Foreign body (FB) ingestion of children is a common pediatric emergency requiring medical attention. Pediatric emergency physicians and gastroenterologists often encounter nervous and distressed situations, because of children presenting with this condition in the common clinical practice. When determining the appropriate timing and indications for intervention, physicians should consider multiple patient- and FB-related factors. The utilization of a flexible endoscopy is considered safe and effective to use in these cases, with a high success rate, for the effective extraction of FBs from the gastrointestinal tract of a child. Additionally, a Foley catheter and a magnet-attached Levin tube have been used for decades in the case of FB removal. Although their use has decreased significantly in recent times, these instruments continue to be used for several indications. Using a Foley catheter for this purpose does not require special training and does not necessarily require sedation of the patient or fluoroscopy, which serve as advantages of utilizing this method for foreign object retrieval. An ingested magnet or iron-containing FB can be retrieved using a magnet-attached tube, and can be effective to retrieve an object from any section of the upper gastrointestinal tract that can be reached. Simple and inexpensive devices such as Foley catheters and magnetattached tubes can be used in emergencies such as with the esophageal impaction of disk batteries if endoscopy cannot be performed immediately (e.g., in rural areas and/or in patients presenting at midnight in a facility, especially in those without access to endoscopes or emergency services, or in any situation that warrants urgent removal of a foreign object).

The authors have been performed a statistical survey for 228 cases with foreign bodies in the food and air passages who had visited the department of Otolaryngology, National Medical Center and removed endoscopically during the period of last 10 years from 1966 to 1975. The following results were obtained: 1. The total numbers of foreign bodies in the food and the air passages were 228 cases, and among of them 181 cases were foreign bodies in the food passage and 47 cases were foreign bodies in the air passage. The ratio between the food and the air passages was about 3.7 : 1. 2. The prevalent foreign bodies in the esophagus were coin, meat and food particles and bone in order of frequency. In air passage, bean and peanut were most prevalent foreign bodies and the next were metalic substances, fish bone in order of frequency. 3. In the age incidence, 65.4% of the esophageal foreign bodies and 67.6% of foreign bodies in the air passage were under 5 years of age especially coin, 92.9%. 4. In sex distribution, 99 cases were female, and the ratio between male and female was 1.3:1. There was no significant difference between male and female in the foreign bodies of the esophagus but the foreign bodies in the air passage were more prevalent in male as the ratio of 2.1:1. 5. The most prevalent site of lodgement in esophagus was first physiologic narrowing of the esophagus as the count of 83.8%. In foreign bodies of the air passage, bronchial foreign bodies were most frequent. And bronchial foreign bodies were more frequent in the right side as the ratio of 3.7:1. 6. In duration of lodgement, 56.0% of foreign bodies of the food passage were removed within 24 hours and almost of them were removed within 5 days. In foreign bodies in the air passage, only 32.4% were removed within 24 hours but 29.7% were removed within more than 1 week in the air passage. 7. Under the esophagoscope, granulation tissue were noted in the 5 cases of the foreign bodies in the esophagus due to foreign bodies. In foreign bodies of the air passage, complication were encountered in the 4 cases and also removed surgically and among of them, 2 patients were expired due to complications during post operative course.

From April, 1981, through March, 1989, 30 patients had received valve replacements and 1 patient had received foreign body removal for infective endocarditis at Seoul National University Hospital. There were 22 male and 9 female patients, ranged in age from 22 to 59 [mean 34.9] years. Twenty-three had native valve endocarditis, 7 had prosthetic valve endocarditis and 1 had infected transvenous permanent pacemaker electrode in right heart. Twenty-four required operation during active phase of disease and 7 during inactive phase. The infecting organism was Streptococcus in 10 patients, Staphylococcus in 5 patients, both Staphylococcus and Streptococcus in 1 patient, E. coli in 2 patients, and Candida in 1 patient. Indications for Surgery were congestive heart failure in 20, systemic emboli in 5, combination of both in 3, congestive heart failure with uncontrolled sepsis in 2, and complete heart block in 1 patient. Hospital mortality was 9.7% [3/31], and all were the patients who received emergency operation. There were 2 late mortality [7.7 %] due to acute myocardial infarction and recurrent endocarditis. This report suggests that the surgical treatment can be achieved with acceptable low mortality and morbidity in medically intractable congestive heart failure, emboli and sepsis.

