Immunobiotic and Paraprobiotic Potential Effect of in a Systemic Toxoplasmosis Murine Model.

One of the main characteristics of probiotics is their ability to stimulate and modulate the immune response regardless of their viability. (Lc) can stimulate local and systemic immunity, in addition to the activation of macrophages at sites distant from the intestine. Activated macrophages limit the replication of intracellular protozoa, such as , through the production of nitric oxide.

Steam roller maneuver in pneumatic retinopexy. Does it work?

Objective: To identify the efficacy and safety of the steam-roller maneuver, in patients treated with pneumatic retinopexy.

Method: Experimental, prospective, comparative, longitudinal study in patients with retinal detachment, treated with pneumatic retinopexy. Patients were assigned to one of two groups: without steam roller maneuver (group 1) or with it (group 2).

Correlation of transforming growth factor β-1 vitreous levels with clinical severity of proliferative vitreoretinopathy in patients with rhegmatogenous retinal detachment.

Objective: To correlate the vitreous concentration of transforming growth factor β-1 (TGF β-1) with the degree of clinical severity of proliferative vitreoretinopathy (PVR).

Design: A prospective, observational, cross-sectional study carried out on cases and controls.

Participants: The study included 40 patients with a diagnosis of PVR secondary to rhegmatogenous retinal detachment.

Dexamethasone implant in silicone oil: in vitro behavior.

Background: To determine the effect of the silicone on the dexamethasone intravitreal implant.

Methods: Basic, experimental, prospective and transversal study performed at the hospital "Nuestra Señora de la Luz" in Mexico City. One dexamethasone implant was placed in a test tube with 4 mL of each tamponade medium: 1000cS, 5000cS and heavy silicone oil; basic saline solution was used as the control medium.

Cicatricial changes in ocular pemphigus.

Purpose: To describe the clinical characteristics of ocular involvement in patients with pemphigus at an ophthalmological referral center.

Methods: A retrospective review was conducted on patients with the immunopathological diagnosis of pemphigus examined between 1 January 2000 and 1 April 2010. Uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (BCVA), ocular symptoms, and ocular surface inflammatory and scarring changes were assessed.
