Conservative management of perforated duodenal diverticulum: A case report and review of the literature

World Journal of Gastroenterology 2008年第12期14卷 1949-1951页

Duodenal diverticula are a relatively common condition. They are asymptomatic, unless they become complicated, with perforation being the rarest but most severe complication. Surgical treatment is the most frequently performed approach. We report the case of a patient with a perforated duodenal diverticulum, which was diagnosed early and treated conservatively with antibiotics and percutaneous drainage of secondary retroperitoneal abscesses. We suggest this method could be an acceptable option for the management of similar cases, provided that the patient is in good general condition and without septic signs.

Objective： To evaluate the effect of chitosan （CH） and hydrogen peroxide （H2O） seed coatings and seedling sprinklings on two different maize varieties by measuring their phenology, the H202 presence, the catalase （CAT） activity, and the protein quantity. Methods： Seven groups of ten seeds for each maize variety were treated with CH （2% （20 g/L） and 0.2% （2 g/L）） or H2O2 （8 mmol/L） by coating, sprinkling, or both. Germination and seedling growth were measured. One month after germination, the presence of H202 in seedlings in the coated seed treatments was evaluated. Protein content and CAT activity were determined under all treatments. Results： H2O2 seed coating en- hanced the germination rate and increased seedling and stem length in the quality protein maize （QPM） variety. Seedlings had a higher emergence velocity under this treatment in both varieties. CH and H2O2 sprinklings did not have an effect on seedling phenology. Exogenous application of H2O2 promoted an increase of endogenousH2O2. OH and H2O2seedling sprinkling increased the protein content in both maize varieties, while there was no significant effect on the CAT activity of treated seeds and seedlings. Conclusions： CH and H2O2 enhance some phenological and biochemical features of maize depending on their method of application.
