Effects of multimodal environmental modification in crystal-related feline lower urinary tract diseases / Efeitos da modificação ambiental multimodal em felinos com cristais doenças do trato urinário inferior relacionadas a cristais

This study aims to analyze the effects of multimodal environmental modification (MEMO) of cats with recurrence of lower urinary tract signs (LUTS). Treatment of FLUTD included pharmacological treatment, dietary management, and multimodal environmental modification approaches. Twenty client-owned indoor-housed cats with recurrence of lower urinary tract signs had been covered in this observation. Diagnosis of lower urinary tract was made primarily based on the cat's clinical signs, results of laboratory parameters, urinalysis and ultrasonographic examination. Cats were divided into two groups as cefovecin (8 mg/kg sc, single time use) + meloxicam (0.1mg/kg q24h, 3 days) + dry food including l-tryptophan and milk protein hydrolysate to dissolve struvite stones (Group 1) and cefovecin + meloxicam + dry food including l-tryptophan and milk protein hydrolysate to dissolve struvite stones + multimodal environmental modification (Group 2). Clinical and urinary parameters are scored as 0, 1, 2, 3 or 4 points on initial, third, seventh days. Scores of clinical parameters were significantly different between (p<0.05) group 2 and group 1 on the third and seventh days and scores of urinary parameters are significantly different between (p<0.05) group 2 than group 1 on the seventh day. Clients who were contacted after 1 year reported that they did not see any clinical signs of urinary tract diseases.

Este estudo tem como objetivo avaliar os efeitos da modificação ambiental multimodal (MEMO) em gatos com recorrência de sinais do trato urinário inferior (LUTS). O tratamento da FLUTD incluiu tratamento farmacológico, controle dietético e abordagens de modificação ambiental multimodal. Vinte gatos de propriedade de clientes, alojados em ambientes fechados, com recorrência de sinais do trato urinário inferior foram incluídos nessa observação. O diagnóstico do trato urinário inferior foi feito principalmente com base nos sinais clínicos do gato, nos resultados dos parâmetros laboratoriais, na urinálise e no exame ultrassonográfico. Os gatos foram divididos em dois grupos: cefovecina (8 mg/kg sc, uso único) + meloxicam (0,1mg/kg q24h, 3 dias) + ração seca incluindo l-triptofano e hidrolisado de proteína do leite para dissolver cálculos de estruvita (Grupo 1) e cefovecina + meloxicam + ração seca incluindo l-triptofano e hidrolisado de proteína do leite para dissolver cálculos de estruvita + modificação ambiental multimodal (Grupo 2). Os parâmetros clínicos e urinários foram pontuados como 0, 1, 2, 3 ou 4 pontos no primeiro, terceiro e sétimo dias. As pontuações dos parâmetros clínicos foram significativamente diferentes entre (p<0,05) o grupo 2 e o grupo 1 no terceiro e sétimo dias, e as pontuações dos parâmetros urinários foram significativamente diferentes entre (p<0,05) o grupo 2 e o grupo 1 no sétimo dia. Os clientes que foram contatados após um ano relataram que não observaram nenhum sinal clínico de doenças do trato urinário.

Carcinoma de células escamosas em gato - tratamento com quimioterapia metronômica / Squamous cell carcinoma in a cat - treatment with metronomic chemotherapy

Background: Squamous cell carcinoma (SCC) is a malignant neoplasm associated with prolonged exposure to ultraviolet light and lack of skin pigment in white-coated animals. The disease diagnosis is based on the animal's history, clinical signs and histopathology of the samples collected. The therapeutic alternatives are diverse. Among them, one of the most used is the metronomic chemotherapy which is based on the use of cytostatics drugs, applied in low and frequent doses for a longer period of time. One of the mechanisms of action of this type of therapy is the decrease in angiogenesis. Non-steroidal anti-inflammatory drugs (NSAIDs) are simultaneously used to maximize the angiogenic effect. The objective of this study is to report the results of a treatment accomplised with metronomic chemotherapy (cyclophosphamide with meloxicam) in a domestic feline which presented a squamous cell tumor. Case: A 7-year-old female cat, mixed breed, not neutered, weighing 3.5 kg, was assisted at the Veterinary Specialties Teaching Clinic (CEEV) of the Technical University of Machala (UTMACH), presenting bilateral ulcerative lesion in the nasal plane for 5 months. Chronic exposure to sunlight is referred to in the patient's anamnesis. Aspiration cytology performed in the patient revealed an inflammatory process with a predominance of neutrophils and macrophages, and showed absence of neoplastic cells. A treatment based on antibiotics and corticosteroids was adopted. As there were no favorable results, an excisional biopsy procedure was chosen to collect the affected tissues. The result of the histopathological analysis was a level 2 squamous cell carcinoma (SCC). The initial treatment consisted of surgical removal of the tumor and later the use of metronomic chemotherapy based on Cyclophosphamide, Meloxicam, DHA (docosahexaenoic acid) and Sucralfate for 5 months was adopted. At the beginning of the second phase of treatment, the patient developed a macula that progressively diminished. Currently, the patient does not have any recurrence of the diagnosed neoplasm. Discussion: The diagnosis of squamous cell carcinoma was based on clinical and histopathological findings. The macroscopic lesions were crusted ulcers that do not heal in the nasal plane and auricular pavilion, as reported in the literature. SCC is characterized by the infiltration of squamous cells in the dermal layer of the skin, forming epithelial islands with keratin pearls. The histopathological findings of this case present the same characteristics. The climatic conditions of Ecuador, high temperatures with greater incidence of sunlight, hypopigmented areas of the animal's body and chronic exposure to solar radiation are risk factors present in this case that foster the development of this malignant neoplasm. There are multiple treatments to be introduced in this sort of pathology. In this case, surgical removal of the tumor was adopted, followed by metronomic chemotherapy based on cyclophosphamide at 10 mg/m2 and meloxicam at a 0.05 mg/kg per day for a period of time of five months, obtaining favorable results and absence of recurrence. Despite metronomic chemotherapy being easy to administer, with fewer side effects, which includes a better acceptance of care takers who are reluctant to administer conventional chemotherapy, further studies are still necessary in what concerns certain variables such as age, carcinoma level, appropriate dosages and drugs according to each neoplasm.

