Hepatic endometriosis is a very rare medical condition characterized by the implantation of ectopic endometrial tissue within the hepatic parenchyma. Preoperative diagnosis is difficult via cross-sectional imaging and histopathologic evaluation remains the gold standard for diagnosis. We report a case of hepatic endometrioma in a 44-year-old woman with history of endometriosis. The literature is reviewed, and magnetic resonance imaging findings together with differential diagnosis of hepatic endometriosis are highlighted...

Perivascular epithelioid cell tumor (PEComa) is a rare, soft tissue tumor that can occur in various locations. The present report included three patients (one male and two females; age range, 25-51 years) with hepatic PEComas. The collected data included the clinical manifestations, diagnosis, management, treatment, and prognosis. Since it is difficult to diagnose hepatic PEComas by imaging, the patients were diagnosed by tumor tissue examination such as immunohistochemistry, which was positive for HMB-45, Melan-A, and SMA on all slides...

#3
Meng-Lan Wang, Hong Tang
BACKGROUND: The long-term use of nucleos(t)ide analogues causes drug resistance and mutations in the HBV reverse transcriptase (RT) region of the polymerase gene. The RT region overlaps the HBV surface gene (S gene) and therefore, the mutations in the RT region simultaneously modify S gene sequence. Certain mutations in the RT region bring about truncated S proteins because the corresponding changed S gene encodes a stop codon which results in the loss of a large portion of the C-terminal hydrophobic region of HBV surface protein...

REVIEW
Safak Kiziltas
Toll-like receptors (TLRs) are pattern recognition receptors that participate in host defense by recognizing pathogen-associated molecular patterns alongside inflammatory processes by recognizing damage associated molecular patterns. Given constant exposure to pathogens from gut, strict control of TLR-associated signaling pathways is essential in the liver, which otherwise may lead to inappropriate production of pro-inflammatory cytokines and interferons and may generate a predisposition to several autoimmune and chronic inflammatory diseases...

Recent advances in the treatment of alcoholic hepatitis (AH) have reinforced the utility of glucocorticoids, a treatment that has been in use for nearly 4 decades, to enhance short-term survival. As multi-institutional consortia research new therapeutic advances, this orphan disease, which afflicts younger patients and has poor outcomes, continues to be difficult to manage. AH has a protean clinical presentation and course, with various prediction models and treatment approaches that can challenge even experienced providers...

Urs Christen, Edith Hintermann
Autoimmune hepatitis (AIH) is characterized by a progressive destruction of the liver parenchyma and a chronic fibrosis. The current treatment of autoimmune hepatitis is still largely dependent on the administration of corticosteroids and cytostatic drugs. For a long time the development of novel therapeutic strategies has been hampered by a lack of understanding the basic immunopathogenic mechanisms of AIH and the absence of valid animal models. However, in the past decade, knowledge from clinical observations in AIH patients and the development of innovative animal models have led to a situation where critical factors driving the disease have been identified and alternative treatments are being evaluated...

Dehydropyrrolizidine alkaloid (DHPA)-producing plants have a worldwide distribution amongst flowering plants and commonly cause poisoning of livestock, wildlife, and humans. Previous work has produced considerable understanding of DHPA metabolism, toxicity, species susceptibility, conditions, and routes of exposure, and pathogenesis of acute poisoning. Intoxication is generally caused by contaminated grains, feed, flour, and breads that result in acute, high-dose, short-duration poisoning. Acute poisoning produces hepatic necrosis that is usually confirmed histologically, epidemiologically, and chemically...

MicroRNAs (miRNAs), a large family of small and highly conserved non-coding RNAs, regulate gene expression through translational repression or mRNA degradation. Aberrant expression of miRNAs underlies a spectrum of diseases including organ fibrosis. Recent evidence suggests that miRNAs contribute to organ fibrosis through mediating epithelial-mesenchymal transition (EMT). Alleviation of EMT has been proposed as a promising strategy against fibrotic diseases given the key role of EMT in fibrosis. miRNAs impact the expression of specific ligands, receptors, and signaling pathways, thus modulating EMT and consequently influencing fibrosis...

