Paediatric tic-like presentations during the COVID-19 pandemic.

BACKGROUND AND AIM: Clinical centres have seen an increase in tic-like movements during the COVID-19 pandemic. A series of children and adolescents are described. METHODS: A retrospective chart review of 34 consecutive paediatric patients presenting with sudden onset tic-like movements, seen over 6 months. RESULTS: 94% of patients were female, with an average age of sudden onset or increase of tic-like movements of 13.7 years. 44% had a previous diagnosis of tics, and 47% initially presented to an emergency department. Comorbid psychiatric and neurodevelopmental disorders were reported in 91% with 68% reporting anxiety. CONCLUSION: We highlight a dramatic presentation of sudden onset functional tic-like movements in predominantly female adolescents to help inform identification and management. There is need to research the neurobiological underpinnings and environmental exacerbating factors leading to these presentations and to explore effective therapeutic strategies.

Increased Risk of Tics in Children Infected with Enterovirus: A Nationwide Population-Based Study.

OBJECTIVE: Both tics and enterovirus (EV) infections are common in children. The association between EV infections and tics has been seldom evaluated. The aim of this study was to evaluate the risk of diagnosed tics after EV infections in children. METHODS: A nationwide retrospective cohort study was conducted to determine the risk of tics after EV infections by analyzing data from the National Health Insurance Research Database in Taiwan. Children aged < 18 years with EV infection during 2000 to 2007 were enrolled. For comparison, non-EV-infected children were randomly selected and matched with EV-infected children at a 1:1 ratio according to sex, age, urbanization level, parental occupation, and the year of EV infection. All patients were followed up until the diagnosis of tics, death, loss to follow-up, withdrawal from the insurance system, or December 31, 2008. RESULTS: A total of 282,321 EV-infected and 282,317 non-EV-infected children were included in this study. The mean age was 2.39 years in both cohorts. The overall incidences of tics were 9.12 and 6.21 per 10,000 person-years in the EV-infected and non-EV-infected cohorts, respectively. Children with EV infection were significantly associated with an increased risk of tics compared with those without EV infection (adjusted hazard ratio, 1.38; 95% confidence interval, 1.27-1.5). Multivariable analyses showed that boys, children living in urbanized areas, children whose parents had white-collar jobs, and children with allergic rhinitis or bronchial asthma exhibited a significantly increased risk of tics. CONCLUSION: This study revealed an increased risk of tics after EV infection in children.

[Epidemiology of TBE]. / Jetzt stechen sie wieder! In immer mehr Regionen sind Zecken FSME-Träger.

In the period between 1974 and 2003, the incidence of TBE increased appreciably in most European countries. Numerous factors, including climatic changes, biological (ecological) and non-biological factors, have an influence on the epidemiology of TBE. In addition, a greater awareness and better understanding (of the problem), improvements in diagnosis, an increase in travel, political and associated major social changes have had an impact on epidemiological data banks. We shall succeed in turning back the rising tide only by achieving further progress in the field of risk analysis, and redoubling our efforts in the area of active immunisation.
