Background: Dioctophyma renale is a giant worm, nematode parasite, which infest dogs, rarely humans or other domestic and wild species. The life cycle is complex and infestation occurs by ingestion of aquatic oligochaete (annelid), fsh and frogs. This nematode normally installs in the right kidney of dog, however, there are reports of ectopic migration, such as, for example, in the stomach, abdominal cavity, liver, bladder, ureters, urethra, scrotum, uterus, ovaries, mesenteric lymph nodes, mammary gland, thoracic and pericardial cavity. The aim of this work is to report the location of erratic Dioctophyma renale in the left testicle of a dog. Case: A mongrel dog, about 4 years old, weighing 7.7 kg, rescued from the street after being hit by a car was admitted at the Veterinary Clinical Hospital of CAV / UDESC. Clinical examination showed no signifcant changes, except for the crackling of pelvic bones, suggesting pelvic fracture. Pelvic radiography and abdominal ultrasound were requested, and complete blood count as pre-anesthetic evaluation was performed. The blood count showed leukocytosis with neutrofilia with a regenerative left shift. The patient was referred for pelvic fxation and in the same procedure orchiectomy was performed. The premedication was acepromazine 0.05 mg/kg and morphine 0.5 mg/kg, administrated intramuscularly. Anesthesia was induced with propofol and maintained with isoflurane inhalation. Epidural anesthesia was performed with bupivacaine 0.26 mL/kg combined with morphine 0.1 mg/kg. During surgery it was noted that the left testicle presented itself deformed. The material has been collected and sent for histopathological analysis. In this analysis the presence of a male specimen of Dioctophyma renale, inside the testicle, with focal cavity formation was observed, indicating destruction of testicular parenchyma surrounded by moderate infltrate of macrophages and plasma cells, suggesting parasitar orchitis. In abdominal ultrasound no evidences of abnormalities such as nephropathy were observed and no evidence of the presence of another Dioctophyma renale in kidney or any region of the abdominal cavity were observed. Discussion: Among the many reports of ectopic locations of the mentioned nematode, no report was found related to your intratesticular migration. The confrmation was given based on morphological characteristics, color and size of the parasite (giant worm). Diagnosis usually occurs by accidental necropsy fndings or surgical fndings, and the treatment of choice is surgical removal of the parasite. Although the ultrasound is not a suitable diagnostic method for dioctophymosis in dogs, it can show kidney destruction compatible with the disease. In this case, abdominal ultrasonography demonstrated no presence of the parasite in the kidneys or in any region of the abdominal cavity. When there is kidney parasitism, it has parenchymal destruction, leaving only the renal capsule in advanced cases; in these cases, right kidney is more often stricken and in human beings dioctophymosis already have been reported like kidney tumor. This nematode is more often found in dogs than in cats, horses or any other domestic animal. It can be concluded that the behavior of intratesticular infestation resembles the picture observed in renal parasitism, with parenchymal destruction. The complete destruction probably should happened if orchiectomy had not been performed. Keywords: Dioctophyma renale, testicle, dog

Initial Symptoms

Abstract Background Ganglioneuromas (GNs) are extremely rare, slowly growing, benign tumors that can arise from Schwann cells, ganglion cells, and neuronal or fibrous tissues. Due to their origin from the sympathetic neural crest, they show neuroendocrine potential; however, most are reported to be hormonally inactive. Nevertheless, complete surgical removal is recommended for symptom control or for the prevention of potential malignant degeneration. Case Report A 30-year-old female was referred to our oncologic center due to a giant retroperitoneal and mediastinal mass detected in computed tomography (CT) scans. The initial symptoms were transient nausea, diarrhea, and crampy abdominal pain. There was a positive family history including 5 first- and second-degree relatives. Presurgical biopsy revealed a benign ganglioneuroma. Total resection (TR) of a 35 × 25 × 25 cm, 2550-g tumor was obtained successfully via laparotomy combined with thoracotomy and partial incision of the diaphragm. Histopathological analysis confirmed the diagnosis. Surgically challenging aspects were the bilateral tumor invasion from the retroperitoneum into the mediastinum through the aortic hiatus with the need of a bilateral 2-cavity procedure, as well as the tumor-related displacement of the abdominal aorta, the mesenteric vessels, and the inferior vena cava. Due to their anatomic course through the tumor mass, the lumbar aortic vessels needed to be partially resected. Postoperative functioning was excellent without any sign of neurologic deficit. Conclusion Here, we present the largest case of a TR of a GN with retroperitoneal and mediastinal expansion. On review of the literature, this is the largest reported GN resected and was performed safely. Additionally, we present the first systematic literature review for large GN (> 10 cm) as well as for resected tumors growing from the abdominal cavity into the thoracic cavity.

