Ovarian and Uterine Horn Agenesis Accompanied by Ectopic Fetal Mummifcation in Canine

Background: The uterine horn agenesis or aplasia is a rare anomaly consisting of absence or incomplete development of the paramesonephric ducts that origin the uterine horns. This change occurs during fetal formation and may occur concomitantly to agenesis of the ovary and/or ipsilateral kidney. The extra-uterine pregnancy consists of fetal growth outside the uterine cavity and can occur as a tubal or abdominal pregnancy. We report here the case of a 7-years-old mix breed dog, attended at the Veterinary Hospital of the Federal University of Mato Grosso, with accidental diagnosis of agenesis of uterine horn and ovaries and ectopic fetal mummifcation.Case: A 7-years-old mix breed dog, not spayed, was attended at the Veterinary Hospital of the Federal University of Mato Grosso (HOVET-UFMT), complaining of mucous bloody vaginal discharge. The patient had regular estrus and was multiparous. There was no mating history in the last estrus neither trauma over the past months. In previous pregnancies the patientpresented eutocic labors. On physical examination the dog showed apathy although it was alert, pale mucous membranes, presence of perivulvar blackish secretion and discreet abdominal enlargement. As preoperative exams, a complete blood count, liver and renal function (serum creatinine and alanine aminotransferase) were performed. It has also performedthe abdominal ultrasound examination, which revealed the presence of uterus flled with hypoechoic luminal content and a thickened and irregular wall. The patient was referred to therapeutic ovariohysterectomy (OHE). After anesthesia and antisepsis, the access to the abdominal cavity was made, where there was a mummifed fetus with approximately 15.5 cmfrom neck to tail set, equivalent to 57 days of gestation. After removal of the papyraceus fetus, the uterus was found and then, when exposed, there was only the left uterine horn flled by content and ovarie, both were removed. After inspection, the synthesis of the abdominal cavity was carried out as the routine. During the postoperative period, the patient had no complications or other clinical signs similar to those observed in the initial presentation. Antibiotic (enroﬂoxacin 5 mg/kg every 12h), analgesic (dipyrone 20 mg/kg every 8 h) and non-steroidal anti-inﬂammatory (meloxicam 0.2 mg/kg every 24 h) were prescribed. The fetus and uterus were sent to the Veterinary Pathology UFMT Laboratory (PVL-HOVET).The fetus was covered by omentum and fat. After the initial incision, there was a hard fbrous capsule surrounding the mummifed fetus. There were no recent signs of rupture or scarring resulting from previous trauma in the uterus. Its size was 15x4.8x2.8 cm and it was flled out with mucus bloody brownish secretion (pyometra). Microscopically, had purulent inﬂammatory infltrate, diffuse and severe in mucosa and submucosa associated with cell debris and moderate hyperplasia glands containing microabscesses inside.Discussion: Reports of extra-uterine fetal mummifcation in dogs and cats are scarce. Even being reported infrequently in dogs if congenital uterine and ovarian abnormalities are found during surgery, a detailed inspection of the abdominal cavity should be performed in order to rule out the possible presence of the ipsilateral ovary. Even with the lack of specifc clinical signs, fetal ectopy can be diagnosed through a detailed clinical examination and image exams. Exploratory laparotomy can be used as a diagnostic and therapeutic tool, since the treatment is the excision of ectopic tissue and OHE in cases of uterine rupture.Keywords: aplasia, fetus, mummifcation, unicornuate uterus.

