PC466: Long-term results after placing dental implants in patients with Papillon-Lefèvre syndrome - incalculable risk or real treatment option?

Introduction. In esotropia with larger angles > near than at distance, splitting of the medial rectus muscle has been suggested as a treatment option. Previous reports of bilateral medial rectus Y-splitting as a first intervention showed a reduction of the distance/near disparity with fewer side effects compared to posterior fixation surgery. We address whether a medial rectus Y-splitting as a secondary and/or a unilateral procedure also reduce distance/near disparity.Materials and Methods. We retrospectively reviewed the charts of four patients undergoing Y-split recession as a second and/or unilateral surgery. Main outcomes were distance/near disparity and squint angles.Results and Discussion.Three of the four patients had undergone unilateral Y-splitting of the medial rectus as a secondary surgery, three as a unilateral procedure. Mean distance/near disparity was reduced from 17 PD preoperatively to zero at the final follow-up (FU). Preoperative angles ranged from 45 PD to 66 PD at near and from 25 PD to 55 PD at distance. At the final FU, these angles ranged from 0 PD to 20 PD at near and at distance. Mean FU was 42 months (range: 12–60 months).Conclusion. Y-split recession as a secondary and/or unilateral surgery for distance/near esotropia can reduce distance/near disparity with good long-term results. Residual esotropia can be corrected by adding resection of the lateral rectus muscle.

Purpose: To evaluate the long-term results of remote iliac artery endarterectomy (RIAE) in 2 vascular referral centers and review existing literature. Methods: A retrospective analysis was conducted of 109 consecutive patients (mean age 64.2±10.7 years; 72 men) who underwent 113 RIAE procedures for lower limb ischemia from January 2004 to August 2015 at 2 vascular centers. The majority of limbs (82, 72.6%) had TASC II D lesions (31 TASC II C). Primary outcome measures were primary, assisted primary, and secondary patency. A comprehensive literature search was performed in the PubMed and EMBASE databases to identify all English-language studies published after 1990 reporting the results of RIAE. Results: Technical success was achieved in 95 (84.1%) of the 113 procedures. The complication rate was 13.7%, and 30-day mortality was 0%. At 5 years, primary patency was 78.2%, assisted primary patency was 83.4%, and secondary patency was 86.7%. Hemodynamic success was obtained in 91.7% of patients, and clinical improvement was observed in 95.2%. Freedom from major amputation was 94.7% at 5 years. The systematic review comprised 6 studies including 419 RIAEs, and pooled data showed results similar to the current study. Conclusion: For external iliac artery occlusions extending into the common femoral artery, RIAE appears to be a valuable hybrid treatment option. It combines acceptable morbidity and low mortality with good long-term patency. It has some advantages over an open surgical iliofemoral bypass or complete endovascular revascularization and could be the best treatment option in selected cases.

Alternative Treatment Option

OBJECTIVEGlomus jugulare tumors are rare indolent tumors that frequently involve the lower cranial nerves (CNs). Complete resection can be difficult and associated with lower CN injury. Gamma Knife radiosurgery (GKRS) has established its role as a noninvasive alternative treatment option for these often formidable lesions. The authors aimed to review their experience at the National Centre for Stereotactic Radiosurgery, Sheffield, United Kingdom, specifically the long-term tumor control rate and complications of GKRS for these lesions.METHODSClinical and radiological data were retrospectively reviewed for patients treated between March 1994 and December 2010. Data were available for 75 patients harboring 76 tumors. The tumors in 3 patients were treated in 2 stages. Familial and/or hereditary history was noted in 12 patients, 2 of whom had catecholamine-secreting and/or active tumors. Gamma Knife radiosurgery was the primary treatment modality in 47 patients (63%). The median age at the time of treatment was 55 years. The median tumor volume was 7 cm3, and the median radiosurgical dose to the tumor margin was 18 Gy (range 12–25 Gy). The median duration of radiological follow-up was 51.5 months (range 12–230 months), and the median clinical follow-up was 38.5 months (range 6–223 months).RESULTSThe overall tumor control rate was 93.4% with low CN morbidity. Improvement of preexisting deficits was noted in 15 patients (20%). A stationary clinical course and no progression of symptoms were noted in 48 patients (64%). Twelve patients (16%) had new symptoms or progression of their preexisting symptoms. The Kaplan-Meier actuarial tumor control rate was 92.2% at 5 years and 86.3% at 10 years.CONCLUSIONSGamma Knife radiosurgery offers a risk-versus-benefit treatment option with very low CN morbidity and stable long-term results.

