presented with clinical features suggestive of tetanus. Incubation period was short and immunization history was uncertain. Basic treatment directed at removing source of infection and neutralisation of unbound toxin was however commenced. Following signs of imminent respiratory failure due to severe uncontrollable spasms, controlled mechanical ventilation was instituted in the critical care unit (CCU). However, the patient succumbed to cardiac arrest as a result of severe autonomic instability, despite aggressive cardiopulmonary resuscitation. CONCLUSION Cardiovascular arrest from severe autonomic instability remains an important cause of mortality in tetanus despite artificial ventilation. Early management with appropriate therapy is advisable to prevent its occurrence.

Abstract
Listeriosis is a rare food borne infection which, in the invasive form, presents as bloodstream infection, central nervous system infection, materno-fetal infection, or focal infection. Certain immunosuppressive conditions have been identified as risk factors for severe invasive disease. The invasive forms of listeriosis are associated with a high case fatality rate. We present the case of a 62-year-old male with an unremarkable medical history admitted to the Iasi Infectious Diseases Hospital for fever. headache, ataxia, and diplopia. Physical examination revealed high temperature, confusion, relative bradycardia, and signs of meningeal irritation. Laboratory test showed leukocyt osis with neutrophilia. pathological CSF findings (high WBC count with predominance of neutrophils, low glucose and high protein levels), increased liver enzymes (ALAT, ASAT, AP, gammaGT), and important renal impairment (normal levels at presentation). No abnormalities at chest x-ray, cranial CT and abdominal ultrasound. CSF and blood cultures were positive for Listeria monocytogenes. Under antibiotics (ampicillin and ciprofloxacin), the course was marked by respiratory failure requiring mechanical ventilation, coma, hypotension, tachycardia. and death 12 days after admission. The particularity of this case consists in the association of the two classical forms of invasive listeriosis, meningitis and bacteriemia, with a focal infection. acute hepatitis, and a course marked by multiple organ dysfunction syndromes and exitus in a previously apparently healthy individual.

Abstract
We report a case of a 27-year-old male who presented with respiratory distress that required mechanical ventilation. Transbronchial biopsy revealed adiaspores of the fungus Emmonsia crescens within granulomata, a condition known as adiaspiromycosis. The patient received amphotericin products and corticosteroids, followed by itraconazole, and made a full recovery. Emmonsia crescens is a saprobe with a wide distribution that is primarily a rodent pathogen. The clinical characteristics of the 20 cases of human pulmonary adiaspiromycosis reported since the last comprehensive case review in 1993 are described here, as well as other infections recently reported for the genus Emmonsia. Pulmonary adiaspiromycosis has been reported primarily in persons without underlying host factors and has a mild to severe course. It remains uncertain if the optimal management of severe pulmonary adiaspiromycosis is supportive or if should consist of antifungal treatment, corticosteroids, or a combination of the latter two. The classification of fungi currently in the genus Emmonsia has undergone considerable revision since their original description, including being grouped with the genus Chrysosporium at one time. Molecular genetics has clearly differentiated the genus Emmonsia from the Chrysosporium species. Nevertheless, there has been a persistent confusion in the literature regarding the clinical presentation of infection with fungi of these two genera; to clarify this matter, the reported cases of invasive Chrysosporium infections were reviewed. Invasive Chrysosporium infections typically occur in impaired hosts and can have a fatal course. Based on limited in vitro susceptibility data for Chrysosporium zonatum, amphotericin B is the most active drug, itraconazole susceptibility is strain-dependent, and fluconazole and 5-fluorocytosine are not active.

Abstract
Nocardia concava was identified as a new species in 2005; however, the clinical manifestations of Nocardia concava infection have yet to be clarified. We herein present the case of an immunosuppressed patient who developed disseminated nocardiosis caused by N. concava with multiple abscesses in the lungs, cutis, subcutaneous tissue, skeletal muscles and kidneys accompanied by central nervous system involvement, including meningitis and ventriculitis. The patient was cured with appropriate treatment including linezolid after testing for susceptibility. Linezolid should be considered as an alternative agent for treating disseminated nocardiosis because of its effective distribution to multiple sites.

