Abstract
This paper reviews the evidence base supporting the use of pharmacological treatments for child and adolescent psychiatric disorders. Recent advances in knowledge are highlighted, with some of the controversies. New evidence supports a role for selective serotonin reuptake inhibitors in the treatment of anxiety disorders and obsessive–compulsive disorder. Educational and behavioural approaches remain the mainstay of treatment for children and adolescents with autism, but there is evidence that adjunctive medication may be effective. Atypical antipsychotics have been investigated in the treatment of Tourette syndrome and early-onset schizophrenia. Many questions remain unanswered and further research is needed in all areas of paediatric psychopharmacology.

Abstract
Combined dyslipidemia (CD) is now the predominant dyslipidemic pattern in childhood, characterized by moderate-to-severe elevation in triglycerides and non-high-density lipoprotein cholesterol (non-HDL-C), minimal elevation in low-density lipoprotein cholesterol (LDL-C), and reduced HDL-C. Nuclear magnetic resonance spectroscopy shows that the CD pattern is represented at the lipid subpopulation level as an increase in small, dense LDL and in overall LDL particle number plus a reduction in total HDL-C and large HDL particles, a highly atherogenic pattern. In youth, CD occurs almost exclusively with obesity and is highly prevalent, seen in more than 40% of obese adolescents. CD in childhood predicts pathologic evidence of atherosclerosis and vascular dysfunction in adolescence and young adulthood, and early clinical cardiovascular events in adult life. There is a tight connection between CD, visceral adiposity, insulin resistance, nonalcoholic fatty liver disease, and the metabolic syndrome, suggesting an integrated pathophysiological response to excessive weight gain. Weight loss, changes in dietary composition, and increases in physical activity have all been shown to improve CD significantly in children and adolescents in short-term studies. Most importantly, even small amounts of weight loss are associated with significant decreases in triglyceride levels and increases in HDL-C levels with improvement in lipid subpopulations. Diet change focused on limitation of simple carbohydrate intake with specific elimination of all sugar-sweetened beverages is very effective. Evidence-based recommendations for initiating diet and activity change are provided. Rarely, drug therapy is needed, and the evidence for drug treatment of CD in childhood is reviewed.

Abstract
UNLABELLED Although paediatric patients frequently suffer from intoxications with atypical antipsychotics, the number of studies in young children, which have assessed the effects of acute exposure to this class of drugs, is very limited. The aim of this study was to achieve a better characterization of the acute toxicity profile in young children of the atypical antipsychotics clozapine, olanzapine, quetiapine, and risperidone. We performed a multicentre retrospective analysis of cases with atypical antipsychotics intoxication in children younger than 6 years, reported by physicians to German, Austrian, and Swiss Poisons Centres for the 9-year period between January 1, 2001 and December 31, 2009. One hundred and six cases (31 clozapine, 29 olanzapine, 12 quetiapine, and 34 risperidone) were available for analysis. Forty-seven of the children showed minor, 28 moderate, and 2 severe symptoms. Twenty-nine cases were asymptomatic. No fatalities were recorded. Symptoms predominantly involved the central nervous and cardiovascular systems. Minor reduction in vigilance (Glasgow Coma Scale score >9) (62 %) was the most frequently reported symptom, followed by miosis (12 %) and mild tachycardia (10 %). Extrapyramidal motor symptoms were observed in one case (1 %) after ingestion of risperidone. In most cases, surveillance and supportive care were sufficient to achieve a good outcome, and all children made full recovery. CONCLUSIONS Paediatric antipsychotic exposure can result in significant poisoning; however, in most cases only minor or moderate symptoms occurred and were followed by complete recovery. Symptomatic patients should be monitored for central nervous system depression and an electrocardiogram should be obtained.

