Cystic hygroma: prenatal diagnosis and genetic counselling.

Six cases of cystic hygromas detected during second trimester ultrasound examination are reported: 4 fetuses (67 per cent) had a 45, X karyotype, 1 fetus had trisomy 18, 1 fetus had a normal karyotype (46,XX) and at autopsy multiple anomalies were observed. In the latter case the family history suggested an autosomal recessive pattern of inheritance. In order to reach a definite diagnosis and give proper genetic counselling when a fetus is found to have cystic hygroma, a fetal karyotype as well as a family and reproductive history should be obtained.

Cost-effectiveness ratio of chorionic villi biopsy for the prenatal diagnosis of chromosomal aberrations as compared with amniocentesis.

The observed cost of amniocentesis for the prenatal diagnosis of chromosomal aberrations in pregnancies at risk because of advanced maternal age was compared with the estimated cost of chorionic villi biopsy (CVB). The cost of CVB was estimated to be 22% less than that of amniocentesis when the cost of the sampling procedure, the laboratory charges and the cost of spontaneous and therapeutic abortions were considered.

Anomalies of the fetal venous system: a report of 26 cases and review of the literature.

OBJECTIVE: To evaluate sonographic appearance, natural history, and neonatal outcome of fetal venous anomalies. METHODS: We performed an observational study, including all fetuses affected by abnormalities of the venous system diagnosed by ultrasound during the prenatal period. RESULTS: 26 fetuses were identified. Other malformations were present in 5 cases (19.2%), 1 fetus had trisomy 21, and 1 fetus had intrauterine growth retardation (IUGR). Twenty-five pregnancies ended in liveborn infants, and there was 1 case of unexplained intrauterine death in the fetus with IUGR affected by varix of the umbilical vein. CONCLUSIONS: Fetal venous anomalies are very rare and may be associated with fetal malformations or IUGR. Conservative management appears to be an adequate medical practice in the absence of other fetal problems, but in the presence of a varix of the umbilical vein, serial follow-up scans are needed to exclude the onset of hydrops or thrombosis of the varix.

[Correction of a dental and basal Class II with accentuated overjet using traction].

Correction of a dental and basal 2nd class with accentuated overjet using extraoral traction and programmed extractions of 17-27, 38-48 according to Armstrong's technique. The paper reports a case of dental and basal 2nd class with accentuated overjet treated using the extraction of 17-27, 38-48 and extraoral traction only, according to Armstrong's technique. Results obtained after 117 days of combined extraoral traction are reported in order to illustrate the reasons behind the choice of this apparatus and to demonstrate its evident efficacy in this case of 2nd class, 1st subdivision.

[Use of a functional appliance in initial orthodontic treatment of a case of dental and basal Class II with dental biprotrusion at age 12].

Use of functional plaque in the initial orthodontic treatment of a case of dental and basal 2nd class with dual dental protrusions in a 12-year-old patient. The use of a functional plaque is described in a 12-year-old male patient in dental and basal 2nd class, following the extraction of 1.6-2.5-2.6-3.6-4.6 due to caries. Biprotrusion was observed together with an overjet of 8 mm and an overbite of 6 mm. Results of the therapy are reported after 21 months.

[Results of triennial screening of a mountain community school population in USSL n. 42].

The paper reports data regarding dental caries in deciduous and permanent teeth in a sample population of 1015 pupils aged between 5 and 15, resident in the mountain community of the Chisone and Germanasca Valleys. The DMF index was significantly high, especially if one takes into account that the partial findings referring to '89 are virtually unchanged in comparison to '87.

[Different therapies in 2 cases of hyperdivergent monozygotic twins].

An interesting case of hyperdivergent homozygotic twins is examined. Both required dental treatment involving extractions: in one case of 15, 25, 35, 45 and in the other of 16, 26, 36, 46. The inherent problem is examined in the light of the extreme similarity of the twins.

[Possibility of cephalometric superimposition on a single point after Steiner, Ricketts and Cervera].

Following a brief introduction to the various methods of cephalometric superimposition proposed by different authors and school, the paper examines Cervera's system of cephalometric superimposition on a single point. The letter identified a single point, OcC point (Cervera's occlusal point), as the primary fulcrum from which to perform a correct cephalometric superimposition in order to examine the patient's anticipated growth. It is clear that initial anthropological interest, which was focused on the anterior cranial fossa, has gradually moved down to the lower third of the face, the anatomo-functional region in which the functions of the stomatognathic apparatus are mainly performed.
