Our experience with the combination of dacarbazine, carmustine, cisplatin with and without tamoxifen is reported. In our initial study, with all 4 drugs, we had an overall response rate of 50% with a complete response rate of 15%. Due to a high incidence of deep venous thrombosis and the lack of effectiveness of tamoxifen as a single agent, we deleted tamoxifen from the regimen and treated another 20 patients. Surprisingly, the response rate decreased to 10%. We then re-incorporated tamoxifen into the regimen and treated 25 additional patients. In this third group of patients we experienced an objective response rate of 52% with a complete response rate of 8%. Overall, 65 patients have been treated: 45 with and 20 without tamoxifen. Twenty-three (51%) patients treated with tamoxifen have responded, with 5 (11%) patients achieving a complete response. Only 2 (10%) patients treated without tamoxifen have responded. Despite the improvement in the response rate, a corresponding increase in survival has not been seen. Patients treated with tamoxifen had a mean survival of 10.8 (SD 13.6) months compared with a mean survival of 9.8 (SD 7.3) months for those treated without tamoxifen. The absence of survival advantage for the tamoxifen-treated patients may be due to early failure in the central nervous system. In 48% of the responding tamoxifen-treated patients, the first site of failure was the central nervous system, while systemic disease was still responding.

The presence of a lupus anticoagulant (LA) is paradoxically associated with a high incidence of arterial and venous thrombosis. In a patient with a lupus-like systemic disease, having received phenindione for 11 years, LA was discovered in association with recurrent deep venous thrombosis, a right atrial thrombus, coronary occlusion, arterial hypertension, thrombopenia, and anticardiolipin antibodies without anti-DNA antibodies. Renal cortical ischemia was detected by a tomographic scan. Renal biopsy showed glomerular ischemia and diffuse interstitial fibrosis. After a one-year anticoagulant and steroid therapy, LA has disappeared despite a high level of anticardiolipin antibodies, and renal function remains normal.

Eighteen patients with bone fractures and without systemic disease were studied for blood rheology. Blood and plasma viscosities, haematocrit, red cell aggregation and filterability as well as plasma colloid oncotic pressure were measured. Results show that patients exhibit a substantial haemorheological deficit on admission. During bedrest this returns to normal, owing to marked 'autohaemodilution'. It is concluded that trauma causes increased viscosity of blood in these patients. This change could predispose to deep vein thrombosis. However, such a risk is reduced by 'autohaemodilution' which is most probably an effect of immobilization.

With regard to deep vein thrombosis, superficial thrombophlebitis of lower limbs have a reputation of mildness disease that the experience gained from widely used duplex scanning in their evaluation comes to question. Short superficial thrombophlebitis on non-varicose veins often remain a symptom belonging to or revealing a systemic disease. Superficial thrombophlebitis on varicose veins are of two kinds: short superficial thrombophlebitis remain a common complication of varicose phlebectasia but they must be differenciated from extensive saphenous thrombophlebitis. The first ones are of local symptomatic treatment and of varicose vein surgery. The last ones are associated--with deep vein thrombosis in 10 to 30% of case (either by extension from the saphenous to the deep veins, either without anatomical link), with clinical pulmonary embolism in 5% of cases, and with a cancer in about 10% of cases. Numerous superificial venous thrombosis occur without inflammatory signs and the clinical diagnosis of extensive superficial venous thrombosis is as difficult as the one of deep vein thrombosis. So the diagnosis, the treatment, the etiological investigation of extensive superficial venous thrombosis are in fact not very different from those of deep vein thrombosis.

