SARS-CoV-2 contact searching for between deprived people through epidemic durations needs to be a priority approach: comes from an airplane pilot experiment inside Barcelona.
According to SIAR mixing model, sedimentary OM of Pina Sound is composed of, on average 50% phytoplankton, 24% sewage and 26% C3 plants. This reflects fertilization of Pina Sound with high loads of untreated sewage. Pina Sound has a great potential to retain sewage-derived OM.Usually, stability conditions of excavation slopes are evaluated by means of kinematic analysis and geomechanical classification systems. However, field surveys are concentrated at the slope toe and information about the upper and internal portions of rock masses are not taken into account. In order to tackle with these issues multisources data were integrated. The studies were carried out in a marble quarry located in one of the largest Brazilian poles of dimension stones. Results have shown that drone images actually help in the structural characterization of rock masses because they allow to classify variable degrees of fracturing and to identify structural domains in the entire slope face. In addition, the number of discontinuities interpreted from drone images was much larger than that determined by scanline survey methods. This demonstrates that the subsampling of classical survey methods may significantly affect slope stability assessment. Results have also shown that the intensive use of explosives as a method for rock dismantling was an important mechanism of fracture generation. The electrical resistivity tomography method coupled with the other survey methods employed in this work, proved an important tool for rock mass characterization and quarry exploitation, since it allowed identifying and assessing subsurface fractured zone.This research study was developed in the Ribeirão dos Macacos basin at the district of Nova Lima, Minas Gerais state, Brazil. The information value statistical method was applied in the construction of the landslide susceptibility map at the 125,000 scale. Different partitions of the inventory were tested, as well as different landslide predisposing factors. In the construction of the landslide inventory, the south, southeast and south-west slopes generally present a higher quality in aerial / orbital images due to the position of the sun (lighting direction), which emphasizes the surface structures and it may omit old landslides on slopes facing north, northeast, and northwest. This condition can generate misleading models when using the slope aspect. Another verification was that the models with better Area Under the Curve index will not always restrict the high susceptibility class in smaller areas. This incongruence occurs due to the different curve conformations, since a smaller index curve can present more restrictive results than a larger index curve. The results showed that the model has a high capacity of adjustment to the input data and high landslide predictive capacity.This article reports a combined technique of sutureless intrascleral fixated intraocular lens implantation and Descemet membrane endothelial keratoplasty in a patient with anterior pseudophakic bullous keratopathy. Two scleral tunnels were created, corneal incisions were made, and a foldable intraocular lens was cut and removed from the anterior chamber. After performing anterior vitrectomy, a 3-piece foldable intraocular lens was implanted into the anterior chamber. One of the intraocular lens haptics was grasped with a forceps and pulled out from the scleral tunnel. Then, the end of the haptic was cauterized. Similar maneuvers were applied for the other haptic. Next, an 8-mm-diameter donor tissue was prepared, and the recipient endothelial tissue was peeled and removed from the center of the recipient cornea. The prepared donor tissue was injected into the anterior chamber. After proper opening and placement of the donor tissue, an air bubble was injected below the tissue. There were no postoperative complications during the 1-month follow-up.Central giant cell granuloma is a rare osseous tumor affecting young patients with anatomical and functional compromise of the maxilla and mandible. check details Steroid injection therapy constitutes a less invasive treatment modality for disease control in selected cases. Retinal ischemia is a reported complication of multiple medical procedures, including dental interventions, and may lead to loss of vision with poor prognosis. We report a case of retinal arteriolar ischemic disease following central giant cell granuloma management with local injected corticosteroids.Corneal ectasia is one of the main complications of keratorefractive procedures. In this report, we describe a case of corneal ectasia after laser-assisted in situ keratomileusis), which progressed with acute hydrops and aqueous leakage and required a suture for correction.A 65-year-old female patient was referred to our hospital for evaluation for cataract surgery. Her past medical history included corrective jaw surgeries for facial deformities that developed during infancy and persisted through early adulthood. A complete ophthalmological examination revealed bilateral angioid streaks, drusen in both optic disc areas, and a subretinal neovascular membrane in the left macula. Genetic analysis revealed a mutation in the SH3BP2 gene compatible with the diagnosis of cherubism. Clinical and laboratory evaluation revealed no additional systemic disorders. Cherubism is a rare disease characterized by the development of painless fibro-osseous lesions in the jaws and the maxilla in early childhood. Ophthalmologic findings in this disease are primarily related to orbital bone involvement. This is the first report of AS and optic disc drusen in a patient diagnosed with cherubism. Our findings suggest that angioid streaks and optic disk drusen should be included in the differential diagnosis of ophthalmic disorders identified in patients with this genetic abnormality.
To compare visual acuity, macular thickness, and the area of active neovascularization based on fluorescein angiography outcomes associated with standard single-spot panretinal photocoagulation in the Early Treatment Diabetic Retinopathy Study (ETDRS) pattern combined with intravitreal ranibizumab injection versus multiple-spot full scatter (PASCAL) panretinal photocoagulation combined with intravitreal ranibizumab injection versus intravitreal injection alone in patients with proliferative diabetic retinopathy.

Patients with proliferative diabetic retinopathy and no prior laser treatment were randomly assigned to receive three different types of treatment. Panretinal photocoagulation in the ETDRS group was administered in two sessions (weeks 0 and 2), and panretinal photocoagulation in the PASCAL group was administered in one session (week 0). Intravitreal injection of ranibizumab was administered at the end of the first laser session in both the ETDRS and PASCAL groups and at week 0 in the intravitreal injection group.
