Mouse barley awn (Hordeum murinum) migration induced cystolithiasis in 2 male dogs

Javier del Ángel Caraza Carlos Cesar Pérez García Inmaculada Diez-Prieto María Belem García Rodríguez (2011)

Case Report

Two male dogs were presented with cystic uroliths composed of magnesium ammonium phosphate (struvite). Each had an atypical nidus, a mouse barley awn (Hordeum murinum). To our knowledge, this is the first report of grass awns located in the bladder lumen of dogs. The composition of uroliths and the pathophysiology of grass awn migration to the urinary bladder are discussed.

The authors are grateful for the help of Dr. Antonio Javier Sánchez-Rodríguez (Service of Microscopy of Universidad de León) for the scanning electron microscopy study, Prof. Felix Llamas and Prof. Carmen Acedo (Department of Botany of Universidad de León) for the grass awn identification and Dr. Edgardo Soriano-Vargas (CIESA, Universidad Autónoma del Estado de México) for his editorial assistance.

Xantinuria: una causa rara de urolitiasis en el gato

Javier del Ángel Caraza ISRAEL ALEJANDRO QUIJANO HERNANDEZ Inmaculada Diez_Prieto CARLOS PEREZ GARCIA CLAUDIA IVETH MENDOZA LOPEZ JOSE SIMON MARTINEZ CASTAÑEDA (2012)

Xanthinuria is a very rare disease in cats. Its etiology may have a genetic origin or may be due to an iatrogenic xan- thine-dehydrogenase inhibition that nally results in urolithiasis. The present work reports two cases of xanthine uro- lithiasis in European Shorthair unrelated male and female cats. Both uroliths were analyzed by stereoscopic microsco- py, infrared spectroscopy and scanning electron microscopy. Besides the report of these two clinical cases, a detailed pathophysiologic review and some updated recommendations for diagnosis and treatment for this condition were done.

La xantinuria es una patología que se presenta raramente en los gatos. Su etiología puede tener origen genético o de- berse a una inhibición yatrogénica de la enzima xantina deshidrogenasa, que generalmente se mani esta con urolitiasis. En este trabajo se informa el hallazgo de dos urolitos de xantina en dos gatos, un macho y una hembra, de raza Euro- pea de pelo corto, no emparentados. Los urolitos fueron analizados mediante microscopía estereoscópica, espectrosco- pía infrarroja y microscopía electrónica de barrido. Además de informar sobre estos casos clínicos, se hace una revisión detallada de la siopatología y de las recomendaciones actuales para el diagnóstico y manejo médico de esta patología.

Se agradece al Consejo Nacional de Ciencia y Tecnolo- gía de México (CONACyT) y al Programa de Mejora- miento del Profesorado de la Secretaria de Educación Pública de México 2011 (PROMEP-SEP), el apoyo complementario para la realización de este trabajo.

Analysis of lower urinary tract disease of dogs

CLAUDIA IVETH MENDOZA LOPEZ Javier del Ángel Caraza ISRAEL QUIJANO HERNANDEZ MARCO ANTONIO BARBOSA MIRELES (2017)

Estudio epidemiológico de las enfermedades del tracto urinario caudal en perros

Lower urinary tract diseases (LUTD) include different conditions that affect the urinary bladder, urethra and prostate. The objective of this study was to determine the frequency of different related diseases, to characterize the population affected, and to determine risk factors in dogs. The clinical cases were diagnosed with LUTD through physical examina- tion, and clinical laboratory and imaging studies. Male dogs had a greater predisposition to present a LUTD. Dogs from 3 months to 18 years with a median of 8 years were affected, and the most affected breeds were Poodle, Labrador, German shepherd, Schnauzer, Cocker Spaniel and Chihuahua. The LUTD presented with the following frequencies: bacterial uri- nary tract infection 34.02%; micturition disorders 22.68%; urolithiasis 20.61%; prostatic disease 14.43%; traumatic problems 8.24%. Sixty-seven per cent of the cases were specific diseases, such as uncomplicated and complicated bacterial urinary tract infections, urinary retention of neurologic origin and silica urolithiasis.

Canine urolithiasis in México

Trabajo presentado en el American College of Veterinary Internal Medicine Forum 2011. Junio 2011. Denver, Colorado. USA.

dogs in the worldwide, in which breed. iex. age. diet, some anatomical abnormalities, urinary tract infection, urine pH and some geographical and hereditary features in the populations studied have been implicated as risk factors. The effective long-term management of urolithiasis depends on identification and control of the pathophysiological mechanisms involved, which, in turn, depend on accurate knowledge of the mineral composition of the uroliths. The aim of this study was to determine for first occasion the main epidemiological data of canine urolithiasis in Mexico. This study was developed with 491 dogs with urolithiasis from 25 ofthe 33 states of the country.

This work has been partially supported by a project Waltham Foundation and the Consejo Nacional de Ciencia y Tecnología (CONACyT) of México.
