Tumor maligno da bainha de nervo periférico em rim esquerdo de canino da raça whippet / Malignant tumor of the peripheral nerve sheath in a left whippet canine kidney

Background: Malignant tumors of the peripheral nerve sheath (MTPNS`s) are considered rare tumors that can affect soft tissues. In dogs, the occurrence is more common in the nerves of the brachial plexus, but they can affect the lumbosacral plexus and cranial nerves. Rarely, they can affect spinal nerves and nerve roots and the urinary tract, especially in kidneys. The present report aims to describe a clinical case of a 10-year-old sterilized female whippet, who had a history of persistent hematuria for months, with subsequent diagnosis of MTPNS as the cause of hematuria. Case: The patient came for evaluation with a history of persistent hematuria. Evaluation of abnormal elements and sedimentation, showed the description of numerous red blood cells and the presence of proteinuria. The abdominal ultrasound revealed a left kidney with enlarged dimensions, irregular contour, loss of corticomedullary definition. The urinary vesicle showed an increase in cellularity. On physical examination, the patient had vital parameters within the normal range. A Snap 4DX® Plus exam was requested, which showed a reaction for Dirofilaria immitis. With this result, it was initially suspected that renal vasculitis. After starting the treatment, the patient started to present normal colored urine. However, after the end of this period, the patient returned to hematuria. After six months of treatment and without justification for the permanence of hematuria, urethrocystoscopy was indicated, which revealed a urinary vesicle with a hemorrhagic focus. A urinary bladder wall biopsy was performed, which showed no changes. Four months after the urethrocystoscopic exam, the patient had her first azotemic crisis. This time that the left renal neoformation observed on ultrasound examination. With the discovery of the origin of the problem, a therapeutic approach could be instituted, consisting of the left...

Renal dysplasia in a Maltese dog

Background: Renal dysplasia (RD) is a common cause of renal failure in young dogs. It is defined as a disorganization inrenal parenchymal development, with abnormal differentiation. In all domestic animal species, RD may be hereditary oracquired. The affected animals show clinical signs of early chronic kidney disease, usually between 3 months to 3 yearsof age. The alterations include persistent metanephric ducts surrounded by primitive mesenchyme, glomeruli and fetaltubules, and abnormal interstitial fibrous tissue. We aimed to report the case of a 1-year-old canine with renal dysplasia.Case: A 1-year-old male Maltese dog experiencing polyuria, polydipsia, recurrent episodic vomiting, bloody diarrhea,weight loss, apathy, and anorexia was referred to a private clinic in the municipality of Itabuna-Bahia. Physical examination revealed hypochromic mucosa, dehydration estimated at 8%, rectal temperature of 37.5ºC, halitosis, and a bodyscore of 3 out of 9. Laboratory abnormalities included hematocrit of 18%, with hypochromic normocytic aregenerativeanemia, azotemia (urea - 530 mg/dL, creatinine - 10.5 mg/dL), hyperglobulinemia (4.7 g/dL), low urinary density (1005),proteinuria (300 mg/dL), and urinary pH - 7.0. Ultrasonography revealed bilateral small kidneys with loss of corticomedullary definition, cystic formations of different sizes on the renal surface, and hyperechoic areas in the parenchyma;these alterations were suggestive of bilateral chronic nephropathy. Considering the clinical, hematological, biochemical, andultrasonographic presentation associated with the age of the patient, renal dysplasia was suspected. The patient’s clinicalcondition progressed to loss of consciousness and convulsions, followed by death. Necropsy revealed pale, hypotrophickidneys with firm consistency, irregular capsular surface containing multiple cortical cysts of different sizes, and alteredcortico-medullar proportion. Kidney fragments were sent to...

Biochemical, endocrine, and histopathological profile of liver and kidneys of sheep with pregnancy toxemia / Perfil bioquímico, endócrino e histopatológico do fígado e rins de ovelhas com toxemia na prenhez

