Acquired partial lower urinary tract obstruction caused by intravesical ureterocele in an adult dog.

Ureterocele is an uncommon condition in dogs characterised by a cystic dilation of the submucosal portion of the distal ureter. A 4-year-old intact male Siberian husky with a 4-month previous diagnosis of ureterocele was presented for pollakiuria. Abdominal ultrasound showed increased dimensions of the ureterocele, and a retrograde positive contrast urethrocystography detected a filling defect of the bladder neck lumen. The position of ureterocele was considered responsible for the partial urinary obstruction. This hypothesis is supported by the resolution of pollakiuria after surgical ureterocele resection. Based on a literature search, this is the first case of an intravesical ureterocele causing partial urinary obstruction in dogs. Ureterocele should be considered as a differential diagnosis in patients with pollakiuria.

Prevalence and Characterization of Urinary Tract Infection in Owned Dogs and Cats From Spain.

Bacterial urinary tract infection (UTI) is a common clinical concern in dogs. However, incidence of feline UTI is much lower than in dogs although an increasing prevalence has been registered. The main objective of the present study was to describe and characterize the prevalence of urinary tract pathogens in urine samples of dogs and cats with urinary clinical signs throughout different Spanish provinces. Secondary aims were to determine if there were differences in urine sample characterizations based on species (i.e., dog and cat) or season. Dogs were found to have a higher rate of positive urinary cultures than cats (39.3% and 24.7% of the cultures submitted, respectively). The bacterial genera most commonly isolated in dogs were Escherichia spp. (45.3%), Proteus spp. (13.2%), Staphylococcus spp. (11%), and Enterococcus spp. (8.6%). Whereas in the feline population, Escherichia spp. (42.7%), Enterococcus spp. (22.2%), and Staphyloccoccus spp. (15.2%) were the most frequently isolated bacteria. The highest rates of positive urine cultures were registered in Melilla (70%), Zamora (66.7%), Teruel (64.3%), and Guadalajara (60%). Moreover, the proportion of positive urine cultures was not homogeneously distributed across provinces. Finally, some seasonality was found among most isolated bacterias. Enterococcus spp. was significantly more prevalent in summer, whereas Escherichia spp. and Proteus spp. were more commonly isolated in spring and Pseudomonas spp. in autumn.

Prevalence of Proteinuria in Owned Dogs from Italy: A Multicentric Study.

Even though proteinuria is related to different causes, when it is persistent and associated with inactive urinary sediment, it is primarily due to kidney disease. Early detection of proteinuria allows us to identify several pathological conditions. The aim of the study was screening a canine population not known as being proteinuric, by the urinary dipstick. The study was carried out in seven Italian veterinary clinics during a period of six weeks. Dogs were enrolled with no restriction of sex or age. Females in estrus, dogs with signs of genitourinary diseases, or those previously diagnosed with proteinuric nephropathy were excluded. Dogs were considered "nonproteinuric" (NP) in case of negative dipstick test or "suspected proteinuric" (SP), if positive at the dipstick. When possible, proteinuria was confirmed by UPC ratio. A total of 1156 dogs were evaluated: 414 were from northern Italy and 742 from southern Italy. Based on dipstick test, 655 (56.6%) dogs were NP, while 501 (43.3%) were SP. Among the NP dogs 225 out of 414 (54.3%) were in northern Italy and 430 of 742 (57.9%) in southern Italy. One hundred eighty-nine of 414 (45.7%) SP dogs were identified in northern Italy and 312 of 742 (42.1%) in southern Italy. No statistical difference was found between the North and the South of Italy. UPC was available in 412 out of 501 SP samples: proteinuria was confirmed in 263 (63.86%) samples. Results from our study showed a high percentage of suspected proteinuric dogs, apparently not affected by renal diseases, together with the absence of statistically significant differences based on geographical area.

The effect of renal diet in association with enalapril or benazepril on proteinuria in dogs with proteinuric chronic kidney disease.

