Objective To summarize the medical knowledge surrounding aardvarks to date, to describe the ophthalmic examination of a specimen with a chronic history of an upper eyelid lesion, of an assumed blind left eye, and to detail the anesthesia procedure performed. Procedure A 23‐year‐old aardvark was examined under general anesthesia and multiple ocular abnormalities were detected in the left eye (globe deviation, corneal opacities, iridodonesis, and aphakia). A thickening of the palpebral conjunctiva affecting the medial upper eyelid with erosion of the normal eyelid margin anatomy was identified. The adnexal lesion was resected by a wedge resection and histopathology was performed. Suture breakdown 3 days postoperatively required a second surgery, where buried sutures were used. The surgical techniques and postoperative care are discussed. Results The histopathology revealed mucosal hyperplasia and moderate neutrophilic and lymphoplasmacytic blepharitis. No causal organisms were identified. Following initial wound dehiscence and a modified surgical technique, the upper eyelid healed without complication and retained complete function. Conclusions The eyelid lesion involved a benign inflammatory and hyperplastic pathology of unknown etiology. Adjusting routine ophthalmic surgical techniques to wildlife and zoo animals can be challenging and complicated. It is important to understand the nature of the animals being managed, their circadian cycle, and habitat, to adjust and individualize the surgical approach, instrumentation, suture material, and perioperative treatment. 相似文献
OBJECTIVES: To investigate the relationships between food poverty and food consumption, health and life satisfaction among schoolchildren. DESIGN: Analysis of the 2002 Health Behaviour in School-aged Children (HBSC) study, a cross-sectional survey that employs a self-completion questionnaire in a nationally representative random sample of school classrooms in the Republic of Ireland. SUBJECTS: A total of 8424 schoolchildren (aged 10-17 years) from 176 schools, with an 83% response rate from children. RESULTS: Food poverty was found to be similarly distributed among the three social classes (15.3% in the lower social classes, 15.9% in the middle social classes and 14.8% in the higher social classes). It was also found that schoolchildren reporting food poverty are less likely to eat fruits, vegetables and brown bread, odds ratio (OR) from 0.66 (95% confidence interval (CI) 0.45-0.87) to 0.81 (95% CI 0.63-0.99); more likely to eat crisps, fried potatoes and hamburgers, OR from 1.20 (95% CI 1.00-1.40) to 1.62 (95% CI 1.39-1.85); and more likely to miss breakfast on weekdays, OR from 1.29 (95% CI 0.33-1.59) to 1.72 (95% CI 1.50-1.95). The risk of somatic and mental symptoms is also increased, OR from 1.48 (95% CI 1.18-1.78) to 2.57 (95% CI 2.33-2.81); as are negative health perceptions, OR from 0.63 (95% CI 0.43-0.83) to 0.52 (95% CI 0.28-0.76) and measures of life dissatisfaction, OR from 1.88 (95% CI 1.64-2.12) to 2.25 (95% CI 2.05-2.45). Similar results were found for life dissatisfaction in an international comparison of 32 countries. All analyses were adjusted for age and social class. CONCLUSIONS: Food poverty in schoolchildren is not restricted to those from lower social class families, is associated with a substantial risk to physical and mental health and well-being, and requires the increased attention of policy makers and practitioners. 相似文献
Swine may be examined to evaluate a disease state or a lowered economic performance or as a herd health consultation. As much of the examination as possible should be performed without handling the animal. A thorough history, evaluation of herd records, environmental examination, and herd examination should be performed prior to the evaluation of an individual animal. All necessary equipment should be available when starting the individual examination. The animals is then restrained and examined, and necessary samples are taken. Post-mortem examinations or slaughter house evaluations are a very frequent part of a health examination on swine. All samples taken should be in accordance with the standards of the laboratory that you use. You should work closely with the laboratory to obtain the best results. Physical examination of swine can be rewarding for the veterinarian as well as the producer. The most important aspect to remember is to have enough information and the proper equipment available to handle the animals for the minimal amount of time to gain the maximum benefits. Vietnamese pot-bellied pigs are similar to domestic swine in terms of their diseases and health but are dissimilar in management; pot-bellied pigs are frequently brought to the veterinarian for individual examinations. History is the most valuable part of the examination, followed by observation. Pot-bellied pigs prefer to be held securely with a hand under the chin and rump. The examination is conducted similarly to the examination of any companion animal. Chemical restraint often is necessary for sampling or minor surgical procedures. Owners should be consulted prior to the use of any restraint. This will help win their approval and confidence when working on their pets. While performing the physical examination, look at the pig's overall health as well as specific breed characteristics. Try to stay abreast of swine vaccination recommendations; you may be consulted in this regard. Most importantly, never forget even though they are pigs, pot-bellied pigs are companion animals and should be handled as such. 相似文献