Different Response

Prosthetic rehabilitation of total edentulous jaws patients is today a common technique that clinicians approach in their daily practice. The use of dental implants for replacing missing teeth is going to be a safe technique and the implant-prosthetic materials give the possibility of having long-term clinical success. Aim of this work is to evaluate the mechanical features of three different prosthetic retention systems. By applying engineering systems of investigations like FEM and von Mises analyses, how the dental implant material holds out against the masticatory strength during the chewing cycles has been investigated. Three common dental implant overdenture retention systems have been investigated. The ball attachment system, the locator system, and the common dental abutment have been processed by Ansys Workbench 15.0 and underwent FEM and von Mises investigations. The elastic features of the materials used in the study have been taken from recent literature data. Results revealed different response for both types of device, although locator system showed better results for all conditions of loading. The data of this virtual model show all the features of different prosthetic retention systems under the masticatory load. Clinicians should find the better prosthetic solution related to the patients clinical condition in order to obtain long-term results.

The long-term clinical and radiological outcomes of dental implants inserted in augmented bone treated with platelet-rich plasma (PRP) has not been well addressed in the literature yet. This study is based on a collection of patients from a randomized controlled trial (RCT) that did not report any short-term positive effects of PRP on bone healing after sinus lift surgery using autologous iliac crest bone graft. This study aimed to evaluate the long-term impact of PRP regarding clinical and radiological outcomes on the inserted implants in the previous RCT. For this evaluation, we considered the following variables: plaque index, probing depth, bleeding index, mobility grade, Periotest® values, and radiological bone loss. Out of 53 patients (n = 306 implants) included in the previous study we were able to reinvestigate 37 patients (n = 210 implants) in two centers (31 in Giessen, Germany and 6 in Erlangen, Germany). Clinical and radiographic parameters suggested overall healthy conditions of the peri-implant tissue. The PRP-group and the control group did not differ significantly in the majority of the parameters. The overall evaluation showed that result data of the PRP-group was inferior to the control group in 64 percent of the evaluated parameters. The present study cannot provide evidence of a positive effect of PRP on the long-term implant clinical and radiological outcomes. In fact, a tendency towards inferior long-term results in the PRP-group was detected without reaching a significant threshold. Further controlled trials need to be conducted to investigate this correlation.

The Mean

Background Hip arthrodesis was once considered as a preferred treatment option in young people with hip arthritis. The purpose of this retrospective study was to evaluate the long term outcome following conversion of hip arthrodesis to arthroplasty The main indications for conversion were back pain and ipsilateral muscular or knee pain. Methods Sixty-eight procedures in 67 patients performed between 1963 and 2000 at Wrightington Hospital were evaluated. Results The mean age at the time of hip arthrodesis was 16.7 years (3 to 39 years). The mean age at the time of conversion was 48.7 years (24 to 74 years). The Merle d'Aubigné score improved from a mean of 8.81 pre-operatively to 13.6 at the latest follow-up. Complications included DVT (3 patients), transient foot drop (1 patient), and hepatitis following blood transfusion (1 patient). Seven patients required further revision surgery following conversion. Conclusions Arthrodesis remains a sensible and safe treatment option maintaining independent mobility without multiple operations or significant bone loss for 20–30 years which subsequently can be successfully converted to an arthroplasty.
