Follicular cystitis in a dog: first case report described in Brazil / Cistite folicular em cão: primeiro relato de caso descrito no Brasil

A 2-year-old English bulldog presented history of recurrent lower urinary tract disease, refractory to treatment. The Complete Blood Count revealed lymphopenia, hyperproteinemia, and hyperglobulinemia, while urinalysis indicated leukocyturia and bacteriuria. On the abdominal ultrasound, the bladder had a focal wall thickening in its cranial portion, as well as irregular echogenicity and internal margins. A bladder surgical biopsy was performed, indicating the presence of follicular cystitis. Clinical signs disappeared after treatment with a combination of amoxicillin and clavulanic acid, NSAIDs, supplementation with cranberry extract associated with cat's claw (Uncaria tomentosa). Clinical follow-up 12 months after surgery showed remission at all clinical signs. Follicular cystitis in dogs was reported only once worldwide, this case report is the first in Brazil; thus, it may be considered in the differential diagnosis for patients with refractory and recurrent lower urinary tract disease.

Um Bulldog Inglês de 2 anos apresentou história clínica de doença recorrente do trato urinário inferior, refratária ao tratamento. O hemograma revelou uma discreta linfopenia, hiperproteinemia e hiperglobulinemia. Já a urinálise apontou leucocitúria e bacteriúria. Na ultrassonografia, a bexiga apresentava espessamento focal da parede da bexiga em porção cranial, ecogênica e margens internas irregulares. A biópsia cirúrgica da bexiga foi compatível com cistite folicular. Os sinais clínicos desapareceram após o tratamento com uma combinação de amoxicilina - ácido clavulânico, AINEs, suplementação alimentar de extrato de cranberry associado a unha de gato (fitoterápico da planta Uncaria tomentosa). O acompanhamento, 12 meses após a cirurgia, confirmou que o cão estava livre de sinais clínicos. A cistite folicular foi relatada apenas em 1 cão no mundo, sendo esse considerado o primeiro relato no Brasil. Essa enfermidade deve ser considerada um diferencial para pacientes com doença refratária do trato urinário inferior de longa data.

Effects of multimodal environmental modification in crystal-related feline lower urinary tract diseases / Efeitos da modificação ambiental multimodal em felinos com cristais doenças do trato urinário inferior relacionadas a cristais

This study aims to analyze the effects of multimodal environmental modification (MEMO) of cats with recurrence of lower urinary tract signs (LUTS). Treatment of FLUTD included pharmacological treatment, dietary management, and multimodal environmental modification approaches. Twenty client-owned indoor-housed cats with recurrence of lower urinary tract signs had been covered in this observation. Diagnosis of lower urinary tract was made primarily based on the cat's clinical signs, results of laboratory parameters, urinalysis and ultrasonographic examination. Cats were divided into two groups as cefovecin (8 mg/kg sc, single time use) + meloxicam (0.1mg/kg q24h, 3 days) + dry food including l-tryptophan and milk protein hydrolysate to dissolve struvite stones (Group 1) and cefovecin + meloxicam + dry food including l-tryptophan and milk protein hydrolysate to dissolve struvite stones + multimodal environmental modification (Group 2). Clinical and urinary parameters are scored as 0, 1, 2, 3 or 4 points on initial, third, seventh days. Scores of clinical parameters were significantly different between (p<0.05) group 2 and group 1 on the third and seventh days and scores of urinary parameters are significantly different between (p<0.05) group 2 than group 1 on the seventh day. Clients who were contacted after 1 year reported that they did not see any clinical signs of urinary tract diseases.

