RESUMEN
Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and severe adverse drug reaction characterized by the cutaneous eruption, fever, eosinophilia, and involvement of internal organs. It is commonly caused by aromatic anticonvulsant drugs and antibiotics in children. In this study, we presented a case of a 9-year-old boy with bipolar disorder, who developed DRESS syndrome after lamotrigine intake for 10 days. Thereafter, lamotrigine was discontinued, and systemic corticosteroid treatment was pursued for 18 days. After 3 months, a patch test for lamotrigine was performed as a confirmatory test to check drug reaction. Reports of DRESS syndrome in adults have increased over the past decade due to the increasing use of lamotrigine as a new aromatic anticonvulsant. Although there are only a few lamotrigine-related DRESS syndrome reports in children, caution is needed with its potential widespread use in the future.
RESUMEN
PURPOSE: Childhood asthma has a considerable social impact and economic burden, especially in severe asthma. This study aimed to identify the proportion of childhood asthma severity and to evaluate associated factors for greater asthma severity. METHODS: This study was performed on 667 children aged 5–15 years with asthma from the nationwide 19 hospitals in the Korean childhood Asthma Study (KAS). Asthma was classified as mild intermittent, mild persistent, and moderate/severe persistent groups according to the National Asthma Education and Prevention Program recommendations. Multinomial logistic regression models were used to identify the associated factors for greater asthma severity. RESULTS: Mild persistent asthma was most prevalent (39.0%), followed by mild intermittent (37.6%), moderate persistent (22.8%), and severe persistent asthma (0.6%). Onset later than 6 years of age (adjusted odds ratio [aOR], 1.69 for mild persistent asthma; aOR, 1.92 for moderate/severe persistent asthma) tended to increase asthma severity. Exposure to environmental tobacco smoke (aOR, 1.53 for mild persistent asthma; aOR, 1.85 for moderate/severe persistent asthma), and current dog ownership with sensitization to dog dander (aOR, 5.86 for mild persistent asthma; aOR, 6.90 for moderate/severe persistent asthma) showed increasing trends with greater asthma severity. Lower maternal education levels (aOR, 2.32) and no usage of an air purifier in exposure to high levels of outdoor air pollution (aOR, 1.76) were associated with moderate/severe persistent asthma. CONCLUSIONS: Modification of identified environmental factors associated with greater asthma severity might help better control childhood asthma, thereby reducing the disease burden due to childhood asthma.

Honey is a food ingested worldwide. Allergic reaction to honey is rare and only a few cases have been reported in the literature. A 20-month-old boy developed angioedema 30 minutes after eating rice cake containing honey. After 2 weeks, we performed food challenge tests with honey which resulted in anaphylaxis. This is the first case report on anaphylaxis to honey in Korea.
RESUMEN
Patient education is important for successful management of atopic dermatitis; however, due to limited time and resources, patient education remains insufficient. This study aimed to investigate the current state of education provided by Korean dermatologists, pediatric allergists, and allergists to patients with atopic dermatitis. A questionnaire survey consisting of items regarding educational programs for patients with atopic dermatitis was conducted via e-mail. In total, 153 participants responded to the questionnaires, and 26.8% indicated that they have had separate educational programs. The workforce involved in the educational program included nurses, residents or fellows, dieticians, pharmacists, and clinical psychologists. Most education protocols addressed the characteristics and natural course of atopic dermatitis and environmental management. Overall, 96.7% of the participants replied that an additional charge is needed for education; moreover, additional assistance from an academic society or association, in the form of medical staff, organized data, and advertisement, is required to develop and provide a well-structured educational program. A standardized education protocol will effectively provide appropriate education for patients with atopic dermatitis. Arrangement of education fees, covered by the National Health Insurance Service, will lead to the establishment of a structured educational program and participation of an additional medical workforce.

