RESUMO
Transjugular intrahepatic portosystemic shunts (TIPS) are used to manage multiple complications of portal hypertension. Accounts of infection of TIPS stents are uncommon. The literature reports two cases of TIPS-associated Torulopsis glabrata (Candida glabrata) fungemia; both patients died within a year of TIPS placement despite therapy with intravenous antifungal agents. This report describes the successful long-term survival of a patient with Torulopsis TIPS stent infection.

Infrared and Raman spectra were recorded for cis-3,4-difluorocyclobutene (cDFCB) and trans-3,4-difluorocyclobutene-d4. Unscaled density functional theory (DFT) calculations of frequencies and intensities at the B3LYP/6-311++G(d,p) level supported the complete assignment of the vibrational fundamentals. The previous assignment of fundamentals of trans-3,4-difluorocyclobutene was revised. An unusual blue shift occurs for the methylenic CH-stretching frequencies of cis-3,4-difluorocyclobutene in going from the gas phase to the liquid phase. This hydrogen bond effect is related to similar observations recently reported and interpreted. The blue shift does not occur for the vinylic CH bonds of the cis isomer and does not occur for either type of CH bond in the trans isomer.
