Optical quality in eyes with aspheric intraocular lenses and in younger and older adult phakic eyes: comparative study.
2009
To compare ocular higher-order aberrations (HOAs) in eyes with aspheric intraocular lenses (IOL) and in phakic eyes.Department of Ophthalmology, Military Health Service Institute, Warsaw, Poland.Higher-order aberrations with a 5.0 mm pupil and best spectacle-corrected visual acuity (BSCVA) were analyzed in a young phakic group (age 20 to 40 years), older phakic group (age 40 to 60 years), and a pseudophakic group (age 62 to 84 years; SN60WF aspheric IOL).The mean coma was 0.13 microm+/-0.07 (SD) in the younger phakic group, 0.18+/-0.08 microm in the older phakic group, and 0.16+/-0.08 microm in the pseudophakic group; the difference between the 2 phakic groups was statistically significant …
Implant treatment in atrophic posterior mandibles: Vertical regeneration with block bone grafts versus implants with 5.5-mm intrabony length
2014
Purpose: To retrospectively compare the outcomes of implants placed in posterior mandibles vertically regenerated with onlay autogenous block bone grafts and short dental implants. Materials and Methods: Consecutive patients with vertical bone atrophy in edentulous mandibular posterior regions (7 to 8 mm of bone above the inferior alveolar nerve) were treated with either implants placed in regenerated bone using autologous block bone grafts (group 1) or short implants (with 5.5-mm intrabony length) in native bone (group 2) between 2005 and 2010 and followed for 12 months after loading. The procedure used was the established treatment protocol for this type of patient at the Oral Surgery Uni…
Prospective randomized comparison of short-access mother-baby cholangioscopy versus direct cholangioscopy with ultraslim gastroscopes
2012
Mother-baby technologies, the criterion standard for cholangioscopy, have several limitations. A novel, short-access, mother-baby (SAMBA) system may improve this technique. Direct cholangioscopy (DC) was recently developed as an alternative to mother-baby cholangioscopy.Comparison of success rates with SAMBA and DC.Single-center, randomized, controlled trial.Academic tertiary-care referral center.Sixty patients with suspected cholangiopathies randomized to either SAMBA (n = 30) or DC (n = 30).Cholangioscopy under deep sedation.Technical success rate of diagnostic or therapeutic procedure.A total of 24 and 21 diagnostic procedures were performed in the SAMBA and DC groups, respectively.

Sutureless ciliary sulcus supported intraocular lens with transiridal anchoring haptics.
2003
We report a technique for implanting intraocular lenses (IOLs) in the ciliary sulcus in eyes without capsule support. The IOL design allows it to be implanted without fixation sutures. The lens was implanted in 3 aphakic eyes without capsule support.
Case study: effect of handrim diameter on performance in a paralympic wheelchair athlete.
2009
This study, with a top T-52 class athlete, determines the relationship between stroke frequency (SF) and push time (PT) and wheelchair velocity (Wv) using different handrim diameters (HD) and the effect of different HDs on the athlete’s heart rate (HR) and blood lactate (LACT) at competition speeds. Wv shows a linear-direct relationship with SF but a linear-inverse relationship with PT (p < .001 in both cases). Using bigger handrims (0.37 m instead of 0.36 m), SF increases 6%, while PT decreases 27% (at 24 Km·h–1). HR (p < .0001) increases with Wv and is also affected by HD with differences between the 0.34 m—0.36 m handrim group (lower values) and the 0.37 m handrim (higher values). …
Subfascial Endoscopic Perforator Surgery With Tumescent Local Anesthesia
2002
background. Subfascial endoscopic perforator surgery (SEPS) has become an established procedure. objective. To evaluate SEPS with tumescent local anesthesia (TLA) using an single-port device originally designed for that purpose. methods. Patients selected for SEPS received subcutaneous infiltration of TLA into the medial aspect of the calf 20 minutes before surgery. Bipolar coagulation and dissection were used to treat incompetent perforators. results. Fifty-one patients with 67 legs of CEAP stages C3–C6 underwent SEPS with TLA. In 40 patients or 53 legs (79.1%) TLA alone allowed successful completion of the SEPS procedure. Five patients with 7 legs (10.4%) required additional intravenous a…
Effect of custom-made and prefabricated insoles on plantar loading parameters during running with and without fatigue.
2014
Controversy exists whether custom-made insoles are more effective in reducing plantar loading compared to prefabricated insoles. Forty recreational athletes ran using custom-made, prefabricated, and the original insoles of their running shoes, at rest and after a fatigue run. Contact time, stride rate, and plantar loading parameters were measured. Neither the insole conditions nor the fatigue state modified contact time and stride rate. Addressing prevention of running injuries, post-fatigue loading values are of great interest. Custom-made insoles reduced the post-fatigue loading under the hallux (92 vs. 130 kPa, P0.05), medial midfoot (70 vs. 105 kPa, P0.01), and lateral midfoot (62 vs 96…
Prevalence of complications after the oral rehabilitation with implant-supported hybrid prostheses
2010
Objectives: Assess the main problems referred by the patients and observed by the professionals after the bucodental rehabilitation with an implant-supported hybrid prothesis. Patient and Methods: A retrospective study was carried out in which there were 43 patients included who were visited in the Department of Oral Surgery and Orofacial Implantology of University of Barcelona Dental School for one year. An oral rehabilitation with an implant-supported hybrid prosthesis was made to those patients. The following variables were registered: age, gender, number of inserted implants, type of implant and principal problems produced by the hybrid prosthesis. Results: The rehabilitation with an im…
Survival and tissue maintenance of an implant with a sloped configurated shoulder in the posterior mandible-a prospective multicenter study.
2016
Aim Clinical studies evaluating the influence of the implant design on the preservation of peri-implant keratinized mucosa are rare. The aim of this prospective multicenter study was to investigate the survival, and soft and hard tissue maintenance of an implant with a sloped shoulder configuration, when placed in the posterior mandible. Material and Methods In this study, 24 centers participated and 184 patients receiving 238 implants (OsseoSpeed™ Profile TX implants) were included. Clinical assessments of soft tissue parameters were performed before implant placement, immediately after implant placement, at prosthetic delivery and at 6, 12 and 24 months after implant placement and margina…
What are depressive symptoms in acutely ill patients with schizophrenia spectrum disorder?
2014
AbstractBackground:Aim was to examine depressive symptoms in acutely ill schizophrenia patients on a single symptom basis and to evaluate their relationship with positive, negative and general psychopathological symptoms.Methods:Two hundred and seventy-eight patients suffering from a schizophrenia spectrum disorder were analysed within a naturalistic study by the German Research Network on Schizophrenia. Using the Calgary Depression Scale for Schizophrenia (CDSS) depressive symptoms were examined and the Positive and Negative Syndrome Scale (PANSS) was applied to assess positive, negative and general symptoms. Correlation and factor analyses were calculated to detect the underlying structur…