Abstract
This paper provides a selective overview of the past, present and future of pediatric psychopharmacology. The acceptance of medication use in child psychiatry was based on the results of double-blind, placebo-controlled trials documenting the efficacy of drug treatments for attention-deficit/hyperactivity disorder, enuresis, depression, anxiety disorders, obsessive-compulsive disorder and psychoses. This period of success was followed by a series of challenges, including a growing awareness of the long-term adverse effects of medications and of the inadequacy of long-term drug surveillance. There is great concern today that children are being overtreated with medication, especially in the US. Further advances in pediatric psychopharmacology may come from examination of large medical data sets including both pharmacological and psychiatric information, which could lead to drug repurposing, as well as from preclinical translational studies such as those using human induced pluripotent stem cells.

Abstract
OBJECTIVE This review reports the incidence of hyperprolactinemia, its relationship with genotype, and prolactin-related side effects in children and adolescents treated with antipsychotics. METHOD Data on prolactin levels were available for haloperidol, pimozide, risperidone, olanzapine, clozapine, ziprasidone, and quetiapine. Twenty-nine studies were selected after a literature search in the English Medline/Embase/Psychinfo/EBM databases (1965 to August, 2008). RESULTS All antipsychotics, except clozapine, ziprasidone, and quetiapine, increase the mean prolactin level from baseline values of 8.0 ng/mL to 25-28 ng/mL after 4 weeks of treatment (reference range 0-15 ng/mL). The most and best data are available for risperidone. Five risperidone studies (n = 577) show an increase of prolactin level from 7.8 ng/mL to 17.7 ng/mL after 1 year of treatment, and two risperidone studies (n = 60) show an increase from 7.4 ng/mL to 24.9 ng/mL after 2 years of treatment. Aggregated over all antipsychotics, prolactin-related side effects, such as gynecomastia, galactorrhea, irregular menses, and sexual dysfunction, were reported by 4.8% of the children and adolescents. No data are available on bone mineral density in relation to antipsychotic-induced hyperprolactinemia in children and adolescents. Prolactin levels may be influenced by the genetic differences that influence prolactin metabolism and D2 dopamine receptor density. CONCLUSION Persistent elevation of prolactin for periods up to 2 years has been documented in maintenance treatment with risperidone. Very limited long-term data of pimozide, olanzapine, and quetiapine prohibit drawing conclusions for these antipsychotics. Systematic long-term observational studies, including specific questionnaires as well as physical examination, are needed to investigate prolactin-related side effects of antipsychotic treatment in children and adolescents.

Abstract
OBJECTIVE The aim of this study was to examine whether quetiapine is superior to placebo in the treatment of adolescents with conduct disorder. METHODS This was a 7-week, randomized, double-blind, placebo-controlled pilot study with two parallel arms. Nine youths were randomly assigned to receive quetiapine, and 10 youths were randomly assigned to receive placebo. Patients were assessed weekly throughout the trial. Quetiapine was dosed twice daily, and medications could be titrated flexibly through the end of study week 5. The dose was fixed for the final 2 weeks of the study. The primary outcome measures were the clinician-assessed Clinical Global Impressions-Severity (CGI-S) and-Improvement (CGI-I) scales. Secondary outcome measures included parent-assessed quality of life, the overt aggression scale (OAS), and the conduct problems subscale of the Conners' Parent Rating Scale (CPRS-CP). RESULTS The final mean dose of quetiapine was 294 +/- 78 mg/day (range 200-600 mg/day). Quetiapine was superior to placebo on all clinician-assessed measures and on the parent-assessed quality of life rating scale. No differences were found on the parent-completed OAS and CPRS-CP. Quetiapine was well tolerated. One patient randomized to quetiapine developed akathisia, requiring medication discontinuation. No other extrapyramidal side effects occurred in patients receiving active drug. CONCLUSIONS This methodologically controlled pilot study provides data that quetiapine may have efficacy in the treatment of adolescents with conduct disorder. Because of the preliminary nature of the study, further research with larger samples is needed to confirm these findings.

