BACKGROUND Subclinical hypothyroidism (SCH) has been associated with ischemic heart disease (IHD); however, it is unknown whether treatment of SCH with levothyroxine sodium will reduce the risk of IHD. The aim of this study was to investigate the association between levothyroxine treatment of SCH with IHD morbidity and mortality. METHODS We used the United Kingdom General Practitioner Research Database to identify individuals with new SCH (serum thyrotropin levels of 5.01-10.0 mIU/L and normal free thyroxine levels) recorded during 2001 with outcomes analyzed until March 2009. ⋯ In contrast, in the older group there were 104 events in 819 treated patients (12.7%) vs 88 events in 823 untreated individuals (10.7%) (HR, 0.99; 95% CI, 0.59-1.33). CONCLUSIONS Treatment of SCH with levothyroxine was associated with fewer IHD events in younger individuals, but this was not evident in older people. An appropriately powered randomized controlled trial of levothyroxine in SCH examining vascular outcomes is now warranted.

Ectopic nephrogenic rest in the inguinal canal in a 6-month-old girl and a review of published studies.
Ectopic nephrogenic rests in the inguinal canal are rare. Usually discovered incidentally during surgery, these rests should raise the suspicion of an early extrarenal Wilms tumor. The differential diagnosis between the two entities is not only difficult but also essential, since they imply different treatment decisions. ⋯ Pathological diagnosis confirmed the diagnosis of an extrarenal hyperplastic nephrogenic rest. Five previous cases of ectopic nephrogenic rests originating in the inguinal canal have been reported, all of which were associated with a patent processus vaginalis. In this case, the nephrogenic rest was not associated with a congenital inguinal hernia.

Rapid response systems (RRSs) have been introduced to facilitate effective 'rescue' of seriously ill patients on hospital wards. While research has demonstrated some benefit, uncertainty remains regarding impact on patient outcomes. Little is known about the relationship between social contexts and the application of the RRS. ⋯ Locating a RRS within a pathway of care for the acutely ill patient illustrates the role of these safety strategies within the social organisation of clinical work. There is a need to broaden the focus of inquiry from detection and initiation of escalation (where the strategies are principally directed) towards team response behaviour and towards those medical response practices which to date have escaped scrutiny and monitoring.
