Clitoridectomy and urethrostomy in a pseudohermaphrodite dog

Background: Hermaphroditism is a rare congenital disease that causes ambiguous sexual features. True hermaphroditeshave testicular and ovarian tissue, whereas pseudohermaphrodites have only one type of gonadal tissue and genitalia, butsecondary characteristics of the opposite sex. Pseudohermaphrodites are classified as male or female according to theirgonads. Treatment of pseudohermaphroditism consists of surgical removal of the gonads including reconstruction of abnormal genitalia, especially if the urethra is involved. Therefore, the objective of this report is to describe a case of a malepseudohermaphrodite in a dog treated with clitoridectomy with urethrostomy.Case: A 7-month-old, mixed-breed dog was referred due to the presence of a flaccid structure similar to a small penis,containing an os clitoris, bulbourethral glands, and urethra protruding from the vulva. Physical examination, completeblood count and serum biochemistry were within normal ranges. Hormonal levels of estradiol, testosterone, and progesterone were 56.39 pg/mL, 127.9 ng/mL, and 0.892 ng/mL, respectively. The abdominal ultrasound and posteriorly theexploratory celiotomy found a normal size prostate and two round organs resembling testicles connected to a uterus-liketubular structure. The patient underwent surgical abdominal exploration that confirmed the ultrasonographic findings andled to gonadohysterectomy. Also, clitoridectomy and urethrostomy were performed to excise the protruded structure andmaintain normal urethral patency. The histopathological examination of the clitoris and penis confirmed it was a malegenital organ, however, the abdominal structures were compatible with the testicles, epididymis, uterus, and even a broadligament. These organs are normally found in cases of male pseudohermaphroditism. The...

Open surgical thrombectomy and coronary stent placement for treatment of aortic thrombotic disease in a bitch

Background: The thrombotic aortic disease in dogs and cats is characterized by the pathological formation of blood clots that can rupture and obstruct the blood flow. Abdominal ultrasonography can identify the location and extension of thrombus in the main vasculature and using the doppler it is possible to observe the blood flow around the thrombus. Stents are expandable tube-shaped endoprosthesis characterized as a metal mesh and used to prevent or repair stenoses, allowing liquid, gas, or solids to flow. This report aims to describe the surgical and medical treatment of aortic thrombotic disease followed by coronary stents placement in a bitch. Case: An 8-year-old Shih Tzu bitch, presented for evaluation of a 1-month progressive hind limbs paresis. Nociception was present in both limbs, but the patient presented discomfort and vocalization when manipulating the pelvic limbs. A complete blood count demonstrated anemia, mild neutrophilia, and lymphopenia. Serum biochemistry found an increase in ALT, ALP, blood urea nitrogen, and CK. Abdominal ultrasonography detected mild bulging of the caudal aorta and trifurcation of the iliac arteries. Increased intraluminal echogenicity and absence of blood flow were also detected using duplex doppler. The initial medical treatment was ineffective in improving clinical signs, therefore surgical repair was performed. The aorta was isolated and clamped with Satinsky forceps and incised. The thrombus fragmented during removal. A non-compliant high-pressure balloon was used to dilated and remove small fragments of blood clots from the right and left external iliac arteries. Coronary stents of 32 mm length by 2.75 mm diameter were placed to keep both iliac arteries free. Immediately after the procedure, there was a detectable distal pulse in both hind limbs...

Use of monopolar cauterization by cystoscopy for ectopic intramural ureter correction in a bitch

