Ovarian papillary carcinoma in a Mongolian gerbil (Meriones unguiculatus)

Neoplasms are among the most impacting disease diagnoses in veterinary medicine and have become increasingly common due to the greater longevity of animals as living conditions improved. The Mongolian gerbil is a small rodent species that has become popular recently. In these animals, the occurrence of neoplastic processes is relatively common, mainly tumors of the ventral gland in males and ovarian tumors in females. This work aims to report an ovarian tumor in a Mongolian gerbil Meriones unguiculatus Milne-Edwards 1867 (Rodentia, Muridae). At the initial presentation, the animal had dyspnea, prostration, and increased abdominal volume in the topography of the right ovary of approximately 2 cm. The animal was submitted to exploratory laparotomy because of the emergency nature of the case and the owners' refusal of additional exams due to financial restrictions. Thus, an ovariohysterectomy was performed, followed by a histopathological examination. The histopathology revealed an ovarian papillary carcinoma affecting both ovaries and cystic endometrial hyperplasia. With surgical removal and drainage of the thoracic fluid, the animal showed good recovery, with general improvement and return to regular activity, with a life expectancy of two years. Currently, the demand for specialized veterinarians for unconventional pets is increasing. This condition allows owners to raise their animals more properly, favoring greater longevity. Knowledge about the prevalence and incidence of diseases in different species is of enormous relevance in establishing the appropriate therapy, improving life quality, and increasing life expectancy in animals' lives.(AU)

Comparison of urinary protein-to-creatinine ration, serum albumin, serum creatinine and systolic arterial blood pressure of glomerular injury cases in dogs with chronic kidney disease / Comparação da razão proteína creatinina urinárias, albumina sérica, creatinina sérica e pressão arterial sistólica das lesões glomerulares encontradas em cães com doença renal crônica

This study aims at assessing the prevalence of glomerular alterations in dogs with chronic kidney disease (CKD) and comparing the clinical and laboratory parameters. The tests conducted include a double-blind histopathological assay conducted by two pathologists, urine tests including inactive sediment, urinary protein-to-creatinine (UPC), serum albumin and serum creatinine, as well as measurement of the systolic arterial blood pressure. The prevalence of glomerular injuries was determined and the predominant injury was compared with a group comprised of the remaining injuries. The study included 24 dogs with CKD. The results revealed a predominance of membranous glomerular alterations 17/24 (70,83%), followed by glomerulosclerosis 3/24 (12,50%), membranoproliferative injuries 2/24, glomerulocystic atrophy 1/24 and glomerular amyloidosis 1/24. Amyloidosis presented the highest UPC while the membranoproliferative injury presented the lowest mean concentration of serum albumin. Higher values in the UPC did not correspond with lower mean serum albumin values. Glomerulosclerosis presented the highest mean systolic blood pressure and glomerular atrophy presented the highest creatinine values. When comparing membranous injuries with a group comprised of the remaining injuries, the UPC did not present significant differences between the groups. Renal amyloidosis was included in the group with the lowest systolic arterial blood pressure values while membranoproliferative injury was included in the group with highest UPC. The group called "others" presented the highest creatinine value. Dogs with CKD may present several types of glomerular injuries with similar clinical and laboratory profiles. This study observed a predominance of membranous glomerular injuries, followed by membranoproliferative injuries, glomerulocystic atrophy and amyloidosis.(AU)

