We aimed to compare the immune response induced by natural infection with 2009 pandemic influenza A/H1N1 (pH1N1) virus and by monovalent pH1N1 vaccination in children and adolescents. This cross-sectional clinical study was conducted at 3 hospitals in Korea from February to May 2010. A total of 266 healthy subjects aged from 6 months to 18 yr were tested for the presence of the antibody against pH1N1 using hemagglutination inhibition (HI) test. Information about pH1N1 vaccination and laboratory-confirmed pH1N1 infection history was obtained. The overall rate of HI titers of > or = 1:40 against pH1N1 was 38.7%, and the geometric mean titer (GMT) was 20.5. Immunogenicity of pH1N1 vaccination only was reflected by a 41.1% of seroprotection rate and a GMT of 22.5. Immunogenicity of natural infection only was reflected by a 61.0% of seroprotection rate and a GMT of 40.0. GMT was significantly higher in the subjects of natural infection group than in the subjects of pH1N1 vaccination group (P < 0.001). The immune responses induced by natural pH1N1 infection exceed those induced by pH1N1 vaccinations.

PURPOSE: To correlate high-resolution CT (HRCT) findings with smoking history and pulmonary function test (PFT) in patients with idiopathic pulmonary fibrosis (IPF) with or without coexisting emphysema. MATERIALS AND METHODS: The study included 24 patients who had undergone HRCT and in whom IPF had been confirmed pathologically (n=7) and clinically (n=17). The patients included 19 men and 5 women aged between from 44 and 78 (mean 59) years. HRCT findings were reviewed by two radiologists and assessed for the presence and extent of emphysema (CT emphysema score ; CES) and honeycombing (CT honeycombing score ; CHS). CES and CHS were retrospectively correlated with smoking status and pulmonary function test. RESULTS: Evidence of emphysema was seen on HRCT in 20 of 24 patients with IPF (83 %). CES was 14.3 and CHS was 18.1 in smokers with IPF, as compared with 1.8 and 6.7 in nonsmokers (p < 0.01). Pulmonary function tests showed lower percent predicted FEV1 (69.3 %), FVC (64.7 %), TLC(73.7 %), and RV (77.3 %), a lower percent predicted diffusing capacity of carbon monoxide (58.2%), and normal FEV1/FVC (99.1%). The pulmonary function test in smokers showed higher TLC and RV than in nonsmokers. Eight of nine patients whose CES was higher than their CHS, as seen on HRCT, were smokers and had a smoking history of 33.1 pack-years. Seven of 15 whose CHS was higher than their CES were smokers and had a smoking history of 16.8 pack-years. In patients with a higher CES than CHS pulmonary function test results showed normal TLC (85 %) and RV (100.7%) ; this contrasted with decreased TLC (72 %) and RV (68 %) in patients whose CHS was higher than their CES. CONCLUSION: Emphysema is a frequently associated finding in patients with IPF, as seen on HRCT, and emphysema is more frequent and extensive in smokers with IPF than non-smokers. HRCT is useful for detecting emphysema in patients with IPF, and the extent of emphysema on HRCT correlates with the results of the pulmonary function test and smoking status.

PURPOSE: We wanted to evaluate the effective methods that are appropriate for an endemic area of thyroid disease and to compare the differences of cytologic diagnostic rates with and without using a peculiar smear technique. MATERIALS AND METHODS: We analyzed the incidence rate of insufficient results, complications and the total procedure times of 1,126 thyroid nodules in 776 patients who underwent US-FNAB (ultrasonography-guided fine-needle aspiration biopsy) from January to December 2005. We compared the diagnostic rate between the two groups; the groups' tests were performed with a peculiar smear technique (Group A, n = 313) or with a conventional smear technique (Group B, n = 250). RESULTS: According to the size of the thyroid nodule, the incidence rate of an insufficient result on US-FNAB and the mean total procedure time for 1126 thyroid nodules in 776 patients were measured as 16.9% (52/308) and 208 seconds for nodules under 0.5 cm, 9.8% (30/306) and 160 seconds for nodules between 0.5 cm-1.0 cm, and 6.0% (30/504) and 134 seconds for nodules over 1.0 cm. These 776 patients showed no significant complications, except for mild pain. In Group A, the incidence rate of an insufficient result was calculated as 15.1% (14/93) for the group with nodules under 0.5 cm, 5.3% (5/95) for the group with nodules between 0.5 cm-1.0 cm, 4.8% (6/125) for the group with nodules over 1.0 cm, and 8.0% (25/313) for the total A Group. In Group B, the incidence rate of an insufficient result was measured as 33.3% (15/45) for the group with nodules under 0.5 cm, 28.1% (25/89) for the group with nodules between 0.5 cm-1.0 cm, 21.4% (24/112) for the group with nodules over 1.0 cm, and 25.7% (63/245) for the total B group. There was a statistically significant correlation between the rate of an insufficient result and the peculiar smear technique or the size of the thyroid nodule. CONCLUSION: We consider that US-FNAB is very simple, safe and accurate diagnostic method for thyroid nodules, and US-FNAB with a peculiar smear technique is able to increase the diagnostic rate for thyroid nodules.

