1/511. Lumbar intraspinal synovial cysts of different etiologies: diagnosis by CT and MR imaging.

    Intraspinal synovial cysts arises from a facet joint and may cause radicular symptoms due to nerve root compression. In the present study, three surgically and histologically proved cases of synovial cyst of the lumbar spine with different etiology are described. The purpose of this report is to illustrate the imaging features of various etiologies of intraspinal synovial cysts allowing a correct preoperative diagnosis. review of the literature enables us to say that to our knowledge, there is no reported article collecting the imaging findings of intraspinal synovial cysts with different etiologies. Only single cases with rheumatoid arthritic or traumatic origin have been reported to date. We believe that computed tomography and particularly magnetic resonance imaging are the methods of choice which provide the most valuable diagnostic information. ( info)

2/511. Anteroposterior atlantoaxial subluxation in cervical spine osteoarthritis: case reports and review of the literature.

    Nontraumatic anteroposterior atlantoaxial subluxation (AAS) has been described in several rheumatic or inherited disorders, especially rheumatoid arthritis and to a lesser extent the inflammatory spondyloarthropathies. We describe AAS secondary to osteoarthritis (OA) of the cervical spine in a 76-year-old man and a 73-year-old woman with severe cervical OA, symptomatic C1-C2 facet joints, and signs of generalized OA. Only 6 similar cases exist in the literature. OA should be added to the causes of AAS, and conversely AAS should be assessed in cases with severe OA of the upper cervical spine. ( info)

3/511. Rapid tibial polyethylene failure in porous-coated anatomic total knees as a cause of clinical failure.

    Among 52 patients with porous-coated anatomic total knee arthroplasties, three (6%) underwent revision surgery because of failure of the tibial polyethylene at two years and three months, four years and three months, and four years and nine months after surgery. Thinning of the tibial polyethylene may have contributed to the failure in one patient. Heat pressing fabrication and the articular geometry possibly played a role in the development of failure in all three patients. Surgical latitude of the prosthetic design was considered to be too narrow to be applied to knee joints with severe deformity, for which knee prostheses with more intrinsic stability might be appropriate.

4/511. Incomplete nondisplaced tibial osteotomy for treatment of osteoarthritic knee pain.

    Intraosseous venous hypertension is considered a significant factor in the production of knee pain secondary to degenerative arthrosis, thus vascular decompression by means of tibial osteotomy is a rational option for treatment of selected patients. A preliminary report is presented of six patients with symptoms of primary or secondary degenerative arthrosis who were treated by incomplete nondisplaced proximal tibial osteotomy with good or excellent results. These patients were refractory to nonoperative treatment and were not deemed suitable candidates for angulated osteotomy, arthroscopic surgery alone, or total knee arthroplasty. patients ranged in age from 36 to 61 years (mean age: 47 years). Follow-up ranged from .8 to 6.7 years (mean: 3.1 years). The subjects were studied postoperatively by interview, physical examination, radiographs, and bone scans. Results were assessed using the knee rating system of The Hospital for Special Surgery. ( info)

5/511. Low power laser therapy and analgesic action.

    OBJECTIVE: The semiconductor or laser diode (GaAs, 904 nm) is the most appropriate choice in pain reduction therapy. SUMMARY BACKGROUND DATA: Low-power density laser acts on the prostaglandin (PG) synthesis, increasing the change of PGG2 and PGH2 into PG12 (also called prostacyclin, or epoprostenol). The last is the main product of the arachidonic acid into the endothelial cells and into the smooth muscular cells of vessel walls, that have a vasodilating and anti-inflammatory action. methods: Treatment was performed on 372 patients (206 women and 166 men) during the period between May 1987 and January 1997. The patients, whose ages ranged from 25 to 70 years, with a mean age of 45 years, suffered from rheumatic, degenerative, and traumatic pathologies as well as cutaneous ulcers. The majority of patients had been seen by orthopedists and rheumatologists and had undergone x-ray examination. All patients had received drug-based treatment and/or physiotherapy with poor results; 5 patients had also been irradiated with He:Ne and CO2 lasers. Two-thirds were experiencing acute symptomatic pain, while the others suffered long-term pathology with recurrent crises. We used a pulsed diode laser, GaAs 904 nm wavelength once per day for 5 consecutive days, followed by a 2-day interval. The average number of applications was 12. We irradiated the trigger points, access points to the joint, and striated muscles adjacent to relevant nerve roots. RESULTS: We achieved very good results, especially in cases of symptomatic osteoarthritis of the cervical vertebrae, sport-related injuries, epicondylitis, and cutaneous ulcers, and with cases of osteoarthritis of the coxa. CONCLUSIONS: Treatment with 904-nm diode laser has substantially reduced the symptoms as well as improved the quality of life of these patient, ultimately postponing the need for surgery. ( info)

6/511. Septic arthritis caused by corynebacterium amycolatum following vascular graft sepsis.

    A case of septic arthritis caused by corynebacterium amycolatum in a native hip joint occurred in an adult man following contralateral vascular graft sepsis, and was successfully treated with intravenous vancomycin followed by oral doxycycline and rifampicin. To the authors' knowledge, this is the only reported case of septic arthritis due to C. amycolatum. ( info)

7/511. Effects of methotrexate treatment on serum immunoreactivity of a patient with normal-pressure glaucoma.

    PURPOSE: Increased serum immunoreactivity to retinal proteins may have a role in the disease process of some glaucoma patients. We describe a patient with normal-pressure glaucoma whose serum immunoreactivity to retinal proteins regressed after methotrexate treatment for rheumatoid disease. METHOD: Case report. RESULTS: In a 66-year-old white female with normal-pressure glaucoma and rheumatoid disease, sequential Western blots using patient sera against retinal proteins demonstrated a decrease in the immunoreactive bands after treatment. During the treatment period of 3 years, her visual fields appeared to have improved. optic disk examination during the short periods without treatment, however, disclosed new, bilateral splinter hemorrhages on the optic disks. CONCLUSION: These observations suggest a potential role for immune-based intervention in similar patients. ( info)

8/511. shoulder joint replacement for osteoarthrosis in association with thalidomide-induced phocomelia.

    The natural history of thalidomide-induced phocomelia has not yet been established since only 35 years have elapsed since the problems associated with this drug became evident. This paper presents what is considered to be the first case of osteoarthrosis in such an individual treated by shoulder joint replacement. Joint arthoplasty is almost certainly going to become an integral part of the life-long rehabilitation process in such affected individuals. ( info)

9/511. diclofenac-associated hepatitis.

    This patient, who had a history of osteoarthritis, had severe hepatitis 5 weeks after being started on diclofenac for increasing pain in the joints. A week before the onset of hepatitis, the patient complained of upper gastrointestinal symptoms and was treated for gastritis. Seven days later, she had full-blown, severe hepatitis. diclofenac was immediately stopped, leading to a complete restoration of liver functions over the course of the next few months. We highlight the importance of having a high index of suspicion for hepatic side effects of diclofenac and emphasize the need for increased awareness of this rare but potentially serious problem. We also review relevant literature regarding incidence and management. ( info)

10/511. osteoarthritis caused by Neocosmospora vasinfecta.

    We report the case of a patient who developed an ankle osteoarthritis due to the Ascomycete Neocosmospora vasinfecta, following accidental multiple trauma to his legs in whilst in africa. Antifungal susceptibility testing was performed. Despite a low amphotericin b minimal inhibitory concentration, parenteral antifungal therapy failed and amputation was required to resolve the osteoarthritis. Possible reasons for the failure of this antifungal treatment are examined. ( info)
