Article Abstract
Background: Improving chewing function of older adults increases the health-related quality of life. Few studies indicated the correlation between tongue, lip strength on masticatory performance in older people. The study aimed to investigate the association between lip, tongue strength on chewing pattern in aging population.
Methods: The older adults had independent daily intake without assistance were enrolled. They had intact dentition and no periodontitis. To estimate the number of chewing strokes and chewing time by consuming a cornstarch cookie were used to represent chewing pattern. Lip and tongue pressure were evaluated with an Iowa Oral Performance Instrument. Linear regression analysis was used to analyze the lip and tongue pressure associated with the chewing time and strokes. Spearman's correlation analysis was utilized to evaluate the associations among chewing time and chewing strokes or lip and tongue pressure.
Results: 35 women and 35 men with an average age of 73.2 years were investigated. Tongue pressure was significantly related to the chewing time and the number of chewing strokes (p = 0.01 and 0.03). There was a close association between chewing time and the number of chewing strokes (p < 0.0001). The correlation between lip and tongue pressure was significant (p < 0.0001).
Conclusion: The tongue strength significantly related to chewing ability in aging population. Increasing the tongue strength greatly reduced the number of chewing strokes and chewing time. Good masticatory ability could increase the motor function of tongue; raising the tongue strength might be able to improve mastication in older adults.

Effect of Localized Muscle Vibration on Oral and Swallowing Pressure in Patients with Dysphagia Following Stroke.
Dysphagia

Department of Occupational Therapy, CNC Purun Hospital, Cheongju, Chungcheongbuk-do, Republic of Korea.
This study examined the effects of vibratory stimulation on swallowing-related muscle strength in patients with dysphagia due to stroke, using three types of stimulators and a systematic exercise program. This study was conducted in two stages. In Experiment 1, we examined the effects of three types of vibratory stimulation on the pressure of the tongue and lips (N = 23).

Prior findings indicate that individuals who stutter do not show the typical modulation of auditory processing that is observed during speech movement planning in nonstuttering speakers. We now ask whether this lack of planning-related sensory modulation in stuttering adults is specific to the auditory domain. In this first study (15 stuttering and 15 nonstuttering participants), we implemented the prior stimulation timeline in a paradigm with orofacial skin stretch stimuli.

Background: Culler-Jones syndrome (CJS) is an autosomal dominant disorder characterized by hypopituitarism, postaxial polydactyly, and craniofacial anomalies, associated with pathogenic GLI2 variants. Genotype-phenotype correlations suggest missense variants may present with isolated pituitary phenotypes.
Methods: We evaluated an 8-year-old boy referred for short stature, failure to thrive, and neurodevelopmental concerns.

Department of Pediatric Plastic Surgery, Emma Children's Hospital, Amsterdam University Medical Center, Amsterdam, The Netherlands.
Objectives: To evaluate the effect of surgical timing of palatal closure on overall masticatory function in infants with cleft lip and/or palate (CL/P).
Materials And Methods: In this randomized controlled trial, 60 children with cleft lip and/or palate (CL/P) were assessed at the Wilhelmina Children's Hospital, University Medical Center Utrecht, the Netherlands. Participants were randomly assigned to early closure (Group A: 6-8 months) or late closure (Group B: 10-12 months).
"Airway-First, Heart-Early" Strategy: Managing Neonatal Dextro-Transposition of the Great Arteries in Pierre Robin Sequence.

Department of Pediatrics, Government Medical College, Srinagar, Srinagar, IND.
The concurrent presentation of Pierre-Robin sequence (PRS) and dextro-transposition of the great arteries (d-TGA) is extremely rare and presents distinct management challenges. We describe a term male neonate with the classic PRS triad (severe micrognathia, glossoptosis, and a U-shaped cleft palate) who developed profound cyanosis unresponsive to supplemental oxygen. Echocardiography demonstrated d-TGA with an intact ventricular septum, a restrictive patent foramen ovale, and a patent ductus arteriosus.