Este estudo tem como objetivo avaliar os efeitos da modificação ambiental multimodal (MEMO) em gatos com recorrência de sinais do trato urinário inferior (LUTS). O tratamento da FLUTD incluiu tratamento farmacológico, controle dietético e abordagens de modificação ambiental multimodal. Vinte gatos de propriedade de clientes, alojados em ambientes fechados, com recorrência de sinais do trato urinário inferior foram incluídos nessa observação. O diagnóstico do trato urinário inferior foi feito principalmente com base nos sinais clínicos do gato, nos resultados dos parâmetros laboratoriais, na urinálise e no exame ultrassonográfico. Os gatos foram divididos em dois grupos: cefovecina (8 mg/kg sc, uso único) + meloxicam (0,1mg/kg q24h, 3 dias) + ração seca incluindo l-triptofano e hidrolisado de proteína do leite para dissolver cálculos de estruvita (Grupo 1) e cefovecina + meloxicam + ração seca incluindo l-triptofano e hidrolisado de proteína do leite para dissolver cálculos de estruvita + modificação ambiental multimodal (Grupo 2). Os parâmetros clínicos e urinários foram pontuados como 0, 1, 2, 3 ou 4 pontos no primeiro, terceiro e sétimo dias. As pontuações dos parâmetros clínicos foram significativamente diferentes entre (p<0,05) o grupo 2 e o grupo 1 no terceiro e sétimo dias, e as pontuações dos parâmetros urinários foram significativamente diferentes entre (p<0,05) o grupo 2 e o grupo 1 no sétimo dia. Os clientes que foram contatados após um ano relataram que não observaram nenhum sinal clínico de doenças do trato urinário.

Urethral obstruction due to seminal vesiculitis in a sheep: case report / Obstrução uretral por vesiculite seminal em ovino: relato de caso

We report a case of urethral obstruction due to seminal vesiculitis in a Dorper sheep, with symptoms of anuria, rectal prolapse, orchitis/epididymitis, and uroperitoneum and biochemical tests indicating severe azotemia. The animal died due to advanced azotemia, and necropsy revealed kidneys with cortical and medullary necrosis, pyelonephritis of renal calyces, hydronephrosis, ruptured and necrotic bladder, and vesicular, bulbourethral, and ampoule accessory sex glands. There was prostate hyperplasia that revealed a large amount of pus in the cross section, which was also observed bilaterally in the epididymis and right testis. Morphotintorial and biochemical analyses of bacteria obtained from microbiological culture revealed Corynebacterium sp. and Escherichia coli. Infection, hyperplasia, and abscessation of accessory sex glands caused urethral compression, resulting in an obstructive condition, similar to urolithiasis, in addition to bacteremia. Hyperplastic seminal vesiculitis, although rare, must be included among the differential diagnoses of obstructive processes in the urinary tract of sheep.

Relata-se um caso de obstrução uretral decorrente de vesiculite seminal em carneiro da raça Dorper, com quadro de anúria, prolapso retal, orquite/epididimite e uroperitôneo, com exames bioquímicos indicativos de severa azotemia. Devido ao quadro avançado de azotemia, o animal faleceu e, na necropsia, foi observado:: rins com necrose de cortical e medular, pielonefrite dos cálices renais e hidronefrose, bexiga rompida e necrosada, assim como glândulas sexuais acessórias vesiculares, bulbouretrais e ampola. Havia hiperplasia de próstata que, ao corte transversal, revelou grande quantidade de pus, que também foi observado bilateralmente no epidídimo e no testículo direito. As análises morfotintoriais e bioquímicas das bactérias obtidas a partir do cultivo microbiológico foram compatíveis com Corynebacterium sp. e Escherichia coli. A infecção, a hiperplasia e a abscedação das glândulas sexuais acessória, causaram compressão uretral, levando a um quadro obstrutivo, semelhante à urolitíase, somado à bacteremia. A vesiculite seminal hiperplásica, apesar de rara, deve ser incluída entre os diagnósticos diferenciais dos processos obstrutivos do trato urinário de carneiros.

