Mitral and aortic valve replacement in a patient with ectodermal anhydrotic dysplasia. A case report.

Ectodermal anhydrotic dysplasia is a rare, usually X-linked recessive malformation of ectodermal tissues and organs. The case of a 17-year-old boy with ectodermal anhydrotic dysplasia and concomitant combined mitral valve disease and aortic insufficiency is described. The surgical risk was considered to be high due to severe atrophia of the laryngo-pharyngeal mucosa complicating endotracheal intubation and the possibility of postoperative temperature control disturbances. Double valve replacement was performed late in the autumn, after laryngo-pharyngeal pharmacological treatment preparing for endotracheal intubation. The peri-operative course was managed without any complication related to the hereditary malformation. Our experience suggests that patients suffering from ectodermal anhydrotic dysplasia may undergo open heart surgery after appropriate preparation. Potential postoperative problems related to the hypohydrosis and impaired spontaneous temperature control could be prevented in our patient.

Compound heterozygosity for new splice site mutations in the plakophilin 1 gene (PKP1) in a Chinese case of ectodermal dysplasia-skin fragility syndrome.

Ectodermal dysplasia-skin fragility syndrome is a rare autosomal recessive inherited disease characterized by skin fragility, nail dystrophy and hyperkeratosis of palms and soles. Skin biopsy shows the loss of cell adhesion and the decrease of desmosomes in number and size. Mutations in PKP1 have been found to be the underlying cause of the syndrome. We report here a Chinese case of ectodermal dysplasia-skin fragility syndrome. Mutation analysis revealed compound heterozygosity for mutations in PKP1 of the proband. A new splice site mutation (c.1053 T>A+c.1054+1 G>T) near the 3' end of exon 5 and at the donor end of intron 5 on one allele was transmitted from the proband's mother. Another new splice site mutation (c.1835-2 A>G) near the acceptor end of intron 10 originated from her father. The absence of the mutant mRNA and plakophilin 1 protein in the proband's skin may result from the mechanism of nonsense-mediated mRNA decay induced by premature stop codons in PKP1 transcripts due to the two splice site mutations.

Scalp dermatitis, distinctive hair abnormalities and atopic disease in the ectrodactyly-ectodermal dysplasia-clefting syndrome.

We report a 2-year-old girl with a combination of the ectodermal dysplasia, ectrodactyly, cleft lip/palate (EEC) syndrome, distinctive hair abnormalities, scalp dermatitis and atopic disease. To our knowledge, this is the first report of scalp dermatitis in the EEC syndrome. Distinctive structural hair abnormalities shared by the syndromes of ectodermal dysplasia and clefting are helicotrichia, pili torti et canaliculi, and cuticle defects, all of which were observed in the present case. A high incidence of atopic disease in certain subsets of ectodermal dysplasia has been reported. In our patient this manifested as food-induced exacerbation of atopic dermatitis, associated with positive prick tests and significant levels of circulating specific IgE.

Ectrodactyly-ectodermal dysplasia-clefting syndrome.

Ectrodactyly-ectodermal dysplasia-clefting syndrome is a rare congenital anomaly that affects tissues of mesodermal and ectodermal origin. Musculoskeletal involvement frequently requires orthopedic intervention. The authors present a review of the literature pertaining to this rare syndrome as well as a case report of a female patient who exhibited the complete clinical triad. A description of the surgical management of her condition is also presented.

The ectrodactyly-ectodermal dysplasia-clefting syndrome: a literature review and case report.

Ectrodactyly, atypical anhidrotic ectodermal dysplasia, and cleft lip and palate are the principal manifestations of ectrodactyly-ectodermal dysplasia-clefting syndrome. Intraorally, the common manifestations of the syndrome are hypodontia, enamel hypoplasia, and generalized microdontia. In addition, the patient may suffer from xerostomia and have a deeply fissured tongue. The oral mucosa appears, in some patients, to have an increased susceptibility to candidiasis. This case report describes a patient who exhibits many of the manifestations of the syndrome and explains ways in which many of the anomalies of the dentition can be esthetically and functionally corrected.

Clinical and scanning electron microscopic findings in a solitary case of Trichorhinophalangeal syndrome type I.

A solitary case of Trichorhinophalangeal syndrome type I is described. Scanning electron microscopic examination revealed alterations of the cuticular pattern and hair shaft structure. These alterations have not been previously described and differ from those seen in other syndromes belonging to the group of the ectodermal dysplasias e.g. the Trichoonytic Hidrotic ectodermal dysplasia, autosomal recessive Anhidrotic ectodermal dysplasia and X-linked Anhidrotic ectodermal dysplasia.

