3%), and one required a chest drain.

Symptoms are a common feature of thoracentesis even when performed by experienced operators in ideal settings. Complications, however, are rare when the procedure is performed with bedside ultrasound and attention is paid to patient-reported symptoms and volume drained. Specialist pleural clinics provide a good model for a standardized approach to safe performance of this common procedure.

The single-breath diffusing capacity of the lungs (DLCOSB) test measures the extent to which carbon monoxide (CO) passes from the lung air sacs into the blood. The accessible alveolar volume (VASB) is measured by inert gas during a 10-second period. The single-breath transfer coefficient of the lung for carbon monoxide (KCOSB) is the DLCOSBdivided by VASB. Cystic fibrosis (CF) disease comprises progressive airway obstruction with bronchiectasis and parenchyma fibrosis. Yet, the KCOSBappears insignificant in the assessment of pulmonary function in CF.

To challenge the precision of normal KCOSBin CF.

The authors collected pulmonary function tests (PFT) data from 74 confirmed CF patients (mean age 26 ± 10 years) with various levels of pulmonary disease severity. Tests included spirometry, DLCOBP, and body plethysmography (BP). Anatomical dead space was calculated by deducting anatomical dead space from total lung capacity TLC(BP) to establish alveolar volume (VABP) and to determine KCOBP. We also included individual data of arterial pCO2 blood-gas level.

KCOSBvalues were normal or higher in most patients, regardless of patient FEV1 value (R2 = 0.2204; P < 0.02). In contrast, the measurements of KCOBPwere low corresponding with low FEV1 values, and negatively correlated with the elevation of trapped air and pCO2 levels (R2 = 0.1383; P = 0.0133, P > 0.05, respectively).

The 10- second perfusion time of the inert gas during DLCOSBrepresent the communicative alveolar volume in CF patients with advanced pulmonary disease. The findings justify the use of DLCOSBwith the deterioration of FEV1 and elevation of pCO2 levels.

Lung percutaneous needle biopsy (PNB) is routinely used to diagnose lung cancer. The most prevalent complications of PNB are pneumothorax and bleeding. read more Differences in characteristics of medical procedures between rural and urban hospitals are well known.

To compare characteristics of patients and lesions between two hospitals and to evaluate whether lung PNB complications differ in rural vs. urban settings.

The authors examined case records of 561 patients who underwent lung biopsy at two different medical centers in Israel Tel Aviv Sourasky Medical Center (urban) and Barzilai Medical Center (rural). To evaluate the complication rates, the authors analyzed findings from chest X-ray performed 2 hours after biopsy and computed tomography (CT) images at the site of biopsy.

The study comprised 180 patients who underwent lung biopsy at Barzilai and 454 at Sourasky. The rate of pneumothorax did not differ between centers (12% at Barzilai and 19% at Sourasky, P = 0.08). Distance from pleura was positively correlated to pneumothorax occurrence in both centers; however, neither lesion size nor lesion locus was found to be a risk factor for pneumothorax. Mild bleeding at the biopsy site occurred equally at Barzilai and Sourasky (32% vs. 36%, P = 0.3, respectively). Furthermore, immediate CT post-biopsy at Barzilai showed 95% negative predictive value, showing that a CT scan performed immediately after lung biopsy cannot replace the routine follow-up chest X-ray in predicting iatrogenic pneumothorax.

CT-guided percutaneous lung biopsies are comparable between rural and urban hospitals regarding procedure characteristics and complication rates.

Chronic obstructive pulmonary disease(COPD) is a common and debilitating condition, often accompanied by other co-morbidities. The Hadassah Medical Center'smulti-disciplinary approach in treating COPD patients in a one-stop shopfor COPD patients is the first of its kind in Israel. It includes pulmonary physicians, a nurse coordinator, dietitian, psychotherapist, physiotherapist, and a smoking cessation program.

To characterize efficacy of such a program in COPD patients.

Demographic and clinical data from patients referred to the Hadassah COPD center, including co-morbidities, baseline symptoms (using the CAT questioner), spirometry results, 6-minute walking distance (6MWD) test and current treatment were collected and compared to the same data after 6-12 months of treatment.

Some 154 patients were evaluated; mean age 64 years; 67% male; 53% current smokers. Only 74% received chronic treatment for COPD. Average body mass index was 28, CAT score 21.3, and mean FEV1 was 1.38 liters (53% of predicted).The mean exacerbation rate during the year prior to referral was 1.72 with a 1.07 annual admission rate. Following treatment, a small increase was noted in FEV1 to 1.47 liters, 54.4% of predicted; improvement in CAT scores to 16.5 with improvement seen in 70% of patients, and a 42 meter increase in the 6MWD (from 344 to 386 meters) with some improvement of effort capacity in 77% of patients. The rate of smokers decreased to 21%, and 97% of patients received medical treatment for COPD.

Multidisciplinary approach is feasible and efficacious in patients with COPD.
