Alessitimia e disturbi da tic: uno studio su un campione di bambini e di genitori
I disturbi da tic sono disturbi del neurosviluppo ad esordio in età evolutiva caratterizzati dalla presenza di tic motori o fonici, o entrambi. I pazienti con disturbi da tic riferiscono comunemente sensazioni premonitrici dei tic. L’alessitimia è un tratti psicologico caratterizzato da una difficoltà nell’identificazione e nell’espressione delle emozioni e da un pensiero orientato all’esterno. Lo scopo dello studio è di esplorare l’alessitimia in bambini con disturbi da tic e nelle loro madri. I punteggi globali di alessitimia dei bambini con distrubi da tic e delle loro madri non differiscono da quelli dei bambini del gruppo di controllo e delle loro madri. Tuttavia, sia i bambini che le loro madri mostrano alcune caratteristiche alessitimiche (pensiero orientato all’esterno). Le madri dei bambini affetti riferiscono uno stress parentale significativamente maggiore di quello riportato dalle madri del gruppo di controllo. L’alessitimia non è predittiva della gravità dei tic, tuttavia è predittiva della gravità delle sensazioni premonitrici dei tic

A randomized controlled trial comparing behavioral, educational, and pharmacological treatments in youths with chronic tic disorder or Tourette syndrome
Context: The existing literature on the treatment of pediatric chronic tic disorder (CTD) and Tourette syndrome (TS) indicates that both behavioral therapy (BT) and pharmacotherapy (PT) are effective for reducing symptoms. Objective: To evaluate the efficacy of BT compared to psychoeducation (PE) or PT for reducing tics and co-occurring symptoms and for improving quality of life (QoL) in a sample of youths with CTD and TS. Design: A 10 weeks, 2 sites (Catania, Rome) randomized controlled trial. Participants were randomized to receive one of the following treatments: BT, PE, or PT. Participants: 110 outpatients aged between 8 and 17 years affected by CTD or TS. Results: Patients in the BT and PT groups showed a significant reduction in the severity of tic symptoms, while the PE group did not show any improvement. PT was more effective for reducing obsessive compulsive symptoms than BT, while PE group did not show any improvement. Both BT and PT groups showed an improvement in most QoL domains, whereas no differences were found in the PE group. Conclusions: BT is as effective as pharmacological therapy in the treatment of tic disorders in children and adolescents, thus offering an alternative to medications for CTD and TS
Workplace violence in different settings and among various health professionals in an Italian general hospital: a cross-sectional study
Background: Workplace violence (WPV) against health professionals is a global problem with
an increasing incidence. The aims of this study were as follows: 1) to examine the frequency
and characteristics of WPV in different settings and professionals of a general hospital and 2)
to identify the clinical and organizational factors related to this phenomenon.
Methods: The study was cross-sectional. In a 1-month period, we administered the “Violent
Incident Form” to 745 professionals (physicians, head nurses, nurses, nursing assistants), who
worked in 15 wards of a general hospital in northern Italy.
Results: With a response rate of 56%, 45% of professionals reported WPV. The most frequently
assaulted were nurses (67%), followed by nursing assistants (18%) and physicians
(12%). The first two categories were correlated, in a statistically significant way, with the risk of
WPV (P=0.005, P=0.004, multiple logistic regression). The violent incidents more frequently
occurred in psychiatry department (86%), emergency department (71%), and in geriatric wards
(57%). The assailants more frequently were males whereas assaulted professionals more often
were females. Men committed physical violence more frequently than women, in a statistically
significant way (P=0.034, chi-squared test). Verbal violence (51%) was often committed by
people in a lucid and normal state of consciousness; physical violence (49%) was most often
perpetrated by assailants affected by dementia, mental retardation, drug and substance abuse,
or other psychiatric disorders. The variables positively related to WPV were “calling for help
during the attack” and “physical injuries suffered in violent attack” (P=0.02, P=0.03, multiple
logistic regression).
Conclusion: This study suggests that violence is a significant phenomenon and that all health
workers, especially nurses, are at risk of suffering aggressive assaults. WPV presented specific
characteristics related to the health care settings, where the aggression occurred. Prevention
programs tailored to the different care needs are necessary to promote professional awareness
for violence risk
Health-related quality of life in patients with Gilles de la Tourette syndrome at the transition between adolescence and adulthood
Gilles de la Tourette syndrome (GTS) is a neurodevelopmental
condition characterised by tics and comorbid
behavioural problems, affecting predominantly
male patients. Tic severity typically fluctuates over time,
with a consistent pattern showing improvement after adolescence
in a considerable proportion of patients. Both tics
and behavioural co-morbidities have been shown to have
the potential to affect patients’ health-related quality of life
(HR-QoL) in children and adults with persisting symptoms.
