Viewing an educational video can improve phosphorus control in patients on hemodialysis: a pilot study.

Unlabelled: The objective of this single-arm interventional pilot study was to determine whether viewing an educational video about phosphorous and phosphorous control by patients on hemodialysis was associated with improved phosphorous values and improvement in knowledge and attitudes about the topics presented.

Method: An educational video was shown to 150 patients at 16 dialysis centers. The change in serum phosphate levels before and after the viewing of an educational video was evaluated.

Autoimmune sensorineural hearing loss: clinical course and treatment outcome.

Background: Autoimmune sensorineural hearing loss (ASHL) originally was defined both by the presence of progressive hearing loss (with or without vertigo) and a positive response to glucocorticoid therapy. Subsequently, antibodies to a 68-kd inner-ear antigen were identified in a high percentage of patients with ASHL.

Objective: To analyze the disease progression and treatment outcome of ASHL.

Efficacy of porcine gonadotropins for repeated stimulation of ovarian activity for oocyte retrieval and in vitro embryo production and cryopreservation in Siberian tigers (Panthera tigris altaica).

A comparison of the amino acid sequences demonstrated that Siberian tiger gonadotropins are more homologous with those of porcine than any other commercially available preparation. The present study measured the efficacy of repeated ovarian stimulation with purified porcine gonadotropins on the follicular, hormonal, and immunogenic responses in Siberian tigers as well as on the ability of oocytes retrieved by laparoscopic follicular aspiration to fertilize and cleave in vitro. Controlled rate and vitrification cryopreservation methods were also compared for their ability to support ongoing cleavage following thawing of presumptive 2- to 4-cell tiger embryos generated in vitro.