Background: Cutaneous horn is a circumscribed exophytic lesion composed of dense, compact keratin with hyperplastic epidermis, which is primarily orthokeratotic and may include foci of parakeratosis. The hyperkeratotic protuberance resembles a horn but lack bone. In humans, it is well-documented with a wide range of primary epidermal lesions identified. In dogs, the reports are rare and brief. The diagnosis is based on its appearance and excisional biopsy reveals the triggering lesion. The objective of the present work is to describe the clinical presentation, predictive benignancy finds, treatment and follow-up of a case of cutaneous horns that arose from anal mucocutaneous boundary in a dog.Case: A 6-month-old male Pug presented two tumors in the anus noted in the early months of life. Complete blood count, serum chemistry profile, surgery, histopathological analysis and postoperative outcome were performed. Possible relapses were follow-up until 11 months after surgery. On physical examination, the dog was otherwise healthy. The two horn-like tumors were protruding from the mucocutaneous junction of the external anal sphincter in a sun-protected area. Both were higher than wide in base or, in other words, they had a high height-to-base ratio. During surgery, the masses were excised using an electronic scalpel and sent to histopathological analysis. The post-operative care consisted of cephalexin and meloxicam prescriptions. Also, it was recommended 0.9% NaCl solution wound flushing followed by topical chlorhexidine digluconate solution (1%) whenever dirt or defecation were noticed. The surgical wound healed after two weeks by second intention. Histopathology found well-delimited masses that covers the epidermis and dermis and displaces the cutaneous appendages towards the underlying musculature with an aggregate of lymphoplasmohistiocytic inflammatory infiltrate in the adjacent dermis. These finds and the presence of orthokeratotic hyperkeratosis and epidermis hyperplasia confirmed the clinical diagnosis of cutaneous horns. There were no signs of malignance. After surgery, no relapse occurred.Discussion: To the best of the authors’ knowledge, this is the first confirmed case of cutaneous horns in mucocutaneous junction. Furthermore, the tumors were found in a region with little exposure to sunlight which is unusual. The tumor’s narrow bases and the absence of continuous and dense inflammatory infiltrate shown to be predictive of benignancy as occurs in human beings. During surgical planning, it was decided not to establish wide margins around the masses. The decision considered the morphological signs of benignancy of the tumors described for human beings as no surveys about prevalence of benignity or malignancy associated with cutaneous horns were found in dogs. In addition, a more extensive excision could promote anal sphincter dysfunction. There was no tumors recurrence suggesting that the primary underlying lesions have been healed and confirming that predictive benignancy morphological characteristics applied in human patients can be useful for small animals. Veterinary clinicians and surgeons must be in constant vigil of cutaneous horns uncommon presentations and report them to create a solid database that can be useful for prognosis and surgical planning. The morphological predictive factors can be applied to avoid unnecessary extensive surgical excisions that could lead to functional or cosmetic impairment.

