- Introduction: Impaired isometric muscle strength was previously reported in adults with Fontan circulation. However, it is unclear if this impairment is present in children and adolescents with Fontan circulation. We investigated isometric muscle strength of the lower limb in patients (6–18 years) with Fontan circulation in comparison with healthy controls.Method: In this cross-sectional study, 43 patients (6–18 years) with Fontan circulation and 43 age- and sex-matched controls were included. Isometric knee extension and plantar flexion muscle strength were assessed using dynamometry (Newton, N). Lean mass of the legs was assessed with dual-energy X-ray absorptiometry. Analyses were performed on group level (n = 43), and for subgroups that included children aged 6–12 years (n = 18) and adolescents aged 13–18 years (n = 25).Results: On group level, the patients with Fontan circulation had impaired isometric knee extension strength in comparison with the controls (p = 0.03). In subgroup analyses, impaired isometric knee extension strength was present in the adolescents (p = 0.009) but not in the children groups. For plantar flexion, there was no difference between patients and controls. There was no difference in lean mass between patients and controls (9.6 ± 4.3 kg vs. 10.8 ± 5.6 kg, p = 0.31). However, the lean mass was highly correlated to isometric knee extension strength (patients r = 0.89, controls r = 0.96, p < 0.001) and isometric plantar flexion strength (patients r = 0.7, controls r = 0.81, p < 0.001).Conclusion: The finding of impaired isometric knee extension muscle strength in adolescents (13–18 years) with Fontan circulation and no corresponding impairment in the children group (6–12 years) could imply that isometric muscle strength gets more impaired with age.

- Aims: To provide an update of knowledge regarding the clinical presentation and neurophysiologic aspects of orofacial pain of cardiac origin in the form of a literature review. Methods: The peer-reviewed databases Scopus/Embase, NCBI (PubMed), and Science Direct were searched up to December 2018. Results: Patients with myocardial infarction presenting without chest pain run a higher risk of death due to missed diagnosis and subsequently a significantly greater delay between the onset of symptoms and arrival at the hospital. During myocardial ischemia, orofacial pain is reported by 4 in 10 patients and described as oppressive and/or burning. Up to 4% of myocardial infarction patients experience pain solely in the orofacial structures, women more often than men. Orofacial pain during myocardial ischemia is associated with ischemia within the inferior wall of the heart, suggesting the involvement of the vagal system. Conclusion: The clinician’s awareness of the full spectrum of clinical characteristics of a myocardial infarction constitutes a key factor in accurate diagnosis. Health care professionals and the general public should be aware of the possibility of myocardial infarction presenting with orofacial pain, toothache, or ear/temporomandibular joint pain as the only symptom.
