Children and adolescents with Tourette's disorder in the USA versus Argentina: behavioral differences may reflect cultural factors.

To explore behavioral differences as possible cultural factors in presentation of psychiatric comorbidity in two clinically referred, consecutively ascertained samples of youth with Tourette's disorder (TD) from New York and Buenos Aires. Subjects were evaluated between 2002 and 2010 at the Tics and Tourette's Clinical and Research Program at the New York University Child Study Center in New York and the Interdisciplinary Center for Tourette's, Obsessive Compulsive Disorder (OCD) and Associated Disorders (CITTTA)/Institute of Cognitive Psychology (INECO) in Buenos Aires. Demographic, diagnostic, tic severity (Yale Global Tic Severity Scale; YGTSS), clinical (Child Behavior Check List-Parent version; CBCL), and global functioning (Global Assessment of Functioning; GAF) data were compared using descriptive statistics. The sample included 111 subjects ages 6-17 years, who met DSM-IV-TR diagnostic criteria for TD. Findings revealed that the BA sample (n = 35) was significantly older at initial evaluation at the tic specialty clinic, and had higher frequency of oppositional defiant disorder (ODD), mood and non-OCD anxiety disorders than the NY sample (n = 76). There were no differences in gender distribution, age at tic onset or TD diagnosis, tic severity, proportion with current diagnoses of OCD/OC behavior or attention deficit hyperactivity disorder (ADHD), CBCL internalizing, externalizing, or total problems scores, YGTSS scores, or GAF scores. The observed similarities in demographic features, clinical presentation, rates of ADHD and OCD/OCB, and global impairment may reflect similar phenomenology and illness-related characteristics of TD in these referred youth. Differences in age at initial specialty clinic evaluation and rates of ODD, mood and non-OCD anxiety disorders may need further exploration before they may be considered to reflect cultural factors. Because of these limitations (e.g. small sample size), these results can be regarded only as preliminary.

Testing tic suppression: comparing the effects of dexmethylphenidate to no medication in children and adolescents with attention-deficit/hyperactivity disorder and Tourette's disorder.

OBJECTIVE: The aim of this study was to conduct a pilot study testing whether single-dose, immediate-release dexmethylphenidate (dMPH) can facilitate tic suppression in children and adolescents with attention-deficit/hyperactivity disorder (ADHD) and Tourette's disorder (TD) or chronic tic disorders. The primary hypothesis is that dMPH will improve behaviorally reinforced tic suppression in a standard tic suppression paradigm (TSP). METHODS: Ten children with ADHD and TD were given dMPH on one visit and no medication on another, using a random crossover design. On both days, following a baseline period, subjects were reinforced for suppressing tics using a standard TSP. RESULTS: Thirteen subjects were enrolled; 10 subjects (mean age 12.7 +/- 2.6; 90% male) completed all study procedures. Relative to the no-medication condition, tics were reduced when children were given a single dose of dMPH. Behavioral reinforcement of tic suppression resulted in lower rates of tics compared to baseline, but dMPH did not enhance this suppression. CONCLUSION: Preliminary results indicate replication of prior studies of behavioral tic suppression in youths with TD and without ADHD. In addition, our findings indicate tic reduction (and not tic exacerbation) with acute dMPH challenge in children and adolescents with ADHD and TD.

Aripiprazole in children and adolescents with Tourette's disorder: an open-label safety and tolerability study.

