ABSTRACT

Painful procedures can affect the function of innate immune cells, such as neutrophils and macrophages, increasing the risk of infectious diseases. The present work aimed to verify if the analgesics flunixin meglumine or ketoprofen can attenuate the pain/discomfort of newborn lambs submitted by elastration tail docking and thereby avoid the impairment of blood granulocytes function. Twenty-one neonate lambs were divided into three treatments: the control group (n=7), not subjected to caudectomy; the flunixin group (n=7), subjected to caudectomy under local anesthesia and analgesia with two doses of flunixin meglumine; and the ketoprofen group (n=7), subjected to caudectomy under local anesthesia and two doses of ketoprofen. Pain indicators were observed by pain posture score (PS), the number of vocalizations (V), frequency of the movement of the ears (EF), and respiratory rates (RR), observed by a 10 minutes videos for each time points: -15min, 6h, 48h, and 144h. At the same time points, the reactive oxygen species (ROS) production and phagocytosis of blood granulocytes were measured by flow cytometry. At 6h after caudectomy, there was a pain indicator increase (RR, V, and PS), a blood granulocyte percentage increase, and a granulocytes phagocytosis reduction for both groups. At 48h, the ketoprofen group spend more time in pain posture and, at 144h, they exhibited a ROS production granulocyte reduction without signs of pain. We conclude the flunixin meglumine and ketoprofen did not prevent the acute pain/discomfort caused by caudectomy, because the groups showed a pain behavior and impaired of the innate immune response however, the flunixin meglumine was effective in controlling the chronic pain and their effects on blood granulocytes function in compare ketoprofen.(AU)

ABSTRACT

PURPOSE: In this study we evaluate the diagnostic accuracy of renal pelvic dilatation for detecting infants with prenatal hydronephrosis who will need surgical intervention for ureteropelvic junction obstruction during followup. MATERIALS AND METHODS: Between 1999 and 2010, 371 newborns diagnosed with isolated prenatal hydronephrosis were prospectively followed. The main event of interest was the need for pyeloplasty. Diagnostic odds ratio, sensitivity, specificity and diagnostic accuracy (assessed by AUC) of fetal renal pelvic dilatation and postnatal renal pelvic dilatation were evaluated. RESULTS: A total of 312 patients were included in the analysis and 25 (7.5%) infants underwent pyeloplasty. The diagnostic performance for detecting the need for pyeloplasty was excellent for all ultrasonography measurements. The AUC was 0.96 (95% CI 0.92-0.98) for fetal renal pelvic dilatation, 0.97 (95% CI 0.95-0.98) for postnatal renal pelvic dilatation and 0.95 (95% CI 0.92-0.97) for the Society for Fetal Urology grading system. A cutoff of 18 mm for fetal renal pelvic dilatation and a cutoff of 16 mm for postnatal renal pelvic dilatation had the best diagnostic odds ratio to identify infants who needed pyeloplasty. Considering a diagnosis to be positive only if fetal renal pelvic dilatation was greater than 18 mm and postnatal dilatation was greater than 16 mm, sensitivity was 100% and specificity was 86% (95% CI 80.7-89.9). CONCLUSIONS: Our findings suggest that the combination of fetal and postnatal renal pelvic dilatation is able to increase the diagnostic accuracy for detecting infants who need a more comprehensive postnatal investigation for upper urinary tract obstruction.
