PURPOSE: Pain is the most common and influential symptom in cancer patients. Few studies concerning pain intensity in the terminally ill cancer patients have been done. This study aimed to identify factors related with more than moderate pain. METHODS: This study used secondary data of 162 terminal cancer inpatients at the palliative ward of six training hospitals in Korea. Physician-assessed pain assessment was by 10 point numeric rating scale. Substantial pain was defined more than moderate intensity by the Korean National Guideline for cancer pain. The Korean version of the MD Anderson Symptom Inventory was self-administered to assess symptoms. Survival prediction was estimated by the attending physicians at the time of admission. RESULTS: Less than six weeks of predicted survival and more than numeric rating of six for worst drowsiness in the previous 24 h were significantly related to substantial pain (P=0.012 and P=0.046, respectively). The dose of opioid analgesics was positively related to substantial pain (P=0.004). CONCLUSION: Factors positively related to substantial pain were less than six weeks of predicted survival and considerable drowsiness. Careful monitoring and active preparation for pain are required in terminal cancer patients having those factors.

BACKGROUND: Facet joint is an important structure not only contributing to the stability of the lumbar motion segments but also causing low back pain. Hypothetically, the more lumbar lordosis decreases, the more corresponding facet joints orient axially and asymmetrically. Furthermore, the increased incidence of common diseases possessed of low back pain and radiologic findings such as wedging of vertebral body and spondylolisthesis were reported in the patients with asymmetric orientation of the facet joints and loss of lumbar lordosis at the same time. The purpose of our study is to define the relationship of asymmetry of the facet joints and loss of lumbar lordosis. METHODS: The asymmetry and average angle of facet joints with respect to sagittal plane were measured on the magnetic resonance images. The lumbar lordosis was measured on the lateral X-ray. The relevance of lumbar lordosis and facet orientation was analyzed through linear regression. RESULTS: There were no significant relationships between lumbar lordosis and asymmetrical orientation of facet joint. CONCLUSIONS: The loss of lumbar lordosis did not suggest asymmetrical and axial orientation of facet joints. Further investigation into pathology and consideration into individual differences of range of motion, body mass index, age, sex might be needed.

The present study aimed to investigate the osteogenic potentials of differentiated osteoblast-like cells (DOCs) induced from bone marrow-derived mesenchymal stem cells (MSCs) on beta-tricalcium phosphate (beta-TCP) with recombinant human bone morphogenetic protein (rhBMP-2) in vitro. Osteoblast differentiation was induced in confluent cultures by adding 100 nM dexamethasone, 10 mM beta-glycerophosphate, 50 mM L-ascorbic acid. The Alizarin red S staining and reverse transcriptase-polymerase chain reaction (RT-PCR) were perfomed to examine the mRNA expression of alkaline phosphatase (ALP), bone sialoprotein (BSP), osteocalcin (OCN), receptor activator for nuclear factor kappaB ligand (RANKL), runt-related transcription factor 2 (RUNX2), collagen-I (COL-I). There were no significant differences in the osteogenic potentials of DOCs induced from MSCs on beta-TCP(+/-). According to the incubation period, there were significant increasing of Alizadin red S staining in the induction 3 weeks. The mRNA expression of ALP, RUNX2, and RANKL were higher in DOCs/beta-TCP(-) than DOCs/beta-TCP(+). According to rhBMP-2 concentrations, the mRNA expression of BSP was significantly increased in DOCs/beta-TCP(+) compared to that of DOCs/beta-TCP(-) on rhBMP 10 ng/ml. Our study presented the beta-TCP will have the possibility that calcium phosphate directly affect the osteoblastic differentiation of the bone marrowderived MSCs.

BACKGROUND: Smoking prevention and anti-smoking education in schools must be designed and planned according to age and sex as well as the type of schools and their smoking status. But the current education programs do not consider these factors. This study, therefore, aims to evaluate the actual status of the smoking prevention and anti-smoking education in Korea and to find present recommendations for an effective and, systematic education. METHODS: We surveyed 15,310 teen-age students attending middle schools and high schools in such cities as Seoul, Incheon, Bucheon, Mokpo, and Pohang and smaller areas in the vicinity of these cities from June 1 to 15, 2005. Self-survey was done by the health education teacher of each school. It contained questions about the general disposition of respondents, their smoking habits, and awareness programs on prevention and cessation of smoking. We used SPSS 12.0 for chi-square-test to analyze the collected data. RESULTS: The most prevailing form of anti-smoking education was "video". Most of the students surveyed said that the fourth or fifth grade of elementary school will be a good starting point for anti-smoking education. Only 39.6% of students who were educated by the current smoking prevention and anti-smoking program answered that it was "helpful" and 29.6% was "satisfied". Higher percentage of middle school students said that they either tried to quit smoking ('pre-contemplation') or had no intention of doing it ('termination-fail') after having been involved in the anti-smoking education program, while high school students turned out to be more oriented towards 'contemplation' and 'termination-success'. CONCLUSION: Some students were found to begin smoking even at an early grade in elementary school. Most adolescents knew about the danger of smoking, but current smokers had a low educational satisfaction. The real target of such education programs, however, should be focused on higher grade students in elementary schools and middle school students, because data show that smoking rate increases explosively among these students.

