BACKGROUND EBUS guided trans-bronchial biopsy became routine in diagnosis of peripheral pulmonary lesions (PPL). Suction catheter-biopsy is a technique for obtaining a tissue sample from peripheral lung parenchyma. Aim of this study was to evaluate diagnostic efficiency, feasibility and safety of EBUS guided suction catheter-biopsy (SCB) in comparison to trans-bronchial biopsy (TBB) in diagnosi...
Background: Identifying the sources of variation in QTc measurements is important for preventing arrhythmias during and after hemodialysis. The present study was designed to determine the correlation between the type of hemodialysis buffer and the changes in QTc interval in patients on chronic hemodialysis. Methods: Fifty-nine patients on chronic hemodialysis who referred in winter 2007 to hemo...
We report a measurement of the large optical transmission matrix (TM) of a complex turbid medium. The TM is acquired using polarization-sensitive, full-field interferometric microscopy equipped with a rotating galvanometer mirror. It is represented with respect to input and output bases of optical modes, which correspond to plane wave components of the respective illumination and transmitted wa...
Changes in plasma volume in vivo cause rapid changes in extracellular pH by altering the plasma bicarbonate concentration at a constant Pco(2) (Garella S, Chang BS, and Kahn SI. Kidney Int 8: 279, 1975). Few studies have examined the possibility that changes in cell volume produce comparable changes in intracellular pH (pH(i)). In the present study, alveolar macrophages were exposed to hyperosm...
Eight single lung transplant recipients with emphysema, aged 40-58 yrs, have been followed up for 90 patient months. Starting 2-4 weeks postoperatively, they recorded their forced vital capacity (FVC), and forced expiratory volume in one second (FEV1), at a fixed time every morning using a Micro Spirometer. They were instructed to contact the hospital if the FVC or FEV1 displayed a persistent (...
There are few reports on the p53 status of small cell lung cancer (SCLC) and advanced non-SCLC (NSCLC) because surgically resected specimens are generally not available. Therefore, we evaluated p53 immunostaining in 175 transbronchial biopsy (TBB) specimens obtained from patients with all stages of lung cancer and retrospectively evaluated the relationship between p53 status and clinical parame...
OBJECTIVE To review and compare the 'metabolic' component of an acid-base abnormality by assessing the arterial blood bicarbonate and the 'strong ion difference'. DATA SOURCES A review of published peer-review articles and studies reported from 1983 to 1999 and identified through a MEDLINE search on 'strong ion difference'. SUMMARY OF REVIEW The Henderson-Hasselbalch equation describes the ...
In this paper, we present an approach to reconstruct 3-D human motion from multi-cameras and track human skeleton using the reconstructed human 3-D point (voxel) cloud. We use an improved and more robust algorithm, probabilistic shape from silhouette to reconstruct human voxel. In addition, the annealed particle filter is applied for tracking, where the measurement is computed using the reproje...
Pulmonary Langerhans cell histiocytosis (PLCH) is a rare interstitial lung disease characterized by the accumulation of histiocytes within the airspaces or parenchyma of the lung. It almost always occurs in smokers between the ages of 20 and 40. Bronchoscopic interventions, such as transbronchial biopsy (TBB) and bronchoalveolar lavage (BAL), should be performed before other more invasive proce...
