Special Issue Information

Dear Colleagues,

Diseases of the upper and lower respiratory systems of adult horses, whether or not broadly contagious, are frequent and of medical importance for the following reasons: their potential severity, nosographic dismemberment to understand their etiology and pathogenesis, and the necessary development of reliable diagnostic means based on consensual procedures to assess their pathophysiology.

Regarding guttural pouches

With the necessary knowledge to explore means beyond endoscopy, we can go beyond endoscopic examination, it is essential to continue to explore: (i) developmental conditions of mycosis and its evolution after various surgical treatments aimed at preventing catastrophic bleeding; (ii) the effective treatments according to precise and evaluated procedures of the empyemas; (iii) understanding the eardrum and its best surgical management.

Regarding bronchopulmonary diseases

The clinician needs the perspective of the anatomical pathologist on the various non-infectious inflammatory conditions and the differential damage to the bronchial, bronchiolar and alveolar territory. They can then examine the diagnostic methods by adapting reliable and scientifically evaluated examination techniques to determine the resulting condition.

Understanding the pathogenesis of bronchopulmonary infections could make it possible to propose appropriate sampling techniques for the examination of infection. As in other species, the pathogenetic, clinical, and therapeutic differences of pleuro-pneumonia, infectious pneumonia (pneumonia), and non-infectious inflammatory pneumonia (pneumonitis) deserve a factual approach within the literatures.

A reflection should be carried out on the new denominations for non-infectious inflammations of the airways, whether allergic or not and accompanied by obstructive ventilatory disorder or not, in the hope that they have a real paradigmatic justification. Beyond that, an evidence-based medicine approach appears essential for better management of these conditions in terms of (i) diagnostic methods, (ii) the different types according to the categories of horses, (iii) the pathogenesis of these conditions, (iv) the development of reproducible protocols for diagnostic methods and (v) the different therapeutic protocols according to the phenotyping of these conditions by also reasoning on the quality of life of the affected and treated horses.

From all these data, retrospective multicenter studies on feedback from clinical practice, one or more anatomopathological observatories of these lung diseases, and prospective studies on the management protocols for these different diseases could be created.

For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Veterinary Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs).

The temporary ligation of the common carotid artery is performed as an emergency aid in cases of guttural pouch mycosis. Its usefulness is put into perspective after an anatomical summary of arterial vascularization involving a guttural pouch. It helps to better understand the need for the cranial (cerebral) and caudal (cardiac) occlusion of an arterial rupture by embolization in order to achieve maximum success in preventing and treating an hemorrhage. Topical oxygen therapy used alone or in a multimodal approach with embolization surgery is performed to promote healing of the inflammatory and mycotic lesions observed when an individual is affected. In conclusion, this three-step therapeutic approach should enable the equine practitioner to better orient their decision tree when faced with this condition which, while rare, can be potentially fatal if poorly treated.

Guttural pouch endoscopy allows for both the visualization and treatment of many clinical problems in the equine retropharyngeal region. This area is extremely complex, and its description remains a real challenge for veterinary anatomists and practitioners. Six clinically normal equine cadavers were employed. Conventional dissections of guttural pouches without penetrating the guttural pouch membrane were first performed, and each adjacent structure was identified. Then, a guttural pouch endoscopic exam of the dissected heads was performed in order to correctly map each visible underlying anatomic structure identified in the previous dissection. This allowed us to: 1—identify each structure visible on endoscopic examination of the guttural pouch; 2—create a representative map of all the structures accurately identified via endoscopy; and 3—describe a systematic guttural pouch endoscopic examination with practical keys to help identification of the underlying vital structures. Our investigation provides new practical information on guttural pouch endoscopic anatomy and has allowed us to identify structures that were not previously described. We believe that this information may help with an accurate diagnosis in some cases and also potentially reduce iatrogenic trauma to important structures. Full article
