PURPOSE To assess the usefulness of flexible covered metallic stents in the palliation of malignant obstruction of the gastric outlet and duodenum. MATERIALS AND METHODS Twenty-four consecutive patients with malignant obstruction of the gastric outlet (n = 22) or duodenum (n = 2) underwent palliative treatment with self-expandable flexible covered(More)
DNA samples from 26 cervical carcinoma and normal tissue pairs were studied by restriction fragment length polymorphism (RFLP) analysis to determine the frequency of loss of heterozygosity (LOH) on 17p. Allelic loss in the p13.1 region of chromosome 17, known to contain the TP53 locus, was not detected in any of 10 informative cases. Instead, LOH was(More)
Purpose. To evaluate the soft tissue stability around single implants inserted to replace maxillary lateral incisors, using an innovative 3D method. Methods. We have used reverse-engineering software for the superimposition of 3D surface models of the dentogingival structures, obtained from intraoral scans of the same patients taken at the delivery of the(More)
With increasing demand for ultra-high-energy-density storage systems, considerable effort has been recently focused on Li − O 2 batteries. [ 1–4 ] The Li − O 2 battery can deliver substantially higher energy density ( ∼ 3500 Wh kg − 1 ) than conventional Li − ion batteries. [ 4 , 5 ] However, such key limitations, including poor cyclability, low Coulombic(More)
We describe our experience with the 'four-in-one' procedure for habitual dislocation of the patella in five children (six knees). All the patients presented with severe generalised ligamentous laxity and aplasia of the trochlear groove. All had a lateral release, proximal 'tube' realignment of the patella, semitendinosus tenodesis and transfer of the(More)
BACKGROUND We evaluated the differences in sample adequacy and safety between a transseptal needle and Quick-core biopsy needle for transjugular liver biopsy. METHODS Eighteen consecutive patients who had a bleeding diatheses and/or ascites underwent transjugular liver biopsy using a transseptal needle (11 patients) and Quick-core biopsy needle (seven(More)
Bowen's disease can be treated by various methods, including surgical excision, cryosurgery, laser ablation, curettage, Mohs' microsurgery and ionizing radiation. Radiotherapy has been a useful therapeutic modality in the treatment of Bowen's disease and other skin cancers in areas which are difficult to excise, especially the central areas of the face,(More)
BACKGROUND Stage IIb bulky cervical carcinomas have been considered difficult to treat successfully by radiation and/or surgery, compared with smaller lesions. This study was designed to evaluate the efficacy of neoadjuvant pelvic intraarterial chemotherapy (IAC) and to determine the optimal dosage of cisplatin for reducing tumor volume in these patients.(More)
The authors assessed the efficacy of an antireflux valve stent in the palliation of malignant esophagogastric junction (EGJ) obstruction after in vitro testing of the stent. Seventeen patients with inoperable malignant EGJ obstruction were treated. Antireflux valves, made of three polyurethane leaflets, were attached to the distal part of the stent to(More)
This study was performed to determine whether there is a linear correlation between serum squamous cell carcinoma (SCC) antigen levels and tumor volumes in patients with cervical carcinoma. Sera from 43 patients with stage IIb bulky (>4 cm) cervical carcinoma were collected prospectively and assayed for SCC antigen levels before, and 2 weeks after, three(More)
