Use of ozonized sunflower oil in the treatment of skin injury in golden hamster (Mesocricetus auratus): case report / Uso de óleo de girassol ozonizado no tratamento de lesão cutânea em hamster sírio (Mesocricetus auratus): relato de caso

Hamster breeding is becoming increasingly popular, mainly because of the simplicity of breeding, low cost, and characteristics of these animals: they are small, quiet, and do not require a large space. Because of this ease of keeping, some people choose to keep more than one animal of the same species in a single enclosure. In some cases, this sociability can lead to fights, because hamsters are extremely territorial animals, which can cause significant injuries. Knowledge of the most efficient methods for wound healing is essential in medicine for wild and exotic animals, as it allows faster clinical treatment and thus, stress reduction. The present case report refers to the therapeutic treatment of an extensive skin lesion in a golden hamster (Mesocricetus auratus) using ozonized sunflower oil. The treatment, which lasted 23 days, allowed complete healing of the lesion.

A criação de hamsters tem se tornado cada vez mais popular, especialmente pela facilidade de criação, pelo baixo custo e pelas características desses animais: são pequenos, silenciosos, e não necessitam de um grande espaço. Por essa facilidade de manejo, algumas pessoas decidem manter mais de um animal da mesma espécie em um único recinto. Em alguns casos, esse convívio pode causar brigas, visto que hamsters são animais extremamente territorialistas, podendo resultar em injúrias cutâneas significativas. O conhecimento sobre os métodos mais eficientes para a cicatrização de lesões é fundamental na medicina de animais silvestres e exóticos, possibilitando um manejo clínico mais rápido, consequentemente, redução do estresse. O presente relato refere-se ao manejo terapêutico de uma extensa lesão cutânea em um hamster sírio (Mesocricetus auratus) com o uso do óleo de girassol ozonizado. O tratamento, que teve 23 dias de duração, possibilitou a cicatrização total da lesão.

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.

Ruptura bilateral do músculo fibular terceiro em bovino / Bilateral rupture of the peroneus tertius muscle in bovine

Background: The peroneus tertius muscle is responsible for tarsal flexion and coordinate extension of the stifle joint. The most common causes of rupture are excessive effort when trying to rise on a slippery surface, mounting, or being mounted. Rupture of the peroneus tertius muscle is characterized by an inability to flex the hock. Most cases are not curable, presenting an unfavorable to poor prognosis, and the animal has to be euthanized. This study aimed to report the clinical picture and treatment of a bilateral rupture of the peroneus tertius muscle in a cow from the municipality of Castanhal, state of Pará (Amazonian biome). Case: We report the clinical picture and treatment of a bilateral rupture of the peroneus tertius muscle in a 4-year-old cow, mixed breed, weighing approximately 400 kg, calved 3 months ago, belonging to a batch of 40 cattle kept on extensive breeding system in a pasture of Urochloa (Brachiaria) brizantha. The clinical signs appeared after the cow was mounted by a 1,100 kg bull and consisted of lameness, falling into sternal decubitus with hind limbs extended backward, hyperextension of the hocks with flexed stifle, with the tibia and metatarsus in a straight line, which lead to a 90-degree position of the femur and knee. Abrasions in the dorsal region of the fetlocks reinforce evidence of dragging hooves. Diagnosis of bilateral rupture of the peroneus tertius muscle was performed by a clinical examination and semiological test. Nonsteroidal anti-inflammatory drugs (flunixin meglumine, 2,2 mg/kg, every 24 h for 4 days) were prescribed for treatment, in addition to resting in a paddock with good availability of pasture, water, and mineral salt. After 3 months, we observed an improvement of the clinical signs, and after 6 months, an almost complete recovery. Only a slight difficulty in flexing the hock when moving remained. Discussion: In the present report, bull mounting was the probable cause of the hyperextension of both hocks and the bilateral rupture of the peroneus tertius muscle. According to the handler, these clinical signs were only evidenced after the animal was mounted. As stated in the literature, accidents such as falls, slips, mounting or being mounted, as well as excessive traction and over-elevation of the limb are considered predisposing factors for the onset of the disease. Rupture of the peroneus tertius muscle is unusual in production animals; therefore, the low occurrence of reports on this kind of rupture in the literature makes this case even more unique. The bilateral injury differs from cases described in the literature, in which the reported injuries were always unilateral. Our findings reinforce the hypothesis that the act of mounting was the triggering factor for the bilateral rupture of the animal peroneus tertius muscle. The breeding system also differs from the cases diagnosed by the same authors, since they describe the disease in bovines kept on intensive or semi-intensive breeding. In the present case, the cattle were kept on an extensive breeding system. The extension and flexion tests used in the clinical examination allowed for the diagnosis of rupture of the peroneus tertius muscle in both limbs, similarly to what has been reported by other authors. Anamnesis, clinical findings, and exclusion of different diagnoses were decisive for establishing the diagnosis. The treatment chosen was efficient, even though the case was severe, as the injury occurred in both hind limbs.