O estudo teve como objetivo avaliar a prevalência das alterações glomerulares dos cães doentes renais crônicos e comparar parâmetros clínicos e laboratoriais. Foi realizada análise histopatológica por dois patologistas pelo método duplo-cego, análise dos exames de urina com sedimento inativo, razão proteína creatinina urinárias, avaliação da creatinina e albumina séricas e pressão arterial sistólica. Determinouse a prevalência das lesões glomerulares e foi comparado o grupo de lesões predominante com um grupo abrangendo as demais lesões. Foram incluídos neste estudo 24 cães doentes renais crônicos. Após análise foi observado predomínio de alterações glomerulares membranosas (n=17), seguidos de glomeruloesclerose (n=3), lesões membranoproliferativas (n=2), atrofia glomerulocística (n=1) e amiloidose glomerular (n=1). A amiloidose apresentou maior razão proteína creatinina urinárias e a lesão membranoproliferativa obteve a menor média de albumina sérica. Maiores valores da razão proteína creatinina urinárias não corresponderam com menor média de albumina sérica. Glomeruloesclerose teve maior média de pressão arterial sistólica. O maior valor de creatinina foi observado no caso de atrofia glomerular. Quando comparados lesões membranosas com um grupo dos demais tipos de lesões, RPC não diferiu entre os grupos. Amiloidose renal estava inclusa no grupo de animais com valores mais baixos de pressão arterial sistólica e a lesão membranoproliferativa estava entre os animais com maior RPC. O grupo denominado "outros" teve maior valor de creatinina. Cães com doença renal crônica podem apresentar diferentes tipos de lesões glomerulares com quadros clínicos e laboratoriais semelhantes. Há um predomínio de lesões glomerulares membranosas, seguidas pela glomeruloesclerose, lesão membranoproliferativa, atrofia glomerulocística e amiloidose.(AU)

Intermittent hemodialysis, an alternative treatment for ovine with acute-on-chronic kidney disease / Hemodiálise intermitente, um tratamento alternativo para ovinos em doença renal crônica agudizada / Hemodialisis intermitente, un tratamiento alternativo para ovinoscon enfermedad renal aguda en crónica

Chronic Kidney Disease (CKD) is a syndrome composed of numerous comorbidities such as the failure of excretion of toxins and nitrogenous compounds from metabolism, as well as the failure to maintain endocrine, water, electrolyte and acid-base homeostasis in all mammals. As it is a non-regenerative and progressive disease, any endogenous or exogenous insults in the organ in question will lead to the intensification of all these mentioned disorders associated with decreased urinary output. Several studies in humans and animals recommend the use of renal replacement therapy, especially in those who already have CKD, and who are in uremic syndrome. This report aims to demonstrate that the use of intermittent hemodialysis (HI) in sheep is a therapeutic alternative in those in renal failure. A six-year-old Bergamasca sheep was presented with lateral decubitus, dyspnea, dark liquid diarrhea, apathy, anorexia and pulmonary crepitation on auscultation. Laboratory tests showed azotemia and electrolyte changes such as hypocalcemia, hypokalemia, hypochloremia, isosthenuria (1,012), pyuria, glycosuria, and a protein: creatinine ratio of 0.88. In ultrasonography, the real resistivity index was above 0.54, being suggestive of loss of renal perfusion. The treatment chosen consisted of electrolytic and fluid replacement, associated with HI. After HI, the sheep showed great clinical and laboratory improvement as expected, however, despite not having survived, the histopathological findings of the necropsy pointed out segments of glomerulosclerosis, thus reinforcing the hypothesis that the animal already had a CKD which was aggravated due to the association of hypovolemia, hypotension by anesthetic drugs and the indiscriminate use of NSAIDs. Despite the death of the sheep, HI again proved to be a therapy of rapid clinical...

A Doença Renal Crônica (DRC) é uma síndrome composta por inúmeras comorbidades como a falha da excreção de toxinas e compostos nitrogenados oriundos do metabolismo, bem como da falha na manutenção da homeostase endócrina, hídrica, eletrolítica e ácido-básico de todos os mamíferos. Por ser uma doença não-regenerativa e progressiva, quaisquer insultos endógenos ou exógenos no órgão em questão propiciará a intensificação de todas estas desordens mencionadas associadas a diminuição do débito urinário. Diversos estudos em humanos e animais recomendam o emprego de terapia de substituição renal, especialmente naqueles que já apresentam a DRC, e que se encontram em síndrome urêmica. Este relato tem como objetivo demonstrar que o emprego da hemodiálise intermitente (HI) em ovinos é uma alternativa terapêutica naqueles em falência renal. Uma ovelha Bergamácia de seis anos foi encaminhada em decúbito lateral, dispneia, diarreia líquida escura, apatia, anorexia e crepitação pulmonar à auscultação. Exames laboratoriais demonstraram azotemia e alterações eletrolíticas como hipocalcemia, hipocalemia, hipocloremia, isostenúria (1.012), piúria, glicosúria, e razão proteína: creatinina de 0,88. Em ultrassonografia, o index de resistividade real, apresentou-se acima de 0,54, sendo sugestivo de perda de perfusão renal. O tratamento eleito constituiu na reposição eletrolítica e volêmica, associada a HI. Após a HI, a ovelha apresentou grande melhora clínica e laboratorial como esperado, no entanto, apesar de não ter sobrevivido, os achados histopatológicos da necropsia apontaram segmentos de glomeruloesclerose, reforçando assim a hipótese de que o animal já apresentava uma DRC a qual agudizou devido a associação da hipovolemia, hipotensão por fármacos anestésicos e ao uso indiscriminado de AINES. Apesar do óbito da ovelha, a HI demonstrou novamente ser uma terapia de rápida melhora clínica e laboratorial do paciente comparada ao tratamento clínico convencional, assim sendo uma importante alternativa...

