About 80% of all pancreatic ductal adenocarcinoma patients suffer from a wasting syndrome referred to as the "cancer anorexia-cachexia syndrome" (CACS) characterized by abnormally low weight, weakness and loss of skeletal muscle mass with or without loss of body fat, which directly impacts overall survival, quality of life, and physical activity. The aim of this review was to examine recent findings about CACS' pathophysiology and to describe the current pharmacological approaches. In recent years many efforts were made to improve our knowledge of CACS; currently we know that cachexia arises from a complex and multifactorial interaction between various mechanisms including inflammation, anorexia/malnutrition, alterations of protein and lipid metabolism; consequently its management requires multidisciplinary and multipharmacological approach that should address the different causes underlying this clinical event. On these premises, several drugs have been proposed starting from the first pharmacological treatment based on progestational agents or corticosteroids; most of them are in the preclinical phase, but some have already reached the clinical experimentation stage. In conclusion, to date, there is no standard effective treatment and further studies are needed to unravel the basic mechanisms underlying CACS and to develop newer therapeutic strategies with the hope to improve the quality of life of pancreatic cancer patients., (Copyright © 2014 Medical University of Bialystok.

Background: Septic arthritis (SA) of the sternoclavicular joint (SCJ) is an uncommon form of arthritis, generally described in patients with predisposing risk factors such as primary or secondary immunosuppressive disorders, systemic or localized infections and central venous catheters. More rarely the infection occurs in patients without these risk factors, thus rendering difficult an early diagnosis., Material and Methods: We report two cases of SA of the SCJ occurred in two patient, without known predisposing risk factors, hospitalized in our Internal Medicine Unit., Results: The clinical characteristics didn't significantly differ from clinical course of the disease occurring in patients with predisposing risk factors. Imaging techniques were useful to suspect diagnosis, but only fine-needle aspiration biopsy with culture of specimens leaded to identify the pathogen and its antibiotic sensitivity (in both patients Staphylococcus aureus). One patient was treated with surgical adequate curettage, drainage and intravenous methicillin, while the other one received only medical treatment with intravenous teicoplanin and ceftazidime. The outcome was uneventful with a complete recovery in both cases., Conclusions: Even if SA of SCJ is uncommon in subjects without predisposing risk factors, the clinician must have a high index of suspicion to consider this disease in differential diagnosis of arthritis also in previously healthy subjects with negative or unsettling instrumental investigations. In fact, prompt diagnosis is essential to obtain a successful outcome, avoiding the prolongation of the hospitalization and the sequelae of a chronic infection.
