This study was designed to find some potential natural products and/or constituents inhibiting proinflammatory cytokine generation in lung inflammation, since cytokines such as tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) are pivotal for provoking airway inflammation. In our preliminary screening procedure, the 70% ethanol extract of the leaves of Perilla frutescens (PFE) was found to clearly inhibit TNF-alpha production in the lung at 100 mg/kg, after intranasal lipopolysaccharide treatment of mice. Based on this result, ten constituents including phenylpropanoids (allyltetramethoxybenzene, caffeic acid, dillapiole, elemicin, myristicin, nothoapiole, rosmarinic acid methyl ester, rosmarinic acid) and monoterpenes (perilla aldehyde and perilla ketone) were successfully isolated from the extract. Among them, elemicin and myristicin were found for the first time to concentration-dependently inhibit IL-1beta-treated IL-6 production from lung alveolar epithelial cells (A549) at concentrations of 10-100 microM. These findings suggest that the phenylpropanoids including elemicin and myristicin have the potential to be new inhibitory agents against lung inflammation and they may contribute, at least in part, to the inhibitory activity of PFE on the lung inflammatory response.

PURPOSE: The purpose of this study is to identify the incidence of clavicle fracture in birth trauma associated with delivery, fetal presentation, birth weight and to identify the difference of the prognosis of clavicle fracture when immobilization was performed or not. MATERIALS AND METHODS: Among the 12,738 live births from March 1996 to December 2000, we reveiwed retrospectively the medical records and radiographs of 39 cases of clavicle fracture which were followed for more than 6 months. Statistical analysis was measured P-value. Except 11 cases that diagnosis was delayed, 27 cases were treated with figure of 8-bandage, and 1 case, which was combined with humerus fracture, was treated with long arm cast. RESULTS: Among 39 cases infants of clavicle fracture, 36 cases (0.57%) were delivered through vaginal delivery, 3 cases (0.04%) through ceasarean section. Fetal presentations were cephalic presentation in 29 cases, shoulder dystocia in 8 cases, breech presentation in 2 cases. The mean birth weight was 3.8 kg, the high prevalence (8.5%) was identified on large birth weight infants more than 4 kg (p<0.05). The fracture site was proximal portion in 12 cases, middle portion in 27 cases and right clavicle in 24 cases, left clavicle in 13 cases and both clavicle in 1 case. The combined injuries were the brachial plexus palsy (2 cases), skull fracture (1 case) and cephalhematoma (1 case). Finally all cases of clavicle fracture were shown radiographically bony union within 3 weeks. CONCLUSION: The newborn clavicle fractures were remarkably low incidence in cesarean section delivery and were easily neglected, and were detected accidentally on simple chest X-ray that was performed for upper respiratory infection. As a conclusion, it is necessary of screening test through careful physical examination and X-ray interpretation.

BACKGROUND: This study was purposed to identify the knowledge and performance level of the infection control guidelines and to improve their performance level of infection control for those nurses who care patients directly. METHODS: This study was based on the survey questionnaires about infection control guidelines with the total 626 nurses in Seoul and Kyunggi areas for the period between May 26, 2003 and July 14, 2003. RESULTS: The average knowledge level of infection control was 0.84 +/-0.07 (score range 0-1) and the average performance level of the infection control was 4.44+/-10.27 (score range 0-5). The correlation between knowledge and performance of the infection control showed positive correlation (r=.39; P<.001). The knowledge and performance level of the 'Prevention of the central catheter infection' were higher than other infection control guidelines. The performance levels of the 'Prevention of the surgical site infection' were lower than other infection control guidelines. The correlation between knowledge and performance of the 'Prevention of the nosocomial pneumonia' (r=.389; P<.001). 'Prevention of the urinary tract infection' (r=.325; P<.001), 'Prevention of the central catheter infection (r=.290; P<.001) and 'Intravascular infection control' (r=.446; P<.001) showed positive correlation. CONCLUSION: The study demonstrated that the nurses' knowledge and performance of infection control guidelines showed positive correlation. So the education on the infection control is required indispensably and it would contribute to reduce the hospital infection rate by performing the right treatment on the infection control with the basis of accurate knowledge.