PURPOSE. The aim of this study was to determine the frequency of significant panoramic radiographic findings and eventual treatment requirements before conventional or implant supported prosthetic treatment in asymptomatic edentulous patients. MATERIALS AND METHODS. A total of 743 asymptomatic edentulous patients were retrospectively evaluated using a digital panoramic system. We analyzed the radiographic findings, including impacted teeth, retained root fragments, foreign bodies, severe atrophy of the posterior maxillary alveolar bone, mucous retention cysts, soft tissue calcifications and radiopaque-radiolucent conditions. RESULTS. Four-hundred-eighty-seven (65.6%) patients had no radiographic finding. A total of 331 radiographic findings were detected in 256 (34%) patients. In 52.9% (n=175) of these conditions, surgical treatment was required before application of implant-supported fixed prosthesis. However, before application of conventional removable prosthesis surgical treatment was required for 6% (n=20) of these conditions. CONCLUSION. The edentulous patients who will have implant placement for implant-supported fixed prosthesis can frequently require additional surgical procedures to eliminate pathological conditions.

Previous phylogenetic studies on human immunodeficiency virus type 1 (HIV-1) isolated from Korean patients suggest that the major subtype of Korean isolate is subtype B. In this subtype, some of the Korean isolates seem to be clustered exclusively of foreign isolates. Presence of this so-called “Korean clade” among Korean isolates is unique but needs verification since the number of Korean isolates used in previous studies was limited. This study aimed to identify the presence of the “Korean clade” by molecular phylogenetic analysis using all the Korean nef gene sequences registered in the NCBI GenBank (N=243) together with 32 reference strains and 77 foreign isolates. Extensive analysis of the nef gene nucleotide sequences by neighbor-joining method revealed the following. Most (83.1 ％) of the Korean isolates belonged to subtype B, and 81.2％ of subtype B were clustered together and excluded foreign isolates (bootstrap value=91.9％ ). Within Korean subtype B cluster, no characteristic subcluster formation was evident since the bootstrap values for the subcluster were very low. Due to limited information, the phylogenetic analysis failed to identify the epidemiological linkage among specific groups such as homosexuals and hemophiliacs within the Korean subtype B cluster. Detailed analysis and epidemiological information are needed to clarify the origin and significance of the Korean subtype B cluster.

The detection of foreign bodies in the upper-aerodigestive tract is a fairly frequent event and can occur in various areas and for various reasons. In rare cases, foreign bodies can simulate a neoplasia. We evaluated similar cases during emergency regimen with an oral cavity mucosal lesion, causing lockjaw, sore throat, dysphagia, and swelling of the submandibular and laterocervical region. Physical examination revealed an extensive mucosal ulceration in the floor of the mouth and the lateral surface of the tongue, comparable to oral cancer. During a second, more accurate assessment, a partially deteriorated iron supplement tablet was found embedded in a mucosal pocket. After removing the tablet, gradual normalization of the tissue was observed without any sequelae. This is one of the many reasons why it is advisable and useful in cases of oral lesions to collect a detailed medical history and to perform an accurate clinical evaluation, including inspection and palpation of the lesion, before proceeding to further diagnostic assessments, especially in elderly patients taking many medications. However unlikely, it is possible that difficulty in swallowing pills or tablets could generate tumorlike lesions.