Abstract
The paper describes 3 cases of ornithosis that could be detected by clinical and laboratory studies using immunological assays. In one case, its diagnosis was made late when the infection occurred in a woman working in a travel agency in Cyprus. The two other cases having an occupational contact (pet shop workers) were observed to have its acute form. All the described cases showed lung involvement characterized by external respiratory failure, one of the most common manifestations of ornithosis (psittacosis). Among the practically used laboratory tests, the indirect hemagglutination reaction is an accessible and effective serological assay for the diagnosis of ornithosis.

Abstract
BACKGROUND To describe the characteristics of patients with tuberculosis (TB) requiring intensive care and to identify the risk factors for mortality. METHODS We conducted a retrospective, cohort study, between January 2006 and December 2009. The patients with TB, admitted in Pneumology Clinic Hospital, Iasi, requiring advanced life support in intensive care unit (ICU), were included. We assessed different clinical parameters to identify the factors that predict in-hospital mortality. The primary outcome was the in-hospital mortality. RESULTS During the study period, 27 patients with TB required intensive care. Of them, 16 (59.3%) had acute respiratory failure and 6 (22.2%) required mechanical ventilation. Eighteen (66.7%) patients died. Acute respiratory failure, acute hepatic failure and mechanical ventilation significantly correlate with a high in-hospital mortality rate. CONCLUSIONS In this study we found a high mortality rate in TB patients requiring intensive care, identifying some risk factors.

Abstract
Haemolytic uraemic syndrome is an important cause of acute renal impairment in childhood. We review the incidence, and clinical and laboratory features of haemolytic uraemic syndrome in a Chinese population. Five patients were identified from 2006 to 2008. All patients were young children with associated invasive Streptococcus pneumoniae pulmonary infection. Serotypes 3, 14, and 19A were confirmed in four patients. The classical post-diarrhoeal form associated with Escherichia coli (O157:H7) infection was not seen. One patient died of acute respiratory failure. Streptococcus pneumoniae infection, as an associated condition in haemolytic uraemic syndrome, is important and relatively common in Chinese patients, especially among children. The acute clinical picture is similar to that reported in the western literature, except for an uncommon association with meningitis. The medium-term renal outcome of the Chinese population appears to be more favourable than the Caucasians. Widespread vaccination against Streptococcus pneumoniae may have resulted in changes in bacterial epidemiology and clinicians should be continuously aware of this severe disease. The use of washed blood components for transfusion in the acute stage requires further study.

Abstract
BACKGROUND Infection due to pandrug-resistant Pseudomonas aeruginosa (PDRPA) has become a challenge in clinical practice. The aim of this research was to summarize the treatment of large-area burns (60% - 80%) with PDRPA infection and respiratory failure in our hospital over the last two years, and to explore a feasible treatment protocol for such patients. METHODS We retrospectively analyzed the treatment of five patients with large-area burns accompanied by PDRPA infection and respiratory failure transferred to our hospital from burn units in hospitals in other Chinese cities from January 2008 to February 2010. Before PDRPA infection occurred, all five patients had open wounds with large areas of granulation because of the failure of surgery and dissolving of scar tissue; they had also undergone long-term administration of carbapenems. This therapy included ventilatory support, rigorous repair of wounds, and combined antibiotic therapy targeted at drug-resistance mechanisms, including carbapenems, ciprofloxacin, macrolide antibiotics and β-lactamase inhibitors. RESULTS Four patients recovered from burns and one died after therapy. CONCLUSIONS First, compromised immunity caused by delayed healing of burn wounds in patients with large-area burns and long-term administration of carbapenems may be the important factors in the initiation and progression of PDRPA infection. Second, if targeted at drug-resistance mechanisms, combined antibiotic therapy using carbapenems, ciprofloxacin, macrolide antibiotics and β-lactamase inhibitors could effectively control PDRPA infection. Third, although patients with large-area burns suffered respiratory failure and had high risks from anesthesia and surgery, only aggressive skin grafting with ventilatory support could control the infection and save lives. Patients may not be able to tolerate a long surgical procedure, so the duration of surgery should be minimized, and the frequency of surgery increased.

