Abstract

To characterize clinically all of the patients with spontaneous pneumomediastinum (SPM) admitted to an adult pulmonology ward in Lisbon, Portugal. This was a retrospective descriptive study of all adult patients (≥ 18 years of age) diagnosed with SPM between January of 2004 and September of 2015. At least one predisposing factor was identified in most (88.9%) of the 18 patients who presented with SPM during the study period. With regard to precipitating factors, bouts of cough were present in 50.0% of the patients. Other precipitating factors included a sudden increase in tobacco consumption, inhaled drug use, occupational inhalation of varnish fumes, intense exercise, and vomiting. The most common complaints were dyspnea (in 83.3%) and chest pain (in 77.8%). Other complaints included cough, neck pain, dysphagia, and odynophagia. Subcutaneous emphysema was found in most of the patients. The diagnosis of SPM was based on chest X-ray findings in 61.1% of the patients. Although SPM is a rare condition, it should be considered in the differential diagnosis of chest pain and dyspnea. It can develop without a triggering event or conclusive findings on a chest X-ray, which is usually sufficient for diagnosis. Caracterizar clinicamente todos os pacientes com pneumomediastino espontâneo (PME) admitidos em uma enfermaria de pneumologia para adultos em Lisboa, Portugal. Estudo descritivo retrospectivo no qual foram analisados todos os pacientes adultos (≥ 18 anos de idade) com diagnóstico de PME entre janeiro de 2004 e setembro de 2015. Pelo menos um fator predisponente foi identificado na maioria (isto é, em 88,9%) dos 18 pacientes que apresentaram PME durante o período de estudo. No tocante a fatores precipitantes, crises de tosse ocorreram em 50,0% dos pacientes. Outros fatores precipitantes foram um aumento repentino do consumo de tabaco, uso de drogas inalatórias, inalação ocupacional de vapores de vernizes, exercício intenso e vômitos. As queixas mais comuns foram dispneia (em 83,3%) e dor torácica (em 77,8%). Outras queixas foram tosse, cervicalgia, disfagia e odinofagia. Constatou-se a presença de enfisema subcutâneo na maioria dos pacientes. O diagnóstico de PME baseou-se na radiografia de tórax em 61,1% dos pacientes. Embora seja uma doença rara, o PME deve ser levado em conta no diagnóstico diferencial de dor torácica e dispneia. O PME pode surgir sem um evento desencadeante e sem achados conclusivos na radiografia de tórax, que é geralmente suficiente para o diagnóstico.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 5. 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 26 July 2017.
All research outputs
#6,784,032
of 25,461,852 outputs
Outputs from Jornal de Pneumologia
#105
of 719 outputs
Outputs of similar age
#101,057
of 324,174 outputs
Outputs of similar age from Jornal de Pneumologia
#1
of 1 outputs
Altmetric has tracked 25,461,852 research outputs across all sources so far. This one has received more attention than most of these and is in the 72nd percentile.
So far Altmetric has tracked 719 research outputs from this source. They receive a mean Attention Score of 3.7. This one has done well, scoring higher than 85% of its peers.
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 324,174 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
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
