A case of recurrent peritoneal dialysis-related peritonitis caused by Stenotrophomonas maltophilia during ongoing antibiotic treatment for Enterococcus faecalis-induced peritonitis.

Recurrent peritonitis is a serious complication of peritoneal dialysis (PD), which could result in PD withdrawal and mortality. However, cases of recurrent peritonitis occurring during ongoing antimicrobial therapy are rarely reported. Herein, we present a 71-year-old man who experienced initial peritonitis due to Enterococcus faecalis.

Usefulness of aliasing phenomenon for diagnosing venous valve stenosis of arteriovenous fistula in a hemodialysis patient.

We present venous valve stenosis, which is an uncommon cause of arteriovenous fistula (AVF) dysfunction. Owing to the thin structure in echography, venous valves are challenging to observe; however, we have found that the aliasing phenomenon is useful for diagnosing venous valve stenosis.

Phenotypic differences of mutation-negative cases in Gitelman syndrome clinically diagnosed in adulthood.

Gitelman syndrome (GS), an autosomal recessive kidney disorder, is characterized by hypokalemia, hypomagnesemia, hypocalciuria, and metabolic alkalosis. Generally, diagnosis is made in school-aged children but multiple cases have been diagnosed in adulthood. This study examines the phenotypic differences between genetically confirmed cases and mutation-negative cases in adults.

Highly selective sorption of small unsaturated hydrocarbons by nonporous flexible framework with silver ion.

Ag2[Cr3O(OOCC2H5)6(H2O)3]2[alpha-SiW12O40] [1] is a nonporous flexible ionic crystal composed of 2D-layers of polyoxometalates ([alpha-SiW12O40](4-)) and macrocations ([Cr3O(OOCC2H5)6(H2O)3](+)) stacking along the b-axis. The silver ions are located in the vicinity of the oxygen atoms of the polyoxometalates. The sorption amounts of small unsaturated hydrocarbons such as ethylene, propylene, n-butene, acetylene, and methyl acetylene into 1 are comparable to or larger than 1.
