Purpose: Recent studies of food allergy (FA) at all ages are scanty in Korea. We performed this study to better understand severityrelated and age-stratified causes of FA from infants to older adults in a single tertiary hospital in Korea. Methods: A retrospective medical record review was performed on patients of all ages diagnosed with immediate-type FA between March 2008 and February 2018 in Ajou University Hospital. Results: A total of 4,680 cases of FA among 2,733 patients were reported. The distribution of onset ages of the first FA symptom was as follows: 45.3% below 2 years, 16.2% at 2-6 years, 5.5% at 7-12 years, 4.0% at 13-18 years, 16.9% at 19-40 years, 10.4% at 41-65 years, and 1.8% above 65 years of age. The major 10 causative foods were hen's eggs (17.2%), cow's milk (16.7%), wheat (8.6%), crustaceans (8.5%), fish (4.6%), walnuts (4.4%), pork (3.2%), peanuts (3.2%), shellfish (3.0%), and peach (2.2%). The culprits ranked from the 11th to the 20th were as follows: soybean, apple, chicken, buckwheat, beef, kiwi, almonds, perilla seeds, tomato, and squid. The top 3 causative foods in children were hen's eggs, cow's milk, and wheat, while those in adults were crustaceans, wheat, and fish. Food-induced anaphylaxis was reported in 29.2% of all cases, with cow's milk, hen's eggs, wheat, crustaceans, fish, walnuts, pork, shellfish, buckwheat, and peanuts being the major 10 causes. Conclusion: This study could provide a better understanding of the detailed ranks of the causes of FA according to severity and age in Korea.

The labio-palatal location of the implant in the maxillary anterior region is one of the important factors affecting the aesthetics of the implant prosthesis. However, the thin labial bone of maxilla could be absorbed in significant amounts after extraction of the teeth, which makes the implant be placed on the palatal side rather than the ideal location. In fact, in the cases of maxillary central incisor loss, UCLA was used for prosthetic restoration of palatally placed implant. In addition, with multidisciplinary treatment, GBR (Guided Bone Regeneration) was performed for compensating the absorbed alveolar bone and adjacent anterior tooth were aligned. Definitive restoration was performed after confirming aesthetic recovery of the gingiva with sufficient provisional restoration period. There were satisfactory results of functional and esthetic recovery of tooth loss through implant prosthesis.

This case report describes a patient with olivopontocerebellar atrophy accompanied by sleep disorder and gait disturbance whose condition was improved by treatment with Korean medicine. The 61-year-old woman, who was diagnosed with olivopontocerebellar atrophy (Multiple Systemic Atrophy-Cerebellum), was admitted to hospital twice and treated with Korean medicine (acupuncture and herbal medicine) and rehabilitation. The Korean medicine was Gwibiondam-tang-gami and Jaeumgeonbi-tang-gami. Clinical symptoms were assessed by the Modified Bathel index, functional independent measurement, Berg balance scale, and Unified Multiple System Atrophy rating scale. A brain MRI at the one-year follow up after onset showed similar progress but clinical symptoms were improved after treatment, and the evaluation index score increased.Multiple system atrophy, a type of degenerative neurological disease, has no targeted treatment. In this situation, although this report describes a single case, Korean medicine treatment could provide a meaningful improvement in the sleep disturbance and gait disorder symptoms of patients with olivopontocerebellar atrophy.
