Comparative tomographic study of the iliac screw and the S2-alar-iliac screw in children.

Objectives: The recent advancements in spine fixation aid in the treatment of complex spinal pathologies. Both the iliac screw (IS) and the S2-alar-iliac (S2AI) screw provide adequate stability in the fixation of complex lumbosacral spine pathologies, leading to a significant increased rate of using these techniques in the daily practice of the spine surgeons. This study aims to analyze, describe, and compare the insertion and positioning parameters of the S2AI screw and IS techniques in children without spinal deformities.

Analysis of the Recurrence of Plus Disease after Intravitreal Ranibizumab as a Primary Monotherapy for Severe Retinopathy of Prematurity.

Purpose: To assess the outcomes of severe retinopathy of prematurity (ROP) in zone I or posterior zone II, and of aggressive posterior ROP treated with a single dose of intravitreal ranibizumab (IVR) as monotherapy.

Design: Retrospective study.

Participants: The study included premature babies diagnosed with aggressive posterior ROP or ROP 3+ in zone I or posterior zone II.

Intravitreal ranibizumab as a primary or a combined treatment for severe retinopathy of prematurity.

Purpose: The aim of the study was to assess the outcomes of severe retinopathy of prematurity (ROP) in zone I or posterior zone II treated with intravitreal ranibizumab (IVR) as monotherapy or combined treatment with laser photocoagulation.

Methods: This is a retrospective study analyzing clinical records of the included patients. Patients were divided into two groups: group 1 included patients who received only IVR treatment; and group 2 was subdivided into group 2A - including patients with IVR as initial treatment and complementary laser photocoagulation if retinal neovascularization or plus disease did not regress, and group 2B - including patients with initial laser photocoagulation and IVR as rescue therapy.

Intravitreal bevacizumab at 4-month intervals for prevention of macular edema after plaque radiotherapy of uveal melanoma.

Purpose: To evaluate the efficacy of intravitreal bevacizumab for prevention of macular edema after plaque radiotherapy of uveal melanoma.

Design: Retrospective, single-center, nonrandomized, interventional comparative study.

Participants: Patients with uveal melanoma treated with plaque radiotherapy were divided into 2 groups: a bevacizumab group and a control group.

Intravenous chemoreduction or intra-arterial chemotherapy for cavitary retinoblastoma: long-term results.

Objective: To assess the long-term results of chemotherapy for cavitary retinoblastoma.

Methods: Retrospective, nonrandomized, interventional case series of 26 cavitary retinoblastomas in 25 eyes of 24 patients. Retinoblastomas were treated with intravenous chemoreduction and/or intra-arterial chemotherapy.
