1/95. New case of the Richieri-Costa/Guion-Almeida syndrome.We describe a boy with multiple congenital anomalies/mental retardation (MCA/MR) syndrome. He has growth retardation, microbrachycephaly, coloboma of the iris, and typical facial anomalies including cleft lip/palate. This phenotype overlaps with that described by Richieri-Costa and Guion-Almeida in three Brazilian brothers. The new patient provides further evidence of the existence of this rare clinical entity.- - - - - - - - - - ranking = 1keywords = palate, cleft (Clic here for more details about this article) |
2/95. Evidence that AEC syndrome and Bowen--Armstrong syndrome are variable expressions of the same disease.Several clinical disorders combine ectodermal dysplasia (ED) and cleft lip and/or palate (CL/P). These conditions have been recognized as a group of diseases with a narrow phenotypic spectrum and multiple points of overlap. We report a patient with a clinical diagnosis of AEC syndrome (ankyloblepharon, ectodermal defects, and CL/P) who additionally has some features observed in a different ED-CL/P disorder, Bowen-Armstrong syndrome. Because of this clinical overlap, we suggest that AEC syndrome and Bowen-Armstrong syndrome may be variable manifestations of the same pathologic entity.- - - - - - - - - - ranking = 1keywords = palate, cleft (Clic here for more details about this article) |
3/95. Multiple systemic and periocular malformations associated with the fetal hydantoin syndrome.anticonvulsants remain necessary during pregnancy and the removal of such drugs is not recommended. However, on the available evidence, the physician may expect an increased risk of malformation including eye abnormalities as has been outlined. The abnormalities include growth deficiencies and delayed motor/mental development together with dysmorphic features, the most common of which seems to be cleft lip/cleft palate. Additionally, many of these children suffer from eye abnormalities including hypertelorism, ptosis, strabismus, epicanthal folds, and in this case abnormalities of the lacrimal apparatus.- - - - - - - - - - ranking = 7.0380325897794keywords = cleft palate, palate, cleft (Clic here for more details about this article) |
4/95. Rathke's cleft cyst as a cause of growth hormone deficiency and micropenis.Rathke's cleft cyst has rarely been reported in pediatric patients, and such cysts are usually found by chance, in 2-33% of routine necropsies, as they have not interfered with pituitary function. In general, they are intrasellar with a single layer of ciliated cuboidal or columnar epithelium containing mucoid material. The age range in which symptomatic Rathke's cleft cysts occur is between 30 and 60 years. This paper reports an 8.1-year-old boy presenting with growth hormone deficiency and micropenis attributable to hypogonadotropic hypogonadism (HH), implying altered pituitary function since intrauterine life. At this age (before puberty) the diagnosis of HH can be made by means of the LHRH agonist stimulation test, since conventional LHRH is not able to discriminate HH from a normal prepubertal child. To our knowledge, this is the first case of micropenis caused by Rathke's cleft cyst interfering with gonadotropin and growth hormone secretion since intrauterine life.- - - - - - - - - - ranking = 2.8716555971393keywords = cleft (Clic here for more details about this article) |
5/95. X-linked mental retardation syndrome with short stature, small hands and feet, seizures, cleft palate, and glaucoma is linked to Xq28.Of the gene-rich regions of the human genome, Xq28 is the most densely mapped. Mutations of genes in this band are responsible for 10 syndromal forms of mental retardation and 5 nonsyndromal forms. Clinical and molecular studies reported here add an additional syndromic form of X-linked mental retardation (XLMR) to this region. The condition comprises short stature, small hands and feet, seizures, cleft palate, and glaucoma. One affected male died at age 19 years in status epilepticus, but others have survived to old age. Carrier females do not have somatic anomalies or mental impairment. The gene is localized to the terminal 8 Mb of Xq28 with markers distal to DXS8011 showing linkage to the disorder with a lod score of 2.11 at zero recombination.- - - - - - - - - - ranking = 33.138980379512keywords = cleft palate, palate, cleft (Clic here for more details about this article) |
