A major concern in pediatric dentistry is maximizing risk management through optimal monitoring of respiratory function during sedation techniques, and Pulse Oximeter is one of the most popular devices for these purpose. Pulse Oximeter is non-invasive device for detecting the sensitive fraction between the saturated & desaturated hemoglobin. Several Studies proved that there is no significant difference between the $SpO_2$ and $SaO_2$. In this article, We examined three Pulse Oximeter $(3300MX^{(R)},\;OX90^{(R)},\;BPM200^{(R)})$. The Pulse Oximeter using shorter pulse beat averaging showed more sensitive reaction to the statue of the patient and lower saturation data. We compared pair of Pulse Oximeter applied to one patient at one time. and $BPM200^{(R)}$(using shorter pulse beat averaging) showed statistically low saturation.

Purpose: It was necessary for developing a neonatal classification system based on nursing needs and direct care time. This study was, thus, aimed at identifying nursing activities and measuring the standard nursing practice time for developing a neonatal patient classification system in Neonatal Intensive Care Unit (NICU). Methods: The study was taken place in 8 general hospitals located in Seoul and Kyungi province, South Korea from Dec, 2009 to Jan, 2010. By using 'the modified Workload Management System for critical care Nurses' (WMSN), nursing categories, activities, standard time, and task frequencies were measured with direct observation. The data were analyzed by using descriptive statistics. Results: Neonatal nursing activities were categorized into 8 areas: vital signs (manual), monitoring, activity of daily living (ADL), feeding, medication, treatment and procedure, respiratory therapy, and education-emotional support. The most frequent and time-consuming area was an ADL, unlike that of adult patients. Conclusion: The findings of the study provide a foundation for developing a neonatal patient classification system in NICU. Further research is warranted to verify the reliability and validity of the instrument.

Pierre Robin sequence as a symptom triad of micrognathia, glossoptosis, and cleft palate results in upper airway obstruction and feeding problems. If mild, it is often managed in the prone position. When positional treatment fails, however, surgical intervention such as tongue-lip adhesion, tracheostomy, and mandibular distraction osteogenesis is mandatory to relieve airway obstruction. There has been growing interest in the application of distraction osteogenesis for the management of craniofacial abnormalities. The mandibular distraction osteogenesis to newborns may prevent the airway obstruction, decrease the potential tracheostomy, and reduce the likehood of orthognathic surgery after growth. We experienced an infant with Pierre Robin sequence who showed mandibular hypoplasia, glossoptosis, incomplete cleft palate, intermittent cyanos is, depression of the chest, and respiratory difficulty associated with airway obstruction. We treated the airway obstruction by tongue-lip adhesion at 2 weeks of age, and treated the mandibular retrognathism and depression of the chest byusing internal mandibular distraction osteogenesis at 7 month of age. The mandible moved forwardly, the upper airway space was enlarged, and the antero-posterior distance of the mandible was elongated after the mandibular distraction. Mandibular distraction osteogenesis may be a promising technique to avoid the need of tracheostomy and orthognathic surgery, and to correct airway obstruction in infants with congenital craniofacial malformation.
Tracheostomy and endotracheal intubation are often performed in patients with acute and chronic respiratory failure. Recently, the incidence of iatrogenic tracheal stenosis has increased. Tracheal resection and end-to-end anastomosis would be one of the most physiologic treatment options for severe tracheal stenosis. Also, this treatment can be applied to the management of trachea invaded by thyroid cancer and tracheal neoplasm. The authors aimed to analyze the outcomes of end-to-end anastomosis of trachea following segmental resection in tracheal stenosis and tracheal invasion of cancer that we have recently experienced. Materials and methods Authors retrospectively studied 19 cases treated by tracheal resection with end-to-end anastomosis between Feburuary 1996 and January 2003. 12 patients had tracheal stenosis, 6 patients had tracheal invasion by thryroid cancer and 1 patient had tracheal cancer. We analyzed the direct causes of tracheal stenosis, preoperative vocal cord function, operation technique, early and delayed postoperative complications, and the outcome of end-to-end anastomois. Result Decannulation without significant aspiration was achieved in 16 cases($89.5\%$). A 27 year-old man could not be decannulated because of restenosis. A 62 year-old woman could not be decannulated because of bilateral vocal cord palsy. Conclusion End-to-end anastomosis is a safe and effective surgical method for tracheal stenosis. Case selection for end-to-end anastomosis and preservation of recurrent laryngeal nerve during operation is very important.