Abstract
OBJECTIVE To characterise the prognosis and identify factors contributing to mortality in patients with tuberculous destroyed lung (TDL). DESIGN Following a retrospective review of clinical data and radiographic findings, 169 patients with TDL were enrolled in this study. All patients were graded on a 4-point scale (field score 1-4) based on the extent of destroyed lung parenchyma on chest radiography. RESULTS The mean patient age was 64 years (range 33-90); 103 (61%) were male. The median number of hospitalisations was 1 (range 0-11) during follow-up, with a mean duration of 31 months (range 0-172). Pneumonia developed in 96 patients (57%), while 50 patients (30%) developed acute respiratory failure requiring mechanical ventilation, 37 (22%) haemoptysis, 24 (14%) spontaneous pneumothorax and 22 (13%) reactivation of tuberculosis. Overall mortality was 28% (47/169), with a median survival of 39 months (range 0-176) after diagnosis. TDL-related mortality was 19% (32/169), and a field score ≥ 3 was the only independent predictor of shorter survival based on a Cox proportional hazards model (HR 3.520, 95%CI 1.51-8.20, P = 0.004). CONCLUSION TDL has a poor prognosis, particularly in patients with more extensive lung destruction.

Abstract
PURPOSE Malignant pertussis is a rare life-threatening illness characterized by severe respiratory failure, severe leukocytosis, and pulmonary hypertension. The purpose of this study was to determine the prevalence of malignant pertussis in infants admitted to a pediatric intensive care unit (PICU) for severe acute respiratory failure associated with severe leukocytosis. METHODS This retrospective study was based on review of the medical charts of infants aged less than 3 months admitted to the PICU between 2006 and 2008 for severe acute respiratory failure requiring mechanical ventilation with leukocytosis greater than 50,000/mm3. Clinical and laboratory data were collected. Polymerase chain reaction (PCR) for detection of Bordetella pertussis was performed on nasopharyngeal washes (NPW) stored at -70 degrees C. RESULTS Ten patients meeting inclusion criteria were identified. Median age was 2.1 months (range, 0.6 - 3). None of the infants had been vaccinated against pertussis. Although PCR for pertussis was positive in all ten cases, presumptive diagnosis was made in only 3 patients during hospitalization. Nine patients died within a mean of 4.7 +/- 3.3 days after admission. The cause of death was refractory shock and hypoxemia in all cases. Only one patient survived. CONCLUSION Malignant pertussis is a severe disease that is almost always fatal. It was underdiagnosed in our PICU. Use of PCR for detection of B. pertussis, i.e., the reference method, should be promoted in developing countries.

Abstract
Bacillus anthracis, the causative agent of anthrax, is a category A priority pathogen that causes extensive damage in humans. For this reason, B. anthracis has been the focus of numerous studies using various animal models. In this study, we explored physiologic parameters in Dutch belted rabbits with inhalation anthrax to characterize the disease progression in this model. To this end, we infected Dutch belted rabbits with 100 LD(50) B. anthracis Ames spores by nasal instillation and continuously recorded various physiologic parameters by using telemetry. In addition, samples were collected at selected times for serum chemistry, hematology, and blood gas analysis. The animals exhibited hemodynamic and respiratory changes that coincided with those reported in human cases of inhalational anthrax infection, including hypotension, altered heart rate, and respiratory distress. Likewise, hematology, serum chemistry, and blood gas analysis revealed trends comparable to human anthrax-related pathophysiology. The Dutch belted rabbit model of inhalational anthrax exhibited most of the physiologic, hematologic, and biochemical sequelae noted in human cases. Therefore, this rabbit model fulfills several of the criteria of a useful animal model for studying disease pathogenesis and evaluating therapeutics during inhalational anthrax.