Cerebral infarction and thrombotic meningoencephalitis in a calf due to candidiasis / Infarto cerebral e meningoencefalite trombótica em um bezerro devido a candidíase

We described a case of cerebral infarction and thrombotic meningoencephalitis due to candidiasis in a seven-month-old calf. The death occurred three days after the onset of apathy, fever, and the head's lateral deviation to the left. Macroscopic changes in the brain consisted of asymmetry of telencephalic hemispheres; the right hemisphere was enlarged, causing cerebellar herniation. A focally extensive red area was observed on the surface of the right occipital lobe. At cross-sections of the fixed brain, the lesions revealed to be extensive, red-brown, soft or cavitated areas affecting the white and grey matter from the level of the thalamus to the cerebellum and compressing subjacent structures. Histologically, there was acute, coalescent, multifocal necrosupurative meningoencephalitis, associated with vasculitis, congestion, thrombosis, edema, infarction, and intralesional fungal hyphae. The diagnosis of cerebral infarction and thrombotic meningoencephalitis due to candidiasis was made by the pathological changes, the staining and morphological characteristics of the agent, and immunohistochemistry. The cerebral infarction and thrombotic meningoencephalitis in cattle can result from vascular lesions due to infection by Candida sp.; although uncommon, this case demonstrated that candidiasis should be part of a list of differential diagnoses of severe brain injuries in cattle.

Descreve-se um caso de infarto cerebral e meningoencefalite trombótica devido a candidíase em um bezerro de sete meses de idade. A morte ocorreu três dias após o início de apatia, febre e desvio lateral da cabeça para a esquerda. As alterações macroscópicas no cérebro consistiam em assimetria dos hemisférios telencefálicos; o hemisfério direito estava aumentado, causando herniação cerebelar. Uma extensa área vermelha focal foi observada na superfície do lobo occipital direito. Nos cortes transversais do encéfalo fixado, as lesões revelaram áreas extensas, marrom-avermelhadas, moles ou cavitadas, afetando a substância branca e cinzenta desde o nível do tálamo até o cerebelo e comprimindo as estruturas subjacentes. Histologicamente, havia meningoencefalite necrossupurativa multifocal aguda, coalescente, associada a vasculite, congestão, trombose, edema, infarto e hifas fúngicas intralesionais. O diagnóstico de infarto cerebral e meningoencefalite trombótica devido a candidíase foi feito pelas alterações patológicas, coloração e características morfológicas do agente e imuno-histoquímica. O infarto cerebral e meningoencefalite trombótica em bovinos pode resultar de lesões vasculares devido à infecção por Candida sp.; embora incomum, este caso demonstra que a candidíase deve fazer parte de uma lista de diagnósticos diferenciais de lesões cerebrais graves em bovinos.

Úlcera de córnea em bugio-ruivo (Alouatta guariba clamitans) - tratamento com soro heterólogo / Corneal ulcer in a Southern brown howler monkey (Alouatta guariba clamitans) - treatment with heterologous serum

Background: In the routine care of non-human primates, ocular trauma is frequent, however, unlike the small animal clinic, the prevalence of corneal ulcers is not documented. Among the numerous therapeutic options available in dogs, blood serum is being increasingly used as an adjuvant treatment in these conditions, due to its tear-like properties. Based on this, the present study aims to describe a case of corneal ulcer in a southern brown howler monkey (Alouatta guariba clamitans) attacked by a porcupine, and the use of heterologous serum obtained from an equine as an adjuvant treatment. Case: A southern brown howler monkey (Alouatta guariba clamitans), which had been attacked by porcupine quills, was treated at a University Veterinary Hospital. During the clinical examination, the presence of blepharospasm and secretion in the right eye was noticed. The ophthalmological examination, through the fluorescein test, detected the presence of an extensive superficial corneal ulcer in the right eye. After removing the spines, the corneal ulcer was treated with tobramycin-based eye drops, 1% atropine sulfate eye drops, and serum from equine blood in the form of eye drops, as an adjuvant therapy. After 5 days of treatment, the fluorescein test was repeated, which was negative in both eyes due to complete healing of the lesion, and thus the treatment was concluded. Discussion: The scarcity of scientific literature on wild animals is one of the factors responsible for the difficulty in advancing clinical and surgical procedures in non-human primates. Corneal ulcers are characterized by the loss of corneal epithelium with exposure of the stroma. The main clinical treatments adopted include antimicrobial therapy, analgesics, lubricating agents, and antiprotease drugs. Widely used as an adjuvant therapy in corneal ulcers in small animals, blood serum presents some advantages, as it is rich in growth factors, vitamins, immunoglobulins, and anti-collagenolytic substances, in addition to being obtained for a low cost. Considering the aforementioned, in the case reported, it was decided to use blood serum obtained from an equine as an adjuvant treatment of the corneal ulcer in a southern brown howler monkey. Complete healing of the corneal ulcer was confirmed in just five days, contributing to the well-being of this animal and contributing to the evolution of ophthalmology in this species that is still poorly studied.