Background: Many factors including drugs, dietary supplements, and food intake can affect the development and organ formation of fetuses. Because of this, subject tends to avoid consuming things like coffee, alcohol, or cigarettes due to the risks they pose during pregnancy. Therefore, analysis of drugs and favorite food consumption is needed and important to ensure safe health management for subject. Purpose: This study was conducted domestically to analyze these factors in South Korea. Method: The survey was conducted from pregnancy-related online communities for six days and the survey results were received via email for analysis. Result: A total of 127 subjects answered the questionnaire via email; the characteristics of subjects are widely varied in their ages, education levels, job statuses, and residences. The questionnaire included the intake of dietary supplements during pregnancy including vitamins and the result showed that the subjects took 2.23 different kinds of supplements on average. In order of highest frequency, 101 subjects took multivitamins; 79 subjects took an iron supplement; 30 subjects took analgesics; 20 subjects took prescribed antipyretic and medication for upper respiratory diseases; 12 subjects took antibiotics; 7 subjects took antiemetics. Their compliances were different in each medication categories. Only 8% of subjects answered that they had asked a pharmacist for medication information during pregnancy. In addition, 78% of subjects answered that they never counseled with anyone about pregnancy related medication use. Conclusion: In conclusion, many subjects took medication including dietary supplements. The role of pharmacists should be actively developed to improve subject care such as education about subject's medication uses and their food consumption behavior.
Using a visual analogue scale, we compare the effect of patient-controlled analgesia and conventional intramuscular opioid regimen in 68 patients undergoing lower abdominal or gynecological surgery. We also recorded the incidence of side effects. We checked visual analogue scale 4 hours interval for 30 cases managed by patient-controlled analgesia and 38 cases of conventional intramuscular opioid group managed by obstetrician. We maintained fentanyl $0.33{\mu}g/kg/hr$ and set self administrable bolus dose $5.0{\mu}g$(lockout interval: 15 min) in patient-controlled analgesia group. Conventional intramuscular bolus injection group were administered meperidine 50 mg for 4 hour interval. Mean visual analogue scale scores obtained by patient-controlled analgesia group and intramuscular bolus injection group were $2.49{\pm}0.67$ and $4.53{\pm}1.28$(p<0.05). Side effects such as; no significant incidence of respiratory depression, urinary retention, postural hypotension, nausea, vomiting and pruritus were developed by either group. These results suggest that patient-controlled analgesia was more effective method compared with conventional intraumuscular opioid injection regimen for post-operative pain management.

In modern society, we are living indoor at 80 - 90 % or more of the day, therefore most people are exposed to unconscious indoor air pollutants by various causes. When mother and infant, whose level of immunity are weak, are exposed to polluted indoor air, respiratory diseases and atopy can occur by the growth of bacteria. Therefore, appropriate indoor air quality management is important especially at nursery, elementary school and postpartum clinic etc. In this study, we compared the characteristics of the indoor air qualities of primary school facilities and infant facilities. In this study, seasonal effects were investigated. Also the effects of individual activity area were studied for indoor air quality. During summer season(May-August), the air qualities of each 16 elementary school and nursery school were investigated. During winter season(October-december), the air qualities of each 10 elementary school and nursery school were investigated. As a result, during winter season in 10 of 16 nursery school, $CO_2$ concentration exceeded regulation level of 1000 ppm. This resulted from the operation of heating system and poor ventilation. Also the air quality of all parameters during winter season were worse than during summer, maybe due to poor ventilation. Except HCHO, the concentrations of other parameters were higher in nursery school. This seems to result from relatively low individual activity area of nursery school than elementary school. From this research, more strong regulation for ventilation and installation of air purifier should be implemented.