Lesão facial grave em um gambá-de-orelha-branca (Didelphis albiventris) - tratamento com ozonioterapia / Severe facial wound in a white-eared opossum (Didelphis albiventris) - treatment with ozone therapy

Background: Ozone therapy (OT) is a type of treatment that uses ozone gas, which has high oxidizing power. OT has been utilized for various diseases and to accelerate the wound healing process and reduce inflammation. Additionally, OT is a low-cost treatment recommended for patients that can be easily restrained. There are several methods of ozone administration, including topical use through bagging, cupping, or rectal insufflation, in addition to ozonated autohemotherapy. Based on the benefits of OT and the scarcity of reports describing its effects on white-eared opossums (Didelphis albiventris), we report on the use of ozone in the treatment of a severe facial wound in a white-eared opossum. Case: An adult female white-eared opossum weighing 1.6 kg was rescued from a fire. The patient was pregnant, dehydrated, hypothermic and had an extensive burn wound in the facial region. Due to the stress of captivity and its aggressive behavior, the animal needed to be chemically restrained with dexmedetomidine and butorphanol. Following sedation, the cephalic vein was catheterized and intravenous fluid therapy with ringer lactate was started to treat dehydration. Next, enrofloxacin, meloxicam, and tramadol hydrochloride were administered. Body rewarming was performed with thermal bags. The microbial load of the wound was reduced with chlorhexidine degerming solution followed by washing with saline solution. A thin layer of silver sulfadiazine cream was applied to the wound area. Over the following days the patient was treated with OT using the cupping technique combined with ozonated sunflower oil. After the first applications there was an improvement in the appearance of the wound, which initially had a purulent aspect. After 20 days of treatment the wound showed good granulation and there were no signs of infection, and at 45 days of treatment it was completely healed. The patient was then released with her baby. Discussion: Ozone therapy was included in the patient's treatment plan to enhance the tissue repair process in order to reintroduce the animal to the wild in the shortest possible time. The strategy was successful in improving healing and reducing tissue inflammation and infection. Ozone is known to cause the inactivation of microorganisms as a result of the oxidation of phospholipids and lipoproteins present in the cell membrane of bacteria and to interrupt viral replication. Ozone helps in the perfusion of injured tissues, contributing to the entry of humoral components, which control inflammation. Moreover, ozone contributes to increase supply of oxygen and nutrients to tissues and to stimulate increased production of fibrinogen and formation of granulation tissue. Ozone increases the enzymatic antioxidant response, while also playing a role in immunoregulation. Ozone can be used in several ways and via various methods with potential routes including intravenous, urethral, intramuscular, subcutaneous, or intra-articular, in addition to rectal and intramammary insufflation. Immunomodulatory, anti-inflammatory, analgesic, and antiseptic effects can be achieved with different doses and concentrations, which enables its application in different types of pathologies. Because of the aggressive behavior of the animal, in the current case we opted for the cupping technique combined with ozonated oil, both techniques which can be administered easily with only physical restraint of the patient. Cupping allows for the provision of a higher concentration of ozone gas locally whereas the ozonated oil maintains the effect of the gas for slightly longer, enhancing its effect and promoting tissue repair. The present report showed that OT is an effective alternative for the treatment of burn wounds in opossums, without causing adverse effects to the patient or her baby.

Pilomatricoma benigno em cão da raça Shih-Tzu / Benign pilomatricoma in a Shih-Tzu dog

Background: Pilomatricomas are neoplasms of hair follicles, located in the hair bulb, and the incidence is uncommon in the clinical-surgical clinical routine of dogs and cats. It commonly affects adult animals, with no predisposition to sex or race, and is mainly located in the neck, back, and tail region. The diagnosis is made by histopathological examination, where cells are observed in which their nucleus does not stain with hematoxylin and eosin - empty nucleus. The present work aimed to report a case of benign pilomatricoma since it is a rare condition in dogs and cats and, consequently, there is little information in the literature. Case: A 6-year-old male Shih-Tzu dog, not submitted to surgical contraception, weighing 6.9 kg, was treated at the Veterinary School Hospital (HVE) of the North Parana State University (UENP), Bandeirantes, PR, Brazil, with a history of nodules in the tail region, lasting 6 months. On physical examination, no changes were identified in the patient's physiological parameters. However, the presence of neoformations in the distal and medial region of the tail, similar to a nail, adherent, non-ulcerated and non-alopecic, and absence of pruritus or self-mutilation were identified. Vaccination and deworming were updated. Hematological examination, serum biochemicals (urea, creatinine, alanine aminotransferase, alkaline phosphatase, and albumin), and abdominal ultrasound showed no changes. According to the clinical and laboratory signs, it was decided to perform an excisional biopsy, using a caudectomy, for subsequent histopathological examination. The specimens were fixed in 10% formaldehyde and sent for histopathological examination. Histological examination was compatible with benign pilomatricoma. Postoperatively, cephalexin, dipyrone, tramadol hydrochloride, and meloxicam were prescribed, surgical wound cleaning, and the use of an Elizabethan collar until the suture was removed. After 10 days of the surgical procedure, the patient was asked to remove the sutures, and no changes were identified regarding the physiological parameters and blood count. Discussion: Pilomatricomas are commonly benign neoplasms arising from the germ cells of the follicular matrix. They present dermal or subdermal forms, with several cystic structures which are surrounded by keratinocytes, similar to the matrix cells of an anagen hair follicle, more keratinized and firmer areas, corroborating the results of the present report. In the ultrasound examination, the presence of intra-abdominal metastases was not identified, which is consistent with the literature, since in this type of neoplasm it is not common to identify foci of intra-abdominal and thoracic metastases. In the present report, immunohistochemistry was not used, even though it is used to differentiate follicular neoplasms from pilomatricomas. However, histopathological examination is considered the best method for the definitive diagnosis of pilomatricomas in dogs. It was concluded that the surgical treatment through excisional biopsy, with safety margins of 2 cm, was effective as a therapeutic method in the case of benign pilomatricoma, and the definitive diagnosis must be made through histopathological examination.