Tratamento de tromboembolismo e preparo para implantação de prótese osteointegrada com oxigenioterapia hiperbárica em uma gata / Treatment of tromboembolism and preparation for an osseointegrated prothesis fixation with hyperbaric oxygen therapy in a kitten

Background: Ischemic neuromyopathy is the most common reason for amputation in cats. In veterinary medicine, the use of prosthetic limbs is not widespread; therefore, in most cases total limb amputation is indicated. However, hyperbaric oxygen therapy (HBOT) is an alternative with several benefits for the treatment of vascular disorders with reperfusion, ischemia, and infection. Therefore, this study aimed to report the positive effects of HBOT on the treatment of ischemic neuromyopathy secondary to arterial thromboembolism on the patient's clinical improvement, and on the preparation of the patient for insertion of an osseointegrated prosthesis. Case: A 6-month-old mixed-breed kitten returned for treatment after undergoing surgery seven days earlier for reduction of traumatic diaphragmatic hernia, during which it suffered a cardiorespiratory arrest. The patient presented with acute pelvic limb paralysis with 24-h evolution, absent femoral pulse, plantar cushions and dorsal part of the limbs cold and pale. After supportive therapy and diagnosis of aortic thromboembolism by arterial Doppler, the patient started adjunctive treatment with HBOT from the first day of hospitalization. Sessions took place in an exclusive hyperbaric chamber for animals and lasted 60 min at a pressure of 2.5 absolute atmospheres and 100% oxygen, initially every 12 h. However, during the first 5 days of hospitalization, the distal region of both pelvic limbs began to show tissue devitalization and edema, and hematologic parameters showed changes on the 7th day. The right pelvic limb (RPL) showed more involvement of superficial tissues, extending to the tarsometatarsal joint region. After 8 days of hospitalization, the devitalized tissue was debrided. The RPL had an extensive devitalized area with exposed bone in the phalanges and necrosis in the pads. The left pelvic limb (LPL) suffered minor complications, with involvement of the phalangeal region. After 12 days, with HBOT every 48 h, exuberant granulation tissue was observed. After 17 days, the patient was discharged, and HBOT sessions were performed weekly. Gangrene of the midfoot and lack of proprioception were observed in RPL, while LPL showed bone divulsion of the 1st, 3rd, and 4th phalanges. Because of the poor prognosis for limb viability, the RPL was partially amputated, and a self-threaded intraosseous prosthesis was inserted. Discussion: The cardiorespiratory arrest that occurred during the surgical procedure to reduce the diaphragmatic hernia without thromboprophylaxis may have contributed to the peripheral ischemia. HBOT was proposed for the adjuvant treatment of ischemic injury because it is especially indicated for cases of ischemia-reperfusion injury. The main hematological parameters were evaluated at an average interval of 7 days. While the platelet count and hematocrit increased, the leukocytosis decreased. This demonstrates the benefit of oxygen therapy in the reported patient. The use of HBOT in orthopedic injuries is known to result mainly in stimulation of osteoblasts, promoting osseointegration of the prosthesis. We conclude that the adjuvant treatment with HBOT helped to preserve a large segment of both pelvic limbs, prevent the progression of necrosis, and provide a healthy bed for fixation of an osseointegrated prosthesis in the RPL, resulting in clinical improvement of the patient.

Eletrocussão em Preguiça-real (Choloepus didactylus) - abordagem clínica e cirúrgica / Electrocution in a sloth (Choloepus didactylus) - clinical and surgical approach

