[Negative bone scintigraphy in osteomyelitis in children. Difficulties in interpretation].

The authors relate 7 cases of hematogenous osteomyelitis in children where skeletal scintigraphy with TC 99m diphosphonate was said as normal. They analyse the lack of positive radionuclide findings; misinterpretation, abnormal tracer accumulation which probably relates to regional hyperemia, transient area of discreased uptake of the tracer in the early phase of the disease and real negative bone scan; these cases are rare; when there is a high suspicion of osteomyelitis in spite of a normal bone scan Gallium imaging may be helpful.

[Endolymphatic curietherapy by lymphography with labelled lipiodol in Hodgkin's disease. A report on 408 cases (author's transl)].

The results of 373 lymphography examinations with radioactive lipiodol, conducted in 408 patients with Hodgkin's disease for diagnostic and prophylactic therapeutic purposes, during investigations carried out from 1966 to 1973 are analyzed. Tolerance was always excellent, especially from the hematological point of view. The efficacy of the procedure can be assessed by the fact that there were only 6% of failures (21/373) in glandular regions irradiated in this way for prophylactic purposes. Relapses occur more frequently in the inguino-iliac and lumbo-aortic regions than in the pelvic chains which were perfectly protected. This technique also enables both pelvic irradiation and ovarian protection in young women without any risk of failure. The procedure is particularly indicated in the following cases: supradiaphragmatic stages I and II, whatever the sex, and stage III especially in women. In sub-diaphragmatic stages I and II, it allows, in favourable cases, the ovarian function in women to remain intact by limiting external irradiation to invaded regions only.

[Bone scanning in children: technic and indications. Apropos of 50 cases].

In children, radionuclide skeletal imaging with 99m Tc M. D.P. has been performed in 50 cases. Scans are done immediately, 20 minutes and three hours after injection. Osteomyelitis has been studied in 24 cases, Legg Perthes disease and benign bone tumors in the others. The scintigraphic patterns are very sensitive but not characteristic. However this exam seems to be essential in some orthopedic disorders of children.