The analgesic effect of preventive administration of meloxicam in calves submitted to hot-iron dehorning / Efeito analgésico da administração preventiva de meloxicam em bezerros submetidos à descorna com ferro quente

Dehorning is a zootechnical practice that causes severe pain in cattle. Although there are several studies evaluating the effects of analgesics in calf dehorning, none of them used validated pain assessment instruments. We evaluated the analgesic effectiveness of meloxicam administered before dehorning, compared to a control group, using the Unesp-Botucatu, numerical, simple descriptive, and visual analogue scales for pain assessment before and 4, 8, and 24 hours after the dehorning in 44 female calves. All calves received 0.04 mg/kg of xylazine IM 20 minutes before dehorning and local anesthetic block with 2% lidocaine with a vasoconstrictor. Calves were divided into two groups: without (GX; n = 22) or with 0.5 mg/kg of meloxicam (GXM; n = 22) administered intravenously before the procedure. Dehorning was performed through the section of the base of the horn bud, followed by thermocautery disbudding. For comparisons over time, mixed linear or generalized mixed linear model were used. The interaction between groups and study phases was used as fixed effects and each calf as a random effect. Bonferroni post hoc test was used. There was an increase in the pain scores at 4h compared to baseline in both groups (GX and GXM) for the four scales. The scores at 4h were higher in GX compared to GXM for all scales. Meloxicam reduced, but did not eliminate, behavioral expressions of pain in calves submitted to hot-iron dehorning. Therefore, it should be included in the analgesic protocol to improve welfare in calves undergoing dehorning.

A descorna é uma prática zootécnica que causa dor intensa em bovinos. Há na literatura diversos estudos sobre os efeitos de analgésicos para mitigar a dor frente a descorna, mas nenhum usando escalas validadas. Avaliamos a eficácia do meloxicam administrado previamente à descorna, comparado a um grupo controle, utilizando-se as escalas Unesp-Botucatu, numérica, simples descritiva e analógica visual para avaliação da dor antes e 4, 8 e 24 horas após a descorna em 44 bezerros fêmeas tratadas com 0,04 mg/kg de xilazina IM 20 minutos antes da descorna e bloqueio anestésico local com lidocaína a 2% com vasoconstritor. Os bezerros foram alocados em dois grupos: sem (GX; n=22) ou com 0.5 mg/kg de meloxicam (GXM; n=22) administrado por via intravenosa antes do procedimento. Realizou-se a descorna por secção da base do botão cornual seguido de termocauterização. Para as comparações ao longo do tempo, empregou-se o modelo linear ou linear misto. Considerou-se a interação entre grupos e momentos como efeito fixo e cada bezerro como efeito aleatório. As alterações foram inferidas de acordo com o pós-teste de Bonferroni. Para as quatro escalas houve aumento dos escores às 4h comparado ao basal em ambos os grupos (GX e GXM). Os escores de todas as escalas às 4h foram maiores em GX que em GXM. O meloxicam reduziu, mas não aboliu, a expressão comportamental da dor em bezerros submetidos à descorna com ferro quente, o que sugere o uso de terapia antálgica multimodal para realizar tal procedimento e garantir o bem-estar animal.

Protocolo de sedação visando a castração química em cães / Sedation protocol aiming to chemical castration in dogs

A castração química é utilizada para castrar cães machos a um custo mais baixo que o procedimento cirúrgico, que é o método mais aplicado para castrar cães e gatos. A castração química é um procedimento mais simples que a castração cirúrgica e pode ser realizada a nível ambulatorial, sem necessidade de anestesia geral. Entretanto, devido ao estresse pela manipulação e ao desconforto produzido pela injeção de uma substância no interior dos testículos, faz-se necessária uma sedação para que a castração química seja efetuada de um modo que proporcione o bem-estar do animal. Assim, este artigo tem como objetivo propor um protocolo inovador para sedação de cães submetidos à castração química. Para isso, foram utilizados 12 cães submetidos à administração de xilazina em subdose no acuponto yin tang. Após o estabelecimento da sedação, os cães foram castrados quimicamente. O protocolo proposto permitiu que a castração química fosse realizada com conforto para o paciente e para a equipe de médicos veterinários. Desta forma, concluiu-se que o protocolo de sedação é seguro e pode ser empregado em cães para procedimentos não invasivos, como exames, coleta de material e outros processos ou técnicas semelhantes.

