    How successful is pleural sound sign in the identification of pneumothorax?
    (Kare Publ, 2019) Calik, Saniye Goknil; Calik, Mustafa; Girisgin, Sadik; Karaoglan, Osman; Dundar, Zerrin Defne; Ergin, Mehmet
    OBJECTIVE: In the present study, in thorax ultrasonography (USG) Doppler images obtained from cases with occult pneumothorax, we investigated the status of pulsatile pleural sounds over the pleural line and called these as the pleural sound sign (PSS). The purpose of the present study was to identify the efficacy of the proposed PSS in diagnosing pneumothorax and to compare it with the other USG findings including the sliding lung sign (SLS) and seashore sign (SSS). METHODS: The present study included 66 consecutive patients who were referred to the emergency unit with a blunt trauma from October 2009 to January 2010 at a tertiary university hospital. RESULTS: Of the 66 patients, 34 were in the patient group, and 32 were in the control group. Males accounted for 66.7% (n=44) of the study population. In predicting pneumothorax, the areas under receiver operating characteristic (ROC) curves of PSSmax and PSSdifference were 0.989 and 0.990, respectively. While the sensitivity of the SLS was 88% and the sensitivity of the SSS was 56%, the specificities of the SLS and SSS were 100%. Based on our findings, accuracy ranking was as follows: PSSmax = PSSdifference > SLS > SSS. CONCLUSION: New applications of thorax USG are rapidly growing. Our findings have to be confirmed in a large patient series. PSS is not a novel method, but it enhanced the importance of USG in the diagnosis of pneumothorax. We can stipulate that it can replace thorax computed tomography imaging particularly for the diagnosis of occult pneumothoraxes.

    A new development in emergency department ultrasonography: Pleural Sliding Sound (PSS)
    (Professional Medical Publications, 2012) Ergin, Mehmet; Girisgin, Abdullah Sadik; Karaoglan, Osman; Calik, Goknil; Kocak, Sedat; Cander, Basar
    Ultrasonography (USG) is widely used in emergency departments to assist in the diagnosis and treatment of patients. An increasing number of studies in the unconventional use of USG in thorax and lung examination have been conducted in recent years. Sliding lung sound (SLS) has been researched extensively during the last decade was accepted as a radiologic sign in 2008. However, determining SLS requires a certain degree of clinical experience since it is a subjective indicator. We have discovered the pleural sliding sign (PSS), which is as valuable as the SLS, but more objective sign. PSS is present at any time when SLS is present; furthermore, it can be used as a diagnostic sign even when the SLS is doubtful. In this study, we present our views on PSS and in particular wish to share this information with clinicians who are interested in performing emergency USG. We also aim to stimulate further research on this subject.