Objectives: In the Republic of Korea (ROK), the notified incidence of tuberculosis in foreign-born individuals (NITFBI) has increased recently, as has the rate of multidrug-resistant (MDR) and rifampicin-resistant (RR) tuberculosis in foreigners staying in the ROK. As Jeju Province in ROK has a no-visa entry policy, control programs for NITFBI should be consolidated. The aim was to evaluate the status of NITFBI, with a focus on the distribution of MDR/RR tuberculosis by nationality. Methods: Data on tuberculosis incidence in individuals born in Jeju Province and in foreign-born individuals were extracted from the Korean Statistical Information Service of Statistics Korea, and the Infectious Disease Surveillance Web Statistics of the Korea Centers for Disease Control and Prevention, respectively. Results: Among all notified incident cases of tuberculosis, the proportion of NITFBI increased from 1.46% in 2011 to 6.84% in 2017. China- and Vietnam-born individuals accounted for the greatest proportion of the 95 cases of NITFBI. Seven cases of MDR/RR tuberculosis were found, all involving patients born in China. Conclusions: In Jeju Province, ROK, NITFBI might become more common in the near future. Countermeasures for controlling active tuberculosis in immigrants born in high-risk nations for tuberculosis should be prepared in Jeju Province, since it is a popular tourist destination.

Purpose: The purpose of this study is to analyze the deployment characteristics of korean and foreign mobile hospitals and to draw out the advantages and disadvantages based on the movement of patients. Methods: The arrangement and user movement lines of foreign mobile hospitals which were actually utilized, and the arrangements and user movement lines of korean mobile hospitals are compared and analyzed. Based on the results of the comparative analysis, we suggest the optimal placement of mobile hospital in Korea. Results: The recently developed Korean mobile hospitals have made many improvements. However, there is no practical use case for the mobile hospital in Korea, so it is necessary to establish the basis for the mobile hospital development site and the site access considerations. In addition, there is no detailed analysis of the movement of the administrators other than the medical staff, and it is considered that research on safe waste disposal is further needed. Implications: It is highly likely to be used as a basic data to find out the combination method of mobile hospitals that can efficiently deal with disasters through the arrangement and movement analysis of mobile hospitals in Korea and abroad.

The review of 68 patients, who were diagnosed as spontaneous pneumothorax during the period from Dec, 1991. to Jul, 1992. were performed thoracoscopy of 70 cases under local anesthesia with 1% lidocaine at the department of thoracic & cardiovascular surgery, HanYang University Hospital. Clinical data on distribution of Age & Sex, Location, Frequency of Reccurrence and other aspects of pneumothorax were summerized.37 cases were treated by thoracoscopic management and closed thoracostomy. As thoracoscopic management, Electrocauterization of bullae or blebs[37 cases], Endo-clip application [2 cases], Removal of foreign body[1 case] were performed. 31 cases were cured by open thoracotomy. The thoracotomy indications under thoracoscopic finding were followed as: 1. Severe pulmonary adhesion and destroyed lung parenchyme 2. multiple bullae or blebs on several areas 3. finding of pulmonary tuberculous caseous lesion 4. persistant air leakage after 7 days from thoracoscopic management Excision, wedge resection of bullae or blebs was performed in most cases [22 cases], 2 cases by median sternotomy and Segmentectomy of 7 cases were carried out depending on the pathologic change of lung.There was no operative mortality and Follow-up for all patients were showed good results.

In the course of treating approximately 740 patients with open heart surgery, we experienced 38 patients who underwent open heart surgery as the second operation after initial operation on heart at Seoul National University Hospital. Twenty four cases of congenital 14 acquired heart disease were found. There was 14 operative death of 38 patients, resulting in overall mortality 36.8 %; 8 death [33.3 %] in congenital group, 6 [42.9 %] in acquired group. Principal causes of death were lower cardiac output syndrome and congestive heart failure. Compared with foreign report, as this data shows still high overall mortality, this review suggests that second open heart surgery can be performed safely with reasonable operative mortality and satisfactory prognostic outlook in the near future.