Abstract
In the last years an increasing number of subjects experienced respiratory failure and underwent tracheostomy. The aim of the present study was to analyze tracheal aspirates from the inflammatory point of view. Samples were collected from 38 consecutive tracheostomized patients: 13 COPD, 6 with neurologic disorders and 19 with other different causes of respiratory failure. We analyzed cells and soluble mediators related to inflammation and/or infection. We also compared results obtained in the tracheal aspirate of COPD patients with the same determination in the sputum of another group of non-tracheostomized COPD patients (n=41). Regardless of the underlying diagnosis, most of the samples were Pseudomonas aeruginosa positive and cells and soluble mediator did not differ. Treatment with steroids was associated with lower amount of total cells, neutrophils and lymphocytes, whereas treatment with antibiotics was not. Tracheal aspirate neutrophils correlated with PaCO(2) values; neutrophils and eosinophils correlated with their percentages in blood. As compared with sputa obtained from another group of culture-positive non-tracheostomized COPDs, tracheal aspirates showed similar cell count, proportions of inflammatory cells, and infection/inflammatory mediators. In conclusion tracheal aspirates presented high amounts of viable cells and soluble mediators independently to the cause of respiratory failure leading to tracheotomy and they represent suitable specimens to study infection/inflammation interactions.

Abstract
PURPOSE OF REVIEW The severe acute respiratory syndrome epidemic of 2002-2003, recent natural catastrophes, burgeoning concerns regarding intentional catastrophes, and the looming threat of an influenza pandemic have focused attention on large-scale, survivable respiratory failure. In this article, we review appropriate medical equipment, treatment space, and strategies to augment health professional staff in response to a massive increase in need for sustained critical care. RECENT FINDINGS There is insufficient modern healthcare experience with mass casualty respiratory failure to develop evidence-based preparedness efforts. For this reason, initial efforts to augment critical care capability in response to disasters have relied on extrapolation from the routine critical care knowledge base, military medicine, critical care transport, and expert opinion. We review recently published documents on augmenting supplies of positive pressure ventilation equipment, ongoing projects for increasing health professional staff, and infection control issues during epidemics. SUMMARY Mass casualty respiratory failure remains a largely unstudied field, but we believe informed decisions about equipment stockpiling and use, the development of creative operational concepts to increase staffing, and the careful implementation of rational infection control practices can lay a foundation for an appropriate response until additional data become available.

Abstract
The authors have drawn attention to a rare disease called infant botulism, which raises some difficulties with regard to differential diagnosis. In the case of the six-month-old infant portrayed, infant botulism and food-born botulism appeared together. As a result of the severity of the disease and due to its rapid course observed in the presented case as well, the diagnosis has to be raised relying on the accurate patient's history and on the clinical examination, then it should be confirmed by appropriate examinations. In relation to presenting a case, the authors examine the microbiological background of the disease, its symptomatology, its epidemiological characteristics, the appropriate methods of electrophysiological examination and laboratory analysis as recommended in current literature, together with the difficulties that arise in differential diagnosis and also the possibilities of treatment. They pay special attention to the particular characteristics of the infant form of the disease, to the difficulties of making a diagnosis due to the characteristics of the age group and also to the questions in relation to the guiding principles of therapy. The rapid and fatal process observed in the presented case warns us that serious complications can occur even when up-to-date therapy is used. Therefore, despite the improvement in prognosis we have to strive to prevent the disease by spreading the proper regulations of nutritional hygiene.

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
INTRODUCTION Intravesical bacillus Calmette-Guerin (BCG) therapy, recommended for superficial bladder tumors, triggers side effects in fewer than 5% of patients. The most severe side effects, however, are septic shock and acute respiratory failure. CASE A 70-year-old man was hospitalized for septic shock with acute respiratory and renal failure after intravesical instillation of BCG, which was identified in the gastric aspiration sample. Treatment with rifampicin, ethambutol, isoniazid, and corticosteroid therapy, as well as standard reanimation measures, led to the patient's recovery. DISCUSSION This case shows the potentially severe side effects of intravesical BCG instillation. Although this treatment is well tolerated in more than 95% of patients and its systemic complications can be effectively treated, these side effects can be life-threatening.