Abstract Background Cryptorchidism in dogs is of clinical concern due to its association with development of Sertoli cell tumours, seminomas and spermatic cord torsion. A patent inguinal ring has been found as a risk factor for peritoneal content migration and inguinal hernias. This study reports a case of bowel migration through a patent inguinal ring in a bilaterally cryptorchid dog and incarceration within the vaginal tunic of the left testicle. Case presentation A three-and-a-half-year-old bilaterally cryptorchid Lhasa Apso with a history of anorexia, vomiting, stranguria and inability to defecate was diagnosed with bowel incarceration in the vaginal tunic of a retained left testicle. Surgery performed under epidural anaesthesia with acepromazine/butorphanol premedication revealed a loop of the colon entrapped in the vaginal tunic of the retained left testicle. The incarcerated bowel was thoroughly examined for viability and repositioned into the abdominal cavity. The inguinal ring was repaired and bilateral cryptorchidectomy performed. Conclusion Cryptorchidectomy in dogs is often considered when there is concern for neoplasm or torsion of retained testes. However, this report suggests that cryptorchidectomy should be considered also to preclude the possibility of bowel obstructive emergencies.

The current study aimed to isolate bacteria that harbour various animal food products like meat, chicken and seafoods collected from the abattoir, butcher shops and local seafood market and to determine the antimicrobial resistance pattern of isolated pathogens which are responsible for various foodborne illnesses in human beings. A total of forty raw animal product samples were collected from the abattoir, butcher shops and local seafood market of Visakhapatnam. The samples selected for the study include raw chicken, meat, crab, prawns and different varieties of fish. A classic random sampling technique was employed to collect the study samples. All the samples were processed immediately using standard microbiological protocols. The bacteria isolation and characterization were done by studying morphological characteristics with staining methods, cultural characteristics by isolating and growing the pathogenic microorganisms in various selective and differential culture media. Antimicrobial susceptibility testing was performed by the Kirby -Bauer method by following Clinical and Laboratory Standards Institute (CLSI) guidelines. EDTA-Disc Potentiation Test and Imipenem-EDTA Double disc synergy test are used to detect the metallo beta-lactamase production of isolated pathogens. The highest number of isolates belong to Salmonella species (18), Pseudomonas aeruginosa (18) followed by Vibrio species (14) and few isolates belong to Enterobacter species (4). Majority of the microbial isolates obtained in the current study were multidrug resistant. The isolates from the abattoir environments, slaughterhouses, fish markets were found to exhibit variable resistance pattern to aminoglycosides, macrolides, β-lactams, cephalosporins, quinolone antibiotics used in the present study and at the same time most of them were sensitive to carbapenem antibiotic imipenem. Antimicrobial resistance (AMR) prevents the designing and assessment of effective interventions. If such a link can be established, then the tracking of antibiotic use and consumption data could be furthermore used as a surrogate indicator for the risk of potential antibiotic resistance (ABR) emergence.

✓ Brain metastasis in patients with disseminated nonseminomatous germ cell tumor (NSGCT) has been considered to occur rarely. The authors present the case of a 43-year-old man with an enlarged left testicle, a palpable inguinal tumor, multiple lung tumors, and a large cerebellar tumor. In separate operations, performed 1 month apart, the large cerebellar tumor and the testicular tumor were excised. Elements of teratocarcinoma, embryonal carcinoma, and choriocarcinoma were present in both the brain and testicular tumors. After chemotherapy in which bleomycin, etoposide, and cisplatin were used, the lung tumors and also the surrounding metastasis disappeared; the patient now leads a useful life and remains free from cancer in all organs. The authors suggest that surgical removal of tumor before initiating radiotherapy and chemotherapy for large brain metastasis from NSGCT will produce better results than using the nonsurgical treatments alone.

Abstract Morphophysiological species researches are fundamental, and diagnostic imaging is an excellent technique, already used in wild animals, with great application, not invasive and provide real-time information of each body. Amazonian manatees are on the list of endangered animals classified in the vulnerable category and knowledge of the normal pattern of ultrasound anatomy of organs and tissues is important for the maintenance and well-being of captive specimens contributing to reintroduction actions. The objective of the study was to standardize the examination technique and describe the ultrasound findings of the liver, gallbladder, stomach, urinary bladder and the subcutaneous tissue of the abdominal region in Trichechus inunguis, in order to contribute with the anatomical and sonographic knowledge and assist in the diagnosis and prognosis diseases. The study used 18 animals to describe the normal sonographic anatomy in the abdominal cavity of the Amazonian manatee. During abdominal scan, it was possible to visualize the features of the liver, gallbladder, stomach, urinary bladder obtained satisfactory results in this study. Therefore, other structures were not primarily identified by the reduced time, lots of fat and gases in intestines of animals.

