Abstract
Serious non-fatal complications of cardiac surgery include deep sternal wound infection (DSWI) and haemorrhage. Understanding the factors associated with these complications (both pre-operatively and intra-operatively) may aid in the prevention and avoidance of such complications. The aim of the current report is to identify factors associated with DSWI and haemorrhage for all patients undergoing cardiac surgical procedures in Victorian public hospitals from July 2001 to June 2005. Multiple logistic regression analysis incorporating preoperative and intraoperative variables was used to identify risk factors for DSWI and haemorrhage. There were 153 cases of DSWI (1.3%) and 413 cases of haemorrhage (3.5%) in 11,848 patients. The risk factors differ between DSWI and haemorrhage, with pre-operative factors being more commonly associated with DSWI and intra-operative factors associated with haemorrhage. Strategies directed towards minimising modifiable pre-operative risk factors (diabetes, preoperative dialysis, respiratory disease, being overweight and angina CCS Class 3 or 4) may reduce the incidence of DSWI. Improvements in operative factors (perfusion time, ventricular assist device, intraaortic balloon pump and aortic dissection) and surgical technique, may impact on reducing the incidence of haemorrhage.

Abstract
Progressive respiratory failure is a common modality of death in children with a terminal illness. The management of respiratory failure, and in particular symptoms of dyspnoea and musculoskeletal chest pain in children receiving palliative care, remains challenging. The emergence of palliative care paediatricians and the application of non-invasive ventilation to children with progressive respiratory failure are the two major advances in the care of children with respiratory complaints in the palliative care setting. This article outlines current approaches to palliative care in children with progressive respiratory symptoms.

Abstract
As yet, in vitro assessment of the immunotoxic potency of respiratory agents is not possible. The complexity of the endpoint and the respiratory tract, and the limited availability of well-documented respiratory agents are the main reasons. The evidence that epithelial cells (ECs) are triggered by compounds to express in vitro surface proteins and soluble mediators, has stimulated their use for developing tests for respiratory immunotoxicity. A variety of airway ECs and EC-lines have been assessed, but the available information seems to point at human alveolar cells (e.g., A549) as the most convenient cell type. EC-based test formats with various degrees of complexity have been assessed. Sofar, promising results were obtained using a 3D model using the human A549 lung cell line. Dendritic cells (DCs) have been subjected to intensive research. However, currently available tests are not well suited to discern among the potency of sensitizers. Potential explanations include the lack of standardised protocols for the generation of DCs, no good standards for estimating the quality of in vitro derived DC-cultures, and limited dynamics of the currently used end-points. Alveolar macrophages (AMs) have so far received less attention. This may proof unjustified as macrophages may link innate responses to adaptive immunity. The observation that ECs, DCs and AMs affect each other, suggests that test formats are required combining at least two of these cell types if ranking of compounds according to their sensitising potency is the aim. In addition, the capacity of compounds to cross a cellular membrane is an important property of an immunotoxic compound, which can be assessed only in 3D reconstituted human tissue models. While promising data have been reported for the skin, immunocompetent 3D reconstituted human lung remains to be evaluated for respiratory immunotoxicity. Obviously, the success of any of these simplified test (as compared to the complexity of the immune response) is highly dependent on the availability of early stage biomarkers (expressed at mucosal barrier level) that are predictive for relevant immunotoxicity mechanisms occurring down-stream of the immune response. As yet, such biomarkers are not yet available.

Abstract
The patient of chronic respiratory disease belongs to high risk group of the influenza, and when influenza will happen, they will become sever. Therefore, these patient should take the vaccination at first. Being vaccinated, even if the influenza will occur, the condition will not be sever and with the antiviral agents, anti-bacterial agents should be given with or without the existence of bacterial infection.

Abstract
La toux est très fréquente au cours de l’asthme. Elle est constante eu cours de la bronchite chronique qu’elle contribue à définir ; habituellement cette bronchite chronique est d’origine tabagique mais l’inhalation de canabis, des expositions professionnelles, la pollution domestique ou atmosphérique, peuvent également être en cause. Au cours de l’asthme et de la bronchite chronique, la toux résulte de l’inflammation et de l’hypersécrétion de la muqueuse bronchique. Chez le fumeur, la toux peut également révéler un cancer bronchique. Parmi les nombreuses autres causes de toux chronique, la dilatation des bronches est habituellement reconnue contrairement à la bronchite à éosinophiles.

Abstract
The authors describe the case of a near-fatal airway obstruction requiring extracorporeal membrane oxygenation. The patient presented with severe respiratory distress owing to a bean impacted in the distal trachea. The foreign body could not be removed by bronchoscopy because of instability of the patient. The patient was placed on extracorporeal membrane oxygenation for temporary pulmonary support, and the foreign body was removed using a rigid bronchoscope. The patient had a full recovery and suffered no neurologic sequelae.

Abstract
We assessed the health of workers exposed to the World Trade Center (WTC) site and of a comparison group of unexposed workers, by means of a mail survey. Exposed workers reported higher frequency of symptoms consistent with posttraumatic stress disorder (PTSD), depression, anxiety, and other psychological problems, approximately 20 months after the disaster. PTSD was positively associated with traumatic on-site experiences and with respiratory problems. These findings may have important clinical and public health implications.

