The effect of arthroscopic surgery on mandibular range of motion.

Limited range of motion of the mandible secondary to intra-articular problems has become an accepted indication for temporomandibular joint (TMJ) arthroscopy. The authors have looked at 297 patients over a 2 1/2 year follow-up period. The patients were subdivided by their initial opening measurement (10-20 mm or 20-30 mm). The post-operative improvement of these patients was then evaluated. Furthermore, multiple variables were used to look at the effect of surgical procedures, diagnosis and other associated clinical findings on outcome. In conclusion, the authors found that the range of motion significantly improved to a close to normal opening in almost all patient groupings. This finding was unrelated to a variety of variables and supports the hypothesis that TMJ arthroscopic surgery has a definite role in treating restricted range of motion secondary to intra-articular pathology.

Immunological evaluation of patients with invasive carcinoma of the gallbladder.

Forty-three patients with invasive adenocarcinoma of the gallbladder were postoperatively studied in order to determine their general immunological status as well as the local immunohistological reaction to the tumor. At the end of the follow-up, they formed two groups: 19 living patients (group GL) and 24 dead patients (group GD). As a control group (GC), 21 patients with cholecystectomy or cholelithiasis and without carcinoma were simultaneously evaluated. In GL, most of the tumors were limited to the gallbladder wall, and in GD, most of the tumors were already disseminated at the time of diagnosis. GD presented a lower percentage of peripheral blood B lymphocytes, as compared to GL and GC cases. Skin tests of delayed hypersensitivity were significantly more reactive in GL cases than in GD cases, and less reactive in GD than in GC cases. The immunohistological evaluation of the gallbladder yielded a lower B lymphocyte infiltration in GD tumors than in the control cases. GL cases showed a higher intratumoral lymphocytic and mononuclear cell infiltration than GD cases. Although the clinical stage was higher in GD than in GL cases, there were also significant differences in the local immune response and the general immunological status. Patients with invasive gallbladder adenocarcinoma showing longer postoperative survival revealed normal or increased local and general immunological reactions, whereas patients with disseminated tumors showed an important humoral and cellular secondary immunodeficiency.

Special considerations in orofacial pain.

A pathologic dental condition is by far the most common cause of orofacial pain. There are, however, certain patients who possess and exhibit myriad signs and symptoms that mimic pathologic dental conditions but do not have a dental cause. These patients pose a diagnostic dilemma for the dental practitioner. Unfortunately, there are many documented cases of misdiagnosis and mismanagement in patients with deafferentiation pain, neuropathic pain, trigeminal neuralgia, and temporal arteritis. These orofacial pain disorders warrant special consideration for the dental practitioner and are reviewed in this article.