The Korean Journal of Orthodontics 2021;51(6):419-427
Objective:
The purpose of this study was to evaluate the esthetic preference for various Korean silhouette profiles.
Methods:
The Korean average male and female profiles were modified by changing the lower facial height and anteroposterior lip position to produce nine types of profiles. In order to test intrarater reliability, the average profile was copied once more to be included for evaluation. A questionnaire containing 10 profiles for each sex, each of which had to be rated for preference on a numerical rating scale from 0 to 10, was administered to 30 adult orthodontic patients, 30 dental students, 30 orthodontists, and 30 dentists excluding orthodontists. The data were statistically analyzed using the intraclass correlation coefficient (ICC), independent t-test, and one-way ANOVA.
Results:
The ICC of overall intrarater reliability was 0.629. For several profiles, significantly higher scores were given to male profiles than to female profiles (p < 0.05). However, no significant differences were found in the scores for all profiles among the four rater groups.Among the short profiles, a significantly higher score was given to the retruded profile, and among the vertically average and long profiles, a significantly higher score was given to the horizontally average profile (p < 0.001). Among all the profiles, significantly lower scores were given to the protruded profile (p < 0.001).
Conclusions
This study revealed good overall intrarater reliability, with several types of male profiles being esthetically preferred over female profiles. Moreover, while retruded and horizontally average profiles were generally preferred, protruded profiles were not.

The Korean Journal of Internal Medicine 2021;36(1):214-222
Background/Aims:
To explore the associations between body composition and pain, disease activity, and disability in rheumatoid arthritis (RA).
Methods:
The study enrolled 335 patients with RA and underwent body composition measurement with an InBody analyzer. The associations of body mass index (BMI), body fat mass, and skeletal muscle mass with disease activity score in 28 joints (DAS28), an index derived to measure the subjective component of DAS28 (DAS28-P), a pain visual analogue scale (VAS), and disability measured with the health assessment questionnaire (HAQ) were explored. Obesity was defined as BMI ≥ 25 kg/m2
Results:
The median (interquartile range) disease duration was 6 years (3.5 to 9) and the mean DAS28 score was 3.6 ± 1.1. The mean BMI was 23.6 ± 3.6 kg/m2 and 109 patients (32.5%) were obese. Compared with non-obese patients, obese patients had a higher C-reactive protein (1.68 mg/dL vs. < 0.1 mg/dL, p = 0.013), higher pain VAS score (40 vs. 35, p = 0.031), and higher DAS28-erythrocyte sedimentation rate score (3.75 ± 1.18 vs. 3.46 ± 1.11, p = 0.031). In multivariate regression analysis, the DAS28 score in females was positively associated with the current steroid dose, body fat mass, and HAQ score, while the HAQ score in females was associated with older age, DAS28, lower skeletal muscle mass, and higher body fat/skeletal muscle ratio. In the multivariate regression analysis, the DAS28-P score in females was positively associated with body fat/skeletal muscle ratio and HAQ.
Conclusions
Body composition, such as the body fat mass and body fat/skeletal muscle ratio, is significantly associated with disease activity and disability in female RA patients.

Allergy, Asthma & Respiratory Disease 2023;11(2):72-76
Purpose:
This study aimed to describe the desperate situation where the clinician should make decisions to further manage patients having experienced adverse drug reaction (ADR) to lamotrigine that is indicated to not easily controlled neuropsychiatric diseases.
Methods:
A descriptive analysis was done by thoroughly reviewing medical records of patients who were reported to have ADR to lamotrigine in a regional drug-safety center between 2010 and 2018.
Results:
Eighty-four cases of lamotrigine-related ADRs occurred in 80 patients. Skin lesions were most commonly observed in 70 cases (83.3%) and 14 cases (16.7%) had severe ADRs. Sixty-three subjects (78.8%) discontinued lamotrigine, while 17 (21.3%) continued it.At the time of discontinuation, 30.0% were prescribed aromatic antiepileptic drugs. Among 4 subjects who were eventually prescribed lamotrigine again after a period of discontinuation, 3 (75.0%) experienced its recurrence. Among patients who had taken alternative medications, the incidence of ADRs was higher in those being prescribed aromatic antiepileptic drugs than in the others being prescribed other than aromatic antiepileptic drugs (P = 0.013). Regarding the control of underlying diseases, as many as 65 (86.7%) and 68 (90.7%) failed to reach maintaining the resolved state from 6 months and 12 months after the substitution, respectively.
Conclusion
Patients can be easily trapped between the recurrence of ADRs and the treatment failure to a certain drug like lamotrigine, in which we can hardly find a reasonable alternative to manage them.