Background: The ectopic ureter (EU) is considered a congenital anomaly in which the ureteral aperture opens in a positionother than the bladder neck. The diagnosis involves the use of different methods or combination of image exams, including excretory urography, pneumocystography, ultrasonography, cystoscopy and computed tomography. The technics forsurgical repair should be considered evaluating the number and functionality of the EU, the location of the ureteral opening, functional condition of ipsilateral kidney and the presence of other abnormalities. The case reports aims to show thesurgical repair of an intramural EU in an English Bulldog bitch by cystoscopy-guided monopolar cautery.Case: A 1-year-old English Bulldog bitch received medical care due to a history of urinary incontinence since a few monthsof life. The animal had laboratory abnormalities compatible with lower urinary tract infection, followed by a profoundgrowth of Klebsiella sp in urine culture, and received antibiotic treatment for 21 days based on antibiogram results. Dueto a suspect EU, a urinary tract tomography was performed and indicated a congenital kidney malformation (renal dysplasia), enlargement and distal insertion of the left ureter (in comparison with the contralateral one), rising suspiciously ofits intramural progression. We choose to proceed to cystoscopy examination, in which both right and left ureteral ostiumcould be seen in the urethral region. A guide of a pigtail catheter was inserted through both ureteral ostia in order to orientthe ureteral incision. The monopolar cautery was inserted in cystoscopy working channel to section the mucosa of EUchannel on urethra region, separating the lumen of EU from the urethra and extending the incision cranially inside theurinary bladder lumen.

Determining the optimal time of gastric emptying in cats using dry or wet food

Background: Pulmonary aspiration of gastric content can result in intraoperative and postoperative complications, such as regurgitation, gastro-esophageal reflux and esophagitis. There are variations among authors about the ideal period of solid and liquid fasting. Determination of the appropriate amount of food abstinence in surgical patients is important, because of the metabolic disorders that interfere in response to anesthetic protocol or surgical intervention. Thereby, this research aimed to evaluate the appropriate period of fasting for elective anesthesia and surgical procedures in cats, by analysis of gastric emptying time based on the daily energy requirement. Materials, Methods & Results: Seven cats of mixed breed, health and with an average weight of 2.857 ± 0.3780 were evaluated by gastroscopy for the presence of food and obtaining tissue samples. To evaluate the gastric emptying time, dry and moist food were offered at two different times, 8 h and 4 h before each evaluation, with an interval of seven days between each food treatment (dry and moist). There was no significant difference in all biochemical parameters evaluated (cholesterol, glucose, and lactate) in both fasting times and food types (P > 0.05). All animals underwent gastric biopsy for histological evaluation and urease test, to discard morphological changes. After 4 h it was observed dry food [...](AU)

Quemaduras térmicas en perros y gatos / Thermal burns in dogs and cats / Queimaduras térmicas em cães e gatos

Las quemaduras se producen cuando el tejido vivo está en contacto durante un largo periodo con un objeto o sustancia caliente. Se describen varias áreas de participación, que varían de acuerdo con el potencial de reversión de la lesión, como la zona de coagulación, estasis e hiperemia. Con respecto a la profundidad de la lesión, pueden ser clasificadas de acuerdo a el espesor, en superficial, superficial parcial, parcial profunda y completa. La extensión de piel afectada se calcula en base a la "regla de los nueves", que establece que cada parte del cuerpo corresponde a un múltiplo de 9% de la superficie corporal total. Aunque es poco frecuente en los pacientes veterinarios, quemaduras graves pueden llevar a un shock al disminuir el flujo de sangre periférica. Se debe realizar como terapia tópica inicial la tricotomia amplia seguida de la aplicación de solución salina fria, lavar con solución isotónica estéril, debridamiento, aplicación de ungüento antimicrobiano como sulfadiazina de plata y cubrir con vendas húmedas no adherentes. El debridamiento del tejido desvitalizado debe realizarse lo antes posible y, preferentemente, de forma agresiva. En la imposibilidad de realización de cirugía se puede utilizar los agentes conservadores enzimáticos de debridamiento, la inmersión en el agua y la aplicación de vendajes húmedos-húmedas. Después de la formación del lecho vascular sin tejido necrótico o infectado, quemaduras extensas se pueden cerrar mediante colgajos, injertos de piel, la técnica de avance de piel, o tratadas como herida abierta hasta que sea posible el tratamiento quirúrgico. Pueden ocurrir complicaciones como infección, cicatrización excesiva y la contractura de la herida, sobre todo cuando no hay un tratamiento temprano. [...](AU)