Abstract
BACKGROUND Chronic hepatitis C virus infection has been reported in association with several extrahepatic manifestations. Included in this list is interstitial lung involvement. AIMS The aim of the present study was to evaluate pulmonary alterations in patients with chronic hepatitis C virus infection. PATIENTS Twenty-one patients with chronic hepatitis C virus infection were enrolled into a prospective study. One patient has been excluded because of underlying tuberculosis. METHODS All patients underwent pulmonary function tests, diffusion capacity for carbon monoxide and high-resolution computed tomography of the chest. RESULTS Forced vital capacity, forced expiratory volume in first second/forced vital capacity and forced expiratory volume in first second values were reduced to less than 80% of predicted values in 3, 11 and 5 patients, respectively. Diffusion capacity for carbon monoxide was low in 12 patients (60%), 8 of whom had simultaneous decrease in diffusion capacity for carbon monoxide/VA values. Thorax high-resolution computed tomography revealed abnormal findings in eight patients (40%). Fifteen patients with chronic hepatitis C virus infection (75%) had at least one pulmonary alteration as evidenced by abnormal pulmonary function tests, diffusion capacity for carbon monoxide and/or high-resolution computed tomography results. CONCLUSION In spite of a limited study population, these findings may implicate that pulmonary manifestations of chronic hepatitis C virus infection are frequently underdiagnosed.

Abstract
Recent studies suggest an epidemiological association between Helicobacter pylori infection and several extra-gastroduodenal pathologies, including cardiovascular, rheumatic, skin and liver diseases. The observed associations might be explained by a role of H. pylori infection in the pathogenesis of certain extra-digestive disorders, as a variety of inflammatory mediators are activated by H. pylori infection. The present review summarizes the current literature, including our own studies, concerning the association between respiratory diseases and H. pylori infection. A small number of epidemiological and serologic case-control studies suggest that patients with chronic obstructive pulmonary disease have an increased seroprevalence of H. pylori. A frequent coexistence of bronchiectasis and H. pylori infection has also been found. Moreover, recent studies have shown an increased prevalence of H. pylori infection in patients with pulmonary tuberculosis and in those with lung cancer. On the other hand, bronchial asthma does not seem to be related to H. pylori infection. At present, there is no definite proof of a causal relationship between H. pylori and respiratory diseases. The primary evidence rests on case-control studies, concerning relatively small numbers of patients. Future studies should be large enough for moderate-sized effects to be assessed or registered reliably. The activation of inflammatory mediators by H. pylori infection might be the pathogenetic mechanism underlying the observed associations. Therefore, the role of genetic predisposition of the infected host, the presence of strain-specific virulence factors and the serum concentration of proinflammatory markers in H. pylori-infected patients with respiratory diseases need further evaluation.

Abstract
The objective of the study was to investigate factors related to the occurrence of myelodysplatic syndromes (MDS) in the population of Belgrade (Serbia Montenegro). The case-control study was conducted during the period 2000-2003. The study group consisted of 80 newly diagnosed MDS patients and 160 sex- and age-matched hospital controls with nonmalignant and noninfectious diseases. The disease categories in the control group were circulatory (51 patients, 32%), gastrointestinal (53 patients, 33%), and ophthalmological (56 patients, 35%) disorders. Conditional univariate and multivariate logistic regression analyses were applied. Multivariate analysis showed the following factors to be significantly related to MDS: exposure to chemicals (OR = 10.8, 95%CI 3.2-36.2, p = 0.0001), viral upper respiratory tract infections (twice a year or more, OR = 5.8, 95%CI 2.5-13.6, p = 0.0001), exposure to insecticides, pesticides and herbicides (OR = 5.2, 95%CI 1.8-15.1, p = 0.003), coffee (OR = 5.1, 95%CI 1.9-13.7, p = 0.001), and alcohol consumption (OR = 2.2, 95%CI 1.1-4.6, p = 0.033). The findings support the hypotheses that exposure to chemical agents, pesticides, insecticides, and herbicides, certain lifestyle factors (alcohol and coffee consumption), and frequent viral infections may be involved in the etiology of MDS, but these results should be confirmed by further investigations.

Abstract
Sedentary lifestyles and increased pollution brought about by industrialization pose major challenges to the prevention of both obesity and chronic respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma, obstructive sleep apnea and obesity hypoventilation syndrome. Obesity has emerged as an important risk factor for these respiratory diseases, and in many instances weight loss is associated with important symptomatic improvement. Moreover, obesity may influence the development and presentation of these diseases. In this article, we review the current understanding of the influence of obesity on chronic respiratory diseases and the clinical management of obesity concurrent with asthma, COPD, obstructive sleep apnea or obesity hypoventilation syndrome.

Abstract
Recent research has greatly improved our understanding of the pathophysiology of pulmonary hypertension. There is increasing recognition that pulmonary hypertension is an important complication of many childhood respiratory diseases including cystic fibrosis, interstitial lung diseases, upper airways obstruction and disorders of the respiratory muscles and chest wall. Chronic hypoxaemia and, in some cases, destruction of the vascular bed are the key factors. The clinical features of pulmonary hypertension are often overshadowed by those of the primary respiratory disease but newer imaging techniques allow earlier detection of this complication. This may be important in the future if new specific therapies for primary pulmonary hypertension are shown to be beneficial in secondary pulmonary hypertension. With some conditions, such as airways obstruction due to adenotonsillar hypertrophy, treating the underlying cause leads to rapid resolution of the hypertension. However, with most disorders, such as cystic fibrosis, management is focused on treating the lung disease intensively and correcting the chronic hypoxaemia with oxygen therapy, sometimes augmented by nasal mask ventilation. However, although several new selective therapies are effective in idiopathic pulmonary arterial hypertension, their role in secondary pulmonary hypertension remains unclear.