Abstract
OBJECTIVE The aim of this study was to assess effectiveness and tolerability of oral olanzapine treatment of adolescents with schizophrenic disorders. METHOD Adolescent patients (12-19 years) with schizophrenia, schizoaffective, or schizophreniform disorders according to the Diagnostic and Statistical Manual of Mental Disorders, 4(th) edition (DSM-IV) were enrolled in a multicenter, prospective, open-label study. Following a 2- to 9-day washout period, patients initially received 10 mg/day olanzapine. Dose modification was allowed during week 2 (dose range 5-15 mg/day) and during weeks 3-6 (dose range, 5-20 mg/day). Responders (improvement > or =30% on the Brief Psychiatric Rating Scale, BPRS) continued olanzapine for additional 18 weeks. Psychopathology was assessed using BPRS and Clinical Global Impressions (CGI) scales; side effects were assessed by adverse event reporting. RESULTS Out of 96 patients enrolled at 10 sites, 60 (62.5%) met response criteria at week 6. Mean BPRS total scores decreased significantly (p < 0.001) from baseline (39.2 +/- 13.4) to week 6 last observation carried forward (LOCF) (22.2 +/- 14.7). The rate of patients considered markedly ill or worse (CGI-S) decreased from 83.3% (baseline) to 37.5% (week 6, LOCF). The most common reported adverse event was weight gain (30.2%, 29/96). Three patients (3.1%) discontinued due to adverse events. CONCLUSIONS In this study of young patients with schizophrenia, schizoaffective, or schizophreniform disorders, olanzapine treatment was associated with marked symptom improvement. As changes in weight and prolactin levels may be greater in adolescent than in adult patients, potential risks and benefits of olanzapine treatment in adolescents should be considered carefully.

Abstract
BACKGROUND Atypical antipsychotics could be replacing traditional antipsychotics in the treatment of childhood disorders. METHOD A postal survey was conducted of Child Psychiatrists in a region of the United Kingdom to evaluate their use of atypical antipsychotics for psychotic and non-psychotic conditions. RESULTS 97% of respondents reported prescribing atypical antipsychotics and at least 65% did so for non-psychotic indications although several concerns were raised. Differences in prescribing and monitoring practices between Community and Specialist services were noted. CONCLUSIONS Atypical antipsychotics appear to play a significant role in current child psychiatry practice. Further discussions and research needs to occur about their use and guidelines produced.

Abstract
OBJECTIVE The aim of this study was to improve and evaluate the practibility of a method for the assessment of drug-associated side effects, and we implemented a clinical drug monitoring for atypical neuroleptics. METHODS Side effects of initially hospitalized patients treated with clozapine (n = 16), olanzapine (n = 16), and risperidone (n = 19) were prospectively monitored on a weekly basis for the first 3 weeks. In the case of stable medication, measurements of all variables were made every 4 weeks or upon discharge. We used the Dosage Record Treatment Emergent Symptom Scale (DOTES) in a supplemented version to measure the presence and severity of side effects. RESULTS Drowsiness and decreased motor activity were common, especially in the first 2 weeks. Orthostatic hypotension, increased salivation, constipation, and nasal congestion were seen in more than 30% to 60% of patients treated with clozapine and were less common in adolescents treated with olanzapine and risperidone. Rigidity, tremor, and dystonia were seen in 5% to 15% of patients treated with risperidone and olanzapine. The average weight gain after 6 weeks of treatment with the atypical neuroleptics was significantly higher for the olanzapine group (4.6 +/- 1.9 kg) than for the risperidone (2.8 +/- 1.3 kg) and clozapine (2.5 +/- 2.9 kg) groups. CONCLUSIONS The authors' supplemented DOTES version is generally applicable to clinical use in mental health centers. The differences among the side effects of these three agents may affect compliance with medication and medical risks of metabolic syndrome, diabetes, and cardiovascular disease. More research on the short- and long-term safety of psychotropic drugs in children and adolescents, using standardized methods, should be considered.

