Background and Objectives: Acute low tone sensorineural hearing loss (ALHL), an acuteonset hearing loss limited to low tone, was thought to be a subtype of sudden sensorineural hearing loss (SSNHL) but also considered as new disease entity because it shows quite different symptoms, progress, and prognosis. More recently, however, it is thought that SSNHL results from chronic inflammation and thrombosis. Some studies have reported that neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were high in SSNHL patients, and that they were significant as prognostic factors. The aim of this study was to evaluate the significance of NLR and PLR in ALHL.Subjects and Method From January 2009 to June 2019, we retrospectively studied 58 patients who were diagnosed with ALHL. Characteristics of patients such as sex, age, symptoms and signs, the results of serologic test and pure tone audiometry were evaluated for recovery and for recurrence. Also, we selected 58 people with the same age as control group. Results: A total of 167 patients were identified, of whom a half was diagnosed with ALHL and the other half with were the control group. Among the 58 patients, the mean age was 38.0±14.5 years old, and 10 (17.2%) patients were male and 48 (82.8%) patients were female. Among the patients, 35 (60.3%) were hospitalized and 23 (39.7%) were outpatients. For recovery, 38 (65.5%) patients fully recovered while 11 (19.0%) partially recovered, and 9 (15.5%) did not recover. Additionally, 16 (27.6%) patients recurred later with similar symptoms. Between the patient group and control group, there were significant differences in the total white blood cell count, neutrophil count, NLR and PLR (p=0.015, 0.001, 0.002, and 0.025), but there was no significant differences between the recovery group and non-recovery group in any laboratory findings. Also, NLR and PLR showed no significant differences between the recurred group and non-recurred group. Conclusion NLR and PLR in ALHL patients were relatively high compared to the control group, but there were no significant differences between the recovery group and non-recovery group. Furthermore, there was no correlation between NLR and PLR with recurrence. High NLR and PLR values in ALHL patients might reflect its inflammatory etiology, but there is lack evidence for them to serve as prognostic factors.

Biliary complications after orthotopic liver transplants are a continuing cause of morbidity and mortality. Biliary stones and sludge are less well known complications of hepatic transplantation, although they have long been recognized. Recently we experienced two cases of biliary stones developed after liver transplantation. One 32-year-old male, who frequently admitted due to recurrent cholangitis, was treated with percutaneous transhepatic biliary drainage and choledochojejunostomy with cholecystectomy. The other 58-year-old male, who had stones in commone bile duct, was treated by endoscopic manipulation. They are in good condition without recurrent bile duct stones or its accompanying complications. Although stones and sludge are relatively infrequent after liver transplantation, surgical or interventional radiologic treatments are usually performed for treatment.

The incidence and clinical significance of GB virus C/hepatitis G virus(GBV-C/HGV) infection were evaluated in 68 patients on maintenance hemodialysis. GBV-C/HGV RNA was identified in serum by a reverse transcription-polymerase chain reaction assay with nested primers deduced from a nonstructural region. Hepatitis B surface antigen(by RIA) and anti-hepatitis C(by ELISA) were checked simultaneously. Out of 68 patients, GBV-C/HGV RNA was detected in 5(7.4%), HBsAg in 4 patients(5.9%) and anti-HCV in 15 patients(22%). All 5 patients with positive GBV-C/HGV RNA had a history of blood transfusion. Out of 5 patients with positive GBV-C/HGV RNA, 2 patients were coinfected with hepatitis C virus, who showed chronic hepatitis clinically. Three patients with isolated GBV-C/HGV infection showed normal liver function during last 18 months' period. Between the patients with positive GBV-C/HGV RNA and those with negative GBV- C/HGV RNA, there was no difference in age, sex, duration of hemodialysis and amount of transfusion. Our data suggest that GBV-C/HGV infection may be present, with or without hepatitis C virus infection, in maintenance hemodialysis patients. Although the liver function of patients with isolated GBV-C/ HGV infection was normal, the clinical significance of this new virus remains to be determined.

Eosinophilic abscess is a rare disease of stomach that consists of many eosinophils in submucosa and muscle layers of stomach. Eosinophilic abscess is usually observed in liver after parasite infestation such as hepatic fascioliasis or in intradermal lesion of pemphigus. A 67-year-old female was admitted due to epigastric pain and indigestion. Endoscopic finding suggested early gastric cancer type IIc with the depth of invasion to mucosal layer at the lesser curvature of lower body. Histologic examination of endoscopic biopsy proved to be signet ring cell type adenocarcinoma. On endoscopic ultrasonography, the tumor was imaged as a slightly elevated mass with 15 mm in diameter. The lesion was localized from the first layer to the fourth layer which correspond to the mucosa and the proper muscle layer, The lesion consisted of low echoic and isoechoic densities. The lower echoic lesion ranging from the third layer to the fourth layer was thought to be necrotic or hemorrhagic portion within the tumor. Subtotal gasterectomy was performed. We compared the endoscopic and endosonographic features with the histologic findings of the resected stomach. Histologic examination showed signet ring cell carcinoma in mucosal layer and eosinophilic abscess in submucosal and proper muscle layer. We concluded that the endosonographic depth of invasion was overestimated because of the eosinophilic abscess.