Chemical castration is used to spay male dogs at a lower cost than the surgical procedure, which is the most applied method to spay dogs and cats. Chemical castration is a simpler procedure than surgical castration and can be performed on an outpatient basis, without the need for general anesthesia. However, due to the stress caused by manipulation and the discomfort produced by the injection of a substance into the testicles, sedation is necessary so that chemical castration is to be carried out in a way that provides the animal's welfare. Thus, this article aims to propose an innovative protocol for sedation of dogs submitted to chemical castration. For this purpose, twelve dogs submitted to the administration of xylazine in subdosis in the yin-tang acupoint were used. After the establishment of sedation, the dogs were chemically neutered. The proposed protocol allowed chemical castration to be performed with comfort for the patient and the team of veterinarians. Therefore, it is concluded that the sedation protocol is safe and can be used in dogs for non-invasive procedures such as exams, material collection, and other similar processes or techniques.

Assessment of general activity and anxiety-like behavior in mice following tramadol and meloxicam administration for managing immediate post-operative pain

After analgesic administration, we evaluated general activity in the Open-Field and anxiety-like behavior in the Elevated Plus Maze of vasectomized mice. We divided C57BL/6J male mice into eight groups: saline, three non-operated control groups treated with 10 mg/kg meloxicam, 20 mg/kg tramadol, or both intraperitoneally, and four vasectomized mice groups treated with the same analgesic protocol as the control groups. One group of vasectomized mice received both treatments and an additional 10 mg/kg lidocaine at the incision site. We conducted the vasectomy via scrotal approach under isoflurane inhalation anesthesia and performed behavioral tests after full anesthesia recovery. Mice treated with meloxicam demonstrated low ambulation, spontaneous activity, and rearing frequency. Mice treated with tramadol showed spontaneous behavior compared with the saline control. Due to behavior changes demonstrated by meloxicam controls, we were unable to identify whether meloxicam provided adequate analgesia. Vasectomized mice treated with tramadol showed general activity behavior similar to their control but displayed significantly less rearing, suggesting that they were under potential signs of pain or discomfort. In conclusion, the Open Field test and the Elevated Plus Maze can usefully pre-evaluate analgesic protocols to identify possible interference caused by adverse drug effects. For future directions, an appropriate regimen of meloxicam and tramadol for enhancing mice welfare post vasectomy should be better investigated.

Fratura de úmero em uma curicaca (Theristicus caudatus) - manejo anestésico e cirúrgico / Humerus fracture in a buff-necked ibis (Theristicus caudatus) - anesthesia and surgical procedures

Background: The medical science of birds, with the exception of aviculture, has a very short history compared to other subdisciplines of veterinary medicine. With this in mind, the current work aims to report the case of a buff-necked ibis with an open fracture of the left humerus, presenting the surgical treatment and anesthetic protocol used, in order to contribute to the avian medical literature. Case: An adult buff-necked ibis (Theristicus caudatus) was referred to the University Veterinary Hospital with an open fracture of the left humeral shaft, 7 days after rescue. During the physical examination, a skin lesion was identified in the fracture area, with signs of low vascularization, devitalization, necrotic tissues, and purulent secretions being noted. On radiographic examination, the fracture was classified as comminuted, with exposure of the left humeral shaft. After evaluating the limb, it was decided to amputate the wing, and 24 h later, the patient was referred to the operating room after fasting for 4 h. As pre-anesthetic medication, ketamine (20 mg/kg) and midazolam (1 mg/kg) were administered, both intramuscularly. Orotracheal intubation was performed, after which the tracheal tube was connected to a Baraka-type gas-free system and the supply of isoflurane was started through a universal vaporizer, diluted in 100% oxygen. For transoperative analgesia, brachial plexus block was performed using 2% lidocaine (2 mg/kg). During the surgical procedure, an incision was made in the skin and subcutaneous tissue in the middle third of the left humerus, and detachment of the greater deltoid muscle was performed with a periosteal elevator, followed by excision of the tensor propatagialis. In the ventrodorsal region, circular ligation of the brachial vein, ulnar vein and artery, and median-ulnar nerve was carried out, and disarticulation of the scapulacoracoid-humeral region. Subsequently, abolition of dead space and a myorrhaphy were performed, followed by demorrhaphy. In the immediate post-operative period, morphine (5 mg/kg), meloxicam (0.1 mg/kg), and enrofloxacin (10 mg/kg) were administered intramuscularly. The patient was discharged from the hospital 6 h after the end of the surgical procedure. Discussion: Interest in the conservation of wild birds is one of the causes of the increased demand for anesthetic and surgical procedures in these species. However, it is a challenge for professionals in the field. The use of analgesics is recommended for reasons of well-being, but also because of the possibility of reducing the concentration of inhalational anesthetics in surgical procedures. Ketamine associated with midazolam promotes sufficient sedation and muscle relaxation in the patient, enabling safe preoperative management, in addition to reducing the amount of inhaled anesthetics used during the transoperative period. Isofluorane promotes safe general anesthesia for birds and has an advantage over injectable drugs, as it provides better dynamic control of anesthetic depth in these species. The brachial plexus block performed is a simple procedure that promotes quality anesthesia and analgesia in the perioperative period. The choice for amputation was due to the absence of musculature for closure, severe skin, muscle, and bone devitalization, and the infectious process in the region, factors that would prevent osteosynthesis. Although amputation through the bone is preferable, the disarticulation technique was used due to the absence of a healthy proximal humeral fragment. The patient's death can be explained by the poor nutritional status the bird was in, as it presented an open fracture with severe contamination, a concomitant injury that occurred during the possible trauma, and the excessive time between the day of the trauma and the day of medical attendance. However, the surgical and anesthetic procedures were adequate and satisfactory for the patient. The importance of identifying and treating diseases secondary to contaminated fractures in these species is emphasized.

