Current biodegradation screening tests are not specifically designed for persistence assessment of chemicals, often show high inter- and intra-test variability, and often give false negative biodegradation results. Based on previous studies and recommendations, an international ring test involving 13 laboratories validated a new test method for marine biodegradation with a focus on improving the reliability of screening to determine the environmental degradation potential of chemicals. The new method incorporated increased bacterial cell concentrations to better represent the microbial diversity; a chemical is likely to be exposed in the sampled environments and ran beyond 60 days, which is the half-life threshold for chemical persistence in the marine environment.

To classify the fate and behaviour of these compounds in the environment, a series of international standardised biodegradation screening tests (BSTs) were developed over 30 years ago.

Objective: This study examined the role of lithium in the maintenance treatment of pediatric patients with bipolar I disorder (BP-I).
Method: Participants aged 7 to 17 years who presented with a manic or mixed episode received 24 weeks of lithium treatment in one of two multiphase studies, the Collaborative Lithium Trials (CoLT 1 and CoLT 2). Responders were randomized to continue lithium or to be cross-titrated to placebo for up to 28 weeks.
Objective: To determine if acute treatment with aripiprazole (APZ) would be superior to treatment with placebo in reducing dysfunctional symptoms of elevated mood and/or irritability in symptomatic children and adolescents at familial high risk for bipolar disorder (BPD) whose mood episodes occur spontaneously. These are patients we have previously referred to as suffering from "cyclotaxia."
Methods: This was single-site, randomized, double-blind, placebo-controlled outpatient clinical trial in which youths aged 5-17 years who met diagnostic criteria for either cyclothymic disorder (CYC) or BPD not otherwise specified (BP-NOS) were randomly assigned to receive either APZ or placebo.
Background: Lithium is a benchmark treatment for bipolar disorder in adults. Definitive studies of lithium in pediatric bipolar I disorder (BP-I) are lacking.
Methods: This multicenter, randomized, double-blind, placebo-controlled study of pediatric participants (ages 7-17 years) with BP-I/manic or mixed episodes compared lithium (n = 53) versus placebo (n = 28) for up to 8 weeks.
Background: The developmental need to fit in may lead to higher alcohol and other drug use among socially anxious youths which exacerbates the drink/trouble cycle. In treatment, youths with social anxiety disorder (SAD) may avoid participating in therapeutic activities with risk of negative peer appraisal. Peer-helping is a low-intensity, social activity in the 12-step program associated with greater abstinence among treatment-seeking adults.
View Article and Find Full Text PDFObjectives: The Longitudinal Assessment of Manic Symptoms (LAMS) study was designed to investigate phenomenology and establish predictors of functional outcomes in children with elevated manic symptoms. The purpose of this series of analyses was to determine whether the participants demonstrated different trajectories of parent-reported manic and biphasic symptoms over the first 24 months of follow-up and to describe the clinical characteristics of the trajectories.
Methods: The 707 participants were initially aged 6-12 years and ascertained from outpatient clinics associated with the four university-affiliated LAMS sites.
Objectives: Controversy surrounds the diagnostic categorization of children with episodic moods that cause impairment, but do not meet DSM-IV criteria for bipolar I (BD-I) or bipolar II (BD-II) disorder. This study aimed to characterize the degree to which these children, who meet criteria for bipolar disorder not otherwise specified (BD-NOS), are similar to those with full syndromal BD, versus those with no bipolar spectrum diagnosis (no BSD).
Methods: Children aged 6-12 years were recruited from nine outpatient clinics, preferentially selected for higher scores on a 10-item screen for manic symptoms.

