et al.

Abstract: Objectives: The objective was to determine if use of ultrasound (US) by emergency physicians (EPs) to localize spinal landmarks improves the performance of lumbar puncture (LP).Methods: This was a prospective, randomized, controlled study conducted in a county teaching hospital. Subjects, adults 18 years of age or older who were to receive LPs for routine clinical care in the emergency department (ED), were randomized either to undergo US localization of the puncture site or to have the puncture site determine… Show more

“…Our results are in line with the results detailed in the study by Peterson et al 2 on the utility of routine ultrasonography in performing lumbar punctures in an unselected population 2. Similar results were duplicated in a randomised controlled trial with 158 subjects 10.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…This is consistent with a growing body of the literature that suggests a negligible to small effect of POCUS on the success rate of LP. [13][14][15][16] Our study also corroborates similar findings by Peterson et al [15] who found that, in a sample of 100 patients randomized to ultrasound and palpation only groups, there was no benefit of US in reducing procedural success, needle insertions, and procedure time. It is worth noting that Peterson et al [15] also did not fi nd a benefi t of US in patients with diffi cult landmarks.…”

There was a difference, however, in how Peterson et al [15] operationalized difficult landmarks compared to how we operationalized it.…”

“…The high success rate of US-assisted LP in the current study is similar to or better than reported in most other studies 3 . Nonetheless, lower success rates of US-assisted LP have been reported in some studies 4 , 5 , 8 . This finding suggests that US is operator-dependent, and the success of US-assisted LP in the current study might be partially explained by the familiarity of the examiner with US imaging in the neuromuscular clinic setting.…”