Abstract
Cough is a common presenting symptom to paediatricians and paediatric respiratory physicians. The causes of chronic cough in childhood are significantly different from those in adults, and a different approach to diagnosis and management is needed. In most cases cause can be identified or a satisfactory label given. This review will cover the approach to cough in children and cover some specific causes of troublesome cough not discussed elsewhere in this mini-symposium.

Abstract
Suppurative cough can be defined as a cough where purulent sputum is produced. Chronic suppurative cough may be associated with the destruction of the bronchial wall (bronchiectasis). As mild forms of the disease are not associated with respiratory limitation or failure to thrive, such children may not present for investigation and therefore the true incidence of suppurative cough is difficult to gauge. Chronic suppurative cough remains an important health problem in developing countries and some indigenous populations of developed countries. The purpose of this review is to present the appropriate investigations and evaluate the evidence for current management strategies in children with suppurative cough. To accomplish this, a brief discussion on the aetiology of suppurative cough in childhood is presented. The most commonly identifiable cause of suppurative cough is cystic fibrosis. A detailed discussion on cystic fibrosis is beyond the scope of this review. Other causes of chronic suppurative cough in pre-school children may be classified according to congenital malformations of the airway, immunodeficiency, ciliary dysfunction and, unusually, acquired causes. Microbiology of sputum culture or bronchoalveolar lavage, assessment of immune function, the role of exhaled nitric oxide and ciliary studies, and medical imaging are discussed in detail. One can conclude that the evidence for management strategies for children with suppurative cough is, at best, level 3 evidence, i.e. non-randomised, controlled or cohort studies.

Abstract
Patients with cancers caused by smoking may die because they continue to smoke even after diagnosis of a cancer caused by smoking. We investigated differences in cause-specific mortality between patients diagnosed with smoking-related and non-smoking-related cancers. The causes of death were classified as smoking-related cancer, non-smoking-related cancer, respiratory or vascular disease, and all other causes. We studied all 220 089 people diagnosed with cancer in Scotland between 1986 and 1996, aged between 20 and 85 years, with last follow-up on 31 December 1999. There was a moderate excess risk of dying from respiratory and vascular causes in those with smoking-related cancers, which did not fall with time since diagnosis, consistent with continued smoking by these patients. Mortality among cancer patients might fall if more assistance in stopping smoking was provided for patients who have smoking-related cancers.

Abstract
STUDY OBJECTIVES To assess whether prior outpatient treatment is associated with outcome in patients hospitalized for community-acquired pneumonia (CAP). PATIENTS AND METHODS All patients with a first hospital admission for CAP between 1995 and 2000 were selected. Patients were divided into two groups, one of patients with use of antibacterial agents prior to hospitalization and one of patients treated as inpatient directly. The main outcome measures were duration of hospital stay and in-hospital mortality. RESULTS The two patient groups comprised 296 and 794 patients, respectively. The median duration of hospital stay was 10 days and was similar for both groups. In patients with respiratory diseases or heart failure, the median duration of hospital stay was 12 and 14 days, respectively. The overall in-hospital mortality was 7.2% and did not largely differ between both groups. In patients with congestive heart failure, the mortality was 9.8% for controls and 23.3% for patients hospitalized after initial outpatient treatment (adjusted OR 2.78, 95% CI 1.01-7.81). CONCLUSIONS Prior outpatient antibacterial therapy is not associated with outcome in hospitalized pneumonia patients. In patients with underlying chronic heart failure, prior outpatient antibiotic is associated with a significant increased mortality.

Abstract
Chest physicians frequently come across with the symptom hemoptysis, an alerting symptom which may result from a wide variety of disorders. In this study, we aimed to determine the main causes of hemoptysis in a reference hospital for chest diseases. All the patients who admitted to our emergency clinic with hemoptysis during three months of study period were included in the study. The mean age of 143 patients (106 males, 37 females) who were included in this study was 48 +/- 17 years. Medical history, physical examination and chest radiography were performed for each patient. Sputum examination for acid fast bacilli, computed tomography of thorax, fiberoptic bronchoscopy, ventilation-perfusion scintigraphy, echocardiography, ear-nose-throat examination and upper gastrointestinal system endoscopy were the further diagnostic investigations for selected patients. Bronchiectasis was the most common cause of hemoptysis (22.4%), followed by lung cancer (18.9%), active tuberculosis (11.2%), and inactive tuberculosis (10.5%). Sputum smear for acid fast bacilli was performed in 102 patients and were positive in 15.6% of them. Computed tomography of thorax was performed in 102 patients and was pathologic in 81.3% of them. Fiberoptic bronchoscopy was performed in 46 patients and localized the bleeding site in 67.4% of them. In conclusion, the most common causes of hemoptysis were bronchiectasis, lung cancer and tuberculosis in our hospital. Based on this finding, we suggest that, the diagnostic approach to the patients presenting with hemoptysis should include first a detailed medical history, physical examination, and chest radiography; second sputum smear for acid fast bacilli; third computed tomography of thorax and lastly fiberoptic bronchoscopy.