Burns occur when living tissues are in contact for a long period with a heated object or substance. Various zones of involvement are described, ranging as the reversal potential of the lesion, they are the zone of coagulation, stasis and hyperemia. Regarding the depth of the lesion, they can be graded according to the thikness, as superficial, superficial partialthickness, deep partial-thickness and full-thickness. The extent of affected skin can be calculated based on the “Rule of Nines”, which states that each part of the body corresponds to a multiple of 9% of the total body surface. Although rare in veterinary patients, severe burns can lead to shock by decreasing of peripheral blood flow. Wide hair removal, followed by application of cold saline solution, lavage with sterile isotonic solution, debridement, application of antimicrobial ointment as silver sulfadiazine and cover with moist nonadherent dress must be performed as the initial topical therapy. The debridement of devitalized tissue should be performed as early as possible and preferably aggressively. The impossibility to performing the surgery, conservative debridement can be done with enzymatic agents, immersion in water and the application of wet-wet dress. After formation of a vascular bed free of necrotic and infected tissue, extensive burns can be closed by flaps, skin grafting techniques, skin advance techniques or treated as an open wound until surgical treatment can be possible. Complications as infection, excessive scarring and wound contracture can occur, especially when there is not early treatment. The final cosmetic result is usually satisfactory when there is surgical intervention and complete hair covering. Although rare in veterinary medicine, severe burns are challenging and unlike traumatic wounds, presents different features and therapeutic. The abundant literature nowadays is mostly human and more veterinary studies are necessary in this area.(AU)

Queimaduras ocorrem quando tecido vivo entra em contato por um longo período com um objeto ou substância aquecida. São descritas diversas zonas de acometimento, variando conforme o potencial de reversão da lesão, sendo elas a zona de coagulação, estase e hiperemia. Em relação à profundidade da lesão, estas podem ser graduadas conforme a espessura em superficial, parcial superficial, parcial profunda e total. A extensão de pele acometida pode ser calculada com base na “regra dos nove”, que determina que cada parte do corpo corresponde a um múltiplo de 9% do total da superfície corpórea. Apesar de raro nos pacientes veterinários, queimaduras graves podem levar ao choque por diminuição do fluxo sanguíneo periférico. Deve-se realizar como terapia tópica inicial a tricotomia ampla seguida da aplicação de solução salina gelada, lavagem com solução isotônica estéril, debridamento, aplicação de pomada antimicrobiana como sulfadiazina de prata e a cobertura com bandagens úmidas não aderentes.

Na impossibilidade de realização da intervenção cirúrgica, pode-se realizar o debridamento conservativo com agentes enzimáticos, imersão em água e a aplicação de bandagens úmida-úmida. Após a formação do leito vascular livre de tecido necrótico e infectado, as queimaduras extensas podem ser fechadas por meio de retalhos, enxertos cutâneos, técnicas de avanço de pele ou ainda tratadas como ferida aberta até que o tratamento cirúrgico seja possível. Como complicações, podem ocorrer infecção, cicatrização excessiva e contratura da ferida, especialmente quando não há tratamento precoce. O resultado cosmético final normalmente é satisfatório quando há intervenção cirúrgica e recobrimento piloso completo. [...](AU)

Thoracic and abdominal wall reconstruction with polypropylene mesh after high grade infiltrative fibrosarcoma resection in a dog

Background: Soft tissue sarcomas are a group of invasive malignant tumors formed by neoplastic mesenchymal cells. In most cases, the treatment require surgical resection. When sarcoma characteristics disqualify conventional tumor excision, polypropylene mesh can be used for abdominal or chest wall reconstruction. This paper aims to describe the clinical, computed tomography features, histopathlogical and immunohistochemical aspects of a chest wall fibrosarcoma, as well as to describe the tumor excision technique combined with resection of multiple ribs, diaphragm advancement and reconstruction of thoracic and abdominal wall with a synthetic polypropylene mesh. Case: An 11-year-old male Boxer was presented with a progressive growth tumor in the left paralumbar area. The invasive tumor measuring 15 cm in diameter, was firm epidermodermal coverage and was adherent to the subcutaneous tissue, having a smooth and non-ulcerative skin surface. Ultrasound of the mass consisted of a heterogeneous structure comprising paralumbar region, invading abdomen and left thoracic wall. Thoracic radiography showed no signs of nodular interstitial pulmonary pattern compatible with metastasis. The dog was submitted to a CT examination of thoracolumbar region, which demonstrated the presence of the circumscribed mass, measuring approximately 17 cm in diameter in the left paralumbar region with...(AU)
