Acheiropodia: report on four new Brazilian patients.

We report on 4 new patients with acheiropodia ("the handless and footless families of Brazil"). This autosomal recessive condition involves all 4 limbs with a well-defined pattern of defects. Two of the patients described here had a small bone fragment in the upper stumps (Bohomoletz bone), an uncommon finding in acheiropodia.

Possible common pathogenetic mechanisms for Poland sequence and Adams-Oliver syndrome.

We report on 2 families having members affected with the Poland sequence and Adams-Oliver syndrome. In the first family, a 5-month-old boy presented with Adams-Oliver syndrome; his mother had Poland sequence. In the second family, a 12-year-old boy and his mother presented with findings suggestive of Adams-Oliver syndrome and Poland sequence. This suggests that the same genetic predisposition may result in either or both conditions.

Ectrodactyly, cleft lip/palate syndrome.

We report on a Brazilian boy with ectrodactyly, cleft lip/palate, and abnormal pinnae. The clinical aspects involving this patient strongly suggest those reported by Lewis and Pashayan in 1981. Clinical and genetic aspects are discussed.

Adams-Oliver syndrome revisited.

The occurrence of Adams-Oliver syndrome in a patient from the same geographic area as the first reported kindred led to follow-up of the original family, and to a survey of the literature. Of 81 cases in 32 families, there is an approximately equal distribution between sexes (38 males: 43 females). Vertical transmission in at least 8 families is consistent with autosomal dominant inheritance. The phenotype is variable with a range of mild-to-severe defects of the scalp and/or underlying bone. Despite large defects of the cranium, central nervous system abnormalities have not been found and intellectual development appears to be normal. Limb defects are usually limited to the digits, but may involve the long bones and are entirely absent in some obligate carriers of the gene. Cutis marmorata and tortuous, dilated scalp veins have been reported in association with the major head and limb defects, but also in isolation as a forme fruste phenotype. Thus, there is a broad range of variable expression ranging from cases with lethally hemorrhagic cranial defects and/or severe limb malformations, to patients without any apparent manifestations. Despite a phenotypic resemblance to isolated aplasia cutis congenita and to the syndrome of terminal transverse limb defects, Adams-Oliver syndrome appears to be causally distinct. While the underlying pathophysiologic mechanism remains unknown, it can be speculated that cranial vertex defects and malformations of the limbs represent field defects resulting from impaired circulation in "watershed" areas during a critical period of development.

Costello syndrome.

In 1971, Costello described a new syndrome in 2 patients. The major clinical findings comprise short stature; redundant skin of the neck, palms, soles, and fingers; curly hair; relative macrocephaly; depressed nasal bridge; papillomata around the mouth and nares; distinct facial gestalt; hyperextensible joints; and mental retardation. We present a third patient and review the manifestations of this condition.

Apparent Greig cephalopolysyndactyly and sinus node disease.

We present the clinical findings and follow-up data from birth to 10.5 years in a boy with Greig cephalopolysyndactyly who, in addition, presents sinus node disease ("sick sinus syndrome"). The significance of the concurrence of Greig cephalopolysyndactyly syndrome, an autosomal dominant condition mapped at 7p13, and sinus node disease is discussed.

Congenital defects of the limbs in stillbirths: data from a population-based study.

We analyzed limb deficiencies occurring in stillbirths with congenital anomalies registered in the Health Surveillance Registry of British Columbia between the years 1964 and 1984. Thirty stillborn infants presenting with various defects of the limbs were found during this time, giving an incidence of 39.52 in 10,000 stillbirths (1:253). This incidence is significantly higher than the incidence among liveborn individuals in the Province (5.97 in 10,000 livebirths or 1:1,842). Most cases involved the upper limbs, and most frequently the radius. Additional anomalies were present in 77% of cases, compared to 48% in liveborns. The study of stillbirths with congenital anomalies provides important information regarding the spectrum of birth defects seen in this group. This may be of relevance because of improved survival possibilities due to advances in perinatal care.

Amniotic band sequence and limb defects: data from a population-based study.

Cases with amniotic bands were analysed separately as part of an ongoing study of limb defects occurring among 1,213,913 liveborn infants in British Columbia during the years 1952 to 1984. A total of 24 cases with this specific condition was identified among 659 cases with limb defects. The calculated incidence for amniotic band sequence with significant limb involvement was 0.19 in 10,000 livebirths. This is a minimal incidence, as cases without defects of the limbs, but with constriction rings were not identified with this approach. Familial cases and cases with additional anomalies were found.

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.

Poland anomaly with unusual associated anomalies: case report of an apparent disorganized defect.

We report on a 2 1/2-year-old boy with absence of clavicular head of pectoralis major on the left side, ipsilateral upper limb anomalies, and anomalies of the lower limbs such as popliteal webbing, median cleft of right foot, bifid left hallux, syndactyly of toes, and toenail hypoplasia. Other anomalies included undescended testis, hairy nevus in the lumbosacral region, and a pedunculated finger-like tag on the right thigh. The pathogenesis of these associated anomalies cannot be explained on the basis of compromised local blood supply alone. A possible link with the disorganization mutation is discussed.

Absent pituitary gland in two brothers with an oral-facial-digital syndrome resembling OFDS II and VI: a new type of OFDS?

The oral-facial-digital syndromes (OFDS) comprise a group of heterogeneous genetic disorders. Considerable clinical overlap exists within the nine described types [Toriello, Clin Dysmorph 2:95-105, 1993], and with other entities such as Pallister-Hall (PH) syndrome and hydrolethalus syndrome, leading to difficulties in the classification of OFDS. We report on two brothers with findings overlapping OFDS II, VI, and Pallister-Hall syndrome who had congenital absence of the pituitary gland. This may represent a new type of OFDS or, alternatively, an example of phenotypic variability within the OFDS. It also emphasizes that agenesis of the pituitary gland can occur in a variety of syndromes with midline defects.

Probable new syndrome in a Mexican family with congenital palmar polyonychia and postaxial limb defects.

Congenital palmar polyonychia (CPP) is a rare and usually sporadic birth defect. We report on a Mexican girl with CPP of both 5th fingers and her sister with ectrodactyly with ulnar ray deficits and agenesis of the ulna. In previous reports, CPP has been seen in ectrodactyly with involvement of the ulna and ulnar digital rays and with postaxial polydactyly. Such findings observed in our patients can be considered a form of CPP. Autosomal dominant inheritance of CPP is more likely based in previous informative families with vertical transmission and instances of male-to-male transmission. The present and two previous families with affected sibs only may represent parental gonadal mosaicism, whereas de novo mutation or incomplete evaluation of relatives could be an explanation for sporadic cases. Variable expression of the CPP phenotype may be a new autosomal dominant entity, i.e., a CPP-postaxial limb defect syndrome.
