Diarrhea is an important cause of morbidity in neonatal llamas and alpacas. Diarrhea may be multifactorial in etiology including management and nutritional factors as well as a variety of pathogens. Most of the pathogens involved affect other livestock species and some have host-adapted strains. However, the clinical signs, their expected severity and age of onset of disease varies between species in some cases. The most common pathogens causing diarrhea in neonatal camelids are coronavirus, Escherichia coli (E. coli), Cryptosporidium spp., Giardia spp. and coccidia. The purpose of this paper is to review the available literature on neonatal diarrhea in camelids and to present clinical data from 55 cases seen at The Ohio State University.
This study analysed news media content to examine the role played by celebrity drug use in young people's perceptions of drug use. We know that young people have access to discourses of drug use through music and other media which may emphasise short term gains (of pleasure or sexual success) over longer term health and social problems. This study goes beyond a simple modelling approach by using Media Framing Analysis (MFA) to take an in-depth look at the messages themselves and how they are 'framed'. New stories about Amy Winehouse's drug use were used and we conducted focus groups with young people asking them questions about drugs, celebrity and the media. Frames identified include: 'troubled genius', 'losing patience' and 'glamorization or gritty realism'. Initially, the press championed Winehouse's musical talent but soon began to tire of her recklessness; the participants tended to be unimpressed with Winehouse's drug use, characterising her as a promising artist who had 'gone off the rails'. Young people were far more critical of Winehouse than might be expected demonstrating that concerns about the influence of celebrity drug use and its impact on future health risk behaviour among young people may have been oversimplified and exaggerated. This study illustrates the need to understand young people and their frames of reference within popular culture when designing drug awareness information relevant to them. Furthermore, it indicates that critical media skills analysis may contribute to health risk education programmes related to drug use.
This article attempts to cover the most common problems likely to present in neonatal crias and to give guidance on how to approach these cases, particularly how to stabilize the acute presentation of a sick neonate. It is impossible to cover every eventuality and it is important to keep an open mind when evaluating and treating sick neonatal camelids. Despite the often moribund presentation of sick neonatal crias, they may be highly rewarding to treat, although hospitalization and 24-hour care is recommended.
The aim of this study was to examine the behavioural and cranial/spinal responses of alpacas culled by captive bolt shooting and the resulting pathophysiology of captive bolt injury. Ninety-six alpacas were shot (103 shots) in a range of locations with a penetrating captive bolt gun (CBG). Ten (9.8%) alpacas were incompletely concussed following the first shot. No animals required more than two shots. Incorrectly placed shots accounted for all of the animals that displayed signs of sensibility. Damage to the thalamus, hypothalamus, midbrain, medulla, cerebellum, parietal and occipital lobes were significantly associated with decreasing odds of incomplete concussion. In conclusion, the study confirmed that CBG stunning can induce insensibility in alpacas and suggests that the top of the head (crown) position maximises damage to structures of the thalamus and brainstem.
An increasing number of practitioners in the UK are being asked to see South American camelids (mainly llamas and alpacas). There are now just under 28,000 registered alpacas in the country, mostly concentrated in the south, although they are scattered across the regions. It is the veterinary surgeon's responsibility to take steps to familiarise themselves with any species under their care. This article considers some of the more common disease presentations that are seen in camelids in the UK. A second article, to be published in a subsequent issue of In Practice, will focus on common disease presentations seen in young camelids.
SHJL should be considered as a differential diagnosis in alpacas with thoracic limb lameness. Luxation may occur more frequently in males. A closed reduction technique may be used successfully to treat acute luxations. Extracapsular stabilization by use of the lateral extracapsular tension band suture technique was successful for treatment of recurrent SHJL and SHJL that could not be reduced via closed reduction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
