Hyperthyroidism related to McCune-Albright syndrome: report of two cases and review of the literature
INTRODUCTION: McCune-Albright syndrome is a sporadic disease clinicaly characterized by polyostotic fibrous dysplasia, café-au-lait cutaneous spots and hyperfunctional endocrinopathies, such as precocious puberty, hyperthyroidism, acromegaly and others. The biologic physiopathology of the disease is based on an activating mutation of the gene for the Gs protein which mediates the activation of adenyl cyclase and subsequent gland autonomous secretion. The thyroid gland is usually involved in this disease, being hyperthyroidism the second most common endocrinopathy seen after precocious puberty. OBJECTIVE: Revision of the literature since 1937 to 1997, adding our casuistic and discussing the adequate treatment for the hyperthyroidism in the syndrome. RESULTS: Among 85 cases identified with the syndrome, hyperthyroidism treatment was described in 26 of them. Fifteen were submitted to surgery (total thyroidectomy), 6 were submitted to iodotherapy and 5 were treated with antithyroid drugs (ATD - propylthiouracil, carbimazole or methimazole). In some cases, treatment association was done. CONCLUSION: McCune-Albright syndrome is a rare disease, combining polyostotic fibrous dysplasia, café-au-lait cutaneous spots and hyperfunctional endocrinopathies. Cases with hyperthyroidism are treated iniatially clinically, but definitive ablation with surgery or radioiodine treatment is the most indicated option.INTRODUÇÃO: A síndrome de McCune Albright é uma doença rara, clinicamente definida pela combinação de displasia fibrosa poliostótica, manchas café-com-leite e endocrinopatias com hiperfunção, como puberdade precoce, hipertireoidismo, acromegalia e outras. A fisiopatologia biomolecular baseia-se em uma mutação ativadora do gene para a subunidade alfa da proteína de membrana Gs, que estimula a produção intracelular de AMPc, conferindo secreção autônoma à glândula em particular. A glândula tireóide é freqüentemente envolvida nesta doença, sendo o hipertireoidismo a segunda endocrinopatia mais comum após a puberdade precoce. OBJETIVO: Realizar uma revisão da literatura no período de 1937 a 1997, incluindo nossa casuística, e discutir o tratamento utilizado para o hipertireoidismo nesta síndrome. RESULTADOS: Do total de 85 casos, em 26 com hipertireoidismo se descreve o tipo de tratamento utilizado. Entre esses, 15 foram submetidos à cirurgia (tireoidectomia total), seis foram submetidos à iodoterapia e cinco foram submetidos a tratamento com drogas antitireoidianas (DAT - propiltiuracil, carbimazol ou metimazol), pois em alguns houve associação dos tratamentos citados anteriormente. CONCLUSÃO: A síndrome de McCune-Albright é uma doença rara, que inclui displasia fibrosa poliostótica, manchas café-com-leite e endocrinopatias com hiperfunção. Os casos acompanhados com hipertireoidismo são inicialmente tratados clinicamente com DAT, porém a ablação cirúrgica ou com radioiodoterapia é a opção definitiva mais indicada.Universidade Federal de São Paulo (UNIFESP) Departamento de Otorrinolaringologia e Cirurgia de Cabeça e PescoçoUNIFESP, Depto. de Otorrinolaringologia e Cirurgia de Cabeça e PescoçoSciEL
Exploratory analysis of obsessive compulsive symptom dimensions in children and adolescents: a Prospective follow-up study
BACKGROUND: Recent statistical approaches based on factor analysis of obsessive compulsive (OC) symptoms in adult patients have identified dimensions that seem more effective in symptom-based taxonomies and appear to be more stable over time. Although a phenotypic continuum from childhood to adulthood has been hypothesized, no factor analytic studies have been performed in juvenile patients, and the stability of OC dimensions in children and adolescents has not been assessed. METHODS: This study was designed to perform an exploratory factor analysis of OC symptoms in a sample of children and adolescents with OC disorder (OCD) and to investigate the course of factors over time (mean follow-up period: four years). RESULTS: We report for the first time that four symptom dimensions, remarkably similar to those previously described in adults, underlined the heterogeneity of OC symptoms in children and adolescents. Moreover, after follow-up, the symptom dimensions identified remained essentially unmodified. The changes observed concerned the intensity of dimensions rather than shifts from one dimension to another. CONCLUSION: These findings reinforce the hypothesis of a phenotypic continuum of OC symptoms from childhood to adulthood. They also strengthen the interest for investigating the clinical, neurobiological and genetic heterogeneity of OCD using a dimension-based approach
Knowledge and competency standards for specialized cognitive behavior therapy for adult obsessive-compulsive disorder
