[A case of isolated small intestinal wall calcification on patient with continuous ambulatory peritoneal dialysis].

The metastatic calcification is defined as the deposition of calcium salt in normal tissue with an abnormal serum biochemical environment, such as chronic kidney disease, hyperparathyroidism, and hypercalcemia related with malignancy. Although the metastatic calcification can develop in any organs and tissues, presenting its symptoms and complications are rare. Thus a few cases have been reported.

Unintended cannulation of the subclavian artery in a 65-year-old-female for temporary hemodialysis vascular access: management and prevention.

Ultrasound-guided cannulation of a large-bore catheter into the internal jugular vein was performed to provide temporary hemodialysis vascular access for uremia in a 65-yr-old woman with acute renal failure and sepsis superimposed on chronic renal failure. Despite the absence of any clinical evidence such as bleeding or hematoma during the procedure, a chest x-ray and computed tomographic angiogram of the neck showed that the catheter had inadvertently been inserted into the subclavian artery. Without immediately removing the catheter and applying manual external compression, the arterial misplacement of the hemodialysis catheter was successfully managed by open surgical repair.

Local steroid injection via the cricothyroid membrane in patients with a vocal nodule.

Objective: To analyze the usefulness and safety of a steroid injection into vocal nodules via the cricothyroid membrane. Local administration of steroid directly into the larynx has been reported in many laryngeal diseases with different methods.

Design: Prospective case series at an academic tertiary care hospital.
