Introduction of a rapid, simple radioimmunoassay and quality control scheme for thyroxine.

A simple radioimmunoassay has been developed for service purposes to determine serum total thyroxine levels. Only three additions are required, of standard or sample, labelled thyroxine and antibody in polyethylene glycol. After 2 hours' incubation at room temperature the antibody-bound and free fractions are separated by centrifugation. Serum total thyroxine levels were measured in 195 euthyroid subjects and it was established that normal values lay within the range 57 to 155 nmol/1. Serial blood samples taken over a 24-hour period, from 11 subjects, indicated that there was no circadian rhythm so that samples for total thyroxine assay can be taken at any time of the day. Similar results were obtained using serum or plasma. Satisfactory results were obtained for three quality control sera when measured by seven different laboratories using this method.

[Vertebral angiography and tumours of the posterior fossa in children. 29 cases (author's transl)].

With reference to 29 cases of tumours of the posterior fossa, the authors attempt to place the value of vertebral angiography amongst other diagnostic techniques and in particular in relation to ventriculography using iodised hydrosoluble contrast media. Whilst recognising the diagnostic possibilities offered by vertebral angiography, they feel that, in many cases, opacification of the IVth ventricle is necessary and that angiography does not therefore form part of the routine pre-operative assessment of such tumours.

[A rare cause of antro-pyloric stenosis in the child: septic granulomatosis. Concerning one case (author's transl)].

Presentation of a case of pyloric stenosis in a five year old boy due to a granuloma during the course of septic granulomatosis. The discussion must enable one to evoke the diagnosis when it is a known case of granulomatous disease, and consequently to treat it medically with antibiotics. In the opposite case where the disease is not known, it is a question of etiological discussion of pyloric stenosis. It is now worth thinking of septic granulomatosis routinely with the more classical causes of pyloric stenosis in the order boy.

[Cholesterol pneumonia in a child (author's transl)].

The case presented is that of a pneumonia due to cholesterol in a young girl of 13 years old. The clinical picture was that of severe progressive pulmonary fibrosis. On histology, a foreign body reaction around cholesterol crystals was found. The history enabled confirmation of the endogenous origin of this fatty infiltration.

[Renal localization of lymphosarcoma in the child (author's transl)].

Eight children with renal localization of a lymphosarcoma are presented. Intravenous pyelography is generally carried out in the systematic full check-up of a known case of lymphosarcoma, in order to determine the degree of extension of the disease and in order to adapt chemotherapy. The different radiological appearances are discussed. They more frequently lead to the diagnosis of more well known conditions when the diagnosis of lymphosarcoma has not yet been established.
