Ecstasy [3,4-methylenedioxymethamphetamine (MDMA)] was shown to prolong the action of L-3,4-dihydroxyphenylalanine (L-DOPA) while suppressing dyskinesia in a single patient with Parkinson's disease (PD). The clinical basis of this effect of MDMA is unknown but may relate to its actions on either dopaminergic or serotoninergic systems in brain. In normal, drug-naive common marmosets, MDMA admini...

OBJECTIVE To determine the prevalence of tardive dyskinesia among psychiatric in-patients. DESIGN A cross-sectional survey. SETTING Mathari Hospital, Nairobi, the main psychiatric referral hospital in Kenya. SUBJECTS Two hundred and two randomly selected in-patients seen in the hospital between January and April 2000. RESULTS The prevalence of tardive dyskinesia was 11.9%. Neither the p...

Headache associated with cervical lesions is called cervicogenic headache and involves the occiput but not the orofacial region. However, patients occasionally present with orofacial pain accompanied by neck symptoms. This study investigates whether orofacial pain can originate from the neck and whether cervical plexus block can help in diagnosis. We enrolled eight patients suffering from chron...

BACKGROUND Orofacial symptoms are common in Parkinson's disease (PD) both as initial manifestations and late markers of disease complications. We aimed to investigate the evolution of orofacial manifestations and their prognostic value throughout PD progression. METHODS Data was obtained from "Jönköping Parkinson Registry" database on routine care visits of 314 people with idiopathic PD in so...

There is a growing medical and public concern about neuroleptic-induced persistent tardive dyskinesia. The clinician faces a difficult dilemma because there are no effective substitutes for neuroleptics in the treatment of a majority of schizophrenic patients. In dealing with this dilemma, the physician should 1) periodically assess indications for neuroleptics in each patient, 2) use the lowes...

Tardive dyskinesia is one of the most significant side effects of antipsychotic medications. Antipsychotic treated schizophrenia patients with diabetes mellitus are more likely to develop tardive dyskinesia than those without diabetes. Clozapine is probably best supported for management of tardive dyskinesia. But clozapine has been strongly linked to hyperglycaemia and impaired glucose toleranc...

A new device and automated measurement technology known as OroSTIFF is described to characterize non-participatory perioral stiffness in healthy adults for eventual application to patients with orofacial movement disorders associated with neuromotor disease, traumatic injury, or congenital clefts of the upper lip. Previous studies of perioral biomechanics required head stabilization for extende...

The pharmacology of synthetic organoselenium compounds indicates that they can be used as antioxidants, enzyme inhibitors, neuroprotectors, anti-tumor and anti-infectious agents, and immunomodulators. In this review, we focus on the effects of diphenyl diselenide (DPDS) in various biological model organisms. DPDS possesses antioxidant activity, confirmed in several in vitro and in vivo systems,...

UNLABELLED In 2012, the recognition of the specialty of Temporomandibular Disorders and Orofacial Pain completed ten years. Given this scenario, it is extremely important to track the current situation of this field of knowledge in Brazil, specifically in the area of research and training. We hope to discuss the importance of the recognition of this specialty and the inclusion of these subjects...

Orofacial granulomatosis is a rare chronic inflammatory disorder characterized by persistent or recurrent soft tissue swellings, oral ulceration, and other orofacial features in the absence of an identifiable granulomatous disease. We report a case of a 61-year-old woman with recurrent ulcerations and swellings in her oral mucosa. She was diagnosed as orofacial granulomatosis based upon clinico...
