  • Objectives: This study was aimed to figure out an agreement between the diagnosis of nasal endoscopy and a preexisting questionnaire focusing on Cold-Heat pattern. Methods: 52 patients with cough who met the criteria filled out a pattern questionnaire and the examiner looked at their nasal cavities through nasal endoscopy. According to the checked questionnaire results, the subjects were identified by 6 patterns. After examining subject's mucous membrane of oropharynx and nasal cavity through nasal endoscopy, we classified each to the Cold or Heat group. Correlation between questionnaire and nasal endoscopy results was analyzed. Results: In diagnosing Cold-Heat, there was no significant difference by McNemar test (p=0.227) between nasal endoscopy and the questionnaire, and the two methods agreed moderately (${\kappa}=0.428$). The color of mucous membrane of oropharynx and the Cold-Heat pattern on questionnaire agreed slightly (${\kappa}=0.133$). The color of mucous membrane of nasal cavity and the Cold-Heat pattern on questionnaire agreed fairly (${\kappa}=0.384$). In the patients with cough related to upper respiratory tract, they got higher diagnosis accuracy than the patients with cough related to lower respiratory tract did. Similarly, external cough patients got higher diagnosis accuracy than internal cough patients did. Conclusions: To identify Cold or Heat, examining oropharynx and nasal cavity using nasal endoscopy is a meaningful method in patients with cough, showing that two diagnosis methods which use nasal endoscopy and questionnaire agreed moderately. Especially, it is more useful diagnosing patients with cough related to the upper respiratory tract than diagnosing the patients with cough related to the lower respiratory tract.

  • This study investigated the degree of self-care practice to maintain the stable respiratory function and the required respiratory nursing needs upon the elderly with chronic obstructive pulmonary diseases. The research subjects were 115 elderly people over 60 years old, who were diagnosed to have chronic obstructive pulmonary diseases (the mixed type, chronic bronchitis, bronchial asthma, emphysema) and were hospitalized in 3 university hospitals in Busan or treated as outpatient, and the data was collected over the period between June 1, 2002 and September 30, 2002. In order to measure the respiratory self-care practice degree and nursing needs of the subjects, the instrument on the self-care practice and the instrument on nursing needs were developed by the researcher. The research results are as follows: 1. The mean of respiratory self-care practice degree by the subjects was 2.41 out of 4 for each clause, and the degree of practicing general management was the highest(2.70), and nutrition control(2.66), respiratory exercise(2.65), expectoration of sputum (2.63), oxygen therapy(2.60), environment control(2.50), and medication control(2.36) succeeded. 2. The degree of self-care practice had a significant difference depending on age(F=2.82, P=0.02), frequency of hospitalization(F=3.11, P=0.01), and diagnosed disease(F=15.66, P=0.00). 3. The subjects nursing needs of respiratory system were 3.07 on the average out of 4.00, and 'I want to know how to prevent the infection of respiratory system such as cold scored the highest 3.83, while the clauses like 'want to know how to face the respiratory disorder properly'(3.77) and 'want the specific explanation of the symptoms of my disease'(3.66) also had scored high points. 4. The nursing needs of the respiratory system had a significant difference depending on diagnosed disease such as mixed type of chronic obstructive pulmonary diseases, emphysema, bronchitis, and asthma (F=6.70, P=0.00). The research showed that the subjects degree of self-care practice of respiratory system was low on the whole, while the nursing needs for managing respiratory organ were relatively high. Therefore, specific education concerning the nursing of the disease and self-care upon the elderly having chronic obstructive pulmonary disease is necessary.

  • Background: Vibration response imaging (VRI) is a new technology that records energy generated by airflow during the respiration cycle. Analysis of lung sound using VRI may overcome the limitations of auscultation. Objectives: To set a VRI standard for healthy Koreans, we conducted a clinical assessment to evaluate breath sound images and quantification in healthy subjects and compared the findings with reported breath sound characteristics. Methods: Recordings were performed using the VRIxp. Eighty subjects took a deep breath four times during a 12-second interval while sitting upright. The quantitative aspect was analyzed using the VRI quantitative lung data (QLD) for total left lung, total right lung and for six lung regions: left upper lung (LUL), left middle lung (LML), left lower lung (LLL), right upper lung (RUL), right middle lung (RML), right lower lung (RLL). The qualitative aspect was provided through image assessments by three reviewers. Results: In all regions the left lung had significantly higher QLD than the right lung (P<0.005, paired t-test). The inter-rater agreement was 0.78. 84% of the images were found normal by the final assessment. Among the 16% (n=13) of images with abnormal final assessment, the most common flawed features were dynamic image (77%, n=10) and maximum energy frame (MEF) shape (77%, n=10). No significant differences were found between males and females for QLD but there were significant differences in qualitative aspects including dynamic images, MEF shape, and missing LLL. Conclusion: The characteristics of healthy Koreans are similar to those of Western subjects reported previously. VRI is easy to use and objective, and so is helpful to diagnose patients with respiratory diseases and to monitor the progress of diseases after medical treatments.