The objective of the present study was to characterize the biochemical, hormonal, and mineral profile, and histopathology of the liver and kidneys, related to the severity of natural cases of pregnancy toxemia (PT) in sheep. A total of 45 sheep with PT were analyzed at the "Clínica de Bovinos", Campus Garanhuns-UFRPE. The animals were submitted to clinical examination, followed by the collection of blood and urine. A necropsy was performed on thirteen animals that died and a histopathological examination was performed on samples of liver and kidneys. Increased creatinine, urea, glucose, fructosamine, non-esterified fatty acids, β-hydroxybutyrate, cortisol, chlorine, amylase, aspartate aminotransferase, gamma-glutamyltransferase, and folic acid were found, whereas insulin, potassium, and total and ionizable calcium presented low values for the species. Total protein, albumin, globulin, sodium, magnesium, and vitamin B12 remained within the normal range. In the macroscopic analysis of the liver, it was possible to observe an increase in organ and border size, yellowish coloration and parenchyma that varied from firm to friable. Vacuolation of the hepatocytes and renal tubular cells was observed. Metabolic disorders in sheep associated with hepatic and renal lesions are more apparent in overweight animals. With the greater impairment in hepatic and renal function, the clinical prognosis of animals with a high body score should be considered reserved.(AU)

Analisou-se 45 ovelhas na Clínica de Bovinos, Campus Garanhuns-UFRPE, com TP. Foram submetidas ao exame clínico, seguido de coleta de sangue e urina. Treze animais que vieram a óbito foram necropsiados, nas amostras de fígado e rins realizou-se exame histopatológico. Revelou-se elevação de creatinina, ureia, glicose, frutosamina, ácidos graxos não esterificados, β-hidroxibutirato, cortisol, cloro, amilase, aspartato aminotransferase, gama glutamiltransferase e ácido fólico, enquanto insulina, potássio, cálcio total e ionizável apresentaram valores abaixo para os da espécie. A proteína total, albumina, globulina, sódio, magnésio e vitamina B12 mantiveram-se dentro da normalidade. Na análise macroscópica do fígado, pôde-se observar aumento de tamanho do órgão e dos bordos, coloração amarelada e parênquima que variava de firme a friável. Observou-se vacuolização dos hepatócitos e das células tubulares renais. Os transtornos metabólicos nas ovelhas associados às lesões hepáticas e renais são mais aparentes nos animais com sobrepeso. Com o maior comprometimento da função hepática e renal, o prognóstico clínico dos animais com escore corporal elevado há de ser considerado reservado.(AU)

Papillary renal adenoma in a toco toucan (Ramphastos toco)

Primary renal neoplasms are infrequent in domestic animals and birds, being budgerigars an exception. This report describes a papillary renal adenoma in a toco toucan (Ramphastos toco), which was euthanized due to poor prognosis after surgical intervention of phalanx fractures in both wings. Grossly, the caudal pole of the right kidney had a nodular lesion measuring 3.5 x 1.7 x 1.5 cm. Microscopically, there was a well delimited neoplasm arranged in large and coalescent papillary structures composed by a single layer of epithelial cells. There was mild to moderate nuclear and cytoplasmic pleomorphism, whereas mitotic figures were absent. In conclusion, this tumor was considered as an accidental finding, which is similar to the majority of adenomas reported in domestic mammals.

Mammary adenocarcinoma with pulmonary, hepatic and renal metastasis in a chinchilla (Chinchilla laniger)

Background: Chinchillas are small, long-lived hystricomorph rodents closely related to guinea pigs, porcupines and agoutis. Used extensively in scientific research and fur production, its use as a pet has grown exponentially in the last decade, increasing their presence in veterinary clinics and hospitals. The most common health conditions for chinchillas kept as pets are a result of husbandry or dietary deficiencies, and they rarely develop neoplasia. Although rare, neoplasias do occur in these animals and should be included as differential diagnosis. This report describes the occurrence of mammary adenocarcinoma in a companion chinchilla with several metastatic foci in lungs, liver and kidneys.Case: A 6-year-old female chinchilla (Chinchilla laniger) was presented with progressive hyporexia, apathy and a volume increase in the right axillary region. Since the owner noted purulent secretion in the ulcerated mass, he began treatment, without veterinarian consent, using topic rifampicin, 0.5 mL dipyrone sodium oral and 1.5 mL of enrofloxacin. All of which were used orally, once a day, for five days. On presentation at the veterinary hospital, the animal was poorly responsive, mildly dehydrated and had moderate body condition. Physical examination revealed pale mucous membranes, body temperature of 36.4°C and an increased volume, soft upon palpation, near inguinal area. The mass in the right axillary region was adhered, soft and ulcerated. A fine-needle aspiration was performed and the animal was sent home with instructions to perform forced feeding until the citology results were obtained, which were inconclusive. At the owners request, no other diagnostic tests were performed. Six days after initial examination the animal lost 5% of its body weight as anorexy, lethargy and locomotion difficulties progressed, at which point the owner requested euthanasia. The animal was sent for postmortem examination.[...](AU)

