Retroflexão de bexiga: relato de caso em Blastocerus dichotomus (Cervo-do-Pantanal)

A retroflexão de bexiga foi objeto de estudo em cervídeo atendido no Hospital Veterinário da FCAV-Unesp-Jaboticabal-SP. Uma fêmea gestante do criatório da Faculdade apresentou prolapso de bexiga e de reto. A cesariana foi efetuada, porém sem sucesso para ambos. Após esse procedimento, o animal foi sacrificado devido ao comprometimento total da bexiga.

Comparative study of epidural xylazine or clonidine in horses

Objective To evaluate the cardiorespiratory and behavioural effects of epidural xylazine (XYL) or clonidine (CLO) in horses.Study design Blinded, randomized experimental study.Twelve healthy Arabian yearling horses weighing 117-204 kg were randomly allocated into two groups: XYL (n = 6) and CLO (n = 6).Methods An epidural catheter was inserted and a facial arterial catheter was placed and the next day the horses were restrained in stocks. Baseline values for heart (HR) and respiratory (RR) rates, arterial pressure and behavioural responses were evaluated before (TO) and 10, 20, 30, 45, 60, 90 and 120 minutes after epidural injection (T10-T120). The horses received 0.2 mg kg(-1) of XYL or 5 mu g kg(-1) CLO; adjusted to (3.4 + (body weight in kg x 0.013) mL with saline. Data were analysed by the Kolmogorov-Smirnov test, one-way ANOVA with repeated measures, and one-way ANOVA followed by a Student-Newman-Keuls test or Fisher's exact test, as necessary. Significance was set at p <= 0.05.Results Sedation and ataxia were seen at T10, persisting until T120 in four and three horses, respectively, in XYL and all horses in CLO respectively. Two XYL and one CLO horses became recumbent at T45 and T25 respectively. Penile prolapse occurred in four of five males at T30 and T45, in the XYL and CLO groups, respectively, resolving by T120. Tail relaxation was present from T10 to T120 in all horses in XYL and in four horses in CLO. Head drop was observed from T20 to T60 and from T10 to T120 in XYL and CLO respectively. Respiratory rate decreased significantly only at T45 in the CLO group. Heart rate and arterial blood pressure remained stable.Conclusions and clinical relevance Epidural CLO and XYL produce similar cardiorespiratory and behavioural changes but neither would be safe to use clinically at the doses used in this study.

Urinary bladder washings in autopsies. A cytopathologic study of 63 cases

The sediment from urinary bladder washings from 63 consecutive autopsies was cytologically studied in order to achieve a better understanding of the changes in urothelial cells collected from hospital populations. The observed alterations were correlated with alterations in the urinary system and with therapy preceding death. The specimens obtained were of good quality. In 39.7% of the cases, the sediment contained giant superficial multinucleated cells. Three of nine cases previously subjected to radiation or chemotherapy showed atypical urothelial cells. In three cases with immunosuppression, there was cytologic evidence of subclinical infection by polyomavirus, and virus particles were identified by electron microscopy of the vesical mucosa. The study of the smear background offered additional information: the sediment contained hyaline or hematic or hyaline-cellular casts in 17.4% of the cases, in all of which there were renal tubulopathies when the kidney sections were studied. The method is useful for a good evaluation of the autopsy as well as for training in urinary cytopathology.

The comparative efficacy of yohimbine and atipamezole to treat amitraz intoxication in dogs

This study compared the efficacy of yohimbine with atipamezole, a new α2-adrenergic antagonist, to treat canine amitraz intoxication. Thirty dogs were divided equally into 3 groups (A, AY, and AA). Group A received 2.5% amitraz iv at 1 mg/kg; Group AY received the same dose of amitraz followed 30 min later by 0.1 mg/kg (2 mg/mL) yohimbine iv; and Group AA received the same dose of amitraz followed 30 min later by 0.2 mg/kg (5 mg/mL) atipamezole iv. Temperature, heart rate, respiratory frequency, mean arterial pressure, degree of sedation, mean time of tranquilization and diameter of pupils were monitored for 360 min. Sedation, logs of reflexes, hypothermia bradycardia, hypotension, bradypnea and mydriasis were observed in Group A, with 3rd eyelid prolapse, increased diuresis and vomiting in some animals. Yohimbine reversed all alterations induced by amitraz, but induced significant cardiorespiratory effects such as tachycardia and tachypnea. Atipamezole was a useful antagonist for amitraz, with less cardiorespiratory effects, suggesting its potential role as an alternative treatment of amitraz intoxication in dogs.

Ocorrência de infecção urinária em pacientes de um hospital universitário

Infection in hospitals is a serious problem for the Public Health System. It is responsible for the increasing number of hospital deaths, as well as the longer time patients may have to stay in hospital, raising the costs of confinement more and more. The most common hospital infection is urinary tract infections (UTI), the use of the urinary catheter being the main risk factor. The aim of this study was to evaluate the profile of UTI among hospitalized patients in a University Hospital in Brazil, from October to December 2003. Out of 271 samples of urine checked, 51 were positive, 27 of these from patients having community-acquired UTI and 24 whose infection originated in the hospital. The community-acquired UTIs were more frequent in female patients (63%). The highest incidence of infection was caused by Escherichia coli (74%), especially in patients aged from 0 to 15 (37%). The episodes of hospital-acquired infection happened, in the main, in male patients aged above 50 (68%) who were using a lasting vesical catheter; in this group of patients the infection was frequently caused by E. coli (29.1%) and Klebsiella spp. (29.1%). E. coli and Klebsiella pneumoniae exhibited strong resistance (62.5%) to trimethoprim-sulfamethoxazole, as well as to ampicillin, showing that these drugs should not be used to cure UTIs in this institution.

Prolapso da glândula da terceira pálpebra em cão -relato de caso

The updating of the of the prolapse of the third eyelid gland treatment in the literature is pertinent, due to the different surgical techniques for his resolution, with advantages and disadvantages. The work aimed to report the Moore technique in surgical treatment of the bilateral prolapse of the third eyelid gland in a female dog with bilateral entropion, six months, Shar-Pei breed, attended in the Veterinary Hospital School, Mozambique. The Moore technique showed good results and if the bilateral entropion was not a spastic type, was able to do the both surgeries in same day. The surgery using the Moore technique continues easy to learn, more simple to do and does not affect the third eyelid mobility.
