Effects of customized corneal cross-linking on higher-order aberrations in progressive keratoconus and low-grade myopia.

Objective: To evaluate the effects of customized corneal collagen cross-linking (CXL) on higher-order aberrations (HOAs) in keratoconus (KC): vertical coma (VC), horizontal coma (HC), spherical aberration (SA), trefoil (TF) and astigmatism, compared with the same effects in healthy eyes undergoing CXL for low-grade myopia.

Methods: This mixed-designed study included 38 eyes of 38 patients with KC, treated and followed prospectively, who received customized epi-on CXL in high oxygen, and a retrospective control group of 23 eyes from 23 patients who underwent central 4-mm CXL treatment for low-grade myopia. VC, HC, SA, TF and keratometry values were obtained from Pentacam HR® measurements at baseline and at 1, 6, 12 and 24 months post-treatment.

Intrauterine Tamponade Balloon for Management of Severe Postpartum Haemorrhage: Does Early Insertion Change the Outcome? A Retrospective Study on Blood Loss.

Unlabelled: The French College of Gynecologists and Obstetricians (CNGOF) recommends the use of intrauterine tamponade balloon (IUTB) in postpartum haemorrhage for bleeding that is refractory after sulprostone before either surgery or interventional radiology. However, the elapsed time between uterotonic drug injection and the insertion of intrauterine tamponade balloon was not reliably assessed.

Objective: To evaluate the role of the timing of IUTB insertion and to assess the correlation between the time of insertion and outcome.
