Background: Atherogenic dyslipidemia, which is frequently associated with type 2 diabetes (T2D) and insulin resistance, contributes to the development of vascular complications. Statin therapy is the primary approach to dyslipidemia management in T2D, however, the role of non-statin therapy remains unclear. Ezetimibe reduces cholesterol burden by inhibiting intestinal cholesterol absorption. Fibrates lower triglyceride levels and increase high-density lipoprotein cholesterol (HDL-C) levels via peroxisome proliferator- activated receptor alpha agonism. Therefore, when combined, these drugs effectively lower non-HDL-C levels. Despite this, few clinical trials have specifically targeted non-HDL-C, and the efficacy of triple combination therapies, including statins, ezetimibe, and fibrates, has yet to be determined. Methods: This is a multicenter, prospective, randomized, open-label, active-comparator controlled trial involving 3,958 eligible participants with T2D, cardiovascular risk factors, and elevated non-HDL-C (≥100 mg/dL). Participants, already on moderate-intensity statins, will be randomly assigned to either Ezefeno (ezetimibe/fenofibrate) addition or statin dose-escalation. The primary end point is the development of a composite of major adverse cardiovascular and diabetic microvascular events over 48 months. Conclusion This trial aims to assess whether combining statins, ezetimibe, and fenofibrate is as effective as, or possibly superior to, statin monotherapy intensification in lowering cardiovascular and microvascular disease risk for patients with T2D. This could propose a novel therapeutic approach for managing dyslipidemia in T2D.

PURPOSE: Many studies have reported that pollen-food allergy syndrome (PFAS) can cause anaphylaxis. No comprehensive investigations into anaphylaxis in PFAS have been conducted, however. In this study, we investigated the clinical manifestations and risk factors for anaphylaxis in PFAS in Korean patients with pollinosis. MATERIALS AND METHODS: Data were obtained from a nationwide cross-sectional study that previously reported on PFAS in Korean patients with pollinosis. Data from 273 patients with PFAS were collected, including demographics, list of culprit fruits and vegetables, and clinical manifestations of food allergy. We analyzed 27 anaphylaxis patients and compared them with patients with PFAS with oropharyngeal symptoms only (n=130). RESULTS: The most common cause of anaphylaxis in PFAS was peanut (33.3%), apple (22.2%), walnut (22.2%), pine nut (18.5%), peach (14.8%), and ginseng (14.8%). Anaphylaxis was significantly associated with the strength of sensitization to alder, hazel, willow, poplar, timothy, and ragweed (p<0.05, respectively). Multivariable analysis revealed that the presence of atopic dermatitis [odds ratio (OR), 3.58; 95% confidence interval (CI), 1.25–10.23; p=0.017]; sensitization to hazel (OR, 5.27; 95% CI, 1.79–15.53; p=0.003), timothy (OR, 11.8; 95% CI, 2.70–51.64; p=0.001), or ragweed (OR, 3.18; 95% CI, 1.03–9.87; p=0.045); and the number of culprit foods (OR, 1.25; 95% CI, 1.15–1.37; p<0.001) were related to the development of anaphylaxis in PFAS. CONCLUSION: The most common culprit foods causing anaphylaxis in PFAS were peanut and apple. The presence of atopic dermatitis; sensitization to hazel, timothy, or ragweed; and a greater number of culprit foods were risk factors for anaphylaxis in PFAS.

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.

