Abdominal Actinomycosis Abscess Mimicking Malignancy: A Case Report and Review of the Literature.

Actinomycosis is a rare chronic granulomatous infection caused by species. We report the case of a 47-year-old man with no previous medical history, who presented with a slowly growing abdominal mass extending to the abdominal wall, initially mimicking a malignant tumor. A diagnosis of an abscess was confirmed through surgical resection and histopathological examination.

Epidemiology of bone tumors in children and adolescents: a retrospective study of 266 patients in the south of Tunisia.

Although bone tumors (BT) are relatively uncommon among the human neoplasm, they constitute the most frequent tumors in children and adolescents (CAA). Little information is available about the epidemiologic features of BT in CAA. We aimed to present and discuss epidemiological characteristics of BT in CAA in southern Tunisia, regarding the different histological types.

Anti-Vasculogenic, Antioxidant, and Anti-Inflammatory Activities of Sulfated Polysaccharide Derived from : Pharmacokinetic Assay.

The purpose of this paper was to investigate the anti-inflammatory and anti-angiogenic activities of sulfated polysaccharide from (PCT) using carrageenan (CARR)-induced paw edema in a rat model and anti-vasculogenic activity on a chorioallantoic membrane assay (CAM) model. Based on in vitro tests of anti-radical, total antioxidant, and reducing power activities, PCT presents a real interest via its antioxidant activity and ability to scavenge radical species. The in vivo pharmacological tests suggest that PCT possesses anti-inflammatory action by reducing paw edema and leukocyte migration, maintaining the redox equilibrium, and stabilizing the cellular level of several pro-/antioxidant system markers.

Pleomorphic carcinoma of the lung revealed by uncommon colonic metastasis: An exceptional case report with literature review.

Lung pleomorphic carcinoma is a rare and aggressive cancer that uncommonly metastasizes to the colon and only a few case reports have been published thus far. We present an exceptional case of colon metastasis from lung pleomorphic carcinoma in a 68-year-old man which was revealed by large bowel perforation, and we review the previous three published cases. Metastasis to the bowel from primary lung malignancy often lacks specific symptoms which result in delayed diagnosis.

Anti-Inflammatory and Immunomodulatory Properties of a Crude Polysaccharide Derived from Green Seaweed : Computational and Experimental Evidences.

In this study, we investigated for the first time the anti-inflammatory and immunomodulatory properties of crude polysaccharide (PSHT) extracted from green marine algae . PSHT exhibited anti-oxidant activity in vitro through scavenging 1, 1-diphenyl-2-picryl hydroxyl free radical, reducing Fe/ferricyanide complex, and inhibiting nitric oxide. PSHT maintained the erythrocyte membrane integrity and prevented hemolysis.