Abstract
Everyday clinical practice reveals both cases of asthma with non-typical symptoms as well as pseudo-asthmatic syndromes with symptoms typical for asthma. Bronchofiberoscopy is a diagnostic method which may help to overcome many diagnostic problems. Although it is a safe procedure, an increased risk of severe bronchoconstriction exists in patients with asthma. The fear of this complication may cause late diagnosis of some asthma-mimicking diseases and may delay the proper treatment. In the present paper we describe two cases showing the possibility of making diagnostic mistakes, and especially illustrating the role ofbronchoscopy in differential diagnosis of bronchial asthma. The authors remind specific indications for this examination in patients with asthma or those presenting asthma-like symptoms. Safety precautions have been also recollected. If safety rules are met, severe bronchoconstriction in patients with bronchial hyperreactivity can be avoided.

Abstract
BACKGROUND AND PURPOSE The re-admission of patients to intensive care is associated with increased morbidity, mortality, loss of morale for patients and family, and increased health costs. The aim of the present study was to identify factors which place patients at a higher risk of re-admission to intensive care. METHOD A prospective study of patients who were re-admitted to a 22-bed tertiary level intensive care facility within a 12 month period. Data were kept on every patient re-admitted to intensive care, including standard demographic data, initial admission diagnosis, co-morbidities, re-admission diagnosis, mobility on discharge, secretions, airway, chest X-ray, PaCO2, PaO2, PaO2/FiO2 and time of discharge. Subjects included 74 patients who had been re-admitted to intensive care in 12-month period and a comparison group of patients who were not re-admitted to intensive care. A cross-tabs procedure was initially used to estimate maximum likelihood. Significant factors with an alpha value of <0.10 were entered into a backward conditional binary logistic regression to determine independent factors. RESULTS The overall percentage of patients who were re-admitted to intensive care compared with total admissions was 7.7%. Significant independent factors for re-admission were found to be age >65 years (p<0.05), colonization (p<0.001), weakness (p<0.001), co-morbidities of cardiac and/or respiratory disease (p<0.001) and depression (p<0.001). CONCLUSIONS A certain profile of patients has been established who are at increased risk of re-admission to intensive care. These patients could be provided with increased intervention and surveillance on discharge from intensive care.

Abstract
OBJECTIVE To investigate causes of death in individuals with traumatic brain injury (TBI). DESIGN Retrospective cohort study. SETTING Utilized data from the TBI Model Systems National Database, the Social Security Death Index, death certificates, and the US population age-race-gender-cause-specific mortality rates for 1994. PATIENTS Two thousand one hundred forty individuals with TBI completing inpatient rehabilitation in 1 of 15 National Institute on Disability and Rehabilitation Research-funded TBI Model Systems of Care between 1988 and 2001, and surviving past 1 year postinjury. MAIN OUTCOME MEASURES Primary cause of death based on the International Classification of Diseases--9th Revision--Clinical Modification-coded death certificates. RESULTS Individuals with TBI were about 37 times more likely to die of seizures, 12 times more likely to die of septicemia, 4 times more likely to die of pneumonia, and about 3 times more likely to die of other respiratory conditions (excluding pneumonia), digestive conditions, and all external causes of injury/poisoning than were individuals in the general population of similar age, gender, and race. CONCLUSION Long-term follow-up of individuals with TBI should increase vigilance for, and prevention of, diagnoses frequently causing death (circulatory disorders) and diagnoses with a high relative risk of causing death in this population (seizures, septicemia, respiratory and digestive conditions, and external causes of injury).

Abstract
Pulmonary hypertension associated with disorders of the respiratory system is defined by a pulmonary artery mean pressure above 20 mmHg at rest in stable disease. The most frequent form of precapillary pulmonary hypertension is associated with chronic obstructive pulmonary disease, because of its high prevalence. Pulmonary vascular remodeling occurs in the small pulmonary arteries and is due mainly to chronic alveolar hypoxia. Pulmonary hypertension associated with disorders of the respiratory system is usually mild to moderate, with resting pulmonary artery mean pressure ranging between 20 and 35 mm Hg. It may increase markedly during sleep, exercise or exacerbation of respiratory failure, however. Abrupt postload elevation can lead to right heart failure, an indisputable indicator of prognosis. Because the symptoms of pulmonary hypertension are minimal relative to those of the chronic hypoxic lung disease, noninvasive diagnosis is difficult, particularly in patients with chronic obstructive pulmonary disease. Oxygen therapy (at least 16 h/day) is currently the best treatment for this type of pulmonary arterial hypertension.

Abstract
Objective To document the prevalence of respiratory virus infections in patients with chronic cardiac or pulmonary disorders admitted to a critical care unit for acute cardiorespiratory failure. Design, setting, patients The study took place in a critical care unit during two consecutive winters. All patients admitted to the unit for acute respiratory or cardiac failure were enrolled. A nasal swab was taken for polymerase chain reaction (PCR) detection of influenza virus, respiratory syncytial virus (RSV), metapneumovirus, rhinovirus, and coronavirus. Results One hundred twenty-two patients were enrolled. Their mean age was 69 years; 42% of the patients were female; the new simplified acute physiology score (SAPS II) score on admission was 35.6; 94% of patients had acute respiratory failure, 14% reported “influenza-like” illness before admission, and 11% of patients died in the unit. Twenty-one patients (17%) tested positive for a respiratory virus. The per-1,000 positivity rates were influenza virus 66, RSV 49, rhinovirus 33, metapneumovirus 16, and coronavirus 8. No link was found between virologic results and clinical outcome. A strong link was found between the rate of influenza virus positivity and the incidence of flu-like illness in the community (p=0.017). Conclusion These results show that respiratory virus infection—particularly influenza virus infection during epidemic periods—is common among patients hospitalized for acute cardiorespiratory failure.