PURPOSE: Adherence is a major component of successful medical treatment. However, non-adherence remains a barrier to effective delivery of healthcare worldwide. METHODS: Twenty healthcare facilities (secondary or tertiary hospitals) belonging to the Korean Academy of Pediatric Allergy and Respiratory Diseases (KAPARD) participated. Questionnaires were given to patients currently receiving treatment in the form of inhalant useor oral intake or transdermal patch for mild to moderate asthma. RESULTS: A total of 1,838 patients responded to the questionnaire. Mean age was 5.98 ± 3.79 years (range: 0-18 years). With help from their caregivers, the percentage of patients that answered “taking as prescribed” was 38.04% for inhalant users, 50.09% for oral medication users and 67.42% for transdermal users. Transdermal patch users had significantly greater adherence compared to the other 2 groups (P < 0.001). The 34.15% of inhalant users, 70.33% of oral medication users and 93.00% of transdermal patch users felt that their medication delivery system was “Easy” or “Very easy” to use (P < 0.001). “Method of administration” was deemed to be the most difficult part of the treatment regimen to follow, and 76.7% of patients preferred once-daily administration (i.e., “Frequency of administration”). CONCLUSIONS: Asthma medication adherence in young children was found to be better in the transdermal patch group. This may be due to requiring fewer doses and easy to follow instructions. From an adherence point of view, the transdermal patch seems more useful for long-term asthma control in children compared to oral or inhaled medicine.

PURPOSE: Croup is known to have epidemics in seasonal and biennial trends, and to be strongly associated with epidemics of parainfluenza virus. However, seasonal and annual epidemics of croup have not been clearly reported in Korea. This study aimed to examine the seasonal/annual patterns and etiologies of childhood croup in Korea during a consecutive 6-year period. METHODS: Pediatric croup data were collected from 23 centers in Korea from 1 January 2010 to 31 December 2015. Electronic medical records, including multiplex reverse transcription polymerase chain reaction (RT-PCR) results, demographics and clinical information were cross-sectionally reviewed and analyzed. RESULTS: Overall, 2,598 childhood croup patients requiring hospitalization were identified during the study period. Among them, a total of 927 who underwent RT-PCR were included in the analysis. Males (61.5%) predominated, and most (63.0%) of them were younger than 2 years of age (median, 19 months; interquartile range, 11–31 months). Peak hospitalization occurred in 2010 and 2012 in even-numbered years, and parainfluenza virus (PIV, 39.7%) was the most common cause of childhood croup requiring hospitalization, followed by respiratory syncytial virus (14.9%), human rhinovirus (12.5%), Mycoplasma pneumonaie (10.6%), and human coronavirus (7.3%). CONCLUSION: It is concluded that croup hospitalization has a biennial pattern in even-numbered years. PIV may be the most common cause of childhood croup; however, croup epidemics could be attributed to other viruses.

PURPOSE: Recently, the prevalence and disease burden of asthma have increased. Thus, the need for early diagnosis and appropriate management of asthma is emerging. However, it is difficult to identify the diagnosis, symptoms and the prevalence of asthma due to lack of reliable investigating items. The purpose of this study was to develop a standardized survey format in order to assess the prevalence of asthma in Koreans. METHODS: We investigated surveys and related information that are utilized to assess asthma diagnosis and prevalence by systematic review. After that, Delphi survey was conducted on 44 Korean allergists in order to develop a standardized survey in Korea. The process consisted of 3 serial rounds across 3 age groups. Each subsequent round narrowed investigating items for the decision of standard set about asthma prevalence, current asthma, and asthma aggravation. RESULTS: Lifetime asthma was defined as “ever doctor-diagnosed asthma” in all age groups. Current asthma was defined as “treatment for asthma during the past 12 months” in all age groups, and “doctor-diagnosed asthma during the past 12 months” was added on the ≥5-year-old and adult groups. “Wheezing ever” was defined as “wheezing at any time in the past,” and current wheeze was defined as “wheezing in the last 12 months.” Asthma aggravation was defined as “visits at the emergency department or admission due to asthma attack within the last 12 months” in all age groups. CONCLUSION: We established applicable nationwide definitions of “lifetime asthma,” “current asthma,” and “asthma aggravation” in Koreans by the Delphi survey.

