Mutations in the Parkin (PARK2) and the DJ1 (PARK7) gene cause early-onset Parkinson disease (EOPD). We tested 75 Serbian EOPD patients for mutations in both genes by conventional mutational screening (SSCP/dHPLC/sequencing) to detect small sequence alterations and by gene dosage studies (quantitative PCR) to reveal deletions or multiplications of one or more exons. A compound heterozygous Parkin mutation (exon deletion and point mutation; [c.836_972del]+[c.1411C>T]; +1 is first nucleotide of GenBank AB009973.1) was identified in a patient who showed a relatively benign course after a disease onset at 41 years. Another case had a heterozygous exon deletion in DJ1 ([c.253_322del]+[?]) and presented with an age at onset of 45 years and a rapid disease course. In conclusion, Parkin mutations are surprisingly rare in our Serbian EOPD sample, suggesting that the mutation rate depends on the ethnic origin of the patients. Although DJ1 mutations appear to be rare, we confirm their role in EOPD and demonstrate the importance of gene dosage studies. 相似文献

Establishment of a multidisciplinary clinical pharmacology consult service (CPCS) can be an important adjunct to a successful formulary management system. This article describes the model of a CPCS developed at the University of California Davis Medical Center. The CPCS provides patient-specific consultations, serves a leadership role in directing the medical staff toward hospital-wide drug usage guidelines for high cost pharmaceutical agents, and enforces the P & T Committee adopted criteria on selected high-cost or high risk agents. The mission of the CPCS is to provide the P & T Committee with a multidisciplinary mechanism to educate health care providers, improve patient care, establish drug usage criteria, and enforce those criteria. 相似文献

The authors assessed serum copper and lipoprotein concentrations in a group of 67 patients hospitalized successively at the cardiological department. During hospitalization they were subjected to selective coronarography with assessment of the angiographic score. In 35 patients the angiographic examination was made during the chronic stage of IHD (group A), in 32 patients it was indicated on account of acute coronary syndrome (group B). The authors found that serum copper concentrations are significantly higher in patients with acute forms of IHD (group B, p < 0.001). Serum copper concentrations do not correlate significantly with lipoprotein concentrations nor with the extent of coronary atheroclerosis (angiographic score). 相似文献

Genome-wide association studies (GWAS) have identified over 46 SNPs associated with human prostate cancer (PCa). Some studies have shown correlation of the nitric oxide synthase (NOS) NOS3 gene polymorphisms with the risk and/or progression of PCa. This study aimed to evaluate the association of NOS3 gene polymorphisms (−786T>C, −764A>G, −714G>T, −690C>T, −649G>A and 894G>T) with PCa risk and progression. 150 patients with PCa, 150 patients with BPH and 100 age-matched healthy controls were recruited in this study. Genotyping of promoter polymorphisms was performed by bi-directional DNA sequencing, and for 894G>T by RFLP analysis. There was no significant association between the alleles and genotypes of these genetic variants and PCa risk. For −786T>C polymorphism, we found that C allele is associated with absence of metastases, assuming dominant genetic model (P = 0.049; OR, 0.50; 95% CI, 0.25–1.00). It was found that, compared with NOS3 −690C>T variant CC genotype, CT and TT genotypes confer decreased risk of developing metastases (dominant model, P = 0.015, OR, 0.24; 95% CI, 0.07–0.88) and show association with low clinical tumour stage, compared with stages T3 and T4 (dominant model, P = 0.046, OR, 0.20; 95% CI, 0.04–1.02). Genetic variants −764A>G, −714G>T, −649G>A were not detected in our study group. There is evidence of an inverse correlation of the NOS3 894G>T minor allele with high serum PSA (>20 ng/ml) (dominant model, P = 0.013, OR, 0.37; 95% CI, 0.17–0.82). Our results suggest that NOS3 gene polymorphisms are genetic susceptibility factors for the progression of PCa and patient outcome. 相似文献

Myotonic dystrophy (MD) is a multisystem disease affecting numerous organs and systems. Cardiac involvement is frequent. Sudden death, due to fatal cardiac rhythm and conduction disturbances occurs in 30% of patients with MD. The aim of this study was to assess the possibilities and methods of early detection of myocardial and conduction system disturbances. ECG, 24-hr Holter monitoring, echocardiography and electrophysiologic studies of the conduction system (electrophysiologic study) were carried out in 45 patients. Analysis of late ventricular potentials was done in 36 patients. Genetic studies revealed multiplication of CTG triplets in all patients. Cardiological abnormalities were detected in 89% of our patients. Disturbances of intraventricular conduction with prolongation of HV interval were most frequent (72%). Electrophysiologic study was the most sensitive method for detecting heart involvement in MD (positive findings in 87% patients). Abnormal findings were also discovered by Holter monitoring (64%), ECG (58%), analysis of late ventricular potentials (55%) and by echocardiography in 46% patients. The results of this study indicate a high rate of cardiac involvement in MD. 相似文献