6/95. Two male patients with ring Y: definition of an interval in Yq contributing to turner syndrome.turner syndrome is thought to result from the haploinsufficiency of genes on the sex chromosomes, but these genes have not been identified yet. We describe two males with deleted ring Y chromosomes, one (TS) with full turner syndrome and one (DM) without. TS has short stature, skeletal anomalies, lymphogenic obstruction, cardiovascular abnormalities, and miscellaneous features including pigmented naevi, antimongoloid slanting of the palpebral fissures, and widely spaced nipples. In contrast, DM has short stature but no other specific Turner stigmata except high arched palate and a few pigmented naevi. Since little chromosomal mosaicism was detected, the different segments of the y chromosome retained by these two males identify the location of one or more "anti-Turner" genes. Most of the Yp pseudoautosomal region and Yq were deleted from both patients during the formation of the ring chromosome, while the Y specific portion of Yp and the centromere were retained. The major difference detected was an interval of proximal Yq present in DM and deleted in TS. None of the previously identified genes, DFFRY, DBY, UTY, or TB4Y, lies entirely within this interval, although DFFRY was truncated by DM's breakpoint. These data suggest that one or more additional "anti-Turner" gene(s) remains to be identified in the region of Yq proximal to DFFRY.- - - - - - - - - - ranking = 0.58976348612295keywords = palate (Clic here for more details about this article) |
7/95. Say syndrome: report of a familial case.We describe a new case of Say syndrome. This syndrome is an autosomal dominant condition characterized by cleft palate, short stature of prenatal onset, large protruding ears and microcephaly, delayed bone age, and renal anomalies. The first report was in 1975 by Say et al. in three generations of a family. Three additional reports of isolated cases were published. Our propositus is a 12-month-old boy with the cardinal signs of the syndrome whose mother has only microcephaly. To our knowledge this is the second familial report with evidence of highly variable expressivity. The occurrence of renal anomalies in a son of a normal sister of his mother suggests incomplete penetrance.- - - - - - - - - - ranking = 6.6277960759024keywords = cleft palate, palate, cleft (Clic here for more details about this article) |
8/95. Apparent cyclophosphamide (cytoxan) embryopathy: a distinct phenotype?cyclophosphamide (CP) is an alkylating agent widely used in treating cancer and autoimmune disease. CP is classified as a pregnancy risk factor D drug and is teratogenic in animals, but population studies have not conclusively demonstrated teratogenicity in humans. Six isolated reports of prenatally exposed infants with various congenital anomalies exist, but to date no specific phenotype has been delineated. The purpose of this report is to document a new case of in utero CP exposure with multiple congenital anomalies and to establish an apparent CP embryopathy phenotype. The mother had systemic lupus erythematosus and cyclophosphamide exposure in the first trimester. She also took nifedipine, atenolol, clonidine, prednisone, aspirin, and potassium chloride throughout pregnancy. The infant had growth retardation and multiple anomalies including microbrachycephaly, coronal craniosynostosis, hypotelorism, shallow orbits, proptosis, blepharophimosis, small, abnormal ears, unilateral preauricular pit, broad, flat nasal bridge, microstomia, high-arched palate, micrognathia, preaxial upper limb and postaxial lower limb defects consisting of hypoplastic thumbs, and bilateral absence of the 4th and 5th toes. Chromosomes were apparently normal. The reported cases of in utero exposure to cyclosposphamide shared the following manifestations with our patient: growth deficiency, developmental delay, craniosynostosis, blepharophimosis, flat nasal bridge, abnormal ears, and distal limb defects including hypoplastic thumbs and oligodactyly. We conclude that (a) cyclophosphamide is a human teratogen, (b) a distinct phenotype exists, and (c) the safety of CP in pregnancy is in serious question.- - - - - - - - - - ranking = 0.58976348612295keywords = palate (Clic here for more details about this article) |
9/95. Multiple congenital anomalies syndrome: growth and mental retardation, microcephaly, preauricular skin tags, cleft palate, camptodactyly, and distal limb anomalies. Report on two unrelated Brazilian patients.We report on 2 unrelated Brazilian patients, born to non-consanguineous parents, both with multiple anomalies including growth and mental retardation, microcephaly, telecanthus, cleft palate, preauricular skin tags/pit, camptodactyly, and foot anomalies. To our knowledge, this is a previously undescribed formal genesis syndrome. Clinical and genetic aspects are discussed.- - - - - - - - - - ranking = 33.138980379512keywords = cleft palate, palate, cleft (Clic here for more details about this article) |
10/95. Growth and developmental retardation, ocular ptosis, cardiac defect, and anal atresia: confirmation of the ROCA-Wiedemann syndrome.We report on a girl with growth and mental retardation, peculiar face with ptosis, epicanthus, broad nasal bridge, low-set and abnormal ears, cleft uvula, congenital heart defect, and anal atresia. A similar condition was reported previously by Wiedemann et al. [1982: An atlas of characteristic syndromes: a visual aid to diagnosis, 2nd ed. p 114-115]. We confirm the existence of this condition that, although similar to Ohdo syndrome, seems to be an independent clinical entity. We propose that, based on the principal clinical manifestations, this condition should be identified with the acronym ROCA (retardation of growth and development, ocular ptosis, cardiac defect, and anal atresia).- - - - - - - - - - ranking = 0.41023651387705keywords = cleft (Clic here for more details about this article) |