Abstract
In France, psychotropic drugs may be classified in four categories according to their official data. The first category corresponds to psychotropic drugs with an approved indication available in paediatry. Theyare old agents (e.g. haloperidol, amitriptyline, benzodiazepines...) with the exception of methylphenidate (hyperactivity). The second one corresponds to pharmacological agents approved for some indications obtained with adults but not for a1l (i.e. restricted indication: e.g. sertraline approved in paediatry only for OCD but not for depression, risperidone approved only for the treatment of disruptive behaviors in children with subaverage IQs). For the third category, the psychotropic agent is either contraindicated or unadvised under the age of 15 or 18 years, by lack of data (e.g. most of SSRI or atypical antipsychotic drugs). For the last category, official data available in brief summaries offer no information on paediatric use and consequently their administration does not appear possible. Up to now, no approved use has been delivered to injection route (IM or IV) in France, except for an IM formulation of zuclopenthixol. Prescribing psychotropic drug has to respect good practices including close psychological and somatic monitoring that associates the young patient and his relative (psycho-education program). Particular key-points should be taken into consideration (i.e. pharmacokinetic and physiological specificities, risk of false passage under the age of 6 years with capsules or tablets, presence of alcohol in some oral solution or bitter aroma...). Beside these official data, many studies have been published but must be carefully interpreted according to their level of pertinence. Meta-analysis gather all randomised controlled trials published or not, analyse their specific pertinence and thus provide clinically relevant elements. Randomised controlled trials present clinical interest but key-points in study design must be checked (e.g. number of patients, inclusion and exclusion criteria, length of the study and clinical relevance of clinical scales...). Other studies like open trials or clinical cases do not offersufficient guarantees. Some randomised controlled trials of clinical relevance have been carried out in this population with new pharmacological classes (eg SSRI, atypical antipsychotic drugs) and may lead to extended indications in children and adolescents. According to bibliographic and official data, the main criteria in the prescribing choice may take into consideration the following sis stressing a poor benefit/risk ratio. SSRI may offer better prospects but their use has not been approved in this indication, until now. In OCD, sertraline shows great interest to enhance clinical response and represents the molecule of reference. No drug has been approved for mood disorders in children or adolescent, in France, contrary to USA where lithium can be administered over the age of 12 years. In addition, antiepileptic drugs like carbamazepine or divalproate have conducted to clinical improvement in some studies. Benzodiazepines, hydroxyzine and meprobamate use should be strictly restricted in case of anxiety symptoms but are the only agents approved in this indication despise promising results obtained with SSRI. Transitory insomnia may take advantage of alimemazine prescription (approved use over the age of 36 months). Some typical neuroleptics are indicated in tics or in behaviour disorders associated to autism or related syndromes but present clinical limitations and poor tolerability. Promising clinical trials (randomised or not) have been conducted with new atypical antipsychotic drugs like risperidone. In conclusion, present data available for paediatric use of psychotropic agents emphasizes that safety and effectiveness are not always well established in particular for the treatment of chronic disorders (long term tolerability assessment). Moreover, studies should be carried out to specify factors promoting adherence and quality of life for this young population in order to optimise clinical benefit of drug prescription.

Abstract
Although the atypical antipsychotic olanzapine is increasingly being used in child and adolescent psychiatry, reports of olanzapine overdose in this young population are scarce. We report on two cases of adolescents who attempted suicide with an overdose of olanzapine: (1) A 14-year-old female ingested 275 mg olanzapine, which produced the highest reported nonlethal serum level (1503 ng/mL) and caused somnolence, agitation (acutely), and extrapyramidal symptoms (EPS; after 54 hours) but no major clinical complications. The serum olanzapine level dropped to 129 ng/mL within 48 hours; and (2) a 17-year-old male ingested 400 mg olanzapine, the highest reported nonlethal dose of olanzapine in adolescents, which produced respiratory suppression requiring intubation and mechanical ventilation; he recovered after 3 days. Based on clinical monitoring and postmortem data, the 2 patients survived the ingestion of high doses of olanzapine. We also provide a review of the literature, encompassing all reported cases of olanzapine overdose in children and adolescents and discuss symptoms, diagnosis, and treatment options, based on pharmacokinetic and pharmacodynamic considerations.