Background: High voltage electric shock causes serious injury to the body, which can lead to a fatal condition. Sloths are commonly the target of this type of accident and factors such as the degree of tissue impairment and late medical care can contribute to the death of the animal or the indication of euthanasia. In this way, the present study aims to describe the treatment strategies in Choloepus didactylus victim of high voltage electrocution. Case: A female sloth weighing 6.15 kg was treated at the Wild Animals Sector of the Veterinary Hospital (HV-SAS) of the Federal University of Pará (UFPA) victim of high voltage electric shock with burn on the right side face, stomatitis, glossitis, lesions extensive and bullous lesions in the thoracic and pelvic limbs, in addition to an open fracture in the radioulnar joint of the left limb with signs of necrosis. After patient stabilization (fluid therapy, antibiotic therapy, pain control, cleaning and wound dressing), the patient was transfered to the impatient room. The main treatment strategies adopted were surgery, drug therapy, food and occupational therapy. The day after the patient's arrival, the amputation of the left thoracic limb was performed. On the third day of hospitalization, the right thoracic and pelvic limbs were also amputated, and on the tenth day, debridement of the right lateral face was performed. As for drug therapy, the following drugs were used postoperatively: ceftriaxone (40 mg/kg, BID, for 47 days), dexamethasone (0.5 mg/kg, BID, for 4 days), silymarin (15 mg/kg, BID, for 30 days), morphine (0.4 mg/kg, BID, for 14 days; 0.8 mg/kg, SID, for 22 days) and dressing wounds on the lateral face and surgical stumps with ointment of collagenase with chloramphenicol. In food management, the animal had good acceptance of a mixture of fruits, vegetables and animal protein in a pasty presentation. The treatment by occupational therapy included basic care such as exercising, sunbathing, and desensitizing the surgical stumps (massage therapy). In conclusion, after five months, the therapeutic protocol implemented resulted in the clinical improvement of the animal, as it allowed the complete healing of the lesions on the face and surgical stumps. In addition, the care taken with the surgical stumps allowed the animal to use them as support for its locomotion. Discussion: Amputation and debridement surgeries were effective in treating electrocuted patients and should be considered when tissue is compromised, which justifies the surgical protocol adopted in this study. They were based on reports in humans, since in wild animals, although many are victims of this type of trauma, little is known about the appropriate therapeutic approach for each species. Surgical interventions associated with the antibiotic ceftriaxone were efficient for controlling the infection, since this antibiotic has a broad spectrum of activity, being used mainly in skin and soft tissue and/or bone infections, which justified its use in that patient. As for nutritional therapy, supplementation with animal protein may have contributed to the clinical improvement of the animal, since they are excellent components for tissue recovery in patients who suffered losses from burns caused by electric shocks. Stump desensitization is indicated as a treatment for neuropathic pain in amputees, and in the present study, it was essential for the animal to use the limb for locomotion. The exercises in a grassy area associated with sunbathing added as a stimulus to the patient's movement.

Reconstrução prepucial com uso de enxerto combinado em cães / Preputial reconstruction combined with graft in dogs

Background: Preputial injuries are significant in the clinical routine. Traumas, conditions, and mass excision result in extensive and full-thickness defects that lead to chronic penile exposure and consequential injuries. Severe injuries may require preputial reconstructive surgery to restore function and aesthetics. The objective is to report the use of the preputial reconstruction technique using the caudal superficial epigastric axial standard flap associated with a single-stage, full-thickness oral mucosa graft in 3 dogs where the loss of the prepuce was significant. Cases: Three dogs were admitted to the Veterinary Teaching Hospital of UFMT with preputial lesions of different etiologies. All cases were referred for preventive reconstruction using a flap in the caudal axial epigastric pattern associated with a single-stage oral mucosa graft. In the 3 reported cases, changes that compromised surgical success, such as suture dehiscence, necrosis, or infection, were not observed during hospitalization. Cutaneous stitch dehiscence, however, was observed in all 3 cases. Dog 1. A small point of dehiscence and tissue necrosis was found and treated with chemical debridement and healed by second intention, which proved to be sufficient on the 30th day. Dog 2. A half-moon rotation flap was performed, which closed the defect. Dog 3. A new procedure using the reporting theme technique was necessary in order to cover the cranial portion of the foreskin. The dehiscence present in dogs 2 and 3 was significant. Flap retraction was observed in all 3 cases. In dogs 1 and 3, the retraction was slight, and the exposure of a small portion of the penile glans were observed, showing no changes that required intervention. In dog 2, retraction was important, leading to partial stenosis of the preputial ostium. A larger ostium was obtained by suturing the mucosa to the edge of the wedge. Considering the possibility of adhesion formation, "captons" were made in sterile silicone tubes, and sutures were placed in the dorsal and ventral aspects to prevent adherence of the oral mucosa graft located on the inside of the new foreskin. The captons were removed on the tenth post-operative day, revealing a good opening of the preputial orifice and adequate penile exposure. Discussion: The absence of a foreskin caused by trauma or surgical excision leads to chronic penile exposure, dryness, and ulcerations. The simple covering of the skin with an axial-type flap of the caudal superficial epigastric region tends to fail since only the graft edges are sutured into the abdominal skin. In these circumstances, the subcutaneous region on the penis is exposed and comes in direct contact with urine and the penile mucosa, causing the flap skin to grow to exacerbated retraction. The transplantation of a free-lip mucosa graft allows the subcutaneous region of the transposed skin flap to create adhesions in the fenestrated regions of the lip tissue through the formation of granulation tissue buds, which is performed in a single stage. The permanence of the penis protects the lower urinary system from the occurrence of infections relative to what is normally observed in cases where partial or total penile amputation is practiced in combination with adjunctive scrotal urethrostomy. Given the observations of the 3 cases described here, the technique of pre-facial reconstruction with an axial skin flap of the caudal superficial epigastric region, combined with free-labial mucosa graft, was found to be feasible for the single-stage foreskin technique, but that paraphimosis remanagement may be necessary when cutaneous portions of the penile skin caudal to the glans are removed.