Sertoli Cell Tumor

Background: Sexual development disturbances (SDD) are divided in SDD with XX genotype (SDD XX) and SDD with XY genotype (SDD XY). Among SDD XY, the Müller´s duct persistence syndrome (MDPS) is characterized by XY karyotype individuals with male external genitals; however, with internal female reproductive organs such as uterine horns, uterus, and cranial vagina portion. The MDPS cases and their related complications are considered very rare in veterinary medicine. The aim of the present case report is to describe the clinical and pathological aspects of a MDPS case associated with cryptorchidism, Sertoli cell tumor, and pyometra in a Miniature Schnauzer dog.Case: A 7-year-old male Miniature Schnauzer weighting 7 kg was brought to veterinary consultation due to owner´s complain of frequent vomiting, apathy, abdominal algia and progressive scrotal enlargement in the last two months. Physical exam reveals hyperthermia (39.7°C), discrete dehydration, enlarged popliteal lymph nodes as well as scrotum enlargement with only one palpable testicle. A blood sample collected for complete blood count showed regenerative anemia, thrombocytopenia, and neutrophilia with left shift in the leukogram. Abdominal ultrasound examination indicated the presence of a tubular structure filled by anechoic content extending from the scrotum to caudal abdomen. Moreover, a 6.39 x 8.54 cm heterogeneous mass in the medial mesogastric region became evident. The patient was hospitalized and submitted to exploratory laparotomy after 24 h due to rectal temperature increase (41°C), worsened abdominal pain and intense apathy. There was free purulent liquid in abdominal cavity and two uterine horns were documented. The left uterine horn passes through inguinal ring and both horns were filled by purulent material. At the right uterine horn extremity there was the mass previously document at ultrasound. The structures were removed and sent to histopathological examination. The microscopic exam confirmed testicular and uterine tissue; furthermore, a Sertoli cell tumor and pyometra were also characterized. The dog was kept at the hospital receiving fluid, antibiotics, analgesics, and anti-inflammatory therapy. After five days the animal was discharged with clear clinical recover. A sample for karyotyping was collected from the oral mucosa which reveals a XY karyotype in the dog. By this way it was concluded that the dog suffers from a SDD XY with MDPS associated to cryptorchidism, Sertoli cell tumor and pyometra. Discussion: The MDPS cases are often associated with cryptorchidism and testicular tumors. Miniature Schnauzers is one of the most affected dog breeds with this condition, and the heritability pattern is already described. Most cases are identified in adult to old-aged dogs after vague clinical signs investigation such as apathy, anorexia and abdominal or inguinal enlargement, as observed in the present report. When Sertoli cell tumor are present, the hormone secretion pattern of this neoplasia may influence complications occurrence. Once higher estrogen levels may induce endometrial gland proliferation, hydrometra and pyometra are among these complications, as well as reduced hematopoiesis. Moreover, progesterone levels could be also increased favoring pyometra pathophysiology. By conclusion, despite very rare, MDPS should be investigated in Miniature Schnauzers with vague clinical signs, especially cryptorchidic ones. Karyotyping and histopathology were crucial to confirm the diagnosis. Moreover, no other case with MDPS, cryptorchidism, Sertoli cell tumor, and pyometra was found in the published literature consulted.

The aim: demonstration of our experience of surgical treatment of patients with migrated intrauterine device (IUD) into the abdominal cavity. The results of surgical treatment of migrated IUDs in the pelvic cavity are summarized in 17 women. The average age of the patients was 33,23,4 years. The timing of implantation of the IUDs varied from 10 days to 24 months. In all cases, the intra operational finding was T-shaped a copper device. The reason behind the women's consultation was an increase in pain syndrome in the lesser pelvis (n=15), dysuric phenomenon (n=1) and the onset of pregnancy (n=1). Perforation of the uterus and migration of the spiral occurred from 10 days to 2 years after its implantation. All patients were operated laparoscopicaly. The average duration of operations was 45,510,5 minutes. In the postoperative period there were no complications from the pelvic organs and postoperative wounds. The period of hospitalization of patients was 3,50,7 days. In all cases there was a regression of clinical signs and recovery. In one pregnant patient (gestation period 5-6 weeks) the pregnancy proceeded without particular pathological abnormalities and resulted in the birth of a full-term child. Laparoscopic removal of the IUD migrating from the uterine cavity to the abdominal cavity is the method of choice in the treatment of this group of patients, avoiding development of intra- and postoperative complications and a shorter length of stay in the hospital. The effectiveness of the procedure reaches 100%. The most common cause of complication of the IUD is the perforation of the uterus during its implantation.

Intestinal lymphoma is the second most common form of lymphoma in dogs. It is characterized by the presence of neoplastic lymphocytes in the gastrointestinal tract or mesenteric lymph nodes. The chief clinical signs are vomiting, diarrhea, anorexia and weight loss. The diagnosis is made through fine needle aspiration and cytology, or by tissue biopsy and histopathology, and chemotherapy is the treatment of choice. We report a case of intestinal lymphoma in a five years old Boxer, presented with history of hematochezia and lethargy of 7 days duration, and 20 days of anorexia and persistent weight loss. Abdominal ultrasonography revealed free fluid in the abdominal cavity, and an intestinal mass. Exploratory laparotomy was performed and a tissue biopsy was performed. Histopathology confirmed the diagnosis of intestinal lymphoma, but the patient died during the surgical procedure.

