Background:
Since September 2015, the initiation of antiviral therapy (AVT) for patients with chronic hepatitis B (CHB)-related cirrhosis has been reimbursed according to the revised Korean Association for the Study of Liver (KASL) guideline, if the patient had hepatitis B virus DNA level ≥ 2,000 IU/L, regardless of aminotransferase or alanine aminotransferase levels. This study investigated whether the KASL guideline implementation reduced the risk of CHB-related hepatocellular carcinoma (HCC) in patients with cirrhosis in South Korea.
Methods:
A total of 429 patients with CHB-related cirrhosis who initiated AVT between 2014 and 2016 were recruited. The risk of HCC development was compared between patients who initiated AVT before and after September 2015 (pre-guideline [n = 196, 45.7%] vs. postguideline implementation [n = 233, 54.3%]).
Results:
Univariate analysis showed that AVT initiation before guideline implementation, older age, male gender, and diabetes significantly predicted increased risk of HCC development (all P < 0.05). Subsequent multivariate analysis showed that AVT initiation before guideline implementation (HR = 1.941), older age (HR = 5.762), male gender (HR = 2.555), and diabetes (HR = 1.568) independently predicted increased risk of HCC development (all P < 0.05). Additionally, multivariate analysis showed that AVT initiation before guideline implementation (HR = 2.309), male gender (HR = 3.058), and lower platelet count (HR = 0.989) independently predicted mortality (P < 0.05). The cumulative incidences of HCC and mortality were significantly higher in patients who initiated AVT before guideline implementation than in those who initiated AVT after guideline implementation (all P < 0.05, log-rank test).
Conclusion
The prognosis of patients with CHB-related cirrhosis who initiated AVT improved after guideline implementation according to the revised KASL guideline.

BACKGROUND: Understanding the burden of disease is important to establish cost-effective treatment strategies and to allocate healthcare resources appropriately. However, little reliable information is available regarding the overall economic burden imposed by chronic obstructive pulmonary disease (COPD) in Korea. METHODS: This study is a multicenter observational research on the COPD burden in Korea. Total COPD costs were comprised of three categories: direct medical, direct non-medical, and indirect costs. For direct medical costs, institutional investigation was performed at 13 medical facilities mainly based on the claims data. For direct non-medical and indirect costs, site-based surveys were administered to the COPD patients during routine visits. Total costs were estimated using the COPD population defined in the recent report. RESULTS: The estimated total costs were approximately 1,245 million US dollar (1,408 billion Korean won). Direct medical costs comprised approximately 20% of the total estimated costs. Of these, formal medical costs held more than 80%. As direct non-medical costs, nursing costs made up the largest percentage (39%) of the total estimated costs. Costs for COPD-related loss of productivity formed four fifths of indirect costs, and accounted for up to 33% of the total costs. CONCLUSION: This study shows for the first time the direct and indirect costs of COPD in Korea. The total costs were enormous, and the costs of nursing and lost productivity comprised approximately 70% of total costs. The results provide insight for an effective allocation of healthcare resources and to inform establishment of strategies to reduce national burden of COPD.

BACKGROUND: Psoriasis is an immune-mediated, chronic inflammatory disease affecting multiple aspects of patients' lives. Its epidemiology varies regionally; however, nationwide epidemiologic data on psoriasis depicting profile of Korean patients has not been available to date. OBJECTIVE: To understand nationwide epidemiologic characteristics and clinical features of adult patients with psoriasis visited university hospitals in Korea. METHODS: This multicenter, non-interventional, cross-sectional study recruited 1,278 adult patients with psoriasis across 25 centers in Korea in 2013. Various clinical data including PASI, BSA, DLQI, SF-36 and PASE were collected. RESULTS: A total of 1,260 patients completed the study (male:female=1.47:1). The mean age was 47.0 years with a distribution mostly in the 50s (24.9%). Early onset (<40 years) of psoriasis accounted for 53.9% of patients. The mean disease duration was 109.2 months; mean body mass index was 23.9 kg/m²; and 12.7% of patients had a family history of psoriasis. Plaque and guttate types of psoriasis accounted for 85.8% and 8.4%, respectively. Patients with PASI ≥10 accounted for 24.9%; patients with body surface area ≥10 were 45.9%. Patients with DLQI ≥6 accounted for 78.8%. Between PASI <10 and PASI ≥10 groups, significant difference was noted in age at diagnosis, disease duration, blood pressure, waist circumference of female, and treatment experiences with phototherapy, systemic agents, and biologics. CONCLUSION: This was the first nationwide epidemiologic study of patients with psoriasis in Korea and provides an overview of the epidemiologic characteristics and clinical profiles of this patient population.

