Background/Aims: We aimed to analyze the efficacy of angiotensin receptor-neprilysin inhibitor (ARNI) by the disease course of heart failure (HF). Methods: We evaluated 227 patients with HF in a multi-center retrospective cohort that included those with left ventricular ejection fraction (LVEF) ≤ 40% undergoing ARNI treatment. The patients were divided into patients with newly diagnosed HF with ARNI treatment initiated within 6 months of diagnosis (de novo HF group) and those who were diagnosed or admitted for HF exacerbation for more than 6 months prior to initiation of ARNI treatment (prior HF group). The primary outcome was a composite of cardiovascular death and worsening HF, including hospitalization or an emergency visit for HF aggravation within 12 months. Results: No significant differences in baseline characteristics were reported between the de novo and prior HF groups. The prior HF group was significantly associated with a higher primary outcome (23.9 vs. 9.4%) than the de novo HF group (adjusted hazard ratio 2.52, 95% confidence interval 1.06–5.96, p = 0.036), although on a higher initial dose. The de novo HF group showed better LVEF improvement after 1 year (12.0% vs 7.4%, p = 0.010). Further, the discontinuation rate of diuretics after 1 year was numerically higher in the de novo group than the prior HF group (34.4 vs 18.5%, p = 0.064). Conclusions The de novo HF group had a lower risk of the primary composite outcome than the prior HF group in patients with reduced ejection fraction who were treated with ARNI.

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to develop clinical practice guidelines for the surgical treatment of laryngeal cancer. This Task Force conducted a systematic search of the EMBASE, MEDLINE, Cochrane Library, and KoreaMed databases to identify relevant articles, using search terms selected according to the key questions. Evidence-based recommendations were then created on the basis of these articles. An external expert review and Delphi questionnaire were applied to reach consensus regarding the recommendations. The resulting guidelines focus on the surgical treatment of laryngeal cancer with the assumption that surgery is the selected treatment modality after a multidisciplinary discussion in any context. These guidelines do not, therefore, address non-surgical treatment such as radiation therapy or chemotherapy. The committee developed 62 evidence-based recommendations in 32 categories intended to assist clinicians during management of patients with laryngeal cancer and patients with laryngeal cancer, and counselors and health policy-makers.

BACKGROUND: Metabolic syndrome is a major health problem in postmenopausal women, along with psychological issues. Hence, this study was conducted to investigate the relationship between metabolic syndrome and mental health properties targeting middle-aged menopausal women, and analyzed the psychological factors affecting the prevalence of metabolic syndrome. METHODS: The study subjects were 479 postmenopausal women aged 45-64 years, who had taken their routine health screenings from August to October in 2012. The presence of 3 or more of 5 risk factors constitutes diagnosis of metabolic syndrome. Depression, trait anxiety, and stress level were measured by Beck Depression Inventory, State-Trait Inventory, and Brief Encounter Psychological Instrument, respectively. Multiple logistic regression analysis was performed to confirm the relationship between the metabolic syndrome and psychological characteristics. RESULTS: The prevalence of metabolic syndrome in postmenopausal women was 16.5%. Metabolic syndrome was significantly related with trait anxiety (odds ratio [OR]=16.53, P=0.007) and depression (OR=0.16, P=0.012), after adjusting for age, marital status, educational level, monthly income, body mass index, eating habits and exercise. CONCLUSIONS: Trait anxiety and depression were found to be related with the prevalence of metabolic syndrome in postmenopausal women.

Endoscopic submucosal dissection (ESD) is a widely accepted treatment for early gastric and esophageal cancer. Compared to endoscopic mucosal resection, ESD has the advantage of enabling en bloc removal of tumors regardless of their size. However, ESD can result in a large artificial ulcer, which may lead to a considerable deformity. Circumferential mucosal defects of more than three-fourths the esophageal circumference, long longitudinal mucosal defects (>30 mm), and lesions in the upper esophagus are significant risk factors for the development of post-ESD strictures of the esophagus. In the stomach, a circumferential mucosal defects more than three-fourths in extent and longitudinal mucosal defects >5 cm are risk factors of post-ESD stricture. If scheduled early, regular endoscopic balloon dilation is effective in controlling and preventing post-ESD stricture. Moreover, intralesional steroid injections or oral steroids can achieve remission of dysphagia or reduce the need for repeated endoscopic balloon dilation. However, further study is needed to improve the prevention of stricture formation.

