Amiodarone has proved to be a valuable drug in atrial fibrillation associated with the Wolff-Parkinson-White syndrome. When it was administered to a patient with this syndrome in atrial fibrillation, who had previously suffered an inferior myocardial infarction, the ventricular rate accelerated from 170 to 230 beats/minute.This unusual case emphasises the need for full electrophysiological assessment of patients with the Wolff-Parkinson-White syndrome for whom amiodarone treatment is being considered. 相似文献

Ehlers-Danlos syndrome is an inherited collagen disorder characterized by skin hyperextensibility, joint laxity, and tissue friability. In this study, it was hypothesized that Ehlers-Danlos syndrome is frequently undiagnosed in patients who present for repair of ventral abdominal wall hernias. A retrospective chart review was conducted, and patients who had presented for elective repair of recurrent abdominal wall herniation were identified. In all patients, one or more prior attempts at repair with either mesh or autologous tissues had failed. Patients in whom abdominal wall components were lost secondary to extirpation or trauma, patients who had required acute closure, and patients with less than 2 months of follow-up were excluded. Twenty patients met these criteria. Twenty cases of recurrent ventral hernia repairs were reviewed, with special attention to identification of the preoperative diagnosis of Ehlers-Danlos syndrome. Patients ranged in age from 29 to 75 years, with a mean age of 54 years. Five patients were male (25 percent), and 15 were female (75 percent). The majority (95 percent) were Caucasian. The most common initial procedures were gynecologic in origin (35 percent). A precise closure technique that minimizes recurrence after ventral hernia repairs was used. With use of this technique, there was only one recurrence over a follow-up period that ranged from 2 to 60 months (mean follow-up duration, 25.7 months). Two patients with Ehlers-Danlos syndrome were identified, and their cases are presented in this article. The "components separation" technique with primary component approximation and mesh overlay was used for defect closure in the two cases presented. The identification of these two patients suggests the possibility of underdiagnosis of Ehlers-Danlos syndrome among patients who undergo repeated ventral hernia repair and who have had previous adverse postoperative outcomes. There are no previous reports in the literature that address recurrent ventral abdominal herniation in patients with Ehlers-Danlos syndrome. 相似文献

Coexistent Brugada syndrome and Wolff-Parkinson-White (WPW) syndrome is rare, and as such poses management challenges. The overlap of symptoms attributable to each condition, the timing of ventricular stimulation after accessory pathway ablation and the predictive value of programmed stimulation in Brugada syndrome are controversial. We describe a case of coexistent Brugada syndrome and WPW syndrome in a symptomatic young adult. We discuss our treatment approach and the existing literature along with the challenges in management of such cases. 相似文献

Primary ciliary dyskinesia (PCD) is a multisystem disease characterized by recurrent respiratory tract infections, sinusitis, bronchiectasis and male subfertility, associated in about 50% patients with situs inversus totalis (the Kartagener syndrome). The disease phenotype is caused by ultrastructural defects of respiratory cilia and sperm tails. PCD is a heterogenetic disorder, usually inherited as an autosomal recessive trait. So far, mutations in two human genes have been proved to cause the disease. However, the pathogenetics of most PCD cases remains unsolved. In this review, the disease pathomechanism is discussed along with the genes that are or may be involved in the pathogenesis of primary ciliary dyskinesia and the Kartagener syndrome. 相似文献

Identification of mtDNA mutation in a pedigree with gestational diabetes, deafness, Wolff-Parkinson-White syndrome and placenta accreta 总被引:2,自引:0,他引:2

Mitochondrial DNA (mtDNA) defects are associated with a number of human disorders. Although many occur sporadically, maternal transmission is the hallmark of diseases due to mtDNA point mutations. The same mutation may manifest strikingly different phenotypes; for example, the A to G substitution at np 3243 was first reported in patients with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (the MELAS syndrome), but is also found in patients with diabetes and deafness. Here we present a case of gestational diabetes, deafness, premature greying, placenta accreta and Wolff-Parkinson-White (WPW) syndrome associated with a mtDNA mutation. Although this is the first report of such an association, study of 27 other patients with WPW syndrome failed to confirm that this mtDNA mutation is a common cause of such pre-excitation disorders. 相似文献