Toxic systemic reaction after bee stings in a bitch

Background: Bee sting poisonings are common in dogs, and toxic systemic presentation may represent a life-threatening condition. Apis mellifera venom is a complex mixture of melitin, apamine, phospholipase, hyaluronidase and degranulating peptides, that causes local injury at the site of inoculation and multiple organ complications, including hemolysis, kidney injury, muscular damage, cardiovascular and respiratory complications. The present work reports a complete and detailed description of a dog's systemic toxic reaction to bee stings, including history, clinical signs, laboratory findings, emergency care and development, as well as possible association with later immunomediated arthritis. Case: A 6-year-old female German Shepperd suffered multiple bee stings. First care was conducted by a veterinary at the site, where he only received promethazine, meloxicam and dexamethasone. After 24 h and significant progression of symptoms, the animal was forwarded to a specialized veterinary hospital. The patient was evaluated throughout 9 days, and presented intense edema, respiratory distress, tongue necrosis and grade II of acute kidney injury. Extensive laboratory exams were conducted throughout the hospitalization. Main laboratory findings included polycythemia, leukocytosis by neutrophilia and monocytosis, thrombocytopenia and azotemia. Urinalysis evidenced turbid aspect, dark yellow color and intense proteinuria, reinforcing kidney damage. Abdominal ultrasound examination identified blood clots in the bladder, and liver with reduced echogenicity and echotexture, suggesting acute inflammation. Therapy aimed to stabilize the patient, control kidney damage and avoid anaphylaxis. Treatment included intensive care support, promethazine, hydrocortisone, dexamethasone, dipyrone, methadone, metronidazole, ampicillin, clindamycin and tramadol. Following successful treatment, the animal presented immunomediated polyarthritis, possibly associated to both the poisoning and later diagnosed hemoparasitosis (both Erlichia and Babesia). Discussion: Massive bee attacks can cause severe complications, however, data regarding emergency care records are scarce. Based on clinical signs and laboratory findings, the patient presented toxic systemic reaction, including grade II of acute kidney injury and significant cardiorespiratory distress. Another important complication was tongue necrosis, that demanded attention and special supportive care, including feeding tube and specific feed. Treatment also focused in reducing edema and control possible anaphylaxis, providing analgesia and antibiotic therapy. Laboratory findings have been previously described, with evidence of immune-mediated reaction. Follow-up consultations revealed normal parameters, and an unusual presentation of claudication. Investigation concluded that polyarthritis could be responsible for such finding and may be a result of the deposition of immunomediated complexes in the joints, due in this case to the bee poisoning and later positive diagnosis for both Erlichia and Babesia. Systemic reactions to bee stings are complex, and full clinical and laboratory profile aid in both the prognosis and treatment options. Special attention must be given to tongue damage and supportive care is essential for maintaining feeding conditions. Arthritis should be considered as possible complication, reinforcing the importance of follow-up consultations.

Coloboma eyelid in cats - treatment with carbon dioxide cryosurgery

Background: Eyelid colobomas are congenital and developmental disorders. Generally, they affect the temporal portion of the upper eyelids of cats, bilaterally. This ocular defect is accompanied by trichiasis associated with pain and ulcerative keratitis. Any breed can be affected and it has been reported in Domestic Shorthair, Persian, Burmese, Mongrel cats and captive felids. The objective of this case report is to describe the technique of dioxide carbon cryosurgery for the treatment of eyelid coloboma in felines. Cases: Seven mongrel cats (14 eyes) with bilateral eyelid coloboma were included in this study, 5 females and 2 males, with a median age of 5 months (range 6-8 months). The patients presented with blepharospasm, bilateral mucopurulent ocular discharge and eyelid coloboma extension of 30-50% in the upper eyelid, resulting in severe trichiasis of both eyes. In 5 cats, 1 or both eyes were diagnosed with keratitis and superficial corneal ulcers. Surgical treatment with general anaesthesia was applied. The pre anaesthesia protocol included acepromazine 0.05 mg/kg with methadone 0.2 mg/kg, followed by intravenous propofol and maintenance with isoflurane and oxygen. An ophthalmological cryocautery unit was utilised with carbon dioxide as the cryogenic agent and a retinal cryoprobe of 3.2 mm diameter tip, reaching -50ºC for the procedure. The method used was a double cycle of freezing and thawing for 60 s in the margins of eyelid agenesis. Epilation of hairs was made after freezing with eyelash tweezers. Immediately after the surgical procedure, an Elizabethan collar was placed to safeguard the area and anti-inflammatory therapy with meloxicam 0.1 mg/kg once daily for 3 days was prescribed. Antibiotic ointment every 6 h (chloramphenicol and associations) was also prescribed for topical application. Two weeks post-operatively, hyperaemia, oedema and skin wounds at the margins were observed. After 30 days these clinical signs were minimal. No signs of pain were observed post-operatively. The follow-up was 90 days and the trichiasis was resolved in all cats. Discussion: Usually, young cats are affected with eyelid colobomas. The age of the patients in this study was between 6-8 months. Eyelid colobomas are repaired with a variety of blepharoplastic procedures and the choice depends on the size and position of the defect. Generally, larger defects require more extensive reconstructive procedures. All techniques can have post-operative complications. Suture dehiscence, skin flap necrosis and facial deformation can occur with traditional surgical techniques. Furthermore, posterior hair growth in the margins can lead to new trichiasis. Cryosurgery was chosen and performed as the temperature of -20°C is sufficient to destroy hair follicles, without surgical incisions, avoiding scar formation. Hence, sutures are not necessary in cryosurgery procedures. Carbon dioxide is a good cryogenic agent for the purpose of this procedure. In the cases described, no recurrence of hair growth was observed in the follow-up period of 90 days. Nevertheless, a good aesthetic appearance was maintained. Therefore, the use of carbon dioxide cryosurgery is an effective and safe alternative for treatment of eyelid coloboma in cats. To our knowledge, no paper has described the use of carbon dioxide cryosurgery for the correction of palpebral agenesis in felines and other species as a single treatment. This technique is easy to perform, has good aesthetic and functional results and can be considered a treatment option for this congenital condition.