Effects of remote ischemic preconditioning and topical hypothermia in renal ischemia-reperfusion injury in rats

Purpose:To evaluate whether combining hypothermia and remote ischemic preconditioning (RIPC) results in protection from ischemia-reperfusion (IR). Methods: Thirty-two Wistar rats underwent right nephrectomy and were randomly assigned to four experimental protocols on the left kidney: warm ischemia (group 1), cold ischemia (group 2), RIPC followed by warm ischemia (group 3), and RIPC followed by cold ischemia (group 4). After 240 minutes of reperfusion, histological changes in the left kidney, as well as lipid peroxidation and antioxidant enzyme activity, were analyzed. The right kidney was used as the control. Serum creatinine was collected before and after the procedures. Results: RIPC combined with hypothermia during IR experiments revealed no differences on interventional groups regarding histological changes (p=0.722). Oxidative stress showed no significant variations among the groups. Lower serum creatinine at the end of the procedure was seen in animals exposed to hypothermia (p 0.001). Conclusions: Combination of RIPC and local hypothermia provides no renal protection in IR injury. Hypothermia preserves renal function during ischemic events. Furthermore, RIPC followed by warm IR did not show benefits compared to warm IR alone or controls in our experimental protocol.(AU)

Perinephric pseudocyst in a two-month-old female cat

Background: Perinephric pseudocyst is defined as an accumulation of fluid in fibrous sacs surrounding one or both kidneys, and may be located in the subcapsular or extracapsular region. Histologically, it is characterized by the absence of an epithelial lining to the cyst wall and the term pseudocyst is used. This condition have been reported sporadically in cats, and is associated with chronic kidney disease, mainly in older animals. The diagnosis is based on imaging tests and the prognosis is related to the severity of renal dysfunction. The aim of this report is to describe an unusual presentation of perinephric pseudocyst in a very young female cat.Case: A mixed-breed 2-month-old female cat was evaluated for presenting abdominal distension and anatomical deformities of the limbs. Renomegaly on the left side was noted during abdominal palpation. On presentation, the serum creatinine was 134 µmol/L. Urinalysis showed mild proteinuria, presence of squamous and transitional cells, and rare bacteria. The urine specific gravity was 1.044 and urine protein to creatinine ratio was 0.23. Abdominal ultrasonography revealed a large anechoic subcapsular cyst on the left kidney, in adittion to dilatation of renal pelvis and calyces. The excretory urography showed left renomegaly, and the nephrogram and pyelogram were not clearly observed in this kidney, indicating unilateral deficiency in renal filtration. The cat was referred to unilateral left nephrectomy but died shortly before surgery. At necropsy, marked left kidney enlargment was observed (6.5 x 4.5 x 1.5 cm), with a cystic aspect, occupying almost the entire abdominal cavity. The cystic content was translucent and was compressing the renal parenchyma, resulting in hydronephrosis. The capsule forming the cyst wall was composed of connective tissue, characterizing the perinephric pseudocyst.Discussion: Reports show cases of perinephric pseudocyst affecting mostly older animals, above eight years old.[...]

Intermittent hemodialysis in dogs with chronic kidney disease stage III / Hemodiálise intermitente em cães com doença renal crônica III

Intermittent hemodialysis (IHD) is a form of renal replacement that is used in veterinary medicine for cases involving drug removal, electrolyte imbalance, acute kidney injury, and chronic kidney disease (CKD). The aim of the present study was to verify the efficacy of IHD in dogs with CKD staged at grade III and to evaluate the effect of IHD on quality of life. Twelve dogs with CKD at stage III met the inclusion criteria and were divided equally into two groups. The control group (n=6) received only clinical treatment and intravenous fluid therapy, and the hemodialysis group (n=6) received clinical and IHD treatments. Blood samples were collected before and after treatments in both groups. We evaluated complications and clinical parameters of IHD every 30 minutes. Hemodialysis decreased serum urea, creatinine, and phosphorus. Despite the evident removal of nitrogen compounds, dialysis treatment did not increase survival time in these patients. The results of this study do not support the early use of dialysis in dogs with chronic kidney disease stage III.