Abstract
A patient with respiratory failure due to undiagnosed tuberculosis in the presence of HIV infection presents to the ICU in a foreign country. This raises many ethical questions, quite apart from the medical management issues raised by the patient's serious condition. Six of these ethical questions have been presented to leading physicians and an ethicist, from a range of national, cultural and religious backgrounds, for their comment.

Abstract
BACKGROUND Clostridium botulinum neurotoxin types A, B, and E cause most cases of the paralytic disease botulism. Little is known about the epidemiology, clinical features, or microbiology of botulism type F. METHODS Cases of adult type F botulism were identified by review of data collected by CDC's National Botulism Surveillance System between 1981 and 2002. A case was either an individual whose serum or stool demonstrated type F toxin or whose stool culture yielded an organism producing toxin type F. A detailed review of cases' medical charts and laboratory data from CDC and local health departments was performed. RESULTS Between 1981 and 2002, 1,269 cases of botulism among adults and infants were reported to CDC; 13 (1%) were adult type F. The median age of type F cases was 54 years; 7 (54%) were female. None were part of outbreaks. A toxigenic Clostridium baratii was identified in 9 (69%) of 13 cases. Among 11 cases for which clinical data were available, all required mechanical ventilation for a median duration of 17 days (range, 10 to 84); 8 (73%) were intubated within 24 hours of symptom onset. All patients had nearly complete or complete quadriplegia at the nadir of neurologic dysfunction, which occurred on average on day 5. On average by day 8, improvement in neuromuscular function was noted. The median duration of acute hospitalization was 31 days (range, 20 to 60). No deaths were reported. In only one case was a possible foodborne etiology identified. CONCLUSIONS Toxigenic C baratii are the sole documented causes of type F botulism in the United States since 1981. These cases are characterized by a fulminant course with rapid progression to respiratory failure and paralysis, making early recognition and intervention critical to appropriate management.

Abstract
A 36-year-old homosexual Mexican man was admitted to our hospital, with a 30-day history of fever and headache. Upon cerebrospinal fluid examination, the patient's white blood cell count was 1,580/L, total protein was 26 mg/dL, sugar was 17 mg/dL, and his intracranial pressure was 23 cmH2O. The patient was diagnosed with HIV (Human Immunodeficiency Virus) infection by serum Western blotting. Cryptococcus neoformans was isolated in cultures of the patient's blood and cerebrospinal fluids. Chest computerized tomography revealed diffuse reticulonodular infiltration and a ground-glass appearance in both perihilar regions, suggestive of either Pneumocystis carinii pneumonia or cryptococcal pneumonia. On the patient's 6th day in our hospital, bronchoalveolar lavage and transbronchial lung biopsy were conducted via bronchoscopy, and a pathologic examination of lung biopsy specimens revealed signs of cryptococcal pneumonia. This patient died on his 14th day in our hospital, as the result of acute respiratory failure, associated with cryptococcal pneumonia and disseminated cryptococcosis.

Abstract
The incidence of B pertussis has increased by 50% from the 1980s to the 1990s, primarily among those aged 4 months and younger. Worldwide, pertussis is a significant cause of infectious mortality with 40 million cases and 400.000 deaths. Most of these cases and deaths occur in infancy. Symptoms vary from common cold in adults to respiratory distress in infants. Non immune babies with respiratory disease and significant lymphocytosis should be considered to have pertussis until proven otherwise. The onset of severe pulmonary hypertension during B pertussis pneumonia is frequenly rapid and relentless. Exchange-transfusion can be life-saving by reducing the leucocyte mass. Classic vaccination or boosters given to adults and adolescents would reduce the spread from parents tho infants, but a new vaccination schedule is under investigation at Vanderbilt Children's Hospital to give baby's first pertussis vaccination at birth?