Ovarian torsion in a primipara female dog in Brazil

Background: Ovarian torsion is a condition which the ovary and the ovarian pedicle twist around the ovary suspensory ligament. No report regarding this condition was reported. The aim of the report was to describe a case of unilateral ovarian torsion in a 2-year-old primipara Golden Retriever dog.Case: A 2-year-old female primipara Golden Retriever dog weighting was referred to the Veterinary Hospital, for purulent vaginal discharge evaluation. The dog was presenting anorexia, weight loss, and intermittent diarrhea and vomiting. A cesarean section was performed nine months before her presentation and the oestrus cycle was recorded six months after the cesarean section. Discomfort was observed during the palpation of the abdomen and purulent vaginal was observed. Vaginal swab was performed and followed by cytological examination. The ultrasonographic examination was consistent with pyometra. The ovariohysterectomy was performed and were observed torsion of the left ovary. The histopathological examination of the left ovary and uterus were consistent with ovary necrosis and pyometra. Ten days after surgery the vaginal discharge had resolved and the sutures were removed. Six months postoperatively the dog revealed no further abnormalities. Grossly, the left ovary had firm consistency, dark red surface and 8 cm diameter. The histopathology examination findings were consistent with a diagnosis of diffuse necrosis of left ovary due to ovarian torsion, and uterine suppurative inflammatory process - pyometra.Discussion: Ovarian torsion is uncommon in small animals, but can be observed high incidence in pregnant female dogs than in non-pregnant ones. The 360º an asynchronous ovarian torsion described in the present case is also an unusual condition in primipara female dogs due to the smaller stretching of the ovary suspensory ligament. The ovarian torsion is considerate an emergency condition due to acute abdominal pain.[...]

Femoral diaphyseal fractures fixation technique using an adjustable nylon tie in dog (Canis lupus familiaris) and cat (Felis catus domesticus)

Background: Adjustable nylon ties polyamide 6.6 is devices produced from the same material of surgical nylon wire and have been used in different surgical procedures in small animals and in human patient. Reports regarding the use of these devices as secondary fixation technique of femoral diaphyseal fractures in animals are rare in the literature. The aim of the present report case was to describe the use of adjustable nylon tie polyamide 6.6 as secondary fixation technique in a 3-year-old dog and 4-month-old cat, diagnosed with femoral diaphyseal fractures.Cases: Case 1. A 3-year-old female dog was presented with reluctance to support the left hind limb, with 5 days’ duration. Pain and edema on the left femoral diaphyseal region was identified. The limb was submitted to radiographic exam and revealed a closed, complete and comminuted fracture of the diaphysis of the femur, and was decided to perform a surgical stabilization by open reduction through primary fixation with intramedullary pin, and secondary fixation of bone fragments with adjustable nylon ties polyamide 6.6, as a substitute of steel cerclage wire. The bone fragments were alignment and fixated with five polyamide nylon ties. The excess was removed with a scalpel blade along the lock. Seven days after surgery the skin sutures were removed and were observed reluctance to support the left hind limb. Physiotherapy sessions were prescribed. Forty days after the surgery was performed a radiographic exam of the left hind limb which revealed alignment of the bone axis. Six months after the surgery, the owner reported that the dog supported the left hind limb. Case 2. A 4-month-old female cat was presented with history of trauma, with 24 h’s duration, and reluctance in supporting the left hind limb. On physical examination there was identified pain on the left femoral diaphyseal region.[...]
