AIM: To investigate the efficiency of guided bronchoscopy compared to blind techniques in the study of non-visible pulmonary lesions. MATERIALS AND METHODS: A one-year, retrospective, study was conducted comparing two populations: Biopsies were either performed conventionally (FB-B) with the help of static images and the second where biopsies were performed after guidance (FB-EBUS). A 20-MHz radial-type ultrasound probe was used to obtain images. Sampling techniques, like bronchial brushing and transbronchial biopsies, were conducted in both populations by two separate bronchoscopists...

BACKGROUND: Endobronchial ultrasound-guided fine-needle aspiration (EBUS-FNA) is a minimally invasive modality for diagnosing mediastinal lesions. When determining adequacy, EBUS-FNAs are evaluated for diagnostic material or sufficient lymphoid tissue. In this study, the authors evaluated their experience with EBUS-FNAs and correlated the findings with adequacy and histologic follow-up. METHODS: EBUS-FNAs were retrospectively reviewed over a 3-year period and correlated with the clinicopathologic findings, adequacy, and histologic follow-up...

BACKGROUND AND AIMS: Lung cancer is the most common cause of malignant pleural effusions (MPEs). For patients with lung cancer and MPE, median survival is only 3-4 months. The aim of this study was to evaluate lung cancer patients with MPE by clinical and laboratory findings on admission, and determine 2-year survival rate and prognostic factors. METHODS: Between 2008 and 2011, we examined 199 cases of non-small cell lung carcinoma with MPE. Demographic factors of patients, tumor characteristics, treatment delivered and laboratory parameters affecting prognosis were evaluated...

BACKGROUND AND AIMS: Determining clinical probability of pulmonary embolism (PE) with Wells scoring system is the first step towards diagnosis of PE. Definitive diagnosis of PE is confirmed by computed tomography pulmonary angiography (CTPA). METHODS: This was a prospective study on 80 patients referred to the Institute for Pulmonary Diseases of Vojvodina with suspected PE between April 2010 and August 2012. Clinical probability of PE was determined according to the Wells and modified Wells scoring system...

OBJECTIVE: To investigate the correlation between ultrasound (US) B-lines and high-resolution computed tomography (HRCT) findings in the assessment of pulmonary fibrosis (PF) in patients with connective tissue disorders (CTD). METHODS: Thirty-four patients with a diagnosis of CTD were included. Each patient underwent clinical examination, pulmonary function test (PFT), chest HRCT, and lung US by an experienced radiologist or rheumatologist. A second rheumatologist carried out US examinations to assess interobserver agreement...

RATIONALE: High-resolution computed tomography (HRCT) is an integral aspect of the evaluation of patients with suspected idiopathic pulmonary fibrosis (IPF). However, few studies have evaluated its use in a large cohort. OBJECTIVES: To describe HRCT features in patients with mild to moderate IPF, compare diagnostic evaluations by a radiology core (three thoracic radiologists) with those by study-site radiologists, correlate baseline clinical and physiologic variables with HRCT findings, and evaluate their association with mortality...

BACKGROUND: Identifying different phenotypes of chronic obstructive pulmonary disease (COPD) is important for both therapeutic options and clinical outcome of the disease. OBJECTIVE: To characterize the phenotypes of COPD according to high-resolution computed tomography (HRCT) findings; and to correlate HRCT scores obtained using the modified Bhalla scoring system with clinical and physiological indicators of systemic inflammation. METHODS: The present study included 80 consecutive patients with stable COPD...

RATIONALE: Lung clearance index (LCI) is a more sensitive measure of lung function than spirometry in cystic fibrosis (CF) and correlates well with abnormalities in high-resolution computed tomography (HRCT) scanning. We hypothesized LCI would be equally sensitive to lung disease in primary ciliary dyskinesia (PCD). OBJECTIVES: To test the relationships between LCI, spirometry, and HRCT in PCD and to compare them to the established relationships in CF. METHODS: Cross-sectional study of 127 patients with CF and 33 patients with PCD, all of whom had spirometry and LCI, of which a subset of 21 of each had HRCT performed...

BACKGROUND: The major responsibility of anaesthesiologist is to maintain adequate gas exchange in his patients in all circumstances and this require that patency of upper airway is constantly maintained. Problems with upper airway management are among the most frequent causes of anaesthetic mishaps. Using intubation difficulty scale (IDS) we made an attempt to objectively assess the predictors of difficult intubation. We assessed classical bedside tests such as modified Mallampati test, Thyromental distance test and also neck extension test...

