Upper extremity venous thrombosis. Case report and literature review.

Upper extremity venous thrombosis is a clinical entity with numerous etiologic factors. Only 2% of all cases of deep venous thrombosis involve the upper extremity, and the incidence of pulmonary embolism related to thrombosis in this location is approximately 12%. Primary or "effort" thrombosis of the upper limb is related to the inherent anatomical structure of the thoracic outlet and axillary region. Secondary thrombosis may have such diverse origins as trauma, infection, congestive heart failure, central venous catheters, neoplasms, septic phlebitis, intravenous drug use, and hypercoagulable states. Patients present with peripheral edema and prominent superficial veins, and neurologic symptoms (pain and paresthesias) are usually present as well. Clinical diagnosis is confirmed by venography or sonography. Treatment regimens include conservative measures, thrombolysis with fibrinolytic agents, and surgical correction of indicated thoracic outlet and axillary structures. We present an unusual case in which upper extremity venous thrombosis in a young healthy female athlete was associated with the presence of cervical ribs. The patient was successfully treated with focal thrombolysis and surgical resection of her ipsilateral cervical rib.

Erosive arthritis of the temporomandibular joint caused by Teflon-Proplast implants: plain film features.

Six patients had osseous destructive changes of the temporomandibular joint after placement of Teflon-Proplast implants for treatment of internal derangements. The implants were surgically removed from all six joints, and foreign-body reactions were found to account for the radiographic appearance. The plain film radiographic features included single or multiple osseous erosions of the mandibular condyle in all cases and the temporal bone of the glenoid fossa in two cases. Some erosions were poorly defined, whereas others were well defined, either with or without sclerotic margins. Radiologists must be aware of this possible complication of alloplastic temporomandibular joint implants in order to suggest the diagnosis in the appropriate clinical setting.

Postanesthetic temporomandibular joint dysfunction.

Internal derangements, myofascial pain dysfunction, and chronic dislocation of the temporomandibular joint (TMJ) are three common sequelae resulting from mandibular trauma. Etiologic factors include prolonged dental and otolaryngologic procedures, and intraoperative use of the laryngoscope and bronchoscope. Three cases are reported to document postanesthetic TMJ dysfunction arising from normal preoperative joints. Four types of TMJ dysfunction are discussed: anterior meniscus dislocation with reduction, anterior meniscus dislocation without reduction, dislocation/subluxation of the mandibular condyle, and myofascial pain dysfunction syndrome. Preoperative screening of mandibular function is recommended in identifying patients as either normal or having potential TMJ dysfunction. Failure to recognize postoperative TMJ dysfunction can lead to long-term symptoms that are difficult to alleviate. Litigation is a common sequel in these cases.
