Dear all,
Me and co-authors are pleased to announce the publication of our paper Tension 
pneumothorax in small odontocetes, in the journal Diseases of Aquatic 
Organisms. The publication is open access, and is available at
https://www.int-res.com/articles/dao_oa/d155p043.pdf
Video files of CT scan of two of the cases are available as supplementary 
materials of the publication, but for those of you interested, we will be 
pleased to share DICOM files on demand. See below the abstract of the 
publication.

ABSTRACT: Pneumothorax, the accumulation of air in the pleural cavity, occurs 
when air enters the pleural space by the pleuro-cutaneous, pleuro-pulmonary, or 
pleuro-oesophageal-mediastinal route. Tension pneumothorax is an infrequent and 
severe form of pneumothorax where a positive pressure in the pleural space is 
built up during at least part of the respiratory cycle, with compression of 
both lungs and mediastinal vessels, and, if unilateral, with midline deviation 
towards the unaffected hemithorax. We describe 9 cases of tension pneumothorax 
in 3 species of small cetaceans (striped dolphin Stenella coeruleoalba, common 
dolphin Delphinus delphis, and common bottlenose dolphin Tursiops truncatus) 
from the western Mediterranean coast of Spain, and one case from a 
dolphinarium. Computed tomography (CT) imaging performed in 2 carcasses before 
necropsy showed lung compression, midline deviation, and pressure on the 
diaphragm, which was caudally displaced. Tension pneumothorax was recognized at 
necropsy by the presence of pressurized air in one of the hemithoraces. Seven 
of the pneumothorax cases were spontaneous (2 primary and 5 secondary to 
previous lung pathology). In the other 2 dolphins, the pneumothorax was 
traumatic, due to oesophageal-pleural perforation or rib fractures. We 
hypothesize that pneumothorax in dolphins is predominantly tensional because of 
their specific anatomical and physiological adaptations to marine life and the 
obligate exposure to extreme pressure changes as diving mammals.