BACKGROUND/AIMS: Surgery has been the mainstay of treatment for duodenal perforations after the introduction of endoscopic retrograde cholangiopancreatography (ERCP). Yet there have recently been arguments that conservative management with or without endoscopic intervention may be possible and safe. METHODS: For the patients who received ERCP at Inha University Hospital from Jan. 2001 to Dec. 2007, we retrospectively analyzed the clinical manifestations, the treatment and the clinical outcomes of the cases with duodenal perforation. RESULTS: Among the 1708 ERCP cases, duodenal perforation occurred in eleven (0.6%) patients. There were two cases of duodenal perforations (type I), four cases of peri-Vaterian injury (type II), two cases of bile duct perforations (type III) and three cases of retroperitoneal perforations (type IV). Six patients (55%) were treated surgically while the others were managed conservatively. Except for one death (9.1%), ten patients fully recovered. Either residual diseases or fluid collections, as seen on CT, were present in the surgically managed patients. The median time interval between ERCP and surgery was 19 hours (range: 8~30 hours). CONCLUSIONS: To decide on the management of duodenal perforation after ERCP, the presence of residual disease or the leakage of intraluminal contents should be considered along with the type of the perforation.

BACKGROUND AND OBJECTIVES: Despite relatively high incidences of follicular variant of papillary thyroid carcinoma (FV-PTC), there is a continuous debate regarding the clinical behavior, treatment outcome, prognostic variables and survival of this disease. We performed this study for the purpose of getting further understanding and more supporting ideas for the treatment of FV-PTC. SUBJECTS AND METHOD: A clinicopathologic analysis of 116 patients who underwent a thyroidectomy with a final diagnosis of FV-PTC divided the patients into three groups: the FV-PTC only group (group A, n=78), the FV-PTC group who developed classical papillary thyroid carcinoma (C-PTC) (group B, n=38) and the C-PTC only (group C, n=320, 2003, Korea Cancer Center Hospital). The three groups were compared with respect to the following various clinicopathological characteristics: age at diagnosis, tumor size, stage of tumor, capsular invasion, age, metastasis, extent, size score, multifocality of tumor, LN metastasis, treatment, and recurrence. RESULTS: The mean tumor sizes, disease stage, and type of initial surgery were similar in three groups. However, the prevalence of nodal disease and capsular invasion were significantly higher in the groups B and C compared to the patients of group A. The 8-year disease-free survival rate was 93.7% in the patients with FV-PTC only, 90.4% in the patients with C-PTC only and 88.2% in the patients with FV-PTC group, who developed C-PTC (p>0.05). CONCLUSION: The clinical behavior and prognosis of PTC and FV-PTC groups did not differ significantly. In treating FV-PTC, we find that it is desirable to choose a similar strategy as that used to treat C-PTC.

PURPOSE: The number of resected lymph nodes can influence the current N staging. This study examined the significance of the metastatic lymph node ratio on the survival of patients with pT2 gastric cancer. METHODS: The records of 176 patients who had undergone curative gastrectomy and diagnosed with pT2 gastric cancer by pathology, between February 1990 and October 2002 were retrospectively reviewed. Those patients with other organ metastases or those who had undergone a dissection of less than 15 lymph nodes were excluded. The clinicopathologic prognostic variables were evaluated using the SPSS statistical program. RESULTS: There were 115 men and 61 women with a mean age of 59 years. The median survival period was 93 months (2~184 months). Metastatic lymph nodes were found in 100 cases (56.8%), a mean of 34.6 lymph nodes were dissected, a mean of 3.2 lymph nodes metastasized, and a mean metastatic lymph node ratio of 0.09 was found. According to the UICC TNM classification, the number of stage IB (N0) cases was 76 (43.2%), stage II (N1) was 74 (42.0%), stage IIIA (N2) was 18 (10.2%), and stage IV (N3) was 8 (4.5%). The overall 5-year survival rate was 75.2%. According to the UICC TNM classification, the 5-year survival rate was stage IB, II, IIIA, and IV was 88.6%, 74.3%, 39.5%, and 33.3%, respectively. The metastatic lymph node ratio (nR) was divided into 4 categories; nR0 (76) = 0, 0 Classification ; Female ; Gastrectomy ; Humans ; Lymph Nodes* ; Male ; Neoplasm Metastasis ; Pathology ; Prognosis ; Retrospective Studies ; Stomach Neoplasms* ; Survival Rate*

