The oral feeding disorder is one of the important indicators for the high risk group of neurodevelopment delay. The procedure of oral feeding requires the coordination of sucking, swallowing, and breathing activities, and it is the most complex sensorimotor process for newborn infants. Premature infants often uneasily complete the procedure of oral feeding. However, the evaluation of the oral feeding disorders and severity are usually dependent on the subjective clinical experience of the physician. Monitoring the sucking-swallowing-breathing activities directly is difficult for preterm infants. In this study, a wireless monitoring system for oral-feeding evaluation of full term and preterm infants was proposed to objectively and quantitatively evaluate the coordination of suck-swallow-respiration function during oral feeding. Moreover, the ratios of the swallowing and breathing event numbers to the sucking event number were defined to evaluate the coordination of suck-swallow-respiration function during oral feeding. Finally, the system performance was validated and the coordination of suck-swallow-respiration function for full term and preterm infants during oral feeding was also investigated.
Nail pathologies have a broad range of origin and may sometimes be complicated in presentation or clinical course, specifically when the pathology remains recalcitrant after treatment. In this case report we discuss a pathologic disorder that was initially misdiagnosed as a pyogenic granuloma surrounding an ingrown nail but was later found to be a benign neoplastic bone growth, Dupuytren exostosis, also known as a subungual exostosis. Operative treatment was deemed appropriate for the patient, and the exostosis was resected, leaving a soft-tissue void at the distal toe. The remaining void was filled with a perinatal graft, the use of which has been deemed effective anecdotally in both chronic and acute lower-extremity wounds but has not been widely discussed in the lower-extremity literature. This graft was placed to aid in wound healing over a potentially difficult wound bed. As amniotic, chorionic, and umbilical grafts become more prevalent in lower-extremity surgery, its antitumor effects should be further explored and published. This is the first case report, to our knowledge, of the successful use of a perinatal graft in the setting of a bone tumor, and it demonstrates that certain benign neoplasms can be treated with resection and placement of a perinatal graft while helping to prevent chronic wounds at surgical sites.
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.
