Emergency medicine pharmacotherapy compromises accuracy of plasma creatinine determination by enzyme-based methods: real-world clinical evidence and implications for clinical practice.

Background: Assessment of kidney function in emergency settings is essential across all medical subspecialties. Daily assessment of patient creatinine results from emergency medical services showed that some deviated from expected values, implying drug-related interference.

Methods: Real-time clinical evaluation of an enzyme method (Roche CREP2) in comparison with the Jaffé gen.

Acute kidney injury requiring renal replacement therapy due to Clostridioides difficile infection in a 15-year-old boy.

Acute gastroenteritis is commonly seen in pediatric clinical practice. It is a largely self-limited disease with a benign course. We present a case of teenager with gastroenteritis resulting in severe acute kidney injury.

Novel mutations in TRPM6 gene associated with primary hypomagnesemia with secondary hypocalcemia. Case report.

Background: Primary hypomagnesemia with secondary hypocalcemia (HSH) is a rare genetic disorder. Dysfunctional transient receptor potential melastatin 6 causes impaired intestinal absorption of magnesium, leading to low serum levels accompanied by hypocalcemia. Typical signs at initial manifestation are generalized seizures, tetany, and/or muscle spasms.

Spindle Cell Hemangioma and Atypically Localized Juxtaglomerular Cell Tumor in a Patient with Hereditary BRIP1 Mutation: A Case Report.

Spindle cell hemangioma is a benign vascular tumor typically occurring in the dermis or subcutis of distal extremities as red-brown lesions that can grow in both size and number over time. They can be very painful and potentially disabling. A family history of cancer or previous history may be relevant and must be taken into consideration.

Juxtaglomerular cell tumor--a rare cause of secondary hypertension.

Secondary hypertension (SH) is much more common in children than in adults. We report a 17-year-old girl with severe hypertension, hypokalemia and metabolic alkalosis. Because of these findings, primary or secondary hyperaldosteronism was suspected.
