  • We examined 104 patients(primary group, controlled group) who had visited PNUH from 1994 to 2002, having been diagnosed as temporomandibular disorders(TMDs) and treated in conservative ways such as Behavior modification, medications, physical therapies and splint therapies. We also examined 54 patients(recurred group, experimental group) who had visited PNUH from 1991 to 2001, having been diagnosed as TMDs and experienced recurrence after conservatively treated. To find out the symptoms of Recurred TMD patients and their results of conservative treatments, we compared these two groups mentioned above. The obtained results were as follows: 1. Both primary and recurred groups have showed great improvements with conservative treatments. 2. Both primary and recurred groups have showed no differences in pain, LOM, MCO in their first visits but the noise were louder in primary group. 3. Both primary and recurred groups have showed no differences in pain, LOM, MCO when the treatments were over but the noise were louder in recurred group. 4. Treatments modalities, diagnosis, sex, kind of disease had not affected the results of treatment in either of groups. 5. It has come out that much better results were achieved when the patients in primary group had treated for over 6 months and for more than 10 times.

  • The purpose of this study was to find out prevalence of peg-laterals and to evaluate the frequency of dental anomalies in Korean children with peg-laterals. For this study, panoramic radiographs of 3,278 patients (aged 7 to 15 years) from the Department of Pediatric Dentistry admitted from January, 2008 to January, 2013 were selected for an investigation on peg-laterals distribution. The prevalence of peg-laterals was 2.62% (86 subjects). Among the peg-laterals children, the distribution of associated dental anomalies were as follows: congenitally missing teeth (29.1%), dens invaginatus (19.8%), impacted teeth (12.8%), supernumerary teeth (9.3%), and transposition (4.7%). Due to this study showing frequent occurrences of peg-laterals with other dental anomalies, one suggestion is to consider such relationships before deciding on a diagnosis and treatment plan.

  • A primary pulmonary leiomyosarcoma is a very rare pulmonary malignancy that arises from smooth muscle of either the bronchial or arterial walls. Common symptoms of the tumor are cough, dyspnea, chest pain and hemoptysis. The diagnosis of a primary pulmonary sarcoma can be established only after extensive clinical and radiologic examinations have failed to identify an alternative primary source. The only effective treatment for the tumor is a complete surgical resection when feasible. The type of resection is dictated by the local anatomic extent of the tumor. We report a case of a 21-year-old male with a primary endobronchial leiomyosarcoma who presented with massive hemoptysis. A necrotic ulcerative endobronchial lesion was observed in the orifice of left lower lobe bronchus on a bronchoscopic examination. He was treated with a complete sleeve resection of the left lower lobe. Three months later, local recurrence of the tumor was noticed on the follow up bronchoscopy and a then left pneumonectomy was then performed. Fifteen months later, the patient died from empyema with a bronchopleural fistula that was associated with tumor recurrence at the stump of the pneumonectomy.

  • The purpose of this study was to find out the recent trend of high-tech AAC intervention studies for individuals with disabilities. Electronic database searches were completed to identify studies published between 2009 and 2016. 46 studies were identified for inclusion in this review. The studies were classified as participants, research design, intervention settings, independent variables, dependent variables, communication skills by High-tech device, type of high-tech AAC device. Across these studies, intervention was provided to total of 126 participants. Most participants are aged 6-11 and the most common diagnosis was autistic spectrum disorder. Most common study designs were multiple probe design and multiple treatment design. The majority of studies implemented interventions in a special education school(classroom) setting. The majority of studies implemented interventions to compare the effect of high-tech and low-tech AAC device interventions. The majority of targeted behavioral outcomes were communication skills. Tablet PC was the most frequently used for intervention in both domestic and foreign studies. The most common softwares were 'My talky' in domestic studies and 'Proloquo2Go' in foreign studies. The synthesis of evidence describing views of users and providers and the implementation of high-tech AAC device can provide valuable data to inform intervention studies and functional outcome measures. Suggestions for the future research are discussed.

  • This Study aims at looking into the use of oriental medical services in treating hypertension. The first objective to be explored through this study is the morbidity caused by the disease, classifying them by age, gender, and occupation. The second is to determine the regular use of anti-hypertensive medicine and their efficacy in controlling blood-pressure. The third is to investigate the use-rate and satisfaction of oriental medical service. 838 households across the country, were asked to answer questionnaires for the period of time from Apr. to Jun. 2005. The conclusion from the survey can be summarized as following. The age of which the first medical diagnosis of hypertension were made showed lower in males, those with higher education and income. The study showed females were more active in blood-pressure control, with their frequent monitoring of blood-pressure for the past year. With age, people in under 50 age group proved to be less active. The management of high blood pressure was more effective in group with regular dosage compared to group with irregular use of anti-hypertensive medication, but their difference was minimal. Also, group with no medication showed signs of blood-pressure control. The use of oriental medical service for the past year, were more frequent in groups with lower education, either low or high income, old age, females and occupations in agriculture, forestry and fishing industry. Results were similar in both general population and high blood-pressure patient group. Females, people over 51 years old and with lower education showed more intentions in utilizing oriental medical services in the future. Results were similar in both general population and high blood-pressure patient group. It is necessary to offer a more accurate information on oriental medical treatments. Also, a systematic reform to reduce the patient's share of the treatment cost, as well as, heightening public awareness on the infirmity of present blood-pressure management system is crucial.

