Abstract

Spontaneous pneumomediastinum is an uncommon event, the clinical picture of which includes retrosternal chest pain, subcutaneous emphysema, dyspnea, and dysphonia. The pathophysiological mechanism involved is the emergence of a pressure gradient between the alveoli and surrounding structures, causing alveolar rupture with subsequent dissection of the peribronchovascular sheath and infiltration of the mediastinum and subcutaneous tissue with air. Known triggers include acute exacerbations of asthma and situations that require the Valsalva maneuver. We described and documented with HRCT scans the occurrence of pneumomediastinum after a patient with bleomycin-induced interstitial lung disease underwent pulmonary function testing. Although uncommon, the association between pulmonary function testing and air leak syndromes has been increasingly reported in the literature, and lung diseases, such as interstitial lung diseases, include structural changes that facilitate the occurrence of this complication.

Attention Score in Context

This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 07 December 2013.
All research outputs
#3,894,641
of 4,655,094 outputs
Outputs from Jornal Brasileiro de Pneumologia
#1
of 1 outputs
Outputs of similar age
#100,151
of 123,880 outputs
Outputs of similar age from Jornal Brasileiro de Pneumologia
#1
of 1 outputs
Altmetric has tracked 4,655,094 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1 research outputs from this source. They receive a mean Attention Score of 0.0. This one scored the same or higher as 0 of them.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 123,880 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