A clinical investigation was reported on 17 cases of spontaneous pneumothorax requiring surgical mana-gement. Males outnumbered females 15:2. Determination of the etiology in this series showed that the majority were pulmonary tuberculosis and paragonimiasis. Several others had pneumonia, lung abscess, cyst and blebs. It is of particular interest that the acute inflammation of respiratory system was younger age group, pulmonary tuberculosis & paragonimiasis were between 2 nd and 3 rd decades, and lung abscess, cyst, blebs were above 4 th decade. Pulmonary tuberculosis was far advanced bilateral and active. The ratio of right to left side was 13:6 and both side involved in 2 cases. In about half cases of patients, above 50%-collapsed lung associated with mediastinal shifting developed. The complications were pleural effusion and bronchopleural fistula. The former was 13 cases [76.4%] in which 3 cases combined with mixed infection, and latter was 5 cases. As the management, 11 cases were subjected to intercostal or rib resection drainage with continuous suc-tion. Among 11 drainage cases, 8 cases were successful in acute stage and 3 cases failed in chronic stage. This faiure was due to interference with re-expansion of collapsed lung for peel formation and broncho-pleural fistula. The open thoractomy was applied in 9 cases, among which primary operation were 5 cases and drainage failure were 4 cases. Among 11 cases subjected to the open thoracotomy, wedged resection was performed in 3 cases including paragonimiatic cyst, and pneumonectomy in 1 case-tuberculosis, and decortication only was performed in 2 cases in paragonimiasis. Decortication & lung resection was carried out in 2 patients among which ruptured lung abscess 1 case and ruptured multiple blebs 1 case. There was no case of death but prognosis of the tuberculosis may be poor because of far advanced bilateral and active pulmonary tuberculosis.
Myasthenia gravis is a neuromuscular transmission disorder characterized by fatigue and weakness of voluntary muscles. Although the pathogenesis is known as reduction of available acetylcholine receptors at neuromuscular junctions by autoimmune attack, the thymic role in myasthenia gravis is still unclear and under investigation. But thymectomy in the management of myasthenia gravis has become increasingly important since the first successful operation with remission of symptoms in 1939 by Blalock. From January 1983 to June 1985, authors performed 17 thymectomies for patients with myasthenia gravis. Among them, 12 patients were free from thymoma [Croup A] and 5 were coupled with thymoma [Group B]. The results were as follows: 1] Sex distribution was 11 females and 6 males. Mean age of the patients was 32.2 year old. Sex and age distribution by the Group A and B are shown Table 1. 2] Clinical manifestations of ocular symptoms were seen in 5 patients [88.2%], extremity weakness in 13 patients, bulbar weakness in 12 patients and dyspnea in 6 patients. According to the Osserman`s classification, 5 patients were in group IIA, 6 in IIB and 6 in IIC. 3] Pre-operatively, all patients were positive response to the anti-cholinesterase test and 12 patients [92.3%] revealed positive findings in electromyography [EMC] which was done in 13 patients. 4] The postoperative complications were respiratory distress in 3 patients, myasthenic crisis in 2 patients and wound disruption in one patients. 5] Pathologic examination of the thymus showed hyperplasia in 10 patients [90%] and thymoma in 5 patients, of which 4 were mixed type with invasion to the adjacent tissues and one lymphocytic type without invasion. Normal thymus was noticed in only 2 patients. 6] In postoperative evaluations, among the 12 patients c free from thymoma [Group A], complete remission of symptoms was noticed in 3 patients and improvement in 7 patients. But among the 5 patients coupled with thymoma [Group B], only one patients showed improvement [Table 8]. Therefore, remission and clinical improvement were noticed in 11 patients [64.7%] of the all and complete remission was noticed in 3 patients [17.6%].

Purpose: Radiocontrast media are widely used in medical imaging to improve diagnostic accuracy. However, studies on the adverse reactions of radiocontrast media in children are limited. We aimed to describe the characteristics of adverse reactions to radiocontrast media among children who had a computed tomography scan or magnetic resonance imaging in a tertiary university hospital. Methods: We retrospectively collected data on adverse reactions to radiocontrast media by the reporting system of a tertiary university hospital. We selected data from children under the age of 19 from July 2011 to December 2017 and analyzed their characteristics. We focused mainly on the characteristics of the index case which is defined by the first adverse event of each subject. Results: During the period, a total of 88,050 radiocontrast media-enhanced imaging studies were performed and 184 cases of adverse reactions were reported. A total of 71 were identified as index cases. Forty-nine (69.0%) were male and the mean age was $12.7{\pm}3.2$ years. The incidence of radiocontrast media-related adverse reactions was 0.09% and severe reactions were 0.002%. The most common clinical feature was skin manifestations (54.9%), followed by gastrointestinal symptoms (40.8%) and neuropsychiatric symptoms (7.4%). Conclusion: Adverse reactions to radiocontrast media rarely occur in children and the incidence of severe reactions is low. Most reactions are mild and are related to the skin and gastrointestinal system. This report would provide good evidence for establishing a management strategy in children scheduled for imaging studies using radiocontrast media.
