Quadro clínico do transtorno obsessivo-compulsivo

Obsessive-compulsive disorder is a very heterogeneous condition, not always easy to be identified. Obsessions are intrusive thoughts, impulses or images that cause anxiety or other emotional discomfort, whereas compulsions are repetitive behaviors or mental acts voluntarily performed to counterbalance or minimize the discomfort, or magically prevent any feared events. The most common symptoms are contamination, aggressive, somatic and sexual obsessions and washing, checking, repeating, counting and ordering compulsions. Patients usually have multiple symptoms simultaneously, which often change over time. Although the insight is typically preserved, it varies among patients and also fluctuates in the same patient in different ocasions. The main features are: exacerbated appraisal of risks, pathological doubts and incompleteness, as well as excessive sense of responsibility and guilt and thought/action fusion. As patients frequently feel ashamed of their symptoms, they can be reticent about them. Consequently, it usually takes time till they get adequate treatment.

Aspectos cognitivos do transtorno obsessivo-compulsivo

This paper describes the most important cognitive models for obsessive-compulsive disorder, i. e., the inference processes (thoughts and believes) underlying the patients'feelings and behaviors. The major models formulated in this area emphasize the following aspects: exacerbated perception of danger (risk evaluation), overimportance of intrusive thoughts, excessive sense of personal responsibility (blame for harm self and others), perfectionism, psychological fusion of thought and action, and illogical inference processes involving confusion between imagination and reality. The knowledge of cognitive aspects brings new perspectives for the psychological treatment of this disorder.

Pulpal and periodontal reactions of immature permanent teeth in the dog to intrusive trauma.

Pulpal and periodontal tissues of immature incisors of 10 dogs were radiographically and histopathologically evaluated immediately, 7, 15, 30 and 60 days after experimental intrusion induced by mechanical blows. Forty upper central and mesial lateral incisors showing incomplete root formation on radiographs were submitted to intrusive force. After the observation periods, the dogs were killed, two at a time. The hemi-maxilas were removed and processed for histopathologic examination. The traumatized teeth showed accelerated apical formation with reduced radicular length. Pulpal vitality was maintained and the subjacent tissues did not present irreversible changes. All traumatized teeth re-erupted spontaneously.
