11/931. Familial Evans syndrome: a report of an affected sibship.PURPOSE: This report describes the clinical course of three siblings, all of whom had Evans syndrome in childhood. patients: The coexistence of autoimmune hemolytic anemia and thrombocytopenia, in the absence of a known underlying cause, led to the diagnosis of Evans syndrome in a 4-month-old girl and subsequently in her two brothers when they were 4 and 13 years old. RESULTS: The 4-month-old girl had a life-threatening relapsing course unresponsive to corticosteroids, intravenous gamma-globulin, thymectomy, and cyclophosphamide. She eventually responded to splenectomy. Her two brothers had milder disease that responded to corticosteroids. Cytogenetic analyses revealed the presence of a familial Y;15 translocation in all three children and their father. CONCLUSION: There are few reported cases of familial Evans syndrome, and they are usually associated with an inherited congenital abnormality. We report the unusual finding of three siblings with the disease and no known congenital abnormality.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
12/931. Postanginal septicaemia with external jugular venous thrombosis: case report.Postanginal septicaemia is a syndrome of anaerobic septicaemia, septic thrombophlebitis of the internal jugular vein, and metastatic infections, that follows a localized infection in the area drained by the large cervical veins. The syndrome was well-known and often fatal in the preantibiotic era. It is now rather rare, presumably as a result of the almost routine use of prophylactic antibiotics. The symptoms are classic, and it should be suspected in any case where septicaemia and metastatic lesions are preceded by a head and neck infection. We report a case that is typical, except that branches of the external jugular vein were thrombosed. To our knowledge this has not been reported previously.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
13/931. Increased occurrence of cleft lip in glycogen storage disease type ii (GSDII): exclusion of a contiguous gene syndrome in two patients by presence of intragenic mutations including a novel nonsense mutation Gln58Stop.Genetic deficiency of lysosomal acid alpha-glucosidase (acid maltase) results in the autosomal recessive disorder glycogen storage disease type ii (GSDII) in which intralysosomal accumulation of glycogen primarily affects function of skeletal and cardiac muscle. During an earlier review we noted 3 in 100 cases of GSDII with incidental description of cleft lip. In addition, we identified 2 of 35 GSDII patients referred to us for molecular studies with co-occurence of cleft lip, considerably greater than the estimated frequency of nonsyndromic cleft lip with or without cleft palate of 1 in 700 to 1,000. Because several lines of evidence support a minor cleft lip/palate (Cl/P) locus on chromosome 17q close to the locus for GSDII, we defined the molecular basis for the GSDII in these two patients to determine if they represented a contiguous gene syndrome. Patient I (of Dutch descent) was homozygous and the parents heterozygous for an intragenic deletion of exon 18 (deltaex18), common in Dutch patients. Patient II was heterozygous for delta525T, a mutation also common in Dutch patients and a novel nonsense mutation (172 [corrected] C-->T; Gln58Stop) in exon 2, the first coding exon. The mother was heterozygous for the delta525T and the father for the 172 [corrected] C-->T; Gln58Stop. The finding that both patients carried intragenic mutations eliminates a contiguous gene syndrome. Whereas the presence of cleft lip/cleft palate in a patient with GSDII could be coincidental, these co-occurences could represent a modifying action of acid alpha-glucosidase deficiency on unlinked or linked genes that result in increased susceptibility for cleft lip.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
14/931. Fat embolism syndrome in a case of abdominal lipectomy with liposuction.Fat embolism syndrome is reported in a patient who underwent abdominoplasty and suction lipectomy for body contouring. Within 48 hours after surgery, she experienced adult respiratory distress syndrome, secondary to fat embolism syndrome. This was proven on bronchoscopy by evidence of fat laden macrophages. Aggressive respiratory support over 12 days resulted in patient survival.- - - - - - - - - - ranking = 2keywords = fat (Clic here for more details about this article) |
15/931. Miller-Dieker syndrome and trisomy 5p in a child carrying a derivative chromosome with a microdeletion in 17p13.3 telomeric to the LIS1 and the D17S379 loci.trisomy 5p and Miller-Dieker syndromes frequently are the result of unbalanced segregations of reciprocal translocations of chromosomes 5 and 17 with other autosomes. The critical regions for the expression of the mentioned syndromes have been mapped to 5p13-->pter, and 17p13.3-->pter. In this report, we describe an 8-year-old girl with mental retardation, postnatal growth deficiency, generalized muscular hypotonia, seizures, microcephaly, cortical atrophy, partial agenesis of corpus callosum, cerebral ventriculomegaly, facial anomalies, patent ductus arteriosus, pectus excavatum, long fingers, and bilateral talipes equinovarus caused by the presence of a 46,XX,der(17)t(5;17)(p13.1;p13.3)mat chromosome complement. Cytogenetic studies of the family confirmed a balanced reciprocal translocation (5;17)(p13.1;p13.3) in her mother, maternal grandfather, maternal aunt, and a female first cousin. fluorescence in situ hybridization studies on the mother and the proposita using three probes, which map to distal 17p, confirmed the reciprocal translocation in the mother and a terminal deletion in the patient, which resulted in the retention of LIS1 and D17S379 loci and deletion of the 17p telomere. These findings and the phenotype of the proposita, strongly suggest that genes telomeric to LIS1 and locus D17S379 are involved in many clinical findings, including the minor facial anomalies of the Miller-Dieker syndrome.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
