Barriers to Care Among Glaucoma Patients With a Missed Appointment and Interest in a Navigator Program.

Prcis: Most glaucoma patients with missed appointments report barriers to care and social risk factors. One third expressed interest in engaging with a patient navigator program. Most expressed interest in rescheduling.

Tissue distribution of ethanol after intraprostatic injection using a porous needle.

Purpose: To develop a safe and precise method for intraprostatic injection, and to establish correlation between the volume of ethanol injectate and the volume of subsequent infiltrated prostate tissue.

Materials And Methods: We performed intraprostatic injection of 96% ethanol using a needle which has a segment of its wall made of capillary membrane with hundreds of pores in an acute and chronic canine experiment, in heart-beating cadaveric organ donors, and in a xenograft model of human prostate cancer. Whole mount tissue sections were used for three-dimensional reconstruction of the necrotic lesions and calculation of their volumes.

Validation of a new rat model of urethral sphincter injury and leak point pressure measurements.

Aims: experiments were performed to establish and validate a rat model of urethral sphincter injury and to develop a method for leak point pressure (LPP) measurements performed repeatedly in the same animal.

Methods: Twenty-four Sprague-Dawley female rats underwent bladder and epidural catheter implantation. Five days later, cystometry was performed using continuous infusion.
