[Histochemical diagnosis in pediatric rectal suction biopsies (author's transl)]

Between March 1972 and Dec. 1974 532 rectal suction biopsies were obtained from 238 children and histochemical processed. Slight haemorrhage was observed in three. Indications were :1) Group A, 185 suspected aganglionism (AChE. and DPNH) activities were studied). 2) Group B, 7 Neurolipidoses (Red-oil-o) and 3) Group C, Post-operative control in 10 aganglionic patients (AChE, DPNH). Aganglionism was confirmed in 60 cases (25.2%) of Group A [AChE (+), DPNH (-)] although there were five false negatives (8.3%). Lipidosis was confirmed in one case of Group B. Four patients in Group C were AChE and DPNH (+). Results are discussed, and this technique recommended taking in mind its minimal morbidity, simplicity and good results.

[Tumors of the endodermal sinus (author's transl)]

Seven cases of tumors of the endodermal sinus are reviewed. This is a highly malignant germinal tumor, arisen from extraembrionary cell differentiation. It is different both biologically and pathologically from sacrocoxigeal teratoma. There are no survivors in these series. All seven patients have been surgically treated chemotherapy has been used in four, and X-ray therapy in two. It is noteworthy that alpha-phetoprotein is present in patients with this type of tumor. This fact can be used both in diagnosis of the tumor and of its recurrence.
