Resume Le traitement endoscopique du reflux vesico-ureteral par implant de polydimethylsiloxane (Macroplastique ® ) a montre son interet, mais les complications a long terme en sont encore mal connues. Une adolescente de 15 ans se plaignait de douleurs en fosse iliaque droite avec boiterie d’esquive. Apres de multiples explorations, le diagnostic de colique nephretique sur calcification de l’implant de Macroplastique ® a ete pose. Des cas de calcification d’implant de Macroplastique ® , mais aussi d’autres types d’implant, ont ete decrits dans la litterature, mais leurs manifestations cliniques sont mal connues, faisant errer le diagnostic. La prise en charge peut aller jusqu’a une exerese du materiel implante, voire la reimplantation ureterale.

The measurement of ileal digestibility of amino acids is recognized to be a valid tool for the estimation of availability of amino acids. One of the techniques used to obtain this measure - ileal rectal anastomosis - has, however, received a lot of criticism since it has been claimed that the removal of the colon from the active digestive tract leads to the development of a colon-like microflora in the ileum (Köhler et al, 1991). The aim of this experiment was to evaluate if the possible development of microflora affected the ileal digestibility results obtained.

The diagnosis of free hernia remains the most difficult problem in percutaneous lumbar surgery. We thought we could obtain better results by using systematic CT discography (CTD) before percutaneous lumbar discectomy [2–4].

ERRONEOUS diagnoses of neurosyphilis are sometimes made in cases of neurologic syndromes because of a history and serologic evidence of syphilis and the presence of abnormalities in the cerebrospinal fluid. It is generally recognized that examination of the cerebrospinal fluid is essential for the diagnosis of neurosyphilis. As shown in a previous report, 1 the reagents and procedures used in such tests should be quantitatively standardized in order to yield accurate and reproducible results. They should include a cell count, determination of total protein and a colloidal gold test of the cerebrospinal fluid, as well as quantitative complement fixation tests of both the cerebrospinal fluid and the blood. 2 Furthermore, the results of the tests of the cerebrospinal fluid should have a quantitative relation to each other, so that together they form a syndrome reflecting the activity and character of the syphilitic inflammatory process. The result of each test should

It is generally recognized that certain types of acquired sinuses and fistulous tracts, resistant to the more ordinary forms of treatment, have been successfully healed by means of the galvanic current. Since none of the cases of pilonidal cysts (sacral fistulas) reported in the literature have been treated by this method, an account is given here of such a case. Pilonidal cysts (sacral fistulas) are considered to be developmental anomalies and have been successfully healed only by complete excision of the tract or tracts. Other methods of treatment, such as incision or cauterization with chemicals, have accomplished only temporary relief. REPORT OF CASE History and Examination. —A hairy, thick set, dark complexioned white man, aged 22, had had a troublesome discharge occurring near the anus for about six months. A year previously he had experienced the same kind of discomfort, but at that time the discharge stopped without any treatment.