Abstract
The objective of this review is to summarize the data about metabolic side effects of atypical antipsychotics in children. Original research articles about side effects of atypical antipsychotics used in children were reviewed. The data was obtained mainly through Medline searches, identifying articles focusing on the use of atypical antipsychotics in children. Forty studies that addressed the issue of metabolic side effects were selected. The use of atypical antipsychotics in children has been consistently associated with weight gain and moderate prolactin elevation, while only a few case reports address the issue of glucose dysregulation and dyslipidaemia. The risk of weight gain and hyperprolactinaemia might be higher in younger children. Other risk factors have also been associated with antipsychotic-induced metabolic disturbances. These changes seem to be reversible, at least in some cases. Metabolic side effects of atypical antipsychotics could lead to serious complications in children who are prescribed these medications. Serious considerations should be given before initiating treatment and consistent clinical monitoring is essential. More research is needed, especially regarding glucose dysregulation and dyslipidaemia.

Abstract
OBJECTIVE We reviewed available pediatric literature on second-generation antipsychotic medications to assess current evidence of efficacy and safety. METHOD An English language MEDLINE search (1974-2003) was conducted using key words-atypical antipsychotics, children and adolescents, toxicity, clozapine, risperidone, olanzapine, quetiapine, ziprasidone, and aripiprazole. Additional efficacy and safety data were obtained from drug manufacturers. RESULTS We identified 176 reports, including 15 double-blind, controlled trials, 58 openlabel studies, 18 retrospective chart reviews, and 85 case series/reports. The majority of these studies (43%) were of risperidone. Evidence suggests that second-generation antipsychotics are efficacious in the treatment of psychosis, bipolar disorders, pervasive developmental disorders, and Tourette's Disorder, and are potentially useful in mental retardation, conduct disorder, and severe attention deficit hyperactivity disorder (ADHD). The most frequently reported side effects included cardiovascular effects, weight gain, sedation, sialorrhea, extrapyramidal signs, and hyperprolactinemia, although the relative frequencies of these untoward effects vary among medications. CONCLUSION Although the evidence base for pediatric use of second-generation antipsychotics is expanding, the majority of available studies are anecdotal, or short-term, openlabel trials. Reports suggest that these compounds are effective for a variety of psychiatric disorders in children and adolescents, but additional double-blind, controlled studies are required to establish definitive efficacy. Although these medications appear to be well tolerated in short-term studies, long-term follow-up investigations and ongoing clinical monitoring are necessary to confirm their safety in this age group.

Abstract
Atypical antipsychotics are now the most commonly prescribed antipsychotics in young patients. These drugs are increasingly being used because of better tolerance and safety as seen in the adult populations. Youth with more severe psychopathology who are treated in the inpatient setting have been overlooked in much of the published research, and the extent of use and rationale in this population is unknown. This naturalistic retrospective study examined a population of adolescents in an inpatient state hospital setting with regard to their use of atypical antipsychotics. All patients who received an inpatient prescription for atypical antipsychotics between January 1, 1997 and June 1, 2000 and were ages 18 or younger at the time of medication initiation were included in the study. Twenty-three percent (88/380) of patients received an atypical antipsychotic: 68% (60/88) risperidone, 27% (24/88) olanzapine, and 5% (4/88) quetiapine. Psychotic disorders were considered as the primary diagnosis in only 17% of patients treated with atypical antipsychotics, and no particular diagnosis was predictive of monotherapy with an atypical antipsychotic. In the adolescent populations, atypical antipsychotics are being used for a wide variety of diagnoses and are commonly used adjunctively (more than 80%) with many concomitant psychotropic medications. More research is needed to develop useful and specific practice guidelines in children and adolescents for these commonly used medications.