Objective of this paper is to review drug-induced movement disorders (D-IMD) treated patients on Department of Neurology in University Hospital Osijek. We reviewed patients treated during 10 years period (from 1992 to 2002). Analysed group consisted of 14 patients. Reasons for hospitalisation were swallowing problems in 6 patients, neuroleptic malignant syndrome (NMS) in 3 patients, stroke in 2 patients, bolus choking in 2 patients, and speech disturbance in 1 patient. Working diagnosis for most of our patients was neurological disease, yet only later D-IMD diagnosis was established excluding primary neurological disease, or as associated disease to basic neurological disorder. Nine patients have diagnosed as Parkinson syndrome, 3 patients as NMS, and 4 as orolingual dyskinesia, either autonomously, or in combination with Parkinson syndrome. D-IMD was most frequently caused by neuroleptics. Thus the small number of patients hospitalised regarding this syndrome on Department of Neurology. 相似文献

Hutchinson-Gilford progeria syndrome (HGPS) is a rare premature aging disorder that belongs to a group of conditions called laminopathies which affect nuclear lamins. Mutations in two genes, LMNA and ZMPSTE24, have been found in patients with HGPS. The p.G608G LMNA mutation is the most commonly reported mutation. The aim of this work was to compile a comprehensive literature review of the clinical features and genetic mutations and mechanisms of this syndrome as a contribution to health care workers. This review shows the necessity of a more detailed clinical identification of Hutchinson-Gilford progeria syndrome and the need for more studies on the pharmacologic and pharmacogenomic approach to this syndrome. 相似文献

This paper presents an analysis of the Arruda accessory pathway localization method for patients suffering from Wolff-Parkinson-White syndrome, with modifications to increase the overall accuracy. The Arruda method was tested on a total of 79 cases, and 91.1% localization performance was reached. After a deeper analysis of each decision point of the Arruda localization method, we considered that the lead aVF was not as relevant as other leads (I, II, III, V1) used. The branch of the decision tree, which evaluates the left ventricle positions, was entirely replaced using different decision criteria based on the same biological parameters. The modified algorithm significantly improves the localization accuracy in the left ventricle, reaching 94.9%. An accurate localization performance of non-invasive methods is relevant because it can enlighten the necessary invasive interventions, and it also reduces the discomfort caused to the patient. 相似文献

The Kaufman-McKusick syndrome (MK 23670) is a rare autosomal recessive disorder characterized by the triad of hydrometrocolpos, postaxial polydactyly, and congenital heart disease. Multiple other anomalies have been ascribed to this syndrome. Hydrometrocolpos, especially if unrecognized, may be a serious, life-threatening condition in the newborn girl. Forty-four cases have been so far reported in the literature. A great phenotypic variability occurs in this syndrome, therefore making it very difficult to identify the disorder at its presentation and classify it correctly. We shall hereafter review current data regarding the prominent clinical features, the diagnosis and treatment of this syndrome. Problems in genetic counseling will be discussed. 相似文献

Hermansky-Pudlak syndrome (HPS) is an autosomal recessive inherited disease consisting of (1) partial oculocutaneous albinism (with nystagmus, strabism, and visual acuity loss), (2) platelet storage pool deficiency (with bleeding diathesis), and (3) disorder of "ceroid" metabolism with a multisystem tissue lysosomal ceroid deposition. HPS is less uncommon in Puerto Rico, where the most important studies have been performed, but is a very rare disease in Europe. HPS basic defect remains unknown, even if an HPS-causing gene was identified in chromosome segment 10q23-q23.3, and several mutations have been reported. The aim of this article is to discuss, on the basis of a review of relevant literature, a new familial HPS clinical variant observed in 2 young sisters (aged 16 and 23 years old, respectively), characterized by the typical symptoms of this syndrome. Our patients also suffered from diffuse interstitial pulmonary disease and an unexpectedly increased platelet aggregation and were prone to bacterial infections. Interestingly, we observed urinary tract abnormality in the younger HPS sister and a porencephalic cyst in the older HPS sister; both of these developmental defects have been reported in the Cross syndrome (or oculocerebral hypopigmentation syndrome). It seems that in our patients, an overlapping of the phenotypic manifestations of different rare syndromes may be present. The presence of ceroid-like autofluorescent material in urinary sediment together with the histologic aspects and the autofluorescence of oral mucosa biopsy are consistent with a ceroid-like lipofuscin storage. HPS should be carefully tested for in suspected cases to prevent the severe visual impairment, rapidly progressive pulmonary fibrosis, and other complications associated with this disorder. 相似文献

