Background: Liver cirrhosis has become a heavy burden not only for patients, but also for our society. However, little is known about the recent changes in clinical outcomes and characteristics of patients with cirrhosis-related complications in Korea. Therefore, we aimed to evaluate changes in characteristics of patients with liver cirrhosis in Daegu-Gyeongbuk province in Korea over the past 15 years. Methods: We retrospectively reviewed the medical records of 15,716 liver cirrhotic patients from 5 university hospitals in Daegu-Gyeongbuk province from 2000 to 2014. The Korean Standard Classification of Diseases-6 code associated with cirrhosis was investigated through medical records and classified according to the year of first visit. Results: A total of 15,716 patients was diagnosed with cirrhosis. A number of patients newly diagnosed with cirrhosis has decreased each year. In 2000, patients were most likely to be diagnosed with hepatitis B virus (HBV) cirrhosis, followed by alcoholic cirrhosis. There was a significant decrease in HBV (P < 0.001), but alcohol, hepatitis C virus (HCV), and non-alcoholic fatty liver disease (NAFLD) showed a significant increase during the study period (alcohol, P = 0.036; HCV, P = 0.001; NAFLD, P = 0.001). At the time of initial diagnosis, the ratio of Child-Turcotte-Pugh (CTP) class A gradually increased from 23.1% to 32.9% (P < 0.001). The most common cause of liver-related hospitalization in 2000 was hepatocellular carcinoma (HCC) (25.5%); in 2014, gastrointestinal bleeding with esophageal and gastric varices (21.4%) was the most common cause. Cases of hospitalization with liver-related complication represented 76.4% of all cases in 2000 but 70.9% in 2014. Incidence rate of HCC has recently increased. In addition, HCC-free survival was significantly lower in CTP class A than in classes B and C. Finally, there was significant difference in HCC occurrence according to causes (P < 0.001). HBV and HCV cirrhosis had lower HCC-free survival than alcoholic and NAFLD cirrhosis. Conclusion In recent years, the overall number of cirrhosis patients has decreased. This study confirmed the recent trend in decrease of cirrhosis, especially of cirrhosis due to HBV, and the increase of HCV, alcoholic and NAFLD cirrhosis. Targeted screening for at-risk patients will facilitate early detection of liver diseases allowing effective intervention and may have decreased the development of cirrhosis and its complications.

BACKGROUND/AIMS: Previous studies have reported a high rate of sustained virologic response (SVR) and a low rate of serious adverse events with the use of daclatasvir (DCV) and asunaprevir (ASV) combination therapy. We evaluated the efficacy and safety of DCV and ASV combination therapy for patients with chronic hepatitis C virus (HCV) genotype 1b infection in real world. METHODS: We enrolled 278 patients (184 treatment-naïve patients) from five hospitals in Daegu and Gyeongsangbuk-do. We evaluated the rates of rapid virologic response (RVR), end-of-treatment response (ETR), and SVR at 12 weeks after completion of treatment (SVR12). Furthermore, we investigated the rate of adverse events and predictive factors of SVR12 failure. RESULTS: The mean age of patients was 59.5 ± 10.6 years, and 140 patients (50.2%) were men. Seventy-seven patients had cirrhosis. Baseline information regarding nonstructural protein 5A (NS5A) sequences was available in 268 patients. Six patients presented with pretreatment NS5A resistance-associated variants. The RVR and the ETR rates were 96.6% (258/267) and 95.2% (223/232), respectively. The overall SVR12 rate was 91.6% (197/215). Adverse events occurred in 17 patients (7.9%). Six patients discontinued treatment because of liver enzyme elevation (n = 4) and severe nausea (n = 2). Among these, four achieved SVR12. Other adverse events observed were fatigue, headache, diarrhea, dizziness, loss of appetite, skin rash, and dyspnea. Univariate analysis did not show significant predictive factors of SVR12 failure. CONCLUSIONS DCV and ASV combination therapy showed high rates of RVR, ETR, and SVR12 in chronic HCV genotype 1b-infected patients in real world and was well tolerated without serious adverse events.

Patients with traumatic aortic rupture rarely reach the hospital alive. Even among those who arrive at the hospital alive, traumatic aortic rupture after high-speed motor vehicle accidents leads to a high in-hospital mortality rate and is associated with other major injuries. Here, we report a rare case of descending midthoracic aortic rupture with blunt diaphragmatic rupture. Successful management with emergency laparotomy after an immediate endovascular procedure resulted in a favorable prognosis in this case.

BACKGROUND: The benefits of video-assisted thoracoscopic surgery (VATS) have been demonstrated over the past decades; as a result, VATS has become the gold-standard treatment for primary spontaneous pneumothorax (PSP). Due to improvements in surgical technique and equipment, single-port VATS (s-VATS) is emerging as an alternative approach to conventional three-port VATS (t-VATS). The aim of this study was to evaluate s-VATS as a treatment for PSP by comparing operative outcomes and recurrence rates for s-VATS versus t-VATS. METHODS: Between March 2013 and December 2015, VATS for PSP was performed in 146 patients in Kyungpook National University Hospital. We retrospectively reviewed the medical records of these patients. RESULTS: The mean follow-up duration was 13.4±6.5 months in the s-VATS group and 28.7±3.9 months in the t-VATS group. Operative time (p<0.001), the number of staples used for the operation (p=0.001), duration of drainage (p=0.001), and duration of the postoperative stay (p<0.001) were significantly lower in the s-VATS group than in the t-VATS group. There was no difference in the overall recurrence-free survival rate between the s-VATS and t-VATS groups. CONCLUSION: No significant differences in operative outcomes and recurrence rates were found between s-VATS and t-VATS for PSP. Therefore, we cautiously suggest that s-VATS may be an appropriate alternative to t-VATS in the treatment of PSP.

