BACKGROUND AND OBJECTIVE: The outcome of asthma treatment has traditionally been assessed by measuring the conventional clinical parameters such as symptoms, expiratory flow rates and needs for medications. But none of them tells us whether the patients are actually able to function properly in their lives. Only assessment of the quality of life (QOL) can reflect the parts of patients lives affected by the disease. However, there is no measure to assess the quality of life of patients with any chronic diseases in Korea yet. We developed the QOL Questionnaire for Korean Asthmatics and evaluated its measurement properties. METHOD: The questionnaire was composed of 18 items in four domains : i.e. activity limitation (6 items), symptoms (5 items), emotional function (3 items) and environmental stimuli (4 items). At our out-patient clinic, 32 adults with moderate to severe persistent bronchial asthma were enrolled. The study design consisted of 4 week unblinded single cohort with visits at 0 and 4 weeks, and the patients were asked to answer the questionnaire by self administration method at the two separate visits. Forced expiratory volume for 1 second (FEV1) and peak expiratory flow rate (PEFR) were recorded at each visit. According to the patients and physicians global assessment, the patients were divided into two groups, i.e. stable and changed (improved). The responsiveness, reproducibility and validity of the questionnaire were evaluated. RESULTS: The total QOL scores at the second visit in the changed group were significantly higher than those at the first visit. The score differences between the two visits in the changed group were higher than in the stable group. In the stable group, the responses to the questionnaire were reproducible. The QOL scores showed good longitudinal correlation with the expiratory flow rates, whereas FEV1 did not correlate with the QOL in cross-sectional analysis. CONCLUSION: The questionnaire proved to be reproducible, responsive and valid in the subjects. It could be recommended for the outcome evaluation of Korean asthmatics.

This study was performed to observe the effect of ultrasound(1.0MHz, 0.75W/cm2 and 1.0W/cm2) irradiation on cultured MC3T3-E1 cell, osteoblastic like cell with respect to the proliferation, protein synthesis, and alkaline phosphatase activity of the cells. The results were as follows: 1. The proliferation of MC3T3-E1 cells was increased on ultrasound irradiated group compared with control group. 2. The protein synthesis was not apparently increased on ultrasound irradiated group compared with control group. 3. The alkaline phosphatase activity level was not apparently increased on ultrasound irradiated group compared with control group. From the above results and other literatures, we could suggest that the ultrasound with the appropriate intensity and frequency may have important roles in stimulation of cell proliferation. Therefore the ultrasound may be used in the acceleration of the bone regeneration and bone fracture healing.

3.A Systematic Review of Non-pharmacological Interventions for Delirium Prevention in Elderly Inpatients
Journal of Korean Academy of Fundamental Nursing 2021;28(2):249-262
Purpose:
The study was aimed to examine components and provider’s characteristics of non-pharmacological intervention that affect delirium prevention in elderly inpatients. Additional effects on delirium prevention based on identified characteristics were explored.
Methods:
Studies were searched by using seven electronic databases and examined through Preferred Reporting Items Systematic Review and Meta-Analysis (PRISMA) flow diagram. The Risk of Bias (ROB) and the Risk of Bias Assessment tool for Non-randomized Study (RoBANS) were used to evaluate the quality of each included study.
Results:
Seven studies were selected for the systematic review. Most of the selected studies had a low risk of bias. Interventions of each study and delirium outcome were heterogeneous. Each multi-component non-pharmacological intervention consisted on average of five interventions. Giving orientation and promoting early mobilization were included in every study. Interventions that included giving orientation, promoting early mobilization, and supporting nutrition significantly decreased delirium incidence. Moreover, when health care providers who have an intimate relationship with patients provided non-pharmacological interventions, delirium incidence has significantly decreased.
Conclusion
Non-pharmacological intervention, such as giving orientation, promoting early mobilization, should be included to prevent delirium for elderly inpatients. It is important to include healthcare providers who have an intimate relationship or regular contact with patients in order to decrease delirium incidence.

A 70-year-old female Patient was admitted due to the impression of lung abscess via local clinic. Chest P-A showed air shadow containing huge mass lesion in the right lower lung field, pericardio phrenic angle. But the patient complained of only mild upper respiratioy tract infection symptoms and the laboratory tests were within normal limits. Barium enema and chest C-T taken right after barium enema were performad in suggesting of the diaphragmatic hernia. Barium tilled transverse colon and associated omentum were in the right anterior hemithorax surrounded by the hernial sac. The mass lesion shown in the chest P-A was compatible with the diaphragmatic hemia, Morgagni type. Operative reduction of the herniated bowel and simple closure of the diaphragm was performed.

