Heggie","doi":"10.12968/GASN.2012.10.3.8","DOIUrl":"https://doi.org/10.12968/GASN.2012.10.3.8","url":null,"abstract":"Primary sclerosing cholangitis (PSC) is an uncommon, chronic, cholestatic liver disease caused by inflammation and fibrosis that can involve the entire biliary tree (Chapman, 2011). This progressive process destroys both intra and extra hepatic bile ducts, leading to biliary cirrhosis, portal hypertension and hepatic failure. The cause of PSC is unknown but it is closely associated with inflammatory bowel disease, particularly ulcerative colitis (UC), which occurs in approximately 70% of cases. Approximately 5–10% of patients with total UC will have co-existing PSC (Chapman, 2011). PSC is often difficult to diagnose due to the complexity of its symptoms (European Association for the Study of the Liver, 2009). These symptoms include fatigue, intermittent jaundice, weight loss, right upper quadrant abdominal pain and pruritus. Cholangitis, sporadic episodes of inflammation within the biliary tract, often bacterial in nature cause pain, shivers, fever and distress and require immediate antibiotic therapy. Occasionally, more invasive treatment is needed. The clinical course of PSC is variable and there is no curative treatment apart from liver transplant; medical treatment has proven unsuccessful. Folseraas et al (2011) indicated that no treatment has confirmed any delay in progression, but studies are often conflicting (Chapman, 2009; Lindor et al, 2009). Barnabas and Chapman (2012) debated the use of ursodeoxycholic acid for PSC confirming that its role remains unclear. They found that a high dose (28–30 mg/ kg/day) may be harmful, while a low-tomoderate dose may have a carcinogenic protective effect. As diagnostic techniques are advancing rapidly, PSC is being identified earlier (Molodecky et al, 2011). Research is ongoing to try to find a treatment, cure or genetic link for this often debilitating condition. Folseraas et al (2011) state that genome wide studies have consistently identified genetic susceptibility and environmental factors—the relation of these hopefully offer exciting opportunities for transferring knowledge and impending treatment options. UK genome-wide studies are ongoing and recruitment is continuing (UK PSC Genome Study, 2011). The unpredictability of the condition is daunting and the uncertainty of how it will effect day to day life and future plans can bring major concerns and anxiety. Many people living with PSC describe it as very challenging: the itch and pain in particular causing daily stress which can reduce quality of life (Ponsioen, 2011). A decompensated liver can bring about many hurdles. For some, the addition of other related autoimmune conditions and immunosuppression due to prescribed therapy can be immense. As with any condition, an active healthy lifestyle is required. Good nutrition is vital for patients with a liver condition, even more important with associated inflammatory bowel disease. Access to dietary expertize is often limited; however, dieticians Leaper and Hamlin (2012) and the British Liver Trust","PeriodicalId":76505,"journal":{"name":"Rontgenpraxis; Zeitschrift fur radiologische Technik","volume":"14 1","pages":"374-5"},"PeriodicalIF":0.0,"publicationDate":"2012-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78234685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Schubert","doi":"10.53347/rid-14471","DOIUrl":"https://doi.org/10.53347/rid-14471","url":null,"abstract":"Pancreas divisum represents a developmental failure of the ducts of the dorsal and ventral pancreas to fuse during the second month of gestation. It results in separate drainage of the ventrally situated head of the pancreas through the main ampulla of Vater, via the duct of Wirsung, and drainage of the body and tail by the duct of Santorini through the much smaller accessory ampulla. It is a surprisingly frequent congenital abnormali ty present in 4.7-14% of necropsy series and has been demonstrated in 0.3-5.8% of patients undergoing endoscopic retrograde pancreatography (1). The etiologic relationship of pancreas divisum to pancreatitis is unresolved. Cotton and Kizu (2), in 1977, first described an increased incidence of pancreatitis in patients with pancreas divisum. While some investigators have supported pancreas divisum as a cause of acute recurrent pancreatitis (3-5), others have not been able to document such an association (6-8), and there is little evidence to support it as a cause of chronic pancreatitis (9). However , we have recently encountered a patient in whom the clinical course and radiologic and histopathologic findings supported an etiologic relationship between pancreas divisum and chronic pancreatitis.","PeriodicalId":76505,"journal":{"name":"Rontgenpraxis; Zeitschrift fur radiologische Technik","volume":"24 1","pages":"215-6"},"PeriodicalIF":0.0,"publicationDate":"2011-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79758327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
