Rheumatoid arthritis (RA) is often associated with deformities of the feet, and foot pain often arises in the talonavicular joint of patients with RA. The object of this study was to assess the relationship between magnetic resonance imaging (MRI) findings of the talonavicular joint and walking ability. The subjects were 35 RA patients (10 feet in 5 males and 56 feet in 30 females) aged 34-87 years (mean: 70 years +/- 12.1), with a disease duration from 1-54 years (mean: 14 years +/- 12.1). MRI findings were classified as follows: Grade 1, almost normal; Grade 2, early articular destruction; Grade 3, moderate articular destruction; Grade 4, severe articular destruction; and Grade 5, bony ankylosis dislocation. Walking ability was classified into one of 9 categories ranging from normal gait to bedridden status according to the system of Fujibayashi. As the grade of MRI images became higher the walking ability decreased, and these parameters showed a correlation by Spearman's rank correlation coefficient analysis (P = 0.003). Thus, in the present cohort group of patients with RA, the deterioration of walking ability increased with the severity of destruction of the talonavicular joint.

Thoracic Outlet Syndrome and dysfunction of the temporomandibular joint(<SPECIAL ISSUE>Temporomandibular disorder and its relating medicine)

Senda Masuo, Hamada Masanori, Katayama Yoshimi, Tsukiyama Naosi

The Journal of Japanese Society of Stomatognathic Function 10 ( 1 ) 7 - 10 2003.12

Language：Japanese Publisher：Japanese Society of Stomatognathic Function

Chief complaints of Patients with thoracic outlet syndrome (TOS) are pain, numbness, and dullness at their neck, shoulder or upper extremity. Such symptoms result from compression or traction of the neurovascular bundle through the thoracic outlet. The entrapment of the neurovascular bundle may be caused by a cervical rib, by hypertrophy or spasm of the scalenus anterior, by abnormal droop of the shoulder girdle, by spasm of the scalenus medius secondary trauma or abnormal posture, by anomalies of the first rib, by abnormal tension of the pectoralis minor. In tempromandibular disorder (TMD), patients often compliant neck stiffness. The neck muscles of the patients with TMD, for example scalenus anterior and scalenus medius, become so stiff that the thoracic outlet may be narrow. The patients with TMD easily suffer from TOS at the same time. We have to be able to diagnose TOS when the patients with TMD complain of pain, numbness, and dullness at their neck, shoulder or upper extremity. In order to diagnose TOS, useful clinical tests, Adson test, Wright test, Eden test, Alien test, Morley test, and Roos test are explained. And new methods to diagnose TOS, somatosensory evoked potential (SSEP), F-wave, brachial plexus neurography, and MRI are introduced. Conservative treatments of TOS are described, for example muscle exercise around the neck and shoulder, stretching, relaxation, and arthrokinetic approach (AKA). Surgical methods are rare to treat TOS, and the most effective operation is decompression of the neurovascular bundle by resection of the first rib and anomalous structures.

Lucifer Yellow slows voltage-gated Na+ current inactivation in a light-dependent manner in mice. International journal

Yoko Higure, Yoshimi Katayama, Keita Takeuchi, Yoshitaka Ohtubo, Kiyonori Yoshii

The Journal of physiology 550 ( Pt 1 ) 159 - 67 2003.7

Language：English Publishing type：Research paper (scientific journal)

Lucifer Yellow CH (LY), a membrane-impermeant fluorescent dye, has been used in electro-physiological studies to visualize cell morphology, with little concern about its pharmacological effects. We investigated its effects on TTX-sensitive voltage-gated Na+ channels in mouse taste bud cells and hippocampal neurons under voltage-damp conditions. LY applied inside cells irreversibly slowed the inactivation of Na+ currents upon exposure to light of usual intensities. The inactivation time constant of Na+ currents elicited by a depolarization to -15 mV was increased by fourfold after a 5 min exposure to halogen light of 3200 Ix at source (3200 Ix light), and sevenfold after a 1-min exposure to 12,000 Ix light. A fraction of the Na+ current became non-inactivating following the exposure. The non-inactivating current was approximately 20 % of the peak total Na+ current after a 5 min exposure to 3200 Ix light, and approximately 30 % after a 1 min exposure to 12,000 Ix light. Light-exposed LY shifted slightly the current-voltage relationship of the peak Na+ current and of the steady-state inactivation curve, in the depolarizing direction. A similar light-dependent decrease in kinetics occurred in whole-cell Na+ currents of cultured mouse hippocampal neurones. Single-channel recordings showed that exposure to 6500 Ix light for 3 min increased the mean open time of Na+channels from 1.4 ms to 2.4 ms without changing the elementary conductance. The pre-incubation of taste bud cells with 1 mM dithiothreitoL a scavenger of radical species, blocked these LY effects. These results suggest that light-exposed LY yields radical species that modify Na+ channels.
