A toxoplasmose é uma zoonose causada pelo protozoário Toxoplasma gondii, sendo uma das parasitoses mais difundidas mundialmente. O presente estudo teve como objetivo analisar a prevalência de anticorpos IgG anti-T. gondii em gatos atendidos no Hospital Veterinário da UFPR e em clínicas veterinárias do município de Palotina. Foram analisadas 100 amostras de soro sanguíneo, por meio da reação de imunofluorescência indireta (RIFI) e juntamente foi feito um levantamento epidemiológico por meio de questionário, respondido pelos proprietários dos animais, com relação as condições de vida dos felinos, com a finalidade de caracterizar fatores associados ao risco de infecção por T. gondii nos animais estudados. As informações obtidas foram analisadas pelo programa Epi Info 3,05. A prevalência de anticorpos IgG anti-T. gondii para a população analisada foi de 29% (29/100). Dentre as variáveis estudadas, o acesso à rua, a outras casas, ao telhado, a presença de pombos na residência, o hábito de caçar, o fato de comer restos de comida e a idade (acima de um ano), foram associadas significativamente com a presença da infecção pelo protozoário. As informações obtidas são relevantes para caracterizar fatores de risco e vias de transmissão da toxoplasmose nos animais estudados e elaborar estratégias para o controle e profilaxia da doença entre os felinos domésticos da região.

Background: Hermaphroditism is a rare congenital disease that causes ambiguous sexual features. True hermaphrodites have testicular and ovarian tissue, whereas pseudohermaphrodites have only one type of gonadal tissue, genitalia, but secondary characteristics of the opposite sex. Pseudohermaphrodites are classified as male or female according to their gonads. 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 male pseudohermaphrodite 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, complete blood 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 the exploratory celiotomy found a normal size prostate and two round organs resembling testicles connected to a uterus-like tubular structure. The patient underwent surgical abdominal exploration that confirmed the ultrasonographic findings and led to gonadohysterectomy. Also, clitoridectomy and urethrostomy were performed to excise the protruded structure and maintain normal urethral patency. The histopathological examination of the clitoris and penis confirmed it was a male genital organ, however, the abdominal structures were compatible with the testicles, epididymis, uterus, and even a broad ligament. These organs are normally found in cases of male pseudohermaphroditism. The testicles were histologically composed of regular seminiferous tubules, single layer Sertoli cells but there were no spermatogenic cells. After ten months of follow-up, the patient was alive, without urination impairment or any other clinical signs.Discussion: The animal presented the protrusion of the penile structure as the sole clinical sign. The reproductive system had a female origin, been possible its masculinization due to high testosterone concentration that induced the development of Wolff ducts, resulting in the formation of the epididymis, deferent ducts, and seminal vesicles. In these cases, it led to an enlarged clitoris. The patient described had hormonal levels compatible with a neutered male/female or a female in anestrus. The clinical signs become evident as the clitoris gets hypertrophied increasing the sensibility, resulting in constant licking of the mucosa, chronic inflammation, and mucopurulent discharge. This patient was diagnosed with male pseudohermaphroditism as it had cryptorchid male gonads along with the uterus and external genitalia of a female dog but containing traces of male genitals such as the os clitoris. Surgery is indicated when there are clinical signs or when the clitoris had an os clitoris or urethra due to an intersex abnormality. The surgical resection of the external male genitalia associated with the excision of the internal reproductive tract treated while preserving the urethra in this animal. Clitorectomy is a simple technique and creates a normal female anatomy ending the clinical signs of the exposed clitoris and improving the quality of life.Clitoridectomy and Urethrostomy in a Pseudohermaphrodite Dog

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. Despite intensive medical treatment, the patient evolved to respiratory distress and died on the sixth day after surgery. At necropsy, there were thrombi in the lumen of the arteries and several organs in addition to a large hyaline thrombus occluding 80-90% of the aortic lumen and left femoral artery. In the trifurcation region, clots were present, and stents placed in the iliac arteries were also occluded.Discussion: The occurrence of aortic and iliac thrombosis is associated with several conditions, including neoplasia, chronic kidney disease, heart failure, gastric dilatation-volvulus, hypothyroidism, and hyperadrenocorticism (HAC). In this case, the underlying cause of thromboembolism was supposed to be related to an endocrine condition, since the patient had clinical signs compatible with HAC; however, the low-dose dexamethasone suppression test was borderline and further examination could not be afforded. The diagnosis of thrombosis at the iliac trifurcation was obtained through ultrasonographic examination. Computed tomographic and nuclear resonance imaging could have been applied as well. The medical management of the thromboembolic disease was based on anticoagulant therapy with both heparin and clopidogrel in association with surgical thrombectomy and coronary stents placement. Despite the efforts, the patient died shortly after the surgical procedure, which was expected since high rates of mortality and morbidity is often related to the thromboembolic ischemia. The necroscopic examination of the animal found thrombi at the stents, cranial aorta, and microscopically in several tissues. The failure to directly treat the cause of the thrombus, which could not be diagnosed in time, may negatively interfered in patient survival time. The thrombectomy and coronary stents placement reestablished the femoral pulse immediately after surgery, which has been reported in other studies. The surgical resolution of aortic thrombus should be addressed in further studies.
