Intermediate care units : Recommendations on facilities and structure.

A growing number of patients with increasingly complex or specialized diseases are being treated in hospitals worldwide. The treatment requirements of some of these patients are exceeding the capacity of standard nursing units. However, the severity of these diseases or the treatment requirements for these specific clinical pictures do not always justify admission to an intensive care unit.

The European Respiratory Society spirometry tent: a unique form of screening for airway obstruction.

In order to raise public awareness of the importance of early detection of airway obstruction and to enable many people who had not been tested previously to have their lung function measured, the European Lung Foundation and the European Respiratory Society (ERS) organised a spirometry testing tent during the annual ERS Congresses in 2004-2009. Spirometry was performed during the ERS Congresses in volunteers; all participants answered a simple, brief questionnaire on their descriptive characteristics, smoking and asthma. Portable spirometers were freely provided by the manufacturer.

Bronchoscopic lung-volume reduction with Exhale airway stents for emphysema (EASE trial): randomised, sham-controlled, multicentre trial.

Background: Airway bypass is a bronchoscopic lung-volume reduction procedure for emphysema whereby transbronchial passages into the lung are created to release trapped air, supported with paclitaxel-coated stents to ease the mechanics of breathing. The aim of the EASE (Exhale airway stents for emphysema) trial was to evaluate safety and efficacy of airway bypass in people with severe homogeneous emphysema.

Methods: We undertook a randomised, double-blind, sham-controlled study in 38 specialist respiratory centres worldwide.

Design of the exhale airway stents for emphysema (EASE) trial: an endoscopic procedure for reducing hyperinflation.

Background: Airway Bypass is a catheter-based, bronchoscopic procedure in which new passageways are created that bypass the collapsed airways, enabling trapped air to exit the lungs. The Exhale Airway Stents for Emphysema (EASE) Trial was designed to investigate whether Exhale® Drug-Eluting Stents, placed in new passageways in the lungs, can improve pulmonary function and reduce breathlessness in severely hyperinflated, homogeneous emphysema patients (NCT00391612).

Methods/design: The multi-center, randomized, double-blind, sham-controlled trial design was posted on http://www.

Breathing pattern and chest wall volumes during exercise in patients with cystic fibrosis, pulmonary fibrosis and COPD before and after lung transplantation.

Background: Pulmonary fibrosis (PF), cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD) often cause chronic respiratory failure (CRF).

Methods: In order to investigate if there are different patterns of adaptation of the ventilatory pump in CRF, in three groups of lung transplant candidates with PF (n=9, forced expiratory volume in 1 s (FEV(1))=37+/-3% predicted, forced vital capacity (FVC)=32+/-2% predicted), CF (n=9, FEV(1)=22+/-3% predicted, FVC=30+/-3% predicted) and COPD (n=21, FEV(1)=21+/-1% predicted, FVC=46+/-2% predicted), 10 healthy controls and 16 transplanted patients, total and compartmental chest wall volumes were measured by opto-electronic plethysmography during rest and exercise.

Results: Three different breathing patterns were found during CRF in PF, CF and COPD.

Risk stratification of solitary pulmonary nodules by means of PET using (18)F-fluorodeoxyglucose and SUV quantification.

Purpose: (18)F-fluorodeoxyglucose (FDG) PET is the most accurate imaging modality in characterizing a solitary pulmonary nodule (SPN). Besides visual image interpretation, semiquantitative analysis using standardized uptake values (SUV) is performed to improve diagnostic accuracy. Mostly, an SUV threshold of 2.

Airway bypass treatment of severe homogeneous emphysema: taking advantage of collateral ventilation.

Airway bypass is being investigated as a new form of minimally invasive therapy for the treatment of homogeneous emphysema. It is a bronchoscopic catheter-based procedure that creates transbronchial extra-anatomic passages at the bronchial segmental level. The passages are expanded, supported with the expectation that the patency is maintained by paclitaxel drug-eluting airway bypass stents.

Impaired detection of Mycobacterium tuberculosis immunity in patients using high levels of immunosuppressive drugs.

We have previously shown, in renal transplant recipients on maintenance immunosuppression, that a whole-blood assay was superior in detecting immunity towards purified protein derivative (PPD) compared with skin testing. As blood tests may have limitations during high-dose immunosuppression therapy, the present study was aimed at characterising the effect of high immunosuppressive drug levels on PPD-specific T-cell immunity. PPD-reactive CD4 T-cells from 13 renal transplant recipients were longitudinally quantified by the induction of cytokines using flow cytometry.

[Massive pleural effusion complicating chronic pancreatitis. Treatment by endoscopic closure of a pancreatic-mediastinal fistula].

