PURPOSE: Asthma in the elderly (EA; ≥ 65 years of age) is increasing, adding a heavy socioeconomic burden to the healthcare system. However, little is known about risk factors associated with acute exacerbations in EA patients. The objective of this study was to investigate risk factors for acute exacerbation in EA compared to non-elderly asthma (NEA).METHODS: We combined data from 3 adult asthma cohorts under a unified protocol and database. Asthmatic patients with regular follow-up during a 1-year period were selected from the cohorts to identify the risk factors predicting acute exacerbations in EA compared to NEA.RESULTS: We selected a total of 1,086 patients from the merged cohort. During the observation period, 503 and 583 patients were assigned to the EA and NEA groups, respectively. The exacerbation rate was 31.0% in the EA and 33.2% in the NEA group. Multivariate logistic regression analysis revealed fixed airway obstruction, chronic rhinosinusitis (CRS), and male sex as independent risk factors for exacerbation in the EA group. In the NEA group, exacerbation increased along with an increase in eosinophil count. Bayesian analysis of the interactions among clinical factors revealed that forced expiratory volume in 1 second/forced vital capacity was directly related to exacerbation in the EA group, and eosinophil count was related to exacerbation in the NEA group.CONCLUSIONS: We suggest that fixed airway obstruction and CRS as the important clinical factors predicting acute exacerbations in EA, whereas in NEA, eosinophil count was the strong predictor of exacerbation.

Eosinophilic fasciitis is a rare disease characterized by diffuse fasciitis with peripheral eosinophilia and progressive induration and thickening of the skin and soft tissues. We report a 19-year-old female who presented with pitting edema in both lower extremities. She had a history of excessive physical activity before her symptoms developed. Physical examination revealed 2+ pitting edema in both lower legs. She complained of mild pain in both knee joints and feet, with no tenderness or heating sensations. Laboratory results were unremarkable except for severe eosinophilia. Parasite infection, venous thrombosis, and cardiac and renal problems were excluded. A magnetic resonance imaging study of both lower extremities revealed increased signal intensity in the subcutaneous lesions, consistent with superficial inflammation of the fascia. Mixed perivenular lymphoplasmacytic and eosinophilic infiltration in the subcutaneous lesion were observed on biopsy. The patient was treated with corticosteroids, resulting in remarkable improvement in both edema and eosinophilia.

BACKGROUND/AIMS: Stomach cancer can be easily diagnosed via endoscopy, but also possible to be missed. The aim of this study was to investigate the clinical and endoscopic characteristics of advanced gastric cancers that were not diagnosed based on endoscopic examination. METHODS: We evaluated patients who had newly diagnosed advanced gastric cancer that was undetected via endoscopy within the last six months. RESULTS: Sixteen patients were included in this study. The locations of the cancers were the cardia in six cases, the greater curvature side of the body in eight cases and the antrum in two cases. The histological findings were tubular type adenocarcinoma in 11 cases, with ten cases of moderately to poorly differentiated adenocarcinoma and five cases of signet ring cell type adenocarcinoma. CONCLUSIONS: Even advanced gastric cancer lesions may not be detected during endoscopy. If a patient continues to complain of upper gastrointestinal symptoms, even though endoscopy does not find abnormal findings, repeated endoscopy and/or additional diagnostic studies should be considered.

PURPOSE: Inappropriate cuff inflations cause many complications. A conventional pilot balloon palpation technique is insufficient to detect high cuff pressures, but is still preferred. Hence, we conducted this study to identify effectiveness, preference and ease of use of a new estimation technique named "passive release technique" for endotracheal tube cuff inflation. METHODS: Twenty-nine nurses inflated cuffs by a pilot balloon palpation technique in manikins inserted with a 7.5 mm endotracheal tube. Then, being educated about passive release techniques, they inflated cuffs using such a passive release technique. Intracuff pressures and air volumes were measured by manometers and syringes. Preference and ease of use between the two methods were scored using a 10-point Likert scale. RESULTS: For the pilot balloon palpation technique, only 4 nurses (13.8%) inflated cuffs within the normal range of pressures (normal: 15 to 30 mb) with an average of 39.3+/-34.0 cmH2O. For the passive release technique, 19 nurses (65.5%) inflated cuffs within the normal range of pressures with an average of 24.2+/-9.3 cmH2O (McNemar's test, p<0.01). In the pilot balloon palpation technique, inflated air volumes of 7.8+/-2.0 ml were not significantly different from inflated air volumes 8.5+/-1.2 ml (p=0.07) for the passive release technique. But the difference was found to be statistically significant in a variance ratio test (F-test) (p<0.01). In view of preference and ease of use between the two methods, mean values were not statistically different, 7.3+/-2.0 vs. 7.0+/-2.0 and 7.0+/-2.3 vs. 7.3+/-2.4, respectively. CONCLUSION: When direct intracuff measurement is not available, a passive release technique using a syringe is an effective and easy method to achieve cuff inflation.

