RESUMEN
Allergic rhinitis is the most common chronic disease worldwide. Various upper airway symptoms lower quality of life, and due to the recurrent symptoms, multiple treatments are usually attempted rather than one definitive treatment. There are alternatives to medical (medication-based) and nonmedical treatments. A guideline is needed to understand allergic rhinitis and develop an appropriate treatment plan. We have developed guidelines for medical treatment based on previous reports. The current guidelines herein are associated with the “KAAACI Evidence-Based Guidelines for Allergic Rhinitis in Korea, Part 1: Update in pharmacotherapy” in which we aimed to provide evidence-based recommendations for the medical treatment of allergic rhinitis. Part 2 focuses on nonpharmacological management, including allergen-specific immunotherapy, subcutaneous or sublingual immunotherapy, nasal saline irrigation, environmental management strategies, companion animal management, and nasal turbinate surgery. The evidence to support the treatment efficacy, safety, and selection has been systematically reviewed. However, larger controlled studies are needed to elevate the level of evidence to select rational non-medical therapeutic options for patients with allergic rhinitis.
RESUMEN
Background/Aims@#Although the number of domestic adverse drug reactions (ADRs) reported in Korea is rapidly increasing, the analysis of ADRs in cancer patients remains limited. We sought to investigate the clinical features of ADRs in cancer patients. @*Methods@#ADR data were collected from a spontaneous reporting system at single university hospital, between July 2010 and June 2015. ADR cases assessed to be “unlikely” or “unclassifiable” as per the criteria of the World Health Organization-Uppsala Monitoring Center were excluded. Additional medical information was retrospectively collected from chart reviews, and clinical features of ADRs were analyzed. @*Results@#In total, 1,455 cases were reported. Of these, 822 ADRs (52.1%) were observed in cancer patients. The mean age of cancer patients was 60.8 years (range, 17–90 years), and 45.9% were male. The most prevalent clinical features were gastrointestinal abnormalities (32.6%), such as nausea and vomiting, followed by skin (28.5%) and neurologic manifestations (26.0%). Fifty-one (6.2%) and 296 cases (36.0%) were classified as severe and moderate, respectively. The most common causative agents were parenteral nutrition (PN) supplements (40.4%), followed by antibiotics (17.8%), analgesics (16.7%), iodinated contrast media (ICM, 10.6%), and vitamins (3.9%). Antineoplastic agents were responsible for 2.9% of cases. PN supplements were commonly associated with severe reactions. @*Conclusion@#Although it is well known that antibiotics, ICM, and analgesics induce ADRs, PN supplements, vitamins, and antineoplastic agents should also be considered as common causes of ADRs in cancer patients. Further investigation and monitoring to determine the causality associated with these agents is required.
RESUMEN
Acrodematitis enteropathica is an uncommon disease due to zinc deficiency which is characterized by perioral and acral dermatitis, alopecia, and diarrhea. This disease typically presents in infants, either due to an autosomal recessive genetic disorder or after cessation of breastfeeding. Acquired adult-onset acrodermatitis enteropathica has rarely been reported so far. We report a case of a 38-year-old man who had a history of chronic alcohol intake and presented with severe acrodermatitis enteropathica. The patient was successfully managed with zinc supplement and supportive care.

PURPOSE: We investigated the causes, clinical features, and risk factors of bee venom anaphylaxis in Korea. METHODS: The medical records of the diagnosis of anaphylaxis during a 5-year period from the 14 hospitals in Korea have been retrospectively reviewed. Cases of bee venom anaphylaxis were identified among anaphylaxis patients, and subgroup analyses were done. RESULTS: A total of 291 patients were included. The common cause of bee species was vespid (24.6%) in bee venom anaphylaxis, followed by honeybee and vespid (8.8%), apitherapy (7.7%), and honeybee (2.0%), although the causative bee species were commonly unknown (56.9%). The severity of anaphylaxis was mostly mild-moderate (72.9%), and common clinical manifestations included cutaneous (80.6%), cardiovascular (39.2%), respiratory (38.1%), and gastrointestinal (13.1%) symptoms. Portable epinephrine auto-injectors were prescribed to 12.1% of the patients. Subject positive to both vespid and honeybee showed more severe symptoms and higher epinephrine use (P<0.05). The severity was significantly associated with older age, but not with gender, underlying allergic disease, or family history. Apitherapy-induced anaphylaxis showed a higher rate of hospitalization and epinephrine use than bee sting anaphylaxis (P<0.05). CONCLUSION: Vespid is the most common cause of bee venom anaphylaxis in Korea. It is suggested that positivity to honeybee and vespid may be associated with more severe symptoms.

PURPOSE: The sensitization rate to Japanese Hop (Hop J) in respiratory allergy patients has increased in recent years in Korea. We evaluated changes in the allergenic potency of Hop J pollen collected in 1998 and 2009. METHODS: Thirty-five patients with allergic rhinitis and/or asthma were enrolled. Group I included 21 subjects sensitized to Hop J at an initial visit and group II included 14 subjects who developed a new sensitization. Hop J pollens were collected in 1998 and 2009 (98 and 09 extracts) and both urban and suburban environments (urban and suburban extracts). Serum specific IgE levels to Hop J pollen extracts were compared using an enzyme-linked immunosorbent assay (ELISA). IgE binding components were compared by IgE immunoblot analysis. RESULTS: Serum specific IgE levels to the 09 and urban extracts in both groups increased significantly compared to those of the 98 and suburban extracts. IgE immunoblot demonstrated that the major 10 kDa allergen was intensified in group I, while it was newly generated in group II with additional components ranging from 12-95 kDa. When the 98 and 09 extracts were compared, intensification of the major allergen of 09 extract had occurred in both groups. The IgE binding components of the urban extract was stronger than those of suburban one. CONCLUSIONS: The allergenic potency of Hop J pollen may be increased with environmental changes.

Rice is the major staple food in a large part of the world, especially in Asia. Hypersensitivity reactions to rice are rare. Moreover, cases of occupational allergies induced by inhalation of rice powder are uncommon. We report a 31-year-old male with work-related rhinitis and conjunctivitis symptoms caused by occupational exposure to rice powder in the grain industry. He showed positive responses to rice extracts on a skin prick test, and a high level of serum specific IgE to rice was detected by ELISA. Occupational rhinitis was confirmed by a nasal provocation test with rice extracts. An IgE ELISA inhibition test showed cross-creativity between rice and various grass pollen extracts. These findings suggest that the inhalation of rice powder can induce IgE-mediated occupational rhino-conjunctivitis, which may be derived from cross-reactivity to major grass pollens.
