Idiopathic pulmonary fibrosis (IPF) is a quality-of-life-altering and life-shortening lung disease manifested by physiologic restriction, hypoxemia and progressive shortness of breath. Despite nearly 30 years of investigation, the median survival for patients with this disease remains dismal at approximately 3 years from the time of diagnosis. Recent investigations have identified a number of potential molecular therapeutic targets for IPF that include endothelin-1 and other fibrogenic cytokines. Bosentan, a nonselective endothelin receptor antagonist approved in the USA and Europe for the treatment of patients with pulmonary arterial hypertension, is currently undergoing evaluation as a potential therapy for IPF. A recently completed multinational, placebo-controlled trial failed to show a beneficial impact of bosentan on the primary end point, but results from a hypothesis-generating, post hoc analysis of data from this trial have prompted an assessment of the drug for efficacy in a selected subgroup of IPF patients - those with biopsy-proven IPF and little radiographic honeycombing. Results from this trial are anticipated in 2009.

Pulmonary alveolar proteinosis (PAP) has been associated with the immunosuppressant sirolimus in transplant patients. PAP is a progressive lung disease characterized by the accumulation of surfactant-like material in the lungs leading to decreased pulmonary function with shortness of breath and cough as common symptoms. We report a rare case of sirolimus-associated PAP in a kidney transplant recipient with a history of end-stage renal disease secondary to haemolytic uraemic syndrome (HUS) and review of the literature. Discontinuation of sirolimus and initiation of tacrolimus led to resolution of PAP without recurrence of HUS.

This paper summarizes "Respiratory Issues in Confined Feeding Operations," a panel discussion at the Agricultural Safety and Health Council of America/National Institute for Occupational Safety and Health conference, "Be Safe, Be Profitable: Protecting Workers in Agriculture," Dallas/Fort Worth, Texas, January 27-28, 2010. Occupational exposure to confined animal feeding operations is associated with cough, wheezing, and shortness of breath. Published data shows that 20% to 40% of hog confinement workers experience such symptoms, although most are able to continue working in this industry. Endotoxin is one component of hog barn dust that is associated with respiratory disease in workers. Endotoxin levels on cattle feedlots can also be in the range linked with occupational lung disease. The cattle industry has not yet prepared guidance documents for producers, in part because much less is known about the prevalence of lung disease in its workers. However, the pork industry provides information for pork producers on reducing their respiratory health risks through a multifaceted approach, including the use of respirators. Some jobs cannot be done safely without respiratory protection, such as entering manure pits. It is less clear for other jobs when respirators should be worn. Use of respiratory protection should be considered but not mandated for all persons working in close proximity to livestock in dusty conditions. A respiratory protection program may also serve as a cost effective biosecurity measure to protect animals from human pathogens such as influenza virus. Proper design and management of barn ventilation systems is critical for maintaining temperature and humidity levels for optimal animal growth; as well as decreasing the level of gases and respirable dusts. The pork and the cattle industries support occupational health and safety; however, the governmental guidance and recommendations for such programs are limited for the agricultural industries as a whole. The industries should lead the way in the effort to improve respiratory protection for workers. Overall, a team approach that includes input from managers, workers, and veterinarians is important for the reduction of respiratory hazards on livestock farms.

Bronchiolitis obliterans organizing pneumonia is an inflammatory lung disease involving the distal bronchioles, respiratory bronchioles, bronchiolar ducts and alveoli. Its cause is generally unknown, but there are several known causes and associated systemic diseases. The clinical features include cough, shortness of breath and bilateral crackles. The vital capacity is slightly decreased, and the diffusing capacity is moderately to severely decreased. The high-resolution chest CT scan shows bilateral ground-glass opacities with air bronchograms and triangular, pleura-based opacities. Corticosteroid therapy is the best treatment option. The outcome of patients suffering from bronchiolitis obliterans organizing pneumonia is good, as up to 80% of individuals will be cured.