PURPOSE: Mycoplasma pneumoniae (MP) is a common cause of community-acquired pneumonia (CAP) in children. MP serum IgM and polymerase chain reaction (PCR) are the methods that enable early diagnosis in patients with MP pneumonia. The objective of this study was to investigate the clinical value of serum MP-specific IgM antibodies in PCR-positive MP pneumonia for the early diagnosis of MP pneumonia in children with CAP. METHODS: Out of 129 patients with lower respiratory tract infection aged over 3 years, 90 CAP children were enrolled in the study. Throat swab MP real-time PCR and serum enzyme-linked immunosorbent assays (ELISA) IgM antibodies were performed. A positive rate of MP PCR and serum IgM, the level of IgM index, clinical features, and laboratory findings were analyzed. RESULTS: PCR was positive in 57 cases. Longer fever duration before admission (P < 0.001), higher rates of lobar or segmental pneumonia (P=0.048), unilateral infiltration (P=0.038), and extrapulmonary symptoms (P=0.049) were associated with MP PCR-positive pneumonia. Serum IgM index was significantly higher in MP PCR-positive pneumonia them in MP PCR-negative pneumonia (3.9±3.0 vs. 0.8±1.3, P < 0.001). Using MP PCR as a gold standard, the sensitivity, specificity, positive predictive value and negative predictive value of serum IgM were 85.5%, 82.1%, 91.4%, and 71.9%, respectively. The area under the curves for serum IgM index was 0.892, and the ROC analysis indicated that an optimal cutoff value of 1.05 for serum IgM provided the highest sensitivity and specificity interestingly (83.9% vs. 85.7%, P < 0.001). CONCLUSION: Serum IgM ELISA has useful diagnostic value in PCR-positive MP pneumonia. Applying an IgM index cutoff of 1.05 improves diagnostic accuracy.

PURPOSE: This study aimed to evaluate the diagnostic value of radiologic findings in children with suspected foreign body aspiration. METHODS: A retrospective medical chart review was done on 32 children with suspected foreign bodies in terms of age, sex, symptoms, signs, bronchographic findings, and type and location of foreign bodies. The diagnostic value of radiography was analyzed: 29 with chest anteroposterior (AP) or posteroanterior (PA) view, 23 with chest lateral decubitus view, 27 with chest computed tomography (CT), 29 with chest AP, PA or chest lateral decubitus view, and 25 with bronchoscopy. RESULTS: As a measure for detecting foreign body aspiration, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of radiologic findings were: chest AP or PA view, 50%, 100%, 100%, 29.4%, and 58.6%, respectively; chest lateral decubitus view, 57.9%, 50.0%, 84.6%, 20.0%, and 56.5%, respectively; chest AP, PA or chest lateral decubitus view, 69.6%, 66.7%, 88.8%, 36.4%, and 69.0%, respectively; and chest CT, 100.0%, 85.7%, 95.2%, 100.0%, and 96.2%, respectively. CONCLUSION: There is clinical benefit to take chest radiographs to diagnose foreign body aspiration. However, based on the results of this study, it may be not necessary to take chest lateral decubitus to diagnose foreign body aspiration. If chest radiographs show unilateral hyperinflation, foreign body aspiration can be diagnosed. In cases of normal chest radiography and history of a witnessed choking episode combined with positive signs, the diagnosis of airway foreign body aspiration should be made by using chest CT.

Identifying allergic sensitization is important for the proper diagnosis and management of allergic diseases. Skin prick testing and measuring serum specific IgE antibodies are standard tests to confirm allergic sensitization. Skin prick testing has many advantages, but it is difficult to perform on young children. Serum specific IgE can be easily performed on young children, but it can be performed only up to 12 antigens in patients younger than 6 years due to insurance coverage. Therefore, it is important to select appropriate antigens for the patients. Appropriate allergens may vary depending on the patient's age, accompanying disease, and residential area, so that detailed history taking is essential for proper allergen selection. In this review, we will discuss considerations for selecting appropriate allergens for clinicians when performing an allergy test on difficult-to-test children under 6 years of age.

