Several studies have shown that there is a Indirect ophthalmoscopy with the head large interobserver and intraobserver variability in esti mates of the C/D ratio, even among experts. The slit-lamp biomicroscope with hand-held lenses, such as the Goldmann, the Zeiss, the 78D, and the 90D lenses, offers tremendous advantages in evaluating the details of the optic nerve head. Its main disadvantage is the nerve head, which can be next best to a photograph direct contact with the cornea and the need for a viscous (Fig. The Zeiss 4-mirror of the neural rim, such as pallor, sloping, focal thinning lens has similar advantages, but uses only a tear film and notching, and disc hemorrhages.

However, monoscopic pho skillful, direct ophthalmoscopy, which provides greater tographs may not be ideal for detecting subtle neural rim magnification. Solid lines represent inner and outer edges of the neural rim, and radiating lines are used to indicate sloping of the neural rim.

Nonsimultaneous images can be obtained However, disc size is usually symmetrical between by having the patient shift fixation, or by shifting the cam the two eyes. In addition, the C/D ratio and neural rim era position between photographs to obtain the stereo configuration tend to be symmetrical in normal subjects.

Recognizing that these treatment categories are broad and encompass a range of more specific interventions anxiety symptoms help discount lexapro 20 mg fast delivery, we modeled each specific intervention as a random effect anxiety medication names order lexapro canada. Results from our quantitative analysis indicated that the probability of being best was 43 percent for both multicomponent interventions and for interventions with only a parent component zantac anxiety symptoms cheap lexapro 20 mg otc. The probability of being best was 14 percent for interventions with only a child component anxiety 4 months postpartum cheap lexapro 10mg overnight delivery. Although we considered age-by-treatment interactions, there was not enough balance among the age and treatment combinations to include them in the final model. Only one study was federally funded; the rest were industry sponsored or partially funded by a pharmaceutical company. Parent-rated quality of life improved significantly in the atomoxetine group (mean change, 2. Effectiveness of Combined Psychosocial and Pharmacologic Interventions Compared With Individual Interventions No head-to-head studies were identified that assessed the comparative effectiveness of combination interventions. Harms of Psychosocial or Pharmacologic Interventions Harms of psychosocial interventions are not reported in the literature. Studies were powered for effectiveness and not for detection of harms, so harms may be underrepresented in the published literature. Generally, harms reported in included studies were mild or moderate and immediate in nature. Nonetheless, there was significant loss to followup in several pharmacologic studies, some of which was likely due to adverse events. In effectiveness studies included in this report, frequently occurring adverse events associated with risperidone included weight gain, sedation, and somnolence. In the largest risperidone study (n = 527), the percent of participants experiencing weight gain ranged from 1. At least 35 percent of children in the acute, continuation, and maintenance risperidone dosing phases and those receiving placebo experienced an adverse event, and extrapyramidal symptoms occurred in less than 2 percent of participants in each phase. Decreased mental alertness, diminished emotional expression, and diminished facial expression occurred significantly more frequently in the placebo group than with quetiapine (p values 0. Adverse events associated with mixed amphetamine salts included sleep delay, insomnia, and anorexia, with mean weight loss ranging from 1. One study of methylphenidate also reported delayed sleep but did not present harms data. Rates of harms from those sources were typically higher than rates of harms reported in the short-term effectiveness studies and may provide a more complete picture of potential harms. They do not, however, place the harms data in the context of tradeoffs with effectiveness. This question was divided into subquestions about variations in intervention effectiveness due to (a) patient characteristics, (b) characteristics of the disorder, (c) patient treatment history, and (d) treatment characteristics. It is unclear if studies identified as examining these questions were adequately powered to answer them. We identified 12 studies examining variations in psychosocial intervention effectiveness due to patient characteristics. In general, results were inconsistent, although some evidence exists that the child’s sex, maternal characteristics such as depression and anger, and other family functioning variables are associated with the effectiveness of some psychosocial interventions. One study of preschool children reported that greater severity of behavior problems was associated with greater improvements, but no effect of baseline severity was reported in another study. In a study of school-age children, concomitant developmental delay was associated with less effectiveness of the intervention. In two studies including adolescents, lower levels of psychopathology were associated with better disruptive behavior outcomes. No studies examined whether the effectiveness of psychosocial interventions varied by patient treatment history. For psychosocial interventions that include a parent component, either alone or in combination with other components, there is some evidence