In this report we describe two siblings, a 17-year-old male and his deceased sister, born to consanguineous parents, and presenting an oculocerebral syndrome with hypopigmentation as first delineated by Cross in 1967. In addition to the cutaneous hypopigmentation, both presented deep mental retardation and spastic tetraplegia with athetoid movements. A remarkable finding in this family is that a third sibling, an otherwise normal 23-year-old male, presents the same hypopigmentation with white-grey hair colour as his two severely affected siblings. 相似文献

X-linked mental retardation with dystonic movements of the hands 总被引:3,自引:0,他引:3

We describe a family with a syndrome of mental retardation, dystonic movements of the hands and dysarthria inherited in an X-linked recessive pattern. DNA marker studies gave a maximum lod score of 2.11 at theta of 0.00 for DXS41 with a likely localization of the gene to Xpter----Xp21. 相似文献

Detection of fungemia obscured by concomitant bacteremia: in vitro and in vivo studies. 总被引:1,自引:5,他引:1 下载免费PDF全文

Our recent clinical experience suggested that bacteremia may interfere with the detection of concomitant fungemia when standard blood culture methods are used. To determine the extent to which bacteria may interfere with fungal isolation from blood cultures, an in vitro model simulating blood cultures taken during concomitant fungemia and bacteremia was created. Each of six bacteria (Staphylococcus epidermidis, Staphylococcus aureus, Streptococcus faecalis, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa) was combined with each of three pathogenic yeasts (Candida albicans, Candida tropicalis, and Torulopsis glabrata) in vented blood culture bottles containing enriched brain heart infusion broth and fresh normal human blood. Blood culture bottles were analyzed at 1, 2, and 7 days of incubation. Gram strains and subcultures onto chocolate and MacConkey agars failed to detect fungi in 37.0, 66.7, and 100% of samples, respectively. However, subcultures onto Sabouraud dextrose agar failed in only 13% of the samples (occurring only with P. aeruginosa). In a rabbit model of concomitant fungemia with C. albicans and bacteremia with P. aeruginosa, no yeasts were recovered from blood cultures despite 100% detection of P. aeruginosa. Therefore, the usual microbiological techniques may be inadequate to detect fungemia when concomitant bacteremia is present. 相似文献

PURPOSE OF REVIEW: Mixed incontinence remains a complex clinical problem for urogynaecologists and generalists alike, as research for new treatments and interventions tend to focus on single-symptom groups. Those with mixed symptoms form a diverse group, which is difficult to study precisely. Recent studies, however, have aimed to classify the subgroups within this heterogeneous group so that the response to treatment can be determined with greater accuracy. This review aims to evaluate these advances and place the research in a clinical context. RECENT FINDINGS: The main developments have occurred with the acknowledgement of the large number of patients with these symptoms, the assessment of patients and attempts to classify symptom predominant types. Responses following pharmacological and surgical treatment have also improved. SUMMARY: There is greater awareness of the prevalence of mixed urinary incontinence, which has a large impact on the quality of life of women, irrespective of their desire to seek medical help. Tools are available to identify different subgroups within the sphere of mixed urinary incontinence, and, once accurately assessed, patients can expect good outcomes from treatment. Further collaboration between units will lead to more consistent information being published. 相似文献

Von Hippel-Lindau disease (VHL) is an autosomal dominantly inherited disorder, characterised by the development of clear cell renal carcinomas, CNS hemangioblastomas, retinal angiomas, pancreatic tumors, pheochromocytomas and hepatic cysts. Recently a number of families with dominant familial pheochromocytoma as the only clinical manifestation have been reported to carry mutations in the VHL gene. We describe a family in which a novel VHL S68W mutation was segregating and carrier individuals manifested with variable penetrance of isolated pheochromocytomas. Investigation of this kindred confirmed that a mutation in the VHL gene could produce isolated pheochromocytomas as the only clinical feature and was variably penetrant.

In patients with Alzheimer's disease, amyloid fibrils that are aggregates of A4 protein subunits are deposited in the brain. A similar process occurs at an earlier age in persons with Down's syndrome. To investigate the deposition of amyloid in these diseases, we used a radioimmunoassay to measure levels of the amyloid precursor (PreA4) in the serum of 17 patients with Down's syndrome, 15 patients with Alzheimer's disease, and 33 normal elderly controls. The mean (+/- SD) concentration of serum PreA4 was increased 1.5-fold in patients with Down's syndrome (2.49 +/- 1.13 nmol per liter) as compared with that in controls (1.68 +/- 0.49 nmol per liter; P less than 0.007); the levels in patients with Alzheimer's disease were similar to those in controls (1.83 +/- 0.78; P less than 0.98). We also found that the concentration of PreA4 in the brain tissue of two adults with Down's syndrome (100 and 190 pmol per gram) was higher than that in the brain tissue of either 26 patients with Alzheimer's disease (64.4 +/- 17.3 pmol per gram) or 17 elderly controls with neurologic disease (68.5 +/- 26.3 pmol per gram). Immunocytochemical studies of brain tissue from 26 patients with Down's syndrome showed that the deposition of A4 protein amyloid began in these patients approximately 50 years earlier than it began in 127 normal aging subjects studied previously, although the rate of deposition was the same. We conclude that, since the gene for PreA4 is on the long arm of chromosome 21, which is present in triplicate in Down's syndrome, overexpression of this gene may lead to increased levels of PreA4 and amyloid deposition in Down's syndrome. However, since increased levels of PreA4 are not present in Alzheimer's disease, additional factors must account for the amyloid deposition in that disorder. 相似文献