ABSTRACT A 6 yr old female spayed Chihuahua was presented for evaluation of intermittent vulvar discharge, stranguria, and vomiting. This dog had an ovariohysterectomy as a puppy and did not experience any evidence of estrous until 4.5 yr later. The owner had been using a topical hormone replacement therapy (estradiol spray) twice daily for the duration of the dog’s clinical signs of 1 yr. On presentation, the dog had truncal alopecia, comedones, enlarged vulva with a malodorous, and purulent discharge. Bloodwork showed a leukocytosis with a neutrophilia, döhle bodies, and moderate toxic changes. An abdominal ultrasound revealed an enlarged uterine stump with a thickened wall, ovoid projection cranially, and echogenic luminal contents. An exploratory laparotomy identified an enlarged cervical stump. Histopathology revealed chronic suppurative vaginitis with endometritis, necrosis, and intraluminal coccoid bacteria. The dog recovered well from surgery. A baseline estrogen level post operatively was measured at 56.4 pg/mL (<50.0 pg/mL for a spayed bitch), at this time, the dog had been separated from the owner for 7 days. After surgery, the clinical signs disappeared, and the dog’s dermatologic changes improved. This is the first reported case of stump pyometra following exposure to the owner’s topical estradiol replacement medication.

A juvenile, wild-caught prairie falcon ( Falco mexicanus) kept for falconry was presented to a veterinary hospital for intermittent opisthotonos and torticollis. Clinical examination, complete blood count, serum biochemistry panel, and fecal analysis were unremarkable. Clinical signs did not resolve, and the bird was euthanized 6 mo after the appearance of clinical signs. Autopsy revealed a mild, unilateral hydrocephalus and nematodes within the thoracic air sac. Histopathology demonstrated mild, unilateral hydrocephalus; scattered glial nodules; meningeal nematode sections; and meningeal and intraventricular embryonated eggs. Morphology and molecular characterization were consistent with the air sac nematode Serratospiculum or Serratospiculoides spp. Air sac nematode infection can be associated with air sacculitis or pneumonia in falcons. Aberrant migration of air sac filariid nematodes Serratospiculum or Serratospiculoides spp. into the nervous system resulting in clinical disease is rare, but should be included in the differential diagnosis of neurologic diseases in falcons.

Abstract Background Amoebiasis is a parasitic disease caused by Entamoeba histolytica, which affects people living in low- and middle-income countries and has intestinal and extraintestinal manifestations. To date, knowledge on coronavirus disease 2019 (COVID-19) coinfection with enteric parasites is limited, and E. histolytica coinfection has not been previously described. Here we present the case of a patient with COVID-19 who, during hospitalisation, presented a clinical picture consistent with an amoebic liver abscess (ALA). Case presentation A 54-year-old man, admitted as a suspected case of COVID-19, presented to our hospital with dyspnoea, malaise, fever and hypoxaemia. A nasopharyngeal swab was positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by reverse-transcription polymerase chain reaction. After 7 days, he developed diarrhoea, choluria and dysentery. An abdominal ultrasound showed a lesion compatible with a liver abscess; stool examination revealed E. histolytica trophozoites, and additional serology for E. histolytica was positive. After 12 days of treatment with metronidazole, ceftazidime and nitazoxanide, the patient reported acute abdominal pain, and an ultrasound examination revealed free liquid in the abdominal cavity. An emergency exploratory laparotomy was performed, finding 3000 mL of a thick fluid described as “anchovy paste”. Computed tomography scan revealed a second abscess. He ended up receiving 21 days of antibiotic treatment and was discharged with satisfactory improvement. Conclusion Here we present, to the best of our knowledge, the first report of ALA and COVID-19 co-presenting. Based on their pathophysiological similarities, coinfection with SARS-CoV-2 and E. histolytica could change the patient’s clinical course; however, larger studies are needed to fully understand the interaction between these pathogens.

