1.Evaluation of Fruit Intake and its Relation to Body Mass Index of Adolescents.
Clinical Nutrition Research 2014;3(2):126-133
Diets high in fruits and vegetables are recommended to maintain health. However, accurate fruit intake evaluation is hard and high sugar content in most of the fruits suggest possible negative relationships with health indices. The purpose of the present study was to evaluate the fruit intake status of adolescents and to examine the relationship between fruit intake and body mass index (BMI). For this, 400 middle and high school students were surveyed for their fruit eating attitude, preference, and intake level for fruit along with the evaluation of their relationship with anthropometric measures. As for fruit preference, the most frequent answer was 'like very much' (60.0%) and the preference of fruit was significantly higher in females than in males (p < 0.01). The highest answer to the reason to like fruits was 'delicious' (67.0%). The highest proportion of subjects replied that the amount of fruit intake was similar in both school meals and at home (39.3%) and unlikable feeling of fruits was 'sour' (47.0%). The favorite fruit was the apple followed by oriental melon, grape, Korean cherry, cherry, tangerine/orange, hallabong, plum, mango, persimmon, peach, pear/kiwi, apricot, Japanese apricot, and fig in order. As for the number of serving sizes per person were 2.9 times/day for male students and 3.0 times/day for female students showing no significant difference. The frequency of eating fruits in the evening showed a significant positive correlation with body weight (p < 0.05) and BMI (p < 0.01), respectively. In summary of these study findings, it was found that the fruit preference of adolescents was relatively high and their fruit intake level satisfied the recommended number of intake. The number of evening fruit intake had a significantly positive correlation with body weight and BMI. Further studies are required to examine the relationship between fruit intake and health indicators.

PURPOSE: Pollen-food allergy syndrome (PFAS) is an immunoglobulin E (IgE)-mediated allergy in pollinosis patients caused by raw fruits and vegetables and is the most common food allergy in adults. However, there has been no nationwide study on PFAS in Korea. In this study, we investigated the prevalence and clinical characteristics of PFAS in Korea. METHODS: Twenty-two investigators participated in this study, in which patients with allergic rhinoconjunctivitis and/or bronchial asthma with pollen allergy were enrolled. The questionnaires included demographic characteristics, a list of fruits and vegetables, and clinical manifestations of food allergy. Pollen allergy was diagnosed by skin prick test and/or measurement of the serum level of specific IgE. RESULTS: A total of 648 pollinosis patients were enrolled. The prevalence of PFAS was 41.7% (n = 270). PFAS patients exhibited cutaneous (43.0%), respiratory (20.0%), cardiovascular (3.7%) or neurologic symptoms (4.8%) in addition to oropharyngeal symptoms. Anaphylaxis was noted in 8.9% of the PFAS patients. Seventy types of foods were linked to PFAS; e.g., peach (48.5%), apple (46.7%), kiwi (30.4%), peanut (17.4%), plum (16.3%), chestnut (14.8%), pineapple (13.7%), walnut (14.1%), Korean melon (12.6%), tomato (11.9%), melon (11.5%) and apricot (10.7%). Korean foods such as taro/taro stem (8.9%), ginseong (8.2%), perilla leaf (4.4%), bellflower root (4.4%), crown daisy (3.0%), deodeok (3.3%), kudzu root (3.0%) and lotus root (2.6%) were also linked to PFAS. CONCLUSIONS: This was the first nationwide study of PFAS in Korea. The prevalence of PFAS was 41.7%, and 8.9% of the PFAS patients had anaphylaxis. These results will provide clinically useful information to physicians.

Contact urticaria designates a local immediate and/or delayed urticaria reaction, with swelling and redness at the sites of contact with certain agents. Fruits are the frequently causative agent for immunologically mediated contact urticaria. We report herein a contact urticaria occurring in a 20-year-old male immediately aftar contact with peach and plum, and after ingestion of plum, peach and apple. Swelling and itching sensation of lips and oral cavity, and tightness of chest were also developed ofter ingestion of plum, peach and apple.

With increasing need to prevent serious food allergy reactions, Korean food allergen labeling regulation has been revised repeatedly. This paper aims to summarize current statuses of food allergen labeling in Korea and foreign countries and to analyze the issue of food allergen labeling regulation. Korean food labeling regulation currently requires 19 items and 22 foods to be reported on labels (eggs, milk, buckwheat, peanut, soybean, wheat, mackerel, crab, shrimp, pork, peach, tomato, sulfite, walnut, chicken, beef, squid, shellfish, and pine nut). However, some common food triggers (for example, almond, cashew nut, and kiwi fruit) are not included in the current labeling regulation. Another issue is that the Korean labeling regulation has not yet been fully implemented for nonprepacked foods; thus, consumers still have difficulty in correctly identifying allergenic ingredients in food. It should be assessed whether warning statements for cross-contamination are reasonable. To prevent the occurrence of serious reactions from accidental ingestion, efforts must be made to solve recently raised issues including the items required to be listed on food labels, the system of standards for labeling and display methods.

The laccase (PpLAC) gene family members in peach fruit were identified and the relationship between their expression pattern and chilling induced browning were investigated. The study was performed using two varieties of peaches with different chilling tolerance, treated with or without exogenous γ-aminobutyric acid (GABA) during cold storage. Twenty-six genes were screened from the peach fruit genome. These genes were distributed on 6 chromosomes and each contained 5-7 exons. The PpLAC gene family members shared relatively similar gene structure and conserved motifs, and they were classified into 7 subgroups based on the cluster analysis. Transcriptome sequencing revealed that the expression levels of PpLAC7 and PpLAC9 exhibited an increasing pattern under low temperature storage, and displayed a similar trend with the browning index of peach fruit. Notably, GABA treatment reduced the degree of browning and inhibited the expression of PpLAC7 and PpLAC9. These results suggested that PpLAC7 and PpLAC9 might be involved in the browning of peach fruit during cold storage.