The worldwide prevalence of hip fracture is increasing as the mean age of the population increases. Despite advances in anesthesia, nursing care, and surgical techniques, however, the outcome of treatment is often poor, and hip fractures remain a significant source of morbidity and mortality for the elderly population. For these patients, operative treatment is considered to be optimal and most cost-effective for displaced intracapsular fractures and all extracapsular fractures. Undisplaced intracapsular fractures can be treated with bed rest and 6-8 weeks' delay of weight bearing in the "younger" elderly (< or = 70 years). The timing of surgery remains controversial, and evidence that a delay in operating leads to increased morbidity is inconclusive. In general, early surgery is indicated in premorbidly fit patients, whereas surgery should be delayed if correctable comorbidities are present. Methods of intracapsular fracture repair very geographically and according to surgeon preference. Prospective, randomized, case-controlled studies are needed to compare repair methods, including internal fixation versus hemiarthroplasty for intracapsular fractures and use of uncemented versus cemented hemiarthroplasty protheses. Extracapsular fractures are usually repaired using a dynamic hip screw or other variant of sliding nail fixation. The mortality rate after hip fracture appears to vary in association with poorly controlled systemic disease (particularly if multiple comorbidities are present); cognitive disorders; operative intervention before stabilization if > or = 3 comorbidities are present; and, in the absence of prophylaxis, deep vein thrombosis; the associations between mortality and male sex, advanced age, and anesthetic type are less clear. The factors associated with the recovery of walking ability include young age, male sex, absence of dementia, absence of postoperative confusional state, and use of a walking aid before the fracture. Many determinants of outcome are independent of the level of care given and are dependent on prefracture status. To maximize rehabilitation potential, a multidisciplinary approach using skilled medical, nursing, and paramedical care appears to be optimal. Prospective case-controlled studies are required to demonstrate the long-term effectiveness of specialist rehabilitation units. In today's cost-cutting environment, caution must be taken to prevent short-term cost-saving measures from compromising long-term outcome for elderly hip fracture patients.

The authors report their experience with 42 patients in whom anterior lumbar fusion was performed using titanium cages as a versatile adjunct to treat a wide variety of spinal deformity and pathological conditions. These conditions included congenital, degenerative, iatrogenic, infectious, traumatic, and malignant disorders of the thoracolumbar spine. Fusion rates and complications are compared with data previously reported in the literature. Between July 1996 and July 1999 the senior authors (C.I.S., R.P.N., and M.J.R.) treated 42 patients by means of a transabdominal extraperitoneal (13 cases) or an anterolateral extraperitoneal approach (29 cases), 51 vertebral levels were fused using titanium cages packed with autologous bone. All vertebrectomies (27 cases) were reconstructed using a Miami Moss titanium mesh cage and Kaneda instrumentation. Interbody fusion (15 cases) was performed with either the BAK titanium threaded interbody cage (in 13 patients) or a Miami Moss titanium mesh cage (in two patients). The average follow-up period was 14.3 months. Seventeen patients had sustained a thoracolumbar burst fracture, 12 patients presented with degenerative spinal disorders, six with metastatic tumor, four with spinal deformity (one congenital and three iatrogenic), and three patients presented with spinal infections. In five patients anterior lumbar interbody fusion (ALIF) was supplemented with posterior segmental fixation at the time of the initial procedure. Of the 51 vertebral levels treated, solid arthrodesis was achieved in 49, a 96% fusion rate. One case of pseudarthrosis occurred in the group treated with BAK cages; the diagnosis was made based on the patient's continued mechanical back pain after undergoing L4-5 ALIF. The patient was treated with supplemental posterior fixation, and successful fusion occurred uneventfully with resolution of her back pain. In the group in which vertebrectomy was performed there was one case of fusion failure in a patient with metastatic breast cancer who had undergone an L-3 corpectomy with placement of a mesh cage. Although her back pain was immediately resolved, she died of systemic disease 3 months after surgery and before fusion could occur. Complications related to the anterior approach included two vascular injuries (two left common iliac vein lacerations); one injury to the sympathetic plexus; one case of superficial phlebitis; two cases of prolonged ileus (greater than 48 hours postoperatively); one anterior femoral cutaneous nerve palsy; and one superficial wound infection. No deaths were directly related to the surgical procedure. There were no cases of dural laceration and no nerve root injury. There were no cases of deep venous thrombosis, pulmonary embolus, retrograde ejaculation, abdominal hernia, bowel or ureteral injury, or deep wound infection. Fusion-related complications included an iliac crest hematoma and prolonged donor-site pain in one patient. There were no complications related to placement or migration of the cages, but there was one case of screw fracture of the Kaneda device that did not require revision. The authors conclude that anterior lumbar fusion performed using titanium interbody or mesh cages, packed with autologous bone, is an effective, safe method to achieve fusion in a wide variety of pathological conditions of the thoracolumbar spine. The fusion rate of 96% compares favorably with results reported in the literature. The complication rate mirrors the low morbidity rate associated with the anterior approach. A detailed study of clinical outcomes is in progress. Patient selection and strategies for avoiding complication are discussed.

