Less invasive pilonidal sinus surgical procedures

R. E. Andersson

coloproctology > 2019 > 41 > 2 > 117-120

Pilonidal disease can be treated by less invasive methods such as simple mechanical cleansing of the sinus and cavity of hairs and granulation tissue eventually supplemented by filling the space with an antiseptic or sclerosing agent like phenol (forbidden in Germany due to its toxicity) or space-holding fibrin glue. Minimal excision or debridement of the sinus and/or cavity through a midline or a separate...

Weili Hu, Jung Eun Kim

Molecular Nutrition & Food Research > 68 > 12 > n/a - n/a

Scope Xanthophylls, vital for ocular defense against blue light and reactive oxygen species, are prone to oxidative degradation; however, they may be regenerated antioxidant‐rich plant phenols. Despite certain in vitro evidence, clinical studies show inconsistent findings and this may be due to varying phenolic reduction potentials. Therefore, the current study aims to investigate the ocular protective...
