PURPOSE: The recurrence of Kawasaki disease has not been considered significant and has not been reported on literatures in Korea. Authors reviewed cases with recurrent Kawasaki disease to get informations about recurrent Kawasaki disease and to know whether there is any factor, if present, that can predict recurrence. METHODS: We reviewed and analyzed the hospital records of patients with recurrent Kawasaki disease who had been admitted to Inha University Hospital from January 1986 through December 1994. RESULTS: The total number of cases with Kawasaki disease was 266 during that period in Inha University Hospital. Seven patients were diagnosed as having recurrent Kawasaki disease, but four of them fulfilled five or more items of the diagnostic criteria for Kawasaki disease. So the proportion of recurrent cases was 1.5%(4/259)(or 2.7% (7/259) ?). Sex ratio was M:F=3:1. The ages at the first episodes of illness were from 7 months to 3 years 2 months (median=24 months), and those of the second episodes were from 11 months to 6 years 3 months (median=4 years 3 months). The intervals between two episodes were from 4 months to 4 years 2 months (median=1 year 9 months). No special aspect could be found in the clinical and laboratory findings of primary cases, compared with other cases with kawasaki disease. The clinical manifestations and courses of recurred cases were not significantly different from those of primary cases, except one recurred case who developed coronary aneurysm. CONCLUSIONS: The recurrence rate of Kawasaki disease seems to be higher than 1.5%(or 2.7%) at least. The risk factors for recurrence could not be found, and there was no specific aspect in the clinical manifestations and courses of recurrent Kawasaki disease.

Idiopathic myelofibrosis (IMF), which is characterized by marrow fibrosis, leukoerythroblastic anemia, teardrop poikilocytosis and splenomegaly due to extrumedullary hematopoiesis, has known to have no form of therapy. On the ground of the possibility of reversing collagen deposion in IMF using 1, 25dihydroxycholecalciferol [1, 25(OH)2D3], we report here our observations of 5 patients (M:F=1:4) with IMF before and after treatment with 0.5 microgram/day of alfacalcidol, precursor of 1, 25(OH)2D3. In 3 fo 5 patients the hemoglobin rose and in 4 of 5 the platelet count increased. Follow-up marrow examination revealed that marrow trephine reticulin fibrosis decreased according as the amelioration of clinical and laboratory findings. But these did not persist except one patient in spite of the sustained use of alfacalcidol. Our results suggest that alfacalcidol may have a therapeutic role in some patients with IMF. More extensive studies will be clarify the action of alfacalcidol in IMF.

Pulmonary function test is one of the most important tools in the management of patients with respiratory tract diseases and allergic diseases. As with the difficulties in performing the test, it has been seldom used in pediatric field. But with the advent of simple, computerized tools, pediatric pulmonologist and allergist try to manage the patients using PFT. Still the normal predicted values are variable among the reports. So it is important to have normal predicted value in Korean children. From April to July 1992, pulmonary function test was performed in 965(male: 490, female: 475) primary school-aged children except <3 or >97 percentile of Korean-children Physical developemental standards with history of allergic diseases and respiratory tract diseases ay SungNam, KyongKiDo. We evaluated the predicted normal values of the FEV1.0, FVC and PEFR and logarithmic regression equation setting the predicted values by using the microspirometer of Micromedical Ltd. England that could that could be easily applied to children. 1) Predicted values of pulmonary function test items were generally higher in boys than those of girls. 2) Correlation coefficient to the parameters examined was the highest in height 0.78, then age 0.75, weight 0.70 and chest circumference 0.61.

Telepathology systems will be common systems in hospitals. The two systems were designed and implemented in web environments for test. One was implemented with the Common Object Request Broker Architecture (CORBA) technique. The other system was implemented in the form of ActiveX. The histopathological materials were stained by Hematoxylin and Eosin. By the Donpisha CCD camera attached to an Olympus BX-51 optical microscope 180 color images come to be acquired. For evaluation of the systems, transmission times and telediagnosis concordance rates were measured. Image processing ability was tested using two telepathology systems. For the local area test, system I using CORBA had measured image transmission times of 0.1 s, 0.2 s, and 0.4 s at the file sizes of 100 K byte, 900 K byte and 3.6 M byte respectively. Transmission times for system II using Component Object Model (COM) were slightly slower, ranging from 0.02 s to 0.05 s. In the long distance area test, system II transmission times were 0.5 s, 0.8 s, and 2.0 s. The overall concordance rate of telediagnosis for the 180 images was 78.3%. In this study, we compared our systems about image transmission, and processing for the further development of system configurations.

PURPOSE: Despite the increasing prevalence of allergic rhinitis, there are difficulties in early diagnosis and proper treatment due to lack of education and misunderstanding of the disease. Development of efficient education materials based on the level of awareness of allergic rhinitis is required. Therefore, this study was aimed to develop a questionnaire for investigating the level of awareness of allergic rhinitis. METHODS: Questions related to the level of awareness of allergic rhinitis were prepared on the basis of the literature, professional advice and inquiries from patients and caregivers. These items were categorized into 4 areas: (1) basic knowledge, (2) symptoms, (3) diagnosis and environmental management and (4) treatment. Through the eight preliminary survey on 38 adults, a questionnaire of 60 items was developed. The results were analyzed by using SPSS 12.0. RESULTS: A tool for investigating the level of awareness was completed, which was composed of 20 items with an internal reliability of 0.67. According to the results of the survey with 60 items, the areas of basic knowledge, symptoms and environmental management of allergic rhinitis showed high awareness. The items regarding the association between allergic rhinitis and asthma, necessity of regular checkup, awareness of maintenance treatment, importance of treatment with intranasal steroids, and the influence of treatment on immunity, growth and development of patient showed low awareness. CONCLUSION: A reliable tool was developed for investigating the level of awareness of allergic rhinitis. It may be useful in developing educational materials to optimize its educational effect on allergic rhinitis.