Penile fractures in young bulls raised in feedlots in Southern Brazil

Background: Penile fracture is a pathology of young cattle that perform precocious and disordered breeding. The incompatibility of height between males and females and sodomy between males cause a great pressure on the sigmoid flexure and retractor muscle of the penis, which are the main causes and sites of organ injury. This study aimed to describe the epidemiological and pathological aspects of penile fractures observed in young bulls raised in pre-export feedlots (PEFs) in southern Brazil. Cases: In 2 PEFs located in the municipalities of Pelotas (property 1) and Capão do Leão (property 2), 3 male cattle [1 from property 1 and 2 from property 2] presented subcutaneous edema in the foreskin and perineum, associated with dysuria. The evolution of the clinical picture was approximately 20 days in all cases, with evolution to death. The bovine necropsied on property 1 had an increased volume and inguinal edema, involving the penis and scrotal sac. Necrosis of the subcutaneous tissue and local musculature was also observed. The testicles were surrounded by the necrotic tissue, and the right testis was swollen, with flaccid parenchyma adhering to the tunica albuginea. In the necropsy of 1 bull from property 2, an increase in the inguinal volume was observed, with an extensive area of necrosis and edema extending from the prepuce to the caudal musculature of the scrotal sac. There were also marked varicosis in the sigmoid flexure and necrosis of the adjacent region, without the involvement of the corpus cavernosum. During the necropsy of the 2 young bulls, fragments of organs from the abdominal, thoracic, and brain cavities were collected and fixed in 10% buffered formalin. From the bull of the property 2, an anatomical piece consisting of the penis, prepuce, and testicles was also collected and fixed in 10% buffered formalin. After 48 h, the tissue samples were cleaved, embedded in paraffin, cut into 3-µm-thick sections, and stained using hematoxylin and eosin (HE). A histological evaluation of the penile lesions in both cattle revealed intense hemorrhage, congestion, and necrosis of the muscles and tissues adjacent to the corpus cavernosum. In addition to areas of dystrophic calcification, neutrophil and macrophage infiltration was also observed. In the bull from the property 1, an intense edema and proliferation of fibrous tissue surrounding the urethra were noted. There were also marked tubular degeneration and intense infiltration of neutrophils, lymphocytes, and macrophages in the inner portion of the tunica albuginea. Discussion: In the present cases, the diagnosis was based on epidemiological data associated with clinical signs and pathology. The macroscopic lesions observed were probably due to the involvement of blood vessels adjacent to the penis, which suffered trauma during sodomy mating among cattle. These lesions have been described in other reports of this pathology and in diseases, such as acropostitis-phimosis, fibropapilloma of the glans, preputial abscess, and urolithiasis, and the differential diagnosis of these diseases must be carried out, as they have different etiologies. In the bulls of the present study, no lesions were observed in the corpus cavernosum, and this condition was attributed to the presence of varicosis and accumulation of urine in the prepuce, due to the difficulty in exposing the penis. Histologically, there were intense hemorrhage, congestion, and necrosis of the muscles and tissues adjacent to the corpus cavernosum, with the infiltration of neutrophils and macrophages, and areas of dystrophic calcification. The presence of necrotic lesions in tissues adjacent to the penis may be related to hypoxia, vascular lesions, or the action of chemical elements present in the urine. In both cases, vascular lesions were present, which were attributed to the main triggering factor for the disease.

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.

Necrose tissular em equino associada ao uso de fenilbutazona / Tissue necrosis in equine associated with use of phenylbutazone

