Article Synopsis
- This study explored how a mandibular advancement appliance (MAD) affects corticomotor excitability in patients with obstructive sleep apnea (OSA).
- Using a randomized, placebo-controlled design, 28 adults with mild or moderate OSA were tested to see how a 2-week use of MAD impacted muscle responses in the masseter and tongue.
- Results showed significant increases in both the masseter and tongue muscle activity after using the MAD, suggesting short-term use might enhance neuroplasticity in the brain pathways related to these muscles, which could improve understanding of OSA treatments.
Article Synopsis
- Atrial septal defect (ASD) is a common heart condition that often goes unnoticed in children, potentially leading to complications in adulthood if untreated.
- A study in Japan analyzed data from children with ASD who underwent procedures for closure, revealing that 37% were identified through school ECG screenings, especially those older than 6 years.
- The results indicate that ECG screenings are effective in detecting significant ASDs in asymptomatic students, highlighting their importance in early diagnosis and management.
Background: The evaluation of muscle pain and sensitivity by manual palpation is an important part of the clinical examination in patients with myalgia. However, the effects of clinical experience and visual feedback on palpation of the masticatory muscles with or without a palpometer are not known.
Objective: To estimate the effects of clinical experience and visual feedback on the accuracy of palpation in standardized settings.
Background: Studies addressing the training-induced neuroplasticity and interrelationships of the lip, masseter, and tongue motor representations in the human motor cortex using single syllable repetition are lacking.
Objective: This study investigated the impact of a repeated training in a novel PaTaKa diadochokinetic (DDK) orofacial motor task (OMT) on corticomotor control of the lips, masseter, and tongue muscles in young healthy participants.
Methods: A total of 22 young healthy volunteers performed 3 consecutive days of training in an OMT.
Objectives: This study aimed to determine if standardized palpations of the temporalis muscle evoke referred pain and/or sensations in individuals without TMD.
Materials And Methods: This was a randomized, single-blinded study. The mechanical sensitivity of the right temporalis muscle was assessed in 32 participants without TMD with nine different stimulations to 15 test sites using palpometers (different stimulus intensities (0.
Article Synopsis
- - This study examined how healthy individuals react to pain in the skin over the masseter muscle, focusing on two groups: those prone to masseter pain (MPP) and those who are not (non-MPP), distinguished by their responses to a specific palpation test.
- - Researchers conducted quantitative sensory testing (QST) to measure mechanical pain sensitivity and other pain thresholds, finding that the MPP group displayed higher pain sensitivity and lower pain thresholds compared to the non-MPP group.
- - After applying lidocaine (an anesthetic), both groups showed no significant differences in pain sensitivity, indicating that the differences in pain perception were mainly linked to physiological responses rather than other factors.
Importance: Chest radiography is a useful noninvasive modality to evaluate pulmonary blood flow status in patients with congenital heart disease. However, the predictive value of chest radiography is limited by the subjective and qualitive nature of the interpretation. Recently, deep learning has been used to analyze various images, but it has not been applied to analyzing chest radiographs in such patients.

We tested the hypothesis that CALs in patients long after Kawasaki disease are accompanied by atheroma-like features, as assessed by virtual histology-intravascular ultrasound, a new method to assess coronary plaque composition and morphology in vivo.
Methods And Results: Virtual histology-intravascular ultrasound was performed in 13 Japanese Kawasaki disease patients (median age, 18.
Background: Coronary sequelae that persist after Kawasaki disease (KD) have been associated with obstructive changes of the lesions and coronary vascular events in adolescents and young adults. However, little is known about the association between sequelae late after KD and inflammatory markers, which are potential mediators and markers for atherogenesis.
Methods And Results: Cross-sectional study was performed to test the hypothesis that coronary sequelae are associated with elevated levels of inflammatory markers in patients late after KD (mean time interval after the onset, 10 years, 10 months).