A subset of children and adults with Wolff-Parkinson-White (WPW) syndrome develop dilated cardiomyopathy (DCM). Although DCM may occur in symptomatic WPW patients with sustained tachyarrhythmias, emerging evidence suggests that significant left ventricular dysfunction may arise in WPW in the absence of incessant tachyarrhythmias. An invariable electrophysiological feature in this non-tachyarrhythmia type of DCM is the presence of a right-sided septal or paraseptal accessory pathway. It is thought that premature ventricular activation over these accessory pathways induces septal wall motion abnormalities and ventricular dyssynchrony. LV dyssynchrony induces cellular and structural ventricular remodelling, which may have detrimental effects on cardiac performance. This review summarizes recent evidence for development of DCM in asymptomatic patients with WPW, discusses its pathogenesis, clinical presentation, management and treatment. The prognosis of accessory pathway-induced DCM is excellent. LV dysfunction reverses following catheter ablation of the accessory pathway, suggesting an association between DCM and ventricular preexcitation. Accessory pathway-induced DCM should be suspected in all patients presenting with heart failure and overt ventricular preexcitation, in whom no cause for their DCM can be found. 相似文献

The immotile-cilia syndrome: a microtubule-associated defect 总被引:5,自引:0,他引:5
B A Afzelius 《CRC critical reviews in biochemistry》1985,19(1):63-87
The immotile-cilia syndrome is a congenital disorder characterized by all the cilia in the body being either immotile or showing an abnormal and inefficient beating pattern. Most symptoms come from the ciliated airways (nose, paranasal sinuses, and bronchs) and from the middle ear. Two further symptoms are situs inversus and male sterility. Situs inversus occurs in 50% of the cases and this subgroup is termed the Kartagener's syndrome; it might be due to an inability of the embryonic cilia to shift the heart to the left side and situs laterality seems to be a random process in the immotile-cilia syndrome. Male sterility is caused by the spermatozoa being unable to swim progressively; the sperm tail has the same structure as a cilium. In a few cases only the sperm tail or only the cilia of the body are affected. Female patients have a decreased fertility; most are involuntarily childless. The immotile-cilia syndrome is a heterogeneous disorder in that one out of many different genes may be involved. The different subtypes can be distinguished by an electron microscopic examination which will show defects in either one of a number of the ciliary components. 相似文献

In Wolff-Parkinson-White Syndrome (WPW), presence of accessory pathways causes various tachyarrhythmias that lead to different symptoms and clinical conditions in patients. Atrial fibrillation is observed in about 20-30% of this group of patients. Life threatening malignant ventricular arrhythmias and sudden cardiac deaths are observed in patients having rapid conduction in accessory pathways and short antegrade refractory periods (<250 msn). We present a WPW syndrome case that presented to the emergency service with narrow QRS tachycardia and later developed malignant ventricular arrhythmia. 相似文献

By using programmed electrical stimulation of the heart and studying the initiation and termination of reciprocating atrioventricular tachycardia two patients with the Wolff-Parkinson-White syndrome were shown to respond rapidly and consistently to fixed-rate pacing. A demand pacemaker was implanted in each patient, having been modified so as to switch into the fixed-rate mode whenever the tachycardia began, thereby terminating the arrhythmia. This appears to be a promising form of treatment in patients with otherwise intractable paroxysmal tachycardia who have been shown by careful study to respond in this way. 相似文献

Lenz microphthalmia syndrome is an extremely rare inherited disorder, characterized by unilateral or bilateral microphthalmia. In rare cases affected patients exhibit complete absence of eye or blepharoptosis resulting in visual impairment. Additional physical abnormalities are often associated with this disorder, orofacial, digital, skeletal and urogenital abnormalities. Here we present three cases of Lenz microphthalmia with additional manifestations: two brothers of first cousin mating, the elder one has bilateral congenital cataract which is a rare ophthalmological finding in this syndrome and a third case who presented to us because of ambiguous genitalia. She was 12 years old, and reared as a female. Chromosomal analysis showed 46,XY karyotype, and hormonal studies indicated 5-alpha reductase deficiency. This is the first report of the association of 5-alpha reductase deficiency with Lenz microphthalmia syndrome. 相似文献

