An intelligent framework for medical image retrieval using MDCT and multi SVM.

BACKGROUND: Volumes of medical images are rapidly generated in medical field and to manage them effectively has become a great challenge. This paper studies the development of innovative medical image retrieval based on texture features and accuracy. OBJECTIVE: The objective of the paper is to analyze the image retrieval based on diagnosis of healthcare management systems. METHODS: This paper traces the development of innovative medical image retrieval to estimate both the image texture features and accuracy. The texture features of medical images are extracted using MDCT and multi SVM. Both the theoretical approach and the simulation results revealed interesting observations and they were corroborated using MDCT coefficients and SVM methodology. RESULTS: All attempts to extract the data about the image in response to the query has been computed successfully and perfect image retrieval performance has been obtained. Experimental results on a database of 100 trademark medical images show that an integrated texture feature representation results in 98% of the images being retrieved using MDCT and multi SVM. CONCLUSION: Thus we have studied a multiclassification technique based on SVM which is prior suitable for medical images. The results show the retrieval accuracy of 98%, 99% for different sets of medical images with respect to the class of image.

Inspection of lymph nodes for caseous lymphadenitis and its effect on the density of microbes on sheep carcasses.

This study aimed to measure the amount of microbial contamination caused by inspecting the lymph nodes of adult sheep carcasses for caseous lymphadenitis (CLA). Surface swabs from carcasses pre-inspection (N=296) and post-inspection (N=296) were obtained for enumeration of indicator organisms at three commercial abattoirs. At the scapular site, inspection doubled the probability of detecting E. coli (Pr before=0.35, Pr after=0.67) and increased the expected count of E. coli from 2 cfu/cm² to 13 cfu/cm². Inspection at the rump site increased the probability of detecting E. coli by 1.1 times (Pr before=0.84, Pr after=0.93) and increased the expected count from 32 cfu/cm² to 45 cfu/cm². Effects were also observed for Enterobacteriaceae and total viable count. The findings show that routine inspection of adult sheep carcasses for CLA has a detrimental impact on carcass microbiological traits.

Analgesia pós-operatória com metadona em gatos: administração epidural e intramuscular / Postoperative analgesia of methadone in cats: epidural and intramuscular administration

Compararam-se os efeitos analgésico, sedativo e neuroendócrino decorrentes da administração epidural e intramuscular da metadona em gatas submetidas à ovariossalpingoisterectomia (OSH). Todos os animais foram tranquilizados com acepromazina, 0,1mg kg-1 IM, seguindo-se a indução e manutenção anestésica com tiopental sódico, 12mg kg-1 IV, e halotano, respectivamente. Após a estabilização anestésica, os animais foram distribuídos em três grupos, com oito animais cada, tratados com metadona pela via epidural (EP) ou intramuscular (IM) 0,2mg kg-1, respectivamente, ou com solução salina (S) 0,2mL kg-1. Foram avaliados: graus de analgesia e de sedação, necessidade de analgesia de resgate, efeitos adversos e concentração sérica de cortisol. Os graus de analgesia e de sedação e o cortisol não diferiram entre os tratamentos. Analgesia de resgate foi administrada quatro, nove e 11 vezes nos tratamentos EP, IM e S, respectivamente. Nos tratamentos IM e S, a suplementação analgésica foi necessária a partir da primeira hora pós-cirúrgica, enquanto no tratamento EP, somente a partir da terceira hora após a OSH. Conclui-se que a administração de metadona pela via epidural resulta em menor quantidade do analgésico pós-operatório, e que a analgesia é mais prolongada quando comparada à obtida pela via intramuscular, em gatas submetidas à OSH.

The aim of this study was to investigate the analgesic, sedative and neuroendocrine effects of epidural (EP) and intramuscular (IM) methadone in cats submitted to ovariohysterectomy. The pre-anesthetic medication was acepromazine (0.1mg kg-1, IM) followed by induction of anesthesia with intravenous thiopental, 12mg kg-1, and anesthesia maintenance with halothane. After anesthesia stabilization the cats were randomly assigned to three groups of eight animals each and received EP or IM methadone, 0.2mg kg-1 diluted with saline to 0.2mL kg-1, EP and IM, respectively, or a saline placebo (S), 0.2mL kg-1. Pain measurements, degree of sedation, rescue analgesia requirements, adverse effects and serum cortisol concentration were recorded. Cortisol, pain and sedation scores did not differ among the groups. Rescue analgesia was administered 4, 9 and 11 times in the EP, IM and S treatment, respectively. In the IM and S rescue analgesia treatments were required early (first hour postoperative), whereas in the EP treatment, additional analgesics were required after the third hour postoperative. In conclusion, methadone epidural reduced the postoperative analgesic requirements and produced longer analgesia when compared to intramuscular administration in cats undergoing ovariohysterectomy.
