The use of single-stapling techniques reduces anastomotic complications in minimal-invasive rectal surgery.

Background: Leakage of rectal anastomoses is one of the most important and feared complications in colorectal surgery. Apart from patient-specific risk factors, technical aspects may influence the occurrence of anastomotic complications. This study investigated whether using single-stapling techniques (SST) instead of the double-stapling technique (DST) for minimal-invasive rectal anastomosis is associated with a lower rate of anastomotic complications.

Optimizing photo-mineralization of aqueous methyl orange by nano-ZnO catalyst under simulated natural conditions.

Background: Photo-degradation of organic contaminants into non-hazardous mineral compounds is emerging as a strategy to purify water and environment. Tremendous research is being done using direct solar light for these purposes. In this paper we report on optimum conditions for complete mineralization of aqueous methyl orange using lab-prepared ZnO nanopowder catalyst under simulated solar light.

Recurrent sterile arthritis following primary septic meningococcal arthritis.

Primary septic meningococcal arthritis (PSMA) is an unusual manifestation of meningococcal disease. With appropriate antibiotic therapy, complete recovery is the rule. A "postinfectious arthritis" in the previously infected joint may ensue, however.