In this study, we present the results of the first investigation
of HR-QoL in patients with Gilles de la Tourette syndrome
at the transition between adolescence and adulthood using
a disease-specific HR-QoL measure, the Gilles de la
Tourette Syndrome-Quality of Life-Children and Adolescents
scale. Our results showed that patients with GTS and
more severe co-morbid anxiety symptoms reported lower
HR-QoL across all domains, highlighting the impact of
anxiety on patient’s well-being at a critical stage of
development. Routine screening for anxiety symptoms is
recommended in all patients with GTS seen at transition
clinics from paediatric to adult care, to implement effective
behavioural and pharmacological interventions as
appropriate
Clinical precursors of tics: an EMTICS study
Background: Children with Tourette syndrome (TS) often have comorbid disorders, particularly attention-deficit/ hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD). While subtle premorbid symptoms have been described in various psychiatric disorders, the presence of clinical precursors that may exist before the onset of tics is unknown. This longitudinal study aimed to find clinical precursors of tics by assessing a range of clinical characteristics prior to tic onset in comparison with children without onset of tics. Methods: A sample of 187 3- to 10-year-old first-degree unaffected relatives of children with TS were followed up to 7 years in the European Multicentre Tics in Children Study (EMTICS). We investigated whether clinical characteristics assessed at baseline predicted tic onset, comparing 126 children without tic onset to 61 children who developed tics. We used the least absolute shrinkage and selection operator (LASSO) method, a penalised logistic regression approach. We also explored sex differences and repeated our analyses in an age- and sex-matched subsample. Results: Children with tic onset were more frequently male (b = 0.36), had higher baseline severity of conduct problems (b = 0.23), autism spectrum disorder symptoms (ASD; b = 0.08), compulsions (b = 0.02) and emotional problems (b = 0.03) compared to children without tic onset. Conduct and ASD problems were male-specific predictors, whereas severity of compulsions and oppositional (b = 0.39) and emotional problems were female-specific predictors. Conclusion: This study supports the presence of clinical precursors prior to tic onset and highlights the need of sex-specific monitoring of children at risk of developing tics. This may aid in the earlier detection of tics, particularly in females. We moreover found that tics most often persisted one year after tic onset, in contrast to the common belief that tics are mostly transient
Hair cortisol-a stress marker in children and adolescents with chronic tic disorders? A large European cross-sectional study
Background
There is clear evidence that tic disorders (TDs) are associated with psychosocial stress as well as emotional and behavioral problems. Studies have shown that individuals with TDs have higher acute physiological stress responses to external, single stressors (as reflected by saliva cortisol). The aim of the present study was to examine a physiological marker of longer-term stress (as reflected by hair cortisol concentration) in children and adolescents with TDs and unaffected siblings of individuals with TDs.
Methods
Two samples of a European cohort were included in this study. In the COURSE sample, 412 children and adolescents aged 3–16 years with a chronic TD including Tourette syndrome according to DSM IV-TR criteria were included. The ONSET sample included 131 3–10 years old siblings of individuals with TDs, who themselves had no tics. Differences in hair cortisol concentration (HCC) between the two samples were examined. Within the COURSE sample, relations of HCC with tic severity and perceived psychosocial stress as well as potential effects and interaction effects of comorbid emotional and behavioral problems and psychotropic medication on HCC were investigated.
Results
There were no differences in HCC between the two samples. In participants with TDs, there were no associations between HCC and tic severity or perceived psychosocial stress. No main effects of sex, psychotropic medication status and comorbid emotional and behavioral problems on HCC were found in participants with TDs.