Abstract
OBJECTIVES To determine individual differences in the impact of illness on the change in performance of swimmers in international competitions. METHODS Subjects were members of the Australian swimming team (33 male and 39 female, aged 15-27 years). Swimmers provided a weekly seven day recall of symptoms of illness during final six weeks of preparations for international competition over a three year period. Swimmers were categorised as either ill (one or more episodes of illness) or healthy. The measure of performances was the international point score. Mean changes in points score were calculated for healthy and ill swimmers between a national championship and an international competition ( approximately 16 weeks later). Likelihoods of substantial effects of illness on an individual's true change in performance (beneficial/trivial/harmful) were estimated from means and standard deviations, assuming a smallest substantial change of 6 points. RESULTS Illness was reported before international performances by 38% of female and 35% of male swimmers. For female swimmers the change in performance was -3.7 (21.5) points (mean (SD)) with illness and -2.6 (19.0) points when healthy; for male swimmers the changes were -1.4 (17.5) points with illness and 5.6 (13.2) points when healthy. The likelihoods that illness had a substantial beneficial/trivial/harmful effect on performance of an individual swimmer were 32%/31%/37% for female and 17%/31%/52% for male participants (90% confidence limits approximately +/-10% to 20%). CONCLUSIONS Although mild illness had only a trivial mean effect on female swimmers and a small harmful mean effect on male swimmers, there were substantial chances of benefit and harm for individuals.

Abstract
In this note we extend the logistic regression receiver operating characteristic (ROC) analysis framework to diagnosing disease that can be classified in a 2 x 2 factorial setting. Similar to the standard ROC curve analysis these new models accommodate prediction of cross-classifications for treatment success and diagnosis of disease. A didactic example is given for jointly diagnosing malaria positive and respiratory distress in children in Ghana.

Abstract
BACKGROUND Accurate characterisation of subjects is essential to interpret data from studies investigating preschool wheezing. AIM To assess whether a video questionnaire (VQ) identifies upper airway abnormalities in preschool children with reported wheeze. METHODS Forty three children (median age 17 months, range 3-58) undergoing fibreoptic bronchoscopy for clinical investigation of troublesome noisy breathing at a tertiary centre were studied. Parents were shown a VQ with four clips (wheeze, stridor, and two other upper respiratory noises) and chose the clip(s) resembling their child's main symptom. Doctor observed symptoms, parental reported symptoms, and symptoms identified on VQ were related to bronchoscopy. RESULTS Thirty subjects had wheeze as the main symptom: 19 had doctor observed wheeze (DOW) and 11 had parental reported wheeze (RW). Parents of two of the subjects with RW identified wheeze alone on VQ and both had normal bronchoscopic findings. Five of the remaining nine subjects with RW had upper airway abnormalities at bronchoscopy. Parents of six subjects with RW identified a noise other than wheeze on VQ; four of these had upper airway abnormalities. Parents of two subjects with RW did not identify a noise on VQ; one had upper airway abnormalities. Of the 19 with DOW, nine parents identified wheeze alone on VQ, and all had a normal upper airway. Parents of nine subjects with DOW identified a noise other than wheeze as an equal or only symptom, (no noise identified in one), and five had upper airway abnormalities. CONCLUSION A VQ helps to identify upper airway abnormalities in preschool children with a history of wheezing.

Abstract
The possibility that a subject's psychological status may influence respiratory sensations and that chronic respiratory disease may have psychological consequences has sparked great interest among clinicians and researchers. This paper reviews the existing research on the association between respiratory symptom perception and the psychological status and between chronic respiratory diseases, such as asthma and chronic obstructive pulmonary disease, and psychological disturbances. Moreover, it focuses on the role of stressful events in determining asthma exacerbations. The recent literature suggests that in patients with chronic respiratory diseases, the evaluation of breathlessness perception, psychological disturbances and the recording of any stressful events should be considered as relevant as the physical and functional assessment of respiration.

Abstract
Inflammatory lung diseases are characterised by increased expression of multiple inflammatory genes that are regulated by proinflammatory transcription factors, such as nuclear factor-kappa B. Gene expression is regulated by acetylation of core histones through the action of coactivators, such as CREB-binding protein, with intrinsic histone acetyltransferase (HAT) activity. Conversely, gene repression is mediated via histone deacetylases (HDACs) and other corepressors. In asthma, there is an increase in HAT activity and some reduction in HDAC activity, which is restored by corticosteroid therapy. Corticosteroids switch off inflammatory genes in asthma through the inhibition of HAT activity and by the recruitment of HDAC2 to the activated inflammatory gene complex. In chronic obstructive pulmonary disease, there is a reduction in HDAC2 activity and expression, which may account for the amplified inflammation and resistance to the actions of corticosteroids. The reduction in HDAC2 may be secondary to oxidative and nitrative stress as a result of cigarette smoking and severe inflammation, and may also occur in severe asthma, smoking asthmatic patients and cystic fibrosis. Similar mechanisms may also account for the steroid resistance seen with latent adenovirus infections. The reduction in histone deacetylase activity can be restored by theophylline, which may be able to reverse steroid resistance in chronic obstructive pulmonary disease and other inflammatory diseases.