After 3 years and 31 close flybys of Titan by the Cassini Orbiter, Titan was finally observed in the shocked solar wind, outside of Saturn's magnetosphere. These observations revealed that Titan's flow-induced magnetosphere was populated by "fossil" fields originating from Saturn, to which the satellite was exposed before its excursion through the magnetopause. In addition, strong magnetic shear observed at the edge of Titan's induced magnetosphere suggests that reconnection may have been involved in the replacement of the fossil fields by the interplanetary magnetic field. 相似文献
The precision of the disc diffusion protocols previously published by Alderman and Smith (Aquaculture 196 (2002) 211) was analysed in a seven-laboratory trial using Escherichia coli ATCC 25922 as the test strain. Discs containing seven antimicrobial agents were employed and 2899 zone size measurements were generated. The total data generated in the trial was used to quantify the intra- and inter-laboratory precisions. The study design also facilitated the investigation of the influence of the source of media and the source of discs on zone sizes. A smaller two-laboratory trial was employed to investigate the influence of incubation time of zone size.
The intra-laboratory precision was relatively high with the mean of the coefficients of variation calculated for each laboratory and each agent being 4.7%. In contrast, the inter-laboratory precision was very much lower with the mean of the values for each agent being 11.1%. Significant influences on zone size were detected for all three parameters of the protocol. Media source effects were particularly notable with respect to oxytetracycline and oxolinic acid discs, disc source effects with respect to ampicillin and sulphamethoxazole/trimethoprim discs and incubation times with the ampicillin and amoxycillin discs. ANOVA analysis of the total data set confirmed that inter-laboratory variation was the major factor influencing the low precision of the protocol.
The overall precision of the protocols used here was found to be significantly lower than that implied by the control limits associated with the same bacterium in other validated disc diffusion protocols. The implications of these results, for the further development of the protocols under investigation, are discussed. 相似文献
To evaluate the analgesic efficacy of Yamamoto New Scalp Acupuncture (YNSA) as an adjuvant for postoperative pain management in cats.
Study design
Prospective, randomized, blinded, clinical study.
Animals
Twenty cats aged (mean ± standard deviation) 25 ± 9 months and weighing 2.7 ± 0.6 kg undergoing ovariohysterectomy.
Methods
The cats were sedated with intramuscular (IM) ketamine (5 mg kg?1), midazolam (0.5 mg kg?1) and tramadol (2 mg kg?1). The cats were randomly distributed before induction of anesthesia into two groups of 10 cats each: group YNSA, in which bilateral basic D points were stimulated with a dry needle from 20 minutes prior to anesthetic induction to the end of the surgery; group Control, in which no acupuncture was applied. Postoperative analgesia was assessed at 1, 2, 4, 8, 12, 18 and 24 hours postextubation using an Interactive Visual Analog Scale and Universidade Estadual Paulista-Botucatu Multidimensional Composite Pain Scale (UNESP-Botucatu MCPS). Rescue analgesia was provided with IM tramadol (2 mg kg?1), and the pain scores were reassessed 30 minutes after rescue intervention. If the analgesia remained insufficient, meloxicam (0.2 mg kg?1 as a single dose) was administered IM. Data were analyzed using Student t-test, Fisher exact test, Mann–Whitney U test and Friedman test (p < 0.05).
Results
Significantly lower pain scores were observed in YNSA when compared with Control at 1–4 hours based on the UNESP-Botucatu MCPS scores. Although significant differences were not identified between groups requiring rescue analgesia, additional postoperative analgesia was administered to four of 10 cats in Control and no cats in YNSA.
Conclusion and clinical relevance
Perioperative YNSA resulted in decreased pain scores and a reduction in postoperative requirement for rescue analgesia in cats. This method should be considered a viable option as an adjuvant analgesic therapy for cats undergoing ovariohysterectomy. 相似文献