Objective: This study examined the long-term effectiveness of lithium for the treatment of pediatric bipolar disorder within the context of combination mood stabilizer therapy for refractory mania and pharmacological treatment of comorbid psychiatric conditions.
Methods: Outpatients, ages 7-17 years, meeting American Psychiatric Association, diagnostic and statistical manual of mental disorders, 4th ed. (DSM-IV) diagnostic criteria for bipolar disorder I (BP-I) (manic or mixed) who demonstrated at least a partial response to 8 weeks of open-label treatment with lithium (phase I) were eligible to receive open-label lithium for an additional 16 weeks (phase II).
Background: The primary purpose of this study was to explore whether age differences in the phenomenology of bipolar disorders from 4 to 17 years of age exist.
Methods: Outcome measures included questionnaires pertaining to mood symptoms, psychosocial functioning, and family history of psychiatric illness. Phenomenology was examined in two diagnostic groups: syndromal bipolar disorder (bipolar I or II) and subsyndromal bipolar disorder (bipolar disorder not otherwise specified or cyclothymia) and across six age cohorts: 4-6, 7-8, 9-10, 11-13, and 14-17 years.
Objective: To examine the proposed disruptive mood dysregulation disorder (DMDD) diagnosis in a child psychiatric outpatient population. Evaluation of DMDD included 4 domains: clinical phenomenology, delimitation from other diagnoses, longitudinal stability, and association with parental psychiatric disorders.
Method: Data were obtained from 706 children aged 6-12 years who participated in the Longitudinal Assessment of Manic Symptoms (LAMS) study (sample was accrued from November 2005 to November 2008).
Background: This study evaluates the long-term efficacy of aripiprazole compared to placebo in children with bipolar disorders.
Method: Outpatients aged 4 to 9 years meeting DSM-IV criteria for a bipolar disorder (I, II, not otherwise specified, cyclothymia) were eligible to receive up to 16 weeks of open-label treatment with aripiprazole (phase 1). Patients were randomized into the 72-week double-blind phase of the study once they met a priori response criteria for stabilization (phase 2).

Objective: The primary goal of this exploratory study was to obtain data that could lead to evidence-based dosing strategies for lithium in children and adolescents suffering from bipolar I disorder.
Methods: Outpatients aged 7-17 years meeting Diagnostic and Statistical Manual of Mental Disorders, 4th edition, diagnostic criteria for bipolar I disorder (manic or mixed) were eligible for 8 weeks of open label treatment with lithium in one of three dosing arms. In Arm I, participants began treatment at a dose of 300 mg of lithium twice daily.
Objective: The aim of the Longitudinal Assessment of Manic Symptoms (LAMS) study is to examine differences in psychiatric symptomatology, diagnoses, demographics, functioning, and psychotropic medication exposure in children with elevated symptoms of mania (ESM) compared to youth without ESM. This article describes the initial demographic information, diagnostic and symptom prevalence, and medication exposure for the LAMS cohort that will be followed longitudinally.
Method: Guardians of consecutively ascertained new outpatients 6 to 12 years of age presenting for treatment at one of 10 university-affiliated mental health centers were asked to complete the Parent General Behavior Inventory-10-Item Mania Scale (PGBI-10M).
Developmental disorders such as subaverage intelligence, pervasive developmental disorders, and genetic syndromes are frequently associated with comorbid attention-deficit/hyperactivity disorder (ADHD) or ADHD-like symptoms. While there are not pharmacological cures for these developmental disorders, coinciding ADHD and ADHD-like symptoms that contribute to difficulties in psychosocial functioning are frequently able to be addressed by pharmacotherapy. This article reviews what is known about the efficacy and tolerability of pharmacological interventions for the treatment of children and adolescents suffering from developmental disorders and comorbid ADHD/ADHD-like symptoms.

Children and adolescents who are the offspring of a bipolar parent and who first present with major depressive disorder (MDD) are at high risk for eventually developing bipolar disorder. In this report, the authors describe a group of 9 such high-risk children and adolescents with MDD, aged 7-16 years, who were randomized to receive treatment with either paroxetine monotherapy or combination paroxetine-divalproex sodium therapy. In the long-term management of depressive symptomatology in these patients, neither treatment appeared to be particularly effective.