Abstract
Evidence on the efficacy and safety of atypical antipsychotics in children and adolescents with schizophrenia is limited. The purpose of this review is to assess the published data on the use of atypical antipsychotics in children and adolescents with schizophrenia alone and with comorbid disorders, and to establish benefit-risk guidelines for clinicians.Risperidone, olanzapine and clozapine were found to be effective in the treatment of aggression and mania. Risperidone, and possibly also olanzapine, may be the drugs of choice in children with comorbid tic disorders. Ziprasidone has some monoamine reuptake inhibition properties and may be administered as an augmenting agent in children and adolescents with schizophrenia and comorbid anxiety and mood disorders. Compared with the typical antipsychotics, the atypical drugs seem to be more effective, better tolerated and lead to better patient adherence. Importantly, the atypical antipsychotics have a lower propensity to induce extrapyramidal symptoms and a potential (shown so far only in adults) to improve cognitive function and inhibit suicidal behaviour (especially clozapine). Yet, the adverse effects associated with these agents, especially weight gain, which may also have long-term effects, can lead to non-compliance in the young population. In children and adolescents receiving clozapine, olanzapine and quetiapine (but not ziprasidone, which does not have a pro-appetite effect), particularly those with obesity or a family history of diabetes mellitus, fasting blood glucose and lipid levels must be monitored frequently. Weight gain might be better controlled when the children and their parents are properly informed about this adverse effect and diet is regulated. Another major disadvantage of the atypical antipsychotics, especially risperidone, is their association with hyperprolactinaemia, which can lead to hypogonadism-induced osteoporosis, galactorrhoea, gynaecomastia, irregular menstruation and sexual dysfunction, all seen also with typical antipsychotics. Other atypical antipsychotics, namely olanzapine and ziprasidone, have been reported to be prolactin sparing in adults, but may not be completely devoid of hyperprolactinaemic effects in children and adolescents. Thus, prolactin levels should be assessed routinely in young patients treated with atypical antipsychotics. Further, children and adolescents with hyperprolactinaemia-related effects should be switched to a prolactin-sparing agent, such as quetiapine. All atypical antipsychotics may induce sedation and they are not devoid of extrapyramidal symptoms (especially risperidone). The use of typical antipsychotics has been limited to patients who are resistant to atypical antipsychotics, intolerant to their adverse effects, or require injections or depot preparations. Further double-blind, placebo-controlled trials and long-term safety assessments are needed before definitive conclusions can be reached about the place of atypical antipsychotics in the therapeutic armamentarium of childhood-onset schizophrenia.

Abstract
BACKGROUND Olanzapine is an atypical antipsychotic that has efficacy in adults with psychotic disorders. This preliminary study examined the effectiveness of olanzapine in adolescents with schizophrenia or its related conditions. METHOD Adolescents aged 12-17 years (inclusive) with a diagnosis of schizophrenia, schizoaffective, or schizophreniform disorder were enrolled in this 8-week, open-label, outpatient study. The Positive and Negative Syndrome Scale (PANSS), the Clinical Global Impressions Scale (CGI), and the Children's Global Assessment Scale (CGAS) were administered as outcome measures. Extrapyramidal side effects were assessed at each visit. Olanzapine was initiated at a dose of 2.5 mg/day and could be increased to a maximum total daily dose of 20 mg. RESULTS Sixteen participants with a mean age of 13.8 (SD = 1.5) years were treated. Significant improvements were found in the PANSS, CGI severity, and CGAS scores. Reductions in both positive and negative symptoms were found. Increased appetite and sedation were the most frequently reported side effects. Two subjects required treatment for extrapyramidal side effects. CONCLUSIONS Psychotic symptoms significantly improved during study. Overall, olanzapine was well tolerated. Future studies are needed to confirm these findings, to assess long-term treatment outcomes, and to compare the effectiveness of olanzapine with that of other antipsychotics.