BACKGROUND/AIMS: Alcoholic hepatitis is an acute or acute-on-chronic inflammatory syndrome associated with significant morbidity and mortality. Traditionally, Maddrey discriminant function (DF) score and Child-Turcott- Pugh (CTP) score have been used for stratifying the prognosis of alcoholic hepatitis. Recently, the model for end-stage liver disease (MELD) score has been applied to alcoholic hepatitis and some investigators consider MELD score as a better prognostic indicator for severe alcoholic hepatitis. Therefore, this analysis was aimed to compare MELD score with DF and CTP scores for predicting the short-term mortality in Korean patients with alcoholic hepatitis. METHODS: The medical records of patients hospitalized with alcoholic hepatitis between January 1, 1999 and December 31, 2004 at Hanyang University Guri-Hospital were analyzed retrospectively. RESULTS: Of the 138 medical records reviewed, 74 cases fulfilled the inclusion criteria (61 males and 13 females; mean age 47.1 years). Twelve patients (16.2%) died within 90 days after admission. Univariate analysis demonstrated that variables such as ascites, hepatic encephalopathy, splenomegaly, international normalized ratio, CTP, and DF scores were significantly correlated with increased 90-day mortality while MELD score was not. According to the multivariate analysis, only CTP score was statistically significant (p=0.012) while DF and MELD scores were not significant for predicting 90-day mortality. The survival analysis with Cox regression test showed higher DF and CTP scores, but not MELD score, significantly increased the risk of in-hospital mortality. CONCLUSIONS: This study demonstrates that DF and CTP scores are independent predictors of short-term mortality in patients with alcoholic hepatitis.

Propylthiouracil (PTU) is known to be a potential cause of antineutrophil cytoplasmic antibody (ANCA) positive small vessel vasculitis, resulting in glomerulonephritis and diffuse alveolar hemorrhage (DAH). Herein, we describe a 25-year-old pregnant woman who developed a perinulcear ANCA (p-ANCA) and myeloperoxidase ANCA (MPO-ANCA) positive DAH during PTU therapy. The patient improved after corticosteroid therapy and discontinuation of the PTU. Methimazole was prescribed in spite of the risk of recurrence of DAH because of the pregnancy. The patient is currently free from pulmonary problems. Our case shows that the alternative agent, methimazole, can be used to treat hyperthyroidism in a pregnant patient with PTU associated DAH.

In Crohn's disease, neurologic complications such as cerebrovascular accident, headache, peripheral neuropathy have been reported sporadically. The pathogenesis of these neurologic complications is still unknown and controversial. We experienced a 22-year-old man, with Crohn's disease accompanied by optic neuritis. Loss of visual acuity was developed during the worsening course of enterocutaneous fistula. After high dose steroid treatment, his visual acuity and neurologic symptoms improved immediately.

Macroenzymes are normal enzymes complexed with an immunoglobulin (usually IgG, rarely IgA or IgM). A number of macroenzymes have been reported in the literature. Among them, macro-AST has been detected in diseases such as acute and chronic hepatitis, various malignancies and autoimmune diseases, but usually not associated with any specific disease. We report a case of elevated AST activity in serum due to marco-AST formation in a female with chronic hepatitis C which was confirmed by AST isoenzyme electrophoresis. To our knowledge, this is the first report of macro-AST occurred in chronic hepatitis patient in Korea.

Percutaneous liver biopsy is well established for the diagnosis and follow-up of many liver diseases. Although it is rather safe, major complications, such as bleeding into the peritoneal or thoracic cavity, hemobilia, enteric perforation and intrahepatic hematoma, have been reported related to the procedure. Recently, incidence of such major complications has been decreased since the introduction of ultrasonography-guided liver biopsy. We report a case of 59-year-old female patient with acute cholecystitis secondary to hemobilia 2 days after ultrasonography-guided percutaneous liver biopsy.

Percutaneous approaches, such as percutaneous ethanol injection and radiofrequency ablation, have been most widely used for hepatocellular carcinoma patients who were not eligible for surgery. New technologies to improve the efficacy are currently needed. 166Holmium is a neutron activated radionuclide, and has several beneficial radiophysical characteristics for internal radiation therapy. 166Holmium-Chitosan complex, in which chitosan is chelated with 166Holmium, was developed as a radiopharmaceutical for cancer therapy. We have conducted a pilot study to evaluate the clinical efficacy of transarterial administration of 166Holmium-Chitosan complex in patients with a single and small (< 3 cm) hepatocellular carcinoma. 166Holmium-Chitosan complex, at a dose of 20 mCi per cm of tumor mass-diameter, was administered through the artery that directly fed the tumor. Twelve patients were treated with a median follow-up duration of 26 (range: 12-61) months. The tumor diameter ranged between 1.5 and 2.5 cm. Ten patients (83%) had complete response and two (17%) had partial response. The median complete response duration was not reached. The median AFP level declined from 83.8 to 8.3 ng/mL within 2 months after treatment. No grade III/IV toxicity was observed. Grade I and II toxicities were observed in four patients (2 abdominal pain, 1 fever, and 1 AST/ALT elevation). No toxic death occurred. This preliminary study shows a promising and durable complete response rate with an acceptable safety profile. Further studies with greater accrual of patients are warranted.
