“Playboy Bunny” Sign of Congestive Heart Failure

In emergency, ultrasound has been widely used as a noninvasive and effective examination to evaluate congestive heart failure. We highlight “Playboy Bunny” sign as a reliable marker and an important clue to the diagnosis of passive hepatic congestion, caused by congestive heart failure

Trends in hepatocellular carcinoma incident cases in Japan between 1996 and 2019

We examined the epidemiological trends, including the distribution of sex, age, and disease etiology, in HCC incident cases, over 24 years. Data of 20,547 HCC patients (1996–2019) were analyzed in this prospective study. We divided the study period into four 6-yearly quarters. HCC etiology was categorized as hepatitis B virus (HBV) infection, HBV + hepatitis C virus (HCV) infection, HCV infection, and both negative (non-BC). The incident cases of HCC per quarter of the study period were 4311 (21.0%), 5505 (26.8%), 5776 (28.1%), and 4955 (24.1%), sequentially. Overall, 14,020 (68.2%) patients were male. The number of HCC cases in patients < 60 years, 60–69 years, 70–79 years, and ≥ 80 years were 3711 (18.1%), 6652 (32.4%), 7448 (36.2%), and 2736 (13.3%), respectively. The average age of newly-diagnosed patients increased in each quarter. HCC was associated with HBV, HBV + HCV, and HCV infections and non-BC in 2997 (14.6%), 187 (0.9%), and 12,019 (58.5%), and 5344 (26.0%) cases, respectively. The number of HCV-associated cases decreased in each quarter, while that of non-BC-associated cases increased. HCC incident cases tend to increase in the elderly and in non-BC patients; in contrast, HCC incident cases due to HCV tend to decrease

Successful Treatment of Oral Lichen Planus with Direct-Acting Antiviral Agents after Liver Transplantation for Hepatitis C Virus-Associated Hepatocellular Carcinoma

Hepatitis C virus (HCV) infection is frequently associated with various extrahepatic manifestations, such as autoimmune features and immune complex deposit diseases. Oral lichen planus (OLP) is one such extrahepatic manifestation of HCV infection. Recently, direct-acting antivirals (DAA) have proved to be highly effective and safe for the eradication of HCV. Herein, we report a case of OLP accompanied by HCV-related hepatocellular carcinoma (HCC) that disappeared after liver transplantation and achievement of sustained virological response following interferon (IFN)-free treatment with ledipasvir (LDV) and sofosbuvir (SOF). The 50-year-old patient developed erosive OLP during IFN therapy, with hyperthyroidism at 53 years of age and HCC at 55 years. He received immunosuppressive drugs and IFN-free DAA treatment after liver transplantation at 60 years of age, which led to disappearance of the symptoms of OLP. The patient was treated safely and effectively with LDV/SOF, although it is not known whether the disappearance of OLP resulted from the eradication of HCV or the immunosuppressive therapy

Tuberculous Lymphadenopathy Mimicking Pancreatic Neoplasm

Abdominal tuberculosis (TB) is the sixth most common location of extrapulmonary TB involvement. Because its symptoms and signs are often nonspecific, laboratory and imaging findings mimic other diseases including carcinoma. Therefore, the diagnosis of abdominal TB is challenging. We herein report a case of 74-year-old woman who presented with abdominal pain, anorexia, and weight loss. She had been given a diagnosis of pancreatic head carcinoma. Laboratory data was unremarkable except for elevated erythrocyte sedimentation rate, CA125, and sIL-2R. CT scan revealed multiple enlarged peripancreatic lymph nodes and concentric thickening of the ileocecal wall. Colonoscopy demonstrated deformed ileocecal valve and erosions. Histological examination showed epithelioid granulomas. Laparoscopy revealed numerous white tubercles diffusely covering the parietal peritoneum. Histopathological images of peripancreatic lymph node revealed large multiple caseating granulomas surrounded by Langhans_giant cells and epithelioid cells. Polymerase chain reaction and culture of the specimens were positive for Mycobacterium tuberculosis. Tuberculous lymphadenopathy, colitis, and peritonitis were finally diagnosed. She responded well to the antitubercular treatment

A Genetic Variant of Hepatitis B Virus Divergent from Known Human and Ape Genotypes Isolated from a Japanese Patient and Provisionally Assigned to New Genotype J▿ †

Hepatitis B virus (HBV) of a novel genotype (J) was recovered from an 88-year-old Japanese patient with hepatocellular carcinoma who had a history of residing in Borneo during the World War II. It was divergent from eight human (A to H) and four ape (chimpanzee, gorilla, gibbon, and orangutan) HBV genotypes, as well as from a recently proposed ninth human genotype I, by 9.9 to 16.5% of the entire genomic sequence and did not have evidence of recombination with any of the nine human genotypes and four nonhuman genotypes. Based on a comparison of the entire nucleotide sequence against 1,440 HBV isolates reported, HBV/J was nearest to the gibbon and orangutan genotypes (mean divergences of 10.9 and 10.7%, respectively). Based on a comparison of four open reading frames, HBV/J was closer to gibbon/orangutan genotypes than to human genotypes in the P and large S genes and closest to Australian aboriginal strains (HBV/C4) and orangutan-derived strains in the S gene, whereas it was closer to human than ape genotypes in the C gene. HBV/J shared a deletion of 33 nucleotides at the start of preS1 region with C4 and gibbon genotypes, had an S-gene sequence similar to that of C4, and expressed the ayw subtype. Efficient infection, replication, and antigen expression by HBV/J were experimentally established in two chimeric mice with the liver repopulated for human hepatocytes. The HBV DNA sequence recovered from infected mice was identical to that in the inoculum. Since HBV/J is positioned phylogenetically in between human and ape genotypes, it may help to trace the origin of HBV and merits further epidemiological surveys