BACKGROUND/AIMS: This study evaluated the clinical outcomes of balloon-occluded retrograde transvenous obliteration (BRTO) for the treatment of hemorrhage from gastric varices (GV) in Korean patients with liver cirrhosis (LC). METHODS: We retrospectively analyzed data from 183 LC patients who underwent BRTO for GV bleeding in 6 university-based hospitals between January 2001 and December 2010. RESULTS: Of the 183 enrolled patients, 49 patients had Child-Pugh (CP) class A LC, 105 had CP class B, and 30 had CP class C at the time of BRTO. BRTO was successfully performed in 177 patients (96.7%). Procedure-related complications (e.g., pulmonary thromboembolism and renal infarction) occurred in eight patients (4.4%). Among 151 patients who underwent follow-up examinations of GV, 79 patients (52.3%) achieved eradication of GV, and 110 patients (72.8%) exhibited marked shrinkage of the treated GV to grade 0 or I. Meanwhile, new-appearance or aggravation of esophageal varices (EV) occurred in 54 out of 136 patients who underwent follow-up endoscopy (41.2%). During the 36.0+/-29.2 months (mean+/-SD) of follow-up, 39 patients rebled (hemorrhage from GV in 7, EV in 18, nonvariceal origin in 4, and unknown in 10 patients). The estimated 3-year rebleeding-free rate was 74.8%, and multivariate analysis showed that CP class C was associated with rebleeding (odds ratio, 2.404; 95% confidence-interval, 1.013-5.704; P=0.047). CONCLUSIONS: BRTO can be performed safely and effectively for the treatment of GV bleeding. However, aggravation of EV or bleeding from EV is not uncommon after BRTO; thus, periodic endoscopy to follow-up of EV with or without prophylactic treatment might be necessary in LC patients undergoing BRTO.

Nicolau syndrome is a rare adverse reaction and characterized by the acute onset of necrosis of the skin and soft tissue following intramuscular drug injection. Conservative treatments with dressings, debridement, and pain control are the mainstay of therapy. Surgical intervention such as skin graft is rarely required. We report a case of 21-year-old man with this syndrome on the right buttock after an intramuscular injection of diclofenac in which skin graft was necessary. The lesion eventually required debridements and split-thickness skin graft for reconstruction because it was very extensive and not successfully treated by the conservative method for four months.

Carcinosarcoma is a biphasic tumor that has both epithelial as well as mesenchymal components. It most commonly occurs at the esophagus, lung, upper respiratory tract and urinary bladder, however it rarely occurs on the skin. A 62-year-old men presented with a bean sized crusted ulcer on his right cheek. A biopsy specimen revealed atypical sqamous cells mixed with spindle-shaped cells with hyperchromatic nuclei. Furthermore, immunohistochemical study showed positive reactions for AE1/AE3, cytokeratin7, epithelial membrane antigen and vimentin, but negative reactions for S100 protein, CD34 and smooth muscle actin. Based on these histopathological and immunohistochemical findings, we diagnosed this case as cutaneous carcinosarcoma. The patient was treated with complete excision and a local flap.

PURPOSE: This study evaluated the usefulness of a new scoring system in diagnosing acute appendicitis which expresses the patient's symptoms, physical examination, and laboratory findings more clearly and objectively. METHODS: A prospective study was conducted with 314 patients who were hospitalized with suspicion of acute appendicitis. After analyzing the symptoms, physical examination, and laboratory findings, 10 meaningful variables were selected, each of which were scored separately. The diagnostic value of the new scoring system was evaluated, and analyzed in comparison to the preexisting Alvarado score. RESULTS: Ten variables including vomiting, migration pain, fever, Dunphy's sign, Rovsing's sign, tenderness, rebound tenderness, increased white blood cell counts, increased neutrophil proportion, and increased CRP levels were associated with acute appendicitis. The new scoring system is developed by applying 1 point for each variable, with a total score of 10 points. In the new scoring system, a score above 5 points had sensitivity of 0.75, specificity of 0.73, positive predictive value of 0.92, and diagnostic accuracy of 0.71. The area under the receiver operating characteristic curve was 0.80, which is larger than 0.72 of the preexisting Alvarado score, and thus has a higher diagnostic accuracy. As acute appendicitis progresses, the average score tends to become significantly higher (P=0.001). CONCLUSION: The new scoring system, which objectively reflects the clinical variables of the patient's symptoms, physical examination and laboratory findings, will be useful in accurately diagnosing acute appendicitis and in quickly deciding a therapeutic policy in patients with right lower abdominal pain.

Alternaria is a common saprophytic fungus found in the environment such as soil, air, and a variety of objects. The cutaneous infection caused by this fungus occurs more frequent in patients with immunocompromission than in immunocompetent people. We report a case of cutaneous alternariosis in a 63-year-old woman presented with a tender erythematous patch on the right forearm. She was on medication only for hypertension. Histopathologic examination showed a dermal mixed-cell infiltrate including multinucleated giant cells. PAS staining revealed fungal elements in the dermis. Microscopic examination of the colonies showed muriform conidia. A diagnosis of cutaneous infection due to Alternaria species was made on the basis of the above mentioned findings. Oral administration of fluconazole revealed resolution of her cutaneous lesion.
