Surgical Treatment of an Abdominal Abscess Caused by a Migrating Iron Wire From the Ventral Colon,a Case Report

A 13-year-old mare presented for evaluation of recurrent colic episodes. The horse was diagnosed with a mass within the spleen at the ultrasound examination of the abdomen; the levels of Serum Amyloid A and the fibrinogen were high and so a presumptive diagnosis of an abscess involving the spleen was made base on clinical, ultrasonographic and laboratory findings and it was decided to perform n exploratory laparotomy for a definitive diagnosis and possible treatment. Upon abdominal exploration a mass involving the spleen, the lateral wall of the ventral colon adherent to the left abdominal wall was diagnosed and with an intraoperative ultrasound examination a linear hyperechoic foreign body was diagnosed within the mass. It was removed through an enterotomy of the left ventral colon that allowed the digital exploration of the mass without spilling of pus within the peritoneal cavity. The horse was discharged and the long term follow-up revealed no complications and no more signs of abdominal pain.

Imaging diagnosis: pneumothorax and focal peritonitis in a dog due to migration of an inhaled grass awn

A 1-year-old working Kelpie developed pneumothorax and focal peritonitis after inhalation of a grass awn that migrated from the lung, through the diaphragm, into the peritoneal cavity. Radiographic evidence of sternal lymph node enlargement was fundamental in the diagnosis of intraperitoneal disease and prompted abdominal ultrasound leading to definitive diagnosis.     

Brain Abscess in a 4-Month-Old Filly: A Case Report

Although recognized as a possible complication to sepsis, there are few published reports on brain abscesses in foals. This case report describes a 4-month-old Icelandic filly that, as a neonate, had a history of pyrexia and lameness, which resolved with antibiotic treatment. Approximately 3 months later, the foal developed neurological signs which were initially attributed to trauma; she was referred for further investigation. The clinical signs were consistent with a lesion of the right forebrain. Computed tomography examination revealed a mass, approximately 6 cm in diameter, located in the right cerebral hemisphere craniolateral to the right lateral ventricle. Because of the poor prognosis, the foal was killed, and a postmortem was performed. The findings confirmed the presence of an abscess of the right cerebral hemisphere, leading to severe atrophy of the cortex and dilation of both lateral ventricles. The left hemisphere was moderate-to-severe atrophic and had displaced to the left. Streptococcus equi subspecies zooepidemicus was isolated in pure culture from the abscess. The clinical features of the foal were compared with the pathological findings.     

Nitrate Poisoning in Horses Associated With Ingestion of Forage and Alfalfa

This report describes nitrate poisoning observed in thoroughbred mares. Nine horses died at a farm in Bursa, Turkey, between February and April of 2008. Five of them were pregnant. Clinical findings developed over a short period and included severe abdominal pain, limited response to analgesics and antispasmodics, diarrhea, shallow and rapid breathing, tachycardia, blue-brown discoloration of the mucosal membranes, tremors, ataxia, convulsions before death, and abortion in the pregnant mares. The main postmortem finding was chocolate brown–colored blood as well as congestion and inflammation of the intra-abdominal organs. Uterine rupture, colonic ruptures, and torsio uteri were seen in the pregnant mares. Stomach and intestinal ruptures were seen in four nonpregnant mares. High nitrate concentrations were determined in some grass and alfalfa samples used to feed the animals. Nitrate poisoning is considered to be very rare in horses, but, in this case, the clinical symptoms, postmortem findings, and nitrate levels in the collected samples supported nitrate and nitrite poisoning as the cause of deaths.     

Orbital cellulitis and intraocular abscess caused by migrating grass in a cat

We report an unusual case of orbital cellulitis in a cat. Drainage via the pterygopalatine fossa and medical treatment were performed. Failure of resolution and loss of ocular structure and visual function with a poor prognosis led to enucleation. During surgery, plant material and purulent exudate were present in the orbit. Histopathology showed an intraocular foreign body of grass that had migrated through the sclera causing a suprachoroidal abscess with choroidal and retinal detachment.

