ABSTRACT
INTRODUCTION: Standard ultrasound gives the operator a dynamic morphology of the investigated anatomy, whereas ultrasound elastography (USE) provides quantitative and qualitative information about the elastic properties of the tissues. OBJECTIVES: We designed a single-arm prospective study in order to investigate the feasibility of USE in the diagnosis of pneumothorax if a lung point sign is present. METHODS: Thirty patients were enrolled in this protocol, from January 2017 to December 2018 at the Pneumology Department of the Azienda Socio-Sanitaria Territoriale Spedali Civili (Brescia, Italy). Patients who were suspected of having pneumothorax were previously evaluated with standard ultrasonography, and then, in the presence of lung point, we performed strain elastography. All patients were evaluated in supine and sitting positions with a linear probe (7.5 MHz). USE enhanced the air-tissue interface dividing the normal parenchyma from the air column of pneumothorax with a sharp line. We called this sign "elasto-lung point." RESULTS AND CONCLUSION: The "elasto-lung point" was able to confirm the diagnosis of pneumothorax in every investigated patient. USE is a simple, reproducible and inexpensive technique that can contribute to the diagnosis of pneumothorax, such as the classic "stratosphere" or "Bar Code" sign in M-mode. No false negative cases were observed.
ABSTRACT
INTRODUCTION: Smoking is the major risk factor for cancer and several respiratory diseases. Quitting smoking at any point of life may increase the effectiveness of treatments and improve prognosis of patients with any pulmonary disease, including lung cancer. However, few institutions in Europe offer to patients adequate counseling for smoking cessation. OBJECTIVES: Aim of this study was to investigate the level of counseling for smoking cessation offered by healthcare professionals to patients and their appreciation towards the intervention itself. METHODS: Between January 2013 and February 2016, 490 patients, diagnosed with a respiratory diseases, were prospectively evaluated with an anonymous survey developed by WALCE (Women Against Lung Cancer in Europe). RESULTS: The majority of patients enrolled (76%) declared to have stopped smoking after the diagnosis of a respiratory disease, 17% to smoke less, 7% to continue smoking. Patients who reported to have never received any counseling for smoking cessation were 38%. Almost 73% of the other patients reported a positive judgment about the quality of healthcare's intervention. Despite these favorable considerations, 83% of patients have disclosed they simply quit smoking overnight without help, 5% have used electronic cigarettes, 5% nicotine replacement treatments, 4% dedicated books, 3% have attended a referral clinic. CONCLUSIONS: Considering all the smoking-related side effects, greater efforts should be made in order to better support patients in smoking cessation. Smoking should be considered as a real physical disorder and similar surveys should be encouraged with the aim to fight the 'stigma' of smoking that still exists among patients.
