Aspirin(ASA) and NSAIDs can induce bronchoconstriction in 10~20% of adult asthmatics patients. Inhalation of lysine-ASA(L-ASA) has been described as an alternative method for diagnosis of ASA-sensitive asthma. To further understand the characterlstics of ASA-sensitive asthmas. we studied 38 asthmatic patients with ASA -sensitivity (36 intrinsic and 2 extrinsic asthma) proven by L-ASA bronchoprovocation test (BPT). Most were female (male to female ratio was 27:73). Twenty (53%) of them had no previous history of adverse reactions when exposed to ASA. Twenty nine (79%) had rhino-sinusitis symptoms. Early asthmatic response was observed in 16 (42%) patients, late only response in 16(42%), and dual response in 6(16%) patients. The threshold of L-ASA to provoke a positive response ranged from 11.2 to 180 mg/ml and most (68.3%) had a positive response after the inhalation of 180 mg/ml. Concurrent sensitivity to sulfite was noted in 14 (36%) patients, followed by sensitivity to tartrazine in one (3%) patient. None showed a positive response to sodium benzoate. After the avoidance from ASA/ NSAIDs with administration of anti-asthmatic medications, symptom and medication scores reduced in 26(87%) patients among 30 followed patients. They were classified into the improved group: four (13%) patients belonged to the not-improved group. There were no significant differences in clinical characteristics between the improved and not- improved group (p>0.05). In conclusion, L-ASA BPT could be considered as a useful method to diagnose ASA -sensitive asthma and be used to screen the causative agent for asthmatic patients with intrinsic type, especially in female patients with rhino-sinusitis and/or nasal polyp, even though they do not have arty history of adverse reactions. Cessation of exposure and proper treatment may allow to reduce symptom and medication scores.

Sialodochitis fibrinosa is a disease characterized by salivary duct obstruction. A 21-year-old male presented with a painful submandibular gland (SMG) swelling. Serum eosinophilia and Whartons’ duct dilatation with strong enhancement were observed on contrast CT. Core needle biopsy (CNB) for SMG parenchyma revealed lymphocytic infiltration between dilated intralobular ducts. In another case, a 39-year-old male complained of recurrent major salivary glands swelling for ten years with an itching sensation on the overlying skin of the salivary gland. Enhancement of both SMG parenchyma, dilatation of both Wharton’s ducts and elevated serum eosinophilia were observed on contrast CT study. CNB for SMG parenchyma revealed lymphocytic infiltration with many eosinophils around a markedly dilated interlobular duct. The recurrent SMG swelling in both cases were relieved by antihistamine medication, warranting suspicion that these cases might organ-specific eosinophilic disease. We dicuss these two cases with a literature review.

Continuous epidural analgesia has been used for decades to treat acute herpes zoster pain and to prevent postherpetic neuralgia. However, many technical problems can arise during chronic treatment with epidural medications. These complications include catheter dislodgement, infection, injection pain, leakage, and occlusion. Epidural catheter placement utilizing subcutaneous injection port implantation has gained widespread acceptance as a method to overcome such complications. The technique reduces the risk of infection, the most feared complication, compared to the use of a percutaneous epidural catheter. Herein, we present 2 cases in which the continuous thoracic epidural administration of opioids and local anesthetics through an implantable subcutaneous injection port for over 2 months successfully treated zoster-associated pain without any technique- or medication-related complications in patients with risk factors for epidural abscess.

BACKGROUND: The accidental swallowing of foreign body is a common problem in the children. Ingested foreign bodies may be managed by endoscopy, observation, or surgery. So we analyzed the methods of removal, type, location and complications of foreign bodies. MATERIALS AND METHODS: This report reviewed 37 cases of ingested foreign body in the gastrointestinal tract at the Department of Pediatrics, Yeungnam University Hospital between January 1997 and April 2001. RESULTS: The age ranged from 8 months to 8 years. The most prevalent age group was between 1 year and 2 years of age(19%). The male to female ratio was 2.1:1 with 25 male and 12 female patients. The type of foreign bodies were coins in 20 cases(54%), nail in 4 cases(11%), key in 4 cases(11%), pin in 2 cases(5.5%), necklace in 2 cases(5.5%) and others. The locations of foreign bodies were upper esophagus in 12 cases(32.5%), lower esophagus in 4 cases(10.8%), stomach in 16 cases(43.2%), small bowel in 5 cases(13.5%). 4. Presenting symptoms were variable with asymptomatic (59. 4%) , vomiting (19. 0%) , epigastric pain (8.1%), dysphagia (5. 4%) and others. The methods for removal of foreign bodies included 20 cases of endoscopic removal(54.0%), 3 cases of spontaneous removal(8.1%) and there was no surgical removal. 14 cases(37.9%) did not confirmed removal of foreign body because of no revisit of our hospital. Endoscopic finding of patients were normal(15 cases), ulceration(2 cases), erosion(1 case), inflammation(l case), mucosal scratch(l case). CONCLUSION: It appears that the endoscopic approach is the preferable method for the removal of upper gastrointestinal foreign bodies in the children.

