1/931. Variable clinical expression of Holt-Oram syndrome in three generations.Holt-Oram syndrome is a distinct autosomal dominant entity presenting with upper limb defects and cardiac abnormality. No correlation between the severity of the heart and the limb defects has been established. Here we report variable clinical expression of Holt-Oram syndrome in three generations. The grandfather presented with typical upper limb defects: phocomelia of arms with three digits on each hand, congenital heart defect and narrow shoulders. His son manifested cardiac conduction disturbance with no congenital heart or skeletal defect. The granddaughter showed ventricular septal defect and moderate radial deviations of both hands with no obvious hypoplasia of the extremities. Clinical data of the presented family suggests lack of penetrance with respect to skeletal and structural cardiac abnormalities in the Holt-Oram syndrome.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
2/931. Partial lipodystrophy presenting with myopathy.A girl with partial lipodystrophy is described presenting with muscle weakness and developmental delay several years before lipoatrophy became apparent. The patient subsequently developed epilepsy, fatty liver, secondary amenorrhoea, hirsutism, insulin-resistant diabetes mellitus, hyperlipidaemia, and hypothyroidism. She remains weak with poor exercise tolerance. This case illustrates an atypical presentation of the Barraquer-Simon syndrome.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
3/931. birt-hogg-dube syndrome and Hornstein-Knickenberg syndrome are the same. Different sectioning technique as the cause of different histology.The autosomal dominant inherited syndromes of Hornstein and Knickenberg (HKS), and Birt, Hogg and Dube (BHDS) are both characterized clinically by the overall spread of multiple flesh coloured papules of the skin. However, it is a matter of debate if colonic neoplasms (adenomas as well as adenocarcinomas) are associated findings in the HKS or rather in the BHDS. Furthermore, histological differences are said to exist between the skin lesions in the two syndromes: whereas perifollicular fibromas were described in the HKS, fibrofolliculomas and trichodiscomas were found in the BHDS. In the present study, we report on a father and his daughter in whom we initially diagnosed a BHDS. We then examined a greater number of the papular lesions in histologic sections cut vertically as well as horizontally to the epidermis. Our results indicate that the histologic differences between the skin lesions in the two syndromes are artificial ones, caused by interpretation of different sectioning planes, and that consequently HKS and BHDS are the same. Therefore, it is necessary to look for colonic polyps in the syndrome in question, regardless if one prefers the name HKS or BHDS for it.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
4/931. A syndrome of congenital ichthyosis, hypogonadism, small stature, facial dysmorphism, scoliosis and myogenic dystrophy.Rud syndrome formerly was considered as a genetically heterogeneous but distinct clinical entity with the manifestations of ichtyosis, hypogonadism, small stature, mental retardation, epilepsy and, infrequently, retinitis pigmentosa. The existence of such a syndrome has recently been dismissed based on a new understanding of the ichthyoses. We report on the clinical history of a 14-year-old boy with congenital ichthyosis, small stature, hypogonadism, facial dysmorphism, nystagmus, kypho-scoliosis and myogenic dystrophy. He was diagnosed as Rud syndrome but developed neither seizures nor mental retardation. However a cousin was mentally retarded. The ichthyosis was familial as five relatives had ichthyosis but no other features of Rud syndrome. The patient had a deletion of the steroid-sulfatase gene. He had neither chondrodysplasia punctata, nor kallmann syndrome, two conditions which are part of the contiguous gene syndrome of the Xp22.3 region. Most case reports previously reported as Rud syndrome can now be reassigned under a contemporary ichthyosis classification that does not include Rud syndrome as a distinct entity. This case was clearly distinct from refsum disease, sjogren-larsson syndrome and any of the other ichthyosis disorders that have been suggested as a replacement for Rud syndrome. Thus the case reported here appears distinct from any previously described, currently recognized syndrome.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
