Retrospective analysis of 155 liver angiographies and the literature data was carried out to appraise the current relevance of liver angiography in digital subtraction technique (i.a. DSA) for diagnosis of focal liver changes. A focal liver lesion was detected by angiography in 58 out of the 80 patients (72.5%) we investigated with a confirmed hepatic space occupation; an angiography correlate of the tumour type diagnosed was shown in 41 out of 69 (59.4%) of malignancies confirmed by surgery or biopsy histology; in the benign lesions, the angiographic diagnosis was consistent with the histological result in five out of six cases. DSA is thus usually clearly inferior to the tomographic sonography, CT and MRI in detection and qualification of the tumour type. However, it is still indispensable for planning operations or chemoembolization and for exact imaging of the portal perfusion conditions because of the frequent vascular anomalies in the anatomy of the liver.

Despite being designated as "noncarcinogenic" human papillomavirus (HPV) types, mono-infection with HPV6 or HPV11 has been found in squamous cell carcinomas (SCCs) at specific sites, including the larynx, penis, anus, and rarely, the lower female genital tract. The association between clinicopathologic features, viral status, and the carcinogenic mechanisms related to these low-risk HPVs remains unclear. The current study characterizes a series of low-risk HPV6 and HPV11-associated SCCs of the uterine cervix (6 cases) and vulva (2 cases).

Background: To investigate the incidence and potential predictors of immune tolerance among adult living donor liver transplant (LDLT) recipients.
Methods: This case-control study included adult recipients who underwent LDLT between May 2004 and January 2018, with at least a 5-year follow-up after LDLT. We divided the study recipients into two groups: Group 1 (Tolerance Group) included recipients who achieved operational or prope tolerance for at least one year; Group 2 (Control Group) included recipients who did not achieve tolerance.

Background: Pregnancy-associated atypical hemolytic uremic syndrome (aHUS) is a form of thrombotic microangiopathy (TMA) caused by uncontrolled activation of the complement system during pregnancy or the postpartum period. In the intensive care unit, aHUS must be differentiated from sepsis-related multiple organ dysfunction, thrombotic thrombocytopenic purpura (TTP), hemolysis, elevated liver enzymes, and low platelet (HELLP) syndrome. Early recognition of aHUS is critical for effective treatment and improved prognosis.

Pirfenidone (PIR) is used in the treatment of idiopathic pulmonary fibrosis. After oral administration, it is metabolized by cytochrome P450 1A2 to 5-hydroxylpirfenidone (5-OH PIR) and further oxidized to 5-carboxylpirfenidone (5-COOH PIR), a major metabolite excreted in the urine (90% of the dose). This study aimed to identify enzymes that catalyze the formation of 5-COOH PIR from 5-OH PIR in the human liver.

Hepatobiliary (HB) contrast agents are increasingly valuable diagnostic tools in MRI, offering a wider range of applications as their clinical use expands. Normal hepatocytes take up HB contrast agents, which are subsequently excreted in bile. This property creates a distinct HB phase providing valuable insights into liver function and biliary anatomy.
