BACKGROUND: Tumor necrosis factor(TNF)-alpha and Interleukin(IL)-1beta are thought to play a major role in the pathogenesis of the septic syndrome, which is frequently associated with adult respiratory distress syndrome(ARDS). In spite of many reports for the role of TNF-alpha in the pathogenesis of ARDS, including human studies, it has been reported that TNF-alpha is not sensitive and specific marker for impending ARDS. But there is a possibility that the results were affected by the diversity of pathogenetic mechanisms leading to the ARDS because of various underlying disorders of the study group in the previous reports. The purpose of the present study was to evaluate the roles of TNF-alpha and IL-lbeta as a predictable marker for development of ARDS in the patients with septic syndrome, in which the pathogenesis is believed to be mainly cytokine-mediated. METHODS: Thirty-six patients of the septic syndrome hospitalized in the intensive care units of the Asan Medical Center were studied. Sixteens suffered from ARDS, whereas the remaining 20 were at the risk of developing ARDS(acute hypoxemic respiratory failure, AHRF). In all patients venous blood sample were collected in heparin-coated tubes at the time of enrollment, at 24 and 72 h thereafter. TNF-alpha and IL-lbeta was measured by an enzyme-linked immunosorbent assay (ELISA). All data are expressed as median with interquartile range. RESULTS: 1) Plama TNF-alpha levels: Plasma TNF-beta levels were less than 10pg/mL, which is lowest detection value of the kit used in this study within the range of the mean+/-2SD, in all of the normal controls, 8 of 16 subjects of ARDS and in 8 in 20 subjects of AHRF. Plasma TNF-alpha levels from patients with ARDS were 10.26pg/mL(median;<10-16.99pg/mL, interquartile range) and not different from those of patients at AHRF(10.82, <10-20.38pg/mL). There was also no significant difference between pre-ARDS(<10, <10-15.32pg/mL) and ARDS(<10, <10-10.22pg/mL). TNF-alpha levels were significantly greater in the patients with shock than the patients without shock(12.53pg/mL vs. <10pg/mL) (P<0.01). There was no statistical significance between survivors(< 10, <10-12.92pg/mL) and nonsurvivors(11.80, <10-20.8pg/mL) (P=0.28) in the plasma TNF-alpha levels. 2) Plasma IL-lbeta levels: Plasma IL-1beta levels were less than 0.3ng/mL, which is the lowest detection value of the kit used in this study, in one of each patients group. There was no significant difference in IL-1beta levels of the ARDS(2.22, 1.37-8.01ng/mL) and of the AHRF(2.13, 0.83-5.29ng/mL). There was also no significant difference between pre-ARDS(2.53, <0.3-8.34ng/mL) and ARDS(5.35, 0.66-11.51ng/mL), and between patients with septic shock and patients without shock (2.51, 1.28-8.34 vs 1.46, 0.15-2.13ng/mL). Plasma IL-19 levels were significantly different between survivors(1.37, 0.4-2.36ng/mL) and nonsurvivors(2.84, 1.46-8.34ng/mL). CONCLUSION: Plasma TNF-alpha and IL-1beta level are not a predictable marker for development of ARDS. But TNF-alpha is a marker for shock in septic syndrome. These result could not exclude a possibility of pathophysiologic roles of TNF-alpha and IL-1beta in acute lung injury because these cytokine could be locally produced and exert its effects within the lungs.

Thyrotoxic periodic paralysis (TPP) is associated with hypokalemia and occurs sporadically and usually in young adult males. We report ten cases with TPP ; all were males, mean onset age was 32.4 years old. The duration of attack. Varied from 10 to 18 hours. The distribution of paralysis was confined to limb muscles; more severe in proximal limbs and lower extremities. Potassium levels during acute attack correlated with the severity of paralysis and ECG changes, but not with the severity of decrease in TSH level. In all cases, administration of potassium salts was successful in treatment of acute attack. A patient had further attack in spite of euthyroid state under the treatment of thyrotoxicosis for one year. Another patient was free from paralytic attacks by chronic administration of the potassium salt and acetazolamide without treatment of thyrotoxicosis.

The principal objective of this study was to acquire basic data regarding the mycelial growth characteristics for the artificial cultivation of Coprinus comatus. 12 URP primers were employed to evaluate the genetic relationships of C. comatus, and the results were divided into three groups. Among six kinds of mushroom media, MYP medium was selected as the most favorable culture medium for C. comatus. The optimal temperature and pH ranges for the mycelial growth of C. comatus were 23~26degrees C and pH 6~8, respectively. The carbon and nitrogen sources for optimal mycelial growth were sucrose and tryptone, respectively.

Two case reports discussing Korean ginseng-induced allergic reactions have been published; both were inhalation-induced respiratory allergies in occupational settings. In this report we discuss the first case of anaphylaxis that developed after an oral intake of ginseng, confirmed by an open oral challenge, a skin prick test (SPT), and a basophil activation test (BAT). A 44-year-old man experienced rhinorrhea and nasal stiffness, followed by respiratory difficulty with wheeze and abdominal pain 10 minutes after oral intake of fresh ginseng. He had suffered from episodes of allergic rhinitis during the spring season for several years. Upon presentation, a physical examination, chest radiograph, and routine laboratory tests were unremarkable. Total serum IgE level was 41 IU/mL. The SPT results showed strong positive responses to alder, birch pollens, and ginseng extracts (1:500 w/v). The methacholine bronchial challenge test revealed a positive result at PC20 of 5.83 mg/mL. The open oral challenge was performed using 50 g of fresh ginseng and showed immediate onset of facial flushing, cough, respiratory difficulty with wheeze, and abdominal pain combined with a significant decrease in FEV1 levels (54% from the baseline). Serum-specific IgE and IgG4 antibodies were not detectable by enzyme-linked immunosorbent assay. BAT showed a remarkable increase in the expression of CD203c and CD63 with the addition of ginseng extract in a dose-dependent manner, while no changes were noted in the controls. In conclusion, oral intake of Korean ginseng could induce anaphylaxis, which is mediated by non-IgE-dependent direct activation of basophil/mast cells.

