Stent implantation using a Cheatham Platinum (CP) stent for coarctation of the aorta (CoA) is a promising treatment alternative to traditional surgical repair. However, there are no earlier reports in the literature focusing on use of this stent in a Taiwanese patient. Herein we report a 16-year-old boy with CoA presenting with heart murmur and exercise intolerance who underwent successful CP stent placement. However, severe hypertension with arterial blood pressure increasing to 207/104 mmHg occurred four hours after stent implantation...

The objective of the present study was to elucidate stability development of immediately loaded hybrid self-tapping implants inserted in the posterior maxilla. Forty-eight hybrid self-tapping implants with a chemically modified surface (∅4.1; length 8 mm) were inserted bilateral in the maxillary 1st and 2nd premolar and 1st molar sites of eight patients. In each patient, both sides of maxilla were randomly assigned to either immediate (IL) or early (EL) loading group. Implant stability was evaluated by means of resonance frequency analysis immediately after implant placement and after 1, 2, 3, 4, 5, 6, 12, 26 and 52 weeks...

An association between vitamin D deficiency and early dental implant failure is not properly verified, but its role in osteoimmunology is discussed. This article illustrates two case reports with vitamin D deficiency and early implant failure. Prior to implant placement, the first patient received crestal bone grafting with autologous material. Both patients received dental implants from different manufacturers in the molar region of the mandible. In the case of bone grafting in the first patient, all implants were placed in a two-stage procedure...

Subclavian vein puncture is a relatively fast and safe technique to access the right heart for placement of pacemaker leads. Hemothorax related to injury of the pulmonary artery (PA) is a rare complication of subclavian vein access but can be life-threatening. We report a case of hemothorax occurring after subclavian vein puncture for pacemaker implantation. No cases of transcatheter arterial embolization for PA injury secondary to pacemaker implantation have been reported. Understanding of this rare complication after pacemaker implantation along with its specific clinical presentation may lead to early diagnosis and intervention...

Revision total knee arthroplasty (TKA) can be challenging in the setting of bone loss. Previously, severe bone loss was managed with impaction grafting and structural allografts; however, these had limited success. Recently, metaphyseal cones have been developed as useful adjuncts with good early outcomes. Presently, there are no published guidelines on how to preoperatively predict the need for metaphyseal cone implantation radiographically. Therefore, the purpose of this study was to evaluate how well preoperative radiographs were able to predict the use of cones in a small series of patients undergoing revision TKA...

BACKGROUND: Previous studies have shown that adequate thickness or initial augmentation of soft tissue has a positive effect on the stability of peri-implant bone. This randomized, controlled trial aimed to evaluate the influence of augmenting soft tissue with platelet-rich fibrin (PRF) on crestal bone and soft tissue around implants. METHODS: After randomization, 31 fully threaded titanium implants were inserted in 31 patients (16 men and 15 women) in the lower mandible using a split-flap technique...

Exhaustion of superficial veins coupled with the presence of intrathoracic central venous occlusions remains a significant obstacle for hemodialysis access creation; complex arteriovenous graft (AVG) configurations have been described. The axillary-iliac AVG was first reported in 1987, and few authors have explored this access. We evaluated our experience with this AVG configuration utilizing the early cannulation (EC) graft Flixene™ (Atrium ™, Hudson, NH, USA). Eight patients (75 % men; mean age 37 ± 10 years) with End-Stage Renal Disease (ESRD) underwent axillo-iliac AVG creation with Flixene™ grafts; all had exhausted peripheral veins, occluded thoracic central veins, and inadequate femoral veins...