Leptospira spp. of the urinary tract of female carrier goats in semi-arid conditions

Background: Leptospirosis is an important infectious disease in goat farming, with a worldwide distribution. It is usually transmitted by rodents and the genital route, may cause reproductive losses, negatively impacting goat farming. The diagnosis lies on serological, molecular and isolation techniques. Considering the importance of this disease for small ruminants, this work aimed to evaluate the serological, molecular findings and isolation of pathogenic leptospires in the urinary tract (kidney and bladder tissues) of goats. Materials, Methods & Results: Thirty-four adult goats were used for slaughter. Renal samples (n = 34), bladder (n = 34), were collected for isolation of the agent and molecular detection of Leptospira sp. and blood samples (n = 34) for serological testing. The polymerase chain reaction (PCR) was used as a molecular test and the microscopic serum agglutination test (MAT) was used as a serological test. Samples with DNA amplification were subjected to genetic sequencing. The presence of Leptospira DNA was found in the tissues of 8 (23.4%) goats, and of these, only 2 were positive in PCR and MAT. There was a slight agreement between the PCR and MAT techniques (k = 0.150; P = 0.436). In 6 (17.6%) samples of renal tissue and 2 (5.8%) bladder samples, Leptospira DNA was detected. The genes in a kidney tissue sample were sequenced and demonstrated 99% similarity to Leptospira interrogans. Anti-Leptospira sp. were detected in 6 (17.6%) of the animals tested. Discussion: Serology identified 3 predominant serogroups: Icterohaemorrhagiae, Tarassovi and Autumnalis, serogroups that are related to the presence of rodents that coexist in rural environments. Autumnalis has been reported in small ruminants, raising the hypothesis that goats are adapted, becoming chronic carriers and possible maintenance hosts. The frequency obtained (17.6%) may be the result of the mixed breed pattern and rustic characteristics inherent to the goat species. Given the characteristics of the semi-arid region, such as low rainfall and high solar incidence, it is essential to use an adapted methodology, with a lower cut-off point (1:50), as the serological titer is an established relationship between the animal species, the level of exposure throughout its evolution and the region studied. Molecular findings and bacterial isolation reveal the agent's ability to colonize the urinary tract of goats. These data show the importance that urine has in the epidemiological chain, being able to transmit the agent through direct contact with this product or through contamination of soil and water. There was no statistical agreement between the diagnostic techniques used in this study, in this case, an association between PCR and MAT is recommended to obtain data with high sensitivity and specificity. A bladder sample was sequenced and showed 99% similarity to Leptospira interrogans. In the semiarid region, the most common form of leptospirosis spread is through the sale of animals in business fairs for breeding, rearing or slaughter, as well as sharing the same property with several breeders. The introduction of chronic and asymptomatic carriers on the properties represents a serious risk for the spread of the disease. The results show the presence of Leptospira spp. in semi-arid goat herds, having as risk factors the presence of rodents and intercropping. The association of MAT and PCR is necessary for a better diagnosis of the disease.

Crystallurical profile in sheep after ammonium chloride supplementation / [Perfil cristalúrico em ovinos suplementados com cloreto de amônio]

Although urinary crystals are habitual components, urolithiasis formation is always preceded by these concretions. We aimed to identify the change in the crystalline profile in sheep supplemented with ammonium chloride. Twenty-five male sheep aged three months, feedlot and randomly distributed into three groups were used: Control Group (CG) n = 5 did not receive Ammonium Chloride; G200 Group (n=10) (200mg/kg) of Ammonium Chloride for 56 consecutive days; G500 Group (n=10) (500mg/kg) of Ammonium Chloride for 56 consecutive days, administered daily orally. Sampling times and clinical evaluation were performed at seven days, with M0 (immediately before Ammonium Chloride), M1 (seven days after) until M8, totaling 70 days of feedlot. Urine samples were performed to identify the presence, type, and quantity of crystals. There was an increase in crystalluria in all groups in relation to time due to dietary influence, mainly in the CG, which presented more crystals of amorphous calcium phosphate and calcium oxalate. In addition, the G500 Group presented a higher presence of urate/uric acid crystals after urinary acidification, which are closely related to urinary pH.