Capillaria Hepatica ◽

Histopathologic Exam

Background: Capillaria hepatica is a nematode, zoonotic, with worldwide distribution. The main hosts are rodents, nevertheless other mammals can be affected. Although the parasite has high affinity for the liver, it rarely causes a hepatic disease in domestic animals and humans. The diagnosis is difficult and usually a biopsy is required. The treatment is difficult and is based in anti-helminthic and corticoid, but prevention is the best strategy against the disease. The aim of the present report is to describe a case of hepatic capillariosis in a dog approaching the clinical signs, diagnosis and therapeutic. Case: A 12-year-old Brazilian Terrier bitch, with a history of visit to the farm and regular hunting of rats, frogs, birds and other wild animals, was attended with hyporexia and apathy. At the physical exam the dog presented elevation of rectal temperature, intense jaundice and abdominal pain. In the biochemical exams was noticed a slight increase in globulins and a sharp increase in alkaline phosphatase (AP), total, direct and indirect bilirubin, suggesting a liver injury. In the ultrasonographic exam, hepatomegaly with dispersed hyperechoic areas were observed, suggesting hepatic steatosis. The patient was treated with ursodesoxicolic acid and S-adenosil metionin for 30 consecutive days, showing a clinic improvement. Two months after the end of the treatment the animal worsened, showing jaundice, ascites, motor incoordination, weakness, difficulty in food and water ingestion and changes in the mental state. In the complete blood count was observed a macrocytic hypochromic regenerative anemia, leukocytosis with neutrophilia and monocytosis and thrombocytopenia. In biochemical exams was detected decrease in creatinine and albumin and increase in alanine aminotransferase and AP, suggesting hepatopathy by biliary obstruction. There were performed exams for leishmania and ehrlichiosis that tested negative. In the ultrasonographic exam it was noticed that the liver had the same alterations and the presence of free fluid in the abdominal cavity. Due to the deterioration of the clinical picture a blood transfusion was necessary, however the patient worsened and presented respiratory difficulty for a bilateral pleural effusion. Then, the fluid was drained and a treatment with S-adenosil metionin, silymarin, ursodesoxicolic acid, doxycycline and prednisolone was started. After 17 days, a hepatic biopsy was performed, but the patient died at the surgery desk. Samples from the liver were collected for histopathologic exam. The diagnosis was confirmed in hepatic capillariosis and periportal chronic hepatitis, with the visualization of numerous parasites structures with bioperculated barrel shape. Discussion: Due to the nonspecific clinical alterations observed in the patient and the low prevalence of C. hepatica in domestic animals, there was a difficulty in the diagnosis which lead to a symptomatic, nonspecific and inefficient treatment that culminate with the death of the patient. The histopathologic exam of the liver is the best manner to find the correct diagnosis of C. hepatica infection, once the parasites eggs remains in the liver parenchyma wrapped by fibrosis and aren´t eliminate in the feces. The eggs elimination in the environment just occur after the death of the animal. Although there didn't exist a consensus about hepatic capillariosis treatment yet, if the diagnosis were done earlier, a specific treatment with better chances of a good result could be performed. We concluded that hepatic capillariosis should be included in differential diagnosis for patients with hepatic syndrome, mainly if the animal had a hunting habit and if it had access to surroundings with high rats’ infestation.

A Furioso-North Star mare, aged 8 years, was examined for colic signs. The mare had a history of dystocia and post partum vaginal lacerations, acute endometritis and laminitis approximately one year before the admission for colic. Signs of persistent abdominal pain, moderate distended abdomen, non-passage of manure, fever, tachycardia, tachypnoea, congested mucus membranes, and “toxic line” were recorded. No intestinal borborygmi were present in the four quarters of the abdomen. On rectal examination, the colon, the ventral band of the caecum, the right ovary and the uterine horn were palpated on the right side of the abdomen. The spleen, the nephrosplenic ligament, the left ovary and a firm, distended and painful small intestine (SI) loop were palpated on the left side. The left uterine horn and the adjacent broad ligament were not detectable. Percutaneous abdominal ultrasound evaluation revealed a large amount of fluid in the abdominal cavity, SI distention and absence of peristalsis. Abdominocentesis yielded approximately 20 ml of red-tinged peritoneal fluid with increased mean protein concentration (5.2 mg/dl), white blood cell count (12,550 cells/μl), and lactate (14 mmol/dl). A presumptive diagnosis of SI strangulation was made. Surgical resection of the affected intestinal loops was recommended. Due to poor prognosis and financial limitations, the mare was euthanized. Post mortem macroscopic diagnosis was a herniation of 3 metres of the mid-jejunum through the left mesometrium, resulting in a complete and complicated strangulation. To prevent this type of SI strangulation, we recommend transrectal palpation of the urogenital tract (including the broad ligament) after foaling. If a defect is identified, we recommend flank laparoscopy for correction.