Background: Wounds that occur with tissue necrosis and that result from the application of medications through the most diverse accesses are described as drug skin medical embolism or Nicholas syndrome in human medicine, with wide description. In veterinary medicine, this subject has not yet been described extensively and specifically in veterinary medicine, especially regarding to wounds that occurred after the application of non-intravenous medications in horses, even though these lesions are recurrent in the clinical routine. This report aims to describe a case of skin necrosis in a horse, due to phenylbutazone infection. Case: A 7 year-old Mangalarga Marchador horse, weighing 400 kg, was admitted to the Veterinary Hospital for Large Animals of the Universiade Federal Rural do Rio de Janeiro (UFRRJ), with a history of phenylbutazone injection to the left side of the neck. The animal had an extensive wound on the neck and face on the left side and was characterized by the presence of cold and devitalized skin, with a hardened and parched appearance and that easily detached. During the anamnesis, a single administration of 10 mL of a non-steroidal anti-inflammatory drug based on phenylbutazone was reported intramuscularly for about 10 days to control the pain resulting from the claudication present for 14 days. The medication was administered in the region of the lateral border of the neck, on the left side. After drug administration, the animal presented an increase in volume at the application site. After 24 h, the lesion spread from the inoculation region, extending to the head and chest of the animal. During debridement, it was found that the lesion did not reach the underlying muscle tissue. In addition to the wound, the animal had upper eyelid palsy, lower lip, and auricular ptosis. Treatment with surgical debridement of devitalized tissue, topical application of ozonated sunflower oil, ketanserin, and a free skin graft was instituted. During hospitalization, the animal had a corneal ulcer in the left eye with an unfavorable prognosis due to paralysis of the upper eyelid, with enucleation of the affected eyeball. The animal was under veterinary care for 180 days and was discharged when his wound was already in an advanced stage of healing. Discussion: The history of the application of phenylbutazone intramuscularly and the location and characteristics of the lesion presented by the patient in the present report suggest that this animal presented aseptic tissue necrosis resulting from the administration of non-steroidal anti-inflammatory drugs, phenylbutazone. Although aseptic tissue necrosis, better known as Nicolau's syndrome or drug embolism cutis, is widely characterized and described in this species, there are studies in the literature that reproduce the syndrome in pigs and rabbits. Phenylbutazone was able to cause arterial damage, mainly in the tunica intima of the artery in which the medication was administered, with perivascular inflammatory infiltrate and subsequent skin necrosis at the site of administration. In addition to the skin lesion, the animal started to show signs compatible with the left facial nerve lesion, evidenced by the immobility of the upper eyelid and labial and ear ptosis. This resulted in corneal ulceration and subsequent enucleation. The animal also developed chewing difficulty in the first months of hospitalization. This dysfunction may be due to a lesion of the mandibular nerve, responsible for innervating the masticatory muscles and the oral mucosa. However, the animal showed improvement in this aspect, no longer showing this condition after 90 days of hospitalization. The treatment used was successful in healing the wound.

Fratura exposta do fêmur em preguiça-real (Choloepus didactylus) - tratamento e reabilitação / Open fracture of the femur in a two-toed sloth (Choloepus didactylus) - treatment and rehabilitation

Background: The Choloepus didactylus is characterized by having 2 fingers on the forelimbs and 3 on the hind limbs, being found more frequently in northern South America, in countries such as Venezuela, Guyana, Ecuador, Peru, and Brazil. In Brazil, deforestation of the Amazon rainforest has threatened the survival of C. didactylus. In addition, these animals can be affected by several diseases, being those of the musculoskeletal system with limited reports. Thus, the present report aimed to describe the treatment and evolution of an open fracture of the femur in a free-living Choloepus didactylus, which after rehabilitation was released back to the wild. Case: A free-living female two-toed sloth (Choloepus didactylus), weighing 7.0 kg, was found in Manaus city and referred to the Wild Animal Treatment Center (CETAS - IBAMA-AM) located in Amazonas, Brazil, after initial treatment and osteosynthesis in a private clinic (CVMinasPet). According to history, the animal had suffered electrocution 30 days ago and, as a result, had an extensive wound that resulted in the exposure of the knee joint, distal fracture of the femur, and areas of necrosis in the right pelvic limb. After cleansing of the area and removal of necrotic tissues, the fracture was stabilized with the cross-pinning technique (2 Steinmann pins). Then, the stifle joint was stabilized with external skeletal fixation (Type 1b, unilateral biplanar). The external fixator and cross-pins were removed 2 months after the surgical procedure, being observed bone healing. Next, the animal underwent physical rehabilitation for 30 days. After the rehabilitation period, a microchip and a radio collar were applied, and the sloth was released back to the wild. Discussion: Electrocution has been one of the causes of wildlife rescue, with consequences varying depending on the degree of the burn. Generally, the burn is most severe at the entry and exit sites. Since suspensory quadrupedal locomotion requires that sloths have specialized hands and feet to connect with the supports, probably the animal of the current report touched the right pelvic limb on a high-tension pole. The cross-pinning technique combined with the external fixator was used because the animal had an exposed Salter-Harris type I fracture with soft tissue loss. The younger the animal presents physeal fractures, the greater is the chance of developing growth abnormalities due to growth plate closure caused by fracture type or immobilization method. Since the sloth was a free-living animal, the age was unknown. However, pelvic limb length discrepancy was not observed after removing the implants. Culture and antimicrobial susceptibility test were not done and may be considered a limitation of this report. However, the application of ceftriaxone was adequate to control the infection, since the animal did not show signs of infection or draining sinus tracts. Ceftriaxone is a third-generation antibiotic that can be used in chronic osteomyelitis. In addition, the animal in the present report showed good adaptation to captive conditions that contributed to the clinical management. The longevity of the sloth in captivity can reach more than 30 years, but the goal is always to return the animal to nature after the treatment. Surgical treatment of the fracture and physical therapy after implant removal allowed this action in the current report, confirmed by monitoring with the radio collar.