A 42-year-old man presented with severe pancytopenia and uncontrolled epistaxis. The diagnosis of SLE was made and the pancytopenia was found to be due to myelofibrosis. The pulse therapy with methylprednisolone and maintenance therapy with prednisolone reversed both pancytopenia and myelofibrosis. Although myelofibrosis has been described in SLE, this coexistence must be very rare since there has been only 19 cases showing this combination. We report a case of SLE with myelofibrosis which was reversed by the treatment with glucocorticoid.

There have been no known therapeutic modalities as effective as glucocorticoids for the treatment of chronic intractable atopic dermatitis. However, various attempts including phototherapy with UVB irradiation have been tried to avoid side effects from long term corticosteroids treatment. The therapeutic effect of UVB irradiation in the management of chronic atopic dermatitis was examined. Sixteen patients with atopic dermatitis showing severe itching and lichenified lesions, who were dependent on corticosteroids, were treated with UVB. After applying mineral oil or vaseline, patients received phototherapy. Intractable pruritus subsided or ameliorated after mean 5.2 times of treatments in 10 of 11 patients, and the skin lesions disappeared or improved after mean 13 times of treatments in 9 of 10 patients. No side effects were observed. UVB phototherapy could be avaluable alternate for the treatment of intractable atopic dermatitis.

In the RNA-based study, it is important to extract high-quality RNA. However, RNA extraction from Mycobacterium tuberculosis is problematic due to its thick, waxy cell wall rich in mycolic acid, which renders the cells resistant to lysis. Using TRIzol reagent and several powerful bead-beating steps, a high quantity of RNA was obtained.

BACKGROUND: Obesity is defined as an excess accumulation of body fat. To measure body fat accurately is difficult, but body mass index (BMI, kg/m2) is easily available for routine clinical use. METHODS: A total of 4,966 (male; 2,580, female; 2,386) patients from January to September in 1997 and aged up to 90 years old were studied for BMI. Among these subjects, obstetric patients were excluded in our study. We calculated the BMI as weight (kg) per height squared (m2). The heights and weights of study subjects were obtained from anesthesia records. The BMI was analyzed by 4 different age groups: group 1 (less than 3 years), group 2 (between 3 to 7 years), group 3 (between 8 to 17 years), and group 4 (18 years or more), decade of age, 4 obesity categories according to BMI levels: underweight (less than 18 kg/m2), normal weight (19-24.9 kg/m2), overweight (25-29.9 kg/m2), and obese (30 kg/m2 or more), and surgical departments. RESULTS: Mean BMI values of group 1, 2, 3, and 4 were 16.1+/-2.9 kg/m2, 16.2+/-2.4 kg/m2, 19.2+/-3.7 kg/m2 and 23.3+/-4.6 kg/m2 in males and 15.7+/-3.9 kg/m2, 15.8+/-2.7 kg/m2, 19.4+/-3.5 kg/m2 and 23.6+/-3.7 kg/m2 in females, respectively. According to generations, the BMI under teen-age was 16.3+/-2.7 kg/m2 and 14.3+/-2.9 kg/m2 in males and females respectively while it was between 20.4+/-3.3 kg/m2 to 25.0+/-3.6 kg/m2 from 1st to 7th decade patients in both sex. The prevalence of overweight and obesity were nearly zero in group 1 and 2, but males in group 3 had them of 4.6% and 1.4% while 6.9% and 0.8% in females, respectively. In group 4 they were 25.3% and 2.2% in males and 28.8% and 4.8% in females, respectively. Obese patients increased in the order of neurosurgery, gynecology, orthopedic surgery, urology, and general surgery departments. CONCLUSIONS: This study revealed the guidelines of BMI of operating patients. We recognized that the prevalence of overweight and obesity of preschool aged and adolescent patients were nearly zero. Adult patients were the highest at 4th decade in males and 6th decade in females and the obesity rates were 27.4% and 33.6% in males and females, respectively.

PURPOSE: Little is known about the isometry of anatomic single-bundle anterior cruciate ligament (ACL) tunnel positions in vivo although it is closely related to graft tension throughout the range of motion. The purpose of this study was to evaluate intraoperative graft isometry in anatomic single-bundle ACL reconstruction in vivo. MATERIALS AND METHODS: Graft length changes were assessed before bio-screw fixation in the tibial tunnel by pulling the graft with tensions of 20 lbs and 30 lbs in full extension at flexion angles of 30°, 60°, 90°, and 120°. RESULTS: At the flexion angle of 30°, 20 lbs and 30 lbs of tension showed −0.4 mm and −0.6 mm length changes, respectively. The greater the flexion angle of the knee, the shorter the graft length in the joint. At the flexion angles of 90° and 120°, there was significant difference in the graft length change between 20 lbs and 30 lbs of tension. CONCLUSIONS: Anatomic single-bundle ACL reconstruction was non-isometric. The graft length was the longest in full extension. The tension of graft became loose in flexion. At the flexion angles of 90° and 120°, there was significant difference in the graft length change between 20 lbs and 30 lbs of tension.