A Hemodiálise Intermitente (HDI) é uma modalidade de substituição renal, utilizada na veterinária nos casos de remoção de drogas, distúrbios hidroeletrolítico, lesão renal aguda e doença renal crônica (DRC). O objetivo do presente estudo foi estudar o efeito da hemodiálise intermitente em cães com DRC estadeados no grau III, visando avaliar a qualidade de vida. Foram selecionados 12 cães com DRC no estádio III pelos critérios de inclusão, após foram divididos em Grupo Controle (n=6), onde foi preconizado apenas tratamento clínico e fluidoterapia, e Grupo hemodiálise (n=6), que além do tratamento clínico, utilizou-se a hemodiálise intermitente. A colheita de sangue para avaliação laboratorial foi realizada antes e após a fluidoterapia de ambos os grupos. Foram avaliados as intercorrências e os parâmetros clínicos durante a HDI a cada 30 minutos. A instituição do tratamento dialítico promoveu uma eficaz diminuição das concentrações séricas de ureia, creatinina e fósforo de modo mais precoce. Apesar da evidente remoção dos compostos nitrogenados, o tratamento dialítico não aumentou a sobrevida destes pacientes, não justificando o emprego desta técnica de forma precoce em cães com doença renal crônica no estádio III.

Occurrence of Paratanaisia confusa Freitas, 1951 in free-living guira cuckoo (Guira guira, Cuculiformes: Crotophagidae) / Ocorrência de Paratanaisia confusa Freitas, 1951 em anu-branco de vida livre (Guira guira, Cuculiformes: Crotophagidae)

This report presents a description of natural infection of an adult free-living guira cuckoo with Paratanaisia confusa. Histological and morphological evaluations of renal and parasite samples were performed. The morphological analysis of the parasites revealed spiny tegument, characteristic of P. confusa helminthes. Although macroscopic alterations were absent in the kidneys, the histopathology revealed parasites inside the collecting ducts causing dilatation and destruction of the lining epithelial cells in addition to small focal inflammatory infiltrates in the renal parenchyma. However, as the bird was free-living and naturally infected it was not possible to confirm if all these alterations were directly caused by the parasite presence or if they were related to causes other than the parasitism. Nonetheless, such findings indicate that these trematodes may have pathogenic potential in this host.(AU)

A infecção de um anu-branco, de vida livre, por Paratanaisia confusa é descrita. Avaliações histológicas e morfológicas de amostras renais e dos parasitas foram realizadas. A análise morfológica dos parasitas revelou a presença de tegumento espinhoso, que é característico de P. confusa. Embora alterações renais macroscópicas estivessem ausentes, a histopatologia revelou a presença de parasitas no interior de ductos coletores, provocando dilatação destes e destruição das células epiteliais, além de discretos infiltrados inflamatórios focais no parênquima renal. Entretanto, como a ave era proveniente de vida livre e naturalmente infectada, não foi possível confirmar se todas as alterações observadas foram diretamente provocadas pela presença dos parasitas, ou se estavam relacionadas a outras causas. Todavia, esses achados indicam que os trematódeos dessa espécie possam ter potencial patogênico no hospedeiro estudado.(AU)

Renal histopathological changes in dogs naturally infected with Ehrlichia canis

Renal involvement in Canine Monocytic Ehrlichiosis (CME) has been demonstrated in chronic cases without histopathological classification of patterns of glomerulopathy. Thus, in this study we proposed to evaluate the histopathological pattern, focusing on the types of glomerulonephritis in kidneys of dogs naturally infected with Ehrlichia canis.Twelve dogs naturally infected with E. canis and six healthy dogs were used. After clinical evaluation and diagnostic confirmation, the animals were euthanized and kidney fragments were obtained for histopathological examination, including hematoxylin and eosin (HE), Massons trichrome, periodic acid-Schiff (PAS), periodic acid-methenamine silver (PAMS) and Congo red stain. Histopathological analysis of dogs with CME demonstrated that major lesions were present in the glomerulus and tubulointerstitial region in 100% of cases. The type of glomerular injury was membranoproliferative in 83.33%, and proliferative in 16.67%. Interstitial nephritis was present in the cortical region of all infected dogs. Minimal to marked lymphohistioplasmacytic inflammatory infiltrate was present in the interstitial, perivascular and periglomerular areas. Differential count of inflammatory cells indicated that lymphocytes predominated in comparison to plasma cells and histiocytes. Interstitial fibrosis and hyaline casts of lower intensity were observed. There was a negative correlation between serum albumin levels and severity of glomerulopathy. In conclusion, membranoproliferative glomerulopathy and interstitial nephritis are the major renal lesions in CME. It has been suggested that the presence of inflammatory infiltrates rich inlymphocytes indicates participation of these infiltrates in the immunopathogenesis of renal lesion in dogs with CME. Furthermore, hypoalbuminemia also seems be a marker of renal damage in dogs infected with E. canis.

