SUMMARY Title: Cognitive-Behavioural Therapy of Obsessive-Compulsive Disorder Author: Veronika Nives Zoric Obsessive-Compulsive disorder is a severe and debilitating psychiatric disorder affecting more and more people worldwide. As the fourth most common psychiatric disorder, its history can be traced back to the 16th century. Although previously classified as an anxiety disorder in DSM-IV, it has recently been given its own chapter with related disorders in DSM-5. In ICD-10, OCD is grouped with neurotic, stress-related and somatoform disorders, and given the code F42. ICD-10 subdivides OCD into three types: predominantly obsessive type, predominantly compulsive type, and the most commonly found mixed type. Obsessions can be defined as repetitive and persistent thoughts or feelings that are viewed by the patient as intrusive and inappropriate and cause marked anxiety or distress. Typical obsessions include: fears of being contaminated by germs or poisons, fears of causing harm to oneself or others, and fears of committing some unacceptable action. Compulsions, on the other hand, are repetitive acts or behaviours that the patient deems necessary to

  • Tic Disorders
    No. 35 May 2012 Tic Disorders A tic is a problem in which a part of the body moves repeatedly, quickly, suddenly and uncontrollably. Tics can occur in any body part, such as the face, shoulders, hands or legs. They can be stopped voluntarily for brief periods. Sounds that are made involuntarily (such as throat clearing, sniffing) are called vocal tics. Most tics are mild and hardly noticeable. However, in some cases they are frequent and severe, and can affect many areas of a child's life. The most common tic disorder is called "transient tic disorder" and may affect up to 10 percent of children during the early school years. Teachers or others may notice the tics and wonder if the child is under stress or "nervous." Transient tics go away by themselves. Some may get worse with anxiety, tiredness, and some medications. Some tics do not go away. Tics which last one year or more are called "chronic tics." Chronic tics affect less than one percent of children and may be related to a special, more unusual tic disorder called Tourette's Disorder. Children with Tourette's Disorder have both body and vocal tics (throat clearing). Some tics disappear by early adulthood, and some continue. Children with Tourette's Disorder may also have problems with attention, and learning disabilities. They may act impulsively, and/or develop obsessions and compulsions. Sometimes people with Tourette's Disorder may blurt out obscene words, insult others, or make obscene gestures or movements. They cannot control these sounds and movements and should not be blamed for them.

These emotional fears can be focused on separating from parents, physical illness, performing poorly, or embarrassing themselves. Or they can be attached to specific things, like dogs or insects or bridges.” We hope that this will give you a greater understanding of anxiety disorders and the ways that parents and professionals can support children at home, in school, and in the community.

  • Tourette Syndrome and Tic Disorders
    Tourette Syndrome and Tic Disorders Presentation by Kiran Singh, PGY-3 UCI/CHOC Pediatrics Residency Program Case 1: Leslie ● 8 year old previously healthy female. At age 6, she started developing involuntary blinking and head jerking. These movements will sometimes recede for a couple of weeks but then reappear without any known triggers. She has a family history of generalized anxiety disorder in mom, OCD in dad. She is not on any medications currently. Otherwise, she is doing well in school, and has been told she has “above average intelligence. Mom does, however, report that she has “an anxious temperament.” What is her diagnosis? Case 2: Benjamin ● 11 year old with history of inattention and hyperactivity presenting with a history of throat clearing since age 10, with grimacing and shoulder shrugging. Mom is frustrated with his behavior, saying “first he wouldn’t stop disrupting class by clearing his throat loudly, which finally got better over the last few weeks, but now he’s starting to make grunting sounds!” Benjamin says he can’t control these actions, that he just has an urge to them and feels better after doing them. He otherwise is not on any medications. His brother has a history of ADHD. What is his diagnosis? Tic Disorders: DSM V diagnoses ● Tourette’s disorder: the presence of both motor and vocal tics for more than 1 year (Case 2: Benjamin) ● Persistent (chronic) motor or vocal tic disorder: single or multiple motor or vocal tics for more than 1 year, but not both motor and vocal (Case 1: Leslie) ● Provisional tic disorder

The series presents published volumes that comprehensively review neural receptors for a specific hormone or neurotransmitter by invited leading specialists. Particular attention is paid to in-depth studies of receptors’ role in health and neuropathological processes. Recent volumes in the series cover chemical, physical, modeling, biological, pharmacological, anatomical aspects and drug discovery regarding different receptors. All books in this series have, with a rigorous editing, a strong reference value and provide essential up-to-date resources for neuroscience researchers, lecturers, students and pharmaceutical research.

  • Pediatric Autoimmune Neuropsychiatric Disorder
    Research Pediatric Autoimmune Neuropsychiatric Disorder Associated with Streptococcal Infection (PANDAS): Clinical Manifestations, IVIG Treatment Outcomes, Results from a Cohort of Italian Patients Piero Pavone1, Raffaele Falsaperla1, Francesco Nicita2, Andreana Zecchini3, Chiara Battaglia1, Alberto Spalice 2, Lucia Iozzi3, Enrico Parano4, Giovanna Vitaliti1, Alberto Verrotti5, Vincenzo Belcastro6, Sung Yoon Cho7,†, Dong-Kyu Jin7, Salvatore Savasta3 Abstract Pediatric Autoimmune Neuropsychiatric Disorder associated with Streptococcal Infection (PANDAS) is characterized with main clinical features including obsessive-compulsive disorders and tics, acute-onset in prepubertal age, relapsing-remitting course, association with neurological abnormalities (mainly choreiform movements and motor hyperactivity), and temporal relationship with group A streptococcal infections. Thirty- four children with a serious- severe grade of PANDAS were enrolled in Italian Institutions with the aim to report clinical manifestations of the patients and their response to the intravenous immunoglobulin (IVIG) treatment. All patients were selected according to the Swedo‘s criteria and specific laboratory investigations as suggested by Chang for the PANS and treated with IVIG at the dosage of 2 g/kg/day for two consecutive days. At the onset, all patients presented with at least, one psychiatric manifestation including anxiety, emotional lability, bedwetting, enuresis, and phobia, and oppositional behavior including temper tantrums, personality changes, and deterioration in math skills and handwriting. At the laboratory investigations, positivity of pharyngeal swab for streptococcal infection in most of the patients and variable titers of anti-DNase B and ASO were found. In 29 patients reduction or disappearing of the motor symptoms were reached after 1 or 2 cycles of IVIG treatment, while in 5 patients the symptoms reappeared after the third cycle of IVIG.