Abstract
OBJECTIVE To evaluate the feasibility and the efficacy of early extubation and sequential noninvasive mechanical ventilation (MV) switched by pulmonary infection control window (PIC window) in chronic obstructive pulmonary disease (COPD) with exacerbated hypercapnic respiratory failure. METHODS Respiratory or Medical Intensive Care Units (RICU/MICU) of 12 teaching hospitals in China participated in this study. COPD patients with severe hypercapnic respiratory failure exacerbated by pulmonary infection, and for whom intubation and MV were indicated, were enrolled in the study. PIC window was defined as the time point when pulmonary infection was considered under control based on clinical parameters. At PIC window, all the cases were randomly assigned to sequential MV group or conventional MV group. The invasive MV duration, ventilator-associated pneumonia (VAP), days in ICU and mortality rate in both groups were measured. RESULTS Ninety cases were enrolled. Compared with conventional MV group (n = 43) sequential MV group (n = 47) had shorter duration of invasive MV [(6.4 +/- 4.4), (11.3 +/- 6.2) d, P = 0.000], lower rate of VAP (3/47, 12/43, P = 0.014), fewer days in ICU [(12 +/- 8), (16 +/- 11) d, P = 0.047] and lower mortality rate (1/47, 7/43, P = 0.025). CONCLUSION Early extubation followed by non-invasive MV initiated at the point of PIC window may decrease the duration of invasive MV and improve the prognosis.

Abstract
STUDY OBJECTIVES Disseminated strongyloides is a rarely reported phenomenon and occurs in immunosuppressed patients with chronic Strongyloides stercoralis infection. Typically, patients present with pulmonary symptoms but subsequently acquire Gram-negative sepsis. Several cases have been noted in Minnesota, and their presentation, diagnostic evaluation, and clinical outcomes were reviewed. DESIGN A retrospective chart review was conducted of complicated strongyloides infections from 1993 to 2002 in Minneapolis and St. Paul, MN. Cases were identified by reviewing hospital microbiology databases. SETTING Metropolitan hospitals with large immigrant populations. RESULTS Nine patients, all of Southeast Asian heritage, were identified. Eight patients immigrated to the United States > or = 3 years prior to acute presentation. All patients were receiving antecedent corticosteroids; in five patients, therapy was for presumed asthma. Absolute eosinophil counts > 500/microL occurred in only two patients prior to steroid initiation. Eight patients presented with respiratory distress, and Gram-negative sepsis developed in four patients. Four patients had evidence of right-heart strain on ECG or echocardiography at the time of presentation. Three patients died; all had eosinophil counts of < 400/microL. CONCLUSIONS Serious complications, including death, may occur in patients with chronic strongyloides infection treated with corticosteroids. Strongyloides hyperinfection usually presents as acute respiratory failure and may initially mimic an asthma exacerbation or pulmonary embolism. Southeast Asian patients presenting with new-onset "asthma," acute respiratory distress, and/or Gram-negative sepsis should undergo evaluation to exclude strongyloides infection.

Abstract
OBJECTIVE The aim of this study was to assess the incidence and factors associated with pulmonary complications of leptospirosis. METHODOLOGY In a retrospective study, patients with a definite diagnosis of leptospirosis following a 6-week period of severe flooding in Hadyai city, Thailand, were reviewed. Pulmonary complications of leptospirosis were defined as the occurrence of respiratory symptoms and an abnormal CXR. The clinical and laboratory test results for patients with and without pulmonary complications were compared. RESULTS Among the 157 patients with leptospirosis, eight patients had pulmonary complications. Three patients had acute renal failure (ARF) and pulmonary oedema. One patient had ARF and adult respiratory distress syndrome (ARDS). Two patients had ARF, congestive heart failure and pulmonary oedema. One patient had congestive heart failure and pulmonary oedema. One patient had only ARF. Factors associated with pulmonary complications were delayed antibiotic treatment and thrombocytopenia (platelet count < 100 x 10(9)/L). Three patients developed adult respiratory distress syndrome and one died from respiratory failure. CONCLUSIONS Pulmonary complications and death occur in a low percentage of patients with leptospirosis. Delayed antibiotic treatment and thrombocytopenia are risk factors for the development of pulmonary involvement in leptospirosis.

