Cephalotaxus is the only genus of Cephalotaxaceae family, and its natural resources are declining due to habitat fragmentation, excessive exploitation and destruction. In many areas of China, folk herbal doctors traditionally use Cephalotaxus plants to treat innominate swollen poison, many of which are cancer. Not only among Han people, but also among minority ethnic groups, Cephalotaxus is used to treat various diseases, e. Read More

The aim of this work was to compare the prevalence of opisthorchiasis, diphyllobothriasis, and ascariasis among the rural indigenous and long-term resident people of Khanty-Mansi Autonomous Okrug (KMAO) in the years 1988-89 and 2018-19. Helminth infections were identified by faecal microscopic examinations conducted during health check-ups. We analysed 399 medical records for years 1988-89 and 549 records for 2018-19. Read More

Human ascariasis is the most common and prevalent neglected tropical disease and is estimated that ~819 million people are infected around the globe, accounting for 0.861 million years of disability-adjusted life years in 2017. Even with the existence of highly effective drugs, the constant presence of infective parasite eggs in the environment contribute to a high reinfection rate after treatment. Read More

Acute cholangitis is a condition of bacterial infection following hepatobiliary tract obstruction, which signifies poor prognosis unless adequately drained. The most common cause of bile duct obstruction is choledocholithiasis, in contrast to parasitic infestation, a rare entity causing acute cholangitis nowadays. Therefore, we reported the case of a 68-year-old Thai man who presented with acute fever, intense right upper quadrant abdominal pain and jaundice for 2 days. Read More

Parasites in the liver cause significant global morbidity and mortality, as they can lead to recurrent cholangitis, cirrhosis, liver failure and cancer. Due to climate change and globalisation, their incidence is increasing, especially in Europe. The correct diagnosis of a hepatic parasite is often delayed because clinicians are unfamiliar with respective entities. Read More

Ascariasis, which is caused by is the most common gastrointestinal parasitic infection worldwide, with occasional invasion of the biliary tract leading to a variety of complications. In rare cases, pathogens carried on the surface of can complicate the course of the disease and lead to superimposed bacterial infections. In this article, we present a case of ascariasis-induced cholangitis complicated with bacteremia and multiple hepatic microabscesses. Read More

Helminth infections such as ascariasis elicit a type 2 immune response resembling that involved in allergic inflammation, but differing to allergy, they are also accompanied with strong immunomodulation. This has stimulated an increasing number of investigations, not only to better understand the mechanisms of allergy and helminth immunity but to find parasite-derived anti-inflammatory products that could improve the current treatments of chronic non-communicable inflammatory diseases such as asthma. A great number of helminth-derived immunomodulators have been discovered and some of them extensively analysed, showing their potential use as anti-inflammatory drugs in clinical settings. Read More

The images presented here demonstrated how we arrived at the diagnosis of infection in a 54-year-old man with chronic abdominal pain by capsule endoscopy (CE). In this case, computed tomography (CT) images were not representative, and further investigation with CE was required to confirm the diagnosis. The combination of CT and CE was useful for diagnosing Ascaris lumbricoides infection in this patient. Read More
