Allergic rhinitis (AR) is defined as chronic inflammatory reactions to common allergens in the nasal mucosa with at least two AR symptoms including rhinorrhea, nasal congestion, sneezing, nasal/ocular pruritus, and postnasal drainage. AR is a common health problem, and it affects around 10-25% of general population. Its prevalence is increasing according to the environmental changes. AR and asthma frequently coexist in the same patient, therefore we should consider it and check for asthma to diagnose AR. Antihistamines and nasal corticosteroids are recommended as the 1st line treatment of AR. Decongestants may be effective for nasal congestion, and leukotrienes are helpful to improve both nasal and bronchial inflammations in patients with AR and asthma. Allergen specific immunotherapy is useful in IgE mediated AR and can prevent the progression to asthma and new sensitizations. Appropriate AR treatment including medications and immunotherapy can improve symptoms and reduce medications. Finally improvement of quality of life can be achieved.

PURPOSE: Assessment of the severity and clinical course of asthma is important for effective disease control. Cognitive and physical impairments occur due to the aging process, which may impact on asthma control. We aimed to evaluate the impact of cognitive function on the assessment of asthma control in older asthmatics as a prospective interventional trial. METHODS: A total of 50 mild to moderate asthmatics over 60 years of age were enrolled. Three questionnaires were used: the asthma control test (ACT), the asthma-specific quality of life, and the Korean version of the Short Form of the Geriatric Depression Scale. The Seoul neuropsychological screening battery-dementia version (SNSB-D), Korean version of the Mini-Mental Status Examination, and the Seoul instrumental activities of daily living scale were applied for neuropsychological assessment. RESULTS: The mean patient age was 67.0±4.9 years, and 30 patients (60.0%) were female. The sensitivity and specificity of the ACT for determining well-controlled asthma were 91.7% and 39.5%, respectively. Regarding neuropsychological assessment, 22 patients (44%) had mild cognitive impairment, 4 (8.7%) had dementia, and 17 (34%) had depression. Total SNSB-D score was significantly higher in patients with an ACT score of ≥20 (P=0.015). The ACT scores were significantly associated with SNSB-D results in analyses adjusted for age, sex, education duration, lung function, and depression (P=0.004). CONCLUSION: We found significant positive correlations between cognitive functions, as measured by SNSB-D, and asthma control status, as measured by ACT scores, in older patients with asthma. Therefore, cognitive impairment may be associated with poor asthma control in older asthmatics.

The genetic mechanism of aspirin intolerant acute urticaria (AIAU) is unknown. To demonstrate an association between the beta2 adrenergic receptor (ADRB2) polymorphism and the phenotype of AIAU, one hundred fourteen patients with AIAU, 110 patients with aspirin intolerant chronic urticaria (AICU), and 498 normal healthy controls (NC) based on a Korean population were enrolled. The genotype of ADRB2 at 46 A > G was analyzed using a direct sequencing method. The ADRB2 polymorphism at 46 A > G showed a significant difference between AIAU and NC; the frequency of the major genotype was significantly higher in the AIAU group (p= 0.017 in recessive model), while no differences were noted in allele and genotype frequencies between AICU and NC. In conclusion, the ADRB2 (46 A > G) gene polymorphism may contribute to the development of the phenotype of AIAU.

PURPOSE: The IL-4 and IL-4 receptor alpha (IL-4Ralpha) genes are the key candidate genes for atopy and asthma susceptibility. Exposure to wheat flour can cause IgE sensitization and respiratory symptoms in bakery workers. Therefore, we hypothesized that IL-4 and IL-4Ralpha single nucleotide polymorphisms (SNPs) may be involved in the pathogenic mechanism of baker's asthma. METHODS: Clinical and genetic data from 373 bakery workers were analyzed. A survey questionnaire, spirometry, and skin prick tests with wheat flour were performed. Serum-specific IgE, IgG1, and IgG4 to wheat flour were determined using ELISA. Five candidate IL-4 (-729 T>G, 589 T>C, and 33 T>C) and IL-4Ralpha (Ile75Val A>G and Gln576Arg A>G) SNPs were genotyped and analyzed. RESULTS: Workers with the G allele of IL-4Ralpha Ile75Val A>G had a significantly higher prevalence of work-related lower respiratory symptoms than those with the AA genotype (P=0.004, 16.0% vs. 2.9%). In the skin prick test, workers with the AA genotype of IL-4Ralpha Gln576Arg A>G had a significantly higher positive rate to wheat flour (P=0.015, 8.2% vs. 1.1%) than those with AG/GG genotype. No significant associations were found in the three genetic polymorphisms of IL-4. For the predicted probabilities, workers with the AA genotype of Gln576Arg A>G had a higher prevalence of IgG1 and IgG4 in response to wheat flour, according to increased exposure intensity (P=0.001 for IgG1 and P=0.003 for IgG4). CONCLUSIONS: These findings suggest that the IL-4Ralpha Ile75Val and Gln576Arg polymorphisms may be associated with work-related respiratory symptom development.

Squamous cell carcinoma of gallbladder is rare and its pathogenesis is unknown. A 63-year-old woman presented with right upper quadrant pain. Investigations revealed irregular and ill-defined heterogenous soft tissue mass in gallbladder fossa, which was infiltrated to the liver, pancreatic head, and duodenum on CT scan. Biopsy of liver and duodenum confirmed it as squamous cell carcinoma. Because the normal gallbladder does not have a squamous epithelium, squamous cell carcinoma of gallbladder has been the subject of interest in several publications. We report a case of squamous cell carcinoma of gallbladder.

Porcine pancreatic extracts (PPE), which are widely used as a digestive drug in Korea, are composed of alpha-amylase and lipase. Such enzymes are commonly described as occupational allergens. This is the first report of occupational rhinitis caused by PPE developing into occupational asthma in a hospital nurse. She showed strong positive response in the skin prick test (SPT) (5+, wheal ratio of allergen to histamine) and had a high serum-specific IgE level to PPE, but showed a negative response in the methacholine bronchial challenge test (MBT). She had been exposed to PPE intermittently with intermittent medications for rhinitis. Two years later, she presented with rhinitis and additional asthmatic symptoms. In contrast to her first visit, she showed a positive response in the MBT, and developed bronchoconstriction in the PPE-bronchial provocation test (BPT). These findings suggest that inhalation of PPE powder can induce IgE-mediated occupational rhinitis in a hospital setting, which will develop into occupational asthma if avoidance is not complete.