Abstract
Esophageal cancer has a fulminant biological characteristic, and shows a higher rate of lymph node metastasis than other gastrointestinal malignancies. The distribution of lymphatic spread is wide from cervical to abdominal field, and 3-field lymph node dissection is a standard procedure in esophageal cancer surgery. However, the morbidity and mortality rate following esophageal resection is higher than that of other gastrointestinal or thoracic surgery. The most serious postoperative complication of esophageal surgery in elderly patients is a pulmonary problem. In order to reduce postoperative pulmonary complications, we try to preserve bronchial artery, pulmonary branches of the vagal nerve, in addition to definite preservation of bilateral recurrent laryngeal nerve. Our survival rate and mean survival period in elderly patients with esophageal cancer was fairly good. To achieve a high survival rate and reduce postoperative morbidity and mortality in elderly patients, preoperative assessment of pulmonary function and quality control of surgical procedure is essential.

Abstract
An understanding of the appearance of the infant chest radiograph requires an understanding of the anatomy and the physiologic, immunologic, and pathologic processes in the infant's chest. The authors describe the features of the infant chest that most influence the appearance of the chest radiograph in infants with cough and fever. They discuss why confusion sometimes occurs when radiology residents and general radiologists familiar with adult chest radiographs first evaluate the infant chest radiograph. The radiographic appearance of acute inflammation does not look the same in infants as it does in older children and adults. The hallmark of inflammatory lung disease in the infant chest is air trapping on the chest radiograph.

Abstract
BACKGROUND AND PURPOSE In the present study we attempt to determine the prevalence of International Classification of Disease-ninth revision, Clinical Modification (ICD-9 CM) coded sleep apnea with cardiovascular and metabolic co-morbidities in Veterans Health Administration (VHA) beneficiaries. PATIENTS AND METHODS Using VHA administrative databases, we gathered available medical information on more than 4 million veterans using the VHA during the period between 1998 and 2001. We identified database entries for codes indicating sleep apnea using the ninth revision of the Clinical Modification of the International Classification of Diseases (ICD-9 CM); and tabulated demographic data including age, gender, ethnicity, and cardiovascular and metabolic co-morbidities. RESULTS We found 118,105 unique cases (out of 4,060,504) with sleep apnea ICD-9 CM codes (prevalence of 2.91%). Mean age at diagnosis was 57.6 with more than 38% older than 65 years. Comorbid diagnoses in this group included hypertension (60.1%), obesity (30.5%), diabetes mellitus (32.9%), cardiovascular disease (including MI and angina) (27.6%), heart failure (13.5%), and cerebrovascular accident (including Transient Ischemic Attack (TIA)) (5.7%). CONCLUSIONS We found a high prevalence of diagnosed sleep apnea among VHA beneficiaries. Additionally, cardiovascular and metabolic conditions were common in these patients.

Abstract
The features of delirium in patients being hospitalized due to respiratory diseases were investigated. From the inpatients in the respiratory medical ward of Tokyo Metropolitan Hiroo General Hospital over the course of 1 year, the patients who had delirium were diagnosed by a semistructured interview. The total number of subjects was 454, and patients with delirium were 43. Various clinical factors were compared between the delirium group and non-delirium group. In the delirium group, there were many elderly patients of 70 years or older. Moreover, there were many patients who had a chronic respiratory disease, patients in which the respiratory diseases were mutually complicated, and patients in whom other diseases combined with the respiratory disease in the delirium group. There were also many patients in the Intensive Care Unit (ICU), and patients with an endotracheal intubation or extubation. Based on the results of a multiple logistic regression analysis, for age, ICU accommodation, and endotracheal intubation, the value of the delirium group was more significant than that of the non-delirium group. In half of the patients from the delirium group, delirium developed within 1 week after hospitalization. In the patients who died in the hospital, however, delirium often developed days after they had been hospitalized. It was suggested that the later developed delirium had a relation to the prognosis.

Abstract
A few cases of death worldwide during GH treatment in pediatric patients with Prader-Willi syndrome (PWS) have been recently described. The evaluation of further cases is needed to better identify possible causal mechanism(s), as well as to suggest some additional guidelines for prevention. We report the death of 2 additional children with genetically confirmed PWS in the first months of GH therapy. Case 1: This 3.9-yr-old girl was born at 39 weeks gestation. Low GH response to two stimulation tests was observed. GH administration was started at the age of 3.5 yr (0.33 mg/kg per week), when the patient was at 130% of her ideal body weight (ibw). Hypertrophy of adenoids was previously demonstrated. Snoring and sleep apnea were present before GH treatment, and did not increase during therapy. Four months later she died at home suddenly in the morning. Case 2: This patient was a 6.3-yr-old boy. He was born at term after an uneventful pregnancy. At the age of 6 yr, his weight was at 144% of his ibw. He showed reduced GH secretion during provocation tests, and GH therapy was started (0.20 mg/kg per week). The previously reported nocturnal respiratory impairment had worsened after beginning GH administration. Tonsils and adenoids hypertrophy were noted. At the age of 6.3 yr he died at home in the morning following an acute crisis of apnea. These additional cases seem to confirm that some children with PWS may be at risk of sudden death at the beginning of GH therapy.