Abstract
OBJECTIVE To develop treatment recommendations for the use of antipsychotic medications for children and adolescents with serious psychiatric disorders and externalizing behavior problems. METHOD Using a combination of evidence- and consensus-based methodologies, recommendations were developed in six phases as informed by three primary sources of information: (1) current scientific evidence (published and unpublished), (2) the expressed needs for treatment-relevant information and guidance specified by clinicians in a series of focus groups, and (3) consensus of clinical and research experts derived from a formal survey and a consensus workshop. RESULTS Fourteen treatment recommendations on the use of atypical antipsychotics for aggression in youth with comorbid psychiatric conditions were developed. Each recommendation corresponds to one of the phases of care (evaluation, treatment, stabilization, and maintenance) and includes a brief clinical rationale that draws upon the available scientific evidence and consensus expert opinion derived from survey data and a consensus workshop. CONCLUSION Until additional research from controlled trials becomes available, these evidence- and consensus-based treatment recommendations may be a useful approach to guide the use of antipsychotics in youth with aggression.

Abstract
OBJECTIVES To review the evidence for the safety and efficacy of nonpharmacological and pharmacological treatments for aggression in children and adolescents. METHOD and searches (1990-present) were conducted for double-blind, placebo-controlled studies of atypical antipsychotics for aggression and for literature on the use of other pharmacological agents and psychosocial interventions for aggression. Case reports and adult literature regarding the safety of atypical antipsychotics were used where controlled data for youth were lacking. RESULTS Controlled data on the treatment of aggression in youth is scarce. Psychosocial interventions may be effective alone or in combination with pharmacological treatments. Psychotropic agents (e.g., stimulants, mood stabilizers, beta-blockers) have also been shown to have limited efficacy in reducing aggression. Antipsychotics, particularly the atypical antipsychotics, show substantial efficacy in the treatment of aggression in selected pediatric populations. Atypical antipsychotics are generally associated with fewer extrapyramidal symptoms than are typical antipsychotics. CONCLUSIONS Psychosocial interventions and atypical antipsychotics are promising treatments for aggression in youth. Double-blind studies should examine the safety and efficacy of atypical antipsychotics compared to each other and to medications from other classes, the efficacy of specific medications for different subtypes of aggression, combining various psychotropic medications, optimal dosages, and long-term safety.

Abstract
STUDY OBJECTIVE To explore the clinical characteristics of hyperglycemia in patients treated with olanzapine. DESIGN Retrospective, epidemiologic survey of spontaneously reported adverse events related to olanzapine therapy SETTING Government-affiliated drug evaluation center. PATIENTS Two hundred thirty-seven patients with olanzapine-associated diabetes or hyperglycemia. INTERVENTION One hundred ninety-six cases from January 1994-May 15, 2001, were identified with the United States Food and Drug Administration's MedWatch Drug Surveillance System, and 41 cases published through May 15, 2001, were identified with MEDLINE or through meeting abstracts. MEASUREMENTS AND MAIN RESULTS Of the 237 cases, 188 were new-onset diabetes, 44 were exacerbations of preexistent disease, and 5 could not be classified. Mean patient age for newly diagnosed cases was 40.7+/-12.9 years and male:female ratio was 1.8. Seventy-three percent of all cases of hyperglycemia appeared within 6 months of start of olanzapine therapy. Eighty patients had metabolic acidosis or ketosis, 41 had glucose levels of 1000 mg/dl or greater, and 15 patients died. When olanzapine was discontinued or the dosage decreased, 78% of patients had improved glycemic control. Hyperglycemia recurred in 8 of 10 cases with rechallenge. CONCLUSIONS Number of reports, temporal relationship to start of olanzapine therapy, relatively young age, and improvement on drug withdrawal suggest that olanzapine may precipitate or unmask diabetes in susceptible patients.

