Latent inhibition (LI) consists of retardation in conditioning to a stimulus as a consequence of its prior non-reinforced pre-exposure. In view of findings that LI is disrupted in acute schizophrenic patients and evidence from animal experiments pointing to the involvement of the mesolimbic dopamine (DA) system in this phenomenon, the present study(More)
OBJECTIVE The aim of this study was to evaluate the effectiveness of decompression as the initial treatment for odontogenic cysts. STUDY DESIGN Pre- and postdecompression panoramic radiographs of 57 patients treated for 73 odontogenic cysts were reviewed for reduction parameters. Findings were evaluated against time of decompression and clinical and(More)
To evaluate disease dynamics, treatment results, and frequency of malignant transformation. Ten-year single center retrospective study. The study included 171 patients, 28-99 years old. Follow-up was 1-16 years. 49.5% exhibited changes in clinical presentation, with 19% yearly increase of probability for type shift. Index of extent (number of oral(More)
The effects of bilateral electrolytic lesions of the "shell" subterritory of the nucleus accumbens in the rat were examined on 2 tasks known to be sensitive to hippocampal damage. Experiment 1 tested the effects of shell lesion on delayed non-matching-to-sample (DNMS) task in a T-maze. The maze was rotated 180 degrees after the end of acquisition.(More)
Continual refinements of the surgical technique and instrumentation for the intraoral vertical ramus osteotomy have made it a preferred procedure for mandibular setback, especially in asymmetrical cases. However, there may be intraoperative difficulty in lateral positioning of the proximal segment, which is frequently trapped medially. Three techniques for(More)
PURPOSE To investigate the correlation between clinical characteristics, radiologic features, treatment modalities, and treatment outcome of glandular odontogenic cyst, and to suggest a treatment protocol based on these results. PATIENTS AND METHODS The study included a total of 56 cases, 49 from the literature and 7 new cases. Demographic data,(More)
OBJECTIVES Clinico-pathological evaluation of bisphosphonate (BP)-related osteonecrosis of jaws, comparison between oral (PO) and intravenous (IV) BPs and histomorphometric analysis of associated actinomyces. STUDY DESIGN Retrospective clinical and histomorphometric analysis. Data on background, clinical, treatment and follow-up were analyzed. Actinomyces(More)
OBJECTIVE To review our 17-year clinical experience with delayed oroantral fistula repair by palatal rotation-advancement flap, and to report its advantages, disadvantages, and complications. STUDY DESIGN The records of 63 patients with late oroantral fistula treated by palatal rotation-advancement flap from 1984 to 2002 were reviewed. Eleven had(More)
Intraoral facial and laryngeal features of tumoral calcinosis are reviewed in six patients of Jewish-Yemenite descent. Extraoral features included calcified masses, erythematous patches, and angular cheilitis. Oral soft tissue findings included papillary hyperplasia of the lip vermilion and velvety-red macules on the tongue, palate, and buccal mucosa.(More)
