Food sensitivity in cats with chronic idiopathic gastrointestinal problems.

The objectives of this study were to investigate the prevalence of food sensitivity in cats with chronic idiopathic gastrointestinal problems, to identify the food ingredients responsible, and to characterize the clinical features. Seventy cats that presented for chronic gastrointestinal signs underwent diagnostic investigation. Fifty-five cats had idiopathic problems and were entered into the study. Diagnosis of food sensitivity was made by dietary elimination-challenge studies by using commercial selected-protein diets as the elimination diet. Sixteen (29%) of the 55 cats with chronic idiopathic gastrointestinal problems were diagnosed as food sensitive. The clinical signs of another 11 cats (20%) resolved on the elimination diet but did not recur after challenge with their previous diet. The foods or food ingredients responsible for the clinical signs were dietary staples. Fifty percent of affected cats were sensitive to more than 1 food ingredient. The clinical feature most suggestive of food sensitivity was concurrent occurrence of gastrointestinal and dermatological signs. Weight loss occurred in 11 of the affected cats, and large-bowel diarrhea was more common than small-bowel diarrhea. Assay of serum antigen-specific immunoglobulin E (IgE) had limited value as a screening test, and gastroscopic food sensitivity testing was not helpful. In conclusion, adverse reactions to dietary staples were common in this population of cats, and they responded well to selected-protein diets. Diagnosis requires dietary elimination-challenge trials and cannot be made on the basis of clinical signs, routine clinicopathological data, serum antigen-specific IgE assay, gastroscopic food sensitivity testing, or gastrointestinal biopsy.

Hong Kong patients' experiences of intensive care after surgery: nurses' and patients' views.

This study was designed to explore the lived experience of patients after elective surgery when they were being cared for in a surgical intensive care unit (ICU) in the immediate post-operative period. A phenomenological approach using unstructured interviews was employed and 10 ICU nurses and 10 patients were recruited for the study. Thematic data analysis was used. Most of the nurses believed that patients had memories of their ICU stay. Two clear categories emerged from the nurses' responses: 'perceptions of the feelings experienced by the patients' and 'perceptions of what patients experienced as support'. The nurses expressed that patients had feelings related to anxiety, pain and tiredness and they were frightened by the environment and the unknown. The nurses provided support to the patients by pre-operative visits, continuous and repeated explanation, encouraging family visits and ensuring adequate pain relief and sleep. All the patients could remember at least some of what happened during their stay in ICU. The 2 main categories which emerged from patients' responses were 'feelings experienced' and 'needs during the stay'. The patients recalled the feeling of anxiety about the reason for admission and a feeling of being safe in ICU. Six patients suffered from moderate to severe pain during movement and procedures and 2 patients complained of sleeping problems. They appreciated the preoperative visit and preferred the open unit design and flexible visiting hours. The four sub-categories: pain, sleep, pre-operative visits and family visits are discussed in detail and are reviewed in the light of other studies to compare the results. Ideas for nursing interventions to help overcome these problems are outlined and recommendations for future research are presented.

Thrombogenicity of dietary milkfat, fish oil and hydrogenated coconut oil in a pig model.

Abstract Extract Several indicators of thrombosis and thrombolysis were measured in four groups of 16 pigs fed for 10 weeks on either a low fat basal ration or rations containing 10% anhydrous milkfat (AMF), 10% fish oil (MaxEPA), or 10% hydrogenated coconut oil (HCO). At the end of the feeding period, pigs on the three test fat/oil rations were subjected to balloon angioplasty of both femoral arteries. Thrombus size at the site of injury was measured both morphometrically and using autologous blood platelets labelled with (99)Tc-HMPAO (technetium - "Deretec").

Malignant catarrhal fever in a swamp buffalo (Bubalus bubalis) calf in New Zealand.

Malignant catarrhal fever was diagnosed in a newly imported swamp buffalo calf. This disease is prevalent in deer and cattle in New Zealand and causes sporadic losses in these species. The disease is recognised as a problem in buffaloes overseas and this paper records the first case in a swamp buffalo in New Zealand.
