Résumé
A novel simulation model (without using human corneas) has been described for understanding the surgical concepts and developing tactile reflexes of Descemet membrane (DM) endothelium scroll manipulation and orientation in the anterior chamber, which are necessary for performing Descemet membrane endothelial keratoplasty (DMEK). Termed the “DMEK aquarium,” this model helps facilitate the understanding of different maneuvers of the DM graft needed inside the fluid-filled anterior chamber, like unrolling or unfolding, flipping or inversion, and checking orientation and centration in the host cornea. A stepwise plan for surgeons starting to learn DMEK utilizing various available resources is also suggested.
Résumé
This article reports a novel surgical technique of partial-thickness compression sutures without descemetopexy with air or gas for the management of acute hydrops in keratoconus. Two patients presented with localized corneal edema with a Descemet membrane (DM) tear in the left eye. Tomography of the right eye revealed localized steepening with increased maximum keratometry and decreased central pachymetry. They were diagnosed with keratoconus in the right eye and acute corneal hydrops (ACH) in the left eye. Compression sutures were passed through the stroma without touching the DM. The anterior chamber was not entered at all at any point during the surgery. Resolution of edema was noted intraoperatively itself. Further resolution of edema was noted from the first postoperative day which markedly reduced within the first week. A corneal scar with no edema was seen at six weeks. In both the patients, vision at presentation was counting fingers close to face which improved to 20/60 and 20/50, respectively, at the last visit.
Résumé
The present study describes in- vitro efficacy of Emblica officinalis against Methicillin Resistant S. aureus mastitis. Diffusion technique was used to assess in-vitro efficacy of Emblica officinalis. Zone of inhibition was measured and used to compare the in-vitro efficacy. The zone ranged between 10-13 mm with maximum zone of 13 mm observed in 200 and 225 mg/ml DMSO disc, followed by 12 mm in 175 and 150 mg/ml DMSO disc, 11 mm in 125 mg/ml DMSO disc and 10 mm in 100 mg/ml DMSO disc. The results indicate that the sensitivity pattern for Emblica officinalis at 200 & 175 mg/ml DMSO concentration and was comparable with the standard antibiotics in Methicillin sensitive S. aureus. In Methicillin resistant S. aureus isolates, the zone of inhibition was in the order Oxytetracycline (15mm) followed by Emblica officinalis -200 (13 mm) and Methicillin, ampicillin, gentamicin, ofloxacin were resistance