BACKGROUND: There are practical difficulties to show exact clinical symptoms such as seizure to medical students at Clinical Performance Examination (CPX). We developed a new CPX case of child's seizure on video using smartphone.METHODS: A total of 356 4th-year students of five universities in Daegue-Gyeongbuk and Gyeongnam area took the clinical skill examination from June 13th to 17th in 2016. Among them, 72 students took the new CPX case in June 15th and 71 students filled out the questionnaire on whether the new CPX with smartphone video is helpful, authentic, difficult, and necessary for other CPX. All the questions were measured on 5-Likert scale.RESULTS: Mean score of the new CPX was 57.1, lower than the mean scores of the other 11 CPX cases, 62.8. For the question “Smartphone videos helped to solve the problem”, 45 students (63.4%) answered ‘Very much’. For the question “Is it realistic compared to other questions?” 30 students (42.3%) and 25 students (35.2%) answered ‘Very much’ and ‘Much’. For the question “Is it difficult compared with other questions?” 18 students (25.4%) and 26 students (36.6%) answered ‘Very much’ and ‘Much’. As for the question “I would like to have more tests using smartphone video”, 26 students (36.6%) answered ‘So and so’.CONCLUSION: A majority of students responded that video presentation was helpful and authentic to figure out the CPX, whereas they assessed smartphone video was more difficult compared with other CPXs. Further, students were negative toward using smartphone video for the other CPXs.

Allergic rhinitis (AR) is one of the most common chronic allergic respiratory diseases worldwide. Various practical guidelines for AR have been developed and updated to improve the care of AR patients; however, up to 40% patients remain symptomatic. The unmet need for AR care is one of the greatest public health problems in the world. The gaps between guideline and real-world practice, and differences according to the region, culture, and medical environments may be the causes of unmet needs for AR care. Because there is no evidence-based AR practical guideline reflecting the Korean particularity, various needs are increasing. The purpose of the study was to evaluate whether existing guidelines are sufficient for AR patient management in real practice and whether development of regional guidelines to reflect regional differences is needed in Korea. A total of 99 primary physicians comprising internists, pediatricians, and otolaryngologists (n=33 for each) were surveyed by a questionnaire relating to unmet needs for AR care between June 2 and June 16 of 2014. Among 39 question items, participants strongly agreed on 15 items that existing guidelines were highly insufficient and needed new guidelines. However, there was some disagreement according to specialties for another 24 items. In conclusion, the survey results demonstrated that many physicians did not agree with the current AR guideline, and a new guideline reflecting Korean particularity was needed.

In order to prevent sensitization to a new allergen and the development of asthma, practitioners may consider allergen-specific immunotherapy in patients with allergic rhinitis. Additionally, in patients with severe allergic rhinitis refractory to medication, practitioners can also consider surgical management for improving the patients' nasal symptoms. However, there are still no practical guidelines regarding the indications for immunotherapy, the appropriate selection of the allergen, and the optimal duration of therapy. Moreover, no clear indications exist for surgical treatment. Pregnant or lactating women frequently complain of symptoms of rhinitis. However, due to the fear of potential complications to their babies, they avoid medical treatment despite significant discomfort. Therefore, we present 14 answers to core questions about immunotherapy, surgical treatment, and considerations for special circumstances, such as pregnancy and lactation.

As the prevalence and socioeconomic burden of allergic rhinitis is steadily increasing every year, it is essential that clinical practitioners diagnose and manage allergic rhinitis in an evidence-based manner. Therefore, the Korean Academy of Asthma, Allergy and Clinical Immunology developed new clinical guidelines for Korean patients and practitioners. We first performed a questionnaire survey to address the core questions, about which clinical practitioners are the most curious. A large group of physicians (allergists), pediatricians, and otorhinolaryngologists developed answers for those questions by performing a systematic literature review and determining the appropriate levels of recommendation. In this article, we propose 11 answers for core questions regarding the diagnosis and differential diagnosis of allergic rhinitis.

The social and economic burden of allergic rhinitis (AR) is increasing, with significant effects on the quality of life of patients suffering from AR. Therefore, physicians require evidence-based guidelines regarding the diagnosis, differential diagnosis and proper management management of patients with AR. The Korean Academy of Asthma, Allergy and Clinical Immunology developed new clinical guidelines for the appropriate management of AR, especially in Korean patients. For the core questions (i.e. questions that most practitioners were curious about), several experts in the field of allergology, pediatrics, and otorhinolaryngology developed a set of practical guidelines based on a systematic review of the literature. Furthermore, we determined the level of evidence associated with the recommendations for each answer. In this article, we suggest 15 answers for core questions about the medical treatment of AR.