Tubular subdermal flap to dorsal nasal reconstruction in a dolichocephalic dog: case report / Retalho tubular subdérmico para reconstrução dorsal nasal em cão dolicocefálico: relato de caso

This case report described the use of tubular subdermal flap to dorsal nasal reconstruction of an old dolichocephalic dog. A nine-year-old Dachshund female dog-weighing 10 kg presented with deep and extensive wound in the dorsal nasal region was attended at veterinary clinic, Sorocaba city, São Paulo, Brazil. The reconstructive surgical procedure was performed in three stages with an interval time of 25 days, which included the preparation of the tubular subdermal flap; the advance of the flap to the region of the tissue defect, and the removal of excess flap. The region healed 14 days after the last stage. The tubular subdermal flap was effective for treating ulcerative epithelial wounds associated with interstitial lymphoplasmocyte dermatitis and vasculitis of the dorsal nasal region of an old Dachshund dog.

Peritonitis and necrotizing hepatitis in Ara ararauna caused by a foreign body

Background: The ingestion of foreign bodies in parrots has already been described and associated with the curious behaviorof the birds or with stressful conditions. Foreign bodies in the gastrointestinal tract are usually diagnosed through clinicalsigns, laboratory tests, and radiographic findings in the historical data. Foreign bodies are usually metallic and can lodgein any segment of the gastrointestinal tract, commonly found in the proventricle and gizzard. This study investigated acase of necrotizing hepatitis due to a foreign body in Ara ararauna (Linnaeus, 1758).Case: An approximately 9-month-old specimen of caninde macaw, had sudden death and was referred for autopsy. Themacroscopic examination revealed a fibrous, thick, reddish membrane involving the left hepatic lobe and partially the gizzard in continuity with the peritoneum. Inside the capsule, the liver had a friable and necrotic appearance and the gizzardhad a focal perforation area containing a foreign body (gavage tube feeding). We performed the histopathological examination of the liver and gizzard and observed that the membrane surrounding the liver and partially the gizzard had a chronicinflammatory process with a marked proliferation of fibrous tissue and fibrin deposition. The hepatic parenchyma of theleft lobe showed diffuse and marked necrosis, with signs of ischemic necrosis. In the region of transmural perforation ofthe gizzard, the mucosa showed a focal area of extensive necrosis accompanied by the presence of intralesional bacteria.The lesions observed are attributed to the perforation of the organs by the foreign body. It is not known whether the birdingested the object accidently during food handling as a young or due to the curious behavior of the bird or even the stressit may have been exposed to. The post mortem examination revealed localized peritonitis...

Ocular and oral lesions caused by Tacinga inamoena in sheep and goats in Northeast Brazil / Lesões oculares e orais causadas por Tacinga inamoena em ovinos e caprinos no Nordeste brasileiro

Two outbreaks of traumatic injuries in goats and sheep associated with grazing and ingestion of the cactus Tacinga inamoena have recently been reported in the state of Paraíba, Brazil. In the first of these, which was detected in 2019 during a preliminary inspection of a herd of 70 animals, it was found that 15 showed certain ocular complications, and these animals were subjected to general physical and ophthalmic examinations. The clinical findings included excessive lacrimation, blepharitis, photophobia, corneal opacity, hyphema, corneal neovascularization, corneal ulcers, and adherence of gloquids to the bulbar conjunctiva and cornea. Large amounts of T. inamoena were found to be present in several areas in which these animals had been grazed and had been observed consuming the fruits of this plant. In the second outbreak during the following year, two sheep from a total of 100 animals were identified as having oral lesions associated with grazing in areas within which T. inamoena was growing. One of these animals was referred to a veterinary hospital, and on physical examination was found to show apathy, anorexia, a body score of 1.5, and the presence of gloquids within the fur. With respect to the oral cavity, halitosis, severe sialorrhea, extensive hemorrhagic ulcers, and painful tenderness on palpation were detected. Given the unfavorable prognosis, the sheep was subsequently euthanized. At necropsy, multifocal to coalescent plaques were detected on the upper and lower lips, oral mucosa, tongue, and hard and soft palates. These were generally elevated and firm and characterized by an irregular, ulcerated surface, sometimes crusty, with a yellow to light brown center and erythematous edges. The findings of this study highlight that the consumption of T. inamoena can cause serious oral and ophthalmic lesions in small ruminants in the northeastern semi-arid regions of Brazil, and can potentially contribute to substantial large economic losses. This problem tends to be exacerbated by the invasive behavior of T. Inamoena, particularly in areas in the process of environmental degradation.(AU)

