Trichuris ovis and Trichuris globulosa: morphological, biometrical, and genetic studies

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.     

Cephalometric analysis of Rapp-Hodgkin syndrome

Rapp-Hodgkin syndrome (RHS) is a rare form of ectodermal dysplasia with variable involvement of the hair, eyes, sweat glands, nails, and teeth. Oral findings may include hypodontia, hypoplastic enamel, cleft lip/palate, and a pronounced midfacial hypoplasia. The objective of this study was to determine if the pronounced midfacial hypoplasia is the result of a true tissue hypoplasia or displacement of midfacial tissues. We have identified a family in which three members, a mother and two daughters, display clinical features characteristic of RHS. Clinical and intraoral examination of these affected persons showed manifestations characteristic of RHS, and several new findings were observed, including subcutaneous abscesses, palmoplantar keratosis, and keratotic lesions located on the chest and trunk. To assess the midfacial hypoplasia, lateral cephalometric analysis was performed on lateral headplates. Results of the cephalometric analysis suggest that the midfacial hypoplasia results from both a deficiency and a displacement of the maxilla. These findings are significant because successful dental treatment of RHS relies upon accurate assessment of current and projected orofacial development, particularly for the skeletal relations of the maxilla and mandible.     

A physiological approach to surgical treatment of progressive early idiopathic scoliosis

The Christ-Siemens-Touraine syndrome (CST syndrome) is the rare an- or hypohidrotic form of the ectodermal dysplasia. During embryonic development, the formation and maturation of the central nervous system and the epithelia of the sense organs, skin, teeth, hair (and less frequently the nails) are disturbed. In addition to the cosmetic impairment, insufficient or absent secretion of sweat and sebum is particularly discomforting as it leads to extreme heat intolerance. The decreased number of apocrine sweat glands and mucous glands in the upper nasopharynx results in diminished resistance to respiratory infections. We describe typical features of the disease in a 60 year old female patient, distinguishing this disease from other forms of ectodermal dysplasia. Diagnostic criteria as well as therapeutic options are discussed.     

The development of hepatic granulomas following interferon-alpha2b therapy for chronic hepatitis C infection

A patient with ectodermal dysplasia, Joubert's syndrome, and cerebral cysts is reported. The combination of these findings suggested a disorder of the embryonic ectoderm, manifesting as a neurocutaneous syndrome.     

Family with autosomal dominant hidrotic ectodermal dysplasia: a previously unrecognised syndrome?

We describe a three-generation family with an autosomal dominant hidrotic ectodermal dysplasia consisting mainly of tricho- and onychodysplasia. One of the patients had supraventricular tachycardia, another had palpitations, and two others had sinus brachycardia. We consider that the clinical manifestations in this family differ significantly from those of the Clouston syndrome (their previous diagnosis) and places them in Group A, subgroup 1-3 (tricho-onychic) of the ectodermal dysplasia classification proposed by Freire-Maia and Pinheiro [1988, "Ectodermal Dysplasias"].     

Hereditary congenital alacrima

We describe a family with markedly deficient lacrimation from infancy and punctate corneal epithelial erosions. An autosomal dominant inheritance pattern is suggested. A hypoplasia of the lacrimal gland in this family was suggested by pharmacologic testing and by histopathologic examination of the lacrimal gland of the proposita. The family investigated in this report represents the first instance of hereditary congenital alacrima without associated ocular or adnexal abnormalities and apart from systemic disorders such as the Riley-Day syndrome and anhidrotic ectodermal dysplasia.     

Two sibs with cleft palate, ankyloblepharon, alveolar synechiae, and ectodermal defects: a new recessive syndrome?

Hay and Wells in 1976 reported seven patients from four families who had an inherited condition of which the main features were ankyloblepharon, ectodermal defects, and cleft lip and palate. The inheritance pattern was determined to be autosomal dominant. This condition is known as AEC syndrome or Hay-Wells syndrome. We report a family with two sibs showing some of these features and congenital adhesions between the upper and lower jaws (alveolar synechiae). There seems to be a recessive pattern of inheritance as neither of the parents has any features of the syndrome. This could be described as a recessive form of Hay-Wells syndrome with additional features or be named as a new syndrome.     