While endovascular aneurysm repair (EVAR) is prevailing for the treatment of abdominal aortic aneurysm (AAA) in modern vascular practice, PURPOSE: we conducted nationwide questionnaire survey to investigate the current status of AAA treatment and their results in Korea. METHOD: We reviewed the replies from 28 hospitals (33 departments) to the questionnaire inquiring annual number, clinical features, mode of treatment and results of AAA patients during the period from Jan. 2000 to Jul. 2004. Results: 980 AAA patients were reported including 292 ruptured AAA (29.8%) and 688 non-ruptured AAA (70.2%). For treatment of AAA, 834 (85.1%) surgical repairs (SRs) and 111 (11.3%) endovascualr aneurysm repairs (EVARs) were performed while 35 patients (3.6%) died of AAA rupture before operation. The locations of AAA were infrarenal in 889 (90.7%), juxtarenal in 62 (6.3%), and suprarenal in 29 patients (3.0%). Among 834 patients undergoing SR, 577 patients (69.2%) had non-ruptured AAAs and 257 patients (30.8%) had ruptured AAAs. Mean operative mortality rate was 4.1% after elective SRs, 30.7% after SR for ruptured AAAs, and 2.3% after EVARs. The reported brand name of stent graft devices were various including domestic custom-made in 56 (50.5%), imported brand in 18 (16.2%) while 37 (33.3%) stent grafts were not reported their brand name. The frequencies of type I and III endoleaks after EVAR were reported 5.8% and 5.8% respectively in 86 patients with an available data. CONCLUSION: SR has been used as a major treatment option in Korea for the treatment of AAA patients while EVAR is increasing. The mortality rate of SR of AAA was comparable to western multi-center trial reports but mortality or morbidity rates of EVAR were unable to know in this questionnaire survey.

BACKGROUND: Intravenous administration of midazolam is widely used as a premedication for esophagogastroduonenoscopy. However, there are individual differences in midazolam doses for premedication and controversies for starting point of esophagogastroduonenoscopy after midazolam injection. There are also controversies for flumazenil injection time after esophagogastroduonenoscopy. The aims of this study were to determine the proper doses of midazolam for esophagogastroduonenoscopy and factors which affect midazolam doses. Also we evaluated the proper timing of flumazenil injection to increase patient's satisfaction according to sedation status. METHODS: 126 patients who were supposed to be taken diagnostic esophagogastroduonenoscopic exam were enrolled in this study. We evaluated the difference of patient's age, sex, alcohol consumption, sedation score, cooperation score, and satisfaction score according to midazolam doses. The relation between midazolam doses and agitation score, insomnia score, and somatic preoccupation score were checked. We evaluated the relation between midazolam doses and age, sex, alcohol consumption, amnesia, sedation, cooperation and satisfaction. RESULTS: There were no relationship between age, sex and midazolam doses. Alcoholics needed larger amount of midazolam than non-alcoholics. No differences in satisfaction were observed according to sedation status. There were significant relationship between midazolam doses and sedation score but not with satisfaction, cooperation, amnesia, agitation, insomnia and somatic preoccupation score. Patients who were injected flumazenil 20 minutes after esophagogastroduonenoscopy were more satisfied than patients who were injected flumazenil immediately after esophagogastroduonenoscopy. CONCLUSION: Minimal doses of midazolam that could induce mild sedation was enough and safe. Flumazenil injection 20 minutes after esophagogastroduonenoscopy was more efficacious than immediate injection.

PURPOSE: Surgeons are confronted frequently with the diagnostic and therapeutic challenges in the cases of acute appendicitis in the elderly. Despite the improvements in management, the morbidity and mortality remain high. In order to verify contributing factors of high morbidity and mortality and establish more proper diagnostic and therapeutic strategies, we compared the clinical characteristics and outcomes of acute appendicitis in the elderly with those of younger people. METHODS: We retrospectively reviewed medical records of 30 elderly and 248 younger people who were pathologically diagnosed as appendicitis after an appendectomy. RESULTS: There was no difference in the rates of occurrence of right lower abdominal pain and tenderness between the two people. The rate of appendiceal perforation was significantly higher in the elderly. Prehospital delay was significantly longer in the elderly. Concomitant diseases were more prevalent in the elderly. The hospital stay was significantly longer and the rate of complication was relatively higher in the elderly also. CONCLUSIONS: When a vague and unexplained abdominal discomfort occurs in the elderly, we should suspect and rule out acute appendicitis as the cause of the discomfort. Early aggressive diagnostic and therapeutic interventions are essential components in managing acute appendicitis in the elderly. In addition, perioperative evaluation and prophylactic measures for concomitant diseases are needed to decrease morbidity and mortality in the elderly.