Treating proteinuria in dogs reduces the progression of chronic kidney disease (CKD); renal diets and angiotensin-converting enzyme (ACE)-inhibitors are cornerstones of treatment. Whether different ACE-inhibitors have distinct kidney protective effects is unknown; it is therefore hypothesized that renal diets and enalapril or benazepril have different beneficial effects in proteinuric CKD dogs. Forty-four dogs with proteinuric CKD (IRIS stages 1-4) were enrolled in the study and were fed renal diet for 30 days. Thereafter, they were randomly assigned to one of 2 groups. Dogs in group A (n=22) received enalapril (0.5 mg/kg, q12h) and in group B (n=22) benazepril (0.5 mg/kg, q24h); in both groups, dogs were fed the same renal diet. After randomization, dogs were monitored for 120 days. Body weight and body condition score (BCS), serum concentrations of creatinine, blood urea nitrogen (BUN), albumin and total proteins, and urine protein-to-creatinine (UPC) ratio were compared at different time-points. After 30 days of renal diet, creatinine, BUN and UPC ratio decreased significantly (p<0.0001). Compared to randomization, body weight, BCS, albumin, total proteins, creatinine and BUN did not vary during follow-up in the 44 dogs and differences between group A and B were not observed. However, the UPC ratio of group A at day 60, 90 and 150 was significantly lower than in group B and compared to randomization (p<0.05). In group B it did not vary overtime. It is concluded that the renal diet is beneficial to decrease creatinine, BUN and UPC ratio in proteinuric CKD dogs. Enalapril further ameliorates proteinuria if administered along with renal diet.

Outcomes from ischemic stroke subtypes classified by the Oxfordshire Community Stroke Project: a systematic review.

BACKGROUND: Stroke is a highly heterogeneous disorder with distinct subtypes, each presenting specific clinical aspects. Information on prognosis of ischemic stroke subtypes help to improve clinical management and rehabilitation treatments. AIM: Summarize findings of studies on outcome in stroke subtypes categorized by use of the Oxfordshire Community Stroke Project (OCSP) classification. DESIGN: Systematic review. SETTING: Not applicable. POPULATION: Adult post-stroke patients. METHODS: Systematic literature research of five databases was undertaken to identify relevant studies. Outcomes were examined in terms of impairment, activity restriction and participation restriction. Quality of Life and mortality was also examined for each study. RESULTS: Sixteen studies met inclusion criteria. Most studies measure outcome in terms of activity limitations and participation restriction. Only one study measures impairment. TACI group have poor outcomes in comparison with other groups. Outcomes of LACI, PACI and POCI groups are controversial. CONCLUSION: Stroke subtype is a factor influencing outcome. However, differences among groups, overall in terms of impairment, should be further investigated. CLINICAL REHABILITATION IMPACT: Different prognosis of stroke subtypes may imply different rehabilitation managements.

Ultrasonographic evaluation of the size of the adrenal glands of 24 diseased cats without endocrinopathies.

The ultrasonographic measurements of the adrenal glands of 24 diseased cats without a clinically or laboratory identifiable endocrinopathy were evaluated retrospectively. The mean (sd) thickness of the left adrenal glands was 3.8 (0.8) mm and their mean length was 11.3 (2.8) mm; the thickness of the right glands was 4.5 (1.0) mm and their length was 9.8 (2.4) mm. The products of thickness and length were 43.9 (20.2) mm(2) for the left gland and 45.7 (19.7) mm(2) for the right gland. There were no significant correlations between the bodyweight, body surface area or body condition scores of the cats and the thickness, length or the product of thickness and length of either gland.

Selective detection of human papilloma virus DNAs by specific synthetic DNA probes.

Specific oligodeoxynucleotide probes ranging from 20 to 35 nucleotides were defined to differentiate each of the HPV1a, 5, 6b, 8, 11, 16, 18 and 33. They were chosen using computer programs developed to compare simultaneously several 8000 bp long DNA sequences. Sequences common to all and to specific groups of the HPV DNA were also selected. Specificity of 32P-labelled probes for HPV6b, 11, 16, 18 and 33 was demonstrated and the sensitivity of the assays was evaluated by filter hybridization with viral clones and with DNA from cervical tumor biopsies.