A gene for autosomal dominant hypohidrotic ectodermal dysplasia (EDA3) maps to chromosome 2q11-q13

Autosomal dominant hypohidrotic ectodermal dysplasia (ADHED) is a disorder characterized by fine, slow-growing scalp and body hair, sparse eyebrows and eyelashes, decreased sweating, hypodontia, and nail anomalies. By genetic linkage analysis of a large ADHED kindred, we have mapped a gene for ADHED (EDA3) to the proximal long arm of chromosome 2 (q11-q13). Obligate recombinations localize EDA3 to an approximately 9-cM interval between D2S1321 and D2S308, with no apparent recombinations with markers D2S1343, D2S436, D2S293, D2S1894, D2S1784, D2S1890, D2S274, and CHLC.GAAT11C03.     

Ectodermal dysplasia: a review and case report

Ectodermal dysplasia is a hereditary disease characterized by a congenital dysplasia of one or more ectodermal structures and their accessory appendages. Common manifestations include defective hair follicles and eyebrows, frontal bossing with prominent supraorbital ridges, nasal bridge depression, and protuberant lips. Intraorally, common findings are anodontia or hypodontia, conical teeth, and, consequently, generalized spacing. The patient may suffer from dry skin, hyperthermia, and unexplained high fever as a result of the deficiency of sweat glands. The present review focuses on the clinical manifestations, classifications, and diagnosis of ectodermal dysplasia. A 6-year-old girl, described in the case report, exhibited many of the manifestations of ectodermal dysplasia as well as behavioral problems and a severe gag reflex. The treatment to improve her appearance and oral function included a removable prosthesis, acid-etch-retained indirect resin composite veneers, and a fixed partial denture.     

Prenatal diagnosis of a pancreatic cyst due to Ivemark II syndrome

We present a case of pancreatic cyst associated with other malformations which was diagnosed at antenatal ultrasound. Renal, hepatic, and pancreatic dysplasia as described by Ivemark in 1959 was confirmed by the pathology examination. This uncommon and lethal syndrome demonstrates autosomic recessive transmission. Ultrasound evidence of renal, hepatic and pancreatic dysplasia, associated with femoral abnormalities is suggestive of Meckel's syndrome. Other differential diagnoses are more easily distinguished (chondrodysplasia, chromosomal or metabolic abnormalities).     

Hidrotic ectodermal dysplasia in a black mother and daughter

Hidrotic ectodermal dysplasia is a rare genodermatosis with clinical hallmarks of alopecia, nail dystrophy, and palmoplantar hyperkeratosis. This report calls attention to the first reported cases, to our knowledge, of hidrotic ectodermal dysplasia in a black mother and daughter.     

Hair dysplasia in oculo-dento-digital syndrome. Apropos of a mother-daughter case

Oculo-dento-digital syndrome (SODD) as defined by Meyer-Schwickerath in 1957 is a rare entity (84 cases) which belongs to ectodermal dysplasias. It consists of: the characteristic features (long face, pinched nose); syndactyly; ocular, dental and bone abnormalities. This entity is usually transmitted on the autosomal dominant mode. We report two cases (a mother and daughter) with polymalformations which we classed as SODD. Furthermore, agenesis of lacrimal duct and genitourinary abnormalities were noted. The mother had a very particular complex hair shaft dysplasia (incomplete pili torti, "tiger tail" aspect, fractures) with alopecia since she was fifteen years old. The daughter's hair was normal at birth. In SODD, fine and sparse hair is often observed (44 p. 100). Only one patient had hair shaft investigation under polarized light: pili annulati and monilethrix were described but not found in our cases. These two reports incite to the systematic hair shaft study in SODD as other ectodermal dysplasia syndromes.     