The need for opioid in the postoperative analgesia of dogs undergoing hemilaminectomy due to intervertebral disc extrusion

ABSTRACT: The aim of this study was to evaluate the postoperative analgesic effect of protocols with and without the opioid methadone in dogs with intervertebral disc extrusion undergoing decompressive surgery. Sixteen paraplegic dogs with preserved nociception underwent hemilaminectomy/disc fenestration and were randomly assigned to two groups. The analgesic protocol consisted of methadone, meloxicam and dipyrone in Group I (G1), and meloxicam and dipyrone in Group II (G2). The animals were blindly assessed by two observers, using the visual analogue scale (VAS) and the short-form Glasgow Composite Measure Pain Scale (CMPS-SF). Assessments occurred every 2 hours during first 24 hours post-surgery, and every 4 hours afterwards. There was no statistical difference among groups regarding pain scores or analgesic rescues. Both analgesic protocols provided analgesia in the initial 48 hours postoperatively, demonstrating that opioids are not necessary in the postoperative period of dogs undergoing hemilaminectomy and disc fenestration.

RESUMO: O objetivo deste estudo foi avaliar a analgesia pós-operatória de protocolos com e sem o opioide metadona em cães com extrusão de disco intervertebral submetidos à descompressão cirúrgica. Dezesseis cães paraplégicos com presença de nocicepção foram submetidos à hemilaminectomia/fenestração de disco e distribuídos aleatoriamente em dois grupos. No Grupo I (G1), o protocolo analgésico consistiu em metadona, meloxicam e dipirona e, no Grupo II (G2), por meloxicam e dipirona. Os pacientes foram avaliados de maneira cega por dois avaliadores, com base na escala visual analógica (EVA) e na escala simplificada composta de dor de Glasgow (CMPS-SF). As avaliações ocorreram a cada 2 horas durante as primeiras 24 horas de pós-operatório e, por mais 24 horas, a cada 4 horas. Não houve diferença estatística entre os grupos avaliados em relação à escores de dor e nem a necessidade de resgate analgésico. Ambos os protocolos promoveram analgesia nas 48 horas iniciais de pós-operatório, demonstrando não haver a necessidade do uso de opioide em cães submetidos à hemilaminectomia e fenestração de disco.

Effects of flunixin meglumine, meloxicam, and firocoxib on the acute-phase proteins in horses following standing castration

ABSTRACT: Excessive infection and inflammation are the most common complications associated with castration. The objective of this study was to compare the efficacy of flunixin meglumine (FM), meloxicam (MX), or firocoxib (FX) for inflammation control after castration in horses using acute-phase proteins (APP) as markers of inflammation. Thirty healthy, unbroken, mixed-breed horses (body weight 358.62±45.57kg and age 4.99±2.63 years) were randomly (n=10 animals/group) allocated to receive one of three different post-castration anti-inflammatory medicines: Group 1 (FM 1.1mg/kg bwt, IV, s.i.d for 5 days); Group 2 (MX 0.6mg/kg bwt, IV, s.i.d for 5 days); and Group 3 (FX 0.1mg/kg bwt, IV, s.i.d for 5 days). All horses were castrated in standing position, using the open technique. Serum and peritoneal APP concentrations were measured by sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis (PAGE) and determined before castration (0), and 3, 5, 24, 48, 72, 120 and 168 hours after castration. The results were submitted to analysis of variance using the SAS statistical program, and means were compared by the Student-Newman-Keuls test (p 0.05). Three animals from the MX group developed hyperthermia (with rectal temperatures of 39.8, 39.3 and 38.9°C on day 4, 5 and 6, respectively) and showed local clinical signs of inflammation (inguinal and excessive scrotal edema) and reluctance to walk, as well as a rigid gait of the hind limbs. The same complications were observed in one FX horse. No complications were observed among the FM animals. The castration resulted in significant changes in serum and peritoneal values of total proteins, ceruloplasmin (Cp), transferrin (Tf), albumin (Alb), haptoglobin (Hp) and 1-acid glycoprotein (Gp) in animals of all experimental groups. However, the animals of the MX and FX groups presented more intense acute phase response compared to the animals of the FM group. Changes in the APP were associated with the surgical trauma of castration, but the differences between groups were associated with the ability of the nonsteroidal anti-inflammatory drug to control the inflammation. In conclusion, and based on the findings of acute phase proteins, flunixin is more efficient to control the magnitude of inflammation following castration as compared to meloxicam and firocoxib.