Apesar de cristais urinários serem componentes habituais, a formação de urolitíase é sempre precedida dessas concreções. O presente estudo objetivou identificar a mudança do perfil cristalúrico em ovinos suplementados com cloreto de amônio. Foram utilizados 25 ovinos, machos, com idade de três meses, confinados e distribuídos aleatoriamente em três grupos: grupo controle (GC) (n=5) não recebeu cloreto de amônio; grupo G200 (n=10) (200mg/kg) recebeu cloreto de amônio por 56 dias consecutivos; grupo G500 (n=10) (500mg/kg) recebeu cloreto de amônio por 56 dias consecutivos, administrados diariamente por via oral. Os momentos (M) de colheita de amostras e avaliação clínica foram realizados com intervalo de sete dias, sendo M0 (imediatamente antes da administração do cloreto de amônio), M1 (sete dias após) até M8, totalizando 70 dias de confinamento. As amostras de urina foram analisadas para se identificar a presença, o tipo e a quantidade de cristais. Houve aumento da cristalúria em todos os grupos em relação ao tempo por influência dietética, principalmente no GC, que apresentou mais cristais de fosfato de cálcio amorfo e oxalato de cálcio. Além disso, o grupo G500 apresentou maior presença de cristais de urato/ácido úrico após acidificação urinária, estando esses intimamente relacionados ao pH urinário.

Cystitis in a bitch with chronic kidney disease caused by multidrug-resistant Escherichia coli

Background: In dogs with bacterial cystitis that is resistant to multiple antibiotics, resulting from repeated infections andantimicrobial administration, especially if the dog has impaired renal function and the induction of systemic side effectsby intravenous or oral administration is a concern, intravesical instillation of antibiotics might represent an alternativetreatment option. In human and veterinary medicine, a number of studies showed intravesical instillation of antibiotics iseffective for the therapy multidrug-resistant bacterial urinary tract infection (UTI). This report firstly illustrates successfulintravesical meropenem treatment of a UTI caused by multidrug-resistant Escherichia coli with no systemic side effectsin dog with chronic kidney disease (CKD).Case: A 15-year-old spayed female Maltese was presented with recurrent bacterial cystitis. The risk factors for the recurrent UTI were spinal cord injury and CKD which had been managed for 1 year. Ultrasound-guided cystocentesis wasperformed to obtain a urine sample for urinalysis, bacteriologic culture, and antibiotic susceptibility testing. Bacterialcystitis caused by multidrug-resistant Escherichia coli was diagnosed on the basis of bacterial culture, and antimicrobialsusceptibility testing. Because the dog had CKD, reducing the clearance of meropenem, intravesical instillation of antibiotics was initiated. The intravesical instillation process consisted of the emptying of the urinary bladder, infusion of adiluted meropenem solution (8.5 mg/kg diluted in 20 mL of saline solution) into the bladder through a urethral catheter,and retention of the meropenem solution in the bladder for 1 h, and its removal. The procedure was repeated every 8 h. Onday 8 of the intravesical instillation therapy, bactereologic culture yielded a growth of E. coli (50,000 CFUs/mL), whichwas less than previously obtained. the concentration of the meropenem solution...

Physicochemical techniques for determining the composition of canine and feline uroliths: a literature review / Técnicas físico-químicas para determinação da composição de urólitos em caninos e felinos: uma revisão de literatura

Urinary lithiasis has been reported as a problem that affects humankind since ancient times and has been described in several animal species. The condition is a consequence of other diseases that may be present in the urinary system or related to other body disorders. The stone composition needs to be analyzed to identify the possible causes that led to the formation and development of uroliths. For this, several techniques are currently available, some of which are promptly accessible, while others are not. Thus, this literature review aimed to perform a brief introduction on urolithiasis, present the most used techniques in the analysis of the composition of canine and feline uroliths and point out the advantages and disadvantages of each technique.

