Small changes in T(4) dosage do not produce measurable changes in hypothyroid symptoms, well-being, or quality of life, despite the expected changes in serum TSH and markers of thyroid hormone action. These data do not support the suggestion that the target TSH range for the treatment of primary hypothyroidism should differ from the general laboratory range.

Total variation in AMH was 20%, and the majority of this was biological. Changes in AMH resulted in reclassification in 29% of women and occurred most frequently in those with low and reduced AMH. In cycling women, the variability in AMH should be considered by clinicians, especially if a result is close to a clinical cutoff.

Success rate and complications of adrenal vein sampling procedures before and after use of the adrenal vein sampling Accuracy Kit. Routine use of the adrenal vein sampling Accuracy Kit device for intraprocedural measurement of cortisol commenced in 2016. Results Technical success rate of adrenal vein sampling increased from 63% of 99 procedures to 90% of 48 procedures ( P = 0.0007) after implementation of the adrenal vein sampling Accuracy Kit. Failure of right adrenal vein cannulation was the main reason for an unsuccessful study. Radiation dose decreased from 34.2 Gy.cm (interquartile range, 15.8-85.9) to 15.7 Gy.cm (6.9-47.3) ( P = 0.009). No complications were noted, and implementation costs were minimal. Conclusions Point-of-care cortisol measurement during adrenal vein sampling improved cannulation success rates and reduced radiation exposure. The use of the adrenal vein sampling Accuracy Kit is now standard practice at our centre.

Background and Purpose-We sought to examine prospectively the relationship between asymptomatic carotid bruit and stroke in type 2 diabetes. Methods-We studied 1181 (91.3%) of a community-based sample of 1294 patients with type 2 diabetes. These patients had no history of cerebrovascular disease at recruitment during 1993-1996 and were followed until the end of January 2002. Hospital morbidity and death register data relating to cerebrovascular events were also available. Cox proportional hazards models were used to determine whether carotid bruit status was an independent predictor of stroke and to identify other significant cerebrovascular risk factors. Results-One hundred thirty-four patients (11.3%) suffered a first stroke during 6.5Ϯ2.2 (meanϮSD) years of follow-up.In the first 2 years after study entry, first stroke (nϭ45/1181; 3.8%) was strongly predicted by the presence of carotid bruit(s) after adjustment for known cardiovascular risk factors and other potentially confounding variables (hazard ratio, 6.7; 95% CI, 3.0 to 14.9; PϽ0.001). Between 2 years and census, first stroke (nϭ89/1083; 8.2%) was not associated with carotid bruit(s) (Pϭ0.97). Age and diastolic blood pressure were other determinants of stroke in the first 2 years, while age, atrial fibrillation/flutter, and microalbuminuria were independent predictors of subsequent stroke. Conclusions-Type 2 diabetic patients found to have incidental carotid bruits have Ͼ6 times the risk of first stroke in the first 2 years than patients without a bruit and should receive intensified management of vascular risk factors. Carotid imaging with a view to surgical intervention in these patients remains controversial.