OBJECTIVE: Postextubation distress after a successful spontaneous breathing trial is associated with increased morbidity and mortality. Predicting postextubation distress is therefore a major issue in critically ill patients. To assess whether lung derecruitment during spontaneous breathing trial assessed by lung ultrasound is predictive of postextubation distress. DESIGN AND SETTING: Prospective study in two multidisciplinary intensive care units within University Hospital...

BACKGROUND: Uncontrolled asthma during pregnancy is associated with maternal and perinatal hazards. A pharmacist-led intervention directed at improving maternal asthma control, involving multidisciplinary care, education, and regular monitoring to help reduce these risks, was developed and evaluated. METHODS: A randomized controlled trial was carried out in the antenatal clinics of two major Australian maternity hospitals. Sixty pregnant women < 20 weeks gestation who had used asthma medications in the previous year were recruited...

There is an increased focus on evaluating processes of care, particularly in the high acuity and cost environment of intensive care. Evaluation of neurocritical-specific care and evidence-based protocol implementation are needed to effectively determine optimal processes of care and effect on patient outcomes. General quality measures to evaluate intensive care unit (ICU) processes of care have been proposed; however, applicability of these measures in neurocritical care populations has not been established...

BACKGROUND: Malignant pleural effusion is a common problem in patients with solid tumours. It has a significant impact on quality of life, and, hence, there is a substantial need to investigate new agents to treat it. PATIENTS AND METHODS: This is a prospective randomised controlled study, including patients with symptomatic recurrent malignant pleural effusion of different primaries. Patients were randomised into two groups: the first group received five ampoules of mistletoe preparation with defined lectin content (Viscum Fraxini-2, ATOS Pharma) diluted in 10 cc glucose 5% solution...

Multicentric Castleman's disease (MCD) is an uncommon and often incurable lymphoproliferative disorder. There has been some recent evidence that rare cases of MCD manifest diffuse lung involvement, but the features in these cases are not well characterized. We report just such a biopsy-proven case of MCD with typical laboratory abnormalities including serum interleukin-6 elevation and characteristic high-resolution CT findings. Immunopathologically, the features of the lung tissue resembled those of lymphocytic interstitial pneumonia with predominant infiltration of B cells and plasma cells...

This report presents the case of a patient demonstrating multicentric Castleman's disease (MCD) with a lung lesion that was successfully treated with an anti-interleukin-6 receptor antibody, tocilizumab in combination with corticosteroid and tacrolimus. A 43-yr-old female with abnormal shadows on a chest X-ray was referred to the hospital for further examination. She was diagnosed as having MCD based on the characteristic pathology of inguinal lymph node, lung lesions, laboratory data, and undifferentiated arthritis...

PURPOSE: To assess the computed tomographic (CT) findings of intrathoracic involvement in multicentric Castleman disease. MATERIALS AND METHODS: The study comprised 12 patients with lymph node biopsy-proved Castleman disease and multicentric involvement. The patients were aged 23-58 years (mean age, 42.9 years; five men, seven women). Seven patients underwent open lung biopsy (n = 3) or transbronchial lung biopsy (n = 4), which demonstrated lymphocytic interstitial pneumonitis...

Limited information exists regarding the incidence and predictors of asthma and nasal allergy in adulthood. We determined the incidence rate of asthma and nasal allergy in adults and assessed the predictive value of skin prick tests (SPTs) and radioallergosorbent tests (RASTs) for these two outcomes. Two German centres involved in the European Community Respiratory Health Survey conducted a follow-up assessment in 2012 of the baseline participants (1185 adults aged 21-47 years assessed in 1990). The predictive value of SPTs and RASTs on new-onset asthma and nasal allergy was assessed by Cox regression and by calculating the positive or negative predictive value...

STUDY OBJECTIVE: To evaluate the effects of high analgesic doses of tramadol and meperidine on respiration, plasma catecholamine concentrations, and hemodynamic parameters. STUDY DESIGN: Randomized, double-blind, cross-over, controlled volunteer study. SETTING: Laboratory at a university hospital. SUBJECTS: 8 healthy male volunteers. INTERVENTIONS: Tramadol was given as a 150 mg bolus plus a succeeding 3-hour steady infusion of 250 mg (83...

(+/-)-Tramadol is a synthetic 4-phenyl-piperidine analogue of codeine. It is a central analgesic with a low affinity for opioid receptors. Its selectivity for mu receptors has recently been demonstrated, and the M1 metabolite of tramadol, produced by liver O-demethylation, shows a higher affinity for opioid receptors than the parent drug. The rate of production of this M1 derivative (O-demethyl tramadol), is influenced by a polymorphic isoenzyme of the debrisoquine-type, cytochrome P450 2D6 (CYP2D6). Nevertheless, this affinity for mu receptors of the CNS remains low, being 6000 times lower than that of morphine...
