Aim: We prospectively assessed survival, QoL and dyspnea (using validated EORTC questionnaire) in patients with mCAO 1 day before interventional bronchoscopy, 1 week after and every following month, in comparison to patients who declined this approach. Material/Patients/Methods: 36 patients underwent extensive interventional bronchoscopic management as indicated, whereas 12 declined. All patients received full chemotherapy and radiotherapy as indicated. Patients of the 2 groups were matched for age, comorbidities, type of malignancy and level of obstruction. Follow up time was 8.0±8.7 (range 1-38) months. Results: Mean survival for intervention and control group was 10±9 and 4±3 months respectively (p=0.04). QoL improved significantly in intervention group patients up to the 6 th month (p<0.05) not deteriorating for those surviving up to 12 months. Dyspnea decreased in patients of the intervention group 1 month post procedure remaining reduced for survivors over the 12th month. Patients of the control group had worse QoL and dyspnea in all time points. Conclusions: Interventional management of patients with mCAO, may achieve prolonged survival with sustained significant improvement of QoL and dyspnea.

Here we report a case of acute transverse myelitis in a previously healthy 26-year-old male, during the course of a lower respiratory infection. The diagnosis was based on magnetic resonance imaging findings of the spinal cord and on the quantitative determination of IgM and IgG antibodies against M. pneumoniae in the serum and a positive nested PCR test in the sputum. Diagnostic workout did not reveal any other cause of the neurological symptoms. The patient was treated successfully with intravenous azithomycin and doxycycline. His recovery was progressive and he was discharged without any neurologic sequelae.

Research paper thumbnail of Long-Term Management of Extensive Tracheal Stenosis due to Formic Acid Chemical Burn

Respiration, 2005

Twenty years after the initial injury, she presented with dyspnea and stridor due to severe tracheal stenosis. Several interventional bronchoscopic manipulations were initiated: incision of the stenotic lesion with Nd:YAG laser and dilatation with a valvuloplasty balloon which enabled silicone stent placement which was subsequently kept in place for 3 years. Complications during the 4th year after stenting led to the successful replacement of this stent by two autoexpandable metallic stents covering the total length of the trachea from the subglottic area to the carina. In post-burn inhalation injuries, a complex inflammatory process may be active for many years after the initial insult. These injuries respond to prolonged tracheal stenting and a conservative approach is recommended.

This also involves responsibility for treating related complications. Training in interventional pulmonology is warranted.

Research paper thumbnail of Fluorescein-enhanced Autofluorescence Thoracoscopy in Patients with Primary Spontaneous Pneumothorax and Normal Subjects

In one patient with PSP, fluorescein-enhanced autofluorescence thoracoscopy (FEAT) has shown areas of parenchymal abnormality unnoticed during white light thoracoscopy (WLT). Objectives: To prospectively perform and compare WLT and FEAT in patients with spontaneous pneumothorax and in normal subjects. Methods: One-time FEAT and WLT inspection with systematic mapping of semiquantified lesions in 12 consecutive patients with PSP was compared with one-time FEAT and WLT during sequential bilateral thoracoscopy in 17 control subjects. Results: WLT abnormalities (anthracosis, cobblestone malformation, and blebs/bullae) were more prevalent in PSP. FEAT, however, showed high-grade lesions in PSP only, which often were present at areas that were normal, or that only showed anthracosis at WLT. When blebs/bullae were present, bleb-associated FEAT abnormalities were only present in two. Actual fluorescein leakage was seen in two patients with PSP. Conclusions: Lungs in patients with PSP show significantly more abnormalities at WLT when compared with normal subjects. Highgrade FEAT lesions were exclusively present in PSP, and predominantly at lung zones that appeared normal at white light inspection. These findings suggest that significant parenchymal abnormalities are not limited to lesions visible during WLT, such as blebs and bullae.

Research paper thumbnail of Lobectomy due to Pulmonary Vein Occlusion after Radiofrequency Ablation for Atrial Fibrillation

Pulmonary vein stenosis/occlusion is one of its rare complications. Herein, the case of a 50-year-old man with hemoptysis and migratory pulmonary infiltrations after transcatheter radiofrequency ablation for atrial fibrillation is presented. Initially, pneumonia, interstitial pulmonary disease, or lung cancer was suspected, but wedge resection revealed hemorrhagic infiltrations. Chest computed tomography pulmonary angiography detected no left superior pulmonary vein due to its total occlusion, and left upper lobectomy was performed. Post-ablation pulmonary vein occlusion must be strongly suspected in cases of migratory pulmonary infiltrations and/or hemoptysis.

Research paper thumbnail of Greek Guidelines for the Management of COPD, a Proposal of a Holistic Approach Based on the needs of the Greek Community

The pathology and pathophysiology of this disease continue to be studied, with new pharmacological and invasive therapies emerging. In this consensus paper, the Working Group of the Hellenic Thoracic Society aimed to consolidate the up-to-date information and new advances in the treatment of COPD. Local and international data on its prevalence are presented, with revised strategies on the diagnostic approach and the evaluation of risk assessment and disease severity classification. Emphasis is placed on the management and therapy of patients with COPD, covering both common principles, specialized modalities, and algorithms to distinguish between home care and the need for hospitalization. Although pharmacological treatment is commonly recognized in COPD, an integrati...
