Laparoscopy assisted transjejunal endoscopic retrograde cholangiography for treatment of intrahepatic duct stones in a post Roux-en-Y patient

We report a case of a 17-year-old female patient, who was operated on for choledocal cyst with Roux-en Y hepatojejunostomy. She was admitted to hospital with recurrent attacks of acute ascending cholangitis due to left intrahepatic duct stones. After a failed attempt at conventional endoscopic retrograde cholangiopancreatography through the anatomical route, she was treated successfully with laparoscopy assisted transjejunal endoscopic retrograde cholangiography.Endoscopic access to the biliary system can be difficult in patients with surgically altered anatomy of the upper gastrointestinal tract (GIT), such as Roux-en-Y reconstruction, because of the changed anatomy. However, endoscopic retrograde cholangiopancreatography (ERCP) is challenging in cases such as our patient;1,2 this is due to the distance needed to be traversed and looping. Our objective in presenting this particular case is to describe and highlight a laparoscopy assisted transjejunal ERCP to permit successful treatment and removal of intrahepatic duct stones in a post Roux-en-Y patient, and to minimize surgical inetervention to reduce unnecessary risks to the patient.     

Histologically Unstable Asymptomatic Carotid Plaques Have Altered Expression of Genes Involved in Chemokine Signalling Leading to Localised Plaque Inflammation and Rupture

BackgroundMany studies have evaluated histological and gene expression profiles in TIA/stroke patients after onset of symptoms, but there is limited understanding as to how these plaque related features interact before symptom onset. In particular, no studies have evaluated differential gene expression in histologically unstable (vs stable plaques) in neurologically asymptomatic patients.MethodsNine asymptomatic patients had their plaques scored blindly by two independent Histopathologists using the AHA plaque scoring system. RNA extracted from the plaques was hybridised onto a whole genome microarray. Analysis was performed using GenomeStudio (v1.0) and the DAVID bioinformatics resource (v6.7).ResultsThree plaques were histologically unstable (Grade 2/3), while six were stable (Grade 0/1). 346 differentially expressed genes (>1.3 fold, P < 0.05) were identified (293 down-regulated and 53 up-regulated) between stable and unstable plaques. Genes related to chemokine and protein signalling (pro-inflammatory/pro-apoptotic) were identified to have high enrichment scores (>1.3) and were significantly up-regulated in unstable (asymptomatic) plaques.ConclusionThe findings confirm the intuitively held belief that changes in chemokine and protein signalling may be associated with acute plaque disruption and precede the onset of symptoms. Once validated, these genes could therefore become targets for innovative medical treatments in the future or could help identify asymptomatic patients with histologically unstable plaques that would benefit from surgical intervention.     

Impact of Nursing Intervention on Improving HIV, Hepatitis Knowledge and Mental Health Among Homeless Young Adults

In a prospective two-group pilot study of a convenient sample of 156 young adults, we assessed improvement in HIV cognitive and transmission knowledge, hepatitis knowledge, and mental health at six-month follow-up. Multiple linear regression analysis revealed higher six-month scores in total HIV/AIDS knowledge, HIV/AIDS cognitive knowledge, HIV transmission knowledge and HBV and HCV knowledge at 6 months in the Hepatitis Health Promotion (HHP) group compared to the Art Messaging (AM) group. Moreover, homeless young participants who reported having significant others in their lives, and excellent or very good health did better than their counterparts. Youth who were attempting to get their lives together had higher scores for all types of knowledge except HBV. Hallucinogen users had significantly worse scores on all knowledge measures than non-users. Lastly, the HHP group revealed an improvement in psychological well-being compared to the AM group.