History And Clinical Findings: A 53-year-old man was admitted because of anuria, dyspnea and a septic temperature. The patients' history included chronic alcoholism, chronic pancreatitis, COPD and a right nephrectomy because of nephrolithiasis. Urosepsis was initially suspected.

Low-dose MDCT for surveillance of patients with severe homogeneous emphysema after bronchoscopic airway bypass.

Objective: The purpose of this study was to evaluate the usefulness of low-dose MDCT for radiologic monitoring of patients who have undergone placement of bronchial stents for airway bypass.

Subjects And Methods: In a prospective study, seven patients underwent MDCT according to a low-dose protocol (40 mAs, 120 kVp) before and after stent placement. The positions of the stents in the segmental bronchi were analyzed and compared with the bronchoscopic findings, which were reference standard.

Effect of preoperative chemoradiation in addition to preoperative chemotherapy: a randomised trial in stage III non-small-cell lung cancer.

Background: Preoperative chemotherapy improves survival in patients with stage III non-small-cell lung cancer (NSCLC) amenable to resection. We aimed to assess the additional effect of preoperative chemoradiation on tumour resection, pathological response, and survival in these patients.

Methods: Between Oct 1, 1995, and July 1, 2003, patients with stage IIIA-IIIB NSCLC and invasive mediastinal assessment from 26 participating institutions of the German Lung Cancer Cooperative Group (GLCCG) were randomly assigned to one of two treatment groups.

Matrix metalloproteinase 1 (MMP1) is associated with early-onset lung cancer.

Matrix metalloproteinases (MMP) play a key role in the breakdown of extracellular matrix and in inflammatory processes. MMP1 is the most highly expressed interstitial collagenase degrading fibrillar collagens. Overexpression of MMP1 has been shown in tumor tissues and has been suggested to be associated with tumor invasion and metastasis.

Early onset lung cancer, cigarette smoking and the SNP309 of the murine double minute-2 (MDM2) gene.

The polymorphism SNP309 (rs2279744) in the promoter region of the MDM2 gene has been shown to alter protein expression and may play a role in the susceptibility to lung cancer. The MDM2 protein is a key inhibitor of p53 and several mechanisms of MDM2/p53 interactions are presently known: modulating DNA-repair, cell-cycle control, cell growth and apoptosis.We used 635 Caucasian patients diagnosed with lung cancer before 51 years of age and 1300 healthy gender and age frequency matched population Caucasian controls to investigate the association between the MDM2 SNP309 and the risk of developing early onset lung cancer.

Do genetic factors protect for early onset lung cancer? A case control study before the age of 50 years.

Background: Early onset lung cancer shows some familial aggregation, pointing to a genetic predisposition. This study was set up to investigate the role of candidate genes in the susceptibility to lung cancer patients younger than 51 years at diagnosis.

Methods: 246 patients with a primary, histologically or cytologically confirmed neoplasm, recruited from 2000 to 2003 in major lung clinics across Germany, were matched to 223 unrelated healthy controls.

[Coincident manifestation of mesotheliomas of the tunica vaginalis and pleura. Case report and literature overview].

Malignant mesotheliomas are rare entities (0.1-0.2% of all malignant tumors) possibly localized at the pleura, peritoneum, pericardium, and tunica vaginalis.

18F-FDG PET for mediastinal staging of lung cancer: which SUV threshold makes sense?

Unlabelled: (18)F-FDG PET is the most accurate noninvasive modality for staging mediastinal lymph nodes in lung cancer. Besides using visual image interpretation, some institutions use standardized uptake value (SUV) measurements in lymph nodes. Mostly, an SUV of 2.

Clinical application of airway bypass with paclitaxel-eluting stents: early results.

Objective: To assess the safety and early clinical results of a multicenter evaluation of airway bypass with paclitaxel-eluting stents for selected patients with severe emphysema.

Methods: Airway bypass was performed with a fiberoptic bronchoscope in three steps: identification of a blood vessel-free location with a Doppler probe at the level of segmental bronchi, fenestration of the bronchial wall, and placement of a paclitaxel-eluting stent to expand and maintain the new passage between the airway and adjacent lung tissue. All adverse events were recorded, as well as 1- and 6-month pulmonary function tests and dyspnea index.

Progression of fibrosis in usual interstitial pneumonia: serial evaluation of the native lung after single lung transplantation.

Background: Idiopathic pulmonary fibrosis (IPF) is a progressive disease with a poor prognosis. Usual interstitial pneumonia (UIP) is the histopathological pattern identifying patients with the clinical entity of IPF. Despite aggressive immunosuppressive therapy the clinical course is usually dismal.
