Laskoski L.M., Doria R.G.S., Avila L.G., Rocha T.G., Freitas S.H. de & Lacerda Neto J.C. [Paradoxal effect of the seizures treatment caused by physical exercise in a foal - Case report]. Efeito paradoxal do tratamento de manifestacoes convulsivas desencadeadas por exercicio fisico em uma potra - Relato de caso. Revista Brasileira de Medicina Veterinaria, 33(2):95-98, 2011. Rua Presidende Wenceslau Braz, numero 670, apart. 1101. Morada do Sol, Cuiaba, 78043-508. MT, Brasil. Email: lucianelaskoski@hotmail.comNeurological disturbs, in special seizures, are rare in adult horses and are normally observed in young animals in consequence of several diseases. A foal was admitted with neurological signs characterized by seizures during exercise. A maintenance protocol with anticonvulsants was not possible to establish therefore all the drugs had aggravated the seizures even with low dosages. Restriction of physical activity was the option, leaving the animal in stall until it had reached the maturity and at this time the neurological signs had stopped.

OBJECTIVE: To assess the effect of food restriction (FR) on hypertrophied cardiac muscle in spontaneously hypertensive rats (SHR). METHODS: Isolated papillary muscle preparations of the left ventricle (LV) of 60-day-old SHR and of normotensive Wistar-Kyoto (WKY) rats were studied. The rats were fed either an unrestricted diet or FR diet (50% of the intake of the control diet) for 30 days. The mechanical function of the muscles was evaluated through monitoring isometric and isotonic contractions. RESULTS: FR caused: 1) reduction in the body weight and LV weight of SHR and WKY rats; 2) increase in the time to peak shortening and the time to peak developed tension (DT) in the hypertrophied myocardium of the SHR; 3) diverging changes in the mechanical function of the normal cardiac muscles of WKY rats with reduction in maximum velocity of isotonic shortening and of the time for DT to decrease 50% of its maximum value, and increase of the resting tension and of the rate of tension decline. CONCLUSION: Short-term FR causes prolongation of the contraction time of hypertrophied muscles and paradoxal changes in mechanical performance of normal cardiac fibers, with worsening of the shortening indices and of the resting tension, and improvement of the isometric relaxation.

We examined the EEG of 88 patients with chronic renal failure (80 adults and 8 children) submitted to different types of treatment such as hemodialysis, peritoneal dialisys, renal transplantation, and ambulatory follow-up. The main alteration observed was diffuse disorganization of background activity. The following features were detected in decreasing order of frequency: low-voltage EEG, triphasic waves, abnormal waking reactions, and paradoxal alpha rhythm. The children showed abnormal alpha rhythm. The alterations induced by intermittent photic stimulation in our patients were minimal, and this was the main difference in relation to data reported by other authors in EEG studies on patients with chronic uremia.
