Sublocalization of putative tumor suppressor gene loci on chromosome arm 14q in neuroblastoma.

RFLP and microsatellite analysis with 23 polymorphic markers spanning the entire long arm of chromosome 14 in 108 neuroblastomas showed allelic loss in 19 out of 107 (18%) informative tumors, placing 14q among the most frequently affected chromosomal regions in neuroblastoma. One minimal deletion region could be sublocalized in 17 of 19 cases between markers D14S1 and D14S16, and a second one between markers D14S17 and D14S23 in band 14q32. Furthermore, breakpoints in bands 14q23 and 14q12 were detected. These results suggest the presence of at least two putative tumor suppressor gene loci on chromosome 14. Survival analyses revealed no prognostic impact of allelic loss of 14q in neuroblastoma. Genes Chromosomes Cancer 26:40-46, 1999.

[Hypertrophic gastritis in an infant with eczema and intolerance to cow's milk proteins (author's transl)].

A 5-month-old infant presented with vomiting and severe hypoproteinemia from exsudation of proteins into the digestive tract, confirmed by isotopic tests. The association of hypertrophic edematous gastritis, interstitial jejunitis, and severe blood eosinophilia suggested the diagnosis of an exsudative eosinophil-type gastro-enteropathy. An allergy to cow's milk proteins was suspected because of the onset of the disorders at the time of weaning and the appearance of the eczema during the same period. Clinical, biological, and radiological recovery occurred after an exclusion diet and corticotherapy, and this persisted for 8 months, but the eczema remained. The authors describe a similar case (12) in an infant of 21 months with vomiting edema, and hypoproteinemia due to exsudation of proteins into the digestive tract. Radiological examination revealed the presence of hypertrophic gastritis. A relationship with Mentrier's disease had been suggested but not confirmed because of the rapid favourable outcome after a simple low protein diet.
