Bone-to-implant contact of orthodontic implants in humans--a histomorphometric investigation
2008
The purpose of the present study was to evaluate the percentage of direct bone-to-implant contact (BIC) of orthodontic anchorage implants (Orthosystem) after active orthodontic treatment. Twenty orthodontic implants (diameter, 3.3 mm; length, 4 or 6 mm) were inserted for orthodontic anchorage in different anatomical regions of 18 adult patients (nine males, nine females) aged 18-63 years. Fifteen implants (one per patient) were placed in the mid-palatal area, one implant (one patient) in the retromolar area of the mandible, one in the retromolar area and the mid-palatal area (one patient), and two (bilaterally, one patient) in the zygomatic area. The duration of the unloaded healing period …
Prevalence of cataract after collagen copolymer phakic intraocular lens implantation for myopia, hyperopia, and astigmatism
2015
Purpose To evaluate the prevalence of cataract after Implantable Collamer Lens phakic intraocular lens (pIOL) implantation with different models at different ages and for different refractive powers. Setting Fernandez-Vega Ophthalmological Institute, Oviedo, Spain. Design Retrospective nonrandomized clinical study. Methods The pIOL (models V4, V4b, or V4c) was implanted in all cases. Results The study included 3420 eyes (1898 patients). The mean patient age at surgery was 31.2 years ± 6.4 (SD) (range 18 to 50 years) and the mean spherical refractive error, −7.27 ± 5.24 diopters (D) (range −26.5 to 12.5 D). Twenty-one eyes (0.61%) of 15 patients had pIOL explantation (all model V4) because c…
Rate of Cataract Formation in 343 Highly Myopic Eyes After Implantation of Three Types of Phakic Intraocular Lenses
2004
ABSTRACT PURPOSE: To assess the feasibility of using phakic intraocular lenses (PIOL) to treat high myopia, and evaluate the incidence of cataract, comparing three different lens types. METHODS: From 1989 to 2002, we implanted three different phakic intraocular lenses (PIOL) in 343 eyes of 232 patients; 231 eyes recieved an Ophtec (Worst-Fechner model, iris-claw), 89 an Adatomed (silicone posterior chamber), and 23 a Staar (posterior chamber, models V2, V3, V4). Average follow-up was 96.2 months for the Ophtec group, 31.5 months for the Adatomed group, and 19.3 months for Staar group. Eyes that subsequently developed cataract were studied for clinical evolution and had PIOL explantation and…
Complex radial head and neck fractures treated with modern locking plate fixation
2019
Background Internal fixation of complex radial head and neck (CRHN) fractures is difficult, and postoperative complications are common. This study evaluated elbow function and patient clinical status after internal fixation of CRHN fractures with modern locking plates. Methods We included 40 patients with 41 fractures (1 bilateral lesion). In 25 patients (61%), a concomitant injury was found. Patients were an average age of 46 years (range, 22-70 years). The mean follow-up time was 36 months (range, 2-70 months). Postoperative assessments included evaluation of range of motion, functional scores, and radiologic findings. We assessed fracture healing, surgical complications, revision surgery…
Functional results after operative treatment of olecranon fractures.
2004
In a retrospective, nonrandomized study, we reviewed our experience with the operative treatment of olecranon fractures to find out which factors correlate with subjective complaints and functional outcome. A total of 95 consecutive olecranon fractures were operatively treated in our level I trauma institution between March 1, 1992 and March 1, 2000. Medical charts and radiographs of all patients were evaluated. Three patients died, 23 were lost to follow-up. Fifty-eight of 69 available patients (84.0%) were reviewed clinically and/or radiologically after a mean time interval of 36 months. Fracture type, fracture classification, associated lesions, technical correctness of osteosynthesis, a…
Partial versus complete removal of the infected mesh after abdominal wall hernia repair.
2017
Background: To compare the results with complete mesh removal (CMR) versus partial mesh removal (PMR) in the treatment of mesh infection after abdominal wall hernia repair (AWHR). Methods: Retrospective review of all patients who underwent surgery for mesh infection between January 2004 and May 2014 at a tertiary center. Results: Of 3470 cases of AWHR, we reported 66 cases (1.9%) of mesh infection, and 48 repairs (72.7%) required mesh explantation. CMR was achieved on 38 occasions, while PMR was undertaken ten times. We observed more postoperative complications in CMR than PMR group (p = 0.04). Three patients with intestinal fistula were reoperated in postoperative period after a difficult …
Predictors of mesh infection and explantation after abdominal wall hernia repair
2015
Abstract Background The main objective was to identify predictive factors associated with prosthesis infection and mesh explantation after abdominal wall hernia repair (AWHR). Methods This is a retrospective review of all patients who underwent AWHR from January 2004 to May 2014 at a tertiary center. Multivariate analysis identified predictors of mesh infection and explantation after AWHR. Results From 3,470 cases of AWHR, we reported 66 cases (1.9%) of mesh infection, and 48 repairs (72.7%) required mesh explantation. Steroid or immunosuppressive drugs use (odds ratio [OR] 2.22; confidence interval [CI] 1.16 to 3.95), urgent repair (OR 5.06; CI 2.21 to 8.60), and postoperative surgical sit…
Long-term results of the use of silicone sheets after diskectomy in the temporomandibular joint: clinical, radiographic and histopathologic findings
1999
The aim of the present study was to evaluate the long-term results of a group of patients who had the disk of the temporomandibular joint (TMJ) removed and permanently replaced by a silicone sheet. The study group comprised 48 patients, treated in the period from 1983 to 1993. In eight patients, the implants had to be removed after an average interval of 5.6 years and they were submitted for histopathological examination. Twenty-five of the 40 patients with silastic implants in place, and five of the 8 patients who had their implants removed, were available for long-term follow-up (mean interval of 7.0 years, SD 2.8 years). Clinical function was rated according to the Helkimo Dysfunction In…
Complications of Poly Implant Prothèse breast implants: the current discussion
2013
Against the background of the current discussion about Poly Implant Prothèse (PIP, Seyne-sur-mer, France) breast implants, we want to present a case demonstrating the complications such as implant rupture, silicone dissemination and level III silicone lymphadenopathy. A 29-year-old woman with cosmetic breast augmentation with PIP implants 5 years previously showed a sensitive swelling in her right axilla and neck region. All tests to detect an infectious or lymphomatous lymphadenopathy were negative. After ultrasound and MRI, rupture of the right implant was assumed and multiple pathologically enlarged lymph nodes up to supraclavicular region were shown. An excision biopsy of one axillary l…
Effect of cost on early removal of contraceptive implants: a prospective cohort study
2019
OBJECTIVES To evaluate the effect of the cost of subdermal etonogestrel implant (SEI) on the continuation rate one year after insertion, and to assess the reasons given by users to remove the implant before the expiration date. METHODS Prospective cohort study conducted among 265 women who chose the SEI as a contraceptive method in a sexual and reproductive health center in the eastern region of Spain, between October/2012 and October/2017. The sample was divided into two cohorts depending on the cost of the implant for the user (free-of-charge or requiring partial payment). Kaplan-Meier survival curves were used to compare the cumulative removal rates of free implants with partially paid i…