Estudo retrospectivo das causas de condenações de rins de suínos abatidos em matadouro-frigorífico de Sinop, MT 2008-2013 / Retrospective study of swine kidney condemnations in slaughterhouse from Sinop, Mato Grosso state 2008-2013

This study aimed to identify the main reasons for renal condemnation in a swine slaughterhouse. Data from the State Inspection Service from this industry located in Sinop, Mato Grosso State, in the period from January 2008 to December 2013, were used. A total of 415,312 pigs coming from municipalities located in the region were inspected. From these, 244,730 animals had some sort of postmortem condemnation. The main causes for condemnation (total and partial) were grouped according to the largest number of condemnations. The most frequent causes of condemnation were nephritis (37.78%), urinay cysts (18.68%) and uronephrosis (2.11%).

Foram inspecionados 415.312 animais, procedentes de municípios localizados na região médio-norte matogrossense. Dessas, 244.730 tiveram algum tipo de condenação post mortem. As principais causas de condenação (total e parcial) foram agrupadas segundo o maior número das condenações. As causas de condenação mais frequentes foram nefrite (37,78%), quisto urinário (18,68%) e uronefrose (2,11%).

Estudo retrospectivo das causas de condenações de rins de suínos abatidos em matadouro-frigorífico de Sinop, MT 2008-2013 / Retrospective study of swine kidney condemnations in slaughterhouse from Sinop, Mato Grosso state 2008-2013

This study aimed to identify the main reasons for renal condemnation in a swine slaughterhouse. Data from the State Inspection Service from this industry located in Sinop, Mato Grosso State, in the period from January 2008 to December 2013, were used. A total of 415,312 pigs coming from municipalities located in the region were inspected. From these, 244,730 animals had some sort of postmortem condemnation. The main causes for condemnation (total and partial) were grouped according to the largest number of condemnations. The most frequent causes of condemnation were nephritis (37.78%), urinay cysts (18.68%) and uronephrosis (2.11%).(AU)

Renal histopathological changes in dogs naturally infected with Ehrlichia canis

Renal involvement in Canine Monocytic Ehrlichiosis (CME) has been demonstrated in chronic cases without histopathological classification of patterns of glomerulopathy. Thus, in this study we proposed to evaluate the histopathological pattern, focusing on the types of glomerulonephritis in kidneys of dogs naturally infected with Ehrlichia canis.Twelve dogs naturally infected with E. canis and six healthy dogs were used. After clinical evaluation and diagnostic confirmation, the animals were euthanized and kidney fragments were obtained for histopathological examination, including hematoxylin and eosin (HE), Massons trichrome, periodic acid-Schiff (PAS), periodic acid-methenamine silver (PAMS) and Congo red stain. Histopathological analysis of dogs with CME demonstrated that major lesions were present in the glomerulus and tubulointerstitial region in 100% of cases. The type of glomerular injury was membranoproliferative in 83.33%, and proliferative in 16.67%. Interstitial nephritis was present in the cortical region of all infected dogs. Minimal to marked lymphohistioplasmacytic inflammatory infiltrate was present in the interstitial, perivascular and periglomerular areas. Differential count of inflammatory cells indicated that lymphocytes predominated in comparison to plasma cells and histiocytes. Interstitial fibrosis and hyaline casts of lower intensity were observed. There was a negative correlation between serum albumin levels and severity of glomerulopathy. In conclusion, membranoproliferative glomerulopathy and interstitial nephritis are the major renal lesions in CME. It has been suggested that the presence of inflammatory infiltrates rich inlymphocytes indicates participation of these infiltrates in the immunopathogenesis of renal lesion in dogs with CME. Furthermore, hypoalbuminemia also seems be a marker of renal damage in dogs infected with E. canis.(AU)
