Obese people suffer from postural deficits and are more subject to falls than their lean counterpart. To improve prevention and post-fall rehabilitation programs, it seems important to better understand the posturo-kinetic disorders in daily life situations by determining the contribution of some key factors, mainly morphological characteristics and physical activity level, in the apparition of these disorders. Twelve severe android obese and eight healthy non obese adults performed a reaching task mobilizing the whole body. To further determine the origin of the postural and motor behavior differences, non obese individuals also performed an experimental session with additional constraints which simulated some of the obese morphological characteristics. Impact of the sedentary lifestyle was also studied by dissociation of the obese in two subgroups: physically « active » and physically « inactive ». Movement kinetics and kinematics were characterized with an optoelectronic system synchronized to a force platform. The mechanical equilibrium pattern was evaluated through the displacements of the Centre of Mass (CoM) and the centre of foot pressure within the Base of Support (BoS). Results showed that obesity decreased movement speed (?-23%, p<0.01), strongly increased CoM displacement (?+30%, p<0.05) and induced an important spatio-temporal desynchronization (?+40%, p<0.05) of the focal and postural components of the movement during the transition between the descending and ascending movements. The role of some morphological characteristics and of physical activity on obese patients' postural control disorder is discussed and set back in the more general context of overall factors contributing to postural deficits with obesity.

Infantile hemiplegia refers to brain injuries that occur before or at birth and lead to hemiplegia/ total paralysis of one side of the body, including the face, arm and leg. The main purpose of this article is to provide valuable information to pediatric dentists about the review and treatment alternatives for patients with infantile hemiplegia. This article reports the case of a 12-year-old girl with a hemiplegia of left side of the body suffering with tooth ache and gum inflammation. The treatment performed was rehabilitation with oral prophylaxis and extractions of root stumps followed by thorough preventive regimen with periodic check-ups. HubMed – rehab

Behçet’s disease (BD) is a systemic vasculitis characterized by inflammatory lesions of the urogenital mucosa, eyes, skin, central nervous system, and joints. Vein thrombosis constitutes the most frequent vascular manifestation of the disease, and may cause such ocular vascular thrombotic events as central retinal vein and central retinal artery thrombosis. Thrombosis is a serious problem, and often leads to irreversible vision loss. Previous studies have shown that genetic factors predispose individuals to BD. Several cytokine genes might play crucial roles in host susceptibility to BD and to thrombophilia. Various polymorphic regions of the interleukin-4 (IL-4) gene (-1098G and 590T) are associated with BD in the Turkish population. This study was conducted in Turkish patients with BD to determine the frequency of the IL-4 gene 70 bp variable number of tandem repeats (VNTR) variant, and its association with clinical findings.Genomic DNA obtained from 488 individuals (238 patients with Behçet’s disease and 250 healthy controls) was used in the study. Genomic DNA was isolated and genotyped using PCR assay for the IL-4 gene 70 bp VNTR polymorphism determined by using PCR with the specific primers.There was statistical significance between the groups regarding IL-4 genotype distribution (p<0.001, odds ratio: 2.55 [1.629-4.052], 95% confidence interval) and allele frequencies (p<0.0012.381[1.586-3.617], 95% confidence interval). When we examined IL-4 genotype frequencies according to the clinical characteristics, we observed a statistically significant association between the P2P2 genotype and deep venous thrombosis (p=0.01). Deep venous thrombosis was also associated with ocular involvement in our study group (p=0.014).Our findings suggest that the IL-4 gene 70 bp VNTR polymorphism is associated with susceptibility to development of BD. Deep venous thrombosis is also associated with ocular involvement in BD. The IL-4 gene could be a genetic biomarker in Behçet's disease in a Turkish study population. HubMed – rehab