OBJECTIVES: Analysis of the CTG-repeat number and three biallelic markers, Alu(+/-), HinfI(+/-), and TaqI(+/-), in the DMPK gene in healthy and myotonic dystrophy type 1 (DM1) Serbian individuals. Also, the consideration of haplotypes in the light of the proposed models of CTG-repeat evolution and origin of the DM1 mutation. MATERIALS AND METHODS: Markers were analyzed by PCR and haplotypes were obtained on 203 unrelated normal chromosomes and 24 unrelated DM1 chromosomes. RESULTS: A strong linkage disequilibrium was detected between the three biallelic markers alone (P <0.0001) and between distinct CTG-repeat size classes and reconstructed haplotypes. Greater than 98% of normal chromosomes contain (+++) and (- - -) haplotypes. The (+++) haplotype is the most common, while the (CTG)(9-17) are the most frequent alleles. We found a complete association of (+++) haplotype with (CTG)(> or =18) and mutated alleles. CONCLUSIONS: (CTG)(9-17)/(+++) haplotype is the ancestral haplotype and DM1 mutation occurred on (CTG)(18-35)/+++ chromosome. 相似文献

Huntington disease (HD) is a well-defined autosomal dominant neurodegenerative disease caused by CAG repeat expansions in HD gene. There are a significant number of HD cases where this mutation was not found and such cases are named HD-like phenotype (HDL). This article reports 48 patients with HDL phenotype. Patients were analyzed on the presence of mutations in prion (PrP), ferritin and junctophilin-3 (JP-3) genes. None of the patients showed the presence of the mutation in analyzed genes. This could suggest that there is some other gene/genes where the mutation can cause the disease with clinical features of HD. 相似文献

The objective of this epidemiological survey was to estimate the frequency and distribution of Myotonic dystrophy type 1 (MD1) (Steinert's disease) in central Serbia, during the period 1983-2002. The data on the number of diagnosed MD1 patients were obtained using the analysis of hospital records, which were examined in all the relevant neurological institutions in central Serbia in the mentioned period. Incidence rate and prevalence were used for the data analysis. In the study period in central Serbia, 154 patients (78 males and 76 females) with MD1 were identified. The average annual incidence rate of MD1 was 1.3 (95% CI-confidence interval 0.1-7.2) per 1,000,000 population, 1.4/1,000,000 (95% CI 0.1-7.2) for males, 1.3/1,000,000 (95% CI 0.1-7.2) for females. The trend of MD1 incidence rates in the observed period in central Serbia had a tendency of the statistically significant decrease, according to the linear model, in both male (y = 0.205 - 0.0066x, p = 0.021) and female populations (y = 0.1788 - 0.0048x, p = 0.032). The prevalence of MD1 on December 31, 2002 in central Serbia was 3.8/100,000 (95% IP 3.2-4.6), 3.7/100,000 (95% IP 3.3 - 4.8) for males, 3.3/100,000 (95% IP 3.0 - 4.4) for females. 相似文献

Sensitivity of culture and polymerase chain reaction for the etiologic diagnosis of erythema migrans
Zore A Ruzić-Sabljić E Maraspin V Cimperman J Lotric-Furlan S Pikelj A Jurca T Logar M Strle F 《Wiener klinische Wochenschrift》2002,114(13-14):606-609
Skin biopsy samples from 150 patients with typical cutaneous manifestation of Lyme borreliosis, erythema migrans, were cultivated for the presence of Borrelia burgdorferi sensu lato in modified Kelly Pettenkofer (MKP) medium and analysed with two different polymerase chain reactions using either flagellin or nested OspA primers. Cultivation was successful in 75 of 150 (50%) skin samples. Out of 70 strains that were typed using PFGE, B. afzelii was identified in 60 (86%), B. garinii in 10 (14%) specimens, while no B. burgdorferi sensu stricto strains were found. B. burgdorferi sensu lato DNA was detected with polymerase chain reaction in 28% and 61% of skin samples, using flagellin and nested OspA primers, respectively. Concordant results in all three procedures employed in the present study were found in 62 (41%) specimens: 25/150 (17%) were positive with all three methods and 37/150 (25%) samples were completely negative. 相似文献