Bilateral Achillies tendon ruptures are a rare occurrence that usually occur in patients with chronic systemic disease. Many cases are also associated with corticosteroid or fluoroquinolone use. Nonoperative treatment is generally indicated in this patient population, as the patients are often considered poor surgical candidates. Nonoperative immobilization, however, conveys the risk of developing deep venous thrombosis and pulmonary embolism. Such risks are even greater in patients displaying bilateral Achilles tendon ruptures. In this report, we illustrate the case of a near-fatal pulmonary embolism as associated with bilateral spontaneous Achilles tendon ruptures. We also review the current literature and make recommendations for prophylaxis and treatment of these potentially devastating complications.

Superficial vein thrombophlebitis (SVTP) appears in two distinct forms: varicose vein thrombophlebitis (TP) represents the principal cause. It is characterized by a large thrombus in a varicose vein and a modest inflammatory process localized in the vessel surrounding but not in its wall. Rarely, SVTP affects a non-varicose vein. Abundant intima proliferation and media fibrosis with non-important thrombosis are the hallmark of this form which may be associated with a systemic disease. Although SVTP is perceived as trivial and benign coexistence of (mostly distal) deep venous thrombosis (DVT), propagation to popliteal or femoral DVT, and even pulmonary embolism (PE) have been reported. Data for prevalence vary greatly: 6-53% for coexistence, 2.6-15% for propagation, and 0-33% for (asymptomatic) PE. Risk factors for these complications are those known for DVT. SVTP is diagnosed in a clinical setting but ultrasonography is useful to check for concomitant DVT. Anticoagulant treatment is mandatory if DVT is present and thrombectomy should be considered in cases of thrombus propagation into the deep veins. Historical therapy of uncomplicated SVTP consists of compression with bandages or stockings and local or systemic anti-inflammatory agents. Low-molecular-weight heparin (LMWH) has been given in high-prophylactic doses and found equally effective when compared with anti-inflammatory agents and full-therapeutic dose LMWH. Prophylactic saphenous vein ligation alone was found less effective than conservative therapy. Ligation combined with stripping proved the potential of eliminating at once all problems associated with SVTP but was associated with a complication rate of 10% or higher. Careful patient selection and saphenous vein thrombectomy prior to stripping may be the clue for better results.

Inferior vena cava filter placement is performed to prevent pulmonary risk secondary to deep venous thrombosis. Indications for this treatment are limited to patients experiencing recurrences under well-managed anticoagulant treatment or presenting with contraindication to anticoagulant treatment. Nowadays, as these clinical situations are rare, this device is less and less used, all the more since, for several years now, thrombosis, fracture, or infectious complications as well as filter migration have been reported. Filter migrations are responsible for atypical and varied clinical presentations likely to defer diagnosis. To treat them, the filter is extracted, which is very risky in patients with a thromboembolic history. In our center, during a period of 14 years, we retrospectively collected and studied partial or complete vena cava filter migration cases that had been treated by extraction. We are reporting four very different clinical cases and, more specifically, the second published case of migration to a renal vein, which mimicked a systemic disease. Because of its very atypical clinical presentations, cava filter migration is an unappreciated and certainly underdiagnosed complication. However, this complication must not question cava filter placement when it is justified. In contrast, it prompts early filter extraction or long-term radiological surveillance.

Patients with recurrent uveitis are often evaluated for the presence of underlying systemic disease. The authors describe a 55-year-old black female who presented with isolated recurrent anterior uveitis. Laboratory evaluations were notable for elevated inflammatory markers. She subsequently developed left lower extremity painless swelling; ultrasound evaluation was negative for deep venous thrombosis. CT scan of her abdomen and pelvis demonstrated multiple amorphous soft tissue densities throughout the small bowel mesentery and retroperitoneum, associated with left-sided hydronephrosis. Histopathology of a retroperitoneal mass demonstrated retroperitoneal fibrosis (RPF). Treatment with systemic corticosteroids led to shrinkage of her mesenteric and retroperitoneal masses, resolution of uveitis and normalisation of inflammatory markers. Albeit rare, RPF should be considered in the diagnostic investigation of patients with recurrent uveitis, especially those with abdominopelvic or lower extremity complaints.