Obsessive-Compulsive Disorder (OCD) is a leading cause of disability world-wide (World Health Organization, 2008). Treatment of OCD is a specialized field whose aim is recovery from illness for as many patients as possible. The evidence-based psychotherapeutic treatment for OCD is specialized cognitive behavior therapy (CBT, NICE, 2005, Koran and Simpson, 2013). However, these treatments are not accessible to many sufferers around the world. Currently available guidelines for care are deemed to be essential but insufficient because of highly variable clinician knowledge and competencies specific to OCD. The phase two mandate of the 14 nation International OCD Accreditation Task Force (ATF) created by the Canadian Institute for Obsessive Compulsive Disorders is development of knowledge and competency standards for specialized treatments for OCD through the lifespan deemed by experts to be foundational to transformative change in this field. This paper presents knowledge and competency standards for specialized CBT for adult OCD developed to inform, advance, and offer a model for clinical practice and training for OCD. During upcoming ATF phases three and four criteria and processes for training in specialized treatments for OCD through the lifespan for certification (individuals) and accreditation (sites) will be developed based on the ATF standards
When Too Much Is Not Enough: Obsessive-Compulsive Disorder as a Pathology of Stopping, Rather than Starting
Background: In obsessive-compulsive disorder (OCD), individuals feel compelled to repeatedly perform security-related behaviors, even though these behaviours seem excessive and unwarranted to them. The present research investigated two alternative ways of explaining such behavior: (1) a dysfunction of activation—a starting problem—in which the level of excitation in response to stimuli suggesting potential danger is abnormally strong; versus (2) a dysfunction of termination— a stopping problem—in which the satiety-like process for shutting down security-related thoughts and actions is abnormally weak. Method: In two experiments, 70 patients with OCD (57 with washing compulsions, 13 with checking compulsions) and 72 controls were exposed to contamination cues—immersing a hand in wet diapers —and later allowed to wash their hands, first limited to 30 s and then for as long as desired. The intensity of activation of security motivation was measured objectively by change in respiratory sinus arrythmia. Subjective ratings (e.g., contamination) and behavioral measures (e.g., duration of hand washing) were also collected. Results: Compared to controls, OCD patients with washing compulsions did not differ significantly in their levels of initial activation to the threat of contamination; however, they were significantly less able to reduce this activation by engaging in the corrective behavior of hand-washing. Further, the deactivating effect of hand-washing in OCD patients with checkin

Manifestation of incompleteness in obsessive-compulsive disorder (OCD) as reduced functionality and extended activity beyond task completion
Copyright 2011 Zor et al.

For this, we had to document the behavioral manifestation of incompleteness in compulsive rituals, predicting that an exaggerated focus on acts that are appropriate for the task will support the hypothesis on heightened responsibility/perfectionism. In contrast, activity past the expected terminal act for the motor task would support the "stop signal deficiency" hypothesis. Methodology and Principal Findings: We employed video-telemetry to analyze 39 motor OCD rituals and compared each with a similar task performed by a non-OCD individual, in order to objectively and explicitly determine the functional end of the activity. We found that 75% of OCD rituals comprised a "tail ," which is a section that follows the functional end of the task that the patients ascribed to their activity. The other 25% tailless rituals comprised a relatively high number and higher rate of repetition of non-functional acts. Thus, in rituals with tail, incompleteness was manifested by the mere presence of the tail whereas in tailless rituals, incompleteness was manifested by the reduced functionality of the task due to an inflated execution and repetition of non-functional acts. Conclusions: The prevalence of activity after the functional end ("tail") and the elevated non-functionality in OCD motor rituals support the "lack of stop signal" theories as the underlying mechanism in OCD. Furthermore, the presence and content of the tail might have a therapeutic potential in cognitive-behavior therapy.Peer reviewe
Looking for Outcomes: The Experience of Control and Sense of Agency in Obsessive-compulsive Behaviors
Obsessive-Compulsive Disorder (OCD) can be conceptualized as a disturbance of control over one’s thoughts and actions, and through them, over external events. Classically, there are two general approaches to the explanation of OCD symptoms: a cognitive account that emphasizes the important role played by dysfunctional beliefs in the exaggerated appraisals of negative outcomes (i.e., harm avoidance) and a sensory phenomena account that highlights the role of impaired action monitoring in inconsistent feelings of dissatisfaction with actual outcomes (i.e., incompleteness). In this chapter, we review the phenomenology of these two OCD manifestations in light of the sense of agency framework. We argue that harm avoidance and incompleteness should be construed as distinct forms of defective outcome processing, leading to distinct impairments of the experience of action
