Purpose: An impacted tooth is defined as a tooth that shows delayed eruption and is expected to erupt incompletely by clinical and radiograph examination despite it reaching its expected time of eruption. The aims of this study were to investigate the clinical and radiological characteristics and treatment duration and method of impacted teeth in Korean patients. Materials and Methods: For this study we used clinical records, study models, panoramic radiographs and intraoral photographs of patients who attended Gachon University Gil Hospital Orthodontic Department between 2005 and 2008. There were 164 patients with a total number of 202 impacted teeth. Results: Male patients shows a little more prevalence than female patients (1.13:1). The under 12 age group had the highest prevalence of tooth impaction, and the over 19 age group showed the least prevalence of tooth impaction. The ratio of tooth impaction between the left to right ratio was 1.73:1 and maxilla and mandible was 1.84:1. The impacted teeth were most commonly positioned buccally (76 cases, 41.5%). Full nap closure technique (108 cases, 81.2%)was most frequently used for attachment of surgical traction hooks. Maxillary canine impaction was most commonly encountered both in male and female patients. The mean treatment period was 12.2 months and the success rate of treatment was 90.3%. The canine tooth shows the longest treatment time and highest failure rate. The ankylosis was the major cause of failure. Conclusion: Impacted teeth most commonly show in left side maxilla in the under 12 age group. And it is most commonly positioned buccally. The mean treatment period was 12.2 months, and the success rate of treatment was 90.3%.

Purpose: The interest in the personal mobility started to grow and as the interest increases, there are growing concerns about the safety of it. The purpose of the study is to look at the types and dynamics of patients injured by the personal mobilities. Methods: This was a retrospective 2-year observational study, from January 2016 to December 2017, on the patients who visited the emergency center and the trauma center, with an injury related to driving the personal mobility. Cases of the personal mobility-related accident were collected based on electronic medical records and hospital emergency department-based injury in-depth surveillance data. Results: A total of 65 patients visited the emergency center and the trauma center, during this study period. Six patients of 50 adults admitted the alcohol consumption (12%) and two adult patients wore the helmet as the protection gear (3.1%). The number of the patients in 2017 rises three times more than the number of patients in 2016 (51 vs. 14). Injuries to the head and neck region (67.7%) was the most common, followed by the upper extremity (46.2%). Eleven patients (16.9%) were admitted to the hospital, of whom three were admitted to the intensive care unit due to intracranial hemorrhage. Nine patients underwent surgery. Conclusions: The use of the personal mobility will continue to grow and the accidents, caused by the vehicle, will increase along with it. The study showed the damage is worse than expected. Personal mobility currently has a limited safety laws and the riders are not yet fully aware of its danger. The improvement of the regulation of the personal mobility, safety education is needed.

Telehealth is widely tested in the U.S.A and other developed countries. This system is expected to solve rural health problems reducing professional isolation. Some demonstration projects showed that the system can provide quality care in reasonable prices to rural residents. However, few study has been done on whether telehealth system can attract physicians by reducing professional isolation. The system is not available to most of the rural hospitals because the price for the equipment and telephone charges are not low enough. It is promising that the system cost and telephone charges are decreasing gradually. As time passes, rural hospitals will be more viable for the system. Satisfaction of the physicians and patients is a key factor for the implementation of the system. The physicians need to understand more about telecommunication and computer systems. After physicians are well-versed about the system, we can expect wide use of telehealth in rural areas. Effort for the confidentiality and standardization should be devoted to assure patient's privacy and compatibility of patient records and exam results. In Korea, two projects are being operated in Uljin and Kurye. A study evaluated the economic efficiency of the projects suggesting that increase of the number of patients up to three times of current number or decrease in hardware costs and telecommunication charges into two thirds of the current costs. The hardware and telecommunication charges are decreasing. Another area telehealth system can be applied is psychiatric accommodation facilities. Establishment of telehealth in the psychiatric facilities will increase the access of psychiatric care for patients and is expected to be economically efficient.

Although the number of foreign patients visiting Korea for medical treatments or plastic surgery is rapidly increasing, countermeasures against unforeseen medical disputes involving foreign patients are adequate. To date, the record shows that most foreign patients have visited doctors at the departments of family medicine, internal medicine, dermatology (incl. plastic surgery), and healthcare centers, which, fortunately, indicates that there are not many severe, high risk patients. However, if the current growth rate continues to rise and the number of foreign patients visiting each department continues to grow, more diverse medical practices will be likely to take place in the future, and consequently, it is expected that the possibilities of medical malpractice and the costs of dispute resolution will also rise dramatically. When a medical dispute occurs, in general, a lawsuit is ultimately settled by the court. However, since this can damage the creditworthiness of medical institutions and also incur significant litigation costs, which is a typical characteristic of a medical lawsuit, medical professionals or institutions will be heavily burdened. Furthermore, an adequate policy or countermeasure against a medical dispute with a foreign patient has not yet been established, and it would be difficult to resolve a dispute by finding the middle ground, due to relative standards and policies between countries. Now, we need to improve the existing policies and prepare for countermeasures that will allow us to precisely predict the nature of such disputes, which have been increasing, and resolve them peacefully. Based on such knowledge, this study aims to establish countermeasures against medical disputes with foreign patients, and examine ways to promptly and reasonably resolve them at an early stage.

