Editorial: Trials and tribulations in child psychology and psychiatry: what is needed for evidence‐based practice

If your child had leukaemia you would be distraught. Yet, there would also be hope. Most children with a diagnosis of leukaemia start their treatment as part of ongoing trials. The clinical teams looking after such children are motivated, knowledgeable and work in centres that specialise in the treatment of this lethal illness. The results speak for themselves. Not only have the trials helped oncologists learn more about which treatments work best. For years we have known that those who enter trials do better than those patients with similar characteristics who don't. We have recently also learnt that trials improve survival rates in those cancers population wide: the annual reduction between 1978–2005 in risk of death from childhood cancers ranged from 2.7% to 12.0%. This cancer trial culture is a splendid example of British health care delivery. What is happening in child psychiatry, though? If your child had, say, depression you would have every reason to be distraught too. The mortality rate is higher than in the general population and the burden of disease in the long run heavier than that of cardiovascular illness or cancer. Yet, your child would not have access to a trial. Instead, you would probably struggle to have your child's depression recognised in the first place. The care you would get would be determined by extreme regional variations and by what resources are available to local services and often the ideology or preferences of practitioners.     

Depression Screening in Adolescents in the United States: A National Study of Ambulatory Office-Based Practice

ObjectiveTo determine the frequency of depression screening during ambulatory, office-based visits for adolescents seen in general/family medicine or pediatric practices in the United States using nationally representative data; to determine the patient-, provider-, and visit-level factors associated with depression screening during ambulatory visits to inform recommendations to promote screening.MethodsThis cross-sectional study used the 2005–2010 National Ambulatory Medical Care and National Hospital Ambulatory Medical Care Surveys. Data were limited to ambulatory, office-based visits to general/family medicine or pediatrics clinics for adolescents aged 12 to 18 years who did not have a documented diagnosis of depression.ResultsDepression screening was rare (0.2%; 95% confidence interval [CI] 0.1–0.3), and it was 80% less likely to occur during visits for Hispanic compared to non-Hispanic white adolescents (adjusted odds ratio [aOR] 0.2, 95% CI 0.1–0.7). Depression screening was 9.1 times more likely in the Northeast compared to the West (aOR 9.1, 95% CI 2.2–38.1) if there were no visits within past 12 months compared to 6 or more visits (aOR 6.1; 95% CI 1.8–20.4), and if stress management (aOR 24.2, 95% CI 11.8–49.5) or other mental health counseling (aOR 5.2, 95% CI 1.2–23.6) were provided.ConclusionsDepression screening for adolescents is rare and is associated with racial/ethnic and regional disparities. The integration of behavioral and mental health services within the patient-centered medical home might assist providers in identifying and treating depression and in addressing such disparities.     

Snuff use and smoking among senior high school students: effects of a snuff sales ban

OBJECTIVES: The popularity of snuff especially among adolescents is rising. The association between long-term snuff use and oral cancer discovered in epidemiological studies has prompted a variety of preventive measures to be taken to reduce snuff use and prevent adoption of the habit. In this study, the effect of a recent (I March, 1995) snuff sales ban introduced in Finland was investigated. Further, the rates of smoking, snuff use, alcohol use and drug experimenting were investigated before the introduction of the ban to characterize the study population.
DESIGN AND SUBJECTS: Two questionnaire studies were carried out. The first was carried out 3 months prior to the ban in 1994 and the second 9 months after the ban in 1995 in a senior high school population in southwestern Finland. The participants were 793 students (aged 15–22 years) in the first survey and 545 students (aged 16–23) in the second. Associations between variables were analyzed using cross-tabulation and stepwise logistic regression. The effects of the ban were determined on the basis of direct questions in the second questionnaire relating to the snuff sales ban.
RESULTS: Snuff was used by 9% of the students participating in the first study. The results of the second questionnaire indicate that the implementation of the snuff sales ban reduced the rate of snuff use by 1% in the study population. The majority of the snuff users (76%) reported that they had maintained their snuff habit. Of those reporting that they were snuff users before implementation of the snuff sales ban, 12% had switched to smoking and 5% to drugs.
CONCLUSIONS: The results of the present study suggest that the snuff sales ban in this population with a high rate of snuff use had little effect on snuff use rates and may have some short-term negative consequences as some snuff users switch to other substitutes, such as smoking, with known adverse health effects.     

Temporomandibular clinical exploration in Italian adolescents

Objective: This study investigated the prevalence of the signs and symptoms of temporomandibular disorders (TMD) among Italian adolescents.

Methods: The data were recorded from 567 subjects (246 males and 321 females; age range 11–19 years), grouped according to age and molar class relationship.

Results: Forty-four point one percent of subjects showed at least one sign or symptom of TMD, which were significantly more frequent in the 16–19 year-old group (52.9%) in respect to the 11–15 year-old group (39.8%) (χ ² = 8.78; p = 0.003). Signs and/or symptoms were about 1.6 times more frequent in subjects with Class II/1 malocclusion (χ ² = 13.3, p = 0.0003), mostly for TMJ sounds (χ ² = 1.444; p = 0.036). Myalgia was more frequent in females than in males (χ ² = 3.882; p = 0.049).

Conclusion: TMD signs and/or symptoms among Italian adolescents seem diffused (44.1%). Therefore, all adolescents should be screened thorough medical history and clinical examination.     

Relationship between functional disc position and mandibular displacement in adolescent females: posteroanterior cephalograms and magnetic resonance imaging retrospective study

The purpose of this study was to investigate the relationship between the disc positions of temporomandibular joints (TMJ), the vertical and lateral mandibular displacement (VMD and LMD, respectively) and age in female adolescents with signs and symptoms of the temporomandibular disorders (TMD). The VMD and LMD were assessed, using posteroanterior (PA) cephalograms. The disc positions were assessed by magnetic resonance imaging (MRI) and categorized as follows: normal disc position, functional disc displacement and functional disc dislocation. Excluding patients with osteoarthritis, the total number of subjects was 54 female adolescents who were grouped into three: the bilateral normal disc position group, the unilateral or bilateral functional disc displacement group, and the unilateral or bilateral functional disc dislocation group. We compared the extent of VMD and LMD between the three groups, and investigated their correlation with age. Results indicate that functional disc displacement and dislocation are related to mandibular displacement, and VMD did not correlate with age but LMD did correlate with age. This study suggests that the onset of disc displacement is related to the mandibular displacement and disturbs normal growth of the mandible three-dimensionally.