Primary amyloidosis has unfavorable prognosis, particularly with organ involvement. Here, we report a case of clinical remission of renal amyloidosis after autologous hematopoietic cell transplantation. A 51-year-old female patient visited our hospital due to generalized edema. Initial evaluation showed hyperlipidemia, hypoalbuminemia, and heavy proteinuria, which were consistent with nephrotic syndrome. However, IgM lamda type monoclonal gammopathy was detected in serum and urine electrophoresis studies. Renal biopsy showed Congo red-positive amyloid deposition in mesangial area, glomerular capillary walls, and arterioles and amyloid fibers were confirmed by electron microscopy. Immunohistochemial study of the biopsy tissue demonstrated systemic light-chain amyloidosis (AL amyloidosis). Multiple myeloma was not evident on bone marrow examination. She received autologous hematopoietic cell transplantation after high dose melphalan treatment. Complete remissions were achieved after the treatment, respectively. Our findings suggest the potential role of autologous peripheral blood stem cell transplantation in treatment of AL amyloidosis.

BACKGROUND/AIMS: Pegylated interferon (peginterferon) and ribavirin combination therapy is less effective and associated with a higher frequency of serious complications in chronic hepatitis C patients with cirrhosis than in noncirrhotic patients. This study evaluated the efficacy and tolerability of peginterferon and ribavirin treatment in patients with hepatitis C virus (HCV)-related cirrhosis. METHODS: Eighty-six patients with clinically diagnosed liver cirrhosis were treated with either peginterferon alpha-2a (n=51) or peginterferon alpha-2b (n=35) plus ribavirin. The sustained virologic response (SVR) and adverse effects were analyzed retrospectively. RESULTS: Of the 86 patients (55 males), 48 patients (55.8%) had HCV genotype 1 infection and 38 (44.2%) had genotype non-1 infection. The overall SVR rate was 34.9% (30/86), and the rates of SVR in the genotype 1 and non-1 patients were 20.8% (10/48) and 52.6% (20/38), respectively. The multivariate analysis revealed that having HCV genotype 1 (P=0.003) and high baseline viral load (>8.0x10(5) IU/mL, P=0.012) were the independent predictive factors for SVR failure. In 20.9% (18/86) of the patients, treatment was not completed due to adverse events (27.8%), loss to follow-up (50.0%), and other reasons (22.2%). CONCLUSIONS: Peginterferon and ribavirin combination therapy was relatively effective and feasible for clinically diagnosed HCV patients, especially in those with genotype non-1 infection and low baseline viral load.

Acrodermatitis enteropathica is classified as a congenital autosomal recessive type and an acquired transient type. This disease manifests as acral and periorificial dermatitis, alopecia, intractable diarrhea, and failure to thrive. Whereas the autosomal hereditary type is caused by malabsorption of zinc in the intestine, the acquired type is caused by low nutritional support or decreased peripheral release of zinc from blood. We experienced a case of a 5-month old, breast feeding, full-term female presenting with only acral bullous dermatitis without diarrhea, periorificial dermatitis and an abnormal serum zinc level.

Various methods have been used to investigate the hair shaft. In the ultrastructural hair field, scanning and transmission electron microscopies are widely used investigative methods, but they have some technical limitations. Recently, X-ray microscopes with sub-micron spatial resolution have emerged as useful instruments because they offer a unique opportunity to observe the interior of an undamaged sample in greater detail. In this report, we examined damaged hair shaft tips using hard X-ray microscopy with a 90 nm spatial resolution. The results of this study suggest that hard X-ray microscopy is an alternative investigative method for hair morphology studies.

BACKGOUND: The late referral to nephrologist was founded as independent risk factor of poor survival in hemodialysis patients. Patients referred lately are prone to initiate dialysis urgently through temporary catheter and the use of catheter increase the incidence of catheter related complications. But patients' survival may be influenced by multiple and more complex factors beside referral pattern and use of catheter. So we planed to evaluate the effect of referral pattern on patients' survival and related factors. METHODS: This analysis included 629 incident hemodialysis patients in single center. Demographical, clinical, laboratory data were collected retrospectively. Early referral was defined as first nephrology visit over 3 months prior to initiation of dialysis. Clinical characteristics were compared between early (ER) and late referral groups (LR). Survival analysis and Cox models were performed to assess the relationship of referral pattern and mortality. Significant differences were defined as p value less than 0.05. RESULTS: ER included 269 patients and their mean age, male proportion were not different from those of LR. In ER, pre-dialysis education program and nutritional counseling were offered much more than LR and lesser catheter usage, higher serum albumin at the initiation of dialysis. ER survived longer but in Cox models, only older age, presence of diabetes, lower serum albumin at the initiation of dialysis were independent risk factor for death (odds ratio 1.047, 1.547, 0.615, respectively) CONCLUSION: Although early referral decrease catheter use at the initiation and urgent hemodialysis, classical risk factors such as old age, presence of diabetes, nutritional status at the initiation are more important in patients prognosis.