Abstract
Antipsychotics are frequently used in the treatment of a variety of neuropsychiatric conditions in children and adolescents. Atypical antipsychotics have come to the forefront in child psychiatry due largely to their tolerability profiles as well as their efficacy. Potential treatment options include clozapine, risperidone, olanzapine, quetiapine and ziprasidone. A number of studies investigating the use of clozapine have been published in children; however, owing to the frequent monitoring required for agranulocytosis, the use of clozapine may be restricted to patients with treatment-refractory disease. With accumulating data on the development of glucose intolerance in adults receiving clozapine, closer monitoring of bodyweight and fasting blood glucose is imperative. Clozapine also has an increased seizure risk, therefore a baseline electroencephalogram should be performed, as well as continued vigilance for this adverse effect. Risperidone is an atypical antipsychotic that is generally well tolerated and numerous studies have been published investigating this drug in children. Unlike clozapine, its receptor interaction profile lends itself toward increased risk of extrapyramidal symptoms (EPS) and hyperprolactinaemia. Bodyweight gain is a common adverse effect, although somewhat less than that reported with olanzapine. Baseline liver function studies prior to initiation of this medication are recommended. Risperidone-induced mania has been reported in adults and, therefore, increased caution should be used when deciding to treat children and adolescents with risperidone, particularly in those with a predisposition toward mania. Olanzapine, like risperidone, has also been associated with onset of mania in adults. Olanzapine has a receptor profile that results in significant risk for bodyweight gain and sedation. Furthermore, this drug has been linked to the development of glucose intolerance; thus, it is important to monitor bodyweight and fasting blood glucose on a frequent basis. Less information is known about quetiapine in children and adolescents. Reports about its efficacy and tolerability vary. Quetiapine appears to have increased risk for sedation and bodyweight gain, albeit less than that of olanzapine. The compound appears to be less likely to induce EPS. Finally, ziprasidone has recently been approved for use in the adult population. This compound, in terms of its receptor profile, has more in common with risperidone. This suggests a potential for increased risk of EPS and hyperprolactinaemia. It also has an increased risk of QTc prolongation; thus, a baseline electrocardiogram is suggested, particularly in those patients with a history of cardiovascular illness. Lack of evidence for bodyweight gain with ziprasidone is a considerable advantage.

Abstract
There are no medications that are specifically marketed for the treatment of autism. There does exist, however, an extensive body of literature describing both open-label and controlled studies of medications in the treatment of both children and adults with autism. Some of the better-studied medications (including haloperidol and risperidone) are often efficacious in treating associated symptoms of autism but can also cause unacceptable adverse effects. Early studies of serotonin re-uptake inhibitors appear promising but may not be indicated for all age groups. Small, controlled studies of methylphenidate and clonidine indicate a possible role for these medications in the treatment of hyperactivity in autism. No medications have been proven to be efficacious in the treatment of the core social or communication impairment seen in autism. Current pharmacological management is best aimed at target symptoms that have been demonstrated to respond to medication in treatment studies.

Abstract
This article critically reviews research done in the past 2 years concerning the pathophysiology and treatment of autism. Recent research in genetics, neuroimaging, neurochemistry, and pharmacologic treatment has advanced the body of knowledge about the pathophysiology of autism. Relatively new imaging technologies (eg, positron emission tomography) are increasingly being applied to the study of subjects with autism and have produced promising results that await replication. Neurochemical and challenge studies continue to suggest a role for 5-HT dysregulation in autism. Additional research is needed to determine the role of neuroendocrine and autoimmune factors in autism. Significant gains have been made in determining which pharmacologic treatments are efficacious in autism. Additional research is needed on agents that might ameliorate the core and associated symptoms of autism.
