INTRODUCTION: Hereditary fibrosing poikiloderma with tendon contractures, myopathy and pulmonary fibrosis (POIKTMP) is a recently described, extremely rare, entity belonging to the spectrum of inherited poikilodermas. It is provoked by a mutation of the FAM111B gene. Respiratory involvement has never been fully described but usually involves a restrictive respiratory pattern. We present here a case of pulmonary fibrosis associated with POIKTMP and describe the clinical, functional, radiological and evolutionary characteristics...

BACKGROUND: Phase 3 trials have shown that nintedanib reduces the decline in forced vital capacity (FVC) in patients with mild-to-moderate idiopathic pulmonary fibrosis (IPF) with acceptable safety profiles; however, its effects on advanced IPF are unclear. We investigated the efficacy and safety of nintedanib in patients with advanced IPF. METHODS: Prospective data were obtained from 108 IPF patients administered at least one dose of nintedanib. Of these patients, 47...

Diffuse pulmonary ossification (DPO) is an uncommon diffuse lung disease characterized by metaplastic bone formation in the lung parenchyma and is rarely diagnosed in life. While DPO usually occurs as a secondary disease, idiopathic cases are extremely rare. We describe three cases of idiopathic DPO, two of which were definitively diagnosed by surgical lung biopsy. One case was observed in a 43-year-old man with a history of recurrent pneumothorax who developed pneumothorax after the surgical biopsy. Few reports have described cases of DPO with recurrent pneumothorax; however, pneumothorax should be considered as a potential complication when such patients are encountered...

OBJECTIVE: We explored the relationship between preoperative 18 F-FDG-PET parameters, tumor necrosis, and microvessel density (MVD) in patients with pulmonary adenocarcinomas. METHODS: A total of 164 patients, who underwent surgical resection for lung adenocarcinoma, were reviewed retrospectively. The maximum standardized uptake value (SUVmax ), peak SUV corrected for lean body mass (SULpeak ), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) values were measured by preoperative 18 F-FDG-PET...

Under resting normoxic conditions, the healthy lung has ample oxygen uptake capacity relative to oxygen demand, but during exercise, increased oxygen demand and utilization become increasingly dependent on ventilation-perfusion matching. A mathematical model is used to investigate the effect of pulmonary flow heterogeneity, as characterized by the coefficient of variation (CV) of capillary blood flow, on pulmonary oxygen uptake in exercise. The model reveals that any level of heterogeneity up to a CV of 3 is consistent with the observed level of arterial oxygen tension under resting conditions, but that such high levels of heterogeneity are incompatible with the levels of oxygen uptake observed during exercise...

Objectives: Radiation pneumonitis (RP) can be an adverse complication of radiotherapy (RT) and can limit the application of the already planned radiation dose. It is often associated with RT of lung carcinoma and is occasionally caused by radiation therapy of breast carcinoma and lymphomas located in the mediastinum. Positron emission tomography/computed tomography (PET/CT) emerges lately as a prospective modality for early diagnostics of RP. The aim of this study was to summarize the initial data from diagnostic application of PET/CT in patients suspicious of RP and to derive criteria, which can help differentiate RP from early recurrence of the disease and/or residual tumor...

AIM: The lungs-and particularly the alveolar-capillary membrane-may be sensitive to continuous flow (CF) and pulmonary pressure alterations in heart failure (HF). We aimed to investigate long-term effects of CF pumps on respiratory function. METHODS AND RESULTS: We conducted a retrospective study of patients with end-stage HF at our institution. We analysed pulmonary function tests [e.g. forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1 )] and diffusing capacity of the lung for carbon monoxide (DLCO ) from before and after left ventricular assist device (LVAD) implantation and compared them with invasive haemodynamic studies...

BACKGROUND: While cystic fibrosis (CF) lung disease is generally considered to be an obstructive disorder, other pulmonary function patterns (PFP) may occur. Furthermore, little is known about possible associations between PFP and genotype or phenotypical characteristics. METHODS: Cross-sectional study including CF patients aged 16 years or more, identifying different PFP and exploring associations between PFP and genotype or phenotypical characteristics. RESULTS: Obstructive PFP was most prevalent in our population (n = 80), comprising obstructive lung disease (62...

Quantitative imaging in lung cancer is a rapidly evolving modality in radiology that is changing clinical practice from a qualitative analysis of imaging features to a more dynamic, spatial, and phenotypical characterization of suspected lesions. Some quantitative parameters, such as the use of 18F-FDG PET/CT-derived standard uptake values (SUV), have already been incorporated into current practice as it provides important information for diagnosis, staging, and treatment response of patients with lung cancer...

The motive behind present work was to discover a solution for overcoming the problems allied with deprived oral bioavailability of salbutamol sulphate (SS) due to its first pass hepatic metabolism, shorter half life and systemic toxicity at high doses. Pulmonary delivery provides alternative route of administration to avoid hepatic metabolism of SS, moreover facilitated diffusion and prolonged retention can be achieved by incorporation into liposomes. Liposomes were prepared by thin film hydration technique using 32 full factorial design and formulation was optimized based on the vesicle size and percent drug entrapment (PDE) of liposomes...

Mesothelioma is a rare tumor of the pleura, peritoneum, pericardium or tunica vaginalis. About 2,500 cases are diagnosed annually in the United States. Mesothelioma often presents with pleuritic chest pain and dyspnea related to local invasion; distal metastasis and lymphadenopathy at the time of diagnosis is rare. Pericardial involvement in mesothelioma is related to direct invasion of the tumor. We here present a 71 year-old-male who presented with pleuritic chest pain and dyspnea, noted to have diffuse ST-segment elevation in EKG and cardiac tamponade physiology on 2D echocardiogram in who imaging subsequently revealed left upper lung mesothelioma...