5/931. Defective glucose transport across brain tissue barriers: a newly recognized neurological syndrome.Impaired glucose transport across brain tissue barriers causes infantile seizures, developmental delay and acquired microcephaly. Since the first report in 1991 (De Vivo et al, NEJM, 1991) 17 patients have been identified with the glucose transporter protein syndrome (GTPS). The diagnostic feature of the syndrome is an unexplained hypoglycorrhachia in the clinical setting of an infantile epileptic encephalopathy. We review our clinical experience by highlighting one illustrative case: a 6-year old girl who presented at age 2 months with infantile seizures and hypoglycorrhachia. The CSF/blood glucose ratio was 0.33. dna sequencing identified a missense mutation in exon 7 (C1108T). Erythrocyte GLUT1 immunoreactivity was normal. The time course of 3-O-methyl-glucose (3OMG) uptake by erythrocytes of the patient was 46% that of mother and father. The apparent Km was similar in all cases (2-4 mmol/L), but the apparent Vmax in the patient was only 28% that of the parents (500 versus 1,766 fmol/s/10(6)RBC; p < 0.004). In addition, a 3-month trial of oral thioctic acid also benefited the patient and increased the Vmax to 935 fmol/s/10(6) RBC (p < 3 x 10(-7)). Uptake of dehydroascorbic acid by erythrocytes of the patient was impaired to the same degree as that of 3OMG (Vmax was 38% of that of the mother's), which supports previous observations of GLUT1 being multifunctional. These studies confirm the molecular basis of the GTPS and the multifunctional role of GLUT1. The need for more effective treatment is compelling.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
6/931. Leri-Weill syndrome as part of a contiguous gene syndrome at Xp22.3.We report on a mother and her 5-year old son, both with a terminal deletion of the short arm of the x chromosome. By molecular genetic analysis the breakpoint was located distal to steroid sulfatase gene. The boy manifested, due to nullisomy of this region, short stature (SHOX), chondrodysplasia punctata (ARSE), and mental retardation (putative mental retardation gene MRX 49). Short stature is present in mother and son, but both also had bilateral Madelung deformity, a key finding in the Leri-Weill syndrome.We discuss the phenotype in relationship to hitherto published cases with chromosomal aberrations and contiguous gene syndromes of Xp22.3.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
7/931. A female case of Kallmann's syndrome.A case of 20-year-old woman with hypogonadotropic hypogonadism and anosmia is reported, since very few female cases of Kallmann's syndrome have been reported so far in japan. Three uncles on the father's side had no children. Height was 168 cm, and arm span 165 cm. The olfactory test revealed complete anosmia. Bone age was 13 year. Chromosome was 46 XX and normal karyotype. Basal levels of serum FSH, LH and estrogens (E1, E2 and E3) were low. serum FSH and LH levels rose slightly only after LH-RH administration, and did not increase in clomiphene test. plasma estrogens did not increase after daily injection of 150 IU of HMG for 3 successive days. The response of serum GH to arginine infusion was normal, while that to insulin-induced hypoglycemia was poor.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
8/931. A Rapp-Hodgkin like syndrome in three sibs: clinical, dental and dermatoglyphic study.Rapp-Hodgkin ectodermal dysplasia is an autosomal dominant disorder characterized by distinctive craniofacies, cleft lip or palate, oligodontia or anodontia, hypoplasia of the nails, and a decrease in or absence of the sweat glands and hair follicles. We have identified a family in which three children display clinical features similar to Rapp-Hodgkin syndrome. The father and two other sisters of the patient had normal facial features, but had short stature and had dental anomalies, the latter suggestive of ectodermal dysplasia. The overall clinical, dental, and dermatoglyphic findings of these patients are discussed in relation to reports of families with Rapp-Hodgkin syndrome.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
9/931. dialysis encephalopathy: a possible seizure disorder.dialysis encephalopathy is a progressive, fatal condition that occurs in patients receiving hemodialysis. It is characterized by abnormalities in speech, myoclonic jerks, and striking changes on the electroencephalogram. We observed dramatic reversal of the clinical symptoms and electroencephalographic abnormalities in four patients with this syndrome who were treated with diazepam. In this paper we propose that in dialysis encephalopathy, some of the symptoms and the electroencephalographic changes represent a form of seizure disorder.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
10/931. The wide spectrum of clinical expression in Adams-Oliver syndrome: a report of two cases.Two children are described with the combination of aplasia cutis congenita (ACC) and transverse limb defects known as Adams-Oliver syndrome. Whereas in the first child the typical features of ACC, syndactyly and transverse nail dystrophy were only mildly expressed and associated defects of the central nervous system and cardiac malformations were absent, the second child suffered from a very severe expression of the syndrome, with a combination of ACC, syndactyly, cutis marmorata telangiectatica congenita and multiple cardiac and central nervous system malformations which resulted in fatal central respiratory insufficiency.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
