AIM:To compare the natural history and course of acute diverticulitis in a younger age group with an older population and to evaluate whether younger patients should be managed differently. METHODS:This study was a retrospective review of 157 patients treated with acute diverticulitis between January 1,2004 and December 31,*** was stratified according to the Hinchey classification. Patients were divided into 2 populations:group A≤ 50 years(n=31) ;group B>50 years(n=126) .Mean patient follow-up was 15 mo. rESULTS:The median age was 60 years.A significantly higher proportion of patients in group B presented with complicated diverticulitis(36.5%vs 12.9%,P=0.01) .recurrence was more frequent in group A(25.8%vs 11.1%,P=0.03) and the mean time-torecurrence was shorter(12 mo vs 28 mo,P=0.26) . The most severe recurrent episodes of acute diverticulitis were classified as Hinchey stageⅠand none of the patients required emergency *** multivariate analysis,only age(P=0.024) was identified as an independent prognostic factor for recurrence. CONCLUSION:Based on the results of this study,we recommend that diverticulitis management should be based on the severity of the disease and not on the age of the patient.

AIM:To analyze the costs of cancer drugs administered in a Portuguese Hospital compared with the Karolinska Institute ***:To evaluate spending on cancer drugs, we retrospectively analyzed data on the overall costs of cancer drugs, obtained at the Department of Medical Oncology of the Centro Hospitalar de Entre Douro e Vouga, between 2004 and 2010. In this comparative study we selected only drugs belonging to the following groups:chemotherapy, targeted therapy, immunotherapy and endocrine therapy. The selected drugs were further grouped according to their market placement year:≤ 1998, 1999 to 2002, 2003 to 2005, and 2006 to 2010. Drugs used as supportive therapy and bisphosphonates were ***:The overall costs of cancer drugs increased gradually between 2004 and 2008(from €1911947 to €3666284), with an increase in the number of patients treated during this period. The expenditure decreased in 2009(€3438155) and increased again in 2010(€3673116), but the costs increment was not the same as in previous years. Chemotherapy and targeted therapy were responsible for most of the expenditure. Drugs placed on the national market before 1999 accounted for more than 50% of the expenditure up to 2007. From 2008, these drugs represented less than 50% of the total expenditure. Cancer drugs placed between 1999 and 2002 accounted for 25%-35% of the costs in all the years studied, while drugs placed between 2003 and 2005 accounted for less than 30%. Drugs placed between 2006 and 2010 were responsible for less than 10% of the ***:In this study, older drugs were responsible for most of the expenditure up to 2007, which is in agreement with the Karolinska study.

Objective: To evaluate the antioxidant activity of the essential oil obtained from rosmarinus officinalis(r. officinalis) in ethanol-induced gastric ulcer model in ***: The antioxidant properties of the essential oil obtained from r. officinalis were evaluated against gastric injury induced by absolute ethanol. Gastric tissues were prepared to enzymatic assays. The levels of glutathione, lipid peroxides, and the activities of glutathione peroxidase, superoxide dismutase and myeloperoxidase were ***: Ethanol produced severe hemorrhagic lesions in the stomach with ulcerative lesion of(140.2 ± 37.2) mm2. In animals pretreated with essential oil of r. officinalis(50 mg/kg, p.o.), a significant inhibition of mucosal injury of(21.2 ± 7.1) mm2(84%inhibition) was observed. The essential oil of r. officinalis protected the gastric mucosa probably by modulating the activities of the enzymes(superoxide dismutase and glutathione peroxidase) and increasing or maintaining the levels of glutathione. In addition,lipid peroxides levels were reduced. The essential oil of r. officinalis was analyzed by gas chromatography–mass spectrometer and the main constituents were cineole(28.5%),camphor(27.7%) and alpha-pinene(21.3%).Conclusions: We suggest that the monoterpenes present in the essential oil obtained from r. officinalis may be among the active principles responsible for the antioxidant activity shown by essential oil of r. officinalis.