Carbon Dioxide Laser Keratectomy as a Treatment Option for Equine Corneal Stromal Abscessation: A Comparison to Lamellar Keratectomy and Penetrating Keratoplasty

Carbon dioxide (CO₂) laser keratectomy was compared to lamellar keratectomy (LK) and penetrating keratoplasty (PK) as a potential treatment option for equine corneal stromal abscessation. The medical records of 35 client owned horses undergoing surgical management of stromal abscessation were reviewed. Among those 17 underwent LK, 3 PK and 15 CO₂ laser keratectomy. Healing of the stromal abscess was achieved in all treated eyes. Those horses undergoing CO₂ laser keratectomy demonstrated few complications, and the time to healing and cosmetic outcome was comparable to those horses undergoing LK and PK.     

Everted third eyelid cartilage in a cat: a case report and literature review

An 8-year-old neutered female British Blue cat was presented with a presumed diagnosis of a prolapsed nictitans gland and associated ocular irritation and epiphora. However, during surgery, the apparent nictitans gland protrusion was determined to be an everted cartilage of the nictitating membrane. The scrolled portion of the cartilage was removed through an incision through the conjunctiva on the bulbar aspect of the third eyelid, as previously described in the dog. This operation resolved the ocular irritation occurring, and the third eyelid returned to its anatomically correct position.     

Fibrinonecrotic Placentitis and Abortion Associated With Pantoea agglomerans Infection in a Mare

Pantoea agglomerans, family Enterobacteriaceae, is a Gram-negative bacterium that may be isolated from soil and from plants. This bacterium has been associated with disease in plants, humans, and rarely in domestic animal species. We describe here a case of fibrinonecrotic placentitis and equine abortion associated with P. agglomerans infection in southern Brazil. A fetus with 10 months of gestation and its placenta were evaluated. Gross lesions were observed in the cervical star extending to the body of the chorioallantois and consisted of a focally extensive, transmural, severely thickened yellow area. Histologically, this area in the chorioallantois was effaced by severe necrosis, associated with marked inflammatory infiltrate of neutrophils and abundant deposition of fibrin and cellular debris. Aggregates of bacterial rods were noted intermixed with inflammation areas. No significant lesions were observed in the remaining organs inspected. Tissue samples of the lung, placenta, and stomach contents were cultured, and microbiological tests revealed the growth of P. agglomerans in all evaluated samples. The present study reaffirms the participation of P. agglomerans as a cause of bacterial placentitis and abortion in horses.

Listeriosis in Sheep: Listeria Monocytogenes in Sheep Fed Hay Or Grass Silage During Pregnancy. Immunological State,White Blood Cells,Total Serum Protein and Serum Iron

A comparison was made between a hay fed group, consisting of 23 ewes, and a grass silage fed group of 22 ewes, all pregnant. Excretion of Listeria monocytogenes (Lm) in the faeces and milk, antibody titres in sera and whey and delayed hypersensitivity against Lm, and several blood components were determined. The animals had previously been exposed to Lm, and Lm was isolated from the faeces from several animals when the experiment started.No significant difference in number of excretors between the 2 groups was found during the experimental period. The haemagglutination titres in both sera and whey were low and on the same level in both groups. The titres were higher in animals with 1 foetus than in animals with more than 1 foetus.In the first part of the experimental period the silage group had a reduced number of lymphocytes, lower total serum protein values and higher serum iron values, compared with the hay group.The silage group also had a stronger delayed hypersensitivity reaction against Lm than the hay group, and in the silage group the reaction was significantly stronger in ewes with 3 or more foetuses than in ewes with 1 foetus.In conclusion, the combined effect of some of the changes found in animals fed grass silage may leave them more susceptible to infections.     

Treatment and ophthalmic sequelae in a horse with facial cellulitis and orbital abscess

A 22‐year‐old Quarter Horse gelding with a history of dental (107) extraction 2 weeks previously was presented with facial cellulitis and an orbital abscess. The abscess was drained surgically dorsally and ventrally to the zygomatic arch and the horse was treated with parenteral antimicrobial and anti‐inflammatory drugs. The affected eye was protected with a temporary tarsorrhaphy and treated via a subpalpebral catheter. Six months after presentation, the horse was in excellent general condition and returned to previous level of exercise but showed blindness on the affected side. Pallor of the optic disc and severe attenuation of the retinal vessels, suggestive of optic disc atrophy, were present.
