Scrotal Castration as a Safe and Effective Means of Male Canine Sterilization

Woodruff, Kimberly A 11 May 2013 (has links)
For years, a prescrotal technique has been the only accepted method of male dog sterilization, as dogs are considered to be “scrotal conscious.” The prevailing thought has been that a scrotal incision will cause more complications including swelling and induction of self-trauma. There is, however, little in the scientific literature that confirms or contradicts this thinking. In this study 437 apparently healthy male dogs over the age of 6 months were randomly allocated into 2 treatment groups and castrated by either a prescrotal (n=206) or scrotal incision (N=231). Complications were recorded up to 72 hours following the procedure. The focus of this study is to evaluate the hypothesis that there are no differences between the prescrotal and scrotal technique. The method of castration was not found to be significantly associated with hemorrhage, pain or swelling. A reduced incidence in self trauma was associated with scrotal castrations.

Feline amputees : gait adaptations and welfare implications

Forster, Lyn January 2013 (has links)
This research focused on three areas of interest regarding feline amputees; owner perception of how their cats adapt to limb amputation, the possibility of phantom sensation, and changes in gait. In general owners felt their cats had an acceptable quality of life; however a proportion believed their cat experienced pain. Anecdotally, owners reported that their cats continued to attempt to use the missing limb following amputation. This prompted the investigation of noninnate forelimb behaviours potentially indicative of phantom sensation; such behaviours apparently persist for months or years after amputation. The impact of phantom sensation on feline welfare is not known, although in humans phantom sensation is a risk factor for phantom pain. Alterations in gait and posture in humans are associated with pain and osteoarthritis. The kinetic changes in feline gait were assessed using a pressure sensitive walkway; this provided its own challenges as the software was designed for large bipeds. As such, a proportion of this work was devoted to developing methods to reliably extract data for small quadrupeds. The results detail how feline amputees alter their weight distribution and paw placement when moving. Observation of amputee cats suggests that they move their limbs differently to those of normal cats, and this was confirmed in a kinematic study using markers to track the motion of each limb. Prior to this research very little was known about how cats coped with limb amputation. The results will better inform the veterinary profession and owners of feline amputees about expected changes, and potentially inform future work on the impact of limb amputation on the welfare of cats. On balance, although there may be some areas of concern, the welfare of cats is acceptable following amputation.

Infection and haemorrhagic complications associated with skin cancer surgery

Dixon, Anthony Unknown Date (has links)
Over four years from 2002 to 2006, a series of concomitant studies were undertaken to explore the complications and outcomes of skin cancer surgery. Specifically: 1. Through prospective studies, to identify risk factors for bleeding and infectious complications following skin surgery. 2. To determine through a randomized controlled trial whether mupirocin ointment versus paraffin ointment versus no ointment on a wound following skin closure affords the patient benefit. 3. To determine whether patients are at increased post operative bleeding risk should they remain on warfarin and / or aspirin prior to skin surgery. 4. To develop and then trial a novel approach (reducing opposed multilobed [ROM] flap) for below knee wound closures that may reduce the incidence of skin surgery complications on the leg and foot. 5. To investigate whether patients who suffer surgical complications are less likely to be satisfied with the service provision.

The haemostatic defect of cardiopulmonary bypass

Linden, Matthew D. January 2003 (has links)
[Truncated abstract] Cardiac surgery involving cardiopulmonary bypass is a complex procedure that results in significant changes to blood coagulation, fibrinolytic biochemistry, platelet number and function, and the vasculature. These are due to pharmacological agents which are administered, haemodilution and contact of the blood with artificial surfaces. Consequently there are significant risks of thrombosis and haemorrhage associated with this procedure. The research presented in this thesis utilises in vitro, in vivo, and a novel ex vivo model to investigate the nature of the haemostatic defect induced by cardiopulmonary bypass. The components studied include the drugs heparin, protamine sulphate, and aprotinin, different types of bypass circuitry (including heparin bonded circuits) and procedures such as acute normovolaemic haemodilution. Patient variables, such as Factor V Leiden, are also studied. Each of these components is assessed for the effects on a number of laboratory measures of haemostasis including activated partial thromboplastin time, prothrombin time, activated protein C ratio, antithrombin concentration, heparin concentration, thrombin-antithrombin complex formation, prothrombin fragment 1+2 formation, markers of platelet surface activation and secretion, activated clotting time, haemoglobin concentration and coagulation factor assays.

Obesidade grau III : considerações sobre complicações clínicas e tratamento cirúrgico

Rizzolli, Jacqueline January 2005 (has links)
A obesidade grau III ou também chamada obesidade mórbida é uma condição clínica freqüente e que vem apresentado crescimento progressivo, estando associada a elevadas taxas de morbi-mortalidade. Trata-se de uma doença de origem multifatorial, freqüentemente associada a comorbidezes, necessitando uma abordagem terapêutica que propicie redução de peso, melhora das doenças associadas e conseqüente melhora da qualidade de vida. O tratamento convencional deve ser sempre a primeira escolha, principalmente nos casos de inicio recente e sem antecedentes de tratamentos adequados prévios. A taxa de insucesso, contudo, é extremamente elevada, ocorrendo falha em mais de 90% dos casos. O tratamento cirúrgico atualmente é a alternativa com melhores resultados, porém com riscos de complicações a curto, médio e longo prazo, caso não seja realizado um rigoroso acompanhamento clinico, nutricional e psicológico em equipe multidisciplinar experiente. Esta revisão tem por objetivo discorrer sobre as morbidades associadas à obesidade grave, as opções de tratamento convencional e cirúrgico bem como riscos relacionados à persistência de um grande excesso de peso versus risco cirúrgico. / Morbid obesity is a frequent disease with a progressive increase in incidence and associated with high morbid and mortality rates. It is a multifactorial disease, and is usually associated with comorbidities. It is necessary specific treatment to reduce weight, to improve the comorbidities and obtain a better quality of life. The classic treatment, diet and exercise, should be the first choice, especially in cases of recent onset of severe obesity and poor quality previous treatments. Unfortunately, in more than 90% of the patients this kind of treatment will fail. Bariatric surgery is, nowadays, the best option of treatment, but has several risks of complications in the short, medium or long time followup, mostly in patients not followed by a specialized multidisciplinary team. This is a review about morbid obesity, comorbidities, options of treatment and the risks of stay severely obese versus surgical procedures.
