Epstein-Barr virus-induced infection-associated hemophagocytic lymphohistiocytosis with acute liver injury: A case report.

BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) is a severe hyperinflammatory reaction, which is rare and life-threatening. According to the pathogen, HLH is divided into genetic and acquired. The most common form of acquired HLH is infection-associated HLH, of which Herpes viruses, particularly Epstein-Barr virus (EBV), are the leading infectious triggers. However, it is difficult to distinguish between simple infection with EBV and EBV-induced infection-associated HLH since both can destroy the whole-body system, particularly the liver, thereby increasing the difficulty of diagnosis and treatment. CASE SUMMARY: This paper elaborates a case about EBV-induced infection-associated HLH and acute liver injury, aiming to propose clinical guides for the early detection and treatment of patients with EBV-induced infection-associated HLH. The patient was categorized as acquired hemophagocytic syndrome in adults. After the ganciclovir antiviral treatment combined with meropenem antibacterial therapy and methylprednisolone inhibition to inflammatory response, gamma globulin enhanced immunotherapy, the patient recovered. CONCLUSION: From the diagnosis and treatment of this patient, attention should be paid to routine EBV detection and a further comprehensive understanding of the disease as well as early recognition and early initiation are keys to patients' survival.

International incidence trends in early- and late-onset colorectal cancer: a population-based study.

PURPOSE: Knowing the global incidence of colorectal cancer (CRC), by sex and age of onset, is of great importance for understanding the disease burden of CRC. METHODS: The CRC incidence data, by cancer site, age of onset, sex, country, and year, were retrieved from the Cancer Incidence in Five Continents Vol. Plus database. Estimated annual percentage changes (EAPC) were calculated to quantify the temporal trends in the CRC age-standardized incidence rate. RESULTS: Globally, the incidence of late-onset CRC was heterogeneous and remained increasing in most countries. The highest incidence of late-onset colon and rectal cancer was both found in males in Slovakia (156.5/100,000 and 121.5/100,000, respectively). The most pronounced increases were mostly observed in developing countries, such as Brazil (colon cancer: EAPC = 5.87, 95% CI 3.18, 8.63; rectal cancer: EAPC = 4.68; 95% CI 2.78, 6.62). The highest incidence of early-onset colon and rectal cancer was found in females in Switzerland (4.2/100,000) and in males in South Korea (4.6/100,000), respectively. The incidences of early-onset CRC were increased in parts of countries, including countries experiencing a decline in late-onset CRC incidence, such as the USA, Germany, and Australia. The temporal trends of colon cancer were mostly aligned with those of rectal in most countries, independent of sex and age of onset. CONCLUSION: The increase of early-onset CRC incidence suggests more prevention initiatives are urgently warranted for young adults in the near future. Targeted and effective prevention measures are still needed among elderly populations.

A new species of Isoperla (Plecoptera: Perlodidae) from the Qinling Mountains of northwestern China and notes on the Chinese species of the genus.

A new species of the perlodid genus Isoperla Banks, 1906, Isoperla qinlinga Chen, sp. nov. from Shaanxi Province of northwestern China is described. The new species is characterized by the mostly dark head and pronotum, the poorly developed vesicle, the modified ventral and dorsal aedeagal lobes, and the slightly developed, rounded subgenital plate of the female. Comments are provided on the known species of Isoperla of China.