The Patient Protection and Affordable Care Act established health insurance marketplaces to allow consumers to make educated decisions about their health care coverage. During the first open enrollment period in 2013, the federally facilitated marketplace in Pima County, Arizona listed 119 plans, making it one of the most competitive markets in the country. This study compares these plans based on differences in consumer cost sharing, including deductibles, co-pays and premiums. Consumer costs were reviewed using specific cases including a normal delivery pregnancy, the management of Type II Diabetes, and the utilization of specialty drugs to treat Hepatitis C...

BACKGROUND: We examined discharges for infective endocarditis (IE) at an academic teaching hospital for over 10 years to evaluate if an increase in hospitalizations for IE and increase in hepatitis C virus (HCV) in patients with IE could predict a new epidemic of injection drug use (IDU). MATERIALS AND METHODS: Retrospective medical record review of discharged patients with the diagnosis of IE as defined by the modified Duke criteria. Student's t test, chi-squared test and Fisher's exact test were used to calculate P values...

INTRODUCTION: Para-aortic lymph node (PALN) involvement occurs in up to 2% of colorectal cancer (CRC) patients. While resection for isolated hepatic and pulmonary metastases in colorectal cancer is standard practice, the role of PALN dissection (PALND) in CRC has not been established and remains a controversy. We aim to perform a systematic review of the literature to determine if extensive lymphadenectomy improves survival, and is an acceptable strategy for PALN metastasis (PALNM). MATERIALS AND METHODS: A systematic search of PubMed and Embase databases for studies reporting on patients with isolated PALNM in CRC was performed...

AIMS: To investigate the underlying neurobiology between alcohol use, misuse and dependence and cognitive impairment, particularly Alzheimer's disease (AD). METHODS: Review of the literature using searches of Medline, Pubmed, EMBASE, PsycInfo, and meeting abstracts and presentations. RESULTS: The role of alcohol as a risk factor and contributor for cognitive decline associated with AD has received little attention. This is despite the high prevalence of alcohol use, the potential reversibility of a degree of cognitive impairment and the global burden of AD...

We report a case of polymorphous hemangioendothelioma, a rare vascular neoplasm, arising in the liver of a 51-year-old woman. Microscopically, this neoplasm is characterized by a polymorphous blend of solid, primitive vascular and angiomatous areas in variable proportions. Polymorphous hemangioendothelioma is considered to be an intermediate-grade vascular neoplasm. In most of the reported cases, its occurrence has been in lymph nodes, but a few cases have been found in extranodal sites such as the mediastinum, spinal cord, and liver...

Hepatitis E virus (HEV) infections are not limited to the liver but may also affect other organs. Several diseases, including Guillain-Barré syndrome, neuralgic amyotrophy, glomerulonephritis, cryoglobulinemia, pancreatitis, lymphoma, thrombopenia, meningitis, thyreoiditis and myocarditis have been observed in the context of hepatitis E. To date the definite pathophysiological links between HEV and extrahepatic manifestations are not yet established. However, it is suggested that HEV-infection might be causative based on serological studies, case series, in vitro data and animal models...

Aneurysms of pancreatic arteries (PAs) are often found incidentally during evaluation of other abdominal pathology. Aneurysms involving multiple PAs are rarely reported in the literature. In case reports of PA aneurysm, inferior pancreaticoduodenal artery is the usual site of aneurysm occurrence. PA aneurysms can be treated surgically by aneurysm exclusion, excision, and by endovascular techniques. However, no clear consensus exists regarding treatment modality, leaving the surgeon to determine the most appropriate approach bearing in mind their experience, anatomical location of the aneurysm, involved artery and urgency of the procedure...

The incidence of hepatocellular carcinoma (HCC) in patients with thalassemia is on the rise. The 2 well recognized HCC risk factors in thalassemia are iron overload and chronic viral infection with hepatitis C. The carcinogenicity of iron is related to its induction of oxidative damage, which results in genotoxicity, and to immunologic dysregulation, which attenuates cancer immune surveillance. Chronic hepatitis B and C infections lead to necroinflammation, which can prompt progression to HCC, but an independent role of hepatitis B virus in hepatic carcinogenesis among patients with thalassemia has not been demonstrated...