RESUMO: Infecção e inflamação excessivas são as complicações mais comuns associadas à castração. O objetivo deste estudo foi comparar a eficácia do flunixin meglumine (FM), meloxicam (MX) ou firocoxib (FX) no controle da inflamação após a castração em cavalos usando proteínas da fase aguda (APP) como marcadores de inflamação. Trinta equinos saudáveis (358,62±45,57kg; 4,99±2,63 anos) foram em função dos anti-inflamatórios utilizados após as castrações aleatoriamente (n= 10 animais/grupo) alocados em três diferentes grupos: Grupo 1 (FM 1,1mg/kg de peso, IV, sid por 5 dias); Grupo 2 (MX 0,6mg/kg de peso, IV, s.i.d por 5 dias); e Grupo 3 (FX 0,1mg/kg de peso, IV, s.i.d por 5 dias). Todos os cavalos foram castrados em posição quadrupedal, utilizando a técnica aberta. As concentrações de APP sérica e peritoneal foram separadas por eletroforese em gel de poliacrilamida (PAGE) com dodecil-sulfato de sódio (SDS) e determinadas no momento 0 (antes da castração) e com 3, 5, 24, 48, 72, 120 e 168 horas após a castração. Os resultados foram submetidos à análise de variância pelo programa estatístico SAS e as médias foram comparadas pelo teste de Student-Newman-Keuls (p 0,05). Três animais do grupo MX desenvolveram hipertermia (com temperatura retal de 39,8, 39,3 e 38,9° C nos dias 4, 5 e 6, respectivamente) e mostraram sinais clínicos locais de inflamação (edema inguinal e escrotal excessivo) e relutância em andar, bem como marcha rígida dos membros posteriores. As mesmas complicações foram observadas em um cavalo do FX. Não foram observadas complicações entre os animais do FM. Independente do grupo, a castração resultou em alterações significativas nos valores séricos e peritoneais de proteínas totais, ceruloplasmina (Cp), transferrina (Tf), albumina (Alb), haptoglobina (Hp) e glicoproteína ácida 1 (Gp). No entanto, os animais dos grupos MX e FX apresentaram resposta de fase aguda mais intensa quando comparados aos animais do FM. Alterações na resposta de fase aguda deveram-se ao trauma cirúrgico da castração, mas as diferenças entre os grupos foram associadas à capacidade do anti-inflamatório em controlar a inflamação. Em conclusão, baseado da resposta de fase aguda, o flunixin em comparação com o meloxicam e o firocoxib é mais eficiente no controle da inflamação após a castração em equinos.

Excessive infection and inflammation are the most common complications associated with castration. The objective of this study was to compare the efficacy of flunixin meglumine (FM), meloxicam (MX), or firocoxib (FX) for inflammation control after castration in horses using acute-phase proteins (APP) as markers of inflammation. Thirty healthy, unbroken, mixed-breed horses (body weight 358.62±45.57kg and age 4.99±2.63 years) were randomly (n=10 animals/group) allocated to receive one of three different post-castration anti-inflammatory medicines: Group 1 (FM 1.1mg/kg bwt, IV, s.i.d for 5 days); Group 2 (MX 0.6mg/kg bwt, IV, s.i.d for 5 days); and Group 3 (FX 0.1mg/kg bwt, IV, s.i.d for 5 days). All horses were castrated in standing position, using the open technique. Serum and peritoneal APP concentrations were measured by sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis (PAGE) and determined before castration (0), and 3, 5, 24, 48, 72, 120 and 168 hours after castration. The results were submitted to analysis of variance using the SAS statistical program, and means were compared by the Student-Newman-Keuls test (p<0.05).

The need for opioid in the postoperative analgesia of dogs undergoing hemilaminectomy due to intervertebral disc extrusion / A necessidade de opioide na analgesia pós-operatória de cães submetidos à hemilaminectomia devido à extrusão do disco intervertebral

The aim of this study was to evaluate the postoperative analgesic effect of protocols with and without the opioid methadone in dogs with intervertebral disc extrusion undergoing decompressive surgery. Sixteen paraplegic dogs with preserved nociception underwent hemilaminectomy/disc fenestration and were randomly assigned to two groups. The analgesic protocol consisted of methadone, meloxicam and dipyrone in Group I (G1), and meloxicam and dipyrone in Group II (G2). The animals were blindly assessed by two observers, using the visual analogue scale (VAS) and the short-form Glasgow Composite Measure Pain Scale (CMPS-SF). Assessments occurred every 2 hours during first 24 hours post-surgery, and every 4 hours afterwards. There was no statistical difference among groups regarding pain scores or analgesic rescues. Both analgesic protocols provided analgesia in the initial 48 hours postoperatively, demonstrating that opioids are not necessary in the postoperative period of dogs undergoing hemilaminectomy and disc fenestration.(AU)

O objetivo deste estudo foi avaliar a analgesia pós-operatória de protocolos com e sem o opioide metadona em cães com extrusão de disco intervertebral submetidos à descompressão cirúrgica. Dezesseis cães paraplégicos com presença de nocicepção foram submetidos à hemilaminectomia/fenestração de disco e distribuídos aleatoriamente em dois grupos. No Grupo I (G1), o protocolo analgésico consistiu em metadona, meloxicam e dipirona e, no Grupo II (G2), por meloxicam e dipirona. Os pacientes foram avaliados de maneira cega por dois avaliadores, com base na escala visual analógica (EVA) e na escala simplificada composta de dor de Glasgow (CMPS-SF). As avaliações ocorreram a cada 2 horas durante as primeiras 24 horas de pós-operatório e, por mais 24 horas, a cada 4 horas. Não houve diferença estatística entre os grupos avaliados em relação à escores de dor e nem a necessidade de resgate analgésico. Ambos os protocolos promoveram analgesia nas 48 horas iniciais de pós-operatório, demonstrando não haver a necessidade do uso de opioide em cães submetidos à hemilaminectomia e fenestração de disco.(AU)

