Hypersensitivity pneumonitis (HP) is a complex pulmonary disorder mediated by the immune system and caused by various inhaled antigens against which the subject has previously been sensitized. In about 50% of the cases, the antigen is not identified. Identification and removal of the eliciting antigen is important for the prognosis. We report two cases of HP caused by molds and atypical mycobacteria isolated from wind instruments. We present the first case of HP caused by bassoon playing and another case of HP caused by molds in a trombone...

BACKGROUND: Pasteurella multocida is a Gram-negative bacterium that causes economically significant infections of a broad range of animal species. Pneumonic and septicaemic pasteurellosis caused by this bacterium remain important problems in pigs, cattle, and water buffaloes in Thailand. The aim of this study was to characterise the virulence-associated gene profiles and to develop an OmpA molecular typing scheme for classifying 191 bovine and porcine isolates of P. multocida collected between 1989 and 2012 in Thailand using polymerase chain reactions (PCRs), nucleotide sequencing, and sequence and structural bioinformatics analyses...

Francisella tularensis is a gram-negative coccobacillus that causes a condition commonly referred to as tularemia. There has been a dramatic increase in tularemia cases reported in South Dakota, many of which were challenging to diagnose due to atypical clinical manifestations. We describe an interesting case of pneumonic tularemia and summarize six similar cases, several of which presented with lung nodules suggestive of malignancy. According to the literature, this is only the third outbreak of pneumonic tularemia reported in the U...

Background: Occupational exposure to methylene bisphenyl isocyanate (MDI) presents serious worker health concerns as it may lead to short- and long-term health effects such as asthma, airway irritation, hypersensitivity pneumonitis, and irritation of skin and mucous membranes. While studies of worker isocyanate exposures during vehicle painting activities are widespread, few studies have investigated the spray-on truck bed-liner (STBL) industry. The purpose of this study was to determine the effectiveness of several ventilation system variables and process characteristics in controlling MDI concentrations in the STBL industry...

Lung disease is one of the most common causes of extra-articular morbidity and mortality in patients with rheumatoid arthritis (RA). Development of pulmonary manifestations may be due to the systemic disease itself; to serious respiratory adverse events such as pneumonitis and infections secondary to therapy; or to lifestyle habits such as smoking. Rheumatologists often need to make important treatment decisions and plan future care in RA patients with respiratory comorbidities, despite the absence of clear evidence or consensus...

PURPOSE: To cover the microscopic tumor spread in squamous cell carcinoma of the esophagus (SCC), longitudinal margins of 3-4 cm are used for radiotherapy (RT) protocols. However, smaller margins of 2-3 cm might be reasonable when advanced diagnostic imaging is integrated into target volume delineation. Purpose of this study was to compare the dose distribution and deposition to the organs at risk (OAR) for different longitudinal margins using a DVH- and NTCP-based approach. METHODS: Ten patients with SCC of the middle or lower third were retrospectively selected...

Upper tracheal malignancies are rare, and long-term survival is even rarer, especially among the unresectable malignancies. A 66-year-old chronic smoker was diagnosed as a locally advanced, non-metastatic squamous cell carcinoma of the upper trachea. Being unresectable, he was treated with six cycles of concurrent weekly cisplatin and three-dimensional conformal radiotherapy to a dose of 60 Gy in 30 fractions over 6 weeks. Follow-up imaging at 6 and 12 months revealed no disease. Our patient is presently 36 months post-treatment and is disease free without tracheal necrosis, fistula or radiation pneumonitis but developed hypothyroidism and is presently euthyroid...

Immunotherapy is becoming a standard of care for many cancers. Immune-checkpoint inhibitors (ICI) can generate immune-related adverse events. Interstitial lung disease (ILD) has been identified as a rare but potentially severe event.Between December 2015 and April 2016, we conducted a retrospective study in centres experienced in ICI use. We report the main features of ICI-ILD with a focus on clinical presentation, radiological patterns and therapeutic strategies.We identified 64 (3.5%) out of 1826 cancer patients with ICI-ILD...

Taxanes are often used in the treatment of many types of cancers. Side effects of docetaxel are not as well documented as paclitaxel, but both can cause pulmonary injury. We present a dramatic case of a patient being treated for prostatic adenocarcinoma with docetaxel who presented with interstitial pneumonitis and responded dramatically to the early treatment with corticosteroids. This case is important as it reveals the side effects of docetaxel administration without administration of other chemotherapeutic agents, and it illustrates the importance of early diagnosis and treatment of docetaxel-induced interstitial pneumonitis...

Radiotherapy is the ionizing radiation used for treatment of cancer and other diseases. Although radiotherapy is the major treatment for cancer, a lot of patients do not undergo radiation due to associated risks such as radiation pneumonitis, cardiovascular complications, development of secondary tumor, and lymphedema. However, the advantages of nanotechnology provide a unique potential to enhance radiotherapeutic performance, in particular by utilizing gold nanoparticles (Au NPs). In this review, we briefly describe the current direction of research towards the use of Au NPs for radiotherapeutic enhancement, combination, monitoring and in side effect reductions...

Sarcoid like reaction is a well-known entity that occurs as a consequence to several malignancies or their therapies. Immunotherapy has gained a lot of interest in the past few years and has recently gained approval as first line therapy in multiple advanced stage malignancies. Pneumonitis has been described as complication of such therapy. Granulomatous inflammation has been only rarely reported subsequent to immunotherapy. We describe a case of granulomatous inflammation reactivation affecting the lungs in a patient previously exposed to Pembrolizumab and have evidence of a distant granulomatous infection...

BACKGROUND: Adverse events (AEs) related to medical treatments in non-small cell lung cancer (NSCLC) are frequent and need an appropriate costing in health economic models. Nevertheless, data on costs associated with AEs in NSCLC are scarce, particularly since the development of immunotherapy with specific immune-related AEs. OBJECTIVE: To estimate the costs of grades 3 and 4 AEs related to NSCLC treatments including immunotherapy in France. METHODS: Grades 3 and 4 AEs related to treatment and reported in at least 1% of patients in Phase III clinical trials for erlotinib, ramucirumab plus docetaxel, docetaxel, pemetrexed plus carboplatin plus bevacizumab, platinum-based chemotherapies, nivolumab and pembrolizumab were identified...

Granulomatous lung diseases are a heterogeneous group of disorders that have a wide spectrum of pathologies with variable clinical manifestations and outcomes. Precise clinical evaluation, laboratory testing, pulmonary function testing, radiological imaging including high-resolution computed tomography and often histopathological assessment contribute to make a confident diagnosis of granulomatous lung diseases. Differential diagnosis is challenging, and includes both infectious (mycobacteria and fungi) and noninfectious lung diseases (sarcoidosis, necrotising sarcoid granulomatosis, hypersensitivity pneumonitis, hot tub lung, berylliosis, granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, rheumatoid nodules, talc granulomatosis, Langerhans cell histiocytosis and bronchocentric granulomatosis)...

BACKGROUND: Chemoradiotherapy is the standard treatment for locally advanced non-small cell lung cancer (NSCLC); however, it is disputed whether this treatment is suitable for patients aged ≥75. This study was conducted to determine the maximum tolerated dose (MTD) of pemetrexed for use in concurrent radiotherapy for elderly patients with locally advanced non-squamous NSCLC. METHODS: The eligibility criteria were as follows: aged ≥75 with inoperable stage IIIA or IIIB non-squamous NSCLC, no history of chemotherapy or radiotherapy, a performance status of 0 or 1, and adequate organ function...
