Prolonged air leak is quite a common pulmonary complication after pulmonary lobectomy and can be treated conservatively. This complication significantly prolongs the length of hospitalization (P<0.01). We also conclude that COPD increases the risk of an air leak persisting for longer than 7 days.

Background: Clinically significant benign stenoses of the large airways develop in about 1% of patients after intubation. The management of benign stenoses is not unified around the world, nor are there any accepted methods for their screening. Objectives: The purpose of this study is to describe and compare results of interventional bronchoscopy and surgical therapy of benign stenoses as well as to propose an algorithm for the management of this airways disorder. Methods: Prospective study on 80 consecutive patients with benign stenoses of the large airways admitted to the Pulmonary Department of the University Hospital of Prague-Motol. Results: Sixty-two patients developed stenoses after endotracheal intubation or tracheostomy, in 18 patients the stenosis was caused by other diseases or pathological situations. Thirty-eight patients were sent for surgical resection of the stenotic part of the airways. 2 surgically treated patients developed recurrence of the stenosis and had to be reoperated on. Narrowing of the trachea at the site of end-to-end anastomosis developed in 6 other patients and was cured by interventional bronchoscopy. The remaining 42 patients were treated by interventional bronchoscopy (Nd-YAG laser, electrocautery, stent) which was curative in 35 patients. Sixty-five patients were alive at the time of evaluation, 15 patients died. Five of them died between 3 and 14 (median 4) months after surgery from a disease other than airway stenosis. Ten nonresected patients also died, with 1 exception, due to a disease other than airway stenosis; the median survival was 9 months. Conclusions: We recommend to assess the patient for surgery after the initial diagnosis and therapeutic bronchoscopy with dilatation of the stenosis. If the patient is not a suitable candidate for resection, interventional bronchoscopy is an appropriate alternative for the management of benign stenoses of the large airways.

Abstract:Objectives: The aim of our study was to evaluate impact of CYP2D6 and MDR1 polymorphisms on the analgesic effi cacy of tramadol in patients after a knee arthroscopy. Background : Pharmacokinetics of tramadol and its metabolites is stereoselective and displays high interindividual variability correlating with polymorphic CYP2D6 in the population. Available data provide controversial results regarding the analgesic effi cacy of tramadol in subjects with different CYP2D6 genotypes. Methods: Pain intensity was assessed using visual analogue scale at 2 and 24 hours after the knee arthroscopy in 156 patients. Polymorphisms CYP2D6*3,*4,*5,*6, and gene duplication and C3435T in MDR1 gene were analyzed by PCR -RFLP. Results: Mean VAS 2h value in the whole study group was 44.0 ± 16.5 mm. Mean pain difference, was lowest in the UM group and highest in the PM group. The pain difference varied signifi cantly among the CYP2D6 subgroups (F = 4.29; p = 0.006) with signifi cant differences between homEM vs hetEM, homEM vs PM, and UM vs PM subgroups. There were no signifi cant differences among MDR1 subgroups with regards of pain difference. Mean tramadol consumption was 2.47 ± 1.17 mg/kg during the 24 h period. There were no signifi cant differences in the drug consumption, reporting of adverse reactions, need for rescue analgesic medication or verbal description of pain among the CYP2D6 or MDR1 genotype subgroups. Conclusion: CYP2D6 plays a signifi cant role in tramadol analgesic effi cacy. The non-opioid analgesia in PMs was associated with better subjective pain relief in patients after a knee arthroscopy (Tab. 3, Ref. 18). Full Text in PDF www.elis.sk.

Postlobectomy atelectasis is an important postoperative complication. Patients with COPD and those undergoing RUL are at higher risk of this complication. Although often isolated, PLA is associated with longer hospital stay.

The increase in the detection rate for premalignant changes of bronchial epithelium was studied in 56 symptom-free volunteers from the risk group of Czech uranium miners (mean age 50.69 years, mean WLM 21.06 (1 Working Level Month is equal to the absorption of latent energy of 2.08 10 -s J/m 3 in one month, i.e. 170 working hours)) by the additional employment of the System of Autofluorescence Endoscopy (SAFE-1000 Pentax) to conventional white-light bronchoscopy, comparing results with those of bronchial biopsy histopathology examination. Histopathology using hematoxylin and eosin staining confirmed intraepithelial neoplasias in 15 areas in 10 persons. White-light bronchoscopy sensitivity was 21.05%, and specificity 93.7% which an autofluorescence bronchoscopy sensitivity was 78.95%, and specificity 81.89%.