Normal immunological status in four patients with ectrodactyly-ectodermal dysplasia-clefting syndrome (EEC-syndrome).

Lobster-claw deformity of the extremities, clefting of the primary and secondary palate, ectodermal dysplasia, and atresia of the lacrimal system are common features of the ectrodactyly-ectodermal dysplasia-clefting syndrome (EEC-syndrome). The patients often suffer from repeated infections of eyes, upper respiratory tract and urogenital system. To exclude an immunodeficiency as cause of the infectious predisposition in patients with EEC-syndrome, we screened the immunosystem in four related patients with EEC-syndrome. All patients were found to present normal immunoglobulin production, complement activity, lymphocyte-, and granulocyte function. We conclude that recurrent infections observed in the EEC-syndrome are not caused by an immunological defect, but seem to result solely from anatomical anomalies.

P63 gene mutations and human developmental syndromes.

The P63 gene is a recently discovered member of the p53 family. While P53 is ubiquitously expressed, p63 is expressed specifically in embryonic ectoderm and in the basal regenerative layers of epithelial tissues in the adult. Complete abrogation of P63 gene function in an animal model points to the relevance of P63 for the proper development of ectodermally derived tissues. The p63 knockout mouse dies at birth and has truncation of the limbs, as well as absence of epidermis, prostate, breast, and urothelial tissues, apparently reflecting ectodermal stem cell loss. A number of dominant human syndromes have been mapped to chromosome 3q27 and ultimately to mutations in the p63 gene. These syndromes have abnormal limb development and/or ectodermal dysplasia and include ectrodactyly, ectodermal dysplasia, clefting syndrome; ankyloblepharon, ectodermal dysplasia, clefting syndrome; acro-dermato-ungual-lacrimal-tooth syndrome; limb-mammary syndrome; as well as nonsyndromic split hand/foot malformation. The pattern of heterozygous mutations is distinct for each of these syndromes. Consistent with this syndrome-specific mutational pattern, the functional consequences of mutations on the p63 proteins also vary, invoking dominant-negative and gain-of-function mechanisms rather than a simple loss of function.

Ectrodactyly-ectodermal dysplasia-clefting syndrome (EEC): report of a case with perioral papillomatosis.

We report a 13-year-old boy with ectodermal dysplasia, ectrodactyly, and syndactyly, hypospadias, photophobia, conductive hearing loss, and perioral papillomatosis. His father had ectrodactyly and hypotrichosis. The clinical picture suggested ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome. The presence of perioral papillomatosis, classically seen in Goltz syndrome, has been reported only once before in EEC syndrome.

[Neurogenic hypernatremia with adipsia and cerebral malformations in a child with ectrodactyly-ectodermal dysplasia-cleft lip-palate syndrome].

An infant with E.E.C. Syndrome (a genetic condition characterized by: Ectrodactyly, Ectodermal dysplasia, Cleft Lip-Palate) and delayed psychomotor development was found to have chronic hypernatremia and absence of thirst. Computerized brain tomography revealed abnormal lateral ventricles, agenesis of corpus callosum, calcified cortex. His plasma Anti Diuretic Hormone (ADH) levels were inappropriately low relative to his high values of plasma osmolality, whereas ADH responsiveness to nonosmotic stimuli was normal. E.E.C. Syndrome in this baby is characterized by: ectrodactyly of the feet, syndactyly of the 3rd and 4th finger of the hands, bilateral cleft lip and cleft palate, bilateral microtia, lacrimal ductular stenosis. To our knowledge, this is the first report of a case of chronic hypernatremia in conjunction with normal ADH stores, congenital abnormalities of brain structures, and E.E.C. syndrome.

Pierre Robin sequence in a patient with ectrodactyly-ectodermal dysplasia-clefting syndrome: a case report and review of the literature.

Ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome is a rare condition first identified in 1970. The majority of cases are reported to be autosomal dominant with variable expression and penetrance. The most common clinical feature is ectodermal dysplasia. Ectrodactyly, cleft lip with or with out cleft palate and urogenital anomalies are also main clinical features of EEC syndrome. Pierre Robin (PR) sequence has the clinical findings of micro-retrognathia, retroposed tongue (glossoptosis), cleft of the secondary palate, and upper airway obstruction. Etiologically PR sequence is heterogeneous. It has been reported that less than 20% of cases are isolated, non-syndromic PR sequence. We present a case of a newborn male who was referred to our craniofacial clinic with EEC syndrome and PR sequence. This case represents a unique clinical association. We found no other reports in the literature of these two clinical entities occurring together. Upper airway obstruction of PR sequence, secondary to glossoptosis and micro-retrognathia, gives this association clinical relevance. In addition, this clinical association may represent a new gene locus associated with EEC syndrome.
