[Osteo-neuro-meningeal-lumbosacral involvement in Marfan syndrome. Report of a case]. / Atteinte ostéo-neuro-méningée lombosacrée au cours du syndrome de Marfan. A propos d'une observation.

Marfan syndrome is an hereditary condition which primarily affects conjunctive tissue with predominant vascular lesions, aortic insufficiency and aortic dissection which condition vital prognosis. Until further progress is made in the genetic determination of the disease, the diagnosis is currently based on the association of clinical criteria, which enables multidisciplinary management. This approach should lead to specific medical and surgical treatment--which may reduce Marfan morbidity and mortality. We report the case of a 45 year-old patient with suspected Marfan syndrome during adolescence. The presence of a cardiovascular lesion and a recently reported abnormality i.e. a sacral erosion by a dural ectasia, enabled us to confirm the diagnosis. We reviewed the current criteria in Marfan diagnosis and their specific management.

[Deep venous thrombosis of the upper limbs. Apropos of 49 cases]. / Les thromboses veineuses profondes des membres supérieurs. A propos de 49 cas.

PURPOSE: Upper-extremity thrombosis appears to be more frequent today, comprising about 2% of all deep venous limb thrombosis. Its severity depends on the type of possible complications, i.e., pulmonary embolism and post-thrombotic sequelae. In this retrospective series, we investigated both the predisposing factors and the evolution of upper-extremity deep venous thrombosis. METHODS: Forty-nine consecutive patients (24 men and 25 women, mean age 50.2 years) with upper extremity deep venous thrombosis documented by color Doppler ultrasonography (n = 47) or phlebography (n = 2) were included in the study. RESULTS: Clinical manifestations were mainly pain (81.6%) and edema (93.9%). Mean time between the onset of clinical signs and diagnosis was 7.2 days. Thrombosis involved humeral (26.5%), axillary (46.9%), subclavian (73.5%) and jugular (24.5%) veins. Causative factors were malignancies (32.7%), venous catheters (22.4%), deep venous thrombosis related to effort or thoracic outlet syndrome (22.5%) and thrombophilic states (8.2%). During the 6-month follow-up, six patients developed symptomatic pulmonary embolism (12.2%); one recurrence (2.2%) and 19 post-thrombotic sequelae such as residual edema (36.7%) were also observed. Initial therapy included heparin administration, principally subcutaneous low molecular weight heparins (n = 36/49). CONCLUSION: This series highlights the fact that upper-extremity deep venous thrombosis is mainly secondary to either malignancies or catheterization. Moreover, it confirms that color Doppler ultrasonography may be useful in the diagnosis of the disease and also underlines the high frequency of severe complications, i.e., pulmonary embolism and post-thrombotic sequelae. Finally, this study also demonstrates that low molecular weight heparins should be considered as the initial treatment of choice.

Computed tomography of sternoclavicular joint lesions in spondylarthropathies.

UNLABELLED: To evaluate the computed tomography (CT) findings of inflammatory lesions of the sternoclavicular joints (SCJ) in spondylarthropathies. DESIGN AND PATIENTS: CT scans of the SCJs were obtained in 23 patients (group 1) with inflammatory SCJ lesions in spondylarthropathies. These scans were reviewed by four readers and compared with the CT scans of 23 matched controls (group 2). Each reader had to complete a 27-item grid. RESULTS AND CONCLUSION: In the 23 patients of group 1, the mean number of observed signs was 5.3 +/- 4.2 higher (P < 0.01) than in the group of 23 matched controls (2.4 +/- 1.6). Four signs were more frequently observed (P < 0.05) in group 1: surrounded subchondral clavicular erosions and cysts, surrounded subchondral sternal cysts and sternal bone sclerosis. A cyst and/or an erosion was associated with hyperostosis and/or bone sclerosis in 9 of 23 patients in group 1. This association was not observed in group 2; the difference was significant (P < 0.001). A cyst and/or an erosive lesion was observed 18 times in group 1 versus 11 times in group 2; the difference was significant (P < 0.05). Conversely, signs of degenerative lesions (osteophytes, subchondral sclerosis, unevenness of joint surface) were no more frequently observed in controls than in group 1. This study emphasizes the diagnostic value of CT, in particular in the identification of inflammatory lesions, even when pre-existing degenerative disease is present.

[Thrombophlebitis and cancer: evaluation of the diagnostic value of abdominal ultrasonography in the acute phase of a deep venous thrombosis. Report of 148 consecutive examinations]. / Thrombophlébite et cancer: évaluation de la rentabilité diagnostique de l'échographie abdominale systématique à la phase aiguë d'une thrombose veineuse profonde. A propos de 148 examens consécutifs.

If an association between venous thromboembolism and malignancy is now well established, there is no consensus about the investigations which should be performed to detect occult malignancy after deep vein thrombosis episode. We investigated the usefulness of systematic abdomino-pelvic ultrasonography in 148 consecutive patients older than 40 with deep vein thrombosis and or pulmonary embolism. Ultrasonography was abnormal in 8 patients (5.4%) and detected only 6 cancers. In 5 cases, clinical examination and laboratory tests were sufficient to suggest malignancy. Our results suggest that ultrasonography should not be systematically performed in patients with deep vein thrombosis. Decisions to performed additional diagnostic tests can be based on the finding of the initial clinical examination, that includes medical history, physical examination, routine laboratory tests and chest-x-ray.

Effects of the low-osmolality contrast medium ioversol (Optiray) on renal function in a geriatric population.

PURPOSE: To assess the incidence of nephrotoxicity following i.v. injection of the iodinated low-osmolality contrast medium ioversol 300 (Optiray) in a geriatric population compared with a control group aged under 60 years, neither group presenting any associated risk factors. MATERIAL AND METHODS: CT with i.v. bolus injection of ioversol 300 mg I/ml was performed at a mean dose of 1.36+/-0.06 ml/kg (range 1-2 ml/kg b.w.) in 47 patients aged over 69 years. Serum creatinine level was measured and creatinine clearance was calculated at 24, 48 and 72 h after the examination, and compared to a reference serum creatinine value taken before CT. The findings were compared with a control group of 44 patients aged under 60 years. RESULTS: No significant increase in serum creatinine (+0.6 mmol/l) or in creatinine clearance (+0.7 ml/min) was found during the course of 3 days after the injection. Only one patient (aged 82) presented an increase of 25% in serum creatinine (109 mmol/l). CONCLUSION: The trial did not demonstrate any significant difference between the 2 groups, although the elderly patients had a subclinical renal impairment revealed by the decrease of the initial creatinine clearance. The use of low-osmolality ioversol makes it possible to perform examination with an iodinated contrast agent without increasing the incidence of nephrotoxicity in elderly subjects.
