The association between deficiency of alpha-1-antitrypsin (A1AT) and glomerulonephritis has been only sporadically reported on, as opposed to the linkage between A1AT-deficiency and lung emphysema or hepatic cirrhosis. We describe the case of a 30-year-old man with A1AT deficiency who developed hepatic cirrhosis in early childhood, and IgA glomerulonephritis and hypertension in adult life. The IgA nephritis followed an unusual course. After three years of slight elevation of serum creatinine levels, the patient rapidly developed renal failure necessitating acute hemodialysis. The deterioration of the renal function was preceded by eruption of skin lesions, believed to represent a vasculitis. After six months of hemodialysis, the patient successfully received a transplanted kidney from his mother. The literature is reviewed with respect to the association between A1AT-deficiency and renal disease. We discuss possible underlying causes for the rapid deterioration of renal function in this patient.

Background: Robotic hepatectomy has been increasingly adopted for the treatment of hepatocellular carcinoma (HCC). However, the ideal technique of parenchymal transection in robotic hepatectomy has been a matter of ongoing debate in literature.
Patients And Methods: In this video, we demonstrate the technique of robotic anatomical segment VIII resection using the scissor hepatectomy technique for parenchymal transection on a 75-year-old male patient with a solitary HCC lesion.

Background Photoacoustic microscopy (PAM) can be used to detect strong absorption from endogenous and exogenous contrast material, making it promising for detailed structural and functional imaging of hepatic sinusoids, including dynamic visualization of permeability. Purpose To evaluate whether PAM-based quantitative parameters of liver function and integrity (lacunarity, blood oxygen saturation [Sao], and Evans blue [EB] permeability) are associated with histopathologic indexes of fibrosis in a mouse model. Materials and Methods Between October 2022 and July 2023, a total of 35 male C57BL/6 mice were included in this study and received intraperitoneal injection of carbon tetrachloride to establish mouse models of progressive liver fibrosis, with seven mice in each group.

Hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) are two distinct pulmonary vascular complications seen in patients with liver disease and/or portal hypertension. HPS is characterized by disturbed gas exchange and hypoxemia because of intrapulmonary vascular dilatations. POPH is defined by pulmonary arterial hypertension, which might lead to right heart failure.

Background/Aims: To evaluate invasive treatment outcomes for hepatocellular carcinoma (HCC) in patients aged over 90 years. Materials and methods: Twenty-six patients were included. Information on backgrounds, course of treatment, outcomes, and changes in Child-Pugh (CP) score and performance status (PS), as well as a comparison of treatment-related complications and 2-year survival after treatment, were retrospectively examined and compared with 311 patients aged under 90 years who were matched under the same conditions.