Relatam-se dois surtos de lesões traumáticas associadas ao pastejo e ingestão da Tacinga inamoena por caprinos e ovinos no estado da Paraíba, Brasil. No primeiro surto observou-se durante uma inspeção preliminar do rebanho que 15 dos 70 animais apresentavam alterações oculares, os animais foram submetidos ao exame físico geral e ao exame oftálmico. Lacrimejamento excessivo, blefarite, fotofobia, opacidade de córnea, hifema, neovascularização corneana, úlceras de córnea e gloquídeos aderidos à conjuntiva bulbar e córnea foram os achados clínicos identificados. A planta estava presente em diversas áreas e em grande quantidade nas áreas de pastejo, onde os animais eram vistos ingerindo seus frutos. No segundo surto, dois ovinos de um total de 100 animais, foram identificados com lesões orais associadas ao pastejo em áreas da planta. Um deles foi encaminhado ao Hospital Veterinário. No exame físico, o animal apresentou apatia, anorexia, escore corporal 1,5, pelos opacos, eriçados e no pelame era possível identificar gloquídeos. Na cavidade oral observou-se halitose, sialorreia intensa, extensas úlceras hemorrágicas e sensibilidade dolorosa à palpação. Devido ao prognóstico desfavorável o animal foi eutanasiado. Na necropsia, placas multifocais a coalescentes, elevadas, firmes e com superfície irregular, ulcerada, por vezes crostosas, com centro amarelo a marrom-claro e bordos eritematosos, estavam presentes nos lábios superiores, inferiores, mucosa oral, língua, palatos duro e mole. T. inamoena causa sérias lesões orais e oftálmicas em pequenos ruminantes no semiárido nordestino e prejuízos econômicos de grandes dimensões, que podem ser agravados pelo comportamento invasor da T. inamoena em áreas com indícios de degradação ambiental.(AU)

Lesions caused by anisakid and capillariid in Cairina moschata raised on Marajó island, state of Pará, Brazil / [Lesões por anisakideos e capillariideos em Cairina moschata criados na Ilha de Marajó, estado do Pará, Brasil]

The Muscovy duck is a commercially important bird on the island of Marajó usually raised in a peculiar system that includes supplying fish viscera to the birds under semi-extensive farming conditions. This enables a risk of contamination and losses in the production of these birds, resulting from injuries caused by helminth infections, especially nematodes. The objective of this study was to evaluate the histopathological changes caused by nematodes of the genera: Eucoleus, Anisakis and Contracaecum. Thirty-three ducks with lesions in the esophagus and ventricle were analyzed. Histopathological exams showed a mild inflammatory infiltrate in the submucosa of the esophagus caused by the fixation of E. contortus and third stage larvae of Anisakis sp., and we recorded third stage larvae of Contracaecum sp. parasitizing the ventricle, this being the first record of this parasite in ducks in Brazil.(AU)

O pato doméstico é uma ave amplamente comercializada na Ilha de Marajó, com um peculiar manejo que inclui a oferta de vísceras de peixes aos animais em criações semiextensivas, propiciando, assim, risco de contaminação e perdas na produção dessas aves decorrentes de lesões oriundas de infecções por helmintos, especialmente os nematódeos. Nesse sentido, objetivou-se avaliar as alterações histopatológicas causadas por nematódeos dos gêneros: Eucoleus, Anisakis e Contracaecum. Foram analisados 33 patos, e três exemplares apresentaram lesões no esôfago e no ventrículo. Exames histopatológicos demonstraram discreto infiltrado inflamatório na submucosa do esôfago ocasionado pela fixação de E. contortus e larvas de terceiro estágio de Anisakis sp., bem como foram registradas larvas de terceiro estágio de Contracaecum sp. parasitando o ventrículo, sendo esse o primeiro registro desse parasito em patos no Brasil.(AU)

Utilização de hipoclorito de sódio 0, 5% no tratamento de ferida aberta em uma cadela – relato de caso / Use of 0, 5% sodium hypochlorite solution to treat cutaneous wound in dog – case report

Foi atendida em uma clínica veterinária na cidade de Maceió/AL uma cadela Poodle apresentando extensa área de ferimento cutâneo contaminado em face crânio-lateral do membro torácico direito. Procedeu-se a limpeza da lesão e instituiu-se protocolo de tratamento utilizando-se solução de hipoclorito de sódio 0,5%, através da dispersão para antissepsia e facilitação da retirada de crostas e debris necróticos. O tratamento foi conduzido durante vinte e quatro dias observando-se completa recuperação do animal. Neste trabalho discute-se a utilização do hipoclorito como método alternativo, eficiente, de baixo custo e de fácil aplicação para tratamento de feridas abertas.

A female Poodle dog showing an extensive area of a contaminated cutaneous wound on the cranio-lateral surface of the right arm was take care in a veterinary clinic on Maceio city. The injury was washed and then a clinical protocol of treatment was used with the buffering of a 0,5% Sodium Hypochlorite solution to promote antisepsis and improve the removal of necrotical debris and crusts. The treatment was conduced for twenty days and was observed the complete recover of the animal skin at the end of it. On this work the use of Hypochlorite can be considered an alternative treatment method for contaminated cutaneous wound by its efficient action, low costs and easy application.
