Technetium-99m HMPAO-labeled leukocyte imaging compared with endoscopy, ultrasonography, and contrast radiology in children with inflammatory bowel disease.

Background: The purpose of this study was to evaluate retrospectively the value of leukocyte-labeled scintigraphy, ultrasonography, and contrast radiography compared with endoscopy in children suspected of having inflammatory bowel disease (IBD).

Methods: Twenty-eight children (17 boys; mean age, 10.2 years) with IBD based on standard colonoscopic, histologic, and radiologic criteria (16 with Crohn's disease, 5 with ulcerative colitis, 5 with nonspecific colitis, I with granulomatous disease, and I with Beh,cet's disease) were included.

Concordance between abdominal scintigraphy using technetium-99m hexamethylpropylene amine oxime-labelled leucocytes and ileocolonoscopy in patients with spondyloarthropathies and without clinical evidence of inflammatory bowel disease.

Objective: To study the concordance between abdominal scintigraphy using technetium-99m hexamethylpropylene amine oxime (99mTc-HMPAO)-labelled leucocytes (ASTLL) and ileocolonoscopy in patients with spondyloarthropathies (SpA) and without clinical evidence of inflammatory bowel disease (IBD).

Patients And Methods: Fifteen patients with SpA (European Spondylarthropathy Study Group 1991 criteria) without clinical evidence of IBD were studied prospectively with ASTLL and ileocolonoscopy.

Results: This cohort consisted of seven men and eight women aged 31.

Possible role of HLA in hepatotoxicity. An exploratory study in 71 patients with drug-induced idiosyncratic hepatitis.

Possible associations between particular human leucocyte antigen molecules and immunoallergic hepatitis have been suggested previously (HLA-A11 in halothane hepatitis, HLA-DR6 and DR2 in nitrofurantoin hepatitis, HLA-B8 in clometacin hepatitis). In this study the HLA haplotype was determined in 71 patients with idiosyncratic hepatitis due to different drugs. The prevalence of HLA-A11 was twice as high in the 71 patients in the study (23%) as in controls (12%), but p-values were not significant when corrections were made for the large number of comparisons (n = 39).

Glutaric acidemia type II. Heterogeneity in beta-oxidation flux, polypeptide synthesis, and complementary DNA mutations in the alpha subunit of electron transfer flavoprotein in eight patients.

We studied metabolic, polypeptide and genetic variation in eight glutaric acidemia type II (GA II) patients with electron transfer flavoprotein (ETF) deficiency. As measured by 3H-fatty acid oxidations in fibroblasts, beta-oxidation pathway flux correlated well with clinical phenotypes. In six patients with severe neonatal onset GA II, oxidation of [9,10(n)-3H]-palmitate ranged from 2% to 22% of control and of [9,10(n)-3H]myristate, from 2% to 26% of control.
