A systematic review of the present and future of non-alcoholic fatty liver disease.

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the Western world. Ongoing research has furthered our understanding of NAFLD, the nature of progression of this disease, and its impact on morbidity and mortality. An active form of NAFLD is non-alcoholic steatohepatitis (NASH); it is the most severe subtype, without any current recommended therapies, according to the European Medicines Agency.

An overview of Human Papillomavirus (HPV) as an etiological factor of the anal cancer.

Human papillomavirus (HPV) is a DNA tumour virus that is the primary cause of sexually transmitted infections (STIs). The direct connection between HPV and cervical cancer was discovered in 1980, however, many physicians and the general public are still oblivious to the association of HPV and anal cancer; most individuals find out about this relationship after a confirmed diagnosis, and therefore, it is important to raise awareness about HPV as an etiological agent in anal cancer. There is a quadrivalent vaccine available, which prevents an individual from being infected with HPV, thus anal cancer is mainly a preventable cancer when caused by HPV, and ultimately, preventing cancer is better than curing cancer, especially when there is no definite cure.

Hepatitis E - A new era in understanding.

Hepatitis E virus [HEV], the last of the five hepatotropic viruses to be discovered, was originally considered to cause an acute, travel-associated self-limiting illness restricted to humans; however, new research shows that there are animal reservoirs and zoonotic transmission. Additionally, HEV is now considered as a major health burden worldwide, leading to significant morbidity and mortality; therefore, the topic of hepatitis E is of re-emerging importance, having brought to light important questions such as the transmission of HEV, especially in developed countries, as well as treatment and vaccination options. HEV belongs to the genus Hepevirus in the family.

Acute hepatitis A virus infection in patients hospitalised at the Department of Infectious Diseases, Medical University of Lublin (Eastern Poland) in the years 2009-2015.

The aim of our study was to analyse all medical records from the years 2009-2015 for adult patients with acute hepatitis A virus (HAV) infection who were hospitalised at the Department of Infectious Diseases, Medical University of Lublin (Eastern Poland). During this 7-year study, there were only 5 hospitalised patients with confirmed HAV infection.