A litíase urinária foi reportada como um problema que atinge a humanidade desde a antiguidade e já foi descrita em diversas espécies de animais. A doença é considerada consequência de outras enfermidades que podem estar presentes no sistema urinário, ou relacionados com outros distúrbios do organismo. Para identificar as possíveis causas que levaram à formação e desenvolvimento de urólitos é importante analisar a composição dos cálculos. Para isso, existem várias técnicas disponíveis atualmente, algumas de mais fácil acesso e outras, nem tanto. Dessa forma, objetiva-se com a presente revisão realizar uma breve introdução sobre a urolitíase e apresentar as técnicas mais utilizadas na análise da composição de urólitos, em caninos e felinos, bem como apontar as vantagens e desvantagens de cada uma das técnicas.

Hematúria macroscópica em equinos associada à infecção por Leptospira interrogans / Macroscopic haematuria in horses associated with Leptospira interrogans infection

Hematúria é uma grave manifestação clínica de doença do sistema urinário, ocorrendo sob as formas micro ou macroscópica. Neste artigo relatam-se dois casos de hematúria macroscópica associada à infecção por Leptospira interrogans sorogrupo Canicola. O exame clínico inicial revelou hematúria macroscópica, taquicardia, taquipneia, febre, elevação do tempo de perfusão capilar, hipomotilidade intestinal, além de icterícia da mucosa oral. Leucocitose, proteinúria, glicosúria, piúria e azotemia foram achados comuns aos dois casos. Teste de Soroaglutinação Microscópica foi realizado para titulação de anticorpos contra Leptospira interrogans. Tratamento incluiu medidas terapêuticas de suporte (fluidoterapia), controle da hematúria e antibioticoterapia. Sete dias após manifestação dos sinais clínicos iniciais, ambos animais receberam alta hospitalar após remissão dos sinais clínicos.

Haematuria is a serious clinical manifestation of urinary system disease, occurring in micro or macroscopic forms. In this article two cases of macroscopic haematuria associated with Leptospira interrogans serogroup Canicolainfection are related. The initial clinical examination revealed macroscopic haematuria, tachycardia, tachypnea, fever, increased capillary perfusion time, intestinal hypomotility, in addition to jaundice of the oral mucosa. Leukocytosis, proteinuria, glycosuria, pyuria and azotemia were common findings in both cases. Microscopic serum agglutination test was performed for titration of antibodies against Leptospira interrogans. Treatment included supportive therapeutic measures (fluid therapy), hematuria control and antibiotic therapy. Seven days after the manifestation of the initial clinical signs, both animals were discharged from the hospital without complications.

Association between Neospora caninum seropositivity and reproductive disorders in girolando cows / [Associação entre a soropositividade para Neospora caninum e distúrbios reprodutivos em vacas girolando]

The aim of this study was to investigate the presence of anti-Neospora caninum antibodies in Girolando cows, in order to evaluate the association between seropositivity and reproductive disorders. Blood samples were collected from 40 dairy cows in their reproductive phase from the cranial superficial epigastric vein. The blood samples were tested using the Indirect Fluorescence Antibody Test (IFAT) to detect anti-N.caninum antibodies. The serological results were used to verify whether there was any association with the manifestation of reproductive disorders based on data from the records of reproductive history from 2017 to 2018 as well as the clinical observations of the herd throughout this study. The Fisher exact test was used to verify the existence of an association between the serology and reproductive disorders, adopting a 95% confidence level. The serological results showed a 27.5% seroprevalence in the herd for N. caninum, however, after statistical analysis, no association between seropositivity and reproductive disorders was found in the evaluated herd. Although the studied population is infected with Neospora caninum, we can infer that anti-Neospora caninum antibodies present in Girolando dairy cows at the UFRRJ Dairy Cattle Facility are not associated with the occurrence of reproductive disorders.(AU)

