The Role of Viruses in Feline Lower Urinary Tract Disease

Viruses have been implicated as causative agents in the etiopathogenesis of some forms of feline lower urinary tract disease (LUTD). This hypothesis was supported by isolation of feline calicivirus, bovine herpesvirus 4 (strain FeCAHV), and feline syncytia-forming virus from cats with naturally occurring LUTD, and by experimental studies of induced viral urinary tract infection. Results of early clinical studies yielded contradictory results concerning the role of viruses in feline LUTD. However, recent detection of bovine herpesvirus 4 antibodies in feline serum samples and discovery of calicivirus-like particles in crystalline/matrix urethral plugs obtained from cats with naturally occurring LUTD, suggests the need to reexamine the etiopathologic role of viruses using contemporary methods of virus identification and localization.

Evaluation of the Rabbit Urinary Tract

Urinary tract disease is not an uncommon presentation for pet rabbits. It is beneficial for the veterinarian treating these patients to have a thorough understanding of a rabbit's urogenital anatomy, renal physiology, and diseases that affect the kidney and urinary tract. The evaluation of the rabbit urinary tract requires a multidisciplinary approach including the procurement of a thorough history, signalment, assessment of clinical signs, physical examination, and diagnostic test results. To obtain a definitive disease diagnosis, more intensive diagnostic testing may be required, including contrast radiography, ultrasound evaluation, and histopathological assessment of biopsy samples. This article will provide information to aid in the diagnosis and treatment of rabbit urinary tract diseases.     

Relationship of Lower Urinary Tract Signs to Seropositivity for Feline Immunodeficiency Virus in Cats

A group of 41 cats with signs of lower urinary tract disease was compared to a group of 41 cats without any history of disease for prevalence of seropositivity for feline immunodeficiency virus (FIV). The group of healthy cats was similar in age and gender to the group of cats with signs of lower urinary tract disease. Three of the cats with lower urinary tract disease and one control cat were seropositive for FIV.
This difference was not statistically significant. The most common cause of lower urinary tract signs was idiopathic. Only 7 cats had urinary tract infection, most associated with perineal urethrostomy or catheterization. Six of the cats with bacterial urinary tract infections were FIV negative.

人体血管三维重建图像在影像解剖学中的应用

目的:构建基于CT图像后处理技术的人体血管三维图像数据库,用于观察其在影像解剖学学习中应用效果。方法:对照组为我学院2016级影像技术专业学生,使用解剖图谱等传统学习方法。研究组在学习中使用基于CT后处理技术的正常人体血管系统图库。两组学习结束后同时进行考试并填写调查问卷,进行统计学分析。结果:对比两组同学的成绩平均值,研究组学生的测试平均值为(82. 59±4. 28)分,明显高于对照组(71. 45±3. 78)分,差异具有统计学意义(P <0. 05);对降低学习难度、易于理解和记忆、提高学习兴趣、学习效率的提高、血管三维数据库的满意度进行调查,结果显示,研究组学习效果评分结果均优于对照组,各项评分结果比较差异均有统计学意义(P <0. 05)。结论:在影像解剖学学习中使用基于CT后处理工作站构建的人体血管系统三维图像数据库可有效提升影像解剖学中血管系统的学习效果。     

Effect of Therapy on Susceptibility to Urinary Tract Infection in Male Cats with Indwelling Urethral Catheters

Indwelling urinary catheters with a closed urine collection system were maintained in 30 male cats for 3 days after induction of irritant cystitis. All cats received subcutaneous fluids during the 3 days the catheters were in place. The effects of four different treatment regimens on urinary tract infection rates, incidence of urethral obstruction, and development of urinary tract lesions over a 10-day period were compared with results in a nontreated group. Treatments were 1) amoxicillin for 5 days PO; 2) prednisolone for 5 days PO; 3) both amoxicillin and prednisolone for 5 days PO; and 4) dimethylsulfoxide (DMSO) for 3 days intravesicularly. Euthanasia was done before the end of the 10-day experimental period if the cats had two bouts of urethral obstruction or if the cats became uremic for causes unrelated to urethral obstruction. Seven cats were euthanatized before the conclusion of the experiment. These cats had been treated with prednisolone, prednisolone and amoxicillin, or DMSO. All cats that received amoxicillin alone or no therapy survived the 10-day period. Mortality was due to repeated urethral obstruction or to uremia associated with pyelonephritis or papillitis. Urinary tract infection rate was similar in all groups. The group treated with prednisolone alone had the highest incidence of renal infection. Inflammatory lesions in the lower urinary tract were similar in all groups. In conclusion, persistent urinary tract infection often develops in cats with cystitis after indwelling urethral catheterization even when closed systems of urine drainage are used.(ABSTRACT TRUNCATED AT 250 WORDS)