Determining Factor

Background: Snakebites occur frequently among humans and animals. In Brazil, about 23,000 cases of snakebite involving humans were recorded in 2016, 11% of them caused by venomous snakes. In the region of Cuiabá, capital of Mato Grosso, the highest occurrence is of snakes of the genus Bothrops (81%), followed by Crotalus (4%). Bothrops venom has proteolytic, coagulant and hemorrhagic effects, whereas Crotalus venom is neurotoxic, myotoxic and nephrotoxic. This paper reports on three cases of Bothrops snakebites in dogs treated at the Veterinary Hospital of the Federal University of Mato Grosso in 2017.Cases: Three dogs were treated showing clinical signs of snakebite, possibly by Bothrops, since their owners reported that these are the snakes most frequently found where they live. This information is consistent with the known geographic distribution of snakes of the genus Bothrops in the state of Mato Grosso, Brazil. In the first report (Case 11), the patient was bitten on two different occasions in a five-month interval, and died presumably due to anaphylactic shock caused by the venom injected by a second snakebite (Case 12). In both episodes, the animal presented a swollen face and neck, dyspnea and eye bleeding, and these signs were more severe in the second episode. Case 2 was a dog with severe neck and chest swelling and pain. The owner of this dog reported that he had taken his dog for a walk in the countryside, along with the dog of Case 1, and had returned home with both dogs about three hours before the consultation. Case 3 was a Rottweiler living at a small family farm located 67 km from Cuiabá. The animal presented with slight swelling and pain in the left forelimb, and puncture wounds on the lower limb. Neutrophilic leukocytosis was observed in cases 1 and 3. In addition, Case 12 (the second episode of Case 1) presented with thrombocytopenia and increased prothrombin time and activated partial thromboplastin time. The dog of Case 2 presented no hematological or biochemical alteration. All the dogs received antivenom serum and supportive care.Discussion: Based on the clinical signs of local swelling with bleeding and absence of neurological signs, the snakebites were attributed to the genus Bothrops. In Case 12, blood clotting tests showed non-coagulation. The greater severity of Case 1, which culminated in death, was attributed to anaphylaxis due to prior exposure or the larger amount of venom than that injected in Case 2, since the two injuries were inflicted in the same environment on the same day, probably by the same snake. Neutrophilic leukocytosis may be indicative of an inflammatory reaction, while thrombocytopenia and clotting changes are associated with the hemorrhagic activity of Bothrops venom. Death by snakebite is directly linked to the amount of venom injected, the envenomation site, and the time between the bite and the beginning of treatment. This explains the moderate signs presented by Cases 2 and 3, whose injuries were inflicted on the neck and forelimb, unlike the dog of Case 1, which was bitten on the head on two occasions. It was concluded that Bothrops venom causes systemic and local alterations characterized by pain, swelling, necrosis and bleeding. Early access to antivenom treatment is essential to neutralize clinical signs and prevent worsening of systemic poisoning. The determining factor in snakebite deaths is the amount of injected venom and the time elapsed between the injury and the beginning of treatment.

Dermatophyte Infection

Dermatophytosis, commonly known as ringworm, is a zoonotic disease caused by complex fungi that grow as hyphae and attach to the skin, hair and nails or claws. About 40 species of fungi of the genera Microsporum spp., Trichophyton spp. and Epidermophyton spp. are considered dermatophytes, and Microsporum canis is the genus most commonly isolated from cats. This study investigated the occurrence of dermatophytes in cats without clinical signs of skin diseases. The study involved the physical examination of 50 clinically healthy cats and the collection of samples for direct examination and fungal culture at a university veterinary hospital. The resulting data were evaluated by the chi-square association test. Of the 50 cats, 11 (22%) presented dermatophytes, with a predominance of Microsporum spp. The other 39 animals were diagnosed for non-dermatophytic fungi. Sex, breed and the presence of contactants showed no statistical difference, although there was a predominance of adult animals. The high dermatophyte infection rate confirms that cats without clinical signs can harbor these fungi, acting as asymptomatic carriers, contaminating the environment and increasing the infection rate. This study confirms that cats without clinical signs can be carriers of ringworm, which underscores the importance of the adoption of control methods even for clinically healthy animals.