BACKGROUND: Initial evaluation of injury severity in trauma patients is an important and challenging task. We aimed to assess whether easily measurable biochemical parameters (hemoglobin, pH, and prothrombin time/international normalized ratio [PT/INR]) can predict in-hospital mortality in patients with severe trauma. METHODS: This retrospective study involved review of the medical records of 315 patients with severe trauma and an injury severity score >15 who were managed at Gyeongsang National University Hospital between January 2005 and December 2015. We extracted the following data: in-hospital mortality, injury severity score, and initial hemoglobin level, pH, and PT/INR. The predictive values of these variables were compared using receiver operation characteristic curves. RESULTS: Of the 315 patients, 72 (22.9%) died. The in-hospital mortality rates of patients with hemoglobin levels <8.4 g/dl and ≥8.4 g/dl were 49.8% and 9.9%, respectively (P < 0.001). At a cutoff hemoglobin level of 8.4 g/dl, the sensitivity and specificity values for mortality were 81.9% and 86.4%, respectively. At a pH cutoff of 7.25, the sensitivity and specificity values for mortality were 66.7% and 77.8%, respectively; 66.7% of patients with a pH <7.25 died versus 22.2% with a pH ≥7.25 (P < 0.001). The in-hospital mortality rates for patients with PT/INR values ≥1.4 and <1.4 were 37.5% and 16%, respectively (P < 0.001; sensitivity, 37.5%; specificity, 84%). CONCLUSIONS: Using the suggested cutoff values, hemoglobin level, pH, and PT/INR can simply and easily be used to predict in-hospital mortality in patients with severe trauma.

Journal of Korean Neurosurgical Society 2005;38(3):206-210
OBJECTIVE: Our aim is to evaluate the early changes of biologic markers such as white blood cell(WBC) count, erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP) in early diagnosis of postoperative infection and to differentiate infection from inflammatory reaction in lumbar spine surgery. METHODS: We reviewed 330patients who had undergone spinal operations between May 1999 and October 2001. For this study, the patients were classified into two groups, which include a group that underwent spinal decompressive surgery without instrumentation(SD), and the other group that underwent fusion surgery with spinal instrumentation(SI). And each group was also subdivided into two groups respectively, one with infection and the other without infection. We retrospectively analyzed the WBC count, ESR and CRP preoperatively and postoperatively, according to their operation type and postoperative infection history. RESULTS: Inflammatory indices were physiologically affected by instrumentation itself. But ESR and CRP elevations were more prolonged and sustained under infection. In SD patients without infection, ESR and CRP were stabilized 5 days after surgery. In SI patients without infection, CRP was stabilized about 7days after surgery, but ESR showed sustained and variously elevated. In both SD and SI groups, the stabilization of CRP was the most reliable behavior of surgery without infection. CONCLUSION: C-reactive protein is most sensitive parameter for postoperative spine infection. The knowledge of the inflammatory indices and their relatively uniform patterns with or without infection offers surgeons the ability to infer the state of surgical wound.

BACKGROUND: Topoisomerase II (TOPO II) is an enzyme that separates intertwined chromosomes during DNA synthesis by transiently breaking and joining DNA strands. The level of TOP II is one of the determinants of cellular sensitivity to anti-tumor drugs in non-Hodgkin's lymphoma patients. The alpha form of TOPO II has been recently used as a marker of cellular proliferation. High levels of TOPO IIalpha are expressed in aggressive and proliferative tumors. METHODS: This study was designed to evaluate the relationship between TOPO IIalpha expression and clinicopathological parameters including age, gender, the serum LDH level, the serum beta2-microglobulin level and stage, or expressions, of Ki-67, p53 and p27, in non-Hodgkin's lymphoma. We analyzed forty-one biopsied tissue specimens from patients with non-Hodgkin's lymphoma. RESULTS: The expression of TOPO IIalpha increased with the clinical stage and it was correlated with Ki-67 and p53 expressions. However, TOPO IIalpha expression did not have any significant correlation with age, gender, the serum LDH level, the serum 2-microglobulin level and the p27 expression. CONCLUSIONS: TOPO IIalpha expression is a useful marker of cellular proliferation and it may serve as a prognostic factor of a tumor's progression and aggressiveness in non-Hodgkin's lymphomas.
