SETTING: Department of Ophthalmology, Mainz University, Mainz, Germany.
METHODS: Eyes were prospectively assigned (1:1) to have biaxial microincision (<1.5 mm) phaco-emulsification or coaxial small-incision (2.8 mm) phacoemulsification
using pulsed ultrasound energy (Sovereign White Star) with variable duty cycles followed by implantation of a microincision intraocular lens. Intraoperative and postoperative complications, corrected distance visual acuity (CDVA), laser flare photometry values, www.selleckchem.com/ferroptosis.html effective phacoemulsification time (EPT), and endothelial cell count (ECC) were evaluated.
RESULTS: The study enrolled 94 eyes. There were no statistically significant differences between the techniques in intraoperative or postoperative complications. The most
frequent postoperative complications were corneal edema surrounding the incision (40%, biaxial group; 35%, coaxial group), pupil distortion (3% versus 7%), and fibrin exudation (3% versus 3%). No other postoperative complications occurred. The median EPT was statistically 8-Bromo-cAMP significantly shorter (1.34 seconds versus 5.4 seconds) and the median phaco power significantly lower (3.3% versus 12.9%) in the biaxial group than in the coaxial group (P<.001). There were no differences between groups in CDVA, laser flare photometry values, or FCC.
CONCLUSIONS: The EPT was shorter and the mean phaco power lower with biaxial phacoemulsification, perhaps because of better access of the phaco handpiece for grooving the nucleus with this technique. The 2 techniques were comparable in intraoperative and postoperative complications.”
“Study Design. Retrospective review.
Objective. To evaluate the complication rate of various types of growing spinal implants.
Summary
of Background Data. Previous studies report a complication rate of 0.38 to 1.19 per patient in growing spine surgery, but this may be an underestimate.
Methods. Medical records of 36 children with early-onset spinal deformity treated with various types of growing implants by a single surgeon were evaluated for complications. Patients with primary chest wall deformities were excluded. Complications were defined as any neurologic injuries, and any unplanned surgeries Q-VD-Oph molecular weight for implant failure or infection. Patients were separated into 3 groups: (A) standard dual growing rods, (B) hybrid growing rods with rib anchors proximally and spine anchors distally, and (C) VEPTR (vertical expandable prosthetic titanium rib). Statistical analyses were performed to compare the complication rate among the 3 groups and to evaluate the effect of Cobb angle, kyphosis, age, and body mass index on the complication rate.
Results. Mean age at initial implantation was 4.8 years; mean follow-up was 51 months (24-117 months).
