Coronary bypass graft fate: angiographic grading of 1400 consecutive grafts early after operation and of 1132 after one year.

All 1400 coronary bypass grafts, in 409 survivors of 414 patients undergoing 440 consecutive bypass operations, were selectively opacified in multiplane cineangiograms prior to hospital discharge and 1132 (81%) were restudied at one year. Grafts were graded A (excellent), B (fair) or O (occluded) by separate assessment of proximal and distal anastomoses and bypass trunks. In early graft studies 89% were patent (A and B), 79% graded A; at one year, 81% were patent, 74% graded A. Circumflex-marginal grafts fared less well early, but similarly late, compared with other grafts. Of all grafts graded B early, 37% became A, 39% remained B and 24% were occluded at one year; 90% of early graded A grafts remained so, 4% became B and 6% occluded; the grading system seems to have had useful predictive value. Distal anastomosis defects dictated early B grading in 81.3% of cases, trunk defects in 12.5% and proximal anastomosis defects in 2.7%. Trunk defects carried a worse prognosis for occlusion than did distal anastomosis defects. Side-to-side, vein-coronary anastomoses had a significantly higher patency rate than terminal end-to-side coronary anastomoses with the same veins.

Missed opportunities for a diagnosis of acute otitis media in Aboriginal children.

OBJECTIVE: Severe otitis media and its sequelae are common in rural and remote Aboriginal children. Identification of acute otitis media (AOM) is likely to reduce the number of children who go on to develop chronic suppurative otitis media and associated complications. The aim of this study was to compare the diagnoses made by researchers with that documented in the medical records of children admitted to the paediatric isolation ward of the Royal Darwin Hospital, Darwin, Northern Territory. METHODS: Children aged <8 years admitted to Royal Darwin Hospital were eligible for assessment by pneumatic otoscopy, video-otoscopy and tympanometry. A diagnosis was made for each child according to the state of their worst ear. Comparisons were made between the researcher diagnoses of ear disease and those documented in the hospital notes by medical staff. RESULTS: Thirty-one children were enrolled during 32 admissions. Most were aged <2 years, Aboriginal, and resided in remote communities. Sixty-one video-otoscopic assessments were attempted and sufficiently good images to allow diagnosis were obtained in 105 of 122 ears. Acute otitis media was diagnosed by the research team in 20 of 32 child admissions. Of 29 children who had ear examinations documented by hospital staff, only seven had a diagnosis of AOM recorded. Overall, the research team were almost three times more likely to make this diagnosis (relative risk 2.9, 95% confidence interval 1.6, 5.2). This difference was unlikely to have occurred by chance (P = 0.0002, McNemar's Chi-squared test). CONCLUSIONS: In this small study, young Aboriginal children with clear bulging of their tympanic membrane were not diagnosed with AOM by medical staff. Further training in diagnosis, including cleaning of the ear canal, may lead to more accurate assessment and appropriate recommendations for ongoing management.