OBJECTIVE: The aim of this study was to conduct a prospective safety and tolerability study of aripiprazole for the treatment of tics in children and adolescents with Tourette's disorder (TD). METHOD: Eleven subjects (10 males) with TD (age 9-19 years, mean 13.36, standard deviation [SD] 3.33) who did not respond or were unable to tolerate previous tic medication were treated with aripiprazole in an open-label, flexible-dosing study over 10 weeks. Tic severity was rated using the Yale Global Tic Severity Scale (YGTSS) and the Clinical Global Impressions Scale for tics (CGI-Tics) at baseline and at follow-up. RESULTS: The mean (+/-SD) daily dose for aripiprazole was 4.5 +/- 3.0 mg. Mean (+/-SD) YGTSS Global Severity scores reduced from 61.82 +/- 13.49 at baseline to 33.73 +/- 15.18 at end point; mean YGTSS total tic scores reduced from 28.18 +/- 7.74 at baseline to 16.73 +/- 7.54 at end point. Mean (+/-SD) CGI-Tic severity scores reduced from 4.45 +/- 0.52 (moderate-marked) at baseline to 3.18 +/- 0.60 (mild) at end point. On the CGI-Tic improvement scale, 10 (91%) subjects achieved 1 ("very much improved") or 2 ("much improved") at end point. Most common adverse effects included appetite increase and weight gain in 5 subjects, mild extrapyramidal effects in 7 subjects, and headaches and tiredness/fatigue in 7 subjects; 1 subject experienced akathisia and muscle cramps. CONCLUSION: Aripiprazole appears to be a safe and tolerable treatment in children and adolescents with TD that appears to reduce tics; it should be further investigated as a treatment option in controlled trials.

The prevalence and risk factors for percutaneous injuries in registered nurses in the home health care sector.

BACKGROUND: Patients continue to enter home health care (HHC) "sicker and quicker," often with complex health problems that require extensive intervention. This higher level of acuity may increase the risk of percutaneous injury (PI), yet information on the risk and risk factors for PI and other types of exposures in this setting is exceptionally sparse. To address this gap, a large cross-sectional study of self-reported exposures in HHC registered nurses (RNs) was conducted. METHODS: A convenience sample of HHC RNs (N=738) completed a survey addressing 5 major constructs: (1) worker-centered characteristics, (2) patient-related characteristics, (3) household characteristics, (4) organizational factors, and (5) prevalence of PIs and other blood and body fluid exposures. Analyses were directed at determining significant risk factors for exposure. RESULTS: Fourteen percent of RNs reported one or more PIs in the past 3 years (7.6 per 100 person-years). Nearly half (45.8%) of all PIs were not formally reported. PIs were significantly correlated with a number of factors, including lack of compliance with Standard Precautions (odds ratio [OR], 1.72; P=.019; 95% confidence interval [CI]: 1.09-2.71); recapping of needles (OR, 1.78; P=.016; 95% CI: 1.11-2.86); exposure to household stressors (OR, 1.99; P=.005; 95% CI: 1.22-3.25); exposure to violence (OR, 3.47; P=.001; 95% CI: 1.67-7.20); mandatory overtime (OR, 2.44; P=.006; 95% CI: 1.27-4.67); and safety climate (OR, 1.88; P=.004; 95% CI: 1.21-2.91) among others. CONCLUSION: The prevalence of PI was substantial. Underreporting rates and risk factors for exposure were similar to those identified in other RN work populations, although factors uniquely associated with home care were also identified. Risk mitigation strategies tailored to home care are needed to reduce risk of exposure in this setting.

Safety factors predictive of job satisfaction and job retention among home healthcare aides.

OBJECTIVES: Although many of the well known work characteristics associated with job satisfaction in home health care have been documented, a unique aspect of the home health care aides' (HHA) work environment that might also affect job satisfaction is the fact that their workplace is a household. To obtain a better understanding of the potential impact of the risks/exposures/hazards within the household environment on job satisfaction and job retention in home care, we recently conducted a risk assessment study. METHODS: Survey data from a convenience sample of 823 New York City HHAs were obtained and analyzed. RESULTS: Household/job-related risks, environmental exposures, transportation issues, threats/verbal and physical abuse, and potential for violence were significantly correlated with HHA job satisfaction and job retention. CONCLUSIONS: Addressing the modifiable risk factors in the home health care household may improve job satisfaction and reduce job turnover in this work population.