O objetivo deste estudo foi investigar a presença de anticorpos anti-Neospora caninum em vacas Girolando, avaliando-se a associação entre a soropositividade e os distúrbios reprodutivos. Foram coletadas amostras de sangue da veia epigástrica superficial cranial de 40 vacas leiteiras em fase reprodutiva, sendo as amostras testadas pela reação de imunofluorescência indireta (RIFI) para detecção de anticorpos anti-N. caninum. A partir dos resultados sorológicos, foi realizada a verificação de associação, ou não, com a manifestação de distúrbios reprodutivos, coletados nos registros de histórico reprodutivo entre 2017 e 2018 e observações do rebanho no transcorrer do estudo. O teste exato de Fisher foi utilizado para verificar a existência de associação entre a sorologia e os distúrbios reprodutivos, adotando-se nível de confiança de 95%. O resultado do estudo demonstrou uma soroprevalência no rebanho de 27,5% para N. caninum, contudo, após análise estatística, não foi confirmada a associação entre soropositividade e distúrbios reprodutivos no rebanho avaliado. Apesar de a população estudada estar infectada com o Neospora caninum, pode-se inferir que anticorpos anti-Neospora caninum presentes em vacas leiteiras Girolando do Setor de Bovinocultura de Leite da UFRRJ não estão associados à ocorrência de distúrbios reprodutivos.(AU)

Aspectos clínicos e hematológicos da doença do trato urinário inferior em felinos / Clinical and haematological aspects of feline lower urinary tract disease

A obstrução uretral é uma condição urológica considerada comum e potencialmente fatal na doença do trato urinário inferior (DTUIF). Os principais sinais clínicos da obstrução uretral são: polaquiúria, disúria, hematúria, periúria, insucesso na micção, angústia, anorexia, hipotermia, ausência de libido ou ereção e durante o exame clínico observa-se a vesícula urinária repleta e firme, condições que conduzem à necessidade de intervenção imediata. Diante disso, o objetivo do trabalho foi descrever e comparar alterações clínicas e hematológicas de gatos com doença do trato urinário inferior obstrutiva e gatos saudáveis. No estudo, foram admitidos 30 gatos e distribuídos em dois grupos: o grupo controle composto por animais sem afecções clínicas notáveis e o grupo obstruído com animais diagnosticados clinicamente com quadro de obstrução urinária. Foi realizada anamnese detalhada dos animais, histórico, realização de exame físico geral com ênfase no trato urinário, ultrassonografia e exame hematológico completo. As principais alterações clínicas dos animais obstruídos foram desidratação, mucosas hipocoradas e hipotermia. O hemograma dos animais obstruídos revelou diferença significativa (p<0,05) para as médias encontradas quando comparados com o grupo controle para contagem de eritrócitos, concentração de hemoglobina e volume globular, tendo o grupo obstruído apresentado valores inferiores ao controle. Pode-se concluir que os exames hematológicos podem identificar alterações importantes do quadro inflamatório geral em animais obstruídos, apresentando neutrofilia, linfopenia e monocitose. Além disso, observou-se que o monitoramento longitudinal possibilita acompanhar a progressão da enfermidade e o risco de anemia bem como a melhora do quadro clínico.

