Patients with unilateral posterior crossbite often show reverse sequential jaw movement patterns on the frontal view during mastication on the crossbite side. Recent studies show that such patients are prone to suffer from temporomandibular joint (TMJ) disc displacement, particularly the lateral portion. The purpose of this study was to examine the movement(More)
Statistical studies on anorexia nervosa in Japan were carried out by our research group. Questionnaires were sent to physicians at 1,030 representative institutions throughout Japan and data were collected from 315 institutions. The total number of patients with anorexia nervosa in 1981 was 940 outpatients and 372 inpatients. The number of patients in 1981(More)
BACKGROUND The aim of this study was to investigate the clinical features of psychosomatic disorders in Japan. METHODS A total of 1,432 outpatients (515 males and 917 females; 9-95 years of age, mean age 36) attending a psychosomatic clinic for the first time were assessed by the DSM-III-R or DSM-IV semistructured interview. RESULTS Major ICD-10(More)
Which is more important, hereditary factors or psychological environment factors, in the etiology of anorexia nervosa? The question is studied by considering 7 cases of anorexia nervosa in monozygotic twins of the authors' own practice. In 5 of 7 cases, only 1 of a set of twins was found to be suffering from anorexia nervosa. On the other hand, in 2 of 7(More)
MicroRNAs (miRNAs) are small RNA molecules of 21-25 nucleotides that regulate cell behavior through inhibition of translation from mRNA to protein, promotion of mRNA degradation and control of gene transcription. In this study, we investigated the miRNA expression signatures of cell cultures undergoing osteoblastic and osteocytic differentiation from(More)
Many patients with trigeminal neuropathies suffer severe chronic pain which is inadequately alleviated with centrally-acting drugs. These drugs also possess severe side effects making compliance difficult. One strategy is to develop new treatments without central side effects by targeting peripheral sensory neurons, since sensory neuron excitability and(More)
Because many patients present themselves for treatment with both craniofacial and craniocervical pain, 2 questions arise: (1) What are the sensory and motor consequences of dysfunction in either of these areas on the other? (2) Do craniofacial and craniocervical pain have a similar cause? These questions formed the impetus for this review article. The(More)
Parental bonding patterns were studied in 52 female Japanese eating disorder outpatients with and without histories of sexual or physical abuse and with dissociation. Instruments included the Parental Bonding Instrument (PBI), the Dissociative Experiences Scale (DES) and the Dissociative Disorders Interview Schedule (DDIS). Those with physical abuse(More)
Despite a high prevalence of chronic muscle pain disorders such as fibromyalgia and regional myofascial pain, there is still limited knowledge about the factors that initiate and perpetuate these pain states. Although there are also likely to be downstream neuropathic changes in the central nervous system and spinal cord that sustain and exacerbate the pain(More)
This study examined the effects of electroencephalographic- (EEG-) driven photic stimulation on a case of depressive disorder, as measured by a psychometric test of mood states, EEG parameters, and several autonomic indices. The EEG-driven photic stimulation enhances the alpha rhythm of brain waves using photic signals, the brightness of which is modulated(More)