PURPOSE: To identify the correlation between nasal eosinophilia and aeroallergen sensitization in children and adolescents. METHODS: This is a retrospective study of patients below 18 years of age who had a history of rhinitis that lasted more than 2 weeks or had been repeated more than once a year, received nasal eosinophil examinations, and had serum specific IgE to aeroallergens measured at an Allergy Clinic in a single tertiary teaching hospital in Seoul, Korea. The percentage of nasal eosinophils was calculated by the number of eosinophils per total leukocytes in a high-power field of 1,000×. Data was analyzed to determine the association between nasal eosinophilia and 18 aeroallergens. RESULTS: Of the 245 patients included, 156 (63.7%) were male and the mean age (±standard deviation) was 7.9 years (±3.8). In total, 175 patients (71.4%) were sensitized to at least 1 of the 18 aeroallergens tested, and sensitization to house dust mite was most common. In addition, 118 (48.2%) and 69 patients (28.2%) had nasal eosinophilia of at least 1% and 5%, respectively. There were no significant correlations between serum total IgE or age and the percentage of nasal eosinophils. However, the percentage of nasal eosinophils in the group sensitized to any aeroallergens was significantly increased compared to the nonsensitized group (P=0.002). The percentage of nasal eosinophils was significantly higher in patients who were sensitized to Birch-Alder Mix, oak white, Bermuda grass, orchard grass, timothy grass, sweet vernal grass, rye, mugwort, short ragweed, Alternaria alternata, cats, dogs or Dermatophagoides farinae compared to those nonsensitized. CONCLUSION: Nasal eosinophilia was significantly associated with sensitization to aeroallergens.

OBJECTIVES: Lidocaine, a local anaesthetic is a treatment option in uncontrolled asthma due to its immunomodulatory effects. In the present study, proparacaine (PPC), a derivative of lidocaine was examined for its therapeutic application in a mouse model of allergic rhinitis. METHODS: The mice were grouped into 4 groups: control group, allergic rhinitis (AR) group, ciclesonide (CIC) group, and PPC group. Nasal symptom scores, eosinophil counts, goblet cell counts, and mast cells counts in the nasal mucosa were measured. Serum ovalbumin (OVA)-specific immunoglobulin (Ig) E, OVA-specific IgG1, OVA-specific IgG2a, interleukin (IL)-4, IL-5, and cortisol levels were measured. RESULTS: Intranasal administration of PPC significantly decreased nasal symptoms, number of eosinophils, goblet cells, and mast cells in the lamina propria of the nasal mucosa. Serum OVA-specific IgE, OVA-specific IgG1, OVA-specific IgG2a was significantly higher in the AR compared with the control group. Serum level of IL-4 was significantly lower in the CIC group and PPC group in comparison with AR group. Serum IL-5 showed no significant difference among all groups. No significant difference in serum cortisol levels was observed among the 4 groups. CONCLUSION: PPC appears to have a therapeutic potential in treatment of allergic rhinitis in a mouse model by reducing eosinophil, goblet cell, and mast cell infiltration in the nasal mucosa.

PURPOSE: Acute lower respiratory infection (ALRI), which is frequently encountered in pediatric patients, is the leading cause of hospitalization. We aimed to identify particular cytokines that correlated with ALRI clinical characteristics. We also aimed to identify any differences in cytokines between respiratory syncytial virus (RSV)-related ALRI and non-RSV-related ALRI. METHODS: Cytokine levels were measured in the sera sampled from 103 pediatric patients diagnosed with ALRI and admitted to Seoul St. Mary's Hospital between May 2012 and April 2013. The correlations between cytokine levels and the length of hospitalization, the number of days with fever, body temperature, pulse rate, respiration rate, oxygen saturation upon admission, and duration of oxygen supplementation were analyzed. RESULTS: In children with ALRI, the level of interleukin (IL)-6, granulocyte-colony stimulating factor (G-CSF), and IL-10 were correlated with a higher body temperature on admission. In addition, the IL-8 level was correlated with pulse rate and respiration rate, and IL-1β level was related with oxygen saturation on admission. In children with RSV-related ALRI, the IL-6 was correlated the with duration of fever, and the IL-1β, IL-2, and IL-8 levels were related to pulse rate and respiration rate. In addition, the increase in interferon-gamma-inducible protein-10 (IP-10) level was correlated with a higher body temperature on admission and a longer duration of hospitalization in children with RSV-related ALRI. CONCLUSION: In children with ALRI, the levels of IL-6, IL-8, IL-1β, G-CSF, and IP-10 were correlated with its clinical features. In children with RSV-related ALRI, the IL-1β, IL-2, IL-6, IL-8, and IP-10 level was correlated with the severity of the disease.