Kartagener's syndrome is an inherited condition characterized by triad of chronic paranasal sinusitis, situs inversus, and bronchiectasis. Since 1976, Afzelius found a lack of dynein arm in immotile spermatozoa by electron microscopy, numerous recent studies have focused on the ultrastructural defect in the cilia and reported that the variety type of ultrastructural defect in immotile cilia syndrome. We report a female patient who had the Kartagener's triad with rare multiple ultrastructural defect of cilia in one patient. The electron microscopic examination showed partial dynein arm defect, loss of radial spoke, microtubular transposition, and giant cilia.

Hypertension is a well-known degenerative disease whose prevalence rate increases with age. Management of high blood pressure is a critical concern in preventive strategies to reduce the morbidity and mortality for cardiovascular disease. The purpose of this study was to examine the dietary characteristics of hypertensive program participants, and to establish strategies based on their nutritional needs. Hypertensive patients were enrolled in the program in a public health center or in a local elderly center, at Suwon, in 1999-2000. Trained dietitians interviewed 62 enrollees(24-hour recall) and related variables. Mean body mass index of the subjects was 25.0kg/m2. 30.7% of the subjects had a family history of hypertension. The majority of them ate regularly and partook of all available side dishes. They consumed grains and vegetables regularly, but seldom ate dairy products or food prepared with oil. Male enrollees frequently consumed more processed food and animal fat than did female enrollees(p<0.05). An analysis of the percentage of RDA(Recommended Dietary Allowances of Korea 1995) showed that but for ascorbic acid, enrollees consumed nutrients below the RDA. The food group intake pattern was not diverse, thus only 8.1% of enrollees consumed all food groups in a day. An analysis of eating attitude showed that 64.5% of enrollees always added salt to beef soup. Male enrollees showed low food-related self-efficacy compared to female enrollees, especially with reference to reduction of instant food intake(p<0.01), increase in vegetable intake(p<0.01), reduction of monosodium glutamate(MSG) intake(p<0.01). and not overeating(p<0.05). Their perceived barriers for participating in hypertension nutrition programs included lack of time, program necessity non-recognition, and program comprehension difficulty. These results suggest that nutrition education program necessity non-recognition, and program comprehension difficulty. These results suggest that nutrition education programs for community hypertensive patients should focus on increasing participant consumption of foods, expecially dairy products, and desirable eating attitudes. It also suggests that the program should consider should consider encouraging self-efficacy in changing eating behavior.

Perinatal cardiac tumors are rare and the vast majority are histologically benign. Clinical manifestations depend on their size and location. Most of them are clinically unimportant but an arrhythmia or a cardiac failure may present as a feature of obstruction of the outflow tract. Cardiac rhabdomyoma is the most common type of the cardiac tumor and associated with the tuberous sclerosis, and may be the only sign of the tuberous sclerosis, especially, in fetus. We report a case of a cardiac tumor detected during routine prenatal ultrasonographic evaluation, which demonstrated features of rhabdomyoma. After birth, the newborn was diagnosed as tuberous sclerosis with brain MRI scanning.

PURPOSE: We conducted a prospective comparative clinical study to determine the field efficacy of the 2010-2011 influenza vaccines [Influenza virus strains; A/California/7/2009 (H1N1), A/Perth/16/2009 (H3N2), B/Brisbane/60/2008] in healthy Korean children under 18 years of age. METHODS: In this study, we enrolled subjects aged between 6 months and 18 years and divided them into 2 study groups: a group who received the influenza vaccines (407 subjects), and a control group who did not receive the influenza vaccines (230 subjects). Ours was a multicenter study that involved 7 hospitals, including the Korea Cancer Center Hospital. The study was conducted between September 2010 and February 2011. We collected nasal wash or throat swab samples from subjects who presented with acute febrile respiratory or influenza-like illnesses at the hospital. We used PCR to confirm the presence of the influenza virus in the respiratory samples and characterize the virus type. RESULTS: In this study, we collected 22 respiratory samples from the influenza-vaccinated group and found 3 cases of influenza virus infection. Similarly, we collected 21 samples from the control group and found 12 cases of influenza virus infection among 10 subjects during the study period. We determined the field efficacy of the 2010-2011 seasonal influenza vaccines to be 83.2% in healthy Korean children and adolescents. CONCLUSION: In this study, we determined the field efficacy of the 2010-2011 seasonal influenza vaccines in healthy Korean children and adolescents. We found that the field efficacy of 2010-2011 seasonal influenza vaccines was adequate.
