RESUMEN

BACKGROUND: Many studies have demonstrated that dimercaptosuccinic acid (DMSA) scintigraphy is the most sensitive diagnostic method in the identification of irreversible renal lesions (scars) in children with previous episodes of acute pyelonephritis (APN). This study assessed the reliability of ultrasound in identifying reflux nephropathy in children with acute pyelonephritis with or without vesicoureteric reflux (VUR). METHODS: Eighty children (45 female and 35 male, age range 5 months to 10 years, average age 2 years 1 month) with a positive history for at least one episode of APN participated in this study. All children underwent voiding cystourethrography, DMSA scintigraphy 4 to 8 months after the most recent episode of APN, and an ultrasound test evaluation less than 2 months after DMSA scintigraphy. RESULTS: Voiding cystourethrograms showed VUR in 52 children (68%); 13 of these were bilateral, for a total of 65 refluxing kidney units of the 154 (42%) evaluated; DMSA scintigram was normal for 108 of 154 kidneys (70%). Of the 65 kidneys with VUR, DMSA scintigram displayed normal findings in 29 cases (45%) and pathologic findings in 36 (55%). In the 79 nonrefluxing kidneys, DMSA scintigram was normal in 69 cases (87%). The relative risk of scarring in VUR kidneys is 2.6. The ultrasound study recorded a maximum longitudinal diameter between the 5th and 95th percentiles in 80 of 89 (81%) kidneys without VUR and in 21 of 65 (32%) with VUR. A significant correlation was found between maximum longitudinal diameters and DMSA scintigraphic findings in kidneys with VUR and those without VUR, respectively. CONCLUSION: This study establishes that ultrasound scans, by means of a simple and reproducible measurement technique, maximum longitudinal diameter, have a predictive value with regard to the presence of scars, with few exceptions. This finding, in our opinion, could lead to a decrease in the number of invasive procedures, in particular DMSA scan, in patients with APN.

RESUMEN

Twenty-five patients treated surgically for gastrointestinal carcinomas (16 rectum-sigmoid colon, 6 colon, 3 stomach) were investigated by immunoscintigraphy (IS) using 111In-labelled anti-CEA antibody (mouse monoclonal F023C5) F(ab')2 fragments in order to visualize questionable abdominopelvic recurrences (excluding the liver). Fifteen (60%) patients showed a rise in serum CEA levels above 5 ng/ml. Planar scans and emission computed tomographic (ECT) imaging were carried out without reference to the results of computed tomographic (CT) scans and gastrointestinal endoscopic examinations done 1-2 weeks before IS. Final diagnoses were based on biopsies and autopsies (13 cases) or on follow-up findings over at least 2 years (12 cases). Sixteen patients had a final diagnosis of recurrent malignant disease in the extrahepatic abdomen or pelvis. Of these, six were correctly diagnosed by both IS and conventional diagnostic procedures, six by IS only and two by conventional methods only. Two tumour recurrences remained undetected by both diagnostic approaches. However, five tumour recurrences were detected by IS more than 4 months earlier than by any other diagnostic procedures performed during clinical follow-up. Of the nine disease-free patients (disregarding the liver) three were correctly identified by both IS and the other diagnostic methods, four by IS only and two by conventional diagnostic procedures only. Overall sensitivity (75%) and specificity (89%) of 111In-IS were higher than figures obtained using CT scanning and endoscopy (50% and 78% respectively). True positive IS was observed in 6/15 (40%) CEA seropositive patients and in 6/10 (60%) CEA seronegative patients.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

More than 600 full-time employed care givers of older family members reported the impact of care giving on their work performance. While a large proportion reported a minimal negative impact on work performance, this impact was positively correlated with the extent of their care giving burden. When asked what employers could do to help, employees most often requested flexibility.
