The objective of this work was to identify and determine the magnitude of proteinuria and its electrophoretic pattern characterization in dogs with chronic diseases pathophysi- ologically related to proteinuria. With the studied patients, five groups were formed. The control group (CG) contained non-proteinuric cases. The cases with proteinuria were classified into four groups according to the concurrent disease: chronic inflammatory diseases (IG), neoplasms (NG), heart diseases (HG), and endocrine diseases (EG). For the statistical analysis, descriptive statistics and non-parametric tests were used. Data from 264 dogs were obtained; in the disease groups, proteinuria was observed in more than 30% as the only finding of kidney disease, evidencing a greater risk factor for proteinuria in the HG group (OR 4.047, CI 1.894–8.644, p < 0.0001). In the HG, NG, and EG groups, a higher frequency of glomerular pattern (GEP) related to glomerular hypertension was observed; in the IG, a higher frequency of mixed pattern (MEP) was observed. These findings are secondary to the hyperfiltration process that affects the glomerulus and the renal tubule. 2023-04-19T00:00:00Z http://hdl.handle.net/20.500.11799/143905 A Retrospective Study of Laparoscopic Cryptorchidectomy in 19 Cats with Intra-Abdominal Testes Villalobos Gomez, JJ; Del Ángel Caraza, J; Tapia Araya, A; Brandao, F; Hernández López, CA; Martínez Gomariz, FM; Botero Crespo, CE; Properzi, R Cryptorchidism is the failure of one or both testes to descend into the scrotum and remain there by 7–8 months of age and is considered the most common congenital disease in male dogs and cats. The prevalence of cryptorchidism in cats is 1.3–6.2%, and can be categorized as unilateral or bilateral and, depending on the location of the testes, as intra-abdominal, inguinal, or pre-scrotal. Due to the risk of testicular torsion, the development of testicular neoplasia and the fact that the cryptorchid testes still produce testosterone, cryptorchidectomy is the treatment of choice for these affected cats. For the intra-abdominal testes, a laparotomy for a caudal midline approach is generally recommended. However, laparoscopy in cryptorchidectomy in cats has been documented in a few clinical cases reports. The aim of the study was to report the short-term clinical outcomes for 19 cryptorchid cats with intra-abdominal testes that underwent cryptorchidectomy with laparoscopic techniques. The results of this study suggest that laparoscopic cryptorchidectomy is an appropriate procedure to treat cryptorchid cats, with all benefits of the minimal invasive surgery, such as a better visibility of abdominal structures, shorter hospitalization times, lower morbidity, less surgical site infections, and most importantly, minimized surgical pain and discomfort. 2023-01-03T00:00:00Z http://hdl.handle.net/20.500.11799/143904 Canine Silica Urolithiasis in Mexico, Associated with the Concentration of Dissolved Silica in Tap Water MENDOZA LOPEZ, CLAUDIA IVETH; Javier Del Ángel-Caraza, /; Aké-Chiñas, María Alejandra; QUIJANO HERNANDEZ, ISRAEL; Esteller Alberich, M. V. Silica urolithiasis is infrequent in dogs, but in Mexico represents 12.9%. Our hypothesis is the consumption of high amounts of silicates in the diet, especially that dissolved in tap water. The objective of this study was to determine the concentrations of silica in the tap water in different geographical areas and their relationship with cases of silicate urolithiasis in dogs. From 179 cases of silicate urolithiasis, 98.9% were from dogs within a geographic area called the Trans-Mexican Volcanic Belt, which represents a cross shaft to the center of the country. Silica concentrations in tap water ranged between 3 and 76 mg/L, with a range of 27 to 76 mg/L, a mean of 49.9 ± 12 mg/L within the Trans-Mexican Volcanic Belt, and a concentration from 3 to 30 mg/L, with a mean of 16.4 ± 7 mg/L outside this area; these were significantly different (p < 0.001). These findings demonstrate that there is a geographic risk factor for silicate urolithiasis in urolith-forming dogs, related to the consumption of tap water with a high concentration of silica. Further studies are necessary to identify this same pathophysiological association in other species. 2021-07-05T00:00:00Z http://hdl.handle.net/20.500.11799/143903 Canine Silica Urolithiasis in Mexico (2005–2018) Mendoza-López, Claudia Ivete; Del Ángel Caraza, J; AKE CHIÑAS, MARIA ALEJANDRA; QUIJANO HERNANDEZ, ISRAEL; Marco Antonio Barbosa Mireles, / A higher frequency of canine silica urolithiasis is found in Mexico, unlike <1–8% in other countries. The causes and risk factors for this pathology are unknown. However, we consider the consumption of high amounts of silica from the solid diet or dissolved in water as the only hypothesis. This study aimed to identify the risk factors for silica urolithiasis in dogs from Mexico. A total of 1383 clinical cases of canine urolithiasis were included in this study; the uroliths were analyzed to determine their mineral composition by stereoscopic microscopy and infrared spectroscopy. Of these cases, 12.94% were considered pure silica uroliths; however, considering the mixed and compound uroliths, the frequency increased to 17.42%. Male dogs aged >6 years and large breeds, especially Labradors and Golden retrievers, were at significant risk for this disease. 98.88 % of the clinical cases studied were found in the central axis of the country, considering this finding as a possible geographical risk factor to be analyzed in another study. 2020-10-21T00:00:00Z