PURPOSE: M. pneumoniae is knwon as a common causative agents of respiratory infection in school children. But, it tends to occur in infants and younger children recently. This study was performed to evaluate the incidence and clinical manifestations of M. pneumoniae pneumonia in infants. METHOD: A total of 142 children(33 infants{Group I : Infants group; 0-2 years} and 109 children{Group II : Children group; 3-6 years}) was admitted with M. pneumoniae pneumonia from January through December 1998. We reviewed medical records and evaluated the incidence, clinical manifestations and laboratory findings. RESULT: Number of patients with M. pneumoniae pneumonia in 0 to 2 years of age(infants group) comprised 23.2% of the total in contrast to 57.1% in 3 to 6 years of age group and 19.7% in 7 to 12 years of age group. Seasonal distribution showed the highest frequency in autumn in infant and children groups(45.5% and 39.4% respectively). The most frequent symptom was cough(90.9% and 96.3%, respectively), followed by sputum(81.8% and 90.8%, respectively), fever(72.7% and 66.0%, respectively) and rhinorrhea(72.7% and 64.0%, respectively). The common physical findings on admission were crackle(84.8% and 80.7%, respectively), wheezing(30.3% and 18.3%, respectively) and throat injection(39.4% and 35.8%, respectively). WBC count was within normal range in both groups(90.9% and 89%, respectively) and CRP was lower than 0.8 mg/dL in 63.6% of infant group and 54.1% of children group. The most common radiologic finding was bronchopneumonia in both groups (47% and 38%, respectively). CONCLUSION: Number of the patients with Mycoplasma pneumoniae pneumonia in infants age from 0 to 2 years comprised 23.2% of the total. Clinical manifestations of Mycoplasma pneumonia in infants were similar to those of older children. We recommened Mycoplasma pneumoniae should be considerd as a causative agent even in infant with respiratory infection.

Immotile cilia syndrome is an inherited disorder characterized by specific ultrastructural defects of cilia and associated impairment of ciliary motion and mucociliary clearance. Disorders of ciliary structure or function result in chronic sinopulmonary diseases manifested as chronic sinusitis, bronchitis, otitis media, nasal polyposis, and ultimately bronchiectasis. In addition, situs inversus, dextrocardia, and infertility can be associated with dysfunctional ciliary activity. We experienced a case of immotile cilia syndrome presenting with recurrent bronchitis, pneumonia, chronic sinusitis, otitis media, and bronchiectasis. She was diagnosed by lack of dynein inner arm on electron microscopy. Treatment included chest percussion, bronchodilators, antibiotics, and surgical intervention. She has been followed up at regular intervals. We report this case with related literatures.

Miller-Fisher syndrome is an acute poly-neuropathy typically characterized by the triad of ophthalmoplegia, ataxia, and areflexia. Other poly-neuropathy diseases include Guillain-Barre syndrome and Bickerstaff brainstem encephalitis. However, not all cases of Miller-Fisher syndrome have the typical three symptoms. These diseases have been differentiated by clinical manifestations and anti-GQ1b IgG antibody testing. In Miller-Fisher syndrome, anti-GQ1b IgG antibody is present in over 95% of patients; however, the frequency is not so high in normal subjects or in those with other poly-neuropathy diseases. Infectious illnesses, such as respiratory diseases and gastrointestinal diseases, usually precede Miller-Fisher syndrome. In general, Miller-Fisher syndrome is a self-limiting illness; however, a few cases of Miller-Fisher syndrome progressing to respiratory failure have been reported, particularly in children. In this case, we report abnormal angiographic findings. We report a case of atypical Miller-Fisher syndrome with internal carotid artery stenosis treated with prednisolone.

PURPOSE: It is generally accepted that air pollution can cause acute respiratory diseases. This study assessed the relationship between air pollution and development of pediatric respiratory diseases in Inchon city. METHODS: We studied a number of pediatric patients who developed respiratory diseases such as bronchial asthma, bronchiolitis, URI, bronchitis and pneumonia and visited the Inha University Hospital emergency room from January to December 31 1997. We converted the data into an average per day that included meteorologic data of air pollution(such as CO, NO2, O3, SO2, and PM10) and weather data(such as atmospheric temperature, relative humidity) in three different places in Inchon city. We used a Poisson distribution, selecting a lowess statistics model. We also used the S-Plus statistics program. RESULTS: After several variables were controlled, we determined the relative risks between the incidence of pediatric respiratory diseases and air pollutants as CO=0.92, NO2=1.12, 03=1.21, SO2= 1.04, and PM10=1.00. The 95% confidence intervals were CO=0.88-0.19, NO2=1.05-1.14, O3=1.09- 1.28, SO2=1.07-1.31, and PM10=1.01-1.05. CONCLUSION: There was a significant association between the incidence of pediatric respiratory diseases and the level of air pollutants, especially NO2, O3, SO2, and PMio in Inchon city. More studies on air pollution and its effect on pediatric respiratory diseases are needed.