Emphysema is a progressive, disabling disease. Emphysematous bullae form as a result of local areas of alveolar weakness and parenchymal remodeling. They grow as a result of preferential inflation during inspiration and elastic recoil of the surrounding lung tissue. Isolated apical bullae can be a consequence of illicit drug use, as was suspected in this patient. In the case of cocaine and marijuana smoking, direct drug toxicity or drug-induced vasoconstriction presumably contributes to bullae development. LVRS is often used to treat patients with bullae and severe underlying emphysema, although these patients are difficult to assess and their disease course is hard to predict. LVRS is associated with a higher morbidity and mortality. The best candidates for surgery have enlarged, well-localized bullae and minimal underlying lung disease. Early postoperative results include relief of shortness of breath, improved lung function, increased energy level and physical mobility, and improved ability to function during daily activities. LVRS may decrease the need for supplemental oxygen as soon as a few weeks after surgery, and benefits may be sustained for years. The best results are seen in patients with large bullae that cause the greatest compression of almost normal underlying lung. However, clinical and symptomatic improvement may be greater than actual spirometric measurements.

Pulmonary alveolar microlithiasis (PAM) is an uncommon lung disease characterized by accumulation of intraalveolar calcifications. The disease can be diagnosed based on the radiological findings. We present a 27-year-old women with five-year history of shortness of breath. She was diagnosed with PAM due to the presence of the characteristic chest X-ray and thorax computed tomography (CT) findings. We performed (18)F-fluorodeoxyglucose (FDG)-PET/CT imaging in order to detect any evidence of inflamation in the lung before deciding an anti-inflammatory treatment. The lung regions with dense calcifications revealed low FDG uptakes (SUVmax: 2.7) and the lung regions without calcifications showed lower FDG uptakes. No further treatment modality was planned besides inhaler salbutamol. Herein, we discuss this rare entity with literature search.

Pleuroparenchymal fibroelastosis (PPFE) is a rare condition characterised by predominantly upper lobe pleural and subjacent parenchymal fibrosis, the latter being intra-alveolar with accompanying elastosis of the alveolar walls. The aim of this study was to review cases fulfilling published imaging and histological criteria, and identify any common clinical features that may suggest an underlying aetiology for a condition that has previously been regarded as idiopathic. Of 12 patients (seven females, median age 57 yrs), the presenting symptoms were shortness of breath (11 out of 12 patients) and dry cough (six out of 12 patients). Seven patients reported recurrent infections during the course of their disease. Five demonstrated nonspecific autoantibody positivity. Two patients had a family history of interstitial lung disease (ILD). High-resolution computed tomography features of lung disease remote from the pleuroparenchymal changes were present in six out of 12 patients (coexistent fibrosis, n=5; bronchiectasis, n=1). Of seven patients with tissue sampled from the lower lobes, four patients showed less intense PPFE changes (one with additional features of hypersensitivity pneumonitis) and three showed usual interstitial pneumonia. PPFE is a distinct clinicopathological entity, with clinical data suggesting a link to recurrent pulmonary infection. Genetic and autoimmune mechanisms may also contribute to the development of these changes. PPFE may also present with more diffuse involvement than previously reported, and coexist with different patterns of ILD.

Persons with HIV infection have a higher risk of infectious pulmonary complications, chronic obstructive pulmonary disease, lung cancer, pulmonary hypertension, and pulmonary fibrosis than individuals not infected with HIV. Herein, we describe the clinical course of a patient with longstanding and well-controlled HIV infection and multiple previous pneumothoraces who presented to medical attention with insidious onset of shortness of breath and was diagnosed with vanishing lung syndrome (VLS). The VLS or giant bullous emphysema is a distinct clinical syndrome characterized by large bullae, predominantly in the upper lobes, occupying at least one third of the hemithorax and compressing surrounding normal lung parenchyma. It is a progressive disorder that typically occurs in young men, the majority of whom are smokers. As people with HIV/AIDS are now surviving well into middle age and beyond, clinicians are more likely to encounter VLS and severe obstructive lung disease, which are potentially fatal but preventable conditions.

A young, previously well primigravida presented a few hours after a short labour with sudden onset chest pain, shortness of breath and odynophagia. She had subcutaneous emphysema but did not have significant cardiorespiratory compromise. She was found to have a spontaneous pneumomediastinum, likely secondary to raised intrathoracic pressure during labour. Similar cases have been reported previously, however there are often risk factors associated such as pre-existing lung disease and illicit drug use for which this patient did not have a significant history. The patient made a speedy recovery without requiring invasive management, as is the case for most patients documented in the literature. Consideration should be given to subsequent labours for this patient to minimise excessive intrathoracic pressure, however recurrence is rarely documented. This case is useful for healthcare professionals in assessing patients with chest pain as a reminder that unusual presentations can be diagnosed through thorough history and examination.
