Purpose: To investigate the incidence, management, and outcomes of eyes with active uveitis central serous chorioretinopathy (CSCR). Methods: Retrospective chart review Results: Of 4,034 patients diagnosed during 8-year study period, 20 (0.5%) had comorbid CSCR, followed for a median 34 months. Patients were stratified based on diagnoses sequence. In Cohort 1, 4 (3 patients) initially later developed CSCR at 65 days following corticosteroid initiation, resolution occurring in all 104 after...
Background Accurate and precise methods to predict growth remain lacking. Diffusion tensor imaging (DTI) depicts the columnar structure of physis metaphyseal spongiosa provides measures tract volume length that may help growth. Purpose To validate physeal DTI metrics as predictors height velocity (1-year gain from time MRI examination) total (height examination until stops) compare prediction accuracy with bone age–based models. Materials Methods Femoral studies (b values = 0 600 sec/mm2;...
The multiple CF bond character of PhCFMe (+) ions has been examined by means theory, vibrational spectroscopy the gaseous ions, and unimolecular decomposition chemistry. Atoms in Molecules analysis DFT wave functions gives a order n = 1.25 (as compared with 1.38 for Me 2CF (+), relative to 1 fluoromethane 2 diatomic (+)), which is consistent calculations adiabatic stretching frequencies (nu CF). Experimental gas phase IR spectra, recorded resonant multiphoton dissociation (IRMPD) using...
The thermal chemistry of cis- and trans-1,4-difluoro-2-butenes on Pt(111) single-crystal surfaces was characterized by temperature programmed desorption (TPD) reflection−absorption infrared spectroscopy (RAIRS). study motivated the possibility differentiating two isomers directly mass spectrometry, something that is not possible with nonfluorinated olefins. On clean surface a preference identified for conversion cis isomer to its trans counterpart, opposite what had been previously reported...
Diffusion tensor imaging of physis and metaphysis can be used as a biomarker to predict height change in the pediatric population. Current application this technique requires manual segmentation which is time-consuming introduces interobserver variability. UNET Transformers (UNETR) for automatic optimize workflow. Three hundred eighty-five DTI scans from 191 subjects with mean age 12.6 years ± 2.01 were retrospectively training validation. The Dice correlation coefficient was 0.81 UNETR...
Concerted unimolecular eliminations from ionized sec-alkyl aryl ethers (ROAr+•) display a preference for producing double bonds with trans geometry. This can be assessed quantitatively, provided that regioselective variant found. Expulsion of neutral alkenes via syn-elimination to give ArOH does not exhibit pronounced regard the direction elimination. By contrast, 2-hexyl p-trifluoromethylphenyl ether eliminates regioselectively, giving 2-hexenes rather than 1-hexene. Vicinally...
Background: Retrospective cohort study of 561 adult patients undergoing secondary intraocular lens (IOL) implantation by vitreoretinal surgeons at a single institution from April 2015-December 2020. Methods: Patient historical factors, intraoperative/postoperative complications, and outcomes IOL type (anterior chamber (ACIOL) vs scleral sutured (SSIOL) fixated (SFIOL) sulcus) were assessed. Primary rates postoperative retinal tears rhegmatogenous detachment (RRD). Secondary intraoperative...
PurposeTo evaluate clinical features and outcomes associated with degree of tumor pigmentation in patients uveal melanoma (UM) the choroid ciliary body.DesignRetrospective observational study.Subjects6,934 consecutive choroidal or body between 1971 2007 from a single ocular oncology center.MethodsData on patient demographics, characteristics, treatment approach, were collected. Comparisons pigmented (>80% by surface area), partially (20-80%), non-pigmented tumors (<20%) performed using...
Osteosarcoma is the most common primary bone tumor in children. While humerus 3rd anatomic location, it site for fractures. Our objective to characterize MRI features of osteosarcoma children and with respect risk sustaining a pathologic fracture. Children histologically confirmed osteosarcoma, who underwent pre-operative (2008-2023) were included. Two radiologists retrospectively reviewed all MRIs determine medullary (skip lesions trans-epiphyseal tumor), joint, extraosseous (muscle,...
Determination and longitudinal monitoring of progressive skeletal maturity are essential in the management children with scoliosis. Although different methods for determining exists, most widely practiced method relies on ossification pattern bones hand wrist, which is traditionally acquired using conventional techniques after acquisition spine low-dose slot-scanning technique. Whereas existing published literature has promising results use technique to acquire these wrist radiographs, image...
Type of Case: The fabrication provisional prostheses is a treatment modality that used to support and develop soft‐tissue contours improved health dental implant site before final restoration. use restoration may improve the esthetics allow evaluation crown anatomy interface. Developing soft tissue in phase allows practitioner, patient, laboratory technician evaluate potential for achieving desired outcome. This paper contrasts two predominant methods fabricating restorations assesses their...
Abstract Purpose: Our study describes the racial/ethnic composition and broad health status/severity of disease cohorts Diabetic Retinopathy Clinical Research (DRCR) clinical trials compares rates non-completion trial to first data report (lost follow up (LTFU)). Methods: This is a retrospective cohort participants in Retina Network that met our inclusion criteria. The primary outcome was lost their associated risk factors. Results: Eight with 3492 Participants who were LTFU more likely...