Postoperative analgesic effects of Reiki therapy in bitches undergoing ovariohysterectomy / Efeito analgésico pós-operatório da terapia Reiki em cadelas submetidas a ovariohisterectomia

ABSTRACT: This study aimed to evaluate the effects of Reiki therapy on postoperative pain in bitches undergoing elective minimally invasive ovariohysterectomy (OVH). Thirty bitches were randomly assigned to three groups: Control, Placebo, or Reiki. All dogs received methadone as preanesthetic medication (PAM), meloxicam in the preoperative period, propofol for anesthetic induction, and isoflurane for anesthetic maintenance. Immediately after OVH, the dogs in the Reiki were submitted to a single session of Reiki therapy, dogs in the Placebo received simulated Reiki therapy from a non-therapist, and dogs in the Control received no treatment. All dogs were evaluated for pain using short-form Glasgow composite measure pain scale (CMPS-SF) and visual analog scale (VAS) before (M0) and 2 (M2), 4 (M4), 8 (M8), 12 (M12), and 24 hours (M24) after administration of PAM. Comparing the CMPS-SF scores between the groups, at M2 Reiki scores were lower than those of the Placebo and at M4 those in the Reiki were lower than those of the Control or Placebo groups. Comparing the VAS scores, at M4 and M8, Reiki scores were lower than those of the Control or Placebo groups. Additional analgesia (morphine 0.2 mg.kg-1 intramuscularly) was administered to three bitches in Control and to four bitches of the Placebo. Reiki did not require additional opioid analgesia in the postoperative period. It was concluded that Reiki therapy provided analgesic effect and contributed to improve postoperative comfort of bitches submitted to elective OVH.

RESUMO: Este estudo teve o objetivo de avaliar os efeitos da terapia Reiki na dor do período pós-operatório de cadelas submetidas à ovariohisterectomia (OVH) eletiva pelo método minimamente invasivo com gancho. Para isso, foram utilizadas 30 cadelas alocadas aleatoriamente em três grupos experimentais: Controle, Placebo e Reiki. Todos os animais receberam metadona como medicação pré-anestésica (MPA), meloxicam, propofol na indução anestésica e isofluorano na manutenção anestésica. Imediatamente após a OVH, os animais do Reiki foram submetidos a uma única sessão de Reiki, os animais do Placebo receberam uma simulação da terapia Reiki por um indivíduo não terapeuta e os animais do Controle não receberam nenhum tratamento. Os animais foram avaliados por meio da forma curta da escala de dor de Glasgow (CMPS-SF) e da escala visual analógica (EVA) antes da administração da MPA (M0) e 2h (M2), 4h (M4), 8h (M8), 12h (M12) e 24h (M24) após a MPA. Comparando-se os valores obtidos pela CMPS-SF, em M2, os valores do Reiki foram menores que do Placebo e, em M4, os valores do Reiki foram menores que do Controle e do Placebo. Observando-se os dados obtidos com a EVA, em M4 e M8, os valores do Reiki foram menores que do Controle e do Placebo. Foi administrada analgesia adicional (0,2 mg.kg-1 de morfina por via intramuscular) em três animais do Controle e em quatro animais do Placebo. Os animais do Reiki não necessitaram de analgesia adicional no período pós-operatório. Concluiu-se que a terapia Reiki contribuiu com a analgesia e o conforto pós-operatório de cadelas submetidas à OVH eletiva.

Mammary fibroepithelial hyperplasia in a male cat

Background: Feline mammary hyperplasia (FMH) is a benign disease that commonly affects young females, once it iscaused by the exaggerated stimulation of endogenous or exogenous progestogen. FMH leads to acute edema and inflammation of the mammary glands and frequently evolve to ulcerations, secondary infections, and systemic clinical signs.Even though it is rare in male cats, progesterone therapy or an unknown endogenous source of hormone can cause thedisease. This report aims to describe a case of FMH in a male feline with no history of hormonal treatment and treatedwith radical surgical resection.Case: A 7-month-old intact male domestic shorthair cat was presented due to acute onset of generalized mammary tumorswhich had progressed for 18 days. Tumors size had 5 cm large in diameter, symmetric, bilateral, and affected all mammaryglands. The tissue was firm, hyperemic, and ulcerated. FMH was initially suspected but with a differential diagnosis formammary adenocarcinoma. Except for pain on tumor palpation, there was no other clinical abnormality. Survey thoracicradiographs and abdominal ultrasound did not find signs of metastasis or hermaphroditism. Fine-needle aspirate biopsy andfurther cytological examination were inconclusive. Surgical resection through a single-stage bilateral total mastectomy andreconstruction using a left flank fold flap was elected. There were no intraoperative complications and the cat recoveredwell, with good healing and no clinical signs 21 days after the surgery. Histological examination of the mammary glandsconfirmed the diagnosis of FMH due to the non-neoplastic characteristics and tissue’s benign biological behavior. Elevenmonths after diagnosis, the cat was asymptomatic.Discussion: The FMH frequently affects young females and is associated with gestational periods, the end of the estrouscycle, and, most commonly, hormonal therapy with synthetic progesterone. Male cats are rarely affected with or...