  • Anti-N-methyl-D-aspartate receptor (Anti-NMDAR) encephalitis is a neuroinflammatory disease mediated by autoantibodies to NMDAR. In the initial clinical stages of anti-NMDAR encephalitis, psychiatric symptoms like delusions, perceptual disturbances, and disorganized speech or behaviors are pronounced even without obvious neurological symptoms. Early treatments like immunotherapy and/or tumor removal are central to good clinical outcomes. Hence, it is important to diagnose early anti-NMDAR encephalitis, distinguishing it from mental disorder. In the present case study, the authors described psychiatric symptoms assessed with Positive and Negative Syndrome Scale (PANSS) of Ms. A, a 26-year-old woman, in the early phase of anti-NMDAR encephalitis. We will discuss the characteristic psychopathology of anti-NMDAR encephalitis toward prompt diagnosis and treatment. Ms. A showed a higher negative subscale score than positive one on the PANSS. Compared with mental disorder, negative symptoms and cognitive impairment would be more prominent in the early stage of anti-NMDAR encephalitis. Rituximab and teratoma removal were effective, and quetiapine showed good tolerability. It is recommended to evaluate anti-NMDAR encephalitis when negative symptoms, cognitive impairment, catatonia, changes in consciousness level, and neurological symptoms are observed, especially in young women.

  • Purpose: According to American Society of Clinical Oncology/College of American Pathologists guidelines, breast cancer is human epidermal growth factor receptor 2 (HER2) positive if there is HER2 protein overexpression at a 3+ level on immunohistochemistry (IHC 3+) or gene amplification (more than six copies per nucleus) on fluorescence in situ hybridization (FISH+). However, there have been few reports on whether outcomes differ based on diagnosis by these two techniques. In this study, we compared outcomes based on the two methods in patients with HER2-positive breast cancer. Methods: This study was a retrospective analysis of HER2-positive breast cancer in 18,304 patients, including 14,652 IHC 3+ patients and 3,652 FISH+ patients from the Korean Breast Cancer Society Registry. We compared breast cancer-specific survival and overall survival based on IHC 3+ and FISH+ status with or without trastuzumab. Results: Breast cancer-specific survival was significantly different between the IHC 3+ and FISH+ groups, with 5-year cumulative survival rates of 95.0% for IHC 3+ and 98.5% for FISH+ patients who did not receive trastuzumab (p=0.001) in Kaplan-Meier methods. However, there were no significant differences in breast cancer-specific survival and overall survival between IHC 3+ and FISH+ groups regardless of trastuzumab treatment in Cox proportional hazards models. Conclusion: The survival outcomes were not affected by the different two diagnostic methods of HER2-positive breast cancer. Further research to evaluate differences in prognosis and other characteristics according to the diagnostic methods of HER2 positivity is needed in the future.

  • This study investigates the current situation of medical technologists for blood collection, which is considered the most important step for diagnosis. The survey enrolled 650 medical technologists working in hospitals and medical check centers in Busan, Ulsan, and Gyeongnam. We found that each medical technologist performed blood collection for about 100 patients. There was more than one blood collection failure per day, with more than one case of pain and filing of civil complaints per year. Hence, there was a high work burden on the medical technologists. Cases where a medical technologist was stabbed with a used needle occurred more than once a year, and about 15% of them received infection control and treatment because of stab wounds. Additionally, more than half of the participants suffered from musculoskeletal disorders and mental stress due to blood collection work. Unlike administering intravenous and intramuscular injections using the same needle, no fee is charged for blood collection. Based on the results of this study, it will be possible to improve the safety and rights of medical technologists by calculating the actual fee for blood collection work and assigning a relative value score.

  • Research using AI and big data is also being actively conducted in the health and medical fields such as disease diagnosis and treatment. Most of the existing research data used cohort data from research institutes or some patient data. In this paper, the difference in the prediction rate of survival and the factors affecting survival between breast cancer patients in their 40~50s and other age groups was revealed using health insurance review claim data held by the HIRA. As a result, the accuracy of predicting patients' survival was 0.93 on average in their 40~50s, higher than 0.86 in their 60~80s. In terms of that factor, the number of treatments was high for those in their 40~50s, and age was high for those in their 60~80s. Performance comparison with previous studies, the average precision was 0.90, which was higher than 0.81 of the existing paper. As a result of performance comparison by applied algorithm, the overall average precision of Decision Tree, Random Forest, and Gradient Boosting was 0.90, and the recall was 1.0, and the precision of multi-layer perceptrons was 0.89, and the recall was 1.0. I hope that more research will be conducted using machine learning automation(Auto ML) tools for non-professionals to enhance the use of the value for health insurance review claim data held by the HIRA.