PURPOSE: Guidelines need to be tailored to where they are applied. We aimed to describe the distinctive asthma severity profile and the pattern of controller prescription in Korean children. METHODS: Twelve pediatric allergists from tertiary medical centers reviewed medical records of all asthmatic children who visited their clinics between September 1 and November 30 of 2013. Controller prescriptions were re-classified into 4 categories, then the prevalence of each asthma severity category and the controller prescription patterns according to asthma severity assessed by a Western (Global Initiative for Asthma, GINA) and an Asia-Pacific (Japanese Pediatric GuideLine, JPGL) guideline were evaluated. RESULTS: A total of 840 cases were reviewed. Both GINA and JPGL revealed that 328 (39.0%) and 249 (29.6%) subjects had intermittent asthma whereas 24 (2.9%) and 21 (2.5%) subjects had severe persistent asthma, respectively. Although higher category controllers tended to be prescribed to those who had more severe asthma, there was much overlap in categories of prescribed controllers between groups with regard to asthma severities. Leukotriene receptor antagonists (LTRA) was the most frequently prescribed as a single controller (40%) or as an add-on medication (19%) in the group of asthmatic children <6 years. CONCLUSIONS: Korean children have distinctive patterns of asthma severity and management strategies with a lower prevalence of severe asthma and a preference toward LTRA rather than low dose inhaled corticosteroids (ICS) alone or add-on long-acting beta-agonist (LABA) in the group of <6 year-old asthmatics that has not been predicted in Western countries. Thus, strategies tailored to regional situations need to be developed and recommended.

PURPOSE: To assess the usefulness of flexible bronchoscopy in patients with suspected pulmonary tuberculosis (PTB) who have difficulty in sputum expectoration. METHODS: The subjects of this study were patients who were suspected of PTB and visited the Division of Pediatric Pulmonology at a tertiary hospital from April 2006 to March 2016. PTB suspects were determined by clinical symptoms, radiologic findings, and immunologic studies. We aimed to examine the value and safety of bronchoscopy in diagnosis and differential diagnosis of PTB in PTB-suspected patients. The diagnostic criteria for PTB were defined when Mycobacterium tuberculosis was cultured in the sputum specimen or in the bronchial washing fluid. RESULTS: A total of 19 PTB suspects were included. One patient was diagnosed with PTB by using the sputum study. However, the remaining 18 patients could not expectorate sputum or showed no evidence of Mycobacterium tuberculosis infection from the sputum study. Of the 18 patients, 15 underwent bronchoscopy. After bronchoscopy, 6 patients were diagnosed with PTB and 9 patients were diagnosed with Mycoplasma, viral, or fungal pneumonia, and tumors. For antituberculous drug resistance, there were 1 case of isoniazid (INH) resistance and 1 case of concurrent resistance to INH and prothionamide. There was no multidrug-resistant tuberculosis. None of the patients had significant complications due to bronchoscopy. CONCLUSION: Flexible bronchoscopy appears to be a definitive and safe procedure for the differential diagnosis of patients suspecting PTB in children who have difficulty expectorating sputum.

PURPOSE: This study was performed to investigate the indications, yield, and complications of flexible bronchoscopy for respiratory disease in children compared to earlier domestic studies and to examine if any differences existed in comparison to international studies. METHODS: The medical records of 100 cases of flexible bronchoscopy that were performed in 76 patients at the Department of Pediatrics of The Catholic University of Korea, Seoul St. Mary's Hospital from June 16, 2010 to August 6, 2013 were reviewed. RESULTS: A total of 76 patients (50 males and 26 females) were included in the study. The most common indication of flexible bronchoscopy was persistent pneumonia or pneumonia in immunocompromised patients (53 cases). The object of flexible bronchoscopy was accomplished in 65 of 100 cases, and, the treatment was changed in 24 of 65 cases. The most common abnormal finding was tracheomalacia that was found in 18 cases. In 67 cases where bronchoalveolar lavage was performed, bacteria were identified in 47 cases, fungi in 9 cases, and viruses in 22 cases. Complications occurred in 8 cases. CONCLUSION: Compared to earlier domestic studies, there was no significant change in diagnostic approaches and therapeutic improvement. However, this study showed that flexible bronchoscopy appears to be safe in patients with hemato-oncologic disease. Compared to international studies, the occurrence of complications due to flexible bronchoscopy was relatively low.