16/931. Severe, non X-linked congenital microcephaly with absence of the pyramidal tracts in two siblings.In two siblings (a female and a male neonate), severe microcephaly, bilateral absence of the pyramids, severe hypoplasia of the cerebral peduncles, and dysplasia of the inferior olives was found together with microphthalmia, facial malformations and multiple contractures of the extremities. In both cases, the cerebral hemispheres otherwise showed a more or less normal gyral pattern with the insula incompletely covered by the opercula, and a tom but otherwise intact corpus callosum. In case 2, congenital cataract was also observed. The present cases can be characterized as a rapidly fatal, familial syndrome, probably transmitted as an autosomal recessive trait, and have several features in common with the Neu-Laxova syndrome. They differ in having a less severe form of microcephaly, a rather normal cytoarchitecture of the cerebral cortex, an apparently normal corpus callosum, no gross cerebellar abnormalities, and no other organ malformations. The present cases belong to a group of heterogeneous syndromes which have microcephaly, ocular and facial malformations, multiple contractures, and ichthyosis-like skin in common.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
17/931. Myopathy, myasthenic syndrome, and epidermolysis bullosa simplex due to plectin deficiency.plectin, an intermediate filament linking protein, is normally associated with the sarcolemma, nuclear membrane, and intermyofibrillar network in muscle, and with hemisdesmosomes in skin. A 20-year-old female with epidermolysis bullosa simplex since birth had progressive ocular, facial, limb, and trunkal weakness and fatigability since age 9, fivefold CK elevation, a 25% decrement with myopathic motor unit potentials and increased electrical irritability on electromyography, and no anti-acetylcholine receptor (AChR) antibodies. plectin expression was absent in muscle and severe plectin deficiency was noted in skin. Morphologic studies revealed necrotic and regenerating fibers and a wide spectrum of ultrastructural abnormalities: large accumulations of heterochromatic and lobulated nuclei, rare apoptotic nuclei, numerous cytoplasmic and few intranuclear nemaline rods, disarrayed myofibrils, thick-filament loss, vacuolar change, and pathologic alterations in membranous organelles. Many endplates (EPs) had an abnormal configuration with chains of small regions over the fiber surface and a few displayed focal degeneration of the junctional folds. The EP AChR content was normal. in vitro electrophysiologic studies showed normal quantal release by nerve impulse, small miniature EP potentials, and fetal as well as adult AChR channels at the EP. Our findings support the notion that plectin is essential for the structural integrity of muscle and skin, and for normal neuromuscular transmission.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
18/931. A male patient presenting with major clinical symptoms of glucocorticoid deficiency and skeletal dysplasia, showing a steroid pattern compatible with 17alpha-hydroxylase/17,20-lyase deficiency, but without obvious CYP17 gene mutations.We report the case of a 17-year-old boy with delayed puberty, who presented a complexity of clinical problems. An analysis of steroid hormones led to a diagnosis of 17alpha-hydroxylase/17,20-lyase deficiency (17OHD). Unlike typical cases of 17OHD, however, the patient had pubertal development without medical intervention. In addition, he never exhibited the symptoms of mineralocorticoid excess, showing instead the symptoms of glucocorticoid deficiency, including fatigability, emaciation, and weight-loss induced by minor infection. He also had dysmorphic features, which comprised marfanoid habitus, arachnodactyly and putative craniosynostosis. The combination of these malformations substantially resembled that of Shprintzen-Goldberg syndrome. Direct sequencing of the CYPl7 gene did not reveal any significant aberrations in the exons or exon-intron boundaries. We speculate that the association of partial combined 17OHD with the Shprintzen-Goldberg phenotype in the present patient may result from an aberration of a hitherto unknown gene that controls both steroid hormone synthesis and skeletal development.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
19/931. A case of paroxysmal tonic upgaze of childhood with ataxia.Paroxysmal tonic upgaze of childhood is a rare, distinctive, childhood syndrome that may be associated with ataxia and sometimes strabismus or amblyopia. Neurological examination as well as metabolic studies, electroencephalogram and neuroradiological investigations are normal in these patients. Although it has been considered as an age-related, dopa-sensitive dystonia, the exact pathogenetic mechanism is still unknown. Aggravation of attacks by fatigue, intercurrent infection or vaccination, and possible corticomesencephalic dysmaturation may underlie this abnormality. We report on a sporadic case of paroxysmal tonic upgaze with ataxia in which there was prompt aggravation of symptoms with sleep without response to levodopa treatment. This case suggests a different underlying pathogenetic mechanism from dopaminergic pathways for this syndrome.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
20/931. An infectious mononucleosis-like syndrome induced by minocycline: a third pattern of adverse drug reaction.A 22-year-old black man developed fever, chills, fatigue, night sweats, tender lymphadenopathy, and a generalized, pruritic, macular eruption 3 weeks after starting minocycline therapy for acne. His illness was also characterized by a palpable spleen tip, marked lower extremity and scrotal edema, and generalized lymphadenopathy. The patient had leukocytosis with a large percentage of atypical lymphocytes on peripheral smear and liver dysfunction. Titers for Epstein-Barr virus, hepatitis b, toxoplasmosis; and cytomegalovirus were all negative. Human immunodeficiency virus-1 viral load and antibodies were also negative. Marked improvement was noted after the discontinuation of minocycline and the use of systemic corticosteroids. With the negative viral serologies, the clinical picture was most consistent with an infectious mononucleosis-like syndrome produced by the minocycline ingestion.- - - - - - - - - - ranking = 1keywords = fat (Clic here for more details about this article) |