Pseudomyxoma Peritonei is a condition in which, as a result of ruptured mucinous tumors of the ovary or appendix, the peritoneal surface and omentum are involved with mucin secreting cells. This is a rare disease which occurs predominantly in middle aged women, characterized by histologically benign but whicth is clinically malignant. We have experienced a case of Pseudomyxoma Peritonei due to rupture of borderline mucnous tumor of the ovary and report with a brief review of literatures.

OBJECTIVE: We assessed the characteristics of Capgras syndrome in patients diagnosed as probable Alzheimer disease, and compared the clinical and imaging findings with other previous reports. METHODS: We obtained medical records of patients with Capgras syndrome diagnosed as probable Alzheimer disease in three hospitals from March 2009 to March 2010. The basic characteristics, neuropsychologic tests, brain imaging data were investigated. RESULTS: The mean age of the patients was 74.7 years old and all of the patients experienced this syndrome in relation to a spouse. Brain magnetic resonance imaging showed mild-to-moderate global atrophy, variable hippocampal atrophy in this study. The Mini-Mental State Examination mean scores were 18.78 and clinical dementia rating scores were from 1 to 2. All of the patients took medicine of acetycholine esterase inhibitors and two patients recovered with antipsychotic medication. Five patients had showed continuous Capgras syndrome, at the last follow-up day, for a year. CONCLUSION: Capgras syndrome patients in this study who were diagnosed as probable Alzheimer disease showed similar results to the individuals from other reports. More study is needed to estimate the numbers and characteristics of patients with this syndrome.

OBJECTIVE: This study was aimed to evaluate the recent trends in contraceptive use among Korean adolescents. METHODS: Data reviewed were from the 2013–2015 Korean Youth Risk Behavior Web-based Survey, which is a stratified, multistage-sampling designed online-based research project performed annually by the Korean government to ensure a nationally representative sample of Korean adolescence. Eight questions related to the topic of contraception were reviewed for the outcome variables. RESULTS: A total of 212,538 adolescents attending middle school and high school participated in the survey, and 8,755 students among them who were sexually active were included in the study. The percentage of contraceptive use showed a steady increase from 39% in 2013 to 48.7% in 2015; however, the proportion of adolescents who have never used any kind of contraception still remains high. Highly effective methods such as oral contraceptives and intrauterine devices were used by only 10% to 15% of sexually active adolescents. CONCLUSION: The present study demonstrates the status of contraceptive use among Korean adolescents. Our data have the potential to help healthcare providers to formulate policies and develop interventions for encouraging effective contraceptive use among sexually active Korean adolescents.

BACKGROUND: CD44 is a cell surface adhesion molecule which has been implicated in various biologic functions as lymphocyte homing and activation, cellular migration and extracellular matrix adhesion. Over-expression of CD44v8- 10 has been found in several cancers and is considered to be associated with tumor progression and metastasis. Recently, a novel molecular method, CD44v8- 10/CD44v10 competitive reverse transcription-polymerase chain reaction(RT-PCR) has been developed for detecting cancer cells over-expressing CD44v8-10. METHODS: We analyzed from benign and malignant pleural effusion and ascites by CD44 competitive RT-PCR and compared to the conventional cytology. RESULTS: The CD44 competitive RT-PCR analysis showed that all the 24 samples associated with benign disease presented a predominant expression of the CD44v10 transcript (v8-10/v10 ratio: 0.126-0.948), whereas 6 of 7 malignant pleural samples associated with cytology positive cancer expressed the CD44v8-10 transcript (v8-10/v10 ratio > 1.00). CONCLUSION: These results indicate that CD44 competitive RT-PCR assay is a useful and adjunct to cytological examination in cancer diagnosis, especially in detecting exfoliated cancer cells in pleural effusion.

Hepatoblastoma is the most common primary malignant liver tumor encountered during childhood. Complete surgical resection is the most important factor in predicting which children would achieve cure. Some chemotherapy regimens are effective in reducing tumor size, often rendering initially unresectable lesions amenable to complete surgical resection, and dramatically improving disease-free survival. Liver transplantation provides an additional treatment option for patients whose tumor remains unresectable even after preoperative chemotherapy. We report a case of unresectable hepatoblastoma in a child who underwent living related liver transplantation with pre and post-operative chemotherapy.

Interstitial lung disease (ILD) with autoantibodies against antisynthetase may occur in the absence of clinically apparent myositis. We report 58-year-old woman who initially presented with dyspnea. The patient showed positive immunologic markers reflecting systemic lupus erythematosus, destructive polyarthritis, Raynaud's phenomenon, and ILD. There is no proximal muscle weakness in her symptoms. This syndrome was confirmed by positive antibodies to Jo-1. For the early diagnosis of this syndrome, the possibility of this syndrome including other connective tissue disease should be considered in patients presenting with symptoms related to ILD and positive anti-nuclear antibody.
