Migrating grass awn within the intraconal part of the retrobulbar space in a dog

AbstractA 12 year old male Fox Terrier (case 1) and a one year old female Poodle (case 2) were presented with a history of dysorexia and vomiting, and case 2 also with distress associated with eating. Both dogs were diagnosed with acute pancreatitis based on clinical signs, blood analysis and ultrasonography which revealed the presence of a vegetable foreign body in the proximity of the pancreatic right lobe. Laparatomy enabled the gramineae awns to be removed which led to full resolution of clinical signs. We believe that these are the first reported cases of acute pancreatitis due to grass awns.

Local Anesthetic Solution

Background/Aim. Sub-Tenon's block is nowadays commonly used in ophthalmic surgery because of its safety and efficacy. The aim of this study was to investigate the distribution of the anesthetic solution with different amounts of hyaluronidase in the retrobulbar space, following an injection into the Sub-Tenon's space. Methods. In this experimental study, 40 pig cadaver heads were used (80 eyeballs). The material was divided into four groups (of 20 eyeballs each). Each group was administered 4.5 ml of a mixture of 2% lignocaine, 0.5% bupivacaine, and 0.5 ml of Indian ink, with different amounts of hyaluronidase - 15 IU/ml, 75 IU/ml, 150 IU/ml, except the control one. Samples of retrobulbar tissue were analyzed using the standard histopathological procedure. After that, they were also analyzed using the Adobe Photoshop program? (Windows, USA). The retrobulbar space was divided into eight zones by four perpendicular lines, which crossed in the centre of the optic nerve. The presence of ink in fat and muscle tissues and in the sheath of the optic nerve was observed. Results. The presence of the local anesthetic solution was significantly higher in inferonasal and superonasal quadrants of the fat and muscle tissues (p < 0.01). The distribution in optic nerve sheath is similar in each quadrant. Distribution of local anesthetic in each zone of the muscle tissue (I-VIII) was strongly influenced by the amount of hyaluronidase added. In the fat tissue, the distribution of local anesthetic under the influence of hyaluronidase was significantly higher (p < 0.05) in the areas which were distant from the place of injection (I-IV). The distribution in the optic nerve sheath is significantly higher (p < 0.01) in the group with 150 IU/ml of hyaluronidase. Conclusions. Following a sub-Tenon block local anesthetic was present in the retrobulbar space in a high percentage of the cases. The presence of local anesthetic solution in retrobulbar space depends on the amount of hyaluronidase previously added to the local anesthetic.

Grass Awn

SummaryA two-year-old female Lucerne Hound was presented with a one-week history of signs of progressive neck pain, inappetence, apathy, and an elevated rectal temperature. Findings of magnetic resonance imaging (MRI) were consistent with a foreign body abscess in the epidural space at the level of the first and second cervical vertebrae. A leftsided dorso-lateral atlantoaxial approach was performed, revealing an epidural abscess containing a grass awn. The clinical signs resolved within three days of surgery and the dog made a full recovery. This case report shows that grass awns can migrate to the atlantoaxial region in dogs and MRI findings lead to a suspicion of caudo-cranial migration within the spinal canal.

Purpose. To study the clinical efficacy of complex treatment of optic neuritis (ON) associated with herpesvirus infection (HVI), including methods of immunotherapy. Material and methods. The clinical study involved 37 people (37 eyes) with acute ON associated with HVI. The treatment regimen for all patients within 10 days included delivery through irrigation system implanted into the retrobulbar space to optic nerve: solutions Dexamethasone on decreasing scheme, Emoxypine 1% 0.5 ml and Dicynone 12.5% 0.5 ml, in combination with administration of drugs neuroprotection. All patients were divided into 2 groups depending on characteristics of therapy. The 1st group consisted of 17 patients, who were treated according to the standard method. 2nd group consisted of 20 patients who received additional intramuscular Imunofan in the regimen and doses according to the manufacturer's instructions. Results. Analysis of obtained datas showed that more significant positive dynamics was noted in the clinical course of ON in patients of the 2nd group of observation in comparison with the 1st group. Conclusion. The strategy of etiotropic and pathogenetic immunotherapy at ON, associated with HVI infection, developed by us, allows to shorten recovery time and improve functional results of treatment in absence of relapses of disease within 1 year of follow-up. Key words: optic neuritis, herpesvirus infection, corticosteroid therapy, immunotherapy.

Grass Awn

A 13-year-old male mixed-breed dog was examined because of hematuria and pyrexia. Ultrasonographic examination of the genitourinary tract showed the presence of a migrating grass awn in the right prostatic lobe. Laparotomy allowed, under ultrasonographic guidance, to remove entirely the migrating grass awn from the prostatic parenchyma. The recovery was uneventful and four months after the surgery the owner reported that the dog showed the complete resolution of the clinical signs and full return to normal activity. To our knowledge, this case report describes for the first time the clinical presentation, imaging findings, management and outcome for a dog with prostatic localization of a migrating grass awn.
