Mobile unidirectional airflow device reduces air contamination in an intravitreal outpatient clean room setting.

Purpose: To evaluate and compare the mycobacterial load using a mobile laminar airflow (LAF) device in an IVI-dedicated outpatient clean room (OCR) without ventilation systems and in a hospital-based operating theatre (HOT).

Methods: This case-control study was conducted in 2 different settings: OCR and HOT during a series of intravitreal injections (IVIs). The Air Microbial analysis was performed using a Surface Air System instrument at three different moments during the IVI sessions in both settings: at the operative site (OS), four meters from the OS (DOS) and in the disinfection room (DR).

Optic disc pit maculopathy: Covering or filling technique with human amniotic membrane patch to treat the optic disc pit maculopathy?

Purpose: To describe two patients affected by optic disk pit-maculopathy ODP-M surgically treated with pars-plana vitrectomy (PPV) and the apposition of a human Amniotic Membrane (hAM) patch.

Methods: Patients underwent a PPV with the apposition of a hAM patch to cover the ODP. In case 1, a 2 surgery was necessary to push the hAM patch inside the pit, whereas in case 2 the patch was pulled inside the pit following the pressure gradient when infusion was turned on.

Choroidal vascularity analysis in patients with juvenile idiopathic arthritis without acute uveitis.

Objectives: We aimed to investigate choroidal involvement and the degree of anterior chamber inflammation in a cohort of patients with juvenile idiopathic arthritis (JIA) without clinical signs of active uveitis and to compare it with healthy controls (HC).

Methods: Enhanced-depth imaging optical coherence tomography (EDI-OCT) scans of 21 patients diagnosed with JIA and 22 HC of equal age were acquired. Images were binarised to measure subfoveal choroidal thickness (SCT), nasal choroidal thickness (NCT), temporal choroidal thickness (TCT), total choroidal area (TCA), luminal area (LA), stromal area (SA) and choroidal vascular index (CVI).

New Biocide Based on Tributyltin(IV) Ferulate-Loaded Halloysite Nanotubes for Preserving Historical Paper Artworks.

Combining biologically active compounds with nanocarriers is an emerging and promising strategy for enhancing the activities of molecules while reducing their levels of toxicity. Green nanomaterials have recently gained momentum in developing protocols for treating and preserving artifacts. In this study, we designed a functional biohybrid material by incorporating tributyltin(IV) ferulate (TBT-F) into halloysite nanotubes (HNTs), generating a new formulation called HNT/TBT-F.
