BACKGROUND Pain drawings have frequently been used for documentation of pain and a convenient diagnosis tool. Pain drawings were found to be associated with psychological states in chronic patients with low back pain. Few researchers have investigated pain drawings except in low back pain. The aim of this study was to investigate the pain, pain drawings,(More)
PURPOSE Apparent organic abnormalities are sometimes not identified among patients suffering from chronic pain in the craniocervical region. In some cases, parafunctional activities (PAs) are recognized. PAs are nonfunctional oromandibular activities that include jaw clenching and bruxism, but are considered as factors that contribute to craniomandibular(More)
— A chaotic map has sensitivity to changes in the initial conditions and parameters, and a long-term forecast becomes impossible by iterating a chaotic map. These features look similar to the features of cryptology. For this reason, it is effective to use chaotic maps for cryptosystems. In this research, we investigate features of the modified cut map when(More)
In this paper, we propose a new FDTD (Finite-Difference Time-Domain) method using the alternating-direction explicit (ADE) method for the efficient electromagnetic field simulation. Furthermore, the modified PML (Perfectly Matched Layer) absorbing boundary condition, which is applicable to the proposed new method, is introduced. Finally, The efficiency of(More)
We report on the use of pulsed radiofrequency (RF) within the plexus for the management of intractable pain in three patients with metastatic or invasive plexopathy. The patients were a 38-year-old woman with a history of breast cancer 6 years earlier whose computed tomography (CT) scans revealed a mass lesion at the infraclavicular part of the right(More)
There are patients who suffer from persistent dentoalveolar pain disorder (PDAP) which is a pain of the teeth, either dentoalveolar pain or nonodontogenic toothache, and its cause has not yet been identified. An effective intervention for PDAP has not yet been established. Interventions for patients with PDAP are generally pharmacological treatments such as(More)
Celiac plexus block (CPB) can be used for treating intra-abdominal visceral pain syndromes. The celiac plexus is the largest plexus of the sympathetic nervous system. Several nerve blocks have a marked effect on autonomic nervous activity. Furthermore, stellate ganglion block changes cardiac autonomic nervous activity. Thus, CPB could influence the(More)
Background. Two prophylactic papillomavirus (HPV) vaccines have been available for primary prevention of cervical cancer. Although serious adverse effects (AE) were rare, more than 230 women have been suffering from severe AEs such as persistent pain and headache in Japan. Our research group started to treat adolescent females suffering from the AEs.(More)
