Associations of Masticatory Muscles Asymmetry and Oral Health with Postural Control and Leg Injuries of Elite Junior Soccer Players.

The influence of asymmetry between masticatory muscles on postural control is still under debate and only few studies examined the impact of oral health on injury risk. The present study investigated the relationships between masticatory muscles asymmetry, oral health, postural control and the prevalence of (non-contact or traumatic) leg injuries in a sample of 144 male elite junior soccer players. sEMG of the masseter and temporal muscles was performed during maximum teeth clenching, postural control was tested by measuring sway velocity during the unipedal stance with eyes closed, while oral health and the number of leg injuries were assessed using a questionnaire.

Are oral health and fixed orthodontic appliances associated with sports injuries and postural stability in elite junior male soccer players?

Background: Dental caries and periodontitis are associated with elevated levels of pro-inflammatory cytokines which may trigger muscle fatigue during exercise, a strong risk factor for sports injuries. Fixed orthodontic appliances (FOA) may cause poor oral health and may disturb proprioceptive inputs of the stomatognathic system. This study aims to explore associations of poor oral health and of use of a FOA with injury frequency and postural stability.

Extremely elevated cerebrospinal fluid protein levels in a child with neurologic symptoms: beware of haemophagocytic lymphohistiocytosis.

Neurologic symptoms can be the initial manifestation of haemophagocytic lymphohistiocytosis (HLH). In this case study, we present a 3-year old boy with a clinical picture of encephalitis, a cerebrospinal fluid (CSF) protein level up to 1165 mg/dl and diffuse cerebral MRI abnormalities. The diagnosis of HLH was established only 6 weeks after initial presentation.
