Limb deficiency with or without Möbius sequence in seven Brazilian children associated with misoprostol use in the first trimester of pregnancy.

Misoprostol, a synthetic analog of prostaglandin, has been widely used in Brazil as an abortifacient. Abortion is illegal in Brazil. An uncertain number of these abortion attempts are unsuccessful and the pregnancy continues. We report on 7 patients whose mothers attempted to abort using this drug in the first trimester of gestation without success. The 7 patients presented with limb defects and in 4 of them a diagnosis of Möbius sequence was made.

A patient with tetrasomy 9p, Dandy-Walker cyst and Hirschsprung disease.

The authors report on a patient with tetrasomy 9p and 9qh due a karyotype 47,XY,+dic(9)(q12) in lymphocytes and a normal karyotype in fibroblasts. Clinical and complementary investigation revealed a malformation syndrome with many anomalies like those of trisomy 9p as well as Dandy-Walker cyst and Hirschsprung disease not previously described in tetrasomy 9p.

Chromosome abnormalities in selected newborn infants with malformations in Brazil.

Between 1982 and 1985, 109 infants were referred for cytogenetic examination out of a population of 73,192 liveborn infants from eight maternity hospitals surveyed by the ECLAMC/MONITOR program. Thirty-one of the children had a chromosome abnormality different from trisomy 21. Considering the total population surveyed, trisomy 18 was detected in 1:6,099; trisomy 13 was seen in 1:24,397 and unbalanced rearrangements were found in 1:7,319 infants. Those rates were not significantly different from the expected ones, as compared to previous cytogenetic surveys of consecutive births. We concluded that most chromosome abnormalities associated with congenital malformations can be detected at low cost, provided there is a high accuracy of clinical examination and referral criteria, as well as close cooperation between pediatricians and geneticists.

Terminal deletion 1q43 in a newborn with hydrocephalus.

A male newborn presented the main craniofacial features of the 1q terminal syndrome: prominent metopic sutures, flat nose bridge, wide short nose with anteverted nares, epicantus, telecanthus, long philtrum, thin upper lip with a well defined cupid bow, downturned corners of the mouth, retrognathia. The child also had an aqueductal obstructive hydrocephalus.

Duchenne muscular dystrophy in a girl with an (X;15) translocation.

This is a report of a girl with Duchenne muscular dystrophy (DMD) associated with an 46,X,t (X;15) (p21; q 26) chromosome constitution. Although in the eight published cases of girls with DMD and a t(X;aut) different autosomes were involved in the translocation, the breakpoint was always at Xp21. The present case supports the hypothesis that the DMD gene must be located at Xp21. In this study, involvement of the father's chromosomes in the translocation was detected.

Pregnancy outcome after exposure to misoprostol in Brazil: a prospective, controlled study.

BACKGROUND: Misoprostol, a synthetic prostaglandin E1 analog is labeled for the treatment of gastric and duodenal ulcers. In Brazil, where abortion is not a legal procedure, there is a widespread popular misuse of this drug in abortion attempts. This misuse and the fact that, in many cases the desired pregnancy termination does not occur, raise concerns about fetal safety. Case reports of congenital anomalies after maternal use of misoprostol have been published. The objective of this work was to compare pregnancy outcome following misoprostol exposure with a matched control group. This is the first prospective controlled study on fetal safety after misoprostol use. METHODS: A prospective, observational cohort study with 86 exposed and 86 pair-matched, non-exposed controls. RESULTS: There was no significant difference in the rates of major or minor birth between exposed compared to non-exposed infants (2/67 vs 2/81, major defects; 7/67 vs. 3/81, minor anomalies) There were significantly more miscarriages in the exposed group (17.1% vs. 5.8%; relative risk, 2.97; 95% confidence interval, 1.12 to 7.88). There was no statistical difference in gestational age at delivery, birth weight, sex ratio, rate of prematurity, low birth weight, or rates of cesarean section between groups. CONCLUSIONS: Our study, despite its limited statistical power, does not suggest a potent teratogenic action of misoprostol exposure during pregnancy.

Ocular and clinical manifestations of Möbius' syndrome.

PURPOSE: To assess ocular and otorhinolaryngologic manifestations and intellectual ability in patients with Möbius' syndrome. METHODS: Patients with Möbius' syndrome underwent prospective ophthalmic, genetic-clinical, and otorhinolaryngologic examinations as well as psychological evaluation. RESULTS: Sixteen patients with Möbius' syndrome between the ages of 8 months and 10.6 years underwent ocular examination. Esotropia was present in 12 (75%) patients and V-pattern in 8 (50%). Limited abduction was present in 30 (93.8%) eyes, and limited adduction was present in 21 (65.6%) eyes. The most frequent refractive error was compound hyperopic astigmatism (13 [40.6%] eyes). Eleven (68.8%) patients had lagophthalmos and 12 (75%) patients had bilateral epicanthus. Unilateral amblyopia was present in 2 (12.5%) patients. Clubfoot was the most common lower limb defect (7 [43.8%] patients). Cranial nerve impairments included paralysis of 7th nerve in all patients, paralysis of the 12th nerve in 13 patients, and paralysis of the 9th and 10th nerves in 3 patients. Evaluation of intellectual ability showed that 4 (25%) patients had normal intelligence. The mothers of 3 (18.8%) patients used misoprostol during the first trimester of pregnancy. CONCLUSION: Prominent ophthalmic features of Möbius' syndrome in this series were esotropia, V-pattern, abduction limitation, and compound hyperopic astigmatism. Intellectual assessment showed some degree of mental retardation in 75% of patients. Möbius' syndrome is associated with prenatal exposure to misoprostol.

Perinatal factors associated with neural tube defects (anencephaly [correction of anancephaly], spina bifida and encephalocele).

The objective of the present study was to determine the presence of risk factors for the occurrence of neural tube defects. Data for 33,535 births which occurred at Hospital do Servidor Público Estadual de São Paulo from July 1973 to December 1986 were collected in a prospective manner as recommended by "Estudo Colaborativo Latino-Americano de Malformações Congênitas" (ECLAMC, Collaborative Latin American Study on Congenital Malformations). Twenty-six cases of neural tube defects were detected (0.77/1000 births). Of these, 11 were cases of spina bifida (0.39/1000 births), 9 of anencephaly (0.27/1000 births) and 6 of encephalocele (0.18/1000 births). We observed a higher frequency of polyhydramnios, premature labor, Apgar scores of less than 7 at the first and fifth minutes, low birth weight and intrauterine growth retardation.
