Carcinoma de células transicionales en perros: Un informe de dos casos, madre e hija

The transitional cell carcinoma is usually located in the trigone region of the bladder, and shows nonspecific clinical signs of the lower urinary tract such as hematuria, strangury, pollakiuria and urinary incontinence. The urethral and ureteral obstructions occur in some cases. Etiological factors such as endogenous and iatrogenic have been listed as the cause of disease. The objective of this report is to describe the process and treatment of two cases of transitional cell carcinoma presented simultaneously in two dogs, mother and daughter, that showed hematuria and post-renal azotemia, both with tumor in the trigone of bladder. After partial cystectomy ureteroneocistostomia, the diagnosis of transitional cell carcinoma was confirmed by histopathological analysis of bladder tissue. Patients received firocoxib as adjuvant to surgery. It is concluded that the surgical procedure associated with the use of specific anti-inflammatory COX-2 provided a better quality of life in both patients.

Ocorrência de cristais em plantas medicinais utilizadas no tratamento da nefrolitíase: Paradoxo?

Nephrolithiasis (kidney stones) can be seen as a common clinical condition responsible for substantial economic, social and psychological costs, due to its high morbidity, especially since it affects adults in their productive phase. Its development in the urinary tract is a complex and multifactorial process. The majority of kidney stones are made of calcium oxalate. A lot of plants are used to treat nephrolithiasis and they often exhibit calcium oxalate crystals in the parts that are employed for this medicinal purpose, representing a possible risk. In this light, we performed a literature review via the databases Scielo, PubMed and Medline and found 28 articles reporting the traditional use of plants in the treatment of nephrolithiasis. The occurrence of calcium oxalate crystals was indicated in 19 species. We argue that the use of these plants could give rise to adverse effects in people who are prone to form calcium oxalate stones in the kidney.

The renin-angiotensin system plays a major role in voiding dysfunction of ovariectomized rats

Aims: The renin-angiotensin system (RAS) plays a major role in cardiovascular diseases in postmenopausal women, but little is known about its importance to lower urinary tract symptoms. In this study we have used the model of ovariectomized (OVX) estrogen-deficient rats to investigate the role of RAS in functional and molecular alterations in the urethra and bladder. Main methods: Responses to contractile and relaxant agents in isolated urethra and bladder, as well as cystometry were evaluated in 4-month OVX Sprague-Dawley rats. Angiotensin-converting enzyme activity and Western blotting for AT1/AT2 receptors were examined. Key findings: Cystometric evaluations in OVX rats showed increases in basal pressure, capacity and micturition frequency, as well as decreased voiding pressure. Angiotensin II and phenylephrine produced greater urethral contractions in OVX compared with Sham group. Carbachol-induced bladder contractions were significantly reduced in OVX group. Relaxations of urethra and bladder to sodium nitroprusside and BAY 41-2272 were unaffected by OVX. Angiotensin-converting enzyme activity was 2.6-fold greater (p < 0.05) in urethral tissue of OVX group, whereas enzyme activity in plasma and bladder remained unchanged. Expressions of AT1 and AT2 receptors in the urethra were markedly higher in OVX group. In bladder, AT1 receptors were not detected, whereas AT2 receptor expression was unchanged between groups. 17β-Estradiol replacement (0.1 mg/kg, weekly) or losartan (30 mg/kg/day) largely attenuated most of the alterations seen in OVX group. Significance: Prolonged estrogen deprivation leads to voiding dysfunction and urethral hypercontractility that are associated with increased ACE activity and up-regulation of angiotensin AT1/AT2 receptor in the urethral tissue. © 2013 Elsevier Inc.
