[Show abstract][Hide abstract] ABSTRACT: Initiation of dialysis on Sunday is limited by constraints that do not exist on other days of the week, which may lead to triaging of dialysis therapy. The study hypothesis was that patients with AKI on a Sunday would sustain higher mortality rates.
Study participants (n=4970) were part of the retrospective University of Pennsylvania Health AKI cohort, which is composed of patients with severe inpatient AKI (characterized by a doubling of admission creatinine) who were hospitalized from January 1, 2004, to August 31, 2010. Patient-days (n=15,995) were included if the patient had AKI severity of Acute Kidney Injury Network (AKIN) stage 2 or greater and had not yet begun receiving dialysis. The association of day of the week and inpatient mortality was assessed with logistic regression of data updated daily, using robust variance estimators.
The rate (95% confidence interval [CI]) of initiation of dialysis on Sunday was 2.5 (1.8 to 3.1) per 100 patient-days, compared with 3.8 (3.5 to 4.1) per 100 patient-days on other days of the week (P=0.001). Inpatient mortality (95% CI) among patients with severe AKI present on a Sunday was 30% (28% to 32%), compared with 31% (31% to 32%) on other days of the week (P=0.08). Inpatient mortality among patients who initiated dialysis on Sunday was 65% (52% to 79%), compared with 65% (61% to 70%) among those who initiated dialysis from Tuesday through Saturday (P=0.79). Patients who initiated dialysis on Monday had a lower mortality than those who initiated it on another day of the week (52% [40% to 64%] versus 65% [61% to 70%]; P=0.03).
Despite a lower frequency of dialysis, patients with severe AKI on Sunday have mortality similar to that of patients with severe AKI on other days of the week.

[Show abstract][Hide abstract] ABSTRACT: Argyria is a rare cutaneous manifestation of silver deposits in the skin, characterized by a grayish blue discoloration, particularly in sun-exposed areas. We report the case of a patient with a history of schizoaffective disorder and type 2 diabetes mellitus who presented with argyria of the face and neck. The patient had a history of ingesting colloidal silver proteins (CSPs) for approximately 10 years as a self-prescribed remedy for his medical conditions. Colloidal silver protein has gained popularity among patients who seek alternative medical therapies. Argyria is the most predominant manifestation of silver toxicity. It is unclear if our patient began taking CSP because of his schizoaffective disorder or if silver toxicity may have induced somatic delusions; however, it is important for physicians to have a thorough understanding of alternative therapies on the market. We present a detailed background on silver ingestion and its systemic effects.
