ABSTRACT

We report on a family of three consecutive fetuses affected by type IV glycogen storage disease (GSD IV). In all cases, cervical cystic hygroma was observed on the 12-week-ultrasound examination. During the second trimester, fetal hydrops developed in the first pregnancy whereas fetal akinesia appeared in the second pregnancy. The diagnosis was suggested by microscopic examination of fetal tissues showing characteristic inclusions exclusively in striated fibers, then confirmed by enzymatic studies on frozen muscle. Antenatal diagnosis was performed on the third and fourth pregnancies: cervical cystic hygroma and low glycogen branching enzyme (GBE) activity on chorionic villi sample (CVS) were detected in the third pregnancy whereas ultrasound findings were normal and GBE activity within normal range on CVS in the fourth pregnancy. Molecular analysis showed that the mother was heterozygous for a c.1471G > C mutation in exon 12, leading to the replacement of an alanine by a tyrosine at codon 491 (p.A491T); the father was heterozygous for a c.895G > T mutation in exon 7, leading to the creation of a stop codon at position 299 (p.G299X). GSD IV has to be considered in a context of cervical cystic hygroma with normal karyotype, particularly when second trimester hydrops or akinesia develop. Enzymatic analysis of GBE must be performed on CVS or amniotic cells to confirm the diagnosis. Characteristic intracellular inclusions are specific to the disease and should be recognized, even in macerated tissues after fetal death. Genetic analysis of the GBE gene may help to shed some light on the puzzling diversity of GSD IV phenotypes.

ABSTRACT

We report the case of a young female patient hospitalized for the first episode of a colonic Crohn's disease with specific ulceronecrotic tracheobronchial involvement leading to chronic and invalidant cough. Symptomatic bronchopulmonary manifestations are very rare in the course of inflammatory bowel diseases and usually not mentioned in Gastroenterology textbooks.

ABSTRACT

AIMS: (i) To investigate and compare the numerical aberrations of chromosomes 7, 8, 11, 17 and Y in a series of 60 adenocarcinomas of the oesophagus, gastric cardia and gastric antrum; and (ii) to specify the sequence of chromosomal aberrations occurring during the neoplastic progression of Barrett's oesophagus. METHODS AND RESULTS: Chromosomal in-situ hybridization was performed on deparaffinized tissue sections from 20 Barrett's adenocarcinomas, 20 adenocarcinomas of the cardia and 20 adenocarcinomas of the antrum, with centromeric alpha satellite DNA probes specific for chromosomes 7, 8, 11, 17 and Y, labelled with digoxigenin. Signals were detected by immunoperoxidase staining. The copy number for each chromosome was counted in 200 tumour cells nuclei and 100 lymphocytes as controls. In parallel, the DNA content of the nuclear suspensions was measured by flow cytometry. Numerical abnormalities of the five chromosomes (loss of the Y chromosome, monosomy, trisomy, and tetrasomy) were frequently observed in the three groups of adenocarcinomas (from 40% to 65% of the cases). Sixty per cent to 75% of oesophagus and gastric adenocarcinomas were DNA-aneuploid. Chromosomal aberrations progressively increased with advancing degrees of dysplasia in Barrett's mucosa, with an increasing frequency of trisomy and loss of the Y chromosome from non-dysplastic Barrett's mucosa to invasive adenocarcinoma, and with monosomy and tetrasomy present only in invasive cancers. CONCLUSION: Our study confirms the high frequency of chromosomal numerical aberrations in oesophageal and gastric adenocarcinomas, without differences between adenocarcinomas of the gastric cardia and antrum. We have shown that these alterations occur early during the neoplastic transformation of Barrett's mucosa.

ABSTRACT

A whole body scan is performed after a radioiodine treatment in patients with differentiated thyroid carcinoma. This scan is useful coupled with thyroglobulin level for the patient's management. When unusual uptake is found, investigations have to be done to eliminate thyroid metastasis. A 28-year old woman underwent a total thyroidectomy for micro papillary carcinoma. Two years and a half after, ultrasonography of the neck showed a small lymph node in homolateral side of carcinoma. It was decided to begin treatment with iodine 131. The post-therapeutic scan showed an abnormal pelvic uptake. IRM found no osseous abnormality but an ovarian lesion. After surgery, histological diagnosis was an endometriosis cyst without thyroid or tumoral cells. Abdominal ou pelvic iodine false positive are rare. Ovarian cysts may be the cause of false positive radioiodine uptake. Endometriosis cyst was not previously described and the mecanism of iodine uptake is not clear.
