Background: Food protein-induced enterocolitis syndrome (FPIES) is a non-immunoglobulin E mediated food allergy that typically presents with repetitive emesis and may be associated with lethargy, marked pallor, hypotension, hypothermia, and/or diarrhea. Although many foods are known to cause FPIES, peanut-triggered FPIES is emerging due to changes in the feeding practice guidelines, which recommends early peanut introduction in infants.

Objective: We aimed to characterize peanut-triggered acute FPIES cases in our pediatric population and to describe their attributes, treatment, and outcomes.

Asthma is a heterogeneous disease characterized by chronic airway inflammation that affects more than 230 million people worldwide. Current guidelines recommend an escalating stepwise decision model for the management of asthma. However, disease control continues to be a challenge, particularly in patients with severe asthma.

Purpose: To characterize vision-related and psychosocial quality of life (QoL) parameters in medically and surgically treated patients with OSSN.

Methods: Forty-one patients with OSSN treated with medical therapy consisting of interferon alpha 2b drops 1 MIU/ml (n = 22) or who underwent surgical excision (n = 19) were contacted. All subjects answered a quality of life assessment with an original questionnaire in which they were asked about a range of parameters.

Purpose: Blue nevus is a melanocytic tumor that is commonly found in the skin. Extracutaneous presentations, including the ocular surface, are rare. As such, the purpose of this study was to characterize the clinical features and clinical course of congenital melanocytic tumor (blue nevus) of the conjunctiva.

Purpose: To evaluate the ocular surface parameters that could predict patient satisfaction after single application of vectored thermal pulsation (VTP).

Methods: This is a retrospective interventional case series; it included consecutive patients who underwent bilateral VTP for management of symptomatic meibomian gland dysfunction (MGD). Patients received a full ocular surface evaluation.

The Galapagos sea lion ( Zalophus wollebaeki ), an endangered species, experiences high pup mortality (up to 100%) in years when El Niño events reduce food supply in the Galapagos Islands. Mortality of pups in non-El Niño years is estimated to be 5% in undisturbed colonies. From 2009 to 2012 we observed high pup mortality (up to 67%) in colonies close to the Galapagos capital, Puerto Baquerizo Moreno, where contact with humans, domestic animals, and rats is frequent.

Purpose: The aim of this paper was to describe 2 cases of ocular surface squamous neoplasia (OSSN) of the conjunctiva with intracorneal and intraocular extension following intraocular surgery.

Methods: We conducted a clinical pathological retrospective case series.

Results: Case 1 underwent cataract surgery in the setting of an unnoticed adjacent OSSN.

The reactions of [γ-SiW10O36](8-) represent one of the most important synthetic gateways into a vast array of polyoxotungstate chemistry. Herein, we set about exploring the transformation of the lacunary polyoxoanion [β2-SiW11O39](8-) into [γ-SiW10O36](8-) using high-resolution electrospray mass spectrometry, density functional theory, and molecular dynamics. We show that the reaction proceeds through an unexpected {SiW9} precursor capable of undertaking a direct β → γ isomerization via a rotational transformation.

Purpose: To determine the efficacy of topical 5-fluorouracil 1% (5-FU) as a primary treatment of ocular surface squamous neoplasia (OSSN).

Design: Retrospective study.

Participants: Topical 5-FU was used as primary therapy in 44 patients with OSSN.

Article Synopsis
  • The study aimed to understand how T cells infiltrate the eyes during graft-versus-host disease (GVHD) using a specific preclinical model that mimics human transplants.
  • Researchers induced GVHD in mice through a stem cell transplant approach, examining changes in eye tissue and immune responses over time.
  • Results showed that donor T cells significantly infiltrated the eye tissues, mirroring clinical observations in patients, and this model could help explore the immune mechanisms behind ocular damage in GVHD.

In contrast to local perceptions, the impact on the local Galápagos artisanal fishery of the 16 January 2001 grounding of the Jessica and subsequent oil spill was relatively minor. No significant changes in fishing effort, total fishing catches or catch-per-unit effort were detected after the spill based on analyses of fisheries monitoring data. Nevertheless, large boats tended to move away from sites near the path of the spill following the grounding in 2001, with no fishing recorded from the oil-affected regions of Floreana and southern Isabela in February 2001.