Background and Objectives: The objectives of this study were to investigate the aspiration patterns in patients with T3 and T4 oral and oropharyngeal cancers after free flap reconstruction following primary tumor resection and determine the effect of tongue base resection on aspiration patterns in these patients.Subjects and Method The aspiration pattern was evaluated via fiberoptic endoscopic evaluation of swallowing and classified into three groups based on the timing of aspiration in relation to the swallowing process. More than two types of aspiration patterns observed simultaneously in a patient suggested combined aspiration pattern. Results: The major pattern of aspiration in 31 patients with oral cavity cancer was aspiration after swallowing in the group with base of tongue (BOT) preserved (83.3%, 10/12) and combined aspiration in the group with BOT resection (63.2%, 12/19), showing a significant difference in aspiration pattern between the two groups (p<0.001). In oropharyngeal malignancies, the major pattern of aspiration was aspiration after swallowing in both BOT-preserving (87.5%, 21/24) and BOT-resecting groups (75.0%, 9/12), showing a significant difference in aspiration pattern between the two groups (p=0.031). Conclusion The most common pattern observed in the advanced T stage tongue cancer patients after glossectomy was aspiration after swallowing. Resection of BOT greater than 25% in the tongue and oropharyngeal cancer was a significant factor causing the combined type of aspiration.

Dysphagia is difficulty of effect movement of the bolus from the mouth to the stomach. From and anatomical standpoints, dysphagia is typically classified as oropharyngeal dysphagia (OPD) and esophageal dysphagia (ED). In general, OPD is more highly prevalent condition compared with ED, and associated with severe complications such as malnutrition, dehydration and aspiration pneumonia. These complications are fatal especially in the elderly. Therefore, for preventing severe complications, appropriate and prompt management should be provided to dysphagia patients. However, the decrease of swallowing function is considered as a part of natural aging process. This condition is called as presbyphagia. Although Presbyphagia refers to characteristic changes in the process of swallowing of healthy elderly, it can be a risk factor of dysphagia. With this in mind, for avoiding overdiagnosis or underdiagnosis of dysphagia, we should distinguish among presbyphagia, dysphagia and other related diagnoses. For this reason, understanding about physiology of normal swallowing and natural changes of swallows by aging are essential for physicians. Hence, this review discusses the normal swallow, senile changes of swallow, and dysphagia especially in OPD.

BACKGROUND AND OBJECTIVES: Irritable bowel syndrome (IBS) is prevalent in the general population, but there are few reports on bowel habits and IBS in high school students in Korea. This study aims to describe the prevalence of IBS in high school students in Korea and to investigate the influence of lifestyle factors including dietary habits, on the IBS. This study also investigates relationship between anxiety, depression and IBSprevalence. SUBJECTS AND METHODS: This study is a cross-sectional study on 1,018 students (451 males and 567 females) form freshman to senior of a high schools in Seoul. All students were requested to fill in a self-reported questionnaire. IBS was diagnosed based on the Rome II criteria. Those having past medical history of organic gastrointestinal disorders and any one of the 'alarm factors'(e.g. continuous hematochezia, weight loss, or anemic symptom) were excluded from the IBS group. For the evaluation of risk factors on the IBS, we surveyed dietary habit, health behavior, past medical history, the Hollingshed index for the measurement of socioeconomic status, Beck's Anxiety Inventory for the anxiety, and the Children's Depression Inventory for the depression. RESULTS: The prevalence of IBS was 19.1%. Family history of abdominal discomfort (odds ratio 2.07, 95% 1.46-2.92) and having night snack (odds ratio 1.46, 95% CI 1.09-1.94) were significantly different between the IBS group and non-IBS group. There was a linear trend towards the higher prevalence of IBS with fewer hours of exercise (odds ratio 0.99, 95% CI 0.95-1.04). Menstruation, stress, and irregular eating were the significant provocation factors of IBS. Anxiety and depression was not significantly higher in in the IBS group. CONCLUSIONS: Prevalence of the IBS in high school students from this study was higher compared with those reported in college students in Korea. This study shows that family history, dietary factors, lifestyle, and grade were significantly related to IBS. From our study, we found that there are multifaceted health aspects required to reduce symptoms, such as dietary education and encouragement to change lifestyle for controlling stress.

The coronavirus disease 2019 (COVID-19) pandemic has taken a toll on human lives and health systems worldwide and is still affecting all medical practices years later. In particular, much medical staff had to sacrifice in areas where the medical system was overloaded in the early stages of the outbreak and the resulting shortage of medical resources. In the future, another pandemic disease seems to emerge, which should threaten otolaryngologists inevitably. It is necessary to understand viral aerosolization and practice recommendations for COVID-19. These can guarantee the most effective treatment for the patients during the pandemic and protect the safety of our medical staff and patients.
