[Computerized oculomotor training in dyslexia: A randomized, crossover clinical trial in pediatric population]. / Rééducation oculomotrice informatisée dans la dyslexie : essai clinique randomisé en crossover en population pédiatrique.

OBJECTIVE: Several studies have reported abnormal oculomotor capacities leading to reading/writing difficulties among dyslexic children. However, no randomized clinical trial has been conducted to determine whether oculomotor training improves reading/writing skills of these children. The present study aims to evaluate the efficacy of computer-based oculomotor training among dyslexic children. METHOD: Crossover randomized trial with enrollment from January 12, 2015 to July 24, 2015, and follow-up to February 4, 2016. Eleven children (aged 7 to 12 years old) with dyslexia were included in a French psychiatric unit. The computer-based oculomotor training consisted of exercises focused on control of saccadic movements (reflexes and voluntary saccades), vergences and visual attention and memory. At baseline, 3 and 6 months, participants were assessed on reading and writing skills as well as phonological skills, visuo-attentional skills and verbal memory using the French batterie analytique du langage écrit (BALE). Saccadic and antisaccadic ocular movements (latencies and gains) were recorded using a specific device. Several Anova models were performed to test whether oculomotor training improves reading, writing and phonological, verbal memory and visuo-attentional skills. Our analyses were considered exploratory (alpha at 5%). RESULTS: No effect of oculomotor training was found on reading skills. However, oculomotor training was associated with a short-term effect (after 3 months of training) on several tests measuring phonological skills (syllabic suppression; P-value=0.022), visuo-attentional skills (search of anarchic verbal cues; P-value=0.035) and verbal memory (digit span backward; P-value=0.022) and with a long-term effect (3 months after the end of the 3 months of training) on a measure of writing skills (regular words; P-value=0.019). Finally, training was associated with an increase of saccadic latencies indicating an increase of visuo-attentional skills (P-value=0.026). CONCLUSIONS: Our results suggested that computer-based oculomotor training might be effective on writing skills and several cognitive skills among dyslexic children, but future clinical trials are needed to confirm our results.

[Clinical assessment of the risk of Human Immunodeficiency virus (HIV) infection in the population consulting an anonymous and free screening center]. / Evaluation clinique du risque d'infection par le virus de l'immunodéficience humaine (VIH) de la population consultant dans un centre de dépistage anonyme et gratuit (CDAG).

INTRODUCTION: The anonymous and free AIDS screening centers were developed in France in 1987 to incite the general population to undergo screening for HIV infection. The aim of this paper was to conduct a prospective study describing the principle characteristics and level of risk of those consulting a center in the Year 1999. POPULATION AND METHODS: A face to face physician-consultant questionnaire was proposed to all the consultants that Year. It included 20 questions regrouped in general characteristics of the subject, number of previous screenings, reason for screening, type of risk taken, date of last risk taken, and number of sexual partners during the past 12 Months and throughout their life without the use of a condom. RESULTS: Two thousand six hundred seventy-eight persons consulted (sex ratio=1) aged a mean of 25.8 Years. The men were older than the women (respectively 27 versus 24.6; p<0.05). The reason for screening was a decision made by the couple in 44.6 p. 100, an unprotected sexual relationship in 47.6 p. 100 another reason in 7.6 p. 100 and drug abuse in 0.2 p. 100 of cases. The sex mode declared was heterosexual in 94.5 p. 100 and homo or bisexual in 5.4 p. 100. The majority of those consulting (66.2 p. 100) had had between 0 and 2 partners during the past 12 Months; 66 p. 100 had had more than 10 during their life without using a condom. The assessment of the global risk by the physician was: very high in 1 p. 100, high in 2.5 p. 100, moderate in 13.3 p. 100, low in 70.7 p. 100 and nil in 12.5 p. cent. Five HIV infections were diagnosed, all in persons at high or very high risk. DISCUSSION: These results should stimulate the radical differentiation of the management of persons consulting according to the level of risk identified by the medical questionnaire.
