Reproductive health among women of child-bearing age after surgery for rheumatic heart disease in Rwanda.

Objective: To determine maternal and fetal outcomes in postoperative women with rheumatic heart disease who become pregnant after valve surgery and evaluate current anticoagulation management during pregnancy.

Methods: Data from the Rwandan rheumatic heart disease cardiac surgical registry identified all female patients who underwent valve surgery before or during childbearing age since 2006. In total, 136 participants completed a mixed-methods questionnaire detailing each pregnancy after surgery, including anticoagulation regimen and outcomes.

Interruption of the tricuspid regurgitant jet: A possible consequence of reflected waves.

Reflected pressure waves can impact central aortic pressure, and can cause notching of the pulmonic valve Doppler signal. However, reflected waves in the venous system usually do not achieve a high enough velocity to alter Doppler flow patterns. Herein we report a case of systolic notching of the tricuspid regurgitant signal that likely resulted from reflected venous waves.

Pediatric Resident Communication of Hospital Discharge Instructions.

Objective: Suboptimal provider-parent communication contributes to poor parent comprehension of pediatric discharge instructions, which can lead to adverse outcomes. Residency is a critical window to acquire and learn to utilize key communication skills, potentially supported by formal training programs or visual reminders. Few studies have examined resident counseling practices or predictors of counseling quality.

Surgical management of a collateral arch channel and aortic coarctation.

Background: The atretic connection between the left fourth and sixth aortic arches is a rare congenital cardiac anomaly with controversial debates on its origin. This anatomy has been previously reported with additional cardiac anomalies of maldevelopment.

Aims: We present the successful surgical management of a 3-month-old female with Cornelia de Lange syndrome and coarctation of the aorta in the setting of this unique collateral channel.

Frequency of varicella zoster virus DNA in human adrenal glands.

Varicella zoster virus (VZV) becomes latent in ganglionic neurons derived from neural crest cells. Because the adrenal gland also contains medullary chromaffin cells of neural crest origin, we examined human adrenal glands and medullary chromaffin cell tumors (pheochromocytomas) for VZV and herpes simplex virus type 1 (HSV-1). We found VZV, but not HSV-1, DNA in 4/63 (6 %) normal adrenal glands.
