The rates of co-occurring behavioural addictions in treatment-seeking individuals with obsessive-compulsive disorder: a preliminary report.

To assess the rates of co-occurring putative 'behavioural addictions' in patients with obsessive-compulsive disorder (OCD). Twenty-three international centres specialising in the treatment of OCD were invited to participate in a survey of the rates of behavioural addictions and other relevant comorbidity within their samples. Sixteen of 23 (69.

Treatments used for obsessive-compulsive disorder-An international perspective.

Objective: The objective of this study was to characterise international trends in the use of psychotropic medication, psychological therapies, and novel therapies used to treat obsessive-compulsive disorder (OCD).

Methods: Researchers in the field of OCD were invited to contribute summary statistics on the characteristics of their samples. Consistency of summary statistics across countries was evaluated.

Prevalence of bullying in a pediatric sample of body dysmorphic disorder.

Little is known about etiological factors in Body dysmorphic disorder (BDD). Cognitive behavioral and diathesis-stress models have implicated teasing and bullying as significant early environmental stressful triggers. Due to these implications, this study aimed to assess the emergence of BDD in children during early development, and to see if bullying experiences played a role in its development.

Overvalued ideation in adolescents with obsessive-compulsive disorder.

In Obsessive Compulsive Disorder (OCD), overvalued ideas (OVI) are considered poor prognostic indicators in adults. To date, OVI has not been studied in an adolescent population with OCD, nor has it been examined in relation to obsessive-compulsive beliefs. To investigate the relationship between OVI and specific cognitions, fifty-five adolescents with OCD (35 male; 20 female; age range 13-17 years; M=14.

Status of body dysmorphic disorder in Argentina.

Although body dysmorphic disorder (BDD) has received recent attention, it remains misunderstood and under-studied. The Argentine population seeks out plastic surgery at a disproportionate rate and exhibits high rates of preoccupation with bodily dissatisfaction, yet BDD is unrecognized and research is limited. The current study describes the prevalence, quality of life, and presentation style of BDD in depressed adolescents, as depression is the most common symptom for which adolescents seek treatment in Argentina.

Regulation of m1 muscarinic receptors and nNOS mRNA levels by autoantibodies from schizophrenic patients.

In this paper we demonstrate that, circulating antibodies from schizophrenic patients interacting with cerebral M1 muscarinic acetylcholine receptors (M1 mAChRs), can act as an inducer of m1 mAChR-mRNA, and neuronal nitric oxide synthase (nNOS) mRNA gene expression of rat frontal cortex. The different signaling pathways involved in the autoantibody's actions, were characterized. As previously reported serum autoantibodies from schizophrenic patients reacted against neural cells surface inhibiting the binding of the specific mAChR radioligand to rat cerebral frontal cortex membrane.

Antibodies against astrocyte M1 and M2 muscarinic cholinoceptor from schizophrenic patients' sera.

We demonstrated the presence of circulating antibodies from schizophrenic patients able to interact with cultured astrocytes activating muscarinic acetylcholine receptors (mAChRs). Sera and purified IgG from 15 paranoid schizophrenic and 15 age-matched normal subjects were studied by indirect immunofluorescence (IFI), flow cytometry, dot blot, enzyme immunoassay (ELISA), and radioligand competition assays. Astrocyte membranes and/or a synthetic peptide, with identical amino acid sequence of human M(1) and M(2) mAChR, were used as antigens.

Antibodies against cerebral M1 cholinergic muscarinic receptor from schizophrenic patients: molecular interaction.

We demonstrated the presence of circulating Abs from schizophrenic patients able to interact with cerebral frontal cortex-activating muscarinic acetylcholine receptors (mAChR). Sera and purified IgG from 21 paranoid schizophrenic and 25 age-matched normal subjects were studied by indirect immunofluorescence, flow cytometry, immunoblotting, dot blot, ELISA, and radioligand competition assays. Rat cerebral frontal cortex membranes and/or a synthetic peptide, with an amino acid sequence identical with that of human M(1) mAChR, were used as Ags.