Splenosis is a benign condition which results from the self-implantation of splenic tissue on intra or extraperitoneal surfaces, after splenic trauma or splenectomy. Patients are usually asymptomatic but may present with varied symptoms related to the implantation site. The diagnosis is a challenge because abdominal splenosis can mimic several diseases, including neoplasm. The gold standard examination for its diagnosis is scintigraphy with 99mTc-labelled heat-denatured erythrocyte. When splenosis is found in an asymptomatic patient, surgical removal is not indicated. A 57-year-old male patient presented with sporadic epigastric pain and a suspected mass in the recto-sigmoid transition. Abdominal ultrasound, CT and MRI identified this mass, its characteristics and location, but failed to distinguish its nature. However, given the patient’s past history of splenectomy and because the mass showed a similar sign to that of the splenic parenchyma, a hypothesis of abdominal splenosis was raised, which was confirmed by scintigraphy with 99mTc-labelled heat-denatured erythrocyte. In this case, the diagnosis was obtained before the patient was subjected to more invasive procedures, which are associated with high morbidity, and, as in most cases, no targeted intervention was necessary.

Uterine tumours are rarely reported in cats. This case report describes two older queens with typical presentations consistent with pyometra. However, histopathology of the uteri diagnosed each case with concurrent uterine neoplasia (endometrial adenocarcinoma and poorly differentiated sarcoma). One cat survived long-term, while the other was suspected to have advanced metastatic disease and pulmonary metastasis on postoperative radiographs after developing respiratory distress. Diagnostic tests, including thoracic radiographs and abdominal ultrasound, should be considered when evaluating middle-aged to older queens suspected of pyometra to screen for evidence of neoplasia and to assess the extent of disease. Histopathological analysis of excised uterine tissue should be recommended to assess for uterine neoplasia in all cats with presumptive pyometra.

A 16-year-old boy attended the Emergency Department with sudden severe right iliac fossa pain and associated vomiting. He denied any urinary symptoms, diarrhoea or testicular pain. On examination, he had a locally tender right iliac fossa with guarding. External genitalia and testicular examination revealed an absent right testicle, the left testicle was not tender. The patient was haemodynamically stable. A clinical diagnosis of acute appendicitis and possible testicular torsion was made and the patient sent for an urgent diagnostic laparoscopy. At laparoscopy, the patient was found to have a torted, non-viable right-sided testicle in the abdominal cavity. On discussion with urology, a decision was made to excise the torted testicle as it was atrophic and had significant malignant potential. The appendix was normal. The patient made an unremarkable recovery and was discharged.

Abdominal Desmoid Tumor

A 45-year-old woman was found to have a pancreatic tumor by abdominal ultrasound performed for a medical check-up. Abdominal contrast-enhanced computed tomography showed a hypovascular tumor measuring 30 mm in diameter in the pancreatic tail. Endoscopic ultrasound-guided fine needle aspiration was performed. An extragastric growing gastrointestinal stromal tumor was thereby diagnosed preoperatively, and surgical resection was planned. Laparoscopic surgery was attempted but conversion to open surgery was necessitated by extensive adhesions, and distal pancreatectomy, splenectomy, and partial gastrectomy were performed. The histological diagnosis was an intra-abdominal desmoid tumor. A desmoid tumor is a fibrous soft tissue tumor arising in the fascia and musculoaponeurotic tissues. It usually occurs in the extremities and abdominal wall, and only rarely in the abdominal cavity. We experienced a case with an intra-abdominal desmoid tumor that was histologically diagnosed after laparotomy, which had been preoperatively diagnosed as an extragastric growing gastrointestinal stromal tumor. Although rare, desmoid tumors should be considered in the differential diagnosis of intra-abdominal tumors. Herein, we report this case with a literature review.