suggesting that improved parenting practices partially mediate effectiveness. Improvements in child outcomes were associated with positive parenting changes in three studies of preschool children and in three of four studies of school-aged children. Few studies of pharmacologic interventions reported moderator or mediator analyses. One study indicated that atomoxetine was more effective in patients who had previously been treated with a stimulant than in patients who had not. Discussion Key Findings Sixty-six studies examined the effectiveness of psychosocial interventions for children with disruptive behaviors. About half of the studies (n = 25) were conducted in the United States; the remaining studies were conducted in Australia (n = 11), Canada (n = 4), Germany (n = 3), Ireland (n = 2), Israel (n = 2), Italy (n = 1), Netherlands (n = 5), Norway (n = 4), Puerto Rico (n = 1), Sweden (n = 3), and the United Kingdom (n = 5). Twenty-three studies examined psychosocial interventions with preschool-age children, 29 studies examined psychosocial interventions with school-age children, and 14 studies examined psychosocial interventions with adolescents. In general, studies provided consistent evidence that each of these interventions resulted in significantly greater improvement on parent reports of child disruptive behavior than controls. In general, these studies provided consistent evidence that each of these interventions resulted in significantly greater improvement on parent reports of child disruptive behavior than controls. Results from our Bayesian multivariate mixed-treatment (network) meta-analysis were generally consistent with our qualitative synthesis. Results indicated that the probability of having the largest effect was the same for multicomponent interventions (43%) and interventions with only a parent component (43%). The probability of having the largest effect was 14 percent for interventions with only a child component. Despite a fairly robust literature on psychopharmacologic drugs as a whole, we identified only 13 studies evaluating short-term outcomes of pharmacologic interventions for inclusion in our review. Studies of antipsychotic medications and valproic acid, an antiepileptic medication, had mixed results over the short term. No head-to-head studies were identified that compared the effectiveness of combined psychosocial and medical interventions or that compared the effectiveness of psychosocial interventions with medical interventions. The pharmacologic treatment studies in this report were generally small and short term, with typically no followup post-treatment. Nonetheless, there was significant loss to followup in several studies, some of which was likely due to experiencing adverse events, and we therefore sought harms data from other sources that might include more extensive and longer term data, including other systematic reviews. Adverse events associated with risperidone were generally mild across studies, with weight gain, sedation, and somnolence frequently reported. Adverse events associated with mixed amphetamine salts included sleep delay, insomnia, and anorexia. Although we identified studies that examined whether variations in intervention effectiveness due to (a) patient characteristics, (b) characteristics of the disorder, (c) patient treatment history, and (d) treatment characteristics could be found, it is not clear that the studies were adequately powered to answer these questions. Studies are relatively homogeneous with respect to child age, perhaps implicitly recognizing the potential for child age to modify the effectiveness of both psychosocial and pharmacologic interventions. Twelve studies were identified that examined variations in psychosocial intervention effectiveness due to patient characteristics. In general, results were inconsistent, although some evidence exists that the sex of the child, maternal characteristics such as depression and anger, and other family functioning variables are associated with the effectiveness of some psychosocial interventions. Some studies suggested that difficult temperament in preschool children and psychopathy in teenagers modified the effectiveness of psychosocial interventions. No studies examined whether the effectiveness of psychosocial interventions varied by patient treatment history, and one study reported that atomoxetine was more effective in patients who had previously been treated with a stimulant than it was in patients who had not. Potential mediators of treatment effect were most thoroughly examined in the literature on psychosocial interventions. The variables most commonly examined include baseline severity of symptoms, intervention dose, and positive parenting. In general, there is some support that each of these variables may mediate intervention effectiveness, but results were inconsistent. We identified 22 reviews assessing the effectiveness of psychosocial interventions and 2 reviews assessing the effectiveness of pharmacologic interventions. Tables A and B (and Tables 49-51 in the full report) summarize the strength of the evidence and provide the assessment of the risk of bias, consistency of findings across trials, directness of the evidence, and precision of the estimate provided by the literature. We assessed strength of evidence for the effectiveness of interventions using the qualitative and quantitative approaches described in the Methods section. Parent reports of child intervention on disruptive behavior outcomes were child behavior consistently improved in parenting intervention arms compared with wait-list or treatment-as-usual controls.
