Babies are ideal subjects for investigation by sonography. They are small and easily examined with the use of high-frequency transducers. Their unique status in US imaging tends to get lost amid the array of other available modalities, such as MRI and CT imaging. Some of the questions posed in pediatric musculoskeletal imaging that are routinely directed to other imaging modalities can be solved quickly at a lower cost by sonography in neonates and infants without sedation or any known clinical risk. These small children not only have thinner soft tissues but they have long bones and midline spine structures whose ends are largely composed of cartilage, which provides an early opportunity to examine these regions by US. And we cannot overestimate the value of new parents being able to stay next to their baby during imaging in a warm, friendly and non-threatening environment.
The optimal strategy for follow-up of extremity soft tissue sarcoma patients after primary treatment with curative intent is not known. The 1592 members of the Society of Surgical Oncology (SSO) were sent a survey to determine their practices. Office visits and chest X-rays were the most frequently performed items for all years. Complete blood count and liver function tests were the most commonly ordered blood tests, but many respondents did not order any blood tests routinely. Imaging studies of the extremities were recommended for most patients during the first postoperative year. Postoperative surveillance strategies after sarcoma treatment vary appreciably among surgeons. Surgeon age, tumor size, tumor grade, and geographic location of the surgeon account for only a modest amount of the variation, suggesting that lack of evidence supporting any particular strategy is the factor responsible for most of the variation. Efforts to provide high-quality evidence on this topic are warranted.
Previous research has demonstrated that people's movements can become unintentionally coordinated during interpersonal interaction. The current study sought to uncover the degree to which visual and verbal (conversation) interaction constrains and organizes the rhythmic limb movements of coactors. Two experiments were conducted in which pairs of participants completed an interpersonal puzzle task while swinging handheld pendulums with instructions that minimized intentional coordination but facilitated either visual or verbal interaction. Cross-spectral analysis revealed a higher degree of coordination for conditions in which the pairs were visually coupled. In contrast, verbal interaction alone was not found to provide a sufficient medium for unintentional coordination to occur, nor did it enhance the unintentional coordination that emerged during visual interaction. The results raise questions concerning differences between visual and verbal informational linkages during interaction and how these differences may affect interpersonal movement production and its coordination.
