“…In our cases, respiratory disease signs and fever were recorded in 12/22 dogs during spring or summer season: these historical findings could be useful for the clinician approaching dogs with this clinical condition. Acute inhalation can go unnoticed by the owner, resulting in subsequent migration through the airways into the lung and then into the pleural space, pericardium, retroperitoneal cavity, iliopsoas muscles, or out through the thoracic/abdominal wall [ 15 , 20 , 21 , 25 – 29 ]. This unidirectional migratory characteristic of grass awns is attributable to their backward-pointing barbs and fusiform shape [ 15 , 20 , 21 , 25 – 29 ].…”

“…Left and right iliopsoas muscle regions were scanned in a cranial to caudal direction with the scan plane held parallel and then perpendicular to the spine. Where possible, the plant material was identified, based on specific, previously described, imaging criteria [ 15 , 17 , 20 – 22 ]. Subsequently, adjacent anatomical landmarks (e.g., kidneys, aorta, caudal vena cava, renal arteries and their distance from the suspected foreign body) were identified to help the surgeon during intra-abdominal exploration.…”

BackgroundMigrating plant material is often suspected clinically to be the underlying cause of iliopsoas myositis in the dog, but cannot always be found pre- or intraoperatively. In most cases, recurrence of clinical signs is related to failure to remove the plant material. Preoperative ultrasonography can be useful to visualize migrating plant material and to determine anatomical landmarks that can assist in planning a surgical approach. The purpose of the present study was to report the role of intraoperative (intra-abdominal) ultrasonography for visualizing and removing the plant material from iliopsoas abscesses using a ventral midline laparotomy approach.ResultsA retrospective case series of 22 dogs with iliopsoas muscle abnormalities and suspected plant material was reported. Preoperative visualization and subsequent retrieval of the plant material was performed during a single hospitalization. In all 22 dogs, the plant material (including complete grass awns, grass awn fragments and a bramble twig) was successfully removed via ventral midline laparotomy in which intraoperative ultrasonography was used to direct the grasping forceps tips to the foreign body and guide its removal. In 11 of these 22 dogs, the plant material was not completely removed during prior surgery performed by the referring veterinarians without pre- or intraoperative ultrasonography. Clinical signs resolved in all dogs and all dogs resumed normal activity after successful surgical removal of the plant material.ConclusionIntraoperative ultrasonography is a safe and readily available tool that improves success of surgical removal of plant material within the iliopsoas abscesses via ventral midline laparotomy. Moreover, ultrasonographic findings of unusual plant material can be useful in planning and guiding surgical removal, by providing information about the size and shape of the foreign body.

“… 10 Masseter thickness values have been reported in patients with temporomandibular disorder, 12 facial asymmetry, 16 bone lesion, 22 and foreign body removal. 23 Because the masseter muscle is located on the surface layer, it can easily be measured by ultrasonography. However, ultrasound is not widely used as a method of measurement in this context.…”

PurposeThe purpose of this study was to evaluate the relationship between masseter muscle thickness, facial morphology, and mandibular morphology in Korean adults using ultrasonography.Materials and MethodsUltrasonography was used to measure the masseter muscle thickness bilaterally of 40 adults (20 males, 20 females) and was performed in the relaxed and contracted states. Facial photos and panoramic radiography were used for morphological analyses and evaluated for correlations with masseter muscle thickness. We also evaluated the correlations of age, body weight, stature, and body constitution with masseter muscle thickness.ResultsIn the relaxing, the masseter was 9.8±1.3 mm in females and 11.3±1.2 mm in males. In the contracted state, it was 12.4±1.4 mm in females and 14.7±1.4 mm in males. Facial photography showed that bizygomatic facial width over facial height was correlated with masseter muscle thickness in both sexes in the relaxed state, and was statistically significantly correlated with masseter muscle thickness in males in the contracted state. In panoramic radiography, correlations were found between anterior angle length and posterior angle length and masseter muscle thickness in females, and between body length and posterior angle length, between anterior angle length and body length, between ramal length and body length, and between body length and condyle length in males.ConclusionMasseter muscle thickness was associated with facial and mandibular morphology in both sexes, and with age in males. Ultrasonography can be used effectively to measure masseter muscle thickness.

“…The clinical syndromes produced by grass awn migration are varied as evidenced by the numerous locations in which the awn may lodge and the resultant clinical manifestation produced [2]. Within the eye, grass awns usually lodge in the conjunctiva or nictitating membrane [2,21], while more, in general, grass awns usually lodge in the external ear canal, causing, in some cases, the rupture of the tympanic membrane, or in interdigital spaces, causing draining tracts; grass awns could also be frequently found in the respiratory and also in the thoracic cavity [17][18][19][21][22][23][24].…”

Penetrating palpebral grass awn in a dog

et al. 2017

An unusual case of a penetrating grass awn in an eyelid of a dog is reported. A 6-month-old mixed breed dog was referred to the Ophthalmology Unit of the Veterinary Teaching Hospital of Camerino University for anorexia, lethargy, left monolateral ocular swelling and pain to the left eye, present from 1 month. Ophthalmic examination of the left eye showed copious and purulent discharge, and ultrasonography revealed the presence of an abscess containing a grass foreign body. The grass awn was surgically removed. Three days after surgery, the dog showed a marked improvement, with a total resolution obtained in 7 days. To the authors' knowledge, penetrating foreign bodies such as the one of this paper have never been described before in literature.Keywords Dog Á Foreign body Á Grass awn Á Lid abscess Á Swollen eyelid Á Ultrasonography Riassunto Questo articolo descrive un particolare caso di corpo estraneo palpebrale di origine vegetale Un cane meticcio di sei mesi di età è stato riferito all'Unità di Oftalmologia dell'Ospedale Veterinario Didattico dell'Università di Camerino per la presenza di anoressia letargia e tumefazione oculare monolaterale sinistra associata a dolore presenti da un mese. L'esame oftalmologico dell'occhio sinistro ha messo in evidenza la presenza di abbondante essudato purulento e la valutazione ultrasonografica ha mostrato la presenza a livello palpebrale di un ascesso contenente un corpo estraneo vegetale che è stato rimosso chirurgicamente. Tre giorni dopo la chirurgia il cane già manifestava un marcato miglioramento con una guarigione completa dopo una settimana. In bibliografia non sono stati mai descritti corpi estranei vegetali penetranti a livello palpebrale come quello riportato nel presente articolo.