Objectives: During Le Fort I osteotomy, the separation of the pterygomaxillary junction (PMJ) is a difficult procedure for most surgeons because it is invisible. In this process, damage to the posterior structures constituting the sinus or those adjacent to it, including the maxillary sinus posterior wall and pterygoid plate, may occur. We would like to investigate the effects of this on the inside of the maxillary sinus after surgery and whether there are complications. Materials and Methods: One-hundred patients who underwent Le Fort I osteotomy from 2013 to 2020 using cone-beam computed tomography images were classified into two groups (clean-cut type and fractured type) according to the PMJ cutting pattern. In addition, the mucosal thickness in the maxillary sinus was divided into preoperative, postoperative three months, one year, and the change over the course of surgery was evaluated retrospectively. Results: Of the total 100 cases, the clean-cut type numbered 28 cases and the fractured type totaled 72 cases. Among the fracture types, part of the sinus wall and the pterygoid plate were broken in 69 cases, and the maxillary sinus posterior wall was detached in three cases. There was no statistically significant difference in sinus mucosal thickening between the clean-cut type and fractured type of the PMJ, three months and one year after surgery between the two groups. However, there was a significant difference in sinus mucosal thickness at postoperative one year in the case where a partial detachment of the maxillary sinus posterior wall occurred compared to not. Conclusion Even if there is some damage to the structures behind the PMJ, it may not be reasonable to spend some time on the PMJ separation process considering the overall postoperative complications, if there is no significant difference inside the sinus, or increased probability of postoperative complications.

Purpose: This study examined the effects of nutritional education related to sugar in elementary school children on nutritional knowledge, attitude, and dietary behavior. Methods: A questionnaire survey on the knowledge, attitudes, and intake related to sugar was conducted on 572 students in grades 4–5, who were attending five elementary schools in Seoul and Gyeonggi-do. Results: Among the survey subjects, 270 (49.8%) were cognitive in education, and 302 (50.2%) were non-cognitive. The sugar-related knowledge score was 3.67 points in the cognitive education group, which was significantly higher than the 3.55 points in the non-cognitive group. The rate of checking the sugar content in the nutrition label was 31.2% in the cognitive education group, which was significantly higher than in the non-cognitive group, 15.4%. The cognitive education group had a higher intake frequency of unsweetened candy, jelly, and raw fruits, and higher sugar intake of unsweetened bread, white milk, and raw fruits than the non-cognitive group. In the case of the cognitive education group, the total knowledge score showed a positive correlation with the food behavior scores, and a negative correlation with the frequency of purchasing snacks after school, and the average sugar intake per day. In the cognitive education group only, the education of nutrition teachers was analyzed as a factor to reduce the total sugar intake. The cognitive group of sugar education tried to eat foods with a lower sugar content than the non-cognitive group, and nutrition education was an important factor affecting the sugar intake. Conclusion To reduce the sugar intake of elementary school students, it will be necessary to practice oriented-nutrition education by nutrition teachers continuously. In addition, it is important to develop and disseminate various types of nutrition education materials related to sugar that can be utilized easily by nutrition teachers.

Nontuberculous mycobacterial (NTM) diseases are increasing worldwide. However NTM lung disease in organ transplant recipients has been rarely reported. Here, we report 2 cases of NTM lung disease in heart transplant recipients. A 37-year-old man, who had undergone a heart transplant one year previous, was admitted to hospital due to a cough. Chest CT scan showed multiple centrilobular nodules in both lower lungs. In his sputum, M. abscessus was repeatedly identified by rpoB gene analysis. The patient improved after treatment with clarithromycin, imipenem, and amikacin. An additional patient, a 53-year-old woman who had undergone a heart transplant 4 years prior and who suffered from bronchiectasis, was admitted because of purulent sputum. The patient's chest CT scan revealed aggravated bronchiectasis; M. intracellulare was isolated repeatedly in her sputum. Treatment was successfully completed with clarithromycin, ethambutol, and ciprofloxacin. NTM lung disease should be considered as a potential opportunistic infection in organ transplant recipients.

The aspiration of a tracheobronchial foreign body can be a life-threatening incident. Early diagnosis and the bronchoscopic removal of the foreign bodies can protect a patient from serious morbidity and even mortality. We report an unusual case of a 28-year-old man who inhaled sawdust that required emergency airway management and bronchoscopic removal of the sawdust fragments. Anesthesia for a rigid bronchoscopy is a challenging procedure for an anesthesiologist who must share the airway with the bronchoscopist and maintain the adequate depth of anesthesia. Most of the sawdust fragments were extracted successfully using a rigid bronchoscope. The patient was discharged uneventfully within one week of hospitalization.