Massive pulmonary hemorrhage in a patient treated with a platelet glycoprotein IIb/IIIa inhibitor

The authors describe an association of atrial septal defect with partial symptoms of the Poland-Moebius syndrome. Both are thought to be caused by developmental disorders of the mesenchyme and ectodermal derivatives. This anomalous association can be accepted as one concept of the subclavian artery blood supply disruption sequence during embryo-genesis.     

Preparation and characterization of freeze-dried chitosan-poly(ethylene oxide) hydrogels for site-specific antibiotic delivery in the stomach

Sotos syndrome is included among the overgrowth disorders, most of which have an increased risk of neoplasms. Sotos syndrome does not appear to be related to a specific tumor type, but rather to the development of solid tumors of ectodermal or mesodermal origin in general. We report on two Sotos syndrome patients who developed a non-Hodgkin lymphoma and an acute lymphoblastic leukaemia, respectively. Our experience suggests that there may exist a high frequency of lymphoproliferative disorders in Sotos syndrome, and points out the importance of a long-term follow-up of Sotos syndrome patients, to detect a possible neoplastic evolution.     

Painful tibial swelling in a young patient. Findings of radiology and radionuclide scanning. Anatomopathological correlation

An 11-year-old girl was diagnosed as having ectodermal dysplasia, with abnormalities of her nails, teeth, and hair noted from infancy. Her hair was unruly and investigations confirmed the changes seen in "cheveux incoiffables"-the uncombable hair syndrome. She also had atopy requiring treatment to control asthma and eczema. When she was 8 years old she developed vulval lichen sclerosus, which was controlled easily with early treatment. The coexistence of these conditions is discussed.     

Embryofetopathy due to valproate: a pathology only little known. Apropos of 4 cases

BACKGROUND: Sodium valproate administration during pregnancy may be teratogenic; it is associated with an increased risk of neural tube defect, tetralogy of Fallot, oral clefting and other facial abnormalities. Knowledge of these harmful effects is still poor. CASE REPORTS: Four children, including three siblings, presented with characteristic facial abnormalities (four cases), oral clefting (one case), mental retardation (2/2 cases), and bone anomalies of forearm and hands (one case). The diagnosis of fetal valproate syndrome was only made at the age of 3 1/2 years in the eldest of the three siblings all born from an epileptic mother receiving valproate since the age of 13 years. Prevention advice for further pregnancies was not followed. CONCLUSION: All epileptic mothers should be aware of the risk of antiepileptic drugs during pregnancy, specially those given sodium valproate, a potentially teratogenic drug.     

Pulmonary disorders in infants

Pulmonary disorders in infants are intimately related to the pulmonary development during the antenatal, neonatal and infantile period. In this review, normal pulmonary development is considered and several pulmonary disorders such as pulmonary hypoplasia, pulmonary sequestration, congenital cystic adenomatoid malformation, hyaline membrane disease, bronchopulmonary dysplasia, Wilson-Mikity syndrome and perinatal pneumonia are presented in light of the current literature.     

Hypohidrotic ectodermal dysplasia, central nervous system malformation, and distinct facial features: confirmation of a distinct entity?

Internal hydrocephalus with partial hypoplasia of the cerebellum was observed in a severely mentally retarded boy who showed signs of ectodermal dysplasia. Diagnostic considerations are discussed. Reports of the triad mental retardation-CNS malformation-ectodermal dysplasia are rare. In 1989 we reported a case with these signs that shows a striking facial similarity to the case presented here.     

Myth and reality in minimal access oncologic surgical management

A case of a woman affected by an unusual association of rare diseases, is presented. The patient was referred to our department for acute anaemia. Preoperative investigations revealed that the patient was affected by fibrous polyostotic dysplasia, so called Jaffè-Lichtenstein syndrome. The presence of skin brown spot and endocrine disorders requiring pill administration, allows to classify the patient as carrier of Albright syndrome. Moreover, the angiography pointed out a celiac trunc stenosis (Dunbar syndrome). The long-standing administration of the pill could be the cause of bleeding adenoma. The patient underwent hepatic resection. We did not treat the Dunbar syndrome because of poor symptoms. From literature, we review some opinions on the fibrous dysplasia of the bone.