The analysis of the literature and author's observations of the "EEC" syndrome (ectrodactyly, ectodermal dysplasia and cleft lip/palate) revealed that this is a disorder with an autosomal-dominant type of inheritance with an incomplete penetrance and varying expressivity. Both sexes are affected with the same frequency. The complete form of the syndrome was mentioned in 27 cases only; all other patients had incomplete forms. The combination of two out of 3 main features is enough for the diagnosis of this syndrome. The most common trait of the "EEC" syndrome is ectrodactyly (73/77), clefts of lip or palate were observed in 53 patients out of 77, the ectodermal dysplasia was mentioned in 44 cases. There is an increase of mutation frequency in older parents. 相似文献

Summary Five new cases of ectrodactyly are described. Two patients have the syndrome of ectrodactyly, extodermal dysplasia, and clefting (EEC). In one patient with the EEC syndrome, the disorder seems to represent a new mutation. One woman with isolated ectrodactyly has a daughter with the EEC syndrome. The variation in the clinical expression of this disorder among affected members of the same family makes it difficult to determine whether there may be several mutant alleles responsible for ectrodactyly and its related manifestations. 相似文献

Mutations in the PTPN11 gene are known to cause a large fraction of the cases of Noonan syndrome. The objective of this study was to determine the PTPN11 gene mutation rate in a cohort of clinically well-characterized Brazilian patients with Noonan or Noonan-like syndromes and to study the genotype-phenotype correlation. Fifty probands with Noonan syndrome ascertained according to well-established diagnostic criteria, 3 with LEOPARD syndrome, 5 with Noonan-like/multiple giant cell lesion syndrome, and 3 with neurofibromatosis/ Noonan were enrolled in this study. Mutational analysis was performed using denaturing high-performance liquid chromatography (DHPLC) followed by sequencing of amplicons with an aberrant elution profile. We detected missense mutations in the PTPN11 gene in 21 probands with Noonan syndrome (42%), in all 3 patients with LEOPARD syndrome, and in 1 case with Noonan-like/multiple giant cell lesion syndrome. One patient with neurofibromatosis-Noonan syndrome had a mutation in both the PTPN11 and NF1 genes. The only anomalies that reached statistical significance when comparing probands with and without mutations were the hematological abnormalities. Our data confirms that Noonan syndrome is a genetically heterogeneous disorder, with mutations in the PTPN11 gene responsible for roughly 50% of the cases. A definitive genotype-phenotype correlation has not been established, but the T73I mutation seems to predispose to a myeloproliferative disorder. Regarding Noonan-like syndromes, mutation of the PTPN11 gene is the main causal factor in LEOPARD syndrome, and it also plays a role in neurofibromatosis-Noonan syndrome. Noonan- like/multiple giant cell lesion syndrome, part of the spectrum of Noonan syndrome, is also heterogeneous. 相似文献

Intellectual disability (ID) is a heterogeneous disorder caused by chromosomal abnormalities, monogenic factors and environmental factors. 22q13 deletion syndrome is a genetic disorder characterized by severe ID. Although the frequency of 22q13 deletions in ID is unclear, it is believed to be largely underestimated. To address this issue, we used Affymetrix Human SNP 6.0 array to detect the 22q13 deletions in 234 Chinese unexplained ID patients and 103 controls. After the Quality Control (QC) test of raw data, 22q13 deletions were found in four out of 230 cases (1.7%), while absent in parents of the cases and 101 controls. A review of genome-wide microarray studies in ID was performed and the frequency of 22q13 deletions from the literatures was 0.24%, much lower than our report. The overlapping region shared by all 4 cases encompasses the gene SHANK3. A heterozygous de novo nonsense mutation Y1015X of SHANK3 was identified in one ID patient. Cortical neurons were prepared from embryonic mice and were transfected with a control plasmid, shank3 wild-type (WT) or mutant plasmids. Overexpression of the Y1015 mutant in neurons significantly affected neurite outgrowth compared with shank3 WT. These findings suggest that 22q13 deletions may be a more frequent cause for Chinese ID patients than previously thought, and the SHANK3 gene is involved in the neurite development. 相似文献