PURPOSE: Recent studies have shown that interferon-gamma-inducible protein of 10 kDa (IP-10/CXCL10) levels is increased in acute bronchiolitis and asthma. The aim of this study was to examine the levels of IP-10 in children with wheezing and whether it correlates with other clinical variables. METHODS: A total of 62 subjects children were hospitalized for lower respiratory tract infection with wheezing and visited the Emergency Department due to an acute exacerbation of asthma. IP-10 levels were measured using enzyme-linked immunosorbent assay in the serum collected at admission. Serum IP-10 levels were evaluated for the relationships with age, sex, blood eosinophils counts, acute phase reactant, allergic sensitization, history of wheezing, and chest X-ray findings. RESULTS: Age showed a significant negative correlation with serum IP-10 levels (P=0.002). The serum levels of IP-10 were also significantly increased in patients with pneumonic infiltration on X-rays compared to those with normal or hyperinflation (P<0.009). There was no significant difference in the serum IP-10 level according to the other factors, including allergic sensitization. CONCLUSION: Serum IP-10 is significantly associated with inflammation of the lung and age, but not with allergic inflammation.

PURPOSE: This study aimed to have a deeper insight into the clinical spectrum of foreign body aspiration in children and to prospect the further clinical implications of early diagnosis. METHODS: We conducted a retrospective medical chart review of 48 children with foreign bodies at The Catholic University of Korea, Seoul St. Mary's Hospital, between January 2009 and December 2013 in terms of age, sex, symptoms and signs, radiologic findings, and clinical courses. Patients were divided into 2 groups according to the time from aspiration to a definite diagnosis. The 2 groups were compared for clinical courses, radiologic findings, and the length of hospitalization. RESULTS: Approximately 85% of patients were 3 years of age or younger. About one-fifth of patients had no history of foreign body aspiration. Cough and coarse breathing sounds were the most common symptoms and signs. The most frequent radiologic finding was pulmonary air trapping (33.3%). The mostly commonly aspirated foreign body was peanut and detected in left main bronchus. Cough, sputum, and absence of aspiration history were more common in the delayed diagnosed group than in the early diagnosed group. CONCLUSION: Our results suggest that the number of accidents associated with foreign body aspiration can be reduced by keeping infants with nut formula under close observation and by conducting assertive bronchoscopic examination on children with delayed recovery from respiratory infections. After removal of foreign bodies, close monitoring and expectation of possible complications can prevent patients from a long hospital stay.

PURPOSE: Although anaphylaxis is recognized as an important, life-threatening condition, data are limited regarding its triggers in different age groups. We aimed to identify anaphylaxis triggers by age in Korean children. METHODS: We performed a retrospective review of medical records for children diagnosed with anaphylaxis between 2009 and 2013 in 23 secondary or tertiary hospitals in South Korea. RESULTS: A total of 991 cases (mean age=5.89±5.24) were reported, with 63.9% involving patients younger than 6 years of age and 66% involving male children. Food was the most common anaphylaxis trigger (74.7%), followed by drugs and radiocontrast media (10.7%), idiopathic factors (9.2%), and exercise (3.6%). The most common food allergen was milk (28.4%), followed by egg white (13.6%), walnut (8.0%), wheat (7.2%), buckwheat (6.5%), and peanut (6.2%). Milk and seafood were the most common anaphylaxis triggers in young and older children, respectively. Drug-triggered anaphylaxis was observed more frequently with increasing age, with antibiotics (34.9%) and nonsteroidal anti-inflammatory drugs (17.9%) being the most common causes. CONCLUSIONS: The most common anaphylaxis trigger in Korean children was food. Data on these triggers show that their relative frequency may vary by age.

PURPOSE: We aimed to translate the Test for Respiratory and Asthma Control in Kids (TRACK) instrument into Korean, with subsequent linguistic validation. METHODS: The multistep process of forward translation, reconciliation, back-translation, cognitive debriefing, and proofreading of the Korean version of the TRACK was completed. RESULTS: Two bilingual medical personnel independently translated the original English version of the TRACK into Korean one. After moderating the translation into a single reconciled one, 4 other bilingual persons were invited to translate the Korean draft back into an English one. Discrepancies between the original English version and the back-translated one were reviewed, and the need to modify the reconciled Korean draft was discussed. Twenty caregivers of asthmatic children took part in interviews that examine the appropriateness of the Korean version of the TRACK. The feedback from caregivers were then reviewed by a panel of pediatric allergists and reflected in the final Korean version. The document was finally proofread to check the spelling, grammar, layout and formatting. CONCLUSION: Translation and linguistic validation of the Korean version of the TRACK instrument were completed.