Abstract
Respiratory diseases contribute significantly to perioperative morbidity and mortality. Severe pulmonary complications usually emerge postoperatively. To minimise pulmonary risk, the perioperative evaluation of lung function is of major significance, allowing the identification of patient and surgery-related risk factors. In particular, the significance of the intraoperative assessment of lung function has gained in importance over the last few years. The following article describes the possibilities and frontiers of the perioperative assessment of lung function, and focuses especially on the significance of preoperative pulmonary function tests and the intraoperative interpretation of respiratory pressure, flow, and volume loops.

Abstract
Medical and surgical treatment are able to improve symptoms in patients with gastroesophageal reflux disease (GERD). The aim of this study was to evaluate the outcome following laparoscopic antireflux surgery in GERD patients with primary respiratory-related symptoms and to investigate the quality of life index before and after therapy. Three hundred thirty-eight consecutive patients underwent surgical treatment for GERD-induced symptoms. Of this group 126 patients had primary respiratory symptoms related to GERD. All patients were studied by means of a symptom questionnaire, endoscopy, esophageal manometry, 24-hour esophageal pH monitoring, and a barium esophagogram. In addition, the quality of life was measured by the means of the Gastrointestinal Quality of Life Index (GIQLI). All patients had medical therapy with proton pump inhibitors preoperatively. A laparoscopic fundoplication was performed in all patients. The outcome was assessed 3 and 12 months postoperatively. Following surgery, all respiratory symptoms were significantly improved. While GIQLI was highly impaired before surgical therapy, a significant improvement of quality of life was obtained. Because medical treatment is likely to fail in GERD patients with respiratory symptoms, the need for surgery arises and may be the only successful treatment in the long term. Quality of life was significantly improved by surgical treatment.

Abstract
Patients with acute upper respiratory tract infection (URTI) have been shown to be hyperreactive to inhaled tussigens such as citric acid and capsaicin, and the authors propose that this may be due to an increased sensitivity of airway receptors that mediate cough. In recent studies we have demonstrated that cough may be induced by vibration of the airway at the level of the throat or chest in patients with URTI but that the same stimuli induce little or no cough in healthy subjects. The difference between the patients with URTI and healthy subjects in their response to airway vibration may be explained on the basis of hyperreactivity of airway sensory receptors. We propose that the model of cough induced by airway vibration may be useful for studies on the pathophysiology and pharmacology of airway hyperreactivity in acute cough. The airway vibration model of cough may have some advantages over inhaled tussigens as the stimulus is easily controlled and the method is safe for use in children.

The Wheezing Illnesses Study Leidsche Rijn (WHISTLER) was initiated in December 2001 as a single-centre prospective birth cohort study and will include a population-based sample of at least 2000 healthy newborns. The aims of WHISTLER are to investigate determinants for wheezing illnesses (including neonatal lung function, viral infections, asthma-susceptibility genes and endotoxin exposure) and to derive a comprehensive risk score, that is appropriate for use in primary health care and allows for efficient planning of early preventive strategies. Baseline examination includes a questionnaire evaluating known risk factors for wheezing illnesses; anthropometric measurements; measurements of infant and parental lung function; and sampling of infant and parental DNA. Participants will be followed for respiratory events using data from a daily respiratory symptom questionnaire; visits to the general practitioner (primary health care visits, drugs prescriptions and hospital referral); viral sampling during wheezing episodes; and house dust sampling. Based on actual neonatal care practice and embedded in a larger epidemiological study, the Utrecht Health Project, WHISTLER will provide an unique framework to address issues in childhood respiratory disease that are currently insufficiently understood. In particular, WHISTLER will provide a well-balanced view on the prognostic power of neonatal lung function and genetic and environmental factors (including viral infections and endotoxin exposure) to predict wheezing illnesses from birth to young adulthood and beyond. In the scope of prevention, WHISTLER is expected to support the design of solid based prevention measures to reduce respiratory morbidity, mortality and associated costs, and to improve quality of life.

Abstract
BACKGROUND Significant alterations occur in the pulmonary system during pregnancy, which primarily serve to meet the increased oxygen consumption by the growing fetus. When pregnancy is complicated by a respiratory tract disorder such as asthma, cystic fibrosis or tobacco-related respiratory complications the peripartum management (both obstetric and anesthetic) may become challenging. TECHNIQUE Regional anesthesia remains the technique of choice for these parturients because airway manipulation and endotracheal intubation are avoided. CONCLUSION When providing labor analgesia to parturients with asthma, cystic fibrosis, and tobacco-related respiratory disorders every effort should be made to reduce the likelihood of high (thoracic) levels of analgesia and/or anesthesia and subsequent airway compromise.

Abstract
BACKGROUND The main goals of diagnostic cardiac catheterization (DCC) in infants are to evaluate the anatomy and physiology of congenital and acquired cardiac defects while maintaining normal respiratory and hemodynamic variables. The aims of anesthesia for infants undergoing DCC are to prevent pain and movement during the procedure. General anesthesia (GA) or deep sedation could have undesirable respiratory and hemodynamic effects for conducting such studies. Furthermore, GA is associated with increased risks, especially in high-risk infants. Spinal anesthesia (SA) is a successful alternative to GA in surgery on infants with a history of prematurity and respiratory problems, with minimal respiratory and hemodynamic changes. METHODS We studied whether those advantages were applicable to DCC, and used a predetermined SA protocol in a cohort of 12 infants with compromised respiratory status. Success rate, study completion, complications, hemodynamic and respiratory effects and recovery profile were recorded. RESULTS Failure rate was significantly higher in infants older than 6 months. There was no significant difference between baseline and intraprocedure hemodynamic and respiratory parameters. The time to discharge was relatively short (33 +/- 12 min). CONCLUSIONS Spinal anesthesia apparently provides stable hemodynamics and respiratory variables, rapid recovery and discharge time, and may be a viable alternative to GA or deep sedation in high-risk infants <6 months old undergoing DCC.

