Ganglion cyst arising from the infrapatellar fat pad in a child

A ganglion cyst is a cystic lesion containing myxoid matrix and lined by a pseudomembrane. A ganglion cyst arising from the infrapatellar fat pad is very rare, with only a few reports appearing in the literature, and the present case is the first report of this lesion in a child. A 10-year-old boy presented with right knee pain that showed no improvement despite resting from sports activity for 1 month. Magnetic resonance imaging revealed a multilobular mass between the infrapatellar fat pad and anterior cruciate ligament. Arthroscopic excision of the mass was performed. The mass was noted to arise from the infrapatellar fat pad and was filled with myxoid matrix. The histological diagnosis was a ganglion cyst. In active pediatric patients with pain or limited range of motion in the knee, physicians should consider the possibility of a ganglion cyst from the infrapatellar fat pad, despite its rarity

Robot-directed speech detection using multimodal semantic confidence based on speech, image, and motion

ABSTRACT In this paper, we propose a novel method to detect robotdirected (RD) speech that adopts the Multimodal Semantic Confidence (MSC) measure. The MSC measure is used to decide whether the speech can be interpreted as a feasible action under the current physical situation in an object manipulation task. This measure is calculated by integrating speech, image, and motion confidence measures with weightings that are optimized by logistic regression. Experimental results show that, compared with a baseline method that uses speech confidence only, MSC achieved an absolute increase of 5% for clean speech and 12% for noisy speech in terms of average maximum F-measure