To evaluate the clinical feasibility of the antibody titer against a chimeric polypeptide (named Core 518), in which a domain of Core and NS3 of hepatitis C virus (HCV) was fused, ELISA was performed in a total of 76 serum samples. Each serum was serially diluted using two-fold dilution method with distilled water into 10 concentrations. They were all positive for second generation anti-HCV assay (HCV EIA II; Abbott Laboratories). Genotyping RT-PCR, quantitative competitive RT-PCR, and RIBA (Lucky Confirm; LG Biotech) were also assayed. Anti-Core 518 antibody was detected in x 12800 or higher dilutions of sera from 35 of 43 chronic hepatitis C (81.4%) and nine of 16 hepatocellular carcinoma sera (56.3%), one of four cirrhosis (25%), 0 of four acute hepatitis C, and one of nine healthy isolated anti-HCV-positive subjects (p=0.0000). The anti-Core 518 antibody titers were well correlated with the presence of HCV RNA in serum (p=0.002). The anti-Core 518 antibody titers decreased significantly in nine of ten responders to IFN-alpha treatment. Monitoring anti-Core 518 titers may be helpful not only for differentiating the status of HCV infection among patients with various type C viral liver diseases, but also for predicting responses to IFN-alpha treatment.

Telomerase is highly activated in human immortal cell lines and tumor tissues, whereas it is not activated in primary cell strains and many tumor-adjacent tissues. It is suggested that telomerase activation is one of the critical steps in malignant transformation. In the present study, the telomerase activity was investigated in hepatocellular carcinoma tissues and non-tumor liver tissues from Korean patients with chronic hepatitis and cirrhosis. Eighty two liver tissues (24 chronic hepatitis specimens, 34 cirrhosis specimens, and 24 hepatocellular carcinomas) were obtained from 23 chronic viral hepatitis patients, 19 cirrhosis patients (including 7 liver transplants), and 24 patients with hepatocellular carcinoma, of which the surrounding non-tumor liver tissues were available in 16 patients (1 chronic hepatitis and 15 cirrhosis). As negative controls, 3 normal liver tissues were included. Protein from liver specimens was purified by a detergent lysis method as described elsewhere, and telomerase activity was measured in 2 diluents of each sample (1:1 and 1:100) by a telomeric repeat amplification protocol (TRAP). Telomerase was strongly activated in 79% (19/24) of the hepatocellular carcinomas, while weakly in 8% (2/24) of the chronic hepatitis tissues and in 24% (8/34) of the cirrhosis tissues. All of 3 normal control livers showed no telomerase activation. No relationship could be observed between the enhancement of telomerase activity and tumor nature. None of the chronic heaptitis or cirrhosis patients with mild telomerase activation in the liver have developed hepatocellular carcinoma for at least 2 years of follow-up period. These results suggest that the strong enhancement of telomerase activity may be a critical part of hepatocarcinogenesis, although the exact mechanism of such high activation in hepatocellular carcinoma is not clear. In addition, further study will be necessary to clarify the reason why no telomerase activity detectable by a conventional TRAP can be seen in some hepatocellular carcinoma.

A 79-year-old man was admitted to Samsung Changwon Hospital due to chest pain and dyspnea. The ejection fraction was 31% and mean pressure gradient between the left ventricle and aorta was 69.4 mmHg on echocardiography. Chest computed tomography showed severe calcification of the ascending aorta. Aortic valve replacement was successfully performed using a thoracic endovascular aortic repair balloon catheter without classic aortic cross clamping. The patient was discharged on the eleventh postoperative day.

Primary dissection of the renal artery is rare. Spontaneous renal artery dissection can be associated with diseases such as medial degeneration, neurofibromatosis, syphilitic arteritis, tuberculosis, polyarteritis nodosa, Marfan syndrome, fibromuscular dysplasia, or Ehlers-Danlos syndrome (EDS). Among these causes, EDS related renal artery dissection is very rare worldwide and has not been previously reported in Korea. EDS are a group of heritable connective tissue disorders characterized by fragility of the skin and hypermobility of the joints. We describe the case history of a young man who presented with left side flank pain, hypermobility of the hand joints and showed left renal artery dissection on computed tomography and angiography that turned out to be the first complication of vascular type EDS.

Green nail syndrome is characterized by greenish discoloration of the nail. It is caused by Pseudomas aeruginosa which is an aerobic gram-negative rod found in moist environment. The most common predisposing factors are frequent exposure to water and trauma history. Herein, we report two cases of green nail syndrome who developed greenish discoloration of finger nails, which were treated by systemic levofloxacin and gentian violet application.