Urethral obstruction is a urological condition considered to be common and potentially fatal in lower urinary tract disease (DTUIF). The main clinical signs of urethral obstruction are: pollakiuria, dysuria, hematuria, periuria, urination failure, anguish, anorexia, hypothermia, absence of libido or erection and during the clinical examination a full and firm urinary vesicle is observed, conditions that lead to the need for immediate intervention. Therefore, the objective of the study was to describe and compare clinical and hematological changes in cats with obstructive lower urinary tract disease and healthy cats. In the study, 30 cats were admitted and distributed in two groups: the control group composed of animals without clinical diseases and the obstructed group with animals clinically diagnosed with urinary obstruction. Detailed anamnesis of the animals, history, general physical examination with emphasis on urinary examination, ultrasound and complete hematological examination were performed. The main clinical changes in the obstructed animals were dehydration, bleached mucous membranes and hypothermia. The blood count of the obstructed animals showed a significant difference (p <0.05) to the average found when compared to the control group for erythrocyte count, hemoglobin concentration and globular volume, and the obstructed group presented values lower than the control. It can be concluded that hematological tests can identify important changes in the general inflammatory condition in obstructed animals, presenting neutrophilia, lymphopenia and monocytosis. In addition, longitudinal monitoring allows the progress of the disease and the risk of anemia to be monitored, as well as improvements in the clinical condition.

Antibacterial activity of 3, 3', 4'-Trihydroxyflavone from Justicia wynaadensis against diabetic wound and urinary tract infection

The present investigation was designed to study the effect of an active compound isolated from Justicia wynaadensis against multi drug resistant organisms (MDRO's) associated with diabetic patients. The drug resistant pathogens implicated in wound and urinary tract infection of diabetic patients were isolated and identified by molecular sequencing. Solvent-solvent fractionation of crude methanol extract produced hexane, chloroform, ethyl acetate and methanol-water fraction, among which chloroform fraction was found to be potent when compared with other three fractions. Further, chloroform fraction was subjected to preparatory HPLC (High-Performance Liquid Chromatography), that produced four sub-fractions; chloroform HPLC fraction 1 (CHF1) through CHF4. Among the sub-fractions, CHF1 inhibited the pathogens effectively in comparison to other three sub-fractions. The purity of CHF1 was found to be >95%. Therefore, CHF1 was further characterized by NMR and FTIR analysis and based on the structure elucidated, the compound was found to be 3,3',4'-Trihydroxyflavone. The effective dose of this bioactive compound ranged from 32 µg/mL to 1.2 mg/mL. Thus, the present study shows that 3,3',4'-Trihydroxyflavone isolated from J. wynaadensis is an interesting biopharmaceutical agent and could be considered as a source of antimicrobial agent for the treatment of various infections and used as a template molecule for future drug development.(AU)

Feline Pandoras Syndrome: A Bibliographic Review / Síndrome De Pandora Em Felinos: Revisão De Literatura / Síndrome De Pandora En Felinos: Revisión De Literatura

Pandora"s syndrome is a multifactorial disorder in which other systemic aetiologies may influence clinical signs in a target organ. In cats with chronic and idiopathic lower urinary tract disease, diagnosis requires a criteria of exclusion and must fulfil at least four other criteria as a confirmation of the diagnostic. Fundamental treatment of the syndrome is based on the elimination of stress factors as well as environmental enrichment.(AU)

A síndrome de Pandora é uma doença de caráter multifatorial onde outras etiologias sistêmicas podem influenciar sinais clínicos em um órgão alvo. Em gatos com doença do trato urinário inferior crônicas e idiopáticas, o diagnóstico além de ser por exclusão, deve preencher no mínimo três outros critérios para que a síndrome seja ocorrente.

Pandora"s syndrome is a multifactorial disorder in which other systemic aetiologies may influence clinical signs in a target organ. In cats with chronic and idiopathic lower urinary tract disease, diagnosis requires a criteria of exclusion and must fulfil at least four other criteria as a confirmation of the diagnostic. Fundamental treatment of the syndrome is based on the elimination of stress factors as well as environmental enrichment.

A síndrome de Pandora é uma doença de caráter multifatorial onde outras etiologias sistêmicas podem influenciar sinais clínicos em um órgão alvo. Em gatos com doença do trato urinário inferior crônicas e idiopáticas, o diagnóstico além de ser por exclusão, deve preencher no mínimo três outros critérios para que a síndrome seja ocorrente. Seu tratamento fundamental baseia-se na eliminação de fatores estressantes bem como o enriquecimento ambiental.

