OBJECTIVE:This prospective study was conducted to evaluate the value of sonographic B-lines (previously called “comet tail artifacts”), which are long, vertical, well-defined, hyperechoic, dynamic lines originating from the pleural line in assessment of interstitial lung diseases (ILD) and compare them with the findings of chest high-resolution computed tomography (HRCT) and pulmonary function tests (PFTs).MATERIALS AND METHODS:Sixty-one patients with ILD underwent transthoracic lung ultrasound for assessment of the presence of B-lines and the distance between them. These findings were compared with that of chest HRCT (ground glass, reticular, nodular or honey combing) and PFT as forced vital capacity (FVC), total lung capacity (TLC), diffusion capacity for carbon monoxide (DLCO) and partial arterial oxygen pressure (PaO2).RESULTS:All patients had diffuse bilateral B-lines. The distance between each of the two adjacent B lines correlated with the severity of the disease on chest HRCT where B3 (the distance was 3 mm) correlated with ground glass opacity and B7 (the distance was 7 mm) correlated with extensive fibrosis and honey combing. Also, the distance between B-lines inversely correlated with FVC (r = −0.848, P < 0.001), TLC (r = −0.664, P < 0.001), DLCO (r = −0.817, P < 0.001) and PaO2 (r = −0.902, P < 0.001).CONCLUSION:B-lines that are lung Ultrasound signs seem to be useful in the assessment of ILD.

Objectives: Adherence to therapy is very important and many factors could be responsible for this issue. Suboptimal adherence to asthma therapy is a major contributor to poor asthma outcomes. Our aim is to find out the most important factor responsible for adherence to therapy in bronchial asthma patients.Subjects and methods: The study included 143 patients with persistent bronchial asthma. Factors that may affect adherence to therapy were studied. These factors included age, sex, residence, level of education, proper asthma education and whether inhaled corticosteroid (ICS) was taken alone, with long acting b2 agonist (LABA) in separate devices or with LABA in a combined form. Adherence to ICS was determined according to Medication Rating Scale.Results: We found that 55.3% of patients that received asthma education were adherent to ICS while only 21% of patients that did not receive asthma education were adherent to ICS therapy. The difference was statistically highly significant (p = 0.003). Other factors do not significantly affect adherence to ICS. Patients that used combined ICS with LABA in the same device were significantly more adherent to therapy (60.25%) than patients that used the same combination in 2 separate devices (34.5%). All patients with well controlled asthma were adherent to ICS, while 47.5% of uncontrolled patients was adherent. Comparison between level of control and adherence to ICS was highly significant (p = 0.003).Conclusion: This study showed how different factors may modulate adherence to asthma treatment and confirmed the importance of patient education in increasing adherence to asthma therapy.

TUS is a reliable diagnostic bedside test for PTE in critically ill and immobile patients. Adding color Doppler to gray-scale TUS increases the specificity and accuracy and consequently the confidence in the diagnosis of peripheral pulmonary infarctions and differentiates them from other pulmonary lesions that allow initiation of anticoagulants.
