A method of closed irrigation has been devised to treat infections in the hand. After adequate débridement, two tubes are placed in the infected area, an inlet tube and an outlet tube. For a small infection, one tube serves both purposes. The wound is closed completely. Irrigation with saline and antibiotic solution is continued for 1 week, extended up to 3 weeks in cases of severe infection. This method has been applied in 31 cases including pyogenic tenosynovitis, tuberculous tenosynovitis, pyogenic arthritis, osteomyelitis, bite injury, crush injury and amputation stump infection. Infection healed primarily in 29 cases. Further surgery was needed in two cases which healed finally.

Many methods have been clinically applied for the occlusal analysis in the intercuspal position. However, none of these methods are quantitative. This study described the new software version of the T-Scan system to record and analyze occlusal contact balance in the anterior-posterior and right-left directions. Six time moment statistics and five force moment statistics were calculated in the midsagittal and the incisal axes of the occlusal plane. In the present study, informed consent was obtained from 60 subjects with natural dentitions and from two patients with craniomandibular disorders. In normal subjects, the time moments and the force moments of occlusal contacts were symmetrical about the midsagittal axis of occlusal plane. The location of the center of effort for the antero-posterior occlusal contacts, which was measured from the incisal axis of occlusal plane, was also in the first molar region. However, any of the above mentioned statistics was abnormal in the patients with craniomandibular disorders.