Journal of Korean Medical Science 2018;33(33):e218-
BACKGROUND: Oral allergy syndrome (OAS) is a type of allergic reaction that mainly occurs on oral contact with raw fruit, vegetables, or nuts. The most common type of OAS is birch pollen-related food allergy. Although OAS is a common food allergy in adults, only few epidemiologic studies have been reported in Korea. Here we investigate the prevalence and triggers of birch pollen-related food allergy. METHODS: We conducted a retrospective chart review of 1,427 patients who underwent a skin prick test for inhalant allergens at the Asthma and Allergy Clinic in Seoul National University Bundang Hospital from January 2011 to December 2016. RESULTS: Of 1,427 patients, 125 (8.7%) were sensitized to birch pollen. Among them, 20.0% developed OAS, which was the most common food allergy (96.2%). The prevalence of OAS was higher in females, and was 18.2% in birch pollen-sensitized allergic rhinoconjunctivitis patients. Further, 72.0% OAS patients had rhinoconjunctivitis, 20.0% had asthma, and 12.0% had chronic urticaria. Apple (68.0%), peach (56.0%), nuts (36.0%), kiwi (20.0%), persimmon (20.0%), plum (16.0%), and cherry (16.0%) were frequent triggers; however, Chinese yam, kudzu vine, bellflower root, codonopsis, and ginseng were also revealed as triggers. Patients (60.0%) showed OAS with ≥ 3 foods at the same time. Only 3 patients showed mono-sensitivity to birch pollen, while others were multi-sensitized to trees, grasses, weed, or house dust mite allergens. CONCLUSION: OAS was the most common food allergy in birch pollen-sensitized patients. This study revealed the unique triggers of OAS in Korea in addition to well-known triggers.

PURPOSE: Recently, component-resolved diagnosis (CRD) using microarray technology has been introduced to the field of clinical allergy. This study was aimed to investigate the clinical usefulness of microarray-based IgE detection for diagnosing clinical raw fruit allergy in birch pollen-sensitized children. METHODS: Thirty-one children with allergic disease who had been sensitized to pollen were studied. A pollen-sensitized patient was defined as having an allergen-specific history with concomitant positive skin-prick tests (SPTs) to natural allergen extracts or positive allergen-specific IgE. All subjects underwent SPTs for pollen and fruit. In all subjects, specific IgE to pollen and fruit were measured by ImmunoCAP. Specific IgE antibodies to allergen components were determined by a customized allergen microarray (ISAC). RESULTS: Thirteen of the 31 patients (41.9%) had a history of fruit hypersensitivity with positive SPTs. Measuring IgE to allergen components by ISAC, all the 13 patients with fruit hypersensitivity were positive to at least one of Mal d 1, Pru p 1, Pru p 3, Act d 8, and Act d 2 compared to 12 of the 13 patients (92.3%) who had at least 1 positive IgE to fruits (apple, peach, and kiwi) using ImmunoCAP. The sensitivity of ISAC microarray was 100.0% for the diagnosis of fruit hypersensitivity, but its specificity was 27.7% (5/18). The sensitivity of ImmunoCAP was 92.3%, and its specificity was 83.3%. CONCLUSION: The sensitivity of allergen components tested using microarray for the diagnosis of clinical fruit hypersensitivity in children with pollen allergy was high; however, its specificity was low.

The nevus sebaceus of Jadsssohn is an organoid nevus generally noted on the scalp or the face as a single lesion. A 26-year-old man has suffered from a pea sized, pedunculated cherry red colored papule on the back ground of yellowish colored verrucous plaque on the vertex. Clinically, pedunculated papule was similar to granuloma pyogenicum, but histopathologic examination showed the features of tubular apocrine adenoma with focal areas of syringocystadenoma papilliferum, suggesting that might be a variant or could be associated with syringocystadenoma papilliferum.

PURPOSE: The aim of this study was to evaluate hidden allergens of acute idiopathic urticaria (AIU) in childhood by using the component-resolved diagnostics (CRD). METHODS: We applied CRD using pathogenesis-related protein family number 10 (PR-10) and nonspecific lipid transfer proteins (nsLTP). RESULTS: Twenty-two of the 74 AIU children (29.7%) were found to be positive on CRD. Ten children were positive to nMal d 1 for apple (value range, 1.10–40.59), 6 to rConr a 1 for hazelnut (1.53–11.97), 4 to rPru p 1 for peach (1.32–11.83). 6 to rAra h 8 for peanut (1.20–8.12), 6 to nAct d 8 for kiwi (0.85–3.32), 4 to rBet v 1 for birch (2.49–54.28), and 3 to rAln g 1 for alder (2.32–5.74). Six children were positive to nPru p 3 for peach (1.45–18.77), 4 to rCor a 8 for hazelnut (2.56–9.19), 2 to nArt v 3 for mugwort (3.40–7.42), and 3 to rBet v2 to profilin of birch (2.56–17.46). Ten children with AIU were positive to multiple component proteins. For hazelnut, 5 children were positive to PR-10 (rConr a 1) and nsLTP (rConr a 1). For peach, 3 children were positive to PR-10 (rPru p 1) and nsLTP (nPru p 3). CONCLUSION: IgE sensitization to PR-10 or nsLTP may be allergen components for AIU in childhood.