Background: The incidence of rectal cancer is increasing in younger age groups. Limited data is available regarding survival outcome in younger patients with conflicting results from western world. The goal of this study was to determine survival in patients with rectal cancer <30 years of age and compare it with their older counterparts in the Pakistani population. Materials and Methods: A retrospective chart review of patients operated for rectal adenocarcinoma between January 2005 and December 2010 was performed. Patients were divided into two groups, Group 1 aged ${\leq}30years$ and Group 2 aged >30years. Patient characteristics, surgical procedure, histopathological details and number of loco-regional and distant failures were compared. Expected 5 year survival was calculated using Kaplan Meier curves and significance was determined using the Log rank test. Results: There were 38 patients in group 1 and 144 in group 2. A significantly high number of younger patients presented with poorly differentiated histology (44.7% vs 9.7%) (p=0.0001) and advanced pathological stage (63.1% vs 38.1%) (p=0.04). Predicted overall 5 year survival was 38% versus 57% in groups I and II, respectively (p=0.05). Disease free survival was 37% versus 52% and was significantly different (p=0.007). Conclusions: Early onset rectal cancer is associated with poor pathological features and a worse outcome in Pakistani population.

Purpose: This study aimed to examine the effects of extended family visiting hours in the intensive care unit (ICU). Methods: The subjects were 168 ICU patients and their family members. Two 30-minute visits a day were allowed to the control group according to current policy, while four 30-minute visits a day were allowed to the experimental group. Patients' state anxiety was measured at the first day of ICU admission, and on the third day of ICU admission patients' anxiety and family satisfaction were measured. For the infection rate, comparison was made between the experimental and control data-collecting periods. Results: The patients' state anxiety significantly decreased in the experimental group. Family satisfaction of experimental group was significantly higher than that of control group. There was no significant difference in the infection rate. Nurses positively evaluated extension of visiting hours because it could stabilize patients, reduce the number of arrangements for additional visits, and help establish trust relationship with families. Conclusion: Extended family visiting hours in the ICU reduced patients' anxiety and improved family satisfaction but had no effect on the infection rate. Extended family visiting hours in the ICU is expected to improve the quality of critical care.

Objectives : This study investigates the association between weather conditions and the rate of no-shows at an academic medical center. Methods : Electronic data regarding medical appointments atover the course ofone academic year (2016.03~2017.02) were used for analysis. Characteristics of weather conditions and the daily number of no-shows were compared by Chi-square test. A logistic regression was run to determine if certain aspects of weather affected the rate of no-shows. Results : The results reveal an overall no-show rate of 6.8% that appears to vary in accordance with specific weather conditions. Lower average temperatures, in particular, corresponded with a higher rate of no-show patients. This may indicate that o-show rates in autumn and winter can be expected to exceed those during spring. Conclusions : This study investigates the association between no-show patients and weather conditions, and offers suggestions for augmenting this loss. One recommendation is to begin conducting investigations nationwide in order to provide more useful information.

The aim of this study was to analyze various data of 120 non-submerged ITI implants placed in 64 korean adults. The data were retrieved from patients' charts and registered in the computer and coded for a statistical analysis. The results revealed that the most common type of edentulism was a distal extension case, and the largest number of implants were placed in the mandibular first molar position. Implants were placed more frequently in mandibular, posterior position than maxillary, anterior position, respectively. With respect to the implant diameter and length, an implant with 4.1mm in diameter and more than 10mm in length was the most common. Since a molar position was the most prevalent position for implant placement in korean patients, clinicians should be careful about implant diameter which can resist a strong occlusal force expected in the molar position. In addition, the distance to the mandibular canal and the floor of maxillary sinus should be considered to avoid possible damages, such as nerve injury and sinus perforation in selecting a proper implant length.

Liver transplantation is widely accepted as an effective therapeutic modality for a variety of irreversible acute and chronic liver diseases for which no satisfactory therapy is available. Following the first unsuccessful efforts at human liver transplantation in 1963, development of the procedure evolved at first slowly and steadily for 20 years and then rapidly over the past two decades. The growth of liver transplantation was facilitated by the conclusion of the national institutes of health consensus development conference in 1983 that liver transplantation is not an experimental procedure but an effective therapy that deserves broader application. The number of liver transplantations increased 2.4-fold(from 1.713 to 4.058) from 1988 to 1996. but the number of patients on the UNOS(united network of organ sharing) liver list increased 12.1-fold(from 616 to 7,467); as would be expected, the number of deaths of listed patients increased 4.9-fold(from 195 to 954), The current supply of donor livers is insufficient to meet this need, and organ donation has been stagnant or increased by only a few percent in recent years. These facts underscore the importance of the appropriate selection of candidates for liver transplantation and the development of operative procedures, such as living donor liver transplant, split liver transplant and auxiliary partial liver transplant.