Abstract
Diffuse pulmonary hemorrhage leading to death is a syndrome which may develop in leptospirosis, but its pathophysiology is not well documented. We report an autopsy case of leptospirosis. A healthy 41-year-old man presented with low back myalgia, dry cough and fever for 4 days and a normal chest X-ray on admission. Acute respiratory failure developed hours later. Profuse bloody fluid appeared in the endotracheal tube immediately after intubation. Chest X-ray showed whiteness across all lung fields. He died of persistent shock 16 h after the onset of acute respiratory failure. Autopsy revealed diffuse pulmonary hemorrhage with hyaline-membrane formation, myocarditis, interstitial nephritis and hepatitis. Silver stain of lung and kidney tissue demonstrated leptospires. Immunohistochemical staining showed inducible nitric oxide synthase in alveolar macrophages. Immunofluorescein staining showed immunoglobulin in alveolar septum and alveolar space. This case suggests that hemorrhagic diffuse alveolar damage with persistent shock is related to over-production of nitric oxide and immunoglobulin deposition in fatal leptospirosis.

Abstract
Tissue factor expression in sepsis activates coagulation in the lung, which potentiates inflammation and leads to fibrin deposition. We hypothesized that blockade of factor X binding to the tissue factor-factor VIIa complex would prevent sepsis-induced damage to the lungs and other organs. Acute lung injury was produced in 15 adult baboons primed with killed Escherichia coli [1 x 10(9) colony-forming units (CFU)/kg], and then 12 h later, they were given 1 x 10(10) CFU/kg live E. coli by infusion. Two hours after live E. coli, animals received antibiotics with or without monoclonal antibody to tissue factor intravenously to block tissue factor-factor X binding. The animals were monitored physiologically for 34 h before being killed and their tissue harvested. The antibody treatment attenuated abnormalities in gas exchange and lung compliance, preserved renal function, and prevented tissue neutrophil influx and bowel edema relative to antibiotics alone (all P < 0.05). It also attenuated fibrinogen depletion (P < 0.01) and decreased proinflammatory cytokines, e.g., IL-6 and -8 (P < 0.01), in systemic and alveolar compartments. Similar protective effects of the antibody on IL-6 and -8 expression and permeability were found in lipopolysaccharide-stimulated endothelial cells. Blockade of factor X binding to the tissue factor-factor VIIa complex attenuates lung and organ injuries in established E. coli sepsis by attenuating the neutrophilic response and inflammatory pathways.

Abstract
Allergic bronchopulmonary aspergillosis (ABPA) is an uncommon condition which may complicate asthma and cystic fibrosis; it is seldom considered life-threatening. We report a well 8-year-old boy with cystic fibrosis and normal lung function who progressed to respiratory failure over several days, attributable to ABPA. He recovered with non-invasive ventilation and oral corticosteroid and antifungal medications, regaining normal lung function within 2 months. To our knowledge, such an acute severe presentation of ABPA in a previously well child has not been reported before.

Abstract
Pulmonary mycoses count among the most dangerous complications in allogeneic hematopoietic stem cell transplantation. Despite the establishment of antifungal chemoprophylaxis and empirical antifungal treatment, they frequently lead to respiratory failure and are still associated with an extraordinarily poor prognosis. However, the emergence of new antimycotics with alternative mechanisms of actions and decreased toxicity in combination with the development of new non culture-based diagnostic techniques may allow earlier, more aggressive and more effective antifungal treatment approaches. In addition, the optimized use of new technologies designed to augment spontaneous breathing efforts by patients, mechanical ventilation, as well as the advantages of early tracheostomy lead us to expect better outcomes in the treatment of respiratory failure due to pulmonary mycoses following allogeneic hematopoietic stem cell transplantation.

