Equine odontoclastic tooth resorption and hypercementosis
No full textOral and dental diseases are common occurrences in horses. Nevertheless, dental disease are often not apparent and the short dental examination as part of general clinical evaluation is not enough to detect dental problems. Several instrumental investigations are now available beside direct oral examination in horse.
During the last years, a poorly described disorder of incisor and canine teeth and their periodontal ligament, with resorptive and proliferative changes of the calcified dental tissues, has recently been documented in aged horses (i.e. older than 15 years). Clinical signs were enlargement of the gingival area, occasionally associated with ulcerations and purulent discharge, painfulness and tooth mobility.
A chronological sequence of odontoclastic resorption followed by hypercementosis was demonstrated. EOTRH shares many features with similar dental syndromes described in humans (MIRR) and cats (FORL).
No plausible aetiopathogenesis for this syndrome has been recorded. An aetiological hypothesis proposes mechanical stress of the periodontal ligament as the initiating facto
Paranasal sinus cysts in the horse : Complications related to their presence and surgical treatment in 37 cases
No full textBackground Paranasal sinus cysts (PSC) are a common cause of equine secondary sinusitis. The outcome and associated complications have not been frequently reported. Objectives Study design To review the associated clinical signs, associated morbidities and outcomes of horses treated for PSC. Retrospective multicentre case series. Methods Results Retrospective analysis of case records and telephone follow up survey. Subjects were 37 horses 1-24 years old that were presented with nasal discharge (n = 31), facial swelling (n = 25) and epiphora (n = 19). Radiography and computed tomography allowed identification of the cyst-induced changes including concomitant tissue destruction (n = 31), leading among other things to local nerve damage causing headshaking (n = 6) and unilateral blindness (n = 1). Radiographic changes to adjacent dental apices were present in 10 horses. Horses over 10 years old showed more of the named associated problems. Post-operative complications included surgical site infection (SSI) (n = 11), nasofrontal suture periostitis (n = 6) and sequestration (n = 1) following removal of the PSC via osteotomy. The long-term response to treatment was available for 28 cases with 22 horses (78.6%) fully cured, 4 (14.3%) partially cured and 2 (7.1%) not responding to treatment. In 7 horses (18.9%) there was recurrence of the cyst post-operatively. Main limitations Conclusions Due to the study being a multicentre retrospective case series with collection of data over an extended period, there may be inconsistency in data recording and absence of reporting of some findings. Overall, the diagnosis and treatment of sinus cysts is relatively straightforward and carries a good prognosis. In long-standing cases complications secondary to the expansive growth of cysts will dramatically affect the prognosis for full recovery due to pressure-induced changes to facial bones, cheek teeth and nerves. These secondary complications mainly occurring in older horses may be due to a combination of a relatively longer period of affection and the inflexibility of older horses' bones. Cyst recurrence following treatment can occur in up to 19% of cases
Hypothermia prevention in long‐standing equine dental procedures
No full textHypothermia is a common, detrimental post-operative complication in man and veterinary medicine. Active warming strategies are paramount for prevention and treatment. Duration of operations, administered drugs and their adverse effects put horses undergoing procedures requiring long-standing sedation in danger of hypothermia. The aim of this study was to investigate whether an air warming device would be helpful to avoid severe hypothermia in adult horses. Twenty client-owned horses undergoing dental/sinusoidal procedures were divided into two equal groups. The treatment group was covered with a warming blanket connected to the warming device with the temperature set to 43°C. Horses in the control group were not blanketed. Temperature was measured at the time of first sedation (T0) and every hour throughout the length of the procedure. Use of the warming blanket was straightforward and caused no adverse reactions. The mean decrease in body core temperature in the treatment group was significantly less than the mean temperature decrease in the control group, beginning at the second hour of the procedure. No horse in the treatment group reached a body temperature below 36°C. Overall loss of temperature in the control group was more than double when compared with the treatment group (1.5°C and 0.7°C respectively). The use of an active air warming blanket in horses is an easy technique to prevent hypothermia in horses undergoing long-standing sedation procedures

No full texteditorial reviewedSinus suture periostitis, suture exostosis, suture separation, or suturitis is an uncommon condition that should be included in the differential diagnosis of equine facial swelling. Horses affected with suture periostitis develop uni- or bilateral, firm, non-painful swelling in the frontal region of the head. The exact location of the swelling is dependent on the facial sutures affected. The problem is usually diagnosed from clinical signs and radiographs. Radiographs often reveal a radiolucent suture line surrounded by an area of increased opacity and callus formation. Due to the complex 3-D anatomy of the head and problems with superimposition of multiple bony structures, CT offers better imaging of the problem. 59 cases were catalogued. Swelling developed after sinus surgery (20 cases), following trauma to the head (17 cases), reported with underlying sinus pathology (8 cases) or was classified as idiopathic swelling (14 cases). The present case series shows that conservative management of these cases will rarely lead to full clinical resolution of the pathology. Spontaneous disappearance was reported in a number of cases within a 6-month timeframe (except one case where it took 1.5 years), initiating surgical treatment could be delayed in idiopathic cases until after this timeframe. This current case series also demonstrates the importance of the presence of bone sequestrates that may be

Malignant melanoma in a equine: report of a case
No full textEl objetivo de este trabajo fue relatar un caso de melanoma en un equino cruceto cuarto de milla, macho, de 10 años de edad, color moro, el cual fue llevado a la clínica de la Universidad de los Llanos por una masa en el parpado derecho que imposibilitaba su visión por dicho ojo, en Marzo del 2010. En este relato de caso, enfatizamos en signos clínicos; exámenes paraclínicos, tales como hemograma, biopsia excisional e histopatología, así como el tratamiento instaurado al animal.The aim of this study is to report a case of melanoma in a quarter-mile horse cross, male, 10 years of age, moor color, which was taken to the clinic of the Universidad de los Llanos by a mass in the right eyelid which prevented his vision for that eye in March 2010. In this case report, we emphasize on clinical signs, laboratory tests such as CBC, excisional biopsy and histopathology, and introduced to animal treatment
