    Description / Table of Contents: Zusammenfassung Ein Fall von kindlicher Triploidie wird vorgestellt. Die Schwangerschaft war gekennzeichnet durch therapieresistente EPH-Gestose im 2. Trimenon mit Übergang in Präeklampsie in der 33. Woche. Der durch Sectio entbundene, nicht lebensfähige Fetus war äußerlich weiblich, untergewichtig, hypoton und asphyktisch. Er wies eine Hirnmißbildung mit Kebozephalie, einem großen univentrikulären Hohlraum und Fehlen der Hypophyse sowie multiple Mißbildungen und dysmorphe Zeichen auf. Bei der Sektion fanden sich Hypo- und Dysplasie der Nebennieren; Uterus, Tuben und Ovarien waren nicht angelegt, Testes waren nicht nachweisbar. Die Plazenta war auffallend groß und zeigte herdförmige hydatidiforme Degenerationen der Zotten. Der Karyotyp war 69,XXY, und mit Hilfe der Fluoreszenzmarker ließ sich der väterliche Ursprung des überzähligen haploiden Satzes nachweisen. Die für Triploidie typischen Schwangerschaftsbefunde werden besprochen und auf die Möglichkeit der pränatalen Diagnose durch Chromosomenuntersuchung an gezüchteten Zellen der Amnionflüssigkeit wird hingewiesen.
    Notes: Summary The authors report a case of triploidy in a prematurely born child. The pregnancy was complicated by severe toxemia beginning during the second trimester and terminating in preeclampsia leading to cesarian section in the 33th week of gestation. The externally female child was underweight, hypotonic and asphyctic and died shortly after birth. She exhibited a complex brain malformation including excessive hydrocephaly, cebocephaly and aplasia of the piturary gland, and multiple dysmorphic signs. Autopsy revealed hypoplasia and dysplasia of the adrenal glands; no uterus, tubes and ovaries were present, but no testes were found. The placenta showed localized hydatidiform degeneration and was relatively large. The karyotype was 69,XXY, and with the aid of fluorescence markers, paternal origin of the additional haploid chromosome set was demonstrated. Typical findings in pregnancies with fetal triploidy are discussed and the possibility of prenatal diagnosis of triploidy by chromosome analysis in cultivated amniotic fluid cells is pointed out.

    Description / Table of Contents: Zusammenjassung 3 Patienten mit dem 18q — Syndrom, 2 Knaben und 1 Mädchen, werden vorgestellt und mit den Fällen der Literatur verglichen. Die folgenden typischen Merkmale des 18q — Syndroms fanden sich bei ihnen: Kleinwuchs, Schwachsinn, muskuläre Hypotonie, Gesichts- und Ohrdysmorphie, Kryptorchismus bei den Knaben sowie zurückversetzte Daumen, konisch zulaufende Finger, Häufung von Wirbelmustern auf den Fingerbeeren und nach dorsal versetzte 2. Zehen. 2 Patienten zeigten die für das 18q — Syndrom typische Mittelgesichtsdysplasie sowie Hypertelorismus und Strabismus, hingegen wiesen alle drei Nystagmus und eine charakteristische Ohrdysmorphie mit Vortreten von Anthelix und Antitragus auf. Je 2 Patienten waren schwerhörig bzw. hatten auffallend enge Gehörgänge. Bei einem Fall fanden sich noch ein Iris- und Chorioideakolobom, Opticusatrophie und eine Lippenspatle, bei einem anderen eine Nabel- und Leistenhernie. Bei 2 Patienten war die Deletion des langen Arms von Chromosome 18 neu entstanden, bei einem war der Vater Träger einer balancierten Translokation t(15;18)(q24;q21).
    Notes: Summary 3 cases of the 18q — syndrome, 2 boys and 1 girl, are presented, and a comparison with data from the literature is given. The following features are typical of the syndrome: short stature, mental retardation, muscular hypotonia, a peculiar dysmorphia of the face and ears, cryptorchidism and small scrotum in males, proximally implanted thumbs, tapering fingers, excess of whorls on the fingertips, and dorsally implanted second toes. Midface hypoplasia with hypertelorism and cleft palate, as well as strabismus, were present in 2 of our patients, whereas all 3 showed nystagmus and prominence of anthelix and antitragus. In addition, 2 patients exhibited narrow ear canals and impaired hearing. One patient had coloboma of the iris and choroid, pale optic discs, and cleft lip; another had umbilical and inguinal hernias. Two cases represented de novo deletions of the long arm of chromosomes 18, whereas the karyotype of the father of the third case revealed a balanced translocation t(15;18)(q24;q21).

    Notes: Summary Chromosome studies on lymphocyte cultures were performed in 5 patients with AT, 2 of whom had been followed for 4 years. Four out of these patients showed an increased incidence of chromosome-type aberrations. A clonal development was present in one patient, 96% of his metaphases containing a tandem duplication of almost the entire long arm 14. Four years earlier the proportion of these cells was 80%. Two other patients presented a small proportion of cells with an unidentified abnormally long D chromosome. In a total of 724 metaphases from 4 patients 31 dicentric chromosomes were observed, all of a peculiar type: in their formation no chromosome material was lost and they all seem to have arisen by end-to-end fusions. The incidence of chromatid-type aberrations was normal or at the upper limit of control values in all 5 cases. The sister chromatid exchange rate studied with BUDR in 3 patients was found to be normal.

    Notes: Summary Amniocentesis was performed in a pregnancy of 26 weeks because of hydramnios. The amniotic fluid was examined for fetal karyotype and AFP content. The latter was elevated to 300 μg/ml. Fetal death occurred shortly after amniocentesis and a malformed male fetus with a large sacrococcygeal teratoma was stillborn 3 days later.

    Notes: Summary In the 33rd week of pregnancy an amniocentesis was performed because of low estriol. X-ray indicated the presence of anencephaly and a premature delivery was induced. Necropsy, in addition to anencephaly, showed a wide variety of malformations. The fetal karyotype determined from cultured amniotic fluid cells revealed a ring chromosome 13.

    Notes: Summary The incidence of structural chromosome aberrations and the rate of sister chromatid exchanges (SCE) was investigated in lymphocyte cultures from a patient with typical Fanconi's anemia and his parents. The rate of SCEs was found to be normal. In experiments with the alkylating agent Trenimon the SCE rates proved to be a sensitive indicator for the induction of structural aberrations: in presence of an induced aberration rate half as high as the spontaneous rate in the Fanconi's anemia case, the rate of SCEs was found to be quintupled. Dose-effect relationships for the induction of SCE rates by Trenimon were studied over a wide dose range in lymphocyte and fibroblast cultures. The results reflect the same difference in sensitivity earlier observed in the induction of structural chromosome aberrations, fibroblasts being far more sensitive.