Conclusion
A link between HCC and TDs is not supported by the present result
Tic disorders in children and adolescents: does the clinical presentation differ in males and females? A report by the EMTICS group
Tic disorders have a strong male predominance, with a male-to-female ratio of 4:1 in Tourette syndrome (TS) and 2:1 in persistent tic disorders. In other neurodevelopmental conditions, such as autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), the disparity in sex distribution has been partially related to differences in symptom presentation between males and females. In tic disorders, however, little research has been conducted on this topic, probably due to the limited access to large samples with a significant proportion of females. The aim of this study was to describe sex differences in the clinical presentation of tic disorders in children and adolescents in one of the largest pediatric samples with TS/persistent tic disorders (n = 709, 23.3% females) recruited as part of the European Multicenter Tics in Children Study (EMTICS). Validated measures assessed the severity of tics and comorbid psychiatric symptoms. Using mixed-effect models, we found that sex had a significant influence on the severity of tics, ADHD symptoms, ASD symptoms, and emotional problems. Males had more severe symptoms than females, except for emotional problems. We also observed a statistically significant interaction between sex and age on the severity of tics and compulsions, with females showing higher symptom severity with increasing age than males. These findings indicate that the clinical presentation of TS/persistent tic disorders varies with sex. Males seem to exhibit a more noticeable pattern of clinical symptoms at a younger age that may contribute to their earlier detection in comparison to females
Yale Global Tic Severity Scale (YGTSS): Psychometric Quality of the Gold Standard for Tic Assessment Based on the Large-Scale EMTICS Study
The Yale Global Tic Severity Scale (YGTSS) is a clinician-rated instrument considered as the gold standard for assessing tics in patients with Tourette's Syndrome and other tic disorders. Previous psychometric investigations of the YGTSS exhibit different limitations such as small sample sizes and insufficient methods. To overcome these shortcomings, we used a subsample of the large-scale “European Multicentre Tics in Children Study” (EMTICS) including 706 children and adolescents with a chronic tic disorder and investigated convergent, discriminant and factorial validity, as well as internal consistency of the YGTSS. Our results confirm acceptable convergent and good to very good discriminant validity, respectively, indicated by a sufficiently high correlation of the YGTSS total tic score with the Clinical Global Impression Scale for tics (rs = 0.65) and only low to medium correlations with clinical severity ratings of attention deficit/hyperactivity symptoms (rs = 0.24), obsessive–compulsive symptoms (rs = 27) as well as internalizing symptoms (rs = 0.27). Internal consistency was found to be acceptable (Ω = 0.58 for YGTSS total tic score). A confirmatory factor analysis supports the concept of the two factors “motor tics” and “phonic tics,” but still demonstrated just a marginal model fit (root mean square error of approximation = 0.09 [0.08; 0.10], comparative fit index = 0.90, and Tucker Lewis index = 0.87). A subsequent analysis of local misspecifications revealed correlated measurement errors, suggesting opportunities for improvement regarding the item wording. In conclusion, our results indicate acceptable psychometric quality of the YGTSS. However, taking the wide use and importance of the YGTSS into account, our results suggest the need for further investigations and improvements of the YGTSS. In addition, our results show limitations of the global severity score as a sum score indicating that the separate use of the total tic score and the impairment rating is more beneficial
Association of Group A Streptococcus Exposure and Exacerbations of Chronic Tic Disorders
Objective: To examine prospectively the association between group A Streptococcus (GAS) pharyngeal exposures and exacerbations of tics in a large multicenter population of youth with chronic tic disorders (CTD) across Europe.
Methods: We followed up 715 children with CTD (age 10.7 ± 2.8 years, 76.8% boys), recruited by 16 specialist clinics from 9 countries, and followed up for 16 months on average. Tic, obsessive-compulsive symptom (OCS), and attention-deficit/hyperactivity disorder (ADHD) severity was assessed during 4-monthly study visits and telephone interviews. GAS exposures were analyzed using 4 possible combinations of measures based on pharyngeal swab and serologic testing. The associations between GAS exposures and tic exacerbations or changes of tic, OC, and ADHD symptom severity were measured, respectively, using multivariate logistic regression plus multiple failure time analyses and mixed effects linear regression.
Results: A total of 405 exacerbations occurred in 308 of 715 (43%) participants. The proportion of exacerbations temporally associated with GAS exposure ranged from 5.5% to 12.9%, depending on GAS exposure definition. We did not detect any significant association of any of the 4 GAS exposure definitions with tic exacerbations (odds ratios ranging between 1.006 and 1.235, all p values >0.3). GAS exposures were associated with longitudinal changes of hyperactivity-impulsivity symptom severity ranging from 17% to 21%, depending on GAS exposure definition.
Conclusions: This study does not support GAS exposures as contributing factors for tic exacerbations in children with CTD. Specific workup or active management of GAS infections is unlikely to help modify the course of tics in CTD and is therefore not recommended
