Many ways of detecting hip instability in the newborn infant exist, including a history of risk factors, clinical examination and ultrasound. We investigated our practice of 'at risk' screening using subjective, dynamic and static, ultrasound, followed by radiographic evaluation at 12 months. We found that the average age at presentation was 71 days, with the most common reason for referral being a clicking hip. None of the hips deemed stable under review deteriorated, and all those considered normal at first visit had a normal radiograph at 12 months. Abnormal radiographs were found in all the other groups.
High-resolution real time sonography was used to evaluate patients with suspected primary hyperparathyroidism. A total of 12 consecutive patients was scanned pre-operatively. The sensitivity of the procedure was 92% and the specificity 97%. In our hospital sonography is the procedure of choice for localizing enlarged parathyroid glands prior to surgical exploration.
In our study all patients presenting with biochemical evidence of primary hyperparathyroidism and raised parathormone levels did in fact undergo pre-operative localization with ultrasound.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
