RESUMEN
As one of the pregnancy complications， Placenta accreta is becoming increasingly common. Ultrasound is the primary technique for prenatal diagnosis of placenta accreta, whereas the features of the image are complex and the diagnostic criteria are not still uncover. This article reviewed the ultrasonographic features of placenta accrete on two-dimensional, color doppler and power doppler ultrasonography.
RESUMEN
<p><b>OBJECTIVE</b>To investigate the long-term clinical efficacy and adverse effects of botulinum toxin-A (BTX-A) injection in the treatment of gastrocnemius spasticity in children aged 9-36 months with cerebral palsy.</p><p><b>METHODS</b>Eighty children aged 9-36 months with cerebral palsy and gastrocnemius spasticity were selected and randomly divided into a BTX-A injection group and a conventional treatment group (n=40 each). The children in the BTX-A injection group received injections of BTX-A guided by color Doppler ultrasound and 4 courses of rehabilitation training after injection. Those in the conventional treatment group received 4 courses of the same rehabilitation training alone. Before treatment and at 1, 2, 3, and 6 months after treatment, the modified Tardieu scale (MTS) was applied to assess the degree of gastrocnemius spasticity, the values in the passive state measured by surface electromyography (sEMG) were applied to evaluate muscle tension, and the Gross Motor Function Measure (GMFM) was used to evaluate gross motor function.</p><p><b>RESULTS</b>Compared with the conventional treatment group, the BTX-A injection group had significantly greater reductions in MTS score and the values in the passive state measured by sEMG (P<0.05), as well as significantly greater increases in joint angles R1 and R2 in MTS and gross motor score in GMFM (P<0.05). No serious adverse reactions related to BTX-A injection were found.</p><p><b>CONCLUSIONS</b>BTX-A injection is effective and safe in the treatment of gastrocnemius spasticity in children aged 9-36 months with cerebral palsy.</p>