Abstract
OBJECTIVES To describe the comorbidity of visual impairment and disability among patients hospitalized for systemic illness and to discuss rehabilitation. DESIGN Retrospective study. SETTING Hospital-based, academic tertiary medical center with referring neurology, ophthalmology, and rehabilitation units. PARTICIPANTS Ninety-three hospitalized patients referred to the low vision rehabilitation clinic primarily by the physical medicine and rehabilitation and neurology units. INTERVENTIONS Measurements of best-corrected visual acuity and other visual function testing. Referrals were made for prescriptive glasses, assistive devices, rehabilitation, resources, and ophthalmologic evaluation. MAIN OUTCOME MEASURES Specialized services, presence of comorbidities, and visual function measurements. RESULTS The mean admitting visual acuity revealed a moderate visual impairment. The primary diagnosis for admission (51%) was cerebrovascular accidents. There was a mean of 3.5 other comorbidities. CONCLUSIONS The majority of patients admitted to the hospital for systemic diseases also had visual impairments. In many patients, this visual disability (either from the systemic and/or ocular disease) interfered with their activities of daily living.

Abstract
OBJECTIVE Juvenile localized scleroderma is usually considered a disease that is confined to the skin and subcutaneous tissue. We studied the prevalence and clinical features of extracutaneous manifestations in a large cohort of children with juvenile localized scleroderma. METHODS Data from a multinational study on juvenile scleroderma was used for this in-depth study. Clinical features of patients with extracutaneous manifestations were compared with those of patients who had exclusively skin involvement. RESULTS Seven hundred fifty patients entered the study. One hundred sixty-eight patients (22.4%) presented with a total of 193 extracutaneous manifestations, as follows: articular (47.2%), neurologic (17.1%), vascular (9.3%), ocular (8.3%), gastrointestinal (6.2%), respiratory (2.6%), cardiac (1%), and renal (1%). Other autoimmune conditions were present in 7.3% of patients. Neurologic involvement consisted of epilepsy, central nervous system vasculitis, peripheral neuropathy, vascular malformations, headache, and neuroimaging abnormalities. Ocular manifestations were episcleritis, uveitis, xerophthalmia, glaucoma, and papilledema. In more than one-fourth of these children, articular, neurologic, and ocular involvements were unrelated to the site of skin lesions. Raynaud's phenomenon was reported in 16 patients. Respiratory involvement consisted essentially of restrictive lung disease. Gastrointestinal involvement was reported in 12 patients and consisted exclusively of gastroesophageal reflux. Thirty patients (4%) had multiple extracutaneous features, but systemic sclerosis (SSc) developed in only 1 patient. In patients with extracutaneous involvement, the prevalence of antinuclear antibodies and rheumatoid factor was significantly higher than that among patients with only skin involvement. However, Scl-70 and anticentromere, markers of SSc, were not significantly increased. CONCLUSION Extracutaneous manifestations of juvenile localized scleroderma developed in almost one-fourth of the children in this study. These extracutaneous manifestations often were unrelated to the site of the skin lesions and sometimes were associated with multiple organ involvement. The risk of developing SSc was very low. This subgroup of patients with juvenile localized scleroderma should be evaluated extensively, treated more aggressively, and monitored carefully.

Abstract
The aging process in men is accompanied by a progressive decline in serum testosterone levels. In addition to chronological aging, the various illnesses occurring in mid- to late-adult life and the medications used to treat them further contribute to lowering circulating testosterone levels. Any acute severe illness produces hypogonadotrophic hypogonadism; but also chronic illnesses, such as diabetes, cardiovascular disease and hypertension, lifestyle habits, such as tobacco and alcohol intake, and nutritional factors, from malnutrition to obesity, account for and accentuate the age-related decline in serum androgen levels. These issues are reviewed in a clinical perspective.

Abstract
OBJECTIVES To review prenatal findings, short- and long-term outcomes of giant omphaloceles (GO) managed at a single institution (1996-2001). METHODS Prenatal findings and early postnatal outcomes were retrospectively reviewed. Clinical short- and long-term outcomes were analyzed in eight and five children respectively. Parents and physicians of the children were surveyed by written questionnaires about the children's subsequent health issues. (IRB 2002-2-2683). RESULTS Seventeen pregnancies with GO were identified: Eight fetuses were live born, four ended in (terminations), two died in utero and three were lost to follow-up. Live-born fetuses had prenatal ascites, extreme levocardia and were delivered by cesarean section at a mean of 37 weeks' gestation with a mean birth weight of 2903 g. All neonates required intubation. Two infants (2/8) died within one year. Four of the six survivors had respiratory insufficiency with a mean ventilation time of 76 days. Respiratory and feeding problems complicated the early neonatal course. Long-term follow-up was available for five patients (mean age of 33.2 months). Asthma, recurrent pulmonary infections, feeding problems, gastroesophageal reflux and failure to thrive were the major problems. CONCLUSIONS Respiratory and feeding problems were the most common neonatal and long-term medical management issues. Parents need to be counseled prenatally about the probability of multiple surgeries and long hospitalization following birth.