Urolithiasis with uroperitoneum and hydronephrosis in grazing cattlein Southern Brazil / Urolitíase com uroperitônio e hidronefrose em bovinos a campo no Sul do Rio Grande do Sul

The purpose of this paper was to describe obstructive urolithiasis with uroperitoneum and hydronephrosis in range cattle in southern Rio Grande do Sul. The disease was observed in castrated male cattle, aged between 18 months and 3 years in a herd of 200 steers that were in a ryegrass pasture during the winter and a native pasture during the summer. Different mineral salts were used as a supplement for the animals during the two seasons of the year. Cattle presented a progressive abdominal distention, depression and dehydration ranging from 10 days to one month in duration. One animal was necropsied, and approximately 50 liters of urine (uroperitoneum) in the abdominal cavity were observed. The bladder had a small rupture and was adhered to the pelvic cavity. The right kidney was enlarged with hydronephrosis. Uroliths of more than 1cm in diameter were housed in the penile urethra. In this study, the disease occurred probably because of mineral salt supplementation, resulting in an imbalance of calcium and phosphorus intake.

O objetivo deste trabalho foi descrever urolitíase obstrutiva associada a hidroperitônio e hidronefrose em bovinos no sul do Rio Grande do Sul. A doença foi observada em um rebanho de 200 bovinos machos castrados, com idade entre 18 meses e três anos, mantidos a campo, que permaneciam no inverno em pastagem de azevém e no verão em campo nativo e eram suplementados com diferentes sais minerais nas duas épocas do ano. Os bovinos afetados apresentavam aumento de volume abdominal progressivo, depressão e desidratação, com evolução de 10 dias a um mês. Um bovino foi necropsiado e havia na cavidade abdominal aproximadamente 50 litros de urina (uroperitônio). A bexiga apresentava pequena ruptura e aderência à cavidade pélvica. O rim direito estava aumentado de tamanho e apresentava hidronefrose. Havia urólitos de mais ou menos 1cm de diâmetro alojados na uretra peniana. Neste caso é provável que a doença tenha ocorrido em consequência da suplementação com sal mineral contendo quantidades inadequadas de cálcio e fósforo levando a um desequilíbrio entre estes minerais.

Uretrolitíase obstrutiva em equino / Obstructive urethrolithiasis in a horse

Background: The presence of macroscopic concretions in the urinary system is called urolithiasis. In horses the occurrence is rare. The calculi are generally large and unique spicule concretions, composed of calcium carbonate crystals. Less commonly, the concretions are of mixed crystals of calcium carbonate and of calcium phosphate. The aim of the this work was to report a case of obstructive urethrolithiasis in a horse.Case: A 1-year-and-5-month-old, undefined breed, uncastrated male presented tenesmus, strangury, and dysuria. The horse died seven days after the onset of clinical signs and was referred for necropsy. At necropsy, samples were collected from organs of the abdominal cavity, thoracic cavity, central nervous system and integumentary system. The fragments were fixed in 10% formaldehyde, cleaved, routinely processed for histology and stained with hematoxylin and eosin. A urinary calculus collected during necropsy was sent for chemical analysis. In the abdominal cavity, a large quantity of citrus liquid of uremic odor was observed. Deposition of fibrin filaments in the peritoneum was observed, as well as in diaphragm and abdominal organs. Serosa of the small and large intestine was red with evidence of the capillaries. Kidneys presented multiple slightly protrusive white areas with a maximum diameter of 3 mm. When cutting, these areas were limited to the cortical region. There was rupture of the urinary bladder, diffuse loss of the mucosa with capillary exposure and evidence, as well as the deposition of fibrin and crude blood clots. The opening of the penile urethra presented a urolith of approximately 3.5 x 3 cm in size, with a rough and porous surface, light brown and of a stony consistency. Necrosis of the mucosa and hemorrhage were also observed in the urethra....