Abstract
Community-acquired pneumonia (CAP) is the sixth most common cause of death in the United States and the leading cause of death from infectious diseases. It is associated with significant morbidity and mortality, and poses a major economic burden to the healthcare system. Streptococcus pneumoniae is the leading cause of CAP. Other common bacterial causes include Haemophilus influenzae as well as atypical bacteria (Mycoplasma pneumoniae, Chlamydia pneumoniae, and Legionella species). Increasing resistance to a variety of antimicrobial agents has been documented in S. pneumoniae and is common in H. influenzae as well. Successful empiric therapy is paramount to the management of CAP to avoid treatment failure and subsequent associated costs. Given that resistance is increasing among respiratory pathogens, and S. pneumoniae is the most common etiologic agent identified in CAP, strategies for antimicrobial therapy should be based on the likely causative pathogen, the presence of risk factors for infection with resistant bacteria, and local resistance patterns.

Abstract
Spinal epidural abscess (SEA) is a neurological emergency that requires urgent diagnosis and treatment. We report 2 patients with SEA, in whom, on neuropathological examination, the neurological signs were found to be caused by spinal cord ischemia due to thrombosis of leptomeningeal vessels and compression of spinal arteries, respectively, while evidence of spinal cord compression was absent. Clinicians and neuropathologists should be aware of the variable mechanisms underlying the neurological involvement in SEA. Absence of spinal cord compression by the abscess may hamper early diagnosis and treatment.

Abstract
A 5-year-old Paso-Fino mare was presented for severe respiratory distress. The mare had foaled 2 months prior to presentation. The horse was in poor body condition with a dull hair coat. A mild fever was noted during physical examination and increased bronchovesicular sounds were auscultated. Thoracic radiographs showed an interstitial pattern and an alveolar infiltrate with distinct air bronchograms. Moderate purulent inflammation with increased mucus was observed in tracheal wash fluid, but no infectious agents were identified. A bronchoalveolar lavage (BAL) contained a large amount of mucus and reactive mononuclear phagocytes with variable numbers of intracellular fungal organisms morphologically consistent with Pneumocystis carinii. The mare had undetectable levels of immunoglobulin M (IgM) and decreased IgG levels in the serum. Immunophenotyping revealed decreased expression of major histocompatibility complex (MHC) class II molecules. Moderate to marked hyperplasia of type II epithelial cells was present throughout histologic sections of lung, but the fungal organisms were not observed. A culture system has not been developed for diagnosis of P carinii infection. Instead, diagnosis of P carinii pneumonia is achieved by microscopic identification of characteristic morphologic features of the pathogen. Cytologic examination of BAL fluid is the preferred method used to diagnose human infection with P carinii. In humans, the diagnostic sensitivity of cytology is significantly higher than the sensitivity of histopathologic examination of lung biopsies. The difference in sensitivity between BAL cytology and lung histopathology may also apply to the diagnosis of P carinii pneumonia in horses.

Abstract
Mortality remains high among patients with pulmonary tuberculosis requiring mechanical ventilation (TBMV). This study was carried out to establish the mortality rates of TBMV and to identify factors that contribute to in-hospital mortality. From January 1996-April 2001, there were 825 patients with active pulmonary tuberculosis at the National Taiwan University Hospital, Taipei, Taiwan. Of these, 41 suffered acute respiratory failure and required mechanical ventilation in the intensive care unit (ICU). Of these 41 patients, 38 were followed up for 180 days. In-hospital deaths were documented in the medical records and all possible parameters contributing to mortality were collected. Of the 41 patients, 27 died in the hospital and 14 were discharged alive (in-hospital mortality rate 65.9%), with (mean +/- SD) 40.7 +/- 35.4 admission days before death. Of the 27 that died, 25 died during ICU admission and two died after being transferred to the ward. The mortality rate for the 180-day monitoring period was 79%. Factors contributing to in-hospital mortality included consolidations on chest radiographs and multiple organ failure. The mortality rate in the patients with pulmonary tuberculosis requiring mechanical ventilation is very high, with two factors affecting in-hospital mortality. These factors were multiple organ failure and consolidation on chest radiographs.
