Correction
The authors wish to add the following correction to this paper:
The genomic organization of the human organic cation transporter (hOCT1/SLC22A1) has recently been described by us to consist of 7 exons [Molecular cloning, functional characterization and genomic organization of four alternatively spliced isoforms of the human organic cation transporter 1( hOCT1 / SLC22A1 ); Ann. Hum. Genet . 63 : 473–482]. A reexamination revealed 11 exons instead of 7. The mistake occurred through cDNA contamination. The corrected gene structure of the hOCT1 gene is available at EMBL under the following accession numbers:
AJ243995 (Exon 1), AJ243996 (Exon 2), AJ276051 (Exon 3), AJ276052 (Exon 4), AJ276053 (Exon 5 and 6), AJ245460 (Exon 7), AJ243998 (Exon 8), AJ243999 (Exon 9 and 10) and AJ244000 (Exon 11).     

Volumetric rendering techniques: applications for three-dimensional imaging of the hip

Volumetric rendering is a new approach to three-dimensional (3D) imaging that overcomes many of the drawbacks of currently available surface-rendering systems. Its application on the Pixar Imaging System in two cases of acetabular fracture was assessed to illustrate the features of the technique. The fast-computing architecture and large memory of this system allow rapid generation of a series of high-quality 3D images in each plane of rotation (x or spinal axis, z or somersaulting axis) that can be viewed as independent static images or as an animated real-time video loop. Editing to remove the normal contralateral hemipelvis enhances appreciation of acetabular abnormalities. Every pixel of computed tomographic data is preserved, allowing representation of both soft tissue and bone as translucent overlap. The presentation of data also allows detection of subtle abnormalities and features and minimizes the artifact generation common in surface-rendered images.

Indium-111 labeled platelet deposition following transfemoral angiography

The incidence of thromboembolitic events in patients undergoing transfemoral angiography was examined using indium-111 labeled platelets. Twenty-seven patients received approximately 300 muCi of autologous labeled platelets at least 3 hours before angiography and were scanned with a gamma camera immediately before and after angiography. All patients were free of clinically obvious complications in the 1-2 day period after angiography. Our results showed evidence of platelet deposition at 21 sites other than the puncture site in 12 (44%) patients. Most platelet deposition (54%) occurred along the region between the puncture site and the aortic bifurcation; 24% occurred at sites not traversed by the catheter. At the puncture site itself, there was substantial platelet uptake in 44% of patients. This study indicates the need for further work in determining the most suitable catheter material and in assessing the efficacy of other measures such as anticoagulant or antiplatelet therapy.     

Incidence and mortality of venous thrombosis: a population-based study

Background: Estimates of the incidence of venous thrombosis (VT) vary, and data on mortality are limited. Objectives: We estimated the incidence and mortality of a first VT event in a general population. Methods: From the residents of Nord‐Trøndelag county in Norway aged 20 years and older (n = 94 194), we identified all cases with an objectively verified diagnosis of VT that occurred between 1995 and 2001. Patients and diagnosis characteristics were retrieved from medical records. Results: Seven hundred and forty patients were identified with a first diagnosis of VT during 516 405 person‐years of follow‐up. The incidence rate for all first VT events was 1.43 per 1000 person‐years [95% confidence interval (CI): 1.33–1.54], that for deep‐vein thrombosis (DVT) was 0.93 per 1000 person‐years (95% CI: 0.85–1.02), and that for pulmonary embolism (PE) was 0.50 per 1000 person‐years (95% CI: 0.44–0.56). The incidence rates increased exponentially with age, and were slightly higher in women than in men. The 30‐day case‐fatality rate was higher in patients with PE than in those with DVT [9.7% vs. 4.6%, risk ratio 2.1 (95% CI: 1.2–3.7)]; it was also higher in patients with cancer than in patients without cancer [19.1% vs. 3.6%, risk ratio 3.8 (95% CI 1.6–9.2)]. The risk of dying was highest in the first months subsequent to the VT, after which it gradually approached the mortality rate in the general population. Conclusions: This study provides estimates of incidence and mortality of a first VT event in the general population.     

Total cavopulmonary anastomosis using atrial septal flap: technique and early results

Introduction The Fontan procedure has undergone many modifications to avoid atrial arrhythmias and thrombus formation. We used patient’s interatrial septum as a flap to direct the inferior venacaval blood to the superior venacava. Methods Seventeen patients, aged 1 to 17 years, underwent modified total cavopulmonary anastomosis. Interatrial septum was used to create the inner half of the atrial tunnel, outer half being formed by right atrial free wall. Post-operatively, all patients underwent echocardiography. Seven patients underwent 24 hour ambulatory Holter monitoring and 6 patients underwent cardiac catheterization and cineangiography. Results There was one early death due to low cardiac output. One patient had transient supraventricular arrhythmia. Two patients had singnificant pleural effusion. Holter Monitoring reveled sinus rhythm in all 7 patients studied. Follow up ranged from 18 to 60 months and patients were evaluated as they came for follow up. Long term follow up is currently being compiled. There was one late death from a non-cardiac cause. The remaining patients were in New York Heart Association (NYHA) Class I or II. All patients were in sinus rhythm. Echocardiography and cineangiography revealed absence of obstruction or leak. Conclusions Total cavopulmonary anastomosis using autogenous atrial septum is a useful modification for classical cavopulmonary anastomosis and provides good early results.
