[Numb chin syndrome].

Background: Numb chin syndrome describes sensory neuropathy characterised by numbness in the distribution of the terminal branch of the mandibular division of the trigeminal nerve. This symptom may be overlooked by patients and clinicians due to its mild nature; however, it could represent a serious underlying pathology such as inflammatory conditions or malignancy.

Case Presentation: A man in his seventies presented with isolated numbness on the right side of the chin, and no other neurological or constitutional symptoms.

[A woman in her fifties with left bundle branch block and recurrent arrhythmias].

Background: Sarcoidosis is a multi-system inflammatory disorder resulting in the formation of non-caseating granulomas in various parts of the body. Cardiac involvement is associated with worse prognosis, probably due to the destructive effects the granulomas can have on the electrical conduction system. The diagnosis of cardiac sarcoidosis can be challenging due to the limited accuracy of various clinical criteria.

Handgrip force steadiness in young and older adults: a reproducibility study.

Background: Force steadiness is a quantitative measure of the ability to control muscle tonus. It is an independent predictor of functional performance and has shown to correlate well with different degrees of motor impairment following stroke. Despite being clinically relevant, few studies have assessed the validity of measuring force steadiness.

Reference data on reaction time and aging using the Nintendo Wii Balance Board: A cross-sectional study of 354 subjects from 20 to 99 years of age.

Background: Falls among older adults is one of the major public health challenges facing the rapidly changing demography. The valid assessment of reaction time (RT) and other well-documented risk factors for falls are mainly restricted to specialized clinics due to the equipment needed. The Nintendo Wii Balance Board has the potential to be a multi-modal test and intervention instrument for these risk factors, however, reference data are lacking.
