[Cytological complications of IUDs ].

The cytological modifications due to IUDs are incompletely or inaccurately known to clinicians and cytologists. IUDs of all types bring about a modification of the maturation index, and particularly of the estrogenic index which, throughout the cycle, appears to be lower than that of a control group. The presence of a sub-normal inflammatory contest in smears of IUD users is no proof of an increased incidence of microbic infections. Presently there is no sign of any carcinogenic role played by IUDs. The papillary metaplasia induced by IUDs appeared more frequently than squamous endometrial metaplasia.

Computed tomography in ileofemoral venous thrombosis: extension to inferior vena cava defined with foot vein infusion.

Two cases of ileofemoral venous thrombosis and occlusion are presented in which cephalad extension of venous thrombosis to the inferior vena cava (IVC) is demonstrated on computed tomography (CT). Proximal venous obstruction does not diminish the utility of foot vein infusion simultaneous with the CT study. Delineation of intraluminal thrombosis in the IVC is excellent with good definition of occluded and patent segments of the IVC.

"Doughnut" sign in brain scanning.

The significance of the "doughnut" sign at present is relegated to characterizing the morphology of a lesion. The use of the "doughnut" sign in differential diagnosis should not be attempted except in specific clinical contexts, and never excluding other evidence. The "doughnut" sign in scanning together with other studies such as angiography and computerized axial tomography gives additional characterizing data in the neuroradiologic evaluation of a patient.

Spinal cord toxoplasma lesion in AIDS: MR findings.

Toxoplasma gondii is the cause of the most common opportunistic infection of the brain in AIDS but is extremely rare as the cause of a solitary lesion of the spinal cord. Symptoms are weakness of the lower limbs followed closely by paralysis unless diagnosed and treated early. We present such a case in an intravenous drug abuser with AIDS and emphasize that MRI is the diagnostic tool of choice and that the index of suspicion should be high in immunosuppressed patients.

Lumbar intervertebral disk herniation in teenage children: recognition and management of associated anomalies.

Herniated disks in children and adolescents can be extremely disabling and difficult to diagnose because of the paucity of neurologic abnormalities and the consequent suspicions of hysteria. The Laségue sign is often the only consistent positive finding, and when persisting without remission, justifies early diagnostic studies such as CT scanning, and electromyography. Myelography may be avoided if these studies are definitively diagnostic. The almost uniformly good results that follow diskectomy do not justify prolonged conservative care. Management is facilitated by awareness of often unrecognized structural abnormalities found in these patients. These include spinal stenosis, lateral recess narrowing, and transitional vertebra. Spinal fusion, while rarely indicated, should be considered where motion segment instability contributes to persistent backache. The management of 25 patients is recorded. Twenty-one of these presented with an anomaly worthy of record requiring modifications in surgical technique to provide proper decompression and lasting relief of symptoms.

[Triple ureter. One case. Diagnostic problem and review of the literature (author's transl)].

In the light of a case of right triple ureter in a 5 month old girl, the authors review the embryology of the ureter and describe the different types of triplication. A general review of the literature including 70 cases gives an indication of the circumstances of discovery and the contribution of radiology. The complications of complete ureteral triplication are the same but greater than those of complete duplication and are related to the ectopic position of the ureteral orifices with regard to the trigone. They are dominated by reflux and stasis in the case of high ectopia and by false incontinence (20% of cases) in low ectopia.
