Neonatal aortic dilatation secondary to vitamin A deficiency.

We report on a term neonate with unexplained respiratory distress, dilatation of the descending aorta, and low serum retinol concentration. The respiratory distress did not respond to conventional medical management and persisted for 22 days requiring an inspired oxygen fraction of 0.4 to 0.

Stress predicts the trajectory of wound healing in living kidney donors as measured by high-resolution ultrasound.

Background: Psychological stress has been shown to be an influential factor on the rate of wound healing; however these findings have been demonstrated predominantly on artificially created wounds. Due to the absence of major co-morbidities, living kidney donors are a unique group in which to study this relationship. This study investigated the effect of preoperative stress and personality on surgical wound healing through the use of high-resolution ultrasound.

Prevalence, patterns of treatment, and control of hypertension in predialysis patients with chronic kidney disease.

Background/aims: Data on the prevalence, treatment and control of hypertension in patients with advanced chronic kidney disease (CKD) are limited. This study aimed to examine the above factors in a cohort of predialysis patients.

Methods: During a period of 4 months, we recorded information on blood pressure (BP), comorbidities, medications and related parameters of patients followed up in the Low-Clearance Clinic of our Department.

Prevalence and factors associated with hyperkalemia in predialysis patients followed in a low-clearance clinic.

Background And Objectives: Recent studies evaluated the prevalence of hyperkalemia and related risk factors in patients with CKD of various stages, but there is limited relevant information in predialysis patients. This study aimed to examine the prevalence and factors associated with hyperkalemia in the structured environment of a low-clearance clinic.

Design, Setting, Participants, & Measurements: In a cross-sectional fashion over a prespecified period of 4 months, information on serum potassium and relevant laboratory variables, comorbidities, medications, and dietician input in patients with advanced CKD under follow-up in the low-clearance clinic of our department was recorded.