  • Lung cancer 환자 중 호흡에 의한 종양의 움직임이 큰 lung lower lobe에서 stetreotactic radiosurgery(SRS)시 호흡 주기 중 종양의 움직임이 적은 호흡 주기에서만 방사선을 조사하기 위해 respiratory gating system을 사용함으로써 그 유용성에 대하여 알아보고자 한다. lung lower lobe의 SRS 환자 2명을 대강으로 하였으며, 환자의 복부에 maker block(sensor)을 부착하고 tracking camera와 real time position management(RPM)를 이용하여 호흡 주기를 측정하면서 1회 호흡주기에서 10 phases의 4D-CT를 촬영 하였다. 종양의 위치 변화가 급격하지 않은 percent($\%$)의 phases를 치료 phases로 결정하였고, 치료 phases의 CT image를 maximum intensity projection(MIP) 기법으로 재구성 후 volume contouring을 하였다. set up 의 재현성 및 GTV의 위치 변화를 확인하기 위해 치료 전과 치료 중 2회의 4D-CT 촬영을 하였다. GTV의 움직임이 가장 큰 Y(longitudinal)축에서 A환자 full($0\%\~90\%$) phases의 9.4mm가 치료 ($30\%\~60\%$) phases 에서는 2.6mm로, B환자 full($0\%\~90\%$) phases의 11.7mm가 치료($30\%\~70\%$) phases 에서는 2.3mm로 줄었다. 2회의 4D-CT 비교 결과 Set up의 X, Y, Z축 오차는 모두 3mm 이내였다. 호흡에 의한 종양의 움직임이 큰 lung lower lobe에서 SRS 시행 시 respiratory gating system의 사용은 종양의 움직임을 5mm 이내로 감소시킬 수 있어 유용하였다.

  • In cardiac magnetic resonance imaging (CMRI), heart and respiratory motions are one of main obstacles in obtaining diagnostic quality of images. To synchronize CMRI to the physiological motions, ECG and respiratory gatings are commonly used. In this paper multi-biological signal (ECG, respiratory, and SPO2) based smart trigger system is proposed. By using multi-biological signal, the proposed system is robust to the induced noise such as eddy current when gradient pulsing is continuously applied during the examination. Digital conversion of the multi-biological signal makes the system flexible in implementing smart and intelligent algorithm to detect cardiac and respiratory motion and to reject arrhythmia of the heart. The digital data is used for real-time trigger, as well as signal display, and data storage which may be used for retrospective signal processing.

  • Objectives This study was designed to analyze the characteristics of craniofacial hyperhidrosis and palmar/plantar hyperhidrosis by nasal endoscopy and body composition test. Methods The study sample consisted of 20 and 22 patients with craniofacial hyperhidrosis and palmar/plantar hyperhidrosis, respectively, who answered questionnaires and underwent nasal endoscopy and body composition test. The questionnaires estimated the quality of life by Dermatology Life Quality Index score (DLQI), and the degree of obesity was evaluated using body mass index (BMI), percent body fat (PBF), and waist-hip ratio (WHR). The state of nasal cavity was evaluated by color, humidity, and swelling of the mucous membranes, and runny nose. Results BMI, PBF, and WHR were higher in patients with craniofacial hyperhidrosis than in patients with palmar/plantar hyperhidrosis. Rhinitis score was not significantly different between craniofacial hyperhidrosis and palmar/plantar hyperhidrosis. There was a positive correlation between rhinitis score and DLQI. Conclusions The degree of obesity was higher in patients with craniofacial hyperhidrosis than in those with palmar/plantar hyperhidrosis. The state of nasal cavity was not significantly different between craniofacial hyperhidrosis and palmar/plantar hyperhidrosis, but was associated with quality of life of hyperhidrosis patients.
